【発明の属する技術分野】
本発明は、扁平状のワイヤハーネス、フレキシブルフラットケーブル（ＦＦＣ）、フレキシブルプリント回路体（ＦＰＣ）等のフラットケーブルを車体等の固定体に固定するためのフラットケーブル用取付部材に関するものである。
【０００２】
【従来の技術】
自動車には、各種制御等のために多数の電子機器や機械部品が搭載されている。これら電子機器等は、扁平状のワイヤハーネス、フレキシブルフラットケーブル（ＦＦＣ）、フレキシブルプリント回路体（ＦＰＣ）等の可撓性を有するフラットケーブルによって電気的に接続される。このように車両には多数の例えばＦＦＣが配索されており、これらＦＦＣは、周囲の部品と干渉したり、可動部品に噛み込まれたりしないように、例えばフラットケーブル用取付部材を用いて所定箇所ごとに車体に固定される。
【０００３】
フラットケーブル用取付部材としては種々のものが提案されている（例えば、特許文献１、２参照。）。
例えば、特許文献１に開示されている第１のフラットケーブル用取付部材としてのフラットケーブル用クランプは、図６に示すように、係止部材１０１を係止孔１０２から抜き出し、係止部材１０１の下側から張出部材１０３の下側に向けてフラットケーブル１０４を挿入し、フラットケーブル１０４の一方の側端を挟持部１０５内に差し込む。次いで、フラットケーブル１０４の他方の側端を挟持部１０６上に位置決めした後、係止部材１０１を係止孔１０２内に挿通する。これにより、バネ片１０７によってフラットケーブル１０４が幅用弾性部１０８及びリブ１０９、１１０に押圧されるので、クランプ１００をフラットケーブル１０４に固定することができる。このクランプ１００の弾性爪部材１１１を車体の所定の位置に形成されている係止孔に圧入することで、フラットケーブル１０４を所定位置に固定させることができる。
【０００４】
また、特許文献２に開示されている第２のフラットケーブル用取付部材としてのクランプは、図７に示すように、フラットケーブル２０１の挿通係止部２０２に収容部２０３の係止突起２０４を挿通させながら、フラットケーブル２０１を収容部２０３に収容する。収容後、カバー本体２０５の他端部を上方に回動させて、ロック突起(図示せず)とロックアーム２０６とを係合してカバー本体２０５により収容部２０３の開口を完全に閉鎖させる。これにより、板部２０７、２０８によってフラットケーブル２０１が収容部２０３の底壁２０９に押圧されるので、クランプ２００をフラットケーブル２０１に固定することができる。このクランプ２００のクリップ２１０を車体の所定の位置に形成されている係止孔に圧入することで、フラットケーブル２０１を所定位置に固定させることができる。

【発明が解決しようとする課題】
ところで、ＦＦＣを配索する車体内は狭く作業し難いと共に、ＦＦＣを直線状に配索することはほとんどなくいろいろな方向に曲って配索されることがあるため、ＦＦＣの配索作業性は悪い。しかも、ＦＦＣを車体に配索する場合、１つのＦＦＣにフラットケーブル用取付部材を多数取り付けると共に、車体に配索するＦＦＣも１つではなく多数存在する。このため、車体にＦＦＣを１つずつ配索するのではなく、車体外の例えば周囲に邪魔物がない配索台上で、車体に配索する形状とほぼ同じ形状に複数のＦＦＣを配索する。この配索した各ＦＦＣの所定の個所（車体に固定する箇所）毎に予めフラットケーブル用取付部材等を取り付ける。そして、このフラットケーブル用取付部材等を取り付けたＦＦＣをそのまま車体の配索位置に位置決めする。位置決め後、各フラットケーブル用取付部材等を車体に固定することにより、ＦＦＣへのフラットケーブル用取付部材等の取付を狭い車体内で行うのではなく、車体外の広い例えば配索台上で行うので、ＦＦＣの配索作業性が向上する。
【０００７】
しかし、ＦＦＣは長くしかもいろいろな方向に曲っていることがあるため、配索台上に配索したＦＦＣの所定の箇所にフラットケーブル用取付部材を取り付けても、実際に車体にＦＦＣを位置決めしたときに、フラットケーブル用取付部材の位置が車体の例えば係止孔の位置とずれる（寸法誤差が生じる）ことがある。その場合、フラットケーブル用取付部材である前述のフラットケーブル用クランプ又はクランプをＦＦＣから一旦取り外し、再度所定の位置に取り付けなければならない。つまり、フラットケーブル用クランプ又はクランプは、ＦＦＣに固定されているため、係止部材を係止孔内から抜き出して係合を解除したり、ロック突起とロックアームとの係合を解除したりしなければならないが、通常これらの係合は解除することを前提としていないので、係合の解除を行い難い。しかも、作業する場所が車体内の狭い箇所であるとよけい作業しづらく、結果的には、ＦＦＣの車体への配索（組付け）作業性が低下することもあった。
【０００８】
そこで、本発明は、このような実情に鑑みなされたものであり、その目的は、フラットケーブルの車体等の固定体への組付け作業性を向上させることができるフラットケーブル用取付部材を提供することにある。
【０００９】
【課題を解決するための手段】
前記目的を達成するために、本発明のフラットケーブル用取付部材は、フラットケーブルを囲繞すると共にそのフラットケーブルの長手方向に対する移動を許容すべくフラットケーブルに取り付けられる矩形筒状の取付部材本体と、その取付部材本体の一方の壁部を貫通する開口から構成される装着部に、該取付部材本体の内部方向に移動可能に装着される固定部材と、該固定部材の前記取付部材本体から突出している箇所に設けられ、車体に係止される係止部と、前記固定部材に設けられ、前記係止部の前記車体への係止方向と反対の方向に沿った力により行われる前記固定部材の移動により前記取付部材本体内のフラットケーブルと係合して前記取付部材本体を前記フラットケーブルに固定する固定部と、を備え、
前記固定部が、前記装着部を貫通する基部と、その基部の前記取付部材本体外の箇所に設けられ、前記装着部を前記一方の壁部の外側から内側へのみ可撓して挿通する可撓性係合片と、前記基部の前記取付部材本体内の箇所に設けられ、前記可撓性係合片が前記装着部を挿通して前記取付部材本体内に移動したとき、該可撓性係合片を前記一方の壁部の内壁に係合させると共に、前記取付部材本体内のフラットケーブルを前記一方の壁部と向かい合う前記取付部材本体の他方の壁部の内壁に押圧して前記取付部材本体を前記フラットケーブルに固定する押圧片とからなるものである。
このように、取付部材本体をフラットケーブルに取り付けることにより、フラットケーブル用取付部材はフラットケーブルの長手方向に対する移動が許容されているので、フラットケーブルに仮係止状態に取り付けられることになる。このため、フラットケーブル用取付部材を予め取り付けたＦＦＣ等のフラットケーブルを車体に配索するときに、フラットケーブル用取付部材と車体との相対位置がずれても（寸法誤差が生じても）、フラットケーブル用取付部材をフラットケーブルの長手方向に移動させることで、容易に位置調節を行える。そして、フラットケーブル用取付部材の係止部を車体に係止させる。また、固定部材を移動させて取付部材本体内のフラットケーブルと固定部材の固定部とを係合して取付部材本体をフラットケーブルに固定する。これにより、フラットケーブルがフラットケーブル用取付部材を介して車体に固定される。したがって、ＦＦＣ等のフラットケーブルの車体への組付け作業性が向上するフラットケーブル用取付部材が得られることになる。
