Description

本発明は、自動車や電車などの車両内に配索されるワイヤハーネスや、自動ドアのような可動装置に使用される電線の余分な余長部を吸収する余長吸収装置に関するものである。   The present invention relates to a surplus length absorbing device that absorbs an extra surplus length portion of an electric wire used in a movable device such as a wire harness or an automatic door arranged in a vehicle such as an automobile or a train.

自動車内にワイヤハーネスを配索する際や自動ドアなどの可動部を持つ装置に配線する際、メーターなどの部品の組み付けに必要な長さ及びドアやステアリングコラムなどの可動箇所における各動作の追随に必要な長さを余長として見積り、その電線やワイヤハーネスの長さを決定するが、完成後、その余長部分の電線やワイヤハーネスが、捩れたり、可動箇所に挟まったりして、傷つけてしまい、断線などの故障原因となる恐れがあった。   When wiring a wire harness in an automobile or wiring to a device with a moving part such as an automatic door, the length required to assemble parts such as a meter and the movement of each part in a movable part such as a door or steering column Estimate the length necessary for the extra length and determine the length of the electric wire or wire harness.After completion, the extra length portion of the electric wire or wire harness may be twisted or pinched in a movable part, resulting in damage. There is a risk of failure such as disconnection.

そこで、このような余長を吸収する様々な構造が提案されている（特許文献１及び特許文献２参照）。
特許文献１では、アーチ形状ハーネス保持弾性板でワイヤハーネスを拘束し、常態時ではアーチ形状を保つことで余長を吸収し、ステアリングコラムが可動したときに、ワイヤハーネスが引き出される状態になり、アーチ形状ハーネス保持弾性板も拡張され、蓄えた余長が繰り出され、ステアリングコラムが元の位置に戻るときに、アーチ形状ハーネス保持弾性板の弾性によりアーチ形状に復帰して余長を吸収する。 Therefore, various structures that absorb such extra length have been proposed (see Patent Document 1 and Patent Document 2).
In Patent Document 1, the wire harness is restrained by the arch-shaped harness holding elastic plate, and the extra length is absorbed by maintaining the arch shape in the normal state, and when the steering column moves, the wire harness is pulled out, The arch-shaped harness holding elastic plate is also expanded, and the stored surplus length is paid out, and when the steering column returns to the original position, it is restored to the arch shape by the elasticity of the arch-shaped harness holding elastic plate and absorbs the surplus length.

特許文献２では、先端で連結された一対のハーネス支持脚の各基端部および先端連結部の３点でワイヤハーネスを支持し、そのハーネス支持脚基端部の間隔を拡縮することで、ワイヤハーネスの余長を吸収する。   In Patent Document 2, a wire harness is supported at three points, that is, a base end portion and a tip connection portion of a pair of harness support legs connected at the distal end, and the interval between the harness support leg proximal end portions is expanded and contracted. Absorb the extra length of the harness.

特開２００３−３２８６８号公報Japanese Patent Laid-Open No. 2003-32868 特開２００３−３２８６９号公報Japanese Patent Laid-Open No. 2003-32869

しかしながら、特許文献１及び特許文献２で提案されるワイヤハーネス余長吸収装置では、ステアリングコラムなどの可動部分が動作するのに必要なワイヤハーネスの余長を規則性をもって円滑に伸縮動作させる働きを有するが、メーターなどの固定部品を車体に組み付けるときに必要な余長を吸収する働きは有していない。
更に、特許文献２で提案されているワイヤハーネス余長吸収装置では、ハーネス支持脚の一端側を外力に応じて滑らせるためのガイド溝、ガイドプレートおよびスライダ片などを備えなくてはならず、更に、ワイヤハーネスの収縮動作をより円滑にするための弾性部材も備えられている。従って、その構成部品数が多くなり、ワイヤハーネス吸収装置としては、その重量増加および設置スペースの増大が問題となってくる。 However, in the wire harness surplus length absorption device proposed in Patent Document 1 and Patent Document 2, the surplus length of the wire harness necessary for the operation of the movable part such as the steering column is smoothly expanded and contracted with regularity. However, it does not have the function of absorbing the extra length required when a fixed part such as a meter is assembled to the vehicle body.
Furthermore, in the wire harness surplus length absorbing device proposed in Patent Document 2, it is necessary to provide a guide groove, a guide plate, a slider piece, and the like for sliding one end side of the harness support leg according to an external force, Furthermore, the elastic member for making contraction operation | movement of a wire harness smoother is also provided. Therefore, the number of components increases, and as a wire harness absorber, an increase in weight and an increase in installation space become a problem.

