Claims

[Claims for Utility Model Registration] (1) An auxiliary contact unit formed separately from the electromagnetic contactor is attached and coupled to the side wall of the main body case of the electromagnetic contactor so as to be operated by the electromagnetic contactor. In the mounting structure for the auxiliary contact unit, a pair of pin holes extend along the side wall toward the auxiliary contact unit, sandwiching a portion of the side wall of the main body case where the auxiliary contact unit is to be mounted. one protrusion having a holding hole or a recess, and the other protrusion having a holding hole or recess, and further providing a positioning hole between both protrusions, and each of the auxiliary contact units has a pin hole. a pair of stop holes communicating with each other, a holding protrusion that fits into the holding hole or recess, and a positioning protrusion that fits into the positioning hole, and the holding protrusion is fitted into the holding hole or recess. Fit together,
After fitting the positioning protrusion into the positioning hole,
An auxiliary contact unit mounting structure for an electromagnetic contactor, characterized in that a U-shaped pin is inserted in communication with the dowel hole and the stopper hole. 4(2) Utility Model Registration The electromagnetic contactor according to claim 1, characterized in that one of the protrusions is a cover attachment protrusion of the main body case, and the other protrusion is a pedestal of the main body case. (3) Utility model registration In the structure described in claim 1 or 2, the U-shaped pin has elasticity such that both legs of the U-shape expand or narrow relative to each other. A mounting structure for an auxiliary contactor unit of an electromagnetic contactor.
