The movable contact portion 722 is configured by a torsion spring. Both ends of the torsion spring protrude slightly downward from the lower surface of the slide member 701. The protruding portion comes into contact with the fixed contact portion 222 provided on the housing 2 according to the position of the slide member 701.

  Next, an operation when each card is mounted on the connector 1 according to the present embodiment will be described. 20 to 26 are diagrams for explaining the operation when the card A is mounted on the connector 1 according to the present embodiment. 27 to 31 are diagrams for explaining the operation when the card B is mounted on the connector 1 according to the present embodiment. 32 to 36 are diagrams for explaining an operation when the card C is mounted on the connector 1 according to the present embodiment. 20 to 36, the cover member 3 is omitted for convenience of explanation.

  First, the operation when the card A is attached to the connector 1 according to the present embodiment will be described. FIG. 20 is a front view when the card A is inserted into the connector 1 according to the present embodiment. FIG. 21 is a perspective view when the card A is inserted into the connector 1 according to the present embodiment. 22 is a cross-sectional view of the connector 1 in the state shown in FIG. FIG. 23 is a perspective view when the card A is attached to the connector 1 according to the present embodiment. 24 is a cross-sectional view of the connector 1 in the state shown in FIG. Before the card A is inserted, the connector 1 is in the state shown in FIGS.

  As shown in FIG. 20, when the card A is attached to the connector 1 according to the present embodiment, the side and bottom surfaces of the card A are aligned with the first guide portion 206 provided in the housing 2. The card A is pushed into the connector 1. In this process of pushing into the connector 1, the leading end of the card A comes into contact with the contact surface 502 c of the actuator member 502 and the shutter member 501. As a result, the actuator member 502 rotates rearward, and the shutter member 501 rotates so as to fall backward. At this time, the contact surface 502c of the actuator member 502 is in a state of facing the left side surface of the card A as shown in FIG.

  When the card A is pushed in in this way, the card A advances from the upper side of the partition plate 6 to the rear side of the connector 1 as shown in FIGS. In this case, the partition plate 6 moves slightly downward, and pushes down the card B contacts 214 and 215 slightly on its lower surface. The portion corresponding to the card B contacts 214 and 215 on the lower surface of the partition plate 6 constitutes a pressing portion that pushes down the card B contacts 214 and 215. In this manner, the limited space in the connector 1 is effectively utilized by slightly pressing down the card B contacts 214 and 215 on the lower surface of the partition plate 6 as the card A is inserted.

  Further, as shown in FIG. 21, the right end portion of the card A abuts on the first abutment surface 704 of the slide member 7 at a position above the partition plate 6 and the engagement of the slide member 7. The convex portion 710 a of the stopper piece 710 engages with a concave portion formed on the right side surface of the card A. When the convex portion 710a engages with the concave portion of the card A, the position of the card A with respect to the slide member 7 is determined, and thereafter, the slide member 7 and the card A move together. Note that when the front end of the card A comes into contact with the first contact surface 704, one end on the front side of the locking member 703 is near the end on the rear side of the linear guide groove 717 of the guide groove 711. Has been placed.

  When the card A is further pushed in from the state shown in FIGS. 21 and 22, the card A contact 212 enters the lower surface of the card A and is formed on the lower surface of the front end portion of the card A as shown in FIGS. 23 and 24. Contact the contact pad. 23 and 24 show a state where the card A is pushed to the position on the rearmost side of the connector 1 and the hand is released. In this state, one end on the front side of the locking member 703 is locked to the locking portion 715.

  In addition, when the slide member 7 moves rearward as the card A is inserted in this way, in the detection mechanism 8 of the connector 1 according to the present embodiment, the detection mechanism provided on the lower side of the slide member 7. 8 detects the mounting state of the card A. Specifically, the attachment of the card A is detected based on the position of the movable contact portion 722 attached to the lower surface of the slide member 7 with respect to the fixed contact portion 222 provided in the housing 2.

