Description

【０００１】
【発明の属する技術分野】
本発明は、シース熱電対、シース測温抵抗体、あるいは被覆電線等の金属製又は非金属製の被覆部材を有するケーブルを固定体に支持部材を介して固定するケーブル固定方法に関する。
【０００２】
【従来の技術】
上記ケーブルのうちのシース熱電対を例に挙げて説明すれば、例えば本願発明の図１に示すように、シース熱電対１の先端に備える温接点７を固定体であるウエハー２に形成の凹部２Ａ内にセラミックセメント等の接着材料８により埋設するのである。図１では１箇所のみ図示しているが、ウエハー２の任意の箇所（複数箇所）に前記のように温接点７を埋設し、このように複数箇所に温接点が埋設されたシース熱電対１の複数本を纏めてウエハー２に固定することが行われている。
そして、従来、図１０に示すように、前記シース熱電対１と同一のシース熱電対３４（支持の構成が異なるため、従来例で示しているシース熱電対の番号と図１の本願発明のシース熱電対の番号とを異ならせている）の複数本（図では３本）を支持部材３０を介してウエハー２に固定するようにしている（図では１箇所の固定構造しか示していないが、実際にはシース熱電対の配設方向複数箇所で固定することになる）。詳述すれば、ウエハー２に貫通孔を形成し、この貫通孔に棒状体３１を挿入した後、両側から円板３２，３３を当て付けた状態で各円板３２，３３を棒状体３１に溶接により固定する。次に、薄い板状の支持部材３０の一端側を前記円板３２の上面にスポット溶接等により固定した後、支持部材３０の中間部を複数のシース熱電対３４…に巻き付けた状態で支持部材３０を折り曲げるとともに、折り曲げて前記支持部材３０の一端側に重なり合った他端側をスポット溶接等により固定することによって、複数のシース熱電対３４をウエハー２に固定できるようにしている。
【０００３】
上記従来の固定方法によれば、支持部材３０を複数のシース熱電対３４…にただ単に巻き付けているだけであるため、支持部材３０の内面とシース熱電対３４…の外面との摩擦力によりシース熱電対３４…の長手方向の移動を完全に阻止することができない。従って、例えばシース熱電対３４の先端の温接点（図示していないが、温接点の埋設構造は本願発明の図１と同一構成である）とこの温接点に最も近い支持部材３０との間でシース熱電対３４が温接点から遠ざかる側へ移動するようなことがあると、温接点がウエハーの凹部から離脱したり、特に径の細いシース熱電対３４にあっては断線することもあった。
前記の場合には、温接点が引っ張り力を受けた場合であるが、これとは逆に温接点側にシース熱電対３４が送り出されることにより、シース熱電対３４が温接点とこの温接点に最も近い支持部材３０との間で弛んだ場合には、シース熱電対３４が不測に浮き上がり、他物と接触して、計測上好ましくない不都合が発生するだけでなく、他物が引っ掛かることにより引っ張り力が温接点に作用することにより、前記同様の不都合を招くものであった。
【０００４】
上記不都合を解消するために、例えば支持部材３０によるシース熱電対３４の巻き付け力を増大させることが考えられるが、設定値以上の巻き付け力をシース熱電対３４に付与すると、シース熱電対３４が横に拡がったり、長手方向に伸びたりして、シース熱電対自体が変形してしまうため、その部分での電気的特性が変更されてしまうことがあり、前記巻き付け力を不用意に大きくすることができないものであり、改善の余地があった。
【０００５】
【発明が解決しようとする課題】
本発明が前述の状況に鑑み、解決しようとするところは、電気的特性が変更されてしまうことがない状態で、ケーブルを固定体へ確実に固定することができるケーブル固定方法を提供する点にある。
【０００６】
【課題を解決するための手段】
本発明は、前述の課題解決のために、シース熱電対、シース測温抵抗体、あるいは被覆電線等の金属製又は非金属製の被覆部材を有するケーブルを固定体に支持部材を介して固定するケーブル固定方法であって、前記支持部材に形成の貫通孔又は切欠部にてケーブルを挿通保持した状態で該支持部材を、それの貫通孔位置又は切欠部位置で、かつ、ケーブル挿通方向と交差する方向を折り目にして折り曲げることにより、該ケーブルを屈曲させ、この状態で該支持部材を前記固定体に固定するのである。
又、シース熱電対、シース測温抵抗体、あるいは被覆電線等の金属製又は非金属製の被覆部材を有するケーブルを固定体に支持部材を介して固定するケーブル固定方法であって、前記支持部材が、長手方向２箇所に貫通孔が形成された前後方向に長い平板状の部材でなり、この支持部材の板厚方向が上下となる状態で前記２つの貫通孔間の平板部の２箇所で、かつ、該支持部材の長手方向と交差する方向を折り目にして該支持部材の長手方向両側をほぼ同一設定角度下方に折り曲げ、その折り曲げられた支持部材の両側部に位置する前記２つの貫通孔にケーブルを挿通した状態で該支持部材を、それら２つの貫通孔位置で、かつ、ケーブル挿通方向と交差する方向を折り目にして上方に設定角度それぞれ折り曲げることにより、該ケーブルを前記貫通孔２箇所で屈曲させ、この状態で該支持部材を前記固定体に固定してもよい。
