しかしながら、上記従来の特許文献１，２（図６）の布線治具６１にあっては、図７（平面図）にＵフォーク６９に各一般電線６６を布線した状態を示す如く、各電線６６が曲がり癖によって必ずしも真直に配索されるわけではないので、中央の特定電線６４が周囲の各電線６６の曲がり癖の影響を受けて、曲がって配索され、特定電線６４の長さが規定よりも短縮されてしまうといった懸念があった。   However, in the wiring jig 61 of the above-mentioned conventional patent documents 1 and 2 (FIG. 6), as shown in FIG. 7 (plan view), each general electric wire 66 is wired to the U fork 69. Since the electric wire 66 is not necessarily routed straight due to the bending hook, the specific wire 64 at the center is bent and routed under the influence of the bending hook of each surrounding electric wire 66, and the length of the specific electric wire 64 is increased. There was a concern that would be shortened from the regulation.

FIG. 1A is a plan view of the wiring jig, FIG. 1B is a front view with a part in the same section, and FIG. 1C is an enlarged view of the main part of FIG.

この布線治具１は、図１（ｂ）の如くＵフォーク状の布線治具本体２と、布線治具本体２のＵ字状の電線受け部３の底部４に形成された特殊線配索溝５と、特殊線配索溝５を覆ってＵ字状の電線受け部３内の電線挿通空間６から区画分離する薄板ばね状の開閉自在な区画板７と、図１（ａ）の如く特殊線配索溝５から特殊線（図示せず）の配索（分岐）方向に突出した外向き湾曲状の左右一対の特殊線ガイド板４３とを備えるものである。   As shown in FIG. 1B, the wiring jig 1 is a U-fork-shaped wiring jig body 2 and a special part formed on the bottom 4 of the U-shaped wire receiving portion 3 of the wiring jig body 2. The wire routing groove 5, a thin spring-like openable and closable partition plate 7 that covers and separates the special wire routing groove 5 from the wire insertion space 6 in the U-shaped wire receiving portion 3, and FIG. And a pair of special line guide plates 43 that are curved outward and project from the special line routing groove 5 in the direction of the special line (not shown).

布線治具本体２は既存のＵフォークであり、金属製の上半のＵ字状の電線受け部３と下半の垂直な支柱９と、支柱９の中間部に固定された鍔部１０とを備え、支柱９は、鍔部１０よりも下側において雄ねじ部１１を有し、水平な布線板１２の孔部１２ａに環状スペーサ１３を介して裏側のワッシャ１４とナット１５で締付固定される。布線板１２と支柱９とは直交しており、布線板１２を傾斜させて配置した場合は支柱９も斜めに傾倒する。   The wiring jig body 2 is an existing U fork, which is a metal upper half U-shaped wire receiving portion 3, a lower half vertical column 9, and a flange 10 fixed to the middle portion of the column 9. The support column 9 has a male threaded portion 11 below the flange portion 10 and is fastened to a hole portion 12a of a horizontal wiring board 12 with a washer 14 and a nut 15 on the back side via an annular spacer 13. Fixed. The wiring board 12 and the support column 9 are orthogonal to each other, and when the wiring board 12 is arranged to be inclined, the support column 9 also tilts obliquely.

上半の電線受け部３は、左右一対の杆状の垂直な真直部３ａと、左右の真直部３ａを連結した底部４側の湾曲部３ｂとで成り、湾曲部３ｂの中央すなわち支柱９の延長軸線上の底部４に特殊線配索溝５が上から下に掘り下げて、且つ前後（電線配索方向）に貫通して設けられている。   The upper half of the wire receiving portion 3 is composed of a pair of left and right hook-shaped vertical straight portions 3a and a curved portion 3b on the bottom 4 side connecting the right and left straight portions 3a. A special wire routing groove 5 is dug down from the top to the bottom 4 on the extension axis, and is provided to penetrate in the front-rear direction (wire routing direction).

