Abstract
Abstract A system for grounding telecommunications cable rack assemblies and the like. The system comprises the positioning of an electrical conductor element beneath each end of at least one of the U-shaped clamp elements of a clamping junction between adjacent cable rack sections. The conductor elements comprise means for piercing the non-electrically conductive painted surface of the adjacent cable rack sections and forming electrical continuity therebetween through the clamping junction when the U-shaped clamp elements thereof are tightened on the adjacent cable rack sections.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
185 words
A method of grounding telecommunications cable rack comprising: providing at least two metal cable rack sections in adjacent relationship, said cable rack sections being coated with a non-electrically conductive material on at least a portion of the surface thereof; connecting said cable rack sections with one or more electrically conductive clamping junctions of the type comprising upper and lower clamp elements having securement means extending therebetween for urging said clamp elements together and into contact with said adjacent cable rack sections; positioning an electrical conductor element beneath each end of at least one of said clamp elements prior to tightening of said clamp elements together on said adjacent cable rack sections, said conductor elements comprising means for piercing the non-electrically conductive material on the surface of said cable rack sections; tightening said clamp elements together on said adjacent cable rack sections so as to cause said electrical conductor elements positioned between said clamp elements and said adjacent cable rack sections to pierce the non-electrically conductive material on the surface of each of said cable rack sections and thereby to form a continuous electrical connection therebetween.
Claim 2
Independent Claim
185 words
A method of grounding telecommunications cable rack comprising: providing at least two metal cable rack sections in adjacent relationship, said cable rack sections being coated with a non-electrically conductive material on at least a portion of the surface thereof; connecting said cable rack sections with one or more electrically conductive clamping junctions of the type comprising upper and lower clamp elements having securement means extending therebetween for urging said clamp elements together and into contact with said adjacent cable rack sections; positioning an electrical conductor element beneath each end of at least one of said clamp elements prior to tightening of said clamp elements together on said adjacent cable rack sections, said conductor elements comprising means for piercing the non-electrically conductive material on the surface of said cable rack sections; tightening said clamp elements together on said adjacent cable rack sections so as to cause said electrical conductor elements positioned between said clamp elements and said adjacent cable rack sections to pierce the non-electrically conductive material on the surface of each of said cable rack sections and thereby to form a continuous electrical connection therebetween.
Claim 3
Dependent Claim
153 words
A telecommunications cable rack assembly comprising: a plurality of metal cable rack sections, said cable rack sections being coated with a non-electrically conductive material on at least a portion of the surface thereof; a plurality of electrical conductor clamping junctions connecting the ends of adjacent cable rack sections, said clamping junctions each comprising upper and lower clamp elements with securement means for urging said clamp elements together and into contact with the ends of said adjacent cable rack sections; and a plurality of electrical conductor elements wherein an electrical conductor element is positioned beneath each end of at least one of said clamp elements of said plurality of clamping junctions, said conductor elements each comprising means for piercing the non-electrically conductive material on the surface of a respective one of said adjacent cable rack sections; whereby a continuous electrical connection is formed between said plurality of cable rack sections to facilitate grounding thereof.
Claim 4
Dependent Claim
153 words
A telecommunications cable rack assembly comprising: a plurality of metal cable rack sections, said cable rack sections being coated with a non-electrically conductive material on at least a portion of the surface thereof; a plurality of electrical conductor clamping junctions connecting the ends of adjacent cable rack sections, said clamping junctions each comprising upper and lower clamp elements with securement means for urging said clamp elements together and into contact with the ends of said adjacent cable rack sections; and a plurality of electrical conductor elements wherein an electrical conductor element is positioned beneath each end of at least one of said clamp elements of said plurality of clamping junctions, said conductor elements each comprising means for piercing the non-electrically conductive material on the surface of a respective one of said adjacent cable rack sections; whereby a continuous electrical connection is formed between said plurality of cable rack sections to facilitate grounding thereof.
