Description

本発明はワイヤハーネスの配索構造に関し、詳しくは、自動車に搭載されるスライドシート用として好適に用いられ、ワイヤハーネスをキャタピラ型の外装材で外装して余長吸収ケース内に移動自在に収容すると共に、該余長吸収ケースの出口で固定するワイヤハーネスの配索構造に関するものである。   The present invention relates to a wiring structure of a wire harness, and more specifically, is suitably used for a slide seat mounted on an automobile, and is externally accommodated by a caterpillar-type exterior material and movably accommodated in an extra length absorption case. In addition, the present invention relates to a wiring structure of a wire harness that is fixed at the outlet of the extra length absorption case.

自動車に搭載するシートには電動リクライニング装置やシートヒータなど種々の電装品が装備されており、これらの電装品に給電するために、車体フロア側からシートに給電用のワイヤハーネスが配索されている。スライドシートの場合には、ワイヤハーネスをシートのスライド動作に追従させる必要があり、そのためワイヤハーネスに余長部を持たせて配索している。   The seats mounted on automobiles are equipped with various electrical components such as electric reclining devices and seat heaters. In order to supply power to these electrical components, a power supply wire harness is routed from the vehicle body floor to the seat. Yes. In the case of a slide sheet, it is necessary to cause the wire harness to follow the sliding motion of the sheet. For this reason, the wire harness is provided with an extra length portion.

従来、本出願人は特開2013−49402号公報において、図10に示すように、ワイヤハーネス100をキャタピラ型のプロテクタ110で外装して、余長吸収ケース内に移動自在に収容しているワイヤハーネス配索構造を提供している。
前記配索構造では、ワイヤハーネス100を挿通したプロテクタ110を余長吸収ケースの出口から引き出し、この引き出したワイヤハーネス100にクランプを取り付け、該クランプを車体フロアに固定している。
Conventionally, in Japanese Patent Application Laid-Open No. 2013-49402, the applicant of the present invention has a wire harness 100 that is externally covered with a caterpillar type protector 110 and is movably accommodated in a surplus length absorbing case as shown in FIG. A harness routing structure is provided.
In the routing structure, the protector 110 through which the wire harness 100 is inserted is pulled out from the outlet of the surplus length absorbing case, a clamp is attached to the pulled out wire harness 100, and the clamp is fixed to the vehicle body floor.

前記フロアにワイヤハーネスに取り付けたクランプを用いて固定する方法に代えて、図11に示すように、余長吸収ケース120の出口にテープ巻き片121を設け、粘着テープ130を用いて固着している場合が多い。具体的には、余長吸収ケース120の出口先端にワイヤハーネスに外装するプロテクタ110の出口110pを合わせ、余長吸収ケース120の出口を囲む外周に粘着テープ130を巻き付けた後に、該プロテクタ110の出口先端から引き出されるワイヤハーネス100とテープ巻き片121とに粘着テープ130を巻き付け、粘着テープ130を所謂テープ巻き落とし処理して連続的に巻き付けて固着している場合が多い。   Instead of using a clamp attached to the wire harness to the floor, as shown in FIG. 11, a tape winding piece 121 is provided at the outlet of the extra length absorption case 120 and fixed using an adhesive tape 130. There are many cases. Specifically, the outlet 110p of the protector 110 that is externally mounted on the wire harness is aligned with the outlet end of the surplus length absorbing case 120, and the adhesive tape 130 is wound around the outer periphery surrounding the outlet of the surplus length absorbing case 120. In many cases, the adhesive tape 130 is wound around the wire harness 100 and the tape winding piece 121 drawn from the tip of the outlet, and the adhesive tape 130 is continuously wound by a so-called tape winding process.

なお、前記図11に示す例では、余長吸収ケース120をフロアに固定しているため、余長吸収ケース内に移動自在に挿通するワイヤハーネス100に外装したキャタピラ型のプロテクタ110を余長吸収ケース120の出口側で固定している。これに対して、余長吸収ケースをスライドシートに固定している場合、該余長吸収ケースの入口側でワイヤハーネスに外装したキャタピラ型のプロテクタを固定している。
即ち、キャタピラ型のプロテクタにワイヤハーネスを挿通した状態で、余長吸収ケースの出口または入口のいずれか一方にプロテクタとワイヤハーネスとを固定している。
In the example shown in FIG. 11, the extra length absorbing case 120 is fixed to the floor, so that the caterpillar type protector 110 sheathed on the wire harness 100 that is movably inserted into the extra length absorbing case is absorbed. It is fixed on the outlet side of the case 120. On the other hand, when the surplus length absorption case is fixed to the slide sheet, a caterpillar type protector sheathed on the wire harness is fixed on the inlet side of the surplus length absorption case.
That is, with the wire harness inserted through the caterpillar type protector, the protector and the wire harness are fixed to either the outlet or the inlet of the surplus length absorbing case.

