Abstract

Abstract A connector for forming a fluid tight, electrically conductive joint between two juxtaposed, fluid-colled stator bar ends or between a bar end and a connection ring of a dynamoelectric machine which may be misaligned during stator assembly. The connector is comprised of two movable and rotatable fittings with a sleeve member therebetween which are so formed as to correct slight bar or connection ring misalignment. The sleeve member has an interior brazing surface at each end defined by a counterbored hole. In one embodiment, the sleeve is bent so that the centerlines of the counterbored holes are noncoincident. In other embodiments, the sleeve is straight but the counterbored holes are formed so that the centerlines of one or both counterbored holes do not coincide with the centerline of the sleeve.
