JP 2002-110291 A

  In recent years, there has been a demand for a combined connector that can mount a plurality of cards. In a plurality of cards inserted into such a card connector, the positions of the contact pads and the positions of the partition walls that partition the contact pads differ depending on the standards. In the conventional card connector as described above, when a card of a standard different from the detection target card (non-detection target card) is inserted, the pair of contact terminals are moved by the partition wall of the non-detection target card, There is a problem in that both cards come into contact with each other, and the card mounting can be erroneously detected.

  The present invention has been made in view of such a problem, and even when the card attachment is detected using the contact pad of the card, it is erroneously detected as the non-detection target card is inserted. An object of the present invention is to provide a card connector capable of preventing the situation.

  The card connector according to the present invention includes a housing capable of selectively mounting a plurality of cards having different partition wall shapes arranged between contact pads, and a pair of card detections that contact the same contact pads of a detection target card. A contact portion for contact with the partition wall of the non-detection target card and moving in the height direction of the partition wall on one of the contact terminals for card detection. The terminal is separated from the other contact terminal in the height direction of the partition wall.

  According to the card connector described above, since one contact terminal for card detection is separated from the other contact terminal in the height direction of the partition wall by the contact portion, one contact terminal for card detection is Since it can be prevented from moving to the other contact terminal side along the side wall of the partition wall and conducting both of them, even when detecting the mounting of the card using the contact pad of the detection target card Thus, it is possible to prevent a situation in which the card is erroneously detected as the non-detection target card is inserted.

  In the card connector, it is preferable that a part of the card detection contact terminal protrudes toward the partition wall of the non-detection target card to form the contact portion. In this way, a part of the contact terminal for card detection is projected to the partition wall side of the non-detection target card to form the contact portion, so that one contact terminal for card detection can be provided with an inexpensive and simple configuration. It becomes possible to prevent the both from conducting by moving to the other contact terminal side along the side surface of the partition wall.

  In the card connector, it is preferable that the contact portion is provided at a position separated from a contact portion with the contact pad in the contact terminal for detecting the card. In this case, since the contact portion that contacts the partition wall of the non-detection target card is provided at a position separated from the contact portion of the contact terminal for card detection with the contact pad, the contact portion of the contact terminal Can be prevented from coming into contact with the partition wall, and the contact portion can be prevented from being worn, so that it is possible to ensure contact stability in the contact terminals for detecting a pair of cards.

  In the card connector, the contact portion of the card detection contact terminal with the contact pad is formed by a top of a curved portion formed at one end of the contact terminal, and one contact having the contact portion. It is preferable that the curved shape portion of the terminal is configured to be accommodated in the curved shape portion of the other contact terminal. In this case, since the curved shape portion of one contact terminal having the abutting portion is configured to be accommodated in the curved shape portion of the other contact terminal, the contact terminal is temporarily attached as the non-detection target card is inserted. Even when one contact terminal having a contact portion moves to the other contact terminal side, it is possible to reliably prevent both contact terminals from contacting each other.

  In the card connector, the first contact terminal for the detection target card is provided on the front side of the housing in the card insertion direction, while the non-detection target card is provided on the back side in the card insertion direction with respect to the first contact terminal. The second contact terminal is preferably provided. In this case, the first contact terminal for the detection target card is disposed on the near side in the card insertion direction, while the second contact terminal for the non-detection target card is disposed on the back side in the card insertion direction. In the card connector in which the mounting position is shifted back and forth in the card insertion direction according to the type of card, it is possible to reliably prevent erroneous detection due to insertion of a non-detection target card inserted to the back side.

  In the card connector, the proximal end portion of the first contact terminal is disposed on the card insertion slot side, while the distal end portion is extended toward the back side in the card insertion direction, and the contact portion is the proximal end portion. It is preferable to provide a part on the side. In this case, since the contact portion is provided on a part of the base end portion side of the first contact terminal arranged on the card insertion port side, the leading end portion contacts with the insertion of the detection target card. Therefore, it is possible to prevent the first contact terminal from buckling.

