When the corrugated tube is used as an exterior material, the corrugated tube can be bent in any direction of the entire circumference, so that the bending direction cannot be regulated and there is a possibility of contacting with peripheral devices. In addition, if the wiring space has a square cross section, the number of wires in the wire harness that can be inserted into the wiring space decreases when the wire harness covered with a round corrugated tube is passed, and the wiring space cannot be used effectively. There is.
前記問題に対して、本出願人は特開2013-49402号公報で図8(A)(B)(C)に示すように、スライドシート150に接続するワイヤハーネス200の外装材100として、組立式四角筒状のキャタピラ型の外装材を提供している。該キャタピラ型の外装材100は図8(B)に示すように、樹脂製の帯状の平板101に長さ方向Xに延在する4本の折曲ラインA~Dを幅方向Yの中間部に間隔をあけて設け、かつ、幅方向の両側縁の一方側に係止突片102を設けると共に他方側に係止穴103を設け、折曲ラインA~Dに沿って折り曲げて四角筒形状とすると共に、係止穴103に係止突片102を挿入係止して四角筒に保持している。さらに、折曲ラインA~Dを結ぶ幅方向に切込ラインKを長さ方向に間隔をあけて設け、四角筒の3辺111、112、113を分離させ、係止突片102と係止穴103とで係止する辺114は切込ラインKが無いため分離せずに長さ方向Xに連続させている。
With respect to the above problem, the present applicant has assembled an exterior material 100 for the wire harness 200 connected to the slide sheet 150 as shown in FIGS. 8 (A), (B), and (C) in JP2013-49402A. Caterpillar-type exterior material with a square tube shape. As shown in FIG. 8 (B), the caterpillar type exterior material 100 includes four bent lines A to D extending in the longitudinal direction X on a resin-made strip-like flat plate 101 in the middle in the width direction Y. Are provided at intervals, and a locking protrusion 102 is provided on one side of both side edges in the width direction, and a locking hole 103 is provided on the other side, and is bent along the folding lines A to D to form a square cylinder. At the same time, the locking protrusions 102 are inserted and locked in the locking holes 103 and held in the square tube. Further, a cut line K is provided in the width direction connecting the bent lines A to D with a distance in the length direction to separate the three sides 111, 112, 113 of the square tube, and the locking protrusion 102 is locked. Since there is no cut line K, the side 114 to be locked with the hole 103 is not separated and is continuous in the length direction X.
前記のように組み立てた外装材100は、前記切込ラインKが無い辺114は伸びることができず、図8(C)に示すように、ワイヤハーネス200に外装した外装材100は、辺112が外周側となる一方向きC1にのみ屈曲でき、辺114が外周側となる他方向きC2に屈曲できない。
このように、前記外装材100は一方向にのみ屈曲できるため、屈曲方向を規制して周辺機器との接触を防止する必要があるワイヤハーネスの外装材として好適に用いられる。 In theexterior material 100 assembled as described above, the side 114 without the cut line K cannot extend, and as shown in FIG. 8C, the exterior material 100 sheathed on the wire harness 200 has the side 112. Can be bent only in one direction C1 on the outer peripheral side, and cannot be bent in the other direction C2 on the outer peripheral side.
Thus, since theexterior material 100 can be bent only in one direction, it is suitably used as an exterior material for a wire harness that needs to regulate the bending direction and prevent contact with peripheral devices.
このように、前記外装材100は一方向にのみ屈曲できるため、屈曲方向を規制して周辺機器との接触を防止する必要があるワイヤハーネスの外装材として好適に用いられる。 In the
Thus, since the
前記のように、特許文献1のキャタピラ型の外装材100は、幅方向の切込ラインKにより一方向に屈曲させることができる利点がある。よって、図9に示すように、スライドシート150に接続するスライドシート用のワイヤハーネス200を外装材100で外装し、該ワイヤハーネスの上方の一端P1をスライドシート150の下面に固定し、下方の他端P2をフロア160側に固定して用いることができる。
As described above, the caterpillar-type exterior material 100 of Patent Document 1 has an advantage that it can be bent in one direction by the cut line K in the width direction. Therefore, as shown in FIG. 9, the wire harness 200 for the slide sheet connected to the slide sheet 150 is covered with the exterior material 100, and the upper end P <b> 1 of the wire harness is fixed to the lower surface of the slide sheet 150. The other end P2 can be fixed to the floor 160 side.
前記のように、スライドシートとフロアとの間に配索するスライドシート用のワイヤハーネス200はスライドシート150の図9中矢印FRで示す前後移動に追従して外装材100で外装したワイヤハーネスが矢印frで示す前後方向に移動する。其の際、外装材100は外周側に切込ラインKを設けた辺112が位置し、スライドシート150の下面と対向して位置する。
As described above, the wire harness 200 for the slide sheet that is routed between the slide sheet and the floor is a wire harness that is sheathed with the exterior material 100 following the back-and-forth movement of the slide sheet 150 indicated by the arrow FR in FIG. It moves in the front-rear direction indicated by the arrow fr. At that time, the exterior material 100 has a side 112 provided with a cutting line K on the outer peripheral side, and is positioned to face the lower surface of the slide sheet 150.
