    摘要: An electrode of a vacuum circuit breaker includes a support electrode, an auxiliary support electrode of Co soldered to the support electrode, and an electric contact portion composed of a sintered porous body of Co sintered to the auxiliary support electrode and a conductive alloy impregnating the sintered porous body. The auxiliary support electrode has a protrusion formed with a flange at its end portion. The auxiliary support electrode thus prepared acts to provide a barrier to a solder during the soldering operation, to increase the joining width between the electrical contact portion and the electrode, and to prevent the characteristics of that alloy from being degraded by the soldering operation.
