具体实施方式DETAILED DESCRIPTION
(第一实施例)(First embodiment)
(1)概述(1) Overview
首先，将参考图1和图4来说明根据典型实施例的通用串行总线(USB)插座10的概述。First, an overview of a universal serial bus (USB) socket 10 according to an exemplary embodiment will be described with reference to FIGS. 1 and 4 .
根据典型实施例的USB插座10是装置9的USB连接器91可连接到的装置。USB插座10是用于在USB连接器91连接到USB插座10的状态下经由USB连接器91向装置9(诸如智能电话等)供给电力的装置。装置9利用从USB插座10供给的电力例如对装置9中所包括的蓄电池92(参见图4)进行充电。The USB socket 10 according to the typical embodiment is a device to which the USB connector 91 of the device 9 is connectable. The USB socket 10 is a device for supplying power to the device 9 (such as a smartphone) via the USB connector 91 in a state where the USB connector 91 is connected to the USB socket 10. The device 9 charges, for example, a battery 92 (see FIG. 4 ) included in the device 9 using the power supplied from the USB socket 10.
根据本实施例的USB插座10是要装配到诸如建筑物的壁等的对象结构物81上的布线装置。这样的USB插座10以及用于输出例如100V或200V的AC电压的一般AC插座始终电连接到电源(诸如电网等)，并且基本上始终处于通电状态。这使得用户能够仅仅通过将装置9连接到USB插座10来从USB插座10经由USB连接器91向装置9供给电力。The USB socket 10 according to the present embodiment is a wiring device to be mounted on a target structure 81 such as a wall of a building. Such a USB socket 10 and a general AC socket for outputting an AC voltage of, for example, 100 V or 200 V are always electrically connected to a power source (such as a power grid) and are basically always in a powered-on state. This enables a user to supply power to a device 9 from the USB socket 10 via the USB connector 91 simply by connecting the device 9 to the USB socket 10.
在这种情况下，例如，用于输出100V或200V的AC电压的一般AC插座在对诸如智能电话等的装置9充电时，需要使用用于将AC电压转换成DC电压的电源适配器，以向装置9供给电力。相比之下，根据本实施例的USB插座10使得能够通过在无需使用任何电源适配器的情况下将装置9的USB连接器91直接连接到USB插座10来向装置9供给电力。因此，USB插座10使得用户即使在他或她没有随身携带电源适配器的情况下也能够对诸如智能电话等的装置9充电。另外，不需要电源适配器可以使USB插座10的周围环境干净整齐。In this case, for example, a general AC outlet for outputting an AC voltage of 100V or 200V requires the use of a power adapter for converting the AC voltage into a DC voltage when charging a device 9 such as a smartphone, etc., to supply power to the device 9. In contrast, the USB outlet 10 according to the present embodiment enables power to be supplied to the device 9 by directly connecting the USB connector 91 of the device 9 to the USB outlet 10 without using any power adapter. Therefore, the USB outlet 10 enables the user to charge the device 9 such as a smartphone, etc., even if he or she does not carry a power adapter with him or her. In addition, the absence of a power adapter can make the surrounding environment of the USB outlet 10 clean and tidy.
根据本实施例的USB插座10包括连接部2、电源电路11、壳体3和警报单元102。装置9的USB连接器91可电连接到连接部2。电源电路11从连接部2向装置9供给电力。壳体3在内部容纳电源电路11。警报单元102在发现监视值大于阈值时发出警报。监视值是以下项中的至少一个：要供给到装置9的电流的大小、要供给到装置9的电流的累计值、要供给到装置9的电力的大小、要供给到装置9的电能、以及向装置9供给电力的时间长度。The USB socket 10 according to the present embodiment includes a connection portion 2, a power circuit 11, a housing 3, and an alarm unit 102. The USB connector 91 of the device 9 can be electrically connected to the connection portion 2. The power circuit 11 supplies power to the device 9 from the connection portion 2. The housing 3 accommodates the power circuit 11 inside. The alarm unit 102 issues an alarm when it is found that the monitoring value is greater than a threshold value. The monitoring value is at least one of the following items: the magnitude of the current to be supplied to the device 9, the cumulative value of the current to be supplied to the device 9, the magnitude of the power to be supplied to the device 9, the electric energy to be supplied to the device 9, and the length of time for which power is supplied to the device 9.
根据该配置，在诸如从电源电路11要供给到装置9的电流的大小等的监视值变得大于阈值时，警报单元102发出警报。因此，如果从USB插座10向装置9供给例如比电源电路11的额定输出(电流或电力)大的过大电流或电力，则可以向用户警报这样的异常。这使得能够针对诸如要供给到装置9的电流的大小等的监视值的任何异常向用户提供早期警报，由此有助于提高USB插座10的可靠性。因此，可以提供更有效地有助于提高可靠性的USB插座10。According to this configuration, when a monitoring value such as the magnitude of the current to be supplied from the power supply circuit 11 to the device 9 becomes greater than a threshold value, the alarm unit 102 issues an alarm. Therefore, if an excessive current or power, for example, greater than the rated output (current or power) of the power supply circuit 11 is supplied from the USB socket 10 to the device 9, the user can be alerted of such an abnormality. This makes it possible to provide an early warning to the user for any abnormality of the monitoring value such as the magnitude of the current to be supplied to the device 9, thereby contributing to improving the reliability of the USB socket 10. Therefore, a USB socket 10 that more effectively contributes to improving reliability can be provided.
(2)详细结构(2) Detailed structure
将参考图1至图4来说明根据本实施例的USB插座10的详细结构。The detailed structure of the USB socket 10 according to the present embodiment will be described with reference to FIGS. 1 to 4 .
(2.1)前提(2.1) Prerequisites
如本文所使用的，“USB”是指作为串行总线标准其中之一的通用串行总线(USB)标准。如本文所使用的“USB标准”可以是例如包括USB 1.0、USB 1.1、USB 2.0、USB 3.0、USB3.1、USB 3.2和USB 4的各代USB标准(分别具有不同的传输速率规格)中的任一个。另外，根据本发明的USB插座与各种端子形状(就其连接端口4的形状和与USB插座兼容的USB连接器91的形状而言)中的任何端子形状兼容。与USB插座兼容的端子形状的示例包括Type-A端子、Type-B端子和Type-C端子、诸如迷你USB端子和微型USB端子等的其他端子、以及它们的组合。具体地，兼容USB端子形状的示例包括迷你USB Type-A端子和微型USB Type-B端子。在以下的说明中，除非另外说明，否则将说明USB插座被设计为接受USB Type-A端子的实施例。在以下的说明中，这种USB端子形状规格在下文有时将被称为“USB连接器标准”。As used herein, "USB" refers to the Universal Serial Bus (USB) standard, which is one of the serial bus standards. As used herein, the "USB standard" may be, for example, any of the various generations of USB standards (each with different transmission rate specifications) including USB 1.0, USB 1.1, USB 2.0, USB 3.0, USB 3.1, USB 3.2, and USB 4. In addition, the USB socket according to the present invention is compatible with any terminal shape in various terminal shapes (in terms of the shape of its connection port 4 and the shape of the USB connector 91 compatible with the USB socket). Examples of terminal shapes compatible with the USB socket include Type-A terminals, Type-B terminals, and Type-C terminals, other terminals such as mini USB terminals and micro USB terminals, and combinations thereof. Specifically, examples of compatible USB terminal shapes include mini USB Type-A terminals and micro USB Type-B terminals. In the following description, unless otherwise specified, an embodiment in which the USB socket is designed to accept USB Type-A terminals will be described. In the following description, this USB terminal shape specification will sometimes be referred to as a "USB connector standard" below.
如本文所使用的，“装置的USB连接器”可以是形成装置9的一体部分的连接器、或者是设置在可连接到装置9的USB线缆的前端的连接器。也就是说，装置9的USB连接器可以是作为装置9的附件的连接器，诸如与装置9分开设置且经由线缆连接到装置9的连接器等。此外，如本文所使用的，“连接器”可以指要插入到插孔中的“插头”或者插头插入到的“插孔”，无论哪种都是适当的。在以下的说明中，除非另外说明，否则将说明装置9的USB连接器91是设置在可连接到装置9的USB线缆的前端的USB插头的实施例作为示例。As used herein, a “USB connector of a device” may be a connector that forms an integral part of the device 9, or a connector that is provided at a front end of a USB cable that can be connected to the device 9. That is, the USB connector of the device 9 may be a connector that is an accessory of the device 9, such as a connector that is provided separately from the device 9 and connected to the device 9 via a cable, etc. Furthermore, as used herein, a “connector” may refer to a “plug” to be inserted into a receptacle or a “receptacle” into which the plug is inserted, whichever is appropriate. In the following description, unless otherwise specified, an embodiment in which the USB connector 91 of the device 9 is a USB plug provided at a front end of a USB cable that can be connected to the device 9 will be described as an example.
同样，如本文所使用的“连接部”是指任何结构物，只要装置9的USB连接器91可电连接到该结构物即可。因此，如本文所使用的“连接部”可以指插头插入到的“插孔”或要插入插孔中的“插头”，无论哪种都是适当的。在以下的说明中，除非另外说明，否则将说明USB插座10的连接部2是具有连接端口4的插孔的实施例作为示例。也就是说，在以下要说明的典型实施例中，装置9的USB连接器91是USB插头，并且USB插座10的连接部2是USB插头可连接到的插孔。因此，USB插座10的壳体3具有的连接端口4包括在连接部2中。Likewise, the "connection portion" as used herein refers to any structure as long as the USB connector 91 of the device 9 can be electrically connected to the structure. Therefore, the "connection portion" as used herein may refer to a "receptacle" into which a plug is inserted or a "plug" to be inserted into the receptacle, whichever is appropriate. In the following description, unless otherwise specified, an embodiment in which the connection portion 2 of the USB socket 10 is a receptacle having a connection port 4 will be described as an example. That is, in the typical embodiment to be described below, the USB connector 91 of the device 9 is a USB plug, and the connection portion 2 of the USB socket 10 is a receptacle to which the USB plug can be connected. Therefore, the connection port 4 that the housing 3 of the USB socket 10 has is included in the connection portion 2.
如本文所使用的，“装置”是指可电连接到USB插座10且接收从USB插座10供给的电力的电气装备(其可以是装置、设施或系统)。装置9的示例包括诸如智能电话、平板计算机和可穿戴终端等的移动通信装置、移动电池、移动电话、照相机、循环器、手电筒和TV接收器。USB插座10通过向装置9施加DC电压来向装置9供给DC电力，因此装置9与DC输入兼容。在这种类型的各种装置9中，诸如智能电话、平板终端和可穿戴终端等的装置9各自包括蓄电池92，并且具有利用从USB插座10供给的电力对其蓄电池92充电的能力。在以下的说明中，具有对蓄电池92充电的能力的这种装置9在下文有时将被称为“可充电装置”。在以下的说明中，除非另外说明，否则将说明连接到USB插座10的装置9是可充电装置9的实施例作为示例。As used herein, "device" refers to electrical equipment (which may be a device, facility, or system) that can be electrically connected to a USB socket 10 and receives power supplied from the USB socket 10. Examples of device 9 include mobile communication devices such as smart phones, tablet computers, and wearable terminals, mobile batteries, mobile phones, cameras, circulators, flashlights, and TV receivers. The USB socket 10 supplies DC power to the device 9 by applying a DC voltage to the device 9, so the device 9 is compatible with DC input. Among various devices 9 of this type, devices 9 such as smart phones, tablet terminals, and wearable terminals each include a storage battery 92 and have the ability to charge its storage battery 92 using power supplied from the USB socket 10. In the following description, such a device 9 having the ability to charge the storage battery 92 will sometimes be referred to as a "rechargeable device" below. In the following description, unless otherwise specified, an embodiment in which the device 9 connected to the USB socket 10 is a rechargeable device 9 will be described as an example.
在本实施例中，USB插座10安装并固定到对象结构物81上。如本文所使用的，“对象结构物”是指USB插座10固定到的构件。对象结构物的示例包括诸如壁、天花板和地板等的建筑组件以及诸如书桌、桌子、架子和厨房柜台等的家具(包括配件)。USB插座10可以配备在例如住宅设施(诸如单户住宅和多户住宅等)和非住宅设施(诸如办公室、商店、学校、工厂、医院和护理设施等)中。在本实施例中，假定USB插座10是要安装到对象结构物81上的嵌入式布线装置，该对象结构物81例如可以是住宅设施的壁。特别地，假定USB插座10是要在建筑物内部使用的室内布线装置。In the present embodiment, the USB socket 10 is mounted and fixed to the object structure 81. As used herein, "object structure" refers to a member to which the USB socket 10 is fixed. Examples of object structures include building components such as walls, ceilings, and floors, and furniture (including accessories) such as desks, tables, shelves, and kitchen counters. The USB socket 10 can be equipped in, for example, residential facilities (such as single-family homes and multi-family homes) and non-residential facilities (such as offices, stores, schools, factories, hospitals, and nursing facilities). In the present embodiment, it is assumed that the USB socket 10 is an embedded wiring device to be installed on the object structure 81, which can be, for example, a wall of a residential facility. In particular, it is assumed that the USB socket 10 is an indoor wiring device to be used inside a building.
在以下的说明中，在USB插座10固定到作为示例性对象结构物81的住宅设施的壁上的状态下垂直于水平面(即，与水平面成直角相交)的方向在下文将被称为相对于USB插座10的“上/下方向”。此外，在USB插座10的前视图中位于USB插座10的下半部分中的部分在下文将被称为USB插座10的“下部”。垂直于上/下方向且平行于对象结构物81的表面(壁面)的方向在下文将被称为相对于USB插座10的“右/左方向”。在前视图中位于USB插座10的右方的一侧在下文将被称为USB插座10的“右侧”。在前视图中位于USB插座10的左方的另一侧在下文中将被称为USB插座10的“左侧”。此外，垂直于上/下方向和右/左方向这两者的方向(即，垂直于对象结构物81的表面(壁面)的方向)在下文将被称为相对于USB插座10的“前/后方向”。位于对象结构物81的背面的一侧(即，壁后方的一侧)在下文将被称为USB插座10的“背侧”。注意，这些方向不应被解释为限制使用USB插座10的方向。In the following description, the direction perpendicular to the horizontal plane (i.e., intersecting the horizontal plane at right angles) in a state where the USB socket 10 is fixed to the wall of a residential facility as an exemplary target structure 81 will be referred to as the "up/down direction" relative to the USB socket 10 hereinafter. In addition, the portion located in the lower half of the USB socket 10 in the front view of the USB socket 10 will be referred to as the "lower portion" of the USB socket 10 hereinafter. The direction perpendicular to the up/down direction and parallel to the surface (wall surface) of the target structure 81 will be referred to as the "right/left direction" relative to the USB socket 10 hereinafter. The side located to the right of the USB socket 10 in the front view will be referred to as the "right side" of the USB socket 10 hereinafter. The other side located to the left of the USB socket 10 in the front view will be referred to as the "left side" of the USB socket 10 hereinafter. In addition, the direction perpendicular to both the up/down direction and the right/left direction (i.e., the direction perpendicular to the surface (wall surface) of the target structure 81) will be referred to as the "front/rear direction" relative to the USB socket 10 hereinafter. The side located at the back of the target structure 81 (ie, the side behind the wall) will be hereinafter referred to as the “back side” of the USB socket 10. Note that these directions should not be interpreted as limiting the directions in which the USB socket 10 is used.
