Automotive wiring harness is an essential component of the electrical wiring system within a vehicle. It combines various wires, cables, and connectors to provide power supply, signal transmission, and control functions for the vehicle.
The classification of automotive wiring harness can be based on its functional responsibilities. For instance, there are engine electrical system wiring harnesses, body electrical system wiring harnesses, and cabin electrical system wiring harnesses. Each harness is responsible for different tasks such as engine control, lighting, dashboard, audio systems, and safety airbags.
Another classification criterion is based on the location of the wiring harness within the vehicle. Examples include engine compartment wiring harnesses, dashboard wiring harnesses, and door wiring harnesses. Wiring harnesses in different locations need to consider factors such as temperature, protection, and vibration to ensure reliability and safety.
The classification of automotive wiring harness can also be based on the number and types of wires included. A wiring harness can contain anywhere from a few to several hundred wires, which can vary in terms of specifications, colors, and purposes. Examples of wire types include low-voltage power lines, signal lines, sensor lines, and communication lines.
In addition, the type of connectors used in the automotive wiring harness can also be a classification criterion. Connectors play a crucial role in ensuring reliable connections between wires. Common connector types include plugs, sockets, and terminals.
Furthermore, the adaptability of the automotive wiring harness to different environmental conditions is another classification criterion. The interior of a vehicle is exposed to various environmental factors such as high temperatures, low temperatures, humidity, corrosion, and vibrations. Wiring harnesses need to possess appropriate protective features and durability to withstand the challenging automotive environment.
Lastly, the classification of automotive wiring harness can be based on the safety certifications and standards it complies with. Examples include the ISO 26262 safety standard in the automotive industry, UL certification, or specific requirements from automotive manufacturers.
It is important to note that the specific classification descriptions of automotive wiring harness may vary depending on the vehicle model, manufacturer, and specific requirements. When selecting and using automotive wiring harnesses, it is recommended to refer to relevant automotive manufacturer specifications and technical documentation to ensure the selection of harnesses that are suitable for the specific vehicle and application requirements.
