GROUND FAULT CIRCUIT INTERRUPTER

摘要

A ground fault circuit interrupter includes a reset key, a reset mechanism, a conductive assembly configured to connect a power supply input side to a load side, a leakage signal detection circuit, and an electromagnetic tripping mechanism. The reset mechanism comprises a reset support and a support return mechanism. The reset support comprises a reset bracket and a support reset spring. The support return mechanism comprises a reset pole, a reset key spring, a compression spring, a reset block, a compression spring container, a reset slider, and a contact conductive part. The contact conductive part is disposed at a lower end of the reset slider and is configured to align with a position of a switch contact on a first PCB board. A state of contact or separation between the contact conductive part and the switch contact is configured to control an on-off state of the conductive assembly.

1. A ground fault circuit interrupter, comprising:
a reset key; a reset mechanism; a conductive assembly configured to connect a power supply input side to a load side; a leakage signal detection circuit; and an electromagnetic tripping mechanism configured to be controlled by the leakage signal detection circuit, wherein:
the reset mechanism comprises a reset support and a support return mechanism;the reset support comprises a reset bracket and a support reset spring disposed in the reset bracket;the support return mechanism comprises a reset pole, a reset key spring, a compression spring, a reset block, a compression spring container, a reset slider, and a contact conductive part;the reset support has a first position in a reset state and a second position in a tripping state;the support return mechanism is engaged with the reset support such that the reset support is biased to slide from the first position to the second position;the contact conductive part is disposed at a lower end of the reset slider and is configured to align with a position of a switch contact on a first PCB board; anda state of contact or separation between the contact conductive part and the switch contact is configured to control an on-off state of the conductive assembly.
