Abstract

The invention discloses a switch circuit breaker structure. The switch circuit breaker structure comprises a shell, a hand control mechanism, a connecting rod, a clamping plate, a moving contact arm, a tripping rod, a pawl, a supporting shaft and a push rod, wherein a first rotary shaft and a second rotary shaft are formed on the pawl in an integral injection molding mode, and are arranged on the two sides of the pawl respectively, and the pawl is connected to the clamping plate through the first rotary shaft and the second rotary shaft in a rotatable mode. When the switch circuit breaker structure is assembled, assembly can be accomplished only by using the first rotary shaft and the second rotary shaft to assemble the pawl on the clamping plate, shafts or shaft sleeves are omitted, and installation accuracy of parts is improved; the number of the parts of the switch circuit breaker structure is reduced, and production efficiency, assembling efficiency and quality are improved.

Description

technical field [0001] The invention relates to the field of line protection switches, and more specifically relates to a switch circuit breaker structure. Background technique [0002] Chinese patent document CN1210747C discloses a protective switch device, which includes a hand-operated mechanism, a connecting rod, a splint, a moving contact arm, a trip lever, a pawl, a first support shaft, a support shaft and a push rod, and the support shaft is a The fixed rod, the splint and the trip lever are all in a rotatable state with the support shaft as the rotation axis. The splint, the moving contact arm and the pawl are also rotatably connected to the first support shaft, and the hand control mechanism is connected through the connecting rod. , The pawl is supported and rotatably connected to the pawl, the pawl can be buckled with the trip lever, and the lower end of the moving contact arm is also formed with a fixed contact to form a contact pair. The trip lever moves to sep...
