Description

本発明は、自動車の所定位置に配索されるワイヤハーネスに関する。 The present invention relates to a wire harness that is laid out at a predetermined position in an automobile.

例えば自動車のエンジンルームには、バッテリーやオルタネータ、リレーボックス等が搭載される。バッテリーの出力端子やオルタネータの出力端子は、リレーボックスに接続される。そして更にリレーボックス及びこのリレーボックスを端末に設けたワイヤハーネスを介して車室内のジャンクションボックスに接続される（例えば下記特許文献１参照）。 For example, a battery, an alternator, a relay box, etc. are installed in the engine room of an automobile. The output terminal of the battery and the output terminal of the alternator are connected to the relay box. Further, the relay box and the relay box are connected to the junction box in the vehicle interior via a wire harness provided on the terminal (see, for example, Patent Document 1 below).

特開２０１４−９７７０９号公報Japanese Unexamined Patent Publication No. 2014-97709

上記リレーボックス及びワイヤハーネスを例に挙げると、ワイヤハーネスは一般的に三次元的な形状に曲げられて配索される。図５及び図６を参照しながら具体的に説明をすると、引用符号１はリレーボックス（電気接続箱）、引用符号２はワイヤハーネス、引用符号３はエンジンルームを示す。ワイヤハーネス２は、ハーネス幹線４と、このハーネス幹線４を保護し且つボディ５（又はパネル）に固定されるプロテクタ６と、図示のハーネス幹線４の中間に設けられる回転クランプ７とを有する。ハーネス幹線４は、リレーボックス１及びプロテクタ６の間で三次元的な形状に曲げられる（略Ｓ字状に曲げられる）。三次元的な形状に曲げられた後、ハーネス幹線４はこの中間が回転クランプ７にて保持される。回転クランプ７は、ブラケット８に対し回転自在に組み付けられる。回転クランプ７は、図５及び図６の紙面垂直方向の軸回りに回転自在な構造を有する（矢印９で示す方向に回転自在）。尚、回転クランプ７でなく回転しないクランプを用いた場合、三次元的な形状に曲げられたハーネス幹線４を保持しつつブラケット８に組み付けようとすると、その作業性が悪くなるのは勿論である。 Taking the relay box and the wire harness as an example, the wire harness is generally bent into a three-dimensional shape and arranged. More specifically with reference to FIGS. 5 and 6, reference code 1 indicates a relay box (electrical connection box), reference mark 2 indicates a wire harness, and reference mark 3 indicates an engine room. The wire harness 2 has a harness trunk line 4, a protector 6 that protects the harness trunk line 4 and is fixed to the body 5 (or a panel), and a rotary clamp 7 provided in the middle of the harness trunk line 4 shown in the figure. The harness trunk line 4 is bent into a three-dimensional shape (bent in a substantially S shape) between the relay box 1 and the protector 6. After being bent into a three-dimensional shape, the harness trunk line 4 is held in the middle by a rotary clamp 7. The rotary clamp 7 is rotatably assembled to the bracket 8. The rotary clamp 7 has a structure that is rotatable around the axis in the direction perpendicular to the paper surface of FIGS. 5 and 6 (rotatable in the direction indicated by the arrow 9). When a non-rotating clamp is used instead of the rotating clamp 7, if an attempt is made to assemble the harness trunk wire 4 bent into a three-dimensional shape to the bracket 8 while holding the harness trunk wire 4, the workability is of course deteriorated. ..

