When the first card is inserted into the slot in a predetermined direction, the first locking portion is locked in the locking recess of the first card, and the first card is predetermined. If inserted in a direction other than The first locking portion is pressed by the first card, and the locking arm is elastically deformed in a direction away from the first card, whereby the second locking portion becomes an inner wall surface of the slot of the housing. It is latched by the recessed part or convex part.

  In the case of such a card connector, when the first card is inserted into the slot in a predetermined direction, the first locking portion is locked in the locking recess of the first card, and the slider is in the first position. It is possible to slide along with the card. On the other hand, when the first card is inserted in a direction other than a predetermined direction, the second locking portion is locked to the concave or convex portion of the inner wall surface of the slot of the housing, thereby preventing the slider from sliding. Is done. For this reason, it is possible to prevent the first card from being erroneously inserted in a direction other than the predetermined direction. In addition, since the second locking portion is locked to the concave portion or the convex portion of the inner wall surface of the slot of the housing, the state where the slider is positioned at the card discharge position is maintained. An erroneous insertion of the first card can be easily recognized.

  In the case where the card connector is further provided with a position restricting means provided in the slot of the housing and capable of restricting movement of the first card in a predetermined direction, the second locking portion is a recess of the housing.

The connection piece 621 is electrically connected to the substrate (not shown). The intermediate portion and the distal end portion are disposed in a lower space of the first contact 300 in a state where the base end portion is locked in the second locking groove 182a.

  The distal end portion of the first switch piece 610 is pressed by the guide block 800 a that moves in the card insertion direction together with the slider 200, and comes into contact with the distal end portion of the second switch piece 620. As a result, a signal indicating that the small and large cards 10 and 20 have been inserted into the electronic device on which the card connector C is mounted is output through a substrate (not shown). When the slider 200 is positioned at the card insertion position, the leading end portions of the first and second switch pieces 610 and 620 are further pressed by the guide block 800a and are accommodated in the above-described cutout portion of the rear wall portion 104a of the body 100a.

 The card connector C having such a configuration is assembled by the following procedure. First, as shown in FIG. 10, the contact portion 430 of the second contact 400 is inserted from the front of the bottom plate portion 101a while being aligned with the contact mounting groove 110a of the body 100a. Then, the press-fit portions 420 of the second contacts 400 are press-fitted into the long groove portions 111a of the contact mounting grooves 110a, respectively. Accordingly, the second contacts 400 are attached to the bottom plate portion 101a of the body 100a. In this state, as shown in FIG. 3, the contact portions 430 are respectively arranged in the intermediate area in the card insertion direction in the lower space of the slot 105a through the through hole portion 113a of the contact mounting groove 110a. At the same time, the connection portion 410 of the second contact 400 protrudes from the front of the contact mounting groove 110a.

  Thereafter, the press-fitting plates 720a and 720b of the position regulating springs 700a and 700b are inserted into the mounting holes 140a and 150a from the front opening portions 143a and 153a of the mounting holes 140a and 150a of the body 100a, respectively. Then, the projecting piece 750a of the position regulating spring 700a is inserted into the mounting hole 140a from the front opening portion 143a of the body 100a.

  Thereafter, the press-fitting plates 720a and 720b are press-fitted into the press-fitting holes 141a and 151a of the mounting holes 140a and 150a, respectively. Then, the fixing plates 710a and 710b of the position regulating springs 700a and 700b are sandwiched between the wall surface on one end side of the mounting holes 140a and 150a and the outer surface of the lower edge of the inner opening portions 142a and 152a. At the same time, the contact portions 740a and 740b of the position restricting springs 700a and 700b protrude inward from the inner opening portions 142a and 152a of the mounting holes 140a and 150a and face the slot 105a. At this time, the projecting piece 750a of the position regulating spring 700a enters the notch 144a of the body 100a, and the other end of the projecting piece 750a projects inward from the notch 144a of the body 100a and faces into the slot 105a.

  Thereafter, the locking piece 233a of the block mounting portion 230a of the slider 200 is inserted into the lateral hole 870a of the guide block 800a. At the same time, the guide convex portion 850a of the guide block 800a is fitted into the notch 232a of the block mounting portion 230a. Then, the flange 860a of the guide block 800a is placed on the support plate 231a of the block mounting portion 230a. Thereby, the guide block 800a is attached to the block attachment part 230a.

