Description

本発明は、電線挿通具およびその誘導治具に関する。   The present invention relates to an electric wire insertion tool and its guide jig.

筒状のコルゲートチューブに電線または電線束を挿通させるためのコルゲートチューブ用電線挿通具が知られている（特許文献１参照）。
この電線挿通具は、スリットを有しない筒状のコルゲートチューブに電線を挿通させるために用いられる。電線挿通具は、電線の先端を後端に開口した挿入口から挿入して電線を収容する収容部と、収容部の先端部を先端にかけて縮幅させてなり、コルゲートチューブ内で収容部をガイドするガイド部とを備える。収容部は、電線の先端を挿入する挿入口が、後端に複数並べて開口されている。収容部の後端面の下部からは、収容部に挿入された電線を下側から支持する受部が、後方に延びている。 There is known a corrugated tube wire insertion tool for inserting a wire or a bundle of wires through a cylindrical corrugated tube (see Patent Document 1).
This electric wire insertion tool is used for inserting an electric wire through a cylindrical corrugated tube having no slit. The wire insertion tool is formed by inserting the leading end of the electric wire from the insertion opening opened at the rear end and accommodating the electric wire, and reducing the width of the leading end of the accommodating portion toward the leading end, and guiding the accommodating portion within the corrugated tube. And a guide portion. The housing part is opened with a plurality of insertion openings for inserting the front end of the electric wires arranged at the rear end. From the lower part of the rear end surface of the housing part, a receiving part that supports the electric wire inserted into the housing part from below is extended rearward.

この電線挿通具によれば、電線挿通具の収容部に先端を挿入した電線を、コルゲートチューブ内に送り込むことで、電線の先端とコルゲートチューブの内面との接触を避け、コルゲートチューブの内面や電線を傷つけることなく、電線をコルゲートチューブ内に挿通させることができる。このため、コルゲートチューブにスリットを設けることなく電線や電線束をコルゲートチューブに容易に挿通することができる。   According to this electric wire insertion tool, by feeding the electric wire having the tip inserted into the housing portion of the electric wire insertion tool into the corrugated tube, contact between the electric wire tip and the inner surface of the corrugated tube is avoided, and the inner surface of the corrugated tube and the electric wire are prevented. The wire can be inserted into the corrugated tube without damaging the wire. For this reason, an electric wire and an electric wire bundle can be easily inserted in a corrugated tube, without providing a slit in a corrugated tube.

特開２０１０−１０４０８２号公報JP 2010-104082 A

ところで、電線または電線束は、断面形状の異なる２つ以上のコルゲートチューブにそれぞれ挿通したい場合がある。例えば、コルゲートチューブは、一般的に円形断面を有する丸型コルゲートチューブであるが、車体取付部に対する高さ制約等がある部分の配索では、扁平断面を有する平型コルゲートチューブを用いることがある。この場合、電線挿通具は、平型コルゲートチューブには平型用が用いられ、丸型コルゲートチューブには丸型用が用いられる。
しかしながら、従来の電線挿通具は、コルゲートチューブの断面形状に合ったものを使用しているため、軸方向に並べた断面形状の異なる複数のコルゲートチューブには、連続して挿通させることが不可能となる。即ち、平型用電線挿通具は、平型コルゲートチューブには挿通可能であるが、内径が平型用電線挿通具の横幅よりも小さい丸型コルゲートチューブには挿通不可となる。逆に、丸型用電線挿通具は、開口高さが丸型用電線挿通具の外径よりも低い平型コルゲートチューブには挿通不可であるが、丸型コルゲートチューブには挿通可能となる。このため、コルゲートチューブの断面形状にあわせて、手作業にて平型用電線挿通具と丸型用電線挿通具を付け替える煩雑な作業が必要となる。 By the way, an electric wire or an electric wire bundle may want to be inserted through two or more corrugated tubes having different cross-sectional shapes. For example, the corrugated tube is generally a round corrugated tube having a circular cross section, but a flat corrugated tube having a flat cross section may be used in the routing of a portion having a height restriction with respect to the vehicle body mounting portion. . In this case, as the wire insertion tool, a flat corrugated tube is used for a flat shape, and a round corrugated tube is used for a round shape.
However, since the conventional wire insertion tool uses one that matches the cross-sectional shape of the corrugated tube, it is impossible to continuously insert it into a plurality of corrugated tubes with different cross-sectional shapes arranged in the axial direction. It becomes. That is, the flat wire insertion tool can be inserted into the flat corrugated tube, but cannot be inserted into a round corrugated tube whose inner diameter is smaller than the lateral width of the flat wire insertion tool. Conversely, the round wire insertion tool cannot be inserted into a flat corrugated tube whose opening height is lower than the outer diameter of the round wire insertion tool, but can be inserted into the round corrugated tube. For this reason, according to the cross-sectional shape of a corrugated tube, the complicated operation | work which replaces the flat wire insertion tool and the round wire insertion tool manually is required.