ハーネス幹線４は上記の如く三次元的な形状に曲げられる。例えば図５の場合、紙面垂直方向に凹凸となるようなＳ字状に曲げられる。Ｓ字状に曲げられたハーネス幹線４には、元の状態に戻ろうとする力が作用する。このような状態において、回転クランプ７は矢印９で示す方向に回転し易く、そのためハーネス幹線４は太矢印で示すように図５の状態から図６の状態へと変わってしまうことがある。この時、引用符号１０で示す他の部品が図示の位置に存在していれば、ハーネス幹線４の曲げ可能な曲げ部１１が他の部品１０に干渉してしまうことになる（図６参照）。ハーネス幹線４の干渉があると、例えば走行時の振動を受けることで損傷や破損に繋がってしまう。また、他の部品１０の損傷や破損にも繋がってしまう。ハーネス幹線４が上記状態へと変わってしまうことは、配索状態のバラツキが大きいと言える。尚、図示のハーネス幹線４の長さが寸法公差のプラス側でできているとすると（長めにできているとすると）、曲げ部１１が大きくなることから、その結果、上記バラツキが起こり易くなってしまう。 The harness trunk line 4 is bent into a three-dimensional shape as described above. For example, in the case of FIG. 5, it is bent into an S shape so as to be uneven in the vertical direction of the paper surface. A force that tries to return to the original state acts on the harness trunk line 4 that is bent in an S shape. In such a state, the rotary clamp 7 tends to rotate in the direction indicated by the arrow 9, so that the harness trunk line 4 may change from the state of FIG. 5 to the state of FIG. 6 as shown by the thick arrow. At this time, if the other component indicated by the quotation mark 10 is present at the position shown in the figure, the bendable bending portion 11 of the harness trunk line 4 will interfere with the other component 10 (see FIG. 6). .. If there is interference from the harness trunk line 4, for example, it may be damaged or damaged due to vibration during traveling. It also leads to damage or breakage of the other parts 10. It can be said that there is a large variation in the wiring state when the harness trunk line 4 changes to the above state. If the length of the harness trunk line 4 shown in the figure is made on the plus side of the dimensional tolerance (if it is made longer), the bent portion 11 becomes large, and as a result, the above-mentioned variation is likely to occur. It ends up.

本発明は、上記した事情に鑑みてなされたもので、配索状態のバラツキを抑えて干渉に繋がってしまうのを防止することが可能なワイヤハーネスの提供を課題とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a wire harness capable of suppressing variations in the wiring state and preventing interference.

上記課題を解決するためになされた請求項１に記載の本発明のワイヤハーネスは、第一の固定箇所及び第二の固定箇所を通ってこれらの間に配索されるハーネス幹線、及び、該ハーネス幹線を筒状の外装部材に収容した外装付き幹線のうちいずれか一方と、該いずれか一方における前記第一の固定箇所及び前記第二の固定箇所に対応する第一固定部及び第二固定部の中間に配設され、且つ、取付部位への組み付け方向を軸とした軸回りに回転自在な構造を有する回転クランプとを備え、前記いずれか一方は、前記第一固定部と前記回転クランプとの間の第一区間、及び、前記第二固定部と前記回転クランプとの間の第二区間にそれぞれ曲げ可能な曲げ部が形成され、且つ、該曲げ部にて前記第一固定部から前記第二固定部にかけて全体的に略Ｓ字状に曲げた配索形状にすることが可能に形成され、且つ、前記第一区間及び／又は前記第二区間に前記曲げ部よりも硬質で略ストレートな形状の硬質部が設けられることを特徴とする。 The wire harness of the present invention according to claim 1, which has been made to solve the above problems, includes a harness trunk line routed between the first fixing portion and the second fixing portion, and the harness trunk line.

このような請求項１の特徴を有する本発明によれば、ハーネス幹線に硬質部を設けることから、本来、曲げ部になる部分をなくして略ストレートな形状にすることができる。また、硬質部を設けることから、第一区間及び／又は第二区間において曲げ部の占める割合を小さくするとともに、曲げ部の配置を変えることができ、その結果、回転クランプへの作用を小さくして、回転クランプの回転を起こり難くすることができる。これにより配索状態のバラツキを抑えることができることから、例えば他部品への干渉を防止することができる。 According to the present invention having such a feature of claim 1, since the hard portion is provided on the harness trunk line, it is possible to eliminate the portion that originally becomes the bent portion and form a substantially straight shape. Further, since the hard portion is provided, the proportion of the bent portion in the first section and / or the second section can be reduced, and the arrangement of the bent portion can be changed, and as a result, the action on the rotary clamp is reduced. Therefore, the rotation of the rotary clamp can be made less likely to occur. As a result, it is possible to suppress variations in the wiring state, and thus it is possible to prevent interference with other parts, for example.

