【０００２】
【従来の技術】
図５は従来のこの種の防水クランプ１２の構造を示したものである。この防水クランプ１２は、テープ等によりワイヤーハーネスの如き被保持体を固定して保持する保持基体１３に支柱１４が立設され、該支柱１４の基部には該支柱１４を包囲するようにして皿状圧接体１５が一体に設けられ、支柱１４の先端には該支柱１４をパネル１６に形成された取付孔１７に差し込んだとき、パネル１６の後面１６ｂに係止して支柱１４の抜け出しを阻止する係止片１８が設けられ、更に支柱１４には皿状圧接体１５の前面に位置してウレタンで形成された環状の防水パッキン１９が係止片１８により抜け止めされて設けられ、前記支柱１４がパネル１６の取付孔１７に差し込まれ前記皿状圧接体１５により防水パッキン１９がパネル１６の前面１６ａに押し付けられた状態で前記支柱１４に設けられた係止片１８がパネル１６の後面１６ｂに係止する構造となっている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記の防水クランプ１２では防水パッキン１９がウレタンにより形成されているので、防水パッキン１９を形成するウレタンがパネル１６の後面１６ｂ側のウエットエリアから侵入する水を吸収し、このため完全防水が困難となる問題点があった。また、従来の構造では、支柱１４から防水パッキン１９が外れ易く、取り扱いに難があるといった問題点があった。
【０００４】
本発明の目的は、パネルに形成された取付孔からの防水を確実に行え且つ取り扱いが容易な防水クランプを提供することにある。
【０００５】
【課題を解決するための手段】
上記の目的を達成するため、請求項１に記載の発明は、被保持体を保持する保持基体と、該保持基体に立設されパネルに形成された取付孔に差し込まれる支柱と、該支柱の基部に該支柱を包囲するように設けられる皿状圧接体と、前記支柱の先端部に設けられ該支柱を前記取付孔に差し込んだ際に前記パネルの後面に係止して前記支柱の抜け出しを阻止する係止片とを備え、

前記皿状圧接体の前面の凹部内には、防水性と粘性とを有するゲル状物質を収容し、
前記保持基体の支柱を前記パネルに形成された取付孔に差し込むことにより、前記皿状圧接体は、この前面が前記パネルの前面に当接して押し広げられるように変形し、この前記皿状圧接体の変形により前記皿状圧接体の前面の前記凹部の容積が小さくなり、該凹部内に収容している前記ゲル状物質が変形して前記パネルの前面と前記皿状圧接体との間に液密に充満するとともに前記皿状圧接体の外周にはみ出した状態となり、この状態で前記係止片が前記パネルの後面に係止して、前記パネルの取付孔からの防水をできるようにしたことを特徴とする。
【０００６】
このように被保持体を保持する保持基体と、保持基体に立設されパネルに形成された取付孔に差し込まれる支柱と、支柱の基部に支柱を包囲するように設けられる皿状圧接体と、支柱の先端部に設けられこの支柱を取付孔に差し込んだ際にパネルの後面に係止して支柱の抜け出しを阻止する係止片とを備え、保持基体を、被保持体としてワイヤーハーネスをテープにより巻き付け固定して保持する平板形状に形成し、皿状圧接体を、係止片がパネルの後面に係止したとき皿状圧接体の前面がパネルの前面に圧接して弾性変形する素材で形成し、皿状圧接体の前面の凹部内に、防水性と粘性とを有するゲル状物質を収容しておくことにより、保持基体の支柱をパネルに形成された取付孔に差し込むことにより、皿状圧接体は、この前面がパネルの前面に当接して押し広げられるように変形し、この皿状圧接体の変形により皿状圧接体の前面の凹部の容積が小さくなり、この凹部内に収容しているゲル状物質が変形してパネルの前面と皿状圧接体との間に液密に充満するとともに皿状圧接体の外周にはみ出した状態となり、この状態で係止片がパネルの後面に係止して、パネルの取付孔からの防水を確実に行うことができる。
【０００７】
請求項２に記載の発明は、請求項１において、前記ゲル状物質としてブチルゴムを用いたことを特徴とする。
このように前記ゲル状物質としてブチルゴムを用いることにより、ブチルゴムの防水性と粘性によって、前記パネルの孔からの防水を確実に行うことができる。
