本発明は、通信ケーブル、特に光ファイバ心線を有する光ファイバケーブル(以下光ケーブル)の光回路設備において、ケーブル心線使用率および需要変動対応力を大幅に高める切換・配線機能を備えた光ケーブル接続切換用クロージャ、特にクロスコネクト用クロージャに関するものである。
【0002】
【従来の技術】
従来、光ケーブルの分岐、引込、接続などを行う場合、クロージャ内においてケーブル心線相互を接続すると共に、該接続部と、ケーブル心線の余長分とを収納するための心線接続余長収納トレイを備えたクロージャが知られている。
このクロージャでは、心線幹線用光ケーブルの本線から引き出された光ファイバ心線同士或いは分岐用光ケーブルから引き出された心線とを接続するコネクタ等の接続部が収納され、さらに接続された心線の余長部分を巻回して保護収納する心線余長収納部とを備えたものとして接続機能専用クロージャ、或いはドロップ機能専用クロージャとして用いられている。
【0003】
【発明が解決しようとする課題】
ところが、光ケーブルを用いた通信網では、光アクセス網の最適な配線形態とすることや、光アクセスサービスを迅速かつ安価に提供することが要請されているためと、光回線路設備の初期投資を最小化するために、クロージャでは極限まで高密度配線が施されているため配線管理の識別が難しく、見にくいものや、誤作業による信頼性がなくなったり、現場の状況によっては現場作業に適さなかったり、管理作業時間も掛かりすぎたりして問題があって、しかも顧客の要望素早く対応できず、早期なサービス提供ができなかったり、光アクセス系設備の効率的な使用や経済的な使用が十分満足するものがない。
特に、ケーブルの高密度、多心化或いは伝送高速度化が進むにつれて、また通信競争の激化により需要の変動が大きく変化することも予想され接続分岐に伴う切換作業や配線整理がやりにくいし、さらには増設も簡単には対応できずコンパクト化できないといった問題が生じていて、アクセス系設備の効率的かつ経済的な使用ができないなど問題があった。
【0004】
本発明は、これら従来の事情に鑑みてなされたものであり、光ケーブル配線の心線ごとの接続機能と切換機能とを統合して整理することができ、その収納並びに心線ごとの増減が簡単にでき増設も楽で、光ケーブルの光回線路設備の初期投資を軽減し、サービス需要の増加に効率的に対応していけ、心線の使用効率および需要変動対応力を大幅に高めることができる切換・配線機能を持った光ケーブル接続切換用クロージャとする。特に、高密度の配線をリアルタイムに素早く、簡単に読み取れ、その識別を容易にしてサービスオーダーから設計、施工、保守までの各工程の企画、管理の簡易化ができ、しかもアダプタの抜き差しによる簡易な操作で確実な心線切替えができるほか、光回線路設備の線番、ルート情報、接続/切換の接続履歴情報などの設備情報を現場でリアルタイムに更新管理でき、サービスの即応化、低コスト化とが図られるし、管理センターからのデータをもアクセスして設備情報などをアップデートすることも可能で、確実な切換・配線の施工を行えて、配線管理作業の信頼性も向上すると共に、配線識別にクロージャの外側からでも簡単に読み取れ、工事対応のクロージャを素早く捜し出すことも可能であり、管理作業時間の削減と、現場作業に適した作業が容易に実施できて施工性に優れ、きわめてコンパクトに接続部を収納することができる取扱い簡便な光ケーブル接続切換用クロージャを安価な形態で提供することを目的とするものである。
【0005】
【課題を解決するための手段】