本発明は上記状況に鑑みてなされたもので、その目的は、断面形状が異なる２つ以上の電線保護部材に連続して電線を容易に挿通できる電線挿通具およびその誘導治具を提供することにある。   The present invention has been made in view of the above situation, and an object thereof is to provide a wire insertion tool that can easily insert an electric wire continuously through two or more electric wire protection members having different cross-sectional shapes, and an induction jig thereof.

While being rotated by about 90 degrees, they are moved to the inside of the radius of rotation and overlapped in the vertical direction. That is, the three electric wires become a bundle of electric wires arranged close to each other in the radial direction.
Thereby, from a wire protection member having an oval cross section through which three electric wires are inserted side by side, a circular cross section through which the three electric wires are inserted in close proximity to each other in a radial direction The electric wire can be continuously inserted into the electric wire protection member.

The vertical / horizontal first guide portion 59 that is the first guide portion of the vertical / horizontal guide jig 55 first contacts the side of the first insertion tool body 13 as shown in the AA cross section of FIG. . In the process of inserting the wire insertion tool 11, the vertical and horizontal first guide part 59 moves the first insertion tool body 13 to one side as shown in the BB cross section to the DD cross section, and then the second insertion tool. A horizontal space 61 of the main body 15 is formed.

縦横誘導治具５５の第２案内部である縦横第２案内部６３は、図５（ｂ）のＡ−Ａ断面に示すように、最初に第２の挿通具本体１５に当接していない。縦横第２案内部６３は、電線挿通具１１の挿通過程において、Ｂ−Ｂ断面〜Ｄ−Ｄ断面に示すように、第２の挿通具本体１５を片側に寄せた後、第２の挿通具本体１５を水平空間６１に案内する。即ち、縦横第２案内部６３は、第１の挿通具本体１３に対し縦方向から添えられた状態の第２の挿通具本体１５を、第１の挿通具本体１３に対し横方向から添えられる状態に回動させる。   The vertical and horizontal second guide portion 63 that is the second guide portion of the vertical and horizontal guide jig 55 does not first contact the second insertion tool main body 15 as shown in the AA cross section of FIG. In the insertion process of the wire insertion tool 11, the vertical and horizontal second guide part 63 moves the second insertion tool body 15 to one side as shown in the BB cross section to the DD cross section, and then the second insertion tool. The main body 15 is guided to the horizontal space 61. That is, the vertical and horizontal second guide portions 63 attach the second insertion tool main body 15 attached to the first insertion tool main body 13 from the vertical direction to the first insertion tool main body 13 from the horizontal direction. Rotate to state.

一方、横縦誘導治具５７は、一端開口部５１が、図６（ｂ）に示すように、第２の挿通具本体１５が横方向から添えられた電線挿通具１１を挿入可能としている。横縦誘導治具５７の第１案内部である横縦第１案内部６５は、図７（ｂ）のＥ−Ｅ断面に示すように、最初に第１の挿通具本体１３の上方に当接する。横縦第１案内部６５は、電線挿通具１１の挿通過程において、Ｆ−Ｆ断面〜Ｈ−Ｈ断面に示すように、第１の挿通具本体１３を一定位置に保持しながら片側に寄って、第２の挿通具本体１５の垂直空間６７を形成する。   On the other hand, as shown in FIG. 6B, the horizontal and vertical guide jig 57 allows the one end opening 51 to insert the wire insertion tool 11 with the second insertion tool body 15 attached from the horizontal direction. The horizontal and vertical first guide portion 65, which is the first guide portion of the horizontal and vertical guide jig 57, is first placed above the first insertion tool body 13 as shown in the EE cross section of FIG. Touch. In the insertion process of the wire insertion tool 11, the horizontal and vertical first guide part 65 moves toward one side while holding the first insertion tool body 13 at a fixed position as shown in the FF cross section to the HH cross section. A vertical space 67 of the second insertion tool body 15 is formed.