本例の特殊線配索溝５は、図１（ｃ）の水平な底面５ａと垂直な左右の側面５ｂとで囲まれて凹字状に構成され、挿通させる特殊線の外径と同等ないしそれ以上の深さを有している。水平な底面５ａを湾曲状に形成することも可能である。本例の電線受け部３の真直部３ａは図１（ａ）の如く横断面長円形であり、湾曲部３ｂも同様であるが、これらを断面円形や矩形状（エッジは除去する）とすることも可能である。   The special wire routing groove 5 of this example is formed in a concave shape surrounded by the horizontal bottom surface 5a and the right and left side surfaces 5b in FIG. 1 (c), and is equivalent to the outer diameter of the special line to be inserted. It has a greater depth. It is also possible to form the horizontal bottom surface 5a in a curved shape. The straight portion 3a of the wire receiving portion 3 of this example has an elliptical cross section as shown in FIG. 1A, and the curved portion 3b has the same shape, but has a circular cross section and a rectangular shape (edges are removed). It is also possible.

特殊線配索溝５の上側とその左右の近傍で湾曲部３ｂの上面に沿って弾性の区画板７が下向き湾曲状に配設されている。区画板７の基端部７ａ（図１（ｃ））に前後一対のＬ字板状のブラケット１６が下向きに一体に設けられ、各ブラケット１６の各底板１６ａが重なった状態でビス１７で右側の湾曲部３ｂの下面に締付固定されている。ブラケット１６は前側又は後側の一方のみでもよい。   An elastic partition plate 7 is arranged in a downward curved shape along the upper surface of the curved portion 3b on the upper side of the special line routing groove 5 and in the vicinity of the left and right sides thereof. A pair of front and rear L-shaped brackets 16 are integrally provided downward on the base end portion 7a (FIG. 1C) of the partition plate 7 so that the bottom plate 16a of each bracket 16 is overlapped with the screw 17 on the right side. It is fastened and fixed to the lower surface of the curved portion 3b. The bracket 16 may be only one of the front side or the rear side.

ブラケット１６から特殊線配索溝５の右端５ｂまでの間に区画板７の基部側部分７ｂが撓み自在に配置され、区画板７の長手方向中間部分７ｃが特殊線配索溝５の上に湾曲状に配置され、区画板７の先端部（自由端部）７ｄが左側の湾曲部３ｂの上面に接し、先端部７ｄの先端部分は上向きに屈曲されて開き操作部７ｄ’となっている。   Between the bracket 16 and the right end 5 b of the special line routing groove 5, the base side portion 7 b of the partition plate 7 is disposed so as to be freely bent, and the longitudinal intermediate portion 7 c of the partition plate 7 is placed on the special line routing groove 5. Arranged in a curved shape, the distal end portion (free end portion) 7d of the partition plate 7 is in contact with the upper surface of the left curved portion 3b, and the distal end portion of the distal end portion 7d is bent upward to form an opening operation portion 7d ′. .

ハーネス配索作業者が開き操作部７ｄ’を図１（ｃ）の矢印の如く手指等で持ち上げて、ブラケット１６を支点に区画板７を上向きに開いた（撓ませた）状態で、特殊線を特殊線配索溝５内に水平に配索し、区画板７から手指等を離すことで、区画板７が自身の弾性で復元して特殊線配索溝５を自動的に閉じる。特殊線は湾曲部３ｂの上面に沿って下向きにスライドさせつつ特殊線配索溝５内にスムーズに挿入させることができる。   The harness wiring operator lifts the opening operation portion 7d 'with fingers or the like as shown by the arrow in FIG. 1C, and opens the partition plate 7 upward (flexed) with the bracket 16 as a fulcrum. Is routed horizontally in the special line routing groove 5 and the fingers are released from the partition plate 7, so that the partition plate 7 is restored by its own elasticity and the special line routing groove 5 is automatically closed. The special line can be smoothly inserted into the special line routing groove 5 while sliding downward along the upper surface of the curved portion 3b.

区画板７の材質は薄板金属材であることが好ましい。特殊線は、前述の如く同軸電線やツイスト電線やチューブ（ホース）や光ファイバやトランクケーブル等のワイヤロープ等といった類のものを適用可能である。   The material of the partition plate 7 is preferably a thin metal material. As the special wire, a coaxial wire, a twisted wire, a tube (hose), a wire rope such as an optical fiber or a trunk cable, etc. can be applied as described above.