特開2013−49402号公報JP 2013-49402 A

前記のように、キャタピラ型のプロテクタと、該プロテクタに挿通したワイヤハーネスとを余長吸収ケースの出口または入口に突設したテープ巻き片にテープ巻き固定する場合、図11(B)に示すように、四角枠状のプロテクタ110の先端に巻き付けた粘着テープ130を外径が小さくなる断面円形のワイヤハーネス100の外周に巻き落とし処理して巻き付ける必要がある。   As shown in FIG. 11B, when the caterpillar type protector and the wire harness inserted through the protector are taped and fixed to the tape wound piece protruding from the outlet or entrance of the extra length absorption case, as shown in FIG. In addition, it is necessary to wind down the adhesive tape 130 wound around the tip of the square frame-shaped protector 110 around the outer periphery of the wire harness 100 having a circular cross section with a small outer diameter.

この巻き落とし処理時に、プロテクタ110の外周に強い力で粘着テープ130が巻き付けられてプロテクタ110の外形が四角枠状から潰れ、テープ巻き作業に手数がかかると共に品質が低下する恐れがある。かつ、粘着テープ130で連続してプロテクタ110の外周からワイヤハーネス100の外周に巻き落とし処理して巻き付けると、プロテクタ110は余長吸収ケース120の外周面に拘束される。一方、ワイヤハーネス100は余長吸収ケース120の外周面に拘束されず、プロテクタ110内でワイヤハーネス100の軌道が図12に示すように、プロテクタ110の外周面に沿って大きな曲げRで曲がらずに、曲げRが小さくなり屈曲性が悪くなる問題がある。   During the winding process, the adhesive tape 130 is wound around the outer periphery of the protector 110 with a strong force, and the outer shape of the protector 110 is crushed from the rectangular frame shape. And if it winds down and winds around the outer periphery of the wire harness 100 from the outer periphery of the protector 110 continuously with the adhesive tape 130, the protector 110 will be restrained by the outer peripheral surface of the surplus length absorption case 120. On the other hand, the wire harness 100 is not constrained by the outer peripheral surface of the extra length absorbing case 120, and the track of the wire harness 100 is not bent by the large bend R along the outer peripheral surface of the protector 110 in the protector 110 as shown in FIG. In addition, there is a problem in that the bending R becomes small and the flexibility becomes poor.

本発明は前記問題に鑑みてなされたもので、余長吸収ケース内にキャタピラ型外装材でワイヤハーネスを外装して貫通しているワイヤハーネスの配索構造において、前記余長吸収ケースの出口または入口に、前記キャタピラ型外装材とワイヤハーネスを余長吸収ケース内での屈曲性を損なうことなくスムーズに固定できるようにすることを課題としている。   The present invention has been made in view of the above problem, and in the wiring structure of a wire harness that is externally penetrated by a caterpillar type exterior material in the surplus length absorption case, the outlet of the surplus length absorption case or It is an object of the present invention to enable the caterpillar type exterior material and the wire harness to be smoothly fixed to the entrance without impairing the flexibility in the extra length absorption case.

前記課題を解決するため、本発明は、自動車のスライドシート用のワイヤハーネスをキャタピラ型外装材に挿通した状態で余長吸収ケース内に屈曲させて移動自在に挿通し、該余長吸収ケースの1つの出入口の四角枠状の先端開口の外周側面又は底面外周寄りから段差をつけてテープ巻き片を突設し、該テープ巻き片に前記キャタピラ型外装材の先端から引き出された前記ワイヤハーネスを粘着テープで巻き付けて固着し、かつ、
前記テープ巻き片を突設した前記出入口を囲む周壁を、断面凹形状の本体と、該本体に薄肉ヒンジを介して片開き状に連結して該本体の上面開口を開閉する蓋とで形成し、該蓋又は前記本体の底面に設けた係止突起を前記キャタピラ型外装材に開口している穴に差し込んで固定する構成としているワイヤハーネスの配索構造を提供している。
In order to solve the above-mentioned problems, the present invention provides a wire harness for a slide seat of an automobile inserted into a caterpillar type exterior material, bent in an excess length absorption case, and movably inserted. A tape winding piece is provided with a step from the outer peripheral side or bottom outer periphery of the square frame-shaped tip opening of one doorway, and the wire harness drawn out from the tip of the caterpillar type exterior material is attached to the tape winding piece. Wound with adhesive tape and fixed, and
A peripheral wall surrounding the entrance and exit from which the tape winding piece is projected is formed by a main body having a concave cross section and a lid that opens and closes the upper surface opening of the main body by connecting to the main body through a thin hinge. A wiring harness wiring structure is provided in which a locking projection provided on the bottom surface of the lid or the main body is inserted into a hole opened in the caterpillar type exterior member and fixed.

