Description

【０００１】
【発明の属する技術分野】
この発明は、自動車の車体や電気機器等のパネルの開口部に電線を通すためのグロメットに関し、代表的な例としては、自動車の車体パネルの貫通穴に、ワイヤハーネスを内部に挿通した状態で装着するグロメットがあり、特に、車体パネルに対してグロメットが正規装着状態で確実に装着されているか否かを一目で確認できるようにしたグロメットに関するものである。
【０００２】
【従来の技術】
従来、自動車のエンジンルーム側の室外と室内側との隔壁を構成する車体パネル等を通してワイヤハーネスを配線する場合、車体パネルに形成された開口部にグロメットを介してワイヤハーネスを貫通させている。この種のグロメット１００としては、図６に示すように、ゴムあるいはエラストマーから成形されるアウター部材１０１とパネル開口部へ挿入される樹脂製のインナー部材１０２とから成る。アウター部材１０１は、ワイヤハーネスの外周に密着する小径の筒部１０３と、この小径の筒部１０３の一端側に形成されインナー部材１０２を保持する台座部１０４と、この台座部１０４の内周側に形成されパネルに押し付けて水をシールするシール部１０５と、電線間から水の浸入を防ぐための遮水剤注入部１０６とから構成されている。また、インナー部材１０２は、筒部１０７と、筒部１０７の外周部に設けた複数の係止用ロック１０８と、筒部１０７の後端側に形成されたフランジ１０９（図６参照）とから構成されている。図７及び図８は、パネル１０の開口部１０Ａに図６に示すグロメット１００を装着した状態を示す。
【０００３】
図６ないし図８に示す従来のグロメット１００では、例えば係止用ロック１０８を４ヶ設けた場合、図８に示すようなボックス型のパネル１０に装着したときに下側の２ヶの係止用ロック１０８が目視できず、ロックされているかどうか確認することができない。また、パネル１０の板厚が厚い場合、複数の係止用ロック１０８が同時にロックすることは稀であり、一部の非ロック個所を見落すおそれがあった。
【０００４】
そこで、係止用ロックがグロメットをパネルに装着したときに確実にロックしているかどうかを容易に確認できるようにしたもの（例えば、特許文献１参照）も開発された。これは、ワイヤハーネスの外周に密着する小径筒部と、該小径筒部の一端より拡径すると共に外周面に車体パネルの貫通穴に係合する係合溝を有する拡径部とを備え、上記係合溝の側壁端縁より貫通穴周縁の車体パネルに圧接するシールリップを突設してなるグロメットにおいて、上記シールリップの外面に、グロメットの色とは異なる色からなる装着確認用目印を設け、シールリップが径方向の外向きに変形して車体パネルに圧接すると上記装着確認用目印が外観できる構成としたものである。
【０００５】
【特許文献１】
特開平９−６３３８６号公報（第３−４頁、図１）
【０００６】
【発明が解決しようとする課題】
特許文献１に記載のものでも、図８のようなボックス型のパネル１０に装着した場合には、下側のシールグリップは目視できず、ロック状態を確認することはできなかった。
【０００７】
そこで、この発明は、グロメットのパネル装着が確実になされているかどうかの確認が一目でわかるようにしたグロメットを提供することを目的とする。
【０００８】
【課題を解決するための手段】
上述の目的を達成するため、この発明は、外周部に車体や電気機器等のパネルの開口部の一方の片面に係止される複数の係止用ロックを設けたインナー部材と、このインナー部材の一端側の外周部を取囲むようにインナー部材に取付けられ前記パネルの開口部の他方の片面に装着されるシール部を設けたアウター部材と、このアウター部材に設けられた電線を通すための筒部とを備えたグロメットにおいて、前記インナー部材の外周部に係止用ロックとは別に目印用ロックを設け、このインナー部材をパネルの開口部に挿入してパネルの一方の片面に係止させた後さらにインナー部材を挿入したときに目印用ロックをパネルに係止するように構成し、この目印用ロックを視認可能なインナー部材の外周部個所に設け、前記インナー部材をパネルの開口部に挿入してパネルの一方の片面に係止させた後さらにインナー部材を挿入したときに目印用ロックをパネルに係止するように構成し、前記係止用ロックがパネルに係止する直前のインナー部材の前端面からパネルまでの高さをｈ １ 、前記目印用ロックがパネルに係止する直前のインナー部材の前端面からパネルまでの高さをｈ ２ とすると、ｈ １ ＜ｈ ２ の関係にあるものである。
【０００９】
【発明の実施の形態】
以下に、この発明の好適な実施例を図面を参照にして説明する。
【００１０】
図１に示す実施例において、グロメット１はインナー部材２とアウター部材３とから構成してあり、インナー部材２の筒部４の外周部４Ａに車体や電気機器等のパネル１０の開口部１０Ａの一方の片面に係止される複数の係止用ロック５を設けてある。さらに、インナー部材２の外周部４Ａには係止用ロック５とは別に目印用ロック６を設けてある。この目印用ロック６は視認可能な個所に設けてある。図示する実施例では、２つの係止用ロック５の中間部分に設けてある。
【００１１】
上述したインナー部材２と組合されるアウター部材３はインナー部材２の一端側の外周部を取囲むように設けたシール部７を、インナー部材２を保持する台座部８と、この台座部８の外側に形成された遮水剤注入部９と、電線の外周に密着する小径の筒部１１とからなるものである。また、アウター部材３はゴムあるいはエラストマーから成形される。このアウター部材３の構成は従来例として説明したものと同様である。
【００１２】
図２は、パネル１０にグロメット１を装着した状態を示し、目印用ロック６がパネル１０の一方の片面に係止された状態を示す。インナー部材２をパネル１０の開口部１０Ａに挿入してゆくと、目印用ロック６が筒部４側へ押し付けられ、この目印用ロック６が開口部１０Ａから抜け出た状態ではそのばね力により筒部４から遠ざかる方向へ戻る。この目印用ロック６が戻った状態においてその先端はパネル１０の一方の片面に係止する。また、シール部７はパネル１０の他方の片面に水密性を保って密接する。アウター部材３の台座部８は、インナー部材２のフランジ４Ｂに装着されている。
