Ground fault circuit interrupter and reset mechanism thereof

Abstract

The invention discloses a ground fault circuit interrupter with a simple and concise structure and convenience in assembling, and a reset mechanism thereof. The reset mechanism comprises a reset button, an electromagnet and a reset mounting bracket; a rotational lifting block is movably arranged on the reset mounting bracket; lifting parts are arranged on the two sides of one end of the rotational lifting block respectively; a clamping hook is arranged at the other end of the rotational lifting block; a lifting block spring is arranged on one side of each lifting part of the rotational lifting block; the reset mounting bracket is provided with a limiting block matched with the rotational lifting block; a sliding seesaw plate is also movably arranged in the reset mounting bracket; a seesaw plate bending part is arranged on the tail part of the sliding seesaw plate; a seesaw plate bayonet is formed in the end part of the seesaw plate bending part; an iron core clamping groove matched with the seesaw plate bayonet is formed in the iron core of the electromagnet; the seesaw plate bayonet is clamped in an iron core clamping groove of the iron core; and a reset rod matched with one side of the clamping hook of the rotational lifting block is arranged at the bottom of the reset button. The ground fault circuit interrupter equipped with the reset mechanism has wide applications.

Description

technical field [0001] The invention relates to a power socket, in particular to a ground fault leakage protector (GFCI for short in English). Background technique [0002] As we all know, the reset mechanism in the current ground fault leakage protector, namely Ground Fault Circuit Interrupter (GFCI for short), is relatively complicated, and its structure usually includes: a lock mounting bracket installed on the main circuit board, and the lock mounting bracket is provided with a The lifting chute surrounded by four columns, the lifting slider is movable in the lifting chute, the lifting slider is provided with a reset rod hole that penetrates up and down, and an upper reset spring hole located on the upper edge of the reset rod hole and a reset spring hole located on the reset rod hole. The lower return spring hole of the lower edge of the rod hole, the top of the lower return spring is inserted into the lower return spring hole, the bottom of the lower return spring is a...

[0002] As we all know, the reset mechanism in the current ground fault leakage protector, namely Ground Fault Circuit Interrupter (GFCI for short), is relatively complicated, and its structure usually includes: a lock mounting bracket installed on the main circuit board, and the lock mounting bracket is provided with a The lifting chute surrounded by four columns, the lifting slider is movable in the lifting chute, the lifting slider is provided with a reset rod hole that penetrates up and down, and an upper reset spring hole located on the upper edge of the reset rod hole and a reset spring hole located on the reset rod hole. The lower return spring hole of the lower edge of the rod hole, the top of the lower return spring is inserted into the lower return spring hole, the bottom of the lower return spring is against the lock mounting bracket, and the bottom of the upper return spring is inserted In the hole of the upper return spring, the top of the upper return spring leans against the middle frame of the installation, the front part of the lifting slider is provided with a pressing part matched with the micro switch, and the left and right wings of the lifting slider are respectively provided with a lifting part , facing the reset rod hole on the lifting slider, there is a lock socket through the front and back above the pressing part, and a lock is slid in the lock socket, and the tail of the lock is movable and set on the electromagnet. On the annular groove at the end of the iron core, there is an oblong hole corresponding to the hole of the reset rod on the lock

In the actual production process, the assembly is relatively difficult, which greatly affects the assembly efficiency and increases the production cost
