Description

【０００１】
【発明の属する技術分野】
本発明は、バンド等の結束手段で電線を確実に保持させることのできる電線クランプに関するものである。
【０００２】
【従来の技術】
図６は従来の電線クランプの一形態を示すものである。
この電線クランプ５１は、複数本の電線５２であるワイヤハーネスをバンド５３やテープ巻きで固定させる合成樹脂製の基板部５４と、基板部５４の一端側に一体に形成され、車両のパネル等の孔（図示せず）に挿入係止される係止用クリップ５５とで構成されている。
【０００３】
基板部５４の他端には抜け止め用の突条５６が一体に形成され、ワイヤハーネス５２に基板部５４を位置ずれなく固定可能である。基板部５４には複数本の電線５２のみならず、一本の電線を固定することも可能である。バンド５３は合成樹脂を材料として帯状に形成され、バンド本体５７と、バンド本体５７の基端に一体に設けられた係止用の枠部５８とで構成されている。
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の電線クランプ５１にあっては、電線５２をテープ巻きで固定する場合に多くの工数を必要とし、且つテープ巻きの自動化が困難であるために、作業の効率化を図るべく合成樹脂製のバンド５３を用いて電線５２を固定する訳であるが、その場合には、図７で示す如く太径のワイヤハーネス５２や電線に対しては基板部５４に強く固定することができるが、図８に示す如く細径の電線５９に対しては、バンド５３が扁平に締まりにくいために、バンド５３と電線５２との間に隙間６０を生じやすく、電線５９の保持力が弱く、保持が十分に行われずに、電線５９がガタついたりして摩耗や破損を起こすという懸念があった。また、基板部５４が平坦で電線５９の仮置きがしにくく、電線５９の固定作業性が悪いという問題もあった。
【０００５】
本発明は、上記した点に鑑み、太い電線は勿論のこと、細い電線でも強い力でガタつきなくしっかりと締め付け固定することができ、しかも電線の固定作業性を高めることのできる電線クランプを提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、本発明の請求項１に係る電線クランプは、基板部に結束部材を巻回させて電線を該結束部材で固定させる電線クランプにおいて、前記基板部の幅方向中央に、前記電線の長手方向に沿う断面山型状の凸状部が形成され、該凸状部の左右両側に電線が分離して配置され、該凸状部の電線長手方向の前後両端側で該基板部の左右両側に電線ガイド部が各一対突設され、各電線ガイド部が内側に湾曲面を有し、前後一対の該電線ガイド部の間に前記結束部材が配置され、左右一対の該電線ガイド部の該湾曲面の内幅よりも該基板部の外幅が広く設定されたことを特徴とする。
上記構成により、基板部の幅方向中央に凸状部があるから、電線が基板部の中央に位置することがなく、例えば二本の電線が凸状部の両側に離れて位置するから、バンド等の結束手段（結束部材）で電線を基板部に結束する際に、結束手段が扁平にならず略長円形ないし略三角形になって基板部の中央に隙間を生じても、結束手段の両側の傾斜状の部分が電線に接して電線を基板部に確実に押圧保持する。また、特に細径の電線を用いた場合に、電線が凸状部で押し上げられて、バンド等の結束手段と電線との間の隙間が防止され、電線が結束手段で確実に締め付け保持される。また、電線が基板部の表面と凸状部の傾斜面との二面で同時に接して位置決めされるから、電線の位置ずれが防止され、電線の保持性が向上する。
また、凸状部と電線ガイド部との間に電線が挟まれるようにして位置し、電線の外側への移動が電線ガイド部で阻止され、電線の内側への移動が凸状部で阻止されて、電線の保持性及び位置決め性が向上する。また、電線ガイド部の内側に電線を容易に仮置き（セット）することができ、結束手段での電線の保持作業が容易化する。
また、結束手段で電線を基板部に固定した際に、電線ガイド部の内側の湾曲面に電線が強く押接し、電線に内向きの反力が作用して、電線の保持力が高まる。
また、両側の電線ガイド部の間に複数本の電線が確実に仮置きされ、次いで両側の電線ガイド部の間で複数本の電線が結束手段で確実に締め付け保持される。各電線には締め付け中心に向かう反力が作用し、電線の保持性が向上する。
【０００７】
請求項２に係る電線クランプは、請求項１に係る電線クランプにおいて、前記基板部の幅方向両端側に、前記凸状部と同方向に傾斜した傾斜面が形成され、前記結束部材が該傾斜面と前記電線とに同時に接触することを特徴とする。
