The first connector terminal 2 in contact with the 10 contact terminal portions 10a and the second connector terminal 3 in contact with the contact terminal portion 11a of the second card 11 are different from each other in the card insertion direction. Since the contact terminals 10a and 11a are arranged in correspondence with the positions where the contact terminal portions 10a and 11a are formed, it is possible to ensure contact between a plurality of types of cards having different shapes and the connector terminals of the connector device into which these cards are inserted. It is something that can be done.

  Further, the position of the second connector terminal 3 disposed in the housing portion 1a of the housing 1 is formed deeper in the card insertion portion than the position of the first connector terminal 2. The protruding positions of the rear edge of the first card 10 inserted into the housing 1 and the rear edge of the second card 11 inserted into the housing 1 are substantially the same. Since it is formed, even when a plurality of types of cards having different shapes are inserted into the same connector device, the projected position does not vary and the appearance is good.

Next, the operation when the first card 10 and the second card 11 are inserted into the connector device will be described with reference to FIGS.
First, in the initial state, that is, when the first card 10 is in the discharge position, the slide member 6 is urged in the card discharge direction by the urging force of the return spring 4, and the first card 10 The contact piece 2 b of the connector terminal 2 is restricted from projecting into the storage portion 1 a by the pressing plate portion 6 f of the slide member 6. In this case, the contact terminal portion 10a of the first card 10 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 receiving portion 6a with the holding recess 10e engaged by the engaging piece portion 7b of the first holding member 7. ing. (FIGS. 11 and 12)

  At this time, the tongue piece portion 7c provided facing the engaging piece portion 7b of the first holding member 7 is different from the pressing contact portion 9a provided protruding from the cover member 9. When the first card 10 is taken out from this state without being in contact, it can be easily taken out by the support piece portion 7a of the first holding member 7 being bent. Yes. (Fig. 19)

  Next, when the first card 10 is pressed in the card insertion direction, the notch portion 10b of the first card 10 and the corner portion on the other end side are the first card accommodation portion 6a of the slide member 6. By engaging with the first locking portions 6c and 6d, the slide member 6 can move in the insertion direction along with the insertion of the first card 10, and resists the biasing force of the return spring 4. Then, the slide member 6 moves in the card insertion direction, and one end of the lock pin 5 traces the heart-shaped cam groove 6h and is locked at the lock position. (FIGS. 13 and 14)

  In this case, the holding plate portion 6f of the slide member 6 is out of the restriction position of the contact piece 2b of the first connector terminal 2, and the contact portion of the contact piece 10a of the first card 10 and the contact piece 2b. 2c comes into contact. At this time, the tongue piece portion 7 c formed to face the engagement piece portion 7 b of the first holding member 7 is pressed by the pressing contact portion 9 a provided on the cover member 9. The engaging piece 7b is supported so as not to be detached from the holding recess 10e of the first card, and the first card 10 is securely held at the insertion position of the card. (Fig. 20)

  Next, when the second card 11 is in the initial state, that is, in the ejection position, the slide member 6 is urged in the card ejection direction by the urging force of the return spring 4, and the first card The contact piece 2b of the connector terminal 2 is restricted from projecting into the storage portion 1a by the pressing plate portion 6f of the slide member 6. Further, the contact terminal portion 11 a of the second card 11 is separated from the contact portion 3 c of the contact piece 3 b of the second connector terminal 3. At this time, the second card 11 is held in the second card accommodating portion 6b with the holding recess 11c engaged by the engaging piece portion 8b of the second holding member 8. ing. (FIGS. 15 and 16)

  Next, when the second card 11 is pressed in the card insertion direction, the front edge portion of the second card 11 becomes the second locking portion 6e of the second card housing portion 6b of the slide member 6. , The slide member 6 can move in the insertion direction as the second card 11 is inserted, and the slide member 6 resists the biasing force of the return spring 4 in the card insertion direction. The one end of the lock pin 5 traces the heart-shaped cam groove 6h and is locked at the lock position. (FIGS. 17 and 18)

  In this case, the pressing plate portion 6f of the slide member 6 is disengaged from the restriction position of the contact piece 2b of the first connector terminal 2, and the contact piece of the bottom surface of the second card 11 and the first connector terminal 2 is used. 2b is in sliding contact with the contact distance of the first connector terminal 2 in the process of inserting the second card 11 up to the insertion position of the card. 2b is regulated so as not to protrude into the storage portion 1a. Therefore, when a long card such as the second card 11 is inserted, the insertion resistance is increased or wear is caused. Can be prevented.

  At this time, the tongue piece portion 8c formed to face the engagement piece portion 8b of the second holding member 8 is pressed by the pressing contact portion 1j provided in the housing 1. The engaging piece 8b is supported so as not to be detached from the holding recess 11c of the second card 11, and the second card 11 is securely held at the card insertion position.

