The requirements for materials of automobile wiring harness are also very strict:
Including its electrical performance, material emission, temperature resistance and so on, the requirements are higher than those of general harnesses, especially those related to safety.
1. The ambient temperature around the engine is high, and there are many corrosive gases and liquids. Therefore, the wires of the engine harness must be high-temperature, oil, vibration and friction resistant.
2. The wires on the automatic transmission are those with hydraulic oil resistance, high temperature resistance and good temperature stability.
3. The wire of the harness on the luggage compartment cover should maintain its elasticity at low temperature, so the cold elastic wire should be selected to ensure its normal operation.
4. Shielded wires shall be used for weak signal sensors.
5. The ABS harness assembly uses stranded wires that are resistant to 150-200 ℃ high temperature, hard and wear-resistant with external protective insulation, but with more than 133 cores.

6. Power lines, such as starter alternator output line and battery line, are special wires that can withstand high current, with good heat dissipation performance of insulation and low voltage.

The standard of the harness is mainly calculated by calculating its crimping rate. The calculation of the crimping rate requires special instruments. The standard detector of the harness section developed by Suzhou Oka optical instrument factory is the most effective detector specially used to detect whether the crimping of the harness is qualified. Mainly through cutting, grinding and polishing, corrosion, observation, measurement and calculation.
