［外装体２０の製造工程］
　外装体２０及びワイヤーハーネス１１の製造工程の一例について説明する。
（１）押出工程
　図示しない押出成形装置を用いた押出成形により、合成樹脂を溶融状態とした後、金型を通した合成樹脂を冷却槽で冷却する。その後、切断機により所定の長さで切断する。これにより、図８に示すように、扁平な筒状の挿通部２１Ａ（外装体２０が形成される前の挿通部を２１Ａとして図示）を形成する。 [Manufacturing process of exterior body 20]
An example of the manufacturing process of the exterior body 20 and the wire harness 11 will be described.
(1) Extrusion process After the synthetic resin is melted by extrusion molding using an extrusion molding apparatus (not shown), the synthetic resin passed through a mold is cooled in a cooling tank. After that, it is cut to a predetermined length by a cutting machine. As a result, as shown in FIG. 8, a flat tubular insertion portion 21A (the insertion portion before the exterior body 20 is formed is shown as 21A) is formed.
（２）打ち抜き工程
　次に、図９に示すように、挿通部２１Ａにおける円弧状に湾曲した両側縁部をプレス機で前後方向に等間隔で打ち抜き、複数の切欠部２５Ａ，２６Ａを形成する。
（３）スリット形成工程
　次に、図示しない切断刃を駆動して、対向壁２３に対して、前後方向に等間隔で切断して上端部および下端部の各切欠部２５Ａ，２６Ａの間に複数のスリット２３Ａを形成する（図１０）。これにより、挿通部２１を有する外装体２０が形成される。なお、スリット２３Ａの形成は、これに限られず、例えば、図示しない長尺の板材（例えば合成樹脂板）を、切欠部２５Ａ，２６Ａが形成された挿通部２１Ａに挿入した後に、切断刃でスリット２３Ａを形成し、その後、長尺の板材を取り外してもよい。 (2) Punching Step Next, as shown in FIG. 9, both side edges curved in an arc shape in the insertion portion 21A are punched out at equal intervals in the front-rear direction with a press machine to form a plurality of cutout portions 25A and 26A.
(3) Slit forming step Next, a cutting blade (not shown) is driven to cut the facing wall 23 at equal intervals in the front-rear direction, and a plurality of slits are formed between the notches 25A and 26A at the upper end and the lower end. Slit 23A is formed (FIG. 10). As a result, the exterior body 20 having the insertion portion 21 is formed. The formation of the slit 23A is not limited to this, and for example, a long plate material (for example, a synthetic resin plate) (not shown) is inserted into the insertion portion 21A in which the notch portions 25A and 26A are formed, and then the slit is formed by the cutting blade. 23A may be formed and then the long plate may be removed.
（４）挿通工程
　次に、図１１に示すように、一端側が閉鎖されたキャップ１４を電線１２の端末部に取り付け、キャップ１４側を外装体２０の一端側の開口２０Ａから挿通し、外装体２０の他端側の開口２０Ｂから外部に導出する。そして、キャップ１４を取り外すことにより、ワイヤーハーネス１１（図４）が形成される。このワイヤーハーネス１１は、図７に示すように、外装体２０における挿通部２１の延びる方向（前後方向）に対して交差する第２方向について、左側（スリット２３Ａが形成された側と反対側）への曲げが許容され、右側（スリット２３Ａが形成された側）への曲げが規制される。ワイヤーハーネス１１の余長部１１Ａが余長収容部３０に収容されると、シート４０のスライドに応じて余長部１１Ａが巻回される。 (4) Insertion Step Next, as shown in FIG. 11, a cap 14 whose one end side is closed is attached to the terminal portion of the electric wire 12, and the cap 14 side is inserted through the opening 20A on one end side of the exterior body 20 to form the exterior body. It is led out from the opening 20B on the other end side of 20. Then, by removing the cap 14, the wire harness 11 (FIG. 4) is formed. As shown in FIG. 7, the wire harness 11 is on the left side (the side opposite to the side on which the slit 23A is formed) in the second direction intersecting the extending direction (front-back direction) of the insertion portion 21 in the exterior body 20. Bending to the right side (the side where the slit 23A is formed) is restricted. When the extra length portion 11A of the wire harness 11 is accommodated in the extra length accommodating portion 30, the extra length portion 11A is wound according to the slide of the sheet 40.