閉じた区画板７の上から電線受け部３内に図１（ｃ）の鎖線の如く複数本の一般電線８ａが一本ずつ配索される。特殊線配索溝５内の特殊線の上側に一般電線群８が位置し、特殊線の中心と電線群８の中心とはほぼ鉛直方向の同一線上に位置する（電線群８の真下に特殊線が位置する）。その状態でテープ巻きやバンド締め等で電線群８と特殊線が結束され、作業者が布線治具１から電線群８を持ち上げることで、特殊線が区画板７を上向きに撓ませつつ押しのけて電線群８と一体に布線治具１から取り出される。区画板７は弾性的に下向きに復元して特殊線配索溝５を閉じる。   A plurality of general electric wires 8a are routed one by one as shown by chain lines in FIG. The general wire group 8 is located above the special line in the special wire routing groove 5, and the center of the special line and the center of the wire group 8 are located on the same vertical line (the special wire is directly below the wire group 8. Line is located). In this state, the electric wire group 8 and the special wire are bundled by tape winding or band tightening, and the operator lifts the electric wire group 8 from the wiring jig 1 so that the special wire is pushed while bending the partition plate 7 upward. Then, it is taken out from the wiring jig 1 together with the electric wire group 8. The partition plate 7 is elastically restored downward to close the special wire routing groove 5.

布線板１２上における電線群８の屈曲方向すなわち布線板上の各布線治具１への配索分岐方向は水平方向であり、特殊線は電線群８の屈曲方向に対して９０°方向（鉛直方向）下向きに位置する。電線群８には係止クリップやグロメットやプロテクタ等といった部品が装着されるが、少なくとも電線群８と特殊線とでワイヤハーネス（組電線）が構成される。   The bending direction of the electric wire group 8 on the wiring board 12, that is, the wiring and branching direction to each wiring jig 1 on the wiring board is a horizontal direction, and the special wire is 90 ° with respect to the bending direction of the electric wire group 8. It is located downward in the direction (vertical direction). Parts such as a locking clip, a grommet, a protector, and the like are attached to the electric wire group 8, and a wire harness (assembled electric wire) is configured by at least the electric wire group 8 and a special wire.

特殊線を電線群８の内部に組み込まないことで、各電線８ａの曲がり癖の影響を受けることなく、特殊線が真直に正確な長さで配索される。特殊線を電線群８の外周に沿わせただけでは、各電線８ａの曲がり癖の影響をうけやすいが、区画板７で電線群とは区画することで、曲がり癖の影響が確実に防止される。また、特殊線を常に同一箇所（電線群８の下側）に配索することで、特殊線を分岐した際の分岐長さが常に一定に安定して保たれる。   By not incorporating the special wires inside the electric wire group 8, the special wires are routed with a straight and accurate length without being affected by the bending of each electric wire 8a. It is easy to be affected by the bending of each electric wire 8a just by placing the special wire along the outer periphery of the electric wire group 8. However, by dividing the electric wire group by the partition plate 7, the influence of the bending flaw is surely prevented. The In addition, by always routing the special line to the same location (below the electric wire group 8), the branch length when the special line is branched is always kept constant and stable.

また、特殊線配索溝５から前後方向に左右一対の特殊線ガイド板（ガイド部）４３が水平に突出して設けられ、特殊線配索溝５の左右の内端面５ｂが各特殊線ガイド板４３の湾曲状の内面と同一面に位置し、又は各特殊線ガイド板４３の中央の真直な内面が特殊線配索溝５の左右の内端面５ｂを成し（兼ね）ている。   Further, a pair of left and right special wire guide plates (guide portions) 43 are provided so as to protrude horizontally from the special wire routing groove 5 in the front-rear direction, and the left and right inner end surfaces 5b of the special line routing groove 5 are provided as special wire guide plates. 43 is located on the same plane as the curved inner surface, or the straight inner surface at the center of each special wire guide plate 43 forms (also serves as) the left and right inner end surfaces 5 b of the special wire routing groove 5.

例えば、金属製の左右一対の特殊線ガイド板４３の中央の真直部分（符号５ｂで代用）が特殊線配索溝５の左右端に嵌め込まれて、ハンダ付けや接着やねじ止め等で固定されている。あるいは前後左右の四つの湾曲状の特殊線ガイド板４３の基端が電線受け部３の底部４の前後の端面にハンダ付け等で固定されている。あるいは、特殊線ガイド板４３が特殊線配索溝５の底面５ａに沿う底板を一体に有し、底板が底面５ａにハンダ付け等で固定され、底板に続く左右の特殊線ガイド板本体４３が特殊線配索溝５から前後に湾曲状に突出している（この構造が電線受け部３への組付性に優れる）。   For example, the center straight portion of the pair of left and right special wire guide plates 43 (in place of reference numeral 5b) is fitted into the left and right ends of the special wire routing groove 5 and fixed by soldering, bonding, screwing, or the like. ing. Alternatively, the base ends of the four curved special wire guide plates 43 on the front, rear, left and right are fixed to the front and rear end surfaces of the bottom portion 4 of the wire receiving portion 3 by soldering or the like. Alternatively, the special line guide plate 43 integrally has a bottom plate along the bottom surface 5a of the special line routing groove 5, and the bottom plate is fixed to the bottom surface 5a by soldering or the like. It protrudes from the special wire routing groove 5 back and forth in a curved shape (this structure is excellent in assembling to the wire receiving portion 3).

