る。A conventional discharge tube of this type, in which one electrode is formed in a cylindrical shape, has a cylindrical shape in order to supply a high-pressure inert gas into the internal space 104 of the closed vessel 103, as shown in FIG. The pipe-shaped electrode 101 to which the formed electrode piece 101a is fixed at the joining portion 101b is sealed by caulking as shown in the figure, and hermetically welded after injecting an inert gas. The discharge is performed between the bottom of the electrode piece 101a and the electrode 102, and the pressure is adjusted when an inert gas is introduced in order to obtain a fixed discharge characteristic.
〔考案が解決しようとする課題〕 この従来の放電管は、パイプ状の電極101の通孔性を
損なわないように電極片101aを固着しなければならない
ため、製造性が悪くかつ部品点数が多くなるという欠点
があった。[Problem to be Solved by the Invention] In this conventional discharge tube, since the electrode piece 101a must be fixed so as not to impair the hole permeability of the pipe-shaped electrode 101, the productivity is poor and the number of parts is large There was a disadvantage of becoming.

る。The discharge tube of the present invention comprises: a tubular hermetic container; a first electrode hermetically fixed to one end of the container and having a cylindrical portion provided inside the container; A second electrode disposed opposite to the first electrode such that one end of the self that is fixed and extends inside the container enters the inside of the cylindrical portion; and an inert gas sealed in the container. The first electrode is formed of a pipe-shaped member, one end of this member is enlarged to form the cylindrical portion and a projection is formed on the enlarged cylindrical bottom portion, On the other hand, the other end of the member is hermetically sealed by caulking, so that a spark discharge between the first and second electrodes is generated at the location of the projection on the cylindrical bottom.
次に本考案について図面を参照して説明する。 Next, the present invention will be described with reference to the drawings.

の外側端部は図示のようにかしめ封着されている。FIG. 1 is a longitudinal sectional view of one embodiment of the present invention. The pipe-shaped electrode 21 has a cylindrical portion 21a formed by enlarging and molding a portion facing the electrode 102, and is arranged coaxially with the other electrode 102 to stabilize discharge characteristics. Also, the cylindrical portion 21a
A protrusion 21b is formed at the bottom of the electrode 102, and the discharge generated between the electrode 102 and the discharge surface 102a of the other electrode 102 is fixed at a fixed place to stabilize the discharge. After sealing each electrode in the sealed container 103,
A high-pressure inert gas is injected into the internal space 104 through the pipe-shaped electrode 21 in order to obtain predetermined discharge characteristics.
Is sealed by caulking as shown.
以上説明したように本考案は、パイプ状電極の一端を

上すると共に、小形化できるという効果がある。As described above, the present invention not only has an effect of enlarging and forming one end of the pipe-shaped electrode and forming a projection on the bottom thereof, but also stabilizing the discharge. Since it is not necessary to process the pieces separately and fix them, the cost can be reduced by reducing the number of parts and the number of processing steps, and since there is no fixing part, the reliability is improved and the size can be reduced. There is.