　本実施形態によれば、以下の作用、効果を奏する。
　外装体２０は、少なくとも１つの電線１２を挿通可能であって、前後方向に沿って延びるとともに扁平な筒状をなす挿通部２１を備え、挿通部２１は、互いに対向配置された一対の対向壁２３，２４と一対の対向壁２３，２４を一体に連結する一対の連結壁２５，２６とを有し、一対の対向壁２３，２４のうち一方の対向壁２３には、上下方向に延びる複数のスリット２３Ａが形成されている。
　上記実施形態によれば、扁平な形状の挿通部２１により、例えばコルゲートチューブを用いる場合と比較して、電線１２と外装体２０との間の隙間を小さくすることができ、ワイヤーハーネス１１を小型化することが可能になる。 According to this embodiment, the following actions and effects are exhibited.
The exterior body 20 includes an insertion portion 21 capable of inserting at least one electric wire 12 and extending in the front-rear direction and forming a flat tubular shape, and the insertion portion 21 is a pair of facing walls arranged to face each other. It has a pair of connecting walls 25 and 26 that integrally connect the pair of facing walls 23 and 24 with the 23, 24, and one of the pair of facing walls 23 and 24 has a plurality of connecting walls 23 extending in the vertical direction. Slit 23A is formed.
According to the above embodiment, the flat-shaped insertion portion 21 makes it possible to reduce the gap between the electric wire 12 and the exterior body 20 as compared with the case where, for example, a corrugated tube is used, and the wire harness 11 can be made smaller. It becomes possible to change.
　また、挿通部２１は、一対の連結壁２５，２６の一部を切り欠いた複数の切欠部２５Ａ，２６Ａを備え、複数の切欠部２５Ａ，２６Ａのそれぞれは、複数のスリット２３Ａのそれぞれの端部に連なっている。
　このようにすれば、外装体２０におけるスリット２３Ａの端部の近傍の破れを抑制することができる。 Further, the insertion portion 21 includes a plurality of cutout portions 25A, 26A obtained by cutting out a part of the pair of connecting walls 25, 26, and each of the plurality of cutout portions 25A, 26A is an end of each of the plurality of slits 23A. It is connected to the department.
By doing so, it is possible to suppress tearing in the vicinity of the end portion of the slit 23A in the exterior body 20.
　また、一対の連結壁２５，２６は、外方側に膨らむように湾曲している。
　このようにすれば、一対の連結壁２５，２６が電線１２の外周形状に応じた形状となるため、連結壁２５，２６と電線１２との間の隙間を小さくすることができる。 Further, the pair of connecting walls 25 and 26 are curved so as to bulge outward.
By doing so, since the pair of connecting walls 25 and 26 have a shape corresponding to the outer peripheral shape of the electric wire 12, the gap between the connecting walls 25 and 26 and the electric wire 12 can be reduced.
　本実施形態にかかるワイヤーハーネス１１は、複数の電線１２を備え、複数の電線１２のそれぞれは、前後方向に沿って延びる１つの芯線１２Ａと、芯線１２Ａの外周を覆う絶縁性の合成樹脂からなる絶縁被覆１２Ｂと、を有する。 The wire harness 11 according to the present embodiment includes a plurality of electric wires 12, each of the plurality of electric wires 12 is made of one core wire 12A extending in the front-rear direction and an insulating synthetic resin covering the outer periphery of the core wire 12A. It has an insulating coating 12B and.