  In this way, the first and second holding members 7 and 8 have engaging pieces 7b and 8b that engage with the holding recesses 10e and 11c of the first and second cards 10 and 11, respectively. Supporting piece portions 7a and 8a for elastically supporting the engaging piece portions 7b and 8b are formed, and the housing 1 and the cover member 9 are separated from the supporting piece portions 7a and 8a at the card discharge position. At the card insertion position, the engaging piece portions 7b and 8b are engaged with the holding concave portions 10e and 11c of the first and second cards 10 and 11 by contacting the supporting piece portions 7a and 8a. Since the pressing contact portions 9a and 1j for joining are formed, the elastic force of the engaging portion can be increased when the card is inserted, and the elastic force of the engaging portion can be increased when the card is ejected. It is possible to weaken the force. Therefore, the card can be securely held when the card is inserted and the card can be easily taken out when the card is ejected.

  Further, the first card 10 is formed to be wide and thin, the second card 11 is formed to be narrower and thicker than the first card 10, and the first card 10 is The first locking portions 6c and 6d formed in the first card receiving portion 6a to be received are formed at opposed positions on the inner side of the slide member 6, and the first locking portions Since the width dimension between the portions 6c and 6d is smaller than the width dimension of the first card 10 and wider than the width dimension of the second card 11, the insertion of the second card 11 is performed. Sometimes, the second card 11 passes through the first locking portions 6c and 6d and comes into contact with the second locking portion 6e.

Note that the same components described in FIGS. 1 to 4 are denoted by the same reference numerals and description thereof is omitted.

  In this case, the first slide member 16 has a first card accommodating portion 16a in which the first card 10 is accommodated and a position opposite to the inner side of the first card accommodating portion 16a. A pair of first locking portions 16 c and 16 d that are in contact with both front end portions of the first card 10 are formed. The width dimension between the first locking portions 16 c and 16 d is formed to be narrower than the width of the first card 10 and wider than the width of the second card 11. .

  In addition, a pressing plate portion 16f suspended in a horizontal beam shape is formed at the front portion of the first card housing portion 16a. In the state where the first slide member 16 has moved to the card ejection position, the pressing plate portion 16f contacts the contact piece 2b of the first connector terminal 2 to contact the first connector terminal 2. The piece 2b is restricted from protruding into the storage portion 1a.

  Further, the one side surface portion of the first card housing portion 16a is made of a metal plate having a spring property or the like that engages with a holding recess portion 10e provided on the side surface portion of the first card 10 to be housed. The first holding member 17 is fixed. A first return spring 14 for urging the first slide member 16 in the card ejection direction is disposed on one end side, and is pivotally supported on the housing 1 on the other end side. A heart-shaped cam groove (not shown) with which a lock pin (not shown) is slidably contacted is formed.

  The second slide member 26 has a second card accommodating portion 26a that accommodates the second card 11, and a front end portion of the second card accommodating portion 26a. A second cross-shaped second locking portion 26b that contacts the edge portion is formed.

  Further, the one side surface portion of the second card housing portion 26a is made of a metal plate having a spring property and the like that engages with the holding recess portion 11c provided on the side surface portion of the second card 11 to be housed. The second holding member 18 is fixed. Further, a spring locking portion 26c that is received in the spring receiving portion 1i of the housing 1 and that is locked to one end side of the second return spring 24 is provided, and one end side of the second slide member 26 is provided. A heart-shaped cam groove (not shown) is formed in which a lock pin 25 pivotally supported on the housing 1 is slidably contacted.

Next, the operation when the first card 10 and the second card 11 are inserted into the connector device will be described with reference to FIGS.
First, in the initial state, that is, when the first card 10 is in the ejection position, the first return spring 14 is in a state where the first slide member 16 and the second slide member 26 overlap each other. And the urging force of the second return spring 24 is biased in the card ejection direction, and the contact piece 2b of the first connector terminal 2 is stored in the holding plate portion 16f of the first slide member 16. Protruding into the part 1a is restricted. In this case, the contact terminal portion 10a of the first card 10 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 accommodating 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 are the first card of the first slide member 16. The first slide member 16 and the second slide member 26 move in the insertion direction along with the insertion of the first card 10 by engaging with the first locking portions 16c and 16d of the housing portion 16a. Thus, both the first slide member 16 and the second slide member 26 move together in the card insertion direction against the biasing force of the first return spring 14 and the second return spring 24. Thus, the lock pin 25 or the like is locked at a lock position of a heart-shaped cam groove (not shown).

  In this case, the pressing plate portion 16f of the first slide member 16 is disengaged from the restriction 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 piece 2b. The contact portion 2c comes into contact. (FIGS. 25 and 26)

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

  Next, when the second card 11 is pressed in the card insertion direction, the front edge portion of the second card 11 becomes the second engagement of the second card accommodation portion 26 a of the second slide member 26. By engaging with the stop portion 26b, the second slide member 26 can move in the insertion direction along with the insertion of the second card 11, and resists the urging force of the second return spring 24. Only the second slide member 26 moves in the card insertion direction and is locked by the lock pin 25 at a lock position of a heart-shaped cam groove (not shown). (FIGS. 29 and 30)

  In this case, 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, so that the bottom surface of the second card 11 and the In the process in which the second card 11 is inserted to the insertion position of the card without sliding contact with the contact piece 2b of the first connector terminal 2, the contact piece 2b of the first connector terminal 2 is Since it is regulated so as not to protrude into the storage portion 1a, when a long card such as the second card 11 is inserted, the insertion resistance is increased and the occurrence of wear or the like is completely prevented. It can be prevented.
