Design method of automobile wiring harness system

4. Design verification

According to its mechanical performance, electrical performance, and environmental performance, the wire harness connector needs to undergo terminal bonding force, terminal pull-out force, oscillating current, insulation strength, thermal aging resistance, high temperature resistance, salt spray resistance, temperature/humidity cycle and other related tests. The conductors need to undergo inspections and tests related to insulation stripping performance, insulation wear resistance, and hot pressing. Before mass production, the harness assembly must also complete relevant tests, including vibration resistance, salt spray resistance, voltage drop, industrial solvent resistance, temperature and humidity cycle change resistance, and electrical performance testing. Due to customer needs, relevant tests in various countries and regions Experimental requirements will vary depending on the project and compliance standards.

Conclusion

The development of intelligence and lightweight automobiles has brought unprecedented challenges to automobile wiring harnesses. From electrical schematics to two-dimensional wiring harness diagrams, from design concepts to wiring harness design completion, all must be well-founded, and the selection and matching of wiring harness-related components must be well-founded. It is necessary to strictly calculate and check, and design the wiring harness system well, so that wiring harness failure will no longer be the culprit of automobile failures.