　また、ワイヤーハーネス配索装置１０は、ワイヤーハーネス１１と、ワイヤーハーネス１１が挿通されるレール１５と、スライド対象物の移動に伴ってスライドし、ワイヤーハーネス１１が固定されるスライダ１７と、レール１５外に導出されたワイヤーハーネス１１の余長部１１Ａを収容する余長収容部３０と、を備える。
　このようにすれば、レール１５内のワイヤーハーネス１１を小型化することができるため、レール１５内の空きスペースを有効に利用したり、レール１５を小型化することが可能になる。 Further, the wire harness routing device 10 slides along with the wire harness 11, the rail 15 through which the wire harness 11 is inserted, the slider 17 to which the wire harness 11 is fixed, and the rail 15. The extra length accommodating portion 30 for accommodating the extra length portion 11A of the wire harness 11 led out to the outside is provided.
In this way, the wire harness 11 in the rail 15 can be miniaturized, so that the empty space in the rail 15 can be effectively used and the rail 15 can be miniaturized.
＜実施形態２＞
　次に、本開示の実施形態２を図１２から図１３を参照しつつ説明する。本実施形態にかかるワイヤーハーネス５０においては、１つの挿通部２１の内部に、１つのフレキシブルフラットケーブル５２（扁平電線の一例）が総通されている。フレキシブルフラットケーブル５２は、前後方向（第１方向の一例）に延びるとともに、左右方向（第２方向の一例）について扁平な形状をなしている。 <Embodiment 2>
Next, Embodiment 2 of the present disclosure will be described with reference to FIGS. 12 to 13. In the wire harness 50 according to the present embodiment, one flexible flat cable 52 (an example of a flat electric wire) is generally passed through one insertion portion 21. The flexible flat cable 52 extends in the front-rear direction (an example of the first direction) and has a flat shape in the left-right direction (an example of the second direction).
　図１３に示されるように、フレキシブルフラットケーブル５２は、複数（本実施形態では６つ）の芯線５２Ａが、上下方向（第３方向の一例）について間隔を空けて並んで配されている。各芯線５２Ａの断面は左右方向について扁平な四角形状をなしている。各芯線５２Ａの断面は同形同大に形成されている。複数の芯線５２Ａは絶縁性の合成樹脂からなる絶縁被覆５２Ｂに覆われている。絶縁被覆５２Ｂは、隣り合う芯線５２Ａの間に介在している。各芯線５２Ａは絶縁被覆５２Ｂにより互いに電気的に絶縁されている。詳細には図示しないが、２枚の絶縁性のシートが複数の芯線５２Ａを挟んだ状態で接着されることにより、絶縁被覆５２Ｂが形成されてもよい。 As shown in FIG. 13, in the flexible flat cable 52, a plurality of (six in this embodiment) core wires 52A are arranged side by side at intervals in the vertical direction (an example of the third direction). The cross section of each core wire 52A has a flat quadrangular shape in the left-right direction. The cross section of each core wire 52A is formed to have the same shape and size. The plurality of core wires 52A are covered with an insulating coating 52B made of an insulating synthetic resin. The insulating coating 52B is interposed between the adjacent core wires 52A. The core wires 52A are electrically insulated from each other by the insulating coating 52B. Although not shown in detail, the insulating coating 52B may be formed by adhering two insulating sheets in a state of sandwiching a plurality of core wires 52A.
　フレキシブルフラットケーブル５２の上下方向の高さ寸法は、挿通部２１の内面の上下方向の差し渡し寸法よりも小さい。また、フレキシブルフラットケーブル５２の左右方向の厚さ寸法は、挿通部２１の内面の左右方向の差し渡し寸法よりも小さい。これにより、フレキシブルフラットケーブル５２は、挿通部２１の内部空間において自由に曲がることができるようになっている。 The vertical height dimension of the flexible flat cable 52 is smaller than the vertical extension dimension of the inner surface of the insertion portion 21. Further, the thickness dimension of the flexible flat cable 52 in the left-right direction is smaller than the width dimension of the inner surface of the insertion portion 21 in the left-right direction. As a result, the flexible flat cable 52 can be freely bent in the internal space of the insertion portion 21.
　上記以外の構成については実施形態１と同様なので、重複する部材には同一の符号を付し、重複する説明を省略する。 Since the configurations other than the above are the same as those in the first embodiment, the same reference numerals are given to the overlapping members, and the overlapping description will be omitted.
