Iron core retaining structure of electromagnetic contactor

摘要

A structure for reducing impact force due to the collision of a movable iron core (4) against a fixed iron core (3), especially, impact force exerted against a bottom plate of a lower casing (2) where electromagnetic contactor mounting portions are provided. A back portion of the fixed iron core (3) is put on the bottom plate of the lower casing (2) through a convex leaf spring (14) which has opposite end portions bent at right angles to form lower pressure-receiving surfaces (14a) and side pressure-receiving surfaces (14b) so that the lower pressure-receiving surfaces (14a) and the side pressure-receiving surfaces (14b) are brought into contact with the bottom plate of the lower casing (2) and with side walls of the lower casing (2), respectively.
