what are automotive wiring harnesses?
Automotive Wiring Harnesses refers to the complete set of wiring systems used to transmit electrical energy and signals in the interior of an automobile. It consists of wires, connectors, terminals, sheaths, bellows, tapes and other components, and is used to connect the various electronic and electrical modules of the car (such as engine, lights, instrumentation, air conditioning, sensors, etc.) to realize the electrical function of the whole car. Automotive wire harnesses are mainly composed of the following parts:
- Wires
- Connectors
- Terminals
- Sleeves
- Branches
why use automotive wiring harnesses?
Automotive wiring harness is an indispensable core connecting component in the electrical system of the whole vehicle. It realizes stable power supply and data transmission for engine, instrument, lighting, air conditioning, sensors, entertainment system and other modules by integrating power and signal wires in a unified structure. Its standardized design not only improves the assembly efficiency of the entire vehicle, but also significantly reduces the failure rate and maintenance costs.
With the development of electrification and intelligentization of automobiles, wiring harness has been upgraded from a simple wire harness to a complex information interaction system. Modern automotive wiring harnesses support CAN, LIN, Ethernet and other communication protocols, with good anti-interference and environmental adaptability, and are the key infrastructure for realizing the functions of intelligent cockpit, ADAS, high-voltage power system and so on.
