【発明の属する技術分野】
本発明は、車体とバックドアのガラスハッチとの間を架けわたしたワイヤハーネスを被覆保護する筒状のワイヤハーネスプロテクタをガラスハッチ側に係止するクランプ固定構造に関する。
【0002】
【従来の技術】
図2に示すように、車両のバックドアBのウィンド開口B1を開閉するガラスハッチGは、上縁の左右位置がヒンジ部材Hを介して車体のルーフR後端に上下回動可能に支持されている。ガラスハッチGには、その内面の上端位置にハイマウントストップランプ(以下、ランプという)G1を備え、かつ、内面の下端位置にワイパG2を駆動するワイパユニットG3を備えている。そして、ルーフR後端とガラスハッチGの上端との間に筒状のワイヤハーネスプロテクタ1を架けわたし、これに挿通してランプG1およびワイパユニットG3へ電力を供給するワイヤハーネスをルーフR後端からランプG1へ配線している。また、ワイパユニットG3へ接続するワイヤハーネスW1は、チューブ等で被覆されてガラスハッチGの周縁に沿ってランプG1からワイパユニットG3へ配線している。
【0003】
図3および図4はワイヤハーネスプロテクタの代表例を示すもので、ワイヤハーネスプロテクタ1は、ルーフR後端に取付けた蛇腹状のグロメット2と、ほぼ直角に屈曲したL字形のプロテクタ部材3と、グロメット4と、プロテクタ部材5、およびガラスハッチGの上端を貫通せしめたグロメット6を一連に連結したもので、プロテクタ部材3が、ヒンジ部材Hのヒンジアームに固定されてルーフR後端とガラスハッチGとの連結部を被覆しガラスハッチGと一体に回動するカバー部材G4の内面にクランプ7Aにより固定されている。図中、Wはワイヤハーネスである。
【0004】
図5および図6に示すように、従来、一般に用いられるクランプ7Aは合成樹脂製で、平板状の基板部71と、基板部71とで断面コ字形をなす弾性係止片73を備え、係止片73には係止爪74が形成してある。クランプ7Aは、その基板部71と係止片73との間の間隙内に、プロテクタ部材3の屈曲部の内側外面に突設した平板状のクランプ取付け座部31を嵌入し、基板部71と係止片73とで取付け座部31を挟み付けるとともに、係止片73の係止爪74を取付け座部31の係止孔32に係止してプロテクタ部材3に固定している。取付け座部31は左右の両端に沿って突出した壁状のフランジ33を設けて補強している。
【0005】
また、クランプ7Aは基板部71の裏面側に吸盤状のリップ部76と、係止脚77を備えており、係止脚77をカバー部材G4のクランプ孔に嵌入してカバー部材G4に固定している。
【0006】
【発明が解決しようとする課題】
ところで近時、車両へのルーフスポイラの設置が流行となっており、一旦設置されたカバー部材G4をルーフスポイラ付きのカバー部材に組替える場合がある。この場合、ワイヤハーネスプロテクタ1は、そのプロテクタ部材3をクランプ7Aからはずしてカバー部材G4から取りはずし、カバー部材を組替え、元のカバー部材G4からはずしたクランプ7Aを用いてワイヤハーネスプロテクタ1を新しいルーフスポイラ付きのカバー部材の内面に固定している。
【0007】
ところが、クランプ7Aからプロテクタ部材3をはずす際、クランプ7Aの係止片73を外側に撓ませ、これと基板部71との間の間隙を開いて係止爪74と取付け座部31の係止孔32との係合を解除することがなされるが、撓み変形する係止片73と一体に取付け座部31が移動してしまう。そこで、係止爪74を係止孔32から抜き取るために係止片73を更に撓ませると係止片73が破損するおそれがある。また、破損に至らないまでも係止片73に永久変形が生じて係止片73の弾性力が失われ、これにプロテクタ部材3を取付けても、取付け座部31を挟み付けるホールド力が低下してはずれやすい。
【0008】
そこで、本発明は、簡素な構造で、ワイヤハーネスプロテクタとクランプとの結合力が強固で、かつ、着脱作業が容易なワイヤハーネスプロテクタのクランプ固定構造を実現することを課題としてなされたものである。
【0009】
【課題を解決するための手段】