【００１０】
請求項３に係る電線クランプは、請求項１又は２に係る電線クランプにおいて、前記電線ガイド部が前記凸状部よりも高く突出されたことを特徴とする。
上記構成により、電線ガイド部による電線の仮置き性が向上すると共に、電線の本数や径の増加に対応できて、電線の保持性が向上する。
【００１２】
請求項４に係る電線クランプは、請求項１〜３の何れか１項に係る電線クランプにおいて、前記凸状部の傾斜面に前記電線ガイド部の内側の湾曲面が交差して位置し、該凸状部の傾斜面と該電線ガイド部の内側の湾曲面とのなす角度が、該凸状部の傾斜面と前記基板部とのなす角度よりも小さく、該凸状部の傾斜面と該電線ガイド部の内側の湾曲面とに前記電線が同時に接触することを特徴とする。
上記構成により、特に細径の電線が電線ガイド部と凸状部との交差部上に位置して、凸状部の傾斜面と電線ガイド部の湾曲面とに同時に二点接触するから、電線の位置決め性及び保持性が向上する。
【００１３】
【発明の実施の形態】
以下に本発明の実施の形態を図面に基づいて詳細に説明する。
図１〜図２は、本発明に係る電線クランプにおいて少数本の細径の電線を保持させた実施形態を示すものである。
【００１４】
図１において符号１は電線３を保持するための基板部（電線保持部）、２は、基板部１の一方に設けられた係止用クリップをそれぞれ示す。基板部１の表面側に沿って細径な電線３が真直に載置され、基板部１の長手方向の前半側において電線３が合成樹脂製のバンド（結束手段）４で巻回固定され、且つバンド４の前後において高く突出した各電線ガイド部５の内側に沿って位置している。係止用クリップ２は基板部１の後半側において基板部１の裏面側に突出されている。
【００１５】
図１のＡ−Ａ断面を図２に示す如く、基板部１の表面側の幅方向中央に断面山型状の凸状部６が一体に突出形成され、凸状部６の両側に細径な電線３，３が一本づつ配置されている。凸状部６の突出高さは基板部１の板厚と較べて同程度ないしは若干小さい程度であり、且つ細径な電線３の径と較べて同程度ないしやや小さい程度である。凸状部６の両側の傾斜面６ａはなだらかな比較的緩い勾配で形成され、両傾斜面６ａは基板部１の表面１ａに小さな傾斜角度で交差している。凸状部６の横幅は基板部１の横幅のほぼ１／３程度ないしはそれよりもやや大きい程度である。凸状部６の頂部６ｂは滑らかに湾曲している。基板部１の両端は上向きのテーパ状に面取り（７）されている。
【００１６】
凸状部６の傾斜面６ａと基板部１の表面との交差部８上に細径な電線３が位置し、電線３の外周面の一部が凸状部６の傾斜面６ａに接し、他の一部が基板部１の表面１ａに接している。凸状部６によって少なくとも二本の電線３が左右両側に分離されている。
【００１７】
このように、基板部１の中央のスペースが凸状部６によって埋められて、電線３が基板部１の中央ではなく両側寄りに位置することで、バンド４を巻回した際に、バンド４が略長円形ないし略三角形になってバンド４の両側の傾斜部分４ａの内周面が両側の電線３の外周面に強く接して、細径な電線３の保持が確実に行われる。この際、基板部両側のテーパ状の傾斜面７はバンド４をなるべく扁平に変形させることに寄与している。
【００１８】
また、凸状部６の電線径方向外側に位置する電線ガイド部５によって細径な電線３が凸状部６の傾斜面６ａと電線ガイド部５の内側の湾曲面５ａとに接して位置ずれなく安定に保持されている。電線ガイド部５については後で詳しく説明する。
【００１９】
バンド４は従来同様に帯状の本体９と、本体９の基端に一体に設けられた係止用の枠部４０とで構成され、例えば本体９に長手方向に複数の突起（図示せず）が配列され、枠部４０内に、突起に係合する可撓性の係止爪（図示せず）が突設されている。
【００２０】
図２で符号１０は上側の基板部１に下側の基板部１１を開閉自在に連結する薄肉のヒンジ部、１２は下側の基板部１１を上側の基板部１に係止させるための係合枠片をそれぞれ示す。
【００２１】
図１に戻って、下側の基板部１１に従来同様の係止用クリップ２が一体に形成されている。係止用クリップ２は基板部１１から突出した支柱部１３（図４）と、支柱部１３の先端から傾斜して形成された一対の可撓性の係止爪１４と、係止爪１４に対向して位置する皿ばね状の弾性部１５とで構成されている。一対の係止爪１４を車両等のパネルの孔（図示せず）に挿入し、係止爪１４と弾性部１５との間にパネル（図示せず）を挟着させることで、電線クランプ５０がパネルに固定される。
