Description

本発明は、ハーネス余長吸収用のプロテクタからワイヤハーネスをプロテクタ取付側に導出させて補機等に接続させる給電装置のハーネス配索構造に関するものである。   The present invention relates to a harness wiring structure of a power feeding device that leads a wire harness from a harness extra length absorption protector to a protector mounting side and connects it to an auxiliary machine or the like.

図6〜図7は、従来の給電装置の一形態を示すものである(特許文献1参照)。   6 to 7 show an embodiment of a conventional power feeding device (see Patent Document 1).

この給電装置51は、自動車のスライドドア41に縦置きに配設され、ワイヤハーネス43を屈曲自在に収容する合成樹脂製のプロテクタ50と、プロテクタ内でワイヤハーネス43を上向きに付勢する金属製の板ばね44とを備えたものである。   The power supply device 51 is arranged vertically on the slide door 41 of the automobile, and is made of a synthetic resin protector 50 that flexibly accommodates the wire harness 43, and a metal that urges the wire harness 43 upward in the protector. The leaf spring 44 is provided.

プロテクタ51はプロテクタベース(符号50で代用)とプロテクタカバー(図示せず)とで成り、プロテクタベース50とプロテクタカバーは、垂直な壁部52と湾曲状の周壁と垂直な壁部53に突設された環状の屈曲規制壁54とを有し、内側にワイヤハーネス43や板ばね44を組み付けた後、相互に係止固定される。屈曲規制壁54は板ばね44やワイヤハーネス43の最小屈曲径を規制する。屈曲規制壁54の内側は貫通した孔部56となっている。   The protector 51 includes a protector base (represented by reference numeral 50) and a protector cover (not shown). The protector base 50 and the protector cover protrude from a vertical wall portion 52, a curved peripheral wall, and a vertical wall portion 53. After the wire harness 43 and the leaf spring 44 are assembled on the inside, they are locked and fixed to each other. The bending restriction wall 54 restricts the minimum bending diameter of the leaf spring 44 and the wire harness 43. The inside of the bending restriction wall 54 is a through hole 56.

板ばね44はその基端部がワイヤハーネス43と共にプロテクタ50の屈曲規制壁54の後部側に固定され(固定部を符号59で示す)、板ばね44の先端に固定された合成樹脂製のキャップ49でワイヤハーネス43を摺接自在に支持している。プロテクタ50はそのブラケット66等がボルトでドアパネル41aに固定される。なお、明細書における前後上下左右の方向は車両の方向に一致させている。   The base end portion of the leaf spring 44 is fixed to the rear side of the bending restricting wall 54 of the protector 50 together with the wire harness 43 (the fixing portion is indicated by reference numeral 59), and the synthetic resin cap is fixed to the tip end of the leaf spring 44. 49, the wire harness 43 is slidably supported. The protector 50 has its bracket 66 and the like fixed to the door panel 41a with bolts. In the specification, the front-rear, up-down, left-right directions coincide with the vehicle direction.

ワイヤハーネス43は複数本の電線43aを合成樹脂製のコルゲートチューブ43bで覆って構成され、コルゲートチューブ43bの後端部がプロテクタ50にテープ巻き等で固定されている。コルゲートチューブ43bは周方向の凹溝と凸条とを蛇腹状に交互に有して良好な屈曲性を発揮する。   The wire harness 43 is configured by covering a plurality of electric wires 43a with a corrugated tube 43b made of synthetic resin, and a rear end portion of the corrugated tube 43b is fixed to the protector 50 by tape winding or the like. The corrugated tube 43b has a concave groove and a ridge in the circumferential direction alternately in a bellows shape, and exhibits good flexibility.

