Technical field

The utility model relates to the technical field of sockets, in particular to a liner assembly and a smart socket device.

Background technique

Socket, also known as power socket or switch socket. It refers to a socket with one or more circuit wires that can be inserted through which various wires can be inserted. In this way, it is easy to connect with other circuits, and through the connection and disconnection between the line and the copper parts, the connection and disconnection of this part of the circuit is finally achieved.

At present, the protective door of the porous socket structure on the market is usually designed as a separate component, which is complicated to install on the outer shell, which also increases the cost. Multiple copper sheets of the same group are integrally installed on the inner shell of the inner shell of the component. The internal cavity and the inner liner component are composed of multi-layer components, which require assembly of multi-layer components, which is time-consuming and labor-intensive and has low production efficiency.
