Dead cable end
First Claim
1. A dead cable end comprising:
- a housing having a housing interior and a housing mouth;
at least two collets, each collet having;
a conical exterior;
a lengthwise collet gap; and
a collet cable passage for allowing a cable to pass through the collets freely when the collets are in a relaxed state;
collet receptacles, one of the collet receptacles cooperating with a respective one of the at least two collets, each collet receptacle having a conical cavity for cooperation with the conical exteriors of the collets, the collets and corresponding collet receptacles sequentially residing in the housing interior; and
a collet retainer including a retainer cable passage for allowing the cable to pass through the collet retainer and configured to connect to the housing mouth for retaining the collet receptacles and the collets in compression in the housing for advancing each collet into the respective collet receptacle to urge the collets to a compressed state to squeeze the cable residing in the collet cable passages to resist removing the cable from the dead cable end.

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.

17. A dead cable end comprising:
-
a housing having a housing interior opening to a housing mouth; a retainer including a retainer cable passage for allowing a cable to pass through the retainer and into the housing interior, the retainer connectable to the housing mouth; a first collet having;
a conical exterior;
a lengthwise collet gap;
a collet cable passage for allowing the cable to pass through the collets freely when the collets are in a relaxed state; and
a collet small end facing the retainer in an assembled dead cable end comprising;a first collet receptacle cooperating with the first collet, the first collet receptacle having a conical cavity for cooperation with the conical exterior of the first collet; a multiplicity of additional collets and additional collet receptacles residing serially between the first collet and the first collet receptacle and the retainer with the collet small ends of the additional collets facing away from the retainer; a spring residing serially with the first collet and the first collet receptacle opposite the additional collets and collet receptacles, wherein the collets and collet receptacles reside serially in compression in the housing between the spring and the retainer for advancing each collet into the respective collet receptacle to urge the collets to a compressed state to squeeze the cable residing in the collet cable passages to resist removing the cable from the dead cable end.

18. A dead cable end comprising:
-
a housing having a housing interior opening to a housing mouth; a retainer including a retainer cable passage for allowing a cable to pass through the retainer and into the housing interior, the retainer connectable to the housing mouth; a first collet having;
a conical exterior;
a lengthwise collet gap; and
a collet cable passage to allow the cable to pass through the first collet freely when the first collet is in a relaxed state, the collet cable passage having rounded ends for preventing damage to the cable, a collet small end of the first collet facing the retainer in an assembled dead cable end;a first collet receptacle cooperating with the first collet, the first collet receptacle having a conical cavity for cooperation with the conical exterior of the first collet; at least one additional collet and at least one additional collet receptacle residing serially between the first collet and the first collet receptacle and the retainer with the collet small end of the at least one additional collet facing away from the retainer; a spring residing serially with the first collet and the first collet receptacle opposite the retainer, wherein the collets and collet receptacles reside serially in compression in the housing between the spring and the retainer for advancing each collet into the respective collet receptical to urge the collets to a compressed state to squeeze the cable residing in the collet cable passages to resist removing the cable from the dead cable end.