【００２２】
なお、図２において凸状部６の両側でなく何れか片側のみに細径の電線３を配置した場合にも、その電線３が凸状部６の片側の傾斜面６ａに接して押し上げられるから、バンド４による電線３の締付保持を確実に行うことができる。勿論、凸状部６の左右両側に少なくとも各一本の電線３を分離して配置した場合に、一層高い電線保持力が発揮されることは言うまでもない。
【００２３】
図３〜図５は、本発明に係る電線クランプ５０において多数本の電線１６（本例では細線と太線が混合している）を保持させた実施形態を示すものである。電線クランプ５０自体の構造は図１〜図２と同様であるので、同一の符号を用いて主要部以外の説明は省略する。
【００２４】
図３の如く、上側の基板部１の表面側に多数本の電線１６が配置され、基板部１の裏面側で下側の基板部１１に複数本の電線１７が並列に配索された状態で、両群の電線１６，１７が上側の基板部１の前後（電線方向の前後）の電線ガイド部５，５の間で一本のバンド４で結束固定される。下側の電線１７は本発明と特に関係はない。上側の基板部１には前後の電線ガイド部５，５の間で凸状部６が電線長手方向に設けられている。
【００２５】
図４に示す如く、上側の基板部１の前端１ｂの両側部分に略山形状の左右一対の電線ガイド部５，５が中央の凸状部６よりも高く突出形成され、図３，図５の如く、基板部１の長手方向中間部において前端側の電線ガイド部５，５に対向して同じ型状及び高さの一対の電線ガイド部５，５が突出形成されている。前後各一対の電線ガイド部５，５の間で且つ左右各一対の電線ガイド部５，５の中間に凸状部６が位置している。本形態の電線ガイド部５の突出高さは凸状部６の突出高さのほぼ三倍程度であり、電線ガイド部５の横幅は凸状部６の横幅のほぼ二倍程度である。
【００２６】
図４の如く電線ガイド部５は内側の湾曲面５ａと外側の傾斜面５ｂと湾曲状の頂部５ｃとを有している。外側の傾斜面５ｂは図５の如く基板部１の両側端１ｃよりも外側に突出して、前後の電線ガイド部５，５の突出部分５ｄの間に凹部１８が形成され、凹部１８の間でバンド４を容易に装着可能である。電線ガイド部５の内側の湾曲面５ａは凸状部６の山型状の傾斜面６ａにほぼ湾曲形状に交差している。図４の形態では電線ガイド部５の正面壁（符号１ｂで代用）と一体に凸状部６を形成しているが、正面壁１ｂの直近（内側面）で凸状部６を終端させることも可能である。
【００２７】
図４の如く電線ガイド部５の内側の湾曲面５ａは真直な傾斜面（図示せず）の場合に較べて若干凹状に切欠され、且つ中央の凸状部６よりも高く突出しており、複数の電線１６を外側に落とすことなく（電線１６の逃げやばらけを起こすことなく）、左右の電線ガイド部５，５の内側に安定に仮置き可能である。それによりバンド締め作業を容易に行うことができる。仮置き後にバンド４を締めて電線１６を作業性良く保持（固定）させることができる。
【００２８】
バンド４を締めることで電線１６が電線ガイド部５の内側の湾曲面５ａに押接して、湾曲面５ａを外向きに強く押圧することで、その反力で電線１６が内向きに強く押し返されて、バンド４の内側に高い保持力で安定に保持される。また、中央の凸状部６は電線１６を押し上げるから、前記実施形態と同様に電線１６とバンド４との間に隙間が生じず、バンド４による電線１６の固定が高い保持力で確実に行われる。電線１６が電線ガイド部５の内側の湾曲面５ａや凸状部６の山型の傾斜面６ａと広い面積で接触するから、電線保持の信頼性が向上する。
【００２９】
図４で下側の基板部１１の内側の凹部１９内に複数の電線１７（図３）が並列に配置され、図３の如く上側の電線１６と共にバンド４で締め付け固定される。図５の如く上側の基板部１の前半に前後各一対の電線ガイド部５，５と幅方向中央の凸状部６とが配置され、上側の基板部１の後半に薄肉のヒンジ部１０を介して下側の基板部１１が開閉自在に連結されている。ヒンジ部１０とは１８０゜反対側において図３の如く上側の基板部１に係合枠片（係止手段）１２が垂下形成され、下側の基板部１１に、係合枠片１２に対する係止突起（係止手段）２０が設けられている。下側の基板部１１に係止用クリップ２が設けられている。
【００３０】
複数本の電線１６を電線ガイド部５，５に沿って仮置きさせ、バンド４を締めて電線１６を基板部１に固定させ、その後、係止用クリップ２を車両のパネルの孔（図示せず）に挿入係合させることで、複数本の電線１６すなわちワイヤハーネスが結束された状態で効率的にパネルに固定される。
