【発明の属する技術分野】
本発明は、ワイヤーハーネスを所定の配索経路に沿って配索するためにワイヤーハーネスを保持するようにしたワイヤーハーネス保持構造に関する。
【０００２】
【従来の技術】
この種のワイヤーハーネス保持構造として、図６〜図８に示す実開平７−１０６６９号公報に開示されたものがある。このワイヤーハーネス保持構造は、図６〜図８に示すように、ワイヤーハーネスＷをテーピング部１等で拘束したクリップ２を有し、このクリップ２に係止突起３が設けられている。車体内板等の基板４にはブラケット５が溶接により固定され、このブラケット５には係止長孔６が設けられている。
【０００３】
そして、クリップ２の係止突起３をブラケット５の係止長孔６に挿入すると、係止突起３が弾性変形により縮径して係止長孔６に入り、挿入完了位置で係止突起３が弾性復帰変形してブラケット５に係止されることによってワイヤーハーネスＷが基板４に保持されるようになっている。
【０００４】
このようなワイヤーハーネス保持構造によれば、クリップ２の係止突起３をブラケット５の係止長孔６に単に挿入することによってワイヤーハーネスＷを保持することができるという利点がある。
【０００５】
【発明が解決しようとする課題】
しかしながら、前記従来のワイヤーハーネス保持構造では、クリップ２の係止突起３をブラケット５の係止長孔６に挿入する際に、ワイヤーハーネスＷや図示しない周囲の設置部品が作業者の視界を遮り係止長孔６が見え難い状態、或いは全く見えない状態で挿入作業をしなければならない場合が多々あり、このような状況下では係止突起３の挿入作業が容易にできないという問題があった。
【０００６】
そこで、本発明は、前記した課題を解決すべくなされたものであり、ワイヤーハーネスや周囲の設置部品が作業者の視界を遮り係止長孔が見え難い、或いは、全く見えない場合であっても、係止突起の係止孔への挿入作業を容易に行うことができるワイヤーハーネス保持構造を提供することを目的とする。
【０００７】
【課題を解決するための手段】
請求項１の発明は、ワイヤーハーネスを拘束するクリップに係止突起を設け、前記ワイヤーハーネスを所定の配索経路に沿って配索するように前記ワイヤーハーネスを保持するハーネス保持部材に係止孔を設け、この係止孔に前記係止突起を挿入し、この挿入完了位置で前記係止突起が係止されることによって前記ワイヤーハーネスが前記ハーネス保持部材に保持されるようにしたワイヤーハーネス保持構造において、前記ハーネス保持部材の前記ハーネス保持部材の２箇所以上に係止孔をそれぞれ設け、この１箇所の係止孔を円孔形状に、他の係止孔をハーネス配索方向に沿って延びる長孔形状に、それぞれ形成し、かつ、前記各係止孔の周囲に、該各係止孔に近付くに従って徐々に深さが深くなる挿入ガイド面を設ける一方、前記ハーネス保持部材に前記ワイヤーハーネスを収容し、この収容した前記ワイヤーハーネスの３方向を囲むハーネス収容室を設け、このハーネス収容室の開口側に対して奥の対向面は、ストレートに延びるストレート面と、このストレート面に対して前記ハーネス収容室の開口側に傾斜する傾斜面とを有し、前記ストレート面に前記円孔形状の係止孔を、前記傾斜面に前記長孔形状の係止孔を、それぞれ形成したことを特徴とする。
【０００８】
このワイヤーハーネス保持構造では、ワイヤーハーネスを２つ以上のクリップで拘束し、各クリップの係止突起を２箇所以上の係止孔にそれぞれ挿入する際に、複数のクリップ間の長さが複数の係止孔間の長さと多少異なった場合でも各係止突起の各係止孔への挿入作業ができる。特に、各係止突起が各係止孔よりずれた位置に挿入された場合に、各係止突起が挿入ガイド面に当接し、挿入ガイド面の傾斜で各係止孔に向かってガイドされることから各係止突起が各係止孔に導かれる。また、３方向がハーネス保持部材に囲まれた状態でワイヤーハーネスが保持され、ハーネス収容室の比較的に見え易いストレート面の係止孔を円孔形状に、ストレート面の係止孔より見え難い傾斜面の係止孔を長孔形状としたことにより、クリップの係止突起の挿入作業性の向上になる。さらに、ストレート面の係止孔より見え難い方を傾斜面としたことにより、傾斜面の係止孔に対してクリップの係止突起の挿入力が加え易くなり、その分、ワイヤーハーネスの組付作業性の向上になる。