前記外装材100は切込ラインKがない辺114が屈曲しにくいため、屈曲領域Zの曲率が大きくなり、辺114の内周側と辺112の外周側の外周差によるズレが発生し、図9に示すように、外周面の辺112の切込ラインKの開きが大きくなり、大きな隙間が発生し、該隙間から埃、砂等の異物が侵入しやすくなり、異物により隙間が閉じられなくなると、外装材がスムーズに移動できなくなる問題もある。
かつ、外装材100で外装したワイヤハーネスを湾曲して配索するスライドシート下面とフロア側の間の配索スペースの上下高さは狭いため、外装材100が大きな曲率でしか曲がれないと、上下高さは大となり、ワイヤハーネスの配索ができなくなる恐れもある。 In theexterior material 100, since the side 114 without the cutting line K is difficult to bend, the curvature of the bending region Z is increased, and a deviation due to the outer peripheral difference between the inner peripheral side of the side 114 and the outer peripheral side of the side 112 occurs. As shown in FIG. 9, the opening of the cut line K on the side 112 of the outer peripheral surface becomes large, a large gap is generated, and foreign matters such as dust and sand easily enter from the gap, and the gap cannot be closed by the foreign matter. There is also a problem that the exterior material cannot be moved smoothly.
In addition, since the vertical height of the wiring space between the lower surface of the slide sheet and the floor side where the wire harness sheathed with theexterior material 100 is curved and routed is narrow, if the exterior material 100 can be bent only with a large curvature, The height becomes large, and there is a possibility that the wiring harness cannot be routed.

本発明は前記キャタピラ型の外装材において、屈曲可能とするための幅方向の切り込みを設けながら、該切り込みで分離された隣接辺の間の隙間を無くし、かつ、小さな曲率で屈曲できるようにして、配索スペースの上下寸法が小さい場合にも容易に配索できるようにすることを課題としている。
The present invention provides the caterpillar-type exterior material, while providing a cut in the width direction for enabling bending, eliminating a gap between adjacent sides separated by the cut and allowing bending with a small curvature. It is an object to enable easy routing even when the vertical dimension of the routing space is small.

前記本発明のキャタピラ型の外装材では、第1部材および第2部材とも長さ方向に間隔をあけて上壁から縦壁へと連続する切り込みを幅方向に設け、該第1、第2部材を組み合わせて四角筒とした状態で、上壁および左右縦壁は切り込みで分割しているが、下壁はヒンジ部で連結しているため、前記特許文献1で提示したキャタピラ型の外装材と同様に上壁が外周側となって屈曲できるが、内周側の下壁は屈曲できず、屈曲方向を規制できるキャタピラ型の外装材とすることができる。
このように、第1、第2部材の下壁を平板状とせず、長さ方向に間隔をあけてヒンジ部を設けているため、上壁と同様に容易に屈曲でき、上壁を外周、下壁を内周とすると、内外周差を小さくして、屈曲時に内周側となる下壁も屈曲しやすくなり、外装材の全体を屈曲時に曲率を小さくでき、配置スペースを減少できる。かつ、外周側となる上壁の切り込みを大きく広がるのを抑制できる。 In the caterpillar-type exterior material of the present invention, both the first member and the second member are provided in the width direction with continuous cuts from the upper wall to the vertical wall at intervals in the length direction.

It is set as the structure fitted to the said notch of an upper wall.
前記第1部材および第2部材は樹脂成形品からなり、ワイヤハーネスの電線群を集束保護する必要がある外装領域に連続して外装できる長さを有するものとしている。ワイヤハーネスの電線群は第2部材の縦壁と対向する開口から横入れして挿通し、その後、該第2部材に第1部材を組み合わせて四角筒とし、第1、第2部材の対向する縦壁と上下に重なる上壁および下壁で挿通する電線群を囲んでいる。第1部材と第2部材は長さ方向の両端で引き出されるワイヤハーネスの電線群とテープ巻き固着して、四角筒に組み立てた第1部材と第2部材とを連結固着すると共に、該第1、第2部材と電線群も固着している。即ち、長さ方向の両端を除く部分では、第1部材と第2部材とはテープ巻き等で連結固着しておらず上壁および縦壁に前記切り込みにより分割片を設け、下壁をヒンジ部を介して連結することで屈曲自在となる機能を持たせている。
The first member and the second member are made of a resin molded product, and have a length capable of being continuously sheathed in an exterior region where it is necessary to focus and protect the electric wire group of the wire harness. The wire group of the wire harness is inserted horizontally through the opening facing the vertical wall of the second member, and then the first member is combined with the second member to form a square tube, and the first and second members face each other. It encloses a group of wires inserted through the upper and lower walls that overlap the vertical wall. The first member and the second member are taped and fixed to the wire harness of the wire harness drawn out at both ends in the length direction, and the first member and the second member assembled into a square tube are connected and fixed, and the first member The second member and the wire group are also fixed. That is, in the portion excluding both ends in the length direction, the first member and the second member are not connected and fixed by tape winding or the like, and the upper wall and the vertical wall are provided with the divided pieces by the above-mentioned cuts, and the lower wall is the hinge portion. It has a function to be bendable by being connected via the.
