Automotive Wiring Harness is the "neural network" of the vehicle's electrical system, responsible for stably transmitting power and signals to various controllers, sensors and actuators.Wiring Harness seems simple, but in fact it is closely related to safety, reliability and assembly efficiency.
1. Typical composition of Automotive Wiring Harness
Wires (copper/tinned copper), connectors/terminals, sheathing and wrapping materials (tape, corrugated tube, network tube, heat shrink tube), fixing parts (tie, buckle, buckle), and necessary identification parts (label/sleeve/heat stamp).
2. According to common functions, it can be divided into
Power Wiring Harness (power supply circuit), signal Wiring Harness (CAN/LIN, etc.), sensor Wiring Harness, lighting Wiring Harness, engine compartment Wiring Harness, chassis Wiring Harness, instrument panel Wiring Harness, door panel Wiring Harness, and high-voltage Wiring Harness for new energy vehicles, etc.
3. Wiring Harness customized communication list (recommended)
1) Interface model and pin position definition; 2) Wire gauge/color/length and tolerance; 3) Shielding and grounding methods; 4) Temperature resistance, flame retardant and environmental requirements; 5) Appearance wrapping and sheathing requirements; 6) Test requirements (continuity/short circuit/insulation/voltage resistance, etc.); 7) Loading/installation direction and fixed points.
4. What does delivery consistency depend on?
In the prototype stage, the key points are solidified through drawings and process confirmation; in the mass production stage, through material batch management, first article confirmation, process inspection and test traceability, we ensure that each piece of Wiring Harness has "consistent practices and consistent performance."
Conclusion
If you need Wiring Harness customization or wiring optimization, it is recommended to start from the "installation space and direction" and conduct an overall assessment based on electrical specifications and assembly efficiency, which can often significantly reduce later problems.