本発明は、車体と、バックドアのウィンド開口を開閉するガラスハッチとの間を架けわたすワイヤハーネスを被覆して保護する筒状のワイヤハーネスプロテクタをガラスハッチ側に係止するクランプ固定構造であって、ワイヤハーネスプロテクタには、平板状のクランプ取付け座部を突設し、クランプは基板部と、基板部とで断面コ字形をなし先端に係止爪を有する弾性係止片と、基板部の裏面から突出する係止脚を備え、上記クランプ取付け座部をクランプの上記基板部と上記係止片の間の間隙に嵌入して、上記係止爪を上記取付け座部に設けた係止孔に係合せしめるとともに、上記係止脚をガラスハッチ側のクランプ孔に係止せしめるようになしたワイヤハーネスプロテクタのクランプ固定構造において、上記クランプ取付け座部にはその側縁に沿い該側縁よりも内側寄りの位置から突出する補強フランジを設け、上記基板部の側縁にはこれに沿って上記間隙内に向かって開口する断面コ字形で、上記弾性係止片とはスリットにより分離された嵌合溝を形成し、上記クランプ取付け座部の上記間隙への嵌入時に、同時に上記クランプ取付け座部の側縁および補強フランジがそれぞれ上記クランプの嵌合溝およびスリットに嵌入するようにした
【0010】
必要に応じてワイヤハーネスプロテクタをクランプからはずす場合、クランプの基板部の側縁に設けた嵌合溝がワイヤハーネスプロテクタの取付け座部の側縁を嵌合保持しているので、係止片を撓ませても取付け座部は移動しない。よって、取付け座部に上記嵌合溝に沿う抜き方向の力を与えつつ係止片を撓ませると、係止爪が係止孔から抜けた瞬間に取付け座部が抜き出される。従って、取付け座部を抜き出すための係止片の撓みを最小限とすることができ、クランプには破損や永久変形が発生しない。
【0011】
【発明の実施の形態】
図2に示すように、ガラスハッチGは車体のルーフR後端にヒンジ部材Hを介してバックドアBと同軸に上下方向回動自在に取付けてある。ヒンジ部材Hには同軸回動する上下一対のヒンジアームを備え、下側のヒンジアームにバックドアBを取付けるとともに、上側のヒンジアームにガラスハッチGが取付けてあり、ガラスハッチGはバックドアBとは独立に回動してバックドアBのウィンド開口B1を開閉する。また、ルーフR後端とバックドアBおよびガラスハッチGの連結部はカバー部材G4で被覆してある。カバー部材G4は上記上側のヒンジアームにボルト締め固定してあり、ガラスハッチGと一体に回動する。
【0012】
ガラスハッチGには、その内面の上端位置にランプG1が付設してあり、内面の下端位置にワイパG2を駆動するワイパユニットG3が付設してある。また、ルーフR後端とガラスハッチGとの連結部には、カバー部材G4の内面に沿ってルーフR後端からガラスハッチGの上端にかけて筒状のワイヤハーネスプロテクタ1が架設してあり、これにランプG1およびワイパユニットG3に接続するワイヤハーネスW(図4)を挿通して、ワイヤハーネスWをルーフR後端からランプG1へ配線している。図のW1はランプG1からワイパユニットG3へ接続するワイヤハーネスで、チューブ等で被覆されてガラスハッチGの周縁に沿って配線してある。
【0013】
図3および図4に示すように、ワイヤハーネスプロテクタ1は、軟質材よりなる第1、第2および第3のグロメット2,4,6を硬質材よりなる第1および第2のプロテクタ部材3,5を介して一連に連結したものである。第1のグロメット2は円筒状で一端に設けた取付け部21がルーフR後端の貫通孔R1に係合固定してあり、他端に第1のプロテクタ部材3が連結してある。第1のグロメット2はその中間部を蛇腹部22として捩れ変形可能としてある。第1のプロテクタ部材3はL字形で、第1のグロメット2と連結する一方の開口側35は円筒状で、他方の開口側36は偏平筒状としてあり、他方の開口に、同じく偏平筒状の第2のグロメット4の一端が連結してある。第2のグロメット4の他端には偏平筒状の第2のプロテクタ部材5の一端が連結してあり、第2のプロテクタ部材5の他端には偏平筒状の第3のグロメット6が連結してある。第3のグロメット6の後端には一対の筒状の脚部61が延設され、それぞれガラスハッチGの上端を貫通せしめてランプG1のケース内に挿入してある。そして、ワイヤハーネスプロテクタ1は、第1のプロテクタ部材3をクランプ7によりカバー部材G4の内面前端に固定するとともに、第2のプロテクタ部材5をホルダー部材8によりガラスハッチGの上端外面に固定してルーフR後端とガラスハッチGの上端間を架けわたしてある。ガラスハッチGの開閉回動に伴って第1のグロメット2の蛇腹部22が捩じれ変形する。
【0014】
図1に示すように、第1のプロテクタ部材3には、直角状の屈曲部の内側にクランプ取付け座部31が一体に成形してある。取付け座部31は屈曲部の内側に突出する四角形平板状で、取付け座部31には、第2のグロメット4を連結する筒部36に接する側縁に沿って突出する壁状の補強フランジ33aが設けてあり、上記側縁と対向する反対側の側縁34側にも若干内側寄りの位置に補強フランジ33aと平行な壁状の補強フランジ33bが設けてあり、側縁34は補強フランジ33bの外側に突出している。また、取付け座部31には、両補強フランジ33a,33b間の中間位置に角形の係止孔32が形成してある。
