What are the quality requirements of wire harness for electronic connector? Electronic connectors should comply with the specifications, as far as possible increase the contact wire, and prevent the hook joint implementation method through the terminal connection, first of all should tighten more shares, should not be filament exposed, the wire must be bent into a ring shape, placed on a terminal, mat washer screw, the cover should be tightened, link method of large cross-section wire and aluminum wire welding or pressure welding method is easy to use. When the crimping method is available, conductive paste may be applied. Copper aluminum wire transition joint is easy to use copper aluminum transition joint; It can also be connected with copper and aluminum. Place a thin layer of copper or tin on the nose of the copper wire and connect it with aluminum wire. This implementation can reduce the contact resistance. The positions of the electrical wire connectors are staggered. The joints of each phase line should be staggered. The outer side of the connector should be covered with a large black rubber band 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 the steps above to prevent a fire accident due to poor electrical connection contact. Oxidation of conductor junction In the ecological environment of moist and corrosive air, oxide layer is easy to form on the conductor, copper oxide wire will appear. The conductivity of alumina is more likely to form on aluminum wires. In the workshop, the wiring harness is corroded by acidic air for a long time, and the conductor forms an oxide layer on the appearance, resulting in increased contact resistance. When the power is switched on, a high temperature will be generated.