前記のように、余長吸収ケースのワイヤハーネス出入口となる長さ方向両端の開口のうちの一方のテープ巻き片を突設した開口を囲む周壁を断面凹形状の本体と蓋とから構成し、該蓋の内面または本体の底面から係止突起を突設し、ワイヤハーネスを挿通しているキャタピラ型外装材の穴に差し込んで簡単に固定できるようにしている。かつ、該キャタピラ型外装材の固定とは別に、余長吸収ケースの外周側に突設した前記テープ巻き片にワイヤハーネスを粘着テープで巻き付けて固着しているため、ワイヤハーネスを余長吸収ケースの外周側に拘束することができる。これにより、該余長吸収ケース内で外周壁に沿って移動する前記キャタピラ型外装材の内部で、ワイヤハーネスを外周側に沿わせて曲げRを大きい状態に保持でき、ワイヤハーネスの屈曲性を向上させることができる。   As described above, the peripheral wall surrounding the opening projecting one tape winding piece of the opening at both ends in the length direction serving as the wire harness entrance / exit of the surplus length absorption case is constituted by a body having a concave cross section and a lid, Locking projections are provided so as to project from the inner surface of the lid or the bottom surface of the main body, and can be easily fixed by being inserted into holes in the caterpillar type exterior material through which the wire harness is inserted. In addition to fixing the caterpillar type exterior material, the wire harness is secured to the tape winding piece protruding from the outer peripheral side of the extra length absorption case by winding the wire harness with an adhesive tape. It can restrain to the outer peripheral side. As a result, inside the caterpillar-type exterior material that moves along the outer peripheral wall within the extra length absorption case, the wire harness can be held in a large state along the outer peripheral side, and the flexibility of the wire harness can be increased. Can be improved.

前記キャタピラ型外装材は、長さ方向に延在すると共に幅方向に間隔をあけて設けた複数本の折曲ラインを折り曲げて四角筒型とし、かつ、長さ方向に間隔をあけて幅方向に切り込みを入れて四角筒型の3辺を分離させると共に1辺を連続させ、前記一方側は屈曲するが他方側は屈曲しない状態で連結し、かつ、幅方向の両側縁の一方側に突設した係止突片を他方側に設けた係止穴に挿入係止して四角筒状を保持し、さらに、前記幅方向の各切り込みの先端に亀裂防止用の穴をあけており、該穴を前記余長吸収ケースの蓋または本体底面に突設した前記係止突起を差し込む穴としている。   The caterpillar type exterior material extends in the length direction and bends a plurality of folding lines provided at intervals in the width direction to form a rectangular tube shape, and the width direction at intervals in the length direction. The three sides of the rectangular tube type are separated and one side is continuous, and the one side is bent but the other side is not bent, and is connected to one side of both side edges in the width direction. The locking projection piece provided is inserted and locked into a locking hole provided on the other side to hold the square tube shape, and further, a crack prevention hole is formed at the tip of each cut in the width direction, The hole is a hole into which the locking protrusion protruding from the lid or the bottom of the main body is inserted.

前記ワイヤハーネス3をキャタピラ型外装材5(以下、外装材5と略称する)で外装し、前記シートレール2の側部に隣接した位置の車室床材Fの下部に固定する余長吸収ケース6内に挿通している。余長吸収ケース6は図2に示すように、倒J字形状として垂直配置し、上方に長尺な直線部6aを位置させ、前端を湾曲部6bとし、下方に短尺な直線部6cを位置させている。下方の直線部6cの先端を余長吸収ケース6の出入口6iとし、フロアハーネス50から分岐したワイヤハーネス3を出入口6iを通して余長吸収ケース6内をJ形状に迂回させた状態で移動自在に挿通している。ワイヤハーネス3は余長吸収ケース6の上方の直線部6aに前後直線方向に設けたスライダ嵌合溝6e(図3に示す)に摺動自在に嵌合しているスライダ8を通して上方のスライドシート1側へ引き出し、シートハーネス55とコネクタ接続している。   A surplus length absorption case for covering the wire harness 3 with a caterpillar-type exterior material 5 (hereinafter abbreviated as an exterior material 5) and fixing the wire harness 3 to a lower portion of the passenger compartment floor material F adjacent to the side portion of the seat rail 2 6 is inserted through. As shown in FIG. 2, the surplus length absorbing case 6 is vertically arranged as an inverted J shape, with the long straight portion 6a positioned above, the front end as the curved portion 6b, and the short straight portion 6c positioned below. I am letting. The tip of the lower straight line portion 6c is used as the entrance / exit 6i of the surplus length absorption case 6, and the wire harness 3 branched from the floor harness 50 is movably inserted through the entrance / exit 6i while diverting the surplus length absorption case 6 into a J shape. doing. The wire harness 3 moves upward through a slider 8 that is slidably fitted in a slider fitting groove 6e (shown in FIG. 3) that is provided in a linear direction in the front-rear direction in the straight portion 6a above the surplus length absorbing case 6. It is pulled out to the 1 side and connected to the seat harness 55 through a connector.

前記構成として、スライドシート1の移動にワイヤハーネス3が連動すると、該ワイヤハーネス3の移動にスライダ8および外装材5が連動し、該スライダ8を余長吸収ケース6のスライダ嵌合溝6e内を移動させている。   As described above, when the wire harness 3 is interlocked with the movement of the slide sheet 1, the slider 8 and the exterior member 5 are interlocked with the movement of the wire harness 3, and the slider 8 is placed in the slider fitting groove 6 e of the extra length absorbing case 6. Is moving.