【００３１】
なお、上記電線ガイド部５の内側の湾曲面５ａに代えて真直な傾斜面や略「く」の字状に屈曲した傾斜面（図示せず）を形成することも可能である。また、電線ガイド部５を基板部１の両側ではなく片側のみに設けることも可能である。また、合成樹脂製のバンド４に代えて金属製のバンドを用いることも可能である。バンド４の形状は適宜設定可能である。また、本発明は、下側の基板部１１や下側の電線１７を有しない電線クランプとしても適用可能である。また、係止用クリップ２に代えて基板部１をボルト等の他の固定手段（図示せず）で車両のパネル等に固定することも可能である。
【００３２】
【発明の効果】
以上の如く、請求項１記載の発明によれば、例えば二本の細径な電線が凸状部の両側に離れて位置するから、バンド等の結束手段（結束部材）で電線を基板部に結束する際に、結束手段が扁平にならず略長円形ないし略三角形になって基板部の中央に隙間を生じても、結束手段の両側の傾斜状の部分が電線に接して電線を基板部に確実に押圧保持する。これにより、細径の電線を少数本保持する場合でも、バンド等の結束手段で電線を確実に保持させることができる。また、細径の電線を用いた場合に、電線が凸状部で押し上げられて、バンド等の結束手段と電線との間の隙間が防止されるから、これによっても電線の保持性が向上する。また、電線が基板部の表面と凸状部の傾斜面との二面で同時に接して位置決めされるから、電線の位置ずれが防止され、電線の保持性が向上する。
また、凸状部と電線ガイド部との間に電線が挟まれるようにして位置し、電線の外側への移動が電線ガイド部で阻止され、電線の内側への移動が凸状部で阻止されるから、電線の保持性及び位置決め性が向上する。また、電線ガイド部の内側に電線を容易に仮置き（セット）することができるから、結束手段での電線の保持作業が容易化し、作業性が向上する。また、電線ガイド部による電線の仮置き性が向上すると共に、電線の本数や径の増加に対応でき、多数本の電線を強い保持力で確実に保持させることができる。また、結束手段で電線を基板部に固定した際に、電線ガイド部の内側の湾曲面に電線が強く押接し、電線に内向きの反力が作用して、電線の保持力が高まるから、電線の保持性が向上する。また、両側の電線ガイド部の間に複数本の電線を簡単且つ確実に仮置きでき、且つ両側の電線ガイド部の間で複数本の電線を結束手段で確実に締め付け保持させることができる。
【００３３】
請求項２記載の発明によれば、基板部の両側の傾斜面が結束手段であるバンドをなるべく扁平に変形させることに寄与し、細径な電線の保持が確実に行われる。
【００３６】
請求項３記載の発明によれば、電線ガイド部による電線の仮置き性が向上すると共に、電線の本数や径の増加に対応でき、多数本の電線を強い保持力で確実に保持させることができる。
【００３８】
請求項４記載の発明によれば、特に細径の電線が電線ガイド部と凸状部との交差部上に位置して、凸状部の傾斜面と電線ガイド部の湾曲面とに同時に二点接触するから、電線の位置決め性及び保持性が向上する。

BACKGROUND OF THE INVENTION
The present invention relates to an electric wire clamp capable of reliably holding an electric wire by a binding means such as a band.
[0002]
[Prior art]
FIG. 6 shows one form of a conventional wire clamp.
The electric wire clamp 51 is formed integrally with a synthetic resin substrate portion 54 for fixing a wire harness, which is a plurality of electric wires 52, by a band 53 or tape winding, and one end side of the substrate portion 54, and is used for a vehicle panel or the like. And a locking clip 55 inserted and locked in a hole (not shown).