また、簡単な構造により取付部材本体内のフラットケーブルと固定部材の固定部とを係合させて取付部材本体をフラットケーブルに固定することができる。
また、固定部材の移動が、係止部の固定体への係止方向と反対の方向に沿った力により行われることにより、係止部を車体に係止する動作と同じ動作で取付部材本体内のフラットケーブルと固定部材の固定部とを係合することができ、フラットケーブル用取付部材をフラットケーブルに取り付けるための別途の作業（動作）を必要としない。したがって、フラットケーブルの車体への組付け作業性が一層向上することになる。
前記装着部が、矩形状に形成され、前記基部が、前記装着部の貫通方向に沿って延在する平板状に形成され、前記可撓性係合片が、前記基部の両側面にそれぞれ設けられ、該側面に対して直交する方向に沿って延在すると共に、前記取付部材本体側の面が傾斜された断面三角形の一対の矩形可撓板からなり、かつ、前記押圧片が、前記基部の端部に設けられ、該端部から前記基部の延在方向外方に沿うと共に、互いに離間する方向に湾曲された一対の矩形湾曲可撓板からなることが好ましい。
これにより、一層簡単な構造により取付部材本体内のフラットケーブルと固定部材の固定部とを係合させて取付部材本体をフラットケーブルに固定することができる。
前記固定部材の係止部と固定部との間に、前記取付部材本体の外表面に当接して前記固定部材の移動を規制すると共に、前記係止部が前記車体に係止されたとき、前記車体の表面に当接するストッパーを設けることが好ましい。
これにより、係止部の車体への係止と固定部の取付部材本体内のフラットケーブルとの係合とを確実に行える。
前記固定部材が、前記取付部材本体に着脱自在に設けられていることが好ましい。
これにより、取付部材本体をフラットケーブルに取り付ける固定部材が邪魔なときには取り外して行えるので、取付部材本体の取付を容易に行える。
【００１０】
【発明の実施の形態】
以下、本発明の実施の形態を添付図面に基づいて詳述する。
図１乃至図５は本発明のフラットケーブル用取付部材の一例が示されている図である。
【００１１】
本発明のフラットケーブル用取付部材は、図１乃至図５に示すように、フラットケーブル２に取り付けられると共に、固定体例えば車体３に固定されるものである。このフラットケーブル用取付部材１は、フラットケーブル２を囲繞すると共にそのフラットケーブル２の長手方向に対する移動を許容すべくフラットケーブル２に取り付けられる取付部材本体５と、その取付部材本体５に立設され、車体３に係止される係止部７及び取付部材本体５内のフラットケーブル２と係合して取付部材本体５をフラットケーブル２に固定する固定部８を有する固定部材６とを備えたことに特徴がある。
【００１２】
フラットケーブル２としては、可撓性を有する扁平状の電線であればどのようなものでもよく、例えば、扁平状のワイヤハーネス、フレキシブルフラットケーブル（ＦＦＣ）、フレキシブルプリント回路体（ＦＰＣ）等が挙げられる。例えば、ＦＦＣを例に挙げて説明すると、複数の銅製等の導体を所定の間隔を隔てて並列し、これら導体を並列の状態のまま２枚の塩化ビニル等の絶縁シートで挟み込む。２枚の絶縁シートが互いに接する部分を溶着（加熱接着）して一体的に融合してなるものである。このＦＦＣ２は、屈曲性や摺動性に優れるので、車体３の配線に利用されている。
【００１３】
取付部材本体５は、ＦＦＣ２にその長手方向に対する移動ができるように取り付けられるならばどのように形成してもよい。取付部材本体５としては、例えば、矩形筒体状に形成される。具体的には例えば、取付部材本体５は、幅がＦＦＣ２の幅より少し長い寸法で、高さがＦＦＣ２の厚さ以上の寸法の矩形筒体状に形成されている。すなわち、取付部材本体５は、ＦＦＣ２の表面とそれぞれ対向する２つの壁部１０，１７と、２つの側壁１８，１８とから細長の矩形筒体状に形成されている。
【００１４】
取付部材本体５（壁部１０，１７）の長さは、取付部材本体５を車体３に固定することができると共に、取付部材本体５をＦＦＣ２に固定することができる範囲から任意に設定される。
取付部材本体５（壁部１０，１７、側壁１８，１８）の厚さは、係止部７を車体３に係止するとき、及び固定部８によって取付部材本体５をＦＦＣ２に固定するときに、変形することがない寸法に形成される。
【００１５】
固定部材６は、一方の壁部（取付壁部）１０のほぼ中央部にその面に対して直交する方向（直交方向）に沿って立設されている。固定部材６は、その直交方向であって取付部材本体５の内部に向う方向（内部方向）に移動可能に設けられている。
【００１６】
固定部材６は、取付壁部１０に着脱自在に設けることが好ましく、どのように構成してもよい。固定部材６は、例えば、取付壁部１０のほぼ中央部に貫通した装着部１１を設け、この装着部１１に弾性変形等により圧入させて装着してもよいが、図示するように、装着部１１とスリット１２とを設け、スリット１２を利用して固定部材６を装着部１１に装着することが好ましい。
【００１７】
具体的には例えば、装着部１１は、細長い矩形状（ほぼスリット状）に形成され、その長手方向が取付部材本体５の長手方向（両開口部を結ぶ方向）に沿って取付壁部１０のほぼ中央部に貫通して設けられている。
装着部１１の両長辺である一対の側壁１３は、それぞれ両端部を残してコ字状に幅方向に開口されて、固定部材移動孔１４が形成されている。固定部材移動孔１４は、例えばほぼ正方形状に形成されている。
【００１８】
装着部１１の一方の端部は、その長手方向に沿って取付部材本体５の開口部まで延出して、この延出部分が固定部材６を装着部１１に案内するスリット１２として形成されている。このスリット１２を形成する両側壁の装着部側の端部には、装着部１１に装着された固定部材６がスリット１２から抜け出ないように互いに対向する側に延出する抜出防止突部１５，１５がそれぞれ設けられている。
【００１９】
固定部材６は、係止部７と固定部８とを有し、これら係止部７と固定部８とが隔壁（ストッパー）９によって仕切られていることが好ましい。固定部材６（係止部７、固定部８、ストッパー９）は、例えば合成樹脂により一体的に形成されている。
【００２０】
ストッパー９は、円形、楕円形、三角形、矩形、多角形、その他の形の平板状等どのような形状に形成してもよく、例えば、図示するように円盤状に形成される。
ストッパー９の直径は、装着部１１の長手方向の長さより長い寸法に形成することがこのましい。
【００２１】
ストッパー９の材質及び厚さは、係止部７を車体３に係止するとき、及び固定部８によって取付部材本体５をＦＦＣ２に固定するときに、車体３や取付部材本体５に当接して弾性変形や可撓し難いもの及び範囲であれば特に限定されない。例えば、ストッパー９を係止部７や固定部８より剛性を有する材質で形成してもよいし、また、係止部７や固定部８と同じ材質で形成して係止部７や固定部８と共に一体的に形成する場合には板厚を厚くするようにしてもよい。
【００２２】
ストッパー９の一方の面、つまり取付部材本体５から常に突出している面には、係止部７が設けられている。
係止部７としては、車体３の係止孔４に挿入（例えば圧入）されて係止され、フラットケーブル用取付部材１を車体３に固定し得るものであるものであればどのようなものでもよく、例えば、クリップ部２０が挙げられる。
クリップ部２０は、ストッパー９の中央部にその軸方向に沿って（表面に対して直交する方向に沿って）立設されている。
【００２３】