此外，在USB插座10固定到作为对象结构物81的住宅设施的壁上的状态下，USB插座10的壳体3的正面31基本上面向前方。然而，这不必意味着壳体3的正面31始终朝向前方。例如，如果USB插座10安装到天花板上，则壳体3的正面31朝向下方。Furthermore, in a state where the USB socket 10 is fixed to the wall of a residential facility as the target structure 81, the front surface 31 of the housing 3 of the USB socket 10 faces substantially forward. However, this does not necessarily mean that the front surface 31 of the housing 3 always faces forward. For example, if the USB socket 10 is mounted on a ceiling, the front surface 31 of the housing 3 faces downward.
如本文所使用的，如果彼此比较的两个值其中之一“等于或大于”另一个，则该短语在本文可以涵盖这两个值彼此相等的情形和这两个值中的一个大于另一个的情形。然而，这不应被解释为限制性的。可替代地，短语“等于或大于”也可以是仅涵盖两个值中的一个超过另一个的情形的短语“大于”的同义词。也就是说，不论短语“等于或大于”是否涵盖两个值彼此相等的情形，根据基准值或任何预设值的选择，该短语都是可任意改变的。因此，从技术角度来看，短语“等于或大于”和短语“大于”之间没有差异。类似地，短语“小于”也可以是短语“等于或小于”的同义词。As used herein, if one of two values being compared is "equal to or greater than" the other, the phrase herein may cover both situations where the two values are equal to each other and situations where one of the two values is greater than the other. However, this should not be construed as limiting. Alternatively, the phrase "equal to or greater than" may also be a synonym of the phrase "greater than" which only covers situations where one of the two values exceeds the other. That is, regardless of whether the phrase "equal to or greater than" covers situations where the two values are equal to each other, the phrase may be arbitrarily changed depending on the selection of a reference value or any preset value. Therefore, from a technical point of view, there is no difference between the phrase "equal to or greater than" and the phrase "greater than". Similarly, the phrase "less than" may also be a synonym of the phrase "equal to or less than".
(2.2)基本结构(2.2) Basic structure
接着，将参考图1至图3的B来说明根据本实施例的USB插座10的基本结构。Next, the basic structure of the USB socket 10 according to the present embodiment will be described with reference to FIG. 1 to FIG. 3B .
如上所述，根据本实施例，USB插座10可以是要安装到对象结构物81上的嵌入式布线装置，该对象结构物81例如可以是住宅设施的壁。也就是说，USB插座10是被配置为固定到对象结构物81上并且可连接到通过对象结构物81后方的线L1(参见图4)的布线装置。特别地，该USB插座10是如下嵌入式布线装置，其中壳体3以部分地嵌入到在对象结构物81中设置的装配窗孔82(参见图3的A)中的状态固定到对象结构物81上。As described above, according to the present embodiment, the USB socket 10 may be an embedded wiring device to be mounted on the target structure 81, which may be, for example, a wall of a residential facility. That is, the USB socket 10 is a wiring device configured to be fixed to the target structure 81 and connectable to the line L1 (see FIG. 4 ) passing behind the target structure 81. In particular, the USB socket 10 is an embedded wiring device in which the housing 3 is fixed to the target structure 81 in a state of being partially embedded in the mounting window hole 82 (see FIG. 3 A) provided in the target structure 81.
另外，USB插座10还包括线L1连接到的端子部16(参见图4)。将在(作为示例性对象结构物81的)壁内部延伸的线L1连接到端子部16使得USB插座10能够通过线L1电连接到诸如电网等的电源。例如，线L1可以直接地或经由配电盘间接地连接到电源(诸如电网等)。In addition, the USB socket 10 further includes a terminal portion 16 (see FIG. 4 ) to which the wire L1 is connected. Connecting the wire L1 extending inside the wall (as the exemplary object structure 81) to the terminal portion 16 enables the USB socket 10 to be electrically connected to a power source such as a power grid through the wire L1. For example, the wire L1 may be directly connected to a power source (such as a power grid) or indirectly connected via a distribution board.
在本实施例中，将线L1连接到端子部16使得USB插座10能够经由线L1电连接到例如单相100V、60Hz的商用AC电源(即，电网)。在这种情况下，USB插座10经由配电盘连接到AC电源(电网)。如果配电盘的断路器(包括主干断路器和分支断路器)通电，则USB插座10也通电。因此，基本上，USB插座10始终准备好向装置9供给电力。In the present embodiment, connecting the line L1 to the terminal portion 16 enables the USB socket 10 to be electrically connected to, for example, a single-phase 100V, 60Hz commercial AC power source (i.e., a power grid) via the line L1. In this case, the USB socket 10 is connected to the AC power source (power grid) via a distribution board. If the circuit breakers (including the main circuit breaker and the branch circuit breaker) of the distribution board are powered on, the USB socket 10 is also powered on. Therefore, basically, the USB socket 10 is always ready to supply power to the device 9.
此外，在以下要说明的典型实施例中，作为示例，将说明两个USB连接器91可连接到的双端口USB插座10。也就是说，根据本实施例的USB插座10包括USB连接器91连接到的多个(例如，在该示例中为两个)连接部2(包括连接端口4)，并且可以从这些多个连接部2向装置9供给电力。因此，USB插座10可以在多个装置9的USB连接器91连接到USB插座10的状态下同时向多个装置9供给电力。在以下的说明中，当需要将多个(例如，在该示例中为两个)连接部2彼此区分开时，两个连接部2在下文有时将分别称为“第一连接部21”和“第二连接部22”。同样，当需要将多个(例如，在该示例中为两个)连接端口4彼此区分开时，两个连接端口4在下文有时将分别称为“第一连接端口41”和“第二连接端口42”。Furthermore, in the typical embodiment to be described below, as an example, a two-port USB socket 10 to which two USB connectors 91 can be connected will be described. That is, the USB socket 10 according to the present embodiment includes a plurality of (for example, two in this example) connection parts 2 (including connection ports 4) to which the USB connector 91 is connected, and power can be supplied to the device 9 from these plurality of connection parts 2. Therefore, the USB socket 10 can simultaneously supply power to the plurality of devices 9 in a state where the USB connectors 91 of the plurality of devices 9 are connected to the USB socket 10. In the following description, when it is necessary to distinguish the plurality of (for example, two in this example) connection parts 2 from each other, the two connection parts 2 will be referred to as "first connection part 21" and "second connection part 22" respectively hereinafter. Similarly, when it is necessary to distinguish the plurality of (for example, two in this example) connection ports 4 from each other, the two connection ports 4 will be referred to as "first connection port 41" and "second connection port 42" respectively hereinafter.
如图2的A和图2的B所示，USB插座10包括电源电路11和壳体3。图2的B以更大的比例例示图2的A所示的USB插座10中的第一连接端口41及其周围区域。As shown in Fig. 2A and Fig. 2B, the USB socket 10 includes a power circuit 11 and a housing 3. Fig. 2B illustrates the first connection port 41 and its surrounding area in the USB socket 10 shown in Fig. 2A on a larger scale.
电源电路11包括电路板(印刷线路板)和安装在该电路板上的各种电子组件。电源电路11将从AC电源(电网)施加到端子部16的AC电压转换成DC电压，并将DC电压输出到连接部2。这使得电源电路11能够从连接部2向装置9供给电力。如后面将详细说明的，控制单元101和其他组件(参见图4)也安装在电源电路11的电路板上。电源电路11可以仅包括单个电路板或多个电路板，无论哪种都是是适当的。The power circuit 11 includes a circuit board (printed wiring board) and various electronic components mounted on the circuit board. The power circuit 11 converts the AC voltage applied to the terminal portion 16 from the AC power supply (grid) into a DC voltage and outputs the DC voltage to the connection portion 2. This enables the power circuit 11 to supply power to the device 9 from the connection portion 2. As will be described in detail later, the control unit 101 and other components (see FIG. 4) are also mounted on the circuit board of the power circuit 11. The power circuit 11 may include only a single circuit board or a plurality of circuit boards, whichever is appropriate.
如上所述，壳体3固定到对象结构物81上。壳体3在内部容纳电源电路11。更确切地说，壳体3容纳电源电路11的电路板，由此不仅容纳电源电路11，而且还容纳控制单元101和其他组件。另外，不仅电源电路11和控制单元101、而且诸如连接部2和端子部16等的内部组件都适当地容纳在壳体3中。壳体3由具有电绝缘性质的合成树脂制成。As described above, the housing 3 is fixed to the object structure 81. The housing 3 accommodates the power circuit 11 inside. More specifically, the housing 3 accommodates the circuit board of the power circuit 11, thereby accommodating not only the power circuit 11 but also the control unit 101 and other components. In addition, not only the power circuit 11 and the control unit 101, but also internal components such as the connection portion 2 and the terminal portion 16 are appropriately accommodated in the housing 3. The housing 3 is made of a synthetic resin having an electrical insulating property.
在本实施例中，壳体3具有长方体形状，并且被形成为具有与具有三个模组尺寸的布线装置大致相同的尺寸。壳体3具有在壳体3安装到对象结构物81上的状态下向前方露出的正面31。在该示例中，壳体3的正面31具有矩形的形状，该矩形在上/下方向上的尺寸大于其在右/左方向上的尺寸。壳体3的正面31具有至少一个连接端口4。In the present embodiment, the housing 3 has a rectangular parallelepiped shape and is formed to have approximately the same size as a wiring device having a three-module size. The housing 3 has a front face 31 exposed to the front when the housing 3 is mounted on the target structure 81. In this example, the front face 31 of the housing 3 has a rectangular shape whose size in the up/down direction is larger than its size in the right/left direction. The front face 31 of the housing 3 has at least one connection port 4.
根据本实施例的USB插座10是双端口USB插座10，因此壳体3的正面31具有两个连接端口4。这两个连接端口4被布置成在上/下方向上彼此间隔开一定间隔。这两个连接端口4中的各连接端口4具有矩形的形状，其中如图2的A和图2的B所示，在前视图中该矩形在右/左方向上的尺寸大于其在上/下方向上的尺寸。也就是说，各连接端口4是横向细长孔。The USB socket 10 according to the present embodiment is a dual-port USB socket 10, so the front face 31 of the housing 3 has two connection ports 4. The two connection ports 4 are arranged to be spaced apart from each other in the up/down direction. Each of the two connection ports 4 has a rectangular shape, wherein as shown in FIG. 2A and FIG. 2B , the size of the rectangle in the right/left direction in the front view is larger than the size in the up/down direction. That is, each connection port 4 is a transversely elongated hole.
在各连接端口4内部，设置有金属壳、金属触点和其他构件。这使得连接端口4能够连同壳、触点和其他构件一起形成装置9的USB连接器91电连接和机械连接到的连接部2(插孔)。将USB连接器91从具有这种结构的连接部2的正面笔直地插入到连接部2中，这使得USB连接器91连接到连接部2。也就是说，将插入型的USB连接器91在限定插入方向的前/后方向上插入到连接端口4中，这使得USB连接器91电连接到且机械耦接到连接部2。Inside each connection port 4, a metal shell, metal contacts and other components are provided. This enables the connection port 4 to form, together with the shell, contacts and other components, a connection portion 2 (receptacle) to which the USB connector 91 of the device 9 is electrically and mechanically connected. The USB connector 91 is inserted straightly into the connection portion 2 from the front of the connection portion 2 having such a structure, which connects the USB connector 91 to the connection portion 2. That is, the insertion-type USB connector 91 is inserted into the connection port 4 in the front/rear direction defining the insertion direction, which connects the USB connector 91 electrically and mechanically to the connection portion 2.
另一方面，在连接部2和USB连接器91彼此连接的状态下将USB连接器91从连接部2笔直地拔出使得USB连接器91从连接部2断开。也就是说，将USB连接器91沿插入方向(前/后方向)从连接端口4移除，这解除了USB连接器91向连接端口4的电连接和机械耦接。简言之，用户可以通过使USB连接器91相对于在壳体3的正面31中设置的连接端口4插入或移除来选择性地使装置9(USB连接器91)相对于连接部2连接或断开连接。On the other hand, pulling the USB connector 91 straight out from the connecting portion 2 in a state where the connecting portion 2 and the USB connector 91 are connected to each other causes the USB connector 91 to be disconnected from the connecting portion 2. That is, the USB connector 91 is removed from the connecting port 4 in the insertion direction (front/rear direction), which releases the electrical connection and mechanical coupling of the USB connector 91 to the connecting port 4. In short, the user can selectively connect or disconnect the device 9 (USB connector 91) with respect to the connecting portion 2 by inserting or removing the USB connector 91 with respect to the connecting port 4 provided in the front face 31 of the housing 3.
在本实施例中，如图3的A所示，壳体3可移除地附接到用于将壳体3固定到对象结构物81上的安装支架84上。另外，如图3的A所示，插座板8进一步附接到安装支架84。在本实施例中，安装支架84和插座板8未被计入USB插座10的构成元件中。然而，这仅是示例，并且不应被解释为限制性的。可替代地，安装支架84和插座板8中的至少一个可被计入在USB插座10的构成元件中。In the present embodiment, as shown in A of FIG. 3 , the housing 3 is removably attached to a mounting bracket 84 for fixing the housing 3 to the target structure 81. In addition, as shown in A of FIG. 3 , the socket plate 8 is further attached to the mounting bracket 84. In the present embodiment, the mounting bracket 84 and the socket plate 8 are not counted in the constituent elements of the USB socket 10. However, this is merely an example and should not be construed as limiting. Alternatively, at least one of the mounting bracket 84 and the socket plate 8 may be counted in the constituent elements of the USB socket 10.
