电脑用的外接式接口装置External interface device for computer

本实用新型涉及一种用作电脑主机板和外接式周边设备的电源与讯号传输的接口装置。The utility model relates to an interface device used for power supply and signal transmission of a computer mainboard and external peripheral equipment.

目前，随着科技及经济的快速发展，电脑已成为企业、家庭或个人在日常工作或生活上不可缺少的设备之一。当今的电脑类型也很多，有高级，有简易，有大尺寸的又有微型的，可以在办公室、家庭、会议室、实验室、宾馆、汽车、飞机上使用，这足以说明电脑的迅猛发展，但是更重要的是电脑从科学计算、绘图、文字处理，变成了具有可将文字、声音、影像加以数字化，予以处理和储存，并传送到世界每一角落的多媒体以及通讯功能。也正是由于电脑的功能愈来愈巨大，电脑所处理的信息量也愈来愈巨大，对应付这种巨大的交互式信息量，一般最常见的硬件升级手段之一，就是增添或使用各种较新的储存媒体，如光碟机、高容量硬碟、高容量光学式软碟等。使用的方式，又以外接式最为直接而方便，除了原有的设备仍可使用外，也无需不时拆卸电脑，对于一般使用者来说最为简便。At present, with the rapid development of science and technology and economy, computers have become one of the indispensable devices in daily work or life of enterprises, families or individuals. There are also many types of computers today, including advanced, simple, large and miniature, which can be used in offices, homes, conference rooms, laboratories, hotels, cars, and airplanes. This is enough to illustrate the rapid development of computers. But more importantly, computers have changed from scientific computing, drawing, and word processing to multimedia and communication functions that can digitize text, sound, and images, process and store them, and transmit them to every corner of the world. It is precisely because the functions of computers are becoming more and more powerful, and the amount of information processed by computers is also increasing. To cope with this huge amount of interactive information, one of the most common hardware upgrade methods is to add or use various A newer storage medium, such as optical disc drive, high-capacity hard disk, high-capacity optical floppy disk, etc. The way to use it is the most direct and convenient external type. In addition to the original equipment can still be used, there is no need to disassemble the computer from time to time, which is the most convenient for ordinary users.

目前电脑资料信息的传送接口，主要有两种，即SCSI(小型计算机通用接口)及IDE(主机内部硬盘接口)，其中SCSI接口的读取或存储设备通常比较贵，使用起来也较麻烦，因此使用量较少，而最普及的接口还是IDE接口。At present, there are mainly two types of transmission interfaces for computer data information, namely SCSI (Small Computer Universal Interface) and IDE (Internal Hard Disk Interface of the Host). The usage is less, and the most popular interface is the IDE interface.

目前一般所使用的外接式电脑周边设备，如外接式硬碟，外接式唯读光碟机等，都是将硬碟或唯读光碟机装于一外接盒内，并以传输线连接在位于电脑上的并列埠(Parallel Port)上，通过该并列埠和电脑沟通。使用这种外接盒的优点是：可携性高，很容易和任何一台电脑连线，因为并列埠是个人电脑(PC)的标准接口之一，每一台电脑都至少有一个并列埠(最常使用并列埠的就是打印机)。使用并列埠接口传送信息速度较慢，不适合传送大量信息，也会出现信息传送的失误(Data Loss)。还有必须加挂特殊的驱动程序，才可和电脑沟通。通常还须有特殊硬件来处理信息的传送，这说明，所有外接盒必须有一特殊的IC来担负这一工作。使用外接式设备，都必须同时提供电力，为此，几乎所有外接盒都另外加装一电源供应器。这样看来使用并列埠在技术上看效率是很低的。External computer peripherals commonly used at present, such as external hard disks, external CD-ROMs, etc., are installed in an external box with the hard disk or CD-ROM, and connected to the computer with a transmission line. On the parallel port (Parallel Port), communicate with the computer through the parallel port. The advantage of using this external box is: high portability, easy to connect with any computer, because the parallel port is one of the standard interfaces of personal computers (PC), and each computer has at least one parallel port ( The most commonly used parallel ports are printers). Using the parallel port interface to transmit information is slow, and it is not suitable for transmitting large amounts of information, and information transmission errors (Data Loss) will also occur. Also, a special driver must be added to communicate with the computer. Usually there must be special hardware to handle the transfer of information, which means that all external boxes must have a special IC to do this job. When using external devices, power must be provided at the same time. For this reason, almost all external boxes are additionally equipped with a power supply. It seems that using parallel port is technically inefficient.

