Description

本発明は、自動車に配索されるワイヤハーネスに取り付けられるグロメットに関し、詳しくは、車体パネルに設けた貫通孔に挿通係止して取り付けられ、該グロメットを貫通するワイヤハーネスが貫通直後に2方向に分岐される場合に好適に用いられるものである。   The present invention relates to a grommet attached to a wire harness routed in an automobile. Specifically, the grommet is inserted and locked in a through hole provided in a vehicle body panel, and the wire harness penetrating the grommet is in two directions immediately after penetrating. It is suitably used when branching into two.
自動車に配索されるワイヤハーネスに取り付けられるグロメットは、車室と室外(エンジンルーム)とを仕切る車体パネルに設けられた貫通孔に取り付けて室内側への浸水を防止するものである。図6に示すグロメット1は、この種のグロメットの一例を示すものであり、ワイヤハーネスWの外周に密着させて挿通する室外側電線挿通部2と室内側電線挿通部3を備え、この室外側電線挿通部2と室内側電線挿通部3を、貫通孔の周縁に嵌合係止する環状溝4aを設けた拡径部4を介して連続させている。   A grommet attached to a wire harness routed in an automobile is attached to a through-hole provided in a vehicle body panel that separates the vehicle compartment from the outside (engine room) to prevent water from entering the indoor side. A grommet 1 shown in FIG. 6 is an example of this type of grommet, and includes an outdoor electric wire insertion portion 2 and an indoor electric wire insertion portion 3 that are inserted in close contact with the outer periphery of the wire harness W. The electric wire insertion part 2 and the indoor side electric wire insertion part 3 are made continuous via the enlarged diameter part 4 provided with an annular groove 4a fitted and locked to the periphery of the through hole.
前記グロメット1を介してエンジンルーム側から挿通されたワイヤハーネスを室内側で分岐するときは、図6に示すように、グロメット1の外部で、かつ、室内側電線挿通部3の開口端部3aに近接した箇所でワイヤハーネスWを分岐したのち、分岐線w1を配索方向へと曲げる。しかしながら、グロメット1が取り付けられた貫通孔に近接して空調装置等の外部干渉材(図示せず)が配置されていると、分岐線w1を曲げるスペースSが十分に存在せず、分岐線w1を曲げられない、あるいは、曲げた分岐線w1が他の部品と干渉してしまうことがある。   When the wire harness inserted from the engine room side through the grommet 1 is branched on the indoor side, as shown in FIG. 6, the opening end 3 a of the indoor side electric wire insertion part 3 is provided outside the grommet 1. After branching the wire harness W at a location close to, the branch line w1 is bent in the routing direction. However, if an external interference member (not shown) such as an air conditioner is disposed in the vicinity of the through hole to which the grommet 1 is attached, there is not enough space S for bending the branch line w1, and the branch line w1. May not be bent, or the bent branch line w1 may interfere with other parts.
特に、昨今の自動車は小型化が進む一方で、高機能化も進み、車載装備が増大しているため、特に室内側では限られたスペースに多くのワイヤハーネスを配索する必要がある。しかしながら、前記グロメット1のような従来のグロメットでは、ワイヤハーネスの分岐位置、通線レイアウト等の制約が多く、車両内スペースの有効活用およびワイヤハーネス配索スペースの省スペース化への要請に応じれなくなりつつある。   In particular, recent automobiles have been reduced in size, advanced in functionality, and equipped with in-vehicle equipment. Therefore, it is necessary to route a large number of wire harnesses in a limited space, particularly on the indoor side. However, the conventional grommet such as the grommet 1 has many restrictions such as the branch position of the wire harness and the wiring layout, and responds to requests for effective utilization of the space in the vehicle and space saving of the wiring harness wiring space. It is disappearing.
