Abstract
Abstract A pair of hollow cylindrical parts are received onto a shielded cable and can be threaded together to clampingly engage conductive rings pressing them into full circumferential contact with the cable shield. One of the cylindrical parts is secured to a suitable electrical ground point (e.g., welding to deck of ship).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
152 words
A device for establishing connection between electrical ground and a cable shield, comprising: a cable having an external shield; first and second hollow metallic cylindrical means received on the cable over the cable shield, said cylindrical means including threads for releasably joining said cylindrical means to one another; generally annular conductive means located about the cable shield and within at least one of the cylindrical means including first ring means with a bore enabling contacting receipt about the cable shield, an annular metal plate received about the first ring means, and second ring means received about said annular metal plate, said first and second ring means and annular metal plate being clampingly engaged by the threading of said first and second cylindrical means together to effect electrical contact between the cable shield and said first and second cylindrical means; and means for conductively affixing one of the cylindrical means to electrical ground.
Claim 2
Independent Claim
152 words
A device for establishing connection between electrical ground and a cable shield, comprising: a cable having an external shield; first and second hollow metallic cylindrical means received on the cable over the cable shield, said cylindrical means including threads for releasably joining said cylindrical means to one another; generally annular conductive means located about the cable shield and within at least one of the cylindrical means including first ring means with a bore enabling contacting receipt about the cable shield, an annular metal plate received about the first ring means, and second ring means received about said annular metal plate, said first and second ring means and annular metal plate being clampingly engaged by the threading of said first and second cylindrical means together to effect electrical contact between the cable shield and said first and second cylindrical means; and means for conductively affixing one of the cylindrical means to electrical ground.
Claim 3
Dependent Claim
61 words
A device as in claim 1, in which grommet means are received with one of the cylindrical means, said grommet means being driven against the annular conductive means on threading of the first and second cylindrical means together in such direction as to urge the annular means into contact with both the cable shield and a surface of a cylindrical means.
Claim 4
Dependent Claim
19 words
A device as in claim 1, in which said first and second ring means have a split body wall.
Claim 5
Dependent Claim
14 words
A device as in claim 1, in which the affixing means includes a weldment.
Claim 6
Dependent Claim
50 words
A device as in claim 1, in which electrical ground is a conductive wall member having an opening therein through which one of the metallic cylindrical means extends, and the affixing means includes a weldment interconnecting the wall member and said metallic cylindrical means extending through the wall member opening.
Claim 7
Dependent Claim
17 words
A device as in claim 1, in which the weldment extends completely about the wall member opening.
Claim 8
Dependent Claim
24 words
A device as in claim 1, in which the second ring means include a pair of conductive rings separated by a force transmitting means.
Claim 9
Dependent Claim
20 words
A device as in claim 1, in which the force transmitting means includes an O-ring constructed of a resilient material.
