Abstract
The utility model provides a kind of moving contact component of circuit breaker, it comprises moving contact rack and moving contact, described moving contact is located on described moving contact rack, the upper end of described moving contact rack be provided be used to indicate circuit breaker be in be switched on or switched off state of switch state instruction look, the lower end of described moving contact rack is provided with two grip blocks, a projection is also connected with between two described grip blocks, described moving contact is provided with and forms the hinged groove be rotatably assorted with described projection, described moving contact is also provided with the support end extended between insertion two grip block, and two described grip blocks formations grip the axis of described moving contact upper end, described moving contact lower end correspondence be provided with can with the projection of fixed contact reliable contacts, described moving contact is also connected with the back-moving spring that its hinged rotation can be made to reset afterwards.The utility model structure is simple, it is more reliable to use.
Description
Technical field
The utility model relates to a kind of moving contact component of circuit breaker.
Background technology
The contact system of current circuit breaker on the market is generally divided into moving contact and fixed contact two parts, namely fixed contact is fixed on the pedestal of circuit breaker, moving contact is fixed on moving contact rack, moving contact is driven to move within the specific limits by the motion of moving contact rack, by the contact of moving contact and fixed contact or be separated the object reaching and connect or disconnect circuit breaker.The moving contact of conventional circuit breaker is all be articulated with on moving contact rack, but lacks axial limiting between moving contact and moving contact rack.Therefore, moving contact can be made to produce axial endplay when moving contact rotates, just may loose contact between moving contact and fixed contact, thus make circuit breaker cannot normally disjunction.
Summary of the invention
For the deficiencies in the prior art, the utility model provides the moving contact component that its structure a kind of is simple, use more reliable circuit breaker.
For achieving the above object, the utility model provides a kind of moving contact component of circuit breaker, it comprises moving contact rack and moving contact, described moving contact is located on described moving contact rack, the upper end of described moving contact rack be provided be used to indicate circuit breaker be in be switched on or switched off state of switch state instruction look, the lower end of described moving contact rack is provided with two grip blocks, a projection is also connected with between two described grip blocks, described moving contact is provided with and forms the hinged groove be rotatably assorted with described projection, described moving contact is also provided with the support end extended between insertion two grip block, and two described grip blocks formations grip the axis of described moving contact upper end, described moving contact lower end correspondence be provided with can with the projection of fixed contact reliable contacts, described moving contact is also connected with the back-moving spring that its hinged rotation can be made to reset afterwards.
The beneficial effects of the utility model are: the lower end due to described moving contact rack is provided with two grip blocks, and two described grip block correspondence formations grip the axis of described moving contact upper end, therefore in the moving contact rack drive hinged rotation of moving contact and in moving contact reseting procedure, can effectively prevent moving contact from moving contact rack, axial endplay occurring, thus the loose contact problem also just effectively avoiding dynamic and static contact to produce because of axial endplay, and then make circuit breaker more reliablely and stablely can carry out disjunction.
Because described moving contact rack lower end is provided with two grip blocks, moving contact is had to the effect axially gripped, effectively can prevent the axial endplay of moving contact.When circuit breaker is from being disconnected to closed process, described moving contact rack utilizes the active force of projection to moving contact that moving contact is rotated towards fixed contact in rotation process, and the back-moving spring now on moving contact is in tensioned state; When circuit breaker is from the process being closed into disconnection, the projection of moving contact rack no longer applies active force to moving contact, thus moving contact rotates away from fixed contact under the pulling force of the back-moving spring tightened.
The utility model can be set to two described grip blocks further and be shaped on described moving contact rack, processes and assemble up convenient.

Fig. 2 is exploded perspective view of the present utility model;
Fig. 3 is perspective view of the present utility model;
Fig. 4 is the schematic diagram of A-A section in Fig. 3 of the present utility model.
Embodiment
As Fig. 1, 2, 3, a kind of moving contact component of circuit breaker is given shown in 4, comprise moving contact rack 1 and moving contact 2, described moving contact 2 is located on described moving contact rack 1, the upper end of described moving contact rack 1 is provided with on off state instruction look 11, the lower end of described moving contact rack 1 is provided with two grip blocks 13, a projection 14 is also connected with between two described grip blocks 13, described moving contact 2 is provided with and forms the hinged groove 22 be rotatably assorted with described projection 14, described moving contact 2 is also provided with the upper end extended between insertion two grip blocks 13, and described two grip blocks 13 form and grip the axis of described moving contact 2 upper end, the lower end correspondence of described moving contact 2 is provided with the projection 23 that can match with fixed contact 5, described moving contact 2 is also connected with the back-moving spring 21 that its hinged rotation can be made to reset afterwards.
The present embodiment can be set to two described grip blocks 13 further and be shaped on described moving contact rack 1.
The middle part that the present embodiment can be set to described moving contact rack 1 further is also provided with a through hole 3, described through hole is hinged with the tripping 4 for driving moving contact rack to rotate.
Combine accompanying drawing to be above explained in detail execution mode of the present utility model, but the utility model is not limited to above-mentioned execution mode, in addition, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from present inventive concept.
Claims (3)
