Description

【０００１】
【発明の属する技術分野】
本発明は電線接続装置の改良に関する。
【０００２】
【従来の技術】
交差した複数の電線を簡単に電気的に接続する技術としては、例えば、実開昭５５−２１５５３号公報「電線接続装置」が知られており、同公報の第２図〜第４図に示される金属爪要素２０を、第１図の接続用孔９…（…は複数個を示す。以下同様。）に差込むものである。第１図によれば、４個一組の接続用孔９…に１個の金属爪要素２０を差込む構造になっており、差込んだ金属爪要素２０…は碁盤目配置となる。
碁盤目配置を図８、金属爪要素２０を図６及び図７で再度説明する。
【０００３】
図６は交差する電線を示す斜視図であり、例えば、電線１０１と電線１０２とを交差部１０３で導通させ、電線１０４と電線１０５とを交差部１０６で導通させるには、電線１０１，１０２，１０４，，１０５のそれぞれの絶縁被覆１０７，１０８，１１１，１１２を剥ぎ取り、中にある導体１１３と導体１１４、導体１１５と導体１１６を接触させる必要がある。
【０００４】
図７（ａ），（ｂ）は圧接形コネクタによる接続技術を説明する図であり、（ａ）は図６に示した交差部１０３の斜視図、（ｂ）は電線の接続状態を示す平面図である。
（ａ）において、絶縁被覆１０７，１０８を剥ぎ取るとともに、導体１１３，１１４同士を接触させるには、圧接形のコネクタ１１７を用いる。
【０００５】
コネクタ１１７は、４つのフォーク形状部１２１，１２２，１２３，１２４を備え、これらのフォーク形状部１２１，１２２，１２３，１２４にそれぞれテーパ部１２５（奥側は省略）と、エッジ部１２６（奥側は省略）と、刃部１２７とを備える。
【０００６】
コネクタ１１７で電線１０１，１０２を接続するには、電線１０１，１０２にコネクタ１１７を押し付けることで、コネクタ１１７のテーパ部１２５で電線１０１，１０２をコネクタ１１７内に導き、エッジ部１２６で絶縁被覆１０７，１０８を剥ぎ取り、刃部１２７で導体１１３，１１４を挟み込む。
【０００７】
（ｂ）において、導体１１３とコネクタ１１７とが圧接部１３１，１３２で導通し、導体１１４と圧接形コネクタ１１７とが圧接部１３３，１３４で導通するため、導体１１３と導体１１４とはコネクタ１１７を介して導通する。
【０００８】
図８は圧接形コネクタの従来の配置を示す平面図であり、電線１３５，１０１，１０４，１３７を等しいピッチｐで並べ、これらの電線１３５，１０１，１０４，１３７に直交させて電線１３８，１０２，１０５を同じく等しいピッチｐで並べ、コネクタ１１７…により、電線１０１と電線１０２とを交差部１０３で導通させ、電線１０４と電線１０５とを交差部１０６で導通させ、電線１３５と電線１０５とを交差部１４１で導通させ、電線１３７と電線１３８とを交差部１４２で導通させたことを示す。
【０００９】
そして、想像線で示したコネクタ１１７Ｂ…を含め、交差部の全てを対象にコネクタ１１７を配置することが可能であり、本例では碁盤目状に並んだ交差部の内の交差部１０３，１０６，１４１，１４２に配置する。
従って、例えば、４個のコネクタ１１７を配置するために必要なスペースは、コネクタ１１７の幅ｗとコネクタ１１７，１１７間の距離ｃとによって決まり、横の長さがａ、縦の長さがｂである。このスペースは電線１３５，１０１，１０４，１３７，１３８，１０２，１０５及び４つのコネクタ１１７を収納する電線接続装置の大きさに相当する。
上記スペースは、図４で説明するスペースｓｐ１と比較するためのものである。
【００１０】
【発明が解決しようとする課題】
しかしながら、近年、自動二輪車等で使用者のニーズにより車載電気部品が増加する傾向にあり、電線を接続するための電線接続装置が大型になり、大きなスペースを占有するため、この電線接続装置の小型化が望まれている。
そこで、本発明の目的は、小型の電線接続装置を提供することにある。
【００１１】
