Description

Computer motherboard with dual input/output interface ports

technical field

The utility model relates to a computer main board with double input/output interface ports, especially a main board with separate I/O interface ports on two opposite ends, which can reduce and simplify wiring by laying out circuit connections.

Background technique

With the rapid development and popularization of computer technology, the relationship between ordinary people and computers is getting closer. In this situation, the uses of computers are also becoming more diverse. In the past, computers were simple in purpose and their functions were relatively limited. Many multimedia devices were outside the In the early days, such as sound cards, display cards, etc., and network cards, etc. earlier, were all plugged into the motherboard in the form of adapter cards to expand these functions, and the interface ports formed by these adapter cards are It is concentrated on the back of the host case, and when it is connected to an external device such as a microphone, a speaker, or a modem, it is plugged in from the back of the host.

In recent years, the development technology of motherboards has also developed significantly. Many of the aforementioned functions have been changed from external to built-in, such as audio, network, video, etc. Users do not need to install sound cards, network cards, display cards, etc., that is, You can enjoy these functions. Although there is no need to install many adapter cards on the motherboard, input/output interface ports must still be provided for external peripheral devices. In order to make these interface ports more convenient to use, Announcement No. 531145 "Integration The input/output layout and assembly structure of the mainboard" new patent, the COM 1/COM 2 port connector, USB port connector, VGA port connector, PS/2 port connector, audio input/output port and other main The interface connector is integrated at one end of the motherboard, so that various devices can be connected to the motherboard at one place. And although the aforementioned patent application has integrated various interface connectors, they still remain at the rear end of the main board in the setting position, so in principle, most of the peripheral devices are connected by the back of the main board.

With the advent of high-speed transmission interfaces such as 1394 and USB, many traditional or new peripheral devices have adopted the aforementioned transmission protocols. As far as current motherboards are concerned, most of them support USB interfaces and are plug-and-play. There are many devices that can be connected with computers more conveniently, such as portable flash memory devices called flash drives TM on the market, network cameras, etc., because these devices are not often connected with computers, so they must have easy assembly and disassembly. Features, if it is plugged into the USB interface connector on the back of the host in the traditional way, no matter whether it is plugged or unplugged, it is very inconvenient to operate. And of course the industry is very sensitive to this demand, so some commonly used interface connectors are also arranged on the front side of newly listed computer hosts. As shown in Figure 3, there is an existing computer mainframe (70) disclosed, which is provided with interface connectors (not shown in the figure) in addition to the back, and some interface connectors are also provided on the lower edge of the front, including the most commonly used 1394 connector (71), USB interface connector (72), sound input socket (73), sound output socket (74), optical fiber connector (75) and so on. In this way, the user can directly plug in devices using USB interfaces such as flash drives and network cameras, or microphones, earphones, etc. from the front of the host computer (70) very conveniently.

There is no doubt about the convenience of setting some interface connectors on the front of the host as mentioned above, but the existing standard motherboards only have interface ports at the rear end, and there is no interface port configuration at the front end. The corresponding method to meet the aforementioned requirements is As shown in Figures 4 and 5, in addition to the interface ports (81) formed by various interface connectors on the rear end of the general motherboard (80), there are also corresponding sockets (82)-( 85), for additional interface connectors. Therefore, the mode of adding an interface connector on the front of the mainframe at present is to add an additional 1394 connector (71), a USB interface connector (72), a sound input socket (73), a sound output socket (74), and an optical fiber connector. (75) etc. are first located on a circuit board (700), and then are respectively connected with sockets (82)～(85) on the main board (80) by wires (801)～(804), so that the circuit board 1394 connector (71), USB interface connector (72), sound input socket (73), sound output socket (74), optical fiber connector (75) etc. on (700) can be installed on main computer (70) ) on the front.

But the foregoing method obviously has shortcomings, and the reason is that the original wiring on the mainboard (80) is very complicated, such as hard disks, optical drives, burners, disk drives, etc. must be connected with the mainboard (80) by cables, Another example is that the main board (80) must also supply the power supply of the CPU heat sink by wires. If the additional wires (801)～(804) added between the circuit board (700) and the main board (80) will make the wiring The complex situation is exacerbated.

It can be seen from the above that it is the general trend to install some interface connectors on the front of the host. However, because the current motherboard does not support it, it can only be implemented in a compromise manner, but it will make the already complicated wiring on the motherboard even more complicated. Further review and seek possible solutions.

Contents of the invention

Therefore, the main purpose of this utility model is to provide a kind of I/O interface port on the opposite two ends separately and connect through layout circuit, so that reduce and simplify the motherboard of wiring.

The main technical means taken to achieve the aforementioned purpose is to make the aforementioned mainboard be provided with a first I/O interface port at one end and a second I/O interface port at the opposite end, which are respectively composed of a plurality of interface connectors , which are connected to each other through the lines on the main board, and connected to the corresponding interface circuit set on the main board;

When the above-mentioned motherboard with first/second I/O interface ports at opposite ends is installed in the casing, the first/second I/O interface ports are respectively located on the back and the front of the casing respectively. Both the front and the back of the host have commonly used interface connectors to facilitate the connection of peripheral devices.

The aforementioned first/second I/O interface ports are composed of a plurality of interface connectors, and the second I/O interface ports corresponding to the front of the motherboard include at least one set of USB interface connectors.
