Through the arrangement of the structure, the male end contact pin can be stably fixed in the socket.

In particular, the inner wall between the guide portion of the male pin and the contact portion forms a second converging opening. Through the arrangement of the structure, the second convergence opening can be used as a supporting stop surface for pushing and pressing the contact pin, an external operation tool acts on the position, and although the size of the connector is small and exquisite, the assembly work of the male contact pin can be very convenient.

Particularly, the other end of the buckling plate forms a pressing part, a rib is arranged at the position, below the pressing part, on the top plate of the plug, and a descending wedge body is formed by the rib towards the direction far away from the fulcrum. Through the arrangement of the structure, the rotation angle of the buckling part can be increased, and the plug can be conveniently separated from the connecting and accommodating groove of the socket.

Particularly, guide groove side strips are arranged on two sides of the wedge-shaped protruding portion, the guide groove side strips form a guide groove, and the wedge-shaped protruding portion can move in the guide groove and is in buckling fit with the buckling portion. Through the arrangement of the structure, the buckling part can be prevented from being separated from the side direction of the wedge-shaped bulge part.
