Description

本発明は、パネルの貫通孔に装着され、外周側にグロメットが嵌合され、内周側にコネクタが装着されるグロメットインナに関するものである。   The present invention relates to a grommet inner that is mounted in a through hole of a panel, a grommet is fitted on the outer peripheral side, and a connector is mounted on the inner peripheral side.

従来、パネルの貫通孔にコネクタを装着する場合、防水性を考慮してパネルの貫通孔にグロメットを装着し、そのグロメットの内部にコネクタを装着する例がある(例えば、特許文献1参照)。   Conventionally, when a connector is attached to a through-hole of a panel, there is an example in which a grommet is attached to the through-hole of the panel in consideration of waterproofness, and a connector is attached to the inside of the grommet (see, for example, Patent Document 1).

このような例では、グロメットによって防水性を確保しながら、コネクタを介してパネルの一方側と他方側の電線を接続することになるが、コネクタで接続しない単なる通過電線を、グロメットの内側を通して、パネルの一方側から他方側へ引き延ばす場合もある。   In such an example, while securing the waterproofness with the grommet, the electric wires on one side and the other side of the panel are connected via the connector, but a simple passing electric wire that is not connected by the connector is passed through the inside of the grommet, In some cases, the panel is extended from one side to the other side.

このような場合は、グロメットに対してのコネクタの装着性を考慮して、硬質材料製の筒状のグロメットインナをグロメットの内周側に配設し、これをパネルの貫通孔に装着すると共に、そのグロメットインナの周壁部に形成した挿入孔に通過電線を通して、その上で、挿入孔の内側の隔壁で画成された空間に、コネクタを装着するようにしている。
特開2001−283977号公報
In such a case, in consideration of the mountability of the connector to the grommet, a cylindrical grommet inner made of a hard material is disposed on the inner peripheral side of the grommet, and this is installed in the through hole of the panel. The passing wire is passed through the insertion hole formed in the peripheral wall portion of the grommet inner, and the connector is mounted on the space defined by the partition wall inside the insertion hole.
JP 2001-283777 A

ところで、従来では、通過電線をグロメットインナの周壁部に設けた挿入孔に通すに当たり、挿入孔の一端側の開口から他端側の開口へ向かって通過電線を通しているのが普通であるが、挿入孔はそれ自体が小さいものであるため、その作業が非常にやりにくいという問題があった。   By the way, conventionally, when passing the passing wire through the insertion hole provided in the peripheral wall portion of the grommet inner, it is normal to pass the passing wire from the opening on one end side of the insertion hole toward the opening on the other end. Since the holes themselves are small, there is a problem that the operation is very difficult.

本発明は、上記事情を考慮し、より簡単に通過電線を通すことのできるグロメットインナを提供することを目的とする。   In consideration of the above circumstances, an object of the present invention is to provide a grommet inner that allows a passing wire to pass through more easily.

請求項1の発明のグロメットインナは、パネルの貫通孔に装着され、外周側に軟質材料よりなるグロメットの嵌合周壁が嵌合され、内周側にコネクタが装着される硬質材料製の筒状体であり、自身の周壁部に、前記パネル及び前記グロメットの電線挿通部を貫通する方向に通過する通過電線の挿入孔が形成されたグロメットインナにおいて、前記通過電線の挿入孔を画成すると共に前記コネクタの装着空間を画成する内側隔壁に、前記コネクタの装着空間側から前記挿入孔に対して前記通過電線を挿入し得るスリットを形成し、このスリットが、前記コネクタの装着空間側から見てクランク形状に形成されていることを特徴としている。 The grommet inner of the invention according to claim 1 is mounted in the through hole of the panel, is fitted with a fitting peripheral wall of a grommet made of a soft material on the outer peripheral side, and is a cylindrical shape made of a hard material with a connector attached on the inner peripheral side A grommet inner in which an insertion hole for a passing wire passing through the panel and the wire insertion portion of the grommet is formed on the peripheral wall portion of the grommet inner. A slit through which the passing electric wire can be inserted into the insertion hole from the connector mounting space side is formed in the inner partition that defines the connector mounting space , and the slit is viewed from the connector mounting space side. It is characterized by being formed into a crank shape .