【００１３】
前記インナー部材２は射出成形などにより成形された樹脂製のものが好適に使用できる。前記係止用ロック５と目印用ロック６とは、インナー部材２の筒部４の前端面側に一端側が固着され、自由端側はインナー部材２から浮かされ、この自由端がインナー部材２側へ押された後に元に復帰するばね性を有する板ばね状部材から成っている。このような板ばね状の樹脂製のロック５，６は、インナー部材２を合成樹脂材料から成形するときに、これらロック５，６も同時成形される。また、板ばね状部材から形成した目印用ロック６は、係止用ロック５の幅よりも大きく（例えば２倍程度）形成しておくことにより、目視し易いものとなる。
【００１４】
図３及び図４は、パネル１０の開口部１０Ａにインナー部材２を挿入して係止用ロック５及び目印用ロック６が共に係止する寸前の状態を示す断面であり、係止用ロック５がパネル１０に係止する直前のインナー部材２の前端面からパネル１０までの高さをｈ１、目印用ロック６がパネル１０に係止する直前のインナー部材２の前端面からパネル１０までの高さをｈ２とすると、ｈ１＜ｈ２の関係にある。このようにｈ１＜ｈ２の関係にあることにより、係止用ロック５がパネル１０に係止した後に目印用ロック６がパネル１０に係止するようになる。これにより、係止用ロック５の掛かり状態を目印用ロック６を目視することにより確認することができる。なお、係止用ロック５の自由端にはパネル１０の開口部１０Ａの角部に係止するための係止段部５Ａが形成してある。
【００１５】
図５に示す他の実施例では、目印用ロック６にインナー部材２の外周部４Ａとは異なる着色を施してある。これにより目印用ロック６を目視し易くなる。
【００１６】
上述した実施例では、目印用ロック６は一個所にのみ設けたが、二個所以上目印用ロック６を設けることも可能である。また、上述した実施例におけるインナー部材２は、左右ほぼ同じ大きさに二分割された２部材から形成してあり、比較的大きな開口部１０Ａに装着するようなグロメット１の場合には、このようにインナー部材２を二分割するのが製作上等からも好ましい。
【００１７】
【発明の効果】
以上説明したように、この発明によれば、外周部に車体や電気機器等のパネルの開口部の一方の片面に係止される複数の係止用ロックを設けたインナー部材と、このインナー部材の一端側の外周部を取囲むようにインナー部材に取付けられ前記パネルの開口部の他方の片面に装着されるシール部を設けたアウター部材と、このアウター部材に設けられた電線を通すための筒部とを備えたグロメットにおいて、前記インナー部材の外周部に係止用ロックとは別に目印用ロックを設け、このインナー部材をパネルの開口部に挿入してパネルの一方の片面に係止させた後さらにインナー部材を挿入したときに目印用ロックをパネルに係止するように構成し、この目印用ロックを視認可能なインナー部材の外周部個所に設けたので、目印用ロックの係止状態を確認することにより、係止用ロックの係止状態を正確に確認することができる。また、目印用ロックの係止を係止用ロックの係止がなされた直後に行わせるために、係止用ロックがパネルに係止する直前のインナー部材の前端面からパネルまでの高さをｈ１、目印用ロックがパネルに係止する直前のインナー部材の前端面からパネルまでの高さをｈ２とすると、ｈ１＜ｈ２の関係とすることにより、容易に実現することができる。また、目印用ロックに着色を施すことにより或いは目印用ロックを係止用ロックよりも大きく形成することにより目視して確認することがきわめて容易となる。

It consists of a water-blocking agent injection part 9 formed on the outside and a small-diameter cylindrical part 11 that is in close contact with the outer periphery of the electric wire. The outer member 3 is formed from rubber or elastomer. The configuration of the outer member 3 is the same as that described as the conventional example.
[0012]
FIG. 2 shows a state where the grommet 1 is attached to the panel 10, and shows a state where the mark lock 6 is locked to one side of the panel 10. When the inner member 2 is inserted into the opening 10A of the panel 10, the mark lock 6 is pressed toward the cylinder part 4, and when the mark lock 6 is pulled out from the opening 10A, the cylinder part is caused by its spring force. Return in a direction away from 4. In a state where the mark lock 6 is returned, the tip end is engaged with one side of the panel 10. Further, the seal portion 7 is in close contact with the other surface of the panel 10 while maintaining water tightness. The pedestal portion 8 of the outer member 3 is attached to the flange 4 </ b> B of the inner member 2.
