In modern cars, the electronic control system is closely related to the wiring harness. Someone once made an image analogy: the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organ, the executive element is equivalent to the exercise tube, then the wire harness is the nerve and blood vessel.
The automobile wiring harness is divided into two types: the power line that carries the power of the driving actuator (actuator) and the signal line that transmits the input command of the sensor. The power line is a thick wire carrying a large current, and the signal line is a thin wire carrying no power (optical fiber communication).
The cross-sectional area of the wires for motors and actuators is 0.85 and 1.25 mm2, while the cross-sectional area of the wires for power supply circuits is 2, 3 and 5mm2; However, special circuits (starters, alternators, engine grounding wires, etc.) have different specifications of 8, 10, 15 and 20mm2. The choice of wire, in addition to considering the electrical performance, but also by the physical performance of the vehicle. For example, the frequently opened/closed doors on a taxi and the wires that span between the body of the car should be composed of wires with good flexural properties. In recent years, electromagnetic shielding lines used in weak signal circuits are also increasing.
With the increase of automobile functions and the widespread application of electronic control technology, the number of circuits and power consumption on automobiles have increased significantly, and the wiring harness has become thicker and heavier. How to make a large number of wiring harnesses more effective and reasonable in the limited automobile space Arrangement, so that the automobile wiring harness can play a greater function, has become a problem facing the automobile manufacturing industry.

Rectangular connector operating environment conditions Rectangular connector ambient temperature: refers to the product in the specified ambient temperature should be used. Even if the outside temperature is not high, if the rectangular connector product works in the chassis, the heat dissipation condition is poor, and other components heat up, the ambient temperature of the product will be much higher than the outside ambient temperature. Use in excess of the specified ambient temperature can also cause damage to the metal coating or insulation. Moisture or water: Moisture or water will form a water film on the surface of the insulator, which will reduce the insulation performance and even cause misleading communication between adjacent contact parts. In general, connectors that are used for long periods of time in high humidity or in the presence of water should be sealed.

Wire harness processing The main process of wire harness production
Acceptance of incoming materials: use ROHS instruments for environmental protection testing to test whether all incoming materials required for wiring harnesses meet ROHS standards. Equipment required: OHS tester equipment. Process requirements: incoming materials are not allowed to contain harmful substances such as lead (Pb), mercury (Hg), cadmium (Cd), brominated biphenyl (PBB) and polybrominated diphenyl ethers (PBDE).