横縦誘導治具５７の第２案内部である横縦第２案内部６９は、図７（ｂ）のＥ−Ｅ断面に示すように、最初に第２の挿通具本体１５の下方に当接している。横縦第２案内部６９は、電線挿通具１１の挿通過程において、Ｆ−Ｆ断面〜Ｈ−Ｈ断面に示すように、第２の挿通具本体１５を上昇させた後、第２の挿通具本体１５を垂直空間６７に案内する。即ち、横縦第２案内部６９は、第１の挿通具本体１３に対し横方向から添えられた状態の第２の挿通具本体１５を、第１の挿通具本体１３に対し縦方向から添えられる状態に回動させる。   The horizontal and vertical second guide portion 69, which is the second guide portion of the horizontal and vertical guide jig 57, is first placed below the second insertion tool main body 15 as shown in the EE cross section of FIG. It touches. In the insertion process of the wire insertion tool 11, the horizontal and vertical second guide portion 69 raises the second insertion tool body 15 and then moves the second insertion tool 15 as shown in the FF cross section to the HH cross section. The main body 15 is guided to the vertical space 67. That is, the horizontal and vertical second guide portion 69 attaches the second insertion tool body 15 attached to the first insertion tool body 13 from the horizontal direction to the first insertion tool body 13 from the vertical direction. Rotate to a state where

次に、本実施形態に係る電線挿通具１１の変形例を説明する。
図８に示すように、この変形例に係る電線挿通具７１は、２本の電線１７を挿入する第１の挿通具本体１３に対し、２つの第２の挿通具本体１５が、第１の挿通具本体１３の中心軸周りを平行な状態で回動自在に連結されている。 Next, a modification of the wire insertion tool 11 according to the present embodiment will be described.
As shown in FIG. 8, the wire insertion tool 71 according to this modification has two second insertion tool bodies 15 that are different from the first insertion tool body 13 into which the two wires 17 are inserted. The insertion tool main body 13 is connected so as to be rotatable around the central axis in a parallel state.

２つの第２の挿通具本体１５は、同一の回転方向へ移動された後に、第１の挿通具本体１３を挟む位置に配置される。即ち、図８（ａ）に示す横並び状態では、第１の挿通具本体１３が、横方向から一対の第２の挿通具本体１５によって挟まれる。図８（ｂ）に示す縦並び状態では、第１の挿通具本体１３が、縦方向から一対の第２の挿通具本体１５によって挟まれる。   The two second insertion tool main bodies 15 are arranged at positions sandwiching the first insertion tool main body 13 after being moved in the same rotation direction. That is, in the side-by-side state shown in FIG. 8A, the first insertion tool body 13 is sandwiched between the pair of second insertion tool bodies 15 from the lateral direction. In the vertically aligned state shown in FIG. 8B, the first insertion tool body 13 is sandwiched between the pair of second insertion tool bodies 15 from the vertical direction.

この変形例に係る電線挿通具７１によれば、４本の電線１７を、断面形状の異なる丸型コルゲートチューブ４５又は平型コルゲートチューブ４３に連続して挿通できる。   According to the wire insertion tool 71 according to this modification, the four electric wires 17 can be continuously inserted into the round corrugated tube 45 or the flat corrugated tube 43 having different cross-sectional shapes.

次に、電線挿通具１１、並びに誘導治具である縦横誘導治具５５及び横縦誘導治具５７を用いた電線挿通方法の一例を説明する。
図９は電線挿通具１１が異なる断面形状の電線保護部材に挿通される過程を表した動作説明図である。
この電線挿通方法では、３本の電線１７が、丸型コルゲートチューブ４５、平型コルゲートチューブ４３、丸型コルゲートチューブ４５の順で挿通される。最初の丸型コルゲートチューブ４５と平型コルゲートチューブ４３との間には、縦横誘導治具５５が配置される。平型コルゲートチューブ４３と最後の丸型コルゲートチューブ４５との間には、横縦誘導治具５７が配置されている。 Next, an example of an electric wire insertion method using the electric wire insertion tool 11 and the vertical and horizontal induction jigs 55 and the horizontal and vertical induction jigs 57 which are induction jigs will be described.
FIG. 9 is an operation explanatory view showing a process in which the wire insertion tool 11 is inserted through the wire protection members having different cross-sectional shapes.
In this electric wire insertion method, the three electric wires 17 are inserted in the order of the round corrugated tube 45, the flat corrugated tube 43, and the round corrugated tube 45. A vertical and horizontal guide jig 55 is disposed between the first round corrugated tube 45 and the flat corrugated tube 43. A horizontal / vertical guide jig 57 is disposed between the flat corrugated tube 43 and the last round corrugated tube 45.

