Then, in the second terminal 370, the bent portion 375 is moved downward by being pressed in the insertion direction to the memory card. As a result, the movable plate portion 375 is displaced downward (direction separated from the first terminal 360).

As shown in FIG. 12 and FIG. 13, the contact piece portion 372 moves downward in accordance with the displacement of the movable plate portion 375 downward. By the movement of this contact piece part 372, the 1st terminal 360 pressed by the upper regulation arm part 380 side is spaced apart from the convex part 382 of the regulation arm part 380. As shown in FIG.

When the memory card 200 is further inserted into the connector 300, in the second terminal 370, the bent portion 375 is further pressed in the insertion direction to be displaced downward.

As a result, the movable plate portion 373 also moves downward, and the contact piece portion 372 also moves downward (in a direction away from the first terminal 30).

Here, when the contact piece portion 372 is separated from the first terminal 360, the first terminal 360 swings around the proximal end portion, and the contact piece portion 372 is also the proximal end side of the movable plate portion 375. It moves downward by swinging around it. Accordingly, the contact piece portion 372 moves to be spaced apart while sliding with respect to the first terminal 360.

Then, as shown in FIG. 14, the contact piece part 372 is separated from the 1st terminal 360, and releases the pressed state to the said 1st terminal 360. FIG. Therefore, in the card detection switch 350, the contact state, that is, the connected state, between the first terminal 360 and the second terminal 370 is released.

As such, while the memory card 200 is inserted into the connector 300 and the contact piece portion 372 is completely separated from the first terminal 360, the first terminal 360 of the second terminal 370 is provided. ), The connection state is released. That is, the switches of the first terminal 360 and the second terminal 370 are in an open state, and the card detection switch 350 detects a card insertion state.

When the memory card 200 having the first switch 350A opened in this manner is inserted into the connector 300, the memory card 200 moves to the portion in which the second switch 350B is disposed in the side wall portion 314.

Then, in the second terminal 470, the bent portion 475 is moved downward by being pressed in the insertion direction to the memory card, and the movable plate portion 473 is also downward (direction separated from the first terminal 460). Displace.

FIG. 15 is a diagram showing the main components of the card detecting unit immediately before the second switch is turned OFF by the insertion of the memory card 200 in the connector according to the second embodiment of the present invention. As shown in FIG. 15, the contact piece portion 472 moves downward in accordance with the displacement of the movable plate portion 473 downward. The first terminal 460 pressed by the contact piece portion 472 by the movement of the contact piece portion 472 is separated from the convex portion 482 of the restricting arm portion 480.

When the memory card is inserted deep into the connector 300, the bent portion 475 is further pressed in the insertion direction and displaced downward in the second terminal 470.

As a result, the movable plate portion 473 also moves downward, and the contact piece portion 472 also moves downward (in a direction away from the first terminal 30) while sliding with respect to the first terminal 460. This state is shown in FIG.

As shown in FIG. 16, the contact piece portion 472 is separated from the first terminal 460 to release the pressed state of the first terminal 460. Accordingly, in the card detection switch 350, the contact state, that is, the connected state, between the first terminal 460 and the second terminal 470 is released.

In this way, the memory card 200 is mounted on the connector 300, so that while the contact piece 472 is completely separated from the first terminal 460, the memory card 200 is connected to the first terminal 460 of the second terminal 470. The connection state is released. That is, the switches of the first terminal 460 and the second terminal 470 are opened, and it is detected through the card detection switch 350 that the card is mounted.

In the card detection switch 350, the first switch 350A on the insertion port side having the first terminal 360 and the second terminal 370 detects card insertion and, at the same time, protects the card from being write-protected. Detect locked and unlocked status.

Even when foreign matter is caught in the contact portions of the first terminals 360 and 460 and the second terminals 370 and 470, foreign matters at the portions rubbing with each other can be removed by approaching / separating each other with friction. That is, contact cleaning between the first terminal and the second terminal of the card detection switch 350 can be performed.

Further, in the second terminals 370 and 470, the contact piece portions 372 and 472 are branched so as to be separated from the movable plate portions 373 and 473 of the terminal bodies 374 and 474, and the terminal pieces 374 and 474 are separated from each other. It is formed along the extension direction. As a result, a gap G (see FIG. 11) is provided between the contact piece portions 372 and 472 and the terminal main bodies 374 and 474. In addition, since the clearance between the contact piece 472 and the terminal main body 474 is provided in the same manner as the gap G between the contact piece 372 and the terminal main body 374, illustration thereof will be omitted. Therefore, foreign matter does not stay between each of the contact piece portion 372 and the terminal body 374, and between the contact piece portion 472 and the terminal body 474, thereby effectively excluding foreign matter in the connector, thereby effectively eliminating the first and second terminals. The contact state of each other can be made into a favorable contact state.

In the connector 300 of the second embodiment, the second terminals 370 and 470 are formed together with the housing 310 by insert molding, and the first terminals 360 and 460 are the restricting arm portions 380 and 480. Together with the switch contact 400.
