ることにある。However, the conventional vacuum valve as described above has a problem that the brazing portion between the arc shield and the support metal determines the life of the vacuum valve. That is, the vacuum valve receives a large impact every time the internal contact is opened and closed. For this reason, an impact load is repeatedly applied to the brazing portion between the arc shield and the support metal, and the life of the vacuum valve is determined by the fixing strength of the brazing portion. If the fixing strength between the arc shield and the support metal is higher than before, the reliability of the vacuum valve can be further improved. The purpose of this invention is
An object of the present invention is to make the adhesion between the arc shield and the support metal stronger than before.

In a vacuum valve in which an arc shield is brazed to a support fitting attached to the inner wall of the vacuum vessel, the support fitting may have elasticity and may be bent so as to press the arc shield. . As a result, the force of the support fitting pressing the arc shield is added to the fixing force by brazing, so that the fixation between the arc shield and the support fitting becomes stronger than before.

In this vacuum valve, the support fitting may have elasticity and may be bent so as to form a peak between the vacuum vessel and the arc shield. Thereby, in the heating step of melting the brazing portion, the thermal stress generated in the brazing portion due to the difference in the coefficient of thermal expansion between the supporting bracket and the arc shield is absorbed by the peaks of the supporting bracket, and the arc shield, the supporting bracket and Becomes stronger than before.

In such a vacuum valve, the arc shield may be fixed to the support by a rivet. Since the fixation by the rivet is stronger than the brazing, the fixation between the arc shield and the support metal becomes stronger than before.

分には同一参照符号を付け詳細な説明は省略する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments. FIG. 1 is a cross-sectional view of a main part showing a configuration of a vacuum valve according to an embodiment of the present invention, and corresponds to a cross-sectional view taken along line YY of FIG. An elastic supporting member 10 is interposed between the vacuum vessels 1A and 1B, and a mounting portion 12A of the supporting member 10 is provided with an embossed portion 4A of the arc shield 4.
It is bent at the place. A brazing material 8 is arranged at a contact portion between the embossed portion 4A and the support fitting 10, and the brazing material 8 is melted by heating the entire vacuum valve at a high temperature.
The arc shield 4 and the support fitting 10 are brazed. FIG. 1 is different from the configuration of FIG. 8 in that the support bracket 10 has elasticity, so that the arc shield 4 is pressed toward the inner diameter side by being bent,
However, it is always trying to return to the position of the dotted line 10S. The rest of FIG. 1 is the same as the conventional configuration, and the same portions are denoted by the same reference numerals and detailed description thereof will be omitted.

ことができ、真空バルブの信頼性が従来より向上する。Although the support fitting 9 shown in FIG. 8 is bent, the shape shown in FIG. 8 is maintained even when no external force is applied to the support fitting 9. That is, the support fitting 9
No force is applied to the arc shield 4. Therefore, the support fitting 9 and the arc shield 4 are fixed only by brazing. In the configuration of FIG. 1, in addition to the fixing force by brazing, a force for pressing the arc shield 4 to the inner diameter side is applied by the support fitting 10, so that the support fitting 10 and the arc shield 4 are fixed to each other in FIG. 8. Be more robust. Therefore, the fixing portion between the support fitting 10 and the arc shield 4 can sufficiently withstand repeated impacts at the time of contact opening and closing, and the reliability of the vacuum valve is improved as compared with the related art.

いる。図２のその他は、図１の構成と同じである。FIG. 2 is a sectional view of a main part showing a structure of a vacuum valve according to another embodiment of the present invention. The elastic support 12 is bent, and a peak 12A is formed between the vacuum vessels 1A and 1B and the arc shield 4. However, unlike the case of FIG. 1, the support fitting 12 is held in the shape of FIG. 2 in a state where no external force is applied to the support fitting 12, unlike the case of FIG. 1. The rest of FIG. 2 is the same as the configuration of FIG.

がより向上する。In FIG. 2, in the heating step of melting the brazing portion, a thermal stress is generated in the brazing portion due to a difference in the coefficient of thermal expansion between the support fitting 12 and the arc shield 4.
Conventionally, since the thermal stress remains in the brazed portion, the fixing force of the brazed portion is weakened accordingly. Due to the formation of the ridges 12A of the support fittings 12, even if the support fittings 12 and the arc shield 4 are thermally deformed in the heating step, the inclination of the ridges 12A changes due to their elasticity, and heat is applied to the brazing portion. No stress is generated. For this reason, the fixing between the support fitting 12 and the arc shield 4 becomes stronger than in the conventional case, and the reliability of the vacuum valve is further improved.

A is formed. Further, the support member 17 is bent so as to apply a force for pressing the arc shield 4 toward the inner diameter side similarly to the case of FIG. 1, and is always returning to the position of the dotted line 17S. The rest of FIG. 3 is the same as the configuration of FIG. In the configuration shown in FIG. 3, the residual force due to the heating of the brazing portion is eliminated, and a force for pressing the arc shield 4 toward the inner diameter side is applied. Therefore, the fixing force of the brazing portion becomes stronger than in the case of FIG.

It is fixed to. That is, through holes are formed in both the arc shield 4 and the support fitting 13, and the arc shield 4 is positioned by aligning the through holes. The arc shield 4 and the supporting bracket 13 are fixed by passing a rivet 14 through the through hole and caulking. The rest of FIG. 4 is the same as the configuration of FIG. Generally, since the fixing by the rivet 14 is generally stronger than the brazing, the fixing between the support fitting 13 and the arc shield 4 in FIG. 4 becomes stronger than in the conventional case.
The reliability of the vacuum valve is further improved.
