【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9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10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、フラットケーブルに取り付けられると共に、車体に固定されるフラットケーブル用取付部材であって、
前記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前記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、該取付部材本体の一方の壁部に設けられて前記車体に係止される係止部材と、該取付部材本体の前記一方の壁部と対向する他方の壁部に形成されたスリットの最奥部からなる装着部に装着され、該取付部材本体外に位置される操作部を回動させて、前記取付部材本体内のフラットケーブルを取付部材本体の前記一方の壁部の内壁に押圧して取付部材本体をフラットケーブルに固定する固定部材と、を備え、
前記固定部材が、前記装着部を貫通する軸部と、その軸部の取付部材本体外に位置される端部に取り付けられた前記操作部と、前記軸部の他方の端部に一方の表面が取り付けられ、他方の表面で取付部材本体内のフラットケーブルを取付部材本体の前記一方の壁部の内壁に押圧する押圧板と、前記押圧板の前記一方の表面に形成され、前記取付部材本体の前記他方の壁部に設けられた仮係止部と係合して前記取付部材本体のフラットケーブルの長手方向に対する移動を許容すると共に、前記回動により前記仮係止部との係合が解除されて取付部材本体の前記他方の壁部に設けられた本係止部に係止される押圧部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、操作部を回動させると、固定部材によって、取付部材本体内のフラットケーブルが取付部材本体の内壁に押圧されて取付部材本体がフラットケーブルに固定される。
したがって、FFC等のフラットケーブルの車体等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ことになる。
また、係止部材と固定部材とが取付部材本体の対向する壁部に別々に設けられているため、係止部材により取付部材本体を固定体に係止させて固定した後に、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。このため、取付部材本体を固定体に固定した後でも取付部材本体をフラットケーブルに固定する位置の調節を行えるので、フラットケーブルの固定体への組付け作業性が一層向上することになる。
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内のフラットケーブルを取付部材本体の内壁に押圧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。
前記軸部が円柱状に形成され、前記操作部が直線細長状に形成され、この操作部の長手方向ほぼ中央部に、この長手方向と前記軸部の軸方向とが直交するように軸部の一端部が取り付けられ、前記押圧板が、円盤状に形成され、この押圧板の中央部に、該押圧板の軸方向と前記軸部の軸方向とがほぼ同軸上になるように軸部の他端部が取り付けられ、前記押圧部が、前記押圧板の前記軸部が取り付けられた表面に、その周方向に沿って延在する円弧状の係合突部であることが好ましい。
これにより、固定部材を簡単な構造に形成することができる。
前記押圧部の前記回動方向前方が、前方にいくに連れて漸次前記押圧板の前記一方の表面側に傾斜された傾斜面として形成され、この傾斜面の傾斜先端部が前記押圧板の前記一方の表面に達していることが好ましい。
これにより、操作部を回動させて押圧部を仮係止部から抜け出すとき、その仮係止部を形成する壁部に接する箇所である押圧部の回動方向前方が傾斜面として形成されているので、押圧部が仮係止部から抜け出し易く、容易に操作部を回動させることができる。したがって、固定部材を容易に仮係止状態から本係止状態に移行させることができる。
前記本係止部が、前記操作部を約90°回動させたときに前記押圧部が係止されるべく前記取付部材本体の前記他方の壁部に設けられていることが好ましい。
これにより、操作部が例えば直線細長状に形成されていると、仮係止状態と本係止状態とでは操作部の向きが90°異なるため、取付部材本体がフラットケーブルに固定されているか否かを容易に把握することができる。
【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6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6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(フラットケーブル2の一部全周を囲繞する)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に設けられ、該取付部材本体5外に位置される操作部31を回動させて、前記取付部材本体5内のフラットケーブル2を取付部材本体5の内壁10aに押圧して取付部材本体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、図1乃至図7に示すように、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10,11と、2つの側壁12,12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10,11)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10,11側壁12,12)の厚さは、係止部材7を車体3に係止するとき、及び固定部材6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】
取付部材本体5の壁部の一方の壁部(第1壁部)10には係止部材7が設けられている。
係止部材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、第1壁部10の中央部にその表面に対して直交する方向に沿って立設されている。
【0016】
クリップ部20は、例えば、第1壁部10の表面から突設された支持部21と、その支持部21の先端部から第1壁部10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。
【0017】
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。
【0018】
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。
【0019】
