Description
【０００１】[0001]
この考案は、自動車用フラットワイヤーハーネス等に利用されるフレキシブル プリント配線板に関する。 The present invention relates to a flexible printed wiring board used for automobile flat wire harnesses and the like.
【０００２】[0002]
自動車用ワイヤーハーネスには、並列状に配列された複数の回路から所望の回 路を途中で曲成させて側方へ引き出すような回路構造を必要とするものがある。 Some automotive wire harnesses require a circuit structure in which a desired circuit is bent in the middle of a plurality of circuits arranged in parallel and pulled out to the side.
【０００３】 このような回路構造をＦＰＣ等のフレキシブルプリント配線板により実現する 場合、一般的には図４に示すように、帯状のフィルムＦ上に上記回路パターンに 対応する回路導体１〜４を印刷し、さらにその上面に他の帯状フィルムＦを被覆 してから、同図想像線に示す不要部分５を除去することにより行われる。When such a circuit structure is realized by a flexible printed wiring board such as an FPC, generally, as shown in FIG. 4, circuit conductors 1 to 4 corresponding to the above circuit pattern are formed on a strip-shaped film F. The printing is performed, the upper surface thereof is covered with another strip-shaped film F, and then the unnecessary portion 5 shown by the imaginary line in the figure is removed.
【０００４】 一方近年になって、所望の回路導体部分を折り返すことにより側方へ引き出す 技術が提案されている。例えば図５に示すように、並列状に配列された４本の回 路導体１１〜１４のうち所望の回路導体１４と、その隣りの回路導体１３との間 の非配線領域に、回路導体１１〜１４の長手方向に沿ってフレキシブルプリント 配線板２０の端部から所定量だけ切込部１５を形成して、これにより所望の回路 導体１４の途中から端部までの領域を含む枝条領域１４ａを形成しておく。On the other hand, in recent years, a technique has been proposed in which a desired circuit conductor portion is folded back and pulled out to the side. For example, as shown in FIG. 5, the circuit conductor 11 is provided in a non-wiring region between a desired circuit conductor 14 of the four circuit conductors 11 to 14 arranged in parallel and the adjacent circuit conductor 13. The cut portions 15 are formed from the ends of the flexible printed wiring board 20 by a predetermined amount along the longitudinal direction of 14 to 14 so that the branch region 14a including the region from the middle to the end of the desired circuit conductor 14 is formed. Form.
【０００５】 そして実使用状態では図６に示すように、枝条領域１４ａを側方に折り返し、 これにより回路導体１４を途中で曲成して側方へ引き出す。In the actual use state, as shown in FIG. 6, the branch area 14a is folded back to the side, whereby the circuit conductor 14 is bent halfway and pulled out to the side.
【０００６】[0006]
しかしながら、図４に示すフレキシブルプリント配線板１０では、回路導体４ が枝分れするように形成されているため、枝分れ領域４ａの周辺に同図想像線に 示すように不要のフィルム部分５が多く発生し、材料ロスを生じるという問題が ある。また、枝分れ領域４ａは幅が狭く線状に延びているため、フレキシブルプ リント配線板１０を多数重ね合せて搬送する場合、搬送中に枝分れ領域４ａがば らけて絡み付くおそれがあり、搬送作業を慎重に行う必要があった。 However, in the flexible printed wiring board 10 shown in FIG. 4, since the circuit conductor 4 is formed so as to branch, the unnecessary film portion 5 is formed around the branch region 4a as shown by the imaginary line in FIG. However, there is a problem that many materials are generated, resulting in material loss. Further, since the branched region 4a has a narrow width and extends linearly, when a plurality of flexible printed wiring boards 10 are stacked and conveyed, the branched region 4a may be entangled by being scattered during the conveyance. Yes, it was necessary to carry out the transportation work carefully.
