特開２０１０−４７０３２号公報JP 2010-47032 A

上記従来技術にあっては、外装部材における端末部の位置で導電路がテープ巻きにより固定される。また、導電路は、外装部材に挿通されつつ車両床下の前後位置でプロテクタによっても保持される。外装部材にしろプロテクタにしろ、導電路はこの一端側と他端側とが離れて固定され、そして中間部が外装部材との間に隙間をあけた状態に収容されることから、このような収容状態において、例えば走行時の振動が導電路に伝わった場合には、導電路が振れて外装部材の内面に当たってしまうという虞がある。すなわち、導電路側に削れ等が生じてしまうという虞がある。   In the above prior art, the conductive path is fixed by tape winding at the position of the terminal portion of the exterior member. The conductive path is also held by the protector at the front and rear positions under the vehicle floor while being inserted through the exterior member. Regardless of whether it is an exterior member or a protector, the conductive path is fixed in such a manner that one end side and the other end side are separated from each other, and the intermediate portion is accommodated with a gap between the exterior member and the conductive path. In the housed state, for example, when vibration during traveling is transmitted to the conductive path, the conductive path may swing and hit the inner surface of the exterior member. That is, there is a possibility that the conductive path side may be scraped.

本発明は、上記した事情に鑑みてなされたもので、外装部材内での導電路の動きを抑制することが可能な外装部材と、この外装部材を構成に含むワイヤハーネスとを提供することを課題とする。   This invention is made | formed in view of an above-described situation, and provides the exterior member which can suppress the motion of the conductive path in an exterior member, and the wire harness which includes this exterior member in a structure.

上記課題を解決するためになされた請求項１に記載の本発明の外装部材は、端末部の開口を介して導電路を挿通することにより該導電路を外部から保護する管体形状の外装部材において、当該外装部材は、管軸方向にのびる形状、且つ、前記管軸を中心に周方向に交互に連続して配置される形状の凸部及び凹部を複数有し、さらに、当該外装部材には、前記外部の側から見て凸の形状になる前記複数の凸部を内方に押圧して変形させると、該押圧及び変形の作用により前記複数の凹部が前記導電路との間の隙間を狭めるように前記内方に変形して、前記導電路を保持するための変形保持部が形成される
ことを特徴とする。 The exterior member of the present invention according to claim 1 made to solve the above-described problem is a tubular exterior member that protects the conductive path from the outside by inserting the conductive path through the opening of the terminal portion. The exterior member has a plurality of convex portions and concave portions that have a shape extending in the tube axis direction, and a shape alternately arranged in the circumferential direction around the tube axis. When the plurality of convex portions that are convex when viewed from the outside side are deformed by inward pressing, the plurality of concave portions are spaced from the conductive path by the action of the pressing and deformation. A deformation holding portion for holding the conductive path is formed by deforming inwardly so as to narrow the width.

請求項２に記載の本発明は、請求項１に記載の外装部材において、前記複数の凸部及び前記複数の凹部は、当該外装部材の中間部に配置形成されることを特徴とする。   According to a second aspect of the present invention, in the exterior member according to the first aspect, the plurality of convex portions and the plurality of concave portions are arranged and formed in an intermediate portion of the exterior member.

請求項３に記載の本発明は、請求項１又は２に記載の外装部材において、前記複数の凹部は、前記複数の凸部よりも前記周方向の幅が広く形成されることを特徴とする。   According to a third aspect of the present invention, in the exterior member according to the first or second aspect, the plurality of concave portions are formed wider in the circumferential direction than the plurality of convex portions. .

請求項４に記載の本発明は、請求項１、２又は３に記載の外装部材において、当該外装部材は、前記導電路をストレートに配索する部分としてのストレート管部を有し、該ストレート管部に前記複数の凸部及び前記複数の凹部が形成されることを特徴とする。   According to a fourth aspect of the present invention, in the exterior member according to the first, second, or third aspect, the exterior member has a straight pipe portion as a portion for routing the conductive path in a straight line. The plurality of convex portions and the plurality of concave portions are formed in the tube portion.

請求項５に記載の本発明は、請求項１、２、３又は４に記載の外装部材において、当該外装部材は、腹割きなしの形状に形成されることを特徴とする。   According to a fifth aspect of the present invention, in the exterior member according to the first, second, third, or fourth aspect, the exterior member is formed in a shape without a stomach split.

