As shown in fig. 1 to 10, the conductive terminal 10 of the connector includes a terminal body 1, a stopper structure 2 and a stopper structure 3.

The terminal body 1 is a hollow structure, and the terminal body 1 has a first end 11 and a second end 12 opposite to each other. The baffle structure 2 is located in the terminal body 1, and the edge of the baffle structure 2 is abutted to the inner wall of the terminal body 1 so as to block the injection molding liquid. The stop formation 3 is located on a side of the flap formation 2 remote from the first end 11, and the stop formation 3 is adapted to support the flap formation 2 in a first direction, which is a direction in which the first end 11 points towards the second end 12. Since the injection liquid may enter the terminal body from the first end 11 during injection molding, in order to prevent the flap structure 2 from being washed away by the injection liquid, the stopper structure 3 needs to be disposed on a side of the flap structure 2 away from the first end 11.

In the conductive terminal 10 of the connector that this embodiment provided, set up separation blade structure 2 in terminal body 1, and separation blade structure 2's edge can with terminal body 1's inner wall butt, make separation blade structure 2 can block the liquid of moulding plastics, prevent that the liquid of moulding plastics from flowing into terminal body 1 by terminal body 1's first end 11, the electrically conductive performance of conductive terminal 10 of connector has been guaranteed, and, through setting up dog structure 3, can support separation blade structure 2, in order to prevent that separation blade structure 2 is pushed away by the liquid of moulding plastics and warp, separation blade structure 2's function has been guaranteed.

Alternatively, the stop structure 3 is stamped and formed from the outer wall of the terminal body 1 in the second direction, it being understood that the side wall of the terminal body 1 is provided with a groove, which forms the stop structure 3. Wherein the second direction is a thickness direction of the terminal body 1. For example, when the terminal body 1 has a cylindrical shape, the second direction may be a radial direction of the terminal body 1. The stopper structure 3 may be a block structure fixed to the inner wall of the terminal body 1, which is not limited in this embodiment.

Further, the conductive terminal 10 of the connector may include a plurality of stopper structures 3, and the plurality of stopper structures 3 are uniformly and alternately disposed along the circumference of the terminal body 1 to support the stopper structures 2 uniformly, thereby improving the supporting effect of the stopper structures 3.

The blocking piece structure 2 is formed in this way, so that the probability that the blocking piece structure 2 is separated from the terminal body 1 due to stress can be reduced. Also, as shown in fig. 4 or 5, when the flap structure 2 is formed in this manner, the through-hole 13 exists in the terminal body 1.

The first portion 61 has a cross-sectional dimension greater than that of the second portion 62, i.e., the connecting tab 6 is wider at a portion near the first end 11 and narrower at a portion away from the first end 11 to facilitate the engagement of the connecting tab 6 with the PCB board 30. Specifically, the first portion 61 can be stably and firmly contacted with the PCB, and the second portion 62 can be welded with a contact point on the PCB, so as to improve the connection effect between the conductive terminal 10 of the connector and the PCB 30.