本願は、このような状況に鑑み、種々の検討を踏まえて成したもので、本発明の目的は、ステアリング装置の調整機構やドアの開閉動作などにおけるワイヤハーネスや電線の余長吸収のみならず、電線やワイヤハーネスの組み付け時に必要であった余長分を吸収することができ、且つ部品点数の少ないコンパクトな余長吸収装置を提供するものである。   In view of such circumstances, the present application has been made based on various studies, and the object of the present invention is not only to absorb the extra length of a wire harness or an electric wire in an adjustment mechanism of a steering device or an opening / closing operation of a door. The present invention provides a compact surplus length absorbing device that can absorb the surplus length required when assembling an electric wire or a wire harness and has a small number of parts.

本発明の実施形態となる余長吸収装置１について図面を参照しながら説明する。
図１は、本発明の第一実施形態に係る余長吸収装置１の支持体２とバネ弾性部材４を示しており、（イ）は全体図、（ロ）は分割体２ａ（もしくは２ｂ）の平面図、（ハ）は（ロ）における曲げ部３の拡大図である。
図２は、余長吸収装置１の全体を電線１０を組み付けた状態で示しており、（イ）は電線１０が引っ張られていない状態を示し、（ロ）は電線１０が引っ張られたときの状態を示す。 The surplus length absorber 1 which becomes embodiment of this invention is demonstrated referring drawings.
FIG. 1 shows a support body 2 and a spring elastic member 4 of a surplus length absorbing device 1 according to the first embodiment of the present invention, where (A) is an overall view and (B) is a divided body 2a (or 2b). (C) is the enlarged view of the bending part 3 in (b).
FIG. 2 shows the entire surplus length absorbing device 1 in a state where the electric wire 10 is assembled, (A) shows a state where the electric wire 10 is not pulled, and (B) shows a state where the electric wire 10 is pulled. Indicates the state.

図１（イ）、（ロ）、および図２（イ）、（ロ）に示すように、本実施形態の余長吸収装置１は、電線１０を保持し、かつ自身が変形することで電線１０の余長を吸収するものであり、支持体２と、バネ弾性部材４と、クランプ８とを有する。   As shown in FIGS. 1 (a), (b), and FIGS. 2 (a), 2 (b), the extra length absorber 1 of the present embodiment holds the electric wire 10 and deforms itself by deforming itself. It absorbs the extra length of 10, and includes a support body 2, a spring elastic member 4, and a clamp 8.

支持体２は、曲げ部３と、該曲げ部３の両端部からそれぞれ該曲げ部３の長手方向に対して垂直な同方向に延出された２つの脚部１３ａ、１３ｂとを有し、全体として図１（ロ）に示す略門型形状を有する。   The support body 2 has a bent portion 3 and two leg portions 13a and 13b extending in the same direction perpendicular to the longitudinal direction of the bent portion 3 from both ends of the bent portion 3, respectively. As a whole, it has a substantially portal shape shown in FIG.

曲げ部３は、例えばここでは、左右両方の曲げ部３本体が２つのヒンジ３ａ、３ｂで連結してなる構造とされており、曲げ部３が外力を受けない状態では、図１（イ）〜（ハ）、図２（イ）に示すように、長手方向に一直線状になるよう構成されている。
脚部１３ａ、１３ｂにはそれぞれ後述のクランプ８を取り付けるためのクランプ取り付け穴７が適宜の間隔で、複数、貫通形成されている。ここでは、図２（イ）、（ロ）に示すように、支持体２の外表面に沿って電線１０を組み付けることになるため、図１（ロ）に示すように、支持体２の外表面側から内表面側に向けてクランプ取り付け穴７が貫通形成されている。 Here, for example, the bent portion 3 has a structure in which the left and right bent portion 3 main bodies are connected by two hinges 3a and 3b. In the state where the bent portion 3 is not subjected to external force, FIG. -(C), as shown in FIG. 2 (a), it is configured to be linear in the longitudinal direction.
A plurality of clamp mounting holes 7 for mounting clamps 8 to be described later are formed through the leg portions 13a and 13b at appropriate intervals. Here, since the electric wires 10 are assembled along the outer surface of the support 2 as shown in FIGS. 2 (a) and 2 (b), the outside of the support 2 as shown in FIG. 1 (b). A clamp attachment hole 7 is formed through from the surface side toward the inner surface side.

