Description

本発明はワイヤハーネスの余長吸収装置に関し、詳しくは、自動車において、車体と、該車体に対して回転あるいは移動するドランクリッド、ドア、スライドシート等の間に配索されるワイヤハーネスには回転や移動に追従できる余長を設けており、該余長を吸収できる装置に関するものである。   The present invention relates to a surplus length absorbing device for a wire harness, and more particularly, to a wire harness routed between a vehicle body and a drunk lid, a door, a slide seat, etc. that rotate or move relative to the vehicle body in an automobile. Further, the present invention relates to a device that is provided with a surplus length that can follow the movement and can absorb the surplus length.

従来、自動車の車体とトランクリッド等の間に配索されるワイヤハーネスはトランクリッドの開閉動作に追従して伸縮させる必要があるため、開放時に必要な余長を設け、閉鎖時には余長を吸収できる余長吸収装置を設けている。
この種の余長吸収装置として、本出願人は従来多数の提案をしており、例えば、特開２００４−１１４８２２号公報では、図５に示すスプールプロテクタを提供している。 Conventionally, the wire harness routed between the car body and the trunk lid, etc., must be expanded and contracted following the opening / closing operation of the trunk lid. An extra length absorbing device that can be used is provided.
As this type of extra length absorber, the present applicant has conventionally proposed a number of proposals. For example, Japanese Patent Application Laid-Open No. 2004-114822 provides a spool protector shown in FIG.

前記スプールプロテクタでは、ケース１００内に電線巻付用円筒１０１をガイド溝１０３に沿って移動自在に取り付けると共に、該電線巻付用円筒１０１とケース周壁との間に環状ゴムバネ１０２を取り付け、ケース１００内に引き込んだワイヤハーネス１１０を電線巻付用円筒１０１の外周面に巻き付けている。
ワイヤハーネス１１０の余長をケース１００内に収容時は環状ゴムバネ１０２により図５（Ａ）に電線巻付用円筒１０１を位置させ、余長がケース１００より引き出される際には、環状ゴムバネ１０２を引き伸ばして、電線巻付用円筒１０１を図５（Ｂ）まで移動させている。 In the spool protector, an electric wire winding cylinder 101 is movably attached to the case 100 along the guide groove 103, and an annular rubber spring 102 is attached between the electric wire winding cylinder 101 and the case peripheral wall. The wire harness 110 drawn in is wound around the outer peripheral surface of the wire winding cylinder 101.
When the extra length of the wire harness 110 is accommodated in the case 100, the wire winding cylinder 101 is positioned in FIG. 5A by the annular rubber spring 102, and when the extra length is pulled out from the case 100, the annular rubber spring 102 is The wire winding cylinder 101 is moved to the position shown in FIG.

特開２００４−１１４８２２号公報JP 2004-114822 A

前記図５に示すスプールプロテクタでは、ワイヤハーネスの移動に追従させて、環状ゴムバネ１０２からなるゴム輪でワイヤハーネスを外周に巻き付けた電線巻付用円筒１０１を移動させているため、経年使用すると環状ゴムバネ１０２が劣化する恐れがあり、其の点で改善の余地がある。かつ、電線巻付用円筒１０１を所要の軌跡で案内するガイド溝１０３をケース１００に設ける必要があると共に、電線巻付用円筒１０１にガイド溝に嵌合する突起部を設ける必要がある。このように、構成が複雑となっている。   In the spool protector shown in FIG. 5, the wire winding cylinder 101 having the wire harness wound around the outer periphery is moved by a rubber ring made of the annular rubber spring 102 so as to follow the movement of the wire harness. The rubber spring 102 may be deteriorated, and there is room for improvement in that respect. In addition, it is necessary to provide the case 100 with a guide groove 103 that guides the wire winding cylinder 101 along a required locus, and it is also necessary to provide a protrusion that fits into the guide groove in the wire winding cylinder 101. Thus, the configuration is complicated.

本発明は前記問題に鑑みてなされたもので、簡単な構成のワイヤハーネスの余長吸収装置を提供することを課題としている。   This invention is made | formed in view of the said problem, and makes it the subject to provide the surplus length absorber of a wire harness of a simple structure.

