Abstract

<P>PROBLEM TO BE SOLVED: To obtain a packaging method of an electronic component in a flat cable wherein the electronic component can be electrically connected at a packaging portion without using solder and conductive adhesive. <P>SOLUTION: A connection metal plate 4 is fixed on a portion corresponding to a flat conductor 1 of at least one surface of the flat cable 3. A portion wherein the flat conductor 1 and the connection metal plate 4 are overlapped is cut along two cut lines 6. A part 7a between the two cut lines 6 is made a step-difference in a laminating direction to both sides which intersect the cut lines 6, in such a manner that the connection metal plate 4 in the part exists inside the step-difference direction. Conduction joints 8 with which the connection metal plate 4 and the flat conductor 1 are mutually in contact are formed in ends in a longitudinal direction of the cut lines 6. A connecting conductor 11a of an electronic component is inserted in a gap 9 in the step-difference part between the part 7a between the two cut lines 6 and both of the sides intersecting the cut lines 6. <P>COPYRIGHT: (C)2004,JPO

【０００１】
【発明の属する技術分野】
本発明は、電気機器や自動車等の電気配線に使用されるフラットケーブルへの電子部品の実装方法及び実装接続部に関するものである。
【０００２】
【従来の技術】
従来のこの種の電子部品の実装方法及び実装接続部としては、特開平９−１５２０４６号の「フレキシブル配線基板への電子部品装着方法」に記載のように、基板（フレキシブルプリントサーキット基板等）にリフロー半田付け実装する方法や、特開平６−３１０８２６号の「フレキシブルプリント基板における電子部品の実装方法」に記載されているように導電性接着剤で実装する方法が一般的であった。配線体に直接実装する例はなく、前記基板を介してコネクタ等で配線体に接続させるのが普通である。
【０００３】
【発明が解決しようとする課題】
しかしながら、電子部品を実装箇所に半田や導電性接着剤で実装し、接続する方法では、スキルを必要とし、手間がかかり、コスト高になる問題点があった。
【０００４】
本発明の目的は、電子部品を実装箇所に半田や導電性接着剤を用いないで電気的に接続できるフラットケーブルへの電子部品の実装方法及び実装接続部を提供することにある。
【０００５】
【課題を解決するための手段】
本発明に係るフラットケーブルへの電子部品の実装方法は、フラット導体がフラット絶縁被覆で被覆されたフラットケーブルの少なくとも一方の面のフラット導体に対応する箇所に接続金属板が固定されていて、フラット導体と接続金属板との重なり箇所に２本の切れ目を設け、２本の切れ目の間の部分を、その部分の接続金属板が段違い方向の内側に存在するようにして、切れ目に交差する両側の部分に対して積層方向に段違いにし、切れ目の長手方向の端部に接続金属板とフラット導体とが相互に接触した導通接続部を形成し、２本の切れ目の間の部分と該切れ目に交差する両側の部分との段違い部分の隙間に電子部品の接続導体を差し込んで接続金属板に導通接続させることを特徴とする。
【０００６】
