ワイヤハーネスの製造には、それぞれ前工程で複数のサブハーネスを別個に組み立て、後工程で複数のサブハーネスを組み合わせて1つのワイヤハーネスを組み立てる方法がよく採用されている。例えば特許文献1には、車種や仕様等によって対応するワイヤハーネスが異なることに鑑み、常設電装装備の信号回路を含む回路群からなる共用回路(共通サブハーネス)と、オプションとなる電装システムの回路群からなる専用回路(オプションサブハーネス)とを別々に形成しておき、複数の作業台上で共用回路と専用回路とのそれぞれのサブハーネスを順番に組み合わせて所望のワイヤハーネスを製造する方法が開示されている。
また、特許文献2にも、全車種で共用されるベース回路部分(共通サブハーネス)と、車種に応じて相違するアドオン回路部分(オプションサブハーネス)とをそれぞれ別の作業台上で組み立てた後、ベース回路部分とアドオン回路部分とを重ねて結束してワイヤハーネスを製造する方法が開示されている。
さらに、特許文献3にも、ベース回路を集合した共通サブハーネスと、特定の回路を集合したオプションサブハーネスとに分けて生産し、これらのサブハーネスを選択的に組み合わせてワイヤハーネスを製造する方法が開示されている。

ところで、このようなサブハーネスの組立は、所定位置に例えばU字状の電線受け治具を立設させた組立作業台が用いられる。すなわち、サブハーネスを電線受け治具に通して結束やコネクタの接続作業等を行うものであるが、特にオプションサブハーネスにおいては、特許文献2にも開示のように、オプションサブハーネス用の組立作業台上において、後工程で共通サブハーネスと結束しない部分を構成する電線を電線受け治具に通して布線する一方、共通サブハーネスと結束する部分を2つの電線受け治具間に垂らした状態で組み立てて結束し、このオプションサブハーネスを共通サブハーネス用の組立作業台上で共通サブハーネスに重ねて配索して結束する手順となる。
しかし、オプションサブハーネスの位置決めは電線受け治具に載せるのみであるため、作業中に共通サブハーネスとの結束部分と非結束部分との境界がずれるおそれがある。従って、そのまま結束したオプションサブハーネスを共通サブハーネスに重ね合わせると、互いの重ね合わせ部分に寸法のずれが生じ、仕様に合致せず不良となってしまう。
By the way, for assembling such a sub-harness, an assembly work table in which, for example, a U-shaped wire receiving jig is erected at a predetermined position is used. That is, the sub-harness is passed through the electric wire receiving jig to perform bundling, connector connection work, etc. Especially in the optional sub-harness, as disclosed in Patent Document 2, assembly work for the optional sub-harness On the table, the wires that make up the part that is not bound to the common sub-harness in the subsequent process are routed through the wire receiving jig, while the part that is tied to the common sub-harness is suspended between the two wire receiving jigs In this procedure, the optional sub-harness is assembled and bundled, and the optional sub-harness is overlaid on the common sub-harness on the assembly work table for the common sub-harness and wired and bound.
However, since the optional sub-harness is only placed on the electric wire receiving jig, the boundary between the binding portion and the non-binding portion with the common sub-harness may be shifted during the operation. Therefore, if the optional sub-harnesses that are bundled as they are are superimposed on the common sub-harness, a dimensional deviation occurs in the overlapping portions, resulting in failure to meet the specifications.

そこで、本発明は、このように前工程でサブハーネスを個別に組み立てて後工程で重ね合わせて結束する製造工程においても、サブハーネス同士の重ね合わせをずれのない高い寸法精度で行うことができる電線固定具及びワイヤハーネスの製造方法を提供することを目的としたものである。   Therefore, the present invention can perform the superposition of the sub-harnesses with high dimensional accuracy without deviation even in the manufacturing process in which the sub-harnesses are individually assembled in the preceding process and overlapped and bound in the post-process as described above. It aims at providing the manufacturing method of an electric wire fixing tool and a wire harness.

