1. Wire: This is one of the most basic components in wiring harness design, and the material may vary depending on the usage scenario and the required performance of the harness. Some common types of wires used in automotive wiring harnesses are aluminium wires, polyethylene wires, PVC wires, etc., which are suitable for different environments and functional requirements. For example, aluminium wires are commonly used for main power and hitch wires because of their good electrical conductivity and corrosion resistance.
2. injection moulding materials: injection moulding materials are the key materials to ensure the stability and safety of wire connection. In the automotive wiring harness, commonly used injection moulding materials are PVCPVC, PE, TPETPE, etc. PVCPVC is a commonly used wire protection material, but the environmental performance is insufficient; PE does not contain halogen, environmental protection is better, but the cost is higher; TPETPE has good flexibility and cold resistance, the cost is higher.
3. Insulating materials: insulating materials are an indispensable part of the wiring harness design, they can protect the wires from the effects of the external environment, and to ensure that the insulation between the wires. In automotive wiring harnesses, commonly used insulation materials are PVC, SR-PVC, cellular polyethylene, EPDM, TPE/TPR, PE, low and high density polyethylene, cellular or foam polyethylene, PU, low-smoke flame-retardant copolymers, polypropylene (PP) and porous (foam) polypropylene, FEP, TFE, polytetrafluoroethylene, ETFE Teflon, PVDF Kainal, ECTFE Harald, IRR/PVC, XLPE, vinyl plastics, etc. Environmental conditions such as operating temperature and humidity need to be considered when selecting insulation materials.
4. Wrapping materials: Wrapping materials are used in wire harness design to protect the wires and prevent them from fraying. In automotive wiring harnesses, commonly used wrapping materials are nylon, polyester, polypropylene and so on.
5. connectors: connectors are important components used to connect wires in the harness design. In automotive wiring harnesses, the commonly used types of connectors are plugs, sockets, terminals, and so on.
6. fixing material: fixing material is the material used to fix the wiring harness in the wiring harness design. In the automotive wiring harness, commonly used fixed materials are ties, tapes, snaps, etc..
7. other materials: in addition to the above materials, the harness design may also use other materials, such as thermoplastic elastomers, polyester fibres and so on.
Overall, there are a wide variety of materials commonly used in wiring harness design, and choosing the right material is the key to ensuring the performance and reliability of the wiring harness.