この問題に関し、特開平8−212858号(特許文献1)では、図7(A)(B)に示すように、貫通孔Hの周縁に取り付けられる車体係止部6より、室外側に電線挿通部7を延出形成し、室内側には引張片8を延出形成し、該引張片8の一部に電線挿通可能な切欠9を設けたグロメット5が提案されている。該グロメット5は、引張片8を室内側へと引っ張り、車体係止部6を変形させて貫通孔Hの周縁に嵌合係止させるときに、電線wも同時に室内側に引き込んでしまうことがないように、該引張片8を電線wに非接触な大径筒状に形成している。   With respect to this problem, in Japanese Patent Application Laid-Open No. 8-212858 (Patent Document 1), as shown in FIGS. 7A and 7B, an electric wire is inserted into the outdoor side from the vehicle body locking portion 6 attached to the periphery of the through hole H. A grommet 5 is proposed in which a portion 7 is extended, a tensile piece 8 is extended on the indoor side, and a notch 9 into which a wire can be inserted is provided in a part of the tensile piece 8. When the grommet 5 pulls the tension piece 8 toward the indoor side, deforms the vehicle body locking portion 6 and engages and locks it with the periphery of the through hole H, the electric wire w may be simultaneously pulled into the indoor side. The tension piece 8 is formed in a large-diameter cylindrical shape that is not in contact with the electric wire w so as not to be present.
前記グロメット5は、室内側に取り付けられる前記引張片8が大径筒状であるため、該引張片8内部で電線wを曲げることができ、かつ、図7(B)に示すように、該引張片8に形成された前記切欠9に電線wを挿入することにより、電線wを曲げた状態で安定的に保持することができる。これにより、電線wをより手前で曲げることができるため、室内側のスペースが限られていても無理なく曲げることができ、他の部品との干渉も防止できる。   In the grommet 5, since the tensile piece 8 attached to the indoor side has a large-diameter cylindrical shape, the electric wire w can be bent inside the tensile piece 8, and as shown in FIG. By inserting the electric wire w into the notch 9 formed in the tension piece 8, the electric wire w can be stably held in a bent state. Thereby, since the electric wire w can be bent more near, even if the space on the indoor side is limited, it can be bent without difficulty, and interference with other parts can also be prevented.
しかしながら、前記グロメット5は、前記引張片8が大径筒状であり、室内側端部8aが開口しているうえ、挿通される電線wの外周にも密着しない。従って、室外側のノイズが室内に漏れやすく、防音性、静音性に問題がある。   However, in the grommet 5, the tension piece 8 has a large-diameter cylindrical shape, the indoor side end 8a is open, and the grommet 5 does not adhere to the outer periphery of the inserted wire w. Therefore, outdoor noise tends to leak into the room, and there is a problem in soundproofing and quietness.

前記一対の巻付片は、中央部は傾斜部とし、該傾斜部の端縁を所要寸法ラップさせて前記開口を閉鎖し、かつ、該中央部の傾斜部の両側部から円弧部を突設して連続させ、該円弧部の端縁を所要寸法ラップして、前記拡径筒部の軸線方向と直交方向の両側に延在する一対の分岐線用小径筒部を設け、
前記拡径筒部の内部で前記幹線より直交方向に分岐されるワイヤハーネスの一対の分岐線を、前記一対の巻付片がラップされて形成される前記分岐線用小径筒部に挿通させて車室側に引き出す構成としていることを特徴とするグロメットを提供している。
In order to solve the above-mentioned problem, the present invention is a grommet that is penetrated and locked in a state where it is sheathed on a wire harness in a through hole formed in a vehicle body panel that partitions an engine room and a vehicle compartment of an automobile,
A small-diameter cylindrical portion for one main line through which the main line of the wire harness routed on the engine room side is inserted;
A diameter-enlarging cylinder part provided with a vehicle body locking part that is continuous with the small-diameter cylinder part for the main line and is formed by an annular groove that is locked to the periphery of the through hole;
A pair of winding pieces connected to the periphery of the opening on the large-diameter end side of the enlarged-diameter cylindrical portion ;
The pair of winding pieces has an inclined portion at the center, the edge of the inclined portion is wrapped with a required dimension to close the opening, and arc portions project from both sides of the inclined portion of the center portion. And a pair of small-diameter cylindrical portions for branch lines extending to both sides in the direction orthogonal to the axial direction of the diameter-enlarging cylindrical portion by wrapping the edge of the arc portion with a required dimension ,
A pair of branch lines of a wire harness branched in an orthogonal direction from the trunk line inside the diameter-expanded cylinder part are inserted into the small diameter cylinder part for the branch line formed by wrapping the pair of winding pieces. A grommet characterized by being pulled out to the passenger compartment is provided.