针对上述情况，电脑使用技术要求的提高，既考虑信息交流的速率，制造成本的降低，又要考虑使用环境的巨大变化，应配合电脑有关技术原理，提出最好的解决方案以满足目前电脑使用者的实际需求。In response to the above situation, the improvement of computer use technology requirements not only considers the speed of information exchange, the reduction of manufacturing costs, but also considers the huge changes in the use environment. It should cooperate with the relevant computer technology principles to propose the best solution to meet the current computer use. the actual needs of the recipient.

本实用新型的目的在于针对上述情况，提供一种电脑用的外接式接口装置，可将位于电脑主机板上的传输接口(IDE或SCSI接口)转换成外接式接口装置，并通过一传输排线直接连接使用各种外接式的电脑周边设备，可不需额外加装集成电路及驱动程序，即直接驱动该外接式周边设备。可直接将电路设计安排在电脑主机板上，并且还可自动侦测电脑主机板上各个IDE接口槽的使用状况，并自动将接口装置插槽切换连接至适当的主机板上的IDE接口上。该外接式接口装置还可藉由传输线上多余的线路充当电源线，将电脑主机内的电源的电流直接供应外接周边设备，使这类外接式接口装置适用于笔记本类型电脑。The purpose of this utility model is to provide an external interface device for a computer, which can convert the transmission interface (IDE or SCSI interface) on the motherboard of the computer into an external interface device, and pass a transmission cable Directly connect and use various external computer peripheral devices, which can directly drive the external peripheral devices without installing additional integrated circuits and drivers. The circuit design can be directly arranged on the computer motherboard, and the usage status of each IDE interface slot on the computer motherboard can be automatically detected, and the interface device slot can be automatically switched and connected to the appropriate IDE interface on the motherboard. The external interface device can also directly supply the current of the power supply in the host computer to the external peripheral devices by using the extra line on the transmission line as a power line, so that this type of external interface device is suitable for notebook computers.

下面结合附图和实施例作进一步说明：Below in conjunction with accompanying drawing and embodiment for further explanation:

由图1可见，为本实用新型第一实施例，是利用一外接式接口40来作为电脑主机板20和外接式IDE周边配备30的IDE讯号与电源的传输接口。其中该电脑主机板20具有一电源座22(其连接于一图中未示的电源供应器)以及至少一个IDE接口槽25(即IDE-Slot，一般的主机板多具有两个IDE接口槽，其分别称为IDE-Slot1及IDE-Slot2)以分别用来传输电源和IDE讯号。As can be seen from FIG. 1 , it is the first embodiment of the present utility model, which uses anexternal interface 40 as the transmission interface of the IDE signal and power supply of thecomputer motherboard 20 and the external IDEperipheral equipment 30 . Wherein thecomputer motherboard 20 has a power base 22 (which is connected to a power supply not shown in the figure) and at least one IDE interface slot 25 (i.e. IDE-Slot, the general motherboard has two IDE interface slots at most, They are respectively called IDE-Slot1 and IDE-Slot2) and are used to transmit power and IDE signals respectively.