クリップ部２０は、例えば、ストッパー９の表面から突設された支持部２１と、その支持部２１の先端部からストッパー９方向に延在すると共に先端部に係止段部２２を有する一対の可撓性係止部２３，２３とからなる。
【００２４】
支持部２１の先端部及び可撓性係止部２３の根元部は、車体３の係止孔４に挿入し得る大きさ及び形状に形成され、例えば、ほぼ半球面状、ほぼ半楕円面状等の曲面状等に形成されている。
【００２５】
可撓性係止部２３は、外力をかけない自然状態において外表面が先端部に行くに連れて支持部２１から離間する方向に傾斜して形成されている。
可撓性係止部２３は、根元のみが支持部２１の先端部に一体的に設けられ、それ以外の支持部２１との間には空間が形成されている。これにより、可撓性係止部２３を空間方向に押圧すると（外力を作用させると）、可撓性係止部２３がその空間へ（内側へ）と付勢力に反して可撓して車体３の係止孔４を貫通し得るようになっている。
【００２６】
係止段部２２は、付勢力に反して可撓性係止部２３が可撓して車体３の係止孔４を貫通して、付勢力により元の形状に戻った、又は元の形状に戻ろうとして移動したときに、係止孔４を形成する車体３の周縁に係止するものである。このとき、ストッパー９の外表面と車体３の表面とが面接触するようにクリップ部２０の支持部２１の長さを設定することが好ましい。
【００２７】
ストッパー９の他方の面に固定部８が立設されている。
固定部８は、固定部材６を取付部材本体５内方向に移動させたときに取付部材本体５内のＦＦＣ２と係合して取付部材本体５をＦＦＣ２に固定するものである。
固定部材６の移動は、クリップ部２０の車体３への係止方向と反対の方向に沿った力により行われる（固定部材６に係止方向と反対の方向に沿った力を作用させると、固定部材６が取付部材本体５内方向に移動する）ことが好ましい。この移動は固定部８によって行われるものであり、固定部８は、どのように構成してもよい。
【００２８】
固定部８は、例えば、取付部材本体５の装着部１１に装着される基部３１と、その装着時、取付部材本体５外に位置される基部３１に設けられる可撓性係合片３２と、その装着時、取付部材本体５内に位置される基部３１に設けられる押圧片３３とからなる。
【００２９】
基部３１は、細長の矩形板状に形成されている。
基部３１の長手方向に沿った断面の形状は、取付部材本体５の装着部（固定部材移動孔１４を除いた細長い矩形状（ほぼスリット状）の装着部）１１とほぼ同じか若干小さい細長の矩形状に形成されている。
【００３０】
基部３１の長手方向に沿って延在する一側面がストッパー９の他方の面に設けられ、つまり、基部３１がストッパー９の他方の面上に立設されている。具体的には、基部３１の位置側面が、ストッパー９の他方の面上にその径方向に沿うと共に中央部とストッパー９の中心部とが同じ位置になるように設けられている。基部３１の幅（ストッパー９から立設する長さ）特にストッパー９が接する箇所から後述の可撓板３５が接する箇所までの長さは、一対の可撓板３５，３５が固定部材移動孔１４を可撓して挿通して取付部材本体５の内部に位置される寸法に形成するようにする。
【００３１】
可撓性係合片３２は、固定部８（固定部材６）装着時、取付部材本体５外に位置され、固定部８（固定部材６）をストッパー９の軸方向、クリップ部２０から固定部８側への外力により装着部１１（固定部材移動孔１４を含む装着部１１）を可撓して挿通するものである。
また、可撓性係合片３２は、取付部材本体５内に位置された状態では固定部材６に固定部８からクリップ部２０側に外力が作用しても可撓しない又は可撓しても壊れるぐらいのよほどの大きな力が作用しないかぎり装着部１１を挿通しないものでもある。
【００３２】
可撓性係合片３２としては、このように装着部１１を取付部材本体５の外側から内側へは可撓して挿通するがその逆は挿通しない（装着部１１を取付部材本体５の外側から内側へのみ可撓して挿通する）ように形成されるならばどのように形成してもよい。
可撓性係合片３２は、具体的には例えば、基部３１の両表面にそれぞれ一体的に設けられた一対の可撓板３５，３５からなる。
【００３３】
可撓板３５は、基部３１のほぼ中央部から側端部（ストッパー９に設けられた状態は先端部）より所定の長さ（取付部材本体５の板厚より若干長い寸法）中央側に近づいた位置に、その基部３１の表面に直交する方向に沿って立設されている。
すなわち、基部３１の先端部近傍が装着部１１に装着される箇所となる。
【００３４】
可撓板３５は、可撓性を有する矩形状の平板により形成されている。
可撓板３５の幅（基部３１の長手方向に沿った長さ）は、固定部材移動孔１４の対応する長さより短い寸法、好ましくは若干短い寸法に形成されている。
可撓板３５の長さは、固定部材移動孔１４の対応する長さより長い寸法であって、可撓して固定部材移動孔１４を挿通可能な寸法に形成されている。
可撓板３５のストッパー９と反対側の表面は、基部３１から離間するにしたがって漸次ストッパー９側に傾斜して、装着部１１を取付部材本体５の外側から内側に可撓して挿通すると共に、その反対方向つまり内側から外側には可撓し難くなっている。すなわち、可撓板３５は、断面三角形状の矩形状の平板により形成されている。
【００３５】
押圧片３３は、固定部８（固定部材６）装着時、取付部材本体５内に位置され、可撓板３５が取付部材本体５内に移動したときのみ、可撓してその一部が取付部材本体５の他方の壁部（第２壁部）１７の内壁に当接すると共に、その可撓した付勢力により可撓板３５を取付壁部１０の内壁に当接（係合)させるものである。このとき、取付部材本体５内にＦＦＣ２が挿通されていると、押圧片３３がＦＦＣ２を第２壁部１７の内壁に当接（押圧）して、取付部材本体５がＦＦＣ２に固定されるようになっている。
【００３６】
押圧片３３は、どのように形成してもよく、例えば、基部３１の先端部に一体的に又は個別に設けられた一対の可撓湾曲板３６，３６からなる。
可撓湾曲板３６，３６は、可撓性を有する矩形状の湾曲板により形成されている。
【００３７】
可撓湾曲板３６の幅（基部３１の長手方向に沿った長さ）は、固定部材移動孔１４の対応する長さより短い寸法、好ましくは若干短い寸法に形成されている。可撓湾曲板３６は、基部３１の先端部に、可撓板３５とほぼ同位置に設けられている。
可撓湾曲板３６は、基部３１の先端部に設けられた状態で、基部３１の延在方向外方（基部３１の延在方向であってストッパー９側の端部から先端部側への方向）に沿って延在し、延在方向前方にいくに連れて互いに離間する方向に湾曲されてる。
【００３８】
可撓湾曲板３６の形状は、基部３１の先端部に設けられた状態で、固定部材６を取付部材本体５内に移動させたときに取付部材本体５の第２壁部１７の内壁に湾曲している外面が当接して可撓し得る湾曲形状に形成され、その湾曲形状はどのような湾曲状でもよい。
可撓湾曲板３６は、例えば約９０°に湾曲されると共に、その湾曲先端部が可撓板の先端位置より基部の表面を含む平面から若干遠い位置に位置される湾曲状に形成されている。
【００３９】
可撓湾曲板３６の前方の長さ（基部３１の延在方向に沿った長さ）は、基部３１の先端部近傍を装着部１１に装着したとき、第２壁部１７の内壁との間にＦＦＣ２がその長手方向に沿って移動する、または取付部材本体５がＦＦＣ２の長手方向に沿って移動し得る空間が形成される寸法である。すなわち、一対の可撓湾曲板３６、３６と第２壁部１７の内壁との間の間隔は取付部材本体５内に挿通したＦＦＣ２の厚さより長い寸法に形成されている。また、その寸法は、可撓板３５が取付部材本体５内に移動したとき、可撓湾曲板３６が第２壁部１７の内壁に当接して可撓すると共に、その可撓した付勢力により可撓板３５を取付壁部１０の内壁に当接（係合)させる寸法でもある。
