The quality of harness materials directly affects the quality of harness. The selection of harness materials is related to the quality and service life of harness. Remind you that you must not be greedy for cheapness in the selection of wire harness products. Cheap wire harness products may use inferior wire harness materials. How to distinguish the quality of harness? Understand the material of the harness. The following is the information of harness material selection.
The harness is generally composed of wires, insulating sheath, wiring terminals and binding materials. As long as you know these materials, you can easily distinguish the quality of the harness.
1、 Material selection of terminal blocks
The copper used for terminal materials (copper parts) is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), in which brass accounts for a large proportion. In addition, different coatings can be selected according to different needs.
2、 Selection of insulating sheath
Sheath materials (plastic parts) commonly used materials mainly include PA6, PA66, ABS, PBT, PP, etc. Flame retardant or reinforcing materials can be added to plastics according to the actual situation to achieve the purpose of strengthening or flame retardant, such as adding glass fiber reinforcement, etc.
3、 Selection of harness wires
Select the corresponding wire material according to the different use environment.
4、 Selection of binding materials
Wire harness binding plays the role of wear resistance, flame retardancy, corrosion prevention, interference prevention, noise reduction and appearance beautification. Generally, binding materials are selected according to the working environment and space. The choice of binding materials usually includes tape, bellows, PVC pipe, etc.