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、第1壁部10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。
【0020】
固定部材6は、取付部材本体5の他方の壁部(第1壁部と対向する壁部(第2壁部))11のほぼ中央部の装着部13に装着されている(設けられている)。第2壁部11には、スリット14が設けられている。このスリット14は、第2壁部11の一方の端部のほぼ中央部から側壁12の延在方向に沿ってそのほぼ中央部まで延在している。スリット14の最奥部は、半円状に形成されて、この部分が装着部13として形成されている。なお、装着部13に装着された固定部材6がスリット14から抜け出ないように、スリット14を区画形成する両側壁の装着部近傍に、互いに対向する側に延出する抜出防止突部(図示せず)をそれぞれ設けるようにしてもよい。
【0021】
第2壁部11の装着部13の周囲には、仮係止部16が設けられている。仮係止部16は、第2壁部11の厚さが例えば特に厚い場合には溝状に形成してもよいが、好ましくは、第2壁部11を貫通する孔状に形成することがよい。また、仮係止部16は、どのような形状であってもよく、例えば、装着部13と同軸上の円弧状に形成することが好ましい。
仮係止部16の数は、固定部材6の押圧部の数に応じて決められるが、例えば、2つである。すなわち、仮係止部16は、装着部13と両側壁12との間に2つ、装着部13を軸に軸対象に設けれられている。仮係止部16の幅は特に限定されない。仮係止部16の円弧状の長さは、特に限定されないが、その円弧角度が90°より小さい寸法にすることが好ましい。
【0022】
第2壁部11の仮係止部16の円弧方向前方(固定部材の回動方向前方)には、本係止部17が設けられている。
本係止部17は、どのように形成してもよいが、仮係止部16と同一円周上に沿って円弧状の孔に形成することが好ましい。本係止部17の幅は仮係止部16とほぼ同じに形成することが好ましい。本係止部17の円弧状の長さは、特に限定されないが、後述する押圧部の先端部が係合したとき、押圧部が回動方向後方へに移動し得ない寸法に形成するようにする。本係止部17の位置は、好ましくは、仮係止部16の回動方向後方側端部から円弧角度が90°前方位置であることが好ましい。
【0023】
また、第2壁部11、例えば、装着部13と仮係止部16の回動方向前方側端部との間には、その表面に対して直交する方向に沿って延在する回動防止突部18がそれぞれ設けられている。回動防止突部18は、後述する固定部材6の操作部31が接して操作部31(固定部材6)の回動範囲を規制するものである。回動防止突部18は、どのように形成してもよく、例えば、先端が半球状に形成されている円柱状に形成してもよい。回動防止突部18の位置は、固定部材6の係合突部33が本係止部17に係止されたとき、操作部31(固定部材6)の回動方向前方への回動を阻止し得る箇所である。
【0024】
固定部材6は、装着部13に装着された(設けられた)状態で操作部31を例えば時計回り(右回り)に回動させると、取付部材本体5内にFFC2が存在した場合には、そのFFC2を第1壁部10の内壁10aに押圧して取付部材本体5をFFC2に固定するものである。
固定部材6は、回動により取付部材本体5をFFC2に固定することができるならばどのように構成してもよい。
固定部材6、例えば、図1乃至図6、図8に示すように、装着時、取付部材本体を貫通する軸部30と、その軸部30の取付部材本体外に位置される一方の端部に取り付けられた操作部31と、軸部30の他方の端部に取り付けられ、取付部材本体5内のFFC2を第1壁部10の内壁10aに押圧する押圧板32とからなる。
【0025】
軸部30は、円柱状に形成されている。軸部30の径は、装着部13の径(スリットの幅)と同じか若干小さい寸法であって、固定部材6によって取付部材本体5をFFC2に固定する及び固定したときに、変形することがない寸法に形成されている。
【0026】
操作部31は、軸部30の一方の端部に一体的(個別でもよいが好ましくは一体的)に取り付けられている。操作部31は、軸部をその軸を中心に回動させるもので、例えば、その軸に対して直交する方向に沿って延在するハンドルである。
操作部31は、直線細長状のものや円形状のもの等どのような形状のものでもよいが、好ましくは、直線細長状のものがよい。
操作部31は、例えば、断面矩形の棒状に形成され、このほぼ中央部が、軸部30の一方の端部にその軸に対して直交する方向に沿って延在するように一体的に取り付けられている。
【0027】
操作部31の長さは、操作部31を指で掴んで操作することができるならば特に限定されず、例えば、取付部材本体5の幅のほぼ1/2の寸法に形成されている。操作部31の厚さは、固定部材6によって取付部材本体5をFFC2に固定する及び固定したときに、変形することがない寸法に形成されている。操作部31の幅は、固定部材6によって取付部材本体5をFFC2に固定する及び固定したときに、変形することがない寸法に形成され、さらに好ましくはスリットの幅より大きな寸法に形成されていることがよい。
操作部31の両端部は、曲面状に形成するようにしてもよい。
【0028】
押圧板32は、取付部材本体5内のFFC2を第1壁部10の内壁10aに押圧することができるならばどのようなものでもよく、例えば、円盤状に形成されている。
押圧板32の一方の表面の中央部(軸)に、軸部30の他方の端部が同軸上に一体的に取り付けられている。
押圧板32の径は、特に限定されないが、例えば、仮係止部16の外側のRと同じ又は若干小さな寸法に形成されている。
押圧板32の厚さは、固定部材6によって取付部材本体5をFFC2に固定する及び固定したときに、変形することがない寸法にそれぞれ形成されている。
【0029】
押圧板32の一方の表面の周縁部には、その周方向に沿って延在する押圧部である円弧状の係合突部33が1つ又は2つ以上、図示例では2つ一体的に形成されている。
係合突部33は、仮係止部16に嵌合し得る形状であって、回動方向後方側が押圧板32の一方の表面に対して直交する方向に沿って延在する垂直面34及びその垂直面34の頂部から押圧板32の一方の表面側に漸次傾斜して傾斜先端部が押圧板の一方の表面に達している傾斜面35を有するその周方向の断面が直角三角形状の突部として形成されている。その係合突部33の垂直面34の頂部が本係止部17に係合して係止されるものである。
【0030】
係合突部33の高さ(垂直面34の高さ)は、図3及び図4に示すように、係合突部33が仮係止部16に係合された仮係止状態では取付部材本体5がFFC2に対してその長手方向に対する移動が許容されると共に、図5及び図6に示すように、係止状態では取付部材本体5内のFFC2を他方の表面によって第1壁部10の内壁10aに押圧して取付部材本体5がFFC2に固定され得る寸法に形成されている。
