Abstract

This application relates to a waterproof connector, comprising a connector body, an outer end of which has a positioning protrusion adapted to the outer wall of a battery pack, connecting holes on both sides of the positioning protrusion, an annular groove on the outer end of the connector body, and a hollow protective cap on the outer end of the connector body. The protective cap has a sliding groove adapted to the side of the outer end of the connector body, and locking protrusions on both sides of the sliding groove that fit the annular groove. The connector body has a connector post extending through both ends, and the outer end face of the connector post has a insertion groove. This utility model belongs to the field of battery pack technology. Through the multiple sealing design of the protective cap, sealing gasket, and sealing ring, it effectively prevents moisture intrusion; the flat hole structure and flat positioning structure prevent the connector post from rotating; and the limiting protrusion and annular groove ensure stable connection.
