As the number of cars in China increases, the automotive wiring harness market becomes more and more hot. Why do you say that? For example, if we compare the functions of the microcomputer, sensor and actuator with the human body, we can say that the microcomputer is equivalent to the human brain, the sensor is equivalent to the sensory organ, the actuator is equivalent to the moving organ, and the harness is to open these organs Nerves and blood vessels. Electronic wiring harness.
Car wiring harness functionally speaking, there are two kinds of power lines that carry the power for driving the actuator and the input signal lines for transmitting the sensors. The power lines are thick wires that carry large currents, and the signal lines are thin wires that do not carry power, for example, for signal circuits Of the wire cross-sectional area of 0.3mm0.5mm in the motor, the implementation of components with a wire cross-sectional area of 0.85 1.25mm and the power supply circuit used wire cross-sectional area of 23mm2; and special circuits to use different specifications, the wire The larger the cross-sectional area, the greater the current capacity, so the choice of harnesses, in addition to considering the electrical performance, but also by the physical properties of the car when the constraints, so the choice of more.