また、本発明の外装材では、外面側となる第1部材の上壁の切り込みに下面から第2部材の段状突起を嵌合することで、前記切り込みにより生じる隙間を下面側の第2部材の上壁で塞いで無くしている。よって、ワイヤハーネスおよび外装材が湾曲し、切り込みを挟む分割片が離れて隙間ができても、前記段状突起を突出した第2部材の上壁で前記隙間の下面を閉鎖できる。
Further, in the exterior material of the present invention, the stepped protrusion of the second member is fitted from the lower surface to the notch of the upper wall of the first member on the outer surface side, so that the gap generated by the notch is reduced to the second member on the lower surface side. The upper wall is closed and lost. Therefore, even if the wire harness and the exterior material are curved and the separated pieces sandwiching the notch are separated to form a gap, the lower surface of the gap can be closed by the upper wall of the second member protruding the stepped protrusion.
さらに、第1部材の縦壁に設ける切り込みは細幅直線状としている一方、第2部材の縦壁に設ける切り込みは下壁に向けて広がる台形状とし、該第2部材の広い切り込みと対応する位置の下壁の中央に突出部を設けると共に該突出部を挟んで2個の薄肉ヒンジ部を設けることが好ましい。
これにより、第1部材の縦壁が外周面、第2部材の縦壁が内周面となると、屈曲時に、内周側の2つの薄肉ヒンジ部の変形により小さい曲率で屈曲でき、プロテクタ全体の屈曲性を高めることができる。 Further, the cut provided in the vertical wall of the first member is a narrow straight line, while the cut provided in the vertical wall of the second member is a trapezoidal shape extending toward the lower wall, corresponding to the wide cut of the second member. It is preferable to provide a protrusion at the center of the lower wall of the position and to provide two thin hinge portions sandwiching the protrusion.
Thus, when the vertical wall of the first member is the outer peripheral surface and the vertical wall of the second member is the inner peripheral surface, at the time of bending, the two thin hinge portions on the inner peripheral side can be bent with a smaller curvature, and the entire protector Flexibility can be improved.

前記本発明のワイヤハーネス用外装材は、自動車に搭載するスライドシートとフロアとの間に配索するスライドシート用のワイヤハーネスの外装材として好適に用いられる。
具体的には、前記スライドシート用のワイヤハーネスは、フロアハーネスの幹線から分岐する枝線からなる電線群、前記枝線にコネクタ接続する電線群、あるいは前記スライドシート内に配索するシートハーネスからフロア側へ延在させて前記フロアハーネスとコネクタ接続する電線群からなり、スライドシートの下面と車室床面材下方のフロアパネルとの間に前記外装材で外装した状態で横向きJ形状に配索される。詳細には、スライドシート側との固定点からスライドシート下面に引き出される外装材は、その上壁をスライドシートの下面に沿って後方へと水平方向に延在し、後端側で下方にU字状に湾曲した後に前方へ水平に延在し、その先端をフロア側に固定している。 The wire harness exterior material of the present invention is suitably used as an exterior material for a wire harness for a slide sheet routed between a slide sheet mounted on an automobile and a floor.
Specifically, the wire harness for the slide seat is an electric wire group consisting of branch lines branching from a trunk line of a floor harness, an electric wire group connected to the branch wire by a connector, or a seat harness routed in the slide seat. It consists of a group of electric wires that extend to the floor side and connect to the floor harness, and is arranged in a lateral J shape with the exterior covering between the lower surface of the slide seat and the floor panel below the passenger compartment floor covering. Searched for. Specifically, the exterior material drawn out from the fixed point on the slide sheet side to the lower surface of the slide sheet extends in the horizontal direction rearward along the lower surface of the slide sheet, and U on the rear end side. After curving in a letter shape, it extends horizontally forward and its tip is fixed to the floor.

It consists of a group of electric wires that extend to the floor side and connect to the floor harness, and is arranged in a lateral J shape with the exterior covering between the lower surface of the slide seat and the floor panel below the passenger compartment floor covering. Searched for. Specifically, the exterior material drawn out from the fixed point on the slide sheet side to the lower surface of the slide sheet extends in the horizontal direction rearward along the lower surface of the slide sheet, and U on the rear end side. After curving in a letter shape, it extends horizontally forward and its tip is fixed to the floor.
前記のように、スライドシートの下面に沿って横向きU字状に配索するワイヤハーネスを前記外装材で外装すると、スライドシートの下面に近接して配置される外装材の上壁を直線に保持でき、スライドシートの下面と外装材が接触するのを防止できる。かつ、横向きU字の上下高さを低くできるため、スライドシート下方の狭いスペースにワイヤハーネスを配索することができる。
As described above, when a wire harness arranged in a U shape in a horizontal direction along the lower surface of the slide sheet is packaged with the exterior material, the upper wall of the exterior material arranged close to the lower surface of the slide sheet is held in a straight line. It is possible to prevent the lower surface of the slide sheet from contacting the exterior material. And since the up-and-down height of horizontal U character can be made low, a wire harness can be routed in the narrow space below a slide seat.
