Abstract
Abstract A cable branching joint of molded insulation having a built-in conductor, which joint is made by molding synthetic rubber or plastic to the outer circumferences of the conductor, inserting cable conductors into the terminals of this molded insulation and covering them with an insertion-type insulation formed of an elastic insulating material like synthetic rubber, which is attachable and detachable and is applicable irrespective of the cable size and the number of branch terminals.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
105 words
A cable branching joint comprising: a conductive fitting including branches tapering inwardly at their ends, an insulating member molded about said conductive fitting, a cable having insulation surrounding an inner conductor, a metal connector axially coupling at least one cable conductor to a branch of said fitting, an insertion-type insulating cyLinder formed of an elastic insulating material concentrically surrounding said insulating member, said connector and said cable, a cylindrical spacer between said cable insulation and a portion of said cylinder and a first stress cone on the insertion end of said insulating cylinder and a second stress cone provided along an end of said spacer.
