Description

ワイヤハーネスwire harness
　本発明は、ワイヤハーネスに関する。 The present invention relates to a wire harness.
　従来から、複数の電線を有する幹線及び幹線の分岐部から分岐された分岐線を有する電線群と、電線群の分岐部に取り付けられるとともに車両の特定の対象に固定されるクリップと、を備えたワイヤハーネスが提案されている（例えば、特許文献１を参照）。 Conventionally, electric wires have been provided with a main line having a plurality of electric wires, an electric wire group having a branch line branched from a branch part of the main line, and a clip that is attached to the branch part of the electric wire group and fixed to a specific object of a vehicle. Wire harnesses have been proposed (see, for example, Patent Document 1).
日本国特開２０１０－２００５７７号公報Japanese Patent Publication No. 2010-200577
　特許文献１に記載のワイヤハーネスが有するクリップは、幹線に固定される幹線側基板と、分岐線に固定される分岐線側基板と、を有する。幹線と幹線側基板とはバンドを用いて結束固定され、分岐線と分岐線側基板とはバンドを用いて結束固定される。更に、他の形態として、幹線と幹線側基板とがテープを用いて共巻きされ、分岐線と分岐線側基板とがテープを用いて共巻きされる。 The clip included in the wire harness described in Patent Document 1 includes a main line side board fixed to a main line and a branch line side board fixed to a branch line. The main line and the main line side board are bound and fixed using a band, and the branch line and the branch line side board are tied and fixed using a band. Furthermore, as another form, the main line and the main line side board are co-wound using tape, and the branch line and the branch line side board are co-wound using tape.
　ここで、幹線は一般に径が大きいため、テープ巻きの際にテープと幹線との接触面積が大きい。そのため、幹線では、車両の振動等に起因する外力がワイヤハーネスに及んだ場合であっても、幹線と幹線側基板とがテープで固定された状態を強固に維持される。しかし、分岐線は一般に径が小さいため、テープ巻きの際にテープと分岐線との接触面積が小さい。そのため、分岐線では、外力がワイヤハーネスに及んだ場合、分岐線と分岐線側基板とがテープで固定された状態が解除され得る。 Here, since the diameter of the main line is generally large, the contact area between the tape and the main line is large during tape winding. Therefore, in the main line, even if an external force due to vehicle vibration or the like is applied to the wire harness, the state in which the main line and the main line side board are firmly fixed with the tape is maintained. However, since the branch wire generally has a small diameter, the contact area between the tape and the branch wire during tape winding is small. Therefore, in the branch line, when an external force is applied to the wire harness, the state in which the branch line and the branch line side board are fixed with the tape may be released.
　そこで、幹線及び分岐線の双方においてバンドを用いた結束固定を行うことが考えられる。しかし、結束固定のためのバンドは、一般に、帯状のバンド本体と、バンド本体が対象物を束ねた状態でバンド本体に係合する固定リングと、を要する。そのため、テープによる単純な共巻きに比べ、バンドによる結束固定は、高コストであるし、クリップの構造を複雑化する要因となり得る。 Therefore, it is conceivable to use bands to bind and secure both the main line and the branch line. However, a band for binding and fixing generally requires a belt-shaped band body and a fixing ring that engages with the band body while the band body bundles the object. Therefore, compared to simple co-winding with tape, binding and fixing with a band is costly and may complicate the structure of the clip.
　本発明の目的の一つは、幹線及び分岐線にクリップを適正に固定するとともに、クリップの構造の単純化とクリップの製造コストの低減とを両立可能なワイヤハーネスを提供することにある。 One of the objects of the present invention is to provide a wire harness that can properly fix clips to main lines and branch lines, as well as simplify the structure of the clip and reduce the manufacturing cost of the clip.
　前述した目的を達成するために、本発明に係るワイヤハーネスは、以下を特徴としている。 In order to achieve the above-mentioned object, the wire harness according to the present invention has the following features.

