Mechanical tripping mechanism for earth leakage protection socket

Abstract

The invention discloses a mechanical tripping mechanism for an earth leakage protection socket. The mechanical tripping mechanism comprises a support, a tripping cam, a tripping plate, a rotating wheel and a wiring rocker, the tripping cam is arranged at the top of the support in a rotatable mode, the tripping cam is connected with a knob, the tripping plate swings right and left on one side of the tripping cam and is reset through a first torsion spring, under the effect of the torsion of the first torsion spring, the swing end of the tripping plate butts against the cam surface of the tripping cam, the rotating wheel is arranged in the support in a rotatable mode and reset through a second torsion spring, the rotating wheel is provided with a convex locking edge, and the tripping plate is provided with a locking orifice. When the mechanical tripping mechanism is in a state before tripping, the locking orifice is buckled by the convex locking edge, the wiring rocker is arranged in an up-and-down swinging mode below the rotating wheel, the wiring rocker is connected with the rotating wheel through a connecting rod, the rotating wheel is provided with a poking rod stretching to the lower end of the tripping cam, and the lower end of the tripping cam is provided with a poking block corresponding to the poking rod. The tripping mechanism is accurate and reliable in action and cannot generate misoperation.

Description

technical field [0001] The invention relates to a leakage protection socket, in particular to a mechanical tripping mechanism for the leakage protection socket. Background technique [0002] The leakage protection socket has the protection function of automatically cutting off the circuit when the leakage overload occurs in the circuit, and this function is realized by the electromagnetic release in the leakage protection socket. In order to prevent the situation that the circuit cannot be cut off when the electromagnetic tripper fails, today's leakage protection socket is also equipped with a special manual mechanical tripping mechanism. This manual mechanical tripping mechanism can be forced by hand. Cut off the circuit. At present, the manual mechanical tripping mechanism adopts a button-type structure. When the button is pressed, the circuit is connected, and when the button is popped up, the circuit is cut off. It is very easy to be touched by foreign objects and caus...

Problems solved by technology

At present, the manual mechanical tripping mechanism adopts a button-type structure. When the button is pressed, the circuit is connected, and when the button is popped up, the circuit is cut off. It is very easy to be touched by foreign objects and cause misoperation, and the button has a lot of wear during use, resulting in a short service life
