Male coupler end for a rotary steering cable

Abstract

A male coupler end fitting assembly in combination with a flexible conduit is disclosed. The male coupler includes a substantially cylindrical body portion having a male adaptor end and a conduit attachment end disposed on opposing ends of the cylindrical body portion. The male adaptor end has a chamfered surface terminating in a protruding disc shaped end face of a constant uniform diameter, and a transition bevel of a constant uniform diameter circumscribing the male coupler. A relief surface is formed which circumscribes the male coupler, the relief surface being disposed adjacent the transition bevel and perpendicular to ta longitudinal axis. An end face wall circumscribes the male coupler and is disposed adjacent the conduit attachment end and perpendicular to the longitudinal axis. The end face wall has a defined width extending from an outer circumference of the conduit attachment end to a smaller inner circumference, the outer circumference of the conduit attachment end substantially corresponding to the outer circumference of the transition bevel, so as to define a groove between the relief surface and the end face wall. The groove is of a constant diameter and meets with each of the relief surface and the end face wall at substantially a 90 degree angle.
