Information

The wire harness provides an overall set of service equipment for a certain load source group, such as trunk lines, switching devices, control systems, etc. So do you know what it is about its inspection and judgment knowledge? Let’s follow the 2mm pitch SMT pin header editor for a brief look!
1. Detection and Judgment of Burnout Failure of Electric Wire Harness
In the circuit of the power system, wherever the electric wire harness is grounded, the electric wire harness burns where it is burned out. The junction between the burned out and intact parts can be regarded as the grounding of the wires; if the electric wire harness is burned out to the wiring of an electrical device When it is located, it indicates that the electrical equipment is faulty.
2. Detection and judgment of short circuit, open circuit, and poor contact between lines
1. The electric wire harness is squeezed or impacted from the outside, causing damage to the insulation layer of the wires in the electric wire harness, resulting in a short circuit between the wires. When judging, you can disassemble the electric wire harness connectors at both ends of the electrical equipment and the control switch, and use an electric meter or test light to detect the short circuit of the circuit.
2. Wire break faults, except for obvious breaks, common faults mostly occur between the wire and the wire terminal. After some wires are disconnected, the outer insulation layer and the wire terminals are intact, but the inner core wire of the wire and the wire terminals are disconnected. When judging, you can do a tensile test on the conductive wire and the wire terminal that is suspected to be disconnected. During the tensile test, if the wire insulation layer becomes thinner, it can be confirmed that the wire is disconnected.
3. The line is in poor contact, and the fault mostly occurs in the connector. When a fault occurs, it will cause the electrical equipment to fail to work normally. When judging, turn on the power of the electrical equipment, touch or pull the relevant connector of the electrical equipment, when touching a certain connector, the electrical equipment works suddenly and abnormally, indicating that the connector malfunction.
The above is the 2mm pitch SMT pin header editor introducing the inspection and judgment knowledge of the wiring harness, you can learn more.