在本实施例中，USB插座10是如上所述的嵌入式布线装置，因此使用诸如嵌入式开关盒等的安装构件83安装到对象结构物81(例如，在该示例中为壁)上。也就是说，装配窗孔82设置在对象结构物81中，并且将USB插座10通过装配窗孔82安装到对象结构物81的背面(例如，在该示例中为壁后方)所布置的诸如开关盒等的安装构件83中。In this embodiment, the USB socket 10 is an embedded wiring device as described above, and is therefore mounted on a target structure 81 (for example, a wall in this example) using a mounting member 83 such as an embedded switch box. That is, a mounting window hole 82 is provided in the target structure 81, and the USB socket 10 is mounted through the mounting window hole 82 to a mounting member 83 such as a switch box arranged on the back side of the target structure 81 (for example, behind the wall in this example).
安装支架84例如可以是用于安装由日本工业标准进行标准化的大尺寸矩形连续底座布线装置的安装支架。具体地，安装支架84在前视图中是以矩形框的形状形成的。壳体3附接到安装支架84，使得壳体3位于安装支架84内。The mounting bracket 84 may be, for example, a mounting bracket for mounting a large-size rectangular continuous base wiring device standardized by the Japanese Industrial Standard. Specifically, the mounting bracket 84 is formed in the shape of a rectangular frame in a front view. The housing 3 is attached to the mounting bracket 84 so that the housing 3 is located inside the mounting bracket 84.
安装支架84可以由例如合成树脂制成。安装支架84具有一对安装孔841和一对板固定孔842。将一对安装螺钉843通过一对安装孔841紧固到诸如开关盒等的安装构件83上，这使得安装支架84能够安装到对象结构物81上。The mounting bracket 84 may be made of, for example, a synthetic resin. The mounting bracket 84 has a pair of mounting holes 841 and a pair of plate fixing holes 842. A pair of mounting screws 843 are fastened to a mounting member 83 such as a switch box through the pair of mounting holes 841, which enables the mounting bracket 84 to be mounted on the target structure 81.
插座板8包括装饰板85和固定板86。也就是说，在本实施例中，插座板8由装饰板85和固定板86这两个构件组成。插座板8(包括装饰板85和固定板86)可以由例如合成树脂制成。The socket plate 8 includes a decorative plate 85 and a fixing plate 86. That is, in the present embodiment, the socket plate 8 is composed of two components, the decorative plate 85 and the fixing plate 86. The socket plate 8 (including the decorative plate 85 and the fixing plate 86) can be made of, for example, synthetic resin.
固定板86固定在安装支架84上。装饰板85附接到固定板86以覆盖固定板86的正面。以这种方式，装饰板85经由固定板86间接地固定到附接有壳体3的安装支架84上。装饰板85具有窗孔801，其中在插座板8附接到安装支架84的状态下，壳体3的正面31通过窗孔801露出。The fixing plate 86 is fixed to the mounting bracket 84. The decorative plate 85 is attached to the fixing plate 86 to cover the front surface of the fixing plate 86. In this way, the decorative plate 85 is indirectly fixed to the mounting bracket 84 to which the housing 3 is attached via the fixing plate 86. The decorative plate 85 has a window hole 801 through which the front surface 31 of the housing 3 is exposed in a state where the socket plate 8 is attached to the mounting bracket 84.
也就是说，插座板8是具有窗孔801的框的形状的构件，并且与安装支架84组合，使得壳体3的正面31通过其窗孔801露出。换句话说，在安装支架84和插座板8彼此组合的状态下，在前视图中壳体3的正面31位于插座板8(的装饰板85的窗孔801)的内部。因此，在插座板8和壳体3这两者都安装到对象结构物81上的状态下，如图3的B所示，壳体3的周边部分被插座板8覆盖以防止安装支架84、装配窗孔82和其他构件露出。这改善了USB插座10的外观。That is, the socket plate 8 is a member in the shape of a frame having a window hole 801, and is combined with the mounting bracket 84 so that the front face 31 of the housing 3 is exposed through its window hole 801. In other words, in a state where the mounting bracket 84 and the socket plate 8 are combined with each other, the front face 31 of the housing 3 is located inside the window hole 801 of the decorative plate 85 of the socket plate 8 in the front view. Therefore, in a state where both the socket plate 8 and the housing 3 are mounted on the object structure 81, as shown in B of FIG. 3, the peripheral portion of the housing 3 is covered by the socket plate 8 to prevent the mounting bracket 84, the assembly window hole 82, and other members from being exposed. This improves the appearance of the USB socket 10.
更具体地，在前视图中装饰板85是以矩形框的形状形成的。窗孔801在前/后方向上贯通装饰板85的中央部。装饰板85通过卡扣装接可移除地机械耦接到固定板86。具体地，通过利用所使用的装饰板85和固定板86中的至少一个的弹性将针对从装饰板85和固定板86中选择的一个构件所设置的突起装配到针对另一构件所设置的孔中，装饰板85和固定板86彼此机械地耦接。More specifically, the decorative plate 85 is formed in the shape of a rectangular frame in a front view. The window hole 801 penetrates the central portion of the decorative plate 85 in the front/rear direction. The decorative plate 85 is removably mechanically coupled to the fixing plate 86 by snap-fitting. Specifically, by fitting a protrusion provided for one member selected from the decorative plate 85 and the fixing plate 86 into a hole provided for the other member by utilizing the elasticity of at least one of the decorative plate 85 and the fixing plate 86 used, the decorative plate 85 and the fixing plate 86 are mechanically coupled to each other.
此外，在前视图中固定板86是以矩形框的形状形成的。另外，固定板86具有一对通孔861。将一对固定螺钉844通过一对通孔861紧固到安装支架84的一对板固定孔842中，这使得固定板86能够附接到安装支架84。In addition, the fixing plate 86 is formed in the shape of a rectangular frame in the front view. In addition, the fixing plate 86 has a pair of through holes 861. A pair of fixing screws 844 are fastened to a pair of plate fixing holes 842 of the mounting bracket 84 through the pair of through holes 861, which enables the fixing plate 86 to be attached to the mounting bracket 84.
(2.3)USB插座的具体结构(2.3) Specific structure of USB socket
接着，将参考图2的A、图2的B和图4来说明根据本实施例的USB插座10的具体结构。Next, the specific structure of the USB socket 10 according to the present embodiment will be described with reference to FIG. 2A , FIG. 2B , and FIG. 4 .
如图4所示，根据本实施例的USB插座10不仅包括电源电路11、至少一个(例如，在该示例中为两个)连接部2、以及壳体3，而且还包括端子部16、控制单元101和警报单元102。控制单元101包括检测单元12和设置单元13。警报单元102包括显示单元14和声音发出单元15。端子部16、控制单元101和警报单元102中的至少一部分连同电源电路11一起容纳在壳体3中。As shown in FIG4 , the USB socket 10 according to the present embodiment includes not only a power supply circuit 11, at least one (for example, two in this example) connection portion 2, and a housing 3, but also includes a terminal portion 16, a control unit 101, and an alarm unit 102. The control unit 101 includes a detection unit 12 and a setting unit 13. The alarm unit 102 includes a display unit 14 and a sound emitting unit 15. At least a part of the terminal portion 16, the control unit 101, and the alarm unit 102 are accommodated in the housing 3 together with the power supply circuit 11.
电源电路11包括用于将AC电压转换成DC电压的AC/DC转换器电路。电源电路11插入在端子部16和连接部2之间，并且将从端子部16供给的AC电压转换成DC电压并将DC电压供给到连接部2。在该示例中，电源电路11将从AC电源(电网)施加到端子部16的100V的AC电压转换成5V的DC电压。结果，施加到端子部16的100V的AC电压由电源电路11转换成5V的DC电压，该DC电压被供给到连接部2。The power supply circuit 11 includes an AC/DC converter circuit for converting an AC voltage into a DC voltage. The power supply circuit 11 is inserted between the terminal portion 16 and the connection portion 2, and converts the AC voltage supplied from the terminal portion 16 into a DC voltage and supplies the DC voltage to the connection portion 2. In this example, the power supply circuit 11 converts an AC voltage of 100V applied to the terminal portion 16 from an AC power source (grid) into a DC voltage of 5V. As a result, the AC voltage of 100V applied to the terminal portion 16 is converted by the power supply circuit 11 into a DC voltage of 5V, which is supplied to the connection portion 2.
在本实施例中，多个(例如，在该示例中为两个)连接部2连接到单个电源电路11。也就是说，将DC电压从电源电路11施加到第一连接部21和第二连接部22这两者。这使得能够将电源电路11的输出从多个(例如，在该示例中为两个)连接部2供给到装置9的USB连接器91。In the present embodiment, a plurality of (for example, two in this example) connection portions 2 are connected to a single power supply circuit 11. That is, a DC voltage is applied from the power supply circuit 11 to both the first connection portion 21 and the second connection portion 22. This enables the output of the power supply circuit 11 to be supplied from the plurality of (for example, two in this example) connection portions 2 to the USB connector 91 of the device 9.
在这样的配置中，从多个连接部2供给到装置9的电流(和电力)的总和成为单个电源电路11的输出电流。因此，多个连接部2的额定输出(电流或电力)由多个连接部2的输出电流(或输出电力)的总和定义。如本文所使用的，“额定输出”是电流和/或电力的额定值，并且是额定电流和额定电力中的至少一个。也就是说，多个连接部2的组合输出(电流或电力)的额定值由电源电路11的额定输出(电流或电力)确定。例如，如果电源电路11的额定输出为4A，则多个(例如，在该示例中为两个)连接部2的输出电流的总和也具有4A的额定值。In such a configuration, the sum of the current (and power) supplied to the device 9 from the multiple connection parts 2 becomes the output current of a single power supply circuit 11. Therefore, the rated output (current or power) of the multiple connection parts 2 is defined by the sum of the output currents (or output power) of the multiple connection parts 2. As used herein, "rated output" is a rated value of current and/or power, and is at least one of the rated current and the rated power. That is, the rated value of the combined output (current or power) of the multiple connection parts 2 is determined by the rated output (current or power) of the power supply circuit 11. For example, if the rated output of the power supply circuit 11 is 4A, the sum of the output currents of the multiple (for example, two in this example) connection parts 2 also has a rated value of 4A.
在本实施例中，壳体3的正面31如图2的A所示具有分配指示器32，以使得用户能够容易地识别上述额定输出。在本实施例中，分配指示器32例如是压印到壳体3的正面31上的标记。分配指示器32提供输出信息。如本文所使用的，“输出信息”是与可以相对于各个连接部2输出的电力的大小有关的信息。例如，连接部2的额定输出(电流或电力)(即，连接部2的额定电流和额定电力)都与可以从连接部2输出的电力的大小有关，并且被包括在“输出信息”中。注意，在图1中省略了分配指示器32的图示。In the present embodiment, the front side 31 of the housing 3 has an allocation indicator 32 as shown in A of FIG. 2 so that the user can easily identify the above-mentioned rated output. In the present embodiment, the allocation indicator 32 is, for example, a mark imprinted on the front side 31 of the housing 3. The allocation indicator 32 provides output information. As used herein, "output information" is information related to the size of the power that can be output relative to each connection portion 2. For example, the rated output (current or power) of the connection portion 2 (that is, the rated current and rated power of the connection portion 2) are both related to the size of the power that can be output from the connection portion 2 and are included in the "output information". Note that the illustration of the allocation indicator 32 is omitted in FIG. 1.
在本实施例中，如图2的A所示，分配指示器32布置在壳体3的正面31上的连接端口4周围。特别地，在本实施例中，分配指示器32布置在壳体3的正面31上的连接端口4的上方和下方。具体地，由分配指示器32指示的输出信息表示各连接部2的额定输出(额定电流)，诸如“2.5A”或“1.5A”等。在该示例中，针对第一连接部21(第一连接端口41)所设置的分配指示器32将表示其额定输出的输出信息“2.5A”作为字符串(采用文本)来提供。针对第二连接部22(第二连接端口42)所设置的分配指示器32将表示其额定输出的输出信息“1.5A”作为字符串(采用文本)来提供。In the present embodiment, as shown in A of FIG. 2 , the allocation indicator 32 is arranged around the connection port 4 on the front face 31 of the housing 3. In particular, in the present embodiment, the allocation indicator 32 is arranged above and below the connection port 4 on the front face 31 of the housing 3. Specifically, the output information indicated by the allocation indicator 32 represents the rated output (rated current) of each connection portion 2, such as "2.5A" or "1.5A". In this example, the allocation indicator 32 provided for the first connection portion 21 (first connection port 41) provides the output information "2.5A" representing its rated output as a string (in text). The allocation indicator 32 provided for the second connection portion 22 (second connection port 42) provides the output information "1.5A" representing its rated output as a string (in text).
由分配指示器32提供的输出信息还包括指示各个连接部2的优先级的诸如“1”和“2”等的优先级信息。如本文所使用的，“优先级信息”可以是指示优先使用多个连接部2的推荐顺序的任何信息。因此，优先级信息不必是诸如“1”和“2”等的数字，而是也可以是诸如“主”和“副”等的词语。在该示例中，针对第一连接部21(第一连接端口41)所设置的分配指示器32将表示其最高优先级的优先级信息“1”作为字符(采用文本)来提供。针对第二连接部22(第二连接端口42)所设置的分配指示器32将表示其次最高优先级的优先级信息“2”作为字符(采用文本)来提供。在该示例中，推荐相对于第二连接部22优先使用第一连接部21。The output information provided by the allocation indicator 32 also includes priority information such as "1" and "2" indicating the priority of each connection part 2. As used herein, "priority information" can be any information indicating the recommended order of priority use of multiple connection parts 2. Therefore, the priority information does not have to be numbers such as "1" and "2", but can also be words such as "primary" and "secondary". In this example, the allocation indicator 32 set for the first connection part 21 (first connection port 41) provides the priority information "1" indicating its highest priority as a character (in text). The allocation indicator 32 set for the second connection part 22 (second connection port 42) provides the priority information "2" indicating its second highest priority as a character (in text). In this example, it is recommended to use the first connection part 21 in priority to the second connection part 22.