前記課題を解決するため、本発明は、
車体と、該車体に対して回転または移動する作動部材との間に架け渡すワイヤハーネスを挿通するケースを備え、該ケースの入口と出口の間の膨出させた余長吸収空間を設け、該余長吸収部内に一端を前記ケースに支軸を介して回転自在に取り付けたレバーを配置し、該レバーの他端に滑車を回転自在に軸着すると共に該レバーと入口側のケースの周壁との間に圧縮バネを張架し、ワイヤハーネスの余長部分の移動に応じて前記滑車が前記レバーを前記圧縮バネに抗して回転させて追従させる構成としていることを特徴とするワイヤハーネスの余長吸収装置を提供している。 In order to solve the above problems, the present invention provides:
A case in which a wire harness that spans between the vehicle body and an operating member that rotates or moves with respect to the vehicle body is inserted, and a bulging surplus length absorption space is provided between the inlet and the outlet of the case, A lever having one end rotatably attached to the case via a support shaft is disposed in the surplus length absorbing portion, and a pulley is rotatably attached to the other end of the lever. The lever and the peripheral wall of the case on the inlet side The wire harness is characterized in that a compression spring is stretched between the pulleys and the pulley rotates the lever against the compression spring to follow the movement of the extra length portion of the wire harness. An extra length absorber is provided.

前記レバーの支軸は、前記入口と出口を結ぶ直線上または該直線に近接した位置に配置し、余長吸収空間からワイヤハーネスが引き出される作動時は、前記入口と出口を結ぶ直線に近接する方向に前記レバーを介して滑車が回転する一方、前記余長吸収空間にワイヤハーネスが引き込まれる作動時は、前記直線から離れる方向に滑車が回転し、前記レバーが前記直線と直交方向となって前記ワイヤハーネスの余長部を吸収している。   The support shaft of the lever is arranged on a straight line connecting the inlet and the outlet or at a position close to the straight line, and close to the straight line connecting the inlet and the outlet when the wire harness is pulled out from the extra length absorption space. While the pulley rotates in the direction through the lever, the pulley rotates in a direction away from the straight line when the wire harness is pulled into the extra length absorption space, and the lever is in a direction orthogonal to the straight line. The extra length of the wire harness is absorbed.

即ち、ワイヤハーネスを巻き付けた滑車は回転自在なレバーの先端に取り付けているため、レバーに連結している前記圧縮バネの付勢力に抗してワイヤハーネスの引き出しに連動して回転する。一方、ワイヤハーネスが引き込まれる状態で弛んでくると滑車はレバーを介して圧縮バネの引っ張り力で元の位置に回転して戻り、該滑車に巻き付けたワイヤハーネスを余長吸収位置に強制的に戻すことができる。   That is, since the pulley around which the wire harness is wound is attached to the tip of a rotatable lever, the pulley rotates in conjunction with the pull-out of the wire harness against the urging force of the compression spring connected to the lever. On the other hand, if the wire harness is loosened while being pulled, the pulley rotates back to the original position by the pulling force of the compression spring through the lever, and the wire harness wound around the pulley is forced to the extra length absorption position. Can be returned.

前記出口より引き出したワイヤハーネスを取り付ける前記作動部材はトランクリッド、サイドドア、バックドア等の回転体、あるいはスライドシート等の移動体からなり、これら回転体または移動体と車体との間に前記ワイヤハーネスを配索し、前記作動部材側あるいは車体側に前記余長吸収装置のケースを取り付けている。   The actuating member to which the wire harness drawn out from the outlet is attached includes a rotating body such as a trunk lid, a side door, and a back door, or a moving body such as a slide seat, and the wire is interposed between the rotating body or the moving body and the vehicle body. A harness is routed, and a case of the surplus length absorber is attached to the operating member side or the vehicle body side.

ワイヤハーネスは、被覆丸電線を集束したワイヤハーネスでも良いし、導体を平行配線して絶縁シートでラミネートしたフラットハーネスでもよい。   The wire harness may be a wire harness in which covered round electric wires are converged, or a flat harness in which conductors are wired in parallel and laminated with an insulating sheet.