前記余長吸収ケース6の出入口6iに、後述するように、外装材5とワイヤハーネス3とを別々の固定手段で固定している。よって、スライドシート1が前後移動するとシートハーネス55と接続しているワイヤハーネス3も追従して前後移動し、該ワイヤハーネス3と連動してスライダ8が余長吸収ケース6のスライダ嵌合溝6e内を前後方向に移動する。このスライダ8の移動により、外装材5で外装したワイヤハーネス3は余長吸収ケース6内でJ形状の湾曲部を前後に移動させて追従させるものとしている。   As will be described later, the exterior material 5 and the wire harness 3 are fixed to the entrance 6i of the extra length absorption case 6 by separate fixing means. Therefore, when the slide seat 1 moves back and forth, the wire harness 3 connected to the seat harness 55 also follows and moves back and forth, and the slider 8 moves in conjunction with the wire harness 3 and the slider fitting groove 6e of the extra length absorbing case 6 moves. Move in the front-back direction. The movement of the slider 8 causes the wire harness 3 sheathed with the sheathing material 5 to move the J-shaped curved portion back and forth within the extra length absorption case 6 to follow.

前記倒J形状とした余長吸収ケース6は図3に示すように、比較的浅底の本体60と外装材5で外装したワイヤハーネス3を挿通した後に本体60に被せる蓋61とからなる。本体60はJ形状とした底面60aの外周縁に沿って外周壁60bを設け、内周縁に沿って内周壁60cを設けている。蓋61は前記出入口6iを囲む部分を除いて本体60の外周壁60bと内周壁60cの突出端に当接させて閉鎖し、ロック結合して取り付けるものとしている。   As shown in FIG. 3, the extra-length absorption case 6 having the inverted J shape includes a relatively shallow main body 60 and a lid 61 that covers the main body 60 after the wire harness 3 sheathed with the exterior material 5 is inserted. The main body 60 has an outer peripheral wall 60b along the outer peripheral edge of the J-shaped bottom surface 60a, and an inner peripheral wall 60c along the inner peripheral edge. The lid 61 is closed by contacting the projecting ends of the outer peripheral wall 60b and the inner peripheral wall 60c of the main body 60 except for the portion surrounding the entrance / exit 6i, and is attached by locking.

余長吸収ケース6の出入口6iでは、本体60の外周壁60bの先端から薄肉ヒンジ62を介して蓋63を一体的に設け、該蓋63の裏面に所要間隔をあけて2つの係止突起10を突設している。かつ、蓋63の先端にロック爪63rを設け、該ロック爪63rが挿入係止するロック枠60rを内周壁60cの外面に設けている。蓋63を本体60に被せてロック結合すると、その内部に挿通させる前記外装材5に設けられている穴11に係止突起10が差し込まれ、外装材5が余長吸収ケース6に固定されるようにしている。前記2つの係止突起10は比較的短い棒状とし、外装材5の上面の穴11に差し込まれた状態で、外装材5内に通すワイヤハーネス3の電線群の邪魔にならないようにしている。   At the entrance / exit 6i of the surplus length absorption case 6, a lid 63 is integrally provided from the front end of the outer peripheral wall 60b of the main body 60 via a thin hinge 62, and two locking projections 10 are provided on the back surface of the lid 63 with a required interval. Is protruding. A lock claw 63r is provided at the tip of the lid 63, and a lock frame 60r into which the lock claw 63r is inserted and locked is provided on the outer surface of the inner peripheral wall 60c. When the lid 63 is put on the main body 60 and locked, the locking projection 10 is inserted into the hole 11 provided in the exterior material 5 that is inserted through the lid 63, and the exterior material 5 is fixed to the extra length absorbing case 6. I am doing so. The two locking projections 10 are formed in a relatively short rod shape so as not to obstruct the electric wire group of the wire harness 3 that passes through the exterior material 5 when inserted into the hole 11 on the upper surface of the exterior material 5.

さらに、出入口6iには、本体60の外周側寄りにテープ巻き片12を突設している。該テープ巻き片12に外装材5の先端より引き出されるワイヤハーネス3を粘着テープ15で巻き付け、ワイヤハーネス3を余長吸収ケース6に固定するようにしている。かつ、図3(C)に示すように、テープ巻き片12は外装材5の肉厚t1だけ本体60の外周壁60bの内面より段差をつけて突設している。これにより、外装材5から引き出されるワイヤハーネス3にテープ巻き片12をぴったりと沿わせて巻き付けることが出来るようにしている。   Furthermore, a tape winding piece 12 projects from the entrance / exit 6i toward the outer peripheral side of the main body 60. The wire harness 3 drawn out from the front end of the exterior member 5 is wound around the tape winding piece 12 with an adhesive tape 15, and the wire harness 3 is fixed to the extra length absorbing case 6. Further, as shown in FIG. 3C, the tape wound piece 12 protrudes from the inner surface of the outer peripheral wall 60b of the main body 60 by a thickness t1 of the exterior material 5 with a step. As a result, the tape winding piece 12 can be tightly wound around the wire harness 3 drawn from the exterior member 5.

なお、余長吸収ケース6の本体60に全体の蓋61を薄肉ヒンジを介して連結し、出入口6iの部分で蓋61にスリットを入れて独立して開閉する蓋63を設けてもよい。   In addition, the whole lid | cover 61 may be connected to the main body 60 of the surplus length absorption case 6 via a thin hinge, and the lid | cover 63 which opens and closes independently by putting a slit in the lid | cover 61 in the part of the entrance / exit 6i may be provided.

