本发明涉及一种插座，尤其涉及一种安装触点开关的插座。The invention relates to a socket, in particular to a socket installed with a contact switch.
背景技术Background technique
音频插座是各种播放声音的电子设备上广泛使用的设备，如常见的3.5mm标准音频插座，其中安装有触点开关。触点开关是指一个利用导电接触部分可以使电路开路、接通，使电流中断或使其流到其他电路的开关。通过触点开关和3.5mm的音频插头配合可以输出立体声音频。随着用户需求的不断出现，要求音频插座能实现更多的功能，这就要求在音频插座中设置尽可能多的开关，同时还希望插座的体积尽可能保持紧凑，即在增加插座功能的情况下，尽可能不增加甚至减小其体积。Audio sockets are widely used on various electronic devices that play sound, such as common 3.5mm standard audio sockets, in which contact switches are installed. A contact switch refers to a switch that uses a conductive contact part to open or connect a circuit, interrupt the current, or allow it to flow to other circuits. Stereo audio can be output through the contact switch and the 3.5mm audio plug. With the continuous emergence of user needs, audio sockets are required to achieve more functions, which requires as many switches as possible to be set in the audio sockets, and it is also hoped that the volume of the sockets should be kept as compact as possible, that is, in the case of increasing socket functions , without increasing or even reducing its volume as much as possible.
以下以一种在汽车中实现两套多媒体播放设备自动切换的具体应用为例进行说明。汽车中都安装汽车自带多媒体播放设备以播放多媒体，通常汽车自带的多媒体播放设备都安装在汽车的前排区域，便于驾驶员进行多媒体播放的操作。随着移动多媒体播放设备(例如Mp3，Mp4播放器或者手机)的普及，坐在后排的乘客希望在后排可方便的将移动多媒体播放设备中的多媒体文件也在汽车中播放出来，更理想的是，能实现在汽车前排的自带多媒体播放设备和后排乘客的移动多媒体播放设备输入输出的自动切换。The following is an example of a specific application that realizes the automatic switching of two sets of multimedia playback devices in a car. Automobiles are equipped with self-carrying multimedia player devices to play multimedia, and usually the car's own multimedia player devices are installed in the front row area of the car, which is convenient for the driver to perform multimedia player operations. With the popularization of mobile multimedia playback devices (such as Mp3, Mp4 players or mobile phones), passengers sitting in the back row hope that the multimedia files in the mobile multimedia playback device can also be played in the car conveniently in the back row, which is more ideal. The most important thing is that it can realize the automatic switching of the input and output of the built-in multimedia player equipment in the front row of the car and the mobile multimedia player equipment of the rear passengers.
现有技术中可以通过一个已有的音频插座和继电器的组合来实现上述功能。图1a示出了实现上述功能的音频插座1和继电器1’的接线原理图，此时多媒体移动设备的输出端子(插头)尚未插入音频插座1。音频插座1中的开关#4、#5相连，#2、#7相连，#8、#1，#6、#3相连，继电器1’中的开关A1、A2相连，B1、B2相连；此时车内多媒体播放设备音频信号由⑦、⑧输入，①、②输出，视频信号由输入，⑨、⑩输出。此时继电器起到一个附加开关的作用。In the prior art, the above functions can be realized through a combination of an existing audio socket and a relay. Fig. 1a shows a schematic diagram of the wiring of the audio socket 1 and the relay 1' to realize the above functions, and the output terminal (plug) of the multimedia mobile device has not been inserted into the audio socket 1 at this time. Switches #4 and #5 in audio socket 1 are connected, #2 and #7 are connected, #8, #1, #6 and #3 are connected, switches A1 and A2 in relay 1' are connected, and B1 and B2 are connected; The audio signal of the multimedia playback equipment in the car is input by ⑦, ⑧, output by ①, ②, and the video signal is output by Input, ⑨, ⑩ output. In this case the relay acts as an additional switch.
图1b则显示了将移动多媒体设备输出端子插入插座后，图1a中显示的音频插座1和继电器1’中的开关状态均发生切换，即#4、#5断开，#2、#7断开，#8、#1断开，#6、#3断开，继电器1’内A2和A1断开而与A3相连，B2和B1断开而与B3相连。此时，音频信号直接由移动设备通过①、②输出，视频信号直接由⑩输出(目前大部分移动设备无法输出双通道视频信号，所以由⑩输出)。图1a和图1b中L，R分别表示左右声道音频，GND表示接地，Shielding表示屏蔽，Y表示视频，Y+，Y-表示双通道视频。Figure 1b shows that after the output terminal of the mobile multimedia device is inserted into the socket, the switching states of the audio socket 1 and the relay 1' shown in Figure 1a are switched, that is, #4 and #5 are disconnected, and #2 and #7 are disconnected. Open, #8 and #1 are disconnected, #6 and #3 are disconnected, A2 and A1 in the relay 1' are disconnected and connected to A3, B2 and B1 are disconnected and connected to B3. At this time, the audio signal is directly output by the mobile device through ① and ②, and the video signal is directly output by ⑩ (currently most mobile devices cannot output dual-channel video signal, so it is output by ⑩). In Figure 1a and Figure 1b, L and R represent left and right channel audio, GND represents grounding, Shielding represents shielding, Y represents video, Y+ , Y- represents dual-channel video.
