Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As illustrated, a kind of accident indicator of miniature circuit breaker, including housing 1, operation handle 2, contact supporter
3rd, tripping 4 and indication piece 5；The tripping 4 is hinged on the contact supporter 3, and the indication piece 5 passes through the housing 1
Interior central shaft 11 is hinged in the housing 1, and the housing 1 is provided with window window 12 corresponding with the indication piece 5, described
Indication piece 5 is provided with to be driven and the indicating fault position after being clockwise pivoted and by the contact supporter 3 by the tripping 4
Normal indicating positions after driving and rotating counterclockwise, operator can check whether that red-label can be seen by window window, i.e.,
Can directly judge breaker whether disjunction, without detecting and disassembling circuit, just can be rapidly performed by circuit maintenance.With structure letter
The characteristics of single, easy to use, stability is good and safe.
The U-shaped bar 21 for being used for linking each other, the two ends of U-shaped bar 21 difference are provided between the operation handle 2 and tripping 4
Rotate and be connected with the operation handle 2 and tripping 4, the tripping and operation handle are designed with what is coordinated with the U-shaped bar two ends
In axis hole, practical application, other articulated manners can be also used, it is to rotate to be connected with tripping and operation handle only to need U-shaped bar two ends
.
