Problems solved by technology

The copper sheet in the existing socket is connected to the terminal, and the copper sheet is charged during use. If a child's fingers or small metal parts touch the copper sheet, there is a danger of electric shock. Sparks are easily generated, especially when there is a short circuit inside the load, the contact part will cause a high-temperature arc, causing equipment damage and personal injury
In order to use safely, there is a kind of safety socket, which is provided with a safety protection door at the port of the jack. Only when the pins are inserted in the jack simultaneously, the safety protection door can be opened. Although it can prevent children from getting an electric shock, the reliability of use is not good. Moreover, sparks and arcs cannot be avoided

Abstract

The invention provides a safety socket, relating to the field of household appliances. An important improvement lies in that a copper sheet in the socket is connected with a wiring terminal via a press switch, a press part of the press switch is in contact with a plug inserted to a jack, and the press switch is a lever-type clutch mechanism or a direct-type clutch mechanism. When the socket is used, a power supply can be connected only when the plug is inserted in place to make the press switch closed, the copper sheet is not charged when the plug is not inserted, therefore, electric shock caused by a child finger or a small metal piece touching the copper sheet can be prevented, spark or arc generation at the jack also can be avoided, and an accident is prevented.

Description

technical field [0001] The invention relates to a household appliance socket, in particular to a safety socket for preventing electric shock. Background technique [0002] The socket is widely used to connect or disconnect the power supply of various household appliances. The socket is usually composed of an insulating base plate, a jack with copper sheets, and a terminal for connecting to the power supply. The copper sheet in the existing socket is connected to the terminal, and the copper sheet is charged during use. If a child's fingers or small metal parts touch the copper sheet, there is a danger of electric shock. Sparks are easily generated, especially when there is a short circuit inside the load, the contact part will cause a high-temperature arc, causing equipment damage and personal injury. In order to use safely, there is a kind of safety socket, which is provided with a safety protection door at the port of the jack. Only when the pins are inserted in the jack ...