すなわち、係合突部33の高さ(垂直面34の高さ)は、係合突部33が仮係止部16に完全に嵌合された状態(押圧板32の一方の表面が第2壁部11の内壁に接した状態)では、図3及び図4に示すように、押圧板32の他方の表面と第1壁部10の内壁10aとの間の間隔が取付部材本体5内のFFC2の厚さより長い寸法に形成されている。また、係合突部33の高さ(垂直面34の高さ)は、係止状態において、図5及び図6に示すように、押圧板32の他方の表面と第1壁部10の内壁10aとの間の間隔が取付部材本体5内のFFC2の厚さより短い寸法であって、フラットケーブル用取付部材1がFFC2に固定され得る寸法にも形成されている。
【0031】
2つの係合突部33は、図1乃至図6に示すように、操作部31の長手方向と平行な押圧板32の直径に対して対象の位置に設けられており、係合突部33が仮係止部16に嵌合され又は嵌合され得る状態(仮係止状態)においては、操作部31の長手方向(向き)が取付部材本体5の長さ方向(スリットの延在方向)と平行になるようになっている。また、係合突部33が本係止部17に係止された状態(本係止状態)では、操作部31の長手方向(向き)が仮係合状態とは90°向きが異なる取付部材本体5の幅方向と平行になるようになっている。このとき(係合突部33が本係止部17に係止されたとき)、操作部31が回動防止突部18に当接して、操作部31(固定部材6)の回動方向前方への回動が阻止されるように軸部30の長さを設定することが好ましい。
【0032】
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、固定部材6をスリット14を介して装着部13に装着する。この装着は、図3及び図4に示すように、操作部31を取付部材本体5外に位置させると共に、押圧板32を取付部材本体5内に位置させ、かつ、押圧板32の係合突部33が仮係止部16に嵌合した、又は嵌合し得る(係合突部33の一部が嵌合した)状態になるようにする。つまり、固定部材6は、操作部31が取付部材本体5の長さ方向(スリットの延在方向)と平行になるように装着部13に装着する。
【0033】
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押圧板32と第1壁部10の内壁10aとの間に挿入して貫通させる。この挿入は、FFC2の表面と第1壁部10の内壁10a及び第2壁部11の内壁とが対向するように行われる。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、押圧板32の他方の表面と第1壁部10の内壁10aとの間の間隔は取付部材本体5内の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。
【0034】
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。
【0035】
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。
【0036】
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1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。
【0037】
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、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。
【0038】
固定後、操作部31を時計回りに回動させる。すると、係合突部33の傾斜面35が仮係止部16の回動方向前方の壁部に当接しながら操作部31及び固定部材6が回動して、固定部材6(軸部30)が取付部材本体5内へと移動する(操作部31から押圧板32方向に移動する)。つまり、操作部31が回動しながら第2壁部11の外表面に近づく。
【0039】
そして、係合突部33の垂直面34の頂部が仮係止部16から離脱して、図2、図5及び図6に示すように、本係止部17に係合する。このとき、本係止部17に係合した係合突部33の回動方向後方側は垂直面34として形成されているため、係合突部33の垂直面34の上方が本係止部17を形成する壁部に面接触し、操作部31(係合突部33)は回動方向後方側に移動することがない。また、操作部31は、回動防止突部18に当接して、操作部31(固定部材6)の回動方向前方への回動が阻止される。よって、係合突部33(固定部材6)は本係止部17に係止された本係止状態になる。
【0040】
このように、係合突部33が仮係止部16から本係止部17に移行(移動)するとき、係合突部33の回動方向前方が傾斜面に形成されているため、係合突部33が仮係止部16から抜け出し易く、容易に操作部31を回動させることができる。よって、固定部材6を容易に仮係止状態から本係止状態に移行させることができる。
【0041】
また、固定部材6(軸部30)が取付部材本体5内へと移動すると、押圧板32もその移動に伴って第1壁部10の内壁10aに向って移動する。押圧板32の他方の表面はFFC2の表面に接し、さらに軸部30及び押圧板32の移動に伴って、押圧板32がFFC2を第1壁部10の内壁10aに押圧する。固定部材6が本係止状態であると、押圧板32の他方の表面と第1壁部10の内壁10aとの間の間隔が取付部材本体5内のFFC2の厚さより短く形成されているので、FFC2は、押圧板32と第1壁部10の内壁10a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。
【0042】
また、先にフラットケーブル用取付部材1をクリップ部20を介して車体3に固定したが、車体3内でフラットケーブル用取付部材1のクリップ部20の車体3の係止孔4への位置調節を行ってから固定部材6を回動させてフラットケーブル用取付部材1をFFC2に固定し、その後、フラットケーブル用取付部材1をクリップ部20を介して車体3に固定するようにしてもよい。
【0043】
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。
【0044】
また、取付部材本体5が矩形筒体状に形成され、係止部材7(クリップ部20)が第1壁部10に設けられていると共に、固定部材6が第1壁部10と対向する第2壁部11に設けられていることで、係止部材7により取付部材本体5を車体3に係止させて固定した後に、取付部材本体5をFFC2に固定することができる。このため、取付部材本体5を車体3に固定した後でも取付部材本体5をFFC2に固定する位置の調節を行える。また、取付部材本体5を車体3に固定するとき、取付部材本体5とFFC2とは固定状態の関係ではないので、取付部材本体5の車体3への固定作業を行い安い。よって、FFC2の車体3への組付け作業性が一層向上することになる。
【0045】
