器。The figure is a sectional view of the main part of the iron core included in the electromagnetic contactor according to the present invention. In the figure, 10 is a fixed core, 12 is a movable core, 14 is a spacer, and t is a step. Correction 1984. 4. 5. The scope of claims for utility model registration shall be amended as follows. ◎Claims for Utility Model Registration (1) A diode or the like is connected in parallel with the operating coil,
The operating coil has a flywheel circuit formed when viewed from the operating coil, and the fixed iron core attracts the movable iron core by the magnetic flux of the operating coil excited by direct current, closing the main circuit, and the fixed iron core and the movable iron core are connected. In an electromagnetic contactor in which a non-magnetic spacer is provided on at least one of the armature surfaces to prevent attraction due to residual magnetism of both cores, there is a step on at least one of the armature surfaces of the fixed core and the movable core. An electromagnetic contactor characterized in that the time for contact and fall of a movable core to a fixed core is shortened. (2) Utility Model Registration The electromagnetic contactor according to claim (1), wherein at least one of the fixed core and the movable core is formed by laminating steel plates.

Claims

[Scope of utility model registration request]

(1) The fixed core attracts the movable core by the magnetic flux of the operating coil excited by direct current, closing the main circuit, and at least one of the polarized surfaces of the fixed core and the movable core is affected by the residual magnetism of both cores. In an electromagnetic contactor in which a non-magnetic spacer is provided to prevent adsorption, a step is provided on the armature surface of at least one of the fixed core and the movable core, and the movable core contacts and falls to the fixed core. An electromagnetic contactor characterized in that: is shortened.

(2) Utility Model Registration The electromagnetic contactor according to claim (1), wherein at least one of the fixed core and the movable core is formed by laminating steel plates.