前述したように、本発明の余長吸収装置では、ケース内部に回転自在に支持したレバーの先端に滑車を設け、該滑車にワイヤハーネスを巻き付けると共に、前記レバーとケースの内面に圧縮バネを張架した構成としているため、ワイヤハーネスの移動に追従して出口側へ近接した位置へとレバーおよび滑車を回転して余長部を引き出すことができる一方、ワイヤハーネスの引き戻し時にも圧縮バネでレバーおよび滑車を元の余長吸収位置に強制的に戻すため、滑車に巻き付けたワイヤハーネスの余長部を余長吸収空間に引き込むことができる。   As described above, in the surplus length absorbing device of the present invention, a pulley is provided at the tip of a lever rotatably supported inside the case, a wire harness is wound around the pulley, and a compression spring is stretched between the lever and the inner surface of the case. Since it has a built-up configuration, it can follow the movement of the wire harness and rotate the lever and pulley to a position close to the exit side to pull out the extra length, while the wire harness is pulled back with a compression spring Since the pulley is forcibly returned to the original excess length absorption position, the excess length portion of the wire harness wound around the pulley can be drawn into the excess length absorption space.

以下、本発明の実施形態を図面を参照して説明する。
図１乃至図３に第一実施形態の余長吸収装置１を示す。
実施形態では、車体とトランクリッドとの間に配索する被覆丸電線の集合体からなるワイヤハーネス２に設けた余長部２ａを吸収するもので、ワイヤハーネス２の車体側の配索経路に配置し、車体に固定している。該ワイヤハーネス２はトランクリッドの開き時に余長部２ａが余長吸収装置１から引き出され、トランクリッドの閉鎖時に引き出された余長部２ａが余長吸収装置１内に収容できるものとしている。即ち、車体に対して回転する作動部材がトランクリッドからなるものを対象としている。
なお、作動部材はトランクリッドに限定されず、前記のように、サイドドア、バックドアからなる回転体、あるいは、スライドシートからなる移動体でもよい。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The surplus length absorber 1 of 1st embodiment is shown in FIG. 1 thru | or FIG.
In the embodiment, the extra length portion 2a provided in the wire harness 2 formed of the aggregate of the covered round electric wires routed between the vehicle body and the trunk lid is absorbed, Arranged and fixed to the car body. The wire harness 2 is configured such that when the trunk lid is opened, the surplus length portion 2a is pulled out from the surplus length absorbing device 1, and the surplus length portion 2a pulled out when the trunk lid is closed can be accommodated in the surplus length absorbing device 1. That is, it is intended that the operating member that rotates relative to the vehicle body is made of a trunk lid.
The actuating member is not limited to the trunk lid, and may be a rotating body including a side door and a back door or a moving body including a slide seat as described above.

余長吸収装置１は上面開口の有底ケース１０と、該ケース１０の上面開口を閉鎖する蓋１１を備えている。
前記ケース１０の対向する左右周壁１０ａの上端には、ワイヤハーネス挿通溝を設け、蓋１１との間に入口１２と出口１３とを対向して設けている。入口１２から車体に配索しているワイヤハーネス２を挿入し、出口１３より引き出してトランクリッド側へと配索している。 The surplus length absorbing device 1 includes a bottomed case 10 having an upper surface opening and a lid 11 for closing the upper surface opening of the case 10.
A wire harness insertion groove is provided at the upper ends of the opposing left and right peripheral walls 10 a of the case 10, and an inlet 12 and an outlet 13 are provided facing the lid 11. The wire harness 2 routed from the entrance 12 to the vehicle body is inserted, pulled out from the exit 13 and routed to the trunk lid side.

前記ケース１０は入口１２と出口１３を上端に設けた左右周壁１０ａの下部を互いに近接する方向に湾曲され底壁１０ｂを円弧形状としている。左右側壁１０ａと直交方向の前後壁１０ｃの間はワイヤハーネス２の太さよりも若干大きい寸法とし、ケース１０の全体は大略半円形状の縦置き又は横置きのケースとしている。前記左右周壁１０ａ、底壁１０ｂおよび前後周壁１０ｃで囲まれた空間を余長吸収空間１５としている。   The case 10 is curved in a direction in which the lower portions of the left and right peripheral walls 10a having the inlet 12 and the outlet 13 at the upper ends thereof are close to each other, and the bottom wall 10b has an arc shape. The space between the left and right side walls 10a and the front and rear walls 10c in the orthogonal direction is slightly larger than the thickness of the wire harness 2, and the entire case 10 is a generally semicircular vertical or horizontal case. A space surrounded by the left and right peripheral walls 10a, the bottom wall 10b, and the front and rear peripheral walls 10c is defined as a surplus length absorption space 15.

