Description

本発明はワイヤハーネス用プロテクタに関し、詳しくは、プロテクタに貫通するワイヤハーネスの幹線から支線を分岐させる際に、ワイヤハーネスをテープ巻きによって分岐結束しなくても支線の分岐位置を固定できるものである。   The present invention relates to a protector for a wire harness, and more specifically, when a branch line is branched from a trunk line of a wire harness that penetrates the protector, the branch position of the branch line can be fixed without branching and binding the wire harness by tape winding. .

従来、車両に配索されるワイヤハーネスを外部干渉材から保護したりワイヤハーネスの配索ラインを規制したりする目的でプロテクタにワイヤハーネスを貫通している。例えば、特開２００４−２２９３５１号公報（特許文献１）には、図７（Ａ）のように、複数のハーネス引出し端部２、３、４、５を有するプロテクタ１が提案されており、ハーネス引出し端部２、３、４、５には、ワイヤハーネスＷ／Ｈに外装したコルゲートチューブ６、７、８、９の端部６ａ、７ａ、８ａ、９ａを保持する保持手段２ａ、３ａ、４ａ、５ａが設けられている。   2. Description of the Related Art Conventionally, a wire harness is passed through a protector for the purpose of protecting the wire harness routed in a vehicle from an external interference material or restricting the wiring line of the wire harness. For example, Japanese Unexamined Patent Application Publication No. 2004-229351 (Patent Document 1) proposes a protector 1 having a plurality of harness lead-out ends 2, 3, 4, and 5 as shown in FIG. The drawer end portions 2, 3, 4, 5 have holding means 2a, 3a, 4a for holding the end portions 6a, 7a, 8a, 9a of the corrugated tubes 6, 7, 8, 9 sheathed on the wire harness W / H. 5a are provided.

前記構成のプロテクタ１によれば、図７（Ｂ）のように、プロテクタ１から引き出されるワイヤハーネスＷ／Ｈに外装するコルゲートチューブの端部６ａ、７ａ、８ａ、９ａを、ハーネス引出し端部２、３、４、５の保持手段２ａ、３ａ、４ａ、５ａに保持させることができる。しかし、ワイヤハーネスＷ／Ｈの電線束はプロテクタ１内にフリーな状態で挿通されるため、プロテクタ１の中間位置においてワイヤハーネスＷ／Ｈの幹線から支線を分岐させる場合に支線の分岐位置を固定することができない。よって、図８のように、支線Ｗ／Ｈ−２の分岐位置を固定するために、ワイヤハーネスの分岐部の幹線Ｗ／Ｈ−１と支線Ｗ／Ｈ−２の外周に粘着テープＴを巻き付けて分岐結束する必要があり、作業性が良くないという問題がある。また、前記テープ巻きにより分岐結束された支線のワイヤハーネスＷ／Ｈ−２は可動範囲が小さくなるため、ワイヤハーネスＷ／Ｈ−２の車両への組み付けが困難になる場合もある。   According to the protector 1 having the above-described configuration, as shown in FIG. 7B, the corrugated tube ends 6 a, 7 a, 8 a, and 9 a that are externally mounted on the wire harness W / H pulled out from the protector 1 are connected to the harness pull-out end 2. 3, 4 and 5 holding means 2a, 3a, 4a and 5a can be held. However, since the wire bundle of the wire harness W / H is inserted in the protector 1 in a free state, the branch line branch position is fixed when the branch line is branched from the trunk line of the wire harness W / H at the intermediate position of the protector 1. Can not do it. Therefore, as shown in FIG. 8, in order to fix the branch position of the branch line W / H-2, the adhesive tape T is wound around the outer periphery of the trunk line W / H-1 and the branch line W / H-2 of the branch portion of the wire harness. Therefore, there is a problem that workability is not good. Moreover, since the movable range of the branch wire harness W / H-2 branched and bound by the tape winding is small, it may be difficult to assemble the wire harness W / H-2 to the vehicle.

特開２００４−２２９３５１号公報JP 2004-229351 A

本発明は前記問題に鑑みてなされたものであり、プロテクタ内に貫通するワイヤハーネスの幹線から支線を分岐させる際に、ワイヤハーネスをテープ巻きによって分岐結束しなくても支線の分岐位置を固定できることを課題としている。   The present invention has been made in view of the above problems, and when branching a branch line from a trunk line of a wire harness that penetrates into the protector, the branch position of the branch line can be fixed without branching and binding the wire harness by tape winding.

A branch line outlet is provided in the peripheral wall surrounding the wire harness insertion passage of the protector, and the tip of the corrugated tube that is externally attached to the trunk line is located up to the branching position of the branch line, and a position corresponding to the tip of the corrugated tube A positioning rib that fits into the trough of the corrugated tube is provided on the inner surface of the peripheral wall of the side of the branch outlet of the protector , and is fitted into the trough of the corrugated tube at the tip of the wire harness insertion passage. There is provided a protector for a wire harness characterized in that a positioning rib is provided so as to project, and no positioning rib is provided between a side portion of the branch line outlet and a tip end portion of the wire harness insertion passage .

