Description

本発明は、パネルの取付孔と係止可能に形成されたクリップが、前記取付孔に挿通される電線に一体成形されたクリップ付ワイヤハーネスに関する。   The present invention relates to a wire harness with a clip in which a clip formed so as to be able to be locked with a mounting hole of a panel is integrally formed with an electric wire inserted through the mounting hole.

自動車には、種々の電子機器と電装品とが搭載されている。これらの電子機器と電装品とにバッテリなどの電源等からの電力や制御装置からの制御信号などを伝達する手段として、ワイヤハーネスが用いられている。   Various electronic devices and electrical components are mounted on automobiles. A wire harness is used as means for transmitting electric power from a power source such as a battery or a control signal from a control device to these electronic devices and electrical components.

ワイヤハーネスは、自動車等の車体を構成するパネルに所要の配索形態で配索されている。ワイヤハーネスは、バックドアと車室内とに跨って配索される際には、前記バックドアのインナーパネルの取付孔にグロメットが嵌合され、前記取付孔に嵌合されたグロメットの挿通孔を前記ワイヤハーネが挿通して配索される。このように、パネルにグロメットを嵌合し、ワイヤハーネスを配索したものが種々提案されている（例えば、特許文献１〜特許文献３参照。）。   The wire harness is routed in a required routing form on a panel constituting a vehicle body such as an automobile. When the wire harness is routed across the back door and the passenger compartment, the grommet is fitted into the mounting hole of the inner panel of the back door, and the grommet insertion hole fitted into the mounting hole is inserted. The wire harness is inserted and routed. Thus, various things which fitted the grommet to the panel and wired the wire harness are proposed variously (for example, refer to patent documents 1-3).

特開２００５−１７４８５８号公報JP 2005-174858 A 特開２００４−２３４９０４号公報JP 2004-234904 A 特開２００２−３６９３４７号公報JP 2002-369347 A

しかしながら、特許文献１および特許文献２に記載のワイヤハーネスは、パネルの取付孔に嵌合されるグロメットが、天然ゴムあるいは合成ゴムのような弾性材料によって形成されているため、摩擦力が高く、パネルの取付孔への組み付け性が悪い。   However, the wire harnesses described in Patent Document 1 and Patent Document 2 have a high frictional force because the grommet fitted into the mounting hole of the panel is formed of an elastic material such as natural rubber or synthetic rubber. The assembly to the panel mounting hole is poor.

前記ワイヤハーネスは、ゴム製のグロメットが優れた止水機能を発揮するが、前記バックドア等のように自然に水が抜けるため止水機能が不要な箇所に前記グロメットを使用することは、過剰性能となっている。さらに、ゴム製のグロメットが比較的高価であるため、ワイヤハーネスの製造コストが上昇する。   The wire harness has a rubber grommet that exhibits an excellent water stop function, but it is excessive to use the grommet in a place where the water stop function is unnecessary because the water naturally drains out, such as the back door. It has become a performance. Furthermore, since rubber grommets are relatively expensive, the manufacturing cost of the wire harness increases.

また、特許文献３に記載のワイヤハーネスは、パネルの取付孔に係止されるグロメットが、伸縮性や弾性のない合成樹脂によって形成されているため、ワイヤハーネスの外形よりも挿通孔が大径に形成されており、前記グロメットが大型化する。また、前記グロメットは、挿通孔がワイヤハーネスの外形よりも大径に形成されているため、外観がよくない。   Moreover, since the grommet latched by the mounting hole of a panel is formed of the synthetic resin which does not have elasticity or elasticity, the insertion hole is larger diameter than the external shape of a wire harness. The grommet is enlarged. Moreover, since the insertion hole has a larger diameter than the outer shape of the wire harness, the outer appearance of the grommet is not good.