【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の請求項１は、平行に並べた複数の横向き電線に、平行に並べた複数の縦向き電線を交差させ、これらの横向き電線と縦向き電線との交差部の各々に、圧接形コネクタに横向き電線及び縦向き電線のそれぞれに導通させるために同一方向に向けて一体に形成された横向き圧接部・縦向き圧接部の各２枚の刃部を圧接コネクタ毎に押付け、この２枚の刃部で横向き電線及び縦向き電線の絶縁被覆をカットするとともに２枚の刃部を横向き電線及び縦向き電線の導体に接触させる形式の電線接続装置において、平面視で少なくとも１本の横向き電線上に複数の圧接形コネクタを所定の間隔で配置し、他の横向き電線上の他の圧接形コネクタを、所定の間隔の中間位置に、且つ複数の圧接形コネクタの横幅に一部をオーバーラップさせて配置することで、複数個の圧接形コネクタを千鳥配置可能にするとともに、平面視で少なくとも１本の縦向き電線上に複数の圧接形コネクタを所定の間隔で配置し、他の縦向き電線上の他の圧接形コネクタを、所定の間隔の中間位置に、且つ複数の圧接形コネクタの縦幅に一部をオーバーラップさせて配置することで、複数個の圧接形コネクタを千鳥配置可能にした。
複数個の圧接形コネクタを千鳥配置したので、従来の碁盤目配置に比較して圧接形コネクタの占めるスペースが小さくなり、電線接続装置をコンパクトにすることができる。
【００１２】
【発明の実施の形態】
本発明の実施の形態を添付図に基づいて以下に説明する。なお、図面は符号の向きに見るものとする。
図１は本発明に係る電線接続装置の平面図であり、電線接続装置１は、ベース部２と、このベース部２に縦に並べた複数の電線で構成する縦向き電線群３と、この電線群３に直角に重ねて並べた複数の電線で構成する横向き電線群４と、これら縦向き電線群３及び横向き電線群４の電線の各交差部を結線するための圧接形コネクタ５…と、これらベース部２、縦向き電線群３、横向き電線群４及び圧接形コネクタ５…を覆うカバー部６とからなる。
【００１３】

また、第２電線支持部は、横向き電線４ａ，４ｂ，４ｃ，４ｄ，４ｅ，４ｆのそれぞれを挿入して位置決めするための複数の半円断面溝（図示せず）を備える。
【００１６】
図３は本発明に係る圧接形コネクタ及び電線の斜視図であり、圧接形コネクタ５は、板材で一体的に形成したのもであり、例えば、縦向き電線３ｄに導通させるためにフォーク状に形成した第１・第２圧接部２１，２２と、例えば、横向き電線４ａに導通させるためにフォーク状に形成した第３・第４圧接部２３，２４と、これら第１圧接部２１、第２圧接部２２、第３圧接部２３及び第４圧接部２４を繋ぐ基部２５とからなる。なお、縦向き電線３ｄは、複数の素線（図示せず）を撚り合せた導体３ｍと、この導体３ｍを包む絶縁被覆３ｎとからなり、また、横向き電線４ａは、複数の素線（図示せず）を撚り合せた導体４ｍと、この導体４ｍを包む絶縁被覆４ｎとからなる。
【００１７】
第１・第２圧接部２１，２２と第３・第４圧接部２３，２４とは、直交して重なる縦向き電線３ｄと横向き電線４ａとの結線を行うために、高さが異なるものである。
第１圧接部２１、第２圧接部２２はそれぞれに、縦向き電線３ｄを押し込むためのスロット部２６，２７を備える。
第３圧接部２３及び第４圧接部２４はそれぞれに、横向き電線４ａを押し込むためのスロット部２８，２９を備える。
【００１８】
第１圧接部２１と第２圧接部２２とは、平行であり、これらの第１・第２圧接部２１，２２のそれぞれの外面３１，３２間の距離、即ち、幅をｗとする。
また、第３圧接部２３と第４圧接部２４とは、同じく平行であり、これらの第３・第４圧接部２３，２４のそれぞれの外面３３，３４間の距離、即ち、幅をｗ（図示せず）とする。
【００１９】
スロット部２６は、それぞれ開口側から順に、縦向き電線３ｄをガイドするための第１傾斜部３５，３５（片側は省略）と、絶縁被覆３ｎを剥がすためのエッジ部３６，３６（片側は省略）と、導体３ｍの素線を圧縮及び再配列させる第２傾斜部３７，３７（片側は省略）と、エッジ部３６，３６の被覆剥離の効果を高めるために第１傾斜部３５，３５及び第２傾斜部３７，３７の外側面に形成した面取り部３８，３８と、導体３ｍに押し付けて圧接保持するための刃部４１，４１（片側は省略）と、スロット部２６に縦向き電線３ｄを押し込んだときに応力の集中を防ぐアール部４２とからなる。
