The left end of the insulator 4 is rotatably connected to the left end of the holder 5 via a shaft 7, and the right end of the insulator 4 is a means for locking the right end of the holder 5, for example, swingable. Naive hook 8
Is provided.

In such a connector 2, when the card 1 is inserted from the card insertion opening (card insertion guide) 9 of the holder 5 and the holder 5 is rotated in the direction of arrow A to lock the right end of the holder 5 to the hook 8, 6 contacts the contact 3 and is electrically connected to maintain its state. However,
Upon the electrical contact, the terminal 6 and the contact 3 are accompanied by very slight sliding, and the wear of the terminal 6 and the contact 3 can be ignored.

Next, when the hook 8 is operated to release the lock of the holder 5, the holder 5 returns to its original state by the restoring force of a compression coil spring or the like (not shown), and the card 1 can be removed.

[Problems to be solved by the invention]

In the zero insertion force connector in which the contact 17 and the contact 17 are connected, the first connection is made when the holder 11 holds the electrical connection body 31.
Of the switch 15 and the first switch 15 causes the holder 11 or the insulator 12 to move.
An electromagnetic magnet 16 for rotating the electric terminal 32 and the contact 17 to connect with each other, and a normally-closed type second switch 21 for connecting the first switch 15 in series and opening the first switch 15 by an external operation. It is a zero insertion force connector characterized by comprising.

[Action]

According to the above means, when the electric connector is inserted into the holder, the electromagnetic McNet operates by the operation of the first switch, and the terminal of the electric connector and the contact are connected without sliding. Then, the operation of the electromagnetic switch is stopped by the operation of the second switch, and the connection is released. Therefore, the insertion / removal operation of the electrical connector is simplified as compared with the conventional case.
