Description

本発明は自動車等に配索されるワイヤハーネスの保護構造に関し、詳しくは、ワイヤハーネスを外装したコルゲートチューブをプロテクタと接続し、電線群をコルゲートチューブから引き出してプロテクタ内に挿通する際に、コルゲートチューブの先端にワイヤハーネスの電線群が干渉するのを防止し、電線群に損傷が発生しないようにするものである。   The present invention relates to a protective structure for a wire harness that is routed in an automobile or the like, and more specifically, when a corrugated tube with an outer sheath of a wire harness is connected to a protector and a wire group is pulled out of the corrugated tube and inserted into the protector. The wire group of the wire harness is prevented from interfering with the tip of the tube so that the wire group is not damaged.

自動車に配索するワイヤハーネスには、他の車載部品等の外部干渉を防止するために、所要箇所に、合成樹脂製で剛性を有すると共に、谷部と山部とが軸線方向に交互に設けられて屈曲性に富んだコルゲートチューブが外装されている。
前記ゴルゲートチューブは長尺に製造され、所要長さで切断して使用されており、切断端は剛性を有する樹脂端からなるため、鋭利なエッジを呈することとなる。
このゴルゲートチューブ内に電線群からなるワイヤハーネスを挿通させる場合、図５（Ａ）に示すように、電線群の外周にテープが密に巻きつけられて保護されているワイヤハーネス２の場合には、コルゲートチューブ１の切断端１ａからワイヤハーネス２が引き出される際に干渉しても、電線群をテープで保護されているため、前記エッジが電線に直接当たらず損傷の発生をある程度防止することができる。しかしながら、図５（Ｂ）に示すように、電線ｗにテープにより結束保護されていない場合には、振動等によりコルゲートチューブ１の切断端１ａに接触すると電線ｗに損傷が発生し、隣接する電線間でショートが生じる恐れがある。特に、ノンハロ電線の被覆は破れやすく、コルゲートチューブの切断端との干渉が問題となっている。 To prevent external interference from other in-vehicle components, etc., the wiring harness that is routed to the automobile is made of synthetic resin and has rigidity at the required locations, and valleys and peaks are alternately provided in the axial direction. The corrugated tube with high flexibility is covered with the exterior.
The Golgate tube is manufactured in a long length and is used after being cut at a required length. Since the cut end is made of a resin end having rigidity, the Golgate tube has a sharp edge.
When a wire harness composed of a group of electric wires is inserted into the golgate tube, as shown in FIG. 5 (A), in the case of the wire harness 2 in which tape is tightly wound around the outer periphery of the group of wires and protected. Even if interference occurs when the wire harness 2 is pulled out from the cut end 1a of the corrugated tube 1, the wire group is protected with tape, so that the edges do not directly contact the wire and prevent damage to some extent. Can do. However, as shown in FIG. 5 (B), when the wire w is not bound and protected by tape, contact with the cut end 1a of the corrugated tube 1 due to vibration or the like causes damage to the wire w, and the adjacent wire There is a risk of short circuiting between them. In particular, the coating of the non-halo electric wire is easily broken, and interference with the cut end of the corrugated tube is a problem.