又、シース熱電対、シース測温抵抗体、あるいは被覆電線等の金属製又は非金属製の被覆部材を有するケーブルを固定体に支持部材を介して固定するケーブル固定方法であって、前記支持部材が、長手方向２箇所に幅方向一側から切り欠いた切欠部が形成された前後方向に長い平板状の部材でなり、この支持部材の板厚方向が上下となる状態で前記２つの切欠部間の平板部の２箇所で、かつ、該支持部材の長手方向と交差する方向を折り目にして該支持部材の長手方向両側をほぼ同一設定角度下方に折り曲げ、その折り曲げられた支持部材の両側部に位置する前記２つの切欠部にケーブルを該支持部材の幅方向一側から差し込んだ状態で該支持部材を、それら２つの切欠部位置で、かつ、ケーブル挿通方向と交差する方向を折り目にして上方に設定角度それぞれ折り曲げることにより、該ケーブルを前記切欠部２箇所で屈曲させ、この状態で該支持部材を前記固定体に固定してもよい。
上記３つの方法のいずれにおいても、支持部材を屈曲させることを利用して、ケーブルを屈曲させるのである。これは、ケーブルが本来的に屈曲することができる性質を利用したものであり、ケーブルの屈曲部分における電気的性質が変化することがないのである。そして、ケーブルが長手方向に移動するためには、ケーブルが一旦一直線状に変形する必要性があるが、上記のようにケーブルの１箇所又は２箇所で屈曲させることによりケーブルが一直線状となることが阻止され、ケーブルが長手方向に移動することができないものである。この場合、１箇所よりも２箇所で屈曲させる方がケーブルの移動をより効果的に阻止することができる。又、ケーブルを挿通させるための貫通孔を切欠部に構成することによって、切欠部にケーブルを挿通させる時期を自由に変更しても差し支えない。
【０００７】
前記支持部材をそれの上方から押し潰すことによって、該支持部材が保形強度の弱い貫通孔位置又は切欠部位置で自ずと折り曲がり、ケーブルを屈曲させることができるのである。前記支持部材をそれの上方から押し潰す場合には、例えばハンマー等で支持部材を叩いたり、機械等により動力を用いた他の方法で押し潰すようにしてもよい。
【０００８】
前記支持部材の２箇所に形成した切欠部の開放端の一方を、該支持部材の幅方向一側に形成し、かつ、他方の開放端を該支持部材の幅方向他側に形成することによって、２つの切欠部の開放端を同一側にした場合に比べて、切欠部に挿通したケーブルが切欠部の開放端から外れ難くすることができ、前記支持部材の屈曲作業を容易に行うことができる。
【０００９】
【発明の実施の形態】
図１及び図２に、シース熱電対１（ケーブル）がシリコンや透明又は不透明な石英等からなるウエハー（固定体）２に固定された状態を示している。この実施例では、シース熱電対１についてのみ説明するが、シース測温抵抗体やその他の金属製又は非金属製の被覆部材を有するケーブルをウエハー（固定体）２に固定する場合も本発明は適応することができる。又、固定体としてウエハー２の他、木製や金属製、あるいは合成樹脂製等で構成された構造物であってもよいし、又、各種装置を固定体としてケーブルを各種装置に固定するようにしてもよい。
【００１０】
前記シース熱電対１は、図７にも示すように、保護外被としてのシース３の内部に絶縁粉末としてマグネシア（ＭｇＯ）４を充填し、そのマグネシア（ＭｇＯ）４内に一対の素線５，６を配設して構成されている。
【００１１】
次に、前記シース熱電対１をウエハー２に固定する固定方法について説明する。
まず、前記素線５，６の先端部に接合された温接点７をウエハー２に形成の凹部２Ａ内に配置させるようにシース熱電対１を送り出す。この後、凹部２Ａ内にセラミックセメント等の接着材料８を充填することにより、温接点７を凹部２Ａ内に固定（埋設）するのである。
次に、前記シース熱電対１の適当箇所を支持部材９を介してウエハー２に固定することによって、支持部材９と前記固定（埋設）された温接点７との間でシース熱電対１が移動することがないようにしている。
詳述すれば、図１及び図２に示すように、金属製の円板１０の下面に金属製の棒状部１１を溶接してなる鋲１２を予め用意し、この鋲１２の棒状部１１をウエハー２に形成の貫通孔２Ｂに上方（ウエハー２の表面側）から差し込んだ後、貫通状態の棒状部１１の下面にウエハー２の裏面側から前記円板１０と同一の円板１３を当て付けた状態で溶接により固定し、前記上方に位置する円板１０の上面に前記複数本のシース熱電対１…が支持された金属製の支持部材９の４隅をスポット溶接により固定するのである。図２に示すＳが、溶接箇所を示している。前記支持部材９により４本のシース熱電対１…を支持した場合を示したが、１本、２本、３本、５本以上のどの本数でもよい。
