Abstract
A switch linkage mechanism includes a self-holding solenoid, at least a linkage shaft, at least a twist bar and at least a copper strip set. When the twist bar is at a circuit-closed position, the copper strip set is electrically connected to the high-current circuit breaker. When a self-holding solenoid is activated to pull up a central axle of the self-holding solenoid, the central axle pulls a joint of the linkage shaft and the central axle, and then it pushes the twist bar to be rotated to an circuit-opened position, so that the twist bar stretches out the copper strip set to cause the switch linkage mechanism to be electrically disconnected from the large-current circuit breaker.
Claims10
A switch linkage mechanism, comprising:
- a self-holding solenoid having a central axle capable of protruding or shrinking;
- at least a linkage shaft having one end connected with the central axle;
- at least a twist bar having a central axis and connected with the other end of the linkage shaft, wherein the twist bar is rotated by driving the linkage shaft;
- and
- at least a copper strip set contacted with one end of the twist bar, wherein the copper strip set is stretched by the twist bar to generate deformation.
A large current breaker switch, comprising:
- a self-holding solenoid having a central axle capable of protruding or shrinking;
- at least a linkage shaft having one end connected with the central axle;
- at least a twist bar having a central axis and connected with the other end of the linkage shaft, wherein the twist bar is rotated by driving the linkage shaft;
- at least a copper strip set contacted with one end of the twist bar, wherein the copper strip set is stretched by the twist bar to generate deformation;
- and
- a housing for containing the self-holding solenoid, the linkage shaft, the twist bar and the copper strip set.
