Claim Text:
1. A cable fitting, comprising: a gland nut including first threads, an axial gland bore, and a first sloped surface along a portion of the axial gland bore; a body including second threads configured to receive the first threads, an axial body bore, and a second sloped surface along a portion of the axial body bore; and a chuck including multiple segments and multiple joints interposed between the multiple segments, the multiple segments and multiple joints joined to create a ring, wherein each of the multiple segments includes a distal end tapered surface and a proximal end tapered surface, a taper angle of each of the proximal end tapered surfaces being greater than 25 degrees and less than or equal to 45 degrees from a central axis of the cable fitting, wherein each joint of the multiple joints includes a strip that folds inwardly along a line parallel to the central axis to reduce an inside diameter of the ring, wherein the gland nut, the body, and the chuck are configured to form an axial pathway for receiving a cable, wherein, the second sloped surface includes a same taper angle as the taper angle of each of the proximal end tapered surfaces such that, when the first threads of the gland nut are advanced onto the second threads of the body, the first sloped surface is configured to apply a first compressive force to the distal end tapered surfaces and the second sloped surface is configured to apply a second compressive force to the proximal end tapered surfaces, and wherein the first and second compressive forces cause inward deformation of the chuck to secure the cable within the axial pathway while maintaining the taper angle of each of the proximal end tapered surfaces.
