Abstract

The invention discloses a manufacturing method of a high-voltage wire harness protective cover for a new energy vehicle, which includes: ① peeling off the insulating sheath of the high-voltage wire harness, and the crimping frame should hold at least 88% of the wire; ② wrapping the inner ring bushing outside the high-voltage wire harness , use the hexagon crimping assembly to crimp the hexagon evenly, and wrap the outer sleeve again; ③Tensile strength test, the test range is 27-32mm per minute; ④Place the crimped terminal after the tensile test in the mold Injection molding; this invention achieves the purpose of protecting the high-voltage wire harness protective sleeve of new energy vehicles from moisture, chemicals and harmful gases.

Description

technical field [0001] The invention belongs to the field of spare parts of new energy vehicles, and relates to a method for manufacturing a high-voltage wire harness protective cover of a new energy vehicle. Background technique [0002] Almost 50% of all defects on new energy vehicles are caused by weather-induced aging and corrosion damage to electronic components. Especially under extreme temperature conditions, the protection of electronic components against moisture, chemicals and harmful gases is an indispensable prerequisite for avoiding such system failures. Contents of the invention [0003] In view of this, the present invention aims to overcome at least one of the above-mentioned defects in the prior art, and proposes a simple structure, high pressure resistance, and effective protection against moisture, chemical substances and harmful gases under extremely severe temperature conditions. A method for manufacturing a high-voltage wire harness protective cover ...