前記ワイヤハーネスは、グロメットが複数の部材から構成されているため、前記グロメットの部品点数が多くなって高価となる。また、構造が複雑化して組み立て作業にかかる所要時間が長時間化する。また、グロメットを組み立てた後、ワイヤハーネスを挿通孔に挿通させる作業が必要である。また、係止羽根が外部に向かって突出して露出されているため、前記係止羽根が破損する虞がある。   In the wire harness, since the grommet is composed of a plurality of members, the number of parts of the grommet is increased and the cost is increased. In addition, the structure becomes complicated and the time required for the assembly work becomes longer. Further, after assembling the grommet, it is necessary to insert the wire harness into the insertion hole. Further, since the locking blade protrudes outward and is exposed, the locking blade may be damaged.

本発明は、かかる問題を解決することを目的とするものである。即ち、本発明は、パネルの取付孔と係止可能に形成されたクリップが、前記取付孔に挿通される電線に一体成形されたクリップ付ワイヤハーネスを提供することを目的とする。   The present invention aims to solve such problems. That is, an object of the present invention is to provide a wire harness with a clip in which a clip formed so as to be able to be locked with a mounting hole of a panel is integrally formed with an electric wire inserted through the mounting hole.

前記課題を解決し目的を達成するために、請求項１に記載された発明は、パネルの取付孔に係止されるクリップが電線に一体成形されたクリップ付ワイヤハーネスであって、前記クリップは、前記取付孔に重ねられると共に前記パネルに当接される皿状部と、前記皿状部から立設され前記取付孔に挿通される本体部と、前記取付孔の周縁部に係止される係止片と、を備え、前記電線が、前記皿状部と前記本体部とを貫通して設けられていることを特徴とするクリップ付ワイヤハーネスである。   In order to solve the above problems and achieve the object, the invention described in claim 1 is a wire harness with a clip in which a clip to be locked to a mounting hole of a panel is integrally formed with an electric wire, and the clip is , A dish-shaped part that is superimposed on the mounting hole and is in contact with the panel; a main body part that is erected from the dish-shaped part and is inserted into the mounting hole; and a peripheral part of the mounting hole. A wire harness with a clip, wherein the wire is provided so as to penetrate through the dish-like portion and the main body portion.

請求項２に記載された発明は、前記皿状部には、前記パネルに対向する面に凹部が設けられていることを特徴とする請求項１に記載のクリップ付ワイヤハーネスである。   The invention described in claim 2 is the wire harness with clip according to claim 1, wherein the dish-like portion is provided with a recess on a surface facing the panel.

請求項１に記載された発明によれば、クリップ付ワイヤハーネスは、パネルの取付孔にクリップを挿通させるだけで、前記クリップ付ワイヤハーネスが前記取付孔に係止される。このため、クリップ付ワイヤハーネスは、従来のグロメットよりも容易且つ迅速に、パネルの取付孔に取り付けることができる。従って、クリップ付ワイヤハーネスをパネルに取り付ける作業時間が短縮される。   According to the first aspect of the present invention, the clip-attached wire harness is engaged with the attachment hole only by inserting the clip through the attachment hole of the panel. For this reason, the wire harness with a clip can be attached to the attachment hole of the panel more easily and more quickly than the conventional grommet. Therefore, the work time for attaching the wire harness with clip to the panel is shortened.

また、クリップ付ワイヤハーネスは、電線にクリップが一体成形されて形成されているため、前記クリップを組み立てる工程、前記クリップを電線に固定させる工程などが省略されるため、前記クリップ付ワイヤハーネスの製造時間が短縮される。   Moreover, since the clip-attached wire harness is formed by integrally forming the clip on the electric wire, the step of assembling the clip, the step of fixing the clip to the electric wire, and the like are omitted. Time is shortened.

また、クリップ付ワイヤハーネスは、従来のグロメットにおいて設けられていた電線の挿通孔が不要となるため、パネルの取付孔の孔径が必要最小となり、クリップが小型化される。このため、良好な外観となる。   Moreover, since the wire harness with a clip does not require the insertion hole of the electric wire provided in the conventional grommet, the hole diameter of the mounting hole of a panel becomes the minimum required, and a clip is reduced in size. For this reason, it becomes a favorable external appearance.

そして、クリップ付ワイヤハーネスは、ゴム等よりも安価な合成樹脂製であるため、従来のグロメットを使用したワイヤハーネスよりも安価となる。   And since the wire harness with a clip is made of a synthetic resin that is cheaper than rubber or the like, it becomes less expensive than a wire harness using a conventional grommet.

