The second insulating case 3 slides to move into The card slot 312 further completes the latch between the first connector 100 and the second connector 200. In particular, referring to FIG. 10 and FIG. 14, in the process of the first connector 100 and the second connector 200, the first connector 100 is taken as an example, because the two terminals of each of the conductive terminals 2 are There is a distance between the front end of the contact portion 232a and the inner wall surface of the first abutting portion 11, but the two guiding portions 232b are respectively bent forward by the two second contact portions 232a and obliquely bent, and the second connector 200 The structure is also the same, so that the two opposite conductive terminals 2 can slide along the guiding portion 232b during assembly without being stuck to each other.

Referring to FIG. 22, FIG. 23 and FIG. 24, when the first connector 100 and the second connector 200 are docked, the card 132 of the first connector 100 is located in the card slot 312 of the second connector 200 by the card. The block 132 is engaged in the card slot 312 to prevent the first connector 100 from retreating, so that the first connector 100 and the second connector 200 are relatively fixed to stabilize the connection. Moreover, as shown in FIG. 24, the first contact portions 223 of the two opposite conductive terminals 2 of the first connector 100 and the second connector 200 respectively abut the second contact portions 232a of the conductive terminals 2 Four contact regions are formed between the two conductive terminals 2 in contact, thereby providing a more stable and more reliable electrical connection, and improving the efficiency and stability of long-term use.

Since the first connector 100 and the second connector 200 use the conductive terminals 2 of the same structure and shape, the same mold can be used, which not only saves manufacturing costs, but also reduces the number of parts and inventory problems.

In summary, through the first connector 100 and the second connector 200 using the same structure and shape of the conductive terminal 2, the manufacturing cost can be saved, and the two first contact portions 223 of the butted conductive terminals 2 are respectively in contact with the two second contact portions 232a of the butted conductive terminals 2 at the two conductive Four contact areas are formed between the terminals 2, thereby providing a more stable and more reliable electrical connection, and improving the performance and stability of long-term use. Moreover, the structural design of the conductive terminal 2 can prevent the conductive terminal 2 and the conductive terminal 2 or the conductive terminal 2 and the cable 7 from being entangled during the manufacturing process to avoid damage of the conductive terminal 2. Moreover, the first connector 100 and the second connector 200 can prevent mis-insertion by the cooperation of the two keys 14 and the two key grooves 313, so that the object of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the patent application scope and the patent specification of the present invention are still It is within the scope of the patent of the present invention.
