The quality of the electronic wiring harness material directly affects the quality of the electronic wiring harness. The choice of electronic wiring harness material is related to the quality and service life of the electronic wiring harness. So when choosing an electronic wiring harness product, do not be greedy for cheap, cheap electronic wiring harness products may use inferior electronic wiring harness materials. How to distinguish the quality of seat belts? The electronic wiring harness is generally composed of wires, insulating sheaths, terminals and binding materials. As long as you understand these materials, you can easily distinguish the quality of the electronic wiring harness.
1. Material selection of terminal equipment
The copper used in terminal materials (copper parts) is mainly brass and bronze (brass is slightly lower in hardness than bronze), of which brass has a larger specific gravity. In addition, different coatings can be selected according to different needs.
2. Selection of insulating sheath
Sheath materials (plastic parts) commonly used materials are PA6, PA66, ABS, PBT, PP, etc. According to the actual situation, flame retardant or reinforcing materials can be added to the plastic to achieve the purpose of reinforcing or flame retardant, such as adding glass fiber reinforcement.
3. Selection of wire harness
According to different use environment, choose the corresponding wire. It is recommended to use copper material with good conductivity and low loss.
4. Selection of decorative materials
Wire harness binding has the functions of wear resistance, flame retardant, anticorrosion, anti-interference, noise reduction, and beautifying the appearance. Generally, the bonding material is selected according to the working environment and the size of the space. In the choice of bonding materials, there are generally adhesive tape, corrugated pipe, PVC pipe, etc.