虽然上述音频插座和继电器的组合能实现上述功能，但是其缺点也是显而易见的，即要使用两个部件才能实现上述功能，所以产品成本高；另外使用继电器则需要提供额外的电源，这也使得汽车设计更加复杂。Although the combination of the above-mentioned audio socket and relay can realize the above-mentioned functions, its disadvantages are also obvious, that is, two components are used to realize the above-mentioned functions, so the product cost is high; in addition, the use of relays requires additional power supply, which also makes the car The design is more complicated.
所以希望提供一种改进的插座，只需要一个插座而无需使用继电器就可以实现上述两套多媒体播放设备的自动切换，从而降低产品成本并且简化设计。当然，也希望这种改进的插座依然具有非常紧凑的结构，最好相对于现有的标准插座尽可能不增加占用的空间，同时能兼容现有的标准插头。Therefore, it is desired to provide an improved socket, which can realize the automatic switching of the above two sets of multimedia playback devices with only one socket without using a relay, thereby reducing the product cost and simplifying the design. Of course, it is also hoped that this improved socket still has a very compact structure, and preferably does not increase the occupied space as much as possible compared with the existing standard socket, and at the same time, it can be compatible with the existing standard plug.
所以还希望提供一种改进的插座，其仅仅通过对插座内开关端子结构、位置的改进，就使得插座能实现更多的功能而且仍然保持非常紧凑的结构。Therefore, it is also desired to provide an improved socket, which enables the socket to realize more functions and maintain a very compact structure only by improving the structure and position of the switch terminals in the socket.
所以希望提供一种改进的插座，其使用的触点开关结构简单，经久耐用，制造成本低。Therefore, it is desirable to provide an improved socket whose contact switch is simple in structure, durable and low in manufacturing cost.

具体实施方式Detailed ways
下面将参考构成本说明书一部分的附图对本发明的各种具体实施方式进行描述。应该理解的是，虽然在本发明中使用表示方向的术语，诸如“前”、“后”、“上”、“下”等描述本发明的各种示例结构部分和元件，但是在此使用这些术语只是为了方便说明的目的，基于附图中显示的示例方位而确定的。由于本发明所公开的实施例可以按照不同的方向设置，所以这些表示方向的术语只是作为说明而不应视作为限制。在可能的情况下，本发明中使用的相同或者相类似的附图标记指的是相同的部件。Various embodiments of the invention will be described below with reference to the accompanying drawings, which form a part hereof. It should be understood that although directional terms, such as "front," "rear," "upper," "lower," etc., are used herein to describe various exemplary structural parts and elements of the invention, these Terminology is for explanatory purposes only, based on the example orientations shown in the figures. Since the disclosed embodiments of the present invention may be arranged in different orientations, these directional terms are for illustration only and should not be viewed as limiting. Where possible, the same or similar reference numerals used in the present invention refer to the same components.
图2显示了本发明公开的一种插座2。插座包括壳体3，在壳体3内具有允许插头50进出的通道40，在通道40的上方有多个(如4个)沿水平方向设置的触点开关20a-20d。同时，在通道40的左右方都设有沿垂直方向设置的触点开关30a和30b。触点开关20a-20d以及30a和30b都设置为当插头50进入通道40时与插头50相接触，当插头50插入和拔出所述通道40时，插头50的移动可带动触点开关20a-20d上下移动和触点开关30a-30b左右移动。Fig. 2 shows a socket 2 disclosed by the present invention. The socket includes a housing 3, in which there is a channel 40 allowing the plug 50 to come in and out, above the channel 40 there are multiple (eg 4) contact switches 20a-20d arranged in the horizontal direction. Meanwhile, contact switches 30 a and 30 b arranged vertically are provided on the left and right sides of the channel 40 . The contact switches 20a-20d and 30a and 30b are all arranged to be in contact with the plug 50 when the plug 50 enters the channel 40, and when the plug 50 is inserted into and pulled out of the channel 40, the movement of the plug 50 can drive the contact switches 20a- 20d moves up and down and contact switches 30a-30b move left and right.
图3显示了一个触点开关20a的示例性结构(开关20a-20d可具有相同的结构)。开关20a具有端子100a和200a，端子100a具有一个接触部分110a和弹性臂120a，端子200a具有接触部分210a，接触部分110a位于接触部分210a的上方。当插头没有插入时，接触部分110a与接触部分210a选择性地接触，开关20a闭合。可选的，接触部分和弹性臂形状是如图所示的细长薄片，这种形状有利于端子的弹性变形，使得端子具有非常强的耐用性，而且便于加工制造降低成本。并且，通过调整端子的长度和宽度可以进一步改善起弹性变形的性能，延长其使用寿命。可选的，端子200a可以像图3所示的那样具有弹性臂220a，这样端子100a和200a具有几乎相同的结构，便于加工制造并降低成本。FIG. 3 shows an exemplary structure of a contact switch 20a (switches 20a-20d may have the same structure). The switch 20a has terminals 100a and 200a, the terminal 100a has a contact portion 110a and an elastic arm 120a, the terminal 200a has a contact portion 210a, and the contact portion 110a is located above the contact portion 210a. When the plug is not inserted, the contact portion 110a selectively contacts the contact portion 210a, and the switch 20a is closed. Optionally, the shape of the contact portion and the elastic arm is an elongated sheet as shown in the figure, which is conducive to the elastic deformation of the terminal, makes the terminal very durable, and is convenient for processing and manufacturing to reduce costs. Moreover, by adjusting the length and width of the terminal, the performance of elastic deformation can be further improved and the service life thereof can be prolonged. Optionally, the terminal 200a may have an elastic arm 220a as shown in FIG. 3 , so that the terminals 100a and 200a have almost the same structure, which facilitates manufacturing and reduces costs.