And in the electric wire clamping part 7 isolate | separated by the slit 8, the rubber pad 9 as an elastic material is accommodated in the folded shape across the concave grooves 6 and 6 of both the clamping plates 2 and 2 on the wide side. Yes.

次に、この固定具1を用いたワイヤハーネスの製造方法について説明する。
基本的な手順は先の背景技術で説明した内容と同じで、共通サブハーネスとオプションサブハーネスとにそれぞれ対応した組立作業台が用いられ、電線受け治具に電線を通して結束やコネクタの接続作業等が行われる(前工程)。また、オプションサブハーネスの組立作業台(第1の組立作業台)において、後工程で共通サブハーネスと結束しない部分を構成する電線を電線受け治具に通して布線する一方、共通サブハーネスと結束する部分を2つの電線受け治具間に垂らした状態で組み立てて結束することになる。
Next, a method for manufacturing a wire harness using the fixture 1 will be described.
The basic procedure is the same as that described in the background art above, using an assembly worktable corresponding to each of the common sub-harness and the optional sub-harness. Is performed (previous process). In addition, in the optional sub-harness assembly workbench (first assembly workbench), the wires constituting the portion not bound to the common sub-harness in the subsequent process are routed through the wire receiving jig, while the common sub-harness and The parts to be bound are assembled and bound in a state where they are suspended between two wire receiving jigs.

図4は、オプションサブハーネスの組立作業台(第1の組立作業台)10の一例を示すもので、ここでは一対の支持棒12,12を上向きに突設したU字状の電線受け治具11にオプションサブハーネス13を通して分岐させ、各分岐線14,14にコネクタ15を接続する作業等が行われる。16は、電線受け治具11と同様に組立作業台10上に立設されたコネクタ固定治具である。   FIG. 4 shows an example of an optional sub-harness assembly work table (first assembly work table) 10. Here, a U-shaped electric wire receiving jig in which a pair of support rods 12, 12 are projected upward. 11 is branched through the option sub-harness 13, and the work of connecting the connector 15 to the branch lines 14 and 14 is performed. Reference numeral 16 denotes a connector fixing jig erected on the assembly work table 10 in the same manner as the wire receiving jig 11.

電線受け治具11は、共通サブハーネスとの結束部分と非結束部分の境界となる二箇所(図4では一方のみ示している。)に設けられるもので、この電線受け治具11に固定具1を、基端同士を互いの接近側へ押圧して先端間を開いた状態で、スリット8に電線受け治具11の支持棒12,12を挿入させ、電線挟持部7で支持棒12に隣接するオプションサブハーネス13を挟持させる。すると、図5,6に示すように、オプションサブハーネス13は、固定具1を介して、共通サブハーネスとの結束部分と非結束部分との境界位置となる電線受け治具11に固定されることになる。このとき、固定具1のスリット8には支持棒12,12が直交状に貫通しているので、固定具1がオプションサブハーネス13の長手方向にずれることはない。   The wire receiving jig 11 is provided at two places (only one is shown in FIG. 4) which is a boundary between the binding portion and the non-binding portion with the common sub-harness. 1, with the base ends pressed against each other and opened between the ends, the support rods 12, 12 of the wire receiving jig 11 are inserted into the slit 8, and the wire holding portion 7 attaches the support rod 12 to the support rod 12. The adjacent optional sub harness 13 is clamped. Then, as shown in FIGS. 5 and 6, the optional sub-harness 13 is fixed to the wire receiving jig 11 that is a boundary position between the binding portion and the non-binding portion with the common sub-harness via the fixture 1. It will be. At this time, since the support rods 12, 12 penetrate perpendicularly into the slit 8 of the fixture 1, the fixture 1 does not shift in the longitudinal direction of the option sub-harness 13.

