Abstract
Abstract Disclosed herein is a splice connector housing comprising a tubular elastomeric sleeve having first and second coaxial end portions which receive the insulation and shield of first and second cables, respectively, and, between the end portions, a central portion coaxial with the end portions and of substantially uniform wall thickness and which receives and resiliently grips a compression connector crimped to the bared ends of the conductors of the cables. The central portion further has a plurality of circumferentially spaced, similar radially resiliently, dilatable inner areas the inner surfaces of which define a circle normally of lesser diameter than both the cable insulation and the compression connector and a like number of circumferentially spaced similar relieved outer areas the inner surfaces of which define a circle of greater diameter than the cable shield. Each outer area merges smoothly, circumferentially, with two inner areas. Also disclosed herein is a completed splice joint of two shielded cables employing the housing.
