本考案は自動車の隔壁板部におけるワイヤーハーネスの
挿通、支持に用いられるグロメットの改良に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a grommet used for inserting and supporting a wire harness in a bulkhead plate of an automobile.
グロメットは、一端にワイヤーハーネスが挿通保持され
る小径の貫通孔が形成され、他端に大径の開口部が形成
されて該他端外周部がパネル貫通孔に取付けられる構造
を有するものであるが、近時において該グロメット部分
における防音効果の向上を意図して、実公昭５３−２４
７３７号公報に示される如く、大径の開口部に防音部材
を嵌合するようにしたものが開発されている。A grommet has a structure in which a small diameter through hole is formed at one end through which a wire harness is inserted and held, a large diameter opening is formed at the other end, and the outer peripheral part of the other end is attached to the panel through hole. However, in recent years, with the intention of improving the soundproofing effect of the grommet part,
As shown in Japanese Patent No. 737, a device in which a soundproof member is fitted into a large diameter opening has been developed.
しかし、該公知技術にあっては、小径筒部は従来のまま
に放置されているので防音効果において完全であるとは
言えないものである。However, in this known technique, the small-diameter cylindrical portion is left as is, so it cannot be said that the soundproofing effect is perfect.
本考案は上記した点に着目して為されたものであり、グ
ロメットの内部に防音筒体を装着して該防音筒体の一端

プ巻きによりワイヤーハーネスに圧着し、その防音性能
を完全に遠戚しつつ、その取付固定が容易に為し得られ
るようにしたものである。The present invention has been developed with the above-mentioned points in mind. A soundproof cylinder is installed inside the grommet, and one end of the soundproof cylinder is brought into close contact with the large diameter opening of the grommet body in a tapered manner. The other end is crimped to the wire harness together with the small-diameter cylindrical portion of the grommet main body by wrapping tape, so that the soundproofing performance is completely maintained and the attachment and fixation can be easily achieved.
以下本考案の一実施例について図面と共に説明すれば、
Ａはゴム製のグロメット本体であり、その内部には貫通
孔１が形成され、該貫通孔１は一側の小径筒部２と他側
の大径のフランジ部３に連通している。An embodiment of the present invention will be described below with reference to the drawings.
A is a grommet body made of rubber, and a through hole 1 is formed inside the grommet body, and the through hole 1 communicates with a small diameter cylindrical portion 2 on one side and a large diameter flange portion 3 on the other side.
フランジ部３の外周部はパネルの貫通孔に取付けられる
ように形成され、その内周部には外方に向けて拡開する
テーパー状の環状嵌合部４が形成されている。The outer periphery of the flange portion 3 is formed to be attached to a through hole of the panel, and the inner periphery thereof is formed with a tapered annular fitting portion 4 that expands outward.
Ｂは防音筒体であり、グロメット本体Ａと略同等の長さ
を有すると共に前記小径筒部２内に嵌合する外径を有し
、−側に外周部をテーパー状にした環状嵌合部６を有し
、他側外周に係合鍔７を有している。Reference numeral B designates a soundproof cylindrical body, which has approximately the same length as the grommet body A, and has an outer diameter that fits into the small diameter cylindrical part 2, and an annular fitting part with an outer peripheral part tapered on the negative side. 6, and has an engaging collar 7 on the outer periphery of the other side.
嵌合部６にはスリット８が設けられている。A slit 8 is provided in the fitting part 6.
上記構成において、ワイヤーハーネスＣに防音筒体Ｂを
被せた後に該ワイヤーハーネスＣをグロメット本体Ａに
挿通し、防音筒体Ｂをグロメット本体Ａの内部に位置さ

ーパー状の環状嵌合部４に対して密接させると共に他側
の係合鍔７をグロメット本体Ａの小径筒部２の外部に位
置させ、この状態で小径筒部２にテープ巻き９を施して
筒体Ｂを介してワイヤーハーネスＣに密着させ、防音性
を確保する。In the above configuration, after the wire harness C is covered with the soundproof cylinder B, the wire harness C is inserted into the grommet body A, and the soundproof cylinder B is positioned inside the grommet body A, and the tapered annular fitting portion thereof is 6 is brought into close contact with the tapered annular fitting part 4 of the flange part 3, and the engagement collar 7 on the other side is positioned outside the small diameter cylindrical part 2 of the grommet main body A, and in this state, The wire harness C is wrapped with tape 9 to be tightly attached to the wire harness C through the cylinder body B, thereby ensuring soundproofing properties.
本考案に係るグロメットは、グロメット本体と同等の長

防音筒体の一側のテーパー状の環状嵌合部をグロメット
本体のフランジ部のテーパー状の環状嵌合部に対して圧
接させると共に他端の係合鍔を筒部に係合させた状態で
該筒部をテープ巻きするので、グロメット本体の両端部
における防音性が確実に遠戚され、しかもこれが１ケ所
のテープ巻きにより安定して保持される実益を有する。In the grommet according to the present invention, a soundproof cylinder having the same length as the grommet main body is placed over a wire harness in advance, and the tapered annular fitting part on one side of the soundproof cylinder is connected to the tapered annular fitting part of the flange part of the grommet main body. The grommet is brought into pressure contact with the annular fitting part, and the cylindrical part is wrapped with tape while the engaging flange at the other end is engaged with the cylindrical part, so that the soundproofing properties at both ends of the grommet body are ensured. Moreover, this has the practical benefit of being stably held by wrapping the tape in one place.