  According to the present invention, since one contact terminal for card detection is separated from the other contact terminal in the height direction of the partition wall by the contact portion, the one contact terminal for card detection is separated from the partition wall. It is possible to prevent both from conducting by moving to the other contact terminal side along the side surface of the card, so even when detecting the mounting of the card using the contact pad of the detection target card, It is possible to prevent a situation in which a detection target card is erroneously detected as the card is inserted.

Then, when the card A is pushed after being pushed to the farthest side, the front end of the locking member 503 is locked to the locking portion 515 of the recessed groove 516. FIG. 9 shows a state where the locking member 503 is locked to the locking portion 515 and the card A is locked. When the card A is locked, the curved portion 213 of the card A contact 212 enters the concave portion 705 of the card A, and the top portion 213a is in contact with the contact pad 706.

  In this case, the curved portions 214a and 215a of the detection contacts 214 and 215 are in contact with the same contact pad 706 as shown in FIG. Further, as shown in FIG. 11, the curved shapes 214 a and 215 a are in contact with the contact pad 706 in a state where they are arranged at substantially the same position in the thickness direction of the card A. At this time, the overhanging portion 214b of the detection contact 214 does not contact the partition wall 707 of the card A, and the top of the curved shape portion 214a contacts the contact pad 706 similarly to the top of the curved shape portion 215a. It is configured as follows. As described above, in the connector 1 according to the present embodiment, the pair of detection contacts 214 and 215 come into contact with the same contact pad 706, and the conduction state between the two is switched, thereby detecting the mounting of the card A. It is possible.

  12 to 14 are top views showing the operation when the card B is inserted into the connector 1 according to the present embodiment. 15 and 16 are a bottom view and a side sectional view of the periphery of the detection contacts 214 and 215 of the connector 1 in the state shown in FIG. FIGS. 17 and 18 are bottom views of the periphery of the detection contacts 214 and 215 of the connector 1 in the state shown in FIGS. 13 and 14, respectively. In FIGS. 12 to 14 and 15 to 18, the cover member 3 is omitted for convenience of explanation.

  FIG. 12 shows a state immediately before the card B is inserted into the card mounting space and the right end portion of the card B comes into contact with the second contact portion 505 of the slide member 501. The card B is inserted into the card mounting space in a state where the side surface and the lower surface are aligned with the second guide portion 205 of the housing 2. In the state illustrated in FIG. 12, the card B is not in contact with the slide member 501, and the slide member 501 is in a state of being disposed at the initial position (that is, the frontmost position). The locking member 503 has a front end located at the rear end of the linear guide groove 517.

  In this case, the curved portions 214a and 215a of the detection contacts 214 and 215 are arranged at positions where they are accommodated in the same concave portion 802 of the card B as shown in FIG. The protruding portion 214b of the detection contact 214 is disposed at a position corresponding to the partition wall 804 adjacent to the recess 802 (the right-side partition wall 804 shown in FIG. 15). Therefore, when the curved portions 214a and 215a are accommodated in the recesses 802 as the card B is inserted, the overhanging portion 214b is pushed down by the lower surface of the partition wall 804 as shown in FIG. The contact 214 is separated from the detection contact 215 in the height direction of the partition wall 803. For this reason, the curved portion 214 a of the detection contact 214 does not contact the curved portion 215 a of the detection contact 215.

  In particular, the curved portion 215a of the detection contact 215 has a gentle curved shape so that it can be accommodated when the curved shape portion 214a of the detection contact 214 approaches (see FIG. 16). Therefore, even if the curved shape portion 214a of the detection contact 214 is moved to the curved shape portion 215a side of the detection contact 215 along with the insertion of the card B, the detection contacts 214 and 215 are in contact with each other. It is possible to prevent the situation.

  When the card B is pushed in from the state shown in FIG. 12, the right end of the card B comes into contact with the second contact part 505 of the slide member 501 as shown in FIG. B can be slid integrally with B. When the right end of the card B comes into contact with the second contact portion 505, the locking member 503 has its front end positioned at the rear end of the linear guide groove 517. Is maintained.

  In this case, the curved portions 214a and 215a of the detection contacts 214 and 215 shift from the state shown in FIG. 15 to the state shown in FIG. Also in the state shown in FIG. 17, the overhanging portion 214 b of the detection contact 214 is pressed down by the lower surface of the partition wall 804, and the detection contact 214 extends from the detection contact 215 to the height of the partition wall 804. They are separated in the vertical direction. For this reason, the curved shape portion 214a of the detection contact 214 becomes the curved shape portion 215a of the detection contact 215 even at the timing when the right end of the card B contacts the second contact portion 505 of the slide member 501. There is no contact.