ワイヤハーネス43の一方の電線部分43aがプロテクタ50の後部開口57から導出されてスライドドア側のドアパネル41aに配置されたECU(電子制御ユニット)等の補機に接続され、ワイヤハーネス43の他方のコルゲートチューブ部分43bがプロテクタ50の長形の下部開口55から渡り空間46(図7)を経て車両ボディ47側の固定具58まで揺動自在に配索され、電線部分が固定具58から車両ボディ側(電源側)のワイヤハーネス(図示せず)に接続されている。渡り空間46においてワイヤハーネス43の各電線43aがコルゲートチューブ43bによって外部との干渉や水滴や塵等から安全に保護される。   One wire portion 43a of the wire harness 43 is led out from the rear opening 57 of the protector 50 and connected to an auxiliary device such as an ECU (Electronic Control Unit) disposed on the door panel 41a on the slide door side. The corrugated tube portion 43b is slidably routed from the elongated lower opening 55 of the protector 50 to the fixture 58 on the vehicle body 47 side through the crossing space 46 (FIG. 7), and the electric wire portion extends from the fixture 58 to the vehicle body. It is connected to a wire harness (not shown) on the side (power supply side). In the crossing space 46, each electric wire 43a of the wire harness 43 is safely protected from interference with the outside, water droplets, dust and the like by the corrugated tube 43b.

図6はスライドドア41の全閉状態、図7は同じく全開間近の半開状態をそれぞれ示している。スライドドア41の全閉状態でワイヤハーネス43は後方へ引っ張られ、スライドドア41の全開状態でワイヤハーネス43は前方へ引っ張られ、特にスライドドア41の半開状態でワイヤハーネス43は下向きに弛もうとするが、板ばね44で上向きに付勢されて弛み(余長)が吸収され、垂れ下がりやそれによる挟み込み等が防止される。   FIG. 6 shows the fully closed state of the slide door 41, and FIG. When the sliding door 41 is fully closed, the wire harness 43 is pulled rearward, and when the sliding door 41 is fully opened, the wire harness 43 is pulled forward. In particular, when the sliding door 41 is half open, the wire harness 43 tends to loosen downward. However, it is biased upward by the leaf spring 44 to absorb the slack (excess length), thereby preventing drooping and pinching caused by the slack.

上記各給電装置51ではワイヤハーネス43をプロテクタ50の後部側に固定して前部側から下部開口55を経て車両ボディ側に揺動自在に導出したが、ワイヤハーネス43をプロテクタ50の前部側に固定して後部側から下部開口55を経て車両ボディ側に揺動自在に導出させる形態は、例えば特許文献2に記載されている。この形態においても、プロテクタ50の中央の屈曲規制壁54の内側空間56を経てワイヤハーネス43をスライドドア側に導出させることは公知である。

In each of the power feeding devices 51, the wire harness 43 is fixed to the rear side of the protector 50 and led out from the front side through the lower opening 55 to the vehicle body side so as to be swingable, but the wire harness 43 is connected to the front side of the protector 50. For example, Patent Document 2 discloses a configuration in which the vehicle body is slidably led out from the rear side through the lower opening 55 to the vehicle body side. Also in this embodiment, it is known that the wire harness 43 is led out to the slide door side through the inner space 56 of the center bending restriction wall 54 of the protector 50.

図1〜図3は、本発明に係る給電装置のハーネス配索構造の一実施形態を示すものである。従来と同様ないし類似の構成部分には同じ符号を付して詳細な説明を省略する。   1 to 3 show an embodiment of a harness wiring structure for a power feeding device according to the present invention. Constituent parts that are the same as or similar to those in the prior art are denoted by the same reference numerals and detailed description thereof is omitted.

図1の如く、この給電装置1のハーネス配索構造は、合成樹脂製のプロテクタ50´のプロテクタベース(符号50´で代用)に略環状の屈曲規制壁54を設け、屈曲規制壁54の内側にハーネス導出壁(導出部)57´を設け、ハーネス導出壁57´に沿ってワイヤハーネス43の電線部分(他方の部分)43aを固定させずに略波形状に屈曲させることで余長部43a´を形成したことを特徴とするものである。   As shown in FIG. 1, the harness wiring structure of the power feeding device 1 is provided with a substantially annular bending restriction wall 54 on a protector base (a substitute for reference numeral 50 ′) of a protector 50 ′ made of synthetic resin, and the inside of the bending restriction wall 54. Is provided with a harness lead-out wall (lead-out portion) 57 ', and the wire portion (the other portion) 43a of the wire harness 43 is not fixed along the harness lead-out wall 57', and is bent into a substantially wave shape, thereby surplus length portion 43a. ′ Is formed.

