〔発明の利用分野〕
本発明は、真空遮断器用真空バルブのシールド支持構造
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a shield support structure for a vacuum valve for a vacuum circuit breaker.
（発明の背景〕
従来、真空バルブで中間シールドをろう付により取付け
た例を、第ｔｔｉおよび第２図により説明する。(Background of the Invention) An example of conventionally attaching an intermediate shield to a vacuum valve by brazing will be explained with reference to FIG. tti and FIG.

す。The insulating cylinder 1 is made of alumina ceramic, and has a protrusion 1'a on the inner circumference, and a metallized surface treatment 1b is applied to the side surface of the protrusion 1a. The support ring 2 is made of a Fe-N1-Go gold alloy whose thermal expansion coefficient matches that of the ceramic tube, or an Fe-
Using a Ni alloy, the surface is plated with Ni. Further, the intermediate shield 3 is generally made of stainless steel, but in this case, Nj plating is applied as a pretreatment for brazing.
以上の三部品を組合せ水素雰囲気、または、真空中でろ
う材部４とろう材部５を同時にろう付する。The above three parts are combined and the brazing material part 4 and the brazing material part 5 are simultaneously brazed in a hydrogen atmosphere or in a vacuum.

体として高価で工程が長いことである。The problems with this method are that the metallization process inside the alumina ceramic cylinder requires advanced technology and a long process, that the support ring requires expensive materials, and that each part is soldered together for brazing. Ni plating is required, and the overall process is expensive and long.
第３図、第４図および第５図により本発明の一実施例を
説明する。An embodiment of the present invention will be described with reference to FIGS. 3, 4, and 5. FIG.

音が発生する。なお、８は点溶接を示す。A protrusion 1a is provided on the inner circumference of the insulating outer cylinder 1 as in the conventional product, but no metallization treatment is performed. Intermediate shield 3 and
The support ring 6 is made of stainless steel and does not require Ni plating. At least three or more cushions 7 made of small pieces of thin sheet metal having spring properties are attached in the circumferential direction by spot welding to the portion of the intermediate shield 3 that contacts the protrusion 8a. Insert this into the insulating outer cylinder 1, and from the opposite side support ring 6.
Insert and tighten, and tighten the ends of both parts to 7I” i G.
It is fixed by a welded part 9 by welding. The cushion plate 7 is provided to prevent the intermediate shield 3 from wobbling. Without this, the welded portion 9 would contract, creating a gap between it and the protrusion 1a, and when the vacuum valve was energized, noise would be generated due to electromagnetic vibration. Note that 8 indicates spot welding.
本発明によれば、セラミックにメタライズ処理が不要で
あり、また、サポートリングと中間シールドはめつきが
不要であり、工程短縮と原価低減に大きく寄与する。According to the present invention, there is no need to metalize the ceramic, and there is no need for plating between the support ring and the intermediate shield, which greatly contributes to shortening the process and reducing costs.
