Claims

[Scope of utility model registration request]

(1) A circuit breaker tripping device having a spring-loaded operating mechanism provided with a latchable ladle and a latch structure for latching the cradle in a loaded position, the latch structure the body has a pair of cooperating rollers and a body tilted and tilted to bias the pair of rollers to roll the pair of rollers in an unlatched position freeing the rollers; A hard-heating drive surface that drives one of the rollers is inserted between the pair of rollers, and in the latched position, the roller can pivot between a latched position and an unlatched position to prevent the roller from shifting. a spline that slides freely in an unlatched position to permit transfer and is prevented from sliding in a latched position to prevent roller transfer; and an edge of the spline in the latched position. a locking stop that engages the edge; and a trip lever that, when tripped, actively acts on the spline to pivot the spline to an unlatched position, the cradle being in the latched position. having a drive surface in contact with the other roller of the pair of rollers, the edge of the spline pivoted into an unlatched position by the tripping lever is released from the fixed stop and the spline slides into place. and wherein the latching structure is caused to unlatched on its own, and the pivoting movement of the spline causes a small movement that weakens the adhesion of the roller to the drive surface. device tripping device.

(2) the fixed drive surface and the drive surface of the cradle form an acute angle, and the spline is latched along the bisector of the angle such that a roller biases the spline toward the latched position; The tripping device according to claim 1, characterized in that the tripping device extends toward the position.

(3) further comprising a cage holding the pair of rollers, for biasing the cage and the spline holding the rollers to a latched position through the spline inserted between the roller and the spring; 3. The tripping device according to claim 2, wherein the cage is provided with a slot.
