Detection of Electronic Harness Failures Importance of Harness Assembly

To determine this, the electronic harness connectors and control switches at each end of the electrical and electronic wire equipment can be removed and the circuit can be detected as a short circuit by a meter or test light. Open circuit: wire open circuit failure, in addition to the obvious open phenomenon, rare failure mostly occurs between the wire and wire terminals. An electronic wiring harness some wires are cut, the outer insulation and wire terminals are intact, but the inner core wires and wire terminals have been cut.

Electrical Harnesses

To determine this, the heat-resistant conductor and the conductor terminals suspected of being open-circuited can be subjected to a tensile e-wire test. In the tensile test, if the conductor electronic wire insulation layer gradually thinning, the conductor can be considered open circuit. Poor line contact and faults are often found in connectors.

Automotive wiring harness assembly points of note connectors and sheath selection: general chassis wiring harness are used flame retardant and mechanical properties of the better corrugated sheath, while the cab wiring harness are used in cold, heat-resistant insulating plastic tape wrapping. According to the working environment of the automobile harness to assembly production. Segmented production: In order to subsequent assembly of automotive wiring harnesses and maintenance convenience, automotive wiring harness manufacturers generally segmented manufacturing, through the connector to connect multiple segments of the wiring harness together, in automotive applications, automotive wiring harnesses harnesses the fewer the better, you can avoid the connector is too much so as to produce a voltage drop, resulting in poor contact. At the same time, segmented production can be timely detection of poor contact, insulation and assembly errors and other defective products.