Note that the present invention is not limited to the embodiments shown below, and can be modified as appropriate without departing from the spirit of the present invention. In addition, in the embodiments described below, illustrations and explanations of some components are omitted, but the details of the omitted techniques will be described within the scope of not contradicting the content described below. It goes without saying that publicly known or well-known techniques are applied as appropriate.
　図１は、本発明の実施形態に係るワイヤハーネスを示す斜視図であり、図２は、図１に示したワイヤハーネスの一部構成の平面図であり、図３は、図２のＡ－Ａ断面図である。 FIG. 1 is a perspective view showing a wire harness according to an embodiment of the present invention, FIG. 2 is a plan view of a partial configuration of the wire harness shown in FIG. It is an A sectional view.
　図１に示すように、ワイヤハーネス１は、電線群１０と、クリップ２０と、を備える。ワイヤハーネス１は、車両の特定の取付対象（例えば、車両パネル）に対して固定される。 As shown in FIG. 1, the wire harness 1 includes a wire group 10 and a clip 20. The wire harness 1 is fixed to a specific attachment target (for example, a vehicle panel) of a vehicle.
　電線群１０は、複数の電線によって構成される幹線１１と、幹線１１の分岐部Ｂから分岐する分岐線１２と、を備えている。幹線１１は、根元側の幹線１１ａと、先端側の幹線１１ｂと、を備えている。分岐部Ｂは、根元側の幹線１１ａと先端側の幹線１１ｂとの接続部分に位置する部位である。分岐線１２は、例えば幹線１１よりも少ない本数の電線によって構成される。そのため、分岐線１２は、幹線１１よりも電線径が小さい。分岐線１２は、第１分岐線１２ａと第２分岐線１２ｂとを有している。第１分岐線１２ａと第２分岐線１２ｂとは、幹線１１の分岐部Ｂから、それぞれ異なる方向に延びている。 The electric wire group 10 includes a main line 11 made up of a plurality of electric wires, and a branch line 12 branching from a branch part B of the main line 11. The main line 11 includes a main line 11a on the base side and a main line 11b on the tip side. The branch part B is a part located at the connection part between the main line 11a on the root side and the main line 11b on the tip side. The branch line 12 is configured with fewer electric wires than the main line 11, for example. Therefore, the branch line 12 has a smaller wire diameter than the main line 11. The branch line 12 has a first branch line 12a and a second branch line 12b. The first branch line 12a and the second branch line 12b extend in different directions from the branch B of the trunk line 11, respectively.
　図２及び図３に示すように、クリップ２０は、分岐部Ｂ（図１参照）にクリップ２０を取り付け可能な構造を有している。具体的には、クリップ２０は、電線群１０を載置する載置部Ｐと、車両の特定の取付対象にクリップ２０を取り付けるための取付部Ｍと、を備えている。 As shown in FIGS. 2 and 3, the clip 20 has a structure that allows the clip 20 to be attached to the branch B (see FIG. 1). Specifically, the clip 20 includes a placement part P on which the wire group 10 is placed, and an attachment part M for attaching the clip 20 to a specific attachment target of the vehicle.
　図２に示すように、載置部Ｐは、幹線１１を載置する延出部２１と、分岐線１２を載置する分岐線支持部２２と、分岐線支持部２２の先端部に設けられるバンド部２３，２４と、を備えている。 As shown in FIG. 2, the placing part P is provided at the extension part 21 on which the main line 11 is placed, the branch line support part 22 on which the branch line 12 is placed, and the tip of the branch line support part 22. Band parts 23 and 24 are provided.