【００４０】
さて、このフラットケーブル用取付部材１を用いてＦＦＣ２を車体３に固定するには、まず、図１乃至図３に示すように、固定部材６をスリット１２を介して装着部１１に装着する。この装着は、クリップ部２０及び一対の可撓板３５，３５を取付部材本体５外に位置させると共に、一対の可撓湾曲板３６，３６を取付部材本体５内に位置させるように行う。
【００４１】
この取付部材本体５がＦＦＣ２の外周を囲繞するように、ＦＦＣ２の一端部を取付部材本体５の一方の開口部から一対の可撓湾曲板３６、３６と第２壁部１７の内壁との間に挿入して貫通させる。この挿入は、ＦＦＣ２の表面と第２壁部１７の内壁及び取付壁部１０の内壁とが対向するように行う。なお、取付部材本体５内へのＦＦＣ２の数は１つでも２つ以上でもよい。
このとき、一対の可撓湾曲板３６、３６と第２壁部１７の内壁との間の間隔は取付部材本体５内に挿通したＦＦＣ２の厚さより長い寸法に形成されているので、フラットケーブル用取付部材１はＦＦＣ２の長手方向に対する移動が許容されている。
【００４２】
この取付部材本体５をＦＦＣ２の長手方向に沿って移動（スライド移動）させるか、またはＦＦＣ２の一端部を取付部材本体５から離間する方向に引張る。または、これら取付部材本体５の移動とＦＦＣ２の引張りを両方行う。つまり、取付部材本体５のＦＦＣ２に対する位置を移動させて、取付部材本体５をＦＦＣ２の所定の位置に移動させる。
これにより、フラットケーブル用取付部材１をＦＦＣ２の所定の位置に取り付けることができる。
【００４３】
この状態では、フラットケーブル用取付部材１はＦＦＣ２の長手方向に対する移動が許容されているので、ＦＦＣ２に仮係止状態に取り付けられることになる。このため、フラットケーブル用取付部材１を予めＦＦＣ２に取り付けてから、このＦＦＣ２を車体３に位置決めしたときに、フラットケーブル用取付部材１のクリップ部２０と車体３の係止孔４との相対位置がずれていても（寸法誤差が生じていても）、フラットケーブル用取付部材１をＦＦＣ２から取り外すことなく、フラットケーブル用取付部材１をＦＦＣ２の長手方向に沿って簡単に移動させることができ、フラットケーブル用取付部材１の取付位置を容易に調節することができる。
【００４４】
そして、フラットケーブル用取付部材１のクリップ部２０を、図２に示すように、車体３の係止孔４に突き合わせ、この状態のままフラットケーブル用取付部材１を車体３に接触させる。つまり、クリップ部２０を係止孔４に挿入するようにフラットケーブル用取付部材１を車体３方向に移動させる。
【００４５】
すると、クリップ部２０の支持部２１の先端部及び可撓性係止部２３の根元部が係止孔４内に入る。さらに、フラットケーブル用取付部材１が車体３に近づくと、可撓性係止部２３が係止孔４を形成する車体３に接触して、支持部２１方向に付勢力に反して可撓して、係止孔４内に進入する。係止段部２２を除いた可撓性係止部２３が係止孔４を貫通すると、可撓性係止部２３は付勢力により元の形状に戻ろうとして移動し、図４及び図５に示すように、係止段部２２が係止孔４を形成する車体３の周縁に係止する。このとき、取付部材本体５の第１壁部１０の外表面が車体３の表面に接触してフラットケーブル用取付部材１が車体３に固定される。
【００４６】
また、クリップ部２０を係止孔４に挿入するようにフラットケーブル用取付部材１を車体３方向に移動させたとき、固定部材移動孔１４を形成する壁が一対の可撓板３５，３５に当接して、一対の可撓板３５，３５を押圧する。一対の可撓板３５，３５は、付勢力に反してストッパー９側に可撓して、装着部１１（固定部材移動孔１４を含む装着部１１）を挿通し、それぞれ取付部材本体５内に入り、取付壁部１０の外表面がストッパー９に当接する。このように、固定部材６が取付部材本体５内へと移動すると、一対の可撓湾曲板３６，３６がＦＦＣ２の両側部近傍にそれぞれ接触して、ＦＦＣ２を第２壁部１７の内壁に押圧しつつその押圧力により付勢力に抗して可撓する。そして、固定部材６への外力が作用しなくなると、可撓した一対の可撓湾曲板３６，３６の付勢力により一対の可撓板３５，３５が取付壁部１０の内壁に当接（係合)される。このとき、一対の可撓湾曲板３６，３６は付勢力に抗して可撓しており、その付勢力によりＦＦＣ２が第２壁部１７の内壁に押圧されている。すなわち、ＦＦＣ２は、一対の可撓湾曲板３６，３６と第２壁部１７の内壁とによって挟持されて、フラットケーブル用取付部材１がＦＦＣ２に固定される。
【００４７】
なお、クリップ部２０の車体への固定とフラットケーブル用取付部材１のＦＦＣ２への固定とは、一概に言えないが、可撓性係止部２３の付勢力と一対の可撓板３５，３５及び一対の可撓湾曲板３６，３６の付勢力とが同じ場合には、ほぼ同時に行われ、どちらかの付勢力が強い場合には弱い方の固定が先に行われる。
【００４８】
したがって、本発明のフラットケーブル用取付部材１は、ＦＦＣ２に取り付けた後に、その位置を容易に調節することができるので、ＦＦＣ２の車体３への組付け作業性を向上させることができるものである。
【００４９】
また、クリップ部２０を係止孔４に挿入するようにフラットケーブル用取付部材１を車体３方向に移動させる動作により、クリップ部２０の車体３への固定とフラットケーブル用取付部材１のＦＦＣ２への固定とが行われるので、フラットケーブル用取付部材１をＦＦＣ２に取り付けるための別の作業（動作)が必要ない。よって、ＦＦＣ２の車体３への組付け作業性を一層向上させることができる。
【００５０】
また、固定部８が、基部３１と一対の可撓板３５，３５と一対の可撓湾曲板３６，３６とからなることにより、固定部８を簡単な構造に形成することができる。また、ばね等の他の部材を用いることなく簡単な構造により取付部材本体５内のＦＦＣ２を第２壁部１７の内壁に押圧させて取付部材本体５をＦＦＣ２に固定することができる。
【００５１】
また、クリップ部２０と固定部８との間にストッパー９を設けたので、クリップ部２０の車体３への固定と取付部材本体５のＦＦＣ２への固定とを確実に行える。
また、固定部材６が取付部材本体５に着脱自在に設けられていると、ＦＦＣ２の長手方向に沿って取付部材本体５を移動（スライド移動）させるときに、固定部材６を装着しない状態で取付部材本体５を移動させられるので、取付部材本体５のＦＦＣ２への取付を容易に行える。また、固定部材６や取付部材本体５が壊れたときには、フラットケーブル用取付部材１全部を交換しなくても必要な部材のみを交換すればよい。
【００５２】
【発明の効果】
以上により、フラットケーブルの固定体への組付け作業性が向上するフラットケーブル用取付部材が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a flat cable mounting member for fixing a flat cable such as a flat wire harness, a flexible flat cable (FFC), and a flexible printed circuit body (FPC) to a fixed body such as a vehicle body.
