Abstract
Abstract A cable terminal assembly to be secured to an end portion of a high frequency cable of the type having an outer and a coaxial tubular fluidtight inner conductor through which a cooling fluid is to be circulated. Conductor means is provided on the assembly which extends radially of the outer and inner conductors of the cable when the assembly is secured to the end portion thereof, and which is arranged to be electrically conductively connected with the inner conductor of the cable. Conduit means is arranged to be axially connected with the inner conductor of the cable so as to supply fluid to or receive fluid from the inner conductor. Shielding means serves to shield both the surroundings of the cable terminal and also cooling fluid flowing in the conduit means from the electromagnetic field created about the terminal when the cable transmits high frequency energy.

Claim 1
Independent Claim
136 words
For use with a high frequency cable of the type having an outer and a coaxial tubular fluidtight inner conductor adapted for circulation of a cooling fluid therethrough, a cable terminal assembly to be secured to an end portion of the cable and comprising conductor means extending radially of said conductors when said assembly is secured to the cable and arranged to be in electrically conductive contact with said inner conductor; conduit means for passage of the cooling fluid therethrough, said conduit means communicating with and constituting an axial fluidconducting extension of said inner conductor when said assembly is secured to the cable; and shielding means shielding the ambient regions of said assembly, as well as cooling fluid in said conduit means, from the electromagnetic field which is generated when the cable transmits high frequency energy.
