Abstract
The utility model discloses a moulded case circuit breaker comprising a base seat and a cover shell arranged on the base seat, wherein the cover shell is provided with installation holes, the cover shell is also provided with a clamping groove, a clamping opening is positioned on the clamping groove, and a key is arranged in the clamping groove. Through adoption of the above mode, the moulded case circuit breaker is advantageous in that switch-on and switch-off operation can be quickly and manually realized, the efficiency is improved, and the operation safety is improved.
Description
Technical field
The utility model relates to field of circuit breakers, particularly relates to a kind of breaker of plastic casing.
Background technology
Breaker of plastic casing is as a kind of general electronic corporation, owing to its compact conformation, price is low and stable and reliable for performance being used widely.Breaker of plastic casing runs into some special situations in use, when can not carrying out work normally, motor-operating mechanism just need carry out manual operation, and existing breaker of plastic casing self does not have hand-operated tools usually, can't carry out the on/off switch operation rapidly, operating efficiency and fail safe can not get ensureing like this.
The utility model content
The technical problem that the utility model mainly solves provides a kind of breaker of plastic casing, can manually carry out the operation of on/off switch fast, has improved efficient, has increased the fail safe of operation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of breaker of plastic casing is provided, comprises pedestal and the case that is arranged on the pedestal, case is provided with installing hole, have draw-in groove on the described case, draw-in groove is provided with bayonet socket, is provided with key in the described draw-in groove.
Preferably, the described notch that has on the key, the position of corresponding notch has breach on the described case.
The beneficial effects of the utility model are: the utility model can improve the efficient that needs the manual operation on/off switch, does not need to look in addition at the scene some other instrument to operate, thereby has increased the fail safe of operation.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model breaker of plastic casing;
Fig. 2 be shown in the plan structure schematic diagram of breaker of plastic casing;
Fig. 3 be shown in the right TV structure schematic diagram of breaker of plastic casing;
Fig. 4 be shown in the structural representation of key in the breaker of plastic casing;
The mark of each parts is as follows in the accompanying drawing: 1, pedestal; 2, case; 21, draw-in groove; 22, breach; 3, key; 31, notch.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection range of the present utility model is made more explicit defining.
See also Fig. 1 to Fig. 4, the utility model embodiment comprises:
A kind of breaker of plastic casing, comprise pedestal 1 and the case 2 that is arranged on the pedestal 1, case 2 is provided with installing hole, have draw-in groove 21 on the described case 2, draw-in groove 21 is provided with bayonet socket, be provided with key 3 in the described draw-in groove 21, have notch 31 on the described key 3, the position of corresponding notch 31 has breach 22 on the described case 2.When needs carry out the operation of manual on/off switch, only need key 3 is taken out from draw-in groove 21, the breach 22 on the case 2 and the notch 31 of key 3 can make key 3 take out more easily, carry out on/off switch then and operate, and have improved efficient, have increased the fail safe of operating simultaneously.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