【００１２】
前記複数本（この実施例では４本を示している）のシース熱電対１…を支持部材９に支持させる支持方法について説明すれば、まず図３（イ）に示すような一対の貫通孔９ａ，９ｂが形成された平板状の部材からなる前記支持部材９を用い、図に示すように板厚方向が上下となる状態で２つの貫通孔９ａ，９ｂ間の平板部（中間部）９Ｃのうちの貫通孔９ａ，９ｂ側の端部の２箇所で、かつ、支持部材９の長手方向と交差する方向（この実施例では直交する方向）を折り目９Ｋ，９Ｋにして、支持部材９の長手方向両側を下方に折り曲げる（図３（ロ）参照）。尚、この折り曲げられた支持部材９の両側部９Ａ，９Ｂは、水平面に対して約６０度下方に傾斜した姿勢になっているが、この角度を、５度〜９０度の間の角度であればどのような角度に設定してもよい。
次に、折り曲げられた支持部材９の両側部９Ａ，９Ｂに位置する貫通孔９ａ，９ｂに、例えば一方の貫通孔９ａから他方の貫通孔９ｂに複数本のシース熱電対１…を挿通する（図３（ハ）参照）。このように支持部材９の長手方向両側のそれぞれを下方にほぼ同一角度折り曲げることによって、一方の貫通孔９ａから他方の貫通孔９ｂに一直線状のシース熱電対１…を図に示すように挿通する際の挿通可能な貫通孔９ａ，９ｂの上下寸法をほぼ同一にすることができる。この後、支持部材９の平板部（中間部）９Ｃを上方から図に示す外力Ｆを与えることにより図３（ニ）に示すように、支持部材９を押し潰すことで、支持部材９の両側部９Ａ，９Ｂが保形強度の最も弱い貫通孔９ａ，９ｂ位置で折り曲げられるのである。図の９Ｈ，９Ｈが折り目を示している。図では、シース熱電対１…の外形寸法よりも貫通孔９ａ，９ｂの上下寸法を大きく設定することによって、貫通孔９ａ，９ｂへのシース熱電対１…の挿入の容易化を図ることができるが、シース熱電対１…を貫通孔９ａ，９ｂに挿入することができるように、シース熱電対１…の外形寸法と貫通孔９ａ，９ｂの上下寸法とをほぼ同一に設定して実施してもよい。このように貫通孔９ａ，９ｂの上下寸法を設定することによって、後述のようにシース熱電対１…を屈曲させたときの屈曲角度を大きくして、シース熱電対１…が貫通孔９ａ，９ｂに対してより移動し難くすることができる。又、前記貫通孔９ａ，９ｂから折り目９Ｋ，９Ｋまでの距離それぞれを同一にすることによって、折り目９Ｋ，９Ｋで折り曲げられた両側部９Ａ，９Ｂに位置する２つの貫通孔９ａ，９ｂを上下同一高さ位置にすることができ、図のようにシース熱電対１…を水平方向の状態で容易に貫通孔９ａ，９ｂに貫通させることができるようにしているが、前記２つの距離を異ならせて実施することもできる。又、前記折り目９Ｈ，９Ｈも前記折り目９Ｋ，９Ｋと同様に同一箇所に設けたが、異なる箇所に設けてもよい。
このように支持部材９を押し潰すことによって、シース熱電対１…を貫通孔２箇所で屈曲させ、この状態で前述のように支持部材９の４隅を円板１０の上面にスポット溶接により固定して、シース熱電対１が長手方向に移動することを確実に阻止することができるようにしている。前記支持部材９の両側部９Ａ，９Ｂを貫通孔９ａ，９ｂ位置、つまり折り目９Ｈ，９Ｈで折り曲げることによって、図４（イ）に示す貫通孔９ａ，９ｂの上下寸法Ｘが図４（ロ）に示すように短くなった上下寸法Ｙになっている。これは、貫通孔９ａ，９ｂの下側が水平方向に移動することにより貫通孔９ａ，９ｂの上下寸法が短くなっている。尚、支持部材９が折り曲げられる箇所は、支持部材９を押し潰すことで、保形強度の最も弱い下端側の箇所になるが、支持部材９を押し潰すのではなく、支持部材９を折り曲げることにより、その折り曲げ箇所を貫通孔９ａ，９ｂのどの箇所にも設定することができるが、貫通孔９ａ，９ｂの上方側に位置するほど貫通孔９ａ，９ｂの上下寸法が短くなり、シース熱電対１に対する挟圧力が増してくることになる。前記支持部材９を板厚１ｍｍ以下のアルミニウム等の比較的柔らかい材質の金属で形成することによって、支持部材９を容易に押し潰して支持部材９の折り曲げを容易にすることができる利点があるが、その他の金属製材料の他、樹脂を軟化温度以上に加熱することにより折り曲げ変形する場合でもよい。
【００１３】