【0015】
一方、クランプ7は合成樹脂製で、その本体は、四角形の基板部71と、基板部71の相隣れる二つの側縁から起立する側壁72a,72bと、側壁72a,72bの上縁を相隣れる二つの側縁とする基板部71とほぼ同形の上板73からなる。
【0016】
上板73と基板部71とは互いに平行で、間隙をおいて対向している。上板73は、側壁72a側の側縁に近接してこれに沿う方向に形成したスリット731により、側壁72a側の部分73aと他の部分73bに分離している。他の部分73bは、その根元を中心に撓み変形可能な弾性係止片を形成し、係止片73bと側壁72bおよび基板部71とで断面コ字形をなしている。係止片73bの先端縁には起立するフランジ732が形成してあり、また、係止片73bの中央先端寄りの位置には基板部71方向に突出する係止爪74が形成してある。係止爪74は断面ほぼ直角三角形で、係止片73bの先端側から根元方向へと緩い傾斜角で立ち上がる傾斜面を備えている。
【0017】
また、上板73の上記部分73aは、側壁72aおよび基板部71の端部とで側壁72aに沿い、スリット731側に開口する断面コ字形の嵌合溝75を形成している。弾性係止片73bの先端の開口と、嵌合溝75の係止片73b方向に向く開口とは互いに直角方向となっている。
【0018】
基板部71の裏面には、基板部71と一体に吸盤状のリップ部76が形成してあり、リップ部76の中心から係止脚77が突出している。係止脚77にはその両側に先端からリップ部76方向に向かって延びる一対の弾性爪片771が設けてある。
【0019】
クランプ7は、その本体の弾性係止片73bの先端側を取付け座部31と対向せしめ、スリット731と補強フランジ33bを位置合わせするとともに、両補強フランジ33a,33b間に弾性係止片73bを位置せしめて、クランプ7を第1のプロテクタ部材3の筒部36に沿って押し込む。これにより、取付け座部31の一般部は係止片73bを押し上げつつ基板部71と係止片73bとの間の間隙内に圧入され、取付け座部31の側縁34はクランプ7の嵌合溝75に嵌入され、取付け座部31の補強フランジ33bがクランプ7のスリット731に嵌入され、係止爪74が取付け座部31の係止孔32に嵌入係止することによりクランプ7は第1のプロテクタ部材3に固定される。
【0020】
そして、クランプ7は、係止脚77をカバー部材G4の内板に設けたクランプ孔に嵌入して、リップ部76をカバー部材G4のクランプ孔まわりのパネル面に圧接するとともに、係止脚77の弾性爪片771をクランプ孔に係合せしめることにより、第1のプロテクタ部材3をカバー部材G4に固定する。
【0021】
カバー部材G4の組替え等のためにクランプ7からプロテクタ部材3をはずす場合、弾性係止片73bのフランジ732にマイナスドライバ等の工具の先端を引っ掛けて係止片73bを外側方向に撓ませつつ基板部71と係止片73b間の間隙を開いて係止爪74と取付け座部31の係止孔32との係合を解除する。このとき、取付け座部31の側縁34がクランプ7の嵌合溝75に嵌入保持されているので、取付け座部31は基板部71側に保持される。従って、取付け座部31に嵌合溝75に沿い軽い抜け荷重を与えつつ係止片73bを撓ませれば、係止爪74が係止孔32から抜け出す時点で取付け座部31を抜き出すことができる。従って、取付け座部31をクランプ7から抜きとるための係止片73bの撓みは最小限とすることができ、係止片73bの破損や、変形を防止することができるので、クランプ7は再度のプロテクタ部材3への取付けに有効に利用することができる。
【0022】
また、クランプ7とプロテクタ部材3との結合部において、プロテクタ部材3の取付け座部31は係止片73bに係止されるともに、取付け座部31の側縁34は基板部71の嵌合溝75に係止されているので、取付け座部31とクランプ7との結合は安定かつ強固である。
【0023】
【発明の効果】