前記した問題に対して、本出願人の出願にかかる特開２００２−３６９３３０号（特許文献１）では、図６（Ａ）（Ｂ）に示すように、コルゲートチューブ４の端部に取り付けるエンドキャップ５が提案している。
前記エンドキャップ５は、断面Ｃ字形状の筒体よりなり、コルゲートチューブ４の周縁端部４ａに突き当てる端面部５ａと、該端面部５よりコルゲートチューブ４の外周面に沿って延在する外周壁部５ｂと、コルゲートチューブ４の内周面に沿って延在させる内周壁部５ｃと、外周壁部５ｂの内面より径方向に突設した係止部５ｄと、外周壁部５ｂより径方向に突出し、かつ軸線方向に連続するスリット嵌合部５ｅとを備えている。前記係止部５ｄをコルゲートチューブ４の谷部４ｂに嵌合させると共に、前記スリット嵌合部５ｅをコルゲートチューブ４のスリット４ｃに挿入することにより、軸線方向および周方向の位置ズレを規制してコルゲートチューブ４に取り付けている。 With respect to the above-described problem, in Japanese Patent Application Laid-Open No. 2002-369330 (Patent Document 1) according to the application of the present applicant, as shown in FIGS. 5 has proposed.
The end cap 5 is a cylindrical body having a C-shaped cross section, and an end surface portion 5 a that abuts on the peripheral edge portion 4 a of the corrugated tube 4, and an outer periphery that extends from the end surface portion 5 along the outer peripheral surface of the corrugated tube 4. Wall portion 5b, inner peripheral wall portion 5c extending along the inner peripheral surface of corrugated tube 4, locking portion 5d projecting radially from the inner surface of outer peripheral wall portion 5b, and radial direction from outer peripheral wall portion 5b And a slit fitting portion 5e continuous in the axial direction. The engaging portion 5d is fitted into the trough portion 4b of the corrugated tube 4, and the slit fitting portion 5e is inserted into the slit 4c of the corrugated tube 4, thereby restricting misalignment in the axial direction and the circumferential direction. It is attached to the corrugated tube 4.

前記エンドキャップ５の内周壁部５ｃは、コルゲートチューブ４と電線６との間に挿入されるため、該内周壁部５ｃの装着箇所については、コルゲートチューブ４の端部と電線６との干渉を防止することができる。しかしながら、このエンドキャップ４は、そもそもコルゲートチューブ４のスリット４ｃが開くことによる電線６のはみ出しや、スリット４ｃで挟みこむことによる電線６の損傷の防止を目的とするものであるため、断面Ｃ字形状よりなり、コルゲートチューブ４の周縁端部４ａを全周にわたって覆う構造ではないため、電線６とコルゲートチューブ４の周縁端部４ａとの干渉を完全に防止することはできない。   Since the inner peripheral wall portion 5c of the end cap 5 is inserted between the corrugated tube 4 and the electric wire 6, interference between the end portion of the corrugated tube 4 and the electric wire 6 is caused at the mounting position of the inner peripheral wall portion 5c. Can be prevented. However, the end cap 4 is intended to prevent the electric wire 6 from protruding due to the opening of the slit 4c of the corrugated tube 4 and damage to the electric wire 6 due to being pinched by the slit 4c. Since it consists of a shape and is not the structure which covers the peripheral edge part 4a of the corrugated tube 4 over a perimeter, interference with the electric wire 6 and the peripheral edge part 4a of the corrugated tube 4 cannot be prevented completely.

また、特開２０００−１３９５０号（特許文献２）では、図７（Ａ）〜（Ｄ）に示すように、コルゲートチューブ７の固定具８が提案されている。この固定具８は、筒状の本体８ａの上壁の内壁より固定爪８ｂが、下壁の内壁より挿入方向下方へ傾斜自在な傾動片８ｃが突設されると共に、該本体８ａの開口部８ｄから所要寸法離隔した位置の内側に、貫通穴８ｅを設けた仕切り壁８ｆを設けている。   Japanese Patent Laid-Open No. 2000-13950 (Patent Document 2) proposes a fixture 8 for a corrugated tube 7 as shown in FIGS. The fixing tool 8 has a fixing claw 8b protruding from the inner wall of the upper wall of the cylindrical main body 8a, and a tilting piece 8c that can be inclined downward in the insertion direction from the inner wall of the lower wall, and an opening of the main body 8a. A partition wall 8f provided with a through hole 8e is provided inside a position separated from 8d by a required dimension.

