本発明はシーズヒータ端子部のガラス付は方法の改良に
関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the method of attaching glass to a sheathed heater terminal.
本発明者は先にシーズヒータ端子部に電気端子をガラス
コンパウンド層を介してガラス付けする方法を提案した
。The present inventor previously proposed a method of attaching an electric terminal to a sheathed heater terminal portion through a glass compound layer.
この方法は、まず第1図示のように、石英などからなる
シーズ管1の端子部2にマグネシア粉末などからなる骨
材層3を貫通して端子4を位置させ、上記骨材層3上に
粒状、粉状または液状のガラスろう5を供給する。In this method, first, as shown in the first diagram, a terminal 4 is placed on the terminal portion 2 of a sheath tube 1 made of quartz or the like by penetrating an aggregate layer 3 made of magnesia powder, etc., and then placed on the aggregate layer 3. Granular, powdered or liquid glass solder 5 is supplied.
ついで、第2図示のように、端子部2を加熱してガラス
ろう5を溶融し、骨材層3の上面から浸透させてガラス
コンパウンド層6を形成させるとともに端子4外面およ
び端子部2内面に溶着させる。Next, as shown in the second diagram, the terminal part 2 is heated to melt the glass solder 5 and permeate through the upper surface of the aggregate layer 3 to form a glass compound layer 6, and is applied to the outer surface of the terminal 4 and the inner surface of the terminal part 2. Weld.
そして冷却するとガラスろう5は固化し、第3図示のよ
うに、シーズ管1の端子部2にガラスコンパウンド層6
を介して端子4がガラス付けされる。When cooled, the glass solder 5 solidifies, and as shown in the third figure, a glass compound layer 6 is formed on the terminal portion 2 of the sheath tube 1.
The terminal 4 is attached to the glass via.
このような閉塞構造は、ガラスコンパウンド層6が熱的
および機械的衝撃に強い利点がある。Such a closed structure has the advantage that the glass compound layer 6 is resistant to thermal and mechanical shocks.
しかしながらその後、溶融ガラスろう5を骨材層3の表
面から浸透させる方法では、ガラスろう5の浸透に時間
がかかり、加熱時間が短いと上方部に余分のガラスろう
5が残り、歪みによるき裂が生じ易いなどの欠点がある
ことが判明した。However, in the method of infiltrating the molten glass solder 5 from the surface of the aggregate layer 3, it takes time for the glass solder 5 to penetrate, and if the heating time is short, excess glass solder 5 remains in the upper part, causing cracks due to distortion. It has been found that there are drawbacks such as easy occurrence of.
また、このガラス付けの加熱はシーズ管4の外側から行
われるのが普通で、電気端子4の下部の昇温かおくれ、
このためガラスろう5の浸透や濡れが不足がちとなり、
リークしたり、端子4の固定が不確実となるなどの欠点
が多発した。In addition, heating for this glass attachment is normally performed from the outside of the sheathed tube 4, so the heating of the lower part of the electrical terminal 4 is delayed, and
For this reason, penetration and wetting of the glass solder 5 tend to be insufficient.
There were many drawbacks such as leakage and unreliable fixing of the terminal 4.
さらに、シーズ管1に熱膨張率の小さな石英(a=5X
107/℃)や結晶化ガラス(a=11〜12X107
/’C)を用いた場合、このガラスコンパウンド層5と
シーズ管1端子部2との間に糸状組織をなすガラス層7
を設けて熱膨張差による破損を防止する必要があるが、
前述のような浸透方法では上層のガラスろうの密度がな
かなか下らないので、糸状組織の形成に時間がかかるほ
か、ややもすると糸状組織の形成が不充分となり、この
ためシーズ管4が破れることがあった。Furthermore, the sheath tube 1 is made of quartz with a small coefficient of thermal expansion (a=5X
107/℃) and crystallized glass (a=11~12X107
/'C), a glass layer 7 forming a filamentous structure between the glass compound layer 5 and the terminal portion 2 of the sheath tube 1
It is necessary to prevent damage due to thermal expansion difference by providing
In the penetration method described above, the density of the glass solder in the upper layer does not easily decrease, so it takes time to form a thread-like structure, and if the thread-like structure is formed insufficiently, the sheath tube 4 may break. Ta.