　図１に示すように、延出部２１は、根元側の幹線１１ａの軸方向に沿うように配置されて根元側の幹線１１ａを載置するための根元側延出部２１ａと、先端側の幹線１１ｂの軸方向に沿うように配置されて先端側の幹線１１ｂを載置する先端側延出部２１ｂと、を備えている。根元側延出部２１ａは、粘着テープＴによって根元側の幹線１１ａに共巻きされ、先端側延出部２１ｂは、粘着テープＴによって先端側の幹線１１ｂに共巻きされる。延出部２１は、剛性を有する板材であってもよいし、テープ巻きされたときに幹線１１の周方向に沿うように形状変化するような柔軟性を有した部材であってもよい。 As shown in FIG. 1, the extending portion 21 includes a root-side extending portion 21a arranged along the axial direction of the root-side main line 11a on which the root-side main line 11a is placed, and a distal-side extending portion 21a on which the root-side main line 11a is placed. It includes a distal end side extension portion 21b that is arranged along the axial direction of the main line 11b and on which the distal side main line 11b is placed. The base side extension part 21a is co-wound with adhesive tape T around the base side main line 11a, and the tip side extension part 21b is co-wound with adhesive tape T around the distal side main line 11b. The extending portion 21 may be a rigid plate material, or may be a flexible member that changes shape along the circumferential direction of the main line 11 when wrapped with tape.
　なお、根元側延出部２１ａ及び先端側延出部２１ｂは、互いに独立した粘着テープＴで共巻きされてもよいし、連続した一繋がりの粘着テープＴで一括して共巻きされてもよい。例えば、図１では、分岐部Ｂを跨ぐように延びる一繋がりの粘着テープＴにより、根元側延出部２１ａ及び先端側延出部２１ｂがテープ巻きされている。このような一繋がりの粘着テープＴで分岐部Ｂを跨いでテープ巻きを施すことで、分岐部Ｂで幹線１１や分岐線１２が束ねられた状態を強固に保つことができる。 Note that the base side extension part 21a and the tip side extension part 21b may be co-wound with mutually independent adhesive tapes T, or may be co-wound with a continuous series of adhesive tapes T. . For example, in FIG. 1, the base side extension part 21a and the tip side extension part 21b are wrapped with a continuous adhesive tape T extending so as to straddle the branch part B. By wrapping such a continuous adhesive tape T across the branch part B, the state in which the trunk line 11 and the branch line 12 are bundled at the branch part B can be firmly maintained.
　図２に示すように、分岐線支持部２２は、第１分岐線１２ａを載置するための第１支持部２２ａと、第２分岐線１２ｂを載置する第２支持部２２ｂと、を備えている。バンド部２３，２４は、第１支持部２２ａに載置された第１分岐線１２ａを結束固定するための第１バンド部２３と、第２支持部２２ｂに載置された第２分岐線１２ｂを結束固定するための第２バンド部２４と、を備えている。各バンド部２３，２４は、長尺のバンド２３ａ，２４ａと、バンド２３ａ，２４ａを挿通のうえ固定する挿通固定部２３ｂ，２４ｂと、を備えている。バンド部２３は第１分岐線１２ａの周方向に沿うように配置されて、バンド部２４は、第２分岐線１２ｂの周方向に沿うように配置される。より具体的には、各支持部２２ａ，２２ｂに載置された各分岐線１２ａ，１２ｂは、バンド２３ａ，２４ａが外周に巻き回され、且つ、挿通固定部２３ｂ，２４ｂに挿通のうえ固定されることで、結束固定されることとなる。 As shown in FIG. 2, the branch line support section 22 includes a first support section 22a on which the first branch line 12a is placed, and a second support section 22b on which the second branch line 12b is placed. ing. The band parts 23 and 24 include a first band part 23 for binding and fixing the first branch line 12a placed on the first support part 22a, and a second branch line 12b placed on the second support part 22b. and a second band portion 24 for binding and fixing. Each of the band parts 23 and 24 includes long bands 23a and 24a, and insertion fixing parts 23b and 24b for inserting and fixing the bands 23a and 24a. The band portion 23 is arranged along the circumferential direction of the first branch line 12a, and the band portion 24 is arranged along the circumferential direction of the second branch line 12b. More specifically, each branch wire 12a, 12b placed on each support part 22a, 22b has a band 23a, 24a wound around its outer periphery, and is inserted and fixed into an insertion fixing part 23b, 24b. By doing so, it is bound and fixed.