こうして境界位置を固定具1で固定した状態で、オプションサブハーネス13の端末にコネクタ15を接続する等の作業が行われる。ここではオプションサブハーネス13が電線受け治具11に固定されることで、各コネクタ15との間の分岐線14を弛むことなく張り渡すことができ、作業性は良好となる。
そして、オプションサブハーネス13の組み立てが終了すると、固定具1と共にオプションサブハーネス13を上に持ち上げれば、図7に示すように、支持棒12,12から固定具1ごとオプションサブハーネス13を抜き取って組立作業台10から取り外すことができる。このとき、依然として固定具1は電線挟持部7でオプションサブハーネス13を挟持したままであるから、固定具1がオプションサブハーネス13から外れたり位置ずれしたりすることはない。
In a state where the boundary position is fixed by the fixing tool 1 in this manner, operations such as connecting the connector 15 to the terminal of the option sub-harness 13 are performed. Here, by fixing the optional sub-harness 13 to the electric wire receiving jig 11, the branch line 14 between each connector 15 can be stretched without loosening, and the workability is improved.
When the assembly of the option sub-harness 13 is completed, if the option sub-harness 13 is lifted together with the fixture 1, the option sub-harness 13 is pulled out together with the fixture 1 from the support rods 12 and 12, as shown in FIG. Can be removed from the assembly workbench 10. At this time, since the fixture 1 still holds the option sub-harness 13 with the electric wire clamping portion 7, the fixture 1 is not detached from the option sub-harness 13 or displaced.

そして、図8に示すように、後工程では、組み立てたオプションサブハーネス13を、共通サブハーネス23の組立作業台(第2の組立作業台)20に搬送し、共通サブハーネス23に重ねてセットする。ここでは、共通サブハーネス23におけるオプションサブハーネス13との結束部分と非結束部分との2つの境界位置に電線受け治具21(図8では一方のみ示している。)が設けられており、この電線受け治具21においても固定具1(以下、区別する必要がある場合は共通サブハーネス側を1A、オプションサブハーネス側を1Bと表記する)がそれぞれ設けられて共通サブハーネス23が固定された状態で組み立てが行われている。よって、オプションサブハーネス13を重ねる際には、オプションサブハーネス13側の固定具1Bのスリット8に、支持棒22,22をオプションサブハーネス13を跨いて下方から貫通させて固定具1Aの上に重ねれば、電線受け治具21に固定することができる。   Then, as shown in FIG. 8, in the subsequent process, the assembled optional sub-harness 13 is transported to the assembly work table (second assembly work table) 20 of the common sub-harness 23 and set on the common sub-harness 23. To do. Here, an electric wire receiving jig 21 (only one of them is shown in FIG. 8) is provided at two boundary positions between the binding portion and the non-binding portion with the optional sub harness 13 in the common sub harness 23. The electric wire receiving jig 21 is also provided with the fixture 1 (hereinafter, when it is necessary to distinguish between them, the common sub-harness side is denoted as 1A and the optional sub-harness side is denoted as 1B), and the common sub-harness 23 is fixed. Assembly is performed in the state. Therefore, when the option sub-harness 13 is stacked, the support rods 22 and 22 are passed through the option sub-harness 13 from the lower side to the slit 8 of the fixing tool 1B on the option sub-harness 13 side, and placed on the fixing tool 1A. If they are stacked, they can be fixed to the wire receiving jig 21.

このように互いの固定具1A,1Bを重ねて同じ電線受け治具21にセットすることで、図9,10に示すように、オプションサブハーネス13と共通サブハーネス23とは互いの結束部分と非結束部分との境界位置が一致した状態で重ね合わされることになる。よって、両サブハーネスの互いの結束部分について寸法ずれは生じない。
なお、さらに別のオプションサブハーネスを重ねる場合は、そのまま固定具1Bの上から同様に当該オプションサブハーネスに固定した固定具1に支持棒22,22を下から貫通させて重ねれば、このオプションサブハーネスも互いの結束部分と非結束部分との境界位置が一致した状態で重ね合わせることができる。
As shown in FIGS. 9 and 10, the optional sub-harness 13 and the common sub-harness 23 are connected to each other as shown in FIGS. 9 and 10 by overlapping the fixtures 1 </ b> A and 1 </ b> B and setting them on the same wire receiving jig 21. The overlapping is performed in a state where the boundary position with the non-binding portion is coincident. Therefore, a dimensional shift does not occur in the binding portions of both sub-harnesses.
In addition, when another optional sub-harness is to be stacked, if the support rods 22 and 22 are passed through the fixture 1 fixed to the option sub-harness from the bottom in the same manner, the option sub-harness can be used. The sub-harnesses can also be overlapped with the boundary position between the binding portion and the non-binding portion being matched.