先ず、電線挿通具１１の第１の挿通具本体１３には２本の電線１７が挿通され、第２の挿通具本体１５には１本の電線１７が挿通される（図９（ａ）参照）。
そして、３本の電線１７が挿入された電線挿通具１１は、丸型コルゲートチューブ４５へ挿通される（図９（ｂ）参照）。この際、電線挿通具１１は、図３に示したように第１の挿通具本体１３に対し第２の挿通具本体１５が縦方向から添えられている。これにより、電線挿通具１１は、丸型コルゲートチューブ４５へ挿通可能となっている。電線１７が押し込まれることで、丸型コルゲートチューブ４５に挿通された電線挿通具１１は、丸型コルゲートチューブ４５から出されると、縦横誘導治具５５に進入する（図９（ｃ）参照）。 First, two electric wires 17 are inserted into the first insertion tool main body 13 of the electric wire insertion tool 11, and one electric wire 17 is inserted into the second insertion tool main body 15 (see FIG. 9A). ).
And the electric wire penetration tool 11 in which the three electric wires 17 were inserted is penetrated by the round corrugated tube 45 (refer FIG.9 (b)). At this time, the wire insertion tool 11 has a second insertion tool body 15 attached to the first insertion tool body 13 from the vertical direction as shown in FIG. Thereby, the wire insertion tool 11 can be inserted into the round corrugated tube 45. When the electric wire 17 is pushed in, the electric wire insertion tool 11 inserted into the round corrugated tube 45 enters the vertical and horizontal guide jig 55 when the electric wire insertion tool 11 is taken out from the round corrugated tube 45 (see FIG. 9C).

縦横誘導治具５５に進入した電線挿通具１１は、第１の挿通具本体１３に対し縦方向から添えられた状態の第２の挿通具本体１５が、図１に示したように第１の挿通具本体１３に対し横方向から添えられる状態に回動させる。これにより、電線挿通具１１は、断面形状が異なる平型コルゲートチューブ４３へ挿通が可能となり、連続して平型コルゲートチューブ４３へ押し込まれる（図９（ｄ）参照）。   As shown in FIG. 1, the wire insertion tool 11 that has entered the vertical and horizontal guide jig 55 has the second insertion tool body 15 attached to the first insertion tool body 13 from the vertical direction as shown in FIG. 1. The insertion tool main body 13 is rotated so as to be attached from the lateral direction. Thereby, the wire insertion tool 11 can be inserted into the flat corrugated tube 43 having a different cross-sectional shape, and is continuously pushed into the flat corrugated tube 43 (see FIG. 9D).

電線１７が押し込まれることで、平型コルゲートチューブ４３に挿通された電線挿通具１１は、平型コルゲートチューブ４３から出されると、横縦誘導治具５７に進入する（図９（ｅ）参照）。横縦誘導治具５７に進入した電線挿通具１１は、第１の挿通具本体１３に対し横方向から添えられた状態の第２の挿通具本体１５が、再び第１の挿通具本体１３に対し縦方向から添えられる状態に回動される。電線挿通具１１は、丸型コルゲートチューブ４５へ挿通可能となり、丸型コルゲートチューブ４５へ押し込まれる（図９（ｆ）参照）。
そして、電線１７が更に押し込まれることで、丸型コルゲートチューブ４５の終端側から電線挿通具１１が出る。 When the electric wire 17 is pushed in, the electric wire insertion tool 11 inserted through the flat corrugated tube 43 enters the horizontal / vertical guide jig 57 when the electric wire inserting tool 11 comes out of the flat corrugated tube 43 (see FIG. 9E). . The wire insertion tool 11 that has entered the horizontal / vertical guide jig 57 has the second insertion tool body 15 attached to the first insertion tool body 13 from the lateral direction again to the first insertion tool body 13. On the other hand, it is rotated so as to be attached from the vertical direction. The wire insertion tool 11 can be inserted into the round corrugated tube 45 and is pushed into the round corrugated tube 45 (see FIG. 9F).
And the electric wire insertion tool 11 comes out from the termination | terminus side of the round corrugated tube 45 because the electric wire 17 is pushed further.

