DRIVING MECHANISM FOR MOVABLE CONTACT PIECE AND ELECTROMAGNETIC RELAY USING SAME

摘要

The present invention primarily addresses the problem of providing a driving mechanism for a movable contact piece, the driving mechanism having uniform operating characteristics and not causing faulty contact. To this end, the driving mechanism for a movable contact piece 45 comprises: a movable contact piece 45 having a movable contact point 46 and an engaging hole 48; a fixed contact point 42 facing the movable contact point 46 so as to be capable of making contact with or being separated from the movable contact point 46; and a card 35 having an engaging protrusion 38 engaging with the engaging hole 48 of the movable contact piece 45 at a front end portion thereof, and allowing the movable contact point 46 of the movable contact piece 45 to be in contact with or separated from the fixed contact point 42 by reciprocating in the direction toward the fixed contact point 42. In particular, a flange part 49, which protrudes toward the fixed contact point 42 from at least a portion of an opening of the engaging hole 48, is provided.
