DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an expansion card insertion / extraction mechanism of the present invention will be described below with reference to the drawings. The same members or those having the same functions as those in FIG. 6 are denoted by the same reference numerals. In FIG. 1, reference numeral 1 denotes a computer device, which is provided with an expansion card insertion / extraction mechanism 2 at an upper portion. The expansion card insertion / extraction mechanism 2 is a so-called hot-line insertion / extraction mechanism that enables an expansion card to be inserted / extracted without turning off the power of the computer device 1. 3 for opening and closing the door. As shown in FIG. 2, an expansion card 5 inserted into the card insertion slot 3 (three cards are shown in the illustrated example, but the number is arbitrary). Is to be implemented via
The expansion card mounting board 6 is covered with a board shielding cover 8. An expansion card fitting 9 is provided on one end surface of the expansion card 5 in the vertical direction.

In FIG. 2, a cover member 10, which is a main component of the present invention, has opposite side surface portions 10 which face each other via a groove 11.
B, 10b have a thin plate shape in which the upper edges are connected at an end face 10a, a bent part 12 is formed at the right end of the end face 10a, and a locking claw 13 is provided at the left end of the side plate parts 10a, 10b. (See FIGS. 4 and 5). The cover member 10 is attached to the card slot 3 so as to cover each expansion card 5 as follows. That is, as shown in FIG. 3, the locking claws 13 and 13 are inserted and locked into the locking holes 15 and 15 of the frame 14 of the computer device 1, and as shown in FIGS. Is superimposed on the bent portion 9a of the expansion card fitting 9, and the fixing lever 16 is fixed from above.

The fixed lever 16 includes a rigid plate member 17, an elastic plate 18 connected to the plate member 17, a fan-shaped elastic locking member 19 integral with the plate member 17, and a switch operating piece 20. And is rotatably supported on the shaft 21. The shaft 21 is fixed to a desired portion of a protective cover 24 described later. Reference numeral 22 denotes a detection switch that detects the movement of the fixed lever member 16 and is attached to the detection board 23. A board protection cover 24 is provided above the detection board 23.

In FIG. 4, the elastic plate 18 of the fixed lever 16 is pressed against the bent portion 12 and the elastic locking member 19 is locked to the board protection cover 24, so that the cover member 10 is connected to the expansion card 5. Pressed together and fixed. In this state, the switch operation piece 20 comes into contact with the actuator 22a of the detection switch 22 attached to the detection board 23, whereby the power of the expansion card 5 is turned on. When inserting and removing the expansion card 5, the elastic locking member 19 of the fixed lever 16 is pressed to release the locking with the board protective cover 22, and the counterclockwise rotation is performed, thereby turning the cover member as shown in FIG. At the same time, the switch operation piece 20 is separated from the actuator 24a, and the power of the expansion card 5 is turned off.

The material of the cover member 10 is a non-conductive material which has no danger of short-circuiting even when it comes into contact with the expansion card mounting board 6, has good workability, and conforms to various safety standards. For example, a resin material such as a vinyl chloride plate, an ABS resin, or a polycarbonate is suitable. Also,
As the material of the fixing lever 16, a material having good workability and having elasticity for pressing the cover member 10 and the expansion card fitting 9, for example, polyamide is preferable. Further, the material of the substrate shielding cover 8 may be the same as that of the cover member 10.

In the above embodiment, the expansion card 5
Has been described above, but the number of cards is not limited, and the shape of the expansion card may be a shape other than the above embodiment. As described above, when the fixed lever member 16 is released when the expansion card 5 is inserted or removed, the detection switch 22 is automatically operated to turn off the power of the expansion card 4. Electric shock due to 4 is eliminated. Further, the cover member 10 and the expansion card metal fitting 9 of the expansion card 5 are fixed together by one fixed lever member 16, and the detection switch 22 is operated by the fixed lever member 16. Only the detection switch 22 is required to operate the power supply, and the number of components can be reduced.

[0013]

As described in detail above, according to the present invention, when the power of the expansion card is turned on, the expansion card is covered with the cover member, and when the expansion card is removed, the cover member is fixed. When the card is released, the power is necessarily turned off, so that an electric shock at the time of card insertion and removal can be prevented, work safety can be ensured, and a short circuit due to contact with a conductive material can be reliably prevented. Further, the switch for operating the power supply of the expansion card is only a detection switch, and the number of parts can be reduced.