前記構成のグロメットを用いると、従来であればグロメット外部の室内側空間を利用して分岐せざるを得なかったワイヤハーネスを、貫通孔寄りの、グロメットの前記拡径筒部内で分岐できる。また、分岐された一対の分岐線をそれぞれ前記分岐線用小径筒部に挿通させることにより、分岐線の曲げられた状態を安定的に保持することができる。従って、ワイヤハーネスの分岐配索スペースの無駄を省くことができ、グロメット周辺の室内側スペースが狭い場合でも、室外側から引き込まれたワイヤハーネスを無理なく分岐配線でき、かつ、分岐線が室内側の車載部品と干渉することも防止できる。   When the grommet having the above-described configuration is used, a wire harness that had to be branched using an indoor space outside the grommet in the past can be branched in the enlarged diameter cylindrical portion of the grommet near the through hole. Moreover, the bent state of the branch line can be stably maintained by inserting the pair of branched branches into the small-diameter cylindrical portion for the branch line. Therefore, it is possible to eliminate the waste of the wiring and wiring space for the wire harness, and even when the indoor space around the grommet is small, the wiring harness drawn from the outdoor side can be branched without difficulty, and the branch line is connected to the indoor side. Interference with other on-vehicle components can also be prevented.
また、前記巻付片をラップすることにより、拡径筒部の大径側開口を閉鎖し、かつ、前記分岐線の外周を前記分岐線用小径筒部で覆うことができるため、エンジンルーム側のノイズの室内側への音漏れを遮断でき、室内側の静音性、快適性を確保できる。   Further, by wrapping the winding piece, it is possible to close the large-diameter side opening of the enlarged-diameter cylindrical portion and to cover the outer periphery of the branch line with the small-diameter cylindrical portion for the branch line. The sound leakage of the noise to the indoor side can be blocked, and the quietness and comfort of the indoor side can be secured.
前記一対の巻付片の端縁の中央部は所要寸法ラップして前記開口を閉鎖し、かつ、該中央部を挟む両側部は円弧状に連続されると共に端縁が所要寸法ラップして前記分岐線用小径筒部を形成している。これにより、分岐線用小径筒部を形成する前記巻付片は、分岐線の外周の湾曲に沿ってラップされ、分岐線外周に密着しやすくなるため、防音性をより高めることができる。 The center part of the edge of the pair of winding pieces is wrapped with a required dimension to close the opening, and both side parts sandwiching the center part are continuously arcuate and the edge is wrapped with a required dimension. that form a small-diameter cylindrical portion for the branch line. Thereby, since the said winding piece which forms the small diameter cylinder part for branch lines is wrapped along the curve of the outer periphery of a branch line, and becomes easy to closely_contact | adhere to a branch line outer periphery, soundproofing can be improved more.
前記一対の巻付片の互いにラップされる部分には、一方の巻付片に係止部、他方の巻付片に被係止部を設け、これらを係止する構成とすることが好ましい。これにより、巻付片をラップしたときに、外側巻付片が内側巻付片より浮き上がることを規制できるため、内外巻付片の隙間から室内側に音漏れすることを防止でき、高い防音性を備えることができる。   It is preferable that a portion of the pair of winding pieces that are wrapped with each other is provided with a locking portion on one winding piece and a locked portion on the other winding piece, and these are locked. As a result, when the winding piece is wrapped, the outer winding piece can be prevented from floating above the inner winding piece, so that sound can be prevented from leaking into the room from the gap between the inner and outer winding pieces, and high soundproofing Can be provided.
