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.

摘要： An electromagnetic contactor coupling device, in which electromagnetic contactors are put side by side with an interlock unit sandwiched therebetween for preventing the electromagnetic contactors from simultaneously turning on, and are integrally coupled to each other by a coupler. The device is arranged to have abutment portions wider at its rear end than at its front end so that, in order to prevent displacement of the interlock unit due to vibrations or the like, force for sandwiching the interlock unit is exerted on the interlock unit as the coupler is inserted between the electromagnetic contactors.

摘要： An electromagnetic contactor includes an engaging portion formed on a side surface of its body and disposed below a coil terminal. An attachment is releasably attached to the body of the electromagnetic contactor. The attachment includes a casing containing an electric component, the casing having a resilient projection formed on a side surface thereof. The resilient projection is resiliently engageable releasably with the engaging portion. The attachment has a plate-like connecting element projecting outwardly from the casing. The connecting element is connectable with the coil terminal when the attachment casing is attached to the body of the electromagnetic contactor.

摘要： An electromagnet device for an electromagnetic contactor is formed of a frame with an opening, a movable-contact supporter slidably disposed in the frame, a movable contact supported by the movable-contact supporter, a movable core connected to the movable-contact supporter, and a stationary core for attracting the movable core. The stationary core includes a base plate for closing the opening of the frame, at least one columnar arm core fixed to the base plate to extend therefrom, and at least one pole piece fixed to the arm core at a side opposite to the base plate. The pole piece provides attracting force to the movable core when the stationary core is energized. In the electromagnetic device, a device for partly interrupting a magnetic path of the stationary core is formed. The interrupting device reduces remanent flux in the stationary core when the stationary core is deenergized.