上述の課題を解決するために、この発明は、光ケーブル心線を導出入する心線導出入部と、該心線導出入部から入る心線を支持する心線保持部と、該心線相互を接続したコネクタを収納するコネクタ収納部と、心線余長を巻回して収納する心線余長収納部とを備えた接続用トレイと、保留心線用トレイと引き通し心線用トレイをスリーブ内に配備する光ケーブル接続切換用クロージャであって、光回線の管理情報を記録、記録データの分配、保存、更新作業の管理を総合的に行ない読み書き可能なもので前記光ケーブル心線の回線データをディジタル化されたうえでパターン表示されている2次元コードまたはRFID素子(Radio Frequency Identification Device)からなる回線路識別用チップをスリーブ内に備えたアダプタのあるアダプタ保持部材における各回線路の心線のアダプタ毎に対応する位置に配備したことを特徴とする。
【0006】
また、このケーブル接続切換用クロージャにおいて、前記接続用トレイは、複数を積層して各接続トレイをヒンジ部で回動自在に連結してなり、スリーブ内中央に積層して配備した前記保留心線用トレイと引き通し心線用トレイとの両側に設けると共に、保留心線用トレイと引き通し心線用トレイとの上方にアダプタ保持部材を配備してある。
【0007】
さらに、本発明の光ケーブル接続切換用クロージャにおいては、前記アダプタ保持部材が中央を凸状に折り曲げた平板で構成され、ヒンジ部で回動自在に支持部に連結され、スリーブ内の前記保留心線用トレイと引き通し心線用トレイ上を開放できる構成としたことを特徴とし、接続配線作業が容易に実施できて施工性に優れ、心線ごとの接続機能と切換機能とを統合して整理することができ、その収納並びに心線ごとの増減が簡単にでき増設も楽で、きわめてコンパクトに接続部を収納することができる取扱い簡便で、信頼性のある光ケーブル接続切換用クロージャとしている。
【0008】
【作用】
本発明の光ケーブル接続用クロージャは、光ケーブル心線を導出入して収納する接続用トレイと、保留心線用トレイと引き通し心線用トレイをスリーブ内に配備する光ケーブル接続切換用クロージャに、前記光ケーブル心線の回線データをディジタル化されたうえでパターン表示されている2次元コードまたはRFID素子からなる回線路識別用チップをスリーブ内のアダプタ保持部材で各光回線路のアダプタ毎に対応した位置に配備してあるので、回線路識別用チップを携帯端末によって読み書きして高密度の配線をリアルタイムに素早く、簡単に読み取れ光ケーブル配線の心線ごとの接続機能と切換機能とを統合して整理することができ、その収納並びに心線ごとの増減が簡単にでき増設も楽で、心線の使用効率および需要変動対応力を大幅に高めることができる。またこのスリーブ内のアダプタ保持部材に配備した回線路識別用チップは、光回線路設備の線番、ルート情報、接続/切換の接続履歴情報などの設備情報を現場でリアルタイムに更新管理でき、サービスの即応化、低コスト化とが図られるし、管理センターからのデータをもアクセスして設備情報などをアップデートすることも可能である。
そして、アダプタ保持部材に配備したアダプタの抜差自在の心線切替構造としたことによって簡易で、確実な心線切替えができるので、ユーザーの加入、移転など必要な回線として接続、切替え使用することができ、心線ごとの接続機能と切換機能とを統合して整理し、他の心線の接続作業や接続状況の点検、補修、確認、調整など作業をもきわめて容易に行うことができる。
【0009】
【発明の実施の形態】
本発明の実施例を図面を用いて説明すると、図1に示す心線接続クロージャ1には、光ケーブルの幹線ケーブルaを導出入して支持するケーブル把持部2が備えられ、心線接続クロージャ1内に心線を導出入して収納する接続用トレイ3と、保留心線用トレイ4と引き通し心線用トレイ5をスリーブ6内に配備する光ケーブル接続切換用クロージャであって、前記光ケーブル心線の回線データをディジタル化されたうえでパターン表示されている2次元コードまたはRFID素子 からなる回線路識別用チップ7をスリーブ内に配備してクロスコネクト用クロージャとしてある。
【0010】
