Description
この発明はコルゲートチューブ及びワイヤーハーネス保護構造体に関し、特にその形状を一定に保持する技術に関する。
The present invention relates to a corrugated tube and a wire harness protection structure, and more particularly to a technique for keeping the shape constant.
従来、特許文献１～特許文献４に開示のように、車両等に敷設されるワイヤーハーネスを、屈曲性良好なコルゲートチューブにて覆う技術が知られている。
Conventionally, as disclosed in Patent Documents 1 to 4, a technique of covering a wire harness laid on a vehicle or the like with a corrugated tube having good flexibility is known.
図３は従来のコルゲートチューブ２０を模式的に示す斜視図である。同図に示す様に、コルゲートチューブ２０は長手方向に沿って環状凸部２１と環状凹部２２とが交互に連続形成された蛇腹管状を呈しており内部にワイヤーハーネスＷＨを配設している。
FIG. 3 is a perspective view schematically showing a conventional corrugated tube 20. As shown in the figure, the corrugated tube 20 has an accordion tubular shape in which annular convex portions 21 and annular concave portions 22 are alternately formed along the longitudinal direction, and a wire harness WH is disposed therein.
しかしながら、コルゲートチューブ自体は、屈曲性に優れるもの故、それ自体は内部に配設するワイヤーハーネスの経路を一定に維持する機能を持たない。このため、ワイヤーハーネスあるいはコルゲートチューブに取付けられたクランプ部材を車両の一定位置に固定することで、ワイヤーハーネスの経路を一定に維持する必要がある。クランプ部材の固定箇所が多くなると、部品コスト増、取付けコスト増等を招く恐れがあるという問題点があった。
However, since the corrugated tube itself is excellent in flexibility, the corrugated tube itself does not have a function of maintaining a constant path of the wire harness disposed therein. For this reason, it is necessary to maintain the path | route of a wire harness constant by fixing the clamp member attached to the wire harness or the corrugated tube to the fixed position of a vehicle. When the number of fixing portions of the clamp member is increased, there is a problem in that there is a risk of increasing the component cost and the mounting cost.
ここで、ワイヤーハーネスの敷設箇所に合わせて３次元形状に形成した樋状の樹脂成型品（プロテクタ）によれば、ワイヤーハーネスを保護しつつその経路を一定に維持することができる。

しかしながら、ワイヤーハーネスを保護可能な樹脂成型品を、ワイヤーハーネスの敷設箇所に合わせて３次元形状に形成するためには、その金型形状が複雑化してしまう。このため、製造コストが高くなるという問題点があった。
However, in order to form a resin molded product capable of protecting the wire harness into a three-dimensional shape in accordance with the location where the wire harness is laid, the mold shape becomes complicated. For this reason, there existed a problem that manufacturing cost became high.
この発明は上記問題点を解決するためになされたもので、所望の形状で比較的容易に固定可能なコルゲートチューブ、コルゲートチューブの組立方法及びワイヤーハーネス保護構造体を得ることを目的とする。

1 and 2 are explanatory views showing a cross-sectional structure of a corrugated tube according to an embodiment of the present invention. FIG. 1 shows a case where the axis L1 of the
これらの図に示すように、コルゲートチューブ１内にはワイヤーハーネスＷＨが配設されており、コルゲートチューブ１とワイヤーハーネスＷＨとによりワイヤーハーネス保護構造を構成している。
As shown in these drawings, a wire harness WH is disposed in the corrugated tube 1, and the corrugated tube 1 and the wire harness WH constitute a wire harness protection structure.
ワイヤーハーネスＷＨ、複数の電線が結束された構成とされている。より具体的には、ワイヤーハーネスＷＨは、複数の電線が配設対象となる車両への配線形態に応じて分岐しつつ結束された構成とされている。ワイヤーハーネスＷＨは、必ずしも分岐している必要はなく、また、単一の電線によって構成されていてもよい。また、ワイヤーハーネスＷＨに、他の光ケーブル等が結束されていてもよい。
The wire harness WH and a plurality of electric wires are bundled. More specifically, the wire harness WH has a configuration in which a plurality of electric wires are bundled while being branched according to a wiring form to a vehicle to be disposed. The wire harness WH does not necessarily have to be branched, and may be configured by a single electric wire. Further, another optical cable or the like may be bound to the wire harness WH.
これらの図に示すように、外周面が環状の環状凸部２１と環状凹部２２とによりコルゲートチューブ本体部を構成している。コルゲートチューブ本体部は、長手方向(軸Ｌ１あるいは軸Ｌ２で規定される方向)に沿って環状凸部２１と環状凹部２２とが交互に連続形成されて蛇腹管状を呈している。そして、環状凸部２１及び環状凹部２２の表面を覆って、形状固定部である形状固定用樹脂２３が形成されている。このように、形状固定用樹脂２３を環状凸部２１及び環状凹部２２の実質全表面上に形成することにより、軸Ｌ１及び軸Ｌ２によって規定される３次元形状が固定される。
As shown in these drawings, the corrugated tube main body portion is constituted by the annular convex portion 21 and the annular concave portion 22 whose outer peripheral surfaces are annular. The corrugated tube main body portion has a bellows-like shape in which annular convex portions 21 and annular concave portions 22 are alternately formed continuously along the longitudinal direction (the direction defined by the axis L1 or the axis L2). A shape fixing resin 23 that is a shape fixing portion is formed so as to cover the surfaces of the annular convex portion 21 and the annular concave portion 22. Thus, by forming the shape fixing resin 23 on substantially the entire surface of the annular convex portion 21 and the annular concave portion 22, the three-dimensional shape defined by the axis L1 and the axis L2 is fixed.
