The outside of the Micro USB cable connector should be wrapped with a large cross-sectional area of black rubber tape. The interior should be coated with yellow wax cloth or yellow wax cloth to improve thermal insulation. It can't exist in the electrical structure, luckily you have to take precautions and pay attention to all the above steps to avoid a fire accident due to poor electrical connections. Oxidation at the junction of conductors In the ecological environment of humid and corrosive air, the oxide layer is simply formed on the conductor, and the oxidized copper wire will appear on the copper. The conductivity of aluminum oxide is more likely to be built into the aluminum wire. In the workshop, the Wire Harness wire is corroded by acid air for a long time, and the conductor forms an oxide layer on the appearance, which leads to an increase in contact resistance. When the power is turned on, high temperature occurs.
