New energy vehicle engine wire harness insulation sheath

Abstract

The invention discloses a new energy vehicle engine wire harness insulation sheath comprising a sheath base layer, a surface clad layer, an adhesive layer and a cover layer; one surface of the sheath base layer is evenly provided with recess ports; the other surface of the sheath base layer is evenly provided with protruding portions; the surface clad layer covers the sheath base layer surface with the recess ports; the adhesive layer is coated on the sheath base layer surface with the protruding portions; the cover layer is composited on the adhesive layer surface. The insulation sheath employs a multi-layer structure, and the pyramidal structure or cube structure are designed so as to increase the insulation sheath surface areas, thus providing wear resistant effect; the insulation coating is matched with the recess ports so as to increase the insulation sheath insulation effect; the compound adhesive layer can provide the surface adsorptivity for the insulation sheath.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and relates to a new energy vehicle engine wiring harness, in particular to an insulating sheath of a new energy vehicle engine wiring harness. Background technique [0002] With the increase of environmental pressure and the gradual shortage of oil resources, it is an inevitable trend in the development of the automobile industry to gradually replace traditional fuel vehicles with new energy vehicles. Currently, new energy vehicles mainly include hybrid vehicles, pure electric vehicles, fuel cell vehicles, gas cars and hydrogen-engined cars. Among them, hybrid electric vehicles and pure electric vehicles account for more than 90% of new energy vehicles, and they are the undisputed leading models. performance, low energy consumption and low emissions. The steady development of the new energy vehicle industry has also brought about continuous improvement in the quality and demand of ...

Problems solved by technology

Because the interior of the car is a very complicated small environment, there are many harsh environmental factors such as high temperature, high temperature difference, organic solvents, flammables, and disturbing noise on the car, especially the wiring harness caused by car bumps and vibrations. The mutual friction and pulling of the wire harness makes it easy for the car wiring harness to be damaged or broken, resulting in poor or even interrupted power transmission in the car. At the same time, the large current carried by the wiring harness is also likely to generate an interfering magnetic field, endangering the health of the surrounding human body and the sensitivity of instruments.