前記係止部は舌状係止片とし、前記被係止部は舌状係止片を挿入するスリットとしてもよい。   The locking portion may be a tongue-shaped locking piece, and the locked portion may be a slit for inserting the tongue-shaped locking piece.
上述したように、本発明によれば、貫通孔を挿通したワイヤハーネスを、室内側で、より貫通孔寄りの位置で分岐できるうえ、分岐された一対の分岐線を曲げた状態で安定的に保持できる。従って、限られた狭い車室スペースにおいてもワイヤハーネスを無理なく分岐配線できるとともに、該分岐線が他の車載部品と干渉することも防止できる。   As described above, according to the present invention, the wire harness inserted through the through hole can be branched at a position closer to the through hole on the indoor side, and the pair of branched branch lines can be stably bent. Can hold. Therefore, it is possible to branch the wiring harness without difficulty even in a limited space of the passenger compartment, and to prevent the branch line from interfering with other in-vehicle components.
また、巻付片をラップすることにより、グロメットの室内側開口を閉鎖でき、かつ、分岐線の外周を分岐線用小径筒部で覆うことができるため、エンジンルーム側から室内側へのノイズ漏れを防止でき、車室の静音性を確保できる。   In addition, by wrapping the wrapping piece, the indoor opening of the grommet can be closed and the outer periphery of the branch line can be covered with a small-diameter cylindrical portion for the branch line, so noise leakage from the engine room side to the indoor side Can be prevented, and the quietness of the passenger compartment can be secured.
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は、本発明の第一実施形態に係るグロメット10を示し、該グロメット10は、自動車のエンジンルームX側と車室Y側とを仕切る車体パネルPに設けた貫通孔Hに通すワイヤハーネス30に外装される。
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 3 show a grommet 10 according to a first embodiment of the present invention, and the grommet 10 is formed in a through-hole H provided in a vehicle body panel P that partitions an engine room X side and a vehicle compartment Y side of an automobile. It is armored by the wire harness 30 to pass.
前記グロメット10は、図1に示すように、エンジンルームX側に配索されるワイヤハーネス30の幹線31の外周を密着させて挿通する1つの幹線用小径筒部12と、拡径筒部13と、開閉可能な一対の巻付片16、17を樹脂で連続一体に成形してなる。   As shown in FIG. 1, the grommet 10 has one main-diameter small-diameter cylindrical portion 12 that is inserted in close contact with the outer periphery of the main-line 31 of the wire harness 30 that is routed on the engine room X side, and an enlarged-diameter cylindrical portion 13. And a pair of wrapping pieces 16 and 17 that can be opened and closed are integrally formed of resin.
前記拡径筒部13は、前記幹線用小径筒部12の一端に連続して形成されると共に、他端側に、前記貫通孔Hの周縁に係止される大径筒状の車体係止部14を形成している。該車体係止部14の外周には、貫通孔Hの周縁に嵌合する環状溝15を凹設している。   The large diameter cylindrical portion 13 is formed continuously with one end of the main diameter small diameter cylindrical portion 12 and is secured to the other end side with a large-diameter cylindrical vehicle body locked to the periphery of the through hole H. Part 14 is formed. An annular groove 15 that is fitted to the periphery of the through hole H is provided in the outer periphery of the vehicle body locking portion 14.