使分配指示器32呈现这样的输出信息推荐了用户优先使用具有最高优先级的第一连接部21。因此，如果仅使用多个(例如，在该示例中为两个)连接部2中的一个，则用户基本上使用第一连接部21。另外，在假定电源电路11的额定输出为4A的情况下，如果仅第一连接部21在其2.5A的额定值内使用，则两个连接部2的输出电流的总和自然在4A的额定输出内。另一方面，在使用第一连接部21和第二连接部22这两者的情况下，如果第一连接部21在其2.5A的额定值内使用并且第二连接部22在其1.5A的额定值内使用，则这两个连接部2的输出电流的总和也将在4A的额定输出内。Making the allocation indicator 32 present such output information recommends that the user preferentially use the first connection portion 21 having the highest priority. Therefore, if only one of the multiple (for example, two in this example) connection portions 2 is used, the user basically uses the first connection portion 21. In addition, assuming that the rated output of the power supply circuit 11 is 4A, if only the first connection portion 21 is used within its rated value of 2.5A, the sum of the output currents of the two connection portions 2 is naturally within the rated output of 4A. On the other hand, in the case of using both the first connection portion 21 and the second connection portion 22, if the first connection portion 21 is used within its rated value of 2.5A and the second connection portion 22 is used within its rated value of 1.5A, the sum of the output currents of the two connection portions 2 will also be within the rated output of 4A.
也就是说，在本实施例中，设置了多个连接部2。壳体3的正面31设置有分配指示器32，该分配指示器32提供指示可以相对于各个连接部2输出的电力的大小的输出信息。另外，输出信息还包括指示多个连接部2的优先级的优先级信息。在存在多个连接部2的情形下使分配指示器32提供这样的输出信息(包括优先级信息)减少了用户对从多个连接部2中选择要使用的连接部2犹豫不决的可能性。That is, in the present embodiment, a plurality of connection parts 2 are provided. The front face 31 of the housing 3 is provided with an allocation indicator 32 which provides output information indicating the magnitude of the power that can be output with respect to each connection part 2. In addition, the output information also includes priority information indicating the priority of the plurality of connection parts 2. Having the allocation indicator 32 provide such output information (including priority information) in the case where there are a plurality of connection parts 2 reduces the possibility that the user will hesitate to select a connection part 2 to be used from the plurality of connection parts 2.
端子部16容纳在壳体3内。在本实施例中，壳体3的背面具有线L1连接到的端子端口。端子部16设置在壳体3内的与端子端口相对应的位置处。端子部16例如包括端子板。在线L1的前端部(芯线)插入端子端口时，端子部16机械地保持线L1的前端部(芯线)并电连接到线L1。在本实施例中，端子部16是所谓的插入型“可快速连接的端子”，其中仅仅通过经由端子端口插入线L1使线L1连接到端子部16。The terminal portion 16 is accommodated in the housing 3. In the present embodiment, the back side of the housing 3 has a terminal port to which the wire L1 is connected. The terminal portion 16 is arranged at a position in the housing 3 corresponding to the terminal port. The terminal portion 16 includes, for example, a terminal plate. When the front end portion (core wire) of the wire L1 is inserted into the terminal port, the terminal portion 16 mechanically holds the front end portion (core wire) of the wire L1 and is electrically connected to the wire L1. In the present embodiment, the terminal portion 16 is a so-called plug-in type “quickly connectable terminal”, in which the wire L1 is connected to the terminal portion 16 simply by inserting the wire L1 through the terminal port.
控制单元101包括包含一个或多于一个处理器和一个或多于一个存储器的微控制器作为主要构成元件。微控制器通过使一个或多于一个处理器执行一个或多于一个存储器中所存储的程序来进行控制单元101的功能。程序可以预先存储在存储器中。可替代地，程序也可以在存储在诸如存储卡等的非暂时性存储介质中之后进行分发或者经由远程通信线路下载。换句话说，程序被设计为使得一个或多于一个处理器用作控制单元101。The control unit 101 includes a microcontroller including one or more processors and one or more memories as a main component. The microcontroller performs the functions of the control unit 101 by causing one or more processors to execute programs stored in one or more memories. The program can be pre-stored in the memory. Alternatively, the program can also be distributed or downloaded via a remote communication line after being stored in a non-transitory storage medium such as a memory card. In other words, the program is designed so that one or more processors are used as the control unit 101.
控制单元101至少控制电源电路11。另外，在本实施例中，如上所述，控制单元101安装在电源电路11的电路板上，并且连同电源电路11一起容纳在壳体3中。此外，如图4所示，控制单元101还可以用作检测单元12和设置单元13。检测单元12不断地将监视值与阈值进行比较以检测到监视值大于阈值。如上所述，监视值是以下项中的至少一个：要供给到装置9的电流的大小、要供给到装置9的电流的累计值、要供给到装置9的电力的大小、要供给到装置9的电能、以及向装置9供给电力的时间长度。例如，设置单元13进行与检测单元12的操作有关的各种设置。后面将在“(2.4)警报功能”部分中详细说明检测单元12和设置单元13的功能。The control unit 101 controls at least the power supply circuit 11. In addition, in the present embodiment, as described above, the control unit 101 is mounted on a circuit board of the power supply circuit 11 and is contained in the housing 3 together with the power supply circuit 11. In addition, as shown in FIG4 , the control unit 101 can also be used as a detection unit 12 and a setting unit 13. The detection unit 12 continuously compares the monitoring value with a threshold value to detect that the monitoring value is greater than the threshold value. As described above, the monitoring value is at least one of the following items: the magnitude of the current to be supplied to the device 9, the cumulative value of the current to be supplied to the device 9, the magnitude of the power to be supplied to the device 9, the electric energy to be supplied to the device 9, and the length of time for supplying power to the device 9. For example, the setting unit 13 performs various settings related to the operation of the detection unit 12. The functions of the detection unit 12 and the setting unit 13 will be described in detail later in the "(2.4) Alarm function" section.
警报单元102发出指示检测单元12的检测结果的警报。在本实施例中，警报单元102包括显示单元14和声音发出单元15。显示单元14设置在壳体3的正面上。警报单元102通过显示单元14的显示模式来发出警报。在本实施例中，如图2的B所示，显示单元14各自包括发光元件141和光学构件142。这种类型的显示单元14的显示模式的示例包括点亮/熄灭状态、所发出的光的颜色、点亮图案(闪烁周期)、以及其组合。简言之，在本实施例中，警报单元102包括设置在壳体3的正面31上的显示单元14。警报单元102通过显示单元14的显示模式来发出警报(其指示检测单元12的检测结果)。The alarm unit 102 issues an alarm indicating the detection result of the detection unit 12. In the present embodiment, the alarm unit 102 includes a display unit 14 and a sound emitting unit 15. The display unit 14 is arranged on the front side of the housing 3. The alarm unit 102 issues an alarm through the display mode of the display unit 14. In the present embodiment, as shown in B of FIG. 2 , the display units 14 each include a light emitting element 141 and an optical member 142. Examples of display modes of this type of display unit 14 include a light-on/off state, a color of the light emitted, a light-on pattern (flash cycle), and a combination thereof. In short, in the present embodiment, the alarm unit 102 includes a display unit 14 arranged on the front side 31 of the housing 3. The alarm unit 102 issues an alarm (which indicates the detection result of the detection unit 12) through the display mode of the display unit 14.
在本实施例中，如图2的A和图2的B所示，显示单元14布置在壳体3的正面31上的连接端口4周围。在本实施例中，显示单元14各自被布置成在壳体3的正面31上沿着其整个周边包围关联的连接端口4。因此，显示单元14从连接端口4的整个周边发光。换句话说，各连接端口4位于在壳体3的正面31上被关联的环状显示单元14包围的区域中。In the present embodiment, as shown in FIG. 2A and FIG. 2B , the display units 14 are arranged around the connection ports 4 on the front face 31 of the housing 3. In the present embodiment, the display units 14 are each arranged to surround the associated connection port 4 along its entire periphery on the front face 31 of the housing 3. Therefore, the display units 14 emit light from the entire periphery of the connection port 4. In other words, each connection port 4 is located in an area surrounded by the associated annular display unit 14 on the front face 31 of the housing 3.
具体地，发光元件141例如在接收到从控制单元101供给的电力时发光。发光元件141例如可以被实现为发光二极管(LED)。光学构件142例如可以是诸如丙烯酸树脂等的透明树脂的模制品，并且是接收从发光元件141发出的光并将自身内部的光引导到其表面(正面)的构件。也就是说，光学构件142是光导构件。光学构件142在前视图中是以矩形框的形状形成的，并且光学构件142的框的内部是连接端口4。在具有这种结构的各个显示单元14中，在发光元件141发光时，光学构件142的表面(正面)也从其发光。也就是说，包围连接端口4的光学构件142的表面(正面)是发光面。Specifically, the light emitting element 141 emits light, for example, when receiving power supplied from the control unit 101. The light emitting element 141 can be implemented as a light emitting diode (LED), for example. The optical member 142 can be, for example, a molded product of a transparent resin such as an acrylic resin, and is a member that receives light emitted from the light emitting element 141 and guides the light inside itself to its surface (front). That is, the optical member 142 is a light-guiding member. The optical member 142 is formed in the shape of a rectangular frame in the front view, and the inside of the frame of the optical member 142 is the connection port 4. In each display unit 14 having such a structure, when the light emitting element 141 emits light, the surface (front) of the optical member 142 also emits light therefrom. That is, the surface (front) of the optical member 142 surrounding the connection port 4 is a light emitting surface.
此外，在本实施例中，显示单元14被配置为即使在装置9的USB连接器91连接到关联的连接部2(连接端口4)的状态下，也从前方可见。具体地，显示单元14被配置为在前视图中至少部分地突出到USB连接器91周围的区域中。换句话说，即使显示单元14设置在连接端口4周围，显示单元14也不会完全隐藏在插入到连接端口4中的USB连接器91的后方。这使得即使在装置9的USB连接器91连接到USB插座10的状态下也能够用眼睛检查显示单元14的显示模式。Furthermore, in the present embodiment, the display unit 14 is configured to be visible from the front even in a state where the USB connector 91 of the device 9 is connected to the associated connection portion 2 (connection port 4). Specifically, the display unit 14 is configured to at least partially protrude into the area around the USB connector 91 in a front view. In other words, even if the display unit 14 is provided around the connection port 4, the display unit 14 is not completely hidden behind the USB connector 91 inserted into the connection port 4. This makes it possible to visually check the display mode of the display unit 14 even in a state where the USB connector 91 of the device 9 is connected to the USB socket 10.
声音发出单元15例如可以被实现为扬声器或蜂鸣器。声音发出单元15例如可以发出哔哔声，并且通过从自身发出的哔哔声的声音模式来发出指示检测单元12的检测结果的警报。哔哔声的声音模式的示例包括“嘟”、“嘟嘟”和“哔哔”。然而，声音发出单元15不必发出哔哔声，而是除了哔哔声之外或代替哔哔声，还可以发出语音或旋律。The sound emitting unit 15 may be implemented as a speaker or a buzzer, for example. The sound emitting unit 15 may emit a beeping sound, for example, and issue an alarm indicating the detection result of the detection unit 12 by a sound pattern of the beeping sound emitted from itself. Examples of the sound pattern of the beeping sound include "beep", "beep beep", and "beep beep". However, the sound emitting unit 15 does not have to emit a beeping sound, but may emit a voice or a melody in addition to or instead of the beeping sound.
另外，在本实施例中，如上所述，设置了多个连接部2。因此，警报单元102被配置为针对多个连接部2中的各连接部单独地发出指示检测结果的警报。具体地，如图2的A和图2的B所示，显示单元14是针对至少各连接端口4所设置的。换句话说，分别针对多个连接端口4设置多个显示单元14。多个显示单元14分别设置在第一连接端口41和第二连接端口42周围。尽管在图4中示出仅一个显示单元14，但实际上设置了多个(例如，在该示例中为两个)显示单元14。以下将在“(2.4)警报功能”部分中详细说明警报单元102的功能。In addition, in the present embodiment, as described above, a plurality of connection parts 2 are provided. Therefore, the alarm unit 102 is configured to individually issue an alarm indicating a detection result for each of the plurality of connection parts 2. Specifically, as shown in A of FIG. 2 and B of FIG. 2 , the display unit 14 is provided for at least each connection port 4. In other words, a plurality of display units 14 are provided for the plurality of connection ports 4, respectively. The plurality of display units 14 are provided around the first connection port 41 and the second connection port 42, respectively. Although only one display unit 14 is shown in FIG. 4 , a plurality of (for example, two in this example) display units 14 are actually provided. The function of the alarm unit 102 will be described in detail in the “(2.4) Alarm function” section below.
(2.4)警报功能(2.4) Alarm function
接着，将说明根据本实施例的USB插座10的警报功能。警报功能主要由包括在控制单元101中的检测单元12和设置单元13以及由警报单元102进行。Next, the alarm function of the USB socket 10 according to the present embodiment will be described. The alarm function is mainly performed by the detection unit 12 and the setting unit 13 included in the control unit 101 and by the alarm unit 102.
如上所述，检测单元12不断地将监视值与阈值进行比较，以检测到监视值大于阈值(下文中称为“监视值的异常”)。如本文所使用的，“监视值”是以下项中的至少一个：要供给到装置9的电流的大小、要供给到装置9的电流的累计值、要供给到装置9的电力的大小、要供给到装置9的电能、以及向装置9供给电力的时间长度。如本文所使用的，向装置9供给电力的时间长度意味着在已从USB插座10(电源电路11)向装置9连续地供给电力的情形下的自开始供给电力的时间点起所经过的时间长度。也就是说，检测单元12将例如要从USB插座10(电源电路11)供给到装置9的电流的大小视为监视值，并且将该监视值与阈值进行比较。阈值是针对监视值的各类型设置的。阈值的示例包括电流的大小的阈值和电流的累计值的阈值。As described above, the detection unit 12 constantly compares the monitoring value with the threshold value to detect that the monitoring value is greater than the threshold value (hereinafter referred to as "abnormality of the monitoring value"). As used herein, the "monitoring value" is at least one of the following items: the magnitude of the current to be supplied to the device 9, the cumulative value of the current to be supplied to the device 9, the magnitude of the power to be supplied to the device 9, the electric energy to be supplied to the device 9, and the length of time for supplying power to the device 9. As used herein, the length of time for supplying power to the device 9 means the length of time that has passed since the time point when power supply starts in the case where power has been continuously supplied to the device 9 from the USB socket 10 (power circuit 11). That is, the detection unit 12 regards, for example, the magnitude of the current to be supplied to the device 9 from the USB socket 10 (power circuit 11) as a monitoring value, and compares the monitoring value with the threshold value. The threshold value is set for each type of monitoring value. Examples of the threshold value include a threshold value for the magnitude of the current and a threshold value for the cumulative value of the current.