また、上記課題を解決するためになされた請求項６に記載の本発明のワイヤハーネスは、請求項１、２、３、４又は５に記載の外装部材と、該外装部材に挿通される導電路と、前記外装部材の所定位置で前記外装部材を内方に押圧して変形させるための押圧部材とを備えて構成されることを特徴とする。   Moreover, the wire harness of this invention of Claim 6 made | formed to solve the said subject is the exterior member of Claim 1, 2, 3, 4 or 5, and the electroconductivity penetrated by this exterior member. It is characterized by comprising a path and a pressing member for pressing and deforming the exterior member inward at a predetermined position of the exterior member.

請求項１に記載された本発明によれば、導電路の動きを抑制する必要のある位置で、例えば一括して複数の凸部を内方に押圧して変形させ、そして、この押圧及び変形の作用によって複数の凹部を内方に変形させれば、変形させた複数の凹部で導電路との間の隙間を狭めることができる。すなわち、複数の凹部及び凸部を変形させてなる変形保持部により、導電路を動き難くしたり、導電路を動かないように保持したりすることができる。従って、本発明によれば、所望の位置で外装部材内の導電路の動きを抑制することができ、以て導電路側の削れ等を防止することができるという効果を奏する。   According to the first aspect of the present invention, at a position where it is necessary to suppress the movement of the conductive path, for example, the plurality of convex portions are collectively pressed and deformed, and this pressing and deformation are performed. If the plurality of recesses are deformed inward by the above action, the gap between the conductive paths can be narrowed by the deformed plurality of recesses. That is, it is possible to make the conductive path difficult to move or hold the conductive path so as not to move by the deformation holding portion formed by deforming the plurality of concave portions and convex portions. Therefore, according to the present invention, it is possible to suppress the movement of the conductive path in the exterior member at a desired position, and thus it is possible to prevent the conductive path side from being scraped.

請求項２に記載された本発明によれば、請求項１の効果に加え次のような効果を更に奏する。すなわち、外装部材の中間部の位置では、この内側にある導電路を動き難くしたり、導電路を動かないように保持したりすることができるという効果を奏する。別な言い方をすれば、中間部の位置で外装部材内の導電路の動きを抑制することができ、以て導電路側の削れ等を防止することができるという効果を奏する。   According to the present invention described in claim 2, in addition to the effect of claim 1, the following effect is further exhibited. That is, at the position of the intermediate portion of the exterior member, there is an effect that it is possible to make the conductive path on the inside difficult to move or to hold the conductive path so as not to move. In other words, there is an effect that the movement of the conductive path in the exterior member can be suppressed at the position of the intermediate portion, thereby preventing the conductive path side from being scraped.

請求項３に記載された本発明によれば、請求項１又は２の効果に加え次のような効果を更に奏する。すなわち、複数の凸部の周方向の幅よりも複数の凹部の周方向の幅の方を広く形成することから、複数の凸部を内方に押圧して変形させた時に、この凸部の押圧及び変形の作用による応力を複数の凹部の方に集中させることができる。従って、本発明によれば、複数の凹部を内方に変形させ易くすることができるという効果を奏する。   According to the third aspect of the present invention, in addition to the effect of the first or second aspect, the following effect is further exhibited. That is, since the circumferential width of the plurality of concave portions is formed wider than the circumferential width of the plurality of convex portions, when the plurality of convex portions are pressed inward and deformed, Stress due to the action of pressing and deformation can be concentrated toward the plurality of recesses. Therefore, according to the present invention, there is an effect that the plurality of recesses can be easily deformed inward.

請求項４に記載された本発明によれば、導電路をストレートに配索する部分としてのストレート管部に複数の凸部及び複数の凹部を形成することから、ストレート管部における所望の位置で外装部材内の導電路の動きを抑制することができるという効果を奏する。これにより、例えば車両床下のような長い範囲での導電路の動きを抑制することができ、以て導電路側の削れ等を防止することができるという効果を奏する。   According to the fourth aspect of the present invention, since the plurality of convex portions and the plurality of concave portions are formed in the straight pipe portion as a portion for arranging the conductive path straight, at a desired position in the straight pipe portion. There is an effect that the movement of the conductive path in the exterior member can be suppressed. Thereby, for example, it is possible to suppress the movement of the conductive path in a long range such as under the vehicle floor, and thus it is possible to prevent the conductive path side from being scraped.

請求項５に記載された本発明によれば、請求項１、２、３又は４の効果に加え次のような効果を更に奏する。すなわち、外装部材を腹割きなしの形状に形成することから、防水性及び防塵性等を確保することができ、以て導電路側への悪影響を排除することができるという効果を奏する。   According to the present invention described in claim 5, in addition to the effect of claim 1, 2, 3 or 4, the following effect is further exhibited. In other words, since the exterior member is formed in a shape that does not break, it is possible to ensure waterproofness, dustproofness, and the like, thereby eliminating the adverse effect on the conductive path side.

