And a pressing portion 26 that presses.
　環状本体部２５は、前記凹溝が、前述した所望の向きに復元不可となるように屈曲された適宜箇所１０ａの断面形状が扁平に形成されたチューブ１３を収容する幅に形成されている。環状本体部２５は、前記チューブ１３の適宜箇所１０ａで前述した所望の向きに復元不可となるように屈曲させる円板状に形成されている。環状本体部２５は、図示しない加熱手段としての電熱器などを備え、温調器によって前記チューブ１３が軟化する温度に保持されている。なお、電熱器などの電源の取り回しが困難な場合には、他の加熱手段によって適宜箇所１０ａを加熱してもよい。 The annular main body 25 is formed to have a width that accommodates the tube 13 in which the cross-sectional shape of the appropriate portion 10a is flattened so that the concave groove is bent so that it cannot be restored in the desired direction described above. The annular main body 25 is formed in a disk shape that is bent so that it cannot be restored in the desired direction described above at the appropriate portion 10a of the tube 13. The annular main body 25 includes an electric heater as a heating means (not shown), and is held at a temperature at which the tube 13 is softened by a temperature controller. When it is difficult to handle a power source such as an electric heater, the portion 10a may be appropriately heated by other heating means.
　押圧部２６は、前記凹溝の幅方向に延長された円柱形状に形成され、当該凹溝の底部側に設けられている。押圧部２６は、図９に示すように、前記凹溝の周方向に間隔を空けるとともに、同心円上に複数並んで設けられている。押圧部２６は、直径が比較的小さいチューブ１３に対して使用される細径押圧部２６ａと、直径が比較的大きいチューブ１３に対して使用される太径押圧部２６ｂと、を備えている。 The pressing part 26 is formed in a cylindrical shape extending in the width direction of the groove, and is provided on the bottom side of the groove.

To do. Then, an appropriate portion 10a of the tube main body 19 of the tube 13 made of thermoplastic resin is once heated and softened and bent in the desired direction described above. Then, the appropriate portion 10a of the tube main body 19 of the tube 13 is moved away from the outer peripheral surface of the forming jig 21, that is, the concave groove, cooled, and cured in a state bent in the desired direction described above.
　こうして、チューブ１３のチューブ本体１９の適宜箇所１０ａが、前述した所望の向きに復元不可となるように屈曲して、断面形状が扁平に形成される。このとき、チューブ１３のチューブ本体１９の適宜箇所の断面形状が扁平に形成されるので、図１３に示すように、複数本（図示例では、二本）の電線１１の曲率半径がほぼ同じとなり、前記複数本の電線１１同士の線長差の発生が防止される。また、チューブ１３のチューブ本体１９の適宜箇所の断面形状が扁平に形成されるので、前記チューブ本体１９の断面の両端部１９ａ，１９ｂが前記チューブ１３の長手方向の両端で当該長手方向にずれることが防止される。 Thus, the appropriate portion 10a of the tube body 19 of the tube 13 is bent so that it cannot be restored to the desired direction described above, and the cross-sectional shape is formed flat. At this time, since the cross-sectional shape of an appropriate portion of the tube main body 19 of the tube 13 is formed flat, as shown in FIG. 13, the curvature radii of a plurality of (in the illustrated example, two) wires 11 are substantially the same. The occurrence of a difference in wire length between the plurality of electric wires 11 is prevented. Moreover, since the cross-sectional shape of the tube main body 19 of the tube 13 at an appropriate location is formed flat, both end portions 19a and 19b of the cross section of the tube main body 19 are shifted in the longitudinal direction at both ends in the longitudinal direction of the tube 13. Is prevented.

Since the tube main body 19 is formed by being compressed and the plurality of ridges 10c formed by being accommodated in the gaps between the plurality of pressing portions 26 are provided at substantially equal intervals, the ridges 10c are provided. The appearance position of the tube 13 is improved by restricting the generation position. Therefore, the quality of the wire harness 10 is improved.
