【発明の属する技術分野】
本発明は、溶接用ケ―ブル、特に絶縁性セパレ―タの放射状に４分割された分離片間に正側の撚り線導体と負側の撚り線導体とを交互に配設し、これら導体を正，負のタ―ミナルコンタクトエンドに圧着固定するようにした溶接用ケ―ブルに関するものである。
【０００２】
【従来の技術】
従来，絶縁性セパレ―タの放射状に４分割された分離片間に正側の撚り線導体と負側の撚り線導体とを交互に配設した溶接用ケ―ブルは普通に知られている。そして、このような溶接用ケ―ブルにおいて、ケ―ブルの端部からの各撚り線導体を正，負のタ―ミナルコンタクトエンドに圧着固定するものとして、例えば上下方向に位置する２本の正側の撚り線導体とこれらの撚り線導体と交差する左右方向に位置する２本の負側の撚り線導体とを各タ―ミナルコンタクトエンド内で、それぞれ上下方向或は左右方向に略同一レベルで整列させて取り付けるようにしたものが米国特許第４０１８９７６号明細書に開示されているように公知である。
【０００３】
【発明が解決しようとする課題】
ところが、上記公知の技術では、タ―ミナルコンタクトエンド内で上下方向に位置する撚り線導体とこれらの撚り線導体と交差する左右方向に位置する撚り線導体とをそれぞれ上下方向或は左右方向に略同一レベルに整列させるための構成が必要となり、そのため各タ―ミナルコンタクトエンドの構造が複雑となると共に前記整列させるための各タ―ミナルコンタクトエンドの長さが必要となって各タ―ミナルが長大化する虞がある。
【０００４】
本発明は、上記のような問題点に鑑みてなされたものであり、その目的とするところは、例えば上下方向に位置する２本の正側の撚り線導体とこれらの撚り線導体と交差する左右方向に位置する２本の負側の撚り線導体とをセパレ―タの端部近傍で孔を利用して位置の変更を行わせてからタ―ミナルコンタクトエンドに導くことにより各タ―ミナルコンタクトエンドの構造を簡略化すると共に各タ―ミナルの小型化が図れるような溶接用ケ―ブルを提供しようとするものである。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、本発明における溶接用ケ―ブルは、絶縁性セパレ―タの放射状に４分割された分離片間に正側の撚り線導体と負側の撚り線導体とを交互に配設した溶接用ケ―ブルにおいて、前記セパレ―タの端部近傍に、セパレ―タ内の分離片によって形成される各撚り線導体収容室の正側の撚り線導体収容室同士或は負側の撚り線導体収容室同士を連通させる孔を穿設し、一方の収容室内の撚り線導体を該孔を介して他方の収容室内へ移行させてセパレ―タ内の撚り線導体の位置を変更し、セパレ―タの端部における２本の正側の撚り線導体と２本の負側の撚り線導体とをそれぞれ上下方向或は左右方向で略同一面に整列してまとめ、該まとめられた各撚り線導体群をそれぞれのタ―ミナルコンタクトエンドに圧着固定するようにしたことを特徴とするものである。
【０００７】
