What Are The Quality Requirements Of Electronic Wire Joints For Wiring Harness?

What are the quality requirements of electronic wire joints for wiring harness? The electronic joint should meet the specifications, increase the contact surface of the wire as much as possible, and prevent the hook joint implementation method through the terminal connection, first should tighten the strands, should not be exposed, the wire must be bent into a ring shape, placed on the terminal post, washer screw on the pad, the cover should be tightened, connection method large section line and aluminum connecting core wire easy to use welding or crimping method. Conductive paste can be applied when the crimping method is available. Copper aluminum wire transition joint easy to use copper aluminum transition joint; It can also be connected with copper and aluminum. Place a thin layer of copper or tin over the nose of the copper wire and connect it with aluminum wire. This implementation reduces contact resistance. The electronic wire connectors are staggered. The joints of each phase line shall be staggered. The outside of the connector should be wrapped with a large black rubber belt with a cross-sectional area. The interior should be coated with yellow wax cloth or yellow wax cloth to improve the insulation function. It cannot exist in the electrical structure, fortunately, you must take precautions and pay attention to all of the above steps to prevent fire accidents due to poor contact of electrical connections. Oxidation of conductor connection In the ecological environment of moist and corrosive air, the conductor is easy to form oxide layer, copper will appear copper oxide wire. The conductivity of alumina is more likely to form on aluminium wires. In the workshop, the harness wire is corroded by acidic air for a long time, and the conductor forms an oxide layer on the appearance, resulting in increased contact resistance. After the power is switched on, high temperature will be generated.
