Selection of wire harness material
Selection of wire harness material
Harness material is good or bad, directly affecting the quality of the wiring harness, the choice of harness material, and the quality and service life of the wiring harness. Remind the majority of you, in the selection of wiring harness products, must not be greedy for cheap, cheap wiring harness products used may be inferior wiring harness materials. How to distinguish between the good and bad quality of the wiring harness? Understand the harness material will understand. The following is the wiring harness material selection information.
Wire harnesses are generally composed of wires, insulation sheaths, terminals, and wrap materials. As long as you understand these materials, you can easily distinguish between good and bad wiring harnesses.
A the terminal material selection
Terminal material (copper parts) with copper is mainly brass and bronze (brass hardness than bronze hardness is slightly lower), of which brass accounted for a larger proportion. In addition, according to different needs choose a different plating.
Second, the choice of the insulation sheath
Sheath material (plastic parts) commonly used materials are mainly PA6, PA66, ABS, PBT, pp, etc.. According to the actual situation in the plastic to add flame retardant or enhanced materials to enhance or flame retardant purposes, such as adding glass fiber reinforced.
Third, the choice of wire harness wire
According to the use of different environments, choose the appropriate wire materials.
Fourth, the choice of wrap material
Wire harness wrap plays a wear-resistant, flame retardant, anti-corrosion, to prevent interference, reduce noise, and beautify the appearance of the role, generally according to the working environment and space size choose the wrap material. The choice of wrapping materials is usually tape, corrugated pipe, PVC pipe, etc.
