After the card connector 10 is mounted to the circuit board 70 (shown in Figure 1) The overheating reflow oven is used to solder the card connector 10 to the circuit board 70), but before the object 104 is inserted into the card space 101 for the first time, the first terminal 50 and the second terminal 60 are separated from each other, and the first terminal is The card pushing portion 503 of the card 50 extends into the card space 101 of the card connector 10, and the contact portion 504 of the first terminal 50 is located inside the contact portion 604 of the second terminal 60 and the pushed portion 603.

FIG. 5 illustrates a top view of the assembled card connector 10 of the present disclosure and partially inserted into the article 104. FIG. 6 illustrates a top view of the card connector 10 of the present disclosure assembled and fully inserted into the article 104. After the card connector 10 is assembled and mounted to the circuit board 70 (shown in FIG. 1), since the card pushing portion 503 of the first terminal 50 protrudes into the card space 101 of the card connector 10, when the object 104 is passed through When the card insertion slot 1011 is inserted into the card slot 101 of the card connector 10 for the first time, the left leading edge of the object 104 abuts against the card pushing portion 503 of the first terminal 50 in the card slot 101.

Since the card pushing portion 503 of the first terminal 50 extends obliquely inside the card space 101, when the object 104 continues to advance and pushes the card pushing portion 503 of the first terminal 50, the first terminal 50 is provided by the elastic portion 502. The elasticity moves from the inside of the card space 101 to the outside. In addition, the end 505 of the first terminal 50 abuts against the pushed portion 603 of the second terminal 60, and the pushed portion 603 extends obliquely toward the first terminal 50 and the card space 101. Therefore, when the end 505 of the first terminal 50 pushes the pushed portion 603 of the second terminal 60, the second terminal 60 is moved outward by the elasticity provided by the elastic portion 602, so that the end 505 of the first terminal 50 can pass the second The pushed portion 603 of the terminal 60, the contact portion 504 of the first terminal 50 can be moved from the inner side to the outer side of the contact portion 604 of the second terminal 60. Thereafter, the second terminal 60 is further biased into the card space 101 by the elasticity provided by the elastic portion 602. The direction of the movement moves back to reset.

Before the object 104 exits the card space 101, the contact portion 504 of the first terminal 50 is moved from the inner side to the outer side of the contact portion 604 of the second terminal 60 by the operations of FIGS. 5 and 6, and the object 104 is borrowed from the object 104. After the card is removed from the card slot 101, the contact portion 504 of the first terminal 50 is kept in contact with the contact portion 604 of the second terminal 60 by the elasticity provided by the elastic portion 502 of the first terminal 50, and is detected. Switch 40 is in a normally closed state. In the normally closed state, the card pushing portion 503 of the first terminal 50 is located within the card space 101, and the contact portion 504 of the first terminal 50 is located outside the contact portion 604 of the second terminal 60 and the two are kept in contact with each other.

When the object 104 or another object is once again inserted into the card space 101, the card pushing portion 503 of the first terminal 50 is pushed by the object 104 such that the contact portion 504 of the first terminal 50 is separated from the contact portion 604 of the second terminal 60. In the non-contact state (the detection switch 40 is in the off state), the detection function of the card connector 10 for inserting the object 104 into the card space 101 can be realized. In the embodiment of the present disclosure, the object 104 can be a SIM card, but the technology of the present disclosure can also use other tools to implement the operations shown in FIG. 5 and FIG. 6, and is not limited to the SIM card.

In short, before the object 104 is inserted into the card space 101 for the first time, the first terminal 50 and the second terminal 60 are separated from each other (as shown in FIG. 3). When the article 104 is first inserted into the card space 101, the object 104 pushes the first terminal 20 and the first terminal 20 pushes the second terminal 30 (as shown in FIG. 5). After the object 104 exits the card space 101, the first terminal 50 and the second terminal 60 are in contact with each other and are in common Closed state (as shown in Figure 6).

The advantages of the disclosed embodiment include: before the card connector is assembled to the circuit board, the first terminal and the second terminal of the detecting switch are in a state of being separated and not in contact; after the card connector is completely mounted on the circuit board, detecting The first terminal and the second terminal of the switch are moved to contact each other; by the above structural design, the detecting switch can be effectively maintained in a normally closed state without stress relaxation due to the manufacturing process. The contact pressure between the first terminal and the second terminal is weakened or even inaccessible, causing failure of the switch detection.