　図３に示す取付部Ｍは、軸部２５と、弾性係止部２６と、傘係止部２７と、を備えている。軸部２５は、載置部Ｐからクリップ２０の取付側に向かって延びる部材である。弾性係止部２６は、軸部２５の先端から斜め根元側（載置側）に向かって延びる傾斜片２６ａと、傾斜片２６ａの中間部付近に形成された段部２６ｂと、を備えている。弾性係止部２６は、クリップ２０の取付部Ｍが特定の取付対象である車両パネルの貫通孔に挿入される場合、まず、挿入過程において傾斜片２６ａが軸部２５に近づくように弾性変形する。次いで、貫通孔に対して所定量挿入されると、傾斜片２６ａの挿入が完了して弾性復帰すると共に段部２６ｂが車両パネルに引っ掛かる。 The mounting portion M shown in FIG. 3 includes a shaft portion 25, an elastic locking portion 26, and an umbrella locking portion 27. The shaft portion 25 is a member extending from the placement portion P toward the attachment side of the clip 20. The elastic locking portion 26 includes an inclined piece 26a extending obliquely from the tip of the shaft portion 25 toward the base side (placing side), and a stepped portion 26b formed near the middle portion of the inclined piece 26a. . When the attachment portion M of the clip 20 is inserted into a through hole of a vehicle panel to which it is attached, the elastic locking portion 26 first elastically deforms so that the inclined piece 26a approaches the shaft portion 25 during the insertion process. . Next, when the inclined piece 26a is inserted a predetermined amount into the through-hole, the insertion of the inclined piece 26a is completed and the inclined piece 26a returns elastically, and the stepped part 26b is caught on the vehicle panel.
　傘係止部２７は、軸部２５の根元側（載置側）から、側方且つやや軸部２５の先端側（取付側）に向かって傘状に拡がる部材である。傘係止部２７は、弾性係止部２６の段部２６ｂが車両パネルに引っ掛かった状態において車両側パネルの逆側から車両側パネルを弾性押圧するようになっている。すなわち、弾性係止部２６の段部２６ｂが車両パネルに引っ掛かった状態において、傘係止部２７は、やや側方に広がるように弾性変形して、車両パネルを押圧する。これにより、クリップ２０は、弾性係止部２６の段部２６ｂと傘係止部２７とによって車両側パネルを挟み込むように、車両側パネルに固定されることとなる。 The umbrella locking portion 27 is a member that expands in an umbrella shape from the base side (placement side) of the shaft portion 25 toward the side and slightly toward the tip side (attachment side) of the shaft portion 25. The umbrella locking portion 27 is configured to elastically press the vehicle side panel from the opposite side of the vehicle side panel in a state where the stepped portion 26b of the elastic locking portion 26 is hooked on the vehicle panel. That is, in a state where the stepped portion 26b of the elastic locking portion 26 is caught on the vehicle panel, the umbrella locking portion 27 is elastically deformed so as to spread slightly laterally and press the vehicle panel. Thereby, the clip 20 is fixed to the vehicle side panel so that the vehicle side panel is sandwiched between the stepped portion 26b of the elastic locking portion 26 and the umbrella locking portion 27.
　次いで、図４～図６を参照して、本実施形態に係るワイヤハーネス１の製造方法（クリップ２０の取付方法）を説明する。まず、図４に示すように、ハーネスの配索治具（配索板）上にクリップ２０が配置される。図４に示す例において、配索治具上には４本のフォークＦが設けられている。このため、クリップ２０の根元側延出部２１ａは、第１フォークＦ１と第２フォークＦ２との間に配置され、先端側延出部２１ｂは、第３フォークＦ３と第４フォークＦ４との間に配置される。同様に、第１支持部２２ａは、第１フォークＦ１と第３フォークＦ３との間に配置され、第２支持部２２ｂは、第２フォークＦ２と第４フォークＦ４との間に配置される。 Next, a method for manufacturing the wire harness 1 (a method for attaching the clip 20) according to the present embodiment will be described with reference to FIGS. 4 to 6. First, as shown in FIG. 4, the clip 20 is placed on a harness wiring jig (roping plate). In the example shown in FIG. 4, four forks F are provided on the wiring jig. Therefore, the base side extension part 21a of the clip 20 is arranged between the first fork F1 and the second fork F2, and the tip side extension part 21b is arranged between the third fork F3 and the fourth fork F4. will be placed in Similarly, the first support part 22a is arranged between the first fork F1 and the third fork F3, and the second support part 22b is arranged between the second fork F2 and the fourth fork F4.