請求項２に記載された発明によれば、クリップ付ワイヤハーネスは、皿状部に設けられた凹部によって係止片の自由端が当該皿状部に接触しないため、前記係止片の自由端が互いにより近接して、パネルの取付孔の周縁部と内周面とに確り係止されると共に前記皿状部が前記パネルに当接される。このため、クリップ付ワイヤハーネスは、電線の軸方向のガタツキが確実に防止される。   According to the invention described in claim 2, since the free end of the locking piece does not come into contact with the dish-shaped portion due to the recess provided in the dish-shaped portion, the free end of the locking piece Are closer to each other and are securely locked to the peripheral edge portion and the inner peripheral surface of the mounting hole of the panel, and the dish-like portion is brought into contact with the panel. For this reason, the wire harness with a clip is reliably prevented from rattling in the axial direction of the electric wire.

以下、本発明の実施形態について、図１〜図６を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to FIGS.

本発明の一実施形態にかかるワイヤハーネス１は、図１に示すように、パネル１２の取付孔１３に挿通される電線３と、前記取付孔１３に係止可能に形成されたクリップ２とを備え、当該クリップ２が前記電線３に一体成形されて形成されている。   As shown in FIG. 1, a wire harness 1 according to an embodiment of the present invention includes an electric wire 3 inserted into an attachment hole 13 of a panel 12 and a clip 2 formed to be able to be locked in the attachment hole 13. The clip 2 is formed integrally with the electric wire 3.

電線３は、図５に示すように、導電性の芯線３ａと、絶縁性の被覆部３ｂとを有している。芯線３ａは、複数本の金属からなる導線が撚られて形成されている。被覆部３ｂは、前記芯線３ａを被覆しており、ポリ塩化ビニル樹脂などの合成樹脂によって形成されている。このため、電線３の外表面は、前記被覆部３ｂの外表面となっている。なお、電線３は、複数本の電線３が纏められたもの、あるいは、ワイヤハーネス用テープや結束バンド等によって複数本の電線３が束ねられた電線束であっても良い。なお、芯線３ａは、一本の芯線から構成されても良い。   As illustrated in FIG. 5, the electric wire 3 includes a conductive core wire 3 a and an insulating covering portion 3 b. The core wire 3a is formed by twisting conductive wires made of a plurality of metals. The covering portion 3b covers the core wire 3a and is made of a synthetic resin such as a polyvinyl chloride resin. For this reason, the outer surface of the electric wire 3 is the outer surface of the said coating | coated part 3b. In addition, the electric wire 3 may be a wire bundle in which a plurality of electric wires 3 are bundled, or a wire bundle in which a plurality of electric wires 3 are bundled with a tape for wire harness, a binding band, or the like. In addition, the core wire 3a may be comprised from one core wire.

クリップ２は、図１に示すように、前記電線３の同軸上に設けられている。クリップ２は、前記電線３に一体成形されて形成されている。クリップ２は、可撓性を有するポリプロピレン樹脂などの合成樹脂によって形成されている。クリップ２は、前記取付孔１３に重ねられた際に前記パネルの表面に当接する皿状部４と、前記皿状部４から前記電線３に沿って延長された本体部５と、前記本体部５の両側面に立設され前記皿状部４に向かって延長された一対の係止片６と、を備えている。   As shown in FIG. 1, the clip 2 is provided on the same axis as the electric wire 3. The clip 2 is formed integrally with the electric wire 3. The clip 2 is formed of a synthetic resin such as a polypropylene resin having flexibility. The clip 2 includes a plate-like portion 4 that contacts the surface of the panel when the clip 2 is overlaid on the mounting hole 13, a main body portion 5 that extends from the plate-like portion 4 along the electric wire 3, and the main body portion. 5 and a pair of locking pieces 6 extending toward the dish-like portion 4.

