Title:
MOVEABLE CONTACT PIECE, AND ELECTROMAGNETIC RELAY PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2015/005314
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a moveable contact which consumes little power, and which can be produced with few component parts and assembly steps, and with high productivity. In order to accomplish said purpose, a moveable contact piece (60) is driven by stacking three conductive thin-plate springs (61, 65, 67), of which one end is integrally secured to a moveable contact point terminal (54) while the free end is integrally secured to moveable contact points (56, 57), and by turning a card (40) that engages with the free end, thus bring the moveable contact points (56, 57) into and out of contact with the fixed contact points (52, 53). In particular, an elastic driving tongue piece (64a), which engages with the card (40), is disposed on the free end of the conductive thin-plate spring (61) positioned toward the inner surface, and a pair of elastic returning tongue pieces (67b, 67c), which comes into partial contact with the card (40) in a step for transitioning from a state in which the moveable contact points (56, 57) come into contact with the fixed contact points (52, 53) to a state in which the moveable contact points (56, 57) and the fixed contact points (52, 53) are away from one another, is cut and raised from the free end of the conductive thin-plate spring (67) positioned toward the outer surface.
