Description
Technical field
The utility model relates to a kind of base pressure electrical equipment, especially a kind of miniature circuit breaker.
Background technology
Miniature circuit breaker structure comprises the housing of mini-type circuit breaker be made up of base, upper cover, end of incoming cables binding post mounting groove and leading-out terminal binding post mounting groove is respectively equipped with at base two ends, in end of incoming cables binding post mounting groove and leading-out terminal binding post mounting groove, be separately installed with end of incoming cables binding post and leading-out terminal binding post, corresponding upper cover two ends are also provided with end of incoming cables binding post mounting groove and leading-out terminal binding post mounting groove.During wiring, inlet wire and outlet are inserted in the square orifice of wire end line terminals and leading-out terminal binding post respectively, then firmly tighten the screw above binding post.But in rundown process, base, upper cover are easily by binding post distending, and especially side, end of incoming cables is particularly evident, make to form very large gap between base, upper cover, cause the water proof and dust proof of circuit breaker, security performance declines greatly.This phenomenon is also one of complained maximum problem of current circuit breaker, and tradition solves this problem usually by increasing the mode of connection rivet between base, upper cover, but effect is undesirable, and cost improves greatly.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of anti-distending miniature circuit breaker.
For solving the problem, the technical solution of the utility model comprises primarily of base, the housing of mini-type circuit breaker of upper cover composition, described base two ends are respectively equipped with end of incoming cables binding post mounting groove and leading-out terminal binding post mounting groove, end of incoming cables binding post and leading-out terminal binding post is separately installed with in end of incoming cables binding post mounting groove and leading-out terminal binding post mounting groove, corresponding upper cover two ends are also provided with end of incoming cables binding post mounting groove and leading-out terminal binding post mounting groove, it is characterized in that: the end of incoming cables binding post mounting groove outer ledge of described upper cover is provided with the first stiffened edge, the outside edge surfaces of this first stiffened edge medial surface and end of incoming cables binding post is arranged in opposite directions.
Described anti-distending miniature circuit breaker, is characterized in that: the end of incoming cables binding post mounting groove outer ledge of described base is provided with the second stiffened edge, and the outside edge surfaces of this second stiffened edge medial surface and end of incoming cables binding post is arranged in opposite directions.
Described anti-distending miniature circuit breaker, is characterized in that: the binding post mounting groove inside edge, end of incoming cables of described upper cover is provided with the 3rd stiffened edge, and the surface, inside edge of the 3rd stiffened edge medial surface and end of incoming cables binding post is arranged in opposite directions.
Described anti-distending miniature circuit breaker, is characterized in that: the binding post mounting groove inside edge, end of incoming cables of described base is provided with the 4th stiffened edge, and the surface, inside edge of the 4th stiffened edge medial surface and end of incoming cables binding post is arranged in opposite directions.
Anti-distending miniature circuit breaker of the present utility model, be provided with the first stiffened edge by the end of incoming cables binding post mounting groove outer ledge at upper cover, the outside edge surfaces of this first stiffened edge medial surface and end of incoming cables binding post is arranged in opposite directions.When firmly tightening binding post, the first stiffened edge medial surface can withstand the edge of end of incoming cables binding post, and its power is outwards disperseed, thus prevents the problem of the stressed backward two side distendings of base, upper cover.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is understructure schematic diagram of the present utility model;
Fig. 2 is superstructure schematic diagram of the present utility model.
Embodiment
As Fig. 1-2 shows, anti-distending miniature circuit breaker of the present utility model, comprise primarily of base 1, the housing of mini-type circuit breaker that upper cover 2 forms, described base 1 two ends are respectively equipped with end of incoming cables binding post mounting groove 3 and leading-out terminal binding post mounting groove 4, end of incoming cables binding post 5 and leading-out terminal binding post 6 is separately installed with in end of incoming cables binding post mounting groove 3 and leading-out terminal binding post mounting groove 4, corresponding upper cover 2 two ends are also provided with end of incoming cables binding post mounting groove 3 and leading-out terminal binding post mounting groove 4, end of incoming cables binding post mounting groove 3 outer ledge of described upper cover 2 is provided with the first stiffened edge 7, the outside edge surfaces of this first stiffened edge 7 medial surface and end of incoming cables binding post 5 is arranged in opposite directions.Also be provided with operating mechanism, tripping mechanism, contact mechanism, electromagnetic system and arc-control device in described miniature circuit breaker housing, these mechanisms are prior art, do not repeat at this.
For optimizing such scheme further, end of incoming cables binding post mounting groove 3 outer ledge of described base 1 is provided with the second stiffened edge 8, and the outside edge surfaces of this second stiffened edge 8 medial surface and end of incoming cables binding post 5 is arranged in opposite directions.The surface, inside edge that binding post mounting groove 3 inside edge, end of incoming cables of described upper cover 2 is provided with the 3rd stiffened edge the 9, three stiffened edge 9 medial surface and end of incoming cables binding post 5 is arranged in opposite directions.The surface, inside edge that binding post mounting groove 3 inside edge, end of incoming cables of described base 1 is provided with the 4th stiffened edge the 10, four stiffened edge 10 medial surface and end of incoming cables binding post 5 is arranged in opposite directions.By the setting of the second stiffened edge, the 3rd stiffened edge, the 4th stiffened edge, further increase the intensity of binding post mounting groove, playing further can by the problem of distending after preventing stressed skin.
In such scheme, the first stiffened edge, the second stiffened edge, the 3rd stiffened edge, the 4th stiffened edge and housing of mini-type circuit breaker be one-body molded, and the thickness of stiffened edge moves up and down as easily not affect terminated line terminal, and ideal thickness is 0.5-1mm.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection range of the present utility model.
