Mobile WebSiteAutomotive wire, also known as low voltage wire, it is different from ordinary household wire. Ordinary household wire is copper single core wire, there is a certain hardness. The car wires are copper multi-core cord, some soft as thin as hair, and even dozens of soft copper wire wrapped in plastic insulation (PVC), soft and not easily broken.
Due to the special nature of the automotive industry, automotive wiring harness testing process is more special than the other ordinary wiring harness.
Harness is the circuit connecting the electrical equipment wiring components, from the insulation sheathing, terminals, wires and insulation materials such as bandaging.
First, the composition of the wire harness
1. Harness
In order to facilitate the installation, maintenance, to ensure that electrical equipment can work under the harshest conditions, the whole vehicle electrical equipment used by different specifications, different colors of the wire through reasonable arrangements, to be integrated, and the wire bundled with insulating material Bunch, so complete and reliable.
2. Wire cross-sectional area and color scale of the normal choice
(1) the correct choice of wire cross-sectional area
The electrical equipment on the car selects the cross-sectional area of the wire to be used, based on the size of the load current. Long working hours of electrical equipment can choose the actual current carrying capacity of 60%; short-term working electrical equipment available wire current carrying capacity of 60% -100%.
(2) wire color choice
In order to facilitate identification and repair, the wire harnesses in different colors.
In order to annotate in the circuit diagram conveniently, the color of the lead wire is all indicated by the letter, its representative color is annotated in each circuit diagram.
