First, the car wiring harness
  Automotive wiring harnesses (automotive wiring harnesses) that enable physical connection of power to the vehicle and various electrical components. The harness is distributed throughout the car. If the engine is likened to the heart of a car, then the wire harness is the neural network system of the car. It is responsible for the information transfer between the various electrical parts of the vehicle.

The system for manufacturing automotive wiring harnesses is roughly divided into two categories.
  (1) In the European and American countries, including China, the TS16949 system is used to control the manufacturing process.
  (2) Mainly in Japan: Toyota and Honda have their own systems to control the manufacturing process.
Second, the introduction of common materials for automotive wiring harness
   1. Wire (low voltage wire, 60-600V)
   Type of wire:
   National standard line: QVR, QFR, QVVR, QBV, QBVV, etc.
   Japanese standard line: AV, AVS, AVSS, AEX, AVX, CAVUS, EB, TW, SHE-G, etc.
   German standard line: FLRY-A, FLRY-B, etc.
   American standard line: SXL, etc.
   Commonly used specifications are wires with a nominal cross-sectional area of 0.5, 0.75, 1.0, 1.5, 2.0, 2.5, 4.0, 6.0, etc.

2, sheath
    The sheath (plastic shell), usually made of plastic, inserts the wire of the pressed terminal into it to ensure the reliability of the connection. The materials mainly include PA6, PA66, ABS, PBT, PP, etc.

3, the terminal
     A formed hardware component is crimped onto a wire to connect different wires to transmit signals, and is divided into a male terminal, a female terminal, a ring terminal, and a round terminal.

The material is mainly brass and bronze (the hardness of brass is slightly lower than that of bronze), and brass accounts for a large proportion.
2, sheath accessories: waterproof plug, blind plug, sealing ring, locking piece, buckle, etc.
   Generally used to form a connector with a sheath terminal
3, wire harness through hole rubber parts
   Wear-resistant, waterproof, sealed and so on. It is mainly distributed at the interface between the engine and the cab, at the interface between the front compartment and the cab (two at the left and right), at the interface between the four doors (or the back door) and the compartment, and at the inlet of the fuel tank.
4, cable tie (snack)
  An original is usually made of plastic to secure the harness to the car. There are straps and bellows lock straps.
 5, pipe
Split bellows, PVC heat shrinkable tube, glass fiber tube. Braided tubes, wound tubes, etc. Used to protect the harness. (classified by diameter)
1 bellows
Bellows generally account for about 60% or more in wire bundle dressing. The main feature is that the wear resistance is good, and the high temperature resistance, flame retardancy and heat resistance are good in the high temperature zone. The temperature of the bellows is between -40 and 150 °C. Its material is generally divided into PP and PA2. PA material is superior to PP material in flame retardant and wear resistance; however, PP material is stronger than PA material in bending fatigue resistance.
2PVC heat shrinkable tube The function of PVC pipe is similar to that of bellows. The PVC pipe has good flexibility and bending resistance, and the PVC pipe is generally closed, so the PVC pipe is mainly used for the branch of the wire harness to make the wire smoothly transition. The heat resistance temperature of the PVC pipe is not high, generally below 80 °C.
 6, tape
 Production tape: Wrap the wire harness surface. (divided into PVC, sponge tape, cloth tape, paper tape, etc.). Quality Marking Tape: Used to identify defects in the production of the product.
    The tape acts as a bundle, wear, insulation, flame retardant, noise reduction, marking, etc. in the wire bundle, and generally accounts for about 30% in the wrapping material. The wiring harness tape is generally divided into three types: PVC tape, air-laid cloth tape and cloth tape. PVC tape has good wear resistance and flame retardancy; the temperature resistance is around 80 °C, the noise reduction is not good, and the price is relatively cheap. The flannel tape and the cloth tape material are PET. The banding property and the noise reduction of the flannel tape are the best, and the temperature resistance is about 105 °C; the abrasion resistance of the cloth tape is the best, and the temperature resistance is up to 150 °C. The common disadvantage of flannel tape and cloth tape is that it is not flame retardant and expensive.