前記のように、支線分岐位置まで幹線のワイヤハーネスに外装するコルゲートチューブの先端を位置させ、該コルゲートチューブの先端を支線分岐位置近傍のプロテクタの周壁内面に位置決め保持している。これにより、前記コルゲートチューブの先端から引き出されるワイヤハーネスの支線分岐位置はテープ巻きによる分岐結束なしで固定することができ、作業性を高めることができる。また、支線出口から引き出される支線のワイヤハーネスは、テープ巻きによる分岐結束がなされていないため可動範囲が広がり、車両への組み付け等が容易になる。   As described above, the tip of the corrugated tube that is sheathed on the trunk wire harness is positioned up to the branch branch position, and the tip of the corrugated tube is positioned and held on the inner surface of the peripheral wall of the protector near the branch branch position. Thereby, the branch line branch position of the wire harness drawn out from the front-end | tip of the said corrugated tube can be fixed without the branch binding by tape winding, and workability | operativity can be improved. Further, since the branch wire harness pulled out from the branch line outlet is not branched and bound by tape winding, the movable range is widened, and assembling to a vehicle is facilitated.

前記支線出口を挟む両側の周壁内面に前記位置決めリブを突設し、前記幹線の支線分岐位置を挟む両側にコルゲートチューブを外装し、該両側のコルゲートチューブの先端を前記位置決めリブで位置決め保持していることが好ましい。   The positioning ribs project from the inner surfaces of the peripheral walls on both sides sandwiching the branch line outlet, the corrugated tubes are exteriorized on both sides sandwiching the branch branch position of the trunk line, and the tips of the corrugated tubes on both sides are positioned and held by the positioning ribs. Preferably it is.

前記のように、幹線の支線分岐位置を挟む両側にコルゲートチューブを外装し、該両側のコルゲートチューブの先端をプロテクタの支線出口を挟む両側の周壁内面に位置決め保持することにより、支線分岐位置を両側のコルゲートチューブで挟み込んで確実に固定することができる。   As described above, the corrugated tubes are sheathed on both sides of the branch branch position of the trunk line, and the branch branch positions are set on both sides by positioning and holding the tips of the corrugated tubes on both sides of the peripheral wall sandwiching the branch outlet of the protector. The corrugated tube can be securely fixed.

さらに、前記ワイヤハーネス挿通路の両端側に、前記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ことが好ましい。 Furthermore, on both end sides of the wire harness insertion path, it is preferable that the projecting positioning ribs to be fitted to the valley portion of the corrugated tube.

以下、本発明の実施形態を図面を参照して説明する。
図１および図２は本発明の第１実施形態を示している。本実施形態のワイヤハーネス用プロテクタ１０（以下、プロテクタ１０という）は、図１に示すように、ワイヤハーネス挿通路１３を内部に形成したプロテクタ本体１１と、プロテクタ本体１１の上面側開口を覆う蓋体１２とからなり、プロテクタ本体１１および蓋体１２は樹脂成形品から形成している。プロテクタ本体１１の上面側開口に蓋体１２を被せ、ロック部１２ａと被ロック部１１ａとの係合によりプロテクタ本体１１と蓋体１２とを一体化させることができる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show a first embodiment of the present invention. As shown in FIG. 1, a protector 10 for wire harness according to the present embodiment (hereinafter referred to as protector 10) includes a protector main body 11 having a wire harness insertion passage 13 formed therein, and a lid that covers an upper surface side opening of the protector main body 11. The protector body 11 and the lid body 12 are formed of a resin molded product. The protector body 11 and the lid body 12 can be integrated by covering the upper surface side opening of the protector body 11 with the lid body 12 and engaging the lock portion 12a and the locked portion 11a.

プロテクタ本体１１のワイヤハーネス挿通路１３を囲む周壁の中間位置には、ワイヤハーネスの幹線Ｗ／Ｈ−１からＴ字状に分岐させた支線Ｗ／Ｈ−２をプロテクタ１０の外部へ引き出す支線出口１４を設けている。
また、支線出口１４を挟む両側の周壁内面には、ワイヤハーネスの幹線Ｗ／Ｈ−１に外装するコルゲートチューブ３０の谷部３１に嵌合する位置決めリブ１５を突設している。本実施形態では、連続する３個の谷部３１に嵌合するように、円弧状の３個の位置決めリブ１５を並列して設けている。また、蓋体１２内面の対応位置にも、前記谷部３１に嵌合する３個の位置決めリブ１６を設けている。 At the middle position of the peripheral wall surrounding the wire harness insertion passage 13 of the protector body 11, a branch line outlet for drawing out the branch line W / H-2 branched from the trunk line W / H-1 of the wire harness into a T shape to the outside of the protector 10. 14 is provided.
Moreover, the positioning rib 15 which fits into the trough part 31 of the corrugated tube 30 exterior to the trunk line W / H-1 of a wire harness is protrudingly provided in the inner surface of the surrounding wall on both sides which pinches | interposes the branch line exit 14. FIG. In the present embodiment, three arc-shaped positioning ribs 15 are provided in parallel so as to be fitted into three continuous valleys 31. In addition, three positioning ribs 16 that fit into the valley 31 are provided at corresponding positions on the inner surface of the lid 12.