前記ケース１０内には、前記入口１２と出口１３とを結ぶ仮想線上に、後壁１０ｃ−１に支軸１６を突設し、該支軸１６にレバー１７の上端を回転自在に軸着している。該レバー１７の下端に滑車１８を回転自在に取り付けている。滑車１８は左右周壁１０ａ及び底壁１０ｂとの間にワイヤハーネス２を介在できる空間をかけて位置させている。
前記滑車１８は図２に示すように、外周面の断面を円弧状凹部１８ａとし、ワイヤハーネス２の半周部を円弧状凹部１８ａ内に摺動自在に嵌合できるようにしている。
かつ、レバー１７と入口１２側の図中右側周壁１０ａ−１との間に圧縮バネ１９を張架し、レバー１７および滑車１８を余長吸収位置Ｓ１に戻るように付勢している。 In the case 10, a support shaft 16 protrudes from the rear wall 10 c-1 on an imaginary line connecting the inlet 12 and the outlet 13, and the upper end of the lever 17 is rotatably attached to the support shaft 16. ing. A pulley 18 is rotatably attached to the lower end of the lever 17. The pulley 18 is positioned over a space in which the wire harness 2 can be interposed between the left and right peripheral walls 10a and the bottom wall 10b.
As shown in FIG. 2, the pulley 18 has an arc-shaped recess 18a as a cross section of the outer peripheral surface, and a semicircular portion of the wire harness 2 can be slidably fitted into the arc-shaped recess 18a.
In addition, a compression spring 19 is stretched between the lever 17 and the right peripheral wall 10a-1 in the drawing on the inlet 12 side, and the lever 17 and the pulley 18 are urged so as to return to the excess length absorbing position S1.

前記余長吸収空間１５内で、レバー１７および滑車１８は、圧縮バネ１９の引っ張り力で、図１に示すように、滑車１８が底壁１０ｂに向けて垂下し、入口１２と出口１３を結ぶ直線Ｌと離れた位置Ｓ１（以下、余長吸収位置と称す）に回転する方向になる。
よって、ワイヤハーネス２に引き出し方向の負荷が作用しない状態では、滑車１８は図１の余長収容空間１５内で余長吸収位置Ｓ１に位置し、外周に巻き付けたワイヤハーネス２の余長部２ａを底壁１０ｂに近接させて位置させ、余長収容空間１５内に左右周壁１０ａおよび底壁１０ｂに沿って大きく湾曲して余長を吸収している。 In the surplus length absorption space 15, the lever 17 and the pulley 18 are suspended toward the bottom wall 10 b by the pulling force of the compression spring 19, and connect the inlet 12 and the outlet 13 as shown in FIG. 1. The rotation direction is a position S1 away from the straight line L (hereinafter referred to as a surplus length absorption position).
Therefore, in a state in which no load in the pulling direction acts on the wire harness 2, the pulley 18 is located in the extra length absorption position S1 in the extra length accommodation space 15 in FIG. 1 and the extra length portion 2a of the wire harness 2 wound around the outer periphery. Is positioned close to the bottom wall 10b, and the extra length is absorbed in the extra length accommodation space 15 by being largely curved along the left and right peripheral walls 10a and the bottom wall 10b.

