The main function of shielding sleeve in automobile wiring harness

Shielding sleeves are used for wiring of various kinds of household appliances such as automobiles, airplanes, and air conditioners. Automobile wiring harness refers to a component that is crimped with wire and cable with contact terminals (connectors) punched from copper, and then plastic-pressed insulators or metal shells are added to the outside to form a connected circuit component that is bundled with wire harnesses. In modern cars, there are a lot of car wiring harnesses, and the electronic control system is closely related to the wiring harness.

Automobile wiring harness is the main body of the automobile circuit network, which connects the electrical and electronic components of the automobile and makes it function. Without the wiring harness, there is no automobile circuit. At present, whether it is a high-end luxury car or an economical ordinary car, the form of the wiring harness is basically the same. It is composed of wires, connectors and wrapping tape. It must ensure the transmission of electrical signals and the connection of the circuit. Reliability, supply the specified current value to electronic and electrical components, prevent electromagnetic interference to surrounding circuits, and eliminate electrical short circuits.

The automobile wiring harness is divided into two types from the functional point of view. There are two types of power lines that carry power to drive the actuators and the signal lines that transmit sensor input commands. Power lines are thick wires that carry large currents, while signal lines are thin wires that do not carry power. Optical fiber communication; for example, the cross-sectional area of wire for signal circuits is 0.3 and 0.5 mm2. In addition to considering the electrical performance, the selection of the wire is also restricted by the physical performance of the vehicle, so it has a wide range of options.
