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 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 compressive force on each collet and collet receptacle pair causes each collet to compress radially and hold the cable end. The holding force is thereby distributed over the length of each collet and over the plurality of collet and receptacle pairs to avoid damage to the cable.