前記図３（Ａ）に示す位置はトランクリッドが閉鎖されている時のワイヤハーネス２の位置である。トランクリッドの開き作動が行われ、出口１３より引き出されているワイヤハーネス２に引き出し方向に引っ張られると、ワイヤハーネス２が巻き付けられた滑車１８も引っ張られる。それに伴い、滑車１８を取り付けたレバー１７は圧縮バネ１９の付勢力に抗して支軸１６を支点として回転し、レバー１７の先端の滑車１８がワイヤハーネス２の引き出しに追従して出口１３に向けて回転する。最終的に、図３（Ｂ）に示すように、出口１３と支軸１６とを結ぶ直線と略平行状になる位置Ｓ２まで回転する。   The position shown in FIG. 3A is the position of the wire harness 2 when the trunk lid is closed. When the opening operation of the trunk lid is performed and the wire harness 2 pulled out from the outlet 13 is pulled in the pulling direction, the pulley 18 around which the wire harness 2 is wound is also pulled. Accordingly, the lever 17 to which the pulley 18 is attached rotates with the support shaft 16 as a fulcrum against the urging force of the compression spring 19, and the pulley 18 at the tip of the lever 17 follows the drawer of the wire harness 2 to the outlet 13. Rotate towards. Finally, as shown in FIG. 3 (B), it rotates to a position S2 that is substantially parallel to a straight line connecting the outlet 13 and the support shaft 16.

トランクリッドが開き位置から閉じ動作されると、引き出されていたワイヤハーネス２が緩み、圧縮バネ１９の引っ張り力によりレバー１７および滑車１８は元の余長吸収位置の底面１０ｂ側に向けて回転し、該滑車１８に嵌合したワイヤハーネス２も追従して底面１０ｂ側に引き込まれる。滑車１８が余長吸収位置Ｓ１に位置することで、引き出されたワイヤハーネス２の余長部２ａをケース１０内に確実に収容することができる。   When the trunk lid is closed from the open position, the drawn wire harness 2 is loosened, and the lever 17 and the pulley 18 are rotated toward the bottom surface 10b side of the original excess length absorbing position by the pulling force of the compression spring 19. The wire harness 2 fitted to the pulley 18 also follows and is pulled to the bottom surface 10b side. By positioning the pulley 18 at the surplus length absorption position S1, the surplus length portion 2a of the drawn wire harness 2 can be reliably accommodated in the case 10.

このように、第一実施形態では、レバー１７を介して自在に回転する滑車１８にワイヤハーネス２を嵌合させた簡単な構成で、ワイヤハーネスの移動に追従させて余長を吸収することができる。   Thus, in the first embodiment, the excess length can be absorbed by following the movement of the wire harness with a simple configuration in which the wire harness 2 is fitted to the pulley 18 that freely rotates via the lever 17. it can.

図５（Ａ）（Ｂ）に第二実施形態を示す。
第二実施形態では、ワイヤハーネスはフラットハーネス２０としており、滑車１８の外周面にフラットハーネス２０を挟むように幅方向の両側にＬ形状のガイド枠２１を設けている。
また、ケース３０は水平配置し、底壁３０ａから支軸１６を突設し、レバー１７および滑車１８は水平方向に回転できるようにしている。レバー１７と出口１３側の周壁３０ｂとの間に圧縮バネ１９を取り付けている。
他の構成は第一実施形態と同様であるため、同一符号を付して説明を省略する。 5A and 5B show a second embodiment.
In the second embodiment, the wire harness is a flat harness 20, and L-shaped guide frames 21 are provided on both sides in the width direction so as to sandwich the flat harness 20 on the outer peripheral surface of the pulley 18.
Further, the case 30 is horizontally arranged, and the support shaft 16 is projected from the bottom wall 30a so that the lever 17 and the pulley 18 can rotate in the horizontal direction. A compression spring 19 is attached between the lever 17 and the peripheral wall 30b on the outlet 13 side.
Since other configurations are the same as those of the first embodiment, the same reference numerals are given and description thereof is omitted.

前記のように、レバー１７および滑車１８を水平方向に回転させてフラットハーネス２０の余長部を吸収する場合には、レバー１７と圧縮バネ１９で余長吸収位置Ｓ１に付勢していることで、フラットハーネス２の移動に追従して余長部を吸収することができる。   As described above, when the lever 17 and the pulley 18 are rotated in the horizontal direction to absorb the surplus length portion of the flat harness 20, the lever 17 and the compression spring 19 are biased to the surplus length absorbing position S1. Thus, the extra length can be absorbed following the movement of the flat harness 2.