[0003]
At the other end of the substrate portion 54, a protruding protrusion 56 is integrally formed, and the substrate portion 54 can be fixed to the wire harness 52 without misalignment. Not only a plurality of electric wires 52 but also a single electric wire can be fixed to the substrate portion 54. The band 53 is formed in a band shape using a synthetic resin as a material, and includes a band main body 57 and a locking frame portion 58 provided integrally with the base end of the band main body 57.
[0004]
[Problems to be solved by the invention]
However, in the conventional electric wire clamp 51, when fixing the electric wire 52 by tape winding, many man-hours are required and it is difficult to automate the tape winding. The electric wire 52 is fixed by using the resin band 53. In this case, as shown in FIG. 7, the thick wire harness 52 and the electric wire can be strongly fixed to the substrate portion. However, as shown in FIG. 8, for the thin wire 59, the band 53 is difficult to be flattened, so that a gap 60 is easily generated between the band 53 and the wire 52, and the holding force of the wire 59 is weak. There was a concern that the electric wire 59 would be rattled due to insufficient holding, causing wear and damage. In addition, there is a problem that the substrate portion 54 is flat and it is difficult to temporarily place the electric wires 59, and the fixing workability of the electric wires 59 is poor.
[0005]
In view of the above-described points, the present invention provides a wire clamp that can be firmly tightened and fixed with a strong force without looseness as well as a thick wire as well as a thick wire, and can improve the workability of fixing the wire. The purpose is to do.
[0006]
[Means for Solving the Problems]
To achieve the above object, the wire clamp according to claim 1 of the present invention, the wire clamp to fix the wire in the binding member by winding the bundling member to the substrate portion, the widthwise center of the substrate portion , A convex portion having a mountain-shaped cross section along the longitudinal direction of the electric wire is formed, and the electric wires are separately disposed on the left and right sides of the convex portion, and the front and rear ends of the convex portion in the longitudinal direction of the electric wire Each pair of wire guide portions protrudes on both the left and right sides of the substrate portion, each wire guide portion has a curved surface on the inside, and the binding member is disposed between the pair of front and rear wire guide portions, The outer width of the substrate portion is set wider than the inner width of the curved surface of the wire guide portion .
With the above configuration, since there is a convex portion in the center of the width direction of the substrate portion, the electric wire is not located in the center of the substrate portion. For example, two electric wires are located on both sides of the convex portion, so the band When bundling the wires with the bundling means (bundling member), etc., even if the bundling means does not become flat but becomes a substantially oval or a substantially triangular shape and creates a gap in the center of the board, The slanted portion of the contact is in contact with the electric wire and securely presses and holds the electric wire on the substrate portion. In particular, when a small-diameter electric wire is used, the electric wire is pushed up by the convex portion to prevent a gap between the binding means such as a band and the electric wire, and the electric wire is securely held by the binding means. . Further, since the electric wire is positioned in contact with the two surfaces of the surface of the substrate portion and the inclined surface of the convex portion at the same time, the electric wire is prevented from being displaced and the electric wire retainability is improved.
Also, the wire is positioned so that the electric wire is sandwiched between the convex portion and the wire guide portion, the movement of the electric wire to the outside is blocked by the wire guide portion, and the movement of the electric wire to the inside is blocked by the convex portion. As a result, the retention and positioning of the electric wire are improved. Moreover, the electric wire can be easily temporarily placed (set) inside the electric wire guide portion, and the work of holding the electric wire in the bundling means is facilitated.
Further, when the electric wire is fixed to the substrate portion by the bundling means, the electric wire strongly presses against the curved surface on the inner side of the electric wire guide portion, and an inward reaction force acts on the electric wire, thereby increasing the holding force of the electric wire.
In addition, a plurality of wires are securely placed between the wire guide portions on both sides, and then the plurality of wires are securely clamped and held by the bundling means between the wire guide portions on both sides. A reaction force toward the fastening center acts on each electric wire, and the electric wire retainability is improved.
[0007]
Wire clamp according to claim 2 is the wire clamp according to claim 1, in the width direction end sides of the base plate portion, inclined surface inclined in the same direction as the convex portion is formed, the binding member is the It contacts the inclined surface and the electric wire at the same time.
[0010]
An electric wire clamp according to a third aspect is the electric wire clamp according to the first or second aspect , wherein the electric wire guide portion protrudes higher than the convex portion.
With the above configuration, the temporary placement of the electric wire by the electric wire guide portion is improved, and the increase in the number and the diameter of the electric wires can be coped with, so that the electric wire retainability is improved.