  Meanwhile, the locking piece 233b of the block mounting portion 230b of the slider 200 is inserted into the lateral hole 870b of the guide block 800b. At the same time, the guide convex portion 860b of the guide block 800b is fitted into the notch 232b of the block mounting portion 230b. Thereby, the guide block 800b is attached to the block attaching part 230b.

  Thereafter, the slider main body 210 of the slider 200 is inserted into the slot 105a from above, and the slider main body 210 is fitted between the inner side surfaces of the lower edges of the inner opening portions 142a and 152a of the mounting holes 140a and 150a. Then, the guide protrusions 850a and 860b of the guide blocks 800a and 800b are fitted into the pair of guide rails 190a of the body 100a, respectively. At the same time, the protruding portion 220 of the slider 200 is inserted into the housing recess 130a of the body 100a from above.

  Thereafter, one end of the hook pin 520 is fitted into the through hole 221 b of the protrusion 220 of the slider 200, and the other end of the hook pin 520 is inserted into the heart cam groove 530. Then, the holding plate 222a of the protrusion 220 and the protrusion 132a of the housing recess 130a are inserted into the front end and the rear end of the coil spring 510, respectively. As a result, the coil spring 510 is held in a compressed state between the pressing plate 222 of the protrusion 220 and the inner side surface of the housing recess 130a.

  When the slider 200 is released from the operator's hand, the pressing plate 222 is pressed by the coil spring 510, and the slider 200 moves in the slot 105a in the card ejection direction. And the front-end | tip part of the base board 221 of the slider 200 contact | abuts to the wall surface of the near side of the accommodation recessed part 130a. As a result, the slider 200 is positioned at the card ejection position.

At this time, the edge on the near side of the pair of window portions 211a of the slider 200 gets over the contact portions 740a and 740b of the position regulating springs 700a and 700b. Thereby, the contact portions 740a are respectively engaged with the window portions 211a, and the card biasing springs 214 are disposed in the near side area in the card insertion direction in the lower space of the slot 105a. At the same time, the contact portion 430 of the second contact 400 located on the most end side is inserted into the recess 840a of the guide block 800a, and the second contact 400 located on the other end side in the lower recess 850b of the guide block 800b. The contact portion 430 is inserted.

  Thereafter, the base end portions of the first and second switch pieces 610 and 620 of the position detection switch 600 are inserted into the first, second, and second locking grooves 181a and 182a of the body 100a, respectively. Thereby, the base end portion is locked in the first and second locking grooves 181a and 182a, respectively. At this time, the connection pieces 611 and 621 of the first and second switch pieces 610 and 620 are inserted into the slits of the first and second locking grooves 181a and 182a, respectively. Then, the connection pieces 611 and 621 protrude outward from the side wall portion 102a and the rear wall portion 104a of the body 100a. At the same time, the tip ends of the first and second switch pieces 610 and 620 are respectively arranged in the back area in the card insertion direction in the lower space of the slot 105a.

  Thereafter, the contact portion 330 of the first contact 300 is inserted from the rear of the rear wall portion 104a while being aligned with the narrow hole portion 122a of the contact mounting hole 120a of the body 100a. Then, the press-fit portions 320 of the first contact 300 are press-fitted into the wide hole portions 121a of the contact mounting holes 120a, respectively. Accordingly, the first contacts 300 are attached to the rear wall portion 104a of the body 100a. In this state, as shown in FIG. 3, the contact portion 330 is disposed above the first and second switch pieces 610 and 620 in the upper space of the slot 105a. At the same time, the connection portion 310 of the first contact 300 protrudes from the rear of the contact mounting hole 120a.

  Thereafter, the pair of reinforcing pieces 140b of the cover 100b are inserted while being aligned with the pair of insertion holes 170a of the body 100a. At the same time, the four locking projections of the side walls 102a and 103a of the body 100a are fitted into the four locking holes 161b of the pair of side plates 102b, respectively, and the rear of the body 100a is inserted into the locking holes 180b of the locking plate 105b. The locking convex part of the wall part 104a is fitted.