可以基于电源电路11的输出电流或电力的大小来检测供给到装置9的电流或电力的大小。因此，检测单元12监视(测量)电源电路11的输出电流或电力，并且基于该电流或电力的大小检测到监视值大于阈值(即，检测监视值的异常)。可以利用诸如电流变压器或分流电阻器等的适当的电流传感器来测量电源电路11的输出电流。要供给到装置9的电流的累计值、要供给到装置9的电能以及向装置9供给电力的时间长度各自可以基于电源电路11的输出电流或电力的大小来获得。The magnitude of the current or power supplied to the device 9 can be detected based on the magnitude of the output current or power of the power supply circuit 11. Therefore, the detection unit 12 monitors (measures) the output current or power of the power supply circuit 11, and detects that the monitoring value is greater than a threshold value based on the magnitude of the current or power (i.e., detects an abnormality in the monitoring value). The output current of the power supply circuit 11 can be measured using an appropriate current sensor such as a current transformer or a shunt resistor. The accumulated value of the current to be supplied to the device 9, the electric energy to be supplied to the device 9, and the length of time for which power is supplied to the device 9 can each be obtained based on the magnitude of the output current or power of the power supply circuit 11.
另外，要与阈值进行比较的监视值是以下项中的至少一个：要供给到装置9的电流的大小、要供给到装置9的电流的累计值、要供给到装置9的电力的大小、要供给到装置9的电能、以及向装置9供给电力的时间长度。也就是说，监视值例如可以是要供给到装置9的电流的大小或向装置9供给电力的时间长度、或者它们的组合。在本实施例中，例如，假定监视值是要从USB插座10(电源电路11)供给到装置9的电流的大小。也就是说，检测单元12将要从USB插座10(电源电路11)供给到装置9的电流的大小视为示例性监视值，并且将该监视值与阈值进行比较。In addition, the monitoring value to be compared with the threshold value is at least one of the magnitude of the current to be supplied to the device 9, the cumulative value of the current to be supplied to the device 9, the magnitude of the power to be supplied to the device 9, the electric energy to be supplied to the device 9, and the length of time for which the power is supplied to the device 9. That is, the monitoring value may be, for example, the magnitude of the current to be supplied to the device 9 or the length of time for which the power is supplied to the device 9, or a combination thereof. In the present embodiment, for example, it is assumed that the monitoring value is the magnitude of the current to be supplied from the USB socket 10 (power supply circuit 11) to the device 9. That is, the detection unit 12 regards the magnitude of the current to be supplied from the USB socket 10 (power supply circuit 11) to the device 9 as an exemplary monitoring value, and compares the monitoring value with the threshold value.
设置单元13进行与检测单元12的操作有关的各种设置。例如，设置单元13可以进行设置，以判断将要供给到装置9的电流的大小、要供给到装置9的电流的累计值和要供给到装置9的电力的大小中的哪个视为监视值。此外，设置单元13还进行与例如要与监视值进行比较的阈值有关的设置。此外，设置单元13适当地进行与警报单元102的操作有关的各种设置。在本实施例中，由设置单元13进行的设置的细节是根据人对壳体3内部所设置的诸如DIP开关或半固定电阻器等的操作构件进行的操作来确定的。The setting unit 13 performs various settings related to the operation of the detection unit 12. For example, the setting unit 13 can perform settings to determine which of the magnitude of the current to be supplied to the device 9, the integrated value of the current to be supplied to the device 9, and the magnitude of the power to be supplied to the device 9 is regarded as the monitoring value. In addition, the setting unit 13 also performs settings related to, for example, a threshold value to be compared with the monitoring value. In addition, the setting unit 13 appropriately performs various settings related to the operation of the alarm unit 102. In the present embodiment, the details of the settings performed by the setting unit 13 are determined according to the operation performed by a person on an operating member such as a DIP switch or a semi-fixed resistor provided inside the housing 3.
另外，警报单元102向用户警报检测单元12的检测结果。在本实施例中，警报单元102如上所述包括显示单元14和声音发出单元15，并且通过显示单元14上的显示模式或从声音发出单元15发出的声音的模式来向用户警报检测单元12的检测结果。例如，在监视值是要从USB插座10(电源电路11)供给到装置9的电流的大小的情形下，警报单元102根据电流(监视值)的大小是等于或小于还是大于阈值而以不同的方式发出警报。In addition, the alarm unit 102 alerts the user of the detection result of the detection unit 12. In the present embodiment, the alarm unit 102 includes the display unit 14 and the sound emitting unit 15 as described above, and alerts the user of the detection result of the detection unit 12 through a display pattern on the display unit 14 or a pattern of sound emitted from the sound emitting unit 15. For example, in a case where the monitored value is the magnitude of the current to be supplied from the USB socket 10 (power supply circuit 11) to the device 9, the alarm unit 102 issues an alarm in a different manner depending on whether the magnitude of the current (monitored value) is equal to, less than, or greater than a threshold value.
例如，如果监视值(例如，在该示例中为电流的大小)等于或小于阈值，则警报单元102使显示单元14中的至少一个以绿色点亮。另一方面，如果监视值(例如，在该示例中为电流的大小)大于(即，超过)阈值，则警报单元102使显示单元14中的至少一个以红色点亮。因此，(一个或多于一个)显示单元14在不存在监视值的异常的情况下将以绿色点亮，并且在存在监视值的任何异常的情况下将以红色点亮。此外，除非装置9的USB连接器91连接到任何连接部2，否则警报单元102可以使显示单元14保持熄灭。此外，如果监视值(例如，在该示例中为电流的大小)大于阈值，则警报单元102可以从声音发出单元15发出诸如“哔哔”等的哔哔声。在监视值大于阈值期间，适当地连续发出哔哔声。For example, if the monitoring value (e.g., the magnitude of the current in this example) is equal to or less than the threshold value, the alarm unit 102 lights up at least one of the display units 14 in green. On the other hand, if the monitoring value (e.g., the magnitude of the current in this example) is greater than (i.e., exceeds) the threshold value, the alarm unit 102 lights up at least one of the display units 14 in red. Therefore, (one or more than one) display unit 14 will light up in green in the absence of an abnormality in the monitoring value, and will light up in red in the presence of any abnormality in the monitoring value. In addition, the alarm unit 102 may keep the display unit 14 off unless the USB connector 91 of the device 9 is connected to any connection portion 2. In addition, if the monitoring value (e.g., the magnitude of the current in this example) is greater than the threshold value, the alarm unit 102 may emit a beep sound such as "beep" from the sound emitting unit 15. During the period when the monitoring value is greater than the threshold value, the beep sound is appropriately continuously emitted.
另外，在本实施例中，如上所述设置了多个连接部2。因此，检测单元12针对多个连接部2中的各连接部单独地检测监视值的异常(即，监视值大于阈值)。例如，如果监视值是要从USB插座10(电源电路11)供给到装置9的电流的大小，则检测单元12检测到以下作为监视值的异常：针对第一连接部21和第二连接部22各自，电流(其是示例性监视值)的大小大于阈值。因此，检测单元12检测到第一连接部21和第二连接部22的各个监视值都异常的状态、第一连接部21的监视值和第二连接部22的监视值都不异常的状态、仅第一连接部21的监视值异常的状态、或者仅第二连接部22的监视值异常的状态。为了针对各个连接部2单独地检测监视值的异常，检测单元12可以彼此可区分地监视(测量)例如从电源电路11供给到第一连接部21的电流和从电源电路11供给到第二连接部22的电流。In addition, in the present embodiment, a plurality of connection parts 2 are provided as described above. Therefore, the detection unit 12 detects the abnormality of the monitoring value (i.e., the monitoring value is greater than the threshold value) for each of the plurality of connection parts 2 individually. For example, if the monitoring value is the magnitude of the current to be supplied from the USB socket 10 (power circuit 11) to the device 9, the detection unit 12 detects the following as the abnormality of the monitoring value: for each of the first connection part 21 and the second connection part 22, the magnitude of the current (which is an exemplary monitoring value) is greater than the threshold value. Therefore, the detection unit 12 detects a state in which each of the monitoring values of the first connection part 21 and the second connection part 22 is abnormal, a state in which neither the monitoring value of the first connection part 21 nor the monitoring value of the second connection part 22 is abnormal, a state in which only the monitoring value of the first connection part 21 is abnormal, or a state in which only the monitoring value of the second connection part 22 is abnormal. In order to detect the abnormality of the monitoring value individually for each of the connection parts 2, the detection unit 12 can monitor (measure) the current supplied from the power circuit 11 to the first connection part 21 and the current supplied from the power circuit 11 to the second connection part 22, for example, distinguishably from each other.
另外，在本实施例中，警报单元102还针对各个连接部2单独地对(如由检测单元12的检测结果所示的)监视值的异常发出警报。例如，如果监视值是要从USB插座10(电源电路11)供给到装置9的电流的大小，则警报单元102发出以下警报作为监视值的异常：针对第一连接部21和第二连接部22各自，(作为示例性监视值的)电流的大小大于阈值。例如，如果仅第一连接部21具有异常监视值，则警报单元102使与第一连接部21相关联的显示单元14以红色点亮，并且使与第二连接部22相关联的显示单元14以绿色点亮。警报单元102通过使以下状态彼此区分开来对这些状态发出警报：第一连接部21和第二连接部22的各个监视值都异常的状态、第一连接部21的监视值和第二连接部22的监视值都不异常的状态、仅第一连接部21的监视值异常的状态、以及仅第二连接部22的监视值异常的状态。In addition, in the present embodiment, the alarm unit 102 also issues an alarm for the abnormality of the monitoring value (as indicated by the detection result of the detection unit 12) for each connection part 2 individually. For example, if the monitoring value is the magnitude of the current to be supplied from the USB socket 10 (power supply circuit 11) to the device 9, the alarm unit 102 issues the following alarm as the abnormality of the monitoring value: for each of the first connection part 21 and the second connection part 22, the magnitude of the current (as an exemplary monitoring value) is greater than the threshold value. For example, if only the first connection part 21 has an abnormal monitoring value, the alarm unit 102 lights up the display unit 14 associated with the first connection part 21 in red, and lights up the display unit 14 associated with the second connection part 22 in green. The alarm unit 102 issues an alarm for the following states by distinguishing the following states from each other: a state in which each of the monitoring values of the first connection part 21 and the second connection part 22 is abnormal, a state in which neither the monitoring value of the first connection part 21 nor the monitoring value of the second connection part 22 is abnormal, a state in which only the monitoring value of the first connection part 21 is abnormal, and a state in which only the monitoring value of the second connection part 22 is abnormal.
(3)操作(3) Operation
接着，将参考图5来说明根据本实施例的USB插座10如何操作。图5是示出在监视值是从USB插座10(电源电路11)供给到装置9的电流的大小的情形下的USB插座10的示例性操作的流程图。Next, how the USB socket 10 according to the present embodiment operates will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an exemplary operation of the USB socket 10 in a case where the monitoring value is the magnitude of the current supplied to the device 9 from the USB socket 10 (power supply circuit 11).
在已启动之后，首先，USB插座10发出指示监视值正常(即，监视值无异常)的警报(在S1中)。在这种情况下，警报单元102可以使显示单元14以绿色点亮。之后，USB插座10使检测单元12判断监视值(例如，电流的大小)是否大于阈值(在S2中)。如果检测单元12未检测到监视值的异常(即，检测到监视值不大于阈值)(如果在S2中回答为“否”)，则USB插座10继续发出指示监视值正常的警报(在S1中)。After being started, first, the USB socket 10 issues an alarm indicating that the monitoring value is normal (i.e., the monitoring value has no abnormality) (in S1). In this case, the alarm unit 102 can light up the display unit 14 in green. Thereafter, the USB socket 10 causes the detection unit 12 to determine whether the monitoring value (e.g., the magnitude of the current) is greater than a threshold value (in S2). If the detection unit 12 does not detect an abnormality in the monitoring value (i.e., detects that the monitoring value is not greater than the threshold value) (if the answer in S2 is "No"), the USB socket 10 continues to issue an alarm indicating that the monitoring value is normal (in S1).
另一方面，如果检测单元12检测到监视值的异常(即，检测到监视值大于阈值)(如果在S2中回答为“是”)，则USB插座10使警报单元102发出指示监视值异常的警报(在S3中)。在这种情况下，警报单元102可以使显示单元14以红色点亮。之后，USB插座10使检测单元12判断监视值(例如，电流的大小)是否等于或小于阈值(在S4中)。如果监视值正常(即，除非检测单元12检测到监视值等于或小于阈值)(如果在S4中回答为“否”)，则USB插座10继续发出指示监视值异常的警报(在S3中)。On the other hand, if the detection unit 12 detects an abnormality in the monitoring value (i.e., detects that the monitoring value is greater than the threshold value) (if the answer is "yes" in S2), the USB socket 10 causes the alarm unit 102 to issue an alarm indicating that the monitoring value is abnormal (in S3). In this case, the alarm unit 102 can light up the display unit 14 in red. Thereafter, the USB socket 10 causes the detection unit 12 to determine whether the monitoring value (e.g., the magnitude of the current) is equal to or less than the threshold value (in S4). If the monitoring value is normal (i.e., unless the detection unit 12 detects that the monitoring value is equal to or less than the threshold value) (if the answer is "no" in S4), the USB socket 10 continues to issue an alarm indicating that the monitoring value is abnormal (in S3).
如果检测单元12检测到监视值正常(即，监视值等于或小于阈值)(如果在S4中回答为“是”)，则USB插座10使警报单元102发出指示监视值正常(即，监视值无异常)的警报(在S1中)。If the detection unit 12 detects that the monitoring value is normal (i.e., the monitoring value is equal to or less than the threshold) (if the answer is "Yes" in S4), the USB socket 10 causes the alarm unit 102 to issue an alarm indicating that the monitoring value is normal (i.e., the monitoring value has no abnormality) (in S1).
USB插座10反复地进行这一系列处理步骤S1-S4。注意，图5的流程图仅示出USB插座10的示例性操作。因此，可以省略这些处理步骤中的至少一个，或者可以适当地向这些处理步骤添加至少又一个处理步骤，或者可以适当地改变进行这些处理步骤的顺序。The USB socket 10 repeatedly performs this series of processing steps S1-S4. Note that the flowchart of FIG5 shows only an exemplary operation of the USB socket 10. Therefore, at least one of these processing steps may be omitted, or at least one more processing step may be appropriately added to these processing steps, or the order in which these processing steps are performed may be appropriately changed.
