Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
133 words
A plug, male or female, for an underwater electrical cable comprising: an electrical contact insert; at least one conductive pin extending from said electrical contact insert; at least one insulated conductor extending from said electrical cable and into conductive contact with said conductive pin; a non-conductive material disposed surrounding the locale of said conductive contact of said conductive pin and said insulated conductor; a seal boot forming a cup partially surrounding the non-conductive material, with the electrical contact insert being on the opposite side of the non-conductive material from the seal boot; a polymeric foam at least partially surrounding said seal boot; and an outer boot at least partially surrounding said polymeric foam, a rim of the seal boot being secured between a recess in the electrical contact insert and the outer boot.
Claim 2
Dependent Claim
133 words
A plug, male or female, for an underwater electrical cable comprising: an electrical contact insert; at least one conductive pin extending from said electrical contact insert; at least one insulated conductor extending from said electrical cable and into conductive contact with said conductive pin; a non-conductive material disposed surrounding the locale of said conductive contact of said conductive pin and said insulated conductor; a seal boot forming a cup partially surrounding the non-conductive material, with the electrical contact insert being on the opposite side of the non-conductive material from the seal boot; a polymeric foam at least partially surrounding said seal boot; and an outer boot at least partially surrounding said polymeric foam, a rim of the seal boot being secured between a recess in the electrical contact insert and the outer boot.
Claim 3
Dependent Claim
19 words
The plug of claim 1 wherein the seal boot positions the insulated conductors in a central, axially aligned location.
Claim 4
Dependent Claim
28 words
The plug of claim 1 wherein the seal boot and outer boot are rubber, the non-conductive material is silicone grease, and the polymeric foam is closed-cell and flexible.
Claim 5
Dependent Claim
13 words
The plug of claim 1 wherein the polymeric foam is one integral piece.
Claim 6
Dependent Claim
13 words
The plug of claim 4 wherein the polymeric foam is formed in situ.
Claim 7
Dependent Claim
13 words
The plug of claim 1 wherein the polymeric foam is formed in situ.
Claim 8
Dependent Claim
17 words
The plug of claim 6 wherein the outer boot is clamped to a recess in the insert.
Claim 9
Dependent Claim
21 words
The plug of claim 6 wherein the outer boot is clamped between a recess in the insert and a plug boot.
Claim 10
Dependent Claim
130 words
A plug, male or female, for an underwater electrical cable comprising: an electrical contact insert; at least one conductive pin extending from said electrical contact insert; at least one insulated conductor extending from said electrical cable and into conductive contact with said conductive pin; a non-conductive material disposed surrounding the locale of said conductive contact of said conductive pin and said insulated conductor; a seal boot forming a cup partially surrounding the non-conductive material, with the electrical contact insert being on the opposite side of the non-conductive material from the seal boot; a polymeric foam at least partially surrounding said seal boot; and an outer boot at least partially surrounding said polymeric foam, a rim of the seal boot being secured between the electrical contact insert and the outer boot.
Claim 11
Dependent Claim