請求項1の発明によれば、通過電線の挿入孔とコネクタの装着空間を画成する内側隔壁に形成したスリットを通して、コネクタの装着空間側から通過電線を挿入孔に挿入することができるので、小さな挿入孔の開口端から電線を挿入するのと比べて、通過電線の挿入作業が簡単にできるようになり、作業性が向上する。特に、スリットを、コネクタの装着空間側から見てクランク形状に形成したので、挿入するときに電線を多少曲げながら、そのクランク形状のスリットを通して挿入孔に挿入すれば、その後は電線が自然に直線状に延びることで、抜けにくくなる。従って、後からコネクタをグロメットインナの内側に装着する時に、せっかく先に挿入孔に入れた通過電線が再びコネクタの装着空間側に出てしまって、コネクタの挿入の邪魔になるというようなことがない。この場合、スリットの間隔を、曲げた状態の通過電線が通るだけの間隔に設定しておけば、電線は自然状態で直線状に延びて簡単には小さく曲がらないので、抜ける心配はない。 According to the invention of claim 1, since the passing wire can be inserted into the insertion hole from the mounting space side of the connector through the slit formed in the insertion hole of the passing wire and the inner partition that defines the mounting space of the connector, Compared with inserting an electric wire from the opening end of a small insertion hole, the insertion operation of a passing electric wire can be performed easily, and workability is improved. In particular, the slit is formed in a crank shape when viewed from the mounting space side of the connector, so if you insert the wire into the insertion hole through the crank-shaped slit while bending the wire slightly when inserting it, the wire will naturally straighten after that. It becomes difficult to come out by extending in the shape. Therefore, when the connector is attached later to the inner side of the grommet inner, the passing electric wire previously put into the insertion hole again comes out to the connector installation space side, which may obstruct the insertion of the connector. Absent. In this case, if the interval between the slits is set to an interval that allows the passing electric wire in a bent state to pass, the electric wire extends in a straight line in a natural state and does not bend easily, so there is no fear of coming off.

以下、本発明の実施形態を図面を参照しながら説明する。   Embodiments of the present invention will be described below with reference to the drawings.

It is an operation process figure in the case of putting a passing electric wire in an insertion hole through a slit. 5 is a side view showing a state in which the grommet is fitted to the outer periphery of the grommet inner and mounted in the through hole of the panel, FIG. 6 is a cross-sectional view taken along the line VI-VI in FIG. 5, and FIG. VII-VII arrow sectional view, FIG. 8 is a sectional view taken along arrow VIII-VIII in FIG. 6, FIG. 9 is a sectional view taken along arrow IX-IX in FIG. 6, and FIG. 10 is a sectional view taken along arrow XX in FIG. is there.

このグロメットインナ10は、図8に示すように、パネルPの貫通孔Paに装着され、外周側に軟質材料(ゴム等)よりなるグロメット70が嵌合され、内周側にコネクタ100が装着される硬質材料(硬質樹脂)製の筒状体であり、他の図にも示すように、自身の周壁部11の対向する2箇所に、パネルPを貫通する方向に通過する通過電線300の挿入孔20が形成されたものである。   As shown in FIG. 8, the grommet inner 10 is mounted in the through hole Pa of the panel P, the grommet 70 made of a soft material (rubber or the like) is fitted on the outer peripheral side, and the connector 100 is mounted on the inner peripheral side. Insertion of passing electric wires 300 that pass through the panel P in two opposing positions of the peripheral wall 11 as shown in other figures. The hole 20 is formed.