  In the detection mechanism 8, when the slide member 7 moves to the position shown in FIGS. 23 and 24, the movable contact portion 722 and the fixed contact portion 222 come into contact with each other and become conductive. On the other hand, before reaching the position shown in FIGS. 23 and 24, the movable contact portion 722 and the fixed contact portion 222 are not in contact with each other, and are brought into a non-conductive state. The detection mechanism 8 detects the mounting state of the card A according to the conduction state and non-conduction state between the movable contact portion 722 and the fixed contact portion 222. As described above, since the detection mechanism 8 is configured by the fixed contact portion 222 provided in the housing 2 and the movable contact portion 722 provided in the slide member 701, the card A can be surely increased without increasing the number of components. Can be detected. The same applies to the mounted state of the card B and the card C.

  Further, in the connector 1 according to the present embodiment, the detection mechanism 8 disposed on the left side of the partition plate 6 detects whether or not the card A is mounted and the state of the card A write prevention function. Here, of the detection operations of these detection mechanisms 8, the operation for detecting the state of the write protection function of the card A will be described.

  25 and 26 are perspective views for explaining the operation when detecting the state of the write protection function of the card A in the detection mechanism 8 of the connector 1 according to the present embodiment. 25 and 26, a part of the housing 2 is omitted for convenience of explanation. FIG. 25 shows the connector 1 in the state shown in FIG. 21, and FIG. 26 shows the connector 1 in the state shown in FIG. FIG. 25 and FIG. 26 show a state in which the write prevention function in the card A is on (state in which writing is locked). That is, the case where the write prevention switch SW is switched to the position on the front side of the connector 1 is shown.

  The state of the write protection function of the card A is detected by a detection mechanism 8 disposed on the front side of the connector 1. As shown in FIG. 25, when the write prevention switch SW has not reached the detection mechanism 8, the left end of the card A comes into contact with the contact portion 802. And the rear side of the plate-like part 801 is inclined downward by pushing down the rear side end of the contact part 802. In this case, both ends of the movable contact portion 803b are in contact with the fixed contact portions 803a arranged at the front and rear, respectively, and the fixed contact portion 803a and the movable contact portion 803b are in a conductive state. When the card A is positioned at a predetermined mounting position, the write prevention switch SW comes into contact with the contact portion 802, and when the fixed contact portion 803a and the movable contact portion 803b are in a conductive state, the write prevention function Is recognized to be off.

  When the card A is pushed in from this state, as shown in FIG. 26, the write prevention switch SW reaches the position of the detection mechanism 8, but does not come into contact with the contact portion 802. Since the abutting portion 802 is not pushed down, the plate-like portion 801 is urged upward by the urging force of the movable contact portion 803b and is in a substantially horizontal state. In this case, one end on the rear side of the movable contact portion 803b is separated from the fixed contact portion 803a, and the fixed contact portion 803a and the movable contact portion 803b are in a non-conductive state. When the card A is located at a predetermined mounting position, the write prevention switch SW does not come into contact with the contact portion 802, and when the fixed contact portion 803a and the movable contact portion 803b are in a non-conductive state as described above, It is recognized that the prevention function is on.

  Note that when the write prevention function of the card A is in an off state (a state in which writing is not locked), the write prevention switch SW is switched to a position on the rear side of the connector 1. In this case, when the card A is attached to the connector 1, the write prevention switch SW contacts the contact portion 802 and pushes down the contact portion 802, so that both ends of the movable contact portion 803b are front and rear. The fixed contact portion 803a and the movable contact portion 803b are in a conductive state. Therefore, even in this case, it is recognized that the write protection function is in the off state. The detection of the presence or absence of the card A is detected in the same manner by using the leading end portion of the card A by the detection mechanism 8 disposed on the rear side of the connector 1.

