Abstract

A breaker includes a shell (1), a driving wheel (2), a tripping frame (3), a handle (4), a connecting rod (5), a moving contact (6), a first elastic resetting element (8), a second elastic resetting element (9), and a magnetic trip (10); the magnetic trip includes a fixed contact (7); the handle is rotatablely installed in the shell, one end of the connecting rod is connected with the handle, and the other end contacts and cooperates with the driving wheel and the tripping frame; one end of the first elastic resetting element is connected with the shell, and the other end is connected with the driving wheel; one end of the second elastic resetting element is connected with the driving wheel, and the other end is connected with the tripping frame; the driving wheel comprises a driving wheel main body, a first rotation shaft, and a second rotation shaft, the first rotation shaft and the second rotation shaft are disposed at the driving wheel main body, the driving wheel is rotatablely installed in the shell by the first rotation shaft, the tripping frame is rotatablely disposed at the driving wheel by the second rotation shaft, and the moving contact is disposed opposite to the fixed contact; and the moving contact is installed at the driving wheel and is driven to rotate to contact or be separated from the fixed contact when the driving wheel is rotating. The breaker in the invention is simple in structure, convenient for assembly and low in costs.