【００１５】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
【００１６】
図１〜図５は本発明の一実施形態を示し、図１はアンダーカバーの斜視図、図２は上面壁を切り欠いたアンダーカバーの斜視図、図３はクリップの係止突起をアンダーカバーの係止孔に挿入する前の状態を示す斜視図、図４はクリップの係止突起をアンダーカバーの係止孔に挿入した状態を示す斜視図、図５（ａ）はクリップの係止突起がアンダーカバーの挿入ガイド面に当接した状態を示す断面図、図５（ｂ）はクリップの係止突起がアンダーカバーの係止孔に挿入された状態を示す断面図である。
【００１７】
図１〜図４に示すように、複数の電線の束のワイヤーハーネスＷの適所にはクリップ１０が装着され、この各クリップ１０はワイヤーハーネスＷを一塊りに拘束する拘束バンド部１１と、この拘束バンド部１１に連結された係止突起１２とを有している。図５（ａ），（ｂ）に示すように、各クリップ１０の係止突起１２は、ロッド部１２ａと、このロッド部１２ａの先端から手前に向かって広がる方向に延設された一対の弾性係止腕部１２ｂ，１２ｂとからなり、各弾性係止腕部１２ｂが中心方向に向かう外力を受けると、縮径方向に弾性変形可能になっている。
【００１８】
電気接続箱（図示省略）は、電気回路を内蔵した電気接続本体部と、この電気接続本体部を内部に収容するカバー１３とから構成されている。電気接続本体部は、その上面側にヒューズなどの電子部品が装着されると共に下面側にワイヤーハーネスＷの端部が接続される。カバー１３は、例えば電気接続本体部の上面側を被うアッパーカバーと電気接続本体部の側面を被うように配置されたサイドカバーと電気接続本体部の底面を被い、ハーネス保持部材であるアンダーカバー１４とが組み付けられることにより構成され、アンダーカバー１４を介して車体内板（いずれも図示省略）に固定されている。
【００１９】
アンダーカバー１４の下方には、底面壁１５とこの底面壁１５より立設された側面壁１６とこの側面壁１６の上端に配置された上面壁１７とが設けられ、これらによってワイヤーハーネスの３方向を囲むハーネス収容室１８が形成されている。このハーネス収容室１８は、ワイヤーハーネスＷの配索経路の一部とされ、ここに配索されたワイヤーハーネスＷの端部がアンダーカバー１４よりカバー１３内の下方に導き入れられている。
【００２０】
ハーネス収容室１８の開口側に対して奥に配置される対向面（側面壁１６の面）は、ストレートに延びるストレート面１６ａと、このストレート面１６ａに対してハーネス収容室１８の開口側に傾斜する傾斜面１６ｂとを有し、ストレート面１６ａと傾斜面１６ｂとには係止孔１９，２０がそれぞれ形成されている。この各係止孔１９，２０の全周囲には、係止孔１９，２０に近付くに従って徐々に深さが深くなる円錐面状の挿入ガイド面２１が設けられている。ストレート面１６ａの係止孔１９は円孔形状に、傾斜面１６ｂの係止孔２０はハーネス配索方向に沿って延びる長孔形状に、それぞれ形成されている。
【００２１】
次に、上記ワイヤーハーネス保持構造におけるワイヤーハーネスＷの保持作業について説明する。各クリップ１０の拘束バンド部１１によってワイヤーハーネスＷの適所をそれぞれ拘束する。ここで、２箇所のクリップ１０の間隔は、ストレート面１６ａの係止孔１９と傾斜面１６ｂの係止孔２０との間隔になるようにする。次に、ワイヤーハーネスＷに装着された各クリップ１０の係止突起１２を前方にしてワイヤーハーネスＷをアンダーカバー１４のハーネス収容室１８に挿入する。そして、各クリップ１０の係止突起１２を各係止孔１９，２０に位置合わせして挿入する。
【００２２】
