図１〜図４を用いて本発明の実施の形態に係るワイヤハーネス及びワイヤハーネス製造方法について説明する。   The wire harness and the wire harness manufacturing method according to the embodiment of the present invention will be described with reference to FIGS.

本実施の形態に係るワイヤハーネス１は、少なくとも一端側に屈曲部が設けられる複数の電線３と、屈曲部を外部に露出させ複数の電線３の外周を覆う外装部材５と、複数の電線３の外装部材５に覆われる部分に設けられ外装部材５の長さより長い余長部分を有する外装取付部７とを備えている。   A wire harness 1 according to the present embodiment includes a plurality of electric wires 3 provided with a bent portion at least on one end side, an exterior member 5 that exposes the outer periphery of the plurality of electric wires 3 by exposing the bent portions to the outside, and a plurality of electric wires 3. And an exterior mounting portion 7 having an extra length longer than the length of the exterior member 5.

そして、外装取付部７の両側で外装部材５の外部に露出する部分には、外装取付部７の余長部分を外装部材５の外部に配置させ外装取付部７の長さを外装部材５の長さと同等に保持する一対の固定部９，９が設けられている。   And in the part exposed to the exterior of the exterior member 5 in the both sides of the exterior mounting part 7, the extra length part of the exterior mounting part 7 is arrange | positioned outside the exterior member 5, and the length of the exterior mounting part 7 is set to the length of the exterior member 5. A pair of fixing portions 9 and 9 that are held to be equal to the length are provided.

また、本実施の形態に係るワイヤハーネス製造方法は、一対のフォーク治具１１，１１の間にフォーク治具１１，１１の間より長い余長部分を有して複数の電線３を配置させる第１工程と、ならし治具１３によって複数の電線３の余長部分を一対のフォーク治具１１，１１側に向けて移動させる第２工程と、一対のフォーク治具１１，１１の近傍にならし治具１３によって成形された複数の電線３の状態を保持する一対の固定部９，９を設ける第３工程と、一対の固定部９，９の間に位置する複数の電線３の外周に外装部材５を組付ける第４工程とを有する。   In addition, the wire harness manufacturing method according to the present embodiment has a long extra length portion between the pair of fork jigs 11 and 11 and the plurality of electric wires 3 are arranged. One step, a second step of moving the excess length portions of the plurality of electric wires 3 toward the pair of fork jigs 11, 11 by the leveling jig 13, and the vicinity of the pair of fork jigs 11, 11 A third step of providing a pair of fixing portions 9, 9 for holding the state of the plurality of electric wires 3 formed by the jig 13, and an outer periphery of the plurality of electric wires 3 positioned between the pair of fixing portions 9, 9. And a fourth step of assembling the exterior member 5.

図１〜図４に示すように、ワイヤハーネス１は、複数の電線３を束ねた電線束からなり、車両ボディ（不図示）に配索される。   As shown in FIGS. 1-4, the wire harness 1 consists of an electric wire bundle which bundled the some electric wire 3, and is wired by the vehicle body (not shown).

このワイヤハーネス１の複数の電線３は、車両ボディに配索された状態で、屈曲部（不図示）を介して屈曲され、車両に搭載された電源や機器などに電気的に接続される。   The plurality of electric wires 3 of the wire harness 1 are bent through a bent portion (not shown) while being routed in the vehicle body, and are electrically connected to a power source or equipment mounted on the vehicle.

このようなワイヤハーネス１では、複数の電線３の外周に、屈曲部を外部に露出するように、コルゲートチューブなどの長さ方向に沿ってスリット（不図示）が設けられた外装部材５が組付けられる。   In such a wire harness 1, an exterior member 5 provided with a slit (not shown) along the length direction of a corrugated tube or the like is formed on the outer periphery of the plurality of electric wires 3 so as to expose the bent portion to the outside. Attached.

この外装部材５によって覆われる部分である複数の電線３の外装取付部７は、外装部材５の長さより長い余長部分を有するように設定されている。   The exterior mounting portions 7 of the plurality of electric wires 3 that are portions covered by the exterior member 5 are set so as to have an extra length longer than the length of the exterior member 5.