何れにおいても、特殊線ガイド板４３は前方と後方とにそれぞれ突出した１／４円状の湾曲部分４３ａ（図１（ａ））を有している。各湾曲部分４３ａの先端４３ｂは電線受け部３の垂直な杆部３ａの外径よりも外側に少し長く突出している。本例の特殊線ガイド板４３は特殊線配索溝５の深さと同等の幅狭の縦幅寸法を有しているが、特殊線ガイド板４３を下方に延長して幅広の縦幅寸法のものとすることも可能である。   In any case, the special wire guide plate 43 has a ¼-circular curved portion 43a (FIG. 1A) protruding forward and rearward. The distal end 43b of each curved portion 43a protrudes slightly longer outside the outer diameter of the vertical flange 3a of the wire receiving portion 3. The special line guide plate 43 of this example has a narrow vertical width dimension equivalent to the depth of the special line routing groove 5, but the special line guide plate 43 is extended downward to have a wide vertical width dimension. It is also possible.

また、左右の特殊線ガイド板４３を連結する略扇状の水平な底壁（図示せず）を設けて、底壁で特殊線を支持しつつ特殊線ガイド板４３に沿って屈曲させることも可能である。また、特殊線受け部３の前側又は後側のみに特殊線ガイド板４３（左右一対の湾曲部分４３ａ）を設けることも可能であり、特殊線受け部３の右側又は左側のみに特殊線ガイド板４３（前後一対の湾曲部分４３ａ）を設けることも可能である。   It is also possible to provide a substantially fan-shaped horizontal bottom wall (not shown) for connecting the left and right special line guide plates 43 and bend along the special line guide plate 43 while supporting the special lines on the bottom wall. It is. It is also possible to provide a special wire guide plate 43 (a pair of left and right curved portions 43a) only on the front side or the rear side of the special wire receiving portion 3, and the special wire guide plate is provided only on the right side or the left side of the special wire receiving portion 3. It is also possible to provide 43 (a pair of front and rear curved portions 43a).

特殊線配索溝５内に真直に配索された特殊線は特殊線ガイド板４３の湾曲部４３ａに接触することはないが、布線治具１において特殊線を分岐する場合に、特殊線が特殊線ガイド板４３の湾曲部４３ａの内面に沿って大きな半径で滑らかに屈曲されて、特殊線の曲げ応力が低く抑えられる。   The special line routed straight in the special line routing groove 5 does not contact the curved portion 43a of the special line guide plate 43. However, when the special line is branched in the wiring jig 1, Is smoothly bent with a large radius along the inner surface of the curved portion 43a of the special line guide plate 43, and the bending stress of the special line is kept low.

これにより、特殊線としての例えば同軸線では導電性の編組線の偏りが防止されて、電磁シールドが良好に行われ、ツイスト線では絶縁被覆等の傷みが防止されて、ノイズ防止が確実に行われ、光ケーブルでは断線や変形が防止されて、光通信が正確に行われ、チューブでは内径部の狭窄が防止されて、気体や液体の流通が良好に行われ、ワイヤロープでは摩擦抵抗の増大が防止されて、車両のトランク等の開閉がスムーズに行われる。   As a result, for example, a coaxial wire as a special wire prevents the conductive braided wire from being biased, and the electromagnetic shield is satisfactorily performed.A twisted wire prevents damage to the insulation coating, etc., and noise prevention is reliably performed. In optical cables, disconnection and deformation are prevented, optical communication is performed accurately, narrowing of the inner diameter portion is prevented in tubes, gas and liquid flow is favorably performed, and friction resistance is increased in wire ropes. Thus, the trunk of the vehicle is opened and closed smoothly.