本発明のワイヤハーネス用の外装材は、第1部材および第2部材とも長さ方向に間隔をあけて上壁から縦壁へと連続する切り込みを幅方向に設け、かつ、前記上壁の切り込みと対向する下壁に薄肉ヒンジ部を設けて、第1、第2部材とも上壁は前記切り込みにより両側片が開閉して屈曲すると共に下壁は前記薄肉ヒンジ部が変形して両側片が屈曲できるようにしている。よって、該第1、第2部材を組み合わせて四角筒とした状態で、上壁および左右縦壁の3辺の切り込みで長さ方向に分割片を連続し、下壁の薄肉ヒンジ部で続壁としているため、上壁が外周側となって屈曲できるが、内周側の下壁は屈曲できず、屈曲方向を規制できる機能を保持する。
The exterior material for a wire harness according to the present invention is provided with a cut in the width direction in which the first member and the second member are spaced from each other in the length direction and continuous from the upper wall to the vertical wall. A thin hinge is provided on the lower wall opposite to the upper wall of both the first and second members, and both side pieces are opened and closed by the notch and bent, and the lower wall is bent and both side pieces are bent. I can do it. Therefore, in a state where the first and second members are combined into a square tube, the divided pieces are continuous in the length direction by cutting three sides of the upper wall and the left and right vertical walls, and the connecting wall is formed by the thin hinge portion of the lower wall. Therefore, the upper wall can be bent on the outer peripheral side, but the lower wall on the inner peripheral side cannot be bent, and the function of regulating the bending direction is retained. *
特に、前記従来例では下壁は連続しているために屈曲しにくく、横向きU字状に配索すると、屈曲部は大きな曲率となって、上下高さが大きくなるが、本発明の外装材では、第1、第2部材とも下壁に間隔をあけて薄肉ヒンジ部を設けて屈曲しやすくしているため、屈曲部の曲率を小さくでき、配索スペースの上下高さを減少できる。
In particular, in the conventional example, since the lower wall is continuous, it is difficult to bend, and when arranged in a lateral U shape, the bent portion has a large curvature and the vertical height increases, but the exterior material of the present invention Then, since both the first and second members are provided with a thin hinge portion with a space in the lower wall to facilitate bending, the curvature of the bent portion can be reduced and the vertical height of the routing space can be reduced.
さらに、外周側となる第1部材の上壁の切り込みに下面から第2部材の段状突起を嵌合することで、前記切り込みにより生じる隙間を下面側の第2部材の上壁で塞いで無くしている。よって、ワイヤハーネスおよび外装材が湾曲し、切り込みを挟む分割片が離れて隙間ができても、前記段状突起を突出した第2部材の上壁で前記隙間の下面を閉鎖し、埃や砂等の異物の侵入を防止できる。
Further, by fitting the stepped protrusion of the second member from the lower surface into the cut of the upper wall of the first member on the outer peripheral side, the gap caused by the cut is blocked by the upper wall of the second member of the lower surface side. ing. Therefore, even if the wire harness and the exterior material are curved and the divided pieces that sandwich the notch are separated to form a gap, the lower surface of the gap is closed by the upper wall of the second member protruding the stepped protrusion, and dust or sand Intrusion of foreign matter such as can be prevented.
以下、本発明のワイヤハーネス用の外装材の実施形態を図面を参照して説明する。
本発明の外装材は、図1に示すようなキャタピラ型の外装材1からなる。該外装材1は、縦壁の上下両端に上壁と下壁を連続させたコ字形状の第1部材2と第2部材3とを組み合わせて四角筒とし、該四角筒の内部空間を電線群を集束したワイヤハーネス200(図5に示す)の挿通路としている。 Hereinafter, an embodiment of an exterior material for a wire harness of the present invention will be described with reference to the drawings.
The exterior material of this invention consists of a caterpillar-type exterior material 1 as shown in FIG. The exterior material 1 is a rectangular tube formed by combining a U-shaped first member 2 and a second member 3 in which an upper wall and a lower wall are connected to upper and lower ends of a vertical wall, and the inner space of the rectangular tube is an electric wire. The group is used as an insertion path of the converged wire harness 200 (shown in FIG. 5).
本発明の外装材は、図1に示すようなキャタピラ型の外装材1からなる。該外装材1は、縦壁の上下両端に上壁と下壁を連続させたコ字形状の第1部材2と第2部材3とを組み合わせて四角筒とし、該四角筒の内部空間を電線群を集束したワイヤハーネス200(図5に示す)の挿通路としている。 Hereinafter, an embodiment of an exterior material for a wire harness of the present invention will be described with reference to the drawings.