また、絶縁性セパレ―タの放射状に４分割された分離片間に正側の撚り線導体と負側の撚り線導体とを交互に配設した溶接用ケ―ブルにおいて、前記セパレ―タの端部近傍に、セパレ―タ内の上下方向或は左右方向の分離片を除去して残留する分離片同士で平面形状を形成し、該平面に撚り線導体を通す貫通孔を穿設し、該孔を介して一方の面側に正側の撚り線導体が他方の面側に負側の撚り線導体が揃うように、撚り線導体を正・負の撚り線導体が交差する部位を絶縁部材でカバ―をして移行させてセパレ―タ内の撚り線導体の位置を変更し、セパレ―タの端部における２本の正側の撚り線導体と２本の負側の撚り線導体とをそれぞれ上下方向或は左右方向で略同一面に整列してまとめ、該まとめられた各撚り線導体群をそれぞれのタ―ミナルコンタクトエンドに圧着固定するようにしたことを特徴とするものである。
【０００８】
【発明の実施の形態】
図１ないし図５を参照してこの発明の一実施例について説明をする。
図において、１は溶接用ケ―ブルの概略を仮想線で示すものであり、該溶接用ケ―ブル１は絶縁性セパレ―タ２を具備しており、該絶縁性セパレ―タ２は放射状に４分割された例えば断面Ｔ字状の分離片３Ａ，３Ｂ，３Ｃ，３Ｄを有し、各分離片３Ａ，３Ｂ，３Ｃ，３Ｄ間には正側の撚り線導体４Ａ，４Ｂと負側の撚り線導体５Ａ，５Ｂとが交互に配設されている。
【０００９】
即ち、分離片３Ａ，３Ｂ間には正側の撚り線導体４Ａが、分離片３Ｂ，３Ｃ間には負側の撚り線導体５Ａが、分離片３Ｃ，３Ｄ間には正側の撚り線導体４Ｂが、分離片３Ｄ，３Ａ間には負側の撚り線導体５Ｂが、それぞれ配設されている。
【００１０】
そして、前記絶縁性セパレ―タ２の端部近傍には、セパレ―タ内の分離片３Ａと３Ｂとによって形成される正側の撚り線導体４Ａ収容室と、分離片３Ｃと３Ｄとによって形成される正側の撚り線導体４Ｂ収容室同士を連通する長孔６が穿設されている。なお、前記長孔６は負側の撚り線導体収容室同士を連通させる孔としてもよい。
【００１１】
上記のような構成によって、前記絶縁性セパレ―タ２の両端部近傍以外では、分離片３Ａ，３Ｂ間は正側の撚り線導体４Ａが、分離片３Ｂ，３Ｃ間は負側の撚り線導体５Ａが、分離片３Ｃ，３Ｄ間は正側の撚り線導体４Ｂが、分離片３Ｄ，３Ａ間は負側の撚り線導体５Ｂがそれぞれ通されているが、前記絶縁性セパレ―タ２の両端部近傍で、分離片３Ａ，３Ｂ間の正側の撚り線導体４Ａが前記長孔６を介して分離片３Ｃ，３Ｄ間の正側の撚り線導体４Ｂ側に移され、図４に示すように絶縁性セパレ―タ２の端部においては分離片３Ｃ，３Ｄ間で上下方向に正側の撚り線導体４Ａ，４Ｂが整列され、それらの側方で上下方向に負側の撚り線導体５Ｂ，５Ａが整列されることになる。
【００１２】
図６に示す絶縁性セパレ―タ２では、セパレ―タ２の端部近傍でセパレ―タ２内の上下方向の分離片３Ａ，３Ｃを除去して残留する分離片３Ｂ，３Ｄ同士で平面７形状を形成し、該平面７に撚り線導体を通す貫通孔８が穿設されている。
【００１３】
上記のような構成によって、前記絶縁性セパレ―タ２の両端部近傍以外では、分離片３Ａ，３Ｂ間は正側の撚り線導体４Ａが、分離片３Ｂ，３Ｃ間は負側の撚り線導体５Ａが、分離片３Ｃ，３Ｄ間は正側の撚り線導体４Ｂが、分離片３Ｄ，３Ａ間は負側の撚り線導体５Ｂがそれぞれ通されているが、前記絶縁性セパレ―タ２の両端部近傍で、分離片３Ａ，３Ｂ間の正側の撚り線導体４Ａが前記貫通孔８を介して平面７の裏面側に位置している正側の撚り線導体４Ｂ側に移され、また分離片３Ｂ，３Ｃ間の負側の撚り線導体５Ａが前記貫通孔８を介して平面７の表面側に位置している負側の撚り線導体５Ｂ側に移され、結果的には図６に示すように絶縁性セパレ―タ２の端部においては平面７の裏面側に正側の撚り線導体４Ａ，４Ｂが整列され、また平面７の表面側に負側の撚り線導体５Ｂ，５Ａが整列されることになる。
