摘要
Terminals for a vacuum circuit breaker include: a first terminal (300) having a plurality of supporting rings, a plurality of finger contactors (320), and ring-shaped springs installed to contact an outer circumferential surface of the finger contactors so as to provide an elastic force to the finger contactors toward the center; a second terminal (500) having an outer diameter larger than an inner diameter of the first terminal formed by an inner circumferential surface of the finger contactors of the first terminal, and configured by a bushing-type electric conductor; and an insulation guide member (510) detachably fixed to a leading end of the second terminal such that an electric insulating property of the second terminal increases when the first and second terminals are disconnected from each other, having an electric insulating property, and tapered so as to have a decreased outer diameter as a distance from the second terminal becomes long.