このようなフラットケーブルへの電子部品の実装方法では、フラットケーブルとこれにフラット導体に対応する箇所で固定された接続金属板との重なり箇所に２本の切れ目を入れ、これら２本の切れ目の間の部分を、その部分の接続金属板が段違い方向の内側に存在するようにして、切れ目に交差する両側の部分に対して積層方向に段違いにするので、切れ目の長手方向の端部に接続金属板とフラット導体とが相互に接触した導通接続部が形成され、接続金属板とフラット導体とが電気的に一体となる。この状態で、２本の切れ目の間の部分と該切れ目に交差する両側の部分との段違い部分の隙間に電子部品の接続導体を差し込んで接続金属板に導通接続させるので、電子部品の接続導体がフラットケーブルのフラット導体に電気的に接続されることになる。このため、電子部品を実装箇所に半田や導電性接着剤を用いないで電気的に接続することができる。このような実装方法によれば、スキルを必要とせず、手間がかからず、低コストで電子部品の接続を行うことができる。
【０００７】
また、本発明に係るフラットケーブルへの電子部品の実装方法は、フラット導体がフラット絶縁被覆で被覆されたフラットケーブルの少なくとも一方の面のフラット導体に対応する箇所に接続金属板がその長手方向の中央部に導体差し込み空間を設けて固定されていて、接続金属板の長手方向の少なくとも一方の端部におけるフラット導体との重なり箇所にコ字状の切れ目を設け、該コ字状の切れ目で囲まれていた舌片部をその周囲の重なり箇所に対して積層方向に段違いにし、該舌片部の段違い基部に接続金属板とフラット導体とが相互に接触した導通接続部を形成し、接続金属板の導体差し込み空間に電子部品の接続導体を差し込んで接続金属板に導通接続させることを特徴とする。

【発明の実施の形態】
図１乃至図４は本発明に係るフラットケーブルへの電子部品の実装構造の実施の形態の第１例を示したもので、図１は本例のフラットケーブルへの電子部品の実装構造の斜視図、図２は図１のＡ−Ａ線断面図、図３は図１のＢ−Ｂ線断面図、図４は図１のＣ−Ｃ線断面図である。
【００１８】
まず、本例のフラットケーブルへの電子部品の実装方法について説明する。本例では、平行に並設された複数のフラット導体１がフラット絶縁被覆２で一括して被覆されたフラットケーブル３の一方の面の１つのフラット導体１に対応する箇所に、接続金属板４が接着剤で接着されて固定されている。例えば、フラット導体１は厚さ０．２　ｍｍ、幅　５ｍｍで、フラット導体１の相互間隔を１０ｍｍとして並設し、これらフラット導体１を接着剤がついた厚さ０．１０ｍｍのポリエステルテープからなるフラット絶縁被覆２で一括して両側から覆ってフラットケーブル３を構成している。接続金属板４は、錫メッキされた銅製であって、厚さ０．１５ｍｍ、幅１５ｍｍ，長さ５０ｍｍである。
【００１９】
フラット導体１と接続金属板４との重なり箇所５に、図示しない雌刃型と雄刃型で上下からプレスして２本の平行な切れ目６を幅　５ｍｍ、長さ３５ｍｍで設ける。２本の平行な切れ目６の間の部分７ａを、その部分の接続金属板４が図２に示すように段違い方向の内側に存在するようにして、図１〜図４に示すように切れ目６に交差する両側の部分７ｂに対して積層方向に段違いにする。これにより、切れ目６の長手方向の端部に、図４に示すように接続金属板４とフラット導体１とが相互に接触した導通接続部８を形成する。このとき、切れ目６の長手方向の中央部では、切れ目６の間の部分７ａが切れ目６に交差する両側の部分７ｂに対して段違い方向に大きくずれていて、導通接続部８は形成されない。２本の平行な切れ目６の間の部分７ａと、該切れ目６に交差する両側の部分７ｂとの段違い部分の隙間９にホールＩＣの如き電子部品１０の一方の接続導体１１ａを差し込んで、図１乃至図３に示すように接続金属板４に導通接続させる。
【００２０】
電子部品１０の他方の接続導体１１ｂは、他の１つのフラット導体１の箇所で同様にして図１乃至図４に示すようにして接続する。
【００２１】
このようなフラットケーブルへの電子部品の実装方法では、フラットケーブル３とこのフラットケーブル３にフラット導体１に対応する箇所で固定された接続金属板４との重なり箇所５に２本の平行な切れ目６を設け、これら２本の平行な切れ目６の間の部分７ａを、その部分の接続金属板４が段違い方向の内側に存在するようにして、切れ目６に交差する両側の部分７ｂに対して積層方向に段違いにするので、切れ目６の長手方向の端部に接続金属板４とフラット導体１とが相互に接触した導通接続部８が形成され、接続金属板４とフラット導体１とが電気的に一体となる。この状態で、２本の平行な切れ目６の間の部分７ａと該切れ目６に交差する両側の部分７ｂとの段違い部分の隙間９に電子部品１０の接続導体１１ａ（１１ｂ）を差し込んで接続金属板４に導通接続させるので、電子部品１０の接続導体１１ａ（１１ｂ）がフラットケーブル３のフラット導体１に電気的に接続されることになる。このため、電子部品１０を実装箇所に半田や導電性接着剤を用いないで電気的に接続することができる。このような実装方法によれば、スキルを必要とせず、手間がかからず、低コストで電子部品の接続を行うことができる。