该外接式接口40设有包括一插槽41，其一般可为具有五十针(Pin)的SCSI插槽为较佳，故以下的说明将以SCSI插槽41为例，当然也可由任何具有四十二针以上的各式插槽所替代。该括槽41经由一接口排线43(其可为一SCSI排线或任何具有四十二针以上的排线)连接于电脑主机板20上所增设的一接口插槽26(其可为一SCSI插槽)。于电脑主机板20上设有一控制晶片27，藉由设计于电脑主机板20上的电路设计，可将接口插槽26的其中四十针耦合连接于该控制晶片27，并经由控制晶片27同时耦合连接于电脑主机板20上的各个IDE接口槽25。藉由该控制晶片27可控制插槽41上用来传输资讯的针与该各个IDE接口槽25中的其中之一，且唯一的一个IDE接口槽25耦合连接(即不会同时连接两个)，以进行IDE讯号的传输。并且，该控制晶片27中包含有一控制逻辑，可自动侦测电脑主机板20上各个IDE接口槽25的使用状况，并自动将接口插槽26切换连接到适当的IDE接口槽25上。例如，当控制晶片27侦测到电脑主机板20上的IDE-Slot1还可连接一IDE装置时，该控制晶片27即会把接口插槽26连接到IDE-Slot1上；而当控制晶片27侦测到电脑主机板20上的IDE-Slot1已满且IDE-Slot2尚有空位时，其即自动把接口插槽26连接到IDE-Slot2上；而当控制晶片27侦测到电脑主机板20上的所有IDE插槽均已接满时，则会自动将接口插槽26断路以避免冲突现象的发生。当然，也可在电脑主机板20上增设一开关(图6未示)以手动的方式、或是以软件控制的方式进行接口插槽26与IDE-Slot1及IDE-Slot2间的切换连接。此外，接口插槽26中至少有两针以上连接耦合至该电源座22上，以便将电脑主机板20上的电源经由接口排线43供应至插槽41。也可将接口插槽26中用以传输电源的针经由该电路设计而连接在控制晶片27上，以受控制晶片27的控制来决定电源的供应与否。再者，于电脑主机板20上的电路设计中可增设包括一电流缓冲单元与讯号放大单元(图中未示)以保护电路并增强讯号。Thisexternal interface 40 is provided with and comprises aslot 41, and it generally can be to have the SCSI slot of 50 pins (Pin) to be better, so following description will be example withSCSI slot 41, certainly also can be by any All kinds of sockets with more than forty-two pins are replaced. Thebracket 41 is connected to anadditional interface slot 26 on the computer motherboard 20 (it can be a SCSI cable or any cable with more than forty-two pins) via an interface cable 43 (it can be a SCSI cable). SCSI slot). Acontrol chip 27 is provided on the computermain board 20. By designing the circuit design on the computermain board 20, the forty pins of theinterface slot 26 can be coupled and connected to thecontrol chip 27, and can be connected to thecontrol chip 27 simultaneously. It is coupled to eachIDE interface slot 25 on thecomputer motherboard 20 . The pin used to transmit information on theslot 41 can be controlled by thecontrol chip 27 to one of theIDE interface slots 25, and the only oneIDE interface slot 25 is coupled (that is, not connected to two at the same time) , for IDE signal transmission. Moreover, thecontrol chip 27 includes a control logic, which can automatically detect the usage status of eachIDE interface slot 25 on thecomputer motherboard 20, and automatically switch theinterface slot 26 to be connected to the appropriateIDE interface slot 25. For example, when thecontrol chip 27 detects that the IDE-Slot1 on thecomputer motherboard 20 can also connect an IDE device, thecontrol chip 27 will connect theinterface slot 26 to the IDE-Slot1; When detecting that the IDE-Slot1 on thecomputer motherboard 20 is full and IDE-Slot2 still has a vacancy, it automatically connects theinterface slot 26 to the IDE-Slot2; When all the IDE slots are fully connected, theinterface slot 26 will be automatically disconnected to avoid conflicts. Of course, a switch (not shown in FIG. 6 ) can also be added on the mainboard of thecomputer 20 to switch between theinterface slot 26 and the IDE-Slot1 and IDE-Slot2 manually or in a software-controlled manner. In addition, at least two or more pins in theinterface slot 26 are coupled to thepower base 22 so as to supply the power on thecomputer motherboard 20 to theslot 41 via theinterface cable 43 . The pins for power transmission in theinterface slot 26 can also be connected to thecontrol chip 27 through the circuit design, so as to be controlled by thecontrol chip 27 to determine whether the power is supplied or not. Moreover, a current buffer unit and a signal amplifying unit (not shown in the figure) can be added in the circuit design on thecomputer motherboard 20 to protect the circuit and enhance the signal.

