Description

本発明は、電線の外周にコルゲートチューブを配置したワイヤーハーネスの箇所を、所定の配策経路に沿って配策するワイヤーハーネスの配策構造に関する。   The present invention relates to a wire harness routing structure in which a portion of a wire harness having a corrugated tube disposed on the outer periphery of an electric wire is routed along a predetermined routing route.

従来より、全長に亘って蛇腹状に形成されたコルゲートチューブが提案されている。このコルゲートチューブは、電線の保護性とワイヤーハーネスの屈曲性に優れている。従って、ワイヤーハーネスの任意の配策経路に対応できる。しかし、直線区間が長い配策経路では、全長に亘って屈曲性が良いとかえって配策作業性が悪い場合がある。直線区間では、屈曲し易いワイヤーハーネスを直線状態に保持する必要があるためである。   Conventionally, corrugated tubes formed in a bellows shape over the entire length have been proposed. This corrugated tube is excellent in electric wire protection and wire harness flexibility. Therefore, it can respond to any routing route of the wire harness. However, in a routing route with a long straight section, there are cases where the routing workability is poor, although the flexibility is good over the entire length. This is because, in the straight section, it is necessary to keep the wire harness that is easily bent in a straight state.

ここで、コルゲートチューブとして蛇腹状管部と直線管部から成るものが従来より提案されている（例えば特許文献１参照）。このような構成のコルゲートチューブの蛇腹状管部を配策経路の曲線区間に、その直線管部を配策経路の直線区間に配策することが考えられる。   Here, what consists of a bellows-like pipe part and a straight pipe part is proposed conventionally as a corrugated tube (for example, refer patent document 1). It can be considered that the corrugated tube portion of the corrugated tube having such a configuration is routed in the curved section of the routing route, and the straight tube portion is routed in the straight section of the routing route.

しかしながら、前記したコルゲートチューブを使用した場合には、次のような問題がある。つまり、コルゲートチューブは、その直線管部の箇所で屈曲できない。従って、直線経路への組み付け手前位置に干渉物が位置する場合、その干渉物を回避しつつ組み付けることができなかったり、非常に面倒な手順でしか組み付けできなかったりする。そのため、ワイヤーハーネスの配策経路に直線区間があるものでは、配策作業性が劣る場合がある。   However, when the corrugated tube described above is used, there are the following problems. That is, the corrugated tube cannot be bent at the position of the straight tube portion. Therefore, when an interference object is located at a position before assembly to the straight path, the interference object cannot be assembled while avoiding the interference object, or can be assembled only by a very troublesome procedure. Therefore, when there is a straight section in the routing route of the wire harness, the routing workability may be inferior.

そこで、本発明は、前記した課題を解決すべくなされたものであり、ワイヤーハーネスの配策経路に直線区間があるものにあって、配策作業性が良いワイヤーハーネスの配策構造を提供することを目的とする。   Then, this invention is made | formed to solve the above-mentioned subject, and there exists a straight section in the routing route of a wire harness, and provides the routing structure of a wire harness with good routing workability | operativity For the purpose.

本発明は、電線Ｗの外周にコルゲートチューブ１を配置したワイヤーハーネスを、曲線区間と直線区間を有する配策経路に沿って配策するワイヤーハーネスの配策構造であって、前記コルゲートチューブは、周方向の凸部と凹部が軸方向に交互に配置された蛇腹状管部と、軸方向にストレートな壁部が軸方向に配置され、中間位置に屈曲性に優れた屈曲部が介在された直線管部とを備え、前記曲線区間には前記蛇腹状管部を、前記直線区間には前記直線管部を配置したことを特徴する。   The present invention is a wire harness routing structure in which the wire harness having the corrugated tube 1 disposed on the outer periphery of the electric wire W is routed along a routing route having a curved section and a straight section, and the corrugated tube is A bellows-like tube portion in which circumferential convex portions and concave portions are alternately arranged in the axial direction, and a straight wall portion in the axial direction are arranged in the axial direction, and a bent portion having excellent flexibility is interposed at an intermediate position. A straight tube portion, wherein the bellows tube portion is disposed in the curved section, and the straight tube portion is disposed in the straight section.

前記屈曲部は、周方向の凸部と凹部が軸方向に交互に配置された補助蛇腹状管部であることが好ましい。   The bent portion is preferably an auxiliary bellows-like tube portion in which convex portions and concave portions in the circumferential direction are alternately arranged in the axial direction.