　本実施形態にかかるワイヤーハーネス５０は、導電部材として、前後方向に沿って延びるとともに上下方向に間隔を空けて並ぶ複数の芯線５２Ａと、複数の芯線５２Ａの外周を一括して覆うとともに複数の芯線５２Ａの間に介在する絶縁性の合成樹脂からなる絶縁被覆５２Ｂと、を有する扁平電線を備える。 As a conductive member, the wire harness 50 according to the present embodiment collectively covers a plurality of core wires 52A extending along the front-rear direction and arranged at intervals in the vertical direction, and a plurality of core wires 52A. A flat electric wire having an insulating coating 52B made of an insulating synthetic resin interposed between the 52A and 52A is provided.
　フレキシブルフラットケーブル５２は電線１２に比べて左右方向の厚さ寸法を小さくできる。このため、ワイヤーハーネス配索装置１０において、余長収容部３０内に収容される余長部１１Ａを小型化できる。この結果、余長収容部３０も小型化ができるので、全体としてワイヤーハーネス配索装置１０を小型化できる。 The flexible flat cable 52 can have a smaller thickness in the left-right direction than the electric wire 12. Therefore, in the wire harness routing device 10, the extra length portion 11A accommodated in the extra length accommodating portion 30 can be miniaturized. As a result, the extra length accommodating portion 30 can also be miniaturized, so that the wire harness routing device 10 can be miniaturized as a whole.
　一方、フレキシブルフラットケーブル５２は電線１２に比べて剛性が低いので、余長収容部３０内に収容する際に座屈しやすい。フレキシブルフラットケーブル５２が座屈すると、余長収容部３０内にそれ以上押し込むことが困難になるおそれがある。 On the other hand, since the flexible flat cable 52 has a lower rigidity than the electric wire 12, it is easy to buckle when it is accommodated in the extra length accommodating portion 30. If the flexible flat cable 52 buckles, it may be difficult to push it further into the extra length accommodating portion 30.
　そこで、本開示においては、フレキシブルフラットケーブル５２は外装体２０の挿通部２１内に挿通される構成とした。これによりフレキシブルフラットケーブル５２が外装体２０によって補強されるので、余長収容部３０内に容易に押し込むことができる。 Therefore, in the present disclosure, the flexible flat cable 52 is configured to be inserted into the insertion portion 21 of the exterior body 20. As a result, the flexible flat cable 52 is reinforced by the exterior body 20, so that the flexible flat cable 52 can be easily pushed into the extra length accommodating portion 30.
　また、本実施形態によれば、複数の芯線５２Ａのそれぞれは、左右方向について扁平な形状をなしている。 Further, according to the present embodiment, each of the plurality of core wires 52A has a flat shape in the left-right direction.
　これにより、芯線５２Ａの断面が円形状をなしている場合に比べて、フレキシブルフラットケーブル５２の左右方向の厚さ寸法を小さくすることができる。これにより、余長収容部３０の大きさをさらに小型化できるので、ワイヤーハーネス配索装置１０をさらに小型化できる。 As a result, the thickness dimension of the flexible flat cable 52 in the left-right direction can be reduced as compared with the case where the cross section of the core wire 52A has a circular shape. As a result, the size of the extra length accommodating portion 30 can be further reduced, so that the wire harness routing device 10 can be further miniaturized.
＜実施形態３＞
　次に、本開示の実施形態３について、図１４から図１５を参照しつつ説明する。本実施形態にかかるワイヤーハーネス６０おいては、フレキシブルフラットケーブル６２の芯線６２Ａの断面が円形状をなしている。各芯線６２Ａは絶縁被覆６２Ｂにより包囲されている。上記以外の構成については実施形態２と同様なので、同一部材については同一符号を付し、重複する説明を省略する。 <Embodiment 3>
Next, the third embodiment of the present disclosure will be described with reference to FIGS. 14 to 15. In the wire harness 60 according to the present embodiment, the cross section of the core wire 62A of the flexible flat cable 62 has a circular shape. Each core wire 62A is surrounded by an insulating coating 62B. Since the configurations other than the above are the same as those in the second embodiment, the same members are designated by the same reference numerals, and duplicate description will be omitted.