从上述说明可以看出，在根据本实施例的USB插座10中，当诸如要从电源电路11供给到装置9的电流的大小等的监视值变得大于阈值时，警报单元102发出警报。因此，如果例如将比电源电路11的额定输出(电流或电力)大的过大电流或电力从USB插座10供给到装置9，则可以向用户警报异常。特别地，在USB插座10中，不同于输出100V或200V的AC电压的一般AC插座，即使过大电流流经装置9，其配电盘的断路器有时也不会立即中断。因此，发出这样的警报是有用的。这使得能够对监视值(诸如要供给到装置9的电流的大小等)的异常发出早期警报，由此有助于提高USB插座10的可靠性。因此，可以提供更有效地有助于提高可靠性的USB插座10。As can be seen from the above description, in the USB socket 10 according to the present embodiment, when a monitoring value such as the magnitude of the current to be supplied from the power circuit 11 to the device 9 becomes greater than a threshold value, the alarm unit 102 issues an alarm. Therefore, if, for example, an excessive current or power greater than the rated output (current or power) of the power circuit 11 is supplied from the USB socket 10 to the device 9, the user can be alerted of the abnormality. In particular, in the USB socket 10, unlike a general AC socket that outputs an AC voltage of 100V or 200V, even if an excessive current flows through the device 9, the circuit breaker of its distribution board sometimes does not immediately interrupt. Therefore, it is useful to issue such an alarm. This enables an early alarm to be issued for an abnormality of a monitoring value such as the magnitude of the current to be supplied to the device 9, thereby contributing to improving the reliability of the USB socket 10. Therefore, a USB socket 10 that more effectively contributes to improving reliability can be provided.
此外，例如，不是待充电的装置9而是充电侧的装置(即，供给充电所用的电力的USB插座10)对过大电流发出警报。例如，这使得不再需要为了对过大电流发出警报的目的而消耗待充电的装置9的电力。也就是说，待充电的装置9可以使用已存储或将存储在蓄电池92中的电力，以例如进行作为最初预期用途的充电、而不是用于对过大电流发出警报的目的。因此，根据本实施例的USB插座10实现了能够高效地对装置9充电的优点。Furthermore, for example, it is not the device 9 to be charged but the device on the charging side (i.e., the USB socket 10 that supplies the power for charging) that issues an alarm for an excessive current. For example, this makes it unnecessary to consume the power of the device 9 to be charged for the purpose of issuing an alarm for an excessive current. That is, the device 9 to be charged can use the power that has been stored or will be stored in the storage battery 92, for example, for charging as the originally intended use, rather than for the purpose of issuing an alarm for an excessive current. Therefore, the USB socket 10 according to the present embodiment achieves the advantage of being able to efficiently charge the device 9.

注意，上述的第一实施例仅是本发明的各种实施例中的示例性实施例，并且不应被解释为限制性的。相反，可以在未背离本发明的范围的情况下，根据设计选择或任何其他因素以各种方式容易地修改第一实施例。在实施例的以下说明中要参考的图全部是示意图。也就是说，这些图上例示的各个构成元件的尺寸(包括厚度)的比并不总是反映这些构成元件的实际尺寸比。此外，根据第一实施例的USB插座10的功能也可以被实现为例如方法、(计算机)程序或存储有该程序的非暂时性存储介质。Note that the first embodiment described above is only an exemplary embodiment of the various embodiments of the present invention, and should not be interpreted as restrictive. On the contrary, the first embodiment can be easily modified in various ways according to design selection or any other factors without departing from the scope of the present invention. The figures to be referred to in the following description of the embodiment are all schematic diagrams. That is to say, the ratio of the size (including thickness) of each constituent element illustrated in these figures does not always reflect the actual size ratio of these constituent elements. In addition, the function of the USB socket 10 according to the first embodiment can also be implemented as, for example, a method, a (computer) program, or a non-temporary storage medium storing the program.
接着，将逐个列举第一实施例的变形例。注意，可以适当地组合采用以下要说明的变形例。在以下的说明中，具有与上述第一实施例的对应物相同的功能的任何构成元件将由与该对应物的附图标记相同的附图标记指定，并且这里将适当地省略其说明。Next, the modified examples of the first embodiment will be listed one by one. Note that the modified examples to be described below can be appropriately combined and adopted. In the following description, any constituent element having the same function as the counterpart of the above-mentioned first embodiment will be designated by the same reference numeral as the reference numeral of the counterpart, and its description will be appropriately omitted here.
USB插座10的基本结构不必如针对第一实施例所述。可替代地，可以如图6的A至图6的C所示设置具有各种实现的USB插座10A-10C。The basic structure of the USB socket 10 is not necessarily as described for the first embodiment. Alternatively, USB sockets 10A-10C having various implementations may be provided as shown in FIGS. 6A to 6C.
在具有图6的A所示的实现的USB插座10A中，显示单元14是以与第一实施例不同的方式配置的，并且各自被放置在包围关联的连接端口4的区域中的单个部位，而不具有如包围关联的连接端口4那样的形状。具体地，在图6的A所示的示例中，各个显示单元14被实现为放置在关联的连接端口4上方的点光源。In the USB outlet 10A having the implementation shown in A of FIG. 6 , the display units 14 are configured in a manner different from the first embodiment, and are each placed at a single location in a region surrounding the associated connection port 4, without having a shape such as to surround the associated connection port 4. Specifically, in the example shown in A of FIG. 6 , each display unit 14 is implemented as a point light source placed above the associated connection port 4.
在具有图6的B所示的实现的USB插座10B中，其壳体3被形成为具有与具有双端口模组尺寸的布线装置大致相同的尺寸。该USB插座10B可以连同被配置为输出100V的AC电压的插座装置51一起例如利用安装支架84(参见图3的A)安装到对象结构物81(参见图3的A)上。In the USB socket 10B having the implementation shown in B of Fig. 6, its housing 3 is formed to have substantially the same size as a wiring device having the size of a dual-port module. This USB socket 10B can be mounted on a target structure 81 (see A of Fig. 3) together with a socket device 51 configured to output an AC voltage of 100V, for example, using a mounting bracket 84 (see A of Fig. 3).
在具有图6的C所示实现的USB插座10C中，其壳体3具有与具有双端口模组尺寸的布线装置大致相同的尺寸。图6的C所示的USB插座10C是单个USB连接器91可以连接到的单端口USB插座。在图6的C所示的示例中，连接端口4具有矩形的形状，其中在前视图中该矩形在上/下方向上的尺寸大于其在右/左方向上的尺寸。也就是说，连接端口4是垂直地布置的(即，被布置成垂直伸长)。此外，该USB插座10C连同诸如人体检测传感器等的传感器装置52一起利用安装支架84(参见图3的A)安装到对象结构物81(参见图3的A)上。传感器装置52不必是人体检测传感器，而是还可以是亮度传感器、振动传感器、接近传感器或声音传感器或其组合。USB插座10C可以基于传感器装置52的输出来操作。例如，如果传感器装置52是人体检测传感器，则当在传感器装置52周围没有人时，USB插座10C切断供给到连接部2的电流。In the USB socket 10C having the implementation shown in C of FIG. 6, its housing 3 has approximately the same size as a wiring device having the size of a dual-port module. The USB socket 10C shown in C of FIG. 6 is a single-port USB socket to which a single USB connector 91 can be connected. In the example shown in C of FIG. 6, the connection port 4 has a rectangular shape, wherein the size of the rectangle in the upper/lower direction is greater than its size in the right/left direction in the front view. That is, the connection port 4 is arranged vertically (i.e., arranged to be vertically elongated). In addition, the USB socket 10C is mounted to the object structure 81 (see A of FIG. 3) together with a sensor device 52 such as a human detection sensor using a mounting bracket 84 (see A of FIG. 3). The sensor device 52 does not have to be a human detection sensor, but may also be a brightness sensor, a vibration sensor, a proximity sensor, or a sound sensor or a combination thereof. The USB socket 10C can operate based on the output of the sensor device 52. For example, if the sensor device 52 is a human detection sensor, when there is no one around the sensor device 52, the USB socket 10C cuts off the current supplied to the connection portion 2.
可选地，USB插座可以具有仅一个连接部2(连接端口4)或者三个或多于三个连接部2(连接端口4)。Alternatively, the USB socket may have only one connection portion 2 (connection port 4 ) or three or more connection portions 2 (connection ports 4 ).
此外，多个连接部2可以包括属于相互不同的代(符合相互不同的传输速率标准)和/或具有相互不同的USB端子形状的两个或多于两个连接部2。例如，USB插座10可以包括与USB Type-A端子兼容的连接部2和与USB Type-C端子兼容的连接部2。In addition, the plurality of connection parts 2 may include two or more connection parts 2 that belong to different generations (comply with different transmission rate standards) and/or have different USB terminal shapes. For example, the USB socket 10 may include a connection part 2 compatible with a USB Type-A terminal and a connection part 2 compatible with a USB Type-C terminal.
根据本发明的USB插座10例如在其控制单元101中包括计算机系统。计算机系统可以包括处理器和存储器作为主要硬件组件。可以通过使处理器执行计算机系统的存储器中所存储的程序来进行根据本发明的USB插座10的功能。程序可以预先存储在计算机系统的存储器中。可替代地，程序也可以通过远程通信线路下载，或者在记录在诸如存储卡、光盘或硬盘驱动器(其中的任何对于计算机系统均是可读的)等的一些非暂时性存储介质中之后进行分发。计算机系统的处理器可以由包括半导体集成电路(IC)或大规模集成电路(LSI)的单个或多个电子电路构成。如本文所使用的，诸如IC或LSI等的“集成电路”根据其集成的程度而被称为不同的名称。集成电路的示例包括系统LSI、超大规模集成电路(VLSI)和特大规模集成电路(ULSI)。可选地，还可以采用在制造了LSI之后要编程的现场可编程门阵列(FPGA)或者允许重新配置LSI内部的连接或电路区段的重新配置的逻辑器件作为处理器。这些电子电路可以一起集成在单个芯片上或分布在多个芯片上，无论哪种都是适当的。这些多个芯片可以一起集成在单个装置中或者分布在多个装置中，而没有限制。如本文所使用的，“计算机系统”包括包含一个或多于一个处理器和一个或多于一个存储器的微控制器。因此，微控制器也可以被实现为包括半导体集成电路或大规模集成电路的单个或多个电子电路。The USB socket 10 according to the present invention includes a computer system, for example, in its control unit 101. The computer system may include a processor and a memory as main hardware components. The functions of the USB socket 10 according to the present invention may be performed by causing the processor to execute a program stored in the memory of the computer system. The program may be pre-stored in the memory of the computer system. Alternatively, the program may also be downloaded via a remote communication line, or distributed after being recorded in some non-temporary storage media such as a memory card, an optical disk, or a hard disk drive (any of which is readable by the computer system). The processor of the computer system may be composed of a single or multiple electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). As used herein, "integrated circuits" such as IC or LSI are referred to by different names according to the degree of their integration. Examples of integrated circuits include system LSI, very large-scale integrated circuits (VLSI) and ultra-large-scale integrated circuits (ULSI). Alternatively, a field programmable gate array (FPGA) to be programmed after the LSI is manufactured or a logic device that allows the reconfiguration of the connection or circuit section inside the LSI to be reconfigured may also be used as a processor. These electronic circuits may be integrated together on a single chip or distributed on multiple chips, whichever is appropriate. These multiple chips can be integrated together in a single device or distributed in multiple devices without limitation. As used herein, a "computer system" includes a microcontroller comprising one or more processors and one or more memories. Therefore, a microcontroller can also be implemented as a single or multiple electronic circuits including semiconductor integrated circuits or large-scale integrated circuits.
此外，在上述实施例中，USB插座的至少一些功能一起集成在单个壳体3中。然而，这仅是示例，并且不应被解释为限制性的。可替代地，USB插座10的这些构成元件可以分布在多个不同的壳体中。例如，控制单元101的一些功能可以是针对与连接部2(连接端口4)的壳体不同的壳体所设置的。还可替代地，控制单元101的至少一些功能例如也可以被实现为服务器或云计算系统。In addition, in the above-described embodiment, at least some functions of the USB socket are integrated together in a single housing 3. However, this is only an example and should not be construed as limiting. Alternatively, these constituent elements of the USB socket 10 may be distributed in a plurality of different housings. For example, some functions of the control unit 101 may be provided for a housing different from the housing of the connection portion 2 (connection port 4). Alternatively, at least some functions of the control unit 101 may also be implemented as a server or a cloud computing system, for example.
此外，USB插座10不必被设计成室内使用，而且也可被设计成室外使用。在被设计成室外使用时，USB插座10可以适当地采用例如防雨(防滴漏)构造。Furthermore, the USB socket 10 need not be designed for indoor use, but may also be designed for outdoor use. When designed for outdoor use, the USB socket 10 may appropriately adopt, for example, a rainproof (dripproof) structure.
此外，在上述第一实施例中，假定要连接到USB插座10的装置9是可充电装置9。然而，这仅是示例，并且不应被解释为限制性的。可替代地，不可充电装置9(即，除可充电装置9以外的装置9)可以连接到USB插座10。In addition, in the first embodiment described above, it is assumed that the device 9 to be connected to the USB socket 10 is a rechargeable device 9. However, this is only an example and should not be construed as limiting. Alternatively, a non-rechargeable device 9 (i.e., a device 9 other than the rechargeable device 9) may be connected to the USB socket 10.
可选地，USB插座10可以具有类型识别能力，即，判断连接到USB插座10的装置9是否是可充电装置的能力。可以通过例如使USB插座10经由USB连接器91与装置9建立有线或无线通信来提供这种类型识别能力。提供这种类型识别能力使得USB插座10能够例如仅在可充电装置9连接到自身时才使检测单元12检测到监视值大于阈值(即，检测监视值的异常)。Optionally, the USB socket 10 may have a type recognition capability, that is, the capability to determine whether the device 9 connected to the USB socket 10 is a rechargeable device. This type recognition capability may be provided, for example, by enabling the USB socket 10 to establish wired or wireless communication with the device 9 via the USB connector 91. Providing this type recognition capability enables the USB socket 10 to, for example, enable the detection unit 12 to detect that the monitoring value is greater than a threshold value (that is, to detect an abnormality in the monitoring value) only when a rechargeable device 9 is connected to itself.