The exterior material of this invention consists of a caterpillar-
図3(A)~(E)に示す第1部材2は、縦壁2aの上端から上壁2b、下端から下壁2cが横向きに突設したコ字形状である。縦壁2aに長さ方向Xに一定間隔をあけて上下全長に切り込み2dを設け、該切り込み2dの上端に連続させて上壁2bの突出端へと幅方向Yの切り込み2eを設けている。即ち、切り込み2dと2eとからなる連続したL形状の切り込みを縦壁2aから上壁2bにかけて設けている。これにより、第1部材2の上壁2bは切り込み2eを挟む分割片2fが長さ方向に並設し、各分割片2fは縦壁2aの切り込み2dで分割された分割片2gにそれぞれ連続する。即ち、分割片2f、2gが連続したL字片が長さ方向に並ぶ形状としている。また、上壁2bの各分割片2fの下面には、その長さ方向の中央位置で段状突起2kを切り込み2eと平行に突設している。
The first member 2 shown in FIGS. 3 (A) to 3 (E) has a U-shape in which an upper wall 2b is projected from the upper end of the vertical wall 2a and a lower wall 2c is projected from the lower end in a lateral direction. The vertical wall 2a is provided with a notch 2d in the entire length in the longitudinal direction X with a constant interval, and a notch 2e in the width direction Y is provided at the protruding end of the upper wall 2b so as to be continuous with the upper end of the notch 2d. That is, a continuous L-shaped cut made of the cuts 2d and 2e is provided from the vertical wall 2a to the upper wall 2b. As a result, the upper wall 2b of the first member 2 has the split pieces 2f sandwiching the notch 2e arranged in the length direction, and each split piece 2f is continuous with the split pieces 2g divided by the notch 2d of the vertical wall 2a. . In other words, L-shaped pieces having continuous pieces 2f and 2g are arranged in the length direction. Further, on the lower surface of each divided piece 2f of the upper wall 2b, a stepped protrusion 2k is provided in parallel with the notch 2e at the central position in the length direction.
下壁2cは切り込み2dに連続した位置に先端まで薄肉とした1つのヒンジ部2hを設け、該ヒンジ部2hを挟む両側を屈曲自在な分割片2iとし、該分割片2iを前記分割片2g、2fに連続させている。このように、第1部材2は上壁2bおよび縦壁2aが切り込み2e、2dを開いて屈曲した時に下壁2cはヒンジ部2hを変形しながら追従して屈曲できるようにしている。即ち、従来の連続辺と比較して曲がり易くしている。
The lower wall 2c is provided with one hinge portion 2h that is thin to the tip at a position continuous with the notch 2d, and both sides sandwiching the hinge portion 2h are bendable split pieces 2i. The split piece 2i is the split piece 2g, 2f is continued. Thus, when the upper wall 2b and the vertical wall 2a are bent by opening the notches 2e and 2d, the lower wall 2c can be bent following the first member 2 while deforming the hinge portion 2h. That is, it is easier to bend than the conventional continuous side.
図4(A)~(D)に示す第2部材3は、第1部材2と同様なコ字形状で、縦壁3aの上端から上壁3b、下端から下壁3cが横向きに突設している。縦壁3aに長さ方向Xに一定間隔をあけて上下全長に切り込み3dを設け、該切り込み3dを上端から下端にかけて長さ方向の切り込み幅が次第に広がる台形状としている。切り込み3dの幅狭な上端に連続して上壁3bに突出端へと切り込み3eを設けている。このように、切り込み3dと3eとからなる連続した切り込みを縦壁3aから上壁3bにかけて設けて、第2部材3の上壁3bは切り込み3eを挟む分割片3fが長さ方向に並び、各分割片3fは縦壁3aの切り込み3dで分割された分割片3gにそれぞれ連続する。即ち、第1部材2と同様に、分割片3f、3gが連続したL字片が長さ方向に並ぶ形状としている。また、上壁3bの各分割片3fの上面には、その長さ方向の中央位置で段状突起3kを切り込み3eと平行に突設している。
The second member 3 shown in FIGS. 4 (A) to 4 (D) has a U-shape similar to that of the first member 2, and the upper wall 3b extends from the upper end of the vertical wall 3a and the lower wall 3c protrudes from the lower end sideways. ing. The vertical wall 3a is provided with cuts 3d along the entire length thereof at regular intervals in the length direction X. The cuts 3d have a trapezoidal shape in which the cut width in the lengthwise direction gradually increases from the upper end to the lower end. A notch 3e is provided on the upper wall 3b to the projecting end continuously from the narrow upper end of the notch 3d. In this way, continuous cuts made of the cuts 3d and 3e are provided from the vertical wall 3a to the upper wall 3b, and the upper wall 3b of the second member 3 is divided into pieces 3f that sandwich the cut 3e in the length direction, The divided pieces 3f are respectively continuous with the divided pieces 3g divided by the cuts 3d of the vertical wall 3a. That is, like the first member 2, L-shaped pieces in which the divided pieces 3f and 3g are continuous are arranged in the length direction. Further, on the upper surface of each divided piece 3f of the upper wall 3b, a stepped protrusion 3k is provided in parallel with the cut 3e at the center position in the length direction.
