Description
Technical field
The present invention relates to a kind of circuit breaker components, particularly a kind of test button device of residual current circuit breaker.
Background technology
Along with our people is to the requirement of the deep understanding of electricity consumption and China's electric power system, residual current circuit breaker has been indispensable protective circuit breaker in people's lives; Installing and using in specification GB13955 clear stipulaties residual current circuit breaker test button device in residual current circuit breaker must monthly by once, guarantee that residual current circuit breaker leakage function is whether normal, thus need long, accurately reliable, the requirement such as electric clearance is large residual current circuit breaker test button device lifetime.
Residual current circuit breaker test button device is become by two panels test film, test button, a test turriform groups of springs in the market, and test film material is respectively tin bronze.There is the defects such as electric clearance is little, cost is high, the life-span is short in this test button device.
Summary of the invention
There is to solve existing residual current circuit breaker test button device the problem that electric clearance is little, cost is high, the life-span is short, the invention provides a kind of test button device of residual current circuit breaker, improve the reliability that residual current circuit breaker leakage function detects.
The technical solution adopted in the present invention is: a kind of test button device of residual current circuit breaker, it comprises base, test button, test spring and contact chip, installation test button on the shell of described base, the bottom of described test button and the end thereof contacts of test spring, the lower end of described test spring arranges contact chip, described test spring adopts the design of torsion spring, the bending of described test spring one end forms bending segment, the axis of described bending segment parallels with contact chip, described test button, the bending segment of test spring and contact chip form test button and press, the cooperation that the bending segment of test spring contacts with contact chip.
The groove suitable with test spring is had bottom described test button.
The present invention adopts the Parallel Design of test spring and contact chip, increase the electric clearance of test spring and test film, thus improve the electric clearance of test button device, add test button equipment safety, test spring adopts torsion spring design simultaneously, improve test button device useful life, also reduce residual current circuit breaker test button installation cost simultaneously.
Accompanying drawing explanation
Fig. 1 is plane graph of the present invention.
Fig. 2 is the enlarged drawing at the A place in Fig. 1.
Fig. 3 is the structural representation of test spring.
In figure, 1-test button, 2-base, 3-test spring, 4-contact chip, 31-bending segment.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention is further illustrated:
As depicted in figs. 1 and 2, a kind of test button device of residual current circuit breaker, it comprises base 2, test button 1, test spring 3 and contact chip 4, installation test button 1 on the shell of described base 2, the bottom of described test button 1 and the end thereof contacts of test spring 3, the lower end of described test spring 3 arranges contact chip 4, described test spring 3 adopts the design of torsion spring, the bending of described test spring 3 one end forms bending segment 31, described bending segment 31 parallels with contact chip 4, guarantee test spring 3 is depressed and is always linear contact lay with contact chip 4, described test button 1, the axis of the bending segment 31 of test spring 3 and contact chip 4 form test button 1 and press, the cooperation that the bending segment 31 of test spring 3 contacts with contact chip 4.
Have the groove suitable with test spring 3 bottom described test button 1, make the bottom tabling of test spring 3 and test button 1, what prevent test spring 3 from departing from test button 3 presses down route, and avoid when test button 3 is pressed, contactless phenomenon occurs.
When test button 1 is subject to downward pressure, and when this pressure is greater than test spring 3 normal condition torsion upwards, test spring 3, when being under pressure, moving downward and contacts with contact chip 4, achieves the reliable contacts of test button 1.And be linear contact lay because test spring 3 contacts with contact chip 4, improve contact reliability.
See Fig. 3, test spring 3 have employed the design of torsion spring, and this torsion spring has 2 large functions in test button device.One is under the effect of torsion spring, can make test button 1 return, fakes return spring function and uses; Two is when contacting with contact chip 4, is as conductor function.From these two functions, this test spring 3 improves the useful life of test button device, also reduces the cost of the test button device of residual current circuit breaker simultaneously.
Because contact chip 4 and the bending segment 31 of test spring 3 are Parallel Design, can by regulating the angle of torsion spring, increase the electric clearance between test spring 3 and contact chip 4, thus improve the electric clearance of test button device, add test button equipment safety.
Comprehensive above-mentioned test button apparatus design scheme summary is known, and this test button device scheme has that cost is low, the life-span is long, reliability is high, fail safe advantages of higher, is conducive to China's residual current circuit breaker development.
Embodiment should not be considered as limitation of the present invention, but any improvement done based on spirit of the present invention, all should within protection scope of the present invention.
