Abstract
The utility model relates to a circuit breaker, in particular to a plastic shell circuit breaker. The circuit breaker comprises a base, an upper cover and a panel; the base is provided with a contactsystem; the upper cover is provided with a notch; the panel is arranged on the upper cover and covers the notch; the circuit breaker is characterized in that one end of the panel is hinged with the upper cover; and the other end of the panel is connected with the upper cover by a screw. In the utility model, as the panel is hinged with the upper cover, when the fitting needs to be installed, the screw is loosened and the panel is turned over so as to carry out operation; the panel and the upper cover are always connected together in the mode; therefore, the panel is not lost; furthermore, as the hinged shaft plays a positioning function, the panel is more convenient during the installation process.
Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of breaker of plastic casing.
Background technology
In breaker of plastic casing, for the ease of function accessories such as under-voltage, shunt opening, auxiliary, warning being carried out Installation and Debugging within it, offer a face shield last covering usually, when needs during to the equipped function accessories in inside, this face shield is pulled down, thus installation accessories easily just.And in these current breaker of plastic casing, but its face shield is that complete separated type anti-bending is connected with loam cake, and promptly face shield only is connected with loam cake by screw, and after unclamping screw, this face shield will separate with loam cake fully, and this just exists not enough: 1. face shield is lost easily; 2. panel and loam cake need be reorientated trip bolt again when each the installation, and operation is trouble comparatively.
The utility model content
The purpose of this utility model is to solve the deficiency of existing breaker of plastic casing, thereby and provide a kind of face shield can with loam cake not separate fully make the assembling convenient, reliable breaker of plastic casing.
The purpose of this utility model is achieved by the following technical solution: a kind of breaker of plastic casing, include base, loam cake and panel, contact system is housed on base, be provided with recess last covering, described panel is installed in and covers and cover recess, it is characterized in that: described panel one end and loam cake are hinged, and the panel other end is connected with loam cake by screw.
Further, the protruding relatively length in the both sides of the recess of described loam cake has coaxial cylinder boss to constitute panel and the hinged jointed shaft of loam cake, and the sidewall of the hinged seat of described panel is provided with the breach that communicates with hinge hole.
Further again, described breach for by hinge hole to the outside of panel hinged seat sidewall gradually increased cross-section be flaring breach.
The beneficial effects of the utility model are: because panel and loam cake are hinged, therefore when needs carry out installation accessories, as long as unclamping screw just can open panel and operate, its panel of this mode and loam cake are to connect together all the time, therefore the situation that panel is lost can not appear, and because hinged jointed shaft also plays positioning action simultaneously, so panel is convenient when mounted.

Embodiment
Now in conjunction with the accompanying drawings execution mode of the present utility model is further described:
As Fig. 1-shown in Figure 4, the embodiment of a kind of breaker of plastic casing of the utility model, include base, loam cake 1 and panel 2, electrical function elements such as contact system are housed (because the utility model does not relate to the improvement of base and interior electrical function element thereof on base, therefore do not look out base and electrical function element among the figure), on loam cake 1, be provided with recess 11, can be by this recess 11 under-voltage, shunt opening, auxiliary, function accessories such as warning are installed in this position and realize and the cooperating of contact system, described panel 2 one ends and loam cake 1 are hinged, thereby panel 2 other ends are connected with loam cake 1 by screw 4 and cover recess 11, be provided with bar shaped groove 23 on panel 2, circuit breaker handle (do not relate among this patent figure and not looking out) passes these groove 23 1 ends and exposes outside.When needs carry out installation accessories, as long as unclamping screw 4 just can open panel 2 and operate, its panel 2 of this mode is to connect together all the time with loam cake 1, therefore the situation that panel 1 is lost can not appear, and because hinged jointed shaft also plays positioning action simultaneously, so panel is convenient when mounted.
In the present embodiment, the protruding relatively length in the both sides of the recess 11 of described loam cake 1 has coaxial cylinder boss 111 to constitute the hinged jointed shaft of panels 2 and loam cake 1, and the sidewall of the hinged seat of described panel 2 is provided with the breach 22 that communicates with hinge hole 21.Jointed shaft 111 is wholely set promptly and can effectively reduces cost with loam cake 1, also make simultaneously easy for installation, only breach 22 need be exerted oneself once can easily panel 2 being connected on the loam cake 1 by jointed shaft 111 is snapped in the hinge hole 21 facing to jointed shaft 111, certainly for panel 2 more helps being installed on the loam cake 1, described breach 22 be made as by hinge hole 21 to the outside of panel hinged seat sidewall gradually increased cross-section be flaring breach.
Need to prove: above embodiment described in detail in conjunction with the accompanying drawings only is a preferred implementation of the present utility model; and be not qualification to protection range of the present utility model, any improvement of being done based on invention spirit of the present utility model is all naturally in the utility model protection range.
