Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle charging guns, in particular to a liquid-cooled charging gun tail fixed wire structure. Background Art

[0002] At present, the tail of the charging gun is used in conjunction with a wire fixing claw, a wire locking ring and a tail cover. The wire locking ring is riveted and deformed, and the thread of the tail cover is matched with the thread of the gun body shell to tighten the wire fixing claw to achieve the purpose of tightening the cable. During the assembly process, although the wire locking ring is extruded and deformed using special tooling, the shape of the cable is an irregular circle, and the wire skin is easily damaged during the extrusion and deformation of the wire locking ring. The mating end of the wire fixing claw and the tail cover is generally made of plastic material and has a toothed structure. During the process of locking the tail cover and the shell thread, if the screwing force is too large, the toothed structure of the wire fixing claw will break, and the plastic of the tail cover and the shell will crack. If the screwing force is too small, the wire fixing claw cannot be tightened, and the purpose of fixing the cable cannot be achieved. Utility Model Content