第2部材3の下壁3cには切り込み3dの幅広な下端に連続した位置に薄肉とした2個のヒンジ部3h1と3h2を突出部3jを挟んで設けている。このように両側に2個のヒンジ部3h1と3h2を設けることにより第2部材3の下壁3cを小さい曲率で屈曲可能としている。前記突出部3jは上壁3bの切り込み3eと対向して位置する。このように、切り込み3dの下端と対応する位置に、ヒンジ部3h1、突出部3j、ヒンジ部3h2を設けているため、下壁3cの屈曲自在な分割片3iは上壁の分割片3fに比較して幅狭となっている。該形状としているため、上壁3bおよび縦壁3aが切り込み3e、3dを開いて屈曲した時に下壁3cはヒンジ部3h1、3h2を変形しながら追従して屈曲できるようにしている。即ち、従来の連続辺と比較して曲がり易くしている。
The lower wall 3c of the second member 3 is provided with two thin hinge portions 3h1 and 3h2 sandwiching the protruding portion 3j at a position continuous with the wide lower end of the cut 3d. Thus, by providing the two hinge portions 3h1 and 3h2 on both sides, the lower wall 3c of the second member 3 can be bent with a small curvature. The protrusion 3j is positioned to face the cut 3e of the upper wall 3b. Thus, since the hinge part 3h1, the protrusion part 3j, and the hinge part 3h2 are provided at a position corresponding to the lower end of the notch 3d, the flexible split piece 3i of the lower wall 3c is compared with the split piece 3f of the upper wall. And it is narrow. Because of this shape, when the upper wall 3b and the vertical wall 3a are bent by opening the cuts 3e and 3d, the lower wall 3c can be bent while following the deformation of the hinge portions 3h1 and 3h2. That is, it is easier to bend than the conventional continuous side.
前記第1部材2の切り込み2d、2eおよび第2部材3の切り込み3d、3eの幅寸法aは約1mmとしている。また、第1、第2部材2、3の段状突起2k、3kの幅bは前記幅aより僅かに小さくし、切り込み2eに段状突起3k、切り込み3eに段状突起2kを挿入すると、隙間なく嵌合できるようにしている。
The width dimension a of the notches 2d and 2e of the first member 2 and the notches 3d and 3e of the second member 3 is about 1 mm. Further, the width b of the stepped protrusions 2k and 3k of the first and second members 2 and 3 is slightly smaller than the width a, and when the stepped protrusion 3k is inserted into the notch 2e and the stepped protrusion 2k is inserted into the notch 3e, It can be fitted with no gap.
また、前記第2部材3の縦壁3aの上下寸法は第1部材2の縦壁2aの上下寸法より小さくし、図1(C)および図2(A)~(C)に示すように、 第1部材2と第2部材3の縦壁2aと3aを対向配置し、第1部材2の上壁2bの下面を第2部材3の上壁3bに載せると共に、第1部材2の下壁2cの上面に第2部材3の下壁3cを載せて、第1、第2部材2、3を四角筒状に組み立てられるようにしている。
Further, the vertical dimension of the vertical wall 3a of the second member 3 is made smaller than the vertical dimension of the vertical wall 2a of the first member 2, and as shown in FIGS. 1 (C) and 2 (A) to (C), The vertical walls 2a and 3a of the first member 2 and the second member 3 are arranged to face each other, the lower surface of the upper wall 2b of the first member 2 is placed on the upper wall 3b of the second member 3, and the lower wall of the first member 2 The lower wall 3c of the second member 3 is placed on the upper surface of 2c so that the first and second members 2 and 3 can be assembled into a rectangular tube shape.
かつ、組み立て時に、第1部材2の縦壁2aの切り込み2dと第2部材3の縦壁3aの切り込み3dを対向させず、長さ方向Xに交互に千鳥配置で位置させ、第1部材2の上壁2bの切り込み2eに第2部材3の上向きの段状突起3kを挿入し、第2部材3の上壁3bの切り込み3eに第1部材2の下向きの段状突起2kを挿入している。かつ、第1部材2の下壁2c上に第2部材3の下壁3cがかさなり、下壁2cのヒンジ部2hの上面に下壁3cの分割片3iの長さ方向の中央が位置し、該下壁2cの分割片2iの長さ方向の中央に下壁3cのヒンジ部3h1、突出部3j、ヒンジ部3h2が位置する。このように、四角筒状に組み立てる外装材1の外周側となる上面の切り込み2eに段状突起3kが嵌合して、図2に示すように、段状突起3kを挟む上面の分割片2fが直線状となるように保持している。
At the time of assembling, the notches 2d of the vertical wall 2a of the first member 2 and the notches 3d of the vertical wall 3a of the second member 3 are positioned so as to be alternately arranged in a staggered manner in the length direction X, so that the first member 2 An upward stepped protrusion 3k of the second member 3 is inserted into the notch 2e of the upper wall 2b, and a downward stepped protrusion 2k of the first member 2 is inserted into the notch 3e of the upper wall 3b of the second member 3. Yes. And the lower wall 3c of the 2nd member 3 becomes bulky on the lower wall 2c of the 1st member 2, The center of the length direction of the division piece 3i of the lower wall 3c is located in the upper surface of the hinge part 2h of the lower wall 2c, The hinge portion 3h1, the protruding portion 3j, and the hinge portion 3h2 of the lower wall 3c are located at the center of the lower wall 2c in the length direction of the divided piece 2i. In this way, the stepped protrusion 3k is fitted into the notch 2e on the upper surface which is the outer peripheral side of the exterior material 1 assembled into a square tube shape, and as shown in FIG. 2, the divided piece 2f on the upper surface sandwiching the stepped protrusion 3k. Is held in a straight line.