請求項６に記載された本発明によれば、請求項１、２、３、４又は５に記載の外装部材を含んで構成されることから、ワイヤハーネスとして上記効果を得ることができる。従って、本発明によれば、より良いワイヤハーネスを提供することができるという効果を奏する。   According to the sixth aspect of the present invention, since the exterior member according to the first, second, third, fourth, or fifth aspect is included, the above effect can be obtained as a wire harness.

The straight pipe portion 25 is also formed as a portion that does not bend during packing, transportation, or route routing (the portion that does not bend means a portion that does not actively have flexibility). . The straight pipe portion 25 in the figure is formed in a long straight pipe shape.

ストレート管部２５は、可撓管部２４と比べ、リジッドな部分に形成される。ストレート管部２５は、車両取付形状に合わせた位置や長さに形成される。ストレート管部２５は、本実施例において、少なくとも車両床下１１（図１参照）に配置される部分として形成される。このようなストレート管部２５の中間部になる所定位置には、本発明の特徴部分である複数の凸部２６及び複数の凹部２７が一体に形成される（尚、複数の凸部２６及び複数の凹部２７は、ストレート管部２５の一部として形成されるが、この限りでないものとする。すなわち、複数の凸部２６及び複数の凹部２７のみでストレート管部２５を形成してもよいものとする）。   The straight tube portion 25 is formed in a rigid portion as compared with the flexible tube portion 24. The straight pipe portion 25 is formed in a position and a length according to the vehicle mounting shape. In this embodiment, the straight pipe portion 25 is formed as a portion disposed at least under the vehicle floor 11 (see FIG. 1). A plurality of convex portions 26 and a plurality of concave portions 27 that are characteristic portions of the present invention are integrally formed at a predetermined position that is an intermediate portion of the straight tube portion 25 (note that the plurality of convex portions 26 and the plurality of concave portions The concave portion 27 is formed as a part of the straight tube portion 25, but is not limited thereto, that is, the straight tube portion 25 may be formed by only the plurality of convex portions 26 and the plurality of concave portions 27. And).

図３において、複数の凸部２６及び複数の凹部２７は、管軸方向（図４の中心線ＣＬの延在方向）にのびる形状に形成される。また、このような形状の複数の凸部２６及び複数の凹部２７は、管軸を中心に周方向に交互に連続して配置される。複数の凸部２６及び複数の凹部２７は、この肉厚がストレート管部２５の本体よりも若干薄くなるように形成される（一例であり、同じ肉厚であってもよいものとする）。 <About the several convex part 26 and the several recessed part 27 which are the characteristic parts of this invention>
3, the plurality of convex portions 26 and the plurality of concave portions 27 are formed in a shape extending in the tube axis direction (the extending direction of the center line CL in FIG. 4). The plurality of convex portions 26 and the plurality of concave portions 27 having such a shape are alternately and continuously arranged in the circumferential direction around the tube axis. The plurality of convex portions 26 and the plurality of concave portions 27 are formed so that the thickness is slightly thinner than the main body of the straight tube portion 25 (this is an example, and the same thickness may be used).

尚、図２の引用符号２８は形状変換部を示す。形状変換部２８は、断面円形状の部分から複数の凸部２６及び複数の凹部２７の形状に変換される途中の部分として形成される。   Note that reference numeral 28 in FIG. 2 indicates a shape conversion unit. The shape converting portion 28 is formed as a portion in the middle of being converted from the circular cross-sectional portion into the shapes of the plurality of convex portions 26 and the plurality of concave portions 27.

複数の凸部２６及び複数の凹部２７は、本実施例において、六つずつ形成される（数は一例であるものとする）。複数の凸部２６及び複数の凹部２７は、凸部２６の周方向の幅よりも凹部２７の周方向の幅の方が広くなるように形成される。   In the present embodiment, the plurality of convex portions 26 and the plurality of concave portions 27 are formed six by six (the number is an example). The plurality of convex portions 26 and the plurality of concave portions 27 are formed such that the circumferential width of the concave portions 27 is wider than the circumferential width of the convex portions 26.

尚、凹部２７の形状に関し、図４の中心線ＣＬを基準に円を描いた時に、この円の円弧に一致するような形状に本実施例では形成されるが（別な言い方をすれば外方に凸になる円弧形状に形成されるが）、この形状に限らずに次のような形状に形成されてもよいものとする。すなわち、それぞれの凹部２７が上記とは逆の内方に凸になる円弧形状（上記円の円弧に一致しない形状）に形成されてもよいものとする。凹部２７が内方に変形し易くなる形状であれば特に限定されないものとする。この他、上記円を楕円や長円に読み替えて凹部２７の円弧形状が形成されてもよいものとする。   In addition, regarding the shape of the recess 27, in this embodiment, when a circle is drawn with reference to the center line CL in FIG.