通過電線300の挿入孔20は、外側隔壁13と内側隔壁14の間に確保されており、何本かの電線が挿入できるような大きさに形成されている。内側隔壁14は、通過電線300の挿入孔20を画成すると共に、コネクタ100を装着するための角形の装着空間12を画成するものであり、その内側隔壁14には、コネクタの装着空間12側から挿入孔20に対して通過電線300を挿入し得るように、スリット15が形成されている。このスリット15は、コネクタの装着空間12側から見てクランク形状に形成されており、図3に示すように、一端側のスリット部15aと他端側のスリット部15bとが内側隔壁14の周方向にずれて形成されている。   The insertion hole 20 of the passing wire 300 is secured between the outer partition wall 13 and the inner partition wall 14 and is formed in a size that allows several wires to be inserted. The inner partition wall 14 defines the insertion hole 20 of the passing wire 300 and also defines a rectangular mounting space 12 for mounting the connector 100. The inner partition wall 14 includes a connector mounting space 12. A slit 15 is formed so that the passing electric wire 300 can be inserted into the insertion hole 20 from the side. The slit 15 is formed in a crank shape when viewed from the connector mounting space 12 side. As shown in FIG. 3, the slit portion 15 a on one end side and the slit portion 15 b on the other end side surround the inner partition wall 14. It is formed to be shifted in the direction.

また、グロメットインナ10の周壁部11には、その外周部に、グロメット70のフランジ部75の嵌合する鍔部17が突設されると共に、パネルPの貫通孔Paの周縁に対して係合する係止突起18と、パネルPの貫通孔Paの周縁に対してロックする可撓ロック爪19とが設けられている。   Further, the peripheral wall portion 11 of the grommet inner 10 is provided with a flange portion 17 fitted to the flange portion 75 of the grommet 70 on the outer peripheral portion thereof, and is engaged with the peripheral edge of the through hole Pa of the panel P. A locking projection 18 to be fixed and a flexible lock claw 19 to lock the peripheral edge of the through hole Pa of the panel P are provided.

グロメットインナ10をパネルPの貫通孔Paに装着する場合は、グロメットインナ10をやや傾けながら、係止突起18のある側から先に貫通孔Paに潜らせ、次いで、可撓ロック爪19のある側を貫通孔Paに押し込む。そうすると、可撓ロック爪19が撓みながら貫通孔Paの周縁に係合ロックする。   When the grommet inner 10 is mounted in the through hole Pa of the panel P, the grommet inner 10 is slightly inclined and is first hidden in the through hole Pa from the side where the locking projection 18 is present, and then the flexible lock claw 19 is provided. The side is pushed into the through hole Pa. Then, the flexible lock claw 19 is engaged and locked to the periphery of the through hole Pa while being bent.

一方、グロメット70には、前述のフランジ部75の前面にリップ状のシール部76が設けられ、グロメット70を装着した状態でグロメットインナ10をパネルPの貫通孔Paに装着することにより、シール部76がパネルPの板面に圧接して、シール性を発揮するようになっている。また、フランジ部75の後側には、グロメットインナ10の周壁部11の外周に嵌合する嵌合周壁71が設けられ、その後側には袋壁72が設けられ、その更に後側に筒状の電線挿通部73が設けられている。この場合、電線挿通部73は、図10に示すように、コネクタ100の中心部から偏心させた位置に設けられている。   On the other hand, the grommet 70 is provided with a lip-shaped seal portion 76 on the front surface of the flange portion 75 described above, and the grommet inner 10 is mounted in the through hole Pa of the panel P in a state where the grommet 70 is mounted. 76 is brought into pressure contact with the plate surface of the panel P so as to exhibit a sealing property. Further, on the rear side of the flange portion 75, a fitting peripheral wall 71 that is fitted to the outer periphery of the peripheral wall portion 11 of the grommet inner 10 is provided, a bag wall 72 is provided on the rear side thereof, and a tubular shape is further provided on the rear side thereof. The electric wire insertion part 73 is provided. In this case, the electric wire insertion part 73 is provided in the position eccentric from the center part of the connector 100, as shown in FIG.

