Abstract
Abstract A cable connection is environmentally protected using an assembly which comprises a polymeric sleeve positioned over the coupling nut of the connector and a segment of the cable adjacent the connector, the polymeric sleeve being secured to said coupling nut so as to prevent motion between the sleeve and the nut and 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. A further layer of encapsulant preferable extends from the coupling nut over the hardware mounting the connector receptacle into a bulkhead. This further layer of encapsulant is preferable contained in a cap to which a force is applied by a flange provided in the polymeric sleeve. The encapsulant is preferable a silicone gel.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
108 words
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.
Claim 2
Dependent Claim
108 words
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.
Claim 3
Dependent Claim
48 words
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.
Claim 4
Dependent Claim
16 words
An assembly in accordance with claim 1, wherein said polymeric sleeve is a dimensionally recoverable sleeve.
Claim 5
Dependent Claim
14 words
An assembly in accordance with claim 1, wherein said polymeric sleeve is heat shrinkable.
Claim 6
Dependent Claim
13 words
An assembly in accordance with claim 1, wherein said encapsulant is a gel.
Claim 7
Dependent Claim
12 words
An assembly in accordance with claim 5, wherein said gel is reinforced.
Claim 8
Dependent Claim
15 words
An assembly in accordance with claim 1, wherein said encapsulant is a reinforced silicone gel.
Claim 9
Dependent Claim
20 words
An assembly in accordance with claim 2, wherein said further layer of encapsulant is contained within an annular-shaped polymeric cap.
Claim 10
Independent Claim
101 words
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.
Claim 11
Independent Claim
101 words
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.
Claim 12
Dependent Claim
50 words
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.
Claim 13
Dependent Claim
46 words
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.
Claim 14
Dependent Claim
24 words
A method in accordance with claim 11, wherein the method further comprises the step of applying a force to the further layer of encapsulant.
Claim 15
Dependent Claim
56 words
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.
Claim 16
Dependent Claim
39 words
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.
Claim 17
Dependent Claim
50 words
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.
Claim 18
Dependent Claim
14 words
An assembly in accordance with claim 1, wherein the connector comprises an electrical connector.