The recess 27 is not particularly limited as long as the recess 27 is easily deformed inward. In addition, the circular shape of the concave portion 27 may be formed by replacing the circle with an ellipse or an ellipse.

＜押圧部材２３について＞
図２及び図４において、押圧部材２３は、外装部材２２における複数の凸部２６及び複数の凹部２７の部分を内方に押圧して変形させるための部材であって、本実施例においては結束バンドが採用される（一例であるものとする）。結束バンドは、以下の説明で分かるようになるが、複数の凸部２６を一括して内方に押圧することができる（均等に締め付け力を生じさせて複数の凸部２６を一括して内方に押圧し変形させることができる）という利点を有する。また、結束バンドは、公知の部材であることから、部材を新設する場合と比べて格段にコスト低減を図ることができるという利点や、信頼性が高いという利点も有する。 <Pressing member 23>
2 and 4, the pressing member 23 is a member for pressing and deforming the portions of the plurality of convex portions 26 and the plurality of concave portions 27 in the exterior member 22, and in the present embodiment, the binding member A band is employed (assuming an example). As will be understood from the following description, the binding band can press the plurality of convex portions 26 inward in a lump (evenly tightening the plurality of convex portions 26 by generating a tightening force). Can be pressed and deformed). Further, since the binding band is a known member, it has an advantage that the cost can be significantly reduced as compared with a case where a member is newly provided and an advantage that the reliability is high.

＜本発明の作用について＞
図４において、複数の凸部２６及び複数の凹部２７の周囲に押圧部材２３を巻き、そして、押圧部材２３の締め付けを行い、複数の凸部２６を一括して内方に押圧すると、この時、図５の矢印に示すような管軸に向けた押圧力（図４の中心線ＣＬに向けた締め付け力）が複数の凸部２６に掛かる。 <About the effect | action of this invention>
In FIG. 4, when the pressing member 23 is wound around the plurality of convex portions 26 and the plurality of concave portions 27, the pressing member 23 is tightened, and the plurality of convex portions 26 are collectively pressed inward, A pressing force directed to the tube axis as shown by an arrow in FIG. 5 (a tightening force toward the center line CL in FIG. 4) is applied to the plurality of convex portions 26.

図６（ａ）及び図７（ａ）において、上記押圧力の作用により複数の凸部２６が内方に変形すると、この押圧及び変形に伴って複数の凹部２７も内方に変形する。この時、複数の凹部２７は三本の導電路２１との間の隙間を狭めるような状態、若しくは接触するような状態に変形する。   6A and 7A, when the plurality of convex portions 26 are deformed inward by the action of the pressing force, the plurality of concave portions 27 are also deformed inward along with the pressing and deformation. At this time, the plurality of recesses 27 are deformed into a state in which a gap between the three conductive paths 21 is narrowed or in a state of contact.

尚、複数の凹部２７は、複数の凸部２６よりも内方に大きく変形する。これは、複数の凸部２６の周方向の幅よりも複数の凹部２７の周方向の幅の方が広く形成されるからである。具体的には、複数の凸部２６を内方に押圧した時に、この押圧力の作用により生じる応力を複数の凹部２７の方に集中させることができるからである（図６（ｂ）及び図７（ｂ）の色の濃い部分が応力の集中度合いが高いことを示す。上記のような幅の関係により、複数の凹部２７を内方に変形させ易くすることができるという利点を有する）。   The plurality of recesses 27 are greatly deformed inward than the plurality of protrusions 26. This is because the circumferential width of the plurality of recesses 27 is formed wider than the circumferential width of the plurality of projections 26. Specifically, when the plurality of convex portions 26 are pressed inward, the stress generated by the action of the pressing force can be concentrated toward the plurality of concave portions 27 (FIG. 6B and FIG. 7 (b) indicates that the dark-colored portion has a high degree of stress concentration, and has the advantage that the plurality of recesses 27 can be easily deformed inward due to the above width relationship).

複数の凸部２６及び複数の凹部２７は、押圧部材２３により内方に変形すると、この変形部分は変形保持部２９として形成される。変形保持部２９は、図示の如く三本の導電路２１を保持する部分として形成される。   When the plurality of convex portions 26 and the plurality of concave portions 27 are deformed inward by the pressing member 23, the deformed portions are formed as deformation holding portions 29. The deformation holding portion 29 is formed as a portion for holding the three conductive paths 21 as shown in the figure.