前記実施例では、支持部材９に貫通孔９ａ，９ｂを形成したが、図５（イ）に示すように、シース熱電対１…を支持部材９の幅方向一側から差し込み可能な切欠部１４，１５を形成してもよい。これら切欠部１４，１５は、開放側端部側にシース熱電対１…を差し込み可能な程度の幅の大きさに形成された挿入部１４Ａ，１５Ａと、これよりも幅が広く、かつ、図６に示すように支持部材９をウエハー２に固定するためのステンレス製の止め金具１６を挿入可能なシース熱電対１…保持部１４Ｂ，１５Ｂとから構成している。このような切欠部１４，１５の場合には、シース熱電対１…を支持部材９の幅方向一側から差し込むだけで支持部材９にシース熱電対１…を支持させることができるから、前述のように支持部材９の貫通孔９ａ，９ｂに挿通させるものに比べて作業を容易迅速に行えるのである。
次に、図５（イ）に示す支持部材９にシース熱電対１…を支持させた後、ウエハー２に固定する場合について説明する。まず、図５（イ）に示す折り目９Ｋ，９Ｋで支持部材９の両側をそれぞれ前述のように折り曲げた後、図５（ロ）に示すように、平板状の支持部材９の保持部１４Ｂ，１５Ｂ内にそれぞれ、両端部１６Ａ，１６Ａが丸く屈曲形成された止め金具１６の中間部が位置するように止め金具１６を配置した後、図５（ハ）に示すように、複数本のシース熱電対１…を挿入部１４Ａ，１５Ａから保持部１４Ｂ，１５Ｂ内に配置し、前述のように切欠部１４，１５の任意の箇所、つまり図に示す折り目９Ｈ，９Ｈで支持部材９をそれの長手方向と交差する方向に折り曲げることによって、シース熱電対１…を屈曲させることができるようにしている。この後、止め金具１６，１６それぞれの両端部１６Ａ，１６Ａを、図６に示すように、ウエハー２に形成の凹部１７，１７内に挿入し、この状態でセラミックセメント等の接着剤１８を凹部１７，１７に充填することにより金具１６，１６をウエハー２に固定して、支持部材９をウエハー２に固定できるようにしている。
【００１４】
前記支持部材９を、図８に示すように構成してもよい。つまり、前記切欠部１４，１５の挿入部１４Ａ，１５Ａのうちの一方の挿入部１４Ａの開放端を支持部材９の幅方向一側に形成し、かつ、他方の挿入部１５Ａの開放端を支持部材９の幅方向他側に形成することによって、前記のように同一側に形成した場合に比べて支持部材９から差し込んだシース熱電対１…が抜け難くすることができるのである。
【００１５】
前記実施例では、支持部材９の２箇所を折り曲げるようにしたが、図９に示すように、支持部材９をそれに形成の孔９ａの任意の箇所の１箇所のみを折り曲げることによりシース熱電対１…を１箇所でのみ屈曲させて、ウエハー２に固定するようにしてもよい。前記孔９ａは貫通孔又は切欠部のいずれに形成してもよい。前記支持部材９をウエハー２に固定する構成は、前述と同様であるため、説明を省略する。
【００１６】
【発明の効果】
請求項１のように、屈曲するというケーブルが本来的に有している性質を利用することによって、従来のように電気的特性が変更されるような状態が発生することなく、確実にケーブルを固定体に固定することができ、長期間に渡って良好に使用することができるケーブル固定方法を提供することができる。
しかも、支持部材を折り曲げることを利用してケーブルを屈曲させることができるから、ケーブルを配設する際に任意の位置でケーブルを屈曲させることができる。
又、支持部材を折り曲げる位置を貫通孔又は切欠部のどの位置に設定するかによって、ケーブルの挟圧力を変更することができる利点もある。
又、切欠部である場合には、貫通孔のように支持部材の取付順序を考慮する必要がなく、最後に支持部材を取り付けることができる等、貫通孔に比べて作業の融通性を図ることができるだけでなく、支持部材の幅方向一側から差し込むことによりケーブルを支持させることができる作業性の向上を図ることができる。
【００１７】
請求項３及び請求項５のように、ケーブルを貫通孔２箇所又は切欠部２箇所で屈曲させることによって、１箇所でのみ屈曲させるものに比べてケーブルを固定体に強固に固定することができる利点がある。
【００１８】
請求項７のように、２つの切欠部の開放端の位置を支持部材の幅方向両側にそれぞれ振り分けて形成することによって、切欠部からケーブルを抜け難くすることができ、長期間に渡って良好に支持部材による支持を可能にすることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a cable fixing method for fixing a cable having a metallic or non-metallic covering member such as a sheathed thermocouple, a sheathed resistance temperature detector, or a covered electric wire to a fixed body via a support member.