この回線路識別用チップ7としては、マトリックス方式の2次元コードでデータをディジタル化されて角形のパターンに表現されているものまたは、外部から無線(電磁誘導)により特殊半導体メモリーチップに給電を行ない、所定のデータのリード/ライト動作をワイヤレスで行なうデバイスのRFID素子 を用い、光回線の管理情報を記録、記録データの分配、保存、更新作業の管理を総合的に行ない読み書き可能なものの2次元コードまたはRFID素子7 からなる回線路識別用チップ7を、各回線路の心線の接続部となるアダプタ8に対応する位置にアダプタ保持部材9に配備する。
この場合、前記アダプタ8は、アダプタ保持部材9の凸状に折り曲げた側面壁に一段または複数段に並列して配備し、該アダプタ8に沿って配線されるラインに合わせた位置で上面壁の上に、前記回線路識別用チップ7を貼着配置して、回線路識別がし易くてある。この回線路識別用チップ7では、光回線路設備の情報としての配線回路の線番、ルート情報、接続/切換暦情報等が、アダプタ毎に識別されるものであり、該回線路識別用チップ7により、作業現場において各情報のリアルタイムでの読取りをして、その線路情報等を確認した上で、配線切替え作業を行うことができると共に、その情報の更新も行うことができるものを用いる。
また、回線路識別用チップ7は、2次元バーコードまたはFRID素子7を単独或いは併用して回線路識別用チップ7とすることができる。例えば、2次元バーコードをアダプタ保持部材9に貼着しないで前記配線側に取付片またはシートを介して取付けたり、アダプタ保持部材9或いはアダプタ側に貼着した上で、かつ配線側にも取付片を介して取付て、さらにFRID素子7をアダプタ保持部材9に設けた形態とした併用タイプとすることもできる。
【0011】
そして、前記RFID素子素子7では、光回線路設備の切替接続情報管理以外にクロージャの外側からでも携帯末端、携帯電話機によって作業に必要な事項を認識できて、工事対応のクロージャをも素早く捜し出して、作業の施工性の簡便化を図れるものを用いるのがよい。
また、このように光ケーブル接続切換用クロージャと携帯末端、携帯電話機との組み合わせによって、リアルタイムな設備情報、工事履歴などの一括管理をもセンター側でも可能なものを用いるのがよく、特に、前記携帯末端が管理センターへアクセスしうるもので、管理センターからの情報の遠隔伝送を受け、該情報の照合をもしうるものであることが望ましい。
そして、光回線路設備での作業終了後に管理センターにアクセスし、回線路識別用チップ7の履歴情報等をアップデイトすることや、アダプタ毎に識別された回線路識別用チップ7によって線路情報等を確認した上で、切替え作業を行うことができることが配慮されている。
【0012】
更に、この光ケーブル接続切換用クロージャの例では、前記接続用トレイ3が光ケーブル心線を導出入する心線導出入部10と、該心線導出入部10から入る心線を支持する心線保持部11と、該心線相互を接続したコネクタを収納するコネクタ収納部12と、心線余長を巻回して収納する心線余長収納部13とを備えていて、該接続用トレイ3の複数を積層して各接続トレイ3をヒンジ部14で回動自在に連結してあり、クロージャ1の中央に位置する保留心線用トレイ4と引き通し心線用トレイ5の両側にそれぞれ配置して心線接続作業が簡便にできるように配慮してある。
【0013】
なお、前記保留心線用トレイ4と引き通し心線用トレイ5とをスリーブ内中央に積層して配備し、その両側に前記接続用トレイ3を複数積層して設けると共に、保留心線用トレイ4と引き通し心線用トレイ5との上方にアダプタ保持部材9を配備し、該アダプタ保持部材9は、中央を凸状に折り曲げた平板15で構成し、この折り曲げ平板15をヒンジ部16で回動自在に支持部材17に連結されたものからなり、スリーブ6内の前記保留心線用トレイ4と引き通し心線用トレイ5の上を開放できる構成とするのが、配線作業、その他の心線の接続作業や接続状況の点検、補修、確認、調整など作業をもきわめて容易に行うことができる。
【0014】