　その後、クリップ２０上に、電線群１０の分岐部Ｂが配置させられる。このとき、根元側延出部２１ａ上に根元側の幹線１１ａが載置され、先端側延出部２１ｂ上に先端側の幹線１１ｂが載置される。同様に、第１支持部２２ａ上に第１分岐線１２ａが載置され、第２支持部２２ｂ上に第２分岐線１２ｂが載置される。 After that, the branch part B of the wire group 10 is placed on the clip 20. At this time, the root-side trunk line 11a is placed on the root-side extension part 21a, and the tip-side trunk line 11b is placed on the tip-side extension part 21b. Similarly, the first branch line 12a is placed on the first support part 22a, and the second branch line 12b is placed on the second support part 22b.
　次いで、図５に示すように、第１分岐線１２ａの外周にバンド２３ａが巻き付けられ、挿通固定部２３ｂに挿入されて固定されることで、第１分岐線１２ａがバンド部２３によって結束固定される。同様に、第２分岐線１２ｂの外周にバンド２４ａが巻き付けられ、挿通固定部２４ｂに挿入されて固定されることで、第２分岐線１２ｂがバンド部２４により結束固定される。 Next, as shown in FIG. 5, a band 23a is wrapped around the outer periphery of the first branch line 12a, and is inserted and fixed into the insertion fixing part 23b, so that the first branch line 12a is bound and fixed by the band part 23. Ru. Similarly, a band 24a is wrapped around the outer periphery of the second branch line 12b, and is inserted and fixed into the insertion fixing part 24b, so that the second branch line 12b is bound and fixed by the band part 24.
　その後、図６に示すように、根元側の幹線１１ａと根元側延出部２１ａとが、粘着テープＴを用いて共巻きされる。同様に、先端側の幹線１１ｂと先端側延出部２１ｂとが、粘着テープＴを用いて共巻きされる。これにより、本実施形態に係るワイヤハーネス１が得られる。なお、本例では、図１及び図６の破線に示すように、根元側延出部２１ａ及び先端側延出部２１ｂの双方が連続した一繋がりの粘着テープＴで一括して共巻きされている。しかし、根元側延出部２１ａ及び先端側延出部２１ｂの各々が、互いに独立した粘着テープＴで共巻きされてもよい。 Thereafter, as shown in FIG. 6, the root-side trunk line 11a and the root-side extension portion 21a are co-wound using adhesive tape T. Similarly, the main line 11b on the tip side and the extending portion 21b on the tip side are co-wound using adhesive tape T. Thereby, the wire harness 1 according to this embodiment is obtained. In addition, in this example, as shown by the broken line in FIGS. 1 and 6, both the base side extension part 21a and the tip side extension part 21b are co-wound with a continuous adhesive tape T. There is. However, each of the base side extension part 21a and the tip side extension part 21b may be co-wound with mutually independent adhesive tapes T.
　以上に説明したように、本実施形態に係るワイヤハーネス１によれば、幹線１１とクリップ２０の延出部２１とがテープで共巻きされている。一般に径が大きい幹線１１であれば、テープ巻きによって幹線１１とクリップ２０との固定状態を適正に維持できる。これにより、クリップ２０に設けるバンド部２３，２４の数を減らすことができる。更に、分岐線１２がクリップ２０のバンド部２３，２４によって結束されている。一般に経が小さくテープ巻きが適しにくい分岐線１２にバンド部２３，２４を用いることで、分岐線１２の固定状態を適正に維持できる。よって、バンド部２３，２４の数を減らしつつ、幹線１１及び分岐線１２とクリップ２０とを適正に固定できる。加えて、クリップ２０の構造の単純化と、クリップ２０の製造コストの低減とを、両立することができる。 As explained above, according to the wire harness 1 according to the present embodiment, the trunk line 11 and the extending portion 21 of the clip 20 are co-wound with tape. Generally, if the main line 11 has a large diameter, the fixed state between the main line 11 and the clip 20 can be properly maintained by wrapping with tape. Thereby, the number of band parts 23 and 24 provided on the clip 20 can be reduced. Further, the branch wire 12 is bound by band portions 23 and 24 of the clip 20. By using the band parts 23 and 24 for the branch line 12, which generally has a small warp and is difficult to wrap with tape, the fixed state of the branch line 12 can be maintained appropriately. Therefore, the clip 20 can be properly fixed to the main line 11 and the branch line 12 while reducing the number of band parts 23 and 24. In addition, it is possible to both simplify the structure of the clip 20 and reduce the manufacturing cost of the clip 20.