外装材5は、図4(A)に示す四角筒状のキャタピラ型としている。該外装材5は図4(B)に示す樹脂製の帯状に連続した長尺材からなる平板40を折り曲げて組み立てている。平板40には、長さ方向Xに延在する4本の折曲ライン41、42、43、44を幅方向Yの中間部に間隔をあけて設け、平板40を幅方向に5個の辺S1〜S5に区画している。折曲ライン41〜44を直角に折り曲げ、幅方向の両側辺S1とS5を突き合わせて先端部分を重ねることで図4(A)に示すように、四角筒状に組み立てている。   The exterior material 5 is a square cylindrical caterpillar type shown in FIG. The exterior material 5 is assembled by bending a flat plate 40 made of a long material continuous in the shape of a resin band shown in FIG. The flat plate 40 is provided with four bent lines 41, 42, 43, 44 extending in the length direction X at intervals in the middle portion in the width direction Y, and the flat plate 40 is provided with five sides in the width direction. It is divided into S1 to S5. As shown in FIG. 4 (A), the folding lines 41 to 44 are folded at right angles, the side portions S1 and S5 in the width direction are brought into contact with each other, and the tip portions are overlapped to form a rectangular tube shape.

また、平板40の幅方向の一方側の辺S1の側縁に係止突片45を長さ方向Xに間隔をあけて突設している。平板40の他方側の辺S5に係止突片45を挿入係止する細長い係止穴46を設けている。平板40を折曲ライン41〜44に沿って折り曲げ、辺S1とS5の一部を重ねた状態で係止突片45を係止穴46に挿入係止することで、四角筒形状を保持できるようにしている。   Further, a locking protrusion 45 is provided on the side edge of one side S <b> 1 in the width direction of the flat plate 40 with a gap in the length direction X. An elongated locking hole 46 for inserting and locking the locking protrusion 45 is provided in the other side S5 of the flat plate 40. The rectangular tube shape can be maintained by bending the flat plate 40 along the folding lines 41 to 44 and inserting and locking the locking protrusions 45 into the locking holes 46 with the sides S1 and S5 partially overlapped. I am doing so.

平板40には前記折曲ライン41に近接した位置から折り曲げライン42、43を通り、折曲ライン44に近接した位置まで幅方向Yの切込ライン48を長さ方向Xに間隔をあけて設け、辺S2、S3、S4を分離している。さらに、切込ライン48の中央部の辺S3の中央位置に直線を湾曲させた円弧状の切込49を設け、長さ方向に隣接する一方側を円弧状に突出させ、他方を円弧状に窪ませ、凹凸嵌合部を設けている。   The flat plate 40 is provided with a cut line 48 in the width direction Y spaced from the position close to the bending line 41 through the bending lines 42 and 43 to the position close to the bending line 44 in the length direction X. , Sides S2, S3 and S4 are separated. Further, an arc-shaped cut 49 having a straight line is provided at the center position of the side S3 at the center of the cut line 48, one side adjacent in the length direction is projected in an arc shape, and the other is formed in an arc shape. Recessed and provided with an uneven fitting part.

長さ方向に間隔をあけて設ける幅方向に設ける前記切込ライン48の両端に亀裂が入らないように***からなる前記穴11を設けている。これらの穴11は折曲ライン41、44に近接した位置にあり、外装材5を四角筒状に組み立てた状態で上下面の折曲ライン41、44に沿って穴11が位置する。この穴11を前記係止突起10が差し込まれる穴として利用している。従って、2つの係止突起10を穴11と同じ間隔をあけて設けている。   The holes 11 made of small holes are provided so that cracks do not occur at both ends of the cut line 48 provided in the width direction provided at intervals in the length direction. These holes 11 are in positions close to the folding lines 41 and 44, and the holes 11 are positioned along the bending lines 41 and 44 on the upper and lower surfaces in a state where the exterior material 5 is assembled in a rectangular tube shape. This hole 11 is used as a hole into which the locking projection 10 is inserted. Accordingly, the two locking projections 10 are provided at the same interval as the hole 11.

外装材5は予め折曲ライン41〜44を折り曲げる一方、係止突片45は係止穴46に挿入せずに開いた状態として、ワイヤハーネス3の電線群を折り曲げた外装材5の両側辺S1とS5の間の開口から挿入する。このワイヤハーネス3の電線群の挿入後に辺S1とS5を重ね、係止突片45を係止穴46に挿入係止し、ワイヤハーネス3の電線群を四角筒の中に挿入した状態で外装している。
外装材5は四角筒の3辺S2、S3、S4が切込ライン48で長さ方向で分離され、重ねて係止した辺S1とS5が長さ方向で屈曲自在に連結された構成となり、かつ、分離された辺S3は、隣接する辺S3同士が円弧状切込で凹凸嵌合する状態となる。即ち、短尺な四角筒が屈曲自在に長さ方向に順次連結し、かつ、隣接する四角筒同士を凹凸嵌合させているため幅方向にずれない構成のキャタピラ型の外装材となる。
この四角筒形状としたキャタピラ型の外装材5を用い、余長吸収ケース6内でガタつき無く内嵌して、安定した姿勢で移動させることができるものとしている。
The exterior material 5 is bent in advance on the folding lines 41 to 44, while the locking protrusions 45 are opened without being inserted into the locking holes 46, and both sides of the exterior material 5 in which the wire group of the wire harness 3 is folded. Insert from the opening between S1 and S5. After inserting the wire group of the wire harness 3, the sides S1 and S5 are overlapped, the locking protrusion 45 is inserted and locked into the locking hole 46, and the wire group of the wire harness 3 is inserted into the rectangular tube. doing.
The exterior material 5 has a configuration in which three sides S2, S3, and S4 of the rectangular tube are separated in the length direction by the cut line 48, and the sides S1 and S5 that are overlapped and locked are connected to be bent in the length direction, In addition, the separated side S3 is in a state in which the adjacent sides S3 are concavo-convexly fitted with arcuate cuts. That is, a short rectangular tube is sequentially connected in the length direction so that it can be bent, and the adjacent rectangular tubes are unevenly fitted to each other.
Using this caterpillar-type exterior material 5 having a square cylindrical shape, the extra-length absorbing case 6 is fitted with no backlash and can be moved in a stable posture.

