The low-voltage wiring harness refers to the wires that connect the various electrical equipment inside the car. These wires are generally in a bundled state and exist in the form of a bundle, so they are called wiring harnesses. The low-voltage wiring harness is composed of wires, terminals, connectors, corrugated tubes, heat-shrinkable tubes, silicone rubber, etc. 60% of the faults in the electrical system of special vehicles are caused by the quality of the wiring harness, mainly due to functional failure, appearance failure, and protective failure.
Functional failure: The quality of terminal crimping and terminal plugging directly lead to the failure of an electronic control system of the vehicle.
Appearance failure: The wiring harness is protected by open bellows and wrapped and fixed with electrical insulating tape. The wiring harness is not beautiful, which directly affects the appearance of the vehicle.
Protection failure: The tail end of the branch harness connector is not protected, and problems such as water entering the inlet end of the connector will cause abnormal terminal connections.
The quality of the wire harness is directly related to the normal operation of the electrical system of the special vehicle. It is imperative to improve the production level of the wire harness and the reliability of the wire harness.
