And a waterproof member that allows pushing in the insertion direction.

  Since the card connector of the present invention includes a waterproof member that closes the pin insertion hole and surrounds the peripheral surface of the standing wall part, the highly reliable waterproof structure is realized. In addition, this waterproof member allows the slide bar to be pushed by the eject pin while being interposed between the eject pin and the slide bar when the eject pin is inserted into the pin insertion hole. For this reason, the card tray can be taken out by the eject pin without removing the waterproof member.

  Here, in the card connector of the present invention, the portion of the waterproof member that closes the pin insertion hole extends into the pin insertion hole from the front surface of the standing wall in the direction of insertion, and enters the pin insertion hole. It is preferable to form a bellows shape that is folded back in the direction toward the center in the direction and extended in the take-out direction, further in the direction toward the center in the radial direction, further in the direction of insertion, and closed in the insertion direction.

  By forming the portion of the waterproof member that closes the pin insertion hole into the above bellows shape, the eject pin can be smoothly inserted while maintaining the waterproof performance.

  Further, in the card connector of the present invention, the waterproof member has a shape that covers the entire area of the front surface of the standing wall portion by covering the pin insertion hole, bends to the circumferential surface of the standing wall portion, and surrounds the circumferential surface of the standing wall portion. Is preferred.

  When the waterproof member is formed in a cap shape that covers the entire area as described above, a waterproof structure with higher reliability is realized.

  According to the above-described present invention, a card connector having a highly reliable waterproof structure is realized.

Specifically, a portion 122a of the waterproof member 122 blocking the pin insertion hole 121c extends from the front surface of the standing wall portion 121b shown in FIG. 3 in the insertion direction (direction of arrow I) into the pin insertion hole 121c. Thus, the first portion 122b that has entered the pin insertion hole 121c is formed. The waterproof member 122 is further folded back from the first portion 122b toward the center of the pin insertion hole 121c to form a second portion 122c that extends in the take-out direction (direction of arrow E). The waterproof member 122 is further folded back in the direction from the second portion 122c toward the center of the pin insertion hole 121c, and extends again in the insertion direction (the direction of the arrow I) so that the tip is closed. 122d is formed. In the present embodiment, the portion 122a of the waterproof member 122 blocking the pin insertion hole 121c has a bellows shape composed of the first to third portions 122b, 122c, and 122d as described above.

  When the eject pin 50 is inserted, the portion 122a of the waterproof member 122 that closes the pin insertion hole 121c is pushed in the insertion direction (direction of arrow I) while breaking the bellows shape, and the slide bar 14 is pushed in. . When the eject pin 50 is extracted from the pin insertion hole 121c, the elastic member 122 returns to the original bellows shape by the elastic force of the waterproof member 122. Alternatively, even when the eject pin 50 is removed, the card bar 12 is not completely restored to the original bellows shape, but when the card tray 12 is inserted again, the slide bar 14 removes it from the back side (the direction of the arrow E). ) To return to the original bellows shape.

  Here, in this embodiment, the pin insertion hole 121c is a round hole, and the portion 122a of the waterproof member 122 blocking the pin insertion hole 121 is a concentric bellows. However, it is not necessary to have a concentric shape, and it may be a bellows or a waveform having different shapes vertically and horizontally. That is, any shape may be used as long as it is extended when the eject pin 50 is inserted and the slide bar 14 is pushed and the eject pin 50 is pulled out or when the card tray 12 is inserted again. Alternatively, the waterproof member 122 may be configured to use a rubber material that greatly expands when a force is applied, and push the slide bar 14 only by the expansion of the rubber material.
