Wire harness processing generally consists 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.
The quality of the wire harness processing material directly affects the quality of the wire harness, and the choice of the wire harness material is related to the quality and service life of the wire harness. The choice of online bundle products must not be cheap, and the cheap wire harness products may use inferior wire harness materials. How to tell the quality of the wire harness? Understand the material of the wire harness processing will understand.
Material selection of terminal blocks: The copper used for the terminal material (copper parts) is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), and brass accounts for a large proportion. In addition, different coatings can be selected according to different needs.
Selection of wire harness processing wires: Select the appropriate wire material depending on the environment in which it is used.
Selection of insulating sheath: The material commonly used for sheath material (plastic parts) mainly includes PA6, PA66, ABS, PBT, pp, etc. Flame retardant or reinforcing materials can be added to the plastic according to the actual situation to achieve the purpose of strengthening or flame retardant, such as adding glass fiber reinforcement.
The choice of dressing materials: wire harness dressing to wear, flame retardant, anti-corrosion, anti-interference, reduce noise, beautify the appearance of the role, generally according to the working environment and space to choose the dressing material. Tape, bellows, PVC pipe, etc. are usually used in the selection of the dressing material.