[0012]
An electric wire clamp according to a fourth aspect is the electric wire clamp according to any one of the first to third aspects, wherein the curved surface on the inner side of the electric wire guide portion intersects the inclined surface of the convex portion, the angle between the inner curved surface of the inclined surface of the convex portion and the electric wire guide portion is smaller than the angle between the inclined surface of the convex portion and the substrate portion, the inclined surface of the convex portion and the The electric wire simultaneously contacts a curved surface inside the electric wire guide portion.
With the above configuration, a particularly small-sized electric wire is located on the intersection of the electric wire guide portion and the convex portion, and simultaneously contacts the inclined surface of the convex portion and the curved surface of the electric wire guide portion. This improves the positioning and holding performance.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1 to 2 show an embodiment in which a small number of small-diameter electric wires are held in the electric wire clamp according to the present invention.
[0014]
In FIG. 1, reference numeral 1 denotes a substrate portion (electric wire holding portion) for holding the electric wire 3, and 2 denotes a locking clip provided on one side of the substrate portion 1. A thin electric wire 3 is placed straight along the surface side of the substrate portion 1, and the electric wire 3 is wound and fixed by a synthetic resin band (binding means) 4 on the first half side in the longitudinal direction of the substrate portion 1, And it is located along the inner side of each electric wire guide part 5 protruded highly before and behind the band 4. The locking clip 2 protrudes on the back side of the substrate part 1 on the latter half side of the substrate part 1.
[0015]
As shown in FIG. 2, the AA cross section of FIG. 1 has a convex portion 6 having a mountain-shaped cross section integrally formed at the center in the width direction on the surface side of the substrate portion 1. Wires 3 and 3 are arranged one by one. The protruding height of the convex portion 6 is approximately the same as or slightly smaller than the plate thickness of the substrate portion 1, and is approximately the same or slightly smaller than the diameter of the thin wire 3. The inclined surfaces 6 a on both sides of the convex portion 6 are formed with a gentle and relatively gentle gradient, and both inclined surfaces 6 a intersect the surface 1 a of the substrate portion 1 with a small inclination angle. The lateral width of the convex portion 6 is about 1/3 of the lateral width of the substrate portion 1 or slightly larger than that. The top portion 6b of the convex portion 6 is smoothly curved. Both ends of the substrate portion 1 are chamfered (7) in an upward tapered shape.
[0016]
The thin wire 3 is positioned on the intersection 8 between the inclined surface 6a of the convex portion 6 and the surface of the substrate portion 1, and a part of the outer peripheral surface of the electric wire 3 is in contact with the inclined surface 6a of the convex portion 6, The other part is in contact with the surface 1 a of the substrate part 1. At least two electric wires 3 are separated on the left and right sides by the convex portion 6.
[0017]
Thus, when the band 4 is wound, the central space of the board part 1 is filled with the convex part 6 and the electric wires 3 are located not on the center of the board part 1 but on both sides. Becomes substantially oval or substantially triangular, and the inner peripheral surfaces of the inclined portions 4a on both sides of the band 4 are in strong contact with the outer peripheral surfaces of the electric wires 3 on both sides, so that the small-diameter electric wires 3 are securely held. At this time, the tapered inclined surfaces 7 on both sides of the substrate portion contribute to deforming the band 4 as flat as possible.
[0018]
Further, the electric wire guide portion 5 located on the outer side of the convex portion 6 in the electric wire radial direction causes the thin electric wire 3 to contact the inclined surface 6a of the convex portion 6 and the curved surface 5a on the inner side of the electric wire guide portion 5 to be displaced. It is held stably. The wire guide portion 5 will be described in detail later.
[0019]
The band 4 is configured by a band-shaped main body 9 and a locking frame 40 integrally provided at the base end of the main body 9 as in the prior art. For example, the band 4 has a plurality of protrusions (not shown) in the longitudinal direction. Are arranged, and a flexible locking claw (not shown) that engages with the protrusion protrudes in the frame portion 40 .
[0020]
In FIG. 2, reference numeral 10 denotes a thin hinge portion that connects the lower substrate portion 11 to the upper substrate portion 1 so that the lower substrate portion 11 can be freely opened and closed, and 12 denotes an engagement for locking the lower substrate portion 11 to the upper substrate portion 1. Each frame piece is shown.
[0021]
Returning to FIG. 1, the same locking clip 2 is formed integrally with the lower substrate portion 11. The locking clip 2 includes a support column 13 (FIG. 4) protruding from the base plate 11, a pair of flexible locking claws 14 formed to be inclined from the tip of the support column 13, and the locking claws 14.