この貫通穴８ｅの内径はコルゲートチューブ７の外径よりも小径としているため、この固定具８に、コルゲートチューブ７で外装した電線９を開口部８ｄから挿入すると、コルゲートチューブ７の挿入は前記仕切り壁８ｆに突き当たって止まり、電線９のみが貫通穴８ｅ内に挿通される。また、コルゲートチューブ７は、その谷部７ａに、固定具８の前記固定爪８ｂと前記傾動片８ｃが係合して固定される。   Since the inner diameter of the through-hole 8e is smaller than the outer diameter of the corrugated tube 7, when the electric wire 9 sheathed with the corrugated tube 7 is inserted into the fixture 8 from the opening 8d, the corrugated tube 7 is inserted into the partition. It stops against the wall 8f, and only the electric wire 9 is inserted into the through hole 8e. Further, the corrugated tube 7 is fixed to the trough portion 7a by engaging the fixing claw 8b of the fixture 8 and the tilting piece 8c.

前記固定具８は、前記傾動片８ｃの傾斜により、一定範囲内であれば多種類の径のコルゲートチューブを固定できる。しかしながら、図７（Ｄ）に示すように、該傾動片８ｃが常に上方に付勢されるため、コルゲートチューブ７は上方へ押し上げられ、コルゲートチューブ７の周縁端部７ｂ、特に底側の周縁端部７ｂが電線９と干渉することを防止できない。   The fixture 8 can fix corrugated tubes having various diameters within a certain range due to the inclination of the tilting piece 8c. However, as shown in FIG. 7D, since the tilting piece 8c is always urged upward, the corrugated tube 7 is pushed upward, and the peripheral edge 7b of the corrugated tube 7, particularly the bottom peripheral edge. It cannot prevent that the part 7b interferes with the electric wire 9.

よって、コルゲートチューブがプロテクタに連続して設けられ、該コルゲートチューブの先端がプロテクタ内に挿入され、該コルゲートチューブの先端から電線が引き出されてプロテクタ内に挿通させる場合においても、前記特許文献２に相当する構成とすると、電線群とコルゲートチューブの端部との干渉を防止できない。   Therefore, even in the case where the corrugated tube is provided continuously to the protector, the tip of the corrugated tube is inserted into the protector, and the electric wire is drawn out from the tip of the corrugated tube and inserted into the protector, the Patent Document 2 If it is set as the corresponding structure, interference with an electric wire group and the edge part of a corrugated tube cannot be prevented.

本発明は前記問題に鑑みてなされたもので、コルゲートチューブの端部のエッジとの干渉による電線被覆の破損を防止することができるワイヤハーネスの保護構造の提供を課題としている。   This invention is made | formed in view of the said problem, and makes it the subject to provide the protection structure of the wire harness which can prevent the failure | damage of the electric wire coating | cover by interference with the edge of the edge part of a corrugated tube.

前記課題を解決するために、本発明は、周壁に山部と谷部とが交互に形成されているコルゲートチューブの切断端からワイヤハーネスを突出させ、底壁と両側壁とを有する樹脂成形品からなるボックス形状のプロテクタ内に挿通させるワイヤハーネスの保護構造であって、
前記プロテクタは樋形状のプロテクタ本体と、該プロテクタ本体の上方開口を閉鎖する蓋体とからなり、前記プロテクタ本体の少なくとも底壁内面には、コルゲートチューブの挿入口からコルゲートチューブの挿入側先端に達するまでの位置に、コルゲートチューブの谷部に嵌合する位置決めリブを突設している一方、前記蓋体にはリブは突設しておらず、
かつ、前記コルゲートチューブの挿入側先端に当たる位置の前記プロテクタ本体の底壁から保護リブを突設し、該保護リブの上面からワイヤハーネス挿通溝を凹設し、該ワイヤハーネス挿通溝の底部の高さは前記位置決めリブで嵌合保持されたコルゲートチューブの谷部の底側の先端エッジより高い位置に設定し、
前記ワイヤハーネス挿通溝にコルゲートチューブの先端より突出するワイヤハーネスを挿通保持して、コルゲートチューブの先端エッジにワイヤハーネスの電線を接触させない構成としていることを特徴とするワイヤハーネスの保護構造を提供している。 In order to solve the above-mentioned problem, the present invention provides a resin molded article having a bottom wall and both side walls projecting from a cut end of a corrugated tube in which crests and troughs are alternately formed on a peripheral wall. A wire harness protection structure that is inserted into a box-shaped protector comprising:
The protector comprises a bowl-shaped protector main body and a lid for closing the upper opening of the protector main body , and reaches at least the inner surface of the bottom wall of the protector main body from the corrugated tube insertion port to the insertion end of the corrugated tube. While the positioning rib that fits into the trough of the corrugated tube protrudes at the position up to, the rib does not protrude from the lid,
And said projecting protective rib from the bottom wall of the protector body position corresponding to the insertion side leading end of the corrugated tube, recessed a wire harness insertion groove from the upper surface of the protective rib, high in the bottom of the wire harness insertion groove The height is set to a position higher than the tip edge on the bottom side of the valley portion of the corrugated tube fitted and held by the positioning rib,
Provided is a wire harness protection structure characterized in that a wire harness protruding from the tip of a corrugated tube is inserted and held in the wire harness insertion groove so that the wire harness electric wire does not contact the tip edge of the corrugated tube. ing.

