【考案の詳細な説明】
本考案はコロナリングの取付を必要とする高電
圧での使用を目的とする電子管の改良に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an electron tube intended for use at high voltages requiring the installation of a corona ring.
一般に放送用あるいは誘導、誘電加熱等の工業
用で使用される大電力電子管は高電圧が印加され
る為高電圧印加電極である陽極、格子の封入皿部
をスパークによる破壊（例えば穴あき）から保護
する目的で金属で出来たコロナリングが取付けら
れている。 Generally, high-power electron tubes used for broadcasting or industrial applications such as induction and dielectric heating have high voltage applied to them, so the anode, which is the high voltage application electrode, and the enclosing plate part of the grid are protected from damage caused by sparks (for example, holes). A metal corona ring is attached for protection.
従来この種の電子管は第１図に示す如く、既に
排気完了した密閉管１のグリツド端子１１あるい

あること、ネジ止めを少なくしたり、ネジ止めを
忘れたり緩んだりした場合、この部分から高周波
電力の供給を行うことが多いので高周波ロスが増
える欠点があつた。 Conventionally, this type of electron tube has a corona ring 2 made of metal such as brass or aluminum as a separate part on the grid terminal 11 or the anode flange 12 or both of the sealed tube 1 which has already been evacuated, as shown in FIG. They are attached using screws or the like while maintaining the interval dimension a determined by the voltage used. This conventional method increases the number of parts because the corona ring is made as a separate part, requires a mounting process, and is complicated work when there are many screws. If the lock is forgotten or loosened, high-frequency power is often supplied from this part, which has the disadvantage of increasing high-frequency loss.
本考案の目的はこれらの欠点を除いたコロナリ
ング付電子管を提供するものである。 The object of the present invention is to provide an electron tube with a corona ring that eliminates these drawbacks.
本考案は陽極封入皿の一部がコロナリングを形
成していることを特徴とする。 The present invention is characterized in that a part of the anode enclosure plate forms a corona ring.

多くの利点がある。 That is, as shown in FIG. 2, an anode 21, which is a high voltage application electrode, or a metal enclosure plate (Kovar, copper, etc.) 22, which is an introduction part for a grid (not shown),
Extend one or both of 23 as shown in the dotted line, bend the tip in the direction of the counter electrode, and process the tip into a circle (for example, R cutting, curling, etc.)
Also, it is formed so as to maintain the distance dimension a from the counter electrode introduction part. Since this enclosure dish is used as a part when brazing the stem or processed anode, the electron tube of the present invention shown in FIG. 2 is formed when the sealed tube is assembled. Since this enclosure plate is attached by brazing, there are many advantages such as less high frequency loss, no complicated screw fixing, and no special installation process required.

ロナリングを取付けることも可能であることはい
うまでもないことである。 Of course, it is also possible to separately attach a corona ring to the tip of the rounded enclosure dish.