[0022]
In addition, even when the thin wire 3 is arranged on only one side of the convex portion 6 in FIG. 2, the electric wire 3 is pushed up in contact with the inclined surface 6 a on one side of the convex portion 6. The wire 3 can be securely clamped and held by the band 4. Needless to say, when at least one electric wire 3 is separately disposed on both the left and right sides of the convex portion 6, it is needless to say that a higher electric wire holding force is exhibited.
[0023]
3 to 5 show an embodiment in which a large number of electric wires 16 (in this example, fine wires and thick wires are mixed) are held in an electric wire clamp 50 according to the present invention. Since the structure of the electric wire clamp 50 itself is the same as that of FIGS. 1-2, description other than a main part is abbreviate | omitted using the same code | symbol.
[0024]
As shown in FIG. 3, a large number of electric wires 16 are arranged on the front surface side of the upper substrate portion 1, and a plurality of electric wires 17 are arranged in parallel on the lower substrate portion 11 on the back surface side of the substrate portion 1. Thus, the electric wires 16 and 17 of both groups are bound and fixed by a single band 4 between the electric wire guide portions 5 and 5 before and after the upper substrate portion 1 (front and rear in the electric wire direction). The lower electric wire 17 is not particularly related to the present invention. On the upper substrate portion 1, a convex portion 6 is provided between the front and rear wire guide portions 5, 5 in the longitudinal direction of the wire.
[0025]
As shown in FIG. 4, a pair of left and right wire guide portions 5, 5 having a substantially mountain shape are formed on both side portions of the front end 1 b of the upper substrate portion 1 so as to protrude higher than the central convex portion 6. As described above, a pair of wire guide portions 5 and 5 having the same shape and height are formed so as to be opposed to the wire guide portions 5 and 5 on the front end side in the intermediate portion in the longitudinal direction of the substrate portion 1. The convex portion 6 is positioned between the pair of front and rear electric wire guide portions 5 and 5 and in the middle of the pair of left and right electric wire guide portions 5 and 5. The protruding height of the wire guide portion 5 of this embodiment is about three times the protruding height of the convex portion 6, and the horizontal width of the wire guide portion 5 is about twice the horizontal width of the convex portion 6.
[0026]
As shown in FIG. 4, the wire guide portion 5 has an inner curved surface 5a, an outer inclined surface 5b, and a curved top portion 5c. As shown in FIG. 5, the outer inclined surface 5 b protrudes outward from both side ends 1 c of the substrate portion 1, and a recess 18 is formed between the protruding portions 5 d of the front and rear wire guide portions 5, 5. The band 4 can be easily attached. The curved surface 5 a on the inner side of the electric wire guide portion 5 intersects with the mountain-shaped inclined surface 6 a of the convex portion 6 in a substantially curved shape. In the form of FIG. 4, the convex portion 6 is formed integrally with the front wall of the wire guide portion 5 (substitute with reference numeral 1 b), but the convex portion 6 is terminated in the immediate vicinity (inner side surface) of the front wall 1 b. Is also possible.
[0027]
As shown in FIG. 4, the curved surface 5a on the inner side of the wire guide portion 5 is slightly recessed as compared with a straight inclined surface (not shown), and protrudes higher than the central convex portion 6. Can be stably and temporarily placed inside the left and right wire guide portions 5 and 5 without dropping the wire 16 outside (without causing the wire 16 to escape or scatter). Thereby, the band fastening operation can be easily performed. The band 4 can be tightened after temporary placement to hold (fix) the electric wire 16 with good workability.
[0028]
By tightening the band 4, the electric wire 16 is pressed against the curved surface 5 a on the inner side of the electric wire guide portion 5, and the curved surface 5 a is strongly pressed outward, whereby the electric wire 16 is strongly pushed back inward by the reaction force. Thus, it is stably held with high holding force inside the band 4. Further, since the central convex portion 6 pushes up the electric wire 16, no gap is formed between the electric wire 16 and the band 4 as in the above-described embodiment, and the fixing of the electric wire 16 by the band 4 is reliably performed with a high holding force. Is called. Since the electric wire 16 contacts the curved surface 5a on the inner side of the electric wire guide portion 5 and the mountain-shaped inclined surface 6a of the convex portion 6 in a wide area, the reliability of electric wire holding is improved.
