Description

【０００１】
【発明の属する技術分野】
本発明は、自動車のパネル貫通孔に装着させるグロメットに挿通させるワイヤハーネスの電線間の防水を図るためのワイヤハーネスの止水処理方法及び止水処理に用いる電線保持具に関するものである。
【０００２】
【従来の技術】
従来より、例えば自動車の車室の内外を仕切るパネル等を通して配索されるワイヤハーネスでは、パネルに設けられている貫通孔にゴム製のグロメットが装着される。このグロメットを通してワイヤハーネスが配索されることで、グロメットとパネル貫通孔との間を確実にシールして、パネルの貫通孔から車室内へ浸水するのを防止している。
【０００３】
しかし、グロメットとワイヤハーネスの電線との間や各電線間に隙間があると、この隙間を通して車室内に浸水する可能性があるので、これらの隙間もシールする必要がある。
【０００４】
そこで、前記隙間をシールするために、特開平１０−２２４９６０号公報に示されているような装置を用いて電線間のシールが行なわれている。
すなわち、図３に示したように、ワイヤハーネス組立用の配索板１１の上には、複数本の電線からなる電線群を所定の配索形態に応じた分岐形状に支持するために複数の電線群受け治具１２a、１２b、１２c、１２d、１２e が取り付けられており、その途中の所定位置には電線群Ｗに止水剤を塗布して防水処理を行うための防水処理用治具１３が配置されている。
【０００５】
防水処理用治具１３では、配索板１１の上に治具板１４を取り付け、この治具板１４の上に所定間隔をおいて一対の電線保持具１５、１５が立設されている。この電線保持具１５には、グロメット挿通部位の電線１６（図4（A）参照）を１本ずつ縦方向に整列させて保持するためのスリット１７が各々設けられている。
【０００６】
このような装置を用いて、以下の手順で防水処理を行う。すなわち、先ず図４（Ａ）に示したように、電線保持具１５のスリット１７によりグロメット挿通部位の電線１６を縦方向に１列に整列させる。
次に、図４（Ｂ）に示したように、一対の電線保持具１５、１５間に整列した電線１６の表面に、止水剤塗布ノズル１８により未固化状態の止水剤１９を塗布する。
【０００７】
次に、図４（Ｃ）に示したように、止水剤１９を塗布した電線１６の一方の表面に束ねるための帯状フィルム２１を貼付して、電線１６を１列の整列状態に連結した後、電線１６を防水処理用治具１３から取り外す。
次に、図４（Ｄ）に示したように、帯状フィルム２１を巻き締めて、電線１６を円形断面に結束する。
【０００８】
次に、図４（Ｅ）に示したように、帯状フィルム２１の結束位置の上にテープ２２を巻き付けて、電線１６の断面寸法をグロメットのハーネス挿通孔に緊密嵌合する円形状にすると共に、止水剤１９を固化させる。
そして、最後に図４（Ｆ）に示したように、テープ２２の巻き付け位置の上にグロメット２３を装着する。
【０００９】
【発明が解決しようとする課題】
しかしながら、上記従来の止水処理方法においては、電線１６を１列の整列状態に保持した状態で止水剤１９を塗布するため、電線１６の本数が多くなると、電線１６を１列に整列させるための細幅の電線保持具１５が上下方向に長くなり、布線するのが困難になるという問題があった。
【００１０】
本発明の目的は、上記従来の問題点に着目してなされたものであり、止水処理を行う際に容易に電線を布線することのできるワイヤハーネスの止水処理方法及び電線保持具を提供することにある。
【００１１】
【課題を解決するための手段】
上記課題を解決するために、本発明の請求項１記載のワイヤハーネスの止水処理方法は、パネル貫通孔への装着用グロメットに挿通させるワイヤハーネスの電線に止水処理を行うワイヤハーネスの止水処理方法であって、
前記ワイヤハーネスの布線を行う治具板上で当該ワイヤハーネスを配索し、止水処理を行う部分に近接した位置に立設されている櫛状の電線保持具に前記電線を引っ掛けて上下方向に平面状に広げ、平面状に広げた前記電線の片側または両側から止水剤を塗布することを特徴とする。
【００１２】
前記構成のワイヤハーネスの止水処理方法によれば、治具板上にワイヤハーネスを配索し、止水処理を行う部分に近接した位置に立設されている櫛状の電線保持具に電線を一定のまとまりごとに引っ掛けるので、電線本数が増加しても電線を上下方向に極端に長くすることなく平面状に広げることができる。
