Description
本願は、2011年3月30日に、日本に出願された特願2011-075278号に基づき優先権を主張し、その内容をここに援用する。
この構成の光ファイバ用被覆除去具は、光コネクタに用いられる外被把持部材に把持された光ケーブルに適用することができる。
この構成の光ファイバ用被覆除去具は、光ファイバホルダに保持された光ファイバに適用することができる。
これにより、外被把持部材又は光ファイバホルダをストッパに突き当てた状態から被覆を除去することによって、被覆が裸光ファイバを被覆する寸法を、ストッパの位置に応じて一定にすることができる。
以下、本発明の実施形態について図面を参照して詳細に説明する。
本実施形態のストリッパ10は、光ファイバケーブル60(図4参照)の端末部から延出する光ファイバ素線61の被覆を除去し、光ファイバ裸線61aを露出させる光ファイバ用被覆除去具である。
光ファイバケーブル60は、ドロップケーブルや、屋内配線用のいわゆるインドアケーブルとして用いられるものであり、図示例では光ファイバ素線61を1本だけ内蔵した単心のものを例示している。
以下、アーム部材2の延出方向(長手方向)を、単に長手方向という。なお、以下、ストリッパ10について、アーム部材2の側を前方、本体部1の側を後方として説明する。例えば、図2において、左側が前方、右側が後方である。また、図3において、上側を上、下側を下として説明する。
壁部4,4は前後方向に厚みを有する矩形板状の部位である。図3に示すように、壁部4,4は空間をおいて左右に形成されている。2つの壁部4,4の間の空間は、ストリッパ10にコネクタ付光ファイバ50の外被把持部材51を組み込んだ際に光ファイバ素線61が延在するための空間である。
さらに、ガイド溝7の前端であって、壁部4の後面4aは、図4に示すように、コネクタ付光ファイバ50をガイド溝7に沿って挿入した際、外被把持部材51の前端が当接するストッパとして機能する。
アーム部材2の操作部16の互いに対向する内側である一面16aには、楔形状の当接部11がアーム部材2と一体に形成されている。当接部11は楔の先端辺11aが上下方向に延在するように、かつ、各々の先端辺11aが相対向し、アーム部材2の変形部15を弾性変形させることによって、先端辺11a同士が当接する位置に形成されている。先端辺11aは、完全な鋭角形状ではなく、楔の先端が面取りされた面形状となっている。
この面の前後方向の厚みは1mm程度が好ましい。また、各々のアーム部材2の先端側であって、夫々の操作部16の外側、つまり、当接部11が形成されている一面16aの反対側の面には、把持部12が設けられている。把持部12においては、アーム部材2の左右方向の厚みが、より厚くなっていると共に、上方から見て左右方向の側面が凹円弧状に形成されている。
次いで、把持部12,12を把持し、当接部11の先端辺11aどうしを光ファイバ素線61を介して近接させるように変形部15を変形させる。これにより、光ファイバ素線61に当接部11の夫々の先端辺11aを当接させ、先端辺11aを被覆に食い込ませる。この状態で、図5Cに示すように、コネクタ付光ファイバ50を後方に引っ張ることで、被覆が引き千切られ、光ファイバ素線61から被覆が除去される。
また、外被把持部材51を壁部4の後面4aに突き当てることによって、外被把持部材51を被覆除去の開始位置に位置決め可能であり、被覆が裸光ファイバを被覆する寸法を一定にすることができる。
なお、壁部4の後面4aと当接部11の先端辺11aとの前後方向の距離寸法は、外被把持部材51を含んで組み立てられる光コネクタの仕様により適宜設定される。
次に、本発明の第二実施形態について図面を参照して詳細に説明する。
本実施形態は、光ファイバホルダ20(図7参照)に固定された光ファイバ素線61の被覆を除去するためのストリッパであり、第一実施形態のストリッパとは、本体部1Bの形状が異なる。
さらに、アーム部材2Bの後面27は、図7に示すように、光ファイバホルダ20をガイド壁26に沿って挿入した際、光ファイバホルダ20の前端が当接するストッパとして機能する。
ベース部21は、合成樹脂、金属などで構成され、図示例では略長方形の板状とされている。ベース部21の上面には、光ファイバ素線61を保持する位置決め溝23が、ベース部21の長手方向に沿って直線状に形成されている。図示例の位置決め溝23は、断面略V字状とされている。また、ベース部21の前方にも離間して位置決め突起24が設けられている。
また、光ファイバホルダ20をアーム部材2Bの後面27に突き当てることによって、光ファイバホルダ20を被覆除去の開始位置に位置決め可能であり、被覆が裸光ファイバを被覆する寸法を一定にすることができる。