本発明によれば、ワイヤーハーネスの直線管部は、その屈曲部の箇所で屈曲できるため、例えば直線経路への組み付け手前位置に干渉物が位置する場合に、その干渉物を回避する形態に変形させることによって容易に直線区間に配策できる。そして、直線区間に配策した状態では、屈曲部以外で屈曲しないため、直線形状を容易に保持できる。以上より、ワイヤーハーネスの配策経路に直線区間があるものにあって、配策作業性が良い。   According to the present invention, since the straight tube portion of the wire harness can be bent at the bent portion, for example, when the interference object is located at a position before assembly to the linear path, the wire harness is deformed to avoid the interference object. By doing so, it is possible to easily arrange a straight section. And in the state arranged in the straight section, since it does not bend except a bending part, a linear shape can be hold | maintained easily. From the above, there is a straight section in the routing route of the wire harness, and the routing workability is good.

以下、本発明の実施形態を図面に基づいて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

（第１実施形態）
図１及び図２は、本発明の第１実施形態を示す。図１において、電線Ｗの外周にコルゲートチューブ１を配置したワイヤーハーネスＷＨ箇所の配策経路は、間隔を置いて配置された２つの曲線区間と、この曲線区間の間に位置する直線区間とから構成されている。各曲線区間の長さ寸法は、Ｌ１とＬ３である。直線区間の長さ寸法は、Ｌ２である。 (First embodiment)
1 and 2 show a first embodiment of the present invention. In FIG. 1, the routing route of the wire harness WH where the corrugated tube 1 is disposed on the outer periphery of the electric wire W is composed of two curved sections arranged at intervals and a straight section located between the curved sections. It is configured. The length dimension of each curve section is L1 and L3. The length dimension of the straight section is L2.

コルゲートチューブ１は、図２に詳しく示すように、両側の蛇腹状管部２，３とこの間に位置する直線管部４とから一体に形成されている。各蛇腹状管部２，３は、周方向の凸部２ａ，３ａと凹部２ｂ，３ｂが軸方向に交互に配置されて形成されている。各蛇腹状管部２，３の長手方向の寸法Ｔ１，Ｔ３は、曲線区間の実質長さＬ１，Ｌ３と同寸法に設定されている。直線管部４は、軸方向に凹凸がなくストレートな壁部が軸方向に配置されて形成されている。直線管部４の長さ寸法Ｔ２は、直線区間の長さＬ２と同寸法に設定されている。直線管部４の中間位置には、屈曲性に優れた屈曲部である補助蛇腹状管部５が介在されている。補助蛇腹状管部５は、周方向の凸部５ａと凹部５ｂが軸方向に交互に配置されて形成されている。直線管部４は、補助蛇腹状管部５を境として２つの蛇腹箇所４Ａ，４Ｂに分割されている。   As shown in detail in FIG. 2, the corrugated tube 1 is integrally formed from the bellows-like tube portions 2 and 3 on both sides and the straight tube portion 4 positioned therebetween. Each of the bellows-like tube portions 2 and 3 is formed by alternately arranging circumferential convex portions 2a and 3a and concave portions 2b and 3b in the axial direction. The lengths T1 and T3 in the longitudinal direction of the bellows-like tube portions 2 and 3 are set to the same dimensions as the substantial lengths L1 and L3 of the curved sections. The straight tube portion 4 is formed by arranging a straight wall portion in the axial direction without irregularities in the axial direction. The length dimension T2 of the straight tube portion 4 is set to the same dimension as the length L2 of the straight section. An auxiliary bellows-like tube portion 5 that is a bent portion having excellent flexibility is interposed at an intermediate position of the straight tube portion 4. The auxiliary bellows-like tube portion 5 is formed by alternately arranging circumferential convex portions 5a and concave portions 5b in the axial direction. The straight tube portion 4 is divided into two bellows locations 4A and 4B with the auxiliary bellows-like tube portion 5 as a boundary.

コルゲートチューブ１で外装されたワイヤーハーネスＷＨの箇所は、各蛇腹状管部２，３が各曲線区間ではその形状に沿った湾曲状に、直線管部４が直線区間では直線状に配置されている。   The location of the wire harness WH sheathed by the corrugated tube 1 is such that the bellows-like tube portions 2 and 3 are arranged in a curved shape along the curved section, and the straight tube portion 4 is arranged in a straight line in the straight section. Yes.

ワイヤーハーネスＷＨは、コルゲートチューブ１の直線管部４の両端位置と、コルゲートチューブ１の各曲線管部２，３の中間位置でそれぞれクランプ部材１０によって車体側に固定されている。   The wire harness WH is fixed to the vehicle body side by a clamp member 10 at both end positions of the straight tube portion 4 of the corrugated tube 1 and at intermediate positions between the curved tube portions 2 and 3 of the corrugated tube 1.

次に、ワイヤーハーネスＷＨの配策作業を説明する。コルゲートチューブ１内に電線Ｗを収容したワイヤーハーネスＷＨを、配策経路上に沿って配策する。ここで、ワイヤーハーネスＷＨの各蛇腹状管部２，３は、自由に屈曲できる。そのため、例えば曲線区間への組み付け手前位置に干渉物が位置する場合にも、その干渉物を回避する形態に変形させることによって容易に曲線区間に配策できる。   Next, the routing work of the wire harness WH will be described. The wire harness WH accommodating the electric wire W in the corrugated tube 1 is routed along the route. Here, each bellows-like pipe part 2 and 3 of wire harness WH can be bent freely. Therefore, for example, even when an interfering object is located at a position before assembly to the curved section, it is possible to easily arrange the curved section by changing the form to avoid the interfering object.

