Abstract

A cable for encasing one or more wires includes at least one wire, cable, or conductor, a tube surrounding the at least one wire, cable, or conductor, and a conductive or textile material surrounding the tube. The cable further includes a jacket surrounding the conductive or textile material, wherein the jacket is formed from at least one synthetic rubber.

a ferrule having first and second ferrule ends, a ferrule opening therethrough, and one or more teeth disposed axially along the ferrule opening, wherein the ferrule is formed from a conductive material and wherein the first ferrule end is disposed over the second fitting end; and

an inner conductive layer;

a jacket surrounding the inner conductive layer, wherein the jacket is formed from at least one synthetic rubber; and

wherein the inner conductive layer and the jacket are disposed between the second fitting end and the first ferrule end and the ferrule is secured around the fitting so that at least one of the one or more teeth pierce the jacket and wherein an EMI/RFI shield is created across the fitting, the ferrule, and the inner conductive layer.

2. The cable connector assembly of claim 1, further comprising a coupling ring secured around the first fitting end, wherein the coupling ring allows attachment of the cable connector assembly to a mating connector, and wherein the coupling ring is formed from a conductive material and contacts the fitting to create an EMI/RFI shield across the coupling ring, the fitting, the ferrule, and the tube.

3. The cable connector assembly of claim 1, wherein the one or more teeth are annular and the fitting includes a plurality of annular ridges disposed on an outer surface of the fitting proximate the second fitting end and wherein the annular ridges are tapered with a deepest portion of each annular ridge being disposed toward the first fitting end.

4. The cable connector assembly of claim 1, further comprising a nonconductive insert having first and second insert ends and an insert opening therethrough, wherein the second insert end is disposed within the first fitting end.

5. The cable connector assembly of claim 4, wherein the insert includes a key structure disposed within the insert opening adjacent the first insert end, and wherein the key structure extends axially past ends of one or more wire contacts disposed within the insert opening and spaced from the first insert end.

6. The cable connector assembly of claim 4, wherein the insert includes a plurality of spaced apart snap legs disposed at the second insert end and the fitting opening defines an annular cavity disposed in a central portion thereof and having first and second annular ledges such that upon insertion of the second insert end into the first fitting end, the snap legs enter the cavity and move outwardly such that interference between the first ledge and first surfaces of the snap legs substantially prevents axial movement of the insert in a first direction and interference between the second ledge and second surfaces of the snap legs substantially prevents axial movement of the insert in a second direction opposite to the first direction.

7. The cable connector assembly of claim 4, wherein the insert includes one or more projections extending outwardly from the insert between the first and second insert ends and the fitting includes a corresponding number of grooves disposed in the first fitting end such that when the insert is disposed within the fitting, the projections are disposed within the grooves to prevent rotational movement of the insert in the fitting.

8. The cable connector assembly of claim 1, wherein the fitting includes an annular shoulder disposed between the first and second fitting ends, a first o-ring disposed on a first side of the annular shoulder, and a second o-ring disposed on a second opposing side of the annular shoulder, and wherein the ferrule is crimped around substantially 360°

thereof so that the first and second o-rings are sandwiched between the fitting and the ferrule to form a seal therebetween.

9. The cable connector assembly of claim 1, wherein the jacket is heat resistant.

10. The cable connector assembly of claim 9, wherein the jacket is formed from an abrasion-proof heat/flame resistant material.

11. The cable connector assembly of claim 10, wherein the inner conductive layer is formed from a metal that provides an EMI/RFI shield.

12. The cable connector assembly of claim 11, wherein the synthetic rubber of the jacket comprises an outer layer and further including a textile layer inside the outer layer and a nitrile inner layer inside the textile layer and outside the inner conductive layer.

13. The cable connector assembly of claim 12, wherein the inner conductive layer includes one or more wires extending therethrough.

14. The cable connector assembly of claim 1, wherein the material forming the jacket is formed of a material having one or more of the following properties:

abrasion-proof or resistant, heat resistant, flame resistant, tear resistant, low temperature flexibility, chemical resistant, and high temperature resistant.

15. The cable connector assembly of claim 1, wherein the synthetic rubber comprises at least one polychloroprene.

16. A cable connector assembly, comprising:

a fitting having first and second fitting ends and a fitting opening therethrough, wherein the fitting is formed from a conductive material;

a coupling ring formed from a conductive material, wherein the coupling ring is secured around the first fitting end;

a ferrule having first and second ferrule ends, a ferrule opening therearough, and a plurality of teeth disposed axially along the ferrule opening, wherein the ferrule is formed from a conductive material and the first ferrule end is disposed over the second fitting end; and

an outer nonconductive layer and an inner conductive layer disposed between the second fitting end and the first ferrule end wherein the outer nonconductive layer surrounds the inner conductive layer;

wherein the outer nonconductive layer is formed from at least one synthetic rubber; and

wherein the ferrule is secured around the fitting so that at least one of the plurality of teeth pierce the outer nonconductive layer and wherein an EMI/RFI shield is created across the coupling ring, the fitting, the ferrule, the outer nonconductive layer, and the inner conductive layer.