ここで、係止突起１２が係止孔１９，２０の位置に一致する場合には、係止突起１２が直ちに係止孔１９，２０に挿入される。係止孔１９，２０に挿入された係止突起１２は、その弾性係止腕部１２ｂが縮径方向に弾性変形することにより係止孔１９，２０の奥への挿入が許容され、挿入完了位置まで挿入されると弾性係止腕部１２ｂが弾性復帰変形し、これにより係止突起１２が側面壁１６に係止される（図５（ｂ）の状態）。
【００２３】
また、図５（ａ）に示すように、各クリップ１０の係止突起１２が係止孔１９，２０の位置よりずれた場合には、係止突起１２の先端が挿入ガイド面２１に当接される。係止突起１２がこの状態より更に挿入されると、係止突起１２が挿入ガイド面２１の傾斜によって徐々に係止孔１９，２０に向かってガイドされ、最終的に係止孔１９，２０に挿入される。係止孔１９，２０に挿入された係止突起１２は、前述したように、その弾性係止腕部１２ｂが縮径方向に弾性変形することにより係止孔１９，２０の奥への挿入が許容され、挿入完了位置まで挿入されると弾性係止腕部１２ｂが弾性復帰変形し、これにより係止突起１２が側面壁１６に係止される（図５（ｂ）の状態）。
【００２４】
以上より、ワイヤーハーネスＷや周囲の設置部品、特に、電気接続箱のアンダーカバー１４が作業者の視界を遮り係止孔１９，２０が見え難くても、或いは、全く見えなくても係止突起１２の係止孔１９，２０への挿入作業を容易に行うことができる。
【００２５】
上記実施形態では、アンダーカバー１４の２箇所に係止孔１９，２０を設け、この１箇所の係止孔１９を円孔形状に、他の係止孔２０をハーネス配索方向に沿って延びる長孔形状に、それぞれ形成したので、ワイヤーハーネスＷを２つのクリップ１０で拘束し、各クリップ１０の係止突起１２を２箇所の係止孔１９，２０にそれぞれ挿入する際に、２つのクリップ１０間の長さが２箇所の係止孔１９，２０間の長さと多少異なった場合でも各係止突起１２の各係止孔１９，２０への挿入作業ができるため、各クリップ１０間の寸法を厳密に装着する必要がない。
【００２６】
上記実施形態では、アンダーカバー１４にワイヤーハーネスＷを収容し、この収容したワイヤーハーネスＷの３方向を囲むハーネス収容室１８を設け、このハーネス収容室１８の開口側の面に対して奥に配置される側面壁１６の面１６ａ，１６ｂに係止孔１９，２０を形成したので、３方向がアンダーカバー１４に囲まれた状態でワイヤーハーネスＷが保持されるため、配索完了されたワイヤーハーネスＷが他の部品等から干渉される事態を極力防止することができる。
【００２７】
そして、ワイヤーハーネスＷの３方向を囲むハーネス収容室１８の奥の面１６ａ，１６ｂに係止孔１９，２０が形成されており、係止突起１２の挿入作業時に係止孔１９，２０が殆ど見えない状態での挿入作業が余儀なくされるが、挿入ガイド面２１による係止突起１２のガイド作用によって係止突起１２の挿入作業を容易に行うことができる。また、側面壁１６のストレート面１６ａの係止孔１９より見え難い方を傾斜面１６ｂとしたことにより、この傾斜面１６ｂの係止孔２０に対してクリップ１０の係止突起１２の挿入力が加え易くなり、その分、ワイヤーハーネスＷの組付作業を容易に行うことができる。
【００２８】
以上より、ワイヤーハーネスＷの３方向を囲むハーネス収容室１８にワイヤーハーネスＷを収容した状態でワイヤーハーネスＷを保持するものにあって、係止突起１２の挿入作業を容易に行うことができる。また、電気接続箱は、上述したように、カバー１３内に収容される電気接続本体部の下方側にワイヤーハーネスＷの接続箇所が配置されており、カバー１３の下方に配置されるアンダーカバー１４の周囲にワイヤーハーネスＷを配索し、且つ、ワイヤーハーネスＷを外部から保護したいという要望があり、上記実施形態はこのような要望を満たしつつ係止突起１２の挿入を容易に行うことができるものである。
【００２９】
上記実施形態では、ハーネス収容室１８の開口側に対して奥の対向面、つまり、側面壁１６の面は、ストレートに延びるストレート面１６ａとこのストレート面１６ａに対してハーネス収容室１８の開口側に傾斜する傾斜面１６ｂとを有し、ストレート面１６ａに円孔形状の係止孔１９を、傾斜面１６ｂに長孔形状の係止孔２０を、それぞれ形成してある。即ち、比較的見え易いストレート面１６ａの係止孔１９を円孔形状に、ストレート面１６ａの係止孔１９より見え難い傾斜面１６ｂの係止孔２０を長孔形状としたため、ワイヤーハーネスＷの３方向を囲むハーネス収容室１８にワイヤーハーネスＷを収容した状態でワイヤーハーネスＷを保持するものにあって、係止突起１２の挿入作業性の向上になる。