  At this time, the restriction plates 131b and 132b of the cover 100b come into contact with the side walls 103a and 102a of the body 100a, respectively. At the same time, the pair of front plates 103b of the cover 100b covers the front side opening portions 143a and 153a of the mounting holes 140a and 150a of the body 100a. Thereby, the edge part 170b of a pair of notch part of the front board 103b is arrange | positioned at the both sides of the 2nd opening 107a of the body 100a. In this way, the cover 100b is attached to the body 100a.

  The card connector C assembled in this way is used as follows in a state where it is mounted on a substrate (not shown).

  First, the small card 10 is inserted into the slot 105a through the first and second openings 106a and 107a of the body 100a with the electrode surface facing upward (that is, the small card 10 is in a predetermined normal orientation). Then, both end surfaces of the small card 10 in the width direction are respectively guided by the pair of upper guide portions 213 of the slider 200 and the contact portions 740a and 740b of the position regulating springs 700a and 700b.

  At this time, the lower surface of the small card 10 (that is, the surface opposite to the electrode surface) is urged upward by the card urging spring 214 of the slider 200. Thereby, the small card 10 moves upward.

  Thereafter, when the small card 10 is further inserted into the back side of the slot 105a, the electrode surface of the small card 10 sequentially comes into contact with the pair of both side position restricting pieces 120b and the center position restricting piece 110b of the cover 100b. That is, the lower surface of the small card 10 is urged by the card urging spring 214, and the electrode surface of the small card 10 is brought into contact with the pair of both side position restricting pieces 120b and the central position restricting piece 110b, thereby reducing the size of the small card 10. The insertion posture of the card 10 is kept substantially horizontal and is arranged at a height position corresponding to the connection space. Further, when the pair of both side position restricting pieces 120b and the center position restricting piece 110b are in contact with the electrode surface of the small card 10, one side portion in the width direction of the rear end surface of the small card 10 is pushed. Thus, the small card 10 is prevented from rotating in the circumferential direction, and the small card 10 is also prevented from swinging in the width direction around the tip of the card biasing spring 214. Thereby, the play at the time of insertion of the small card | curd 10 is prevented.

  In this insertion process, the overhanging portion 12 of the small card 10 presses the first locking portion 213a1 of the upper locking arm 213a of the slider 200 outward. As a result, the upper locking arm 213a is elastically deformed outward, and the tip of the upper locking arm 213a is displaced outward.

  Thereafter, when the small card 10 is further inserted into the back side of the slot 105a, as shown in FIG. 5, both corners of the tip of the small card 10 are respectively brought into contact with the upper guide surfaces 820a and 820b of the guide blocks 800a and 800b. Touch. Thereby, the direction of the small card 10 is directed straight along the card insertion direction at the center position in the slot 105a.

  During this insertion process, the first locking portion 213a1 of the upper locking arm 213a of the slider 200 is fitted into the locking recess 12a of the small card 10. Thereby, the front-end | tip part of the upper side latching arm 213a returns to an original position, and the 1st latching | locking part 213a1 latches the small card | curd 10. FIG.

  Thereafter, when the small card 10 is further inserted into the back side of the slot 105a, the upper guide surfaces 820a and 820b of the guide blocks 800a and 800b are pressed by both corners of the small card 10, respectively. As a result, the slider 200 moves from the card ejection position to the card insertion position together with the small card 10. At the same time, the guide protrusions 850a and 860b of the guide blocks 800a and 800b move along the pair of guide rails 130a of the body 100a.

  At this time, one end of the hook pin 520 rotates in the through hole 221 b of the slider 200, and the other end of the hook pin 520 moves in the heart cam groove 530. At the same time, the coil spring 510 is compressed between the pressing plate 222 of the slider 200 and the inner side surface of the housing recess 130a. Further, the front edge of the pair of window portions 211a of the slider 200 presses the contact portions 740a and 740b. As a result, the inclined plates 730a and 730b of the position regulating spring 700a700b are elastically deformed, and the contact portions 740a and 740b are displaced outward. When the edge on the near side of the pair of window portions 211a passes over the contact portions 740a and 740b, the contact portions 740a and 740b are returned inward by the return force of the inclined plates 730a and 730b of the position regulating spring 700a700b. To do.

