[0002] The wiring harness is the overall service equipment for a certain load source group, and it mainly plays the role of control, transmission and connection. The connection between wiring harnesses and wiring harnesses and wiring harnesses and electrical components generally adopts connectors. The wiring harness connector is an important component for connecting various electrical and electronic equipment. The connector is used between blocked or isolated circuits in the circuit to build a bridge of communication to allow current to flow, thereby enabling the circuit to achieve its intended function.

[0003] Since the connector is provided with exposed electrode plugs and wiring structures inside, in order to prevent water from entering and causing short-circuit damage to the electrodes, the connector is required to have good structural sealing. For the sealing structure, existing connectors mostly use a ring-gasket fitting sealing structure. Due to the structural characteristics, the ring gasket has poor sealing performance for the inner ring. During use, water can easily penetrate through the gap in the inner ring of the ring gasket, resulting in poor structural sealing. Therefore, a wire harness tension sealing connector is proposed.