此外，USB插座10不必是嵌入式布线装置。也就是说，USB插座10也可以是被装配成其整体从诸如壁等的对象结构物81的表面露出的“露出式”布线装置。在这种情况下，使用露出式开关盒而不是嵌入式开关盒将USB插座10安装到对象结构物81上。可替代地，也可以使用除开关盒以外的安装构件(诸如夹紧金属配件等)将USB插座10安装到对象结构物81上。Furthermore, the USB socket 10 does not have to be an embedded wiring device. That is, the USB socket 10 may also be an "exposed" wiring device that is assembled so that its entirety is exposed from the surface of the target structure 81 such as a wall. In this case, the USB socket 10 is mounted on the target structure 81 using an exposed switch box instead of an embedded switch box. Alternatively, the USB socket 10 may be mounted on the target structure 81 using a mounting member other than a switch box (such as a clamping metal fitting).
此外，将壳体3附接到安装支架84上不是USB插座10的必要配置。可替代地，例如，壳体3可以形成安装支架84的一体部分。同样，将插座板8附接到安装支架84上也不是USB插座10的必要配置。相反，可以适当地省略插座板8。Furthermore, attaching the housing 3 to the mounting bracket 84 is not a necessary configuration of the USB socket 10. Alternatively, for example, the housing 3 may form an integral part of the mounting bracket 84. Likewise, attaching the socket plate 8 to the mounting bracket 84 is not a necessary configuration of the USB socket 10. Instead, the socket plate 8 may be appropriately omitted.
可选地，USB插座10还可以是例如针对诸如个人计算机等的装置所设置的。Alternatively, the USB socket 10 may also be provided for a device such as a personal computer.
此外，在上述第一实施例中，多个连接部2连接到单个电源电路11。然而，这不是USB插座10的必要配置。可替代地，可以针对多个连接部2中的各连接部单独地设置电源电路11。换句话说，USB插座10可以包括多个连接部2和与多个连接部2一对一地相关联的多个电源电路11。在这种情况下，多个连接部2中的各连接部从其关联的电源电路11接收单独地供给的电力，因此还针对多个连接部2中的各连接部单独地定义额定输出(电流或电力)。Furthermore, in the first embodiment described above, the plurality of connection parts 2 are connected to a single power supply circuit 11. However, this is not a necessary configuration of the USB socket 10. Alternatively, the power supply circuit 11 may be provided individually for each of the plurality of connection parts 2. In other words, the USB socket 10 may include a plurality of connection parts 2 and a plurality of power supply circuits 11 associated one-to-one with the plurality of connection parts 2. In this case, each of the plurality of connection parts 2 receives power supplied individually from its associated power supply circuit 11, and thus the rated output (current or power) is also defined individually for each of the plurality of connection parts 2.
此外，分配指示器32不必是压印到壳体3的正面31上的标记，而是还可以被实现为例如印刷字符、封条、指示灯(发光元件)或显示器。如果分配指示器32例如被实现为指示灯或显示器，则在分配指示器32上显示的信息也可以适当地改变。In addition, the dispensing indicator 32 does not have to be a mark stamped on the front surface 31 of the housing 3, but can also be implemented as, for example, printed characters, a seal, an indicator light (light emitting element), or a display. If the dispensing indicator 32 is implemented as, for example, an indicator light or a display, the information displayed on the dispensing indicator 32 can also be appropriately changed.
此外，分配指示器32不是USB插座10的必要构成元件，而是可以适当地省略。Furthermore, the allocation indicator 32 is not an essential constituent element of the USB socket 10 , but may be omitted as appropriate.
此外，使得检测单元12能够检测到监视值大于阈值(即，检测监视值的异常)的手段不必是监视(测量)电源电路11的输出电流，而是例如还可以是监视(测量)电源电路11的输出电力。还可替代地，检测单元12还可以通过除监视(测量)电源电路11的输出(电流或电力)以外的任何手段来检测到监视值大于阈值(即，检测到监视值的异常)。例如，检测单元12可以通过经由USB连接器91建立有线或无线通信来与连接到任何连接部2的装置9进行通信。这使得检测单元12能够通过与装置9进行通信来检测到监视值大于阈值(即，检测到监视值的异常)。In addition, the means by which the detection unit 12 can detect that the monitoring value is greater than the threshold value (i.e., detect an abnormality in the monitoring value) need not necessarily be monitoring (measuring) the output current of the power supply circuit 11, but may also be, for example, monitoring (measuring) the output power of the power supply circuit 11. Alternatively, the detection unit 12 may also detect that the monitoring value is greater than the threshold value (i.e., detect an abnormality in the monitoring value) by any means other than monitoring (measuring) the output (current or power) of the power supply circuit 11. For example, the detection unit 12 may communicate with the device 9 connected to any connection portion 2 by establishing wired or wireless communication via the USB connector 91. This enables the detection unit 12 to detect that the monitoring value is greater than the threshold value (i.e., detect an abnormality in the monitoring value) by communicating with the device 9.
此外，在上述实施例中，检测单元12针对多个连接部2中的各连接部单独地检测到监视值大于阈值(检测到监视值的异常)。然而，这不是USB插座10的必要配置。也就是说，检测单元12还可以针对多个连接部2一并地检测到监视值大于阈值(检测监视值的异常)。同样，在上述实施例中，警报单元102针对多个连接部2中的各连接部单独地发出警报，以指示监视值大于阈值(检测监视值的异常)。然而，这不是USB插座10的必要配置。也就是说，警报单元102还可以针对多个连接部2一并地发出警报，以指示监视值大于阈值(检测监视值的异常)。Furthermore, in the above-described embodiment, the detection unit 12 detects that the monitoring value is greater than the threshold value (detects an abnormality in the monitoring value) for each of the plurality of connection parts 2 individually. However, this is not a necessary configuration of the USB socket 10. That is, the detection unit 12 may also detect that the monitoring value is greater than the threshold value (detects an abnormality in the monitoring value) for the plurality of connection parts 2 collectively. Similarly, in the above-described embodiment, the alarm unit 102 issues an alarm individually for each of the plurality of connection parts 2 to indicate that the monitoring value is greater than the threshold value (detects an abnormality in the monitoring value). However, this is not a necessary configuration of the USB socket 10. That is, the alarm unit 102 may also issue an alarm collectively for the plurality of connection parts 2 to indicate that the monitoring value is greater than the threshold value (detects an abnormality in the monitoring value).
此外，警报单元102仅在监视值变得大于阈值时才必须发出警报。因此，检测单元12不是USB插座10的必要构成元件。也就是说，如果警报单元102代替检测单元12将监视值与阈值进行比较并且检测到监视值大于阈值，则可以适当地省略检测单元12。In addition, the alarm unit 102 must issue an alarm only when the monitoring value becomes greater than the threshold value. Therefore, the detection unit 12 is not an essential component of the USB socket 10. That is, if the alarm unit 102 compares the monitoring value with the threshold value instead of the detection unit 12 and detects that the monitoring value is greater than the threshold value, the detection unit 12 can be appropriately omitted.
可选地，警报单元102可以发出指示监视值本身(例如，电流的大小)的警报(进行通知)。例如，当监视值变得大于阈值时，警报单元102可以通过显示或发出声音来发出指示监视值本身的警报。此外，即使监视值不大于阈值，警报单元102也可以通过显示或发出声音来在任意定时(例如，按规则的间隔)发出指示监视值本身的警报。Alternatively, the alarm unit 102 may issue an alarm (notify) indicating the monitored value itself (e.g., the magnitude of the current). For example, when the monitored value becomes greater than a threshold value, the alarm unit 102 may issue an alarm indicating the monitored value itself by displaying or emitting a sound. In addition, even if the monitored value is not greater than the threshold value, the alarm unit 102 may issue an alarm indicating the monitored value itself at an arbitrary timing (e.g., at regular intervals) by displaying or emitting a sound.
此外，警报单元102包括显示单元14和声音发出单元15这两者，这不是USB插座10的必要配置。可替代地，可以从警报单元102中省略显示单元14或声音发出单元15。Furthermore, the alarm unit 102 includes both the display unit 14 and the sound emitting unit 15, which is not an essential configuration of the USB socket 10. Alternatively, the display unit 14 or the sound emitting unit 15 may be omitted from the alarm unit 102.
此外，显示单元14包括发光元件141和光学构件142，这不是USB插座10的必要配置。可替代地，显示单元14还可以被实现为诸如液晶显示器或有机电致发光(EL)显示器等的图像显示装置。Furthermore, the display unit 14 includes the light emitting element 141 and the optical member 142, which is not an essential configuration of the USB socket 10. Alternatively, the display unit 14 may also be implemented as an image display device such as a liquid crystal display or an organic electroluminescent (EL) display.
(第二实施例)(Second embodiment)
如图7所示，根据第二实施例的USB插座10D具有与通信终端62进行通信的能力，这是与根据第一实施例的USB插座10的主要区别。在以下的说明中，本第二实施例中的具有与上述第一实施例的对应物相同功能的任何构成元件将由与该对应物的附图标记相同的附图标记指定，并且这里将适当地省略其说明。7 , the USB socket 10D according to the second embodiment has the ability to communicate with the communication terminal 62, which is a major difference from the USB socket 10 according to the first embodiment. In the following description, any constituent element in this second embodiment having the same function as its counterpart in the above-described first embodiment will be designated by the same reference numeral as that of the counterpart, and description thereof will be appropriately omitted here.
也就是说，根据本实施例的USB插座10D包括通信单元61。通信单元61被配置为准备好与通信终端62进行通信。如本文所使用的，“准备好进行通信”意味着能够例如通过适当的有线或无线通信方法直接地或者经由网络或中继器间接地发送和接收信息。在本实施例中，例如，通信单元61可以通过网络与通信终端62双向通信。在本实施例中，通信单元61可以采用使用无线电波作为通信媒介的无线通信，该通信媒介符合和不需要许可的低功率无线电标准(指定低功率无线电)等的各种标准中的任何标准。That is, the USB socket 10D according to the present embodiment includes a communication unit 61. The communication unit 61 is configured to be ready to communicate with the communication terminal 62. As used herein, "ready to communicate" means being able to send and receive information, for example, directly or indirectly via a network or a repeater, by an appropriate wired or wireless communication method. In the present embodiment, for example, the communication unit 61 can communicate bidirectionally with the communication terminal 62 via a network. In the present embodiment, the communication unit 61 can adopt wireless communication using radio waves as a communication medium, which complies with Any of various standards such as a low-power radio standard (specified low-power radio) that does not require a license.
通信终端62是至少具有与通信单元61进行通信的能力的终端。通信终端62例如可以被实现为诸如智能电话、平板计算机或可穿戴终端等的移动通信装置、或者个人计算机。这种类型的通信终端62例如包括具有显示能力或声音发出能力的用户接口。在图7所示的示例中，通信终端62是与要连接到USB插座10D的装置9分开设置的平板终端。可替代地，通信终端62也可以是要连接到USB插座10D的装置9。The communication terminal 62 is a terminal having at least the ability to communicate with the communication unit 61. The communication terminal 62 can be implemented as a mobile communication device such as a smart phone, a tablet computer or a wearable terminal, or a personal computer. This type of communication terminal 62 includes, for example, a user interface having a display capability or a sound emitting capability. In the example shown in FIG. 7 , the communication terminal 62 is a tablet terminal that is separately provided from the device 9 to be connected to the USB socket 10D. Alternatively, the communication terminal 62 can also be the device 9 to be connected to the USB socket 10D.
在本实施例中，警报单元102具有使通信单元61将检测单元12的检测结果发送到通信终端62的能力。也就是说，检测单元12的检测结果从通信单元61被传送到通信终端62。具体地，在监视值变得大于阈值时，警报单元103使通信单元61将指示监视值已变得大于阈值的检测单元12的检测结果作为警报指令发送到通信终端62。在接收到检测单元12的检测结果时，通信终端62可以立即显示检测单元12的检测结果或者仅进行推送通知。在后者情况下，直到用户进行特定操作(即，对特定对象的操作)为止，通信终端62才可以显示检测单元12的检测结果。In the present embodiment, the alarm unit 102 has the ability to enable the communication unit 61 to send the detection result of the detection unit 12 to the communication terminal 62. That is, the detection result of the detection unit 12 is transmitted from the communication unit 61 to the communication terminal 62. Specifically, when the monitoring value becomes greater than the threshold value, the alarm unit 103 enables the communication unit 61 to send the detection result of the detection unit 12 indicating that the monitoring value has become greater than the threshold value as an alarm instruction to the communication terminal 62. Upon receiving the detection result of the detection unit 12, the communication terminal 62 can immediately display the detection result of the detection unit 12 or only push notification. In the latter case, the communication terminal 62 can display the detection result of the detection unit 12 until the user performs a specific operation (i.e., an operation on a specific object).
可以看出，根据本实施例，在发现监视值大于阈值时，警报单元102通过将警报指令经由通信发送到通信终端62来发出警报。这使得例如即使在USB插座10D位于用户的盲点或者远离用户的位置的情况下，用户也更容易经由通信终端62检查出检测单元12的检测结果。It can be seen that according to the present embodiment, when the monitoring value is found to be greater than the threshold value, the alarm unit 102 issues an alarm by sending an alarm instruction via communication to the communication terminal 62. This makes it easier for the user to check the detection result of the detection unit 12 via the communication terminal 62, for example, even if the USB socket 10D is located in the user's blind spot or a position far away from the user.
此外，如果如本实施例那样可以在通信单元61和通信终端62之间双向地建立通信，则警报单元102可以响应于来自通信终端62的呼出信号而将检测单元12的检测结果发送到通信终端62。也就是说，当通信单元61接收到来自通信终端62的呼出信号时，警报单元102将检测单元12的检测结果经由通信发送到通信终端62。这使得每当用户想要检查监视值的状态(监视值是否大于阈值)时，用户都能够在通信终端62上检查监视值的状态。Furthermore, if communication can be established bidirectionally between the communication unit 61 and the communication terminal 62 as in the present embodiment, the alarm unit 102 can transmit the detection result of the detection unit 12 to the communication terminal 62 in response to an outgoing call signal from the communication terminal 62. That is, when the communication unit 61 receives an outgoing call signal from the communication terminal 62, the alarm unit 102 transmits the detection result of the detection unit 12 to the communication terminal 62 via communication. This enables the user to check the status of the monitoring value on the communication terminal 62 whenever the user wants to check the status of the monitoring value (whether the monitoring value is greater than the threshold value).