本発明はこのような先行技術の欠点を除くためになされ
たもので、端子のガラス付けが確実で、糸状組織の形成
も容易なガラス付は方法を提供することを目的とする。The present invention has been made in order to eliminate such drawbacks of the prior art, and aims to provide a method for attaching glass to a terminal in which the glass attachment is reliable and a thread-like structure can be easily formed.
本発明の要旨は始めガラスろうを端子表面におき、加熱
して溶融したガラスろうを周辺に向って浸透させてガラ
スコンパウンド層を形成させるとともにシーズ管端子部
内面に溶着させたことによって、従来よりも短時間でか
つ確実にガラス付けできるようにしたことである。The gist of the present invention is to first place a glass solder on the terminal surface, and then heat and melt the glass solder to permeate toward the periphery to form a glass compound layer and weld it to the inner surface of the sheathed tube terminal. This also made it possible to attach the glass reliably in a short period of time.
以下、本発明の詳細を第4図ないし第5図の実施例を参
照して説明する。The details of the present invention will be explained below with reference to the embodiments shown in FIGS. 4 and 5.
まず、第4図示のように、シーズ管1の端子部2にその
中心線に沿って少くともガラス付は予定部にガラスろう
5を被着した端子4を位置させ、この端子4の周囲に骨
材層3を密充填する。First, as shown in FIG. 4, a terminal 4 with a glass solder 5 coated at least in the intended portion with glass is positioned along the center line of the terminal portion 2 of the sheathed tube 1, and the terminal 4 is surrounded by a glass solder 5. The aggregate layer 3 is densely packed.
そして、第5図示のように、端子部2外面から加熱する
。Then, as shown in FIG. 5, heating is performed from the outer surface of the terminal portion 2.
すると、端子部2の熱は骨材層3を伝って端子4に達し
、この表面にあるガラスろう5を溶融し、周辺の骨材層
3中に浸透させ、かつ骨材層3外の端子4部分に被着し
たガラスろう6も端子4の昇温によって溶融させ、骨材
層3中に浸透させる。Then, the heat of the terminal part 2 reaches the terminal 4 through the aggregate layer 3, melts the glass solder 5 on the surface, penetrates into the surrounding aggregate layer 3, and causes the terminal outside the aggregate layer 3 to melt. The glass solder 6 adhered to the terminal 4 is also melted by increasing the temperature of the terminal 4, and penetrates into the aggregate layer 3.
そして、ガラスろう5が端子部2内面まで浸透したら加
熱を止めて冷却する。Then, when the glass solder 5 penetrates to the inner surface of the terminal part 2, heating is stopped and the terminal part 2 is cooled.
すると、第6図示のように、端子部2内面にガラスコン
パウンド層6を介して端子4がガラス付けされる。Then, as shown in FIG. 6, the terminal 4 is glass-bonded to the inner surface of the terminal portion 2 via the glass compound layer 6.
そして、シーズ管1が石英のように熱膨張率の小さなも
のであれば、端子部2内面とガラスコンパウンド層6と
の間に糸状組織をなすガラス層7が形成される。If the sheath tube 1 is made of a material having a small coefficient of thermal expansion, such as quartz, a glass layer 7 having a filamentous structure is formed between the inner surface of the terminal portion 2 and the glass compound layer 6.
本ガラス付は方法によれば、溶融ガラスろう5が中心部
にある端子4近傍から、より高温なシーズ管1端子部2
内面に向って浸透するので、従来よりも短時間でガラス
コンパウンド層が形成され、さらに、端子4の下側は予
めガラスろうを被着しであるので、濡れ不足によるリー
クや端子の固定不良などのおそれがない。According to this method, the molten glass solder 5 is moved from the vicinity of the terminal 4 in the center to the higher temperature sheath tube 1 terminal section 2.
