A kind of miniature circuit breaker with energy storage device of the utility model, including handle, rocking arm, back-moving spring, drive link,
Support member, the tripping being installed on support member and lock, moving contact, static contact and touch spring and pedestal, the rocking arm with
The handle is arranged concentrically on the pedestal, the action of reset spring in being provided with cantilever on the handle, the rocking arm,
Cantilever can keep engagement or separate with pedestal, and stop face is provided with the rocking arm, and the stop face is dynamic in setting position limitation
Contact displacement.
Preferably, the moving contact is provided with stop flange, and the rocking arm stop face acts on moving contact stop flange.
Preferably, the action of reset spring is between handle and rocking arm；Or, the action of reset spring in pedestal with
Between rocking arm.
Preferably, the touch spring is acted between the moving contact and the support member.
Miniature circuit breaker of the present utility model with stored energy mechanism, is done by rocking arm and moving contact in the position of setting
Engagement is related to, moving contact quick-make during breaker closing is not only realized, due to the uniformity of the position of engagement, while improve
Energy storage reliability, also certain amplitude reduce operating force

Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in figs. 1-7, the utility model provides a kind of miniature circuit breaker with energy storage device, including handle 1, rocking arm
2, back-moving spring 3, drive link 4, support member 5 is installed on tripping 51 on support member 5 and lock 52, moving contact 6, static contact 7 with
And touch spring 8 and pedestal 9, it is characterised in that：Rocking arm 2 is arranged concentrically on pedestal 9 with handle 1, and back-moving spring 3 is acted on
Cantilever 21 is provided with handle 1, rocking arm 2, cantilever 21 can keep engagement or separate with pedestal 9, and stop face is provided with rocking arm 2
22, stop face 22 limits the displacement of moving contact 6 in setting position.
Further, moving contact 6 is provided with stop flange 61, and rocking arm stop face 22 acts on moving contact stop flange 61.
Further, back-moving spring 3 is acted between handle 1 and rocking arm 2；Or, back-moving spring 3 acts on pedestal 9 with shaking
Between arm 2.
Further, touch spring 8 is acted between moving contact 6 and support member 5.
Miniature circuit breaker stored energy mechanism of the present utility model, rotary handle 1 can realize that moving contact 6 is leaned on respect to static contact 7
Near or separately action, i.e. the switch closing and switch opening process of contact, when handle 1 is carried out in making process, moving contact 6 moves to setting position
