<p>PROBLEM TO BE SOLVED: To facilitate the connection work by forming recesses in a conductor coupling and a center conductor, and coupling these recesses by a conductive contactor, and coupling the opening of an insulating sleeve and the insulating layer of an insulating bus. SOLUTION: A conductive disc 12 is arranged within an insulating sleeve 11, and on both sides of this conductive disc 12, a pair of conductor couplings 13 and 14 extended in axial direction of the opening 11a are provided in a range. Then, at the inner faces of the conductor couplings 13 and 14 in a pair, screw holes 13a and 14a for support mounting are made, and at the outer faces, ring-shaped recesses 13b and 14b in contact with a conductive contactor 40 are made. These recesses 13b and 14b are coupled with each other by the conductive contactor 40, and the opening 11a of an insulating sleeve 11 and the solid insulating layer 22 of an insulating bus 20 are coupled with each other by an insulating cylinder 50. Hereby, the number of required parts and the manhour in mounting can be reduced.</p> |
