IPC: H01H71/10
Filed: 1990-11-26
Abstract: PURPOSE:To make high speed separation of contact points possible at the time of breaking by arranging so that the torque in the direction of giving contact force with the defection in the pole opening direction is made to have a characteristic in which the torque, when resisting the contact force imparting means, once increases and then decreases.

The contact force imparting means 40 is arranged to have the characteristic in which, once it springs back, the torque in the direction of giving the contact force with the deflection in the point opening direction once increases and then decreases. Because the contact force imparting means 40 uses a spring to give a constant pressure between the contact points 5 and 10, the decreasing rate of the length of the line of action between the rotation center of the repulsive contact point base 34 and the spring 40 is greater in comparison to the increasing rate of the force of the spring force due to the rotation of the repulsing point 10, reaction torque decreases and the repulsive contact point base 34 can rotate at a high speed. this increases the separation speed of the repulsing point at the time of breaking and provides a breaker for wiring excellent in breaking characteristic.