　更に、クリップ２０は、分岐部Ｂから第１分岐線１２ａの軸方向に沿って延びる第１支持部２２ａと、分岐部Ｂから第２分岐線１２ｂの軸方向に沿って延びる第２支持部２２ｂと、を有する。バンド部２３は、第１支持部２２ａの延出端部に設けられ、バンド部２４は、第２支持部２２ｂの延出端部に設けられる。これにより、分岐部Ｂから離れた位置においても第１分岐線１２ａ及び第２分岐線１２ｂが束ねられた状態を適正に維持することができる。 Furthermore, the clip 20 includes a first support part 22a extending from the branch part B along the axial direction of the first branch line 12a, and a second support part 22b extending from the branch part B along the axial direction of the second branch line 12b. and has. The band portion 23 is provided at the extending end of the first supporting portion 22a, and the band portion 24 is provided at the extending end of the second supporting portion 22b. Thereby, the state in which the first branch line 12a and the second branch line 12b are bundled can be properly maintained even at a position away from the branch part B.
　更に、分岐部Ｂの一方側（根元側）の幹線１１ａの共巻きに用いられる粘着テープＴと、分岐部Ｂの他方側（先端側）の幹線１１ｂの共巻きに用いられる粘着テープＴとが、一繋がりに連続している。これにより、分岐部Ｂで幹線１１や分岐線１２が束ねられた状態を強固に保つことができる。なお、それら粘着テープＴは、互いに独立していてもよい。 Furthermore, the adhesive tape T used for co-winding the main line 11a on one side (base side) of the branch part B, and the adhesive tape T used for co-winding the main line 11b on the other side (tip side) of the branch part B. , are continuous. Thereby, the state in which the main line 11 and the branch line 12 are bundled at the branch part B can be firmly maintained. In addition, these adhesive tapes T may be mutually independent.
　なお、本発明は上記各実施形態に限定されることはなく、本発明の範囲内において種々の変形例を採用できる。例えば、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。 Note that the present invention is not limited to the above embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the embodiments described above, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiments are arbitrary as long as the present invention can be achieved, and are not limited.
　例えば、本実施形態において、分岐線１２ａがバンド部２３で結束固定され、分岐線１２ｂがバンド部２４で結束固定されている。しかし、例えば、分岐線１２が１本の電線で構成される場合には、分岐線１２をバンド部で結束しなくてもよい。即ち、バンド部で結束固定されない分岐線１２が存在してもよい。 For example, in this embodiment, the branch wire 12a is bound and fixed by the band portion 23, and the branch wire 12b is bound and fixed by the band portion 24. However, for example, when the branch line 12 is composed of one electric wire, the branch line 12 does not need to be bound by the band portion. That is, there may be branch lines 12 that are not bound and fixed at the band portion.
　更に、本実施形態において、クリップ２０は、載置部Ｐと取付部Ｍとが一体的に構成されている。しかし、別体として構成された載置部Ｐと取付部Ｍとを組み付けてクリップ２０が構成されてもよい。 Furthermore, in the present embodiment, the clip 20 has a mounting portion P and a mounting portion M integrally configured. However, the clip 20 may be constructed by assembling the mounting portion P and the mounting portion M that are configured separately.
