その酸化被膜或は塵埃の為金属間の接合をせず、
従つて外部より補強的にハンダを施しても猶ガス
漏れ等を生じた。 Conventionally, as shown in Fig. 1, the gas sealing method for this type of temperature-sensing tube is to press the vicinity of the tip of the temperature-sensing tube 1 using a chip (not shown) 2, heat it from the outside, and apply solder 3, etc. However, if the copper or other metal that makes up the thermosensor is oxidized or has dust attached to it, the oxide film or dust may be removed even if the area near the tip is pressed. Therefore, there is no joining between metals,
Therefore, even if soldering was applied from the outside for reinforcement, gas leakage still occurred.

るようにした感温筒のガス封止方法にある。 The present invention is a sealing method invented in view of the above points, and according to the present invention, after filling the temperature sensing cylinder with gas, a sealing material such as a solder material is inserted into the temperature sensing cylinder, Furthermore, the temperature-sensitive cylinder is temporarily sealed with this sealing material in place, and then the temperature-sensitive cylinder is heated from the outside to melt the sealing material inside, and the temporarily sealed part is completely sealed with this molten sealing material. The problem lies in the gas sealing method of the thermosensor cylinder.

しめる。 According to the present invention, a temperature-sensitive cylinder made of copper or the like is first evacuated and a gas such as freon is filled inside, and the vicinity of the tip is crimped and sealed using an appropriate tool, and the first temporary Molding the sealing part. Since a space is formed between the first temporary sealing part and the tip end, a suitable sealing material such as a solder material is inserted into this space. After inserting the sealing material, use an appropriate tool to crimp the portion including the tip of the temperature-sensitive tube and the portion closer to the tip.
A second temporary sealing section is formed, and the sealing material is positioned in a space between the first temporary sealing section and the second temporary sealing section.
このような状態で前記空所を外部より加熱する
ことにより空所内の封止材を溶融し、第２の仮封
止部を内方より覆う。 In this state, the cavity is heated from the outside to melt the sealing material in the cavity and cover the second temporary sealing part from the inside.
このようにする時は第２の仮封止部は内部の封

存在する形となる。 After evacuating the temperature-sensitive cylinder 10 made of copper and filling it with a gas such as Freon, the area near the tip is crimped at approximately 20 kg using an appropriate tool as shown at 11 to form a first temporary sealing part. , the void at the tip created by this 1
Insert silver solder 13 into 2. After doing this,
Using an appropriate tool, cut the tip 14 of the thermosensor tube approximately
The second temporary sealing portion 15 is formed by pressing with 10 kg and crushing it flat. Therefore, the silver solder 13 is present in the space 12 between the first temporary sealing part 11 and the second temporary sealing part 15.
