Claims

[Scope of utility model registration request]

(1) Close one end of the large tube in the conductive heat dissipation chamber,
A central conductor whose other end is closed with a conical cylindrical insulating member protruding from the other end of the pipe toward one end, and which is disposed within the pipe and whose one end is electrically connected to the heat radiation chamber. The other end of the tube can be airtightly attached to the opening of a container in which the other end passes through the insulating member and is supported by the insulating member and is filled with a predetermined gas, and the container is inserted into the tube. The center conductor is hollow with one end opening into the heat radiation chamber, and the vicinity of the center conductor supported by the insulating member is connected to the container and the hollow part of the center conductor. A gas bushing, characterized in that the heat radiation chamber and the center conductor are communicated through a communication hole, and the heat radiation chamber and the center conductor are airtightly connected by a sealing member so that the heat radiation chamber and the center conductor are relatively movable.

(2) The gas bushing according to claim 1, wherein the hollow part of the central conductor is partitioned into an outer passage and an inner passage by a hollow member smaller than the inner diameter of the hollow part.

(3) The gas bushing according to claim 1 or 2, wherein the sealing member is a bellows whose both ends are extendably connected to the heat radiation chamber and the central conductor, respectively.

(4) The gas bushing according to claim 1 or 2, wherein the sealing member is an O-ring that is fitted into the heat radiation chamber and slidably supports the center conductor in an airtight manner. .
