Plug board with function of automatic locking and shrinkage vertical-type plug board set therewith

Abstract

The invention relates to a plug board with a function of automatic locking and a shrinkage vertical-type plug board set therewith. The plug board comprises a circular jack on the plug board and a brush in the jack. The interior of the plug board is provided with a locking device for locking an electric plug. The locking device comprises an eccentric locking part which is disposed below the jack and used for locking the plug. The shape of the eccentric locking part is divided into three parts: a plugging part, a connecting part, and a locking part. The bigger the rotation angle of the eccentric locking part is, the bigger the clamping force is, thereby preventing the decrease of the elasticity of an electric connection piece and the decrease of a clamping force from causing the loosening of the plug after long-time repeated plugging and from causing poor contact. The shrinkage vertical-type plug board set provided by the invention comprises at least two plug boards with the function of automatic locking, and a pedestal for supporting the plug boards is disposed between the plug boards. A connecting rod is disposed between the pedestal and the plug boards and pulls the plug boards to move, thereby enabling the plug boards to be unfolded and folded, and effectively preventing wires from being messed up.

Description

technical field [0001] The invention relates to a socket, in particular to a plug-in board with an automatic locking function and a retractable vertical plug-in board set with the same. Background technique [0002] Socket is used for inserting various wiring, is convenient to connect with other circuits. Existing sockets generally rely on the self-elasticity of the electrical connecting piece to clamp the plug. In addition, when the socket is assembled, more sockets are needed, and the sockets will be covered by electric wires. Multiple electric wires are intertwined in disorder, which is inconvenient to use. For example, the Chinese invention patent whose publication number is CN1479418A and whose name is the electric shock-proof safety socket, in order to lock the plug, a spring is installed at the connecting part between the upper cover of the socket shell and the socket core. The elasticity decreases, and the clamping force decreases, causing the plug to loosen, causin...

Problems solved by technology

Existing sockets generally rely on the elastic force of the electrical connecting piece to clamp the plug tightly. In addition, when the socket is gathering wires, more sockets are needed, and the sockets will be covered by wires, and multiple wires are intertwined in disorder, which is inconvenient to use.

For example, the Chinese invention patent whose publication number is CN1479418A and whose name is the electric shock-proof safety socket, in order to lock the plug, a spring is installed at the connecting part between the upper cover of the socket shell and the socket core. The elasticity decreases, the clamping force decreases, causing the plug to loosen, causing problems such as poor contact, arcing, ignition, etc., and even burning the socket, which has certain defects.