[0002]
[Prior art]
For example, as shown in FIG. 1 of the present invention, a concave portion formed in a wafer 2 as a fixed body with a hot junction 7 provided at the tip of the sheath thermocouple 1 will be described. 2A is embedded with an adhesive material 8 such as ceramic cement. Although only one location is illustrated in FIG. 1, the sheath thermocouple 1 in which the hot junction 7 is embedded in an arbitrary location (a plurality of locations) of the wafer 2 as described above and the hot junction is embedded in a plurality of locations as described above. A plurality of these are collectively fixed to the wafer 2.
Conventionally, as shown in FIG. 10, the same sheathed thermocouple 34 as the sheathed thermocouple 1 (the support configuration is different, so the number of the sheathed thermocouple shown in the conventional example and the sheath of the present invention in FIG. 1). A plurality (three in the figure) of the thermocouples are fixed to the wafer 2 via the support member 30 (only one fixing structure is shown in the figure, Actually, the sheath thermocouple is fixed at a plurality of locations in the arrangement direction). More specifically, after a through hole is formed in the wafer 2 and the rod-shaped body 31 is inserted into the through-hole, the disks 32 and 33 are attached to the rod-shaped body 31 with the disks 32 and 33 being applied from both sides. Secure by welding. Next, after fixing one end side of the thin plate-like support member 30 to the upper surface of the disk 32 by spot welding or the like, the support member 30 is wound around the plurality of sheathed thermocouples 34. The plurality of sheathed thermocouples 34 can be fixed to the wafer 2 by bending the wire 30 and fixing the other end of the support member 30 that is overlapped with the one end of the support member 30 by spot welding or the like.
[0003]
According to the above conventional fixing method, the support member 30 is simply wound around the plurality of sheath thermocouples 34. Therefore, the sheath member is caused by the frictional force between the inner surface of the support member 30 and the outer surface of the sheath thermocouple 34. The movement of the thermocouples 34 in the longitudinal direction cannot be completely prevented. Therefore, for example, between the hot junction at the tip of the sheath thermocouple 34 (not shown, but the buried structure of the hot junction is the same as that of FIG. 1 of the present invention) and the support member 30 closest to the hot junction. If the sheath thermocouple 34 moves away from the hot junction, the hot junction may detach from the concave portion of the wafer, or the sheath thermocouple 34 with a small diameter may break.
In the above case, the hot junction is subjected to a tensile force. Conversely, when the sheath thermocouple 34 is sent out to the hot junction side, the sheath thermocouple 34 is connected to the hot junction and the hot junction. If the sheath thermocouple 34 is loosened with the nearest support member 30, the sheath thermocouple 34 unexpectedly floats and comes into contact with another object, causing not only an unfavorable inconvenience in measurement, but also pulling because the other object is caught. When the force acts on the hot junction, the same disadvantages as described above are caused.
[0004]
In order to solve the above inconvenience, for example, it is conceivable to increase the wrapping force of the sheath thermocouple 34 by the support member 30. However, when a wrapping force equal to or greater than a set value is applied to the sheath thermocouple 34, the sheath thermocouple 34 is laterally moved. The sheath thermocouple itself is deformed by spreading in the longitudinal direction or extending in the longitudinal direction, and the electrical characteristics at that portion may be changed, and the winding force may be increased carelessly. There was room for improvement.
