Power socket principle: The power socket relies on electric touch to transmit electric energy, and the transmission of electric energy will inevitably lead to a rise in the temperature of the plug and socket combination.


Provided that the temperature increase under full load complies with the upper value of the technical parameter rules, the plug and socket combination works stably when transmitting electrical energy.



For example, the general air conditioner indoor unit has an emergency switch, which is to check the quality of the air conditioner remote control. If the emergency switch can turn on the power, you should choose to replace the remote control. The power socket is cut off or the power cord is disconnected.


Of course, not all electrical equipment uses DC power. Alternating current is used in many appliances, household appliances, notably lamps, washing machines and refrigerators, and is delivered directly from the grid through electrical outlets.