請求項２に記載の本発明は、請求項１に記載のワイヤハーネスにおいて、前記第二区間の近傍に干渉を避けたい部品があるとすると、少なくとも前記第一区間側に前記硬質部が配置されることを特徴とする。 According to the second aspect of the present invention, if the wire harness according to the first aspect has a component for which interference is desired to be avoided in the vicinity of the second section, the hard portion is arranged at least on the first section side. It is characterized by that.

このような請求項３の特徴を有する本発明によれば、硬質部に関し、より良い一形態を提供することができる。 According to the present invention having such a feature of claim 3, it is possible to provide a better form with respect to the hard portion.

請求項４に記載の本発明は、請求項３に記載のワイヤハーネスにおいて、前記硬質部である前記硬質チューブは、チューブ軸方向に移動しないように固定されることを特徴とする。 The present invention according to claim 4 is characterized in that, in the wire harness according to claim 3, the hard tube, which is the hard portion, is fixed so as not to move in the tube axial direction.

このような請求項４の特徴を有する本発明によれば、硬質チューブを移動しないように固定することから、例えばワイヤハーネスの配索作業性に影響を来さないようにすることができる。 According to the present invention having such a feature of claim 4, since the hard tube is fixed so as not to move, it is possible to prevent the wiring workability of the wire harness from being affected, for example.

請求項５に記載の本発明は、請求項１、２、３又は４に記載のワイヤハーネスにおいて、前記第一の固定箇所は、電気接続箱のハーネス導出部であり、前記第二の固定箇所は前記電気接続箱から離れて固定されるプロテクタであることを特徴とする。 According to the fifth aspect of the present invention, in the wire harness according to the first, second, third or fourth aspect, the first fixing portion is a harness lead-out portion of an electric junction box, and the second fixing portion is the second fixing portion.

Can be prevented.

本発明のワイヤハーネスによれば、硬質部を設けることで配索状態のバラツキを抑えることができるという効果を奏する。これにより干渉に繋がることを防止し、以てワイヤハーネス自身の損傷や破損、更には干渉を避けたい部品の損傷や破損を防止することができるという効果を奏する。 According to the wire harness of the present invention, it is possible to suppress the variation in the wiring state by providing the hard portion. As a result, it is possible to prevent the wire harness itself from being damaged or damaged, and further to prevent damage or damage to parts for which interference is desired to be avoided.

＜ハーネス幹線２２について＞
図１ないし図４において、ハーネス幹線２２は、特許請求の範囲に記載された「第一の固定箇所」に相当するハーネス導出部２９（後述する）及び「第二の固定箇所」に相当するプロテクタ２４を通って配索される。図示範囲のハーネス幹線２２は、全体的に見ればワイヤハーネス２１における幹線の一部である。ハーネス幹線２２は、本実施例において、一又は複数本の電線と、この電線を覆う筒状の外装部材（コルゲートチューブ等）とを備えて構成される。尚、この構成は特許請求の範囲に記載された「外装付き幹線」の構成に相当するが、ここでは便宜上「ハーネス幹線」の構成とするものとする（特許請求の範囲の記載に合わせれば、例えば上記一又は複数本の電線のみの構成を「ハーネス幹線」と呼び、電線と外装部材（コルゲートチューブ等）とを含む構成を「外装付き幹線」と呼ぶ）。 <About harness trunk line 22>
In FIGS. 1 to 4, the harness trunk line 22 is a harness lead-out unit 29 (described later) corresponding to the “first fixing point” and a protector corresponding to the “second fixing point” described in the claims. It is laid out through 24. The harness trunk line 22 in the illustrated range is a part of the trunk line in the wire harness 21 as a whole. In this embodiment, the harness trunk line 22 includes one or a plurality of electric wires and a tubular exterior member (corrugated tube or the like) that covers the electric wires. It should be noted that this configuration corresponds to the configuration of the "exterior trunk line" described in the claims, but here, for convenience, the configuration is the "harness trunk line" (according to the description of the claims, the configuration is assumed to be the "harness trunk line". For example, the configuration of only one or a plurality of electric wires is referred to as a "harness trunk line", and the configuration including the electric wires and an exterior member (corrugated tube or the like) is referred to as an "exterior trunk line").