【０００７】 一方、図５に示すフレキシブルプリント配線板２０では、各回路導体１１〜１ ４が並列状に配列されるため、回路導体１１〜１４を帯状領域内に治まりよく配 置できて材料ロスを低減できるものの、枝条領域１４ａが細く線状に延びている ため、上記と同様に搬送中の取扱が繁雑であるという問題は解消できない。On the other hand, in the flexible printed wiring board 20 shown in FIG. 5, since the circuit conductors 11 to 14 are arranged in parallel, the circuit conductors 11 to 14 can be arranged well in the strip-shaped region and the material loss can be prevented. However, since the branch area 14a extends in a thin linear shape, the problem of complicated handling during transportation cannot be solved in the same manner as described above.
【０００８】 この考案は、上記従来技術の問題を解消し、搬送時の取扱が容易で、実使用時 には所望の回路導体を支障なく側方に引き出すことができ、しかも材料ロスを低 減できるフレキシブルプリント配線板を提供することを目的とする。This invention solves the above-mentioned problems of the prior art, is easy to handle during transportation, and allows the desired circuit conductor to be pulled out to the side without any hindrance during actual use, and also reduces material loss. An object of the present invention is to provide a flexible printed wiring board that can be used.
【０００９】[0009]
この考案は、並列状に配列された複数の回路導体がフィルムにより被覆され、 実使用状態では前記複数の回路導体のうち所望の回路導体とその隣の回路導体と の間の非配線領域を前記回路導体の長手方向に沿って配線板端部から途中位置ま で切り裂いて前記所望の回路導体を含む枝条領域を形成するとともに、その枝条 領域を側方へ折り返すことにより、前記所望の回路導体を途中で曲成させて側方 に引き出すようにしたフレキシブルプリント配線板であって、上記目的を達成す るため、前記非配線領域の切裂予定位置に沿って複数の切裂ガイド用孔を間欠的 に形成している。 In this invention, a plurality of circuit conductors arranged in parallel are covered with a film, and in a practical use state, a non-wiring region between a desired circuit conductor and a circuit conductor adjacent to the desired circuit conductor is The desired circuit conductor is formed by cutting along the longitudinal direction of the circuit conductor from the end of the wiring board to an intermediate position to form a branch area containing the desired circuit conductor and folding the branch area sideways. In order to achieve the above object, the flexible printed wiring board is bent in the middle and pulled out to the side, and in order to achieve the above object, a plurality of tear guide holes are intermittently provided along the planned tear positions in the non-wiring area. It is being formed
【００１０】[0010]
この考案のフレキシブルプリント配線板によれば、切裂ガイド用孔に沿って切 り裂く前の状態では枝状領域が存在しないため、その状態でフレキシブルプリン ト配線板を搬送することにより、搬送作業が容易になる。また、実使用時には複 数の切裂ガイド用孔に沿って非配線領域を切り裂くだけで枝条領域を形成でき、 その枝条領域を折り返すことにより支障なく所望の回路導体を側方へ引き出すこ とができる。しかも、複数の回路導体を並列状に配列した状態でフレキシブルプ リント配線板を形成できるため、材料ロスを低減できる。 According to the flexible printed wiring board of the present invention, since there is no branch area before the slit is cut along the slit guide hole, the flexible printed wiring board is transported in that state, so that the transfer work can be performed. Will be easier. Also, in actual use, a branch area can be formed simply by cutting the non-wiring area along the multiple tear guide holes, and by folding back the branch area, the desired circuit conductor can be pulled out to the side without hindrance. it can. Moreover, since the flexible printed wiring board can be formed with a plurality of circuit conductors arranged in parallel, material loss can be reduced.
