Causes of heating of power cord plug

In life, our electrical plugs often get hot. Why do they get hot? We all know that the plug gets hot due to overload or poor contact with the socket. Sometimes we find that changing the plug and reducing the load still can’t work.
In fact, there are many causes of fever, but the above two are common. Let’s talk about the possible reasons.
1. The quality of the socket is not good. The clamping force of copper strip in poor quality socket may not be enough, resulting in poor contact between socket and plug. As long as the appliance is used, the socket and plug will heat up. This happens because when buying sockets, they are greedy for cheap and buy “three noes” products. Therefore, when buying electric products, we should not be greedy for cheap, but buy regular products
Socket, because it is closely related to our safety. No negligence.
2. The plug is oxidized or too dirty. The plug will be oxidized or greasy after a long time, especially in the kitchen or places with poor environment. As a result, the contact resistance between the plug and the socket increases, and the load power is large, resulting in the plug heating. If it is not handled in time, it will form a vicious circle, which is easy to cause fire after a long time.
Solution: often observe and wipe the plug. Severe oxidation must be polished with sandpaper before use. Or replace the socket.
3. Rural families and old house residents in cities and towns are connected to a variety of high-power appliances at the same time due to the unreasonable socket layout. Since the multi-purpose socket and power connection line have rated capacity, a variety of household appliances, especially high-power appliances, are opened and used at the same time on the same multi-purpose socket, which is bound to cause too much current and overheat the multi-purpose socket and plug.
Solution: household appliances and high-power appliances (such as TV, refrigerator, microwave oven, induction cooker, computer, audio, etc.) with fixed position should be connected to the fixed socket separately, and the power line connected to the fixed socket of high-power appliances should also be led out directly from the household distribution box; For some frequently moving electrical appliances, multi-purpose sockets can be used, but they should be used with caution. Do not turn on multiple electrical appliances at the same time to ensure safe use.
