Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector connection structure between electronic devices.

[Conventional technology]

Conventionally, in the connection structure between multiple electronic devices, for example, the connector connection structure between a host computer and a printer connects each device with a relay cable, or the board mounting hole is made large (dumb hole) and the host computer is connected to the printer. It was common practice to force the connection and to compensate for the lateral misalignment between the host computer board and the printer connector board with a hole, or to connect them by shifting them from the printer body.

[Problem that the invention attempts to solve]

However, in the conventional connection structure between multiple electronic devices, for example, the connector connection structure between a host computer and a printer is not suitable for relay cable connection in response to the diversifying needs of recent computer systems such as handheld and miniaturization. It is difficult to respond immediately, and there is no flexibility in dealing with the horizontal center misalignment between the host computer side board and the printer side connector board, resulting in problems such as connection failures, and handle-held devices because the printer is connected in a misaligned state. The disadvantage of this type was that the sides of the host computer and printer were not flush, resulting in an unsatisfactory appearance. SUMMARY OF THE INVENTION It is an object of the present invention to provide a structure for connecting electronic devices to each other, which eliminates these drawbacks of the conventional devices, is compatible with hand-held design and miniaturization, and is free from problems such as connection failures.

[Means for solving problems]

In order to solve the above problems, the present invention has connectors on the rear side of a first electronic device and the front side of a second electronic device, and connects the connectors to exchange signals, thereby creating a system. A connector board provided with a groove or an elongated hole having a long axis in this direction in a direction substantially perpendicular to the connector attachment/detachment direction, a roller shaft provided in a case of an electronic device, and this roller shaft. and a guide roller rotatably supported by the connector board and slidably inserted into the groove or elongated hole of the connector board, and the connector board and the connector are fixed to each other and installed in the first or second electronic device. It is characterized by the fact that

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings based on a connector connection structure between a host computer and a printer.

FIG. 1 is a top view generally showing the connector connection structure between a host computer and a printer.

FIG. 2 is a cross-sectional view of the AOA′ of FIG. 1, and is a detailed cross-sectional view of the guide roller part and the board fixing part.

Reference numeral 1 denotes a host computer main body, and a board 2 for transmitting and receiving signals is fixed to the computer main body with fixing screws 3. Further, the board 2 has a card edge part 2a which is connected and inserted into a connector on the printer side, and is guided and protected by a shell connector 4 covering the card edge part 2a. This shell connector 4 generally has a tapered insertion surface with the connector 14 on the printer side, and has a tip guide portion 4a.
Since it has an R shape, the connector board 1 on the printer side, which will be described later, will prevent center deviation between the connectors.
This produces lateral forces as indicated by arrows C and D in Figure 2. A roller shaft 16 molded from the printer body 10 on the printer side is fixed, and left and right rollers rotate in response to the connector board 12 that moves in the left and right directions of arrows C and D, which are supported by the roller shaft 16. There is a guide roller 15. The connector board 12 is fixed to the front side of the printer main body 10 by being connected to the connector 14 by pattern wiring or the like. A common method is sufficient for this connection and fixing. In addition, the connector board 12 has cutout portions 12a that engage with the guide rollers 15 described above and are arranged on the left and right sides with the connector 14 sandwiched therebetween. In this embodiment, there are a plurality of guide rollers 1, two on the left and right, but the connector board 12 can move in parallel to the left and right as shown by arrows C and D.
5 and a notch 12a may be provided. If the guide roller 15 is placed as far away from the center of the connector in the left-right direction as possible, rotation due to the rotating part of the guide roller 15 of the connector board 12 and play between the guide roller 15 and the notch 12a can be avoided. It is effective against The flexible cable 13 connects the control board 21 fixed to the printer body 10 with fixing screws 22 and the connector board 12, so that signals can be reliably exchanged even when the connector board 12 moves as shown by arrows C and D. This is the structure that takes place. As shown in FIG. 2, the connector board 12 is fixed to the printer main body 10 with a fixing screw 19 with a slight clearance t provided by a flat washer 18 to prevent it from coming off the guide roller 15. Naturally, since the connector board 12 moves laterally, it forms a large escape hole in the lateral direction. At the rear of the connector board 12, a connection connector 11 for connection with other expansion bases is connected to the board of the host computer 1 and the shell connector 4.
It is fixed in the same way as the connection. In other words, if the expansion base is equipped with the printer connector connection structure of the present invention, it can be connected continuously.

The guide roller 15 also has a press-fit bush 20 press-fitted onto the roller shaft to prevent it from coming off. This prevention of slippage can also be sufficiently achieved by other common means such as a retaining ring.

The board holding guide 17 is raised from the bottom of the printer 10 and holds the connector board 12, and has a simple structure that simply slides on the holding guide surface when the connector board 12 moves in the lateral direction.

To connect a host computer and a printer, the connectors may be connected by facing each other and moving the case body in parallel, or by rotating the printer or computer side using one end of the case body as a fulcrum. It can also be connected. In any case, as mentioned above, arrows C and D
Any connection will suffice as long as it generates a force on either side. With this type of connection, the connector board inside the printer can be moved to ensure a secure connection.

[Effect of idea]

As described above, according to the present invention, a connector board is provided with a groove or an elongated hole having a long axis in a direction substantially perpendicular to the connector attachment/detachment direction, and a roller shaft provided in a case of an electronic device. , a guide roller rotatably supported by a roller shaft and slidably inserted into a groove or slot of the connector board, and the connector board and the connector are fixed and installed in the first or second electronic device. Therefore, the connector board can be moved in parallel with a low load by the guide roller, and there is a center misalignment between the connector of one electronic device and the connector of the other electronic device in a direction approximately perpendicular to the connection/detachment direction. Even when the connector board is rotated by the guide roller, the connector board moves in parallel without any force, absorbing the center deviation, and connecting the connectors without causing problems such as poor connection. is fixed, so the boards can be directly connected to each other.
Electronic equipment can be made handheld and smaller without creating wasted space.

Furthermore, since positioning can be performed based on the external shapes of both electronic devices, the external appearance can be improved.
