Plug-in type miniature circuit breaker housing installation structure

Abstract

The invention provides a plug-in type miniature circuit breaker housing installation structure, which comprises a housing body (1) of a hexagonal cuboid structure, and is characterized in that the upper portion of the left side surface of the housing body (1) is provided with a button (2), the left side surface is provided with a left wiring terminal 1 (3) and a left wiring terminal 2 (4) below the button (2), guide limiting grooves (101) are formed in the upper portion and/or bottom portion of the front side surface and/or rear side surface of the housing body (1), a right wiring groove 1 (5), an information line wiring groove (6) and a right wiring groove 2 (7) are formed in the right side surface of the housing body (1) from bottom to top in sequence, and buckles (8) are arranged on the upper side surface and/or lower side surface of the housing body (1) on one side of the button (2). The plug-in type miniature circuit breaker housing installation structure adopts a plug-in type customized interface, so that a loop in which a circuit breaker is arranged has the shortest current path in a whole low-voltage power transmission and distribution conductive system, and the installation and wiring spaces are saved, thus the materials are saved, and good economic benefit is generated.

Description

technical field [0001] The invention belongs to the technical field of circuit breaker equipment, and in particular relates to a plug-in small circuit breaker housing installation structure, which can meet the needs of DC current input and output from the inside and outside of the circuit breaker installation panel. Background technique [0002] Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Low-voltage circuit breaker, also known as automatic switch, is an electrical appliance that not only has the function of manual switch, but also can automatically protect against voltage loss, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, protect power lines and motors, etc., and can automatically cut off the circuit when they have severe overload, short circuit and undervoltage faults. Its function is equivalent to a fuse ...

AI Technical Summary

Problems solved by technology

[0004] The present invention is aimed at the layout of the installation position of the existing circuit breaker. One end of the output / input port of the connecting wire needs to be outside the panel of the installation cabinet, and the other end is inside the installation cabinet, and the overall direction is perpendicular to the panel. The technical defects of adding external connecting wires and copper bars, occupying a large space, and high switching costs