前記外装材5でワイヤハーネス3を外装して、余長吸収ケース6に取り付ける工程について図5を参照して説明する。
図5(A)に示すように、余長吸収ケース6の本体60内に、出入口60iの蓋63を開いた状態で、図5(B)に示すように、ワイヤハーネス3に外装した外装材5を通す。四角筒状の外装材5の底面を本体60の底面に載せ、外装材5の前後面を本体60の外周壁60b、内周壁60cの内面に沿わせる。外装材5の先端5eを出入口6iに位置させ、該先端5eから引き出すワイヤハーネス3の電線群をテープ巻き片12上に載せる。この状態で外装材5の上面に前記穴11を位置させる。
A process of covering the wire harness 3 with the exterior material 5 and attaching it to the extra length absorption case 6 will be described with reference to FIG.
As shown in FIG. 5 (A), the exterior material covered on the wire harness 3 as shown in FIG. 5 (B) with the lid 63 of the entrance / exit 60i opened in the main body 60 of the surplus length absorption case 6. 5 is passed. The bottom surface of the rectangular tubular outer packaging material 5 is placed on the bottom surface of the main body 60, and the front and rear surfaces of the outer packaging material 5 are arranged along the inner surfaces of the outer peripheral wall 60 b and the inner peripheral wall 60 c of the main body 60. The front end 5e of the exterior material 5 is positioned at the entrance / exit 6i, and the electric wire group of the wire harness 3 drawn out from the front end 5e is placed on the tape winding piece 12. In this state, the hole 11 is positioned on the upper surface of the exterior member 5.

図5(C)に示すように、テープ巻き片12上のワイヤハーネス3の電線群に粘着テープ15を巻き付けて、ワイヤハーネス3をテープ巻き片12に固着する。
この状態で、蓋63を回転させて本体60の上面開口を閉鎖する動作で、図5(B)に矢印で示すように、係止突起10が外装材5の上面の穴11に差し込まれ、外装材5は余長吸収ケース6に固定される。
As shown in FIG. 5C, the adhesive tape 15 is wound around the wire group of the wire harness 3 on the tape winding piece 12, and the wire harness 3 is fixed to the tape winding piece 12.
In this state, by the operation of rotating the lid 63 to close the upper surface opening of the main body 60, the locking projection 10 is inserted into the hole 11 on the upper surface of the exterior member 5, as shown by the arrow in FIG. The exterior material 5 is fixed to the surplus length absorption case 6.

前記のようにワイヤハーネス3を外装材5で外装し、該外装材5を余長吸収ケース6に通したワイヤハーネス配索構造において、スライドシート1の前後移動に追従するワイヤハーネス3の動きを図6を参照して説明する。   In the wire harness routing structure in which the wire harness 3 is packaged with the exterior material 5 as described above, and the exterior material 5 is passed through the extra length absorption case 6, the movement of the wire harness 3 following the back and forth movement of the slide sheet 1 is controlled. This will be described with reference to FIG.

余長吸収ケース6の出入口6iでワイヤハーネス3は粘着テープ15で余長吸収ケース6のテープ巻き片12に固着され、外装材5は余長吸収ケース6の蓋63の係止突起10が穴11に差し込まれて固定される。該余長吸収ケース6はフロアに固定されるのに対して、外装材5およびワイヤハーネス3は余長吸収ケース6の出入口6iに固定されているだけで、他端の出入口にかけて摺動自在に余長吸収ケース6に通している。よって、外装材5は内部に挿通するワイヤハーネス3と共にスライドシート1の移動に追従して余長吸収ケース6内を移動する。即ち、余長吸収ケース6内のワイヤハーネス3の円弧状ターン部3tが余長吸収ケース6の湾曲部6bに対して近接および離反する方向に移動してスライドシート1の移動に追従する。   At the entrance / exit 6i of the surplus length absorption case 6, the wire harness 3 is fixed to the tape winding piece 12 of the surplus length absorption case 6 with an adhesive tape 15. 11 and fixed. The surplus length absorbing case 6 is fixed to the floor, whereas the exterior material 5 and the wire harness 3 are only fixed to the entrance / exit 6i of the surplus length absorbing case 6 and are slidable toward the entrance / exit of the other end. It passes through the extra length absorption case 6. Therefore, the exterior material 5 moves in the extra length absorption case 6 following the movement of the slide sheet 1 together with the wire harness 3 inserted therein. That is, the arcuate turn portion 3t of the wire harness 3 in the surplus length absorption case 6 moves in a direction approaching and separating from the curved portion 6b of the surplus length absorption case 6 to follow the movement of the slide sheet 1.

