What are the quality requirements of the wire harness for the electronic wire connector? Electronic connectors should meet the specifications, add the contact surface of the wire as much as possible, and avoid the hook connector implementation method to connect through the terminal. First, the multiple strands should be tightened and the filament should not be exposed. On the terminal, the washer screw on the pad, and the cover should be tightened. The connection method of large cross-section wire and aluminum connection core wire is easy to use welding or crimping. When the crimping method can be used, conductive paste can be applied. The copper-aluminum wire transition joint is easy to use the copper-aluminum transition joint; it can also be connected with copper and aluminum. Put a thin layer of copper or tin on the copper wire nose, and then connect it with aluminum wire. This realization can reduce the contact resistance. The position of the electronic wire connector is staggered. The joints of each phase wire should be interlaced.
The outside of the adapter should be wrapped 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 heat preservation function. It cannot exist in the electrical structure. Fortunately, you must take preventive measures and pay attention to all the above steps to avoid fire accidents due to poor electrical connections. Oxidation of conductor junctions In the ecological environment of humid and corrosive air, an oxide layer is simply formed on the conductor, and copper oxide lines will appear on the copper. The conductivity of alumina is more likely to be formed on the aluminum wire. In the workshop, the wires of the wire harness were corroded by acid air for a long time, and the conductors formed an oxide layer in appearance, resulting in increased contact resistance. After the power is turned on, high temperatures will occur.