  When the small card 10 is located at the card insertion position, it is inserted into the connection space between the contact portions 330 and 430 of the first and second contacts 300 and 400 as shown in FIG. Thereby, the small card 10 is elastically held between the contact portions 330 and 430 of the first and second contacts 300 and 400. At the same time, the electrode 13 of the small card 10 elastically contacts the contact portion 330 of the first contact 300. Therefore, stable contact between the contact portion 330 and the electrode 13 can be achieved, and chattering can be prevented from occurring even when the card connector C receives an impact or vibration from the outside.

  At this time, the other end portion of the hook pin 520 is fitted into a predetermined portion of the heart cam groove 530 and locked. As a result, the slider 200 is locked at the card insertion position. Further, the distal end portion of the first switch piece 610 is pressed by the guide block 800 a that moves together with the slider 200, and comes into contact with the distal end portion of the second switch piece 620. And both front-end | tip parts are accommodated in the notch part of the rear wall part 104a of the body 100a. As a result, a signal indicating that the slider 200 is positioned at the card insertion position is output to the electronic device through the substrate. In this way, the small card 10 is connected to the card connector C.

  When the small card 10 is located at the card insertion position, the state where the pair of both side position restricting pieces 120b and the central position restricting piece 110b are in contact with the electrode surface of the small card 10 is maintained. As a result, the small card 10 is restricted from moving upward from the front end portions of the both-side position restricting pieces 120b and the central position restricting piece 110b, and a predetermined load or more due to elastic contact with the small card 10 is the first contact. It is designed not to run over 300.

  Thereafter, when the small card 10 is further pushed from the card insertion position in the card insertion direction, the slider 200 further moves from the card insertion position in the card insertion direction. Thereby, the other end portion of the hook pin 520 moves in the heart cam groove 530, and the engagement between the other end portion and the predetermined portion of the heart cam groove 530 is released.

  Then, the pressing plate 222 of the slider 200 is pressed in the card ejection direction by the urging force of the coil spring 510. Thereby, the slider 200 moves in the card ejection direction. And the front-end | tip part of the base board 221 of the slider 200 contact | abuts to the wall surface of the near side of the accommodation recessed part 130a. Thereby, the slider 200 is positioned at the card ejection position. At this time, the edge on the near side of the pair of window portions 211a of the slider 200 passes over the contact portions 740a and 740b, and the contact portions 740a and 740b are engaged with the pair of window portions 211a. In this state, the small card 10 is pulled out from the first and second openings 106a and 107a.

  The small card 10 is inserted into the slot 105a through the first and second openings 106a and 107a of the body 100a in a state where the electrode surface is directed downward (that is, the small card 10 is in a direction other than a predetermined normal direction). Then, both end surfaces in the width direction of the small card 10 are respectively guided by the pair of upper guide portions 213 of the slider 200 and the contact portions 740a and 740b of the position regulating springs 700a and 700b.

  At this time, the electrode surface of the small card 10 is biased upward by the card biasing spring 214 of the slider 200. Thereby, the small card 10 moves upward.

  Thereafter, when the small card 10 is further inserted into the back side of the slot 105a, the lower surface of the small card 10 sequentially comes into contact with the pair of both side position restricting pieces 120b and the central position restricting piece 110b of the cover 100b, and the small card is thus described. 10 insertion postures are kept substantially horizontal.

  At the same time, as shown in FIG. 6, the other end in the width direction of the card body 11 of the small card 10 presses the first locking portion 213 a 1 of the upper locking arm 213 a of the slider 200 outward. As a result, the upper locking arm 213a is elastically deformed outward, and the tip of the upper locking arm 213a is displaced outward. Accordingly, the second locking portion 213a2 of the upper locking arm 213a is locked to the other end portion of the protruding piece 750a of the position regulating spring 700a. In this way, the slider 200 is locked to the position regulating spring 700a, and the slider 200 is prevented from sliding from the card ejection position to the card insertion position.

  For this reason, even if the small card 10 is further inserted into the back side of the slot 105a and the upper guide surfaces 820a and 820b of the guide blocks 800a and 800b are respectively pressed by both corners of the small card 10, the sliding movement of the slider 200 is performed. Therefore, the further insertion of the small card 10 into the slot 105a is prevented.