【００１１】[0011]
図１はこの考案の一実施例であるフレキシブルプリント配線板３０を示す平面 図である。同図に示すように、このフレキシブルプリント配線板３０は、帯状の フィルムＦ上に４本の回路導体２１〜２４を並列状に印刷し、その上から他の帯 状フィルムＦを貼り合わすように被覆して形成される。この場合、フレキシブル プリント配線板３０の一端において、回路導体２１〜２３を含む領域の一部が除 去され、その領域の端部位置が回路導体２４を含む領域の端部位置よりも後退す るように形成される。また、回路導体２４とその隣に配置される回路導体２３と の間の非配線領域には、回路導体２１〜２４の長手方向に沿って配線板３０の端 部位置から途中位置（回路導体２４を曲成させる位置）まで間欠的に複数の切裂 ガイド用スリット２５が形成される。 FIG. 1 is a plan view showing a flexible printed wiring board 30 which is an embodiment of the present invention. As shown in the figure, in this flexible printed wiring board 30, four circuit conductors 21 to 24 are printed in parallel on a strip-shaped film F, and another strip-shaped film F is laminated on the printed circuit conductors 21 to 24. It is formed by coating. In this case, a part of the region including the circuit conductors 21 to 23 is removed at one end of the flexible printed wiring board 30, and the end position of the region is set back from the end position of the region including the circuit conductor 24. Is formed as. In the non-wiring region between the circuit conductor 24 and the circuit conductor 23 arranged next to the circuit conductor 24, an intermediate position (circuit conductor 24) along the longitudinal direction of the circuit conductors 21 to 24 is formed. A plurality of slit guide slits 25 are intermittently formed up to the position (bending position).
【００１２】 このフレキシブルプリント配線板２０において、実使用する場合には必要に応 じてコネクタ等を取り付けてから、図２に示すようにスリット２５に沿って非配 線領域を切り裂いて、回路導体２４の途中から端部までの領域を含む枝条領域２ ４ａを形成する。In this flexible printed wiring board 20, when actually used, a connector or the like is attached as needed, and then the non-wiring region is cut along the slit 25 as shown in FIG. The branch region 24a including the region from the middle of 24 to the end is formed.
【００１３】 つづいて図３に示すように、枝条領域２４ａを側方に折り返し、これにより回 路導体２４を途中で曲成させて側方に引き出す。なお、コネクタの取り付けは、 スリット２５に沿って非配線領域を切り裂いた後に行ってもよい。Subsequently, as shown in FIG. 3, the branch region 24a is folded back to the side, whereby the circuit conductor 24 is bent halfway and pulled out to the side. The connector may be attached after cutting the non-wiring region along the slit 25.
【００１４】 このフレキシブルプリント配線板３０によれば、曲成すべき所望の回路導体２ ４とその隣の回路導体２３との間の非配線領域に間欠的に切裂ガイド用スリット ２５を形成するだけにとどめているため、この状態では図４および図５の従来例 に示すような枝分れ領域４ａおよび枝条領域１４ａ等の枝状の領域は存在しない 。したがってこの状態のまま、フレキシブルプリント配線板３０を多数重ね合わ せて搬送すれば、一部の領域がばらけることはなく絡み付きが防止されるので、 搬送作業が容易になる。According to the flexible printed wiring board 30, only the slit guide slits 25 are intermittently formed in the non-wiring region between the desired circuit conductor 24 to be bent and the adjacent circuit conductor 23. Therefore, in this state, there are no branched regions such as the branched region 4a and the branch region 14a as shown in the conventional example of FIGS. 4 and 5. Therefore, in this state, if a large number of flexible printed wiring boards 30 are superposed and conveyed, part of the area is not scattered and entanglement is prevented, so that the conveyance work is facilitated.
【００１５】 また、曲成すべき所望の回路導体２４とその隣の回路導体２３との間の非配線 領域に間欠的に切裂ガイド用スリット２５を形成しているため、実使用時にはス リット２５に沿って非配線領域を引き裂くだけで、簡単に所望の回路導体２４を 含む枝条領域２４ａを形成でき、その枝条領域２４ａを折り返すことにより支障 なく所望の回路導体２４を側方へ引き出すことができる。Further, since the slit 25 for the tear guide is intermittently formed in the non-wiring region between the desired circuit conductor 24 to be bent and the circuit conductor 23 adjacent thereto, the slit 25 is used in actual use. The branch area 24a containing the desired circuit conductor 24 can be easily formed simply by tearing the non-wiring area along, and the desired circuit conductor 24 can be pulled out to the side without trouble by folding back the branch area 24a. ..
