Abstract

A grounding block is provided for engaging at least one continuous coaxial cable. The grounding block includes an electrically conductive base member having an upper surface, a lower surface, a front surface and a rear surface. The upper surface of the base member includes a hemicylindrical trough extending between the front surface and the rear surface of the base member. The hemicylindrical trough includes a first enlarged radius portion disposed adjacent to the front surface, a second enlarged radius portion disposed adjacent to the rear surface, and reduced radius portion extending between the first and second enlarged radius portion. A corresponding electrically conductive cap member is also provided. A fastener is provided for fastening together the cap member and the base member to align the hemicylindrical troughs of the base member and the cap member to form a cylindrical bore extending between the front surfaces of the base and cap members, and the rear surfaces of the base and cap members.

Dependent claims

A grounding block for engaging at least one continuous coaxial cable having a first sheathed portion, a second sheathed portion and a sheath removed portion disposed between the first sheathed portion and the second sheathed portion, the grounding block comprising:

(1) an electrically conductive base member having an upper surface, a lower surface, a front surface and a rear surface, the upper surface including a hemicylindrical trough extending between the front surface and the rear surface of the base member, the hemicylindrical trough including a first enlarged radius portion disposed adjacent to the front surface, a second enlarged radius portion disposed adjacent to the rear surface, and a reduced radius portion extending between the first and second enlarged radius portions,
(2) an electrically conductive cap member having an upper surface, a lower surface, a front surface and a rear surface, the lower surface including a hemicylindrical trough extending between the front surface and the rear surface of the cap member, the hemicylindrical trough including a first enlarged radius portion disposed adjacent the front surface, a second enlarged radius portion disposed adjacent to the rear surface, and a reduced radius portion extending between the first and second enlarged radius portions, and
(3) fastening means for fastening together the cap member and the base member to align the hemicylindrical troughs of the base member and the cap member to form a cylindrical bore extending between the front surfaces of the base and cap members, and the rear surface of the base and cap members, the cylindrical bore including a first enlarged diameter portion for snugly receiving the first sheathed portion of the continuous coaxial cable, a second enlarged diameter portion for snugly receiving the second sheathed portion of the continuous coaxial cable, and a reduced diameter portion extending between the first and second enlarged diameter portions for receiving the sheath removed portion of the continuous coaxial cable.

A grounding system for use with a transmission tower comprising,

(1) a continuous coaxial cable having a first sheathed portion, a second sheathed portion, and a sheath removed portion extending between the first and second sheathed portions,
(2) an electrically conductive grounding block having an upper surface, a generally planar lower surface, a front surface and a rear surface, a cylindrical bore extending between the front surface and the rear surface, the cylindrical bore including (a) a first enlarged diameter portion disposed adjacent to the front surface and sized for snugly receiving the first sheathed portion of the coaxial cable, (b) a second enlarged diameter portion disposed adjacent the rear surface, and sized for snugly receiving the second sheathed portion of the coaxial cable, and (c) a reduced diameter portion for snugly receiving the sheath-removed portion of the coaxial cable,
(3) an electrically conductive anti-oxidizing means disposed between the sheath removed portion of the coaxial cable and the cylindrical bore for filling any spaces therebetween,
(4) an electrically conductive mounting fixture having a generally planar surface having an area at least as large as the area of the lower surface of the grounding block, and
(5) fastening means for fastening the grounding block to the mounting fixture to place the lower surface of the grounding block in an electrically conductive contact with the planar surface of the mounting fixture to form an electrically conductive surface-to-surface contact area between the grounding block and the mounting fixture at least as large as the area of the lower surface of the grounding block.