插头50沿通道40插入插座3后，其插入到端子100a弹性臂120a的下方与弹性臂120a相接触，弹性臂120a可在插头50插入力的作用下向上偏移，从而接触部分110a和200a脱离接触，开关20a断开。端子100a和200a以及插头50都包括导电材料使得其相互接触时，能实现电连接。After the plug 50 is inserted into the socket 3 along the channel 40, it is inserted into the terminal 100a below the elastic arm 120a to contact the elastic arm 120a, and the elastic arm 120a can be displaced upward under the action of the insertion force of the plug 50, so that the contact parts 110a and 200a are disengaged contact, the switch 20a is turned off. Both the terminals 100a and 200a and the plug 50 include conductive material so that when they are in contact with each other, an electrical connection can be achieved.
图4更加清楚的显示了作为优选实施例的开关20a其端子弹性臂和接触部分的细节。端子210a的接触部分上具有向上凸出的凸起215a，接触部分210a通过凸起215a与接触部分110a接触。虽然图中没有显示，但是可以理解，也可以选择在接触部分110a上设置向下凸出的凸起，接触部分110a通过该向下的凸起和接触部分210a相接触。还应当理解，虽然在接触部分110a或210a上设置凸起有利于减小两个端子之间的接触面积，使得开关在插头插入后更容易断开而更加灵敏，然而不设置凸起的端子也在本发明的保护范围之内。另外，凸起215a的设置方式也可以是多种多样，只要形成的凸起能实现上述效果即可，比如可以是在接触部分210a的下侧冲压使得受冲压部分向上凸出，从而在接触部分的上侧形成凸起215a，也可以是接触部分210a整体直接向上弯曲形成凸起，例如，通过弯折工艺将端子200的接触部分210a向上弯折形成凸起215a，还可以在接触部分上另外附上一个凸起(比如焊上一个金属凸起)；同理，在接触部分110a上形成向下凸起亦是如此。FIG. 4 shows more clearly the details of the elastic arm and the contact portion of the terminal of the switch 20a as a preferred embodiment. The contact portion of the terminal 210a has an upwardly protruding protrusion 215a, and the contact portion 210a is in contact with the contact portion 110a through the protrusion 215a. Although not shown in the figure, it can be understood that a downward protruding protrusion may also be provided on the contact portion 110a, and the contact portion 110a contacts the contact portion 210a through the downward protrusion. It should also be understood that although providing a protrusion on the contact portion 110a or 210a is conducive to reducing the contact area between the two terminals, making the switch easier to disconnect and more sensitive after the plug is inserted, a terminal without protrusions is also Within the protection scope of the present invention. In addition, the protrusion 215a can also be arranged in a variety of ways, as long as the formed protrusion can achieve the above effect, for example, it can be stamped on the lower side of the contact part 210a so that the stamped part protrudes upwards, so that the contact part 210a The upper side of the terminal 200 forms a protrusion 215a, or the entire contact portion 210a can be directly bent upward to form a protrusion. For example, the contact portion 210a of the terminal 200 is bent upward to form a protrusion 215a through a bending process. Attaching a protrusion (such as soldering a metal protrusion); similarly, forming a downward protrusion on the contact portion 110a is the same.
可选的，弹性臂120a还设有向下凸出的凸出部126a，凸出部126a的位置设置为当插头50插入通道时，插头50推动所述凸出部126a，使得接触部分110a和210a脱离接触。设置向下凸出部126a能使得插头50更加容易地推动第一端子的弹性臂120a，从而开关20a在插头50插入后更容易断开而更加灵敏。凸出部126a也可以有类似上述凸起215a的多种设置方式，只要形成的凸出部能实现上述凸出部的效果即可。Optionally, the elastic arm 120a is also provided with a protruding portion 126a protruding downwards, and the position of the protruding portion 126a is set so that when the plug 50 is inserted into the channel, the plug 50 pushes the protruding portion 126a, so that the contact portion 110a and 210a disengages. The provision of the downward protruding portion 126a can make it easier for the plug 50 to push the elastic arm 120a of the first terminal, so that the switch 20a is easier to disconnect and more sensitive after the plug 50 is inserted. The protruding part 126a can also have various arrangement methods similar to the above-mentioned protruding part 215a, as long as the formed protruding part can realize the effect of the above-mentioned protruding part.
