Abstract

The invention discloses an operating mechanism of a leakage protector, which comprises a pedestal, a drive contact component, a driven contact component, a coil frame and a drive armature, wherein the drive contact component, the driven contact component, the coil frame and the drive armature are arranged on the pedestal; the pedestal is provided with two coaxial drive contact seat mounting holesand a fan-shaped backing stage; the drive contact component is connected with the drive contact seat mounting holes reserved on the pedestal by a drive contact seat connecting piece, and is positioned on the drive contact seat backing surface of the fan-shaped backing stage by a drive contact seat spring; and the drive contact component is connected with driven bracket mounting holes on the pedestal by a driven bracket mounting half shaft, and positions a driven bracket onto the pedestal by a driven bracket spring. The joint closing mode of the operating mechanism is rotating closing which refers to that overrunning parts of drive joints and driven joints perform shearing friction motions in closing and separation so as to realize the functions of increasing the contact areas of the joints and self-cleaning the joints and effectively improve the electrical endurance of the product.

Description

technical field [0001] The present invention relates to a kind of reset operation through the drive button, so that the active contact and the passive contact are closed, and when the leakage current flows, the circuit board component controls the electromagnetic system to lose power, so that the active contact and the passive contact are separated. The operation has the leakage protection function mechanism. Background technique [0002] At present, there are different types of operating mechanisms of earth leakage protectors on the market. The contact closure form of the operating mechanisms of earth leakage protectors is generally a horizontal or vertical linear motion, such as the release of the earth leakage protection plug described in ZL patent code 02218282.9. Buckle mechanism, in this kind of tripping mechanism, the iron core directly drives the lock to lock the cross arm. Because the iron core and the lock move in the same direction and are perpendicular to the mov...
