Abstract

The invention discloses a tripping structure of a molded case circuit breaker. The problems are solved that a molded case circuit breaker tripping structure is complex in structure, and manufacturingand assembling steps are tedious, so production cost is high and price is high. The structure comprises a bottom plate, a first binding post is fixed to one side of the bottom of the bottom plate. Thetop end of the first binding post is provided with a first metal plate. The top end of the first metal plate is connected with a first supporting plate; a second switch is mounted in the middle of the first supporting plate; a fourth binding post is fixed on the other side of the bottom of the bottom plate; the top end of the fourth binding post is connected with a fourth metal plate; a first guide column is mounted on one side of the top of the first supporting plate; the other side of the top end of the first supporting plate is connected with a second guide column, the outer side of the first guide column is sleeved with a first contact piece, the middle of the first contact piece is provided with a lead screw, the top end of the lead screw is connected with a motor, and the top end ofthe motor is provided with a first switch. The tripping structure has a simple structure, and the steps of manufacturing and assembling are not complicated, and the production cost is reduced, thereby reducing the sales price.

Description

technical field [0001] The invention belongs to the technical field of tripping structures, and in particular relates to a tripping structure of a molded case circuit breaker. Background technique [0002] The tripping structure is an important part of the operating system to promote the automatic tripping of the switch. When the circuit breaker is in the closing process and in the closing position, the tripping mechanism acts like a fulcrum of force. When the circuit breaker trips automatically, the tripping The buckle mechanism is manipulated by the trip device, and the fulcrum is released to make the circuit breaker enter the free opening state. Generally speaking, the lever and spring mechanism in the switch are supported by the trip device. Once the trip device operates, the switch The lever and spring mechanism in the mouse will reset freely, that is, the switch trips, and the release device here is equivalent to the pin for hanging the bait in the mousetrap.
