われる。When the contacts are joined to the contacts of the FPC, FFC, card, etc., the contact tail having spring property is brought into contact with the FPC, FFC, etc. to make electrical connection. Since no soldering or the like is performed, the connection between the connector and the FPC or FFC can be easily released. Therefore, while the operation of connecting or disconnecting the FPC, FFC, or the like to the connector is facilitated, there is a case where the contact portion becomes unsatisfactory due to dirt on the joint portion, or the joint portion is bent or damaged to make the connection impossible. The mechanical and electrical functions of the connector are quickly impaired, especially when the card is frequently inserted and removed.

部をプリロード構造とする。SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks and to provide a connector having stable mechanical and electrical functions despite repeated insertion and removal of a card. For this reason, the contacts used in the connector of the present invention can be used for either front fitting or back fitting of the FPC at one end by punching out one elastic metal plate and then bending it. In addition to the swelling parts that sandwich the FPC from the upper and lower sides with respect to the slit provided in the center, a folding spring structure that does not buckle when the card is fitted is provided in the middle part. In order to clean the edge of the board without contacting the resin surface of the card, a semi-cylindrical ridge is provided in the middle of the lever spring structure, and the other end of the connector has a preload structure.

The contact 2 is obtained by stamping and molding one elastic metal plate into an elongated strip shape.
A slit 3 is formed at one end, and bulges 4 and 4 are provided on both sides of the slit 3 so as to sandwich the FPC. To do. A thin plate member 7 extending from the intermediate portion 6 toward the other end is bent upward so that the contact 2 does not buckle when the card is fitted to form a folded spring 8.

ジ部でのクリーニングに耐える強度を持たせる。In order to reduce the coefficient of friction of the surface of the return spring 8 that comes into contact with the card 9 to be inserted, the surface 10 of the spring 8 is finished by adding chamfers, and the contact pressure is 30 to 70 gr / cm. 2 to prevent damage on the card side, while the other contact side
A semi-cylindrical convex portion 11 is provided in the middle of the spring 8 so as to have strength enough to withstand cleaning at the edge of the substrate.

なっている。Further, the wing structure of the contact 2 is mounted in the connector 1 in a preloaded state as shown in FIG. 2, and the tip portion 12 of the spring 8 stabilizes the contact height and the card to be inserted. The surface of the spring 8 is cleaned by the substrate edge portion 13 without making contact with the resin surface of 9.

りする必要がなくなる。Since the present invention is configured as described above, the connector 1 ensures that the contact 2 is electrically connected to the contact on the FPC side, and the card side of the card is not damaged.
Make sure electrical connection with the card. Further, since the contact 2 has a folded spring structure and is formed with a semi-cylindrical convex portion, it is possible to maintain sufficient strength without buckling even when repeatedly coming in and out of contact with the card. Furthermore, when inserting the FPC or FPC into the connector,
Since the insertion can be done without worrying about the contact surface of the C or FFC, there is no need to invert or twist the FPC or FFC.