可选的，端子100a的接触部分110a还具有向上拱起结构116a，如图所示其可以容纳端子200a的末端部分，其有助于端子100a和200a在水平方向上的相对位置设置。在图3所示的示例中，通过在端子100的接触部分110a设置一向上拱起结构116a，端子100a和端子200a各自的弹性臂120a、220a可设置在相同的水平位置。Optionally, the contact portion 110a of the terminal 100a also has an upwardly arched structure 116a, which can accommodate the end portion of the terminal 200a as shown in the figure, which facilitates relative positioning of the terminals 100a and 200a in the horizontal direction. In the example shown in FIG. 3 , by providing an upwardly arched structure 116a on the contact portion 110a of the terminal 100 , the respective elastic arms 120a, 220a of the terminal 100a and the terminal 200a can be arranged at the same horizontal position.
现在回到图3，端子100a可选的具有从弹性臂120a垂直延伸的连接臂130a和从所述弹性臂220垂直延伸的连接臂230a；当端子200a不具有弹性臂220a时，连接臂230a从端子200a的接触部分210a垂直延伸。当然，连接臂也可以不垂直延伸。通过连接臂将端子100和200固定在插座中，连接臂的末端形成相应端子的固定端，这种结构有助于弹性臂120a在受到插头50的插入力时向上的弹性变形，延长弹性臂的使用寿命。Returning now to Fig. 3, the terminal 100a optionally has a connecting arm 130a extending vertically from the elastic arm 120a and a connecting arm 230a extending vertically from the elastic arm 220; The contact portion 210a of the terminal 200a extends vertically. Of course, the connecting arm can also not extend vertically. The terminals 100 and 200 are fixed in the receptacle through the connecting arms, and the ends of the connecting arms form the fixed ends of the corresponding terminals. This structure helps the elastic arm 120a to elastically deform upward when it is subjected to the insertion force of the plug 50, and prolongs the length of the elastic arm. service life.
本领域技术人员还可以理解，端子100a和200a也可以不具有连接臂，例如端子100a的弹性臂120a和端子200a的弹性臂220a(如果没有弹性臂则是接触部分210a)各自和其自由端相对的末端分别形成端子100a和200a的固定端，直接固定在壳体3内。这种结构端子的至少一个好处是通道40轴向左右两侧的空间可以更充分的被进一步利用。Those skilled in the art can also understand that the terminals 100a and 200a may not have connecting arms, for example, the elastic arm 120a of the terminal 100a and the elastic arm 220a of the terminal 200a (if there is no elastic arm, then the contact portion 210a) is opposite to its free end The ends of the terminals form the fixed ends of the terminals 100a and 200a respectively, and are directly fixed in the housing 3 . At least one advantage of this structural terminal is that the space on the left and right sides of the channel 40 can be further utilized more fully.
可选的，端子100a的弹性臂120a和端子200a的弹性臂220a的延伸方向在同一直线上，这样的排列可以减少开关实际占用的插座内部空间，可以设置更多的开关。进一步可选的，弹性臂120a和220a均垂直于通道40的轴向延伸。Optionally, the extending direction of the elastic arm 120a of the terminal 100a and the elastic arm 220a of the terminal 200a are on the same straight line. Such an arrangement can reduce the internal space of the socket actually occupied by the switch, and more switches can be provided. Further optionally, both the elastic arms 120 a and 220 a extend perpendicular to the axial direction of the channel 40 .
尽管图中没有显示，但是本领域技术人员应当理解，还可以同时在通道40的下方以与开关20a-20d相同的方式设置与开关20a相同的开关。Although not shown in the figure, those skilled in the art should understand that the same switch as the switch 20a can also be provided below the channel 40 in the same manner as the switches 20a-20d.
开关20a的结构和布置方式使得插座2充分利用通道40的轴向长度从而有效的利用了通道的上方空间，并且不会影响通道40轴向左右两侧空间的利用，使得在不改变标准插座的尺寸或者尽可能保持紧凑的插座尺寸的前提下，有效地布置更多的开关，使插座实现更多的功能。The structure and arrangement of the switch 20a make the socket 2 make full use of the axial length of the channel 40 so as to effectively use the space above the channel, and will not affect the utilization of the space on the left and right sides of the channel 40 axially, so that the standard socket does not change. On the premise of keeping the size of the socket as compact as possible, more switches are effectively arranged, so that the socket can realize more functions.
图5a和图5b显示了开关30a和30b的示例性结构。其中图5a显示了插头50尚未插入通道40时开关30a和30b的状态，图5b显示了插头50插入通道40后开关30a和30b的状态。以下以位于通道左侧的触点开关30a为例进行说明，位于通道右侧的触点开关30b具有与开关30a对称的结构。Figures 5a and 5b show exemplary structures of switches 30a and 30b. 5a shows the state of the switches 30a and 30b when the plug 50 has not been inserted into the passage 40, and FIG. 5b shows the state of the switches 30a and 30b after the plug 50 is inserted into the passage 40. In the following, the contact switch 30a located on the left side of the channel is taken as an example for illustration, and the contact switch 30b located on the right side of the channel has a symmetrical structure with the switch 30a.