本発明のクランプ固定構造によれば、簡素な構造で、ワイヤハーネスプロテクタとクランプとの結合力が安定かつ強固である。かつ、必要に応じてワイヤハーネスプロテクタをクランプから無理なく容易に取りはずすことができる。従って、取りはずし時にクランプが破損したり永久変形したりすることがなく、クランプは再度、ワイヤハーネスプロテクタを取付けて有効に使用することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a clamp fixing structure for locking a tubular wire harness protector for covering and protecting a wire harness extending between a vehicle body and a glass hatch of a back door to a glass hatch side.
[0002]
[Prior art]
As shown in FIG. 2, a glass hatch G that opens and closes a window opening B1 of a back door B of a vehicle is supported at the left and right positions of an upper edge at a rear end of a roof R of a vehicle body via a hinge member H so as to be vertically rotatable. ing. The glass hatch G is provided with a high-mount stop lamp (hereinafter, referred to as a lamp) G1 at an upper end position on an inner surface thereof, and a wiper unit G3 for driving a wiper G2 at a lower end position on the inner surface. Then, a cylindrical wire harness protector 1 is provided between the rear end of the roof R and the upper end of the glass hatch G, and the wire harness inserted therethrough to supply power to the lamp G1 and the wiper unit G3 is connected to the rear end of the roof R. To the lamp G1. The wire harness W1 connected to the wiper unit G3 is covered with a tube or the like, and is wired from the lamp G1 to the wiper unit G3 along the periphery of the glass hatch G.
[0003]
3 and 4 show a typical example of a wire harness protector. A wire harness protector 1 includes a bellows-like grommet 2 attached to a rear end of a roof R, an L-shaped protector member 3 bent at a substantially right angle, and A grommet 4, a protector member 5, and a grommet 6 penetrating the upper end of the glass hatch G are connected in series. The protector member 3 is fixed to a hinge arm of a hinge member H, and the rear end of the roof R and the glass hatch are connected. It is fixed by a clamp 7A to the inner surface of a cover member G4 which covers a connection portion with G and rotates integrally with the glass hatch G. In the figure, W is a wire harness.