図6(A)はスライドシート1が後退した状態を示し、外装材5で外装したワイヤハーネス3も後退し、余長吸収ケース6内で湾曲部6bからワイヤハーネス3の円弧状ターン部3tが後端した状態となってスライドシート1の移動に追従する。
図6(B)はスライドシート1が前進した状態を示し、余長吸収ケース6内でワイヤハーネス3の円弧状ターン部3tが湾曲部6bに近接し、スライドシート1の移動に追従する。
FIG. 6A shows a state in which the slide sheet 1 is retracted, the wire harness 3 sheathed with the exterior material 5 is also retracted, and the arcuate turn portion 3t of the wire harness 3 is moved from the curved portion 6b within the extra length absorption case 6. The rear end state follows the movement of the slide sheet 1.
FIG. 6B shows a state in which the slide sheet 1 has moved forward, and the arcuate turn portion 3t of the wire harness 3 approaches the curved portion 6b in the surplus length absorption case 6 and follows the movement of the slide sheet 1.

前記のように、スライドシート1の前後移動に応じて、余長吸収ケース6内でワイヤハーネス3が移動する際に、ワイヤハーネス3に外装した外装材5は余長吸収ケース6の外周壁60bに沿って摺動し、その内部のワイヤハーネス3は出入口6iで外周壁寄りに突設したテープ巻き片12に巻き付けて外周壁寄りに拘束している。その結果、ワイヤハーネス3の曲げRを大きい状態で保持でき、ワイヤハーネスの屈曲性能を高めることができる。   As described above, when the wire harness 3 moves in the surplus length absorption case 6 according to the back-and-forth movement of the slide sheet 1, the exterior material 5 sheathed on the wire harness 3 is the outer peripheral wall 60 b of the surplus length absorption case 6. The wire harness 3 is wound around the tape winding piece 12 projecting toward the outer peripheral wall at the entrance 6i and restrained near the outer peripheral wall. As a result, the bending R of the wire harness 3 can be maintained in a large state, and the bending performance of the wire harness can be enhanced.

図7および図8に第2実施形態を示す。
第2実施形態では、余長吸収ケース6の出入口6iの部分で外装材5を固定する係止突起を本体60側から突設し、外装材5の上下に対向する穴11(11uと11b)に挿入固定するものである。
具体的には、図7(A)に示すように、余長吸収ケース6の本体60の底面60aの内周壁寄りの位置から1本の細長い丸棒状の係止突起70を突設する一方、蓋63の内面に係止突起70の先端が嵌合する凹部71を設けている。該棒状の係止突起70は本体の底面60aと蓋63との間の寸法と対応した長さとしている。
7 and 8 show a second embodiment.
In the second embodiment, a locking projection for fixing the exterior material 5 at the entrance / exit 6i of the extra length absorption case 6 is projected from the main body 60 side, and the holes 11 (11u and 11b) facing the top and bottom of the exterior material 5 are provided. It is to be inserted and fixed to.
Specifically, as shown in FIG. 7 (A), a single elongated round bar-like locking protrusion 70 is projected from a position near the inner peripheral wall of the bottom surface 60a of the main body 60 of the extra length absorption case 6, while A recess 71 is provided on the inner surface of the lid 63 to fit the tip of the locking projection 70. The rod-shaped locking projection 70 has a length corresponding to the dimension between the bottom surface 60 a of the main body and the lid 63.

また、係止突起70は外装材5の上下に対向する各1つの穴11、即ち、上面の穴11uと下面の穴11bとに貫通して通すため、断面は穴11u、11bの内径よりも小径としている。かつ、該係止突起70の突出側先端70aを円弧形状にして前記凹部71に嵌合させ、かつ、該突出側先端70aの外周に返り部70bを突設している。該返り部70bの直径は穴11の直径より若干大きくし、外装材5の下面の穴11bから上面の穴11uに通した係止突起70の返り部70bを穴11uの外周縁に係止できるようにしている。   Further, since the locking projection 70 passes through each of the holes 11 facing the top and bottom of the exterior material 5, that is, the hole 11u on the upper surface and the hole 11b on the lower surface, the cross section is larger than the inner diameters of the holes 11u and 11b. Small diameter. In addition, the protrusion-side tip 70a of the locking projection 70 is formed in an arc shape and fitted into the recess 71, and a return portion 70b is provided on the outer periphery of the protrusion-side tip 70a. The diameter of the return portion 70b is slightly larger than the diameter of the hole 11, and the return portion 70b of the locking projection 70 passing from the hole 11b on the lower surface of the exterior member 5 to the hole 11u on the upper surface can be locked to the outer peripheral edge of the hole 11u. I am doing so.