即ち、コルゲートチューブの切断端と、該切断端から突出したワイヤハーネスの電線群をプロテクタ内に挿通させるとともに、該プロテクタ内の前記保護リブに凹設したワイヤハーネス挿通溝の底部の高さを、前記位置決めリブに嵌合されたコルゲートチューブの谷部よりも高い位置とすることにより、このワイヤハーネス挿通溝に挿入保持された電線は、コルゲートチューブの底側の先端エッジよりも常に上方に位置し、該エッジと干渉しないように保持されるため、電線被覆の破損やそれに因るショートを防止できる。   That is, the cutting end of the corrugated tube and the wire harness electric wire group protruding from the cutting end are inserted into the protector, and the height of the bottom portion of the wire harness insertion groove recessed in the protective rib in the protector is set, By setting the position higher than the trough portion of the corrugated tube fitted to the positioning rib, the electric wire inserted and held in the wire harness insertion groove is always positioned above the tip edge on the bottom side of the corrugated tube. Since it is held so as not to interfere with the edge, it is possible to prevent breakage of the wire coating and short circuit caused by it.

前記保護リブに設けるワイヤハーネス挿通溝の周縁より、コルゲートチューブ挿通側に突出させた保護ガイド部を設け、該保護ガイド部の内部にワイヤハーネスを挿通させることが好ましい。
このように、保護リブよりコルゲートチューブ挿通側に屈曲させて突設した保護ガイド部により、コルゲートチューブの先端エッジは該保護ガイド部の下側に引っ掛かるため、コルゲートチューブのくせ付けによる浮き上がりや走行中の振動等による跳ね上がりを規制できる。従って、コルゲートチューブの先端エッジと電線との間に常に保護ガイド部が介在することになり、該先端エッジと電線とが直接干渉し合うことを一層確実に防止できる。 It is preferable to provide a protection guide part that protrudes toward the corrugated tube insertion side from the periphery of the wire harness insertion groove provided in the protection rib, and to insert the wire harness into the protection guide part.
In this way, the leading edge of the corrugated tube is hooked to the lower side of the protective guide part by the protective guide part that is bent and projected from the protective rib to the corrugated tube insertion side. It is possible to regulate the jumping up due to the vibrations. Therefore, the protective guide portion is always interposed between the leading edge of the corrugated tube and the electric wire, and it is possible to more reliably prevent the leading edge and the electric wire from directly interfering with each other.

上述したように、本発明によれば、コルゲートチューブの切断端と、該切断端から突出した電線とをプロテクタに挿入し、該プロテクタ内に設けた保護リブで、電線をコルゲートチューブから遊離した上方位置で保持することにより、コルゲートチューブの先端エッジと電線との干渉、およびそれによる電線被覆の破損やショートを防止できる。   As described above, according to the present invention, the cut end of the corrugated tube and the electric wire protruding from the cut end are inserted into the protector, and the protective rib provided in the protector allows the electric wire to be released from the corrugated tube. By holding in position, it is possible to prevent interference between the tip edge of the corrugated tube and the electric wire, and damage or short-circuiting of the electric wire coating.

