Description

  The present invention is a push-in / push-eject type card connector that prevents the card from coming out due to impact or the like when the memory card is fitted into the connector body, and prevents the card from popping out when the card is ejected. The present invention relates to a locking device in a card connector.

  A conventional push-in / push-eject type card connector is shown in FIGS. 7A and 7B (Patent Document 1). In these figures, a metal body is put on a flat housing 10 to constitute a connector body, and one end opening portion of the connector body is a card insertion slot 14. A slider 12 is disposed in the housing 10 so as to be movable forward and backward by a first spring 17 and a second spring 18 at both ends. A horizontal hole 24 is formed in the middle of the slider 12, and a lock spring 19 is provided so as to face the horizontal hole 24. Further, an ejecting portion 25 as shown in FIG. 8 is formed on the side surface of the slider 12.

In such a configuration, when the memory card 11 is inserted into the card insertion slot 14, the inclined tip portion 15 of the memory card 11 contacts the protruding portion 21 of the lock spring 19. When the memory card 11 is further pushed in, the lock spring 19 is pushed out like a chain line by the side surface of the memory card 11, and the free end 22 protrudes toward the opening 23 formed in the side wall 13 of the housing 10. When the memory card 11 is further pushed in and the concave portion 16 of the memory card 11 reaches the position of the protruding portion 21 of the lock spring 19, the lock spring 19 is restored and the protruding portion 21 is fitted into the concave portion 16. At the same time, the leading end 15 of the memory card 11 contacts the contact surface 20 of the slider 12.
When the memory card 11 is further pushed in this state, the memory card 11 and the slider 12 move integrally against the first spring 17 and the second spring 18. At this time, when the bending end of the locking pin 26 is guided through the forward groove 27 and the pushing out of the memory card 11 is stopped when the memory card 11 stops, the bending end of the locking pin 26 is engaged. The slider 12 is locked by being locked in the stop groove 28 (the state shown in FIG. 7B). The above is the push-in operation.

When the memory card 11 is removed, if the memory card 11 is pushed in the state shown in FIG. 7B, the bent end of the locking pin 26 changes its path from the locking groove 28 toward the return groove 29, and the first spring 17. The second spring 18 pushes the slider 12 back to its original position. At this time, the memory card 11 is in the chain line state of FIG. When the memory card 11 is further pulled out by hand, the lock spring 19 is pushed out in a chain line state and is removed from the recess 16, and the memory card 11 is removed from the card insertion slot 14. The above is the push-eject operation.