  When the card B is further pushed in from the state shown in FIG. 13, the slide member 501 moves against the urging force of the compression spring 502 as the card B moves rearward. Accordingly, the locking member 503 slides in the linear guide groove 517 and the first guide groove 513. Then, after pushing the card B to the rearmost side, when the hand for pushing the card B is released, the front end of the locking member 503 is locked to the locking portion 515 of the recessed groove 516. FIG. 14 shows a state in which the locking member 503 is locked to the locking portion 515 and the card B is locked.

  In a state where the card B is locked, the curved portion 211 of the card B contact 210 enters the concave portion 802 of the card B, and the top portion 211a is in contact with the contact pad 803. The curved portions 214a and 215a of the detection contacts 214 and 215 shift from the state shown in FIG. 17 to the state shown in FIG. That is, the curved portions 214 a and 215 a of the detection contacts 214 and 215 pass through the concave portion 802 of the card B and are in contact with the lower surface of the card B. For this reason, the curved shape portion 214a of the detection contact 214 does not contact the curved shape portion 215a of the detection contact 215 through the card B insertion process.

  As described above, in the connector 1 according to the present embodiment, the detection contact 214 is provided with the overhanging portion 214b as a contact portion that contacts the partition wall 804 of the card B and moves in the height direction of the partition wall 804. The detection contact 214 is separated from the detection contact 215 in the height direction of the partition wall 804. Accordingly, it is possible to prevent the detection contact 214 from moving to the detection contact 215 side along the side surface of the partition wall 804 and conducting both of them, so that the contact pad 706 of the card A that is the detection target card can be removed. Even in the case where the insertion of the card A is detected by using it, it is possible to prevent a situation in which it is erroneously detected with the insertion of the card B that is a non-detection target card.

  In particular, in the connector 1 according to the present embodiment, a part of the detection contact 214 is projected to the partition wall 84 side of the card B to form the projecting part 214b as a contact part. The conduction between the detection contact 214 and the detection contact 215 can be prevented with an inexpensive and simple configuration.

  Moreover, in the detection contact 214, the overhanging portion 214b is disposed at a position separated from the curved shape portion 214a. Therefore, the curved shape portion 214a of the detection contact 214 can be prevented from coming into contact with the partition wall 804 of the card B, and the curved shape portion 214a can be prevented from being worn. The contact stability at 215 can be ensured.

  Further, in the connector 1 according to the present embodiment, the card A contact 212 is disposed on the front side in the card insertion direction, while the card B contact 210 is disposed on the back side in the card insertion direction. In the connector 1 in which the mounting position is shifted back and forth in the card insertion direction according to the type of card, it is possible to reliably prevent erroneous detection associated with the insertion of the card B inserted to the back side.

  In particular, in the connector 1 according to the present embodiment, the base end portion of the card A contact 212 is disposed on the card insertion port 4 side, while the distal end portion is extended toward the back side in the card insertion direction, The protruding portion 214b is provided in a part on the base end side. Thereby, since the situation where the front-end | tip part contact | abuts with insertion of the card | curd A can be prevented, the situation where the card | curd A contact 212 buckles can be prevented.

  In addition, this invention is not limited to the said embodiment, It can change and implement variously. In the above-described embodiment, the size, shape, and the like illustrated in the accompanying drawings are not limited to this, and can be appropriately changed within a range in which the effect of the present invention is exhibited. In addition, various modifications can be made without departing from the scope of the object of the present invention.

  For example, in the above-described embodiment, the protruding portion 214b that contacts the lower surface of a partition wall 804 (to be described later) and moves the detection contact 214 in the height direction of the partition wall 804 as the card B is inserted is a contact portion. However, the configuration of the contact portion is not limited to this, and can be changed as appropriate. Any configuration may be employed as long as the detection contact 214 can be moved in the height direction of the partition wall 804 by abutting against a lower surface of a partition wall 804 described later with the insertion of the card B.