[0005]
[Problems to be solved by the invention]
In view of the above-described situation, the present invention intends to provide a cable fixing method capable of reliably fixing a cable to a fixed body in a state where electrical characteristics are not changed. is there.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention fixes a cable having a metal or non-metal covering member such as a sheathed thermocouple, a sheathed resistance temperature detector, or a covered electric wire to a fixed body via a support member. A cable fixing method, wherein a cable is inserted and held in a through hole or notch formed in the support member, and the support member is crossed with the through hole position or notch position of the support member. The cable is bent by bending the direction to be folded, and the support member is fixed to the fixed body in this state.
Also, a cable fixing method for fixing a cable having a metallic or non-metallic covering member such as a sheathed thermocouple, a sheathed resistance temperature detector, or a covered electric wire to a fixed body via a supporting member, the supporting member However, it is a plate-like member long in the front-rear direction in which through holes are formed at two places in the longitudinal direction, and the plate thickness direction of this support member is up and down at two places on the flat plate portion between the two through holes. And the two through-holes located on both sides of the bent support member by folding a direction intersecting the longitudinal direction of the support member into a crease and bending both sides in the longitudinal direction of the support member downward at substantially the same set angle. The support member in a state in which the cable is inserted through the cable, and by bending each of the two through-hole positions and in a direction intersecting the cable insertion direction with a set angle upward, Serial is bent at the through-hole two positions, the support member may be fixed to the fixed body in this state.
Also, a cable fixing method for fixing a cable having a metallic or non-metallic covering member such as a sheathed thermocouple, a sheathed resistance temperature detector, or a covered electric wire to a fixed body via a supporting member, the supporting member Is a plate-like member that is long in the front-rear direction in which cutout portions cut out from one side in the width direction are formed in two longitudinal directions, and the two cutout portions are in a state where the plate thickness direction of the support member is up and down. Two portions of the flat plate portion in between and the direction intersecting with the longitudinal direction of the support member are creased, and both longitudinal sides of the support member are folded downward at substantially the same set angle, and both sides of the folded support member With the cable inserted into the two notches located at the side of the support member from one side in the width direction of the support member, the support member is folded at the position of the two notches and intersecting the cable insertion direction. Upward By folding setting angles, is bent to the cable by the notch two places, the support member may be fixed to the fixed body in this state.
In any of the above three methods, the cable is bent using the bending of the support member. This utilizes the property that the cable can be bent inherently, and the electrical properties at the bent portion of the cable do not change. In order for the cable to move in the longitudinal direction, the cable needs to be deformed once in a straight line, but the cable becomes straight when bent at one or two positions of the cable as described above. Is prevented and the cable cannot move in the longitudinal direction. In this case, the movement of the cable can be more effectively prevented by bending at two locations than at one location. Further, by forming the through hole for inserting the cable in the cutout portion, the timing for inserting the cable into the cutout portion may be freely changed.
[0007]
By crushing the support member from above, the support member is naturally bent at the position of the through-hole or notch where the shape retention strength is weak, and the cable can be bent. When the support member is crushed from above, the support member may be struck by a hammer or the like, or may be crushed by another method using power by a machine or the like.
[0008]
By forming one of the open ends of the notches formed in two places of the support member on one side in the width direction of the support member and forming the other open end on the other side in the width direction of the support member. Compared with the case where the open ends of the two notches are on the same side, the cable inserted through the notch can be made difficult to come off from the open end of the notch, and the bending work of the support member can be easily performed. it can.

1 and 2 show a state in which the sheath thermocouple 1 (cable) is fixed to a wafer (fixed body) 2 made of silicon, transparent or opaque quartz, or the like. In this embodiment, only the sheath thermocouple 1 will be described, but the present invention is also applicable to the case where a cable having a sheathed resistance temperature detector or other metallic or non-metallic covering member is fixed to the wafer (fixed body) 2. Can adapt. In addition to the wafer 2, the fixed body may be a structure made of wood, metal, synthetic resin, or the like, and various devices may be used as a fixed body to fix cables to various devices. May be.
[0010]
As shown in FIG. 7, the sheath thermocouple 1 is filled with magnesia (MgO) 4 as an insulating powder in a sheath 3 as a protective sheath, and a pair of strands 5 is placed in the magnesia (MgO) 4. , 6 are arranged.
[0011]
Next, a fixing method for fixing the sheath thermocouple 1 to the wafer 2 will be described.
First, the sheath thermocouple 1 is sent out so that the hot junction 7 bonded to the tip of the strands 5 and 6 is disposed in the recess 2A formed on the wafer 2. Thereafter, the hot contact 7 is fixed (embedded) in the recess 2A by filling the recess 2A with an adhesive material 8 such as ceramic cement.