　このように、ワイヤハーネス１０は、直線状のチューブ１３内に電線１１を収容し、当該チューブ１３の全長に亘ってチューブ本体１９の断面の両端部１９ａ，１９ｂを互いに密に重ねて、当該直線状のチューブ１３の適宜箇所１０ａを前述した向きに復元不可となるように屈曲して、組み立てられる。こうして組み立てられたワイヤハーネス１０は、コネクタ１２が前述したバッテリ５やインバータ４のコネクタに嵌合し、かつチューブ１３が車体フレーム８の下面に取り付けられるなどして、自動車１に配索される。 Thus, the wire harness 10 accommodates the electric wire 11 in the linear tube 13, and the both ends 19a and 19b of the cross section of the tube main body 19 are closely overlapped over the entire length of the tube 13 so that the straight line The appropriate portion 10a of the tubular tube 13 is bent and assembled in the above-described direction so as not to be restored. The wire harness 10 assembled in this manner is routed in the automobile 1 such that the connector 12 is fitted to the connector of the battery 5 or the inverter 4 described above and the tube 13 is attached to the lower surface of the vehicle body frame 8.
　本実施形態によれば、チューブ１３の自動車１に配索される際に屈曲される適宜位置１０ａが自動車１に配索される際に屈曲される所望の向きに復元不可となるように屈曲されているので、ワイヤハーネス１０が自動車１に配索される際に再度チューブ１３を曲げる必要が殆ど生じない。このために、配線用クリップやプロテクタの数を削減でき、部品点数の増加を防止できる。 According to the present embodiment, the appropriate position 10a that is bent when the tube 13 is routed in the automobile 1 is bent so that it cannot be restored to a desired orientation that is bent when the tube 13 is routed in the automobile 1. Therefore, there is almost no need to bend the tube 13 again when the wire harness 10 is routed in the automobile 1. For this reason, the number of wiring clips and protectors can be reduced, and an increase in the number of parts can be prevented.
　また、ワイヤハーネス１０は、自動車１に配索される際に再度曲げる必要が殆ど生じないので、電線１１を必要以上の長さにすることを防止できる。なお、必要な長さとは、自動車１に搭載されるバッテリ５やインバータ４などの電子機器同士を接続するための配索経路の長さをいう。 Further, since the wire harness 10 hardly needs to be bent again when being routed in the automobile 1, it is possible to prevent the wire 11 from being made longer than necessary. The required length refers to the length of the routing path for connecting electronic devices such as the battery 5 and the inverter 4 mounted on the automobile 1.
　チューブ１３に全長に亘ってスリット２０が設けられ、電線１１を収容する際には当該チューブ１３が直線状をなしているので、このチューブ１３内に容易に電線１１を収容することができ、適宜箇所１０ａを屈曲する際に、チューブ１３の全長に亘ってチューブ本体１９の断面の両端部１９ａ，１９ｂが互いに重ねられているので、スリット２０を通してチューブ１３外に電線１１が飛び出ることを防止できる。このために、容易で確実にワイヤハーネス１０を組み立てることができる。 The slit 13 is provided over the entire length of the tube 13, and when the electric wire 11 is accommodated, the tube 13 is linear, so that the electric wire 11 can be easily accommodated in the tube 13, When the portion 10 a is bent, since both end portions 19 a and 19 b of the cross section of the tube main body 19 overlap each other over the entire length of the tube 13, the electric wire 11 can be prevented from jumping out of the tube 13 through the slit 20. For this reason, the wire harness 10 can be assembled easily and reliably.