このグロメットインナ10を使用する場合は、グロメットインナ10の外周にグロメット70を装着し、その状態でパネルPの貫通孔Paにグロメットインナ10を装着する。また、それと前後して、通過電線300をグロメットインナ10の挿入孔20に挿入する。そして、その後からグロメットインナ10の装着空間12にコネクタ100を挿入して係合させる。   When this grommet inner 10 is used, the grommet 70 is attached to the outer periphery of the grommet inner 10 and the grommet inner 10 is attached to the through hole Pa of the panel P in this state. Further, before and after that, the passing electric wire 300 is inserted into the insertion hole 20 of the grommet inner 10. Thereafter, the connector 100 is inserted into the mounting space 12 of the grommet inner 10 and engaged.

ところで、グロメットインナ10の挿入孔20に通過電線300を挿入する際に、挿入孔20とコネクタの装着空間12を画成する内側隔壁14に形成したスリット15を通して、コネクタの装着空間12側から通過電線300を挿入孔20に挿入することができるので、小さな挿入孔20の開口端から電線300を挿入するのと比べて、通過電線300の挿入作業が簡単にできるようになり、作業性が向上する。   By the way, when the passing wire 300 is inserted into the insertion hole 20 of the grommet inner 10, it passes from the insertion space 12 side of the connector through the slit 15 formed in the inner partition 14 that defines the insertion hole 20 and the connector mounting space 12. Since the electric wire 300 can be inserted into the insertion hole 20, the insertion operation of the passing electric wire 300 can be performed more easily than when the electric wire 300 is inserted from the opening end of the small insertion hole 20, and the workability is improved. To do.

特に、スリット15は、コネクタの装着空間12側から見てクランク形状に形成してあるので、図4(a)、(b)に示すように、挿入するときに電線300を多少曲げながら、そのクランク形状のスリット15を通して挿入孔20に挿入すれば、その後は図4(c)に示すように、電線300が自然に直線状に延びることで、抜けにくくなる。従って、後からコネクタ100をグロメットインナ10の内側に装着する時に、せっかく先に挿入孔20に入れた通過電線300が再びコネクタの装着空間12側に出てしまって、コネクタ100の挿入の邪魔になるというようなことがない。この場合、スリット15の間隔を、曲げた状態の通過電線300が通るだけの間隔に設定しておけば、電線300は自然状態で直線状に延びて簡単には小さく曲がらない性質を持つので、抜ける心配はない。   In particular, since the slit 15 is formed in a crank shape when viewed from the connector mounting space 12 side, as shown in FIGS. 4 (a) and 4 (b), the wire 300 is slightly bent while being inserted. If it inserts in the insertion hole 20 through the crank-shaped slit 15, after that, as shown in FIG.4 (c), it will become difficult to pull out because the electric wire 300 will naturally extend linearly. Therefore, when the connector 100 is attached to the inner side of the grommet inner 10 later, the passing wire 300 previously inserted into the insertion hole 20 comes out again to the connector mounting space 12 side, which obstructs the insertion of the connector 100. There is no such thing as. In this case, if the interval between the slits 15 is set to an interval that allows the passing electric wire 300 in a bent state to pass, the electric wire 300 has a property that extends in a straight line in a natural state and does not bend easily. There is no worry about getting out.

また、図4(d)に示すように、裸電線以外に複数本(この場合は2本)の電線301が入った細径のチューブ400等をクランク形状のスリット15を通して挿入孔20に挿入して係止すれば、結果的に複数の電線301も保持することができる。   Further, as shown in FIG. 4D, a thin tube 400 or the like containing a plurality of (in this case, two) wires 301 in addition to the bare wires is inserted into the insertion hole 20 through the crank-shaped slit 15. As a result, the plurality of electric wires 301 can also be held.

さらに、図4(e)に示すように、裸電線以外に複数本(この場合は2本)の電線301が入った太径のチューブ400′等をスリット15を通して挿入孔20に挿入して係止すれば、結果的に複数の電線301も保持することができる。この場合には、他端側のスリット部15bがないものを用いる。   Further, as shown in FIG. 4 (e), a large-diameter tube 400 'or the like containing a plurality of (in this case, two) wires 301 in addition to the bare wires is inserted into the insertion hole 20 through the slit 15, and the engagement is performed. If it stops, the some electric wire 301 can also be hold | maintained as a result. In this case, one without the slit portion 15b on the other end side is used.