丸型コルゲートチューブ４５の終端側から電線挿通具１１と共に引き出された３本の電線１７は、縦横誘導治具５５及び横縦誘導治具５７の蓋部４９がそれぞれ開かれることで、縦横誘導治具５５及び横縦誘導治具５７から外される。その結果、３本の電線１７は、丸型コルゲートチューブ４５、平型コルゲートチューブ４３、丸型コルゲートチューブ４５のみに通された状態となる。   The three electric wires 17 drawn out together with the electric wire insertion tool 11 from the terminal end side of the round corrugated tube 45 are opened by the lid portions 49 of the vertical / horizontal guide jig 55 and the horizontal / vertical guide jig 57, respectively. The tool 55 and the horizontal / vertical guide jig 57 are removed. As a result, the three electric wires 17 are passed through only the round corrugated tube 45, the flat corrugated tube 43, and the round corrugated tube 45.

これにより、断面形状の異なる丸型コルゲートチューブ４５、平型コルゲートチューブ４３、丸型コルゲートチューブ４５に対し、電線挿通具１１が順次に自動的に変形することで、３本の電線１７の連続した挿通作業が容易に完了する。   Accordingly, the wire insertion tool 11 is automatically and sequentially deformed with respect to the round corrugated tube 45, the flat corrugated tube 43, and the round corrugated tube 45 having different cross-sectional shapes, so that the three wires 17 are continuous. Insertion work is completed easily.

なお、上述の電線挿通方法では、最初の丸型コルゲートチューブ４５と平型コルゲートチューブ４３との間に縦横誘導治具５５を配置し、平型コルゲートチューブ４３と最後の丸型コルゲートチューブ４５との間に横縦誘導治具５７を配置した。しかし、コルゲートチューブには、これら縦横誘導治具５５及び横縦誘導治具５７と同様の構造を付与することができる。即ち、図示は省略するが、丸型コルゲートチューブ４５と平型コルゲートチューブ４３を丸平型コルゲートチューブとして一体に成形し、接続部分の内面に、縦横誘導治具５５における縦横第１案内部５９及び縦横第２案内部６３に相当する案内部を形成することができる。また、平型コルゲートチューブ４３と丸型コルゲートチューブ４５を平丸型コルゲートチューブとして一体に成形し、接続部分の内面に、横縦誘導治具５７における横縦第１案内部６５及び横縦第２案内部６９に相当する案内部を形成することができる。   In the above-described electric wire insertion method, the vertical / horizontal guide jig 55 is disposed between the first round corrugated tube 45 and the flat corrugated tube 43, and the flat corrugated tube 43 and the last round corrugated tube 45 are connected to each other. A horizontal / vertical guide jig 57 was disposed between them. However, the corrugated tube can be provided with the same structure as the vertical and horizontal guide jigs 55 and the horizontal and vertical guide jigs 57. That is, although not shown, the round corrugated tube 45 and the flat corrugated tube 43 are integrally formed as a round flat corrugated tube, and the first and second first and second guide portions 59 and 59 in the vertical and horizontal guide jig 55 are formed on the inner surface of the connecting portion. A guide portion corresponding to the vertical and horizontal second guide portions 63 can be formed. Further, the flat corrugated tube 43 and the round corrugated tube 45 are integrally formed as a flat round corrugated tube, and the first and second horizontal and vertical guide portions 65 and 2 of the horizontal and vertical guide jig 57 are formed on the inner surface of the connecting portion. A guide portion corresponding to the portion 69 can be formed.

このような丸平型コルゲートチューブや平丸型コルゲートチューブによれば、縦横誘導治具５５や横縦誘導治具５７を使用せずに、電線挿通具１１のみを用いて電線１７を連続して異なる断面形状の電線保護部材に挿通することができる。   According to such a round flat corrugated tube or a flat round corrugated tube, the electric wires 17 are continuously different using only the electric wire insertion tool 11 without using the vertical / horizontal guiding jig 55 and the horizontal / vertical guiding jig 57. It can be inserted into a cross-sectional shape electric wire protection member.

