<P>PROBLEM TO BE SOLVED: To provide a vacuum circuit breaker terminal minimizing a shock and vibration when a breaker body side terminal and a cradle side terminal are brought into contact with and separated from each other and to provide a vacuum circuit breaker. <P>SOLUTION: The vacuum circuit breaker terminal includes: a first terminal 300 having a plurality of support rings 360, a plurality of finger contactors 320 which are radially arranged at the periphery of the support ring 360 and a ring-like spring 350 which is arranged in contact with an outer peripheral face of the finger contactor 320 so as to energize the finger contactor 320 in a center direction; a second terminal 500 which has an outer diameter larger than an inner diameter of the first terminal 300 formed at an inner peripheral face of the finger contactor 320 of the first terminal 300 and is a bushing-like electric conductor; and a tapered insulating guide member 510 which is installed so as to be attached/detached to/from the second terminal 500 so that electric insulating property of the second terminal 500 is improved when the first terminal 300 and the second terminal 500 are separated, has the electric insulating property, and whose outer diameter becomes smaller as it recedes from the second terminal 500. <P>COPYRIGHT: (C)2012,JPO&INPIT |
