きな力で確実に開離させるものである。 When the coil 1 is excited, the attraction piece 23 of the armature 9 is attracted to the attraction surface 8 of the iron core 3. Then, the armature 9 rotates clockwise about the pivot 22, and the drive piece 26 of the armature 9 pushes the movable spring 13 upward. The movable contact 11 is therefore closed to the fixed contact 12. Then, when the excitation of the coil 1 is cut off, the armature 9 returns to its original position due to the restoring force of the spring 10, and the drive piece 26 of the armature 9 also separates from the movable spring 13. The movable spring 13 is a driving piece 26
When the movable spring 13 itself is no longer pressed and driven, the movable spring 13 itself returns to the position shown in FIG. 5, and both contacts 11 and 12 are separated.
At this time, the movable spring 13 also returns immediately, so
The claw piece 14 of the armature 9 does not act on the movable spring.
Next, when contact welding occurs, both contacts 11 and 12 are forcibly separated by the following operation.
That is, since the claw piece 14 of the armature 9 is located above the movable spring 13, when the armature 9 returns due to the return force of the spring 10, the claw piece 14 also moves in the return direction at the same time. The claw piece 14 applies an impact to the upper surface of the movable spring 13 and hooks it, and the movable spring 13
is forcibly returned to open both contacts 11 and 12. At this time, since a gap H is provided between the movable spring 13 and the claw piece 14, the inertia increases by the amount of this gap H, causing the claw piece 14 to move between the movable spring 13 and the claw piece 14.
The contact points 11 and 12 are reliably separated by a larger force.

As described above, in the present invention, when the movable contact and the fixed contact are welded and the coil is de-energized, the claw piece is integrated into the armature and drives the movable spring so as to catch on the movable spring and pull the movable contact away from the fixed contact. Since the two contacts are welded together, the claws can apply an impact to the movable spring as the armature rotates when the coil is not energized, thus forcing the welded contacts to It can be opened to Moreover, the welded contacts are forcibly opened when the coil is not energized, and the force for forcing the contacts to open is determined by the spring force of the spring that returns the armature, so if the spring force of the spring is managed. This has the effect of suppressing variations in forced separation force to a small level.
