Description

【０００１】
【発明の属する技術分野】
本発明は、光配線板装置に関し、より詳細には、光素子や光部品、光回路基板、光回路装置等の光回路を用いた高速の通信装置や情報処理装置に用いられる光配線板装置に関する。
【０００２】
【従来の技術】
近年、通信装置の高性能化に伴い、信号伝送路として光ファイバを用いた光ファイバコードが多用されている。しかしながら、多数の光ファイバコードを装置の前面又は背面に接続する際、光ファイバコードの束が大きな空間を占め、収容性の問題や誤接続の問題などが起きているのが現状である。これらの問題を解決するために、光配線板が用いられるようになってきている（例えば、特許文献１参照）。
【０００３】
この光配線板は、粘着剤等を塗布した基材上に、任意の形状で整列された少なくとも１つの光ファイバ素線が、その上面から樹脂や可撓性のある基材で覆われる構造であり、光配線板の端部から光コネクタ等の光学接続部品（以下、光コネクタ等という）に接続するための光ファイバ素線が露出している。
【０００４】
この光ファイバ素線は、光ファイバコードと比べて光ファイバの周囲に保護材が無く、かつ大変細いために折れる恐れがあり、取扱いは慎重に行わなければいけない。また、この光配線板の端部から露出している光ファイバ素線に光コネクタ等を取り付ける際、光の損失が生じないように光コネクタ等の端面を研磨する必要がある。
【０００５】
研磨の作業を行う際には、光配線板の端部から露出している光ファイバ素線に取り付けた光コネクタ等を研磨治具に固定の上、研磨加工を行わなければならない。この場合、光配線板と光コネクタ等との間は、光ファイバ素線に対して、研磨治具の取付時や研磨加工時に細心の注意を払わなければ、光ファイバ素線は破断してしまう恐れがある。
【０００６】
また、研磨加工の終了後、装置に光配線板を取り付ける作業などを行う際にも、光配線板の端部から露出している光ファイバ素線に取り付けた光コネクタ等の着脱によって光配線板と光コネクタ等間の光ファイバ素線は破断しやすい。この部分の光ファイバ素線が破断すると光コネクタ等を取り付け直すか、また、光コネクタ等を取り付け直せるだけの光ファイバ長が残っていない場合は、この光配線板は使用できなくなる。
【０００７】
【特許文献１】
特開２００１−１４１９３６号公報
【０００８】
【発明が解決しようとする課題】
このように、光配線板の端部から露出している光ファイバ素線が破断し易いため、光配線板の歩留り低下や光配線装置への取り付け、取り外し作業における作業性の低下の問題があった。さらに、光配線装置には高い難燃性を有することを求められている。しかしながら、光配線板の本体部は、ポリイミド等の難燃性を有する基材を利用できるが、光ファイバ素線は被覆材に難燃性を有していないため、光配線板全体としては完全に高い難燃性を有することが出来ないという問題があった。
【０００９】
これらの問題を解決するため、従来、露出した光ファイバ素線に、チューブや熱収縮チューブ等を被覆させて保護を行ってきた。しかしながら、光配線板の端部とチューブや熱収縮チューブ等の端部との間に隙間ができ、前述のように、光ファイバ素線を取り扱う際に、荷重がこの隙間での光ファイバ素線に集中するため、この部分で光ファイバ素線が破断しやすいということと、また、難燃性においても光配線板の端部とチューブや熱収縮チューブ等の端部との間に隙間ができるため、高い難燃性を有することが出来ないという問題が依然として残っている。
【００１０】
本発明は、このような問題に鑑みてなされたもので、その目的とするところは、光接続部品の取り付けや研磨加工での光配線板の歩留り向上、取り外し作業における作業性の向上、作業時間の短縮及び素線破断事故の防止が出来るようにした光配線板装置を提供することにある。
【００１１】
【課題を解決するための手段】
本発明は、このような目的を達成するために、請求項１に記載の発明は、粘着剤を塗布した基材上に任意の形状で整列された少なくとも１つの光ファイバ素線を、上面から樹脂や可撓性のある基材や剛性のある基材で覆う構造を有する本体部と、該本体部より露出した光ファイバ素線を有する光配線板装置において、前記本体部から露出した光ファイバ素線を、チューブ又は熱収縮チューブで被覆保護し、かつ該チューブ又は熱収縮チューブの一端が前記本体部内に挿入されて固着されることを特徴とする。
【００１２】