【００２２】
次に、本例のフラットケーブルへの電子部品の実装接続部について説明する。平行に並設された複数本のフラット導体１がフラット絶縁被覆２で一括して被覆されたフラットケーブル３の一方の面のフラット導体１に対応する箇所に接続金属板４が接着により固定されている。また、このフラット導体１と接続金属板４との重なり箇所５に２本の平行な切れ目６が設けられている。２本の平行な切れ目６の間の部分７ａは、その部分の接続金属板４が段違い方向の内側に存在するようにして、切れ目６に交差する両側の部分７ｂに対して積層方向に段違いに配置され、切れ目６の長手方向の端部に接続金属板４とフラット導体１とが相互に接触した導通接続部８が形成されている。そして、２本の平行な切れ目６の間の部分７ａと該切れ目６に交差する両側の部分７ｂとの段違い部分の隙間９に、電子部品１０の接続導体１１ａ，１１ｂが差し込まれて接続金属板４に導通接続されている。
【００２３】
このようなフラットケーブルへの電子部品の実装接続部では、フラットケーブル３とこれにフラット導体１に対応する箇所で固定された接続金属板４との重なり箇所５に２本の平行な切れ目６が設けられ、これら２本の平行な切れ目６の間の部分７ａが、その部分の接続金属板４が段違い方向の内側に存在するようにして、切れ目６に交差する両側の部分７ｂに対して積層方向に段違いにされているので、切れ目６の長手方向の端部に接続金属板４とフラット導体１とが相互に接触した導通接続部８が形成され、接続金属板４とフラット導体１とが電気的に一体となっている。この状態で、２本の平行な切れ目６の間の部分７ａと該切れ目６に交差する両側の部分７ｂとの段違い部分の隙間９に電子部品１０の接続導体１１ａ（１１ｂ）が差し込まれて接続金属板４に導通接続されているので、電子部品１０の接続導体１１ａ（１１ｂ）がフラットケーブル３のフラット導体１に電気的に接続された状態になる。このため、電子部品１０を実装箇所に半田や導電性接着剤を用いないで電気的に接続することができる。このような実装接続構造によれば、スキルを必要とせず、手間がかからず、低コストで電子部品１０の接続を行うことができる。
【００２４】
図５及び図６は図１に示すフラットケーブルへの電子部品の実装接続部に対する補強構造を示したもので、図５は本例の補強されたフラットケーブルへの電子部品の実装接続部の斜視図、図６は本例で用いるクランプ具の側面図である。
【００２５】
本例のフラットケーブルへの電子部品の実装接続部では、電子部品１０の接続導体１１ａ（１１ｂ）を接続している２本の平行な切れ目６の間の部分７ａの長手方向の両端の部分を、該切れ目６に交差する両側の部分７ｂと共にポリブチレンテレフタレート（ＰＢＴ）樹脂の如き電気絶縁樹脂で形成されたバネ形状を持つクランプ具１２でクランプしている。
【００２６】
このようにクランプ具１２を使用すると、電子部品１０の接続導体１１ａ（１１ｂ）を接続している部分の両側を機械的に押さえることができ、接続の信頼性を向上させることができる。
【００２７】
なお、これらの例で切れ目６は平行でなく、交差しない範囲で傾斜していてもよい。

【００３０】
電子部品１０の他方の接続導体１１ｂは、他の１つのフラット導体１の箇所で同様にして接続する。
【００３１】
このようなフラットケーブルへの電子部品の実装方法では、フラットケーブル３の一方の面のフラット導体１に対応する箇所に接続金属板４を、その長手方向の中央部に導体差し込み空間１３を設けて固定し、接続金属板４の長手方向の両端部におけるフラット導体１との重なり箇所５にコ字状の切れ目１４をそれぞれ設け、該コ字状の切れ目１４で囲まれていた各舌片部１５をその周囲の重なり箇所５に対して積層方向に段違いにするので、これら２つの舌片部１５の段違い基部１６に接続金属板４とフラット導体１とが相互に接触した導通接続部８が形成され、接続金属板４とフラット導体１とが電気的に一体となる。この状態で、接続金属板４の導体差し込み空間１３に電子部品１０の接続導体１１ａ（１１ｂ）を差し込んで接続金属板４に導通接続させるので、電子部品１０の接続導体１１ａ（１１ｂ）がフラットケーブル３のフラット導体１に電気的に接続されることになる。このため、電子部品１０を実装箇所に半田や導電性接着剤を用いないで電気的に接続することができる。このような実装方法によれば、スキルを必要とせず、手間がかからず、低コストで電子部品１０の接続を行うことができる。
