[0078] In summary, the utility model clip pin high current connector contacts with the male terminal in a clamping manner, and a terminal assembly is arranged in the shell, and the pointed wedge-shaped end of the terminal assembly can wedge into the inner clamping opening of the clip assembly. Therefore, when the male terminal is pressed against the outer clamping opening of the clip assembly, the clip assembly is forced to move inward, and the pointed wedge-shaped end of the rear rod-shaped terminal forces the outer clamping opening of the clip assembly to clamp the male terminal, so that the clip pin assembly and the male terminal are in stable contact.