なお、図１の実施形態のＵフォーク状の布線治具本体１に代えて、Ｕ字状の電線受け部３を左右一対連結したＷ字状の電線受け部（図示せず）を有するＷフォーク状の布線治具本体を用い、この左及び／又は右のＵ字状の電線受け部３に特殊線配索溝５と区画板７とを設けることも可能である。また、Ｕ字状の電線受け部３に代えて、環状でヒンジを支点に開閉自在な上下分割式の電線受け部（図示せず）を用いることも可能である。   In place of the U-fork-shaped wiring jig body 1 of the embodiment of FIG. 1, a W-shaped wire receiving portion (not shown) in which a pair of U-shaped wire receiving portions 3 are connected to the left and right is provided. It is also possible to use the fork-shaped wiring jig body and provide the special wire routing groove 5 and the partition plate 7 in the left and / or right U-shaped wire receiving portion 3. Further, instead of the U-shaped electric wire receiving portion 3, it is also possible to use an upper and lower divided electric wire receiving portion (not shown) that can be opened and closed with a hinge as a fulcrum.

また、図１の実施形態において、特殊線ガイド部として、特殊線ガイド板４３の厚みを増して、内側のみに湾曲面を有する（外側は真直でもよい）特殊線ガイドブロック等を用いることも可能である。   Further, in the embodiment of FIG. 1, as the special line guide portion, it is possible to increase the thickness of the special line guide plate 43 and use a special line guide block having a curved surface only on the inner side (the outer side may be straight). It is.

図２（ａ）（ｂ）は、上記布線治具１を用いたハーネス配索構造の一形態を示すものである。   2A and 2B show an embodiment of a harness wiring structure using the wiring jig 1. FIG.

図２（ａ）の例の如く複数本の電線８ａ（電線群８）をＴ字状に配索する場合は、布線治具１は例えば電線群８の交差部８ｂに斜めに配置され、布線治具１の電線受け部３の中央を通って特殊線１９が９０°方向に屈曲して配索されて、電線受け部３の前後でテープ巻き２０等で結束される。   When arranging a plurality of electric wires 8a (electric wire group 8) in a T-shape as in the example of FIG. 2A, the wiring jig 1 is disposed obliquely at, for example, the intersecting portion 8b of the electric wire group 8, The special wire 19 is bent and routed in the 90 ° direction through the center of the wire receiving portion 3 of the wiring jig 1, and is bound by tape winding 20 or the like before and after the wire receiving portion 3.

図２（ｂ）の如く、本例において特殊線１９は電線群８の上下に各一本ずつ配索されている。下側の特殊線１９は電線受け部３の特殊線配索溝５（図１）に布線され、上側の特殊線１９は例えば電線群８を配索し終えた後に電線群８の頂部に沿って配索するか、あるいは後述の布線治具（図４，図５）を用いて配索する。   As shown in FIG. 2B, in this example, the special wires 19 are routed one by one above and below the electric wire group 8 respectively. The special wire 19 on the lower side is laid out in the special wire routing groove 5 (FIG. 1) of the wire receiving portion 3, and the special wire 19 on the upper side is, for example, on the top of the wire group 8 after finishing the wiring group 8. Route along the route, or use the wiring jig (FIGS. 4 and 5) described later.

図２（ｂ）の如く、上下の各特殊線１９は電線群８の中心を通る鉛直面上に位置し、図２（ａ）において大きな半径でスムーズに屈曲する（屈曲部を符号１９ａで示す）。例えば特殊線１９’を鎖線の如く電線群８の屈曲内側面に沿って配索した場合には、特殊線１９’が小さな半径で屈曲し、過大な曲げ応力を生じると共に、特殊線１９’の枝寸法すなわち分岐方向の長さが安定しなくなってしまう（例えば特殊線１９’を電線群８の屈曲内側面に沿って配索した場合は線長が長くなり、特殊線１９を電線群８の屈曲外側面に沿って配索した場合は線長が短くなる）。   As shown in FIG. 2B, the upper and lower special lines 19 are located on a vertical plane passing through the center of the wire group 8, and bend smoothly with a large radius in FIG. 2A (the bent portion is indicated by reference numeral 19a). ). For example, when the special line 19 ′ is routed along the bent inner side surface of the electric wire group 8 like a chain line, the special line 19 ′ bends with a small radius, causing an excessive bending stress and the special line 19 ′. The branch dimension, that is, the length in the branch direction becomes unstable (for example, when the special wire 19 ′ is routed along the bent inner surface of the wire group 8, the wire length becomes long, and the special wire 19 is (If the cable is routed along the bent outer surface, the line length will be shorter).

