Abstract
A plug has a power supply module, a leakage detection module, a timing module, an input terminal for external power supply and an output terminal for outputting voltage, a current loop is formed between the input terminal and the output terminal, the power module is connected to an external power source through the input terminal, the power module includes a rectifier unit Dand a power control unit, the input of the rectifier unit Dand the input terminal are electrically connected. The invention has the function of automatically disconnecting the line output when the line has leakage, protecting the plug and the externally connected electrical appliances, and at the same time, it can automatically perform self-checking at regular intervals to check whether the leakage protection function can be used normally, thereby improving the plug's reliability.