こうして各サブハーネス13,23の重ね合わせを行った後、オプションサブハーネス13と共通サブハーネス23との互いの結束部分にテープ24を巻き付ける等して結束作業を行うことができる。
ワイヤハーネスの組み立てが終了すれば、図11に示すように、各固定具1の基端同士を押圧して先端間を開き、サブハーネスの挟持を解除した状態で、スリット8から支持棒22,22を抜き取るようにスライドさせれば、各固定具1をサブハーネスから取り外すことができる。後は電線受け治具21からワイヤハーネス25を上方へ抜き取ればよい。
After superimposing the sub-harnesses 13 and 23 in this way, the binding work can be performed by winding the tape 24 around the binding part of the optional sub-harness 13 and the common sub-harness 23.
When the assembly of the wire harness is completed, as shown in FIG. 11, the base ends of the fixtures 1 are pressed together to open the ends, and the sub-harness is released. If it slides so that 22 may be extracted, each fixing tool 1 can be removed from a subharness. Thereafter, the wire harness 25 may be extracted upward from the wire receiving jig 21.

このように、上記形態の固定具1及びワイヤハーネスの製造方法によれば、サブハーネスを挟持したまま電線受け治具へ着脱可能となるクリップ状の固定具1を用いて、境界位置の電線受け治具11に支持させたオプションサブハーネス13を挟持した状態でオプションサブハーネス13を組み立て、共通サブハーネス23への重ね合わせの際には、電線受け治具11からオプションサブハーネス13を固定具1ごと抜き外して、当該固定具1を組立作業台20の電線受け治具21に取り付けて、オプションサブハーネス13と共通サブハーネス23との結束を行うようにしたことで、オプションサブハーネス13と共通サブハーネス23とをそれぞれ前工程で個別に組み立てて後工程で両者を重ね合わせて結束する製造工程であっても、サブハーネス同士の重ね合わせをずれのない高い寸法精度で行うことができ、品質の良好なワイヤハーネスを製造することができる。また、オプションサブハーネス13が組立作業台10上で適正に位置決めされることで、従来後工程で行っていた分岐の処理や保護材の装着作業等を前工程で行えることになり、前工程と後工程での作業負荷の偏りの分散にも繋がる。   Thus, according to the fixing device 1 and the method of manufacturing the wire harness of the above-described form, the clip-shaped fixing device 1 that can be attached to and detached from the wire receiving jig while holding the sub-harness is used to The optional sub-harness 13 is assembled in a state where the optional sub-harness 13 supported by the jig 11 is sandwiched, and when being superimposed on the common sub-harness 23, the optional sub-harness 13 is fixed from the wire receiving jig 11 to the fixture 1. The fixture 1 is attached to the electric wire receiving jig 21 of the assembly work table 20 and the optional sub-harness 13 and the common sub-harness 23 are bound together. Even in the manufacturing process in which the sub-harnesses 23 are individually assembled in the pre-process and then overlapped and bundled in the post-process, Can be carried out with no high dimensional accuracy deviation superposition of the harness between, it is possible to produce a good wire harness in quality. In addition, when the optional sub-harness 13 is properly positioned on the assembly workbench 10, the branching process and the attaching work of the protective material, which are conventionally performed in the post-process, can be performed in the pre-process. This also leads to the distribution of work load bias in the subsequent process.