  The large card 20 is inserted into the slot 105a through the first and second openings 106a and 107a of the body 100a in a state where the electrode surface is directed downward (that is, the large card 20 is in a direction other than a predetermined normal direction). Then, the end surfaces of the pair of flange portions 22 of the large card 20 are respectively guided by the pair of edge portions 170b of the cover 100b and the pair of lower guide portions 211 of the slider 200, and the card body 21 of the large card 20 Both end surfaces of the upper end portion are respectively guided by the pair of upper guide portions 213 of the slider 200.

  At this time, the upper surface of the pair of flange portions of the large card 20 abuts with the pair of step portions 212 of the slider 200 while the electrode surface of the large card 20 is biased upward by the card biasing spring 214 of the slider 200. For this reason, the upward movement of the large card 20 by the biasing force of the card biasing spring 214 is prevented.

  At the same time, as shown in FIG. 7, the end surfaces of the pair of flange portions 22 of the large card 20 abut on the contact portions 740 a and 740 b of the position regulating springs 700 a and 700 b, and the upper end portion of the card body 21 of the large card 20. Is in contact with the first locking portion 213a1 of the upper locking arm 213a of the slider 200.

  At this time, the abutting portions 740a and 740b are abutted against and pressed against the end surfaces of the pair of flange portions 22, and the inclined plates 730a and 730b of the position regulating springs 700a and 700b are elastically deformed outward, so that the abutting portions 740a and 740b Is displaced outward. When the contact portions 740a and 740b are displaced outward in this manner, the engagement between the contact portions 740a and 740b and the pair of window portions 211a of the slider 200 is released. In this state, the large card 20 is elastically sandwiched between the contact portions 740a and 740b, and the position of the large card 20 is restricted to the above-described center position of the slot 105a. Further, due to the displacement of the contact portion 740a, the protruding piece 750a of the position regulating spring 700a is displaced outward, and the entire protruding piece 750a is accommodated in the notch portion 144a of the body 100a.

  At the same time, the first locking portion 213a1 of the upper locking arm 213a is brought into contact with and pressed against one end surface of the upper end portion of the card body 21, and the upper locking arm 213a is elastically deformed outward, and the upper locking arm 213a. However, since the protrusion 750a of the position restricting spring 700a is also displaced outward, the second locking portion 213a2 of the upper locking arm 213a and the other end of the protruding piece 750a are displaced. Locking is avoided.

  Thereafter, when the large card 20 is further inserted into the back side of the slot 105a, the upper surface of the large card 20 (that is, the surface opposite to the electrode surface) is the pair of both side position restricting pieces 120b and the center position restricting piece. 110b sequentially contacts. In other words, the large card 20 has its electrode surface biased by the card biasing spring 214 and its upper surface abutting against the pair of both side position restricting pieces 120b and the center position restricting piece 110b, so that the insertion posture thereof is substantially reduced. It is kept horizontal and is arranged at a height corresponding to the connection space. Further, when the pair of both side position restricting pieces 120b and the center position restricting piece 110b are in contact with the upper surface of the large card 20, one side portion of the rear end surface of the large card 20 in the width direction is pushed when the card is inserted. As a result, the large card 20 is prevented from rotating in the circumferential direction, and the large card 20 is also prevented from swinging in the width direction around the tip of the card biasing spring 214. Thereby, the play at the time of insertion of the large sized card | curd 20 is prevented.

  Thereafter, when the large card 20 is further inserted into the back side of the slot 105a, the front ends of the pair of flange portions 22 of the large card 20 come into contact with the lower guide surfaces 830a and 830b of the guide blocks 800a and 800b, respectively. As a result, the large card 20 is oriented straight along the card insertion direction at the center position in the slot 105a. At this time, the lower locking arm 211b of the slider 200 fits into the locking recess 22a of the large card 20 and locks the large card 20.

  Thereafter, when the large card 20 is further inserted into the back of the slot 105a, the lower guide surfaces 830a and 830b of the guide blocks 800a and 800b are pressed by the pair of flange portions 22 of the large card 20, respectively. As a result, the slider 200 moves from the card ejection position to the card insertion position together with the large card 20. At the same time, the guide protrusions 850a and 860b of the guide blocks 800a and 800b move along the pair of guide rails 130a of the body 100a.

