Document Type and Number:
WIPO Patent Application WO/2012/007802
Kind Code:
A1
Abstract:
Provided is a contact apparatus wherein a higher contact pressure can be attained, while the size thereof is inhibited from becoming larger. The contact apparatus is provided with a case (31); anchored terminals (33) comprising anchored contacts (32) housed within the case (31); a movable contact piece (35) comprising movable contacts (34) that make/break contact with the anchored contacts (32); a movable shaft (5) comprising a yoke contact section (52) that is arranged between the upper face of the movable contact piece (35) and the inner face of the case (31), and that regulates the movement of the movable contact piece (35) in the direction of the anchored contacts (32), and also comprising a shaft section (51) connected to the yoke contact section (52); a yoke plate (6) that comes in contact with the underside of the movable contact piece (35), and is opposed to the yoke contact section (52) with the movable contact piece (35) interposed therebetween; a contact pressure spring (36) that applies force to the movable contact piece (35) in the direction of the anchored contacts (32); and an electromagnet block (2) that drives the movable shaft (5) such that the movable contacts (34) make/break contact with the anchored contacts (32). The yoke contact section (52) is configured to have a volume greater than that of the yoke plate (6).
