Abstract
The utility model relates to a kind of circuit breaker, relates in particular to a kind of operating mechanism of small-sized residual current circuit breaker.The operating mechanism of this small-sized residual current circuit breaker comprises operating mechanism support, an operating grip and a handle back-moving spring, also is provided with a kinematic link, and an end of kinematic link is eccentrically set on the handle, and the other end is connected with tripping; Also be provided with top board on the operating mechanism support, the top of top board is provided with button again, and realizes mechanical chain with spring and extension spring.Improve the mechanism of operating mechanism, made small-sized residual current circuit breaker have more associative perception, and saved the part material, reduced production cost, improved respond.
Description
Technical field
The utility model relates to a kind of circuit breaker, relates in particular to a kind of operating mechanism of small-sized residual current circuit breaker.
Background technology
At present, the kind of the residual current circuit breaker on the market is a lot, but also there is a lot of problems in the general especially small-sized residual current circuit breaker of circuit breaker, also is not very stable on performance.The operating mechanism complex structure of present miniature circuit breaker, the Motion Transmission route is long, and reaction is sensitive inadequately.And the release on the operating mechanism of present small-sized residual current circuit breaker is because the problem equipped with circuit breaker, release is generally all installed than operating mechanism height, caused like this shell of residual current circuit breaker must design out-of-flatness, the shell that one side of release is installed wants high relatively, when this residual current circuit breaker and other circuit breaker fit together, will lack associative perception, influence the attractive in appearance of integral body.
Summary of the invention
The purpose of this utility model is to provide a kind of operating mechanism of simple in structure, the small-sized residual current circuit breaker that is quick on the draw.
Have defective in the background technology in order to overcome, the utility model adopts following technical scheme:
A kind of operating mechanism of small-sized residual current circuit breaker comprises operating mechanism support, an operating grip and a handle back-moving spring, also is provided with a kinematic link, and an end of kinematic link is eccentrically set on the handle, and the other end is connected with tripping; Also be provided with top board on the operating mechanism support, the top of top board is provided with button again, and realizes mechanical chain with spring and extension spring.Mechanical mechanism is simple, has reduced the Motion Transmission route, has improved reaction speed.
One side of operating mechanism support is provided with test bracket, and test bracket is provided with test button.
Described test button comprises the column-shaped projection that is provided with again on the test bracket, and the top of this column-shaped projection is provided with barb, and column-shaped projection is provided with little spring, and button is arranged on the little spring.The long-term use of this test button also is not easy to cause owing to camber of spring loses efficacy test button to be lost efficacy, and has improved useful life.
The operating mechanism support is provided with indicator board.Can clearly reflect the operating state of circuit breaker.
Operating mechanism support one side is equipped with release, and the top of this release is lower than the operating mechanism support.This structure makes the shell of its small-sized residual current circuit breaker can design more smoothly, has more associative perception when small-sized residual current circuit breaker and other circuit breaker are assembled together.
The utility model makes small-sized residual current circuit breaker have more associative perception, and has saved the part material from improving the mechanism of operating mechanism, has reduced production cost.
