ABSTRACT:
A method of electrically and hydraulically connecting a conductor bar having a plurality of hollow water-cooled conductors involves compressing the conductor bar and shims of brazing material in a connector clip formed of a pair of mating clip members. Brazing shims (strips and bands) are placed in desired positions, and then the components are heated and hydraulically compressed. The conductor bar and brazing material assembly is sized for a tight fit in one dimension, but oversized in another dimension so that compression results in a desired distribution of the molten brazing material. During compression, the clip members are secured from relative motion, other than displacement toward one another, and air is passed through the hollow conductors to prevent the accumulation of brazing material in the open ends thereof. In addition to the clip members, the connector device includes a water inlet member with a stem that is inserted between and brazed to the clip members after the compression step.