図３（ａ）（ｂ）は、例えば布線後に布線治具１（図２）からワイヤハーネス２０を外した状態での特殊線１９の配索位置ごとの屈曲形態を示すものである。   3 (a) and 3 (b) show, for example, a bent form for each wiring position of the special wire 19 in a state where the wire harness 20 is removed from the wiring jig 1 (FIG. 2) after wiring.

図２（ａ）の実線の如く特殊線１９を電線群８の中心を通る鉛直面上に配置することで図２（ａ）の矢印方向に、図３（ａ）の如く電線群８を小さな半径で折り曲げるように屈曲させた際に、電線群８の屈曲内側面８ｃと屈曲外側面８ｄとの中間で特殊線１９がスムーズに撓んで曲がりを吸収しつつ電線群８よりも大径に屈曲して（屈曲部を符号１９ａで示す）、曲げ応力を軽減させる。特殊線１９は電線群８の屈曲部（交差部）８ｂにおいてはテープ巻き２０等で固定しないで露出させておくことが、電線群８の屈曲の影響を避ける上で好ましい。   By arranging the special wire 19 on the vertical plane passing through the center of the electric wire group 8 as shown by the solid line in FIG. 2A, the electric wire group 8 is made smaller in the direction of the arrow in FIG. 2A. When bent so as to be bent at a radius, the special wire 19 smoothly bends between the bent inner side surface 8c and the bent outer side surface 8d of the wire group 8 to absorb the bending and bend to a larger diameter than the wire group 8. (The bending portion is indicated by reference numeral 19a) to reduce the bending stress. In order to avoid the influence of the bending of the electric wire group 8, it is preferable that the special wire 19 be exposed without being fixed by the tape winding 20 or the like at the bent portion (intersection portion) 8 b of the electric wire group 8.

The upper half wall 33a can be opened and closed by the upper operation lever 40.

アウタ治具２３とインナ治具２４とを図４（ｃ）の矢印Ｄ方向に開いた状態で、区画板３８を撓ませ開いてインナ治具２４の特殊線配索溝３７に特殊線を配索し、区画板３８を自身の弾性力で閉じ、インナ治具２４の電線挿通孔３４を分割して成る電線挿通溝に複数本の電線を配索し、複数本の電線で成る電線群と特殊線とを区画板３８で上下に区画した状態で、インナ治具２４を閉じ、アウタ治具２３を閉じて、アウタ治具２３でインナ治具２４を特殊線と一体に回動自在に保持する。特殊線は円形の電線挿通孔３４の内周面３４ａに沿って下向きにスライドさせつつ特殊線配索溝３７内にスムーズに挿入させることができる。   With the outer jig 23 and the inner jig 24 opened in the direction of arrow D in FIG. 4C, the partition plate 38 is bent and opened to place a special line in the special line routing groove 37 of the inner jig 24. And then closing the partition plate 38 with its own elastic force, routing a plurality of wires in a wire insertion groove formed by dividing the wire insertion hole 34 of the inner jig 24, and a group of wires composed of a plurality of wires In a state where the special line is divided up and down by the partition plate 38, the inner jig 24 is closed, the outer jig 23 is closed, and the inner jig 24 is rotatably held integrally with the special line by the outer jig 23. To do. The special wire can be smoothly inserted into the special wire routing groove 37 while sliding downward along the inner peripheral surface 34 a of the circular electric wire insertion hole 34.

図４（ｃ）の特殊線配索溝３７を鉛直方向下側に配置した状態は図１の実施形態における特殊線配索溝５の位置と同じであり、特殊線は電線群の真下に配索される。この状態から上下のレバー４０の操作でインナ治具２４を矢印Ｄ方向に回動させることで、特殊線を電線挿通孔３４内の電線群に対して周方向の所望の位置に配置（配索）することができる。例えばインナ治具２４を１８０°回転させることで、特殊線を電線群の真上に配索することができ、これは図２の上側の特殊線１９に対応（相当）する。   The state in which the special line routing groove 37 in FIG. 4C is arranged on the lower side in the vertical direction is the same as the position of the special line routing groove 5 in the embodiment of FIG. 1, and the special line is arranged directly below the wire group. Searched for. By rotating the inner jig 24 in the arrow D direction by operating the upper and lower levers 40 from this state, the special wire is arranged at a desired position in the circumferential direction with respect to the electric wire group in the electric wire insertion hole 34 (routing). )can do. For example, by rotating the inner jig 24 by 180 °, the special line can be routed directly above the electric wire group, which corresponds to (corresponds to) the special line 19 on the upper side of FIG.

