The connector of a general electronic product and the plug of an electrical appliance are called plugs. A plug and a socket for domestic AC power supply are composed of a male connector with bar or copper plate and a female connector with slot or concave hole for physically inserting it in them. It is not suitable for some electric appliances to be electrified for a long time.

For example, the electric blanket is frequently used in winter, and the electric blanket can make people feel warmer and more comfortable when sleeping. However, when people sleep at night, people usually do not turn off the electric blanket in the middle of the night, so that the electric blanket is in an on state all the night. Therefore, the electric energy resource is wasted, and because the heat generated by the electric blanket cannot be lost quickly, the electric blanket can be ensured to feel the heat all night by only being opened for a period of time, so that a plurality of users can select to open the electric blanket before sleeping and then close the electric blanket when sleeping, but the users forget to close the electric blanket, and the electric energy resource is wasted. Meanwhile, the electric blanket is opened all night to cause safety accidents, and accidents such as electric leakage, fire and the like are frequently caused by poor contact at the plug or the reason of the electric blanket, so that the electric blanket is very important to be closed at regular time.

If the mobile phone charger is composed of the plug and the data line, people often only directly take away the mobile phone after charging is completed, and the plug is still inserted into the socket, so that the charger is still in a power-on state, the aging degree of a charging circuit in the charger can be accelerated, the service life of the charger can be shortened, and even safety accidents can be caused. And the mobile phone is charged all night, and the mobile phone is charged continuously after being fully charged, so that the service life of the charger is reduced, and the service life of a mobile phone battery is influenced.

It can be seen from the above examples that it is not preferable for some electric appliances to be powered on for a long time, especially for charging type electric appliances, the aging speed of its internal charging circuit is accelerated when the charger is in an idle state, and the life of its internal battery is affected by the continuous charging after the electric appliance is fully charged, so there is a need for a plug capable of self-power-off at regular time.