前記余長吸収ケース6の出入口6iでは、本体60の外周壁60bと内周壁60cの先端から互いに近接する方向に突出する外装材停止突起60e、60fを設けている。かつ、本体60の底面60aの先端からテープ巻き片12の平板部12aを外周壁60b寄りに突設している。かつ、前記第1実施形態と同様に、平板部12aを底面60aよりの段状に突出させると共に平板部12aの外周側縁から立ち上げ部12bを設け、テープ巻き片12を断面略L形状としている。他の構成は前記第1実施形態と同様であるため、同様の符号を付して説明を省略する。   At the entrance / exit 6i of the extra length absorption case 6, exterior material stop protrusions 60e and 60f are provided that protrude in the directions close to each other from the tips of the outer peripheral wall 60b and the inner peripheral wall 60c of the main body 60. And the flat plate part 12a of the tape winding piece 12 protrudes from the front-end | tip of the bottom face 60a of the main body 60 near the outer peripheral wall 60b. And like the said 1st Embodiment, the flat plate part 12a is protruded in the step shape from the bottom face 60a, and the raising part 12b is provided from the outer peripheral side edge of the flat plate part 12a, The tape winding piece 12 is made into cross-sectional substantially L shape. Yes. Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

前記第2実施形態においても、ワイヤハーネス3を外装材5で外装した状態で余長吸収ケース6内に挿通し、外装材5の長さ方向の一端を外装材停止突起60e、60fに突き当てる。本体60の底面60aから突出する係止突起70を外装材5の下面の穴11bに挿入し、外装材5の内部を貫通させ、上面の穴11uに挿入し、返り部70bを穴11uの周縁に係止する。   Also in the second embodiment, the wire harness 3 is inserted into the surplus length absorption case 6 with the exterior material 5 being sheathed, and one end in the length direction of the exterior material 5 is abutted against the exterior material stop protrusions 60e and 60f. . The locking projection 70 protruding from the bottom surface 60a of the main body 60 is inserted into the hole 11b on the lower surface of the exterior material 5, penetrates the interior of the exterior material 5, is inserted into the hole 11u on the upper surface, and the return portion 70b is the peripheral edge of the hole 11u. Lock to.

係止突起70は外装材5内に上下貫通させるが、内周側の側面に沿った位置に貫通させるため、外装材5の内部に挿通しているワイヤハーネス3の電線群に殆ど干渉する事なく貫通させることができる。
このように、係止突起70を貫通係止した外装材5の先端開口から引き出したワイヤハーネス3の電線群をテープ巻き片12に載せるように引き出す。
Although the locking projection 70 penetrates up and down in the exterior material 5, it penetrates to a position along the side surface on the inner peripheral side, so that it almost interferes with the wire group of the wire harness 3 inserted into the interior of the exterior material 5. It can penetrate without.
In this way, the wire group of the wire harness 3 pulled out from the front end opening of the exterior member 5 through which the locking protrusion 70 is locked is pulled out so as to be placed on the tape winding piece 12.

前記L形状としたテープ巻き片12の平板部12a上に載せたワイヤハーネス3の電線群を粘着テープ15で巻き付けて、ワイヤハーネス3をテープ巻き片12に固定する。このテープ巻き作業時にワイヤハーネス3の電線群を引っ張って外装材5が図8(D)に示すように変形しても、外装材5に係止突起70を貫通して係止しているため、係止突起70が外装材5から外れることは無く、蓋63を閉める前に仮置き固定できる。   The wire harness 3 placed on the flat plate portion 12 a of the L-shaped tape winding piece 12 is wound with the adhesive tape 15, and the wire harness 3 is fixed to the tape winding piece 12. Even when the exterior material 5 is deformed as shown in FIG. 8D by pulling the wire group of the wire harness 3 during the tape winding operation, the engagement projection 70 is penetrated and engaged with the exterior material 5. The locking projection 70 does not come off from the exterior material 5 and can be temporarily placed and fixed before the lid 63 is closed.

前記のように、係止突起70を外装材5の上下の穴11u、11bに通して貫通係止した後に、蓋63を本体60に向けて回転させて閉じ操作する。該操作により、蓋63の内面に設けた凹部71に係止突起70の突出側先端70aが嵌合し、係止突起70は位置決めされた状態で、蓋63と本体の底面60aの間に挟持固定される。   As described above, the locking projection 70 is passed through and locked through the upper and lower holes 11 u and 11 b of the exterior member 5, and then the lid 63 is rotated toward the main body 60 to be closed. By this operation, the protrusion-side tip 70a of the locking projection 70 is fitted into the recess 71 provided on the inner surface of the lid 63, and the locking projection 70 is positioned and clamped between the lid 63 and the bottom surface 60a of the main body. Fixed.

このように、外装材5を余長吸収ケース6に設けた係止突起70により貫通固定しているため、スライドシート1の前後移動時にワイヤハーネス3に引張負荷が作用して外装材5が変形しても、係止突起70は外装材5から外れる恐れはない。   Thus, since the exterior material 5 is fixed through by the locking projections 70 provided on the extra length absorption case 6, a tensile load acts on the wire harness 3 when the slide sheet 1 moves back and forth, and the exterior material 5 is deformed. Even so, there is no fear that the locking projection 70 is detached from the exterior material 5.
