ABSTRACT:
A dead cable end distributes holding force over a length of a cable end to reduce or eliminate damage to cables. The dead cable end includes a housing containing a plurality of collets each residing in a collet receptacle. Each collet includes a conical exterior and a lengthwise collet gap, and each collet receptacle includes a conical interior. The collets and collet receptacle are held inside the housing by a screw-in retaining nut, and the collet and collet receptacle pairs are compressed between the retaining nut and a spring inside the housing. The cable end resides inside the collets, and axial compressive forces on each collet and collet receptacle pair cause each collet to compress radially and hold the cable end. Anti-rotation pins are inserted through the housing into slots in the collet receptacle next to the screw-in retainer to prevent internal rotation during tightening.
