Embodiment Construction

[0005] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0006] In the figure, the gimbal 1 and the release iron core 2 are injection molded together. There are round grooves on the sides of the gimbal on the left and right sides of the gimbal for installing the dynamic contact springs. The moving contact piece slot of sheet, then have a reset moving contact piece slot 3 on the other side of the gimbal, for placing the reset moving contact piece. In the middle of the two reset moving contact slots is a circular groove for installing the reset moving contact spring. When the ground fault circuit breaker is in the tripping state, the balance frame is in the tripping position. At this time, the reset movable contact piece on the balance frame contacts the reset static contact pin on the magnetic ring cover, and the reset on the line is completed for the reset. Prepare. When the balance frame is in th...

Abstract

The balancing-stand is injection molded with the tripping iron core together. Slots of movable contact piece in use for placing movable contact pieces are made at two sides. Slot of resetting movable contact piece in use for resetting movable contact pieces is prepared on side face of the other rack body of the balancing-stand. Since the balancing-stand and the tripping winding framework are located at same horizontal, the invention guarantees better contact between moving silver contact and static silver contact so as to realize better conductivity. The tripping winding framework is connected to the balancing-stand directly. Changing slot position of movable contact piece is possible to assemble parts of the balancing-stand easier. Features are: simple structure, clever conception, lowered manufacturing cost, labor intensity and technical difficulties.

Description

Technical field: [0001] The invention relates to a balance frame in a ground fault circuit breaker (GFCI), in particular to a balance frame with a resetting movable contact piece slot. Background technique: [0002] At present, the structure of the balance frame in the known ground fault circuit interrupter (GFCI) generally has a moving contact slot, and a moving contact with a riveted moving contact silver point and a welded conductive strip is placed in the slot, and the back and forth through the balance frame The movement realizes the contact of the dynamic and static silver point and realizes its conductivity. The existing gimbal has the disadvantages that it is difficult to assemble, and the electrical conductivity when the dynamic and static silver contacts are closed may produce adverse effects. Invention content: [0003] The purpose of the present invention is to provide a balancing frame with a resetting movable contact piece slot that can effectively overcome ...