図2の如く、余長部43a´を伸長させることで、電線部分43aを従来(鎖線で示す)よりも延長して、ドアパネル(プロテクタ取付側)41aの座部65との間に従来よりも広い(手を入れる)作業スペース69を確保し、ドアパネル側のECU(他方の接続部)64に電線部分43aをコネクタ接続した後、図3の如く、座部65にプロテクタ50´を組み付ける際に電線部分43aをプロテクタ内に引き込ませて、ハーネス導出壁57´とECU64との間の電線部分43aを短縮することで、鎖線のような電線部分43aの挟み込みを防止することができる。   As shown in FIG. 2, by extending the surplus length portion 43a ', the electric wire portion 43a is extended from the conventional one (indicated by a chain line) and between the seat portion 65 of the door panel (protector mounting side) 41a than the conventional one. When a large work space 69 is secured and the electric wire portion 43a is connected to the door panel side ECU (the other connecting portion) 64 by a connector, the protector 50 'is assembled to the seat portion 65 as shown in FIG. By pulling the electric wire portion 43a into the protector and shortening the electric wire portion 43a between the harness lead-out wall 57 'and the ECU 64, it is possible to prevent the electric wire portion 43a such as a chain line from being caught.

図1の如く、プロテクタ50´は従来同様にプロテクタベース(50´で代用)とプロテクタカバー(図示せず)とで構成され、プロテクタベース50´とプロテクタカバーとは垂直な壁部52と湾曲状の周壁53とで構成され、プロテクタカバーを外した状態でプロテクタベース50´に、キャップ(ハーネス支持具)49を有する板ばね44とワイヤハーネス43とを組み付け、プロテクタカバーを閉止することで、給電装置1が構成される。   As shown in FIG. 1, the protector 50 'is composed of a protector base (instead of 50') and a protector cover (not shown) as in the prior art, and the protector base 50 'and the protector cover have a vertical wall 52 and a curved shape. The plate spring 44 having the cap (harness support) 49 and the wire harness 43 are assembled to the protector base 50 ′ with the protector cover removed, and the protector cover is closed to supply power. A device 1 is configured.

電線余長部43a´は予め波形ないし螺旋状に弾性復帰する癖をつけておくことが好ましい。こうすれば、図3の鎖線の電線部分43aの挟み込みを防止すべく、電線部分43aを作業者が意識的にプロテクタ50´内に押し込む必要がなく、ECU64にコネクタ接続された電線部分43aの余長部43a´が自動的にプロテクタ内に引き込まれる。   It is preferable that the wire surplus portion 43a ′ is previously provided with a hook that elastically returns to a waveform or a spiral. In this way, it is not necessary for the operator to consciously push the electric wire portion 43a into the protector 50 'in order to prevent the electric wire portion 43a of the chain line in FIG. The long part 43a 'is automatically drawn into the protector.

電線部分43aに上記のような復帰癖をつけない場合は、図3のプロテクタ50´の取付時に、プロテクタ50´の屈曲規制壁54の内側空間56に外側から手を入れて電線部分43aをプロテクタ50´のハーネス導出壁57´内に押し込むようにする。あるいは、プロテクタカバー(図示せず)を開けた状態で電線部分43aをプロテクタベース50´内に引き込みつつプロテクタベース50´を座部65に固定し、プロテクタカバーを閉めることも可能である。   When the above-described return rod is not attached to the electric wire portion 43a, when the protector 50 'shown in FIG. 3 is attached, the electric wire portion 43a is inserted into the inner space 56 of the bending restriction wall 54 of the protector 50' from the outside. It is pushed into the 50 'harness lead-out wall 57'. Alternatively, with the protector cover (not shown) opened, the protector base 50 ′ can be fixed to the seat 65 while the wire portion 43 a is pulled into the protector base 50 ′, and the protector cover can be closed.