また、固定部材6が軸部30と操作部31と押圧板32とからなることにより、固定部材6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1壁部10の内壁10a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。
【0046】
また、操作部31を約90°回動させて固定部材6を仮係止状態から本係止状態に移行(移動)させることで、操作部31が例えば直線細長状に形成されていると、仮係止状態と本係止状態とでは操作部31の向きが90°異なる。このため、フラットケーブル用取付部材1がフラットケーブルに固定されているか否かを容易に特に目視では極めて容易に把握することができる。また、操作部31が円形のハンドルである場合には、ハンドルの一部に矢印等の目印をつけておくようにしてもよい。
【0047】

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. 9, 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]
Further, 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 obstacle 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 table 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 if a flat cable attachment member is attached to a predetermined portion of the FFC arranged on the arrangement 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.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, the flat cable mounting member of the present invention is attached to the flat cable, Body A flat cable mounting member fixed to
The flat cable is attached to the flat cable so as to surround the flat cable and allow the flat cable to move in the longitudinal direction. Rectangular tube A mounting member body; A locking member provided on one wall portion of the mounting member body and locked to the vehicle body, and a rearmost portion of a slit formed on the other wall portion facing the one wall portion of the mounting member body Attached to the mounting part The operation unit located outside the attachment member main body is rotated to connect the flat cable in the attachment member main body to the attachment member main body. Of the one wall A fixing member that presses against the inner wall and fixes the mounting member body to the flat cable,
The fixing member has a shaft portion penetrating the mounting portion, the operation portion attached to an end portion of the shaft portion located outside the attachment member main body, and one surface at the other end portion of the shaft portion. And a pressing plate that presses the flat cable in the mounting member main body against the inner wall of the one wall portion of the mounting member main body on the other surface, and the mounting member main body is formed on the one surface of the pressing plate. Engaging the temporary locking portion provided on the other wall portion of the mounting member to allow the mounting member main body to move in the longitudinal direction of the flat cable and to engage with the temporary locking portion by the rotation. And a pressing portion which is released and locked to the main locking portion provided on the other wall portion of the mounting member main body. 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 Body When wiring to the flat cable mounting member Body Even 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. When the operation portion is rotated, the flat cable in the attachment member main body is pressed against the inner wall of the attachment member main body by the fixing member, and the attachment member main body is fixed to the flat cable.
