Safety socket

Technical Field

The invention relates to the technical field of sockets, in particular to a safe socket.

Background

The socket is also called as a power socket and a switch socket. A socket is a receptacle into which one or more circuit connections can be inserted, through which various connections can be inserted. Facilitating the connection with other circuits. The connection and disconnection between the circuit and the copper piece are realized to finally achieve the connection and disconnection of the part of the circuit.

In the process of using the socket in daily life, most sockets are embedded on a wall body and are low in position, so that children or adults with intelligence defects at low ages can inevitably use non-insulating rod-shaped objects to be inserted into the sockets by mistake, and electric shock accidents are caused.

To solve the above problems, we propose a safety socket.
