[0025] Referring to Figure 2 , the conducting wire of high pressure wire harness in the inside of shell 1 adopts spiral arrangement;Mounting ring 4, mounting post 2 and fixed column 5 adopt rubber material, for preventing electric leakage;

[0026] Specifically, when vehicle passes through bumpy road and produces vibration, the conducting wire of spiral arrangement can effectively disperse the stress generated by vibration, compared with traditional parallel arrangement, it can reduce the mutual extrusion and friction between conducting wire, reduce the risk of conducting wire abrasion and insulation layer damage caused by long-term vibration, improve the service life of wire harness, rubber has elasticity, when vehicle vibrates or is impacted, the mounting ring 4, mounting post 2 and fixed column 5 of rubber material can play the role of buffering and shock absorption.