[0004]
As shown in FIGS. 5 and 6, a conventionally used clamp 7A is generally made of synthetic resin, and has a flat board portion 71 and an elastic locking piece 73 having a U-shaped cross section with the board portion 71. A locking claw 74 is formed on the stopper 73. The clamp 7 </ b> A fits the flat plate-shaped clamp mounting seat portion 31 protruding from the inner outer surface of the bent portion of the protector member 3 into the gap between the board portion 71 and the locking piece 73. The mounting piece 31 is sandwiched between the locking piece 73 and the locking claw 74 of the locking piece 73 is locked in the locking hole 32 of the mounting seat 31 and fixed to the protector member 3. The mounting seat 31 is reinforced by providing wall-shaped flanges 33 protruding along both left and right ends.
[0005]
Further, the clamp 7A has a suction cup-shaped lip 76 and a locking leg 77 on the back side of the substrate portion 71, and the locking leg 77 is fitted into a clamp hole of the cover member G4 and fixed to the cover member G4. ing.
[0006]
[Problems to be solved by the invention]
By the way, recently, installation of a roof spoiler in a vehicle has become popular, and the cover member G4 once installed may be replaced with a cover member with a roof spoiler. In this case, the wire harness protector 1 removes the protector member 3 from the clamp 7A, removes the protector member 3 from the cover member G4, rearranges the cover member, and uses the clamp 7A removed from the original cover member G4 to replace the wire harness protector 1 with a new roof. It is fixed to the inner surface of a cover member with a spoiler.
[0007]
However, when the protector member 3 is removed from the clamp 7A, the locking piece 73 of the clamp 7A is bent outward to open a gap between the locking piece 73 and the substrate 71, thereby locking the locking claw 74 and the mounting seat 31. The engagement with the hole 32 is released, but the mounting seat portion 31 is moved integrally with the locking piece 73 that bends and deforms. Therefore, if the locking piece 73 is further bent to remove the locking claw 74 from the locking hole 32, the locking piece 73 may be damaged. Further, even if the locking piece 73 is not damaged, the locking piece 73 is permanently deformed and the elastic force of the locking piece 73 is lost. Even if the protector member 3 is mounted on the locking piece 73, the holding force for sandwiching the mounting seat 31 is reduced. It is easy to come off.
[0008]
Therefore, an object of the present invention is to provide a clamp fixing structure of a wire harness protector which has a simple structure, has a strong coupling force between a wire harness protector and a clamp, and is easy to attach and detach. .
[0009]
[Means for Solving the Problems]
The present invention is a clamp fixing structure for locking a cylindrical wire harness protector for covering and protecting a wire harness extending between a vehicle body and a glass hatch that opens and closes a window opening of a back door on the glass hatch side. The wire harness protector has a plate-shaped clamp mounting seat protruding therefrom, and the clamp has an elastic locking piece having a U-shaped cross section formed by a substrate portion and a substrate portion and having a locking claw at a tip thereof; A locking leg protruding from the back surface of the clamp, wherein the clamp mounting seat is fitted into a gap between the substrate portion of the clamp and the locking piece, and the locking claw is provided on the mounting seat. together occupy engage the hole, Waso the locking Tomeashi in clamping structure of the wire harness protector without as allowed to engage with the clamp holes of the glass hatch side, to the clamp mount seat A reinforcing flange is provided along the side edge and protrudes from a position closer to the inside than the side edge, and the side edge of the substrate portion has a U-shaped cross-section opening toward the inside of the gap along the side edge. A fitting groove separated from the piece by a slit is formed, and when the clamp mounting seat is fitted into the gap, the side edge and the reinforcing flange of the clamp mounting seat are simultaneously fitted to the fitting groove and the slit of the clamp, respectively. To fit in .
[0010]
When removing the wire harness protector from the clamp if necessary, the fitting groove provided on the side edge of the board part of the clamp fits and holds the side edge of the mounting seat of the wire harness protector. Even if it is bent, the mounting seat does not move. Therefore, when the locking piece is bent while applying a force in the removing direction along the fitting groove to the mounting seat, the mounting seat is pulled out at the moment when the locking claw comes out of the locking hole. Therefore, the bending of the locking piece for extracting the mounting seat can be minimized, and the clamp is not damaged or permanently deformed.