  At this time, one end of the hook pin 520 rotates in the through hole 221 b of the slider 200, and the other end of the hook pin 520 moves in the heart cam groove 530. At the same time, the coil spring 510 is compressed between the pressing plate 222 of the slider 200 and the inner side surface of the housing recess 130a. Further, when the edge portion on the near side of the pair of window portions 211a of the slider 200 passes over the contact portions 740a and 740b, the contact portions 740a and 740b are pressed toward the outside by the edge portions. As a result, the inclined plates 730a and 730b of the position regulating spring 700a700b are further elastically deformed, and the contact portions 740a and 740b are displaced outward. Thereafter, the contact portions 740a and 740b are displaced inward by the restoring force of the inclined plates 730a and 730b, and the end surfaces of the pair of flange portions 22 of the large-sized card 20 are elastically sandwiched again.

  When the large card 20 is located at the card insertion position, it is inserted into the connection space between the contact portions 330 and 430 of the first and second contacts 300 and 400 as shown in FIG. Accordingly, the large card 20 is elastically sandwiched between the contact portions 330 and 430 of the first and second contacts 300 and 400. At the same time, the electrodes 23 of the large-sized card 20 are in elastic contact with the contact portions 430 of the second contacts 400, respectively. Therefore, stable contact between the contact portion 430 and the electrode 23 can be achieved, and chattering can be prevented from occurring even when the card connector C receives an impact or vibration from the outside.

  At this time, the other end portion of the hook pin 520 is fitted into a predetermined portion of the heart cam groove 530 and locked. As a result, the slider 200 is locked at the card insertion position. Further, the distal end portion of the first switch piece 610 is pressed by the guide block 800 a that moves together with the slider 200, and comes into contact with the distal end portion of the second switch piece 620. And both front-end | tip parts are accommodated in the notch part of the rear wall part 104a of the body 100a. As a result, a signal indicating that the slider 200 is positioned at the card insertion position is output to the electronic device through the substrate. In this way, the large card 20 is connected to the card connector C.

  When the large card 20 is located at the card insertion position, the state where the pair of both side position restricting pieces 120b and the central position restricting piece 110b are in contact with the upper surface of the large card 20 is maintained. As a result, the movement of the large-sized card 20 on both sides of the position restricting pieces 120b and the central position restricting piece 110b from the leading end is restricted, and a load exceeding a predetermined level due to elastic contact with the large-sized card 20 is applied to the first contact 300. It is designed not to hang on.

  Thereafter, when the large card 20 is further pushed from the card insertion position in the card insertion direction, the slider 200 further moves from the card insertion position in the card insertion direction. Thereby, the other end portion of the hook pin 520 moves in the heart cam groove 530, and the engagement between the other end portion and the predetermined portion of the heart cam groove 530 is released.

  Then, the pressing plate 222 of the slider 200 is pressed in the card ejection direction by the urging force of the coil spring 510. Thereby, the slider 200 moves in the card ejection direction. And the front-end | tip part of the base board 221 of the slider 200 contact | abuts to the wall surface of the near side of the accommodation recessed part 130a. Thereby, the slider 200 is positioned at the card ejection position.

  At this time, the edge on the near side of the pair of window portions 211a of the slider 200 passes over the contact portions 740a and 740b. Thereby, the contact portions 740a and 740b are pressed toward the outer side by the edge portions. Then, the inclined plates 730a and 730b are further elastically deformed, and the contact portions 740a and 740b are displaced outward. Thereafter, due to the restoring force of the inclined plates 730a and 730b, the contact portions 740a and 740b are displaced inward, and elastically contact the end faces of the pair of flange portions 22 of the large card 20 through the pair of windows 211a. In this state, the large card 20 is pulled out from the first and second openings 106a and 107a.

  An attempt is made to insert the large card 20 into the slot 105a through the first and second openings 106a and 107a of the body 100a in a state where the electrode surface is directed upward (that is, the large card 20 is in a direction other than the normal direction). The front ends of the pair of flange portions 22 of the large card 20 come into contact with the pair of protrusions 160a of the body 100a. For this reason, erroneous insertion of the large card 20 upside down is prevented.

