本発明は導波管のガスケットに関し、特にレーダ装置等
の電波応用機器において使用される導波管の接続におけ
るガスケットに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gasket for a waveguide, and particularly to a gasket for connecting waveguides used in radio wave application equipment such as radar equipment.
従来、この種の導波管の接続は、第４図に示すように導
波管４のフランジに加工された溝に０リング７を挿入す

れたガスケット９をフランジの間にはさむかして、それ
ぞれ数本のボルト５゜ナツト６で締付けることによって
気密構造になるように接続されていた。Conventionally, this type of waveguide was connected by inserting an O-ring 7 into a groove cut into the flange of the waveguide 4, as shown in FIG. 4, or by using an airtight seal as shown in FIG. A gasket 9 fitted with a gasket 8 was sandwiched between the flanges, and the flanges were connected to each other in an airtight structure by tightening them with several 5° nuts 6.
上述した従来の導波管の接続方法は、ねし類の締付けに
多くの時間を要するため、特に移動用の機材で、極力短
時間の野外設置が要求される場合、設置時間短縮に対し
て大きな障害となっていた。The conventional waveguide connection method described above requires a lot of time to tighten the wires, so it is difficult to reduce the installation time, especially when the equipment is mobile and requires outdoor installation in as short a time as possible. This was a major obstacle.
また、比較的細かな手先の作業であるため、寒い時期の
作業性を悪くしていた。In addition, since the work involved relatively detailed manual work, the workability during the cold season was worsened.
本発明はこれら従来の問題点を除去し、接続時間の短縮
化と接続の作業性改善を図った導波管のガスケットを提
供することを目的とする。It is an object of the present invention to provide a waveguide gasket which eliminates these conventional problems, reduces connection time, and improves connection workability.

等を使用する。In the second state, the gasket 2 attached to the gasket body 1
It is not crushed and the airtight structure is insufficient. Next, when the gasket body 1 is heated to a preset temperature using a heater such as a dryer, the gasket body 1 expands, and the gasket 2
By crushing it, it becomes an airtight structure and a sufficient connection is achieved. When disconnecting, conversely, the gasket body 1 is cooled to a preset temperature and contracted, resulting in the state shown in FIG. 2, which allows for easy disassembly. Note that a point cooler or the like is used as a cooling tool during cooling.
以上説明したように本発明は、ガスケット本体の素材と
して形状記憶合金を使用することにより。As explained above, the present invention uses a shape memory alloy as the material of the gasket body.
ねじを（吏用して接続する必要がなく、接続時間の短縮
と作業性の改善を実現できる効果を発揮する。There is no need to use screws to connect, which has the effect of shortening connection time and improving workability.