开关30a具有两个不动部分310a、330a和可动部分320a。可选的，不动部分和可动部分主体基本为扁平的长条形。沿着左右方向，从通道40开始向左依次设置不动部分310a，可动部分320a和不动部分330a，不动部分310a、330a和可动部分320a整体上沿平行于通道40的轴向方向延伸。上述不动部分和可动部分的形状和排列都有利于开关30a充分利用通道40轴向两侧的空间。The switch 30a has two stationary parts 310a, 330a and a movable part 320a. Optionally, the bodies of the fixed part and the movable part are basically flat and long. Along the left-right direction, a fixed part 310a, a movable part 320a and a fixed part 330a are provided sequentially from the channel 40 to the left, and the fixed parts 310a, 330a and the movable part 320a are generally along the axial direction parallel to the channel 40 extend. The shape and arrangement of the above-mentioned fixed part and movable part are favorable for the switch 30a to make full use of the space on both sides of the axial direction of the channel 40 .
可动部分320a具有固定末端321a和活动末端322a，当插头50没有插入通道40时，可动部分320a接触不动部分310a可形成电连接，此时可动部分320a不接触不动部分330a。当插头50插入通道40后，插头50推动活动末端322a相对于固定末端321a向左偏转，使可动部分320a与不动部分310a脱离接触而与不动部分330a接触，形成另一路电连接；而当插头拔出通道40后，活动末端322a失去插头施加的推力而复位。从而实现随着插头50的插入和拔出开关30a自动在两个电路之间切换。应当理解，具有两个不动部分310a和330a和一个可动部分320a的开关30是一种示例性实施例，其可以分别切换两条不同的电路，但是根据具体插座功能的需要，只包括一个不动部分310a或者330a和一个可动部分320a的开关同样在本发明的保护范围之内，因为虽然此时其不能切换两条不同的电路，但是其仍然有效地利用了插座内部空间，增加了插座中的开关从而使得插座在不增加体积的情况下能实现更多的功能，特别是和本发明先前描述的沿水平方向设置的触点开关(如20a-20d)共同配合使用时，该优点尤为明显。The movable part 320a has a fixed end 321a and a movable end 322a. When the plug 50 is not inserted into the channel 40, the movable part 320a contacts the fixed part 310a to form an electrical connection. At this time, the movable part 320a does not contact the fixed part 330a. When the plug 50 is inserted into the channel 40, the plug 50 pushes the movable end 322a to deflect to the left relative to the fixed end 321a, so that the movable part 320a is out of contact with the fixed part 310a and contacts with the fixed part 330a, forming another electrical connection; When the plug is pulled out of the channel 40, the movable end 322a loses the pushing force exerted by the plug and resets. Thereby it is realized that the switch 30a automatically switches between the two circuits as the plug 50 is inserted and pulled out. It should be understood that the switch 30 with two fixed parts 310a and 330a and one movable part 320a is an exemplary embodiment, which can switch two different circuits respectively, but only one The switch of the fixed part 310a or 330a and a movable part 320a is also within the scope of protection of the present invention, because although it cannot switch two different circuits at this time, it still effectively utilizes the inner space of the socket, increasing the The switch in the socket enables the socket to realize more functions without increasing the volume, especially when used together with the previously described contact switches (such as 20a-20d) arranged in the horizontal direction of the present invention, this advantage Especially obvious.
为了使插头50能更有效的切换开关30a，在活动末端322a处可以进一步设置朝向通道40伸出的延伸结构(或部件)323a。从而当插头50插入通道40后，插头50推动延伸结构(或部件)323a的末端325a向左移动。延伸结构(或部件)323a可以是如图5a和5b中所示的那样是在活动末端322a处弯折朝向通道40延伸所形成的结构，也可以是另外设置一个连接在活动末端322a处的部件形成，或者其它方式。设置延伸部件323a的好处至少在于能使开关更加的灵敏，在受到插头施加的推力的情况下能够有效的切换开关连接的电路，并且可动部件320a和通道40之间因此可以具有比较充裕的间隙，从而可以更方便灵活地设置不动部件310a以及设置可动部件320a的结构。In order to enable the plug 50 to switch the switch 30a more effectively, an extension structure (or part) 323a protruding toward the channel 40 may be further provided at the movable end 322a. Therefore, when the plug 50 is inserted into the channel 40, the plug 50 pushes the end 325a of the extension structure (or part) 323a to move to the left. The extension structure (or component) 323a can be a structure formed by bending and extending toward the channel 40 at the movable end 322a as shown in FIGS. formed, or otherwise. The advantage of setting the extension part 323a is at least that it can make the switch more sensitive, and can effectively switch the circuit connected by the switch under the push force applied by the plug, and there can be a relatively sufficient gap between the movable part 320a and the channel 40 , so that the fixed part 310a and the structure of the movable part 320a can be arranged more conveniently and flexibly.
