Document Type and Number:
Japanese Patent JP2015002012
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a circuit breaker capable of preventing conduction failure or fixing between a movable contact and a fixed contact.SOLUTION: A sliding part includes a movable link 50 rotated with a holder member 101 in the same direction, and a fixing pin 109 for regulating the rotation of the holder member 101 by contacting the holder member 101 before a rotation limit of the movable link 50 is reached. At least a portion of force to the rotation direction, acting on the fixing pin 109 during the rotation regulation of the holder member 101 (a holder part 104) by the fixing pin 109 allows the holder member 101 subjected to the rotation regulation to move in such a direction that slides a movable contact 111 on a fixed contact 120. The movable contact 111 is subjected to the rotation regulation by the fixing pin 109 in the middle of the rotation and is moved in a longitudinal direction Y as a sliding direction to slide on the fixed contact 120.