特殊線を屈曲させずに真直に配索する場合は、例えばインナ治具２４を図４（ｃ）の状態から９０°又は２７０°矢印方向に回転させて、電線群に対して左右何れかの側部に特殊線を配索可能となる。このように、所望の角度でインナ治具２４を回動させて所望の位置に特殊線を配索することができる。何れの場合も特殊線を作業者が手で電線群に固定した状態でヒンジ４１を支点にインナ治具２４を開くことで、特殊線が区画板３８を径方向内向きに撓ませて特殊線配索溝３７からスムーズに離脱する。   In case of straight wiring without bending the special line, for example, the inner jig 24 is rotated 90 ° or 270 ° in the direction of the arrow from the state of FIG. Special lines can be routed on the side. In this way, the special line can be routed at a desired position by rotating the inner jig 24 at a desired angle. In either case, the special line is bent inward in the radial direction by opening the inner jig 24 with the hinge 41 as a fulcrum while the operator manually fixes the special line to the wire group. It smoothly leaves the routing groove 37.

なお、インナ治具２４の上下の壁部３３ａ，３３ｂを上下反転してアウタ治具２３に配置し、インナ治具２４とアウタ治具２３を開いた状態で、電線挿通孔（溝）３４に複数本の電線を配索し、開いた上側の壁部３３ｂの特殊線配索溝３７に特殊線を配索し、インナ治具２４とアウタ治具２３を閉じて、特殊線を電線群の上側に配置した状態で、インナ治具２４を１８０°ないし９０°回転させて特殊線を電線群の下方ないし側方に配置することも可能である。   The upper and lower wall portions 33a and 33b of the inner jig 24 are turned upside down and placed on the outer jig 23, and the inner jig 24 and the outer jig 23 are opened, and the wire insertion hole (groove) 34 is opened. A plurality of wires are routed, a special wire is routed in the special wire routing groove 37 of the opened upper wall portion 33b, the inner jig 24 and the outer jig 23 are closed, and the special wire is connected to the wire group. In a state where it is arranged on the upper side, the inner jig 24 can be rotated 180 ° to 90 ° to arrange the special wire below or on the side of the electric wire group.

また、上記布線治具２１を布線板上に数個（例えば三つ）並べて一直線上ないし折れ線上に配設し、中間（二番目）の布線治具２１のインナ治具（治具部）２４を回転させることで、インナ治具２４内の特殊線の軽微な切断長さ寸法誤差（長過ぎや短すぎ）を吸収させることが可能である。一枚の布線板には多数の布線治具（図１や図４等のものを混載可能）が配置されるが、少なくとも三つの連続（隣接）した布線治具２１においてこの長さ寸法誤差の吸収を行うことができる。   Further, several (for example, three) of the wiring jigs 21 are arranged on a straight line or a broken line, and an inner jig (jig) of the intermediate (second) wiring jig 21 is arranged. Part) 24 can be rotated to absorb minor cutting length dimension errors (too long or too short) of the special line in the inner jig 24. A number of wiring jigs (such as those shown in FIGS. 1 and 4 can be mixed and mounted) are arranged on a single wiring board, but the length of at least three continuous (adjacent) wiring jigs 21 has this length. Absorption of dimensional errors can be performed.