そして、接続用トレイ3及び保留心線用トレイ4と引き通し心線用トレイ5とは、合成樹脂により一体成形された成形品であり、図1に示すように、略長方形状の外形を有し、各トレイ3,及びトレイ4,5を重ねた状態の心線トレイとして用い、前記トレイ内にガイドリブ或いは心線係止片30をそれぞれ設けて、トレイ内を区画して、心線をトレイ内に引き廻し、ループ状に巻回させて収納されるものである。
【0015】
前記スリーブ6としては、角筒或いは円筒状のケーシングを用いてあり、図2乃至図3に示すように上スリーブと下スリーブとに二つ割りに分割するようにし、上下スリーブを脱着用のヒンジ締結具20(ハンドル付きグリップ)で密封一体化できる構成としたものをいるのがよい。
このスリーブ6内には、幹線ケーブルaのテンションメンバが固定できるテンションメンバ把持部21が備えられ、さらに引き上げケーブルbがケーブル把持部22を介してテンションメンバ把持部23で固定できるようにしてある。
この場合、前記接続用トレイ3は、最下段の接続用トレイ3を、下スリーブ内に固着したフレーム24に設けた取付台25に載置し配線の分配、整理して収納できるようにするのがよい。
【0016】
例えば、図4の例示のように固定局線(固定線区画の5年後の需要数に分割損をみこんだ心線)と補助線(需要変動に対する融通性を確保するめ、固定局線の他に設ける心線)と連絡補助線(補助線のうち固定線区画に連絡して設ける補助線)とを配線したクロスコネクト用クロージャの配線例では、200心の幹線ケーブルaをクロスコネクト用クロージャNo.1において、2つの40心の固定局線cと2つの40心の補助線dとに分岐し、この固定局線cは切換アダプタ8を介して引き上げケーブルbとして導出すると共に、補助線dは切換アダプタ8を介して連絡補助線eとしてクロスコネクト用クロージャNo.2に導出する。そして、該クロスコネクト用クロージャNo.2においては、前記と同様に幹線ケーブルaを2つの40心の固定局線cと、2つの40心の補助線dとにさらに分岐し、補助線dはクロスコネクト用クロージャNo.2において40心の補助線dとして切換アダプタ8を介して連絡補助線eによりクロスコネクト用クロージャNo.3に導出する。さらにこのクロスコネクト用クロージャNo.3において、残りの幹線ケーブルaを40心の固定局線cと40心の補助線dとに分岐して、固定局線cは、切換アダプタ8を介して引き上げケーブルbとして導出すると共に、補助線dも切換アダプタ8を介して連絡補助線eとしてクロスコネクト用クロージャNo.4に導出する。そしてクロスコネクト用クロージャNo.4においては、幹線ケーブルaを40心の固定局線cと40心の連絡補助線eを補助線dとに分岐して、固定局線cは、切換アダプタ8を介して引き上げケーブルbとして導出すると共に、連絡補助線eは、固定配線区画に配線され、各切換アダプタ8において、光回線路設備での配線点の切換・配線機能を行うことができる。
【0017】
なお、この実施例では、前記接続用トレイ3は、4〜5段のトレイの多段積層ケースの場合には1トレイ,20心で80〜100心、また1トレイ、40心では160〜200心の収納トレイとして用いられているので高密度配線に適している。
そしてテープ接続100心収納や200心収納のときになど適宜選んで上段から下段に使用(分岐心線使用)でき、また、下段から上段に向けて各段を有効利用することができ、テープ接続心の数量に対応して増設の場合は各トレイの装着を1段最上段に増設することにより適応することができる。
【0018】
また、前記接続用トレイ3に形成した心線導出入部11には、分離スリットのある心線挿通孔を設けた弾性保持部材(図示せず)を圧入嵌合して心線の支持を確実にしてあり、この弾性保持部材は心線径或いは心線数に応じた挿通孔のあるナイロンチューブを選んで用いられる。
