Abstract
The utility model relates to a small circuit breaker, solving the problems that tripping mechanisms of conventional small circuit beakers cannot be switched on rapidly and thereby contacts are burned out. In the utility model, a rotor is disposed at the inner side of a handle and is in peripheral driving fit with the handle. A pinch plate is hinged at the inner side of a housing. One end of the pinch plate is connected with the housing via an elastic piece, and the other end of the pinch plate is clamped with the rotor. The pinch plate is provided with an inclined surface thereon. The pinch plate rotates and is matched with the periphery of the handle through the inclined surface so as to cause peripheral rotation of the handle. Due to the addition of a switch-on boosting mechanism at the handle, a tripping mechanism can be driven to be switched on rapidly when the circuit breaker is switched on, realizing the effect of instantly switching on a contact, effectively preventing the contact from being burned out and prolonging the service lifetime of products.
Description
Technical field
The utility model relates to a kind of electric circuit protection equipment, refers in particular to a kind of miniature circuit breaker with rapid closing function.
Background technology
Miniature circuit breaker is widely used in circuit control appliance field, during combined floodgate, drive the tripping mechanism action by handle and realize the purpose of combined floodgate so that moving contact contacts with fixed contact, can combined floodgate moment, fast, to directly affect the useful life of contact, if tripping mechanism action is rapid not, will be to produce pyrophoric continuation between moving contact and the fixed contact longer, cause contact to be burned, thereby reduced the useful life of product.
Summary of the invention
For the shortcoming and the weak point that overcome background technology, the utility model provides a kind of miniature circuit breaker.The tripping mechanism that solves existing miniature circuit breaker can not carry out rapid closing, the problem that causes contact to be burned.
The technical solution of the utility model is: a kind of miniature circuit breaker, comprise housing, be provided with handle in the described housing, tripping mechanism, moving contact and fixed contact, described handle and tripping mechanism are connected, described moving contact is connected with tripping mechanism, described fixed contact matches with moving contact, the inboard of described handle is provided with the rotor that cooperates with the circumferential transmission of its formation, the hinged inside of described housing has buckle, one end of described buckle is connected with housing by elastic component, the other end and the rotor of described buckle fasten, and described buckle is provided with the inclined plane, and described buckle rotates by described inclined plane and cooperates the formation handle circumferentially to rotate with the periphery of handle.
The lower left corner of described handle is fixed with bearing pin, described buckle is articulated on the described bearing pin, and the left end of described buckle is connected with the housing inboard by spring, right-hand member and the rotor of described buckle fasten, the upside of buckle is located on described inclined plane, and described buckle clockwise rotates around bearing pin and presses the periphery of handle to consist of handle by top, described inclined plane and rotates counterclockwise.
The outside of described handle is provided with breach, and described rotor is provided with the fixture block that is connected with its one, and described fixture block is positioned at described breach, and described buckle is provided with the barb that fastens with described fixture block.
The utlity model has following beneficial effect: since in the increase at handle place the combined floodgate boosting mechanism, thereby so that circuit breaker can drive the tripping mechanism rapid closing when closing a floodgate, realize the effect of contact moment combined floodgate, prevent that effectively contact is burned, improved the useful life of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structure enlarged drawing at A place among the utility model Fig. 1.
Among the figure, housing 1, handle 2, tripping mechanism 3, moving contact 4, fixed contact 5, rotor 6, fixture block 61, buckle 7, barb 71, elastic component 8, inclined plane 9, bearing pin 10.
Embodiment
The below is described further embodiment of the present utility model for accompanying drawing:
Shown in figure, this miniature circuit breaker, comprise housing 1, be provided with handle 2 in the described housing 1, tripping mechanism 3, moving contact 4 and fixed contact 5, described handle 2 is connected with tripping mechanism 3, described moving contact 4 is connected with tripping mechanism 3, described fixed contact 5 matches with moving contact 4, the inboard of described handle 2 is provided with the rotor 6 that cooperates with the circumferential transmission of its formation, the hinged inside of described housing 1 has buckle 7, one end of described buckle 7 is connected with housing 1 by elastic component 8, the other end of described buckle 7 and rotor 6 fasten, and described buckle 7 is provided with inclined plane 9, and described buckle 7 rotates by described inclined plane 9 and cooperates formation handle 2 circumferentially to rotate with the periphery of handle 2.According to such scheme and since in the increase at handle place the combined floodgate boosting mechanism, thereby so that circuit breaker when closing a floodgate, can drive the tripping mechanism rapid closing, realize the effect of contact moment combined floodgate, prevent that effectively contact is burned, improved the useful life of product.
In the utility model, as shown in the figure, the lower left corner of described handle 2 is fixed with bearing pin 10, described buckle 7 is articulated on the described bearing pin 10, and the left end of described buckle 7 is connected with housing 1 inboard by spring, the right-hand member of described buckle 7 and rotor 6 fasten, and the upside of buckle 7 is located on described inclined plane 9, and described buckle 7 clockwise rotates around bearing pin 10 and presses the periphery of handle 2 to consist of handle 2 by 9 tops, described inclined plane and rotates counterclockwise.The outside of described handle 2 is provided with breach 11, and described rotor 6 is provided with the fixture block 61 that is connected with its one, and described fixture block 61 is positioned at described breach 11, and described buckle 7 is provided with the barb 71 that fastens with described fixture block 61.Handle 2 is positioned on the right positions, at this moment, be under the gate-dividing state, moving contact 4 separates with fixed contact 5, when needs close a floodgate, handle 2 is pulled left to be counterclockwise and is rotated, because the fixture block 61 on the rotor 6 is positioned at the breach 11 of handle 2, and fixture block 61 matches with barb 71, so handle 2 rotates drive buckle 7 and rotates counterclockwise around bearing pin, spring is stretched, handle 2 goes to its outside and fits with the inclined plane 9 of buckle 7, when being rotated further, and the inclined plane 9 of the peripheral top clinching plate 7 by handle 2, so that buckle 7 breaks away from rotor 6, and under the effect of spring, reset to be and clockwise rotate, the outside portion of the upper end extrusion handle 2 by inclined plane 9, thus realize the purpose of boosting handle 2 quick rotation, close a floodgate rapidly, prevent that effectively contact is burned.
Embodiment should not be considered as the restriction to utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