図１及び図２において、形状固定用樹脂２３の膜厚は環状凸部２１及び環状凹部２２による凹凸を反映したほぼ均一な膜厚構造で形成されているが、他の構造でもコルゲートチューブ１の３次元形状が固定できれば良い。また、コルゲートチューブ１の３次元形状が固定できるのであれば環状凸部２１及び環状凹部２２の表面の一部に選択的に形状固定用樹脂２３を形成するような構造でも良い。
In FIGS. 1 and 2, the film thickness of the shape fixing resin 23 is formed with a substantially uniform film thickness structure reflecting the irregularities due to the annular protrusions 21 and the annular recesses 22. It is sufficient if the three-dimensional shape can be fixed. Further, as long as the three-dimensional shape of the corrugated tube 1 can be fixed, a structure in which the shape fixing resin 23 is selectively formed on part of the surfaces of the annular convex portion 21 and the annular concave portion 22 may be used.
（組立方法）
以下、本実施の形態のコルゲートチューブ１の車両内への組立方法について説明する。本実施の形態のコルゲートチューブ１の組立方法（製造方法）は以下のステップ(a)、(b) からなる。 (Assembly method)
Hereinafter, a method for assembling thecorrugated tube 1 of the present embodiment into the vehicle will be described. The assembly method (manufacturing method) of the corrugated tube 1 according to the present embodiment includes the following steps (a) and (b).
以下、本実施の形態のコルゲートチューブ１の車両内への組立方法について説明する。本実施の形態のコルゲートチューブ１の組立方法（製造方法）は以下のステップ(a)、(b) からなる。 (Assembly method)
Hereinafter, a method for assembling the
まず、ステップ(a)において、形状固定用樹脂２３が形成される前段階における環状凸部２１及び環状凹部２２からなるコルゲートチューブ本体を、車両内において所望の３次元形状で仮設定する。
First, in step (a), the corrugated tube body composed of the annular convex portion 21 and the annular concave portion 22 in the stage before the shape fixing resin 23 is formed is temporarily set in a desired three-dimensional shape in the vehicle.
形状固定用樹脂２３が形成される前段階におけるコルゲートチューブ本体部は、従来のコルゲートチューブと同様に環状凸部２１と環状凹部２２との間の段差部等で容易に弾性変形するため、コルゲートチューブ本体部として曲げ変形容易な性質を有している。このため、要求されるワイヤーハーネスＷＨを敷設する経路規制に適合した形状（所望の形状）で車両内に比較的用に仮設定することができる。
Since the corrugated tube main body portion before the shape fixing resin 23 is formed is easily elastically deformed at the stepped portion between the annular convex portion 21 and the annular concave portion 22 as in the conventional corrugated tube, the corrugated tube The main body has the property of being easily bent and deformed. For this reason, the shape (desired shape) suitable for the path regulation for laying the required wire harness WH can be temporarily set in the vehicle.
次に、ステップ(b)において、上記所望の形状を維持させた状態で、上記コルゲートチューブ本体部の環状凸部２１及び環状凹部２２の表面を覆って形状固定用樹脂２３を形成する。なお、形状固定用樹脂２３の形成方法としては、真空成形技術を用いて環状凸部２１及び環状凹部２２の表面に樹脂シートをラミネートして形状固定用樹脂２３を得たり、モールド成形技術を用いて環状凸部２１及び環状凹部２２の表面上に形状固定用樹脂２３を形成したりする方法が考えられる。
Next, in step (b), the shape fixing resin 23 is formed so as to cover the surfaces of the annular convex portion 21 and the annular concave portion 22 of the corrugated tube main body portion while maintaining the desired shape. In addition, as a method for forming the shape fixing resin 23, a resin sheet is laminated on the surfaces of the annular convex portion 21 and the annular concave portion 22 by using a vacuum molding technique to obtain the shape fixing resin 23, or a molding technique is used. A method of forming the shape fixing resin 23 on the surfaces of the annular convex portion 21 and the annular concave portion 22 can be considered.
（効果等）
なお、形状固定用樹脂２３の材質としては例えば、ＡＢＳ樹脂、ＰＰ樹脂等が考えられる。また、コルゲートチューブ本体部の材料と同一材料で形状固定用樹脂２３を形成する方が、形状固定用樹脂２３がコルゲートチューブ本体部から剥がれにくい特性を有すため、安定した３次元形状の固定が可能となるため望ましい。また、製造コストの観点からもコルゲートチューブ本体部と形状固定用樹脂２３とは同一材料で形成することが望ましい。 (Effects etc.)
In addition, as a material of theshape fixing resin 23, for example, ABS resin, PP resin, and the like are conceivable. In addition, forming the shape fixing resin 23 with the same material as that of the corrugated tube main body has a characteristic that the shape fixing resin 23 is less likely to be peeled off from the corrugated tube main body. This is desirable because it is possible. Also, from the viewpoint of manufacturing cost, it is desirable that the corrugated tube main body and the shape fixing resin 23 are formed of the same material.
