Abstract
Abstract An electrical connector for terminating a high voltage cable of the type having an electrically conductive sheath, a cable insulation and an electrical conductor, the connector including an insulator surrounding the cable insulation and the conductor, an electrically conductive electrode embedded in said insulator in spaced relation to the conductor and projecting outwardly from the outer surface of said insulator, and a conductive shield covering the outer surface of the insulator and being spaced from the electrode. A conductive cap is releasably secured to said shield to enclose the outwardly extending end of the electrode and an electrically non-conductive disc is located between the inner surface of the cap and the end of the conductive electrode.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
132 words
A high voltage cable connector having a test point for determining the presence of a voltage in the conductor of the high voltage cable, said connector including an insulating member surrounding the conductor, a conductive electrode partially embedded in said insulator in a spaced relation to said conductor, a conductive shield on the outer surface of said insulating member and being spaced from said electrode, a removable conductive cap electrically connected to said shield and enclosing the exposed portion of said electrode in spaced relation to said electrode, a dielectric disc removable with said cap and positioned between said electrode and said cap for providing a capacitive couple between said cap and said plug and exposing said electrode for direct contact by testing means when said cap and said disc are removed.
Claim 2
Dependent Claim
132 words
A high voltage cable connector having a test point for determining the presence of a voltage in the conductor of the high voltage cable, said connector including an insulating member surrounding the conductor, a conductive electrode partially embedded in said insulator in a spaced relation to said conductor, a conductive shield on the outer surface of said insulating member and being spaced from said electrode, a removable conductive cap electrically connected to said shield and enclosing the exposed portion of said electrode in spaced relation to said electrode, a dielectric disc removable with said cap and positioned between said electrode and said cap for providing a capacitive couple between said cap and said plug and exposing said electrode for direct contact by testing means when said cap and said disc are removed.
