The card holding part has a card insertion slot into which a memory card is inserted. The cantilever contacts are arranged so as to face the card insertion slot, and can make electrical contact with the on-surface connection terminals provided in the memory card.

  Furthermore, the memory card connector according to Patent Document 1 includes a swing slider, a tension coil spring, and a guide rod. The swing slider is disposed so as to be displaceable with respect to a side plane on one side of a recess formed in the housing for receiving a memory card. The swing slider has a heart-shaped cam groove formed on the upper surface.

  The tension coil spring has hooks at both ends, one hook is locked to the housing, and the other hook is locked to the swing slider. The tension coil spring urges the swing slider in the anti-insertion direction of the memory card and can correct the tilted state of the swing slider. One end of the guide rod is connected to the heart-shaped cam groove, and the other end is rotatably held by the housing.

  And the 1st guide, the cylindrical protrusion, and the 2nd guide are formed in the side plane of one side of a crevice. The first guide extends toward the card insertion slot. The columnar protrusion is formed at the end of the first guide. The second guide is formed close to and parallel to the first guide, and is disposed closer to the center of the recess than the first guide.

  On the other hand, a counterbore slot, a groove, and a recess are formed on the bottom surface of the swing slider. The counterbore oblong hole guides the cylindrical protrusion and regulates the stop position of the swing slider urged by the tension coil spring. The groove is formed at the end of the counterbore elongated hole and is slidably coupled to the first guide. Since the groove opens in a V shape toward the end, the swing slider can swing. The recess is slidably coupled to the second guide so that the linear motion of the swing slider can be secured when the swing slider moves against the tension coil spring.

  Further, the swing slider has an L-shaped first claw and a second claw. The L-shaped first claw is brought into contact with the insertion side corner of the memory card. The 2nd nail | claw can enter / exit into the recessed part formed in the side surface of a memory card. In the memory card, one corner is formed at a right angle, the other corner forms a slope, and the second claw is biased by a tension coil spring so as to be retracted from the card holder. ing.

In the memory card connector according to Patent Document 1, a swing slider having a heart-shaped cam groove is used as a cam, a guide rod is used as a follower, and the cam and the follower are relative to each other. The cam apparatus which moves is comprised. In the memory card connector disclosed in Patent Document 1, when one end of the guide rod is locked to the starting point of the heart-shaped cam groove, the second claw is urged by the tension coil spring to hold the card.

The pivot shafts 16a and 16b are supported by a pair of pivot holes 15a and 15b provided on one wing of the window 1m, so that the door 15 is rotatably supported so that the passage 15 can be opened and closed. The cover 2 has an opening 2g for easily viewing the window 1m.

  In FIG. 5, the housing 1h is provided with a card detection switch 7 on the side wall 11a. The card detection switch 7 includes a contact plate 71 and a contacted plate 72. When the card 8 is in the mounting position, it is pushed by the side surface of the card 8 and the tip 71a of the contact plate 71 comes into contact with the contacted plate 72 to be electrically connected. When the card 8 is removed, the contact plate 71 returns and separates from the contacted plate 72, and is electrically cut off. In this way, the presence or absence of the card 8 is detected.

  Next, the operation will be described while capturing the configuration of the connector 1 according to the present invention.

  In FIG. 5, the connector 1 has a slider 4 having a heart-shaped cam groove 41 as a cam serving as a moving node, a guide rod 6 as a driven node, and the slider 4 and the guide rod 6 are relatively displaced between the cam and the driven node. The cam device is configured. When one end 6a of the guide bar 6 is locked to the starting point 41a of the heart-shaped cam groove 41, the slider 4 is urged by the compression coil spring 5 so that the locking claw 46 is retracted from the recess 8c. It is arranged to be inclined.

  Next, in FIG. 1, when the card 8 is inserted into the housing 1 h, the inclined side of the slider 4 is corrected against the urging force of the compression coil spring 5 by the oblique side 8 b of the card 8 pushing the engagement piece 45. As a result, the locking claw 46 rotates and enters the recess 8c. When the card 8 is further inserted, the slider 4 moves parallel to the insertion direction following the card 8 against the urging force of the compression coil spring 5, and one end 6 a of the guide bar 6 is formed in the heart-shaped cam groove 41. Move the journey (see FIG. 5).