特にここでは、組立作業台20において、境界位置の電線受け治具21に支持させた共通サブハーネス23を固定具1Aで挟持した状態で共通サブハーネス23を組み立て、オプションサブハーネス13の重ね合わせの際には、オプションサブハーネス13側の固定具1Bを共通サブハーネス23側の固定具1Aの上に重ねて電線受け治具21に取り付けるようにしているので、共通サブハーネス23も固定具1Aによって適正に位置決めされ、オプションサブハーネス13との重ね合わせをより簡単且つ正確に行うことができる。   In particular, here, in the assembly work table 20, the common sub-harness 23 supported by the wire receiving jig 21 at the boundary position is sandwiched between the fixtures 1A, and the optional sub-harness 13 is overlapped. At this time, since the fixing tool 1B on the option sub-harness 13 side is overlaid on the fixing tool 1A on the common sub-harness 23 side and attached to the electric wire receiving jig 21, the common sub-harness 23 is also attached to the fixing tool 1A. It is positioned appropriately and can be easily and accurately overlapped with the optional sub-harness 13.

一方、固定具1においても、電線挟持部7を形成する挟持板2,2の端部内面にゴムパッド9を設けているので、電線挟持部7で挟持するサブハーネスを滑り止めして固定具1と好適に一体化させることができる。   On the other hand, in the fixture 1, the rubber pad 9 is provided on the inner surface of the end portions of the clamping plates 2 and 2 that form the wire clamping portion 7, so that the sub-harness clamped by the wire clamping portion 7 is prevented from slipping. And can be suitably integrated.

なお、固定具は、上記形態に限らず、例えば挟持板をピンでなく凹凸同士の嵌合で回転可能に連結したり、付勢手段として板バネ等の他の部材を用いたり、スリットを挟持板の幅方向の中央に設けたり、スリットを複数設けて何れかのスリットを選択して支持棒の挿脱を可能としたり等、適宜変更可能である。
また、スリットを挟んだ挟持板の左右での長手方向の寸法は同じである必要はなく、電線挟持部の反対側は少なくとも挟持板に近い側の支持棒に係止できれば足りるため、電線挟持部側よりも短くして差し支えない。
さらに、電線挟持部の内面に用いる弾性材としてそれぞれ別個のゴムシートを内面に貼着したりしてもよいし、このような弾性材をなくして内面に凹凸や歯を一体形成して滑り止めを図ったりしてもよい。
Note that the fixing device is not limited to the above-described form. For example, the holding plate is rotatably connected by fitting the concaves and convexes instead of the pins, or another member such as a leaf spring is used as the biasing means, or the slit is held. It can be appropriately changed, such as being provided at the center in the width direction of the plate, or by providing a plurality of slits and selecting one of the slits to allow the support rod to be inserted and removed.
In addition, the left and right longitudinal dimensions of the sandwiching plate sandwiching the slit need not be the same, and it is sufficient that the opposite side of the wire sandwiching portion can be locked to at least the support rod near the sandwiching plate. It can be shorter than the side.
Furthermore, a separate rubber sheet may be attached to the inner surface as an elastic material used for the inner surface of the electric wire clamping part, or such an elastic material is eliminated to form an uneven surface and teeth on the inner surface to prevent slipping. You may plan.

一方、ワイヤハーネスの製造方法においても、上記形態では共通サブハーネスにおける結束部分と非結束部分との境界位置にも固定具を用いているが、ここでの固定具をなくして、オプションサブハーネスにおける結束部分と非結束部分との境界位置にのみ固定具を用いるようにしてもよい。この場合共通サブハーネスの境界位置は電線受け治具のみによって支持されることになるが、オプションサブハーネスで境界位置が確実に位置決めされているので、重ね合わせの際の寸法精度は維持できる。   On the other hand, in the method of manufacturing the wire harness, in the above embodiment, the fixture is also used at the boundary position between the binding portion and the non-binding portion in the common sub-harness. You may make it use a fixing tool only in the boundary position of a binding part and a non-binding part. In this case, the boundary position of the common sub-harness is supported only by the electric wire receiving jig. However, since the boundary position is reliably positioned by the optional sub-harness, the dimensional accuracy at the time of superposition can be maintained.