ここで、ワイヤハーネス１では、複数の電線３の屈曲部が位置する部分において、内側の電線３と外側の電線３とでは曲率半径が異なる。   Here, in the wire harness 1, the radius of curvature is different between the inner electric wire 3 and the outer electric wire 3 in a portion where the bent portions of the plurality of electric wires 3 are located.

このため、例えば、複数の電線３を屈曲部を介して屈曲させて電源や機器などに接続する場合には、内側の電線３では電線３の長さを短く、外側の電線３では電線３の長さを長く設定する必要がある。   For this reason, for example, when a plurality of electric wires 3 are bent via a bent portion and connected to a power source or a device, the length of the electric wires 3 is short for the inner electric wires 3 and the electric wires 3 are shorter for the outer electric wires 3. It is necessary to set the length longer.

そこで、外装取付部７に外装部材５の長さより長い余長部分をもたせることにより、複数の電線３の長さを同一長さに設定しても、屈曲部における内側の電線３と外側の電線３との必要な長さの違いを余長部分によって吸収することができ、ワイヤハーネス１の組付けにおける複数の電線３にかかる負荷を吸収することができる。   Therefore, even if the length of the plurality of electric wires 3 is set to the same length by giving the outer attachment portion 7 an extra length longer than the length of the outer member 5, the inner electric wire 3 and the outer electric wire in the bent portion The required length difference from 3 can be absorbed by the extra length portion, and the load applied to the plurality of electric wires 3 in the assembly of the wire harness 1 can be absorbed.

しかしながら、外装取付部７は、その余長部分によって弛みが生じてしまうので、外装部材５の内径より複数の電線３の外径が張り出してしまい、外装取付部７に外装部材５を組付け難くしていた。   However, since the outer attachment portion 7 is slackened by the extra length, the outer diameters of the plurality of electric wires 3 protrude from the inner diameter of the outer member 5, and it is difficult to assemble the outer attachment member 5 to the outer attachment portion 7. Was.

この外装取付部７の弛みを無くすために、余長部分を外装取付部７の長さ方向の外側に移動するように、作業者が手で外装取付部７の外周をならしていたが、作業者によって出来栄えにバラツキが生じていた。   In order to eliminate the slackness of the exterior mounting portion 7, the operator manually leveled the outer periphery of the exterior mounting portion 7 so as to move the extra length portion to the outside in the length direction of the exterior mounting portion 7. There was a variation in workmanship by the workers.

また、外装取付部７をならしても、そのならされた外装取付部７の状態を保持しながら外装部材５を組付けなければならず、組付性が低下していた。   Moreover, even if the exterior mounting portion 7 is leveled, the exterior member 5 must be assembled while maintaining the state of the leveled exterior mounting portion 7, and the assemblability is reduced.

そこで、ワイヤハーネス１の外装取付部７は、ならし治具１３によってならされ、ならし治具１３によってならされた後、外装取付部７の長さ方向の両側に一対の固定部９，９が設けられる。   Therefore, the exterior mounting portion 7 of the wire harness 1 is leveled by the leveling jig 13, and after being leveled by the leveling jig 13, a pair of fixing portions 9 and 9 are provided on both sides of the length direction of the exterior mounting portion 7. Is provided.

ならし治具１３は、操作部１５と、ならし部１７と、変換部１９とを備えている。   The leveling jig 13 includes an operation unit 15, a leveling unit 17, and a conversion unit 19.

操作部１５は、治具台上に配置された一対のフォーク治具１１，１１間に配置された複数の電線３の外装取付部７の上方に上下方向に移動可能に配置され、作業者などによって下方に向けて押圧して操作される。   The operation unit 15 is disposed so as to be movable in the vertical direction above the exterior mounting portion 7 of the plurality of electric wires 3 disposed between the pair of fork jigs 11 disposed on the jig base. Is operated by pressing downward.

ならし部１７は、複数の電線３の外周を覆うようにコ字状に一対形成され、外装取付部７の長さ方向の両側にそれぞれ移動可能に配置され、複数の電線３と当接して移動により、外装取付部７の余長部分を外装取付部７の長さ方向の両側に向けて移動させ、外装取付部７の弛みをならす。   The leveling portions 17 are formed in a pair of U-shapes so as to cover the outer circumferences of the plurality of electric wires 3, are movably arranged on both sides in the length direction of the exterior mounting portion 7, and are in contact with the plurality of electric wires 3. By moving, the extra length portion of the exterior attachment portion 7 is moved toward both sides in the length direction of the exterior attachment portion 7, and the exterior attachment portion 7 is loosened.

