Abstract

A cable assembly including a collar and a cable. The collar includes a first opening, a second opening and a third opening, each of which extends through the collar along a longitudinal dimension of the collar. The cable includes a looped end and a first cable segment extending through the first opening, a second cable segment extending through the second opening, a third cable segment extending into the third opening, and a fourth cable segment forming a loop between the first and second cable segments. The collar is crimped or swaged to the cable and is securely engaged with the first, second and third segments of the cable.

Claims

1. A method of forming a looped cable from a cable and a collar, comprising:

positioning a first segment of the cable in a first opening of the collar;

positioning a second segment of the cable in a second opening of the collar;

positioning a third segment of the cable in a third opening of the collar;

forming a cable turn between the second and third segments of the cable;

forming a loop with a fourth segment of the cable; and

deforming the collar to a deformed state which engages the first, second and third segments of the cable, thereby substantially preventing movement of the first, second and third segments of the cable relative to the collar and securing the cable turn in a fixed orientation;

wherein with the collar deformed, the cable defines a path sequentially comprising the first segment, the fourth segment, the second segment, the cable turn, and the third segment.

2. The method of claim 1, wherein the deforming the collar includes at least one of crimping and swaging the collar.

3. The method of claim 1, wherein the cable includes a wire rope and an outer coating, the method further comprising removing the coating from the second and third segments of the cable prior to the deforming, while retaining the coating on the first and fourth segments.

4. The method of claim 3, further comprising removing a plurality of wire groups from the third segment of the cable prior to the deforming.

21. The method of claim 1, wherein the path extends through the first opening in a first direction, extends through the second opening in a second direction different from the first direction, and extends into the third opening in a third direction different from the second direction.

22. The method of claim 21, wherein the third direction is opposite the second direction.

5. A cable assembly, comprising:

a collar including a first opening, a second opening and a third opening, wherein each of the openings extends through the collar along a longitudinal dimension of the collar; and

a cable comprising a looped end including a first cable segment extending through the first opening, a second cable segment extending through the second opening, a third cable segment extending into the third opening, and a fourth cable segment forming a loop between the first and second cable segments;

wherein the cable comprises a wire rope and an outer coating, the first and fourth cable segments include the wire rope and the outer coating, and the second and third cable segments do not include the outer coating; and

wherein the collar is crimped or swaged to the cable and is securely engaged with the first, second and third cable segments.

6. The cable assembly of claim 5, wherein the wire rope includes a central core and a plurality of wire groups positioned about the central core;

and

wherein the second cable segment includes the central core and the plurality of wire groups, and wherein the third cable segment includes at least the central core.

7. The cable assembly of claim 6, wherein the third cable segment further includes the plurality of wire groups and wherein the collar is directly engaged with the outer coating of the first cable segment and the wire groups of the second and third cable segments.

8. The cable assembly of claim 6, wherein the third cable segment does not include the plurality of wire groups, and wherein the collar is directly engaged with the outer coating of the first cable segment, the wire groups of the second cable segment, and the central core of the third cable segment.

9. The cable assembly of claim 6, wherein the central core comprises a solid core consisting essentially of a single wire having an outer diameter corresponding to an outer diameter of each of the wire groups.

10. The cable assembly of claim 5, wherein each of the openings extends in a direction substantially parallel to a longitudinal axis of the collar.

11. The cable assembly of claim 5, wherein the first opening is connected to and in transverse communication with the second opening.

12. The cable assembly of claim 11, wherein the third opening is not connected to or in transverse communication with either the first opening or the second opening.

13. The cable assembly of claim 5, wherein the second cable segment consists essentially of the wire rope, and the third cable segment consists essentially of the central core.

23. The cable assembly of claim 5, wherein the second cable segment is positioned between the third and fourth cable segments, wherein the cable further comprises a cable turn connecting the second and third cable segments, wherein a path comprising the second and third cable seconds changes directions at the elbow.

14. A method, comprising:

providing a collar including a first portion defining a first opening having a first inner diameter, a second portion defining a second opening having a second inner diameter, and a third portion defining a third opening having a third inner diameter, the collar comprising a single-piece monolithic structure defining the first, second, and third portions;

providing a cable including a first cable segment having a first outer diameter corresponding to the first inner diameter of the first opening, a second cable segment having a second outer diameter corresponding to the second inner diameter of the second opening, a third cable segment having a third outer diameter corresponding to the third inner diameter of the third opening, and a fourth cable segment connecting the first and second cable segments;

positioning the cable relative to the collar, comprising;

positioning the first cable segment in the first opening;

forming a loop with the fourth cable segment;

positioning the second cable segment in the second opening; and

positioning the third cable segment in the third opening;

wherein with the cable positioned relative to the collar, the cable defines a path that sequentially extends through the first opening in a first direction, through the second opening in a second direction different from the first direction, and into the third opening in a third direction different from the second direction; and

deforming the collar such that the first portion securely engages the first cable segment, the second portion securely engages the second cable segment, and the third portion securely engages the third cable segment.

15. The method of claim 14, wherein the providing the cable includes providing a coated cable including wire rope and an outer coating surrounding the wire rope, the wire rope including a central core and a plurality of wire groups positioned about the central core, and wherein the coated cable has the first outer diameter.

16. The method of claim 15, wherein the providing the cable further comprises removing the outer coating from the second and third cable segments, and wherein the wire rope has the second outer diameter.

17. The method of claim 16, wherein the second outer diameter is equal to the third outer diameter.

18. The method of claim 16, wherein the providing the cable further comprises removing the wire groups from the third cable segment, and wherein the central core has the third outer diameter.

19. The method of claim 14, wherein the first, second and third openings in the collar extend along a direction substantially parallel to a longitudinal axis of the collar.

20. The method of claim 19, wherein the first and third directions are opposite the second direction.