　チューブ１３が熱可塑性樹脂で構成されかつ適宜箇所１０ａが一旦加熱されて屈曲されているので、チューブ１３の適宜箇所１０ａを自動車１に配索される際に屈曲される向きに復元不可となるように確実に屈曲することができる。このために、電線１１を必要以上の長さにすることを確実に防止でき、配線用クリップやプロテクタの数を確実に削減できて、部品点数の増加を確実に防止できる。 Since the tube 13 is made of a thermoplastic resin and the appropriate portion 10a is once heated and bent, the appropriate portion 10a of the tube 13 cannot be restored to the bent direction when being routed to the automobile 1. Can be bent reliably. For this reason, it is possible to reliably prevent the electric wire 11 from becoming longer than necessary, to reliably reduce the number of wiring clips and protectors, and to reliably prevent an increase in the number of parts.
　チューブ１３の端部と当該チューブ１３内の電線１１との外周に第２テープ１５が巻き付けられているので、これらのチューブ１３と電線１１との相対的な位置がずれることを防止できる。 Since the second tape 15 is wound around the outer periphery of the end portion of the tube 13 and the electric wire 11 in the tube 13, it is possible to prevent the relative positions of the tube 13 and the electric wire 11 from shifting.
　ワイヤハーネスの製造装置３１の成形用治具２１は、直線状のチューブ１３の適宜箇所１０ａが前記自動車１に配索される際に屈曲される向きに復元不可となるように屈曲させる環状部２４には、前記直線状のチューブ１３の前記適宜箇所１０ａが屈曲される向きに復元不可となるように屈曲される際に当該チューブ１３を押圧する複数の押圧部２６が間隔を空けて並設されているので、チューブ１３の曲げられる方向の内側が圧縮されて形成される皺１０ｃを、前記複数の押圧部２６同士の間に形成することができる。従って、前記複数の押圧部２６同士の間に皺１０ｃを形成することによって、当該皺１０ｃの形状が整えられるので、ワイヤハーネス１０の外観と品質とを向上することができる。 The forming jig 21 of the wire harness manufacturing apparatus 31 is an annular portion 24 that bends so that an appropriate portion 10a of the linear tube 13 cannot be restored in a direction in which the straight tube 13 is bent when being routed to the automobile 1. A plurality of pressing portions 26 that press the tube 13 when the appropriate portion 10a of the linear tube 13 is bent so that it cannot be restored in the bending direction are arranged in parallel at intervals. Therefore, the flange 10c formed by compressing the inner side in the bending direction of the tube 13 can be formed between the plurality of pressing portions 26. Therefore, by forming the flange 10c between the plurality of pressing portions 26, the shape of the flange 10c is adjusted, so that the appearance and quality of the wire harness 10 can be improved.
　前述した実施形態では、第２テープ１５をチューブ１３の両端部と電線１１との外周に巻き付けている。しかしながら、本発明では、電線１１とチューブ１３とを相対的に固定できれば、第２テープ１５をチューブ１３の一方の端部のみに巻き付けてもよい。さらに、本発明では、適宜箇所１０ａを前述した所望の向きに復元不可となるように屈曲する際に、例えば、両端部１９ａ，１９ｂの互いに重なる部分の面積を大きくするなどして、スリット２０を通して電線１１がチューブ１３外に排出されることがなければ、第２テープ１５を必ずしも巻き付けなくても良い。さらに、本発明では、ワイヤハーネス１０は、バッテリ５やインバータ４以外の電子機器同士を接続してもよく即ち信号伝送用に用いられてもよく、電線１１を三本以上備えていてもよい。 In the above-described embodiment, the second tape 15 is wound around the outer periphery of both ends of the tube 13 and the electric wire 11. However, in the present invention, the second tape 15 may be wound around only one end of the tube 13 as long as the electric wire 11 and the tube 13 can be relatively fixed. Furthermore, in the present invention, when the portion 10a is appropriately bent so as not to be restored in the desired direction described above, for example, the areas of the overlapping portions of the both end portions 19a and 19b are increased, for example, through the slit 20. If the electric wire 11 is not discharged out of the tube 13, the second tape 15 may not necessarily be wound. Furthermore, in the present invention, the wire harness 10 may connect electronic devices other than the battery 5 and the inverter 4, that is, may be used for signal transmission, and may include three or more electric wires 11.