Next, the sheath thermocouple 1 is moved between the support member 9 and the fixed (embedded) hot junction 7 by fixing an appropriate portion of the sheath thermocouple 1 to the wafer 2 via the support member 9. I don't want to do that.
More specifically, as shown in FIG. 1 and FIG. 2, a hook 12 is prepared in advance by welding a metal bar 11 to the lower surface of the metal disk 10. After inserting into the through-hole 2B formed in the wafer 2 from above (on the front surface side of the wafer 2), the same disk 13 as the disk 10 is applied to the bottom surface of the penetrating portion 11 from the back surface side of the wafer 2. The four corners of the metal support member 9 on which the plurality of sheathed thermocouples 1 are supported on the upper surface of the disk 10 positioned above are fixed by spot welding. S shown in FIG. 2 has shown the welding location. Although the case where the four sheathed thermocouples 1 are supported by the support member 9 is shown, any number of one, two, three, five or more may be used.
[0012]
A supporting method for supporting the plurality of sheathed thermocouples 1 (four in this embodiment) on the supporting member 9 will be described. First, a pair of through holes 9a as shown in FIG. , 9b is used to form the flat plate portion (intermediate portion) 9C between the two through holes 9a, 9b with the plate thickness direction being up and down as shown in the figure. Two of the end portions on the through-holes 9a, 9b side and the direction intersecting with the longitudinal direction of the support member 9 (orthogonal directions in this embodiment) are creases 9K, 9K, and the longitudinal direction of the support member 9 Fold both sides in the direction downward (see FIG. 3B). Note that both side portions 9A and 9B of the bent support member 9 are inclined at about 60 degrees downward with respect to the horizontal plane, but this angle may be between 5 degrees and 90 degrees. Any angle may be set.
Next, a plurality of sheathed thermocouples 1 are inserted into, for example, one through hole 9a and the other through hole 9b through the through holes 9a and 9b located on both side portions 9A and 9B of the bent support member 9 ( (See FIG. 3C). In this way, by bending each of the both sides in the longitudinal direction of the support member 9 downward at substantially the same angle, the straight sheathed thermocouples 1 are inserted from one through hole 9a to the other through hole 9b as shown in the figure. The vertical dimensions of the through-holes 9a and 9b that can be inserted through can be made substantially the same. Thereafter, the flat plate portion (intermediate portion) 9C of the support member 9 is crushed by the support member 9 as shown in FIG. The portions 9A and 9B are bent at the positions of the through holes 9a and 9b having the weakest shape retaining strength. 9H and 9H in the figure indicate folds. In the figure, it is possible to facilitate insertion of the sheathed thermocouples 1 to the through holes 9a and 9b by setting the vertical dimensions of the through holes 9a and 9b to be larger than the outer dimensions of the sheath thermocouples 1. However, the outer dimensions of the sheath thermocouples 1 and the vertical dimensions of the through holes 9a and 9b are set to be substantially the same so that the sheath thermocouples 1 can be inserted into the through holes 9a and 9b. Also good. By setting the vertical dimension of the through holes 9a and 9b in this way, the bending angle when the sheath thermocouples 1 are bent as described later is increased so that the sheath thermocouples 1 are formed in the through holes 9a and 9b. It can be made more difficult to move. Further, by making the distances from the through-holes 9a and 9b to the folds 9K and 9K the same, the two through-holes 9a and 9b positioned at both side portions 9A and 9B folded at the folds 9K and 9K are the same up and down. The sheath thermocouples 1 can be easily penetrated through the through holes 9a and 9b in a horizontal state as shown in the figure, but the two distances are different. Can also be implemented. The folds 9H and 9H are also provided at the same location as the folds 9K and 9K, but may be provided at different locations.
By crushing the support member 9 in this manner, the sheath thermocouples 1 are bent at two through holes, and in this state, the four corners of the support member 9 are fixed to the upper surface of the disk 10 by spot welding as described above. Thus, the sheath thermocouple 1 can be reliably prevented from moving in the longitudinal direction. By bending both side portions 9A and 9B of the support member 9 at the positions of the through holes 9a and 9b, that is, the folds 9H and 9H, the vertical dimension X of the through holes 9a and 9b shown in FIG. The vertical dimension Y is shortened as shown in FIG. This is because the vertical dimension of the through holes 9a and 9b is shortened by moving the lower side of the through holes 9a and 9b in the horizontal direction. In addition, although the location where the support member 9 is bent becomes a location on the lower end side where the shape retaining strength is the weakest by crushing the support member 9, the support member 9 is not crushed but the support member 9 is folded. Thus, the bent part can be set at any part of the through-holes 9a and 9b, but the vertical dimension of the through-holes 9a and 9b becomes shorter as it is located above the through-holes 9a and 9b. The clamping pressure for 1 will increase. By forming the support member 9 from a relatively soft metal such as aluminum having a thickness of 1 mm or less, there is an advantage that the support member 9 can be easily crushed and the support member 9 can be easily bent. In addition to other metal materials, the resin may be bent and deformed by heating to a softening temperature or higher.
