Adopt technique scheme, the annular boss of setting, makes tripping not need and lever contact, the contact area of tripping and annular boss is less than the area of tripping, and the contact-making surface between tripping and annular boss is little, weares and teares little, thus make the movement velocity of tripping fast, circuit breaker highly sensitive.
Further setting of the present utility model: described annular boss and the second axle body are coaxially arranged, annular boss and the second axle body, lever are one-body molded.
Adopt above-mentioned further setting, make the processing of lever, the second axle body, annular boss convenient; And this annular boss set-up mode, can strengthen the intensity of lever, extends its useful life.
Setting further more of the present utility model: the upper end of described lever is provided with the first location notch, is provided with the second location notch in shell, conflicts with the bottom of the first location notch, the bottom of the second location notch respectively in the two ends of the second back-moving spring.
Adopt and above-mentionedly to arrange further again, second back-moving spring is arranged between the upper end of lever and shell, the arm of force produced when lever rotates around the first axle body due to lever upper end is the longest, therefore the restoring force of the second back-moving spring can be made maximum, thus making circuit breaker energy quick acting switching-off, service behaviour is better.
Further setting more of the present utility model: be also provided with the retaining convex rib for preventing the second back-moving spring from departing from the first location notch in the first described location notch, retaining convex rib extends in the second back-moving spring.
Adopt and above-mentionedly further to arrange again, can prevent the second back-moving spring from departing from the first location notch well, thus ensure that the reseting performance of lever is more reliable.
Further setting more of the present utility model: on snap close, corresponding the first axle body receptacle location is provided with positioning boss, the 3rd described back-moving spring winding is on positioning boss, lever is provided with the first draw-in groove, snap close is provided with the second draw-in groove, and the 3rd back-moving spring two ends are stuck in the first draw-in groove, the second draw-in groove.
Adopt and above-mentionedly further to arrange again, make the easier for installation of the 3rd back-moving spring, reseting performance is good.
