Specific embodiment
The embodiment of the present invention is provided below in conjunction with attached drawing 1 to 24, further illustrates the operation machine of breaker of the invention
Structure specific embodiment.The operating mechanism of breaker of the invention is not limited to the following description.
Breaker of the invention includes the handle 2, link assembly 3, movable connector 4, push-rod assembly being mounted in shell 1
5, bimetal leaf 6, electromagnetic system 7 and fixed contact therefor 8.One end of link assembly 3 and handle 2 are drivingly connected in Fig. 1, connection rod set
The other end of part 3 and movable connector 4 overlap, and handle 2 can drive link assembly 3 to drive the rotation of movable connector 4 and then and solid
Determine contact 8 and be contacting and separating to realize the closure and disjunction of breaker.Also, it is equipped between handle 2 and shell 1 for driving
The first spring 200 that handle 2 resets, is equipped with the second spring for positioning linkage rod component 3 between link assembly 3 and shell 1
300, the third spring 400 for driving movable connector 4 to reset, third bullet are also equipped between movable connector 4 and shell 1
Spring 400 is mounted between handle 2 and electromagnetic system 7.It one end of the push-rod assembly 5 can be with the electromagnetic system for instantaneous protection
7 and for delay protection effect bimetal leaf 6 be drivingly connected, the other end of push-rod assembly 5 can be with 3 company of contact of link assembly
It connects, bimetal leaf 6 and electromagnetic system 7 can make push-rod assembly 5 be placed in trip positions, so that handle 2 can not close a floodgate.The present invention
Handle be directly drivingly connected with movable connector by link assembly, reduce the part of operating mechanism, simplify breaker
Mounting structure, and then improve assembly efficiency and stability.Further overlapped using movable connector 4 and positioning linkage rod component 3,
The mode that push-rod assembly 5 and link assembly 3 connect realizes that stacked structure is convenient for the Automated assembly of breaker, together
When ensure that the stability of link assembly Yu movable connector drive actions.
Link assembly 3 of the invention and the overlap joint of movable connector 4 refer to do not have between link assembly 3 and movable connector 4
Buckle, axis hole etc. are similar to be fastened and connected, and is only that the clinch 440 of movable connector 4 is placed on the overlap joint notch of link assembly 3
In 331, this overlapped stratification position relationship is particularly conducive to automation installation and not high to the required precision of installation.Specifically
Ground, the end of movable connector 4 are equipped with the clinch 440 connected with the overlap joint notch 331 on link assembly 3, and overlap joint lacks
331 sides of mouth are equipped with protruding features.During handle 2 drives breaker closing, handle 2 drives link assembly 3 mobile, takes
When socket part 440 is relatively moved and limited by protruding features along overlap joint notch 331, protruding features can be with the end phase of clinch 440
Interaction can push clinch 440 mobile to drive the rotation of movable connector 4 to complete to close a floodgate.And overlap the another of notch 331
A side edge, which is additionally provided with, is used to support and limits the overlap joint limited wall 332 that clinch 440 moves, and overlap joint notch 331 further includes setting
It sets and is connected with protruding features for limited wall 332 will to be overlapped in overlap joint 331 side wall of notch and is used to limit taking for clinch 440
Junction 336 is taken so that clinch 440 is placed in by what faying surface 336, protruding features and overlap joint limited wall 332 collectively formed
