Abstract

The invention relates to a plug-type circuit breaker with few parts, good assembly operational performance, uneasily deformed plug-in terminal and high contact reliability. The plug-type circuit breaker is formed by connecting a plug adaptor and a circuit breaker main body bolts with a bolt connecting terminal. In the plug-type circuit breaker, a plug box is internally installed with: the plug-in terminal connected with any one of multiple bus poles by plugging in; and a socket mechanically connected with the circuit breaker main body. In the plug adaptor, a pair of convex parts is integrally formed on the plug-in terminal. A plug-in terminal mounting part composed of an opening is formed on the socket. At the same time, the plug-in terminal is electrically connected with the circuit breaker main body by a branch current conductor. The opening is actively embedded with the convex parts to support the plug-in terminal so that the plug-in terminal can rotate in a direction orthogonal to the bus poles.

Description

technical field

[0001] This invention relates to circuit breakers, and more particularly to plug-in type circuit breakers. Background technique

[0002] In conventional circuit breakers, claws made of elastic metal provided on the mounting plate of the circuit breaker are usually installed into locking holes provided under the rear end of the plug-in circuit breaker by utilizing its elasticity. However, since the installation to the circuit breaker mounting plate is performed simultaneously with inserting the plug-in terminals into the bus bar, it is necessary to press the rear end side of the plug-in circuit breaker from above the circuit breaker mounting plate so that the plug-in terminals Insert it obliquely upward to fit with the bus bar. Therefore, there is a possibility that the insertion terminal is deformed due to an excessive load, resulting in poor contact.

[0003] On the other hand, in order to prevent deformation of the insertion terminal due to height positio...