そして、広げた電線の片側または両側から止水剤を塗布するので、確実に電線間に止水剤を塗布することができる。
【００１３】
また、本発明の請求項２記載のワイヤハーネスの止水処理方法によれば、請求項１記載のワイヤハーネスの止水処理方法であって、前記電線保持具に所定間隔で上下方向に複数設けられている櫛歯状の各電線支持アームに前記電線を均等に引っ掛けることを特徴とする。
【００１４】
前記構成のワイヤハーネスの止水処理方法によれば、櫛歯状に設けられている複数の電線支持アームに均等に電線を引っ掛けるので、電線本数が増加しても電線を上下方向に平面状に広げることができる。
【００１５】
更に、本発明の請求項３記載の電線保持具によれば、パネル貫通孔への装着用グロメットに挿通させるワイヤハーネスの電線に対する止水処理に用いる電線保持具であって、
前記ワイヤハーネスの布線を行う治具板上に立設される支柱と、該支柱から同一鉛直面内の上下方向に所定間隔で水平方向に設けられた複数の櫛歯状の電線支持アームと、を備えていることを特徴とする。
【００１６】
前記構成の電線保持具によれば、上下方向に複数設けられている櫛歯状の電線支持アームに電線を一定のまとまりごとに引っ掛けるので、電線本数が増加しても電線を上下方向に平面状に広げることができ、容易に止水剤を塗布することができる。
【００１７】
【発明の実施の形態】
以下、本発明のワイヤハーネスの止水処理方法及び止水処理に用いる電線保持具の一実施形態を図１及び図２に基づいて詳細に説明する。図１は本発明に係るワイヤハーネスの止水処理方法を示す斜視図、図２は本発明に係る電線保持具を示す正面図である。なお、従来技術と共通する部位には同じ符号を付して、重複する説明を省略する。
【００１８】
図２に示すように、本実施形態の電線保持具３１は、櫛状であり、上下方向に伸びる支柱３１ａと、この支柱３１ａから同一鉛直面内で上下方向に所定間隔に設けられ、且つ水平方向に突設された複数の櫛歯状の電線支持アーム３１ｂとから構成されている。
支柱３１ａは、ワイヤハーネスW／Hの電線１６に止水剤１９を塗布する止水処理部３２に近接した治具板１４上に立設され、電線支持アーム３１ｂは電線１６の布線方向に直交する方向に配置されている（図３参照）。なお、電線支持アーム３１ｂの長さＢは、配索する電線のサイズや本数を考慮して十分に電線１６を保持できる長さに設定されている。また、各電線支持アーム３１ｂの数や間隔Ｄ等は、布線される電線１６の本数に応じて適宜設定されている。
【００１９】
次に、本実施形態に係るワイヤハーネスの止水処理方法について説明する。
図１に示すように、電線保持具３１を止水処理部３２の近傍に立設し、複数の電線支持アーム３１ｂが布線方向に直交するようにセットしておく。
そして、ワイヤハーネスW／Hの電線１６を布線する治具板１４（図３参照）上で電線１６を配索し、この電線１６を電線保持具３１の複数の電線支持アーム３１ｂに一定の本数を一まとまりとして引っ掛けて、電線１６を上下方向に平面状に広げる。この平面状に広げた電線１６の片側または両側から止水剤１９を塗布する。
【００２０】
その後、電線１６を電線保持具３１から取り外して、図４で説明したように、帯状フィルム２１を巻き締め、電線１６を円形断面に結束して上にテープ２２を巻きつけて、電線１６の断面寸法をグロメットのハーネス挿通孔に緊密嵌合する円形状にする。そして、止水剤１９を固化させてから、最後にグロメット２３を装着する。
【００２１】
以上の結果から、電線１６の本数が増加しても布線時に障害となることなく、容易に電線１６を上下方向へ略平面状に広げて整列することができるので、電線１６間に止水剤１９を塗布して浸透させることができ、確実に止水処理を行うことができる。
また、電線１６の本数に合わせて、電線支持アーム３１ｂの間隔Ｄや長さＢが適当なものを適宜選択することにより、容易に電線１６を電線支持アーム３１ｂに引っ掛けることができる。
【００２２】
【発明の効果】
以上説明したように本発明のワイヤハーネスの止水処理方法及電線保持具によれば、止水処理を行う部分に近接した位置に立設されている櫛状の電線保持具に電線を一定のまとまりごとに引っ掛けるので、電線本数が増加しても電線を上下方向に平面状に広げることができる。
従って、止水処理を行う際に容易に電線を布線することのでき、広げた電線の片側または両側から止水剤を塗布することができるので、電線間に止水剤を確実に浸透させることができる。