[0002]
[Prior art]
A large number of electronic devices and machine parts are mounted on the automobile for various controls. These electronic devices and the like are electrically connected by a flat cable having flexibility such as a flat wire harness, a flexible flat cable (FFC), and a flexible printed circuit body (FPC). In this way, a large number of FFCs, for example, are arranged in the vehicle, and these FFCs are predetermined using, for example, a flat cable mounting member so as not to interfere with surrounding parts or to be bitten by movable parts. Each part is fixed to the car body.
[0003]
Various flat cable mounting members have been proposed (see, for example, Patent Documents 1 and 2).
For example, as shown in FIG. 6, a flat cable clamp as a first flat cable mounting member disclosed in Patent Document 1 is obtained by extracting the locking member 101 from the locking hole 102. The flat cable 104 is inserted from the lower side toward the lower side of the overhang member 103, and one side end of the flat cable 104 is inserted into the holding portion 105. Next, after positioning the other side end of the flat cable 104 on the clamping portion 106, the locking member 101 is inserted into the locking hole 102. Accordingly, the flat cable 104 is pressed against the width elastic portion 108 and the ribs 109 and 110 by the spring piece 107, so that the clamp 100 can be fixed to the flat cable 104. The flat cable 104 can be fixed at a predetermined position by press-fitting the elastic claw member 111 of the clamp 100 into a locking hole formed at a predetermined position of the vehicle body.
[0004]
In addition, the clamp as the second flat cable mounting member disclosed in Patent Document 2 is inserted through the locking protrusion 204 of the housing portion 203 into the insertion locking portion 202 of the flat cable 201 as shown in FIG. Then, the flat cable 201 is accommodated in the accommodating portion 203. After the housing, the other end of the cover main body 205 is rotated upward to engage a lock protrusion (not shown) and the lock arm 206 to completely close the opening of the housing 203 by the cover main body 205. Accordingly, the flat cable 201 is pressed against the bottom wall 209 of the housing portion 203 by the plate portions 207 and 208, so that the clamp 200 can be fixed to the flat cable 201. The flat cable 201 can be fixed at a predetermined position by press-fitting the clip 210 of the clamp 200 into a locking hole formed at a predetermined position of the vehicle body.

[Problems to be solved by the invention]
By the way, the inside of the vehicle body in which the FFC is routed is difficult to work narrowly, and since the FFC is rarely routed in a straight line and may be routed in various directions, the routing workability of the FFC is bad. In addition, when the FFC is routed to the vehicle body, many flat cable attachment members are attached to one FFC, and there are many FFCs wired to the vehicle body instead of one. For this reason, instead of routing FFCs one by one on the vehicle body, a plurality of FFCs are routed in a shape substantially the same as that to be installed on the vehicle body on a wiring stand outside the vehicle body, for example, without any obstacles To do. A flat cable attachment member or the like is attached in advance to each predetermined portion (location to be fixed to the vehicle body) of each routed FFC. Then, the FFC to which the flat cable mounting member and the like are mounted is positioned as it is in the car body routing position. After positioning, each flat cable mounting member or the like is fixed to the vehicle body, so that the flat cable mounting member or the like is not mounted in the narrow vehicle body, but on a wide cable platform outside the vehicle body, for example. Therefore, the workability of FFC routing is improved.
[0007]
However, since the FFC is long and may be bent in various directions, the FFC is actually positioned on the vehicle body even when the flat cable mounting member is attached to a predetermined portion of the FFC routed on the routing table. Sometimes, the position of the flat cable mounting member is displaced from the position of, for example, the locking hole of the vehicle body (a dimensional error occurs). In that case, the flat cable clamp or clamp described above, which is a flat cable mounting member, must be once removed from the FFC and mounted again at a predetermined position. In other words, since the flat cable clamp or clamp is fixed to the FFC, the engagement member can be removed from the engagement hole to release the engagement, or the engagement between the lock protrusion and the lock arm can be released. However, since it is not premised that these engagements are usually released, it is difficult to release the engagements. In addition, it is difficult to work if the place where the work is performed is a narrow place in the vehicle body. As a result, the workability of assembling (assembling) the FFC to the vehicle body may be reduced.
[0008]
Therefore, the present invention has been made in view of such circumstances, and an object thereof is to provide a flat cable mounting member capable of improving the workability of assembling the flat cable to a fixed body such as a vehicle body. There is.

  In this way, by attaching the attachment member main body to the flat cable, the flat cable attachment member is allowed to move in the longitudinal direction of the flat cable, so that it is attached to the flat cable in a temporarily locked state. For this reason, a flat cable such as FFC with a flat cable mounting member attached in advance is used.BodyWhen wiring to the flat cable mounting memberBodyEven if the relative position is shifted (even if a dimensional error occurs), the position can be easily adjusted by moving the flat cable mounting member in the longitudinal direction of the flat cable.

In addition, the movement of the fixing member is performed by a force along the direction opposite to the locking direction of the locking portion to the fixed body, so that the mounting member main body is operated in the same manner as the locking operation of the locking portion to the vehicle body. The inner flat cable and the fixing portion of the fixing member can be engaged with each other, and a separate operation (operation) for attaching the flat cable mounting member to the flat cable is not required.

[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
1 to 5 are views showing an example of a flat cable mounting member of the present invention.