また、請求項２に記載の発明は、請求項１に記載の発明において、前記本体部に切り欠き部を設け、該切り欠き部から露出した光ファイバ素線に切り欠き部内まで前記チューブ又は熱収縮チューブを挿入して被覆保護し、前記切り欠き部の上面及び下面を、該切り欠き部よりも一回り大きい可撓性のある基材や剛性のある基材で覆うことを特徴とする。
【００１３】
また、請求項３に記載の発明は、請求項１又は２に記載の発明において、前記本体部より露出している光ファイバ素線が、単心ファイバ又は多心ファイバであることを特徴とする。
【００１４】
また、請求項４に記載の発明は、請求項１，２又は３に記載の発明において、前記本体部に整列固定された光ファイバ素線が、単一モード光ファイバ又は多モード光ファイバであることを特徴とする。
【００１５】
また、請求項５に記載の発明は、請求項１乃至４いずれかに記載の発明において、前記本体部に整列固定された光ファイバ素線を被覆保護する部材に、難燃性を有するチューブ又は熱収縮チューブを用いることを特徴とする。

【発明の実施の形態】
以下、図面を参照して本発明の実施例について説明する。なお、ここに記載した実施の形態は１つの例示であって、本発明の精神を逸脱しない範囲で、種々の変更あるいは改良を行い得る事は言うまでもない。
【００１７】

【００１８】
本発明の光配線板装置は、基材７に粘着剤層８を介して光ファイバ素線２を整列固定し、その上部から可撓性のある基材や剛性のある基材によって覆われた構成である本体部１と、この本体部１の端部より露出している光ファイバ素線から構成されている。この光配線板１から露出した光ファイバ素線は、チューブ又は熱収縮チューブ３で被覆保護し、かつチューブ又は熱収縮チューブ３の一端が本体部１内に挿入されて固着されている。このように、図１に示した光配線板装置は、難燃性のチューブや熱収縮チューブ、シート等を用い、光配線板１と光接続部品４とを繋ぐ光ファイバ素線２を保護した状態を示している。
【００１９】
本発明の光配線板装置は、光配線板１に切り欠き部５を作り、そこに難燃性のチューブ又は熱収縮チューブ３等を用いて光ファイバ素線２を保護するように、チューブ又は熱収縮チューブ３等を挿入させ、切り欠き部５を覆うように、光配線板本体部１に両側からシート６等を貼りつけることで、光ファイバ素線２を保護したチューブや熱収縮チューブ３等が光配線板１内に挿入され、光配線板１と一体となるような構造となっている。
【００２０】
光配線板１と一体となるような構造をとるため、前述した光配線板１の端部とチューブ又は熱収縮チューブ３等の端部との間に隙間は出来ず、この結果、光ファイバ素線２が破断する恐れが無くなり、光配線板の歩留り向上や作業性の向上、また、難燃性のチューブ又は熱収縮チューブ等を用いることで光ファイバ部に難燃性を付与でき、信頼性の向上に繋がる。
【００２１】
図３及び図４は、本発明の光配線板装置の他の実施例を説明するための構成図で、図３は上面図、図４は図３のＢ′−Ｂ線断面図である。図中符号９は堰状物、１０は樹脂等を示している。なお、図１と同じ機能を有する構成要素については同一の符号を付してある。
【００２２】
この実施例における光配線板装置は、基材７に粘着剤層８を介して光ファイバ素線２を整列固定し、その上部からシリコーン系材料で形成された樹脂保護層１０と、この樹脂保護層１０を形成するために設けた堰状物９で構成される本体部と、この本体部より露出している光ファイバ素線２から構成されている。このように、図３に示した光配線板装置は、難燃性のチューブ又は熱収縮チューブ３等を使い、光配線板１と光接続部品類４とを繋ぐ光ファイバ素線２を保護した状態を示している。
【００２３】
この実施例の光配線板装置は、樹脂保護層１０を形成するために設けた堰状物９内に、チューブ又は熱収縮チューブ３等を用いて光ファイバ素線２を保護するように挿入させたもので、光配線板１と一体となるような構造をとるため、前述した光配線板１の端部とチューブ又は熱収縮チューブ３等の端部との間に隙間は出来ず、光ファイバ素線２が破断する恐れが無くなり、光配線板の歩留り向上や作業性の向上、また、難燃性のチューブ、熱収縮チューブ等を用いることで光ファイバ部に難燃性を付与でき、信頼性の向上に繋がる。
【００２４】
［実施例１］
図５は、本発明の光配線板装置の具体的な実施例１を示す図で、図中左の終端部１１〜１８から８芯の光ファイバ素線が８本で計６４芯の光ファイバ素線５９〜１２２が光配線板本体部内で立体交差することにより、図中右の終端部１９〜２６へと行き渡るようにシャッフルさせる機能を有する光配線板１２３を示している。