[0013]
In the above embodiment, the through holes 9a and 9b are formed in the support member 9. However, as shown in FIG. 5 (a), the notch portion 14 into which the sheath thermocouples 1 can be inserted from one side in the width direction of the support member 9. , 15 may be formed. The cutouts 14 and 15 are wider than the insertion portions 14A and 15A formed so that the sheath thermocouples 1... Can be inserted into the open end portions, and are wider than the insertion portions 14A and 15A. 6, the sheath thermocouple 1... Holding portions 14 </ b> B and 15 </ b> B into which a stainless steel stopper 16 for fixing the support member 9 to the wafer 2 can be inserted. In the case of such notches 14 and 15, the sheath thermocouples 1 can be supported by the support member 9 simply by inserting the sheath thermocouples 1 from one side in the width direction of the support member 9. As described above, the work can be performed easily and quickly as compared with the case where the support member 9 is inserted into the through holes 9a and 9b.
Next, the case where the sheath thermocouples 1... Are supported on the support member 9 shown in FIG. First, after both sides of the support member 9 are folded at the creases 9K and 9K shown in FIG. 5 (a) as described above, as shown in FIG. 5 (b), the holding portions 14B of the flat support member 9 are provided. After the fasteners 16 are arranged so that the intermediate portions of the fasteners 16 having both ends 16A, 16A rounded and bent are positioned in 15B, as shown in FIG. The pair 1 is arranged in the holding portions 14B and 15B from the insertion portions 14A and 15A, and the support member 9 is placed in the longitudinal direction of the notch portions 14 and 15 at the arbitrary positions, that is, the folds 9H and 9H shown in the drawing as described above. The sheathed thermocouples 1 can be bent by bending in a direction crossing the direction. Thereafter, as shown in FIG. 6, both end portions 16A and 16A of the stoppers 16 and 16 are inserted into the recesses 17 and 17 formed on the wafer 2, and in this state, the adhesive 18 such as ceramic cement is inserted into the recesses. By filling 17, 17, the metal members 16, 16 are fixed to the wafer 2, and the support member 9 can be fixed to the wafer 2.
[0014]
The support member 9 may be configured as shown in FIG. That is, the open end of one of the insertion portions 14A and 15A of the cutout portions 14 and 15 is formed on one side in the width direction of the support member 9, and the open end of the other insertion portion 15A is supported. By forming the member 9 on the other side in the width direction, the sheath thermocouples 1 inserted from the support member 9 can be made difficult to come out as compared with the case where the member 9 is formed on the same side as described above.
[0015]
In the above embodiment, two portions of the support member 9 are bent. However, as shown in FIG. 9, the sheath thermocouple 1 is formed by bending only one portion of the hole 9a formed on the support member 9 as shown in FIG. ... may be bent at only one position and fixed to the wafer 2. The hole 9a may be formed in either the through hole or the notch. Since the structure for fixing the support member 9 to the wafer 2 is the same as described above, the description thereof is omitted.
[0016]
【The invention's effect】
By utilizing the inherent property of a cable that bends as in claim 1, the cable can be securely connected without the occurrence of a state in which the electrical characteristics are changed as in the prior art. It is possible to provide a cable fixing method that can be fixed to a fixed body and can be used favorably over a long period of time.
Moreover, since the cable can be bent by utilizing the bending of the support member, the cable can be bent at an arbitrary position when the cable is disposed.
Further, there is an advantage that the holding pressure of the cable can be changed depending on which position of the through hole or the notch is set as the position where the support member is bent.
Also, in the case of a notch, it is not necessary to consider the mounting order of the support members as in the case of the through holes, and the support member can be attached at the end. In addition to being able to improve the workability, the cable can be supported by being inserted from one side in the width direction of the support member.
[0017]
As described in claim 3 and claim 5, by bending the cable at two through holes or at two notches, the cable can be firmly fixed to the fixed body as compared with the case where the cable is bent only at one place. There are advantages.
[0018]
As described in claim 7, by forming the positions of the open ends of the two notches on both sides in the width direction of the support member, it is possible to make it difficult to pull out the cable from the notches, which is good for a long period of time. It is possible to enable support by a support member.