本体部５は、図１および図２に示すように、前記電線３を中心とする同軸上に設けられている。本体部５は、前記電線３の外表面に一体成形されて形成されている。前記本体部５には、先端部が、前記取付孔１３の内周面の形状に沿って円弧状に形成された膨出部が設けられている。このため、前記取付孔１３に前記クリップ付ワイヤハーネス１が係止された時に、前記クリップ２が前記電線３の長手方向に直交する方向のガタツキが防止される。   As shown in FIGS. 1 and 2, the main body 5 is provided coaxially with the electric wire 3 as the center. The main body 5 is formed integrally with the outer surface of the electric wire 3. The main body portion 5 is provided with a bulging portion whose tip portion is formed in an arc shape along the shape of the inner peripheral surface of the mounting hole 13. For this reason, when the clip-attached wire harness 1 is locked in the mounting hole 13, rattling of the clip 2 in a direction orthogonal to the longitudinal direction of the electric wire 3 is prevented.

一対の係止片６は、図６に示すように、前記本体部５の両側面のそれぞれから立設されると共に前記皿状部４に向かって延長されている。係止片６は、図２に示すように、前記皿状部４に向かうに従って徐々に互いに離間するように傾斜して形成されている。係止片６は、揺動可能に形成され、当該係止片６の揺動方向が、前記電線３の長手方向に直交する方向に形成されている。   As shown in FIG. 6, the pair of locking pieces 6 are erected from both side surfaces of the main body 5 and extended toward the dish-shaped portion 4. As shown in FIG. 2, the locking pieces 6 are formed so as to be gradually separated from each other toward the dish-like portion 4. The locking piece 6 is formed to be swingable, and the swinging direction of the locking piece 6 is formed in a direction perpendicular to the longitudinal direction of the electric wire 3.

皿状部４は、図２に示すように、前記係止片６が揺動した際に、当該係止片の自由端が前記皿状部４に接触させない凹部８を備えている。凹部８は、前記皿状部４の前記パネルに対向する面に溝状に形成されている。   As shown in FIG. 2, the dish-shaped portion 4 includes a recess 8 that prevents the free end of the locking piece from contacting the dish-shaped portion 4 when the locking piece 6 swings. The recess 8 is formed in a groove shape on the surface of the dish-like portion 4 facing the panel.

上述のクリップ付ワイヤハーネス１が成形される金型２１は、図３に示すように、水平割金型であって、上型２２と下型２３とから構成されている。上型２２と下型２３とには、それぞれ、前記電線３の外形に沿って形成された線条キャビティ２５と、前記クリップ２の外形に沿って形成されたクリップ用キャビティ２４と、が設けられている。下型２３は、図４に示すように、線条キャビティ２５とクリップ用キャビティ２４とがそれぞれ上向きに形成されている。線条キャビティ２５は、図４に示すように、上型２２と下型２３との両端から前記電線３を外部に導出させる導出口２６がそれぞれ設けられている。なお、金型２１は、垂直割金型であってもよい。   As shown in FIG. 3, the mold 21 in which the above-described clip-attached wire harness 1 is molded is a horizontal mold, and includes an upper mold 22 and a lower mold 23. The upper mold 22 and the lower mold 23 are each provided with a linear cavity 25 formed along the outer shape of the electric wire 3 and a clip cavity 24 formed along the outer shape of the clip 2. ing. As shown in FIG. 4, the lower mold 23 has a linear cavity 25 and a clip cavity 24 formed upward. As shown in FIG. 4, the linear cavity 25 is provided with outlets 26 through which the electric wires 3 are led out from both ends of the upper mold 22 and the lower mold 23. The mold 21 may be a vertical split mold.

なお、金型２１は、前記クリップ用キャビティ２４が、前記線条キャビティ２５上に複数個設けられていても良い。この場合の金型２１は、複数個のクリップ用キャビティ２４が、クリップ付ワイヤハーネス１が前記パネル１２に取り付けられる時に、複数のクリップ２が前記パネル１２の取付孔１３に係止可能となる位置に配置される。即ち、複数のクリップ２は、電線３に対する相対的な位置が前記パネル１２の前記取付孔１３に係止可能となる位置に設けられる。   The mold 21 may be provided with a plurality of the clip cavities 24 on the linear cavities 25. The mold 21 in this case has a plurality of clip cavities 24 at positions where the plurality of clips 2 can be locked in the mounting holes 13 of the panel 12 when the clip-attached wire harness 1 is attached to the panel 12. Placed in. That is, the plurality of clips 2 are provided at positions where the relative positions with respect to the electric wires 3 can be locked in the mounting holes 13 of the panel 12.

