本考案は光伝送路を１つの伝送路から別の伝送路へ光学
的に低損失で安定に切替を行う光伝送路切替器に関する
ものである。[Detailed Description of the Invention] The present invention relates to an optical transmission line switching device that optically switches an optical transmission line from one transmission line to another optically with low loss.
従来、この種の光伝送路切替器として例えば第１図に示
すようなものがある。Conventionally, there is a type of optical transmission line switching device as shown in FIG. 1, for example.
第１図において、１′は保護部材で保護された光ファイ
バ１の端末部、２′は保護部材で保護された光ファイバ
２の端末部、３は複数本の光ファイバ１の端末部１′を
保持する固定板、４は光ファイバ２の端末部２′を保持
しシャフト７に固定された回転板、５は固定板３と回転
板４との間の間隔を一定に保つ間隔円板、６は接続位置
を示すための表示板であり、シャフト７を回転させるこ
とにより他の光ファイバ１に対する光ファイバ２の光学
的接続をとり光伝送路の切替を行うようになっている。In FIG. 1, 1' is an end portion of an optical fiber 1 protected by a protection member, 2' is an end portion of an optical fiber 2 protected by a protection member, and 3 is an end portion 1' of a plurality of optical fibers 1. 4 is a rotating plate that holds the end portion 2' of the optical fiber 2 and is fixed to the shaft 7; 5 is a spacing disk that maintains a constant distance between the fixed plate 3 and the rotating plate 4; Reference numeral 6 denotes a display plate for indicating the connection position, and by rotating the shaft 7, the optical fiber 2 is optically connected to another optical fiber 1 and the optical transmission path is switched.
この機械的切替器では光ファイバ２の端末部２′を保持
する回転板４を回転させる構成となっているので、回転
板４のぶれが生じ易く回転板４の周辺部の光ファイバ２
の端末部２′の固定板３に対する距離が変化し易い。Since this mechanical switch is configured to rotate the rotary plate 4 that holds the end portion 2' of the optical fiber 2, the rotary plate 4 is likely to shake, and the optical fiber 2 at the peripheral portion of the rotary plate 4 may
The distance between the terminal portion 2' and the fixing plate 3 is likely to change.
従って、伝送路を切替えた場ａに互いに対向する光フア
イバ端末部間の間隔を一定に保つことは困難で光学的接
続損失の再現性が得られず不安定である。Therefore, when the transmission path is switched, it is difficult to maintain a constant distance between the mutually opposing optical fiber terminals, and the optical connection loss cannot be reproducibly obtained, resulting in instability.
オた回転板４が回転するため光ファイバ２が捻れたりし
て端末部間の間隔が一定にならない。Since the rotation plate 4 rotates, the optical fiber 2 may be twisted, and the distance between the end portions may not be constant.
昔た、回転機構のため部品側々の工作精度を上げる必要
があり部品点数も多いため高価となるという欠点がある
。In the past, due to the rotating mechanism, it was necessary to improve the machining accuracy of each part, and the number of parts was large, making it expensive.
本考案の目的は上述のごとき欠点を除去した光伝送路切
替器を提供することにある。An object of the present invention is to provide an optical transmission line switch that eliminates the above-mentioned drawbacks.
次に本考案の実施例について図面を参照して説明する。Next, embodiments of the present invention will be described with reference to the drawings.
本考案の一実施例を示した第２図にも・いて、１′は金
属、プラスチック等により保護された光ファイバ１の端
末部で、該端末部１′が２個並列に配置されて光フアイ
バ分配部を構成する。In FIG. 2, which shows an embodiment of the present invention, 1' is a terminal part of an optical fiber 1 protected by metal, plastic, etc., and two terminal parts 1' are arranged in parallel to emit light. This constitutes a fiber distribution section.
２′は同様に金属、プラスチック等により保護された光
ファイバ２の端末部で、その端面が２個の端末部１′の
各端面に対向するように可動となっているものである。2' is a terminal portion of the optical fiber 2 which is similarly protected by metal, plastic, etc., and is movable so that its end surface faces each end surface of the two terminal portions 1'.