【００２５】
この光配線板本体部１２３の構造は、厚さ１２５μｍのポリイミドシート上に粘着剤を塗布して、外径２５０μｍの光ファイバ素線を布線し、再び厚さ１２５μｍのポリイミドシートで覆ったものである。この本体部１２３から露出している光ファイバ素線を被覆保護するため、光配線板本体部１２３に切り欠き部４３〜５８を入れ、光ファイバ素線を被覆保護する熱収縮チューブ２７〜４２（収縮前内径３ｍｍ）の電子線架橋軟質難燃性ポリオレフィン樹脂を挿入し、収縮させた後で切り欠き部４３〜５８を上面と下面から厚さ１２５μｍのポリイミドシートで覆った。
【００２６】
両端には光学接続部品１１〜２６である８芯ＭＴ光コネクタを接続した。電子線架橋軟質難燃性ポリオレフィン樹脂の熱収縮チューブ２７〜４２で光ファイバ素線を被覆保護することにより、光ファイバ素線の破断が無くなり、また、光ファイバ素線を保護しているため、光ファイバ素線状態時よりも取扱い易くなり、作業性の向上や信頼性の向上に繋がった。
【００２７】
また、光配線板本体部まで電子線架橋軟質難燃性ポリオレフィン樹脂の熱収縮チューブ２７〜４２を挿入したことにより、光配線板の端部と熱収縮チューブ端部との間に隙間は出来ず、光ファイバ素線が破断することは無くなった。さらに難燃性の熱収縮チューブを使用していることで、光ファイバ部に難燃性を付与することができ、信頼性の向上に繋がった。
【００２８】
また、光配線板の損失を測定したところ、０．５ｄＢ以下と光コネクタの挿入損失と同等であり、従って、上述した被覆保護構造による損失増加は無く、光学特性的にも実用性が高いことが分った。
【００２９】
［実施例２］
図６は、本発明の光配線板装置の具体的な実施例２を示す図で、２つの４芯テープ化した光ファイバ素線１３５〜１３７、１３８〜１４１を各８ポートに分離する機能を有する光配線板１４２を示している。
【００３０】
光配線板装置１４２の構造は、厚さ１２５μｍのポリイミドシート上に粘着剤を塗布し、光ファイバ素線を布線した後に周りに堰状物１４３を設け、その上部からシリコーン系材料で形成された樹脂を流し込んだ。その際、４芯テープ化した光ファイバから各８ポートに分離する外径２５０μｍの光ファイバ素線をポリエステルエラストマーチューブ１４４〜１５１で被覆保護し、ポリエステルエラストマーチューブ１４４〜１５１を堰状物１４３まで挿入させた。
【００３１】
４芯テープ化した光ファイバ及びポリエステルエラストマーチューブ１４４〜１５１で被覆保護した８つの光ファイバ素線に、それぞれ４芯ＭＴ光コネクタ１３２〜１３３とＭＵ光コネクタ１２４〜１３１の光学接続部品を接続した。ポリエステルエラストマーチューブ１４４〜１５１を堰状物１４３まで挿入させたことにより、光配線板端部とポリエステルエラストマーチューブ端部との間に隙間が無くなり、光ファイバ素線が破断することは無くなった。
【００３２】
また、破断を恐れる必要が無くなったため取扱い易くなり、作業性の向上や信頼性の向上にも繋がった。さらに難燃性のポリエステルエラストマーチューブを使用していることで、光ファイバ部に難燃性を付与することができ、信頼性の向上に繋がった。また、光配線板の損失を測定したところ、光コネクタの接続損失を含めて０．５ｄＢ以下と良好であった。
【００３３】
以上、本発明の具体的な実施例について説明したが、本発明は上述した各実施例に限定されず、本発明の技術思想の範囲内において、各実施例は適宜変更され得ることは明らかである。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an optical wiring board device, and more particularly, to an optical wiring board device used for a high-speed communication device or an information processing device using an optical circuit such as an optical element, an optical component, an optical circuit board, and an optical circuit device. About.
