The reason why the power plug heats up during use

It is a common phenomenon that the power plug becomes hot during use. For example, the most common mobile phone charger. When your mobile phone is charging, you will find that the charger’s plug is very hot. What causes the plug to heat up during use? What people say verbally is to prevent the plug from getting hot and hot, which is actually the problem of the plug connection. Therefore, in the production process of the power cord plug, the connection must be done well. The plug must be tight and free of stacking. No twists and turns, no cracks, no high and low requirements on the surface, make the power plug as perfect as possible. The punching of different inserts must be operated through various molds of different sizes and shapes. It is necessary to match the number of seats, what kind of molds are used for what kind of inserts, and if other models of molds are used to punch the incompatible inserts, problems such as loosening and copper exposure will occur, so it must be produced accordingly. For power plugs such as South Africa, the terminals are relatively large, and thicker copper wires are needed to fix them, but if the wire diameter required by the customer is relatively small, how to deal with it? You can increase the length of the stripped copper, and then fold the copper wire in half to increase the thickness of the copper wire, so that the terminal can be firmly punched without loosening, and also the next manufacturing process. Another example is the British assembly plug. In the work, we must first pay attention to the copper-clad part of the power cord, and then proceed to the assembly steps. During the assembly process, pay attention to the length of the power cord inserted into the plug, as well as the tightness of the screws. If it is too loose, the upper and lower covers of the plug will move. All in all, find the cause of the plug heating, if it is not the cause of the current overload, it is the cause of the plug itself.
