Description

Connecting wire of wire harness, wire harness and vehicle Technical Field The present disclosure relates to the technical field of vehicles, and more particularly, to a connection wire of a wire harness, and a vehicle. Background The connecting wire of the wire harness is normally provided with a sealing plug for sealing the connector, preventing invasion of moisture, dust, grease and other external impurities, and simultaneously ensuring that the wire harness connector can keep stable electrical performance and improving the safety of the connector. The sealing plug of the part wire harness connector is hung with the sheath by arranging the tail cover at one end of the sheath, so that the sealing plug is prevented from falling off, and the sealing failure is avoided. However, when the connector tail cover is hung with the connector sheath, a certain gap is always reserved between the tail cover and the sealing plug, and in the use process, if external impact, extrusion or vibration and other external forces are applied, the sealing plug can possibly displace towards the interface of the connector, so that the sealing effect is easily lost, and the leakage risk is increased.