本発明でいう、複数のクリップ２が、電線３に対する相対的な位置がパネル１２の取付孔１３に係止可能となる位置に設けられているとは、線条キャビティ２５に対してクリップ付ワイヤハーネス１の設計時の相対的な位置に保たれたクリップ用キャビティ２４内に溶融樹脂を射出成形して得られたクリップ付ワイヤハーネス１において、複数のクリップ２の電線３に対する相対的な位置が、射出成形時に生じる誤差を除くと、設計時に定められた位置となっていることをいう。   In the present invention, the plurality of clips 2 are provided at positions where the relative positions with respect to the electric wires 3 can be locked in the mounting holes 13 of the panel 12. In the clip-attached wire harness 1 obtained by injection molding of the molten resin into the clip cavity 24 maintained at the relative position when the harness 1 is designed, the relative positions of the plurality of clips 2 with respect to the electric wires 3 are Excluding errors that occur during injection molding, it means that the position is determined at the time of design.

金型２１によって成形されたクリップ付ワイヤハーネス１は、例えば、バックドアと車室内とに跨って配索される際には、図５に示すように、電線３と本体部５とが前記バックドアのインナーパネル１２の取付孔１３内に侵入すると、一対の係止片６のそれぞれの自由端が互いに近接する方向に弾性変形される。このとき、一対の係止片６のそれぞれの自由端が前記皿状部４の凹部８に収容される。   For example, when the wire harness with clip 1 formed by the mold 21 is routed across the back door and the passenger compartment, the wire 3 and the main body 5 are connected to each other as shown in FIG. If it penetrates into the attachment hole 13 of the inner panel 12 of a door, each free end of a pair of locking piece 6 will be elastically deformed in the direction which mutually adjoins. At this time, the respective free ends of the pair of locking pieces 6 are accommodated in the recesses 8 of the dish-like portion 4.

次いで、一対の係止片６が前記取付孔１３を挿通すると、前記係止片６のそれぞれの自由端が弾性回復力によって、互いに離間する方向に変位される。そして、図６に示すように、皿状部４の周縁部が前記インナーパネル１２に当接し、一対の係止片６のそれぞれの自由端が前記取付孔１３の内周面に係止されると共に、前記係止片６のそれぞれの自由端が前記取付孔１３の周縁部に係止される。   Next, when the pair of locking pieces 6 are inserted through the mounting holes 13, the respective free ends of the locking pieces 6 are displaced in directions away from each other by the elastic recovery force. As shown in FIG. 6, the peripheral edge of the dish-like portion 4 abuts on the inner panel 12, and the free ends of the pair of locking pieces 6 are locked to the inner peripheral surface of the mounting hole 13. At the same time, each free end of the locking piece 6 is locked to the peripheral edge of the mounting hole 13.

このため、上述のクリップ付ワイヤハーネス１は、前記皿状部４が前記パネル１２に当接した状態において、前記係止片６のそれぞれの自由端が前記取付孔１３の周縁部に係止すると共に、前記それぞれの自由端が前記取付孔１３の内周面に係止するため、前記電線３の長手方向に対して前記クリップ２のガタツキが防止され、かつ、クリップ２と前記取付孔１３とが確実に係止される。   For this reason, in the wire harness with clip 1 described above, each free end of the locking piece 6 is locked to the peripheral edge of the mounting hole 13 in a state where the dish-shaped portion 4 is in contact with the panel 12. At the same time, since the respective free ends are locked to the inner peripheral surface of the mounting hole 13, rattling of the clip 2 with respect to the longitudinal direction of the electric wire 3 is prevented, and the clip 2 and the mounting hole 13 Is securely locked.