ハーネス幹線２２は、三次元的な曲げが可能なものに形成される。また、ハーネス幹線２２は、比較的コシが有るものにも形成される。尚、ハーネス幹線２２を構成する電線には、太物や細物など様々な太さのものがあるが、ここでは特に限定されないものとする。また、電線を構成する導体も銅や銅合金、アルミニウムやアルミニウム合金など様々な金属があるが、特に限定されないものとする。ハーネス幹線２２は、本実施例において、リレーボックス２３のハーネス導出部２９から引き出されるものであるため、複数本の電線を束ね、これをコルゲートチューブに収容してなるものになる。また、ハーネス幹線２２は、エンジンルーム内の配索であるため、水分が掛かったり埃等が付着したりする可能性があるため、コルゲートチューブを構成に含むものになる。 The harness trunk line 22 is formed so that it can be bent three-dimensionally. Further, the harness trunk line 22 is also formed so that it is relatively stiff. The electric wires constituting the harness trunk line 22 have various thicknesses such as thick and thin, but the present invention is not particularly limited. Further, the conductors constituting the electric wire also include various metals such as copper, copper alloy, aluminum and aluminum alloy, but are not particularly limited. Since the harness trunk line 22 is pulled out from the harness lead-out portion 29 of the relay box 23 in this embodiment, a plurality of electric wires are bundled and accommodated in a corrugated tube. Further, since the harness trunk line 22 is arranged in the engine room, there is a possibility that moisture may be applied or dust or the like may adhere to the harness trunk line 22, so that the corrugated tube is included in the configuration.

＜リレーボックス２３について＞

＜硬質チューブ２６（硬質部）について＞
図１ないし図４において、硬質チューブ２６は、ハーネス幹線２２の曲げ可能な曲げ部３３が回転クランプ２５の回転に伴って干渉を避けたい部品２７（図１参照）に対し干渉してしまわないようにするために備えられる。硬質チューブ２６は、曲げ部３３よりも硬質で略ストレートな形状の部材に形成される。ここでハーネス幹線２２の第一固定部３０と回転クランプ２５との間を第一区間Ｓ１、及び、第二固定部３１と回転クランプ２５との間を第二区間Ｓ２と定義し、また、干渉を避けたい部品２７を図１に示すような配置にしたとすると、硬質チューブ２６は少なくとも第一区間Ｓ１に設けられるものとする。硬質チューブ２６は、干渉を避けたい部品２７の配置に応じて、第一区間Ｓ１及び／又は第二区間Ｓ２のハーネス幹線２２に設けられる。硬質チューブ２６は、ハーネス幹線２２を構成する筒状の外装部材（コルゲートチューブ等）よりも若干大きな径の樹脂製で硬質なチューブに形成される。硬質チューブ２６は、上記外装部材に対して図示しないテープ巻きにて軸方向に移動しないように固定される。硬質チューブ２６は、図示の如く第一区間Ｓ１におけるハーネス幹線２２の半分程度を占める長さに形成される。尚、硬質チューブ２６は、配索に必要な曲げ部３３を例えば硬質チューブ２６の両側等に確保できていれば、特に長さは限定されないものとする（但し、作業性や後述する干渉防止の効果に配慮して長さが適宜設定されるものとする）。 <About the hard tube 26 (hard part)>
In FIGS. 1 to 4, in the rigid tube 26, the bendable bending portion 33 of the harness trunk line 22 does not interfere with the component 27 (see FIG. 1) to which interference is desired to be avoided due to the rotation of the rotary clamp 25. Be prepared to. The hard tube 26 is formed of a member having a shape that is harder and substantially straighter than the bent portion 33. Here, the space between the first fixing portion 30 and the rotary clamp 25 of the harness trunk line 22 is defined as the first section S1, and the space between the second fixing portion 31 and the rotary clamp 25 is defined as the second section S2, and they interfere with each other. Assuming that the parts 27 to be avoided are arranged as shown in FIG. 1, the hard tube 26 is provided at least in the first section S1. The hard tube 26 is provided on the harness trunk line 22 of the first section S1 and / or the second section S2 according to the arrangement of the parts 27 for which interference is desired to be avoided. The hard tube 26 is formed of a resin-made hard tube having a diameter slightly larger than that of a tubular exterior member (corrugated tube or the like) constituting the harness trunk line 22. The hard tube 26 is fixed to the exterior member by winding a tape (not shown) so as not to move in the axial direction. As shown in the figure, the hard tube 26 is formed to have a length that occupies about half of the harness trunk line 22 in the first section S1. The length of the hard tube 26 is not particularly limited as long as the bent portions 33 required for wiring can be secured on both sides of the hard tube 26, for example (however, workability and interference prevention described later). The length shall be set appropriately in consideration of the effect).