変換部１９は、操作部１５と一体に設けられた支柱２１と、支柱２１に第１関節２３を介して回動可能に設けられた第１アーム２５及び第２アーム２７と、第１アーム２５に第２関節２９を介して回動可能に設けられた第３アーム３１と、第２アーム２７に第３関節３３を介して回動可能に設けられた第４アーム３５とを有し、一対のならし部１７，１７が第４関節３７及び第５関節３９を介して回動可能に第３アーム３１及び第４アーム３５と連結されている。   The conversion unit 19 includes a support column 21 provided integrally with the operation unit 15, a first arm 25 and a second arm 27 provided on the support column 21 via a first joint 23, and a first arm 25. A third arm 31 rotatably provided via the second joint 29 and a fourth arm 35 rotatably provided via the third joint 33 on the second arm 27, and The leveling portions 17 and 17 are connected to the third arm 31 and the fourth arm 35 through the fourth joint 37 and the fifth joint 39 so as to be rotatable.

このならし治具１３は、操作部１５の押圧操作により、変換部１９で押圧力が一対のならし部１７，１７の移動力に変換され、一対のならし部１７，１７によって外装取付部７の余長部分が長さ方向の両側に位置する一対のフォーク治具１１，１１側に向けて移動され、外装取付部７の弛みをならす。   In the leveling jig 13, the pressing force of the operation unit 15 is converted by the converting unit 19 into the moving force of the pair of leveling units 17, 17. The extra length portion 7 is moved toward the pair of fork jigs 11, 11 located on both sides in the length direction, and the exterior mounting portion 7 is loosened.

このようなならし治具１３によって外装取付部７の弛みをならすことにより、ワイヤハーネス１の外装取付部７の出来栄えにバラツキが生じることがなく、製品の均一化を図ることができる。   By smoothing the exterior mounting portion 7 with such a leveling jig 13, there is no variation in the quality of the exterior mounting portion 7 of the wire harness 1, and products can be made uniform.

このようにならし治具１３によってならされた外装取付部７の両側で外装部材５の外部に露出する部分には、一対の固定部９，９が設けられる。   A pair of fixing portions 9 and 9 are provided at portions exposed to the outside of the exterior member 5 on both sides of the exterior mounting portion 7 leveled by the leveling jig 13 in this way.

一対の固定部９，９は、外装取付部７の両側で外装部材５の外部に露出する部分に配置され、複数の電線３の外周にテープを巻き付けることによって形成される。   The pair of fixing portions 9 and 9 are disposed on both sides of the exterior mounting portion 7 and exposed to the outside of the exterior member 5, and are formed by winding a tape around the outer periphery of the plurality of electric wires 3.

この一対の固定部９，９は、外装取付部７をならし治具１３によってならした後、余長部分が外装部材５の外側に移動された外装取付部７の長さを外装部材５の長さと同等とするように、外装取付部７の状態を保持する。   The pair of fixing portions 9, 9, after the exterior mounting portion 7 is leveled by the leveling jig 13, the length of the exterior mounting portion 7 whose extra length portion has been moved to the outside of the exterior member 5 is the length of the exterior member 5. The state of the exterior mounting portion 7 is maintained so as to be equal to the length.

このように一対の固定部９，９を設けることにより、ならされた外装取付部７に弛みが生じることがなく、容易に外装取付部７に外装部材５を組付けることができ、組付性を向上することができる。   By providing the pair of fixing portions 9 and 9 in this manner, the exterior exterior mounting portion 7 is not loosened, and the exterior member 5 can be easily assembled to the exterior mounting portion 7. Can be improved.

このようなワイヤハーネス１の製造方法は、まず、治具板上に配置された一対のフォーク治具１１，１１間に、複数の電線３の余長部分を有する外装取付部７を配置する（第１工程）。   The manufacturing method of such a wire harness 1 arrange | positions the exterior mounting part 7 which has the extra length part of the some electric wire 3 between a pair of fork jigs 11 and 11 arrange | positioned on a jig board first ( First step).
