The present specification discloses a socket comprising an input terminal configured to be electrically connected to an AC power supply, an output terminal configured to output an alternating currentsignal of an alternating current power supply, a switching circuit electrically connected between the input terminal and the output terminal, a buck circuit electrically connected to the input terminal and configured to reduce an amplitude of the AC signal, a shaping circuit electrically connected to the buck circuit and configured to convert the AC signal of which the amplitude is reduced into ashaping signal, and a control circuit electrically connected to the shaping circuit and the switching circuit and configured to control the switching circuit based on the shaping signal such that theswitching circuit performs a switching operation only when the AC signal is at a zero potential. The specification discloses a door. The door comprises the socket. According to the socket and the doordisclosed by the specification, the sparking phenomenon of the contact of the relay when the relay is closed or released in an on-load state is avoided.
Description
technical field [0001] This application relates to the field of electrical appliances, in particular to sockets and doors. Background technique [0002] At present, smart sockets generally use relays to control power output. When the load is on, the contacts of the relay will spark when they are pulled in or released. In the case of a large load, it is very likely to cause the contacts to melt, which will cause the relay to stick, make the relay invalid, and affect the service life of the entire smart socket. [0003] Therefore, there is a need for an improved smart socket. Contents of the invention [0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by one or more embodiments of this specification is to prevent the switch device in the smart socket from sparking when it is engaged or released. [0005] In order to solve the above technical problems, one aspect of this specification provides a socket, which includes: ...
