Claims
- 1. An assembly for environmentally protecting a cable connection in which an end of a cable is connected to a connector having a coupling nut, which assembly comprises:
- a) a polymeric sleeve positioned over the coupling nut and a segment of the cable adjacent the connector, said polymeric sleeve being secured to said coupling nut so as to prevent motion between the sleeve and the nut; and
- b) a layer of encapsulant positioned between at least a portion of the polymeric sleeve and the underlying cable, the encapsulant providing a circumferential environmental seal between the cable and the sleeve while permitting rotational motion between the cable and the sleeve.
- 2. An assembly in accordance with claim 1, wherein the connector is coupled to a connector receptacle mounted with metallic fastening means in a bulkhead and which further comprises a further layer of encapsulant extending from the polymeric sleeve over said fastening means and a portion of the bulkhead.
- 3. An assembly in accordance with claim 1, wherein said polymeric sleeve is a dimensionally recoverable sleeve.
- 4. An assembly in accordance with claim 1, wherein said polymeric sleeve is heat shrinkable.
- 5. An assembly in accordance with claim 1, wherein said encapsulant is a gel.
- 6. An assembly in accordance with claim 5, wherein said gel is reinforced.
- 7. An assembly in accordance with claim 1, wherein said encapsulant is a reinforced silicone gel.
- 8. An assembly in accordance with claim 2, wherein said further layer of encapsulant is contained within an annular-shaped polymeric cap.
- 9. A method of environmentally protecting a cable connection in which an end of a cable is connected to a connector having a coupling nut, which method comprises:
- a) positioning a polymeric sleeve over the coupling nut and a segment of the cable adjacent the connector;
- b) securing the polymeric sleeve to the coupling nut so that motion between the sleeve and the nut is prevented; and
- c) positioning an encapsulant between at least a portion of the sleeve and the underlying cable such that rotational motion is permitted between the cable and the sleeve and an environmental seal is obtained therebetween.
- 10. A method in accordance with claim 9, which further comprises the step of securing the coupling nut to a connector receptacle mounted with metallic fastening means in a bulkhead and positioning a further layer of encapsulant such that it extends over the fastening means and a portion of the bulkhead.
- 11. A method in accordance with claim 10, wherein the further layer of encapsulant is contained in an annular cap and said step of positioning said further layer of encapsulant comprises placing the cap between the coupling nut and then coupling the nut to the connector receptacle.
- 12. A method in accordance with claim 11, wherein the method further comprises the step of applying a force to the further layer of encapsulant.
- 13. A method in accordance with claim 12, wherein the polymeric sleeve is provided with a flange that engages the cap and force is applied to the further layer of encapsulant by coupling the nut to the connector receptacle in such a manner that the flange applies a force to the cap and thereby to the encapsulant.
- 14. A method in accordance with claim 9, wherein the step of positioning an encapsulant between at least a portion of the sleeve and the cable comprises applying a tape of encapsulant around the cable before installing the polymeric sleeve.
- 15. A method in accordance with claim 9, wherein the step of positioning the polymeric sleeve over the coupling nut and cable comprises positioning a heat shrinkable sleeve around the coupling nut and cable and then applying heat to cause the sleeve to shrink into contact with the nut and cable.
- 16. An assembly in accordance with claim 1, wherein the connector comprises an electrical connector.