次に、上記構成を有する電線挿通具１１の作用を説明する。
本実施形態に係る電線挿通具１１では、挿通具本体が、第１の挿通具本体１３と第２の挿通具本体１５とからなる。第２の挿通具本体１５は、第１の挿通具本体１３に対して、第１の挿通具本体１３の中心軸周りを平行な状態で、回動自在に第１の挿通具本体１３に連結されている。 Next, the effect | action of the electric wire penetration tool 11 which has the said structure is demonstrated.
In the wire insertion tool 11 according to the present embodiment, the insertion tool main body includes a first insertion tool main body 13 and a second insertion tool main body 15. The second insertion tool body 15 is connected to the first insertion tool body 13 so as to be rotatable in a state parallel to the first insertion tool body 13 around the central axis of the first insertion tool body 13. Has been.

即ち、第２の挿通具本体１５が、第１の挿通具本体１３の軸線直交断面における輪郭に沿う方向に平行移動することができる。そこで、第１の挿通具本体１３の軸線直交断面が扁平（例えば長円）であれば、第２の挿通具本体１５は、この扁平形状の輪郭に沿って平行移動することができる。   That is, the second insertion tool main body 15 can be translated in a direction along the contour in the cross section perpendicular to the axis of the first insertion tool main body 13. Therefore, if the cross section orthogonal to the axis of the first insertion tool main body 13 is flat (for example, an ellipse), the second insertion tool main body 15 can be translated along the flat outline.

このように、互いに中心軸周りを平行な状態で回動自在に連結された第１の挿通具本体１３と第２の挿通具本体１５を可動させることで、電線保護部材の断面形状に合わせた形状に、電線挿通具１１の軸線直交断面形状が変形可能となる。
従って、中心軸が互いに平行に設けられた第１の挿通具本体１３と第２の挿通具本体１５とは、挿通する電線保護部材の開口形状に合わせて、電線１７を横に添えた状態から縦に添える状態、或いはその逆に、縦に添えた状態から横に添える状態に回動させて保持することができる。 In this way, the first insertion tool body 13 and the second insertion tool body 15 that are rotatably connected to each other around the central axis are movable to match the cross-sectional shape of the wire protection member. The shape of the cross section of the wire insertion tool 11 perpendicular to the axis is deformable.
Therefore, the first insertion tool main body 13 and the second insertion tool main body 15 whose central axes are provided in parallel to each other are in a state in which the electric wires 17 are attached to the sides in accordance with the opening shape of the electric wire protection member to be inserted. It can be rotated and held from a vertically attached state, or vice versa, from a vertically attached state to a horizontally attached state.

また、本実施形態の電線挿通具１１では、３本の電線１７を横に並べた状態では、第１の挿通具本体１３に挿入された２本の電線１７に対し、第２の挿通具本体１５に挿入された１本の電線１７が横に添えられる。   Moreover, in the electric wire insertion tool 11 of this embodiment, in the state which arranged the three electric wires 17 side by side, with respect to the two electric wires 17 inserted in the 1st insertion tool main body 13, the 2nd insertion tool main body. One electric wire 17 inserted into 15 is attached to the side.

第２の挿通具本体１５が可動して電線１７が縦に添えられる状態では、第１の挿通具本体１３の横並びの２本の電線１７に対し、第２の挿通具本体１５の１本の電線１７が、回転角度で約９０度回転しつつ、回転半径内側へ移動されて、縦方向から重ねられて並ぶ。即ち、３本の電線１７は、近接して放射方向に配置された電線束となる。   In a state where the second insertion tool main body 15 is movable and the electric wire 17 is vertically attached, one of the second insertion tool main body 15 is compared with the two electric wires 17 arranged side by side in the first insertion tool main body 13. The electric wires 17 are moved to the inside of the rotation radius while rotating about 90 degrees at the rotation angle, and are arranged in a stacked manner from the vertical direction. That is, the three electric wires 17 become a bundle of electric wires arranged close to each other in the radial direction.

これにより、３本の電線１７が横に並んで挿通される長円形の断面を有する平型コルゲートチューブ４３から、３本の電線１７が近接して放射方向に配置された電線束で挿通される円形の断面を有する丸型コルゲートチューブ４５への電線１７の連続した挿通が可能となる。   Thereby, the three electric wires 17 are inserted by the electric wire bundle which adjoined and was arrange | positioned in the radial direction from the flat corrugated tube 43 which has the oval cross section through which the three electric wires 17 are inserted side by side. The electric wire 17 can be continuously inserted into the round corrugated tube 45 having a circular cross section.

次に、上記構成を有する誘導治具（縦横誘導治具５５及び横縦誘導治具５７）の作用を説明する。