また、ワイヤーハーネスＷＨの直線管部４は、その中間の補助蛇腹状管部５の箇所で屈曲できる。そのため、例えば直線区間への組み付け手前位置に干渉物が位置する場合にも、その干渉物を回避する形態に変形させることによって容易に直線区間に配策できる。そして、直線区間に配策した状態では、直線管部４は、その補助蛇腹状管部５以外で屈曲しないため、直線形状を容易に保持できる。   Further, the straight tube portion 4 of the wire harness WH can be bent at the intermediate auxiliary bellows tube portion 5. Therefore, for example, even when an interfering object is located at a position before assembly to the straight section, it can be easily arranged in the straight section by changing the form to avoid the interfering object. And in the state arranged in the straight section, since the straight pipe part 4 does not bend except the auxiliary bellows-like pipe part 5, it can hold | maintain a straight line shape easily.

その後、ワイヤーハーネスＷＨの適所を各クランプ部材１０によって車体側に固定すれば完了する。   Then, if the appropriate place of the wire harness WH is fixed to the vehicle body side by each clamp member 10, it will be completed.

以上説明したように、ワイヤーハーネスＷＨの配策経路に直線区間があるものにあって、配策作業性が良い。又、ワイヤーハーネスＷＨの直線区間では、その直線形状を保持できるため、車体側へのクランプ数の削減を図ることもできる。   As described above, there is a straight section in the routing route of the wire harness WH, and the routing workability is good. Moreover, since the linear shape can be maintained in the straight section of the wire harness WH, the number of clamps on the vehicle body side can also be reduced.

コルゲートチューブ１の直線管部４には、補助蛇腹状管部５が介在されている。従って、コルゲートチューブ１の直線管部４の両端クランプ位置と、車体側のクランプ位置に位置ずれが発生しても、補助蛇腹状管部５を伸縮させることによって位置合わせが可能である。つまり、補助蛇腹状管部５によってクランプ位置の位置ずれを吸収でき、車体側にクランプの位置ずれ吸収機能を持たせる必要がない。   An auxiliary bellows-like tube portion 5 is interposed in the straight tube portion 4 of the corrugated tube 1. Therefore, even if a misalignment occurs between the clamp positions on both ends of the straight tube portion 4 of the corrugated tube 1 and the clamp position on the vehicle body side, the alignment can be performed by expanding and contracting the auxiliary bellows tube portion 5. That is, it is possible to absorb the displacement of the clamp position by the auxiliary bellows-like tube portion 5, and it is not necessary to provide a clamp displacement absorption function on the vehicle body side.

コルゲートチューブ１の直線管部４は、中間位置に補助蛇腹状管部５を有する。直線区間がその中間位置で折れ曲がったものである場合に、その折れ曲がった位置に補助蛇腹状管部５を設定することにより、「く」の字状に折れ曲がった直線区間にも配策可能できる。   The straight tube portion 4 of the corrugated tube 1 has an auxiliary bellows-like tube portion 5 at an intermediate position. When the straight section is bent at the intermediate position, by setting the auxiliary bellows-like tube portion 5 at the bent position, it is possible to arrange the straight section that is bent in the shape of "<".

屈曲部は、補助蛇腹状管部５にて構成されている。従って、押し出し成形機にあって、蛇腹状管部２，３を作製するコマ部材と同じコマ部材を用いて補助蛇腹状管部５を形成できる。屈曲部は、屈曲性に優れた構造であれば良く、蛇腹構造以外でも良い。   The bent portion is constituted by the auxiliary bellows-like tube portion 5. Therefore, in the extrusion molding machine, the auxiliary bellows-like tube portion 5 can be formed using the same piece member as that for producing the bellows-like tube portions 2 and 3. The bent portion may be a structure having excellent flexibility, and may be other than the bellows structure.

Auxiliary bellows-like tube portions 5 and 7, which are bent portions having excellent flexibility, are interposed at intermediate positions between the straight tube portions 4 and 6. The lengths T1 and T3 in the longitudinal direction of the bellows-like tube portions 2 and 3 are set to the same dimensions as the substantial lengths L1 and L3 of the curved sections. The length dimensions T2 and T4 of each straight tube portion 4 are set to the same dimensions as the lengths L2 and L4 of the straight section. Each of the straight tube portions 4 and 6 is divided into two bellows locations 4A, 4B, 6A and 6B with the auxiliary bellows-like tube portions 5 and 7 as a boundary.
