Abstract

A cable assembly for a work machine, includes a cable and a collet. The cable includes an electrically conductive core, an insulating layer covering the core; an electrically conductive shield layer covering the insulating layer over a first length of the cable, and the insulating layer is exposed over a second length of the cable. The shield layer is folded back over a fold length, and the fold length includes two layers of the shield layer. The collet includes an inner sleeve and an outer sleeve extending over a portion of the inner sleeve at an end of the collet. The two shield layers of the fold length are arranged over the inner sleeve and under the outer sleeve, the insulating layer is arranged under the inner sleeve, and the second length of the cable extends through the inner sleeve.

Claims (16)

1 . A collet for a cable assembly of a work machine, the collet comprising:

an inner sleeve having a tube shape with a bend, the inner sleeve including:

a first sleeve portion at an end of the collet and including a constant inner diameter and an outer diameter that increases from an end of the inner sleeve; and

a second sleeve portion including a constant outer diameter; and

an outer sleeve extending over the first sleeve portion of the inner sleeve.

2 . The collet of claim 1 ,

wherein the first sleeve portion of the inner sleeve includes a ridge that rings the inner sleeve and the outer diameter of the first portion of the inner sleeve increases from the end of the inner sleeve to the ridge of the inner sleeve; and

wherein an end of the outer sleeve is crimped over the ridge of the inner sleeve.

3 . The collet of claim 1 , wherein the bend of the inner sleeve is at least a ninety-degree bend or sharper bend.

4 . The collet of claim 1 , wherein an inner surface of the first portion of the inner sleeve includes one or more barbs.

5 . The collet of claim 1 , wherein the inner sleeve includes a stop having a stop edge.

6 . The collet of claim 5 , wherein the outer diameter increases from the end of the collet to the stop edge.

7 . The collet of claim 1 , including a mounting collar at another end of the collet, wherein an opening of the mounting collar has the inner diameter.

8 . The collet of claim 1 , wherein the inner diameter is greater than or equal to ten millimeters (10 mm).

9 . The collet of claim 1 , including a first straight section and a second straight section, and the bend of the inner sleeve is between the first straight section and the second straight section, and wherein the first straight section has a different length than the second straight section.

10 . The collet of claim 1 , wherein the inner sleeve includes a notched ring on an outer surface of the inner sleeve.