　また、本発明では、図１５に示すように、ワイヤハーネス１０が、結束部材としてのハーネス用テープ（以下、単にテープという）１４を備えても良い。テープ１４は、一方の表面に粘着層が設けられかつ長尺の帯状に形成されている。テープ１４は、チューブ本体１９即ちチューブ１３の外周に当該チューブ本体１９の全長に亘って巻き付けられて、粘着層が前述した両端部１９ａ，１９ｂが密に重なった状態のチューブ本体１９即ちチューブ１３の外面に密着している。テープ１４は、チューブ１３の全長に亘ってチューブ本体１９の断面の両端部１９ａ，１９ｂが互いに密に重ねられた状態に保つ。 In the present invention, as shown in FIG. 15, the wire harness 10 may include a harness tape 14 (hereinafter simply referred to as a tape) as a binding member. The tape 14 has an adhesive layer on one surface and is formed in a long band shape. The tape 14 is wound around the outer circumference of the tube main body 19, that is, the tube 13, over the entire length of the tube main body 19, and the adhesive layer is in the state of the tube main body 19, that is, the tube 13 in a state where the both end portions 19 a and 19 b are closely overlapped. It is in close contact with the outer surface. The tape 14 keeps both end portions 19 a and 19 b of the cross section of the tube main body 19 closely stacked over the entire length of the tube 13.
　図１５に示すワイヤハーネス１０を組み立てる際には、スリット２０を通してチューブ１３のチューブ本体１９内に電線１１を収容して、第２テープ１５を電線１１の端末とチューブ１３のチューブ本体１９の少なくとも一方の端部の外周に巻き付けた後に、テープ１４をチューブ１３の全長に亘って、チューブ１３のチューブ本体１９に巻き付ける。こうして、電線１１を収容した直線状のチューブ１３の外周にテープ１４を巻き付けて、チューブ１３の全長に亘ってチューブ本体１９の断面の両端部１９ａ，１９ｂを互いに密に重ねた状態にしてから、前述した実施形態と同様に適宜箇所１０ａを屈曲する。 When the wire harness 10 shown in FIG. 15 is assembled, the electric wire 11 is accommodated in the tube main body 19 of the tube 13 through the slit 20, and the second tape 15 is attached to at least one of the end of the electric wire 11 and the tube main body 19 of the tube 13. Then, the tape 14 is wound around the tube main body 19 of the tube 13 over the entire length of the tube 13. Thus, after wrapping the tape 14 around the outer periphery of the linear tube 13 containing the electric wire 11, the both ends 19 a and 19 b of the cross section of the tube main body 19 are closely overlapped with each other over the entire length of the tube 13, Similar to the above-described embodiment, the portion 10a is appropriately bent.
　この図１５に示されたワイヤハーネス１０によれば、前述した実施形態の効果に加え、チューブ１３のチューブ本体１９の断面の両端部１９ａ，１９ｂを互いに重ねた状態に保つテープ１４を備えているので、適宜箇所１０ａを屈曲する際に、スリット２０を通してチューブ１３外に電線１１が飛び出ることを防止できる。したがって、ワイヤハーネス１０を確実に組み立てることができる。 According to the wire harness 10 shown in FIG. 15, in addition to the effects of the above-described embodiment, the tape 14 is provided to keep both end portions 19 a and 19 b of the cross section of the tube main body 19 of the tube 13 overlapped with each other. Therefore, it is possible to prevent the electric wire 11 from jumping out of the tube 13 through the slit 20 when the portion 10a is appropriately bent. Therefore, the wire harness 10 can be reliably assembled.
　なお、前述した実施形態は本発明の代表的な形態を示したに過ぎず、本発明は、実施形態に限定されるものではない。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。 It should be noted that the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.
