Is the wiring harness easily damaged? Three aspects should be started when investigating the cause

Wire harness cable is a combination of strings of wires and cables that are widely used to transmit information signals or operating signals. It consists of terminals at both ends and a middle cable. A set of wiring harness cables has four contacts, so the probability of failure is also increasing. In the eyes of many engineers, the wire harness cable is a kind of easily damaged connector. After discovering the wiring harness failure, we can consider the incentives from three aspects to avoid later.

1) Natural damage: The wire bundle has been used beyond the service life, the wire is aging, the insulation layer is broken, and the mechanical strength is significantly reduced. Causes short circuits, open circuits, grounding and other abnormalities between the wires, causing the wire bundle to burn out.

2) Harness damage caused by electrical equipment failure: When electrical equipment is overloaded, short-circuited, grounded, and other faults, the wiring harness may be damaged.

3) Man-made damage: When workers assemble or repair auto parts, metal objects crush the wire bundle, causing the wire bundle insulation to break. The positive and negative leads of the battery are connected reversely, and when the circuit is repaired, they are connected randomly, and the wire harness is cut randomly. Cause abnormal operation of electrical equipment.