  In the case of such a card connector C, when the small card 10 is inserted into the slot 105a of the body 100a in a direction other than the normal direction, the first locking portion 213a1 of the upper locking arm 213a of the slider 200 is used as the small card. 10 is pressed against the other end of the card body 11, the upper locking arm 213a is elastically deformed outward, and the second locking portion 213a2 is the other end of the protruding piece 750a of the position regulating spring 700a. It is locked to. That is, when the small card 10 is inserted into the slot 105a in a direction other than the normal direction, the slider 200 is caught by the position regulating spring 700a at the card discharge position, so that the card 200 is moved from the card discharge position to the card insertion position. Slide movement is prevented. Therefore, the user of the card connector C can feel that the small card 10 is caught by the slider 200 during the insertion process, and can visually recognize the state in which the small card 10 protrudes from the slot 105a. It can be recognized that it has been inserted in a wrong direction.

  On the other hand, even when the large card 20 is to be inserted into the slot 105a of the body 100a in a direction other than the normal direction, the distal ends of the pair of flange portions 22 of the large card 20 are paired with the pair of protrusions 160a of the body 100a. Therefore, the large card 20 is prevented from being erroneously inserted.

  In addition, when the small card 10 is inserted into the slot 105a through the second opening 107a of the body 100a in the proper orientation, the both end surfaces of the small card 10 are respectively guided by the contact portions 740a and 740b of the position regulating springs 700a and 700b. At the same time, the lower surface of the small card 10 is urged upward by the card urging spring 214 of the slider 200, and the small card 10 is pushed upward. That is, even if the small card 10 is erroneously inserted into the lower space of the slot 105a, the small card 10 is pushed up to a predetermined position, and both end surfaces of the small card 10 are regulated by the upper guide portions 213, respectively. It has become. For this reason, when the small card 10 is erroneously inserted into the lower space of the slot 105a, the small card 10 moves in the width direction in the lower space, and the contact between the electrode 13 of the small card 10 and the first contact 300 occurs. It is possible to prevent the positional deviation from the portion 330.

  Further, when the small card 10 is inserted into the slot 105a through the second opening 107a of the body 100a in a direction other than the normal direction, both end surfaces of the small card 10 are in contact portions 740a of the position regulating springs 700a and 700b. , 740b, the lower surface of the small card 10 is biased upward by the card biasing spring 214 of the slider 200, and the small card 10 is pushed upward. As described above, when the other end portion of the card body 11 of the slider 200 presses the first locking portion 213a1 of the upper locking arm 213a of the slider 200 outward, the second locking portion 213a2 is positioned. The restriction spring 700a is locked to the other end of the protruding piece 750a. Accordingly, it is possible to prevent erroneous insertion of the small card 10 in the direction other than the normal direction through the second opening 107a of the body 100a.

  The card connector C is not limited to the above-described embodiment, and can be arbitrarily changed in design as long as it meets the gist of the claims. Therefore, in the case of a card connector to which two or more cards can be connected, it is possible to provide two or more locking arms, each designed to prevent erroneous insertion in a direction other than a predetermined direction. Each part will be described below. In addition, it is a schematic diagram which shows the example of a design change of the latching arm of this card connector, Comprising: (a) is a figure which shows a 1st example and (b) shows a 2nd example.

  The housing 100 has the body 100a and the cover 100b. However, the present invention is not limited to this, and any housing may be used as long as it has a slot into which at least one card can be inserted. For example, a single resin injection molded product can be used as the housing.

  The design of the first and second openings 106a and 107a can be arbitrarily changed. That is, the width dimensions of the first and second openings can be made the same. Even in this case, as described above, if the lower guide portion, the step portion, and the upper guide portion are provided at both end portions of the slider, problems such as insertion of a large card from the first opening can be prevented. it can. The first opening may be an entrance dedicated to a small card, and the second opening may be an entrance dedicated to a large card. Also, the first and second openings can be made one opening.

  Whether or not the position regulating springs 700a and 700b are provided is arbitrary. Further, any position restricting spring may be used as long as it is a position restricting means that abuts on both end faces of the large card in the width direction and can restrict the movement of the large card in the width direction. Therefore, it is sufficient that there is at least one position restricting means, and there is no need to be elastically deformable outward. Further, the position restricting spring can be provided at both end portions of the slider instead of being provided at the lower portion of both wall portions in the width direction of the slot of the housing.

