Abstract
Description
本出願は、2021年2月26日出願の日本出願第2021-030264号に基づく優先権を主張し、前記日本出願に記載された全ての記載内容を援用するものである。
光ファイバを切断する光ファイバ切断装置であって、
前記光ファイバの位置決めをする位置決め部と、第1の磁石と、を有する本体と、
前記光ファイバに傷を付ける刃部と、第2の磁石と、を有し、第1の位置と第2の位置との間を移動可能に前記本体に取り付けられた移動部と、を備え、前記第1の位置から前記第2の位置まで前記移動部が移動する間に前記刃部によって前記光ファイバに傷をつけることが可能であり、
前記移動部が前記第2の位置にある場合において、
前記第2の磁石は前記第1の磁石と同極側が互いに向き合う位置であって、かつ、前記第1の磁石よりも前記第1の位置に近い側にある。
光ファイバ切断時の作業性を向上させるため、光ファイバの切断後にスライダを初期位置付近まで自動で戻すことが望ましい。特許文献1に開示された光ファイバ切断装置は、第1磁石と第2磁石の磁力関係を検討しているが、例えば、第1磁石と第2磁石の位置関係についての検討が十分ではなく、スライダをスムーズに初期位置まで戻すという点で改善の余地があった。また、特許文献2に開示された光ファイバ切断装置は、例えば、スライダの移動のために4つの磁石を使用しており、より簡単な構成を追求する余地があった。
本開示の一態様に係る光ファイバ切断装置は、
光ファイバを切断する光ファイバ切断装置であって、
前記光ファイバの位置決めをする位置決め部と、第1の磁石と、を有する本体と、
前記光ファイバに傷を付ける刃部と、第2の磁石と、を有し、第1の位置と第2の位置との間を移動可能に前記本体に取り付けられた移動部と、を備え、前記第1の位置から前記第2の位置まで前記移動部が移動する間に前記刃部によって前記光ファイバに傷をつけることが可能であり、
前記移動部が前記第2の位置にある場合において、
前記第2の磁石は前記第1の磁石と同極側が互いに向き合う位置であって、かつ、前記第1の磁石よりも前記第1の位置に近い側にある。
この構成によれば、第1の磁石および第2の磁石間の斥力によって移動部を第1の位置の方向へと移動させる力が生じ、簡単な構成で、光ファイバの切断後に刃部を有する移動部を初期位置付近まで自動で戻すことが可能である。
移動部が第2の位置にある場合に、第2の磁石と第1の磁石が移動部の移動方向において同位置にある、又は第2の磁石よりも第1の磁石の方が第1の位置に近い側にあると、移動部が第1の位置側へと動かない又は動かしにくく、例えば、移動部を手動で僅かに第1の位置側へと動かさなくてはならない。本開示では、移動部が第2の位置にある場合において、第2の磁石が第1の磁石よりも第1の位置に近い側にあるように構成しているので、そのような問題を生じさせず、移動部を初期位置まで移動させることが可能である。
前記本体は、さらに、磁性を有する金属を有し、
前記移動部が前記第1の位置にある場合において、前記磁性を有する金属は前記第2の磁石と互いに向き合う位置にあり、前記第2の磁石および前記磁性を有する金属間の引力によって前記移動部を前記第1の位置で停止させるように構成されていることが好ましい。
上記の構成によれば、第1の磁石および第2の磁石間の斥力によって移動部を第1の位置の方向へと移動させた後、移動部を第1の位置で停止させることができる。
また、例えば、磁性を有する金属の代わりに磁石を用いた場合、該磁石と第2の磁石間の引力が強くなって、第1の位置から第2の位置へと手動で移動させる際に要する力が大きくなることがある。その結果として、作業性が落ちたり、過度に大きな力を加えることで移動部が勢いよく動いてしまい、光ファイバに意図せぬダメージを与えたりするおそれがある。上記の構成では、磁石ではなくて磁性を有する金属を用いることで、上記のおそれを低減できる。
上記開示の構成によれば、簡単な構成で、光ファイバの切断後に刃部を有する移動部を初期位置付近まで自動で戻すことが可能である。
以下、本開示に係る実施の形態の例を、図面を参照しつつ説明する。なお、以下の説明では、異なる図面であっても同一又は相当の要素には同一の符号を付し、重複する説明を適宜省略する。また、以下の説明に用いる各図面では、各部材を認識可能な大きさとするために縮尺を適宜変更している。
