Consideration is required, and workability is extremely poor. Furthermore, since the operational vibrations of the shear break parts 1A to 1C are transmitted to the conductor 31 and amplified, the conductor insertion connection part 3
The amplitude at 2 becomes large and the contact becomes unstable.

下部が異方向に引出される場合についても同様の
配慮をなすことにより、本案の効果が維持できる
点は勿論である。 In addition, although we have explained here an example in which the upper and lower conductor connections of the three phases are drawn out in the same direction, the present proposal can also be achieved by taking the same consideration in the case where the lower part is drawn out in a different direction than the upper part. Of course, the effect can be maintained.

である。 Furthermore, although an example has been described in which the three phases are all connected together in the same direction and a single opening flange is provided for each phase, it is clear that the present invention can also be applied in cases in which each phase conductor from a three-phase container is connected in the same direction or in separate directions through separate openings.

以上３相一括形ガスしや断器に本案を適用した
場合について述べたがしや断器以外の密封電気機
器にも同様に適用できることは云うまでもない。 The case where the present invention is applied to a three-phase gas insulator or disconnector has been described above, but it goes without saying that it can be similarly applied to sealed electrical equipment other than insulators and disconnectors.

ある。(Effect of the invention) According to the present invention, since the plug-in connection part is attached to the equipment element body side and is arranged within a range smaller than the diameter of the bottom flange of the tank, it is possible to assemble the equipment element body and then The tank can be hung down, making it easy to assemble the device. Furthermore, even if the main body of the device element is vibrating, this vibration is absorbed by the plug-in connection, so that it is neither transmitted to the conductor nor amplified. Therefore, the contact is stable and no strain is applied to the insulating spacer. It has such practical effects.
