Abstract
A ball joint assembly for interconnecting rigid conduits or ducts including spherical ball and socket elements in turn mounted in a housing for universal adjustment. The housing includes spherical segment support surfaces for engaging exterior spherical surfaces defined on the socket element to insure the range of adjustment. A spring member provides electrical continuity between the ball and socket elements comprising a bowed wire of an oblong configuration having an end attached to the ball element and resilient bows engaging the socket and ball elements such that as the elements are angularly displaced, the spring maintains a relatively constant spring load.