  Next, an operation when the card B is attached to the connector 1 according to the present embodiment will be described. FIG. 27 is a front view when the card B is inserted into the connector 1 according to the present embodiment. FIG. 28 is a perspective view when the card B is inserted into the connector 1 according to the present embodiment. FIG. 29 is a cross-sectional view of the connector 1 in the state shown in FIG. FIG. 30 is a perspective view when the card B is attached to the connector 1 according to the present embodiment. FIG. 31 is a cross-sectional view of the connector 1 in the state shown in FIG. Before the card B is inserted, the connector 1 is in the state shown in FIGS.

Push card B into the box. In this case, unlike the case where the card A is inserted, the leading end of the card B does not come into contact with the contact surface 502c of the actuator member 502 and the shutter member 501, so that they do not rotate. When the card B is inserted, the card B can be easily cut out by bringing the left side surface of the card B into contact with the end of the first guide portion 206 disposed on the left side. It can be adjusted to the portion 501b.

  The end portion of the first guide portion 206 disposed on the left side of the card B to be inserted constitutes a first side guide portion that guides the side surface of the card B, and is on the right side of the notch portion 501b of the shutter member 501. A second side guide portion that guides the side surface of the card B at the end portion is configured. Since the side surface of the card B is guided by the first side surface guide portion and the second side surface guide portion as described above, the contact pad for the card B can be surely moved without shifting the contact pad of the card B in the side surface direction. 215 can be connected.

  When the card B is pushed in as described above, the card B advances below the partition plate 6 to the rear side of the connector 1 as shown in FIGS. In this case, the partition plate 6 moves slightly upward, and pushes up the card A contact 212 slightly at the rear portion of the opening 603. The rear portion of the opening 603 constitutes a push-up portion that pushes up the card A contact 212. In this case, the tip of the card A contact 212 is accommodated in the opening 603 of the partition plate 6. By accommodating the card A contact in the opening 603 in this way, a situation in which the tip end portion of the card A contact 212 is damaged is prevented.

  As shown in FIG. 28, the right end of the card B is in contact with the second contact surface 705 of the slide member 7 at a position on the lower side of the partition plate 6 and on the lower side of the slide member 7. The protrusion 222 a of the locking piece 222 provided on the card engages with the recess formed on the lower surface of the card B. Since the convex portion 222a is engaged with the concave portion of the card B, the slide member 7 and the card B are moved together thereafter. Note that when the leading end of the card B comes into contact with the second contact surface 705, one end on the front side of the locking member 703 is disposed in the vicinity of the rear side end of the linear guide groove 717 of the guide groove 711.

  When the card B is inserted, as shown in FIG. 29, the upper surface is guided by the lower surface of the notch 501b provided in the shutter member 501 and the lower surface of the partition plate 6, and the lower surface is the housing. 2 is guided by a support surface 217c of a protective plate 217 provided on the second plate. Further, when the lower surface is pushed downward, a guide piece 223 provided in the housing 2 guides. These positional relationships are configured to support the front end of the card B in a state where it is slightly inclined downward. For this reason, the card B is pushed into the connector 1 with the tip end inclined downward.

  When the card B is further pushed in from the state shown in FIG. 28 and FIG. 29, the card B contacts 214 and 215 enter the lower surface of the card B and are formed on the lower surface of the front end portion of the card B as shown in FIG. Contact with the contact pads. At this time, since the urging force of the urging piece 302 of the cover member 3 is applied to the card B via the partition plate 6, the contact pressure between the contact pad of the card B and the contacts 214 and 215 for the card B is reduced. It becomes possible to make it higher. 30 and 31 show a state where the card B is pushed to the position on the rearmost side of the connector 1 and the hand is released. In this state. One end on the front side of the locking member 703 is locked to the locking portion 715. Even when the card B is mounted as described above, the card B is held in a state where the tip end portion is inclined downward as in the case of insertion. Even in this held state, the upper surface of the card B is guided by the lower surface of the notch portion 501b of the shutter portion 501 and the lower surface of the partition plate 6, so that the contact pad of the card B and the contact 214 for the card B , 215 is intended for connection stability.

