構造に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support structure for an electron gun for an electron tube, and more particularly to a structure for connecting an end of an electronic component or an end of a support attached to an electronic component to a glass rod serving as an insulating support member. .

記端部をガラス中に挿入し固定している。 As is well known, in an electron tube electron gun, in order to support several main electrode parts while insulating them from each other, each electrode part is held to a predetermined size by a jig, and the end of each electrode part or the electrode part is A heated and softened glass rod is pressed against the end of the support attached to the glass, and the end is inserted into the glass and fixed.

定となる欠点があつた。 However, each electrode component is usually made of stainless steel, iron, nickel alloy, etc., and has a higher coefficient of linear expansion than a glass rod, so it cannot be inserted into a glass rod and heated to the same temperature as the glass rod. Even if the glass rod and electrode parts are in close contact with the glass, if the glass rod or electrode parts cool and contract afterwards, looseness will occur at the joint. As a result, the relative positional dimensions of the electrode components become unstable, resulting in unstable characteristics of the electron gun.

の構成よりなる。 An embodiment of the present invention will be described below with reference to FIGS. 1, 2, and 3. As shown in Figure 1,
Each end of the heater support strap 1, the support 21 of the cathode support 2, the support 41 of the first electrode 3, the second electrode 4, the support 51 of the third electrode 5, and the support 61 of the fourth electrode 6 is It is embedded and held in a glass rod 7. Said cathode support 2
A cathode support sleeve 22 is fixed to the cathode support sleeve 22 by a hermetic glass 23, and the cathode 8 is further welded to the cathode support sleeve 22. A heater 9 supported by a heater support strap 1 is disposed inside the cathode 8 . Further, the cathode 8 has an alkaline earth metal oxide 81, which is an electron emissive substance, coated on its upper part, and is heated by a heater 9 when the electron tube is operated. Further, a U-shaped portion is formed in a part of the first electrode 3, and the lateral expansion shown in FIG. 1 is partially absorbed by this U-shaped portion. The above is a conventionally known configuration.

2の中へ十分充満しなく、結合は完全でない。 Here, the temperature of the cathode support 2, cathode support support 21, cathode support sleeve 22, first electrode 3, cathode 8, etc. increases during operation of the electron tube, which greatly affects the characteristics of the electron tube. The influence of the first electrode 3 is large. Other second electrodes 4, second electrode supports 41,
The third electrode 5, the third electrode support 51, the fourth electrode 6, and the fourth electrode support 61 have a relatively low temperature rise, and the influence is not large. Therefore, the stability of the bond between the first electrode 3 and the glass rod 7 is most important. In order to improve the stability of this bond, a penetrating hole 32 is provided in the end 31 of the first electrode 3, and the penetrating hole 32 is filled with the glass of the glass rod 7, so that the end 31 shrinks. The glass in the hole 32 passing through the hole 32 may be compressed. However, since glass has a high viscosity, when inserting the end 31 of the first electrode 3 into the heated and softened glass rod 7, the end 31 pushes a part of the glass rod 7 apart and enters the glass rod 7. The glass of rod 7 has a through hole 3
2 is not fully filled and the union is not complete.

中にガラスが十分充満される。 To solve this problem, the present invention provides support for the cathode support 2 in close proximity to the hole 32 perpendicular to and penetrating the end 31 of the first electrode 3, as shown in enlarged views in FIGS. 2 and 3. The body 21 is embedded in the glass rod 7. That is, the glass rod 7 softened by heating
When inserting the support 21 into the hole 32, the support 21 is provided close to the hole 32 which is perpendicular to and penetrates the end of the first electrode 3, so that the glass rod 7 displaced by the support 21 is A portion is pushed into the through hole 32 of the first electrode 3, and the through hole 32 is sufficiently filled with glass.

Moreover, when the gap was widened, glass could not be sufficiently introduced into the hole 32 through which the first electrode 3 was penetrated by the support body 21 .

An electron gun for an electron tube with the same function can be obtained.