[0011]
As shown in FIGS. 1 to 5, the flat cable attachment member of the present invention is attached to the flat cable 2 and fixed to a fixed body, for example, the vehicle body 3. The flat cable mounting member 1 surrounds the flat cable 2 and is erected on the mounting member main body 5 to be attached to the flat cable 2 so as to allow movement of the flat cable 2 in the longitudinal direction. And a fixing member 6 having a fixing portion 8 that is engaged with the flat cable 2 in the attachment member main body 5 and is engaged with the flat cable 2 in the attachment member main body 5 to fix the attachment member main body 5 to the flat cable 2. There is a special feature.
[0012]
The flat cable 2 may be any flat electric wire having flexibility, and examples thereof include a flat wire harness, a flexible flat cable (FFC), and a flexible printed circuit body (FPC). It is done. For example, a description will be given by taking FFC as an example. A plurality of conductors made of copper or the like are arranged in parallel at a predetermined interval, and these conductors are sandwiched between two insulating sheets such as vinyl chloride in a parallel state. A portion where two insulating sheets are in contact with each other is welded (heat-bonded) and integrally fused. The FFC 2 is used for wiring of the vehicle body 3 because it has excellent flexibility and slidability.
[0013]
The attachment member body 5 may be formed in any manner as long as it can be attached to the FFC 2 so as to be movable in the longitudinal direction. The attachment member main body 5 is formed in, for example, a rectangular cylindrical shape. Specifically, for example, the attachment member body 5 is formed in a rectangular cylindrical shape having a width slightly longer than the width of the FFC 2 and a height not less than the thickness of the FFC 2. That is, the attachment member main body 5 is formed in an elongated rectangular cylindrical shape from the two wall portions 10 and 17 and the two side walls 18 and 18 respectively facing the surface of the FFC 2.
[0014]
The length of the attachment member main body 5 (wall portions 10, 17) is arbitrarily set from the range in which the attachment member main body 5 can be fixed to the vehicle body 3 and the attachment member main body 5 can be fixed to the FFC 2. .
The thickness of the mounting member main body 5 (wall portions 10, 17 and side walls 18, 18) is such that when the locking portion 7 is locked to the vehicle body 3, and when the mounting member main body 5 is fixed to the FFC 2 by the fixing portion 8. The dimensions are such that they do not deform.
[0015]
The fixing member 6 is erected at a substantially central portion of one wall portion (mounting wall portion) 10 along a direction (orthogonal direction) orthogonal to the surface. The fixing member 6 is provided so as to be movable in the orthogonal direction to the inside of the mounting member body 5 (internal direction).
[0016]
The fixing member 6 is preferably provided detachably on the mounting wall 10 and may be configured in any manner. For example, the fixing member 6 may be provided with a mounting portion 11 penetrating substantially at the center of the mounting wall portion 10 and may be press-fitted to the mounting portion 11 by elastic deformation or the like. 11 and the slit 12 are provided, and the fixing member 6 is preferably mounted on the mounting portion 11 using the slit 12.
[0017]
Specifically, for example, the mounting portion 11 is formed in an elongated rectangular shape (substantially slit shape), and the longitudinal direction of the mounting wall portion 10 extends along the longitudinal direction of the mounting member body 5 (the direction connecting both openings). It is provided almost through the center.
A pair of side walls 13 that are both long sides of the mounting portion 11 are opened in the width direction in a U shape leaving both ends, and a fixing member moving hole 14 is formed. The fixed member moving hole 14 is formed in, for example, a substantially square shape.
[0018]
One end of the mounting portion 11 extends to the opening of the mounting member main body 5 along its longitudinal direction, and this extended portion is formed as a slit 12 that guides the fixing member 6 to the mounting portion 11. . At the end of the both side walls forming the slit 12 on the mounting portion side, the pull-out preventing protrusions 15 extending to the opposite sides so that the fixing member 6 mounted on the mounting portion 11 does not come out of the slit 12. , 15 are provided.
[0019]
The fixing member 6 has a locking part 7 and a fixing part 8, and the locking part 7 and the fixing part 8 are preferably partitioned by a partition wall (stopper) 9. The fixing member 6 (the locking portion 7, the fixing portion 8, and the stopper 9) is integrally formed of, for example, a synthetic resin.
[0020]
The stopper 9 may be formed in any shape such as a circular shape, an elliptical shape, a triangular shape, a rectangular shape, a polygonal shape, or other flat plate shape. For example, the stopper 9 is formed in a disc shape as illustrated.
The diameter of the stopper 9 is preferably formed to be longer than the length of the mounting portion 11 in the longitudinal direction.
[0021]
The material and thickness of the stopper 9 are in contact with the vehicle body 3 and the mounting member body 5 when the locking portion 7 is locked to the vehicle body 3 and when the mounting member body 5 is fixed to the FFC 2 by the fixing portion 8. It is not particularly limited as long as it is difficult to be elastically deformed or flexible and has a range. For example, the stopper 9 may be formed of a material that is more rigid than the locking portion 7 or the fixing portion 8, or may be formed of the same material as the locking portion 7 or the fixing portion 8. In the case of being integrally formed with 8, the plate thickness may be increased.
[0022]
A locking portion 7 is provided on one surface of the stopper 9, that is, the surface that always protrudes from the attachment member main body 5.
As the locking portion 7, any locking portion 7 can be inserted (for example, press-fitted) into the locking hole 4 of the vehicle body 3 and locked to fix the flat cable mounting member 1 to the vehicle body 3. For example, the clip part 20 is mentioned.
The clip portion 20 is erected along the axial direction (along the direction orthogonal to the surface) at the central portion of the stopper 9.
[0023]
The clip portion 20 includes, for example, a pair of movable portions 21 that protrude from the surface of the stopper 9 and that extend from the distal end portion of the support portion 21 toward the stopper 9 and have a locking step portion 22 at the distal end portion. It consists of flexible locking parts 23, 23.
[0024]
The distal end portion of the support portion 21 and the base portion of the flexible locking portion 23 are formed in a size and shape that can be inserted into the locking hole 4 of the vehicle body 3, for example, a substantially hemispherical shape or a substantially semi-elliptical surface shape. It is formed in a curved surface shape.
[0025]
The flexible locking portion 23 is formed so as to be inclined in a direction away from the support portion 21 as the outer surface goes to the tip portion in a natural state where no external force is applied.
Only the base of the flexible locking portion 23 is integrally provided at the distal end portion of the support portion 21, and a space is formed between the other support portions 21. Thus, when the flexible locking portion 23 is pressed in the space direction (when an external force is applied), the flexible locking portion 23 is flexed against the space (inward) against the biasing force. 3 through-holes 4 can be penetrated.
[0026]
The locking step 22 is returned to its original shape by the urging force, or the flexible locking portion 23 is flexed through the locking hole 4 of the vehicle body 3 against the urging force. When it moves to return to, it locks to the periphery of the vehicle body 3 that forms the locking hole 4. At this time, it is preferable to set the length of the support portion 21 of the clip portion 20 so that the outer surface of the stopper 9 and the surface of the vehicle body 3 are in surface contact.
[0027]
A fixing portion 8 is erected on the other surface of the stopper 9.
