Description

ワイヤハーネス用の外装材Exterior material for wire harness

　本発明はワイヤハーネス用の外装材に関し、詳しくは、キャタピラ型の外装材を改良するものである。 The present invention relates to an outer packaging material for a wire harness, and more specifically, an improvement of a caterpillar type outer packaging material.

　従来、自動車等の車両に配索するワイヤハーネスの電線群は、コルゲートチューブ、プロテクタ等の外装材で外装し、あるいは粘着テープを巻き付けて集束保護している。ワイヤハーネスがスライドシート、スライドドア等に配索され、シートやドアの移動に応じてワイヤハーネスも移動する場合、該ワイヤハーネスの全長を屈曲および伸縮が可能なコルゲートチューブで外装している場合が多い。
　前記コルゲートチューブを外装材として用いると、コルゲートチューブは全周のいずれの方向にも屈曲できるため、屈曲方向の規制ができず、周辺機器と接触する恐れがある。　さらに、配索スペースが断面四角形状であると、丸型のコルゲートチューブで外装したワイヤハーネスを通すと、配索スペースに挿通できるワイヤハーネスの電線本数が減少し、配索スペースを有効利用できない問題がある。 Conventionally, an electric wire group of a wire harness that is routed in a vehicle such as an automobile is externally covered with an external material such as a corrugated tube or a protector, or is wrapped and protected with an adhesive tape. When a wire harness is routed to a slide seat, a slide door, etc., and the wire harness moves as the seat or door moves, the entire length of the wire harness may be covered with a corrugated tube that can be bent and expanded. Many.
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 the exterior 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 the exterior 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.

特開２０１３－４９４０２号公報JP 2013-49402 A

　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 the exterior 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 the exterior 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.

　前記課題を解決するため、本発明は、ワイヤハーネスに外装するキャタピラ型の外装材であって、
　縦壁の上下両端に上壁と下壁を連続させた断面コ字形状の第１部材と第２部材を備え、　前記第１部材および第２部材の縦壁の下端から上壁の先端にかけてＬ字状に連続する切り込みを長さ方向に間隔をあけて設け、かつ、前記第１部材および第２部材の下壁には前記上壁の切り込みと対向した位置に薄肉のヒンジ部を設け、前記第１部材および第２部材の下壁は各ヒンジ部を挟む両側片を屈曲自在に連結しており、
前記第１部材と第２部材の縦壁同士を対向配置し、該第１部材の上壁の下面を前記第２部材の上壁に載せると共に、前記第１部材の下壁の上面に前記第２部材の下壁を載せて該第１、第２部材とで四角筒状に組み立てる構成とすることを特徴とするワイヤハーネス用の外装材を提供している。 In order to solve the above-mentioned problem, the present invention is a caterpillar type exterior material to be sheathed on a wire harness,
A first member and a second member having a U-shaped cross section in which an upper wall and a lower wall are continuous at both upper and lower ends of the vertical wall, and L extending from the lower end of the vertical wall of the first member and the second member to the tip of the upper wall. Incisions that are continuous in a letter shape are provided at intervals in the length direction, and a thin-walled hinge portion is provided on the lower wall of the first member and the second member at a position facing the notches of the upper wall, The lower walls of the first member and the second member connect both side pieces sandwiching each hinge portion so as to be freely bent,
The vertical walls of the first member and the second member are opposed to each other, the lower surface of the upper wall of the first member is placed on the upper wall of the second member, and the upper surface of the lower wall of the first member is An exterior material for a wire harness is provided in which a lower wall of two members is placed and the first and second members are assembled into a rectangular tube shape.

　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. The upper wall and the left and right vertical walls are divided by cutting in a state where a square cylinder is combined, but the lower wall is connected by a hinge portion, so the caterpillar type exterior material presented in Patent Document 1 and Similarly, the upper wall can be bent on the outer peripheral side, but the lower wall on the inner peripheral side cannot be bent, and a caterpillar-type exterior material that can regulate the bending direction can be obtained.
In this way, the lower walls of the first and second members are not flat, but are provided with hinge portions spaced apart in the length direction, so that they can be bent easily like the upper wall, When the lower wall is the inner circumference, the inner and outer circumference difference is reduced, the lower wall on the inner circumference side is easily bent when bent, the curvature of the entire exterior material can be reduced when bent, and the arrangement space can be reduced. And it can suppress that the notch of the upper wall used as an outer peripheral side spreads widely.

　前記第１部材の上壁の前記切り込みに挟まれた分割片の下面中央に下向きの段状突起を設けると共に、前記第２部材の上壁の前記切り込みに挟まれた分割片の上面中央に上向きの段状突起を設け、
　前記第１、第２部材の縦壁の前記切り込みを対向させずに長さ方向に交互に千鳥配置で位置させ、前記第１部材の上壁の前記切り込みに前記第２部材の上壁の前記段状突起を嵌合させて前記切り込みが開いて発生する隙間を前記第２部材の上壁で塞ぐようにし、かつ、前記第１部材の上壁の下向きの前記段状突起を第２部材の上壁の前記切り込みに嵌合させる構成としている。 A downward stepped projection is provided at the center of the lower surface of the split piece sandwiched between the cuts in the upper wall of the first member, and upwards to the center of the upper surface of the split piece sandwiched between the cuts in the upper wall of the second member. Stepped projections of
The notches of the vertical walls of the first and second members are positioned in a staggered arrangement alternately in the length direction without facing each other, and the notches of the upper wall of the second member are placed in the notches of the upper wall of the first member. A stepped protrusion is fitted to close the gap generated by the opening of the notch with the upper wall of the second member, and the stepped protrusion downward of the upper wall of the first member is connected to the second member. 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.

　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).

　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。 The exterior 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 the wire 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（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.

　前記外装材１で外装したワイヤハーネス２００を、図７（Ａ）に示すように、自動車に搭載するスライドシート１５０に配索する場合に好適に用いられる。
　前記ワイヤハーネス２００はフロアハーネスの幹線から分岐するワイヤハーネスで、該ワイヤハーネス２００の先端をスライドシート１５０の下面に固定し、車室床材１７０の下方で前後方向に直線状に配索した後に後端側で下向きに屈曲し、再度、前方へ直線状に配索し、横向きＵ形状に配索して、フロアパネル１６０に固定している。 As shown in FIG. 7A, the wire harness 200 sheathed with the exterior material 1 is suitably used when being routed on a slide sheet 150 mounted on an automobile.
The wire harness 200 is a wire harness that branches off from the trunk line of the floor harness. After the front end of the wire harness 200 is fixed to the lower surface of the slide seat 150 and routed linearly in the front-rear direction below the vehicle floor material 170. It bends downward at the rear end side, is routed linearly forward again, is routed in a lateral U shape, and is fixed to the floor panel 160.

　スライドシート１５０の前後移動に追従して、外装材１で外装したワイヤハーネス２００の上面は車室床材１７０の下面に沿って前後方向（矢印ＦＲ）に移動し、ワイヤハーネス２００の下面はフロアパネル１６０に沿って前後方向に移動する。
　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 the slide 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 the outer 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.

　本発明の外装材１は前記スライドシートに配索するワイヤハーネスの外装材に限定されず、他の箇所に屈曲自在に配索されるワイヤハーネスの外装材としても好適に利用できる。 The exterior material 1 of the present invention is not limited to the exterior material of a wire harness that is routed on the slide sheet, and can be suitably used as an exterior material of a wire harness that is flexibly routed to other locations.