此外，在根据本实施例的USB插座10D中，USB插座10D和通信终端62之间的通信是无线通信或电力线载波通信。也就是说，通信单元61通过使用无线电波作为媒介的无线通信或者使用电力线作为媒介的电力线载波通信来与通信终端62进行通信。在这种情况下，不需要将任何专用通信线路连接到USB插座10D。也就是说，即使在电力线载波通信的情况下，也不需要将任何专用通信线路连接到USB插座10D，更不必说无线通信的情况。也就是说，连接到端子部16的线L1是电力线。因此，通信单元61可以通过使用该线L1作为传输线来与通信终端62建立电力线载波通信。可选地，通信单元61可以通过使用无线通信和电力线载波通信这两者来与通信终端62进行通信。Furthermore, in the USB socket 10D according to the present embodiment, the communication between the USB socket 10D and the communication terminal 62 is wireless communication or power line carrier communication. That is, the communication unit 61 communicates with the communication terminal 62 by wireless communication using radio waves as a medium or power line carrier communication using power lines as a medium. In this case, it is not necessary to connect any dedicated communication line to the USB socket 10D. That is, even in the case of power line carrier communication, it is not necessary to connect any dedicated communication line to the USB socket 10D, not to mention the case of wireless communication. That is, the line L1 connected to the terminal portion 16 is a power line. Therefore, the communication unit 61 can establish power line carrier communication with the communication terminal 62 by using the line L1 as a transmission line. Alternatively, the communication unit 61 can communicate with the communication terminal 62 by using both wireless communication and power line carrier communication.
可以适当地组合针对第一实施例(包括其变形例)所述的各种配置来采用针对第二实施例(包括其变形例)所述的配置。The configuration described for the second embodiment (including its modified examples) may be adopted by appropriately combining the various configurations described for the first embodiment (including its modified examples).
(第三实施例)(Third Embodiment)
如图8所示，根据第三实施例的USB插座10E包括限制器电路17，这是与根据第一实施例的USB插座10的主要区别。在以下的说明中，该第三实施例中的具有与上述第一实施例的对应物相同的功能的任何构成元件将由与该对应物的附图标记相同的附图标记指定，并且这里将适当地省略其说明。8 , the USB socket 10E according to the third embodiment includes a limiter circuit 17, which is a major difference from the USB socket 10 according to the first embodiment. In the following description, any constituent element in this third embodiment having the same function as its counterpart in the above-described first embodiment will be designated by the same reference numeral as that of the counterpart, and description thereof will be appropriately omitted here.
限制器电路17在发现监视值大于第一阈值或第二阈值时，限制要从USB插座10E(电源电路11)供给到装置9的电力。如本文所使用的，“第一阈值”是用于使警报单元102判断是否发出警报的阈值。此外，如本文所使用的“第二阈值”是与第一阈值不同的阈值。第二阈值可以大于第一阈值或小于第一阈值，无论哪种都是适当的。在本实施例中，例如，第二阈值可以大于第一阈值，并且限制器电路17在发现监视值大于第二阈值时，可以限制从电源电路11供给到装置9的电力。The limiter circuit 17 limits the power to be supplied from the USB socket 10E (power supply circuit 11) to the device 9 when it is found that the monitoring value is greater than the first threshold value or the second threshold value. As used herein, the "first threshold value" is a threshold value for causing the alarm unit 102 to determine whether to issue an alarm. In addition, the "second threshold value" as used herein is a threshold value different from the first threshold value. The second threshold value may be greater than the first threshold value or less than the first threshold value, whichever is appropriate. In the present embodiment, for example, the second threshold value may be greater than the first threshold value, and the limiter circuit 17 may limit the power supplied from the power supply circuit 11 to the device 9 when it is found that the monitoring value is greater than the second threshold value.
也就是说，在根据本实施例的USB插座10E中，在监视值变得大于第一阈值时，警报单元102发出警报。另外，在该USB插座10E中，在发现监视值大于第二阈值(其比第一阈值大)时，限制器电路17限制从电源电路11供给到装置9的电力。如本文所使用的，“限制电力”是指减少电力并切断电力(即，切断电力供给)。在本实施例中，假定限制器电路17通过减少要从电源电路11供给到装置9的电力来限制电力。That is, in the USB socket 10E according to the present embodiment, when the monitoring value becomes larger than the first threshold value, the alarm unit 102 issues an alarm. In addition, in this USB socket 10E, when the monitoring value is found to be larger than the second threshold value (which is larger than the first threshold value), the limiter circuit 17 limits the power supplied from the power supply circuit 11 to the device 9. As used herein, "limiting power" means reducing power and cutting off power (i.e., cutting off power supply). In the present embodiment, it is assumed that the limiter circuit 17 limits power by reducing the power to be supplied from the power supply circuit 11 to the device 9.
限制器电路17可以通过例如控制电源电路11中所包括的开关元件来减少电源电路11的输出电流并减少从电源电路11供给到装置9的电力。可替代地，限制器电路17可以通过提取从电源电路11供给的电流的一部分来减少从电源电路11供给到连接部2的输出电流并且减少从电源电路11供给到装置9的电力。限制器电路17例如在发现监视值(例如，在该示例中为电流的大小)大于第二阈值时，可以将从电源电路11供给到装置9的电流减少到第一阈值或更小。The limiter circuit 17 can reduce the output current of the power supply circuit 11 and reduce the power supplied from the power supply circuit 11 to the device 9 by, for example, controlling a switching element included in the power supply circuit 11. Alternatively, the limiter circuit 17 can reduce the output current supplied from the power supply circuit 11 to the connection portion 2 and reduce the power supplied from the power supply circuit 11 to the device 9 by extracting a portion of the current supplied from the power supply circuit 11. The limiter circuit 17 can reduce the current supplied from the power supply circuit 11 to the device 9 to the first threshold or less, for example, when it is found that the monitoring value (for example, the magnitude of the current in this example) is greater than the second threshold.
从上述说明可以看出，根据本实施例的USB插座10E包括限制器电路17，该限制器电路17用于在发现监视值大于阈值或者大于与作为阈值的第一阈值不同的第二阈值时，限制要供给到装置9的电力。这可以减少例如在将过大电流从电源电路11供给到装置9时施加到电源电路11和装置9的应力。限制器电路17不必被配置为在如上所述发现监视值大于第二阈值时限制电力，而是还可以在发现监视值大于第一阈值(阈值)时限制电力。As can be seen from the above description, the USB outlet 10E according to the present embodiment includes the limiter circuit 17 for limiting the power to be supplied to the device 9 when the monitoring value is found to be larger than the threshold value or larger than the second threshold value different from the first threshold value as the threshold value. This can reduce the stress applied to the power supply circuit 11 and the device 9 when, for example, an excessive current is supplied from the power supply circuit 11 to the device 9. The limiter circuit 17 does not have to be configured to limit the power when the monitoring value is found to be larger than the second threshold value as described above, but can also limit the power when the monitoring value is found to be larger than the first threshold value (threshold value).
在第三实施例的一个变形例中，第二阈值可以小于第一阈值。In a variation of the third embodiment, the second threshold may be smaller than the first threshold.
可以适当地组合针对第一实施例或第二实施例(包括它们的变形例)所述的各种配置来采用针对第三实施例(包括其变形例)所述的配置。The configuration described for the third embodiment (including its modified examples) may be adopted by appropriately combining the various configurations described for the first embodiment or the second embodiment (including their modified examples).
(概括)(Summary)
根据第一方面的USB插座(10,10A-10E)包括连接部(2)、电源电路(11)、壳体(3)和警报单元(102)。装置(9)的USB连接器(91)可电连接到连接部(2)。电源电路(11)从连接部(2)向装置(9)供给电力。壳体(3)在内部容纳电源电路(11)。警报单元(102)在发现监视值大于阈值时发出警报。监视值是以下项中的至少一个：要供给到装置(9)的电流的大小、要供给到装置(9)的电流的累计值、要供给到装置(9)的电力的大小、要供给到装置(9)的电能、以及向装置(9)供给电力的时间长度。A USB socket (10, 10A-10E) according to a first aspect comprises a connection portion (2), a power circuit (11), a housing (3) and an alarm unit (102). A USB connector (91) of a device (9) can be electrically connected to the connection portion (2). The power circuit (11) supplies power to the device (9) from the connection portion (2). The housing (3) accommodates the power circuit (11) inside. The alarm unit (102) issues an alarm when a monitoring value is found to be greater than a threshold value. The monitoring value is at least one of the following items: the magnitude of a current to be supplied to the device (9), the cumulative value of the current to be supplied to the device (9), the magnitude of the power to be supplied to the device (9), the electric energy to be supplied to the device (9), and the length of time for which power is supplied to the device (9).
根据该方面，在监视值(诸如要从电源电路(11)供给到装置(9)的电流的大小等)变得大于阈值时，警报单元(102)发出警报。因此，如果例如将比电源电路(11)的额定输出(电流或电力)大的过大电流或电力从USB插座(10,10A-10E)供给到装置(9)，则可以向用户警报这种异常。这使得能够对监视值(诸如要供给到装置(9)的电流的大小等)的任何异常向用户提供早期警报，由此有助于提高USB插座(10,10A-10E)的可靠性。因此，可以提供更有效地有助于提高可靠性的USB插座(10,10A-10E)。According to this aspect, when a monitoring value (such as the magnitude of the current to be supplied from the power supply circuit (11) to the device (9)) becomes greater than a threshold value, the alarm unit (102) issues an alarm. Therefore, if, for example, an excessive current or power greater than the rated output (current or power) of the power supply circuit (11) is supplied from the USB socket (10, 10A-10E) to the device (9), the user can be alerted to such abnormality. This makes it possible to provide an early warning to the user of any abnormality in the monitoring value (such as the magnitude of the current to be supplied to the device (9)), thereby contributing to improving the reliability of the USB socket (10, 10A-10E). Therefore, a USB socket (10, 10A-10E) that more effectively contributes to improving reliability can be provided.
可以结合第一方面来实现的根据第二方面的USB插座(10,10A-10E)还包括检测单元(12)。检测单元(12)将监视值与阈值进行比较，并且检测到监视值大于阈值。警报单元(102)发出指示检测单元(12)的检测结果的警报。The USB socket (10, 10A-10E) according to the second aspect, which can be implemented in combination with the first aspect, further includes a detection unit (12). The detection unit (12) compares the monitoring value with a threshold value and detects that the monitoring value is greater than the threshold value. The alarm unit (102) issues an alarm indicating the detection result of the detection unit (12).
根据该方面，警报单元(102)仅发出指示检测单元(12)的检测结果的警报，由此简化警报单元(102)的配置。According to this aspect, the alarm unit (102) only issues an alarm indicating the detection result of the detection unit (12), thereby simplifying the configuration of the alarm unit (102).
可以结合第一方面或第二方面来实现的根据第三方面的USB插座(10,10A-10E)还包括限制器电路(17)。限制器电路(17)在监视值变得大于作为阈值的第一阈值或不同于第一阈值的第二阈值时，限制要供给到装置(9)的电力。The USB socket (10, 10A-10E) according to the third aspect, which can be implemented in combination with the first aspect or the second aspect, further includes a limiter circuit (17). The limiter circuit (17) limits the power to be supplied to the device (9) when the monitoring value becomes greater than a first threshold value as a threshold value or a second threshold value different from the first threshold value.
该方面可以减少例如在将过大电流从电源电路(11)供给到装置(9)时施加到电源电路(11)和装置(9)的应力。This aspect can reduce stress applied to the power supply circuit (11) and the device (9) when, for example, an excessive current is supplied from the power supply circuit (11) to the device (9).
在可以结合第一方面至第三方面中任一方面来实现的根据第四方面的USB插座(10,10A-10E)中，警报单元(102)包括设置在壳体(3)的正面上的显示单元(14)。警报单元(102)通过显示单元(14)的显示模式来发出警报。In the USB socket (10, 10A-10E) according to the fourth aspect which can be implemented in combination with any one of the first to third aspects, the alarm unit (102) includes a display unit (14) provided on the front surface of the housing (3). The alarm unit (102) issues an alarm through a display mode of the display unit (14).
根据该方面，通过显示单元(14)上的显示模式向用户警报监视值的任何异常，由此使得用户能够更容易地掌握监视值的异常。According to this aspect, the user is alerted to any abnormality of the monitoring value by the display mode on the display unit (14), thereby enabling the user to grasp the abnormality of the monitoring value more easily.
在可以结合第一方面至第四方面中任一方面来实现的根据第五方面的USB插座(10,10A-10E)中，警报单元(102)在发现监视值大于阈值时，通过与通信终端(62)建立通信以向通信终端(62)发送警报指令来发出警报。In the USB socket (10, 10A-10E) according to the fifth aspect which can be implemented in combination with any one of the first to fourth aspects, when the alarm unit (102) finds that the monitoring value is greater than a threshold value, it issues an alarm by establishing communication with the communication terminal (62) to send an alarm instruction to the communication terminal (62).
根据该方面，对监视值异常的警报由通信终端(62)发出，由此使得用户能够更容易地掌握监视值的异常。According to this aspect, an alarm for abnormality of the monitoring value is issued by the communication terminal (62), thereby enabling the user to more easily grasp the abnormality of the monitoring value.
在可以结合第五方面来实现的根据第六方面的USB插座(10,10A-10E)中，与通信终端(62)的通信是无线通信或电力线载波通信。In the USB socket (10, 10A-10E) according to the sixth aspect which can be implemented in combination with the fifth aspect, the communication with the communication terminal (62) is wireless communication or power line carrier communication.
该方面便于在USB插座(10,10A-10E)和通信终端(62)之间建立通信。This aspect facilitates establishing communications between the USB receptacle (10, 10A-10E) and the communication terminal (62).
在可以结合第一方面至第六方面中任一方面来实现的根据第七方面的USB插座(10,10A-10E)中，连接部(2)包括多个连接部(2)。在壳体(3)的正面上设置有分配指示器(32)，该分配指示器(32)用于提供与针对多个连接部(2)中的各连接部要输出的电力的大小有关的输出信息。In the USB socket (10, 10A-10E) according to the seventh aspect which can be implemented in combination with any one of the first to sixth aspects, the connection part (2) includes a plurality of connection parts (2). A distribution indicator (32) is provided on the front surface of the housing (3), and the distribution indicator (32) is used to provide output information related to the amount of power to be output for each of the plurality of connection parts (2).
根据该方面，在存在多个连接部(2)的情形下使分配指示器(32)提供这样的输出信息减少了用户对从多个连接部(2)中选择要使用的连接部(2)犹豫不决的可能性。According to this aspect, having the allocation indicator (32) provide such output information when a plurality of connections (2) are present reduces the likelihood that the user will hesitate to select a connection (2) to be used from the plurality of connections (2).