The fixing portion 8 engages with the FFC 2 in the mounting member main body 5 to fix the mounting member main body 5 to the FFC 2 when the fixing member 6 is moved inward in the mounting member main body 5.
The movement of the fixing member 6 is performed by a force along a direction opposite to the locking direction of the clip portion 20 to the vehicle body 3 (when a force along the direction opposite to the locking direction is applied to the fixing member 6, It is preferable that the fixing member 6 moves inward in the mounting member main body 5). This movement is performed by the fixing unit 8, and the fixing unit 8 may be configured in any way.
[0028]
The fixing portion 8 includes, for example, a base 31 that is mounted on the mounting portion 11 of the mounting member main body 5, and a flexible engagement piece 32 that is provided on the base 31 that is positioned outside the mounting member main body 5 at the time of mounting. At the time of mounting, it comprises a pressing piece 33 provided on the base 31 located in the mounting member main body 5.
[0029]
The base 31 is formed in an elongated rectangular plate shape.
The shape of the cross section along the longitudinal direction of the base 31 is an elongated shape that is substantially the same as or slightly smaller than the mounting portion 11 of the mounting member main body 5 (elongated rectangular (substantially slit-shaped) mounting portion excluding the fixing member moving hole 14) 11. It is formed in a rectangular shape.
[0030]
One side surface extending along the longitudinal direction of the base portion 31 is provided on the other surface of the stopper 9, that is, the base portion 31 is erected on the other surface of the stopper 9. Specifically, the position side surface of the base portion 31 is provided on the other surface of the stopper 9 along the radial direction so that the center portion and the center portion of the stopper 9 are at the same position. The width of the base portion 31 (length standing from the stopper 9), particularly the length from the position where the stopper 9 is in contact to the position where the later-described flexible plate 35 is in contact, is the pair of flexible plates 35, 35 being fixed member moving holes 14. Are formed so as to be dimensioned to be positioned inside the attachment member main body 5 by being inserted through with flexibility.
[0031]
The flexible engagement piece 32 is positioned outside the attachment member main body 5 when the fixing portion 8 (fixing member 6) is mounted, and the fixing portion 8 (fixing member 6) is fixed to the axial direction of the stopper 9 from the clip portion 20 to the fixing portion. The mounting portion 11 (the mounting portion 11 including the fixed member moving hole 14) is inserted flexibly by an external force to the 8th side.
Further, the flexible engaging piece 32 is not flexible or flexible even when an external force is applied to the fixing member 6 from the fixing portion 8 to the clip portion 20 side in a state where the flexible engaging piece 32 is positioned in the attachment member main body 5. The mounting portion 11 is not inserted unless such a large force as to break is applied.
[0032]
As the flexible engagement piece 32, the mounting portion 11 is thus inserted from the outside to the inside of the mounting member main body 5 in a flexible manner, but the reverse is not inserted (the mounting portion 11 is inserted outside the mounting member main body 5. It may be formed in any way as long as it is formed so as to be flexibly inserted only from the inside to the inside.
Specifically, the flexible engagement piece 32 includes, for example, a pair of flexible plates 35 and 35 that are integrally provided on both surfaces of the base portion 31.
[0033]
The flexible plate 35 approaches a central side from a substantially central portion of the base portion 31 to a central end side of a predetermined length (a dimension slightly longer than the plate thickness of the mounting member main body 5) from a side end portion (a state provided at the stopper 9 is a tip portion). It is erected along the direction perpendicular to the surface of the base 31 at the position.
That is, the vicinity of the distal end portion of the base portion 31 is a place where the mounting portion 11 is mounted.
[0034]
The flexible plate 35 is formed of a rectangular flat plate having flexibility.
The width of the flexible plate 35 (the length along the longitudinal direction of the base portion 31) is shorter than the corresponding length of the fixed member moving hole 14, and preferably slightly shorter.
The length of the flexible plate 35 is longer than the corresponding length of the fixed member moving hole 14, and is formed to have a size that can be inserted through the fixed member moving hole 14 flexibly.
The surface of the flexible plate 35 opposite to the stopper 9 is gradually inclined toward the stopper 9 as it is separated from the base 31, and the mounting portion 11 is flexibly inserted from the outside to the inside of the mounting member body 5. In the opposite direction, that is, from the inside to the outside, it is difficult to be flexible. That is, the flexible plate 35 is formed by a rectangular flat plate having a triangular cross section.
[0035]
The pressing piece 33 is positioned in the attachment member main body 5 when the fixing portion 8 (fixing member 6) is mounted, and is flexible and partly attached only when the flexible plate 35 moves into the attachment member main body 5. While abutting against the inner wall of the other wall portion (second wall portion) 17 of the member main body 5, the flexible plate 35 abuts (engages) with the inner wall of the mounting wall portion 10 by its flexible urging force. is there. At this time, if the FFC 2 is inserted into the mounting member main body 5, the pressing piece 33 abuts (presses) the FFC 2 against the inner wall of the second wall portion 17 so that the mounting member main body 5 is fixed to the FFC 2. It has become.
[0036]
The pressing piece 33 may be formed in any manner, and includes, for example, a pair of flexible curved plates 36 and 36 provided integrally or individually at the distal end portion of the base portion 31.
The flexible curved plates 36 and 36 are formed of a rectangular curved plate having flexibility.
[0037]
The width of the flexible curved plate 36 (the length along the longitudinal direction of the base portion 31) is shorter than the corresponding length of the fixed member moving hole 14, and preferably slightly shorter. The flexible curved plate 36 is provided at the front end portion of the base portion 31 at substantially the same position as the flexible plate 35.
The flexible curved plate 36 is provided at the distal end portion of the base portion 31 and extends outward in the extending direction of the base portion 31 (the extending direction of the base portion 31 in the direction from the end portion on the stopper 9 side to the distal end portion side). ) And curved in a direction away from each other as it goes forward in the extending direction.
[0038]
The shape of the flexible bending plate 36 is curved at the inner wall of the second wall portion 17 of the mounting member main body 5 when the fixing member 6 is moved into the mounting member main body 5 in a state of being provided at the distal end portion of the base portion 31. It is formed in a curved shape that can be flexed by contacting the outer surface, and the curved shape may be any curved shape.
The flexible curved plate 36 is curved, for example, at about 90 °, and is formed in a curved shape in which the curved distal end portion is located at a position slightly distant from the plane including the surface of the base portion from the distal end position of the flexible plate. .
[0039]
The front length of the flexible curved plate 36 (the length along the extending direction of the base portion 31) is between the inner wall of the second wall portion 17 when the vicinity of the distal end portion of the base portion 31 is mounted on the mounting portion 11. The FFC 2 moves along the longitudinal direction of the FFC 2 or the space in which the attachment member main body 5 can move along the longitudinal direction of the FFC 2 is formed. That is, the distance between the pair of flexible curved plates 36 and 36 and the inner wall of the second wall portion 17 is formed to be longer than the thickness of the FFC 2 inserted into the attachment member body 5. In addition, when the flexible plate 35 moves into the mounting member main body 5, the flexible curved plate 36 comes into contact with the inner wall of the second wall portion 17 to be flexible, and the flexible urging force It is also a size that allows the flexible plate 35 to abut (engage) with the inner wall of the mounting wall portion 10.