可选的，可动部分320a在其长度方向上形成波形结构，波形结构诸如波峰326a和波谷327a，波峰326a朝向不动部分310a凸出，波谷327a朝向不动部分330a凸出。这样，随着插头50的插入和拔出通道40，波峰326a和波谷327a分别成为可动部分320a与不动部分310a和不动部分330a相接触的接触部分。波形结构的好处至少在于能使开关更加的灵敏，在受到插头施加的推力的情况下能够有效的切换开关连接的电路。图中所示的类似正弦和余弦的波形结构只是示例，波峰和波谷也可形成为其他形状。另外，如图中所示，朝向不动部分330a凸出的波谷327a比朝向不动部分310a凸出的波峰326a更靠近活动末端322a，这不仅确保当插头50插入到位而不是刚刚插入插座时就推动活动末端322a从而切换开关30，但是设置波峰326a比波谷327a更靠近活动末端322a也是可以的。Optionally, the movable portion 320a forms a wave structure along its length direction, such as crests 326a and troughs 327a, the crests 326a protruding toward the immovable portion 310a, and the troughs 327a protruding toward the immobile portion 330a. In this way, as the plug 50 is inserted and pulled out of the channel 40, the crests 326a and troughs 327a become the contact portions where the movable part 320a contacts the non-movable part 310a and the non-movable part 330a, respectively. The advantage of the waveform structure is at least that it can make the switch more sensitive, and can effectively switch the circuit connected to the switch under the condition of being pushed by the plug. The sine- and cosine-like waveform structures shown in the figure are just examples, and the peaks and troughs can also be formed in other shapes. In addition, as shown in the figure, the trough 327a that protrudes toward the stationary portion 330a is closer to the movable end 322a than the peak 326a that protrudes toward the stationary portion 310a, which not only ensures that the plug 50 will Pushing the movable end 322a toggles the switch 30, but it is also possible to locate the peak 326a closer to the movable end 322a than the valley 327a.
当本发明的插座具有如图2所示的四个沿水平方向设置的触点开关20a-20d以及二个沿垂直方向设置的触点开关30a和30b时，就可以替代图1a和图1b所示的插座和继电器的组合来实现两套多媒体播放设备的自动切换。图6是图2所示的插座实现两套多媒体播放设备的自动切换的接线示意图开关20a-20d每个开关的两个端子分别对应接线图中#4、#5，#2、#7，#8、#1，和#6、#3，开关30a中的可动部分320a和不可动部分310a、330a分别对应接线图中的A2，A1和A3，开关30b中的可动部分320b和不可动部分310b、330b分别对应接线图中的B2，B1和B3。同图1a一样，图6示意的是插头尚未插入插座2时各个开关的状态。此时插座开关20a-20d连接，故示意图中与之对应的开关#4、#5相连，#2、#7相连，#8、#1，#6、#3相连，插座开关30a和30b中可动部分320a和320b分别和各自的不动部分310a和310b连接，故示意图中与之对应的开关A1、A2相连，B1、B2相连。这样车内多媒体播放设备音频信号由⑦、⑧输入，①、②输出，视频信号由输入，⑨、⑩输出。同样虽然图6中没有显示，但是本领域技术人员应当理解，将移动多媒体设备输出端子(插头)插入插座后，随着插头的插入，开关20a-20d以及30a和30b的开关如上文所描述的进行转换，反映在示意图中即开关#4、#5断开，#2、#7断开，#8、#1断开，#6、#3断开，A2和A1断开而与A3相连，B2和B1断开而与B 3相连(与图1b相同)。这样移动设备要播放的音频信号直接通过①、②输出，视频信号直接通过⑩输出。When the socket of the present invention has four contact switches 20a-20d arranged in the horizontal direction and two contact switches 30a and 30b arranged in the vertical direction as shown in Figure 2, it can replace the contact switches shown in Figure 1a and Figure 1b. The combination of the socket and the relay shown in the figure can realize the automatic switching of two sets of multimedia playback equipment. Fig. 6 is the wiring schematic diagram that the socket shown in Fig. 2 realizes the automatic switching of two sets of multimedia playback devices. 8. #1, and #6, #3, the movable part 320a and the non-movable part 310a, 330a in the switch 30a respectively correspond to A2, A1 and A3 in the wiring diagram, and the movable part 320b and the non-movable part in the switch 30b Portions 310b, 330b correspond to B2, B1 and B3 in the wiring diagram, respectively. Same as FIG. 1a , FIG. 6 shows the state of each switch when the plug is not inserted into the socket 2 . At this time, the socket switches 20a-20d are connected, so the corresponding switches #4 and #5 are connected in the schematic diagram, #2 and #7 are connected, #8, #1, #6, and #3 are connected, and in the socket switches 30a and 30b The movable parts 320a and 320b are respectively connected to the respective fixed parts 310a and 310b, so the corresponding switches A1 and A2 are connected, and B1 and B2 are connected in the schematic diagram. In this way, the audio signal of the multimedia playback equipment in the car is input by ⑦, ⑧, output by ①, ②, and the video signal is output by Input, ⑨, ⑩ output. Also although it is not shown in Fig. 6, those skilled in the art should understand that after the output terminal (plug) of the mobile multimedia device is inserted into the socket, along with the insertion of the plug, the switches of the switches 20a-20d and 30a and 30b are as described above A switch is made, reflected in the schematic that switches #4, #5 are open, #2, #7 are open, #8, #1 are open, #6, #3 are open, A2 and A1 are open and connected to A3 , B2 and B1 are disconnected and connected with B3 (the same as in Figure 1b). In this way, the audio signal to be played by the mobile device is directly output through ① and ②, and the video signal is directly output through ⑩.
