構造体に関する。[Detailed description of the invention] [Field of industrial application] The present invention mainly relates to a composite packing structure that can maintain airtightness with a non-water-absorbing packing member and maintain watertightness with a rubber packing member that expands when water is absorbed. .
従来のパツキングは、一般的に弾性ゴムを２つ
の部材間に圧縮挟持してて圧縮時の弾性反発力に

いる。
In conventional packing, elastic rubber is generally compressed and sandwiched between two members to maintain airtightness and watertightness by the elastic repulsive force during compression.
しかし、従来のパツキングによれば、弾性ゴム

水密性および気密性が得られるものが求められて
いる。 However, according to conventional packing, the elastic repulsive force of elastic rubber is used to maintain watertightness and airtightness, so good effects are obtained only when the elastic rubber is compressed to near its elastic limit. There is an inconvenience that it cannot be done. In particular, electrical equipment such as switches is required to have a simple packing structure that provides good watertightness and airtightness.
このような事情から弾性ゴム単独のパツキング

いる。 Under these circumstances, a composite sealing material disclosed in, for example, Japanese Utility Model Application Publication No. 159099/1983 has been proposed in place of packing made of elastic rubber alone. This composite sealing material has a configuration in which a first member whose volume expands by absorbing moisture and a second member whose volume does not change even if it comes into contact with moisture are layered in a band shape,
A sealing effect is obtained by the expansion of the first member upon absorption of water.

は言うまでもない。 In this composite packing structure, the first and second rubber packing members with a circular cross section are arranged such that, for example, the connection piece protruding from the first rubber packing member with a circular cross section is connected to the center of the second rubber packing member with a circular cross section. The first rubber packing member with a circular cross section is placed on the side where moisture enters to ensure watertightness, and the second rubber packing member with a circular cross section is connected by being stretched and integrated. Airtightness is ensured by the elastic packing member. Of course, it goes without saying that the first and second circular cross-sectional rubber packing members complement each other in airtightness and watertightness.

Fig. 1 shows an embodiment in which the composite packing structure of the present invention is applied to a gas switch, and shows a case 1 (1a is an insulating part applied inside) in which an arc-extinguishing gas such as SF 6 is filled inside. , a fixed conductor 4 and a flexible conductor 5 connected to external cable conductors via bushings 2 and 3, a fixed electrode 6 (6a is the tip) provided at the tip of the fixed conductor 4, and a suction core 7.
The movable conductor 8 is connected to the flexible conductor 5, and the movable electrode 9 and the suction core 10 are provided at the tip of the movable conductor 8. Interlocking shaft 1
1, a movable insulator 14 that rotatably supports the movable conductor 8 by a pin 12, and forces the movable electrode 9 to open and close via a spring 13 by the rotation of the interlocking shaft 11; and the rotation of the interlocking shaft 11. a piston 16 which moves as a piston by receiving it via a link plate 15; and a puffer cylinder 17 which sucks and discharges arc-extinguishing gas by the movement of the piston 16.
and an arc extinguishing nozzle 18 fixed to the puffer cylinder 17. The movable electrode 9 provides an inter-electrode distance enlargement portion between it and the fixed electrode 6 by forming a tip portion 9a above the movable electrode 9. As described above, the movable insulator 14 is fixed to the interlocking shaft 11 and has a hole 14a at its tip through which the splint guide rod 19 is inserted, and the splint guide rod 19 has a stopper 19a at one end. The engagement between the link plate 15 and the piston 16 described above is based on the piston rod 16.
This is done by bringing the link plate 15 into contact with a pair of bearings 16c (in the figure, only one is visible because they overlap) that are rotatably supported by a piston 16b provided at the piston 16b. (Link board 15
has a bifurcated portion and straddles the piston rod 16a). Note that if the link plate 15 is integrally molded with the movable insulator 14 using epoxy resin, the structure is simple and electrical reliability can be improved.