ここで支持体２は、図１（ロ）に示すような２つの分割体２ａ、２ｂを、図１（イ）に示すように組み合わせてなるものである。図１（ロ）に示すように、２つの分割体２ａ、２ｂはそれぞれ適宜、支持体組み付けピン６ａと支持体組み付け穴６ｂを有しており、これらが組み合わさることで分割体２ａ、２ｂが互いに固定され、１つの支持体２が形成される。なお分割体２ａ、２ｂを組み合わせた際に曲げ部３内部には、図１（ロ）に示すように、左右２つの収容空間３ｃ、３ｃが出来る。
この支持体２は、ヒンジ３a、３ｂが曲げ変形可能な薄板構造であるため、図２（ロ）に示すように脚部１３ａ、１３ｂの先端同士の間隔を広げるように、曲げ変形することが可能である。 Here, the support 2 is formed by combining two divided bodies 2a and 2b as shown in FIG. 1 (b) as shown in FIG. 1 (a). As shown in FIG. 1 (b), each of the two divided bodies 2a and 2b has a support assembly pin 6a and a support assembly hole 6b as appropriate. One support body 2 is formed by being fixed to each other. In addition, when the divided bodies 2a and 2b are combined, two left and right accommodation spaces 3c and 3c are formed inside the bent portion 3 as shown in FIG.
Since the support 2 has a thin plate structure in which the hinges 3a and 3b can be bent and deformed, the support 2 can be bent and deformed so as to widen the distance between the ends of the leg portions 13a and 13b as shown in FIG. Is possible.

バネ弾性部材４は平板状の形状を有する、いわゆる板バネ（材質は例えばバネ鋼）であり、上述の２つの収容空間３ｃ、３ｃにまたがってほぼ隙間無く挿入保持されている。バネ弾性部材４は、荷重負荷のない状態では、図１（ロ）に示すように、曲げ部３の長手方向に向かって平面視、略一直線状となる状態を維持するが、前述のように曲げ部３がヒンジ３ａ、３ｂにおいて脚部１３ａ、１３ｂの先端同士の間隔を広げる方向に曲げ変形されると、それに従って変形可能である（図２（ロ）参照）。ただしその場合には、板バネの弾性力により、図１（ロ）に示すように、支持体２の形状を図１（ロ）に示す元の状態に戻そうとする付勢力が働く。
なお支持体２の収容空間３ｃに形成された仕切り板５は、後述のバネ弾性部材４を圧入するための仕切りとして設けられており、バネ弾性部材４の脱落防止の役目を果たす。 The spring elastic member 4 is a so-called plate spring (made of spring steel, for example) having a flat plate shape, and is inserted and held across the above-described two housing spaces 3c and 3c with almost no gap. As shown in FIG. 1 (b), the spring elastic member 4 maintains a substantially straight state in a plan view toward the longitudinal direction of the bending portion 3 in a state where no load is applied. When the bending portion 3 is bent and deformed in the direction in which the distance between the tips of the leg portions 13a and 13b is increased at the hinges 3a and 3b, the bending portion 3 can be deformed accordingly (see FIG. 2B). In this case, however, the elastic force of the leaf spring causes a biasing force to return the shape of the support 2 to the original state shown in FIG. 1 (B) as shown in FIG.
In addition, the partition plate 5 formed in the accommodation space 3c of the support body 2 is provided as a partition for press-fitting a spring elastic member 4 described later, and serves to prevent the spring elastic member 4 from falling off.

図５は、クランプ８を示す斜視図である。
図５に示すように、クランプ８は、いわゆるバンドクランプで、バンド部８ａと、該バンド部８ａの一部に突設形成されたアンカー部８ｂとを有しており、支持体２への組み付け前に電線１０にバンド部８ａによって締結されている。このクランプ８と支持体２のクランプ取り付け穴７とは一対の電線保持機構を形成している。すなわち、図２（イ）、（ロ）に示すように、支持体２上に適宜設けられたクランプ取り付け穴７にアンカー部８ｂを圧入固定することで、クランプ８が支持体２上に固定され、これにより支持体２の略門型形状に沿って電線１０を保持することができる。 FIG. 5 is a perspective view showing the clamp 8.
As shown in FIG. 5, the clamp 8 is a so-called band clamp, and includes a band portion 8 a and an anchor portion 8 b formed to project from a part of the band portion 8 a, and is attached to the support body 2. It is fastened to the electric wire 10 by the band portion 8a before. The clamp 8 and the clamp mounting hole 7 of the support 2 form a pair of electric wire holding mechanisms. That is, as shown in FIGS. 2A and 2B, the clamp 8 is fixed on the support 2 by press-fitting and fixing the anchor portion 8b into the clamp mounting hole 7 appropriately provided on the support 2. Thereby, the electric wire 10 can be hold | maintained along the substantially gate-shaped shape of the support body 2. FIG.