[0040]
In order to fix the FFC 2 to the vehicle body 3 using the flat cable mounting member 1, first, the fixing member 6 is mounted on the mounting portion 11 via the slit 12, as shown in FIGS. This mounting is performed such that the clip portion 20 and the pair of flexible plates 35 and 35 are positioned outside the attachment member main body 5 and the pair of flexible curved plates 36 and 36 are positioned within the attachment member main body 5.
[0041]
One end portion of the FFC 2 is disposed between one opening of the attachment member main body 5 between the pair of flexible curved plates 36 and 36 and the inner wall of the second wall portion 17 so that the attachment member main body 5 surrounds the outer periphery of the FFC 2. Insert into and penetrate. This insertion is performed so that the surface of the FFC 2 faces the inner wall of the second wall portion 17 and the inner wall of the mounting wall portion 10. In addition, the number of FFC2 in the attachment member main body 5 may be one or two or more.
At this time, the distance between the pair of flexible curved plates 36 and 36 and the inner wall of the second wall portion 17 is formed to be longer than the thickness of the FFC 2 inserted into the mounting member main body 5. The attachment member 1 is allowed to move in the longitudinal direction of the FFC 2.
[0042]
The mounting member body 5 is moved (slided) along the longitudinal direction of the FFC 2 or one end of the FFC 2 is pulled away from the mounting member body 5. Alternatively, both the movement of the attachment member body 5 and the pulling of the FFC 2 are performed. That is, the position of the attachment member body 5 with respect to the FFC 2 is moved, and the attachment member body 5 is moved to a predetermined position of the FFC 2.
Thereby, the attachment member 1 for flat cables can be attached to the predetermined position of FFC2.
[0043]
In this state, the flat cable attachment member 1 is allowed to move in the longitudinal direction of the FFC 2 and is thus attached to the FFC 2 in a temporarily locked state. Therefore, when the flat cable attachment member 1 is attached to the FFC 2 in advance and the FFC 2 is positioned on the vehicle body 3, the relative position between the clip portion 20 of the flat cable attachment member 1 and the locking hole 4 of the vehicle body 3. Can be easily moved along the longitudinal direction of the FFC 2 without removing the flat cable mounting member 1 from the FFC 2. The mounting position of the flat cable mounting member 1 can be easily adjusted.
[0044]
Then, as shown in FIG. 2, the clip portion 20 of the flat cable mounting member 1 is brought into contact with the locking hole 4 of the vehicle body 3, and the flat cable mounting member 1 is brought into contact with the vehicle body 3 in this state. That is, the flat cable mounting member 1 is moved in the direction of the vehicle body 3 so that the clip portion 20 is inserted into the locking hole 4.
[0045]
Then, the distal end portion of the support portion 21 of the clip portion 20 and the root portion of the flexible locking portion 23 enter the locking hole 4. Further, when the flat cable mounting member 1 approaches the vehicle body 3, the flexible locking portion 23 comes into contact with the vehicle body 3 forming the locking hole 4 and flexes against the biasing force in the direction of the support portion 21. And enters the locking hole 4. When the flexible locking portion 23 excluding the locking step portion 22 penetrates the locking hole 4, the flexible locking portion 23 moves to return to the original shape by the urging force, and FIG. 4 and FIG. As shown, the locking step 22 is locked to the periphery of the vehicle body 3 forming the locking hole 4. At this time, the outer surface of the first wall portion 10 of the attachment member body 5 contacts the surface of the vehicle body 3, and the flat cable attachment member 1 is fixed to the vehicle body 3.
[0046]
Further, when the flat cable mounting member 1 is moved in the direction of the vehicle body 3 so that the clip portion 20 is inserted into the locking hole 4, the walls forming the fixing member moving hole 14 are formed on the pair of flexible plates 35, 35. The pair of flexible plates 35 and 35 are pressed against each other. The pair of flexible plates 35, 35 are flexed toward the stopper 9 against the urging force, inserted through the mounting portion 11 (the mounting portion 11 including the fixed member moving hole 14), and are respectively inserted into the mounting member main body 5. The outer surface of the mounting wall 10 comes into contact with the stopper 9. Thus, when the fixing member 6 moves into the mounting member main body 5, the pair of flexible curved plates 36 and 36 come in contact with the vicinity of both side portions of the FFC 2, and presses the FFC 2 against the inner wall of the second wall portion 17. However, it is flexible against the urging force by the pressing force. When the external force is no longer applied to the fixing member 6, the pair of flexible plates 35, 35 are brought into contact with the inner wall of the mounting wall portion 10 by the urging force of the pair of flexible bending plates 36, 36. Are combined). At this time, the pair of flexible curved plates 36 and 36 are flexible against the urging force, and the FFC 2 is pressed against the inner wall of the second wall portion 17 by the urging force. That is, the FFC 2 is sandwiched between the pair of flexible curved plates 36 and 36 and the inner wall of the second wall portion 17, and the flat cable mounting member 1 is fixed to the FFC 2.
[0047]
The fixing of the clip portion 20 to the vehicle body and the fixing of the flat cable mounting member 1 to the FFC 2 cannot be generally described, but the urging force of the flexible locking portion 23 and the pair of flexible plates 35, 35. When the urging forces of the pair of flexible curved plates 36 and 36 are the same, the urging forces are performed almost simultaneously, and when either urging force is strong, the weaker one is fixed first.
[0048]
Therefore, since the position of the flat cable mounting member 1 of the present invention can be easily adjusted after being mounted on the FFC 2, the workability of assembling the FFC 2 to the vehicle body 3 can be improved. .
[0049]
Further, the flat cable mounting member 1 is fixed to the vehicle body 3 and the flat cable mounting member 1 is moved to the FFC 2 by moving the flat cable mounting member 1 in the direction of the vehicle body 3 so as to insert the clip portion 20 into the locking hole 4. Therefore, another work (operation) for attaching the flat cable attachment member 1 to the FFC 2 is not necessary. Therefore, the workability of assembling the FFC 2 to the vehicle body 3 can be further improved.
[0050]
Further, since the fixing portion 8 includes the base portion 31, the pair of flexible plates 35 and 35, and the pair of flexible bending plates 36 and 36, the fixing portion 8 can be formed in a simple structure. Further, the FFC 2 in the attachment member body 5 can be pressed against the inner wall of the second wall portion 17 by a simple structure without using other members such as a spring, and the attachment member body 5 can be fixed to the FFC 2.
[0051]
Further, since the stopper 9 is provided between the clip portion 20 and the fixing portion 8, the clip portion 20 can be fixed to the vehicle body 3 and the attachment member body 5 can be fixed to the FFC 2 with certainty.
In addition, when the fixing member 6 is detachably provided on the mounting member main body 5, when the mounting member main body 5 is moved (slidably moved) along the longitudinal direction of the FFC 2, the fixing member 6 is not mounted. Since the member main body 5 can be moved, the attachment member main body 5 can be easily attached to the FFC 2. Further, when the fixing member 6 or the mounting member main body 5 is broken, only the necessary members need be replaced without replacing the entire flat cable mounting member 1.
[0052]
