A problem in the prior art is that the connector for connecting the PC card and the cable is easily damaged. The reason for this is that the connection between the PC card and the cable is weak because the PC card itself is thin and small. That is, since a force is applied to the connection connector 15 through the connection plug 8 due to the twist of the cable connected to the PC card, solder or PC at the connection portion between the pin of the connection connector 15 and the PC card
Force is applied to the conductive pattern on the printed circuit board of the card. As this is repeated many times, these internal signal lines are disconnected and the PC card becomes unusable.

One of the causes of the twisting of the cable is that a noise filter 10 for removing noise is present near the connection plug 8 for connecting the PC card 14 and the cable 9 in FIG. Generally, the noise filter 10 is larger than the thickness of the PC card 14 and is located at almost the same position with respect to any PC card. Therefore, as shown in FIG. 5, two PC cards are simultaneously inserted into the PC card slot. When inserted in 12, the noise filters 10 interfere with each other, and the cable 9 is twisted and a force is applied to the connection plug 8.

An object of the present invention is to provide a PC card in which a connection portion between the PC card and a cable is hardly damaged.

[0011]

Next, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention, which is a PC.
It is a perspective view when the upper lid of a card is removed. In FIG. 1, a connection plug 8 is attached to the tip of a cable 9 which is a signal line from a peripheral device (not shown), and a noise filter 10 for removing noise is attached to the cable 9 close to the connection plug 8. A connection connector 1 is attached to the PC card 4 for connection with the cable 9, and the connection plug 8 is inserted into the connection connector 1 to enable connection between the PC card 4 and the cable 9.

In particular, the connector 1 can be freely moved in the horizontal direction along the guide rail 2 attached to the PC card 4, and the connector 1 and the circuit board 5 inside the PC card are separated from each other. It is connected by a plurality of cords 6. A shield plate 3 is provided between the connector 1 and the circuit board 5 to prevent dust and the like from entering the inside of the PC card 4, and even if the connector through which the slit for passing the cord 6 moves, the cord 6 is It is opened so that it does not come into contact with the slit.

Next, the operation of the first embodiment of the present invention will be described with reference to FIG. Figure 2 is a personal computer PC
In the perspective view in which two PC cards 4 are inserted into the card slot, the personal computer main body, the PC card slot and the guide rail 2 are not drawn for easy viewing. Since the connector 1 can be arbitrarily displaced in the horizontal direction, it can be displaced in different positions from each other as shown in FIG. Even if one of the two PC cards is a conventional PC card and the connection connector is fixed, if the other is a PC card using the connector of the PC card of the present invention, the position of the connection connector 1 The noise filters 10 can be separated from each other, and the two noise filters 10 do not collide with each other so that the cable 9 does not twist. Since the cord 6 is thin in this embodiment, P
There is a feature that the thickness of the C card 4 can be reduced.

Next, a second embodiment of the present invention will be described with reference to FIG. FIG. 3 is a perspective view of the second embodiment of the present invention when the upper lid of the PC card is removed. In FIG. 1, a connection plug 8 is attached to the tip of a cable 9 which is a signal line from a peripheral device (not shown), and a noise filter 10 for removing noise is attached to the cable 9 close to the connection plug 8. In addition, the PC card 4 has a connector 1 for connecting to the cable 9.

[0018]

The first effect is that the connection between the PC card and the cable is hardly damaged. The reason is that the connector can be moved freely in the horizontal direction, so if the PC card and the cable are not kinked because the noise filters do not collide with each other if the PC card and the other PC card are displaced from each other. This is because unreasonable force is not applied to the part.

The second effect is that noise is less likely to be added to the signal of the cable as compared with the conventional case. The reason is that by shifting the connection connectors of the two PC cards, the distance between the two cables is inevitably increased, so that the signal of one cable is less likely to get on the signal of the other cable as noise. is there.
