【０００３】
【特許文献１】
特開２００２−３７２６３４号公報（第３−４頁、第６，９図）
【０００４】
【発明が解決しようとする課題】
従来のスプライスユニットは融着トレイが前後方向にスライド可能に設けられて配線作業性を向上させているが、ユニット本体から融着トレイが完全に突出する構造ではなく、ユニット本体内に手を差し入れて狭い空間で作業を行わなければならないので作業性が悪いという欠点があった。
【０００５】
そこで上記問題点に鑑み、本発明の目的は、光ファイバの配線作業性が良好なスプライスユニットを提供することである。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、箱状のユニット本体の内部に光ファイバコードの余長と光ファイバ心線の融着部とを収納可能にしたスプライスユニットにおいて、ユニット本体の前面に光ファイバコード同士をコネクタ接続するための多数のアダプタが設けられたアダプタパネルを観音開き式に開閉自在に蝶着するとともに、ユニット本体を少なくとも前面が開放した箱状のアウターシャーシに収納してアウターシャーシに対しユニット本体をスライド可能にし、ユニット本体をアウターシャーシに収納した状態に保持するためのロック部と、ユニット本体をアウターシャーシから引き出した際に脱落を防止するためのストッパーとを備えたことを特徴とする。
【０００７】
【発明の実施の形態】
スプライスユニットはユニット本体とアウターシャーシとで構成し、ユニット本体の前面は多数のアダプタが設けられたアダプタパネルが開閉自在に蝶着され、ユニット本体は前面を開口したアウターシャーシに前後方向にスライド可能に収納される。ユニット本体の前面下部にはラッチが設けられ、アウターシャーシに収納した際に飛び出さないように保持することができ、また、ユニット本体の下面のレールの長孔にアウターシャーシに固定された棒状のストッパーが挿通して設けられ、ユニット本体を引き出した際に脱落しないようにされている。
【０００８】
【実施例】
本発明に係るスプライスユニットの実施例を図１〜図５の添付図面に基づいて説明する。
【０００９】
スプライスユニット１は、ユニット本体２と、アウターシャーシ３とで構成し、ユニット本体２は矩形状の底板４と、左右側板５とで前面と背面と上面を開放した箱状に形成され、上面は天板６が前部のネジ７と後部の引っ掛け爪８によって着脱可能に閉塞されている。
【００１０】
ユニット本体２の前面は光ファイバコード９同士をコネクタ接続するための多数のアダプタ１０が設けられた２枚のアダプタパネル１１が左右側板５の前端縁に観音開き式に開閉自在に蝶着されて取り付けられている。アダプタパネル１１の夫々の開放端にはラッチ１２が設けられている。ラッチ１２は押し操作するとアダプタパネル１１の裏面に突出した先端の径が大きくなり、引き操作すると先端の径が小さくなる構造になっており、アダプタパネル１１を閉塞するとユニット本体２の底板４の前端中央に立設した係合片１３の係合孔１４にラッチ１２の先端が挿通するため、その状態でラッチ１２を押し操作すると先端の径が係合孔１４より大きくなって係合してアダプタパネル１１を固定することができる。また、アダプタパネル１１を開放するにはラッチ１２を引き操作して係合片１３との係合を解除して行う。
【００１１】
アダプタパネル１１は下端が前方に張設され、光ファイバコード９を支持するための支持部１５が形成されている。これによってアダプタ１０の前面側接続口に光ファイバコード９を接続すると垂れ下がった部分が支持部１５に支持されるので自重による負荷がかからず、破損を防止することができる。アダプタ１０に接続した光ファイバコード９は支持部１５の端部に形成されたコード結束用スリット孔１６に挿通して設けられた結束バンド１７で結束され、外側に出線される。
【００１２】
底板４は多数の通気用スリット１８が形成され、軽量化も図られ、また、光ファイバコード９を保持するための結束バンド等を挿通させて設けるためにも用いられる。底板４の上面には光ファイバ心線同士を接続した融着部と、その融着時に発生する余長とを収納するための融着トレイ１９が配設されている。底板４の下面には奥行き方向へ延びるレール２０が左右両端と中央に設けられている。
