Abstract

The present invention relates to the field of low-voltage electrical appliances, and in particular to a circuit breaker. The circuit breaker comprises a circuit breaker shell and a locking mechanism.The locking mechanism comprises a locking piece and an elastic piece, one end of the locking piece is slidingly arranged in the circuit breaker shell and is connected with the circuit breaker shell through the elastic piece, the other end of the locking piece is provided with a locking bulge, and the locking bulge is protruded at the outer side of the circuit breaker shell through a first throughhole arranged in the side wall of the circuit breaker shell; when the circuit breaker is arranged to a circuit breaker assembling position, the shell of the circuit breaker assembling position extrudes the locking bulge to allow the whole locking piece to move in the direction of the internal portion of the circuit breaker shell, and after the circuit breaker assembling position is in place, the elastic piece allow the whole locking piece to move in the direction of the external portion of the circuit breaker shell, and the locking bulge is locked with the shell of the circuit breaker assembling position. The circuit breaker has a simple locking mechanism structure, is simple in locking operation and ensures the reliability of installation of the circuit breaker.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a circuit breaker. Background technique [0002] The use of circuit breakers can effectively improve the safety of electrical equipment. Plug-in miniature circuit breakers are an important part. In order to meet the installation needs of different electrical equipment, their structures have developed into various types. There are many plug-in miniature circuit breakers Equipped with a locking mechanism and an unlocking mechanism, which is an important condition to ensure reliable installation, convenient disassembly and safe electricity use of the circuit breaker. [0003] In the existing plug-in miniature circuit breaker, the locking mechanism and unlocking mechanism have complex structures, and if the plug-in miniature circuit breaker is in the closing state, if the locking mechanism fails, the miniature circuit breaker will come out of the circuit breaker assem...