  Next, the slider 4 is fixed in position by the one end 6a of the guide rod 6 engaging with the V-shaped groove 41v formed at the apex of the heart-shaped cam groove 41 (see FIG. 5). And the attachment state of the card | curd 8 is maintained because the latching claw 46 enters into the recessed part 8c. At this time, the tip 47a of the protruding piece 47 moves from the window 1m, and the door 16 hangs down by its own weight and closes the passage 15 (see FIG. 1).

  Next, when the card 8 of the housing 1h is pushed in the insertion direction, one end 6a of the guide rod 6 is released from the V-shaped groove 41v and moves to the locus of the return stroke, and the slider 4 is biased by the compression coil spring 5. Thus, it moves parallel to the anti-insertion direction (see FIG. 5). In the process in which the one end 6a of the guide rod 6 returns to the return stroke or the starting point 41a of the heart-shaped cam groove 41, the card 8 is dragged by the engagement piece 45 and moves in the anti-insertion direction.

  Next, when one end 6a of the guide rod 6 returns to the starting point 41a of the heart-shaped cam groove 41 and is locked, the slider 4 is biased by the compression coil spring 5 and the locking claw 46 is recessed. Inclination is arranged (corrected) so as to avoid from 8c. Then, the card 8 is removed from the recess 1 a by the biasing force of the compression coil spring 5 connected to the slider 4. The protruding piece 47 pushes up the door 16 and closes the window 1m (see FIG. 1).

  Thus, when the card | curd 8 is inserted in the housing 1h and the front-end | tip part 47a of the protrusion piece 47 exists in the position away from the window 1m, the door 16 hangs down with dead weight and closes the channel | path 15. On the other hand, when the card 8 is removed from the housing 1h, the slider 4 returns and the protruding piece 47 pushes up the door 16 to close the window 1m. And the cover 2 can visually recognize easily that the door 16 has closed the window 1m from the opening 2g. It can also be easily recognized that the slider 4 has moved and the door 16 has opened the window 1m.

  Next, the configuration and operation of the card connector according to the second embodiment of the present invention will be described. In contrast to the connector 1 according to the first embodiment shown in FIGS. 1 to 5, FIGS. 6 to 9 show a connector 10 according to the second embodiment.

  The connector 1 according to the first embodiment and the connector 10 according to the second embodiment have substantially the same configuration and operation. Therefore, in the second embodiment shown in FIGS. 6 to 9, only the difference from the first embodiment will be described, and the description similar to the first embodiment may be omitted.

  6 to 8, the housing 10h has a passage 15 and a window 10m. The passage 15 penetrates toward the opening 1b so that the protruding piece 47 can advance and retreat. It is preferable that the passage 15 has a margin so that it can advance and retreat even when the protruding piece 47 is inclined. The window 10m opens in a rectangular shape on the front surface of the housing 10h and is exposed at the edge of the passage 15.

  In FIG. 6, when the card 8 is inserted into the housing 10h and the tip end surface 47b of the projecting piece 47 is at a position away from the window 10m, the inside of the window 10m is a cavity, and the slider 4 is positioned relative to the housing 10h. You can see that it is moving. On the other hand, when the card 8 is removed from the housing 10h, the front end surface 47b of the projecting piece 47 closes the window 10m, so that it can be visually confirmed that the slider 4 is restored. The action of the slider 4 when the card 8 is inserted and removed is the same as in the first embodiment.

  Thus, the connector 10 can identify the advance / retreat position of the slider 4 by the state change in which the tip surface 47b of the protruding piece 47 opens and closes the window 10m. And since the window 10m is easily exposed from the outside, it is easy to confirm that the slider 4 has returned correctly.

  The hue of the housing 1h and the door 16 according to the first embodiment of the present invention may be easily different from each other, and the hue of the housing 10h and the slider 4 of the second embodiment may be different. For example, in the first embodiment, the housing 1h is black and the door 16 is green, so that identification is easy. At this time, when green can be visually recognized from the window 1m, it can be identified that the card 8 is not inserted. In the second embodiment, the housing 10h is black and the slider 4 is green, so that the identification is easy. At this time, when green can be visually recognized from the window 10m, it can be identified that the card 8 is not inserted.
