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.

First claim

What is claimed is:

1. A cable assembly for a work machine, the cable assembly comprising:
a cable including:
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, wherein the shield layer is folded back over a fold length, and the fold length is covered with two layers of the shield layer;

a collet including an inner sleeve and an outer sleeve extending over a portion of the inner sleeve at an end of the collet, wherein the 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.

2. The cable assembly of claim 1 , wherein the cable includes a protective layer over the shield layer, and a portion of the protective layer is between the two shield layers of the fold length.

3. The cable assembly of claim 1 , wherein the inner sleeve includes a bend.

4. The cable assembly of claim 1 , wherein the inner sleeve includes a bend that is at least a ninety-degree bend or sharper bend.

5. The cable assembly of claim 1 , wherein the inner sleeve includes a stop having a stop edge, and the fold length extends under the outer sleeve to the stop edge.

6. The cable assembly of claim 5 , wherein the inner sleeve has a constant inner diameter and an outer diameter that increases from the end of the collet to the stop edge.

7. The cable assembly of claim 5 , wherein the stop includes a ridge positioned between the stop and another end of the collet, wherein the ridge rings the inner sleeve and an end of the outer sleeve is crimped over the ridge of the inner sleeve.

8. The cable assembly of claim 1 , wherein the outer sleeve of the collet is compressed onto the fold length and the inner sleeve.

9. The cable assembly of claim 1 , wherein the collet includes a mounting collar at another end of the collet and the second length of the cable extends beyond the mounting collar of the collet.

10. The cable assembly of claim 1 , wherein the core of the cable has a diameter greater than or equal to ten millimeters (10 mm).

11. The cable assembly of claim 1 , wherein the shield layer of the cable includes braided metal.