Therefore, a flat cable mounting member that improves the workability of assembling a flat cable such as an FFC to a fixed body such as a vehicle body can be obtained.
Also, Since the locking member and the fixing member are separately provided on opposing wall portions of the mounting member main body, the mounting member main body is locked to the fixed body by the locking member, and then the mounting member main body is fixed to the flat cable. Can be fixed to. For this reason, since the position which fixes an attachment member main body to a flat cable can be adjusted even after fixing an attachment member main body to a fixed body, the assembly work property to the fixed body of a flat cable further improves.
Also, It is possible to fix the mounting member body to the flat cable by pressing the flat cable in the mounting member body against the inner wall of the mounting member body with a simple structure without using other members such as a spring.
The shaft portion is formed in a columnar shape, the operation portion is formed in a linear elongated shape, and the shaft portion is arranged so that the longitudinal direction and the axial direction of the shaft portion are orthogonal to the substantially central portion in the longitudinal direction of the operation portion. One end of the pressure plate is attached, the pressing plate is formed in a disc shape, and in the central portion of the pressing plate, The pressing plate The other end portion of the shaft portion is attached so that the axial direction of the shaft portion and the axial direction of the shaft portion are substantially coaxial, and the pressing portion is disposed on the surface of the pressing plate on which the shaft portion is attached. It is preferable that it is an arc-shaped engagement protrusion that extends along the direction.
Thereby, a fixing member can be formed in a simple structure.
As the forward direction of the pressing portion moves forward, the pressing plate gradually moves forward. Said one It is formed as an inclined surface inclined to the surface side, and the inclined tip of this inclined surface is Said one It is preferable to reach the surface.
As a result, when the operating portion is rotated and the pressing portion comes out of the temporary locking portion, the rotation direction front of the pressing portion, which is a portion in contact with the wall portion forming the temporary locking portion, is formed as an inclined surface. Therefore, the pressing portion can easily come out of the temporary locking portion, and the operation portion can be easily rotated. Therefore, the fixing member can be easily shifted from the temporarily locked state to the fully locked state.
The main locking portion of the mounting member main body is configured to lock the pressing portion when the operation portion is rotated about 90 °. The other wall Is preferably provided.
As a result, if the operation portion is formed in, for example, a straight elongated shape, the orientation of the operation portion is 90 ° different between the temporarily locked state and the final locked state, so whether or not the mounting member body is fixed to the flat cable. Can be easily grasped.

The portion 33 is fitted to the temporary locking portion 16 or can be fitted (a part of the engaging projection 33 is fitted). That is, the fixing member 6 is attached to the attachment portion 13 so that the operation portion 31 is parallel to the length direction of the attachment member main body 5 (slit extending direction).
[0033]
One end portion of the FFC 2 is inserted between the pressing plate 32 and the inner wall 10a of the first wall portion 10 through one opening of the mounting member body 5 so that the mounting member body 5 surrounds the outer periphery of the FFC 2. Let This insertion is performed so that the surface of the FFC 2 faces the inner wall 10a of the first wall 10 and the inner wall of the second wall 11. 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 other surface of the pressing plate 32 and the inner wall 10a of the first wall portion 10 is formed to be longer than the thickness of the FFC 2 in the mounting member body 5, so that the flat cable mounting member 1 is used. Is allowed to move in the longitudinal direction of the FFC 2.
