Abstract
This utility model discloses an outdoor vacuum circuit breaker, relating to the field of vacuum circuit breakers. It includes a circuit breaker body, a housing, a protective structure, and a limiting structure. The housing is disposed outside the circuit breaker body; the protective structure is disposed on the circuit breaker body and is used to protect the circuit breaker body; the limiting structure is disposed on the protective structure and is used to limit the installation of the protective structure. This utility model involves moving a protective plate to the front of the housing. The protective plate moves downwards, causing the mounting block to slide into the buckle and fixing block, and driving the fixing post to slide into the mounting groove. This presses the top of one end of each limiting block downwards, causing the limiting block to rotate downwards around a fixed axis. The fixing post passes between the two limiting blocks. Simultaneously, the elasticity of a torsion spring causes the two limiting blocks and the protrusion to rotate back to the top of the fixing post, limiting the fixing post and facilitating the assembly of the protective plate.
