Abstract
A flexure-limiting tubular ball and socket universal joint device protectively supports and guides the inner or center cable of a coaxial push-pull cable assembly while providing a seal effective to exclude dirt and moisture in the variously deflected positions of the inner member and its load-connected extension rod fitting. The cable inner member extension rod fitting passes through a support tube and a sliding seal therein, the support tube having at one end a hollow ball-shaped element that snaps into a mating socket element on a socket tube of resilient plastic material. The socket tube with the ball element retained in the socket element is then inserted longitudinally into a receptacle formed in a tubular terminal member on the outer cable. In the fully inserted position, the snug fit between the socket tube forms a seal, not only with the ball element within it but with the surrounding wall of the tubular fitting receptacle; moreover, the universal joint ball element is then permanently retained within the closely collared socket element, and with the socket tube in its fully inserted position being locked in the receptacle, a rugged protective universal joint and seal is formed.