【００３０】
特に、側面壁１６の傾斜面１６ｂの係止孔２０が見え難く、或いは、傾斜面１６ｂの係止孔２０とこれに隣接する係止孔１９との間の長さ寸法に２つのクリップ１０間の寸法を合わせ難いが、挿入ガイド面２１による係止突起１２のガイド作用と、１つの係止孔２０が長孔形状で厳格にクリップ１０間の寸法に設定しなくて良いことから係止突起１２の挿入作業を容易に行うことができる。
【００３１】
尚、前記実施形態によれば、ワイヤーハーネス保持構造を、自動車の電気接続箱の近傍箇所でワイヤーハーネスＷを保持するものに適用した場合について説明したが、自動車以外に配索されるワイヤーハーネスを保持する場合にも略同様に適用することができることは勿論である。また、前記実施形態によれば、アンダーカバーの２箇所に係止孔を設けたが、３箇所以上に係止孔を設けても良い。この場合には、１箇所の係止孔を円孔に、他の２箇所以上の係止孔を長孔に、それぞれ形成する。
【００３２】
【発明の効果】
以上説明したように、請求項１の発明によれば、ハーネス保持部材の１箇所の係止孔を円孔形状に、他の係止孔を長孔形状に、それぞれ形成したので、ワイヤーハーネスを２つ以上のクリップで拘束し、各クリップの係止突起を２箇所以上の係止孔にそれぞれ挿入する際に、複数のクリップ間の長さが複数の係止孔間の長さと多少異なった場合でも各係止突起の各係止孔への挿入作業を容易に行うことができる。従って、各クリップ間の寸法を厳密に設定する必要がない。また、ハーネス保持部材の各係止孔の周囲に所定の挿入ガイド面を設けたので、各係止突起が各係止孔よりずれた位置に挿入された場合に、各係止突起が挿入ガイド面に当接し、挿入ガイド面の傾斜で各係止孔に向かってガイドされることから各係止突起が各係止孔に導かれるため、ワイヤーハーネスや周囲の設置部品が作業者の視界を遮り係止孔が見え難い、或いは、全く見えない場合にあっても、各係止突起の各係止孔への挿入作業を容易に行うことができる。
【００３４】
また、３方向がハーネス保持部材に囲まれた状態でワイヤーハーネスが保持されるため、ワイヤーハーネスが他の部品等から干渉される事態を極力防止することができる。そして、ワイヤーハーネスの３方向を囲むハーネス収容室の面に各係止孔が形成されており、各係止突起の挿入作業時に各係止孔が殆ど見えない状態での挿入作業が余儀なくされるが、挿入ガイド面による各係止突起のガイド作用によって各係止突起の挿入作業を容易に行うことができる。これにより、ワイヤーハーネスの３方向を囲むハーネス収容室にワイヤーハーネスを収容した状態でワイヤーハーネスを保持するものにあって、各係止突起の挿入作業を極めて容易に行うことができる。
【００３５】
特に、ハーネス収容室の比較的に見え易いストレート面の係止孔を円孔形状に、ストレート面の係止孔より見え難い傾斜面の係止孔を長孔形状としたことにより、ワイヤーハーネスの３方向を囲むハーネス収容室にワイヤーハーネスを収容した状態でワイヤーハーネスを保持するものにあってクリップの係止突起の挿入作業性をより一段と向上させることができる。また、ストレート面の係止孔より見え難い方を傾斜面としたことにより、傾斜面の係止孔に対してクリップの係止突起の挿入力が加え易くなり、その分、ワイヤーハーネスの組付作業性をより一段と向上させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a wire harness holding structure configured to hold a wire harness in order to route the wire harness along a predetermined routing route.
