The utility model discloses simple structure, the action of threading off is rapidly sensitive.
Description
Technical field
The utility model relates to a kind of high-breaking miniature breaker, is specifically related to a kind of trip gear of high-breaking miniature breaker.
Background technology
High-breaking miniature breaker plays the effect of overload and short-circuit protection in electric wiring, has isolated from power function simultaneously.The high-breaking miniature breaker of prior art, generally with disengaging deivce of earth leakage, but shortcoming to be the structure of disengaging deivce of earth leakage quite complicated, and action owes rapidly sensitive.
Summary of the invention
For the deficiency that prior art exists, it is simple that the purpose of this utility model is to provide a kind of structure, the sensitive tripping device for circuit breaker rapidly of trip action.
The utility model is implemented by following technical solution:
Tripping device for circuit breaker, be included in the reset button that base is installed, electric leakage coil and dropout actuated piece, back-moving spring is equipped with in the inside of reset button, it is characterized in that: dropout actuated piece rotates to be located on base, dropout actuated piece is made up of the first fork be fixedly connected with and the second fork, first fork is laid close to vertical direction, the top of the first fork is provided with open slot, the medial extremity of the first fork is provided with dropout groove, electric leakage coil and reset button are respectively in the left and right sides of the first fork, dynamic iron core and return spring is provided with in electric leakage coil, the head of dynamic iron core is provided with connecting rod activity through open slot, the first fork is driven to swing during dynamic iron core action, the limit, left side of reset button is fixed with the dropout fixture block of corresponding dropout groove, circuit breaker is not when leaking electricity, dropout groove blocks dropout fixture block.
In such scheme, dropout actuated piece only has two forks, and structure is very simple, and wherein the top of the first fork is provided with open slot, medial extremity is provided with dropout groove, and open slot mates with the dynamic iron core of the coil that leaks electricity, and dropout groove mates with the dropout fixture block of reset button, when not leaking electricity, dropout groove blocks dropout fixture block, trip gear is in non-action state, and when there is electric leakage, electric leakage coil has electricity to pass through, both dynamic iron core action had been driven, dynamic iron core pulls the first fork to swing left to make dropout groove leave dropout fixture block again, so reset button pops up under the effect of back-moving spring, not only can play the effect of prompting accident, the active force of what is more important back-moving spring can pass through dropout fixture block simultaneously, dropout fixture block promotes the first fork by dropout groove and swings left, improve the swing speed of the first fork, make trip action more rapidly sensitive.
As preferably, the offset angular between the first fork, the second fork is 115-125 degree.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structure chart of the present utility model,
Fig. 2 is the rear view of reset button in Fig. 1, electric leakage coil and dropout actuated piece.
Embodiment
As shown in the figure, tripping device for circuit breaker of the present utility model, comprise the reset button 7 of installing on the pedestal 11, electric leakage coil 2 and dropout actuated piece, back-moving spring 8 is equipped with in the inside of reset button 7, dropout actuated piece is rotated by rotating shaft 9 to be located on base 11, dropout actuated piece is made up of the first fork 4 be fixedly connected with and the second fork 10, first fork 4, offset angular between second fork 10 is 115-125 degree, first fork 4 is laid close to vertical direction, the top of the first fork 4 is provided with open slot 41, the medial extremity of the first fork 4 is provided with dropout groove 42, electric leakage coil 2 and reset button 7 are respectively in the left and right sides of the first fork 4, dynamic iron core 3 and return spring 1 is provided with in electric leakage coil 2, the head of dynamic iron core 3 is provided with connecting rod 6 activity through open slot 41, the first fork 4 is driven to swing during dynamic iron core 3 action, the limit, left side of reset button 7 is fixed with the dropout fixture block 5 of corresponding dropout groove 41, circuit breaker is not when leaking electricity, dropout groove 41 blocks dropout fixture block 5.
The course of work of the present utility model is: when not leaking electricity, dropout groove blocks dropout fixture block, trip gear is in non-action state, and when there is leak current fault, electric leakage coil has electricity to pass through, both driven dynamic iron core action, dynamic iron core pulls the first fork to swing left to make dropout groove leave dropout fixture block, so reset button pops up under the effect of back-moving spring again; When leak current fault is disposed, dynamic iron core promotes the right pendulum of the first fork under return spring effect, and at this moment press reset button, dropout fixture block can reenter in dropout groove.