本実施例の硬質チューブ２６は、ハーネス幹線２２に対し挿通される組み付けのものであるが、このような組み付けの硬質部に限らないものとする。具体的には、柔軟な蛇腹管と硬質なストレート管とを一体成形した硬質部付き外装部材にて代替してもよいものとする。硬質部付き外装部材の場合、組み付け作業を削減できるのは勿論である。硬質部は、本実施例の硬質チューブ２６に限らず、第一区間Ｓ１におけるハーネス幹線２２の中間を曲げ部３３よりも硬質にすることができれば特に限定されないものとする。ハーネス幹線２２は、硬質チューブ２６が設けられていても、第一固定部３０から第二固定部３１にかけて全体的に略Ｓ字状の配索形状に形成されるものとする。 The hard tube 26 of this embodiment is assembled to be inserted through the harness trunk line 22, but is not limited to the hard portion of such an assembly. Specifically, an exterior member with a hard portion, which is integrally molded with a flexible bellows tube and a hard straight tube, may be used instead. In the case of an exterior member with a hard part, it goes without saying that the assembly work can be reduced. The hard portion is not limited to the hard tube 26 of the present embodiment, and is not particularly limited as long as the middle of the harness trunk line 22 in the first section S1 can be made harder than the bent portion 33. Even if the hard tube 26 is provided, the harness trunk line 22 is formed in a substantially S-shaped arrangement shape from the first fixing portion 30 to the second fixing portion 31 as a whole.

本実施例の場合、第一区間Ｓ１における曲げ可能な曲げ部３３の三次元的な曲げ状態がもともと図３及び図４の仮想線で示す状態であるとすると、これに硬質チューブ２６を設けることで図１及び図２の実線で示す状態、すなわち曲げ部３３の大きさを図１及び図２に示すような小さな状態にすることができる。硬質チューブ２６は、第一区間Ｓ１における曲げ部３３の占める割合を小さくするとともに、曲げ部３３の配置を変えることができ、その結果、回転クランプ２５への作用を小さくして回転クランプ２５の回転を起こり難くすることができる。これにより図中の範囲におけるハーネス幹線２２の配索状態のバラツキを抑えることができ、干渉を避けたい部品２７への干渉（第二区間Ｓ２の曲げ部３３による干渉を避けたい部品２７への干渉）を防止することができる。 In the case of this embodiment, assuming that the three-dimensional bending state of the bendable bending portion 33 in the first section S1 is originally the state shown by the virtual lines of FIGS. 3 and 4, a hard tube 26 is provided therein. The state shown by the solid line in FIGS. 1 and 2, that is, the size of the bent portion 33 can be reduced to a small state as shown in FIGS. 1 and 2. The rigid tube 26 can reduce the proportion of the bent portion 33 in the first section S1 and change the arrangement of the bent portion 33, and as a result, reduce the action on the rotary clamp 25 and rotate the rotary clamp 25. Can be made less likely to occur. As a result, it is possible to suppress variations in the wiring state of the harness trunk line 22 in the range shown in the figure, and interfere with the component 27 for which interference is desired to be avoided (interference with the component 27 for which interference due to the bent portion 33 of the second section S2 is desired to be avoided). ) Can be prevented.