上述のような余長吸収装置１においては、電線１０が引っ張られて曲げ部３が曲げ変形し、脚部１３ａ、１３ｂの先端同士の間隔が広げられている状態においては、バネ弾性部材４のバネ弾性力により、前記間隔が最小限度に規制されることで、電線１０の余長が吸収される。
すなわち電線１０が余長吸収装置１の両側で引っ張られていない状態、もしくは電線１０が余長吸収装置１の両側に引っ張られている状態であってもヒンジ３ａ、３ｂおよびバネ弾性部材４がその状態を維持しようとするバネ弾性力のほうが優勢である場合には、図２（イ）に示すように、ヒンジ３ａ、３ｂおよびバネ弾性部材４は曲げ変形せず、脚部１３ａ、１３ｂ同士は閉じたままであり、支持体２は略門型形状を維持している。 In the surplus length absorbing device 1 as described above, in the state where the electric wire 10 is pulled and the bent portion 3 is bent and deformed, and the distance between the tips of the leg portions 13a and 13b is widened, the spring elastic member 4 The extra length of the electric wire 10 is absorbed by the spring elastic force restricting the interval to the minimum.
That is, even if the electric wire 10 is not pulled on both sides of the surplus length absorbing device 1 or the electric wire 10 is pulled on both sides of the surplus length absorbing device 1, the hinges 3a and 3b and the spring elastic member 4 are When the spring elastic force to maintain the state is dominant, the hinges 3a and 3b and the spring elastic member 4 are not bent and deformed as shown in FIG. It remains closed and the support body 2 maintains a substantially portal shape.

これに対して、電線１０が余長吸収装置１の両側で引っ張られている状態において、ヒンジ３ａ、３ｂおよびバネ弾性部材４がその状態を維持しようとするバネ弾性力よりも電線１０が引っ張られる力が優勢となった場合には、図２（ロ）に示すように、ヒンジ３ａ、３ｂおよびバネ弾性部材４が曲げ変形する。よって支持体２全体としては、脚部１３ａ、１３ｂの先端同士の間隔を広げるように、曲げ部３において屈曲変形する（脚部１３ａ、１３ｂ同士の開き角をθとする）。   On the other hand, in the state where the electric wire 10 is pulled on both sides of the surplus length absorber 1, the electric wire 10 is pulled more than the spring elastic force that the hinges 3a, 3b and the spring elastic member 4 try to maintain that state. When the force becomes dominant, the hinges 3a and 3b and the spring elastic member 4 are bent and deformed as shown in FIG. Therefore, the support 2 as a whole is bent and deformed at the bending portion 3 so as to widen the distance between the ends of the leg portions 13a and 13b (the opening angle between the leg portions 13a and 13b is θ).

このような場合も、ヒンジ３ａ、３ｂおよびバネ弾性部材４は図２（イ）のような荷重負荷の無い状態に戻ろうとするバネ弾性力は働いているため、電線１０が引っ張られる力が弱くなれば、その分、ヒンジ３ａ、３ｂおよびバネ弾性部材４のバネ弾性力が優勢になるので、脚部１３ａ，１３ｂの先端同士の間隔が狭くなり、開き角θが小さくなって、開き角θがゼロ、すなわち図２（イ）の状態に戻るまで、電線１０の余長は余長吸収装置１に吸収されることになる。
このように余長吸収装置１は、電線１０の引っ張り力の強弱に応じて、電線１０の余長を吸収することができる。 Also in such a case, since the springs 3a and 3b and the spring elastic member 4 have a spring elastic force that tries to return to a state without a load load as shown in FIG. 2 (a), the force with which the electric wire 10 is pulled is weak. If so, the spring elastic force of the hinges 3a, 3b and the spring elastic member 4 becomes dominant, so that the distance between the tips of the leg portions 13a, 13b is reduced, the opening angle θ is reduced, and the opening angle θ is reduced. 2 is zero, that is, the surplus length of the electric wire 10 is absorbed by the surplus length absorber 1 until it returns to the state of FIG.
Thus, the surplus length absorbing device 1 can absorb the surplus length of the electric wire 10 according to the strength of the pulling force of the electric wire 10.

