The quality of the wire harness material in the wire harness processing plant directly affects the quality of the wire harness, and the selection of the wire harness material is related to the quality and service life of the wire harness.

Remind everyone that in the choice of harness products, you must not be greedy for cheap. Cheap harness products may use inferior harness materials. How to distinguish the quality of the wire harness? Know the material of the wire harness. The following is the information of wire harness selection.

 

The wiring harness is generally composed of wires, insulating sheaths, terminals and wrapping materials. As long as you understand these materials, you can easily distinguish the quality of the wiring harness.

1. Material selection of terminal

The copper used for the terminal material (copper pieces) is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), of which brass accounts for a larger proportion. In addition, different coatings can be selected according to different needs.

Second, the choice of insulating sheath

The commonly used materials of sheath material (plastic parts) mainly include PA6, PA66, ABS, PBT, pp and so on. According to the actual situation, flame-retardant or reinforced materials can be added to the plastic to achieve the purpose of reinforcement or flame-retardant, such as adding glass fiber reinforcement.

Third, the choice of wire harness

According to the different use environment, select the corresponding wire material.

Fourth, the choice of dressing materials

Wire harness wrapping plays the role of abrasion resistance, flame retardancy, corrosion prevention, interference prevention, noise reduction, and appearance beautification. Generally, the wrapping material is selected according to the working environment and the size of the space. There are usually adhesive tapes, corrugated pipes, PVC pipes, etc. in the selection of wrapping materials.
