Description

本発明は、車両に配索するワイヤハーネスに外装して車体パネルの貫通穴に装着するグロメットに関し、詳しくは、右ハンドル車と左ハンドル車とでグロメットに貫通させるワイヤハーネスの屈曲方向が右向きと左向きとに相違しても共用可能とするものである。 The present invention relates to a grommet that is externally mounted on a wire harness that is routed to a vehicle and is mounted in a through hole of a vehicle body panel. Even if it is different from the left direction, it can be shared.

この種のグロメットは、図１４に示すように、ゴムまたはエラストマーからなる弾性体で成形され、車体パネルＰに設けた貫通穴Ｈの内周面を通す位置でワイヤハーネスＷ／Ｈの外周面に装着される。該グロメット１００はワイヤハーネスＷ／Ｈを密着して挿通する小径筒部１０１の一端から傾斜筒部１０２が突出し、該傾斜筒部１０２の外周面に設けた環状の車体係止凹部１０３に貫通穴Ｈの周縁を落とし込んで係止している。
ワイヤハーネスを配索する自動車が、右ハンドル車と左ハンドル車と相違すると、ワイヤハーネスに外装するグロメット１００の小径筒部１０１の曲げ方向が図１４（Ａ）（Ｂ）に示すように左右対称方向になる場合が多い。また、右ハンドル車同士であっても車種の相違によって、同一箇所に配索するワイヤハーネスでグロメットの筒部の曲げ方向が相違する場合もある。 As shown in FIG. 14, this type of grommet is formed of an elastic body made of rubber or elastomer, and is formed on the outer peripheral surface of the wire harness W / H at a position passing through the inner peripheral surface of the through hole H provided in the vehicle body panel P. Installed. In the grommet 100, an inclined cylindrical portion 102 protrudes from one end of a small diameter cylindrical portion 101 through which the wire harness W / H is closely inserted, and a through-hole is formed in an annular vehicle body engaging concave portion 103 provided on the outer peripheral surface of the inclined cylindrical portion 102. The periphery of H is dropped and locked.
When the automobile for wiring the wire harness is different from the right-hand drive car and the left-hand drive car, the bending direction of the small-diameter cylindrical portion 101 of the grommet 100 that is externally mounted on the wire harness is bilaterally symmetric as shown in FIGS. In many cases, the direction. Even in the case of right-hand drive cars, the bending direction of the tubular portion of the grommet may be different due to the wire harness routed in the same location due to the difference in the vehicle type.

グロメットを装着する貫通穴が同一の大きさであっても、グロメットのワイヤハーネスを密着して挿通する筒部の方向が３０度以上相違すると同一のグロメットを用いることはできず、筒部の曲げ方向を相違させたグロメットを製造している。そのため、グロメットの品番が多くなり、製造コストが高くなると共に管理コストも増大する問題がある。 Even if the through-holes for attaching the grommets are the same size, if the direction of the cylindrical part through which the grommet wire harness is closely inserted is different by 30 degrees or more, the same grommet cannot be used and the cylindrical part is bent. Manufactures grommets with different directions. Therefore, there are problems that the number of grommets increases, the manufacturing cost increases, and the management cost also increases.

前記問題に鑑みて、曲げ方向が左右相違する場合にも共用で用いることができるグロメットが提案されている。例えば、本出願人の先願に係わる特開平８−１０６８３１号公報で提案したグロメット１２０は図１５（Ａ）（Ｂ）に示すように、車体係止凹部１０３を設けた傾斜筒部１０２に蛇腹筒部１２１を介して小径筒部１０１を同一軸線上に設け、該小径筒部１０１に係止片１２２を突設し、該係止片１２２に係止穴１２４を設けると共に、傾斜筒部１０２の外周面に係止突起１２５を設けている。該グロメットでは、小径筒部１０１を所要方向に曲げ、該小径筒部１０１から突設した係止片１２２の係止穴１２４を係止突起１２５に挿入係止して小径筒部１０１を所要の曲げ姿勢に保持している。 In view of the above problems, grommets that can be used in common even when the bending directions are different from each other have been proposed. For example, as shown in FIGS. 15A and 15B, the grommet 120 proposed in Japanese Patent Application Laid-Open No. 8-106831 related to the prior application of the present applicant is accordion to the inclined cylindrical portion 102 provided with the vehicle body locking recess 103. The small-diameter cylindrical portion 101 is provided on the same axis via the cylindrical portion 121, the locking piece 122 projects from the small-diameter cylindrical portion 101, the locking piece 122 is provided with a locking hole 124, and the inclined cylindrical portion 102 is provided. A locking projection 125 is provided on the outer peripheral surface of the. In the grommet, the small-diameter cylindrical portion 101 is bent in a required direction, and the locking hole 124 of the locking piece 122 protruding from the small-diameter cylindrical portion 101 is inserted and locked into the locking projection 125 so that the small-diameter cylindrical portion 101 is It is held in a bending posture.

特開平８−１０６８３１号公報Japanese Patent Laid-Open No. 8-106831

前記図１５に示すグロメットでは、小径筒部１０１を傾斜筒部１０２に対して所要方向に曲げるために蛇腹筒部１２１を介在させる必要がある。よって、車体パネルＰの貫通穴Ｈに装着した位置から小径筒部１０１を曲げる位置までに、蛇腹筒部１２１の長さ以上の寸法が必要となる。そのため、車体パネルＰに近接して外部干渉材があり、小径筒部１０１を車体パネルＰに近接させて急激に曲げる必要がある場合には、採用できない問題がある。また、係止片１２２の係止穴１２４に係止突起１２５を挿入係止するだけであるため、ワイヤハーネスに引っ張り負荷が作用すると、係止が外れ、小径筒部を曲げ方向に保持できなくなるおそれもある。 In the grommet shown in FIG. 15, it is necessary to interpose the bellows cylinder portion 121 in order to bend the small diameter cylinder portion 101 with respect to the inclined cylinder portion 102 in a required direction. Therefore, the dimension more than the length of the bellows cylinder part 121 is required from the position where it is mounted in the through hole H of the vehicle body panel P to the position where the small diameter cylinder part 101 is bent. Therefore, when there is an external interference material in the vicinity of the vehicle body panel P and the small-diameter cylindrical portion 101 needs to be bent close to the vehicle body panel P, there is a problem that cannot be adopted. Further, since only the locking projection 125 is inserted and locked into the locking hole 124 of the locking piece 122, when a tensile load is applied to the wire harness, the locking is released and the small diameter cylindrical portion cannot be held in the bending direction. There is also a fear.