上述の一実施形態にかかるクリップ付ワイヤハーネス１は、パネル１２の取付孔１３に係止されるクリップ２が電線３に一体成形されている。前記クリップ２は、前記取付孔１３に重ねられると共に前記パネル１２に当接される皿状部４と、前記皿状部４から立設され前記取付孔１３に挿通される本体部５と、前記取付孔１３の周縁部に係止される係止片６と、を備え、前記電線３が、前記皿状部４と前記本体部５とを貫通して設けられている。さらに、前記皿状部４には、前記係止片６の自由端が収容される凹部８が設けられている。   In the wire harness with clip 1 according to the above-described embodiment, the clip 2 that is locked to the mounting hole 13 of the panel 12 is integrally formed with the electric wire 3. The clip 2 is overlapped with the mounting hole 13 and abutted against the panel 12, the main body 5 erected from the dish-shaped portion 4 and inserted into the mounting hole 13, A locking piece 6 that is locked to the peripheral edge of the mounting hole 13, and the electric wire 3 is provided through the dish-like portion 4 and the main body portion 5. Further, the dish-like portion 4 is provided with a recess 8 in which the free end of the locking piece 6 is accommodated.

このため、本発明にかかるクリップ付ワイヤハーネス１は、パネル１２の取付孔１３にクリップ２を挿通させるだけで、前記クリップ付ワイヤハーネス１が前記取付孔１３に係止される。このため、クリップ付ワイヤハーネス１は、従来のグロメットを有するワイヤハーネスよりも容易かつ迅速に、パネル１２の取付孔１３に取り付けることができる。   For this reason, in the wire harness with clip 1 according to the present invention, the wire harness with clip 1 is locked to the attachment hole 13 only by inserting the clip 2 into the attachment hole 13 of the panel 12. For this reason, the wire harness 1 with a clip can be attached to the attachment hole 13 of the panel 12 more easily and more quickly than a wire harness having a conventional grommet.

また、クリップ付ワイヤハーネス１は、前記皿状部４と前記パネル１２とが当接した状態において、前記係止片６の自由端が前記皿状部４に接触することなく、前記取付孔１３内に深く侵入できるため、前記係止片６の前記自由端が前記取付孔１３の周縁部と内周面とに係止する。従って、クリップ付ワイヤハーネス１は、前記クリップ２が前記電線３の長手方向にガタつくことが防止され、かつ、前記クリップ２が前記取付孔１３に確実に係止される。   In addition, the clip-attached wire harness 1 is configured so that the free end of the locking piece 6 does not contact the dish-like part 4 in a state where the dish-like part 4 and the panel 12 are in contact with each other. Since it can penetrate | invade deeply, the said free end of the said locking piece 6 latches to the peripheral part of the said attachment hole 13, and an internal peripheral surface. Therefore, in the wire harness with clip 1, the clip 2 is prevented from rattling in the longitudinal direction of the electric wire 3, and the clip 2 is reliably locked in the mounting hole 13.

また、クリップ付ワイヤハーネス１は、電線３にクリップ２が一体成形されて形成されているため、前記クリップ２の組立工程、前記クリップ２を前記電線３に組み付ける工程などが省略される。このため、クリップ付ワイヤハーネス１の製造工程が短縮され、製造にかかる所要時間が短縮される。   In addition, since the clip-attached wire harness 1 is formed by integrally forming the clip 2 on the electric wire 3, the assembly process of the clip 2, the process of assembling the clip 2 to the electric wire 3, and the like are omitted. For this reason, the manufacturing process of the wire harness 1 with a clip is shortened, and the time required for manufacture is shortened.

また、クリップ付ワイヤハーネス１は、止水機能が不要なバックドアのインナーパネル１２等に好適に使用することができる。   Moreover, the wire harness 1 with a clip can be used suitably for the inner panel 12 of the back door etc. which do not require a water stop function.

なお、前述した実施形態は本発明の代表的な形態を示したに過ぎず、本発明は、実施形態および変形例に限定されるものではない。即ち、本発明の骨子を逸脱しない範囲で種々変形して実施することができる。   In addition, embodiment mentioned above only showed the typical form of this invention, and this invention is not limited to embodiment and a modification. That is, various modifications can be made without departing from the scope of the present invention.
