Abstract
Description
MIケーブルの簡単な端部構造として、特許文献1及び特許文献2に示されているような、金属シースから露出させた素線とソフトケーブルの導線を接続した部分を金属スリーブで覆い、金属スリーブの中に絶縁材を充填したものがある。
マイクロヒータの場合、MIケーブル1の素線3、3は電気抵抗線で、MIケーブル1の端部は素線3、3の発熱により高温となることがあるため、耐熱性の面から樹脂は使用されることが少なく、金属スリーブ10の中には無機絶縁材粉末21が充填されて端部はガラス、セラミック等の耐熱性のあるシール部材14で封止されることが多い。また、無機絶縁材粉末21にはシール性はないので、金属スリーブ10のMIケーブル側端部15のMIケーブル1の金属シース2との全周溶接または全周ろう付けが必ず行われる。この全周溶接または全周ろう付と、シール部材14とにより、MIケーブル1内部は外気から遮断されており、金属スリーブ10と、無機絶縁材粉末21とによりMIケーブル1から露出した素線3、3は断線を防止されている。
上記課題を解決し上記目的を達成するために、本発明のうち第1の態様に係るものは、
円筒状の金属シースの中に1本または複数本の素線を、無機絶縁材粉末を介在させて収容したMIケーブルの端部構造において、
先端が軸方向に略直角に切断されたMIケーブルの端部に装着されたコネクタを有し、
コネクタは、
1つの貫通孔を有し、少なくとも一方の端部は金属シースの外面が内接する内径で厚みが金属シースより薄い円筒状部からなり、円筒状部にはMIケーブルの端部が挿入され、円筒状部の先端がMIケーブルの金属シースに全周溶接された金属スリーブと、
絶縁材からなり、金属スリーブ貫通孔内の挿入されたMIケーブルの先端より挿入方向前方の位置に設けられ、外周部が金属スリーブ全内周に当接して金属スリーブのMIケーブルが挿入された側に外気が入ることを遮断するハーメチックシールと、
MIケーブルの素線より硬い導体からなり、金属スリーブの貫通孔に、その貫通軸方向にハーメチックシールを貫通して挿入され、金属スリーブの円筒状部側の先端部が尖り、円筒状部側の逆側の後端部が棒状または円筒状をした、MIケーブルの素線と同じ本数の金属ピンと、を有し、
金属ピンは、先端部の軸方向が金属スリーブの円筒状部の軸方向と略一致し、その尖った先端が金属スリーブの円筒状部の軸方向と垂直な1つの面上に位置し、かつこの面上の先端の配置がMIケーブルの切断面における素線の配置と同じになるように配列されており、
MIケーブルの各素線の端面に1つの金属ピンの尖った先端が略垂直に突き刺さった状態で、かつ、金属ピンは互いに及び金属スリーブと接触しない状態で、金属ピンがハーメチックシールにより固定されていることを特徴とするものである。
さらに、各金属ピンはハーメチックシールにより互いに、及び金属スリーブと接触しない状態で保持されているので、金属ピン間及び金属ピンと金属スリーブとの間に接触が生じて絶縁抵抗が落ちることがない。
本発明のうち第2の態様に係るものは、第1の態様に係るMIケーブルの端部構造であって、
MIケーブルの末端の無機絶縁材粉末を除去し、その除去した部分に埋め込まれる樹脂からなるシール部材を設け、このシール部材によりMIケーブル内を外部からシールしたことを特徴とするものである。
本発明のうち第3の態様に係るものは、円筒状の金属シースの中に1本または複数本の素線を、無機絶縁材粉末を介在させて収容したMIケーブルの端部構造において、
先端が軸方向に略直角に切断されたMIケーブルの端部に装着されたコネクタを有し、
コネクタは、
1つの貫通孔を有し、少なくとも一方の端部は金属シースの外面が内接する内径で厚みが金属シースより薄い円筒状部からなり、円筒状部にはMIケーブルの端部が挿入され、円筒状部の先端がMIケーブルの金属シースに全周溶接された金属スリーブと、
絶縁材からなり、金属スリーブ貫通孔内の挿入されたMIケーブルの先端より挿入方向前方の位置に取り付けられ、貫通孔が設けられたストッパブロックと、
MIケーブルの素線より硬い導体からなり、金属スリーブの貫通孔に、その貫通軸方向にストッパブロックの貫通孔を介して挿入され、金属スリーブの円筒状部側の先端部が尖り、円筒状部側の逆側の後端部が棒状または円筒状をした、MIケーブルの素線と同じ本数の金属ピンと、
MIケーブル内を外部からシールするために設けられ、MIケーブルの末端の無機絶縁材粉末を除去し、その除去した部分に埋め込まれる樹脂からなるシール部材と、を有し、

MIケーブルの各素線の端面に1つの金属ピンの尖った先端が略垂直に突き刺さった状態で、かつ、金属ピンは互いに及び金属スリーブと接触しない状態で、金属ピンが、その凸部または曲がり部とストッパブロックの貫通孔との干渉部においてストッパブロックから押される力により固定されることを特徴とするものである。
また、金属ピンとストッパブロックの貫通孔との間のクリアランスは、金属ピンの角度変化が2度以下となるように取られているので、金属ピンの先端部のぶれは少なく、そのため、その先端部の軸方向が金属スリーブの円筒状部の軸方向と略一致し、その尖った先端は円筒状部の軸方向と垂直な1つの面上に位置し、かつその面上の配置がMIケーブルの切断面における素線の端面の配置と同じ配置になるように配列することが可能である。
その他、MIケーブルの素線はMIケーブルから露出しないため、外径の小さいMIケーブルであっても、その素線の断線を防護する必要がないこと、及び、従来のものと比べて作業ステップの減少と、煩雑な作業の回避から、製作時間の短縮を図ることができることは、第1及び第2の態様と同様である。また、装着されたコネクタのMIケーブルと逆側の端部は、金属スリーブ内若しくは金属スリーブ端面に、棒状(または、円筒状)をした金属ピンの後端部が立っているオスコネクタ(または、メスコネクタ)の形状をしていて、ソフトケーブルに取付けたメスコネクタ(または、オスコネクタ)に差し込むことでMIケーブルの素線とソフトケーブルの導線が接続されるもの同様である。
