▎ 摘　　要

NOVELTY - The wiring harness module (100) has a conductor element (110) and an insulating element (120) that encloses the conductor element. The conductor element includes a conductor (111). Each of the conductors connects an input conductive joint (130) and an output conductive joint (140). The electrical connection of conductors of different wiring harness modules is realized by connecting the input conductive joint and output conductive joint of different wiring harness modules. The plating layer is made of gold, silver, nickel, tin, zinc, tin-lead alloy, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy. The bottom layer is made of gold, silver, nickel, tin, tin-lead alloy and zinc. The surface layer is made of gold, silver, nickel, tin, tin-lead alloy, silver-antimony alloy, palladium, palladium-nickel alloy, graphite silver, graphene silver and silver-gold-zirconium alloy. USE - Wiring harness module used in combined wiring harness (claimed) for connecting electric appliance and power supply of vehicle such as train and ship. ADVANTAGE - The number of wiring harness modules is reduced, so as to reduce the volume of the wiring harness and reduce the cost. The structure of the wiring harness module is simple and connection operation is very convenient. The combination connection of wiring harness modules is firmer by connecting the insulating portions of different wiring harness units, and wiring harness module is not easy to break off or loose, which improves the reliability of the safety connection. The production efficiency and qualification rate are improved. The wiring harness module is convenient to maintain. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a combined wiring harness for connecting electric appliance and power supply of vehicle. DESCRIPTION OF DRAWING(S) - The drawing shows an isometric view of the structure of the wiring harness module.