  The projecting piece 750a can be arbitrarily changed as long as it can function similarly. That is, it is possible to change the design so that a part of the position regulating means fulfills the function of the projecting piece 750a. Further, in place of the position restricting means, it is possible to provide the housing with a concave portion or a convex portion in which the second locking portion of the locking arm can be locked.

  Although the slider 200 is made of a metal plate, it is not limited to this. For example, it may be a resin injection molded product. Although both end portions of the slider body 210 are bent to form the lower guide portion 211, the step portion 212, and the upper guide portion 213, the lower guide portion 211, the step portion 212, and the upper guide portion 213 are provided.

And a pair of second edges that are provided on both sides of the second opening and the distance between them is slightly larger than the width of the large card, and between the first and second edges. It is preferable that a structure is provided that includes a pair of step portions that are respectively provided and that can contact the upper surfaces of both end portions in the width direction of the large card. That is, the first edge portion replaces the upper guide portion 213, the second edge portion replaces the lower guide portion 211, and the step portion replaces the step portion 212. At this time, the position regulating springs 700a and 700b can be elastically deformed in the width direction, and the distance between the contact portions 740a and 740b is substantially the same as the distance between the first edge portions. Is preferred.

  Of course, the housing is provided with the first edge, the second edge, and a step, and the first edge, the second edge, and the step at both ends of the slider in the card insertion direction. It is also possible to provide a lower guide part, a step part and an upper guide part in

  The upper locking arm 213a is a leaf spring whose tip is bent into a hook shape, but is not limited to this, and is convex toward the card and is engaged with the locking recess of the card. The first locking portion that can be stopped, and can be locked to a concave portion, a convex portion provided in the housing, or a position restricting means provided in the housing that is convex in the opposite direction of the first locking portion. As long as it has a certain 2nd latching | locking part, it is possible to change a design arbitrarily. For example, as shown in FIG. 19 (a), the tip of the upper locking arm 213a ′ is bent toward the card and then bent to the opposite side, and both bent portions are first and second locking portions 213a1. '213a2' may be used, or one end of the tip of the substantially T-shaped upper locking arm 213a '' may be a first locking portion 213a1 '' and the other end may be a second locking portion 213a2 ''. It is also possible to do.

  The card biasing spring 214 can be arbitrarily changed as long as it is a biasing means that can bias the small and large cards inserted into the lower space of the slot through the second opening upward. . For example, an elastic body such as an elastic rubber or a spring attached to the slider body 210 can be used as the urging means. A plurality of the urging means can be provided on the slider body 210. The urging means can be provided not on the slider but on the housing. In this case, it is preferable that the urging means is provided on the front side of the slider located at the card ejection position of the housing.

  Although the first and second contacts 300 and 400 are disposed in the upper space and the lower space of the slot 105a, respectively, the present invention is not limited to this. That is, when the positions of the electrodes of the small and large cards do not overlap each other, the first and second contacts can be arranged in the upper space or the lower space of the slot. Therefore, the card connector according to the present invention is not limited to a card connector in which small and large cards are inserted with their electrode surfaces upside down as in the above embodiment.

  Whether or not the eject mechanism 500 is provided is arbitrary. Also, another eject mechanism can be used. Specifically, as long as it is provided with a biasing means such as a rubber member for discharging the card or a spring member other than the coil spring, and a locking means for locking the card at the insertion position, any type is possible. You may use. In addition, as the ejection mechanism, a manually operated mechanism that ejects a card with an operation piece provided in the housing can be used.

  Whether or not the position detection switch 600 is provided is arbitrary. The position detection switch can be replaced by a magnetic switch, a tact switch, or the like.

  Whether or not the guide blocks 800a and 800b are also provided is arbitrary. The upper and lower guide surfaces of the guide block are arcuate tapered surfaces, but can be arbitrarily changed as long as they are tapered surfaces that gradually increase inward. Therefore, it is also possible to use linear tapered surfaces as the upper and lower guide surfaces. This guide block can be provided integrally with the slider.

  Although the card connector has been described as being inserted into the small card 10 that is a micro SD card and the large card 20 that is a memory stick micro card, the present invention is not limited to this. The small and large cards need only have at least different width dimensions.

  About the shape of each member, a constituent material, and an arrangement | positioning location, as long as the function similar to the said Example is realizable, it can change arbitrarily.
