Abstract

The invention provides a connecting piece, a locking mechanism with the connecting piece, a fixing mechanism with the connecting piece, an installation assembly with the connecting piece and a breakerwith the connecting piece. The connecting piece comprises a first support arm and a second support arm which are connected. A rotary connecting part is arranged between the first support arm and thesecond support arm. A first boss is formed on the first supporting arm, an elastic supporting arm integrally extends on the first supporting arm, the extending direction of the elastic supporting armdeviates from the first boss, a second boss is formed on the second supporting arm, and the direction of the second boss is the same as the extending direction of the elastic supporting arm. The invention provides a connecting piece. The locking mechanism can be simultaneously suitable for locking or unlocking the button. The fixing mechanism is used for fixing and unlocking the plug-in circuit breaker. Therefore, the structure is simplified to the greatest extent, the assembly difficulty is greatly reduced, the occupied space is small, more space can be reserved for arranging other components, the distribution among the components is more reasonable, and the miniature circuit breaker is suitable for miniature circuit breakers.

Description

technical field [0001] The invention relates to the field of circuit breakers; in particular, it relates to a connector, a locking mechanism with the connector, a fixing mechanism, a mounting assembly and a circuit breaker. Background technique [0002] Circuit breakers are divided according to installation methods: plug-in type, fixed type and drawer type. The use of plug-in type circuit breakers can effectively improve the safety of the electrical equipment industry. In order to meet the installation needs of various electrical equipment, the structure of the plug-in circuit breaker has also developed into various types. At present, in the layout of the existing traditional plug-in circuit breaker products in the installation position, generally press the operation button to break the circuit. The circuit breaker is closed, and the operating button of the circuit breaker springs back to reset after the operating force is removed, and the circuit breaker is disconnected whe...
