The utility model content

The utility model technical problem to be solved is that the leakage tests that a kind of RCCB will be provided is the device of one with the electric leakage SR.

In order to solve above technical problem; It is the device of one that the utility model provides a kind of leakage tests of RCCB and electric leakage SR; This RCCB comprises test circuit, operating grip, test reset button, test reset spring, electric leakage lock, electric leakage lock spring, axle, testing conductive spring and the brass tube that framework, electric leakage simulation take place; Said test reset button exceeds the part of framework and divides two-layer up and down; The upper strata is the T deck sections, is used for leakage tests and electric leakage reset operation; Lower floor is the R deck sections, has the indication of electric leakage state; Test reset button lower knuckle, and protrude into the holding section in the bottom, this holding section engages interlock with the protruding clamping part of electric leakage lock seaming; The test circuit that said electric leakage simulation takes place has double break point and breaks off defencive function.R deck sections and framework maintain an equal level and represent not have electric leakage, are normal operating conditions; The leakage tests of test reset button is that the test reset button forces testing conductive spring one end to contact with brass tube, and it is to realize through test reset button and the interlock of electric leakage lock that the electric leakage of test reset button resets.

Said test reset button middle part is provided with spring groove, is equipped with back-moving spring in the spring groove.

Said electric leakage lock, the protruding clamping part in limit is arranged at its top, and the protruding clamping part in this limit engages interlock with test reset button clamping part, and there is round tube hole at the middle part, rotates in the insertion round tube hole, and the bottom is useful on the round protuberance that impacts snap close.When electric leakage, the release action clockwise rotates the electric leakage lock, and bottom circle protuberance just impacts the RCCB snap close, and snap close is separated with tripping, leaks electricity and breaks off protection; Simultaneously; The clamping part of the protruding clamping part of upper edge of electric leakage lock and test reset button bottom breaks away from; Force electric leakage lock bottom circle protuberance to promote the tripping that the RCCB snap close is opened RCCB always; Switch is in break off and can not closure state always, has only through pressing the test reset button and remove the effect of electric leakage lock, switch could operate as normal.

The circular arc protuberance is arranged at said handle bottom, and when the RCCB "on" position, the handle protuberance forces the testing conductive spring to contact with brass tube, and when the RCCB off-state, contact keeps breaking off.

The test circuit that said electric leakage simulation takes place has double break point and breaks off defencive function; Test reset button push testing conductive spring contacts with brass tube in the leakage tests circuit and constitutes a breakpoint, and another breakpoint is that the handle protuberance forces the testing conductive spring to contact formation with brass tube in the electronic circuit board supply line.

The superior effect of the utility model is:

1) shelves mobile the variation through the test reset button, can realize the difference in functionality of test reset button; When test reset button during in a high position, the expression RCCB is in the electric leakage state; When test reset button during in the centre position, expression is in normal condition; When the test reset button moves down certain position, realize that analog current flows through test circuit and reaches the earth leakage protective reliable in action property of detection;

2) the utility model is combined into one the test button and the instruction button that resets, and simple in structure, the bodily form is little, can be used in the less RCCB of volume, and makes mistakes in the turnover wiring through handle protuberance breakpoint protection circuit plate and can avoid burning.