[0002]
[Prior art]
As this type of wire harness holding structure, there is one disclosed in Japanese Utility Model Laid-Open No. 7-10669 shown in FIGS. As shown in FIGS. 6 to 8, the wire harness holding structure has a clip 2 in which the wire harness W is restrained by a taping portion 1 or the like, and a locking projection 3 is provided on the clip 2. A bracket 5 is fixed to the substrate 4 such as an inner plate of the vehicle body by welding, and a locking elongated hole 6 is provided in the bracket 5.
[0003]
Then, when the locking protrusion 3 of the clip 2 is inserted into the locking long hole 6 of the bracket 5, the locking protrusion 3 is reduced in diameter by elastic deformation and enters the locking long hole 6, and at the insertion completion position, the locking protrusion 3 The wire harness W is held by the substrate 4 by being elastically deformed and locked to the bracket 5.
[0004]
According to such a wire harness holding structure, there is an advantage that the wire harness W can be held by simply inserting the locking protrusion 3 of the clip 2 into the locking long hole 6 of the bracket 5.
[0005]
[Problems to be solved by the invention]
However, in the conventional wire harness holding structure, when the locking projection 3 of the clip 2 is inserted into the locking long hole 6 of the bracket 5, the wire harness W and surrounding installation parts (not shown) block the operator's view. There are many cases where the insertion work must be performed in a state in which the locking long hole 6 is difficult to see or not visible at all, and there is a problem that the insertion operation of the locking projection 3 cannot be easily performed under such circumstances. .
[0006]
Therefore, the present invention has been made to solve the above-described problem, and is a case where the wire harness and surrounding installation parts obstruct the operator's field of view and it is difficult to see the locking oblong hole or not at all. Another object of the present invention is to provide a wire harness holding structure capable of easily inserting the locking protrusion into the locking hole.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, the clip for restraining the wire harness is provided with a latching projection, and the harness holding member that holds the wire harness so as to route the wire harness along a predetermined routing route is provided with a latch hole. Wire harness holding in which the wire harness is held by the harness holding member by inserting the lock protrusion into the lock hole and locking the lock protrusion at the insertion completion position. In the structure, locking holes are provided at two or more locations of the harness holding member of the harness holding member, the one locking hole is formed in a circular shape, and the other locking holes are arranged along the harness routing direction. a long hole shape extending respectively formed, and, while the surrounding of the engaging hole, Ru provided an insertion guide surface gradually depth increases as approaching the respective locking holes, said harnesses The wire harness is housed in a holding member, a harness housing chamber is provided that surrounds the three directions of the housed wire harness, and the opposing surface at the back with respect to the opening side of the harness housing chamber is a straight surface extending straightly; An inclined surface inclined toward the opening side of the harness housing chamber with respect to the straight surface, the circular hole-shaped locking hole on the straight surface, and the elongated hole-shaped locking hole on the inclined surface. , Each formed .
