A heart-shaped cam groove (not shown) with which a lock pin 25 axially supported by the housing 1 is slidably contacted is formed in the.

Next, referring to FIGS. 23 to 30, the first
The operation of inserting the card 10 and the second card 11 into the connector device will be described. First, in the initial state, that is, when the first card 10 is at the ejection position, the first slide member 16 and the second slide member 26 are overlapped with each other in the front-rear direction, and the first return spring 14 is provided.
Also, the contact piece 2b of the first connector terminal 2 is urged in the card ejection direction by the urging force of the second return spring 24 and the pressing plate portion 1 of the first slide member 16.
It is restricted from projecting into the storage portion 1a by 6f. In this case, the contact terminal portion 1 of the first card 10
0a is separated from the contact portion 2c of the contact piece 2b.
At this time, the first card 10 is held in the first card holding portion 16a by the first holding member 17. (Figs. 23 and 24)

Next, when the first card 10 is pressed in the card insertion direction, the cutout portion 10b of the first card 10 and the corner portion on the other end side of the first slide member 16 are aligned with each other. First locking portion 16 of the first card storage portion 16a
By engaging with c and 16d, the first slide member 16 and the second slide member 26 become movable in the insertion direction as the first card 10 is inserted, and the first return spring 14 Also, both the first slide member 16 and the second slide member 26 move together in the card insertion direction against the urging force of the second return spring 24, and are not shown by the lock pin 25 or the like. It is locked in the lock position of the heart-shaped cam groove.

In this case, the pressing plate portion 16f of the first slide member 16 is displaced from the regulating position of the contact piece 2b of the first connector terminal 2, and the contact terminal portion 10a of the first card 10 and the contact terminal portion 10a are removed. The contact portion 2c of the contact piece 2b contacts. (Figs. 25 and 26)

Next, when the second card 11 is in the initial state, that is, in the ejecting position, the first slide member 16 and the second slide member 26 have the first return spring 14 and the second slide member 26. The return piece 24 is urged in the card ejection direction by the urging force of the return spring 24, and the contact piece 2b of the first connector terminal 2 is held by the pressing plate portion 16f of the first slide member 16 in the storage portion 1a. It is restricted to project inside. The contact terminal portion 11a of the second card 11 has a contact piece 3b of the second connector terminal 3.
Is separated from the contact portion 3c. At this time, the second card 11 is inserted into the first card accommodating portion 16a of the first slide member 16 and is held in the second card accommodating portion 26a by the second holding member 18. It has become a thing. (Figure 27, Figure 28)

Next, when the second card 11 is pressed in the insertion direction of the card, the front edge of the second card 11 becomes the second card accommodating portion 26a of the second slide member 26. By engaging with the locking portion 26b of No. 2,
The second slide member 26 becomes movable in the insertion direction as the second card 11 is inserted, and resists the biasing force of the second return spring 24 to cause the second slide member 2 to move.
Only 6 moves in the card insertion direction and is locked by the lock pin 25 in the lock position of the heart-shaped cam groove (not shown). (Figure 29, Figure 30)

In this case, since the first slide member 16 does not move and the pressing plate portion 16f regulates the contact piece 2b of the first connector terminal 2, the second card 11 of the second card 11 is prevented. The bottom surface and the contact piece 2b of the first connector terminal 2 are not in sliding contact with each other, and the second card 11
However, in the process of being inserted up to the insertion position of the card, the contact piece 2b of the first connector terminal 2 is inserted into the storage portion 1a.
Since it is regulated so as not to project inward, when inserting a card having a long length such as the second card 11, it is possible to completely prevent the insertion resistance from increasing and the occurrence of wear or the like. It is possible.