由图1还可见，该外接式IDE周边配备30由一排线47(其可为一SCSI排线为较佳，故以下的说明将以SCSI排线47为例)插置于外接式IDE周边配备30与该插槽41之间以作为同时传输IDE讯号以及电源的媒介。本实用新型的外接式IDE周边配备30的一较佳实施例包括有：一壳体31及一容置于该壳体31内的IDE周边36(其可为一采用IDE接口的硬碟、光碟机或是磁带机等)。于壳体31上设有一周边SCSI插槽32以插置该SCSI排线47。该周边SCSI插槽32的各个针连接到一周边电路板33上，并藉由周边电路板33上的电路设计，将周边SCSI插槽32的各个针中用来传输讯号的针连接在一固定在周边电路板33上的周边传输埠34上(其可为一IDE埠为较佳)，并同时将周边SCSI插槽32中用来传输电源的针连接于一固定于周边电路板33上的周边电源埠35。当将该IDE周边36括置入壳体31内时，该IDE周边36上的讯号接头与电源接头恰可分别插置并定位于该周边传输埠34与周边电源埠35上，因此，电脑主机板20上的IDE讯号及电源，便可藉由该外接式接口40提供到外接式IDE周边配备30上，不仅该外接式周边不需另行配置额外的直流电源供应器(例如变压器)，还可避免使用昂贵的SCSI周边来外接，或是缓慢的并列埠来传送资料。当然，以上所述仅为本实用新型的一较佳实施例，而并非是唯一的可实施例，而在该外接式IDE周边配备30的壳体31上增设置一电源孔(图中未示)连接在周边电路板33上，并在周边电路板33上增设有开关(图中未示)，使用者便可用该开关的切换来选择使用经由电源孔插接一额外的直流变压器来提供电源，或是使用经由排线47所传输的电脑主机板20上的电源。此外，还可将该排线47设计成具有分接头的排线(图中未示)，而使该排线可同时连接两台外接式IDE周边配备30。It can also be seen from FIG. 1 that the external IDEperipheral equipment 30 is inserted into the external IDE peripheral by a cable 47 (it is preferably a SCSI cable, so the following description will take theSCSI cable 47 as an example) Between thedevice 30 and theslot 41 is used as a medium for simultaneously transmitting IDE signals and power. A preferred embodiment of the external IDEperipheral equipment 30 of the present utility model includes: acasing 31 and an IDE peripheral 36 accommodated in the casing 31 (it can be a hard disk or optical disk using an IDE interface drive or tape drive, etc.). Aperipheral SCSI slot 32 is disposed on thecasing 31 for inserting theSCSI cable 47 . Each pin of theperipheral SCSI slot 32 is connected to aperipheral circuit board 33, and by the circuit design on theperipheral circuit board 33, the pins used for transmitting signals in each pin of theperipheral SCSI slot 32 are connected to a fixed pin. On theperipheral transmission port 34 on the peripheral circuit board 33 (it can be an IDE port is better), and simultaneously the pin that is used for transmitting power in theperipheral SCSI slot 32 is connected to a pin that is fixed on theperipheral circuit board 33Peripheral Power Port 35. When the IDE peripheral 36 is included in thecasing 31, the signal connector and the power connector on the IDE peripheral 36 can be respectively inserted and positioned on theperipheral transmission port 34 and theperipheral power port 35. Therefore, the computer host The IDE signal and power on theboard 20 can be provided to the external IDEperipheral equipment 30 through theexternal interface 40, not only the external peripheral does not need to be additionally equipped with an additional DC power supply (such as a transformer), but also Avoid using expensive SCSI peripherals for external connections, or slow parallel ports for data transfer. Of course, the above description is only a preferred embodiment of the present utility model, but not the only possible embodiment, and a power hole (not shown in the figure) is added on thehousing 31 of the external IDE peripheral equipment 30 ) is connected to theperipheral circuit board 33, and a switch (not shown) is added on theperipheral circuit board 33, and the user can use the switching of the switch to choose to use an additional DC transformer plugged through the power hole to provide power , or use the power on thecomputer motherboard 20 transmitted via thecable 47 . In addition, theflat cable 47 can also be designed as a flat cable with taps (not shown in the figure), so that the flat cable can be connected to two external IDEperipheral devices 30 at the same time.