【０００８】

このように前記ゲル状物質の表面に該ゲル状物質の硬化薄膜層を形成することにより、前記防水性と粘性とを有するゲル状物質の使用前の保護を図れ、前記ゲル状物質の表面に異物が付着したり、他の物体に付着したりするのを防止することができる。
【００１０】
【発明の実施の形態】
以下、本発明に係る防水クランプの実施の形態の一例を図面により詳細に説明する。
本例の防水クランプ１は、被保持体を保持する保持基体２に、パネル３に形成された取付孔４に差し込まれる支柱５を立設している。前記支柱５の基部には、該支柱５を包囲するように弾性変形する素材、例えばゴム或いは合成樹脂等で形成される皿状圧接体６を設け、該皿状圧接体６の前面の凹部６ａ内には防水性と粘性とを有するゲル状物質７を収容している。このゲル状物質７として本例ではブチルゴムを用いている。また、前記ゲル状物質７の表面には、ゲル状物質７の表面に異物が付着したり、ゲル状物質７が他の物体に付着したりするのを防止するためのものとして、セロハン紙からなる保護シート８を配置している。
【００１１】
更に、前記支柱５の先端部には、該支柱５を前記取付孔４に差し込んだ際にパネル３の後面３ｂに係止して支柱５の抜け出しを阻止する係止片９を設けており、前記係止片９がパネル３の後面３ｂに係止したとき前記皿状圧接体６の前面がパネル３の前面３ａに圧接して変形する状態となるようにしている。
【００１２】
上記のように構成された防水クリップ１の保持基体２に、被保持体となる例えばワイヤーハーネス１０をテープ１１により巻き付け固定して保持させ、支柱５を車両等のパネル３に形成された取付孔４に差し込む（図２）。このとき、前記皿状圧接体６の前面の凹部６ａ内のゲル状物質７の表面に配置されている保護シート８を除去しておく。
【００１３】
支柱５をパネル３の取付孔４に差し込み、支柱５に設けた係止片９が前記パネル３の取付孔４を通過すると、係止片９がパネル３の後面３ｂに係止して該取付孔４からの支柱５の抜け出しが阻止される。そして、前記支柱５の基部に設けられている皿状圧接体６は支柱５のパネル３の取付孔４への差し込みの過程でその前面がパネル３の前面３ａに当接して押し広げられるように変形し、この皿状圧接体６の変形により皿状圧接体６の前面の凹部６ａの容積が小さくなり、凹部６ａ内に収容している前記ゲル状物質７が変形して前記パネル３の前面３ａと前記皿状圧接体６との間に液密に充満し，この状態で前記係止片９がパネル３の後面３ｂに係止するので、前記パネル３の取付孔４からの防水を確実に行うことができる（図３）。このときの皿状圧接体６の変形は、ゲル状物質７が皿状圧接体６の外周にはみ出す位が好ましい。７ａは皿状圧接体６の外周にはみ出したゲル状物質である。
【００１４】
特に本例では、ゲル状物質７としてブチルゴムを用いており、ブチルゴムは防水性と粘性とに優れ、パネル３の取付孔４からの防水を確実に行うことができる。
【００１５】
また、本例のように、ゲル状物質７の表面に保護シート８を配置したので、防水性と粘性とを有するゲル状物質７の使用前の保護を図れ、該ゲル状物質７の表面に異物が付着したり、ゲル状物質７が他の物体に付着したりするのを防止することができる。
【００１６】
なお、上記本例では、ゲル状物質７の表面に保護シート８を配置して該ゲル状物質７の使用前の保護を図ったが、該ゲル状物質７の表面に該ゲル状物質７の硬化薄膜層７Ａを設けて、該ゲル状物質７の使用前の保護を図ることもできる（図４）。
【００１７】
【発明の効果】
以上のように本発明に係る防水クランプによれば、弾性変形する素材で形成されす皿状圧接体の前面の凹部内に防水部材として防水性と粘性とを有するゲル状物質を収容しているので、支柱をパネルの取付孔に差し込みパネルの前面で皿状圧接体を加圧変形させた際に、この皿状圧接体の変形による皿状圧接体の前面の凹部の容積が小さくなることにより、凹部内に収容してあるゲル状物質が変形して前記パネルの前面と前記皿状圧接体との間に液密に充満し，これによりパネルの取付孔からの防水を確実に行うことができる。
【００１８】
更に、構成が簡単なので取り扱いが容易であり、防水クランプのパネルへの取付作業も容易に行うことができる。