经过上述实施例的说明本领域技术人员完全理解，本发明插座的至少一个优点在于，其相对于现有技术充分利用了通道轴向上下左右四个方向上的空间来设置开关，其在上下两侧充分利用了通道轴向长度上的空间，而同时又在左右两侧又充分利用了通道径向宽度上的空间，并且通过开关端子的创新设计，使得上下两侧的开关端子和左右两侧的开关端子不仅能有机的结合，而且彼此之间对于开关的设置不会造成的影响。所以，上述布置4个沿水平设置的开关20a-20d以及2个沿垂直平方向设置的开关30a和30b的插座仅仅是本发明的一种具体实施例，只要在插座通道在通道上侧或下侧之一设置至少一个沿水平方向设置的触点开关和在通道左侧或右侧之一至少设置一个沿垂直方向设置的触点开关的插座都在发明的保护范围之内。比如，最少可以仅在通道上侧或下侧之一只设置一个沿水平方向设置的开关和在通道左侧或右侧之一只设置一个沿垂直方向设置的开关，又比如，可以同时在通道上下两侧设置数个沿水平方向设置的触点开关和左右两侧设置数个沿垂直方向设置的触点开关。开关的数量完全可以根据通道的长度，需要实现的功能、以及成本的考虑进行增减。Through the description of the above-mentioned embodiments, those skilled in the art fully understand that at least one advantage of the socket of the present invention is that, compared with the prior art, it makes full use of the space in the four directions of the channel axis, up, down, left, and right to set the switch. The side makes full use of the space on the axial length of the channel, and at the same time makes full use of the space on the radial width of the channel on the left and right sides, and through the innovative design of the switch terminal, the switch terminals on the upper and lower sides and the left and right sides The switch terminals can not only be combined organically, but also have no influence on the setting of the switch between each other. Therefore, the above-mentioned arrangement of four switches 20a-20d arranged horizontally and two switches 30a and 30b arranged vertically is only a specific embodiment of the present invention, as long as the outlet channel is on the upper or lower side of the channel. A socket provided with at least one contact switch arranged in the horizontal direction on one of the sides and at least one contact switch arranged in the vertical direction on one of the left or right sides of the channel is within the protection scope of the invention. For example, at least one switch arranged along the horizontal direction can only be arranged on one of the upper side or the lower side of the passage and only one switch arranged along the vertical direction can be arranged on one of the left side or the right side of the passage. Several contact switches arranged along the horizontal direction are arranged on the upper and lower sides, and several contact switches arranged along the vertical direction are arranged on the left and right sides. The number of switches can be increased or decreased according to the length of the channel, the functions to be realized, and cost considerations.
并且本发明插座中沿水平方向的触点开关和每个沿垂直方向设置的触点开关独特的结构和布置方式使得当设置多个触点开关时，每个沿水平方向的触点开关和每个沿垂直方向设置的触点开关各自都具有相同的结构成为可能，触点开关以及插座的制造成本(例如模具费用等)因此可以大大降低。And the unique structure and arrangement mode of the contact switch along the horizontal direction and each contact switch arranged in the vertical direction in the socket of the present invention make when a plurality of contact switches are set, each contact switch in the horizontal direction and each contact switch in the horizontal direction It is possible that each of the contact switches arranged in the vertical direction has the same structure, and the manufacturing cost of the contact switch and the socket (such as mold cost, etc.) can be greatly reduced.
图7是本发明插座的另一种实施例，图7中的插座2’和图2所显示的插座2的最主要区别在于，其不包括插座2中沿垂直方向设置触点开关，而只包括壳体3’，壳体3’具有用于容纳插头的通道40’，在通道40’的上方(也可以是下方)设置有多个(如4个)沿通道40轴向并列设置的水平方向触点开关20a’-20d’。每个触点开关20a’-20d’都具有相同的结构。Fig. 7 is another embodiment of the socket of the present invention, the main difference between the socket 2' in Fig. 7 and the socket 2 shown in Fig. Including the housing 3', the housing 3' has a channel 40' for accommodating plugs, and above (or below) the channel 40', a plurality (such as 4) of horizontal channels arranged side by side along the axial direction of the channel 40 are arranged. Directional contact switches 20a'-20d'. Each contact switch 20a'-20d' has the same structure.
触点开关20a’-20d’可以具有与触点开关20a-20d相似的结构。如图7所示的，触点开关20a’包括端子100a’和端子200a’，端子100a’和端子200a’各自都具有自由端和固定端；端子100a’和200a’分别具有在容纳插头插入的通道40’上方延伸的弹性臂120a’和220a’，弹性臂120a’从通道40’左方朝右方延伸，其末端延伸超过通道40a’并形成端子100a’的自由端；弹性臂220a’从通道40a’右方朝左方延伸，其末端延伸不超过通道40’并形成端子200a’的自由端。如图所示，弹性臂120a’和220a’具有重叠部分，在重叠部分弹性臂220a’在弹性臂120a’的下方；这样，当插头50未插入时，弹性臂120a’与弹性臂220a’相接触，当插头50插入时，插头50向上推动弹性臂120a’使其和弹性臂220a’脱离接触。The contact switches 20a'-20d' may have a structure similar to that of the contact switches 20a-20d. As shown in Figure 7, contact switch 20a' comprises terminal 100a' and terminal 200a', and terminal 100a' and terminal 200a' all have free end and fixed end respectively; The elastic arms 120a' and 220a' extending above the channel 40', the elastic arm 120a' extends from the left to the right of the channel 40', and its end extends beyond the channel 40a' and forms the free end of the terminal 100a'; the elastic arm 220a' extends from the channel 40' to the right. The channel 40a' extends rightwards and towards the left, the end of which extends no further than the channel 40' and forms the free end of the terminal 200a'. As shown, the elastic arms 120a' and 220a' have overlapping portions, and the elastic arm 220a' is below the elastic arm 120a' in the overlapping portion; contact, when the plug 50 is inserted, the plug 50 pushes the elastic arm 120a' upwards to disengage from the elastic arm 220a'.
