The main function of shielding sleeve in automotive wiring harness

Shielding sleeves are used for wiring of various types of automobiles, airplanes, air conditioners and other household appliances. Automobile wiring harness refers to the contact terminal (connector) punched from copper material and the wire and cable are crimped, and then the outside is molded with an insulator or an external metal shell, etc., and the wiring harness is bundled to form a component that connects the circuit. In modern cars, there are many automotive wiring harnesses, and the electronic control system is closely related to the wiring harness.

The car wiring harness is the main body of the car circuit network, connecting the electrical and electronic components of the car and making them function. Without the wiring harness, there is no car circuit. At present, whether it is a high-end luxury car or an economical ordinary car, the wiring harness is basically the same in the form of wiring, which is composed of wires, connectors and wrapping tape. It not only ensures the transmission of electrical signals, but also ensures that the circuit is connected. Supply the specified current value to electronic and electrical components, prevent electromagnetic interference to surrounding circuits, and eliminate electrical short-circuits.

  In terms of functions, automotive wiring harnesses are divided into two types: power lines that carry the power of the actuators that drive the actuators and signal lines that transmit the input commands of the sensors. Power lines are thick wires that carry large currents, while signal lines are thin wires that do not carry power for optical fiber communication; for example, the cross-sectional area of wires for signal circuits is 0.3, 0.5 mm2. The selection of wires, in addition to considering the electrical performance, is also restricted by the physical performance of the vehicle, so the selection range is very wide.
