Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information device, and more particularly to a device for holding an expansion board.

[0002]

2. Description of the Related Art In an information device such as a word processor or a personal computer, an expansion board may be connected to a main board provided in a main body to expand the function. As shown in FIG. 5, the extension board 3 is provided with connectors 7 and 8 on both sides, and the connector 7 on one side is inserted and fitted into the connector 6 provided on the main board 1 by pin coupling, while the other end is connected to the other end. On the provided connector,
The connector 8 attached to the cable 9 connected to another machine is inserted and fitted by pin coupling. When trying to remove the cable 9 from the extension board 3, the extension board 3 is held on the main board 1 only by the pin connection of the connectors 6 and 7, so that the connector 8 of the cable 9 does not come off and the extension board 3 does not come off. There was a problem that 3 was dropped from the main substrate 1.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and when pulling out the cable connector from the expansion board and applying pulling force to the cable, the expansion board comes out from the main body side. The present invention is to provide a substrate holding device that can insert and remove the expansion board by a simple procedure when it is desired to remove the expansion board without causing it to be removed.

[0004]

In order to solve the above problems, the present invention provides a main board having an insertion opening provided in a main body and a connector provided in the main body facing the insertion opening, Front and rear rails are vertically provided on both side surfaces facing each other, a holding body provided on the back surface of the main body with a locking portion formed on one rail, and a connector corresponding to the connector of the main board, An expansion board guided in the guide groove between the rails, one end fixed to both sides of the upper surface of the expansion board, the other end of which can be deformed inwardly, and an outside locking claw corresponding to the locking portion of the holding body. It is characterized in that it comprises a formed stopper, and both sides of the extension board are inserted into the guide groove of the holding body at the time of mounting, and the locking claw is engaged with the locking portion.

[0005]

With the above construction, in the board holding device according to the present invention, when the cable connector is to be pulled out from the expansion board, the expansion board holds the locking claws provided on the board holder. With this, it is possible to prevent the problem that the expansion board is accidentally disengaged, and when the expansion board is removed from the main board, the expansion board can be easily removed by removing the locking claw.

[0006]

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a view showing an information device 1 such as a word processor and a personal computer. The information device 1 is provided with an insertion port 1b for an expansion board 3 on the rear or side of the main body.
The expansion board 3 connected to another information device via the cable 9 is inserted into the b.

As shown in FIG. 2, the extension board 3 is a connector 3
The substrate 3a, on which c and 3g are arranged, is screwed and fixed to the stopper 3b. The stopper 3b made of synthetic resin and formed in a U shape forms a lever portion 3d by bending a U-shaped tip end into a stepped shape, and provides bosses 3e on both inner sides thereof. A screw hole 3f is provided. Triangular locking claws 3h are provided on both outer sides. The substrate 3a is fixed below the stopper 3b, and is fixed to the stopper 3 by inserting a screw into a screw insertion hole provided in the substrate and screwing the screw into the screw hole 3f of the stopper.

As shown in FIG. 3, a rectangular insertion hole 1b is provided in the mounting portion 1a of the device body 1, and a main substrate 2 is arranged inside the insertion hole 1b. A connector 2a is provided on the upper surface of one end of the main board 2 facing the insertion hole 1b.
Is provided, and the connector 3g of the extension board 3 is connected to the connector 2a. At the other end of the extension board 3,
A connector 3c is provided, and a cable is connected to the connector 3c.

As shown in FIG. 3, the holder 4 of the extension board 3 mounted in the main body 1 of the apparatus is formed in a U shape, and rails 4a in the front-rear direction are projected in two steps on both inner sides of the holder 4 for guiding. In addition to forming the groove 4b, a locking portion 4c is provided at the center of the upper rail. Further, the rear portion is provided with a notch 4c for inserting a connector. As shown in FIG. 4, the holder 4 is attached to the attachment hole 1b of the main body 1 by fixing both U-shaped tip portions thereof.

Next, the assembly of the holding device for the expansion board having the above construction will be described. The board portion 3a of the extension board 3
Both sides of the extension board are inserted into the guide groove 4b of the holder 4, and the extension board is inserted into the holder 4. The connector 3g of the board portion is connected to the connector 2a on the main board 2, while the locking claw 3h of the stopper 3b is locked to the locking portion 4c of the holding body 4 to expand the expansion. The substrate 3 is fixed.

The extension board 3 is fixed to the holding body 4 by a locking claw 3
By locking and fixing by h, it is possible to prevent the extension board 3 from being accidentally pulled out from the main board even if the cable 9 connected to the extension board 3 is indexed. When removing the expansion board 3 from the main board 2, the lever 3d of the stopper 3b is bent inward so that the locking claw 3h is disengaged from the locking portion 4c of the holder 4. It can be removed from the substrate 2.

[0012]

As described above, in the extension board holding device according to the present invention, even when the cable is indexed to remove the cable connector connected to the board, the board is held by the holder and the holder fixing tool. It is possible to prevent it from being fixed and accidentally pulled out to the main board from the main board, and when trying to pull out the same board, the lever provided on the holder is bent so that the locking claw provided on the holder The extension board can be removed from the holder and the extension board can be removed, and the extension board holding device with improved reliability and usability can be provided.