同样，类似触点开关20a，在重叠部分，触点开关20a’中弹性臂220a’上具有向上凸出的凸起215a’，当然也可以设置弹性臂120a’使其在重叠部分具有向下突出凸起，这样当插头50未插入时，弹性臂120a’与220a’通过弹性臂上的凸起相接触。触点开关20a’的端子还可以具有其他与前述触点开关20a端子相同结构，所以触点开关20a’-20d’具有触点开关20a-20d的全部优点。Similarly, similar to the contact switch 20a, in the overlapping part, the elastic arm 220a' of the contact switch 20a' has an upwardly protruding protrusion 215a', of course, the elastic arm 120a' can also be set so that it has a downward protruding In this way, when the plug 50 is not inserted, the elastic arms 120a' and 220a' contact through the protrusions on the elastic arms. The terminal of the contact switch 20a' can also have the same structure as the terminal of the aforementioned contact switch 20a, so the contact switch 20a'-20d' has all the advantages of the contact switch 20a-20d.
插座2’的一种示例性应用是用作3.5mm的音频插座。此时作为音频插头的插头50没有插入时，每个开关都处于闭合状态，此时输出电信号指示没有探测到插头。插头50插入后，其和每个开关都接触向上推动每个开关的端子100a’-100d’，使得每个开关都打开，此时输出一个电信号指示检测到插头50插入，并且此时4个端子100a都和插头50连通，就可以实现四个电连接。在这个应用中，这4个端子100a’-100d’依次对应接地，左声道，右声道和麦克风，插头50沿其轴向从头部到根部对应这四个端子的部分也依次对应接地，左声道，右声道和麦克风，这样当插头50插入插座后，就实现了接地，立体声输出和麦克风输入的功能。所以上述插座能与标准的音频插头配合同时实现插头探测和立体声播放功能以及麦克风输入功能。An exemplary application of the jack 2' is as a 3.5mm audio jack. At this time, when the plug 50 as an audio plug is not inserted, each switch is in a closed state, and an electrical signal is output to indicate that no plug is detected. After the plug 50 is inserted, it is in contact with each switch and pushes up the terminals 100a'-100d' of each switch, so that each switch is turned on. At this time, an electrical signal is output to indicate that the plug 50 is inserted, and at this time 4 All the terminals 100a communicate with the plug 50, so four electrical connections can be realized. In this application, the four terminals 100a'-100d' correspond to grounding in turn, the left audio channel, the right audio channel and the microphone, and the part of the plug 50 corresponding to these four terminals along its axial direction from the head to the root is also correspondingly grounding in turn. , the left sound channel, the right sound channel and the microphone, so that when the plug 50 is inserted into the socket, the functions of grounding, stereo output and microphone input are realized. Therefore, the above-mentioned socket can cooperate with a standard audio plug to simultaneously realize the functions of plug detection, stereo playback and microphone input.
所以根据对触点开关20a’-20d’的描述，本领域技术人员应当理解插座2’同样具有非常良好的内部空间利用效率，可以在不增加插座体积的情况下，以实现其他更多的功能。而相对于实现相同功能的插座，本发明公开的插座使得插座设计更加的紧凑。并且其采用的触点开关结构简单，制造成本低。Therefore, according to the description of the contact switches 20a'-20d', those skilled in the art should understand that the socket 2' also has a very good internal space utilization efficiency, and can realize other more functions without increasing the volume of the socket. . Compared with the socket that realizes the same function, the socket disclosed by the present invention makes the design of the socket more compact. In addition, the contact switch adopted by it has a simple structure and low manufacturing cost.
尽管参考附图中示出的具体实施方式将对本发明进行描述，但是应当理解，在不背离本发明教导的精神和范围的情况下，本发明的插座还可以有许多变化形式。本发明中不同具体实施方式中的各个部件，在不违背本发明教导的精神的情况下，可以进行互换和重新组合，由此得到的插座同样落在本发明的保护范围内。本领域普通技术人员还将意识到有不同的方式来改变所公开的实施方式的参数，例如尺寸、形状、或元件或材料的类型，均落入本发明和权利要求的精神和范围内。Although the invention will be described with reference to specific embodiments shown in the drawings, it should be understood that many variations can be made to the socket of the invention without departing from the spirit and scope of the teachings of the invention. The components in different specific implementations of the present invention can be interchanged and reassembled without violating the spirit of the teaching of the present invention, and the socket thus obtained also falls within the protection scope of the present invention. Those of ordinary skill in the art will also appreciate that there are different ways of varying parameters of the disclosed embodiments, such as size, shape, or type of elements or materials, all within the spirit and scope of the invention and claims.
