Abstract
The utility model relates to an interlocking-type miniature circuit breaker and mainly solves the technical problems that conventional miniature circuit breakers used in products, such as voltage stabilizers, on special occasions needing power switching are high in production cost, unreliable in performance, and easily failed in interlocking function. The circuit breaker comprises an A phase shell and a B phase shell. The A phase shell is provided with a first through hole, while the B phase shell is provided with a second through hole. A chute is arranged between the A phase shell and the B phase shell. A push rod is mounted in the chute and provided with a first clamping stage and a second clamping stage. A second lever is provided with a boss. The first clamping stage penetrates through the first through hole to be fitted with a first locking buckle, while the second clamping stage penetrates through the second through hole to be fitted with the boss of the lever. The second lever rotates to enable the boss and the second clamping stage to be clamped, thereby pushing the push rod to slide along the chute to cause the disconnection of the first locking buckle and a first tripping buckle. The circuit breaker employs the push rod, the lever, and the locking buckles cooperatively and uses the push rod to realize the A phase and B phase interlocking function. The circuit breaker is advantaged by being low in cost, reliable in performance, good in strength, good in interlocking function effect, long in service life, and not easy to deform.
