Abstract
The utility model relates to a test press-button on current leakage circuit breaker. The test press-button on current leakage circuit breaker comprises a sheath and a sheath cap. The utility model is characterized in that the test press-button also includes a press-button, a brass conductor, a test contact brass conductor and a test contact clamp. The test contact clamp contains a spring inside; one end of the spring is clamped onto the brass conductor; the other end is covered inside the contact clamp. The utility model of the test press-button on current leakage circuit breaker is characterized in sensitive response and simple structure. When the test press-button is pressed, the test contact clamp will contact the test contact brass conductor (when the zero line is connected with the power line), main purpose of which is to see whether current leakage protection takes effects.
Description
Technical field
The utility model relates to the low-voltage electrical apparatus field, relates in particular to a kind of residual current circuit breaker, particularly a kind of test button of residual current circuit breaker.
Background technology
In order to ensure Electrical Safety, the application of residual current circuit breaker be at present very extensively.In order to prevent the generation of electric leakage accident, with the general function of automatically cutting off of circuit when adopting residual current circuit breaker to realize leaking electricity in the electric line.Test button is arranged on and is used for the parts that the test both opens device whether can operate as normal on the residual current circuit breaker.
Summary of the invention
The purpose of this utility model is to provide a kind of reflection sensitive, the test button of residual current circuit breaker simple in structure.
In order to solve the problem that exists in the background technology, the utility model adopts following technical scheme:
A kind of test button of residual current circuit breaker, comprise sheath, sheath lid, being provided with the test contact in the sheath buckles, it is characterized in that test button comprises that also button, conduction latten(-tin), test contact latten(-tin) contact button with test, be provided with spring in the test contact button, spring one end is buckled on the conduction latten(-tin), and an end is buckled in the contact button.
The conduction latten(-tin) is provided with long pin spring, is connected to live wire by long pin spring.
Be welded with test resistance on the test contact latten(-tin) and be connected to zero line.
The test button of a kind of residual current circuit breaker of the utility model; have be quick on the draw, characteristic of simple structure; when pressing test button, test contact snapping contacts (this moment, change communicated with live wire) on the test contact latten(-tin), mainly see the earth leakage protective effect of playing?
