Automotive wiring harness refers to a component made of copper material that is punched into contact terminals (connectors) and crimped with wires and cables. It is then wrapped with plastic insulation or an external metal shell to form a connected circuit.
The automotive wiring harness is mainly composed of cables, wrapping materials, and connectors (terminals). Cables are the highest proportion of automotive wiring harnesses, with a weight composition of 75% -80%; The wrapping material provides protection for the vehicle wiring harness. Common wrapping materials include corrugated pipes, cloth tape, velvet tape, PVC sleeves, sponge strips, etc; A connector can be likened to a plug and socket in daily life, consisting of a housing, a fixing bracket, a seal, and terminals.
The function and appearance of each type of wiring harness vary depending on the location of the car,
1.Automobile Navigation Harness is responsible for connecting the navigation host (usually including core components such as display screens, processors, etc.) with the vehicle's power system, audio system, and other related control systems. It may include power lines, ground lines, audio signal lines, control signal lines, etc.
2.Automotive Modification Harness is a customized or modified wiring harness component based on the original automotive wiring harness. The modification of this type of wiring harness is to meet specific functional requirements, improve performance, adapt to new electronic devices, or undergo exterior modifications.
3.Automotive Button Modification Wiring Harness is a wiring harness component designed to modify the electrical connections of internal buttons in automobiles, such as multifunction steering wheel buttons, audio control buttons, air conditioning control buttons, etc. This type of modification is usually done to enhance the driving experience, add functionality, or adapt to new equipment.
4.The Automobile Headlight Wiring Harness is primarily responsible for transmitting power, control signals, and possible sensor signals to the headlights to ensure their proper functioning.
5.The Car Navigation Wiring Harness is responsible for transmitting the position and speed information of the GPS receiver to the control unit of the navigation system, achieving functions such as map display and route planning.
6.The main function of Car Video Harness is to transmit the video signal of the in car video equipment to the vehicle's display screen, achieving image display and viewing.
As the "neural network" of the automotive electrical system, wiring harnesses connect various electrical components and devices to achieve information sharing and collaborative work. This helps to improve the overall performance and stability of the vehicle's electrical system.
With the continuous development of automotive technology, in car devices are also constantly upgrading. The design of the wiring harness takes into account the upgrade requirements of the equipment, making it easy to replace or expand the wiring harness during equipment upgrades to meet new equipment needs.
