Claims

[Scope of utility model registration request]

A latch whose one end is pivotally connected to a device holding frame attached to the electromagnetic contactor and is rotatably provided in conjunction with the crossbar of the electromagnetic contactor, and the holding frame! The magnetic contactor is rotatably mounted near the tip of the latch, and when the main circuit contact of the electromagnetic contactor is open, the tip flank comes into contact with the tip surface of the latch, and when the main circuit contact is closed, the tip a latch lever whose latch surface engages with the end engagement surface of the latch to restrict return movement of the crossbar;
In a latching device for an electromagnetic contactor including a latch spring that always positions the tip of the clutch lever in the direction of the latch, the latch is latched when the latch and the latch lever are in contact with each other when the main circuit contact is opened. The relief surface at the tip of the lever is formed as a retraction surface that gradually retreats from the rotation locus area of the tip surface of the latch toward the tip from the contact position with the latch, and as the latch rotates, the tip surface of the latch and the latch lever After the engagement with the relief surface of the tip of the latch lever is released, the tip latch surface of the latch lever instantly enters the rotation locus area of the tip surface of the latch with an initial velocity, and the tip surface of the latch lever locks the tip of the latch. A latching device for an electromagnetic contactor characterized by latching engagement with a mating surface.