[0008]
In this wire harness holding structure, when the wire harness is constrained by two or more clips, and the locking projections of each clip are inserted into the two or more locking holes, the length between the plurality of clips is plural. Even when the length between the locking holes is somewhat different, the insertion work of each locking projection into each locking hole can be performed. In particular, when each locking projection is inserted at a position shifted from each locking hole, each locking projection comes into contact with the insertion guide surface and is guided toward each locking hole by the inclination of the insertion guide surface. Accordingly, each locking projection is guided to each locking hole. In addition, the wire harness is held in a state in which the three directions are surrounded by the harness holding member, and the straight surface locking hole that is relatively easy to see in the harness housing chamber has a circular shape and is less visible than the straight surface locking hole. By making the locking hole of the inclined surface into a long hole shape, the insertion workability of the locking protrusion of the clip is improved. Furthermore, by making the surface that is harder to see than the locking hole on the straight surface, the insertion force of the locking protrusion of the clip can be easily applied to the locking hole on the inclined surface. Workability will be improved.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0016]

FIG. 4 is a perspective view showing a state in which the clip locking projection is inserted into the locking hole of the under cover, and FIG. 5A is a clip locking projection. FIG. 5B is a cross-sectional view showing a state in which the locking protrusions of the clip are inserted into the locking holes of the under cover.
[0017]
As shown in FIG. 1 to FIG. 4, clips 10 are attached to appropriate positions of the wire harness W of a bundle of a plurality of electric wires. Each clip 10 includes a restraining band portion 11 that restrains the wire harness W in a lump, It has a locking projection 12 connected to the restraining band portion 11. As shown in FIGS. 5 (a) and 5 (b), the locking projection 12 of each clip 10 has a rod portion 12a and a pair of elastic members extending in a direction extending from the tip of the rod portion 12a toward the front. It consists of locking arm portions 12b, 12b, and when each elastic locking arm portion 12b receives an external force in the central direction, it can be elastically deformed in the direction of diameter reduction.
[0018]
The electrical connection box (not shown) is composed of an electrical connection main body having a built-in electric circuit, and a cover 13 that accommodates the electrical connection main body inside. The electrical connection main body is mounted with an electronic component such as a fuse on the upper surface side, and the end of the wire harness W is connected to the lower surface side. The cover 13 is a harness holding member that covers, for example, an upper cover that covers the upper surface side of the electrical connection main body, a side cover that is disposed to cover the side surface of the electrical connection main body, and the bottom surface of the electrical connection main body. The under cover 14 is assembled and fixed to the vehicle body inner plate (both not shown) via the under cover 14.
[0019]
Below the under cover 14, there are provided a bottom wall 15, a side wall 16 erected from the bottom wall 15, and a top wall 17 disposed at the upper end of the side wall 16, and thereby, three directions of the wire harness are provided. A harness housing chamber 18 is formed surrounding the housing. The harness housing chamber 18 is a part of the wiring path of the wire harness W, and the end portion of the wire harness W routed here is guided downward from the under cover 14 into the cover 13.
[0020]
The opposing surface (surface of the side wall 16) disposed at the back with respect to the opening side of the harness housing chamber 18 is a straight surface 16a extending straight and inclined toward the opening side of the harness housing chamber 18 with respect to the straight surface 16a. The straight surface 16a and the inclined surface 16b are formed with locking holes 19 and 20, respectively. A conical insertion guide surface 21 whose depth gradually increases as it approaches the locking holes 19 and 20 is provided around the entire periphery of the locking holes 19 and 20. The locking hole 19 of the straight surface 16a is formed in a circular hole shape, and the locking hole 20 of the inclined surface 16b is formed in a long hole shape extending along the harness routing direction.
[0021]
Next, the operation of holding the wire harness W in the wire harness holding structure will be described. The appropriate position of the wire harness W is restrained by the restraining band portion 11 of each clip 10. Here, the interval between the two clips 10 is set to be the interval between the locking hole 19 of the straight surface 16a and the locking hole 20 of the inclined surface 16b. Next, the wire harness W is inserted into the harness housing chamber 18 of the under cover 14 with the locking projection 12 of each clip 10 attached to the wire harness W being forward. Then, the locking projection 12 of each clip 10 is inserted in alignment with the locking holes 19 and 20.