【００１６】 しかも、各回路導体２１〜２４を並列状に配列した状態で印刷してフレキシブ ルプリント配線板３０を形成できるため、非配線領域の不要部分も少なくでき材 料ロスを低減できる。Moreover, since the flexible printed wiring board 30 can be formed by printing the circuit conductors 21 to 24 arranged in parallel, the unnecessary portion of the non-wiring region can be reduced and the material loss can be reduced.
【００１７】 なお、上記実施例では、非配線領域に間欠的にスリット２５を形成しているが 、長円形の孔や、真円形の孔を間欠的に形成してもよい。要は、非配線領域を簡 単に切り離すことができる程度に間欠的に切裂ガイド用孔が形成されていればよ い。Although the slits 25 are formed intermittently in the non-wiring region in the above embodiment, elliptical holes or true circular holes may be formed intermittently. In short, it suffices if the cut guide holes are formed intermittently to the extent that the non-wiring region can be easily separated.
【００１８】 また、上記実施例では、フレキシブルプリント配線板３０の最も外側に配置さ れた回路導体２４を側方に引き出す場合について説明したが、中央に配置される 回路導体２２または２３を側方に引き出すようにしてもよい。その場合には、そ の中央の回路導体２２または２３の両側の非配線領域にそれぞれ間欠的に切裂ガ イド用孔を形成しておいて、実使用時には上記切裂ガイド用孔に沿って回路導体 ２２または２３両側の非配線領域をそれぞれ切り裂いて回路導体２２または２３ を含む枝条領域を形成し、その領域を側方に折り返すようにすればよい。Further, in the above embodiment, the case where the circuit conductor 24 arranged on the outermost side of the flexible printed wiring board 30 is drawn out to the side has been described. However, the circuit conductor 22 or 23 arranged in the center is drawn to the side. It may be pulled out. In that case, holes for cutting guides are intermittently formed in the non-wiring regions on both sides of the circuit conductor 22 or 23 in the center, respectively, and along the holes for guiding guides during actual use. The non-wiring regions on both sides of the circuit conductor 22 or 23 may be cut to form a branch region including the circuit conductor 22 or 23, and the region may be folded back to the side.
【００１９】 また、回路導体の全体の数および側方に引き出される数が上記実施例だけに限 定されないことはいうまでもない。Needless to say, the total number of circuit conductors and the number of circuit conductors drawn out to the side are not limited to those in the above embodiment.
【００２０】[0020]
以上のように、この考案のフレキシブルプリント配線板によれば、曲成すべき 所望の回路導体とその隣の回路導体との間の非配線領域に間欠的に複数の切裂ガ イド用孔を形成しているため、切裂ガイド用孔に沿って切り裂く前の状態でフレ キシブルプリント配線板を搬送することにより、搬送作業を容易に行える。また 、実使用時には切裂ガイド用孔に沿って非配線領域を切り裂くだけで、簡単に所 望の回路導体を含む枝条領域を形成でき、その枝条領域を折り返すことにより支 障なく所望の回路導体を側方へ引き出すことができる。しかも、複数の回路導体 を並列状に配列した状態でフレキシブルプリント配線板を形成できるため、材料 ロスを低減できるという効果が得られる。 As described above, according to the flexible printed wiring board of the present invention, a plurality of cut guide holes are intermittently formed in the non-wiring region between the desired circuit conductor to be bent and the adjacent circuit conductor. Therefore, by carrying the flexible printed wiring board in a state before being torn along the tear guide hole, the carrying work can be easily carried out. Also, in actual use, the branch area containing the desired circuit conductor can be easily formed simply by cutting the non-wiring area along the cut guide hole, and by folding back the branch area, the desired circuit conductor can be easily Can be pulled out to the side. Moreover, since the flexible printed wiring board can be formed with a plurality of circuit conductors arranged in parallel, the effect of reducing material loss can be obtained.
