Patent ID: 8373525

Claim:
An electromagnetic contactor, comprising: a stationary core; a coil arranged around the stationary core; a movable holder arranged movably toward the stationary core and having a pair of holder legs respectively provided on a side facing the stationary core; a movable core coupled to one end of the movable holder in proximity to the stationary core for being attracted to the stationary core by an excitation of the coil; and a nonmagnetic structural component arranged on the movable core on the side facing the stationary core, wherein the nonmagnetic structural component is a flat plate with flexural rigidity, and is arranged to be overlaid on a surface of the movable core facing the stationary core, and the nonmagnetic structural component and the movable core are held between a cushioning spring and a coupling pin, the cushioning spring being contained in the movable holder and abutting against a back face of the movable core not facing the stationary core, and the coupling pin being arranged across the nonmagnetic structural component with both ends engaging with the pair of holder legs, respectively, wherein the nonmagnetic structural component includes guides for restricting shifting of the nonmagnetic structural component relative to the holder legs of the movable holder along the surface of the movable core, and wherein each of the guides is formed as a pair of protrusions protruding from an edge of the nonmagnetic structural component to sandwich one of the holder legs between the pair of protrusions, and the pair of protrusions has a clearance with respect to the holder leg facing thereto.