[0022]
Here, when the locking projection 12 coincides with the position of the locking holes 19, 20, the locking projection 12 is immediately inserted into the locking holes 19, 20. The locking projections 12 inserted into the locking holes 19 and 20 are allowed to be inserted into the locking holes 19 and 20 when the elastic locking arm portions 12b are elastically deformed in the diameter reducing direction, and the insertion is completed. When inserted to the position, the elastic locking arm portion 12b is elastically restored and deformed, whereby the locking projection 12 is locked to the side wall 16 (state shown in FIG. 5B).
[0023]
Further, as shown in FIG. 5A, when the locking projection 12 of each clip 10 is displaced from the position of the locking holes 19, 20, the tip of the locking projection 12 contacts the insertion guide surface 21. Is done. When the locking projection 12 is further inserted from this state, the locking projection 12 is gradually guided toward the locking holes 19 and 20 due to the inclination of the insertion guide surface 21 and finally into the locking holes 19 and 20. Inserted. As described above, the locking projections 12 inserted into the locking holes 19 and 20 are inserted into the locking holes 19 and 20 deeply when the elastic locking arm portions 12b are elastically deformed in the direction of diameter reduction. When it is allowed to be inserted to the insertion completion position, the elastic locking arm portion 12b is elastically restored and deformed, whereby the locking projection 12 is locked to the side wall 16 (state shown in FIG. 5B).
[0024]
As described above, even if the wire harness W and surrounding installation parts, in particular, the under cover 14 of the electrical junction box blocks the field of view of the operator and the locking holes 19 and 20 are difficult to see or are not visible at all, the locking protrusions The inserting operation into the twelve locking holes 19 and 20 can be easily performed.
[0025]
In the said embodiment, the locking holes 19 and 20 are provided in two places of the under cover 14, this one locking hole 19 is made into a circular hole shape, and the other locking holes 20 are extended along a harness wiring direction. Since each of the long holes is formed, the wire harness W is restrained by the two clips 10, and the two clips 10 are inserted into the two locking holes 19, 20. Even when the length between 10 is slightly different from the length between the two locking holes 19, 20, it is possible to insert each locking projection 12 into each locking hole 19, 20. There is no need to mount the dimensions exactly.
[0026]
In the above-described embodiment, the wire harness W is accommodated in the under cover 14, the harness accommodating chamber 18 that surrounds the three directions of the accommodated wire harness W is provided, and disposed behind the opening-side surface of the harness accommodating chamber 18. Since the locking holes 19 and 20 are formed in the surfaces 16a and 16b of the side wall 16 to be formed, the wire harness W is held in a state where the three directions are surrounded by the under cover 14, and thus the wiring harness that has been routed is completed. The situation where W is interfered with by other parts can be prevented as much as possible.
[0027]
And the locking holes 19 and 20 are formed in the inner surfaces 16a and 16b of the harness accommodating chamber 18 surrounding the three directions of the wire harness W, and the locking holes 19 and 20 are almost not at the time of inserting the locking projections 12. Although the insertion operation in a state where it cannot be seen is unavoidable, the insertion operation of the locking projection 12 can be easily performed by the guide action of the locking projection 12 by the insertion guide surface 21. In addition, since the inclined surface 16b is more difficult to see than the locking hole 19 of the straight surface 16a of the side wall 16, the insertion force of the locking projection 12 of the clip 10 into the locking hole 20 of the inclined surface 16b is increased. As a result, the wire harness W can be easily assembled.
[0028]
As described above, the wire harness W is held in a state in which the wire harness W is housed in the harness housing chamber 18 that surrounds the three directions of the wire harness W, and the insertion operation of the locking protrusion 12 can be easily performed. In addition, as described above, in the electrical connection box, the connection portion of the wire harness W is disposed on the lower side of the electrical connection main body portion accommodated in the cover 13, and the under cover 14 is disposed below the cover 13. There is a desire to route the wire harness W around the wire and to protect the wire harness W from the outside, and the above embodiment can easily insert the locking projection 12 while satisfying such a demand. Is.