例えば、三つの布線治具２１を直線上に並べた場合に、各インナ治具２４の特殊線挿通溝３７を一直線上に配置する（例えば各特殊線挿通溝を真下に配置する）ことで、特殊線の配索長さは最短になり、その状態から中間の布線治具２１のインナ治具２４を回動させて、そのインナ治具２４の特殊線配索溝３７と他のインナ治具２４の特殊線配索溝３７とを結ぶ仮想線が折れ線となるようにする（例えば中間のインナ治具２４の特殊線配索溝３７のみを真上に配置する）ことで、特殊線が折れ線状に配索されて、特殊線の配索長さが長く（最長に）なる。特殊線の配索長さは、中間のインナ治具２４を１８０°の範囲で回動させる角度が大きくなればなる程、長くなる。このようにして特殊線の長さ寸法誤差を吸収調整することができる。   For example, when the three wiring jigs 21 are arranged on a straight line, the special line insertion grooves 37 of the inner jigs 24 are arranged on a straight line (for example, the special line insertion grooves are arranged directly below). The special wire routing length is the shortest, and the inner jig 24 of the intermediate wiring jig 21 is rotated from that state, so that the special wire routing groove 37 of the inner jig 24 and other inner wires 24 are rotated. By making the imaginary line connecting the special line routing groove 37 of the jig 24 into a broken line (for example, only the special line routing groove 37 of the intermediate inner jig 24 is arranged directly above), the special line Is routed in a polygonal line, and the length of the special line is long (longest). The length of the special line is increased as the angle at which the intermediate inner jig 24 is rotated in the range of 180 ° increases. In this way, the length dimension error of the special line can be absorbed and adjusted.

三つの布線治具２１を折れ線上に並べた場合（例えば中間の布線治具２１を他の前後二つの布線治具２１よりも右側に偏心して配置した場合）は、例えば前後端の二つのインナ治具２４の特殊線配索溝３７を右端に配置し、中間のインナ治具２４の特殊線配索溝３７を左端に配置することで、特殊線の配索長さが最短となり、逆に、前後端の二つのインナ治具２４の特殊線配索溝３７を左端に配置し、中間のインナ治具２４の特殊線配索溝３７を右端に配置することで、特殊線の配索長さが最長となる。このように三つの各インナ治具２４の回動角度を適宜変えることで、特殊線の布線長さを微調整（寸法誤差吸収）することができる。   When three wiring jigs 21 are arranged on a broken line (for example, when the intermediate wiring jig 21 is arranged eccentrically on the right side of the other two front and rear wiring jigs 21), for example, at the front and rear ends. By arranging the special line routing groove 37 of the two inner jigs 24 at the right end and the special line routing groove 37 of the intermediate inner jig 24 at the left end, the special line routing length is minimized. On the contrary, the special line routing groove 37 of the two inner jigs 24 at the front and rear ends is arranged at the left end, and the special line routing groove 37 of the intermediate inner jig 24 is arranged at the right end. The routing length is the longest. In this way, by appropriately changing the rotation angle of each of the three inner jigs 24, the wiring length of the special line can be finely adjusted (absorption of dimensional errors).

また、インナ治具２４の特殊線配索溝３７から前後方向（電線挿通方向）に図１の特殊線ガイド板４３と同様な特殊線ガイド部（図示せず）を突出させて設けることも有効である。特殊線ガイド部は図１の例で説明した各種形態のものを適用可能である。   It is also effective to provide a special wire guide portion (not shown) similar to the special wire guide plate 43 in FIG. 1 in the front-rear direction (wire insertion direction) from the special wire routing groove 37 of the inner jig 24. It is. Various types of special line guide portions described in the example of FIG. 1 can be applied.

また、図４の布線治具２１における各操作レバー２９，４０を排除して、アウタ治具２３とインナ治具２４との外周部に別体の操作レバー（図示せず）を挿入係合させる穴部（図示せず）を設けることも可能である。また、アウタ治具２３の操作レバー２９をコの字状ではなく前後一対の真直なものとしてもよい。また、アウタ治具２３の操作レバー２９を排除して、アウタ治具２３の上半の前後一対の壁部２５ａを手で直接開閉させることも可能である。また、アウタ治具２３の環状壁２５の外周面は円形に限らず矩形状とすることも可能である。   Further, the operation levers 29 and 40 in the wiring jig 21 of FIG. 4 are eliminated, and separate operation levers (not shown) are inserted and engaged with the outer peripheral portions of the outer jig 23 and the inner jig 24. It is also possible to provide a hole portion (not shown). Further, the operation lever 29 of the outer jig 23 may be a straight pair of front and rear instead of a U-shape. It is also possible to directly open and close the pair of front and rear wall portions 25a in the upper half of the outer jig 23 by removing the operation lever 29 of the outer jig 23. Further, the outer peripheral surface of the annular wall 25 of the outer jig 23 is not limited to a circular shape, but may be a rectangular shape.