また、前記保護ガイド部により、コルゲートチューブの先端エッジの跳ね上がりや浮き上がりを常に規制し、該先端エッジと電線との干渉をより確実に防止できる。   In addition, the protection guide portion always regulates the jumping and lifting of the tip edge of the corrugated tube, and can more reliably prevent interference between the tip edge and the electric wire.

以下、本発明の実施形態を図面を参照して説明する。
図１乃至図４は、本発明の第１実施形態に係るワイヤハーネスの保護構造を示し、ワイヤハーネスＷ／Ｈをコルゲートチューブ１１で外装するとともに、ボックス形状のプロテクタ２１に挿通させている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a wire harness protection structure according to the first embodiment of the present invention, in which a wire harness W / H is externally covered with a corrugated tube 11 and inserted into a box-shaped protector 21.

前記コルゲートチューブ１１は合成樹脂で成形され、周壁に山部１２と谷部１３とを交互に形成して屈曲性および伸縮性を備えている。このコルゲートチューブ１１は所要長さに切断されており、図１に示すように、ワイヤハーネスＷ／Ｈを挿通した後、該コルゲートチューブ１１の一方の切断端１４をワイヤハーネスＷ／Ｈに位置決めのためにテープＴで巻きつけ固定し、他方の切断端１５（先端）から引き出されるワイヤハーネスＷ／Ｈはプロテクタ２１内を挿通させるため、テープ巻きすることなく電線群を引き出している。   The corrugated tube 11 is formed of a synthetic resin, and has ridges 12 and valleys 13 alternately formed on the peripheral wall to provide flexibility and stretchability. The corrugated tube 11 is cut to a required length. As shown in FIG. 1, after the wire harness W / H is inserted, one cut end 14 of the corrugated tube 11 is positioned to the wire harness W / H. For this purpose, the wire harness W / H, which is wound and fixed with the tape T and pulled out from the other cut end 15 (tip), is inserted through the protector 21, so that the wire group is pulled out without being wound with tape.

前記プロテクタ２１は樹脂で一体成形され、図１および図３に示すように、樋形状のプロテクタ本体２２と該プロテクタ本体２２の上方開口を閉鎖する蓋体２３とを、一端側ではヒンジ２４を介して連結し、他端側ではロック部２５と被ロック部２６とで開閉自在にロック結合している。   The protector 21 is integrally formed of resin. As shown in FIGS. 1 and 3, a protector body 22 having a bowl shape and a lid 23 that closes an upper opening of the protector body 22 are disposed at one end via a hinge 24. At the other end side, the lock part 25 and the locked part 26 are lock-coupled so as to be opened and closed.

前記プロテクタ本体２２は、長手方向の両端を開口しており、一端側はコルゲートチューブ挿入口２７とし、他端側をワイヤハーネス導出口２８としている。プロテクタ本体２２の内部のワイヤハーネス挿入口２７の近傍には、コルゲートチューブ１１の谷部１３と嵌合する複数の位置決めリブ２９を長手方向に並設している。位置決めリブ２９の形成箇所は、具体的には、図２にも示すように、コルゲートチューブ１１を挿通した状態における該コルゲートチューブ１１の挿入側先端１５の位置からワイヤハーネス挿入口２７までの領域の少なくとも一部としている。
前記位置決めリブ２９は、プロテクタ本体２２の底壁２２ａおよび両側壁２２ｂ、２２ｃの内面より連続的に突設され、断面略Ｕ字形状としている。 The protector main body 22 is open at both ends in the longitudinal direction, one end side is a corrugated tube insertion port 27, and the other end side is a wire harness outlet port 28. In the vicinity of the wire harness insertion port 27 inside the protector main body 22, a plurality of positioning ribs 29 that are fitted to the valley portions 13 of the corrugated tube 11 are arranged side by side in the longitudinal direction. Specifically, as shown in FIG. 2, the positioning rib 29 is formed in a region from the position of the insertion-side tip 15 of the corrugated tube 11 to the wire harness insertion port 27 in a state where the corrugated tube 11 is inserted. At least part of it.
The positioning rib 29 protrudes continuously from the bottom wall 22a of the protector body 22 and the inner surfaces of both side walls 22b, 22c, and has a substantially U-shaped cross section.