[0013]
The inner member 2 is preferably made of resin molded by injection molding or the like. One end of each of the locking lock 5 and the mark lock 6 is fixed to the front end face side of the cylindrical portion 4 of the inner member 2, the free end is floated from the inner member 2, and the free end is directed to the inner member 2 side. It consists of a leaf spring-like member having a spring property that returns to its original state after being pushed. Such plate spring-like resin locks 5 and 6 are simultaneously formed when the inner member 2 is formed from a synthetic resin material. Further, the mark lock 6 formed from a leaf spring-like member is formed to be larger than the width of the locking lock 5 (for example, about twice), thereby making it easy to visually check.
[0014]
3 and 4 are cross-sectional views showing a state immediately before the locking member 5 and the mark lock 6 are locked together by inserting the inner member 2 into the opening 10A of the panel 10. H 1 is the height from the front end surface of the inner member 2 immediately before locking to the panel 10 to the panel 10, and the height from the front end surface of the inner member 2 immediately before the mark lock 6 is locked to the panel 10 to the panel 10. When the height is h 2 , the relationship is h 1 <h 2 . Thus, by having a relationship of h 1 <h 2 , the mark lock 6 is locked to the panel 10 after the locking lock 5 is locked to the panel 10. Thereby, the hooking state of the locking lock 5 can be confirmed by visually observing the mark lock 6. A locking step 5A for locking to the corner of the opening 10A of the panel 10 is formed at the free end of the locking lock 5.
[0015]
In another embodiment shown in FIG. 5, the mark lock 6 is colored differently from the outer peripheral portion 4 </ b> A of the inner member 2. This makes it easier to visually check the mark lock 6.
[0016]
In the embodiment described above, the mark lock 6 is provided only at one place, but it is possible to provide the mark lock 6 at two or more places. Further, the inner member 2 in the above-described embodiment is formed of two members divided into two substantially the same size on the left and right sides. In the case of the grommet 1 to be mounted in the relatively large opening 10A, this is the case. The inner member 2 is preferably divided into two parts from the viewpoint of production.
[0017]