スロット部２７，２８，２９は、スロット部２６と同一形状であり、説明を省略する。
【００２０】
図２に示したコネクタ挿入溝１２は、各交差部に圧接形コネクタ５…を押付けるときに、溝底で図３に示した圧接形コネクタ５の第１・第２圧接部２１，２２のストッパの役目をし、スロット部２６，２７，２８，２９の各刃部４１，４１のほぼ中央に導体３ｍ，４ｍを位置させるためのものである。
【００２１】
図４は図１の圧接形コネクタ部を拡大した平面図であり、圧接形コネクタ５の幅ｗ及び隣の圧接形コネクタ５との距離ｃを従来と同一に保ったうえで、縦向き電線３ｄと横向き電線４ａとの交差部５１、縦向き電線３ｆと横向き電線４ａとの交差部５２、縦向き電線３ｅと横向き電線４ｃとの交差部５３、縦向き電線３ｇと横向き電線４ｄとの交差部５４にそれぞれ圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄ（圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄは圧接形コネクタ５と同一のものであるが、説明の都合上、区別した。）を押付けて、圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄを千鳥配置したことを示す。（千鳥配置については、図５で詳細に述べる。）
【００２２】
即ち、圧接形コネクタ５ｃの横方向位置を、圧接形コネクタ５ａと圧接形コネクタ５ｂとの中央に配置した。換言すると、圧接形コネクタ５ａ，５ｂ間の横方向ピッチ（電線３ｄ，３ｆ間のピッチに等しい）ｐに対して、圧接形コネクタ５ａ，５ｃ間の横方向ピッチを０．５ｐにした。
また、圧接形コネクタ５ｃ，５ｄ間の横方向ピッチをｐにするとともに、圧接形コネクタ５ｃ，５ｄの縦方向ピッチを０．５ｐにした。
【００２３】
ここで、例えば、４個の圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄを配置するために必要なスペースは一点鎖線で示したｓｐ１であり、横の長さがＡ、縦の長さがＢである。
従って、このスペースｓｐ１は、従来のコネクタを４個配置するためのスペースｓｐ２（横の長さがａ、縦の長さがｂ）に比較して格段に小さい。
【００２４】
このように、圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄの大きさ及び圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄ同士の距離ｃを従来と同一に保ったうえで、複数の圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄを千鳥配置したことにより、圧接形コネクタ５ａ，５ｂ，５ｃ，５ｄが占めるスペースを小さくすることができ、これによって、電線接続装置１（図１参照）を小型化できる。
【００２５】
以上に述べた圧接形コネクタ５の配置について次に詳細に説明する。
図５（ａ）〜（ｃ）は本発明に係る圧接形コネクタの配置を説明する模式図である。なお、ここでは横向き・縦向き電線に符号ｄ，ｅ及び符号ｆ，ｇを付ける。

【００２８】
本発明における千鳥配置とは、▲１▼（ａ）の碁盤目配置と（ｂ）の縦ずらし配置とを組合わせたもの、▲２▼（ａ）の碁盤目配置と（ｃ）の横ずらし配置とを組合わせたもの、▲３▼（ａ）の碁盤目配置と（ｂ）の縦ずらし配置と（ｃ）の横ずらし配置とを組合わせたものをいう。なお、（ａ）〜（ｃ）における圧接形コネクタ５は、それぞれ少なくとも１個配置すればよい。また、上記▲１▼〜▲３▼では、（ａ）〜（ｃ）におけるそれぞれの圧接形コネクタ５の少なくとも１個は、異なる横向き電線ｄ，ｆ又は縦向き電線ｅ，ｇに配置するものである。