由图2可见，为本实用新型第二实施例，可适用于一般主机板或是笔记本型电脑的电脑主机板20a上。由于简易型电脑或笔记本型电脑具有内部空间狭小的限制，因此，如何能将本实用新型的外接式接口40的空间占用更进一步缩小，是本实用新型能适用于简易型电脑或笔记本型电脑上的重点，至于笔记本型电脑的其它公知元件例如外壳结构或其它插槽等，由于不是本实用新型的特征，故在此不予赘述。图2所示的实施例中，主要是将插槽41a直接设置在电脑主机板20a上以免除图1中的接口排线43的使用，而其设置的方式，可将插槽41a直接焊接耦合在电脑主机板20a上，或是在电脑主机板20a上设置一插座(图中未示)以直接插置该插槽41a。如前所述，电脑主机板20a上也具有一电源座22a、两个IIE接口槽25a、一具有控制逻辑的控制晶片27a以及一电流缓冲与讯号放大单元28，并由电脑主机板20a上的一适当的电路设计来连接耦合上述各元件。于电脑主机板20a的电路设计上可设置包括有至少一组开关48及LED指示灯49。该开关48可用来切换插槽41a，使其切换连接于两个LDE接口槽25a的其中之一，且LED指示灯49可用来指示电源的供应状况。当然，可在电脑主机板20a上增设另一组开关(图中未示)以控制电源的供应，或是让控制晶片27a来自动判断以决定并控制插槽41a是与哪一个IED接口槽25a连接。It can be seen from FIG. 2 that it is the second embodiment of the present invention, which can be applied to a general motherboard or a computer motherboard 20a of a notebook computer. Since the simple computer or the notebook computer has the limitation of the narrow and small internal space, how to further reduce the space occupation of theexternal interface 40 of the present utility model is that the utility model can be applied to the simple computer or the notebook computer. As for the other known elements of the notebook computer, such as the shell structure or other slots, etc., since they are not the features of the present invention, they will not be described in detail here. In the embodiment shown in Fig. 2, the slot 41a is mainly arranged directly on the computer motherboard 20a so as to avoid the use of theinterface cable 43 in Fig. On the computer motherboard 20a, or a socket (not shown) is provided on the computer motherboard 20a to be directly inserted into the slot 41a. As previously mentioned, the computer motherboard 20a also has a power socket 22a, two IIE interface slots 25a, a control chip 27a with control logic, and a current buffer andsignal amplifying unit 28, and is controlled by the computer motherboard 20a. An appropriate circuit design is used to connect and couple the above-mentioned components. At least one set of switches 48 and LED indicator lights 49 may be provided on the circuit design of the computer motherboard 20a. The switch 48 can be used to switch the slot 41a so that it is switched to be connected to one of the two LDE interface slots 25a, and theLED indicator 49 can be used to indicate the power supply status. Of course, another set of switches (not shown) can be added on the computer motherboard 20a to control the power supply, or the control chip 27a can automatically judge to determine and control which IED interface slot 25a the slot 41a is connected to. connect.

