ABSTRACT:
A high voltage cable/connector assembly of an improved design for substantially minimizing or eliminating damaging corona and voltage arc-over effects. The assembly in accordance with the invention includes a high voltage cable having a cable shield (e.g., a braided shield), a high voltage metal connector secured to and surrounding a portion of the cable and in physical and electrical contact with the cable shield, and a metal horn-shaped corona shield connected in series with the metal connector and defining a cavity through which a portion of the cable, including a center conductor and a surrounding bare plastic dielectric, passes longitudinally. The corona shield serves to eliminate sharp edges or abrupt terminations in the vicinity of the cable shield, metal connector and corona shield so that corona discharge is effectively prevented. The portion of the cable passing through the corona shield is selected to have a length to place the termination of the center conductor of this portion at a distance from the corona shield for minimizing the possibility of voltage arc-over from the center conductor to the corona shield and any other metal parts of the assembly.
