Abstract
Abstract The disclosure relates to an electrical connector of the type used in underground utility applications wherein a number of secondary cables may be terminated to a commoning plate and wherein any one of the cables may be detached from the commoning plate without disturbing the other cables. The connector comprises a commoning block of electrically conducting material, preferably aluminum, having tapered holes therethrough, for receiving an electrical cable with connector thereon. The connector makes watertight fit with a reamed out portion of the commoning plate and is secured thereto, a watertight member being positioned on the opposite side of the commoning block to provide a watertight underground connection.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
216 words
A connector for an underground utility application, comprising: a block of conductive material, a coating of insulation and sealing material covering said block, said block being provided with a plurality of apertures extending entirely through said block, each of said apertures including a tapered sidewall, portions of said coating encircling each end of said apertures, an electrically conductive terminal having a recessed portion at one end thereof for connection to an electrical cable, the other end of said terminal being tapered and of a configuration complimentary to the tapered sidewall of each of said tapered apertures provided in said block, said tapered end being received in mating registration within a tapered sidewall of a selected aperture provided in said block, sleeve-sealing means of insulation material encircling a portion of said electrical terminal, threaded connection means protruding from the end of said tapered end and received in said selected aperture, and covering means positively connected to said threaded connection means, said covering means and said sleevesealing means overlying and in sealing compression against said coating portions encircling respectively said ends of the selected aperture provided in said block, said threaded connection means cooperating with said sleeve-sealing means and said covering means and simultaneously applying sealing compression of said sleeve-sealing means and said covering means against said coating.