このような本実施形態の余長吸収装置１の実用例について図３、図４を参照して説明する。
図３（イ）〜（ハ）は、電線１０の先端の補器１１を取り付け部位１２に取り付ける作業手順を示す側面図であり、図４（イ）〜（ハ）はそのそれぞれに対応する余長吸収装置１の状態を示す拡大側面図である。
まず図３（イ）に示すように、電線１０の先端に補器１１が取り付けられるとともに、電線１０の途中に余長吸収装置１が固定される。このとき電線１０は余長吸収装置1の両端において引っ張られておらず、図４（イ）に示すように、余長吸収装置１の支持体２は略門型形状を維持している。 A practical example of the surplus length absorber 1 of this embodiment will be described with reference to FIGS.
3 (a) to 3 (c) are side views showing a work procedure for attaching the auxiliary device 11 at the tip of the electric wire 10 to the attachment site 12, and FIGS. 4 (a) to 4 (c) are the surpluses corresponding to each. It is an enlarged side view which shows the state of the long absorption apparatus.
First, as shown in FIG. 3A, the auxiliary device 11 is attached to the tip of the electric wire 10, and the surplus length absorber 1 is fixed in the middle of the electric wire 10. At this time, the electric wire 10 is not pulled at both ends of the surplus length absorbing device 1, and the support 2 of the surplus length absorbing device 1 maintains a substantially portal shape as shown in FIG.

次に図３（ロ）に示すように、電線１０が取り付け部位１２側に引っ張られ、補器１１が取り付け部位１２に取り付けられる。このとき取り付け作業性向上のため、電線１０は補器１１近傍で余分に引っ張られ、電線１０の作業余長１０ａが形成されるため、図４（ロ）に示すように、余長吸収装置１の支持体２は、曲げ部３において大きく屈曲される。
最後に図３（ハ）に示すように、不要となった作業余長１０ａが解消されるため、その分電線１０の余長ができるが、電線１０の引っ張り力がなくなったことで、余長吸収装置１は図４（イ）の状態にできるだけ戻ろうとする。ただし、電線１０の先端は補器１１と取り付け部位１２で固定されているため、余長吸収装置１は元の状態には戻りきれず、図４（ハ）に示すような状態で安定する。 Next, as shown in FIG. 3B, the electric wire 10 is pulled toward the attachment site 12, and the auxiliary device 11 is attached to the attachment site 12. At this time, in order to improve the mounting workability, the electric wire 10 is excessively pulled in the vicinity of the auxiliary device 11 to form a working surplus length 10a of the electric wire 10, so that as shown in FIG. The support body 2 is largely bent at the bending portion 3.
Finally, as shown in FIG. 3 (c), the unnecessary work extra length 10a is eliminated, so that the extra length of the electric wire 10 can be made. However, the extra length is eliminated by eliminating the pulling force of the electric wire 10. The absorber 1 tries to return as much as possible to the state of FIG. However, since the tip of the electric wire 10 is fixed by the auxiliary device 11 and the attachment part 12, the surplus length absorbing device 1 cannot return to the original state and is stabilized in the state shown in FIG.

このように、本実施形態の余長吸収装置１によれば、電線１０の余長を適宜吸収することができる。
また本実施形態の余長吸収装置１は、上述したような構造をとるため、従来構造に比べて部品点数が少なく構成でき、かつ設置スペースの問題や重量増加の問題を解決することが出来る。
また余長吸収装置１（クランプ８を除く）を予め組み立てて準備しておけば、必要に応じて、電線１０にクランプ８を取り付けて余長吸収装置1に取り付けるだけで、非常に簡便に電線１０の余長吸収構造を構成することができる。
なお本発明の余長吸収装置は、上記実施形態に限定されるものではなく、種々の変更が可能である。
また本発明の余長吸収装置は電線1本を保持するとは限らず、複数本の電線を集合させた、いわゆるワイヤハーネスを保持するものであってもよい。 Thus, according to the surplus length absorber 1 of this embodiment, the surplus length of the electric wire 10 can be absorbed appropriately.
Moreover, since the surplus length absorbing device 1 of the present embodiment has the above-described structure, it can be configured with a smaller number of parts than the conventional structure, and can solve the problem of installation space and the problem of weight increase.
Also, if the extra length absorber 1 (except for the clamp 8) is assembled and prepared in advance, the electric wire can be very simply simply attached to the extra length absorber 1 by attaching the clamp 8 to the electric wire 10 as necessary. Ten extra length absorption structures can be constructed.
In addition, the surplus length absorber of this invention is not limited to the said embodiment, A various change is possible.
Further, the surplus length absorbing device of the present invention does not necessarily hold one electric wire but may hold a so-called wire harness in which a plurality of electric wires are assembled.