由图3可见，为本实用新型的第三实施例，可同时适用于IDE或SCSI的外接式周边设备。图3中所示的外接式接口的构造大体上与图2中所示实施例相同，也包括有一直接设置于电脑主机板20b上的插槽41b，且电脑主机板20b上也具有一电源座22b、两个IDE接口槽25b、一具有控制逻辑的控制晶片27b、一电流缓冲与讯号放大单元28b、至少一组开关48b以及至少一组LED指示灯49b。其不同的是，若以一SCSI插槽为例，由于一般SCSI插槽所具有的五十支针并非全部都会被用来传输讯号，而仍会余下部分的针闲置不用，所以，在此实施例中，于电脑主机板20b上更包括有一内建的SCSI接口槽29，且该插槽41b(于本实施例中该插槽41b为一SCSI插槽)大部分的针(或全部针)是藉由电脑主机板20b上的电路设计来连接耦合于该控制晶片27b，然后再经由控制晶片27b连接耦合于该两IDE接口槽25b及SCSI接口槽29。藉由该控制晶片27b(也可藉由电脑主机板20b上的BIOS或是作业系统)来自动侦测该插槽41b所外接的周边设备究竟是采用IDE接口还是SCSI接口，并自动切换使插槽41b的各个针连接耦合在适当的IDE接口槽25b或是SCSI接口槽29上。当然，在该开关48b上也可增设一切换选择(或也可另设一开关)让使用者可以手动的方式自行决定并控制插槽41b的针是与哪一个IDE接口槽25b或是SCSI接口槽29连接。当然，可使图3中的插槽41b仅连接在SCSI接口槽29上而不连接在IDE接口槽25b，而让该插槽41b只适用于外接式SCSI周边设备。这样，就可将本实用新型的适用范围由外接式IDE周边设备扩展到外接式SCSI周边设备上，甚至两者均可使用。It can be seen from FIG. 3 that it is the third embodiment of the present invention, which is applicable to both IDE and SCSI external peripheral devices. The structure of the external interface shown in Fig. 3 is substantially the same as that of the embodiment shown in Fig. 2, and also includes a slot 41b directly arranged on the computer motherboard 20b, and the computer motherboard 20b also has a power socket 22b, two IDE interface slots 25b, a control chip 27b with control logic, a current buffer and signal amplifying unit 28b, at least one set of switches 48b and at least one set of LED indicator lights 49b. The difference is that if a SCSI slot is taken as an example, not all of the fifty pins in a general SCSI slot will be used to transmit signals, and the rest of the pins will still be idle. In an example, a built-inSCSI interface slot 29 is further included on the computer motherboard 20b, and most of the pins (or all pins) of the slot 41b (the slot 41b is a SCSI slot in this embodiment) It is connected and coupled to the control chip 27b by the circuit design on the computer motherboard 20b, and then connected and coupled to the two IDE interface slots 25b and theSCSI interface slot 29 via the control chip 27b. By this control chip 27b (also can be by the BIOS or the operating system on the computer motherboard 20b) automatically detect whether the peripheral equipment connected to the slot 41b adopts the IDE interface or the SCSI interface, and automatically switch to make the plug-in Each pin connection of slot 41b is coupled to the appropriate IDE interface slot 25b orSCSI interface slot 29 . Of course, a switching option (or another switch) can also be added on the switch 48b so that the user can manually decide and control which IDE interface slot 25b or SCSI interface the pin of the slot 41b is connected to.Groove 29 connection. Of course, the slot 41b in FIG. 3 can only be connected to theSCSI interface slot 29 instead of the IDE interface slot 25b, and the slot 41b is only suitable for external SCSI peripheral devices. In this way, the scope of application of the present invention can be extended from the external IDE peripheral device to the external SCSI peripheral device, and even both can be used.