[0029]
In the above-described embodiment, the opposite surface to the opening side of the harness housing chamber 18, that is, the side wall 16 has a straight surface 16a extending straight and the opening side of the harness housing chamber 18 with respect to the straight surface 16a. The circular locking hole 19 is formed in the straight surface 16a, and the long locking hole 20 is formed in the inclined surface 16b. That is, the locking hole 19 of the straight surface 16a that is relatively easy to see has a circular hole shape, and the locking hole 20 of the inclined surface 16b that is hard to see than the locking hole 19 of the straight surface 16a has a long hole shape. The wire harness W is held in a state in which the wire harness W is housed in the harness housing chamber 18 that surrounds the three directions, and the insertion workability of the locking protrusion 12 is improved.
[0030]
In particular, the locking hole 20 of the inclined surface 16b of the side wall 16 is difficult to see, or the length between the locking hole 20 of the inclined surface 16b and the locking hole 19 adjacent thereto is between the two clips 10. However, it is difficult to adjust the size of each of the clips 10 because the guide action of the locking projection 12 by the insertion guide surface 21 and the one locking hole 20 is a long hole shape and it is not necessary to strictly set the dimension between the clips 10. 12 insertion operations can be easily performed.
[0031]
In addition, according to the said embodiment, although the case where the wire harness holding structure was applied to what hold | maintains the wire harness W in the vicinity of the electrical junction box of a motor vehicle was demonstrated, the wire harness routed other than a motor vehicle is used. Needless to say, the present invention can be applied to the case of holding. Moreover, according to the said embodiment, although the locking hole was provided in two places of an undercover, you may provide a locking hole in three or more places. In this case, one locking hole is formed as a circular hole, and the other two or more locking holes are formed as long holes.
[0032]
【The invention's effect】
As described above, according to the first aspect of the present invention, the locking hole at one location of the harness holding member is formed in a circular hole shape, and the other locking holes are formed in a long hole shape. When restraining with two or more clips and inserting the locking projections of each clip into two or more locking holes, the length between the clips is slightly different from the length between the locking holes. Even in this case, it is possible to easily perform the operation of inserting each locking projection into each locking hole. Therefore, it is not necessary to set the dimension between the clips strictly. Further, since there is provided the predetermined insertion guide surface around each locking hole of the harness holding member, when the locking projection is inserted into a position shifted from the locking holes, each locking projection is inserted guide contact with the surface, since each locking projection from being guided toward each locking hole at an inclination of the insertion guide surface is directed to the respective locking holes, installation parts and around the wire harness the view of the operator hardly obstruct locking hole is visible, or even when the completely invisible, it is possible to perform the work of inserting into each engaging hole of the engaging projections easily.
[0034]
Moreover , since a wire harness is hold | maintained in the state where three directions were surrounded by the harness holding member, the situation where a wire harness interferes with other components etc. can be prevented as much as possible. And each latching hole is formed in the surface of the harness accommodating chamber surrounding three directions of a wire harness, and the insertion operation in the state which can hardly see each latching hole at the time of the insertion operation of each latching projection is forced. However, the insertion operation of each locking projection can be easily performed by the guide action of each locking projection by the insertion guide surface. Thereby, there exists what hold | maintains a wire harness in the state which accommodated the wire harness in the harness storage chamber surrounding three directions of a wire harness, and the insertion operation | work of each latching protrusion can be performed very easily.
[0035]
In particular, by making the locking hole of the straight surface relatively easy to see in the harness housing chamber into a circular hole shape and making the locking hole of the inclined surface difficult to see than the locking hole of the straight surface into a long hole shape, It is what holds a wire harness in the state which accommodated the wire harness in the harness storage chamber surrounding 3 directions, and can improve the insertion workability | operativity of the latching protrusion of a clip further. In addition, by making the surface that is harder to see than the locking hole on the straight surface, it becomes easier to apply the insertion force of the locking protrusion of the clip to the locking hole on the inclined surface. Workability can be further improved.