さらに前記コネクタ収納部12、心線余長収納部13は、必要に応じガイドリブ及び側壁を選んで区画してもよいし、心線の浮きを阻止する心線係止片30或いは係止爪を一体成形して、余長の心線や心線接続部となるコネクタをトレイ内に確実に保持できるようにするか、またコネクタ収納部12或いは心線余長収納部13のみを区画したトレイを組合せて一つとした形態としてもよく、各上下段トレイ毎に心線を分離整理収納し、ケーブル挿入部からファイバ心線の曲げが極少で心線収納時のねじれをも防止でき、安全かつ高密度収納で高信頼性が得られるようにすることが配慮される。
【0019】
この場合、多段に積み重ねられた接続用トレイ3の中から選んだ一つの接続用トレイ3を引き起こして開いて重ね合せ面を開くことができて、接続用トレイ3の内面側が露出されて収納心線の接続配線作業が容易にできる。
【0020】
即ち、上方の接続用トレイ3のヒンジ16を支点として一端を回動すれば、下方の接続用トレイ3の上面を開くことができ、接続用トレイ3内において、分離した心線の接続部の収納や心線余長を収納保管或いは新たな分岐作業並びに配線系の点検、補修、確認、調整など各作業をも統合してきわめて容易に行うことができる。
【0021】
前記光ケーブル心線の接続用トレイ3及び光ケーブル心線の光ケーブル心線回線データをディジタル化されたうえでパターン表示されている2次元コードまたはRFID素子からなる回線路識別用チップ7は、脱着自在に定着する二つ割りのスリーブ6からなる筒状のクロージャ1内に組み込まれて用いられるが、クロージャ1内のフレーム24には配線処理ガイド18、19と、ケーブル把持金具とテンションメンバ把持具21、23とを一体に形成され、ケーブルa,bの配置固定が確実にできるようになっている。
【0022】
前記クロージャ1のスリーブ6の両端壁の嵌合部に嵌装された端面板を備えたクロージャ1の例で説明すると、端面板をスペーサ(図示せず)を介して、幹線光ケーブルaが貫通されてケーブル把持金具2で固定され、かつ、該ケーブルのテンションメンバが、テンションメンバ把持金具21に接続連結されている。
また主線光ケーブルaから分岐導出されたテープ心線は、接続用トレイ3に処理されて端面板から導出されて引き通しケーブルbとして配線される。(図1)
前記スペーサには、ケーブルの挿通用の閉塞孔を多数備え、引落し時に閉塞孔を開口してケーブルをクロージャ外に導出入できるようにしてある。さらに、前記クロージャ1は、分割接合面にガスケットを介在して突き合わせ密封結合するが、スリーブ外側に設けたヒンジ部にループ状リングからなるヒンジ締結具20によって掛止めて連結一体化するようになっている。
【0023】
なお、前記接続用トレイ3には曲率半径30mm以上を確保して心線の取り回し、収納ができ、各種の接続部、例えば、融着補強スリーブ、メカニカルスプライス、MTコネクタなどの収納可能であって、接続用トレイ3を4段に積層し、各心線トレイ単位で開閉或いは脱着可能に設け、心線余長と心線接続部を一括収納できる。
【0024】
【発明の効果】

【0025】
また本発明によれば、光ケーブル接続切換用クロージャに備えた前記接続用トレイが光ケーブル心線を導出入する心線導出入部と、該心線導出入部から入る心線を支持するケーブル把持部と、該心線相互を接続したコネクタを収納するコネクタ収納部と、心線余長を巻回して収納する心線余長収納部とを備え、該接続用トレイの複数を積層して各接続トレイをヒンジ部で回動自在に連結してなることと、前記保留心線用トレイと引き通し心線用トレイとをスリーブ内中央に積層して配備し、その両側に前記接続用トレイを設けると共に、保留心線用トレイと引き通し心線用トレイとの上方にアダプタ保持部材を配備したことにより、心線の接続部の収納や心線余長の収納保管のほか分岐作業並びに配線系の点検、補修確認、調整などの接続配線作業が容易に実施できて施工性に優れ、心線ごとの接続機能と切換機能とを統合して整理することができ、その収納並びに心線ごとの増減が簡単にでき増設も楽で、きわめてコンパクトに接続部を収納することができる取扱い簡便で、信頼性のある光ケーブル接続切換用クロージャにできる。
【0026】
