Background technique

The socket is also called a wiring board or a socket, which is a porous socket formed by putting multiple sockets together. Sockets are a necessity in daily life and are widely used in homes, offices and other areas to connect electrical equipment. Existing power strips generally include a main body with multiple jacks, a power cord, and a power cord plug that is electrically connected to an external power supply so that various wires inserted into the jacks are electrically connected to the external power supply , to facilitate the connection of external power supply and various electrical appliances.

However, in the existing sockets, the metal sheet is directly connected to the neutral wire and the live wire. Therefore, even if the plug is connected to the socket power supply, even if the plug does not fully enter the socket, or is only inserted into any jack, it is very easy to cause an electric shock. Moreover, because children have strong curiosity and weak safety awareness, they are likely to use fingers or metal objects to insert into the socket, thereby causing electric shock accidents. Therefore, the existing row and socket structure is unreasonable and has low safety.
