Automotive wiring harnesses are usually composed of wires, insulating sleeves, Connectors, protective sleeves and fixing clips. The wire is the main part of the current transmission, usually made of copper wire, which has good electrical conductivity. Insulating sleeving wraps around wires to insulate and protect them from short circuits and electrical failures. Connectors are used to connect wiring harnesses and electrical equipment in vehicles, providing a reliable electrical connection. Protective sleeves are used to cover and protect the entire Wiring Harness from damage and interference from the external environment. The retaining clip is used to secure the position of the wiring harness in the vehicle, preventing loosening and vibration.
Automotive wiring harnesses play an important role in automobiles. They connect and provide power and signal transmission for various systems, such as engine systems, body electrical systems, cockpit electronic systems, instrument panels, lighting systems, etc. They enable the various electrical devices in the vehicle to work properly and provide stable and reliable power supply and information transmission. Automotive wiring harnesses can generally be divided into the following three types according to their functions and uses: Power wiring harness: The power wiring harness is mainly used to transmit power signals and power supply in vehicles. It connects the vehicle's battery, generator, starter and various electrical equipment to provide them with the power they need. Power harnesses usually consist of larger diameter wires to withstand higher current loads. They are often used to transmit high power currents, such as engine control systems, lighting systems, heating systems, etc. Signal harness: The signal harness is used to transmit signals and data in the vehicle. It connects various sensors, control modules, instrument panels, audio systems, etc., and transmits various sensor signals, control signals, audio signals and communication data. Signal harnesses typically consist of smaller diameter wires for carrying low current and high frequency signals. They are commonly used to transmit vehicle control signals, dashboard displays, audio and video signals, etc.
Hybrid Harness: A hybrid harness combines the functions of a power harness and a signal harness. It simultaneously transmits power signals and signal data to meet the needs of various electrical equipment in vehicles. Hybrid wiring harnesses typically include different gauges and types of wires for carrying high power currents and low power signals. They are commonly used in systems in vehicles that require simultaneous transmission of power and signals, such as hybrid systems, electric vehicles, etc. Since automotive wiring harnesses need to adapt to the complex working environment of the car, they usually have high heat resistance, oil resistance, moisture resistance and vibration resistance. In addition, automotive wiring harnesses also need to comply with relevant automotive industry standards and safety requirements to ensure their quality and reliability.