前記第1部材2と第2部材3とから組み立てる外装材1は、ワイヤハーネス200の電線群を集束保護する必要がある外装領域に連続して外装できる長さとしている。
図5に示すように、外装材1で複数の電線からなるワイヤハーネス200を外装する作業は、まず、第2部材3に対して縦壁3aと対向する開口からワイヤハーネス200の電線を長さ方向に対して直交方向から横入れして、長尺な第2部材3の内部にワイヤハーネス200を挿通する。ついで、該第2部材3に第1部材2を外嵌して組み合わせ、四角筒とし、第1、第2部材2、3の対向する縦壁2a、3aと上下に重なる上壁2bと3bおよび下壁2cと3cでワイヤハーネス200の電線群を囲む。 Theexterior material 1 assembled from the first member 2 and the second member 3 has a length that allows the exterior of the wire group 200 to be continuously exteriorized in an exterior region that needs to be focused and protected.
As shown in FIG. 5, the operation of sheathing thewire harness 200 composed of a plurality of wires with the sheathing material 1 is performed by first extending the wire of the wire harness 200 from the opening facing the vertical wall 3 a with respect to the second member 3. The wire harness 200 is inserted into the interior of the long second member 3 in a direction perpendicular to the direction. Next, the first member 2 is externally fitted and combined with the second member 3 to form a square cylinder, and the upper and lower walls 2b and 3b that vertically overlap the opposing vertical walls 2a and 3a of the first and second members 2 and 3; The lower wall 2c and 3c surround the electric wire group of the wire harness 200.
図5に示すように、外装材1で複数の電線からなるワイヤハーネス200を外装する作業は、まず、第2部材3に対して縦壁3aと対向する開口からワイヤハーネス200の電線を長さ方向に対して直交方向から横入れして、長尺な第2部材3の内部にワイヤハーネス200を挿通する。ついで、該第2部材3に第1部材2を外嵌して組み合わせ、四角筒とし、第1、第2部材2、3の対向する縦壁2a、3aと上下に重なる上壁2bと3bおよび下壁2cと3cでワイヤハーネス200の電線群を囲む。 The
As shown in FIG. 5, the operation of sheathing the
図5(B)に示すように、第1部材2と第2部材3は長さ方向Xの両端を引き出されるワイヤハーネス200の電線群と共に粘着テープ30を巻き付けてテープ巻き固着している。これにより、四角筒に組み立てた第1部材2と第2部材3とを連結固着すると共に、該第1、第2部材2、3とワイヤハーネス200の電線群も固着している。
As shown in FIG. 5 (B), the first member 2 and the second member 3 are fixed by winding the adhesive tape 30 together with the wire group of the wire harness 200 drawn out at both ends in the length direction X. As a result, the first member 2 and the second member 3 assembled in the square tube are connected and fixed, and the first and second members 2 and 3 and the wire group of the wire harness 200 are also fixed.
即ち、長さ方向の両端を除く部分では、第1部材2と第2部材3とはテープ巻き等で連結固着しておらず、前記切り込み2d、2e、3d、3eにより長さ方向Xに上壁を分割片2f、3fで構成し、縦壁を分割片2g、3gで構成している。第1部材2と第2部材3とは下壁2c、3cを重ねた状態で、図1(C)、図2(B)、図6(B)に拡大して示すように、第1部材2の下壁2cのヒンジ部2hと上壁2bの切り込み2eとは上下対向するが、上壁2bの切り込み2eと第2部材3の下壁3cのヒンジ部3h1、3h2は長さ方向に千鳥配置となる。
That is, in the portion excluding both ends in the length direction, the first member 2 and the second member 3 are not connected and fixed by tape winding or the like, and are moved upward in the length direction X by the notches 2d, 2e, 3d, and 3e. The wall is constituted by divided pieces 2f and 3f, and the vertical wall is constituted by divided pieces 2g and 3g. The first member 2 and the second member 3 are in a state where the lower walls 2c and 3c are overlapped, as shown in an enlarged view in FIGS. 1 (C), 2 (B), and 6 (B). 2, the notch 2e of the lower wall 2c and the notch 2e of the upper wall 2b are vertically opposed, but the notch 2e of the upper wall 2b and the hinges 3h1, 3h2 of the lower wall 3c of the second member 3 are staggered in the length direction. Arrangement.
前記構成とし、上壁を分割片3f、2fを千鳥配置で上下に重ね、対向する左右縦壁を分割片2g、3gで構成する。下壁は分割片3i、2iを千鳥配置で上下に重ねると共に分割片2iの間のヒンジ部2hと分割片3iの間のヒンジ部3h1、突出部3j、ヒンジ部3h2を千鳥配置している。
The above structure is adopted, and the upper wall is divided into upper and lower divided pieces 3f and 2f in a staggered arrangement, and the opposite left and right vertical walls are constituted by divided pieces 2g and 3g. In the lower wall, the divided pieces 3i and 2i are stacked in a staggered manner, and the hinge portion 2h between the divided pieces 2i and the hinge portion 3h1, the protruding portion 3j, and the hinge portion 3h2 between the divided pieces 3i are arranged in a staggered manner.