[0002]
[Prior art]
2. Description of the Related Art In recent years, optical fiber cords using optical fibers as signal transmission lines have been frequently used with the advancement of communication devices. However, when a large number of optical fiber cords are connected to the front or rear surface of the device, the bundle of optical fiber cords occupies a large space, and at present, problems such as storability and incorrect connection occur. In order to solve these problems, an optical wiring board has been used (for example, see Patent Document 1).
[0003]
This optical wiring board has a structure in which at least one optical fiber strand arranged in an arbitrary shape is covered on a base material coated with an adhesive or the like with a resin or a flexible base material from the upper surface thereof. In addition, an optical fiber for connecting to an optical connection component such as an optical connector (hereinafter referred to as an optical connector) is exposed from an end of the optical wiring board.
[0004]
This optical fiber strand does not have a protective material around the optical fiber as compared with the optical fiber cord and is very thin. When attaching an optical connector or the like to an optical fiber exposed from the end of the optical wiring board, it is necessary to polish the end face of the optical connector or the like so as not to cause loss of light.
[0005]
When performing the polishing operation, the optical connector or the like attached to the optical fiber exposed from the end of the optical wiring board must be fixed to a polishing jig and then subjected to polishing. In this case, between the optical wiring board and the optical connector or the like, the optical fiber is broken unless careful attention is paid to the mounting of the polishing jig or the polishing process on the optical fiber. There is fear.
[0006]
Also, when the work of attaching the optical wiring board to the apparatus after the polishing is completed, the optical wiring board is attached and detached by attaching and detaching the optical connector or the like attached to the optical fiber exposed from the end of the optical wiring board. The optical fiber between the cable and the optical connector is easily broken. If the optical fiber in this portion breaks, the optical connector or the like is reattached, or if there is no remaining optical fiber length enough to reattach the optical connector or the like, the optical wiring board cannot be used.
[0007]

[Problems to be solved by the invention]
As described above, since the optical fiber bare exposed from the end of the optical wiring board is easily broken, there is a problem that the yield of the optical wiring board is reduced, and the workability in attaching and detaching the optical wiring board to and from the optical wiring apparatus is reduced. Was. Furthermore, optical wiring devices are required to have high flame retardancy. However, for the main body of the optical wiring board, a flame-retardant base material such as polyimide can be used, but since the optical fiber does not have a flame-retardant coating material, the entire optical wiring board is completely However, there is a problem that high flame retardancy cannot be obtained.
[0009]
Conventionally, in order to solve these problems, the exposed optical fiber is covered with a tube, a heat-shrinkable tube or the like for protection. However, a gap is formed between the end of the optical wiring board and the end of the tube or the heat-shrinkable tube. As described above, when handling the optical fiber, the load is applied to the optical fiber in this gap. In this case, the optical fiber is easily broken at this point, and a gap is formed between the end of the optical wiring board and the end of the tube or the heat-shrinkable tube even in the flame retardancy. Therefore, the problem that high flame retardancy cannot be obtained still remains.
[0010]
The present invention has been made in view of such a problem, and its object is to improve the yield of an optical wiring board in mounting and polishing of an optical connection component, to improve workability in a removal work, and to shorten work time.