さらに、プロテクタ本体１１のワイヤハーネス挿通路１３両端１３ａ、１３ｂ側の周壁内面にも、位置決めリブ１５と同様の位置決めリブ１７を突設すると共に、蓋体１２内面の対応位置にも位置決めリブ１６と同様の位置決めリブ１８を設けている。   Further, positioning ribs 17 similar to the positioning ribs 15 are provided on the inner surface of the peripheral wall on both ends 13a and 13b of the wire harness insertion passage 13 of the protector body 11, and the positioning ribs 16 are also provided at corresponding positions on the inner surface of the lid body 12. Similar positioning ribs 18 are provided.

図２のように、プロテクタ本体１１のワイヤハーネス挿通路１３にワイヤハーネスの幹線Ｗ／Ｈ−１を貫通させ、支線分岐位置Ａで分岐させた支線Ｗ／Ｈ−２を支線出口１４より引き出している。幹線Ｗ／Ｈ−１の支線分岐位置Ａを挟む両側にコルゲートチューブ３０を外装し、両側のコルゲートチューブ３０の先端の谷部３１に、プロテクタ本体１１の支線出口１４を挟む両側の周壁内面に設けた位置決めリブ１５を夫々嵌合させて位置決め保持している。また、ワイヤハーネス挿通路１３両端１３ａ、１３ｂ側の周壁内面に設けた位置決めリブ１７もコルゲートチューブ３０の谷部３１に嵌合させている。
一方、支線出口１４から引き出した支線Ｗ／Ｈ−２の外周を粘着テープでハーフラップ巻きしている。 As shown in FIG. 2, the trunk line W / H-1 of the wire harness is passed through the wire harness insertion passage 13 of the protector body 11, and the branch line W / H-2 branched at the branch line branching position A is pulled out from the branch line outlet 14. Yes. A corrugated tube 30 is externally provided on both sides of the branch line branching position A of the trunk line W / H-1, and provided on inner surfaces of both peripheral walls sandwiching the branch line outlet 14 of the protector body 11 in the trough 31 at the tip of the corrugated tube 30 on both sides. Each positioning rib 15 is fitted and held. Further, positioning ribs 17 provided on the inner surfaces of the peripheral walls on both ends 13 a, 13 b side of the wire harness insertion passage 13 are also fitted in the valley portions 31 of the corrugated tube 30.
On the other hand, the outer periphery of the branch line W / H-2 pulled out from the branch line outlet 14 is half-wrapped with an adhesive tape.

前記のように、幹線のワイヤハーネスＷ／Ｈ−１に外装する両側のコルゲートチューブ３０の先端を支線分岐位置Ａまで位置させ、両側のコルゲートチューブ３０の先端を、プロテクタの支線出口１４を挟む両側の周壁内面に設けた位置決めリブ１５によって位置決め保持することによって、コルゲートチューブ３０の先端から引き出されるワイヤハーネスＷ／Ｈ−１の支線分岐位置Ａを固定することができる。よって、従来のように、ワイヤハーネスの分岐部をテープ巻きで分岐結束する必要がなくなるため、作業性を高めることができる。また、支線出口１４から引き出される支線Ｗ／Ｈ−２は、テープ巻きによる分岐結束がなされていないため可動範囲が広がり、車両への組み付け等が容易になる。   As described above, the ends of the corrugated tubes 30 on both sides of the main wire harness W / H-1 are positioned up to the branch branch position A, and the ends of the corrugated tubes 30 on both sides sandwich the branch outlet 14 of the protector. By positioning and holding the positioning rib 15 provided on the inner surface of the peripheral wall, the branch line branching position A of the wire harness W / H-1 drawn from the tip of the corrugated tube 30 can be fixed. Therefore, unlike the conventional case, it is not necessary to branch and bind the branch portion of the wire harness by tape winding, so that workability can be improved. Further, the branch line W / H-2 drawn out from the branch line outlet 14 is not branched and bound by tape winding, so that the movable range is widened, and assembling to the vehicle is facilitated.

また、ワイヤハーネス挿通路１３の両端１３ａ、１３ｂ側にもコルゲートチューブ３０の谷部３１に嵌合する位置決めリブ１７を突設しているため、ワイヤハーネスＷ／Ｈ−１に外装するコルゲートチューブ３０を安定した状態でプロテクタ１０内に保持できる。   Moreover, since the positioning rib 17 which fits into the trough part 31 of the corrugated tube 30 is protruded on both ends 13a and 13b side of the wire harness insertion passage 13, the corrugated tube 30 which is externally mounted on the wire harness W / H-1.
