The second conductive terminal 4 is inserted into the terminal groove from the rear wall of the insulating body, and the elastic contact portion 42 is located on the second surface 111 of the tongue plate and partially protrudes from the second surface 111 (see FIG. 4 ). The terminal positioning member 6 is used for inserting the terminal pins, which is helpful for the soldering of the terminals.

An inner surface of the side wall of the insulating body defines a receiving groove 134 on the first wall surface 131 closest to the bottom wall. A pair of detection terminals 5 are accommodated in the accommodation groove. The detection terminal includes a fixed terminal 51 and a movable terminal 52. The elastic protruding part of the movable terminal protrudes from the first wall surface 131, and can move to the inside of the receiving groove under the actuation of the docking connector to complete the overlapping part 522 at the front end and The front end 512 of the fixed terminal 52 is in contact.
