The wiring harness fuse holder is a wiring part connecting various electrical equipment in automobile circuit, which is composed of insulation sheath, wiring terminal, wire and insulation wrapping material.Let us follow the wiring harness manufacturers together to understand it.

composition of the wiring harness

1. Electrical wiring harness

In order to facilitate the installation, maintenance, to ensure that the electrical equipment can work in the worst conditions, the electrical equipment used in the whole car with different specifications, different colors of the wire through reasonable arrangement, it is integrated into a bundle, and bundled with insulation materials, so that it is complete and reliable.

2. Normal selection of wire sectional area and color standard

The electrical equipment on the vehicle selects the cross-sectional area of the wire according to the load current. Electrical equipment that works for a long time can choose 60% of the actual current-carrying capacity of the wire; Short - time operation of electrical equipment can be 60%-100% of the actual carrying capacity of the wire.

main causes of wiring harness line failure

The reasons are as follows:

1. natural damage

The use of wire harness exceeds the use period, so that wire aging, broken insulation layer, mechanical strength dropped significantly, causing a short circuit between wires, circuit breakers, iron, etc., resulting in wire harness burn out. Oxidation or deformation of wire harness terminals may cause poor contact, which may cause abnormal operation of electrical equipment.

2. The wiring harness is damaged due to the failure of electrical equipment

When the electrical equipment overload, short circuit, rail and other faults, may cause wiring harness damage.

3. human failure

When assembling or repairing auto parts, metal objects will crush the wire harness and break the insulation layer of the wire harness. Improper position of wiring harness; The lead position of the electrical equipment is wrong; Battery positive and negative leads are connected inversely; When repairing circuit fault, disorderly connection, disorderly cutting wire harness and wires, etc., can cause the abnormal work of electrical equipment, and even burn out the wiring harness.
