Causes and treatments of electronic wire harness failures

Check the shielding layer braided network: whether the number of braided enough, copper braided network, check the weldability, tinned copper wire scraping to see if the inside is copper wire, aluminum-magnesium alloy wire hardness is significantly greater than the copper wire; braided network is sparse, uneven distribution, and the insulating layer is not tightly wrapped, etc. is poor cable. Electronic wire harness appearance lubricated round, uniform color. Commodities in line with the specification requirements of the wire and cable company, in order to product quality, to ensure that the goods meet the specification requirements, in the purchase of raw materials, production equipment, production processes and other aspects of strict control. Therefore, the appearance of the production of electronic wire harnesses to meet the specification requirements: lubricated round, uniform color. And the appearance of counterfeit and defective goods rough and lusterless. Rubber insulated flexible cable, the appearance of rounded, sheath, insulation, conductor tight and not easy to peel. And the appearance of counterfeit defective goods rough, oval degree, sheath insulation strength is low, with the hand can be torn off. Electronic wire harness in the external extrusion and impact, thus causing the wire harness inside the wire insulation layer is damaged, resulting in a short circuit between the wires, so that some electrical equipment out of control, the fuse was blown. If the wires are in poor contact, then most of the faults occur inside the plug, when the fault occurs, it will make the electrical equipment not work properly. In the judgment, turn on the power of the electrical equipment, pull or touch the electrical equipment related to the plug, when touching a certain plug, the electrical equipment can suddenly work, and suddenly can not work, it means that the plug has a fault. Electronic wiring harness in the use of the process of failure will occur mainly in the electronic wiring harness is ignited, burned, because the electronic wiring harness is generally no insurance device. When the electronic wiring harness is connected incorrectly inside the device, it is easy to cause a short circuit and other undesirable phenomena, thus triggering the damage of the electronic wire.
