Abstract

The invention provides a breaker fixation bending plate and a processing method thereof, and a breaker. The breaker fixation bending plate comprises a flat plate, a first vertical plate and a second vertical plate, wherein the flat plate, the first vertical plate and the second vertical plate are sequentially connected and integrally formed, the first vertical plate and the second vertical plate are in relative parallel arrangement and are both vertical to the flat plate, the two vertical plates are provided with opening latch pin installation holes, the inner side of the first vertical plate is provided with two parallel ear plates vertical to the first vertical plate, and the two ear plates are provided with hand-operated closing and opening push rod installation holes. When a fixation bending plate is processed by use of the provided method, position precision and coaxiality of the two installation holes can be guaranteed, and the work performance of the breaker using the fixation bending plate can be guaranteed accordingly.

Description

technical field [0001] The invention relates to the field of circuit breakers, in particular to a fixed bent plate of a circuit breaker, a processing method thereof, and a circuit breaker. Background technique [0002] A circuit breaker refers to a switching device that can close, carry, and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. In practical applications, the circuit breaker includes a fixed bent plate and a closing and opening mechanism. The fixed bent plate is provided with a manual closing and opening push rod installation hole and an opening detent pin installation hole, and the two installation holes are coaxial holes. . From the viewpoint of ensuring the working performance of the circuit breaker, it is necessary to ensure the position accuracy and coaxiality of the installation holes. [0003] At present, the processing of the fixed bent plate is to divide the f...