【００１３】
アウターシャーシ３は前面と背面と上面を開放した箱状に形成され、左右側板２１の上端部を内側方向に折曲してユニット本体２を前後方向にスライド可能に収納する。ユニット本体２の左右側板５の上端部もアウターシャーシ３の折曲部に沿うように内側方向に折曲形成されている。アウターシャーシ３の底板４の後端部はコードクランプ２２が設けられ、コードクランプ２２の前方にはフレキシブルダクト２３の一端が固定され、他端はユニット本体２の後端部に固定されている。アウターシャーシ３の背面から導入した光ファイバコード９はコードクランプ２２によって保持され、フレキシブルダクト２３内を挿通してユニット本体２内へ配線される。
【００１４】
ユニット本体２内に導入された光ファイバコード９を配線するにはアウターシャーシ３からユニット本体２を引き出して行う。引き出すには、まず、アウターシャーシ３とユニット本体２とのロックを解除する。アウターシャーシ３とユニット本体２はロック部としてのラッチ２４によって係脱自在にされており、ラッチ２４の構造はユニット本体２のアダプタパネル１１のラッチ１２と同様であり、アウターシャーシ３の底板２５の前端部に設けた係合片２６の係合孔２７にユニット本体２の前端下部に設けられたラッチ２４の先端が係脱可能になっている。
【００１５】
ユニット本体２をアウターシャーシ３から引き出した際にユニット本体２が脱落しないようにアウターシャーシ３にはストッパー２８が設けられている。ストッパー２８は棒状に形成され、ユニット本体２のレール２０の長手方向に形成された長孔２９に挿通し、両端をアウターシャーシ３の左右側板２１に固定して設けられている。これによってユニット本体２を引き出してもストッパー２８が長孔２９の端部に当たるので脱落しない。
【００１６】
ユニット本体２を引き出した後、アダプタパネル１１を開放し、天板６を取り外してユニット本体２内の配線を行う。尚、配線の際に発生した余長はユニット本体２の底板４上に丸めて収納しておく。ユニット本体２の前面と上面が開放できるため、配線作業性が非常に良好である。配線が完了したら天板６を取り付け、アダプタパネル１１を閉塞し、ラッチ１２をロックしてアダプタパネル１１を固定する。それから、ユニット本体２をアウターシャーシ３内に押し込み、ラッチ２４によってロックしておく。尚、光ファイバコードの接続変更だけであれば、天板７を取り外さずにアダプタパネル１１を開放させるだけで行うことができる。
【００１７】
アウターシャーシ３の左右側板２１には光配線盤（図示せず）や通信機器等を収納するためのラック（図示せず）等にマウント取り付けできるように左右に張設されたマウント部３０が設けられ、マウント部３０は２個の挿通孔３１が穿設されている。マウント部３０を光配線盤やラック等の内部に立設されたマウントアングルに前面側から当接させ、挿通孔３１に前面側から取付ネジを挿通させてマウントアングルに螺着固定することによりスプライスユニット１を取り付けることができる。
【００１８】
尚、本実施例において、ユニット本体のスライド構造、ストッパー構造やロック構造等、スプライスユニットの構造について限定はなく、本発明の趣旨を逸脱しない範囲で適宜変更可能である。
【００１９】
【発明の効果】
以上説明したように、箱状のユニット本体の内部に光ファイバコードの余長と光ファイバ心線の融着部とを収納可能にしたスプライスユニットにおいて、ユニット本体の前面に光ファイバコード同士をコネクタ接続するための多数のアダプタが設けられたアダプタパネルを観音開き式に開閉自在に蝶着するとともに、ユニット本体を少なくとも前面が開放した箱状のアウターシャーシに収納してアウターシャーシに対しユニット本体をスライド可能にし、ユニット本体をアウターシャーシに収納した状態に保持するためのロック部と、ユニット本体をアウターシャーシから引き出した際に脱落を防止するためのストッパーとを備えたことにより、光ファイバの配線作業性が良いという効果がある。
