る電磁接触器。[Scope of Claim for Utility Model Registration] A movable core that is attracted to a fixed core by electromagnetic force generated by a coil and released by a tripping elastic body, having movable contacts and a rotating shaft at both ends, and centered around the rotating shaft. A movable contact inserted into a window of a cross bar that interlocks with the movable iron core, a push spring that applies contact pressure to the movable contact inserted into the window of the cross bar, and a push spring facing the movable contact. A fixed contact having a fixed contact is provided, and the movable contact contacts the fixed contact when the movable iron core is attracted, and the movable contact is separated from the fixed contact when the movable iron core is released. Features of electromagnetic contactor.

Claims

[Scope of utility model registration request]

The movable core is attracted to the fixed core by the electromagnetic force generated by the coil and released by the tripping elastic body, and has movable contacts and a rotating shaft at both ends, and is interlocked with the movable core around the rotating shaft. The movable contact includes a movable contact inserted into a window of the cross bar, a push spring inserted into the window of the cross bar and applying contact pressure to the movable contact, and a fixed contact opposite to the movable contact. An electromagnetic contactor characterized in that the movable contact contacts the fixed contact when the iron core is attracted, and the movable contact is separated from the fixed contact when the movable iron core is released.