前記のように組み立てる外装材1は、外周側の上面となる第1部材2の上壁2bの切り込み2eに下側から第2部材3の段状突起3kを挿入して嵌合することで、切り込み2eにより分割片2fの間に隙間は発生せず、外装材1の上面は図1(A)および図2(A)に示すように直線に保持できる。
The exterior material 1 to be assembled as described above is fitted by inserting the stepped protrusion 3k of the second member 3 from below into the notch 2e of the upper wall 2b of the first member 2 which is the upper surface on the outer peripheral side, A gap is not generated between the divided pieces 2f due to the notches 2e, and the upper surface of the exterior material 1 can be held in a straight line as shown in FIGS. 1 (A) and 2 (A).
一方、図1(B)、図2(C)に示すように上壁2b、3bを外周とすると共に下壁2c、3cを内周として屈曲できる。即ち、上壁2bの切り込み2e、上壁3bの切り込み3eが開き、隣接する分割片2fと2fの間、分割片3fと3fの間が広がる。この状態で、上面側の分割片2fと2fの間の中央に段状突起3kが位置すると共に、段状突起3kを挟んで分割片3fの両側上面が位置し、隣接する分割片2fと2fの間の拡がった切り込み2eを下側の第2部材3の上壁3bの分割片3fで塞ぎ、外周側に空隙を発生させない。かつ、下壁2cはヒンジ部2hの変形許容で若干曲がることができるが、上壁側で段状突起3kが切り込み2eの間に挟み込まれているために屈曲できず、上向きには曲がらず、外装材1の屈曲方向は一方向に規制される。
On the other hand, as shown in FIGS. 1B and 2C, the upper walls 2b and 3b can be bent as the outer periphery and the lower walls 2c and 3c can be bent as the inner periphery. That is, the notch 2e of the upper wall 2b and the notch 3e of the upper wall 3b are opened, and the space between the adjacent divided pieces 2f and 2f and the space between the divided pieces 3f and 3f are widened. In this state, the stepped protrusion 3k is located at the center between the upper divided pieces 2f and 2f, and the upper surfaces on both sides of the divided piece 3f are located across the stepped protrusion 3k, and the adjacent divided pieces 2f and 2f are located. The notch 2e that is widened between them is closed by the divided piece 3f of the upper wall 3b of the lower second member 3, so that no gap is generated on the outer peripheral side. And although the lower wall 2c can be bent slightly due to the deformation allowance of the hinge portion 2h, the stepped protrusion 3k is sandwiched between the cuts 2e on the upper wall side, so that it cannot be bent and does not bend upward. The bending direction of the exterior material 1 is restricted to one direction.
前記図1(B)、図2(C)に示すように屈曲する際、第1部材2の下壁2cにヒンジ部2hを設けると共に、第2部材3の下壁3cにヒンジ部3h1、3h2を設けているため、第1、第2部材2、3はヒンジ部が無い従来例と比較して屈曲しやすくなる。このように、下壁2cと3cからなる内周側の屈曲時の曲率を小さくできるため、縦壁2a、3aで連続する上壁2b、3bからなる外周側の曲率も小さくなる。このように、外装材1自体の曲率を小さくできるため、図7に示すように、外装材1を横向きU字状に配置した状態で上下高さHを低くできる。
When bending as shown in FIGS. 1B and 2C, the hinge 2h is provided on the lower wall 2c of the first member 2, and the hinges 3h1, 3h2 are provided on the lower wall 3c of the second member 3. Therefore, the first and second members 2 and 3 are easily bent as compared with the conventional example having no hinge portion. Thus, since the curvature at the time of bending of the inner peripheral side consisting of the lower walls 2c and 3c can be reduced, the curvature of the outer peripheral side consisting of the upper walls 2b and 3b continuous with the vertical walls 2a and 3a is also reduced. Thus, since the curvature of exterior material 1 itself can be made small, as shown in FIG. 7, vertical height H can be made low in the state which arranged exterior material 1 in the horizontal U shape.
かつ、図6(B)に示すように、屈曲時に第2部材3の下壁3cでは分割片3iの間に2つのヒンジ部3h1、3h2を突出部3jを挟んで2点設けているため、曲げ角度を吸収できる。第2部材3の下壁3cの分割片3iの曲げアールR1と、下側に重ねる第1部材2の下壁2cの分割片2iの曲げアールR2の周差を小さくできる。
In addition, as shown in FIG. 6B, since the lower wall 3c of the second member 3 is provided with two hinge portions 3h1, 3h2 between the split pieces 3i with the protruding portion 3j interposed therebetween when bent, The bending angle can be absorbed. The circumferential difference between the bending radius R1 of the divided piece 3i of the lower wall 3c of the second member 3 and the bending radius R2 of the divided piece 2i of the lower wall 2c of the first member 2 stacked on the lower side can be reduced.

かつ、外装材1の外周側と内周側のいずれも屈曲しやすくしているため、前記のように、横向きU字状に配索する外装材の上下高さHを低くできる。 Following the back-and-forth movement of theslide sheet 150, the upper surface of the wire harness 200 covered with the exterior material 1 moves in the front-rear direction (arrow FR) along the lower surface of the passenger compartment floor material 170, and the lower surface of the wire harness 200 is the floor It moves along the panel 160 in the front-rear direction.
In addition, since both the outer peripheral side and the inner peripheral side of theouter packaging material 1 are easily bent, the vertical height H of the outer packaging material arranged in a lateral U-shape can be lowered as described above.