また、プロテクタ本体２２の内部には、図２および図４に示すように、プロテクタ本体２２にコルゲートチューブ１１を挿通した状態における該コルゲートチューブ１１の挿入側先端１５に当たる位置に、断面略Ｕ字形状の保護リブ３０を形成している。   Further, as shown in FIGS. 2 and 4, the protector main body 22 has a substantially U-shaped cross section at a position where the corrugated tube 11 is inserted into the protector main body 22 in a state where the corrugated tube 11 is inserted. The protective rib 30 is formed.

詳しくは、前記保護リブ３０は、プロテクタ本体２２の底壁２２ａおよび両側壁２２ｂ、２２ｃの内面より連続的に、かつワイヤハーネスＷ／Ｈの挿通方向に対して直交するように突設されている。また、該保護リブ３０の上面より断面Ｕ字状のワイヤハーネス挿通溝３１を凹設するとともに、該ワイヤハーネス挿通溝３１の周縁に沿って保護リブ３０をＬ字状に屈曲させて、コルゲートチューブ挿通側に保護ガイド部３２を突出させている。前記ワイヤハーネス挿通溝３１は、その内径をコルゲートチューブ１１の外径よりも小寸とすると共に、図４に示すように、その底部３１ａの高さＨ１が、コルゲートチューブ１１の谷部１３を前記位置決めリブ２９に嵌合させた状態における該コルゲートチューブ１１の谷部１３の高さＨ２よりも高くなるように形成している。   Specifically, the protective rib 30 projects from the bottom wall 22a of the protector body 22 and the inner surfaces of the side walls 22b and 22c so as to be perpendicular to the insertion direction of the wire harness W / H. . Further, a wire harness insertion groove 31 having a U-shaped cross section is recessed from the upper surface of the protection rib 30, and the protection rib 30 is bent in an L shape along the periphery of the wire harness insertion groove 31. The protection guide part 32 is protruded on the insertion side. The wire harness insertion groove 31 has an inner diameter smaller than the outer diameter of the corrugated tube 11 and, as shown in FIG. The corrugated tube 11 is formed so as to be higher than the height H <b> 2 of the valley portion 13 in the state where the corrugated tube 11 is fitted to the positioning rib 29.

前記構成のプロテクタ２１にコルゲートチューブ１１に外装されたワイヤハーネスＷ／Ｈを挿通すると、ワイヤハーネスＷ／Ｈは前記保護リブ３０のワイヤハーネス挿通溝３１によって高位置に保持されるとともに、前記コルゲートチューブ１１の挿入側先端１５の底側は保護ガイド部３２の下側に引っ掛かって納まる。従って、振動等により最も干渉しやすく損傷しやすいワイヤハーネスＷ／Ｈの底側とコルゲートチューブ１１の切断端１５とを接触させないうえ、コルゲートチューブ１１の切断端１５の跳ね上がりや浮き上がりを保護ガイド部３２が常に規制するため、ワイヤハーネスＷ／Ｈの電線ｗとコルゲートチューブ１１の切断端との干渉を常時防ぎ、電線ｗの絶縁被覆の破れやそれに起因するショートをより確実に防止できる。   When the wire harness W / H sheathed on the corrugated tube 11 is inserted into the protector 21 having the above configuration, the wire harness W / H is held at a high position by the wire harness insertion groove 31 of the protective rib 30 and the corrugated tube 11 is inserted into the bottom side of the protective guide portion 32 so as to be stored. Therefore, the bottom side of the wire harness W / H that is most likely to be interfered with and damaged by vibration or the like and the cut end 15 of the corrugated tube 11 are not brought into contact with each other, and the jumping or floating of the cut end 15 of the corrugated tube 11 is prevented. Therefore, the interference between the wire w of the wire harness W / H and the cut end of the corrugated tube 11 can be prevented at all times, and the insulation coating of the wire w can be more reliably prevented from being broken or short-circuited.