電線部分43aはプロテクタ内のワイヤハーネス43のコルゲートチューブ(一方の部分)43b内に挿通され、コルゲートチューブ43bは屈曲規制壁54の後部側に板ばね44の基端部44aと共に固定されている。コルゲートチューブ部分43bはプロテクタ50´の長形の下部開口55から車両ボディ側のハーネス固定具58(図6参照)に配索され、コルゲートチューブ43bから導出された電線部分が図示しない車両ボディ側のワイヤハーネス(一方の接続部)にコネクタ接続される。   The electric wire portion 43 a is inserted into a corrugated tube (one portion) 43 b of the wire harness 43 in the protector, and the corrugated tube 43 b is fixed to the rear side of the bending regulating wall 54 together with the base end portion 44 a of the leaf spring 44. The corrugated tube portion 43b is routed from the elongated lower opening 55 of the protector 50 'to the harness fixture 58 (see FIG. 6) on the vehicle body side, and the electric wire portion led out from the corrugated tube 43b is not shown on the vehicle body side. A connector is connected to the wire harness (one connecting portion).

プロテクタ50´のハーネス導出部57´は例えば板状あるいは矩形筒状に形成され、ハーネス導出部57´の少なくとも基端部分62aは屈曲規制壁54を切欠した開口としてプロテクタベース50´内のハーネス収容空間に連通している。ハーネス導出部57´を矩形筒状に形成すれば、矩形筒状部内の空間に電線余長部43a´を波状ないし螺旋状に屈曲させた状態に安定に収容することができる。ハーネス導出部57´として、例えばプロテクタベース50´の断面Lないしコの字状の板部(57´で代用)に対向してプロテクタカバー(図示せず)に同様の板部を設け、プロテクタカバーの閉止時に両板部(57´)を接合してハーネス導出部57´を構成させることも可能である。これらハーネス導出部57´はプロテクタ50´に一体樹脂成形される。   The harness lead-out portion 57 ′ of the protector 50 ′ is formed in, for example, a plate shape or a rectangular cylinder shape, and at least the base end portion 62 a of the harness lead-out portion 57 ′ is an opening in which the bending restricting wall 54 is cut out. It communicates with space. If harness lead-out part 57 'is formed in a rectangular cylinder shape, electric wire surplus part 43a' can be stably accommodated in the space in the rectangular cylinder part in the state bent in the shape of a wave or a spiral. As the harness lead-out portion 57 ′, for example, a similar plate portion is provided on a protector cover (not shown) so as to face the cross-section L of the protector base 50 ′ or a U-shaped plate portion (in place of 57 ′). It is also possible to form the harness lead-out portion 57 'by joining both the plate portions (57') when closed. These harness lead-out portions 57 'are integrally molded with the protector 50'.

図4,図5は、上記ハーネス導出部57´に逆ラッパ状に縮径したハーネス誘い込み部70を一体に設けた給電装置1´を示すものである。他の構成は図1と同様であるので、同じ部分に同じ符号を付して詳細な説明を省略する。   4 and 5 show a power feeding device 1 ′ in which a harness guiding portion 70 having a diameter reduced to a reverse trumpet shape is integrally provided on the harness lead-out portion 57 ′. Since other configurations are the same as those in FIG. 1, the same parts are denoted by the same reference numerals and detailed description thereof is omitted.

ハーネス誘い込み部70は短い筒状ないし断面湾曲したヘラ状に形成され(ハーネス導出部57´が筒状である場合、ハーネス誘い込み部70は筒状に形成され、ハーネス導出部57´が板状である場合、ハーネス誘い込み部70は湾曲したヘラ(板)状に形成され、)ECU64にコネクタ接続された電線部分43aをスムーズにハーネス導出部57´内に誘導させて、矢印Aの如く電線余長部43a´の引き込みないし押し込みをスムーズ且つ確実に行わせる。   The harness lead-in portion 70 is formed in a short cylindrical shape or a spatula having a curved cross section (when the harness lead-out portion 57 ′ is cylindrical, the harness lead-in portion 70 is formed in a cylindrical shape, and the harness lead-out portion 57 ′ is plate-shaped.
