つてセンサーのリード線を容器外に取り出して測
定器等に接続する場合、リード線の取り出しによ
つて容器の気密性が損なわれることのないように
しなければならない。 For example, sensors such as the detection coil of a magnetic probe are housed in a sealed container that is under high pressure or vacuum relative to the outside air, so the sensor lead wire must be taken out of the container. When connecting to a measuring instrument, etc., care must be taken to ensure that the airtightness of the container is not compromised by removing the lead wire.
そこでリード線を金属製の導出管内に収納し、
この導出管を容器の取出し孔部分に溶接すること

た。 Therefore, the lead wire is stored in a metal lead-out pipe,
A possible means of maintaining airtightness is to weld this outlet pipe to the outlet hole of the container, but this welding is, for example, brazing, and the heat during this welding process is applied to the lead wire inside the outlet pipe. It was passed down,
There was a risk of damaging the lead wire and insulation tube.
本考案は上述した従来の欠点、不都合を解消す

密に嵌め込み溶着する構成である。 The present invention relates to a lead wire outlet tube extraction structure devised to eliminate the above-mentioned conventional drawbacks and inconveniences. A sealing fitting having an inner diameter sufficiently larger than the outer diameter of the lead-out pipe to which the lead-out pipe is welded airtightly through the axial center position,
It is configured to be tightly fitted and welded.
以下本考案の一実施例を図面に従つて説明す

取出し孔２内には取出し筒３が貫通設されてい
る。 First of all, in Fig. 1, numeral 1 is a sealed container,
A take-out hole 2 is bored in a part of the wall, and a take-out tube 3 is passed through the take-out hole 2.
取出し筒３は容器１に例えばろう付溶接によつ
て気密に固定されており、容器１外方に突出した
先端には鍔板４が外周設されている。 The take-out tube 3 is airtightly fixed to the container 1 by, for example, brazing welding, and a flange plate 4 is provided on the outer periphery of the tip of the container 1 that projects outward.
また５は所定の保護被覆がなされた検出コイル

筒３を貫通して外部に引き出される。 Reference numeral 5 denotes a sensor such as a detection coil with a predetermined protective coating, and a metal lead wire lead-out pipe 6 in which a lead wire is housed is continuous from this sensor 5. passes through the take-out tube 3 and is drawn out to the outside.
前記取出し筒３の先端には、金属製の蓋板７
が、後述する全ての作業が終了した段階で鍔板４
に貼り合わされる形態で容器１の気密を確保する
べく溶接固定されるが、この蓋板７の中心には前
記導出管６を引き出すための引出し孔８が穿たれ
ている。 A metal lid plate 7 is provided at the tip of the extraction cylinder 3.
However, when all the work described below is completed, the flange plate 4
The lid plate 7 is welded and fixed to ensure airtightness of the container 1, and a draw-out hole 8 is bored in the center of the lid plate 7 for pulling out the lead-out tube 6.
この引出し孔８内には、第２図に示すように金
属製円筒形状のスリーブ９がぴつたりと嵌め込ま
れ、ろう付け溶接Ｗ−２により密に固定されてい
る。 As shown in FIG. 2, a metal cylindrical sleeve 9 is tightly fitted into the pull-out hole 8 and tightly fixed by brazing welding W-2.
一方前記導出管６にあつての所定位置には、シ
ール金具１０が予め周設固定される。 On the other hand, a seal fitting 10 is circumferentially fixed in advance at a predetermined position on the outlet pipe 6.
このシール金具１０は、内径が導出管６の外径
よりも十分に大きく、外径が前記スリーブ９の内
径と等しい金属製の円筒形状であるが、開口した
一端に対して他端には端板１１が一体設され、さ
らにこの端板１１の中心には内径が導出管６の直
径と等しい嵌込管１２が軸心上に一体突設されて
いる。 The seal fitting 10 has a cylindrical shape made of metal whose inner diameter is sufficiently larger than the outer diameter of the outlet pipe 6 and whose outer diameter is equal to the inner diameter of the sleeve 9. A plate 11 is integrally provided, and a fitting tube 12 having an inner diameter equal to the diameter of the outlet tube 6 is integrally provided at the center of the end plate 11 and protrudes from the center thereof.
そして、リード線が収納される前の段階で、導
出管６をこの嵌込管１２からシール金属１０に貫
通させ、嵌込管１２と密に溶接Ｗ−１するのであ
る。 Then, before the lead wire is housed, the lead-out tube 6 is passed through the fitting tube 12 into the seal metal 10 and tightly welded to the fitting tube 12 W-1.
さて、このような構成にあつて、導出管６を前
述した蓋板７のスリーブ９内を貫通させ、さらに
このスリーブ９内に前記シール金具１０を嵌め込
み、シール金具１０の開口した一方端をスリーブ
９の開口端と密に溶接Ｗ−３する。 Now, in such a configuration, the outlet pipe 6 is passed through the sleeve 9 of the cover plate 7 described above, and the seal fitting 10 is further fitted into the sleeve 9, and one open end of the seal fitting 10 is inserted into the sleeve 9. Weld W-3 tightly to the open end of No.9.
以上の説明から明らかなように、本考案は、容
器１の蓋板７に対して、リード線導出管６は、ス
リーブ９とシール金具１０を介して貫通固定され
て外部に引き出される構成であり、しも各部材は
溶接によりシールされて接続固定されているの
で、リード線導出管６を引き出すにも拘らず容器
１の気密性を確保することができる。 As is clear from the above description, in the present invention, the lead wire lead-out tube 6 is fixed through the lid plate 7 of the container 1 via the sleeve 9 and the seal fitting 10 and is drawn out. Since each member is sealed and connected and fixed by welding, the airtightness of the container 1 can be ensured even though the lead wire outlet pipe 6 is pulled out.
また溶接作業において、導出管６とシール金具
１０との溶接は、リード線が導出管６に収納され

響を及ぼすおそれはなく、シール金具１０とスリ
ーブ９との溶接も、シール金具１０の内径が導出
管６の直径よりも十分に大きく従つて間隔があい
ており、且つシール金具１０の開口一方端で行な
われるので、溶接熱が直接にリード線に伝達され
ることはない。 Further, in the welding work, welding between the lead pipe 6 and the seal fitting 10 is performed before the lead wire is stored in the lead pipe 6, so there is no risk of welding heat having a negative effect on the lead wire, and the seal fitting 10 and the lead wire are welded together. The welding with the sleeve 9 is also carried out at one end of the opening of the seal fitting 10 because the inner diameter of the seal fitting 10 is sufficiently larger than the diameter of the outlet pipe 6 and there is a gap therebetween, so that the welding heat is directly led. It is not transmitted to the line.

る。 Therefore, according to the lead wire outlet tube extraction structure of the present invention, the lead wire outlet tube can be pulled out while ensuring the sealing performance of the container housing the sensor.
It has many excellent functions and effects, such as the fact that welding heat does not adversely affect the lead wire during sealing work by welding, the structure is simple, and the work is easy.
