Abstract
Abstract A multiple electrical conductor connector assembly in which a distribution cable and multiple feeder cables are connected at a metal terminal block. The cable ends are pushed through a rigid stress relief ring, then through undersized apertures in a resilient cylindrical adapter seal and are then connected to the terminal block. An elastic tubular cover having a closed end is placed over the terminal block and the adapter seal and shrunkfit onto the adapter seal to form a watertight seal around the terminal block.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
140 words
A multiple electrical conductor connector assembly comprising: a resilient cylindrical adapter seal formed with a plurality of apertures extending therethrough parallel to its axis, each said aperture having a normal diameter less than that of a specified cable and being expandable to receive the same, an electrically conductive metal terminal block connecting the conductors at the ends of a distribution cable extending through said apertures in said adapter seal and the conductors at the ends of feeder cables pushed through said apertures in said adapter seal to be tapped into said distribution cable, a rigid stress relief ring lying adjacent said adapter seal and receiving the cables prior to their passing through said adapter seal, and a cover having a closed end extending over said terminal block and forming with said adapter seal a watertight seal around said terminal block.
Claim 2
Dependent Claim
140 words
A multiple electrical conductor connector assembly comprising: a resilient cylindrical adapter seal formed with a plurality of apertures extending therethrough parallel to its axis, each said aperture having a normal diameter less than that of a specified cable and being expandable to receive the same, an electrically conductive metal terminal block connecting the conductors at the ends of a distribution cable extending through said apertures in said adapter seal and the conductors at the ends of feeder cables pushed through said apertures in said adapter seal to be tapped into said distribution cable, a rigid stress relief ring lying adjacent said adapter seal and receiving the cables prior to their passing through said adapter seal, and a cover having a closed end extending over said terminal block and forming with said adapter seal a watertight seal around said terminal block.
Claim 3
Dependent Claim
38 words
The connector assembly of claim 1 wherein said cover comprises an elastic tubular member closed at said one end by a rigid insulator cap having a hollow cylindrical sleeve extending coaxially with said elastic tubular member internally thereof.
Claim 4
Dependent Claim
26 words
The connector assembly of claim 1 wherein said adapter seal is formed with a watertiGht, rupturable membrane across at least one of its said conductor apertures.
