What's a complete vehicle wiring harness? What's a complete vehicle wiring harness for?

In order to make the entire vehicle lines regular, easy to install and protect the insulation of wires, in addition to high-voltage lines, battery cables and starter cables, the entire vehicle lines on the car generally use insulating materials such as cotton yarn or thin polyvinyl chloride. Plastic tape is wrapped and wrapped into a bundle, which is called the whole vehicle wiring harness. The function of the vehicle wiring harness is to connect the electrical and electronic components of the car. What is the specific vehicle wiring harness and what is the vehicle wiring harness used for? Let's take a closer look in the article!

1. What is the vehicle wiring harness? The vehicle wiring harness is the main body of the network of the automobile circuit. Without the wiring harness, there would be no automobile circuit. A wire harness refers to a component in which a contact terminal (connector) punched from copper is crimped with a wire and cable, and then a compressive insulator or a metal shell is added to the outside, and the wire harness is bundled to form a connection circuit. 2. What is the vehicle wiring harness used for? Someone made an image metaphor. If the functions of microcomputers, sensors, and actuators are compared to the human body, then microcomputers can be said to be equivalent to the human brain, and sensors are equivalent to sensory organs. The actuator is equivalent to a kinematic mechanism. Then the bundles are nerves and blood vessels. The function of the vehicle wiring harness is to connect the electrical and electronic components of the car. At present, whether it is a luxury car or an economical ordinary car, the form of wiring harness is basically the same, consisting of wires, plug-ins and packing belts. The reliability of electrical signals and connecting circuits must be guaranteed to provide specified current values for electronic and electrical components. Prevent electromagnetic interference to surrounding circuits and eliminate electrical short circuits. The vehicle wiring harness is functionally separate, with two power lines carrying the power to drive the actuators (actuators), while the signal lines carry the sensor input commands. The power supply line is a thick line that carries a large current, and the signal line is a thin line that does not carry electric power (optical fiber communication). For example, wires used in signal loops have cross-sectional areas of 0.3 and 0.5 square millimeters, respectively.
