Detailed Description

The following description of the embodiments of the present utility model will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It should be noted that all directional indicators (such as up, down, left, right, front, and rear … …) in the embodiments of the present utility model are merely used to explain the relative positional relationship, movement, etc. between the components in a particular posture (as shown in the drawings), and if the particular posture is changed, the directional indicator is changed accordingly.

As shown in the figure, the utility model discloses an indicator structure of an electric leakage breaker, which comprises a rotating shaft 3 which is in linkage arrangement with a breaker operating mechanism, wherein the breaker operating mechanism comprises a frame seat and a frame cover, the frame seat and the frame cover are matched to form an internal installation space, a jump button 14, a lock catch 13, a connecting rod 12, a reset plate 15 and other parts are arranged in the internal installation space, the rotating shaft and a handle 11 are directly in linkage arrangement through a U-shaped rod (omitted in the figure), the rotating shaft is used for fixing a moving contact (omitted in the figure) and driving the moving contact to open and close, the upper end of the rotating shaft extends upwards to form a clamping plate 31, a detachable indicator 2 is arranged on the clamping plate, a window 4 is arranged at the position of a shell corresponding to the indicator and used for displaying the state of the indicator, and meanwhile, the indicator can be replaced according to requirements.

The clamping plate 31 comprises a vertical plate 311 and a transverse plate 312 which are arranged at 90 degrees, the fixing reliability of the indicating piece can be realized by adopting the vertical arrangement at 90 degrees, the phenomenon that the indicating piece possibly shakes after being installed is avoided, accurate indication is affected, the highest surface of the vertical plate is higher than the highest surface of the transverse plate, and the limit of the indicating piece is realized by utilizing the cooperation of the vertical plate and the transverse plate, so that the indicating piece is more convenient to install.
