Problems solved by technology

At present, the terminal block connection components that realize the above functions need to be available adjacent to the potential terminal block, which is often difficult to achieve in actual work.
Especially in the reconstruction project, it is often required that the power supply of the live terminal block cannot be interrupted, and at the same time there is no empty terminal block available around it, which brings a lot of inconvenience to the construction personnel.

Abstract

The invention discloses a terminal block and a terminal block-assisted expansion device. The terminal block comprises a terminal block insulating shell, wherein at least two fixed cavities are formed in the terminal block insulating shell; a conductive crimping frame capable of moving up and down is arranged in each fixed cavity; a conductive strip extends into a hollow cavity of each crimping frame from the lateral wall of one end of the corresponding fixed cavity; a wire jack is arranged on the lateral wall of the other end of each fixed cavity; a wire extends into the hollow cavity of each crimping frame from the corresponding wire jack and is pressed and fixed by the inner surface of the bottom surface of the corresponding crimping frame and the conductive strip; all crimping frames on the same terminal block share the same conductive strip; and the terminal block insulating shell is provided with a terminal block-assisted expansion device connection cavity at the upper part of the corresponding conductive strip. The terminal block-assisted expansion device comprises a conductive connection assembly and an expansion position; the conductive connection assembly is connected to and fixed in the terminal block-assisted expansion device connection cavity; and a wire is pressed into the expansion position, so that equipotential connection or expansion of the terminal block can be achieved.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a terminal block and an auxiliary extension device for the terminal block. Background technique [0002] The application range of electrical equipment is very wide. As an important part of electrical equipment, terminal blocks play the role of electrically connecting its internal electrical components. In practical applications, it is often necessary to conductively connect the bus bars of two or more terminal blocks to each other along the arrangement direction, so as to realize the lateral distribution of one or more potentials along the arrangement direction. At present, the terminal block connection components that realize the above functions need to be available adjacent to the potential terminal block and adjacent to the free terminal block, which is often difficult to achieve in actual work. Especially in the reconstruction project, it is often required that the power...