【００１４】
以上のようにしてセパレ―タの端部において、２本の正側の撚り線導体４Ａ，４Ｂと２本の負側の撚り線導体５Ａ，５Ｂとがそれぞれ上下方向或は左右方向で略同一面に整列してまとめられると、これらの撚り線導体は図７に示すようなタ―ミナル９に導かれ、正側の撚り線導体４Ａ，４Ｂが正のタ―ミナルコンタクトエンド１０に、負側の撚り線導体５Ａ，５Ｂが負のタ―ミナルコンタクトエンド１１に収納され、それぞれ圧着用カラ―１２，１３によって各タ―ミナルコンタクトエンド１０，１１に圧着され、正側の撚り線導体４Ａ，４Ｂが正のタ―ミナルコンタクトエンド１０に、負側の撚り線導体５Ａ，５Ｂが負のタ―ミナルコンタクトエンド１１にそれぞれ固定される。
【００１５】
なお、図７においてタ―ミナル９は、正側タ―ミナル１４と負側タ―ミナル１５とからなり、両タ―ミナル１４，１５はその間に絶縁板１６を介在させて適宜ボルト等によって一体化されるようになっている。また、図８は正側の撚り線導体４Ａ，４Ｂ及び負側の撚り線導体５Ａ，５Ｂがそれぞれ正のタ―ミナルコンタクトエンド１０及び負のタ―ミナルコンタクトエンド１１に圧着固定された状態の概略を示した断面図である。
【００１６】
以上のように、絶縁性セパレ―タ２の放射状に４分割された分離片３Ａ，３Ｂ，３Ｃ，３Ｄ間に正側の撚り線導体４Ａ，４Ｂと負側の撚り線導体５Ａ，５Ｂとを交互に配設した溶接用ケ―ブルであって、絶縁性セパレ―タ２の端部近傍で該セパレ―タ内の撚り線導体の位置を変更し、セパレ―タの端部における２本の正側の撚り線導体４Ａ，４Ｂと２本の負側の撚り線導体５Ａ，５Ｂとをそれぞれ上下方向或は左右方向で略同一面に整列してまとめ、該まとめられた各撚り線導体群をそれぞれのタ―ミナルコンタクトエンド１０，１１に圧着固定するようにしたので、従来技術のようなタ―ミナルコンタクトエンドにおいて各撚り線導体を整列させるための構成を必要とせず、そのため各タ―ミナルコンタクトエンド１０，１１の構造が簡略化されると共に各タ―ミナル１４，１５の小型化が図れるものである。そして、正側の撚り線導体４Ａ，４Ｂと負側の撚り線導体５Ａ，５Ｂとを絶縁性セパレ―タ２内で整列させるのも、所望の孔６又は８を絶縁性セパレ―タ２の端部近傍に形成することで解決されるので、撚り線導体の整列も容易にできるのである。
【００１７】
なお、絶縁性セパレ―タ２内で撚り線導体を整列させる際に少なくとも正・負の撚り線導体が交差するような部位では、各撚り線導体又は一方の撚り線導体を充分な絶縁部材でカバ―することで撚り線導体は安全なものとなる。
【００１８】

本発明に係る溶接用ケ―ブルは、絶縁性セパレ―タの放射状に４分割された分離片間に正側の撚り線導体と負側の撚り線導体とを交互に配設した溶接用ケ―ブルにおいて、前記セパレ―タの端部近傍で該セパレ―タ内の撚り線導体の位置を孔を利用して変更し、セパレ―タの端部における２本の正側の撚り線導体と２本の負側の撚り線導体とをそれぞれ上下方向或は左右方向で略同一面に整列してまとめ、該まとめられた各撚り線導体群をそれぞれのタ―ミナルコンタクトエンドに圧着固定するようにしたので、絶縁性セパレ―タ内での撚り線導体の整列が容易にでき、しかも、該溶接用ケ―ブルに適用される各タ―ミナルコンタクトエンドの構造を簡略化すると共に各タ―ミナルの小型化が図れるようなものである。