[0029]
In FIG. 4, a plurality of electric wires 17 (FIG. 3) are arranged in parallel in the concave portion 19 inside the lower substrate portion 11, and are fastened and fixed by the band 4 together with the upper electric wire 16 as shown in FIG. 3. As shown in FIG. 5, a pair of front and rear wire guide portions 5, 5 and a convex portion 6 at the center in the width direction are disposed in the first half of the upper substrate portion 1, and a thin hinge portion 10 is disposed in the second half of the upper substrate portion 1. The lower substrate portion 11 is connected to be freely opened and closed. As shown in FIG. 3, an engagement frame piece (locking means) 12 is suspended from the hinge portion 10 on the side opposite to the hinge portion 10 as shown in FIG. 3, and the lower substrate portion 11 is engaged with the engagement frame piece 12. A stop projection (locking means) 20 is provided. The locking clip 2 is provided on the lower substrate portion 11.
[0030]
A plurality of wires 16 are temporarily placed along the wire guide portions 5 and 5, the band 4 is tightened to fix the wires 16 to the substrate portion 1, and then the locking clip 2 is attached to a hole (not shown) in the vehicle panel. 2), the plurality of electric wires 16, that is, the wire harnesses, are efficiently fixed to the panel in a bundled state.
[0031]
Instead of the curved surface 5a on the inner side of the wire guide portion 5, a straight inclined surface or an inclined surface (not shown) bent in a substantially “<” shape can be formed. It is also possible to provide the wire guide part 5 only on one side, not on both sides of the board part 1. Further, a metal band can be used instead of the synthetic resin band 4. The shape of the band 4 can be set as appropriate. The present invention is also applicable as a wire clamp that does not have the lower substrate portion 11 or the lower wire 17. Moreover, it is also possible to fix the board | substrate part 1 to the panel etc. of a vehicle with another fixing means (not shown), such as a volt | bolt, instead of the clip 2 for latching.

【The invention's effect】
As described above, according to the first aspect of the present invention, for example, two small-diameter electric wires are located on both sides of the convex portion, so the electric wires are connected to the substrate portion by a binding means (bundling member) such as a band. Even when the binding means is not flattened and becomes a substantially oval or a triangular shape and a gap is formed in the center of the board part, the inclined portions on both sides of the binding means are in contact with the electric wire and the electric wire is connected to the board part. Press and hold securely. Thereby, even when a small number of thin wires are held, the wires can be reliably held by a binding means such as a band. In addition, when a small-diameter electric wire is used, the electric wire is pushed up by the convex portion, and a gap between the binding means such as a band and the electric wire is prevented, which also improves the electric wire retainability. . Further, since the electric wire is positioned in contact with the two surfaces of the surface of the substrate portion and the inclined surface of the convex portion at the same time, the electric wire is prevented from being displaced and the electric wire retainability is improved.
Also, the wire is positioned so that the electric wire is sandwiched between the convex portion and the wire guide portion, the movement of the electric wire to the outside is blocked by the wire guide portion, and the movement of the electric wire to the inside is blocked by the convex portion. Therefore, the retainability and positioning properties of the electric wire are improved. Further, since the electric wire can be temporarily placed (set) inside the electric wire guide part, the work of holding the electric wire by the bundling means is facilitated and the workability is improved. Moreover, while the temporary placement property of the electric wire by an electric wire guide part improves, it can respond to the increase in the number and diameter of an electric wire, and can hold many electric wires reliably with strong holding force. In addition, when the electric wire is fixed to the board portion by the bundling means, the electric wire strongly presses against the inner curved surface of the electric wire guide portion, and an inward reaction force acts on the electric wire, thereby increasing the holding force of the electric wire. Wire retainability is improved. In addition, a plurality of wires can be temporarily and reliably placed between the wire guide portions on both sides, and the plurality of wires can be securely clamped and held between the wire guide portions on both sides by the bundling means.
[0033]
According to the second aspect of the present invention, the inclined surfaces on both sides of the substrate portion contribute to deforming the band as the bundling means as flat as possible, so that the small-diameter electric wire is reliably held.
[0036]
According to the third aspect of the invention, the temporary placement of the electric wire by the electric wire guide portion is improved, it is possible to cope with an increase in the number and diameter of the electric wires, and a large number of electric wires can be securely held with a strong holding force. it can.
[0038]
According to the invention described in claim 4 , a particularly small-diameter electric wire is located on the intersection of the wire guide portion and the convex portion, and is simultaneously applied to the inclined surface of the convex portion and the curved surface of the wire guide portion. Since it makes point contact, the positioning and holding properties of the electric wire are improved.