＜実施形態４＞
　次に、本開示の実施形態４について、図１６から図１７を参照しつつ説明する。本実施形態にかかるワイヤーハーネス７０おいては、外装体２０の挿通部２１内には、１つの扁平電線７２が挿通されるようになっている。 <Embodiment 4>
Next, the fourth embodiment of the present disclosure will be described with reference to FIGS. 16 to 17. In the wire harness 70 according to the present embodiment, one flat electric wire 72 is inserted into the insertion portion 21 of the exterior body 20.
　図１７に示されるように、扁平電線７２は、複数（本実施形態では７つ）の芯線７２Ａが、上下方向について間隔を空けて並んで配されている。各芯線７２Ａの断面は円形状をなしている。各芯線７２Ａの断面は同形同大に形成されている。複数の芯線７２Ａは絶縁性の合成樹脂からなる絶縁被覆７２Ｂに覆われている。絶縁被覆７２Ｂは、隣り合う芯線７２Ａの間に介在している。各芯線７２Ａは絶縁被覆７２Ｂにより互いに電気的に絶縁されている。 As shown in FIG. 17, in the flat electric wire 72, a plurality of core wires 72A (seven in the present embodiment) are arranged side by side at intervals in the vertical direction. The cross section of each core wire 72A has a circular shape. The cross section of each core wire 72A is formed to have the same shape and size. The plurality of core wires 72A are covered with an insulating coating 72B made of an insulating synthetic resin. The insulating coating 72B is interposed between the adjacent core wires 72A. The core wires 72A are electrically insulated from each other by the insulating coating 72B.
　絶縁被覆７２Ｂは、芯線７２Ａの外形状に倣った形状に左右方向に突出するとともに前後方向に延びる曲面部７３と、各芯線７２Ａの間に配されて、曲面部７３同士を連結する連結７４部と、を有する。連結部７４は、左右方向について曲面部７３よりも薄く形成されている。本実施形態にかかる扁平電線７２は、断面が円形状をなす電線１２が、絶縁性の合成樹脂によって連結されたような形状をなしている。 The insulating coating 72B is arranged between a curved surface portion 73 that projects in the left-right direction and extends in the front-rear direction in a shape that follows the outer shape of the core wire 72A, and a connecting 74 portion that connects the curved surface portions 73 to each other. And have. The connecting portion 74 is formed thinner than the curved surface portion 73 in the left-right direction. The flat electric wire 72 according to the present embodiment has a shape in which an electric wire 12 having a circular cross section is connected by an insulating synthetic resin.
　上記以外の構成については、実施形態２と同様なので、同一部材については同一の符号を付し、重複する説明を省略する。 Since the configurations other than the above are the same as those in the second embodiment, the same members are designated by the same reference numerals, and duplicate description will be omitted.
　本実施形態によれば、扁平電線７２の端末において連結部７４を引き裂くことにより、複数の電線１２に分けることができる。このようにして分けられた各電線１２について、通常の電線１２と同様に、絶縁被覆１２Ｂを剥がして端子（図示せず）を接続することができる。このように、扁平電線７２の端末処理を、通常の電線１２と同様に行うことができるので、ワイヤーハーネス７０の製造工程が煩雑になることを抑制できる。 According to this embodiment, the flat electric wire 72 can be divided into a plurality of electric wires 12 by tearing the connecting portion 74 at the terminal. For each electric wire 12 separated in this way, the insulating coating 12B can be peeled off and terminals (not shown) can be connected in the same manner as the normal electric wire 12. In this way, since the terminal processing of the flat electric wire 72 can be performed in the same manner as that of the normal electric wire 12, it is possible to prevent the manufacturing process of the wire harness 70 from becoming complicated.

The two flexible flat cables 52 have the same shape and size.
　上記以外の構成については、実施形態２と同様なので、同一部材については同一の符号を付し、重複する説明を省略する。 Since the configurations other than the above are the same as those in the second embodiment, the same members are designated by the same reference numerals, and duplicate description will be omitted.
