Types and inspection methods of electronic wiring harnesses

Jan 17,2024

Electronic wiring harness is a bundle of wires used to connect electronic devices, consisting of wires, insulation materials, sheaths, etc. Wires are the core part of electronic harnesses, responsible for transmitting current or signals. Insulation materials are used to protect wires and prevent current or signal leakage. The sheath is used to protect electronic wiring harnesses from external environmental influences.
According to the structure and function of the wires, electronic harnesses can be divided into the following types:
Ordinary wire: Ordinary wire is made of single or multiple copper wire cores, wrapped with insulation material. Ordinary wires have good conductivity and mechanical strength, making them suitable for transmitting low current or low voltage signals.
Shielded wire: Shielded wire consists of a wire and a shielding layer. The shielding layer can prevent electromagnetic interference and improve the stability of signal transmission. Shielded wires are suitable for transmitting high-frequency signals or signals that are susceptible to electromagnetic interference.
Coaxial cable: A coaxial cable consists of a wire and a shielding layer, with an air or dielectric layer between the shielding layer and the wire. Coaxial cables have good shielding effects and are suitable for transmitting high-frequency signals or situations with high requirements for signal transmission quality.
Multicore cable: A multi-core cable is composed of multiple wires, each responsible for transmitting different signals. Multi core cables are suitable for situations where multiple signals need to be transmitted.
Flat cable: A flat cable is composed of multiple wires arranged in a flat shape. Flat cables have good flexibility and are easy to route, making them suitable for situations with limited space or frequent bending.
In practical applications, electronic wiring harnesses need to be regularly inspected to ensure their normal operation. The commonly used methods for checking electronic wiring harnesses include:
Visual inspection: Visual inspection is the basic method for inspecting electronic wiring harnesses, mainly checking whether the wires are broken, whether the insulation is damaged, and whether the connectors are secure.
Resistance testing: Resistance testing is an important method for checking whether wires are open or short circuited. Resistance testing can be performed using a multimeter or resistance tester.
Voltage testing: Voltage testing is an important method to check for leakage or grounding faults in electronic wiring harnesses. Voltage testing can be performed using a multimeter or voltmeter.
Insulation test: Insulation test is an important method to check whether the insulation performance of electronic wiring harnesses is good. Insulation testing can be conducted using an insulation resistance tester.
The inspection methods for electronic harnesses vary depending on the specific situation and application environment of the electronic harness. When conducting electronic harness inspections, the following principles should be followed:
Regular inspection: Electronic harnesses should be inspected regularly to ensure their normal operation. The inspection cycle should be determined based on the usage environment and conditions of the electronic harness.
Comprehensive inspection: The electronic harness inspection should be conducted comprehensively, including various parts such as wires, insulation materials, and sheaths.
Key inspection: Electronic wiring harness inspection should focus on areas that are prone to damage or malfunction.
Through regular inspections, faults in electronic wiring harnesses can be detected and eliminated in a timely manner, ensuring their normal operation.

1. Wire quality issues Low voltage resistance testing may be affected by wire quality. If there are problems such as poor welding, breakage, or substandard material quality in the manufacturing process of wires, it can lead to an increase in low-voltage resistance. At this point, visual inspection and testing of the wires are required to confirm if there are any issues. If there are any issues, the wires need to be remanufactured or replaced.