前記一対の巻付片16、17は、前記拡径筒部13の先端の大径側開口13aの周縁13bに連続して突設されている。該巻付片16、17は、図1および図2(A)(B)(C)に示すように、中央部の傾斜部16c、17cと、該傾斜部16c、17cより上方に突設された円弧部16a、17aと、該傾斜部16c、17cより下方に突設された円弧部16b、17bと、閉鎖時に互いにラップする所要幅の閉じ代部16d、17dよりなる。前記円弧部16a、17a、16b、17bは、前記拡径筒部13の軸線方向に対して直交方向の両側に延在するように突設されている。また、前記閉じ代部16d、17dは巻付片16、17それぞれの巻付け端部に形成され、前記傾斜部16c、17cと巻付け方向に連続する部分は平坦部16e、17eとし、前記円弧部16a、17a、16b、17bと巻付け方向に連続する部分は円弧状としている。   The pair of winding pieces 16, 17 are provided so as to continuously project from the peripheral edge 13 b of the large-diameter side opening 13 a at the tip of the enlarged diameter cylindrical portion 13. As shown in FIGS. 1 and 2A, 2B, and 2C, the winding pieces 16 and 17 project from the central inclined portions 16c and 17c, and project upward from the inclined portions 16c and 17c. Arc portions 16a and 17a, arc portions 16b and 17b projecting downward from the inclined portions 16c and 17c, and closing margin portions 16d and 17d having a required width that wrap around each other when closed. The arc portions 16 a, 17 a, 16 b, and 17 b are provided so as to extend on both sides in the direction orthogonal to the axial direction of the diameter-expanded cylindrical portion 13. The closing margins 16d and 17d are formed at the winding ends of the winding pieces 16 and 17, respectively, and the portions that are continuous with the inclined portions 16c and 17c in the winding direction are flat portions 16e and 17e. Portions that are continuous with the portions 16a, 17a, 16b, and 17b in the winding direction are arcuate.
前記構成のグロメット10を外装してワイヤハーネス30を前記貫通孔Hに挿通する作業は、まず、図2(A)に示すように前記巻付片16、17を開いた状態で、ワイヤハーネス30の幹線31をグロメット10の前記幹線用小径筒部12に挿通し、該幹線31をグロメット10の前記拡径部13の内部で上下方向に分岐する。   The operation of covering the grommet 10 having the above-described configuration and inserting the wire harness 30 through the through hole H is performed by first opening the winding pieces 16 and 17 and opening the wire harness 30 as shown in FIG. The trunk line 31 is inserted into the small diameter cylindrical portion 12 for the trunk line of the grommet 10, and the trunk line 31 is branched in the vertical direction inside the enlarged diameter portion 13 of the grommet 10.
次に、図2(B)(C)に示すように、巻付片16、17で前記分岐線31、32をくるむように、該巻付片16、17を閉鎖する。このとき、閉鎖された巻付片16、17の円弧部16a、17aにより上側の分岐線用小径筒部Aが形成され、円弧部16b、17bにより下側の分岐線用小径筒部Bが形成され、これら分岐線用小径筒部A、Bが前記分岐線32、33の外周にそれぞれ密着するように、前記閉じ代部16d、17dを所要寸法重ねてラップ部Dを形成する。   Next, as shown in FIGS. 2B and 2C, the winding pieces 16, 17 are closed so that the branch lines 31, 32 are wrapped around the winding pieces 16, 17. At this time, the upper branch line small-diameter tube portion A is formed by the arc portions 16a and 17a of the closed winding pieces 16 and 17, and the lower branch line small-diameter tube portion B is formed by the arc portions 16b and 17b. Then, the closing margins 16d and 17d are overlapped with each other to form a wrap portion D so that the small diameter cylindrical portions A and B for branch lines are in close contact with the outer circumferences of the branch lines 32 and 33, respectively.
次いで、幹線31と前記幹線用小径筒部12、分岐線32と前記分岐線用小径筒部A、分岐線33と分岐線用小径筒部Bに、それぞれ粘着テープTを巻きつけて端部をシールする。
最後に、車体パネルPの貫通孔Hに車室Y側からエンジンルームX側へとワイヤハーネス30を挿通し、グロメット10をエンジンルームX側から引っ張って、図3に示すように、前記車体係止部14の環状溝15を貫通孔Hの周縁に嵌合させて該グロメット10を貫通孔Hに係止する。
Next, the adhesive tape T is wound around the trunk line 31 and the small-diameter cylinder part 12 for the trunk line, the branch line 32 and the small-diameter cylinder part A for the branch line, and the branch line 33 and the small-diameter cylinder part B for the branch line, respectively. Seal.
