A connection terminal with a power-off switch

Abstract

The invention provides a wiring terminal with a power-off switch. The wiring terminal comprises a terminal base, a transverseT-shaped slot is formed on the terminal base, the T-shaped slot penetrates through a right end face of the terminal base, multiple groups of rectangular slot holes each two of which are opposite to each other are formed on an upper bottom surface and a lower bottom surface of the T-shaped slot, the rectangular slot holes penetrate through the upper bottom surface and the lower bottom surface of the T-shaped slot, a through hole penetrating through a front end face of the terminal base is formed on a front side wall of each rectangular slot hole, a fastening screw is inserted in the through hole, a side wall penetrating through a box-shaped connecting piece of the fastening screw is hinged with a clamping plate, the clamping plate is inserted in the connecting piece, and the connecting piece is inserted in each rectangular slot hole of the terminal base; a strip-shaped T-shaped moving block is inserted in the T-shaped slot of the terminal base, an annular elastic metal piece is inserted on the T-shaped moving block, the elastic metal piece is composed of two vertical parts and two arc-shaped parts, the arc-shaped parts are formed at upper and lower ends of the vertical parts, and the arc-shaped parts are propped on the connecting piece. The wiring terminal provided by the invention is simple in structure, is convenient to manufacture, can automatically turn off the power supply during connection and is relatively good in safety during the connection.

Description

Technical field: [0001] The invention relates to the technical field of electrical connectors, in particular to a connection terminal with a power-off switch. Background technique: [0002] The terminal block is an accessory product used to realize electrical connection. The existing terminal block is generally provided with a plurality of connection seats, which can be used for connecting multiple cables. The connection and fixation of the existing terminal blocks is generally bolt fastened connection. When connecting, the cable is plugged into the directly charged connector on the terminal block, which is less safe. Therefore, it is generally necessary to turn off the power to connect. It is more troublesome to turn off the power with one cable. Invention content: [0003] The purpose of the present invention is to provide a connection terminal with a power-off switch for the deficiencies of the prior art, which has a simple structure, is easy to manufacture, can automa...