The other portion 73b forms an elastic locking piece that can be bent and deformed around its root, and the locking piece 73b, the side wall 72b, and the substrate 71 have a U-shaped cross section. An upstanding flange 732 is formed on the leading edge of the locking piece 73b, and a locking claw 74 protruding in the direction of the substrate 71 is formed at a position near the center of the locking piece 73b. The locking claw 74 has a substantially right-angled triangular cross section, and has an inclined surface that rises from the tip end side of the locking piece 73b toward the root at a gentle inclination angle.
[0017]
The portion 73a of the upper plate 73 is formed along the side wall 72a with the side wall 72a and the end of the substrate portion 71 to form a fitting groove 75 having a U-shaped cross section that opens toward the slit 731. The opening at the tip of the elastic locking piece 73b and the opening of the fitting groove 75 facing the locking piece 73b are perpendicular to each other.
[0018]
A sucker-like lip 76 is formed integrally with the substrate 71 on the back surface of the substrate 71, and a locking leg 77 projects from the center of the lip 76. The locking leg 77 is provided with a pair of elastic claw pieces 771 extending from the tip toward the lip portion 76 on both sides thereof.
[0019]
The clamp 7 has the distal end side of the elastic locking piece 73b of the main body facing the mounting seat 31, aligns the slit 731 with the reinforcing flange 33b, and places the elastic locking piece 73b between the reinforcing flanges 33a and 33b. After being positioned, the clamp 7 is pushed along the cylindrical portion 36 of the first protector member 3. As a result, the general portion of the mounting seat portion 31 is pressed into the gap between the board portion 71 and the locking piece 73b while pushing up the locking piece 73b, and the side edge 34 of the mounting seat portion 31 is fitted with the clamp 7. The clamp 7 is fitted into the groove 75, the reinforcing flange 33 b of the mounting seat 31 is fitted into the slit 731 of the clamp 7, and the locking claw 74 is fitted and locked in the locking hole 32 of the mounting seat 31, so that the clamp 7 is in the first position. Is fixed to the protector member 3.
[0020]
Then, the clamp 7 fits the locking leg 77 into a clamp hole provided in the inner plate of the cover member G4, presses the lip portion 76 against a panel surface around the clamp hole of the cover member G4, and sets the locking leg 77. The first protector member 3 is fixed to the cover member G4 by engaging the elastic claw pieces 771 with the clamp holes.
[0021]
When the protector member 3 is detached from the clamp 7 for the rearrangement of the cover member G4 or the like, the tip of a tool such as a flathead screwdriver is hooked on the flange 732 of the elastic locking piece 73b so that the locking piece 73b is bent outward. The gap between the portion 71 and the locking piece 73b is opened to release the engagement between the locking claw 74 and the locking hole 32 of the mounting seat 31. At this time, since the side edge 34 of the mounting seat 31 is fitted and held in the fitting groove 75 of the clamp 7, the mounting seat 31 is held on the substrate 71 side. Therefore, if the locking piece 73b is bent while applying a light load to the mounting seat 31 along the fitting groove 75, the mounting seat 31 can be pulled out when the locking claw 74 comes out of the locking hole 32. it can. Therefore, the bending of the locking piece 73b for removing the mounting seat 31 from the clamp 7 can be minimized, and the damage and deformation of the locking piece 73b can be prevented. Can be effectively used for attachment to the protector member 3.
[0022]
At the joint between the clamp 7 and the protector member 3, the mounting seat 31 of the protector member 3 is locked by the locking piece 73b, and the side edge 34 of the mounting seat 31 is fitted into the fitting groove of the substrate 71. Since it is locked at 75, the connection between the mounting seat 31 and the clamp 7 is stable and strong.
[0023]
【The invention's effect】
According to the clamp fixing structure of the present invention, the coupling force between the wire harness protector and the clamp is stable and strong with a simple structure. In addition, the wire harness protector can be easily and easily removed from the clamp as needed. Therefore, the clamp does not break or is permanently deformed when it is removed, and the clamp can be effectively used again by attaching the wire harness protector again.