Finally, the wire harness 30 is inserted into the through hole H of the vehicle body panel P from the vehicle compartment Y side to the engine room X side, and the grommet 10 is pulled from the engine room X side. The annular groove 15 of the stop portion 14 is fitted to the periphery of the through hole H, and the grommet 10 is locked to the through hole H.
このように前記グロメット10を用いると、図3に示すように、貫通孔Hに挿通されたワイヤハーネス30をグロメット10の拡径筒部13内で分岐することができ、分岐された一対の分岐線32、33をグロメット10から直接的にそれぞれの配索方向に導出することができる。従って、グロメット10外の車室Y側スペースを用いることなく、より貫通孔H寄りの位置でワイヤハーネス30を分岐できるため、貫通孔H周辺の車室Y側スペースが狭くてもワイヤハーネス30を無理なく分岐できる。また、分岐線用小径筒部A、Bが分岐線32、33それぞれを曲げた状態で保持するため、分岐線32、33と室内側車載部品との干渉も防止できる。   When the grommet 10 is used in this way, as shown in FIG. 3, the wire harness 30 inserted through the through hole H can be branched in the enlarged diameter cylindrical portion 13 of the grommet 10, and a pair of branched branches The lines 32 and 33 can be directly derived from the grommet 10 in the respective wiring directions. Therefore, since the wire harness 30 can be branched at a position closer to the through hole H without using the space on the Y side outside the grommet 10, the wire harness 30 can be connected even if the space on the Y side around the through hole H is narrow. Can branch without difficulty. In addition, since the branch line small-diameter cylindrical portions A and B hold the branch lines 32 and 33 in a bent state, interference between the branch lines 32 and 33 and the indoor in-vehicle component can be prevented.
さらに、グロメット10の大径側開口13aは、図2(A)〜(C)にも示すように、前記巻付片16、17を分岐線32、33に巻きつけてラップしたときに、前記傾斜部16c、17cで形成される縮径部Cと、前記閉じ代部16d、17dの平坦部16e、17eで形成される蓋部Eにより閉鎖されるうえ、分岐線32、33と該グロメット10との隙間も、図3に示すように、前記分岐線用小径筒部A、Bが分岐線32、33の外周に密着して巻きつけられることにより封鎖される。従って、エンジンルームX側のノイズが車室Y側に音漏れすることを防止できる。   Further, as shown in FIGS. 2A to 2C, the large-diameter side opening 13a of the grommet 10 is wound when the winding pieces 16 and 17 are wrapped around the branch lines 32 and 33 and wrapped. In addition to being closed by the reduced diameter portion C formed by the inclined portions 16c and 17c and the lid portion E formed by the flat portions 16e and 17e of the closing margin portions 16d and 17d, the branch lines 32 and 33 and the grommet 10 As shown in FIG. 3, the small-diameter cylindrical portions A and B for branch lines are also sealed by being tightly wound around the outer periphery of the branch lines 32 and 33. Therefore, it is possible to prevent noise on the engine room X side from leaking to the vehicle compartment Y side.
図4(A)(B)は、本発明の第二実施形態を示し、前記一対の巻付片16、17の前記閉じ代部16d、17dに係止構造を設けているが、その他の点は前記第一実施形態と同一構成としている。   4 (A) and 4 (B) show a second embodiment of the present invention, in which a locking structure is provided in the closing margins 16d and 17d of the pair of winding pieces 16 and 17, but other points. Has the same configuration as the first embodiment.
詳しくは、巻付片16の閉じ代部16dの前記平坦部16eの、所要寸法離隔した上下2箇所に、端縁からスリット18、18を設けている。前記巻付片16、17を閉鎖してラップするときは、図4(B)に示すように、前記スリット18、18に他方の巻付片17を端部から挿入する。   Specifically, slits 18 and 18 are provided from the end edge at two upper and lower portions of the flat portion 16e of the closing margin portion 16d of the winding piece 16 that are separated by a required dimension. When the wrapping pieces 16 and 17 are closed and wrapped, the other wrapping piece 17 is inserted into the slits 18 and 18 from the end as shown in FIG.
