Patent ID: 8872043

Claim:
A device for electric connection to an energy supply conductor for intermediate and high voltage, comprising: an electrically conducting contact part ( 2 ) connected to an intermediate or high-voltage source, and an insulation part comprising a tubular inner sleeve that encloses a portion of the electrically conducting contact part along a portion of a length of the electrically conducting contact part, and an outer shell concentrically surrounding at least a portion of the inner sleeve such that a spacing ( 100 ) exists between the outer shell ( 3 ) and the inner sleeve ( 4 ) and which is open or closed on a side facing away from a narrow end ( 5 ) of the outer shell ( 3 ) connected to the tubular inner sleeve ( 4 ), the insulation part comprising a gas tight thermoplastic polymer, and the outer shell ( 3 ) in the shape of a truncated cone having the narrow end ( 5 ) thereof integrally-formed with the inner sleeve ( 4 ) at an opening through the inner sleeve ( 4 ) and at which the electrically-conducting contact part ( 2 ) has an end for connection with a mating end of a cable ( 11 ).