  Next, an operation when the card C is mounted on the connector 1 according to the present embodiment will be described. FIG. 32 is a front view when the card C is inserted into the connector 1 according to the present embodiment. FIG. 33 is a perspective view when the card C is inserted into the connector 1 according to the present embodiment. 34 is a cross-sectional view of the connector 1 in the state shown in FIG. FIG. 35 is a perspective view when the card C is attached to the connector 1 according to the present embodiment. 36 is a cross-sectional view of the connector 1 in the state shown in FIG. Before the card C is inserted, the connector 1 is in the state shown in FIGS.

  As shown in FIG. 32, when the card C is attached to the connector 1 according to the present embodiment, the side surface and the lower surface of the card C are aligned with the second guide portion 207 provided in the housing 2. The card C is pushed into the connector 1. In this case, unlike the case where the card A is inserted, the leading end portion of the card C does not come into contact with the contact surface 502c of the actuator member 502 and the shutter member 501, so that they do not rotate.

  When the card C is pushed in in this way, as shown in FIG. 33, the leading end of the card C enters the lower side of the pair of projecting pieces 606 provided on the partition plate 6 and lifts the partition plate 6. Then, the lower side of the partition plate 6 proceeds to the rear side of the connector 1. In this case, like the insertion of the card B, the partition plate 6 moves slightly upward, and pushes up the card A contact 212 slightly at the rear side portion of the opening 603. In this case, the tip of the card A contact 212 is accommodated in the opening 603 of the partition plate 6. By accommodating the card A contact in the opening 603 in this manner, the situation in which the tip end portion of the card A contact 212 is damaged is prevented in the same manner as when the card B is inserted.

  Further, the lower surface of the front end portion of the card C is in contact with the protective plate 217 provided on the housing 2, and the rear side end portion of the protective plate 217 is slightly opposed against the urging force of the support piece 221 that supports this from the lower side. Press down. As a result, the card C contact 216 approaches the card C in the groove 218 formed in the protection plate 217.

  Further, the right end portion of the card C comes into contact with the third contact portion 706 of the slide member 701 at a position below the partition plate 6. Note that when the leading end of the card C comes into contact with the third contact portion 706, one end on the front side of the locking member 703 is arranged in the vicinity of the rear side end portion of the linear guide groove 717 of the guide groove 711. Has been.

  When the card C is further pushed in from the state shown in FIGS. 33 and 34, the lower surface of the card C further pushes down the protective plate 217 as shown in FIGS. As a result, the card C contact 216 is exposed from the groove 218 of the protection plate 217. The exposed card C contact 216 enters the lower surface of the card C and comes into contact with a contact pad formed on the lower surface of the front end of the card C. At this time, since the urging force of the urging piece 302 of the cover member 3 is applied to the card C through the protruding piece 606 of the partition plate 6, the contact between the contact pad of the card C and the card C contact 216 is made. The pressure can be increased. 35 and 36 show a state where the card C is pushed to the position on the rearmost side of the connector 1 and the hand is released. In this state. One end on the front side of the locking member 703 is locked to the locking portion 715.

  In the connector 1 according to the present embodiment, the partition plate 6 has an opening 603 that accommodates the tip end portion of the card A contact 212 that moves downward as the card A is inserted, and the card B that is inserted. And a push-up portion that pushes up the card A contact 212 to a position at which the card A contact 212 does not contact the card B through the opening 603. As a result, even when the height of the connector is reduced, contact between each card and a non-corresponding contact can be avoided to prevent damage to the contact.

  In the connector 1 according to the present embodiment, the partition plate 6 is moved downward as the card A is inserted, and is moved upward as the card B is inserted. As described above, since the partition plate 6 is moved up and down with the insertion of the card A and the card B, a part of the card mounting space corresponding to the card A and the card B can be shared. It is possible to realize a reduction in the height of the 1 itself.
