Embodiment
In order to which technical scheme described in the utility model is expanded on further, with reference to Figure of description, tool of the present utility model
Body embodiment is as follows：
As shown in Figure 1, Figure 2 and Figure 3, the utility model provides a kind of automobile-used reset breaker, the reset breaker
By combination hub 1, reset Shell of circuit breaker 2, SR 3, fixed contact piece 4, SR spring 5, movable contact connection sheet 6, dynamic
Contact piece 7 forms；
Combination hub 1 is automobile-used breaker standard combination hub, and remaining building block of the breaker is arranged at reset and broken
In road device housing 2；The combination hub 1 is connect by buckle with resetting the clamping of Shell of circuit breaker 2, the patch piece of the combination hub 1
Spigot is exposed at the outside for resetting Shell of circuit breaker 2, and the connection end of patch piece is divided positioned at the inside for resetting Shell of circuit breaker 2
It is not connected, and then is realized to multiple with one end of fixed contact piece 4 in reset Shell of circuit breaker 2 and one end of movable contact connection sheet 6
The support of fixed contact piece 4 and movable contact connection sheet 6 in the Shell of circuit breaker 2 of position；
As shown in figure 4, the movable contact piece 7 is to become the stamping forming laminated structure of conductive material, the movable contact by temperature
Piece 7, which is arranged on, to be resetted in Shell of circuit breaker 2, and one end of movable contact piece 7 rivets with the other end end of movable contact connection sheet 6, moves and touches
The other end of spot film 7 is provided with the movable contact of outwardly convex, and the other end of fixed contact piece 4 is provided with the fixed contact of outwardly convex, dynamic
Under the material forces effect of contact piece 7, movable contact is in close contact with fixed contact；Movable contact is in contact with fixed contact and realizes circuit
Conducting, movable contact isolate the blocking for realizing circuit with fixed contact；
As shown in Figure 1, Figure 2 and Figure 3, the top of the SR 3 is turret terminal, and turret terminal is from resetting Shell of circuit breaker
2 top is stretched out, and is exposed at the outside for resetting Shell of circuit breaker 2, the lower section of SR 3 is insulating end, and the insulating end is
Insulating trip, the bottom of the insulating trip are supported by SR spring 5；The top of the SR spring 5 and insulating trip
At bottom connection, the bottom of SR spring 5 is acted against on the inner surface for resetting Shell of circuit breaker 2；Open circuit is resetted when described
When device is not triggered, the insulating trip is located at below the contact point of fixed contact and movable contact；The insulating trip, fixed contact touch with dynamic
The contact point of point and the axial direction of SR spring 5 be in same plane, when the breaker that resets is triggered, fixed contact
When occurring gap between movable contact, in the presence of the SR spring 5 under compressive state, it is fixed that insulating trip will insert
Between contact and movable contact, realize that contact obstructs.In addition, when the insulating trip of the bottom of SR 3 button spring 5 that is reset is upspring
Afterwards, the turret terminal on the top of SR 3 is taken advantage of a situation and also upspring, to prevent SR 3 from popping up excess, in SR 3
