[Scope of utility model registration request] It is installed between the upper ends of adjacent magnetic contactors and the adjacent magnetic contactors to connect both magnetic contactors, and when the contact of one magnetic contactor is turned on, the contact of the other magnetic contactor is connected. An interlock device for a magnetic contactor comprising an interlock body having a locking means for interlocking adjacent magnetic contactors so as to prevent the contacts from being driven to the on side,
A movable body that can move up and down in conjunction with the movable core that is attracted to the fixed core of the electromagnetic contactor, and a pair of L-shaped bodies with opposing tips formed on the upper part of the movable body that protrudes from the top surface of the electromagnetic contactor. an engaging protrusion, and a pair of protrusions integrally protruding from one side of the upper surface of the electromagnetic contactor and having engaging recesses facing each other at a distance shorter than the dimension between the pair of engaging protrusions; The electromagnetic contactor includes an engagement step portion having an inclined surface that descends on the other side of the upper surface of the electromagnetic contactor, and an engagement groove formed on the other side of the electromagnetic contactor. The above-mentioned locking means is provided in each contactor and is inserted between and engaged between the engagement protrusions of the above-mentioned movable body of an adjacent electromagnetic contactor when the interlock body is slid from the other side of the upper surface of the electromagnetic contactor. an engaging portion formed into a vertically movable member and having a substantially T-shaped tip; an engaging projection portion having a substantially T-shaped tip that is inserted between the protrusions and engaged; and an inclined portion of the stepped portion. The distal end is inserted from the outside into the groove and engages with the engagement step formed on the inside of the engagement portion by going over the surface and engaging with the inside of the step, and is formed on the outside of the engagement portion. L-shaped hook portions are formed symmetrically on the lower surface of the interlock body,
Both of the symmetrically formed engagement steps are formed into elastic lock pieces, and an operating part is formed approximately in the center of the lock pieces to protrude outward from the side surface of the interlock body. An electromagnetic contactor interlock device featuring:
