Mobile WebSiteIn modern automobiles, there are many automotive wiring harnesses, and electronic control systems have a close relationship with wiring harnesses. Someone once made an image metaphor: If you compare the functions of a microcomputer, sensors, and actuators with the human body, you can say that the microcomputer is equivalent to the human brain, the sensor is equivalent to a sensory organ, and the actuator is equivalent to a moving organ. Then the wiring harness is nerve and Blood vessels.
The automotive wiring harness is the network main body of the automobile circuit, connects the electrical electronic component of the car and makes it function, there is no car circuit without the wire harness. At present, the form of wiring harnesses is basically the same whether it is high-grade luxury cars or economical ordinary cars. It is composed of wires, connectors, and wrapping tapes. It is necessary to ensure the transmission of electrical signals as well as the connection circuits. The reliability of the supply of electrical current values to electrical and electronic components, to prevent electromagnetic interference on the surrounding circuit, and to eliminate electrical short circuit.
The automotive wiring harness is functionally divided into two types: power lines that carry power for driving actuators (actuators) and signal lines that transmit sensor input commands. The power line is a thick wire that carries a large current, and the signal line is a thin wire (optical fiber communication) that does not carry electricity; for example, the conductor cross-sectional area for a signal circuit is 0.3, 0.5 mm2.
With the increase of automobile functions and the widespread application of electronic control technologies, more and more electrical parts are being used, and more and more electrical wires will be used. The number of electrical circuits and power consumption on automobiles will increase significantly, and the wiring harness will become thicker and heavier. . This is a big problem that needs to be solved. How to make a large number of wire harnesses more effective and rationally arranged in a limited space of automobiles, so that the automotive wire harnesses can play a greater role has become a problem facing the automotive industry.
