【発明が解決しようとする課題】
しかしながら、上記端子取付構造であると、端子４及び端子４を接続している電線ｗが電気接続箱１の外部で露出しているので、電線ｗに引っ張りや曲げが生じると、圧着部４ａと端子本体４ｂとの間の屈曲部に応力が集中し、該屈曲部に破断が生じて、端子４と電気接続箱内のバスバーとの電気接続に不具合が生じる恐れがある。
【０００５】
本発明は上記問題に鑑みてなされたものであり、電気接続箱内のバスバーと接続する端子及び該端子を取り付けている電線にプロテクタを外装することにより、端子の破損を防止し、電気接続の信頼性を高めることを課題としている。
【０００６】
【課題を解決するための手段】
上記課題を解決するため、本発明は、直角に屈曲すると共に該屈曲部側にボルト穴を設けた端子を接続した電線をプロテクタに通し、該プロテクタを電気接続箱の外面に取り付けると該電気接続箱内のバスバー上に上記電線端末の端子が突出し、該端子とバスバーとを電気接続箱内に固定しているナットにボルト締めで接続固定するために用いるプロテクタであって、
本体部と、該本体部の一側縁に薄肉ヒンジを介して一体的に設けた蓋部を備え、上記本体部に上記電線の端末に取り付けた上記端子の圧着部を収容する凹部からなる圧着部収容空間を設けていると共に、該圧着部収容空間の先端に連続し、上記端子の圧着部と屈曲部の間に延在する中間部と同形状とした端子位置決め保持部を設けており、
上記端子位置決め保持部に上記電線端末の端子の中間部を収容した状態で上記蓋を本体部に被せて結合すると、該本体部の他側縁と上記蓋部の隙間から上記端子の屈曲部が突出し、該プロテクタを上記電気接続箱に付設すると上記端子の屈曲部が電気接続箱内のバスバー上面に載置される構成としている電気接続箱に付設するプロテクタを提供している。
【０００７】
上記構成とすると、電気接続箱内のバスバーと接続する端子及び該端子を取り付けている電線を上記プロテクタ内に収容し、該プロテクタを電気接続箱に付設しているので、端子の破損を防止することができ、端子とバスバーとの電気接続の信頼性を高めることができる。
【０００８】
上記蓋部の内面にロック爪を突設している一方、上記本体部にロック爪が挿入係止するロック穴を設け、かつ、上記蓋部あるいは本体部に電気接続箱との係止部を設けている。
【０００９】
上記構成とすると、蓋部に設けたロック爪を本体部に設けたロック穴に挿入係止して、本体部と蓋部とをロック結合することにより、端子位置決め保持部内に嵌め込んだ端子を蓋部により押さえ込んで、端子を端子位置決め保持部内に確実に収容して位置決めすることができる。また、蓋部あるいは本体部に設けた電気接続箱との係止部により、プロテクタを電気接続箱に位置決めすることができるので、バスバーと端子の位置決めがしやすく、ボルト締め作業を容易にすることができる。
【００１０】
上記プロテクタに挿通する電線にコルゲートチューブを外装しており、上記本体部の圧着部収容空間の電線挿入側先端に連続させて設けた凹部からなるコルゲートチューブ係止部の内面および該コルゲートチューブ係止部に対向する蓋部の内面に、コルゲートチューブの凹部に係止するリブを設けている。
【００１１】

【００２５】
また、蓋部１２に設けたロック爪１２ｄを本体部１１に設けたロック穴１１ｅに挿入係止して、本体部１１と蓋部１２とをロック結合することにより、端子位置決め保持部１４ａ、１５ａ内に嵌め込んだ端子２０、２１を蓋部１２により押さえ込んで、端子２０、２１を端子位置決め保持部１４ａ、１５ａ内に確実に収容して位置決めすることができる。また、本体部１１に設けた電気接続箱４０との係止部１１ｃにより、プロテクタ１０を電気接続箱４０に位置決めすることができるので、バスバー４２、４３と端子２０、２１の位置決めがしやすく、ボルト締め作業を容易にすることができる。
【００２６】
さらに、リブ１４ｂ−１、１５ｂ−１を電線ｗ１、ｗ２に外装したコルゲートチューブ３０の凹部３０ａに係止しているので、コルゲートチューブ３０の位置決めを容易にすることができる。また、コルゲートチューブ３０をプロテクタ１０内に位置決め固定しているので、電線ｗ１、ｗ２に引っ張りや曲げが生じても端子２０、２１には応力がかからず、端子２０、２１の破損を防止することができる。
【００２７】
【発明の効果】
以上の説明より明らかなように、本発明によれば、電気接続箱内のバスバーと接続する端子及び該端子を取り付けている電線を上記プロテクタ内に収容し、該プロテクタを電気接続箱に付設しているので、端子の破損を防止することができ、端子とバスバーとの電気接続の信頼性を高めることができる。
【００２８】
また、蓋部に設けたロック爪を本体部に設けたロック穴に挿入係止して、本体部と蓋部とをロック結合すると、端子位置決め保持部内に嵌め込んだ端子を蓋部により押さえ込んで、端子を端子位置決め保持部内に確実に収容して位置決めすることができる。また、蓋部あるいは本体部に電気接続箱との係止部を設けると、プロテクタを電気接続箱に位置決めすることができるので、バスバーと端子の位置決めがしやすく、ボルト締め作業を容易にすることができる。
【００２９】
さらに、コルゲートチューブ係止用のリブを設けて、電線に外装したコルゲートチューブの凹部に係止すると、コルゲートチューブの位置決めを容易にすることができる。この場合、コルゲートチューブをプロテクタ内に位置決め固定しているので、電線に引っ張りや曲げが生じても端子には応力がかからず、端子の破損を防止することができる。