[0034]
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.
[0035]
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.

Moves into the mounting member main body 5 (moves from the operation unit 31 toward the pressing plate 32). That is, the operation part 31 approaches the outer surface of the second wall part 11 while rotating.
[0039]
Then, the top of the vertical surface 34 of the engaging protrusion 33 is detached from the temporary locking portion 16 and is engaged with the main locking portion 17 as shown in FIGS. 2, 5, and 6. At this time, since the rear side in the rotation direction of the engaging protrusion 33 engaged with the main locking portion 17 is formed as a vertical surface 34, the upper side of the vertical surface 34 of the engaging protrusion 33 is the main locking portion. The operation unit 31 (engagement projection 33) does not move rearward in the rotational direction. Further, the operation unit 31 is in contact with the rotation preventing protrusion 18 and is prevented from rotating forward in the rotation direction of the operation unit 31 (fixing member 6). Therefore, the engagement protrusion 33 (fixing member 6) is in the final locking state locked to the main locking portion 17.
[0040]
As described above, when the engaging protrusion 33 shifts (moves) from the temporary locking portion 16 to the main locking portion 17, the front of the engaging protrusion 33 in the rotational direction is formed on the inclined surface. The mating protrusion 33 can easily come out of the temporary locking portion 16, and the operation portion 31 can be easily rotated. Therefore, the fixing member 6 can be easily shifted from the temporarily locked state to the fully locked state.
[0041]
When the fixing member 6 (shaft portion 30) moves into the attachment member main body 5, the pressing plate 32 also moves toward the inner wall 10a of the first wall portion 10 along with the movement. The other surface of the pressing plate 32 is in contact with the surface of the FFC 2, and the pressing plate 32 presses the FFC 2 against the inner wall 10 a of the first wall portion 10 as the shaft portion 30 and the pressing plate 32 move. Since the interval between the other surface of the pressing plate 32 and the inner wall 10a of the first wall portion 10 is formed shorter than the thickness of the FFC 2 in the mounting member main body 5 when the fixing member 6 is in the final locking state. The FFC 2 is sandwiched between the pressing plate 32 and the inner wall 10 a of the first wall portion 10, and the flat cable mounting member 1 is fixed to the FFC 2.
[0042]

Then, the fixing member 6 may be rotated to fix the flat cable mounting member 1 to the FFC 2, and then the flat cable mounting member 1 may be fixed to the vehicle body 3 via the clip portion 20.
[0043]
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. .
[0044]
The attachment member body 5 is formed in a rectangular cylindrical shape, the locking member 7 (clip portion 20) is provided on the first wall portion 10, and the fixing member 6 is opposed to the first wall portion 10. Since the two wall portions 11 are provided, the mounting member main body 5 can be fixed to the FFC 2 after the mounting member main body 5 is locked to the vehicle body 3 by the locking member 7 and fixed. For this reason, even after fixing the attachment member main body 5 to the vehicle body 3, the position where the attachment member main body 5 is fixed to the FFC 2 can be adjusted. Further, when fixing the attachment member main body 5 to the vehicle body 3, the attachment member main body 5 and the FFC 2 are not in a fixed state, so that the fixing operation of the attachment member main body 5 to the vehicle body 3 is performed and is inexpensive. Therefore, the workability of assembling the FFC 2 to the vehicle body 3 is further improved.
[0045]
Further, since the fixing member 6 includes the shaft portion 30, the operation portion 31, and the pressing plate 32, the fixing member 6 can be formed in a simple structure. Further, the FFC 2 in the attachment member main body 5 can be pressed against the inner wall 10a of the first wall portion 10 by a simple structure without using other members such as a spring, so that the attachment member main body 5 can be fixed to the FFC 2.
[0046]
Further, when the operation unit 31 is formed in, for example, a linear elongated shape by rotating (moving) the fixing member 6 from the temporarily locked state to the fully locked state by rotating the operating unit 31 by about 90 °. The direction of the operation part 31 differs by 90 ° between the temporarily locked state and the fully locked state. For this reason, it can be easily grasped | ascertained easily especially visually whether the attachment member 1 for flat cables is being fixed to the flat cable. When the operation unit 31 is a circular handle, a mark such as an arrow may be attached to a part of the handle.
[0047]