Since it penetrates toward the inner surface, a glass compound layer is formed in a shorter time than before.Furthermore, since the lower side of the terminal 4 is coated with glass solder in advance, there is no possibility of leaks due to insufficient wetting or poor fixation of the terminal. There is no risk of
また、ガラスろう5の量は容易にコントロールでき、し
かも骨材層3上に層を作らないので、従来のようなガラ
スろう5のたまりが形成されることによるガラスコンパ
ウンド層6のき裂発生が防止される。In addition, the amount of glass solder 5 can be easily controlled, and since no layer is formed on the aggregate layer 3, cracks in the glass compound layer 6 due to the formation of pools of glass solder 5, as in the conventional case, are avoided. Prevented.
さらに、加熱時間の調整によって端子部近傍におけるガ
ラスろう5の量力相在に制御できるので、シーズ管が石
英のような熱膨張率の小さいものである場合、容易に糸
状組織をなすガラス層7が形成できる。Furthermore, by adjusting the heating time, it is possible to control the amount and strength of the glass solder 5 in the vicinity of the terminal, so if the sheath tube is made of a material with a low coefficient of thermal expansion such as quartz, the glass layer 7, which easily forms a filamentous structure, can be controlled. Can be formed.
つぎに具体例をあげて詳述する。Next, a specific example will be given and explained in detail.

これより上方の部分台せて15mm

0.5m+++被覆した。Terminal 4: Iron-nickel alloy round bar glass solder with a diameter of 2 wrL 5: The terminal 4 with glass is attached to the planned part and the part above this within a range of 15 mm Pbo B2O3S io 2 series glass (softened (temperature: 354°C) was coated to a thickness of 0.5m+++.
このような部材を前述のようにしてガラス付けしたとこ
ろ、従来、加熱に1.5分ないし2分を必要としたのが
、1分以下で充分になり、厚さ約10wrLのガラスコ
ンパウンド層6と糸状組織をなすガラス層7とが形成さ
れた。When such a member was glass-attached as described above, heating, which conventionally required 1.5 to 2 minutes, was completed in less than 1 minute, and the glass compound layer 6 with a thickness of about 10 wrL was heated. A glass layer 7 having a filamentous structure was formed.
このものは0℃と300℃との冷熱サイクルに充分耐え
られた。This product could sufficiently withstand cooling and heating cycles from 0°C to 300°C.
端子にガラスろうを被着する方法は溶融ガラス液に端子

焼き付ける方法など、従来既知の方法でよく、かつその
被着量はガラスろうを浸透させたい範囲やガラス層に糸
状組織を形成させるか否かなどにより選定する。The glass solder can be applied to the terminal by any conventionally known method, such as immersing the terminal in molten glass liquid and pulling it up, or applying glass powder to the terminal and baking it. The selection is made depending on the area to be penetrated and whether or not a filamentous structure is to be formed in the glass layer.
一般に、石英シーズ管など、糸状組織のガラス層を必要
とし、密封を要しない場合はガラスろうの被着量を少<
シ、金属シーズ管など完全密封を必要とする場合は多め
にする。In general, if a filamentous glass layer is required, such as in a quartz sheathed tube, and sealing is not required, the amount of glass solder deposited is small.
If complete sealing is required, such as a metal sheathed pipe, use more.
そして、ガラスろうの被着厚さは1m以下にすることが
好ましく、これより厚いと形成されたガラスコンパウン
ド層と端子との間に間隙が形成されて好ましくない。The thickness of the glass solder to be applied is preferably 1 m or less; if it is thicker than this, a gap will be formed between the formed glass compound layer and the terminal, which is not preferable.

The glass solder is heated to melt the glass solder and permeate into the surrounding aggregate layer to form a glass compound layer, and is also welded to the inner surface of the terminal portion.
Glass solder penetrates into the aggregate layer more quickly and uniformly than before, and depending on the combination of materials between the sheath tube and the aggregate, the glass layer between the sheath tube and the glass compound layer can be easily and reliably formed into filaments. There are advantages to the organization.