８は上記光フアイバ分配部の２個の端末部１′に対する
可動端末部２′の対向位置における互いの端面間隔を一
定に保つための板バネ、９は２個の端末部１′に対する
可動端末部２′の対向位置における互いＱ光軸をゴ致さ

２′を動かすためのロッド、１１は端末部２′を上記光
フアイバ分配部の上方の端末部１′に対向するように切

すスプリング、１２はスプリング１１を固定するための
ブラケット、１３は端末部２′を上方の端末部１′に対
向するように切替えるための電磁石である。Reference numeral 8 denotes a leaf spring for maintaining a constant distance between the end faces of the movable end portion 2' with respect to the two end portions 1' of the optical fiber distributing section, and 9 represents a movable end with respect to the two end portions 1'. A case having a V-shaped groove 9' for aligning the Q optical axes at opposing positions of the parts 2', 10 a rod for moving the end part 2', and 11 a rod for moving the end part 2' to the above-mentioned optical fiber distribution part. A spring which is switched to face the upper terminal part 1' and then returns to its original position facing the lower terminal part 1', 12 is a bracket for fixing the spring 11, and 13 is a spring for fixing the terminal part 2'. This is an electromagnet for switching so as to face the upper terminal portion 1'.
この切替器を動作させるには電磁石１３に電流を流すこ
とによって電磁石１３に設けられたリンク１４によりロ
ッド５が上方に押され可動端末部２′は反対側のＶ字形
溝９′に押し付けられ上記光フアイバ分配部の上方の端
末部１′に対向する位置に移動させられる。To operate this switch, an electric current is applied to the electromagnet 13 so that the rod 5 is pushed upward by the link 14 provided on the electromagnet 13, and the movable end 2' is pressed against the V-shaped groove 9' on the opposite side. It is moved to a position above the optical fiber distribution section, opposite the terminal section 1'.
この状態を第２図ａに１点鎖線で示す。This state is shown in FIG. 2a by a dashed line.
渣た電磁石１３の電流を切ることによってスプリング１
１の反発力で可動端末部２′はもとのＶ字形溝９′に押
し付けられもとの位置にもどる。By cutting off the current of the residual electromagnet 13, the spring 1
With a repulsive force of 1, the movable end portion 2' is pressed against the original V-shaped groove 9' and returns to its original position.
可動端末部２′はロッド１０の運動と平行な方向に可動
となるように板バネ８の一端に固定されているため、ロ
ッド１０の運動と直交する平面内の第２図ｂＫ＄−ける
左右方向での動きは非常に少ない。Since the movable end portion 2' is fixed to one end of the leaf spring 8 so as to be movable in a direction parallel to the movement of the rod 10, the movable end portion 2' is fixed to one end of the leaf spring 8 so as to be movable in a direction parallel to the movement of the rod 10. There is very little movement in the direction.
斗た上記光フアイバ分配部の２個の端末部１′と可動端
末部２′との対向位置に釦ける互いの端面間隔は板バネ
８の他端を可動端末部２′の可動範囲の中心となるよう
にケース９に固定することにより一定に保たれる。The distance between the end faces of the two end portions 1' and the movable end portion 2' of the optical fiber distribution section is such that the other end of the leaf spring 8 is the center of the movable range of the movable end portion 2'. It is kept constant by fixing it to the case 9 so that.
よって光フアイバ同志の光学的接続が安定して行われる
ため光学的接続損失の再現性が非常に良くなる。Therefore, the optical connection between the optical fibers is stably performed, and the reproducibility of the optical connection loss is extremely improved.
第３図に本考案の他の実施例を示す。FIG. 3 shows another embodiment of the present invention.
第３図に卦いて第２図と同じ部分は同一参照符号にて示
しである。The same parts in FIG. 3 as in FIG. 2 are designated by the same reference numerals.
この実施例は板バネ８を２つ用いて可動端末部２′を保
持した構造を特徴とするものである。This embodiment is characterized by a structure in which two leaf springs 8 are used to hold the movable end portion 2'.
以上説明したように本考案によれば板バネの円弧運動を
利用して互に対向する光ファイバ端末都市し端面間隔を
一定に保持する構造であるから従来の回転式等と比較し
て部品の工作精度を上げることなくまた少ない部品点数
で安価な安定した光伝送路切替器を得ることができる。As explained above, according to the present invention, the arcuate motion of the leaf spring is used to connect the optical fiber terminals facing each other and maintain a constant distance between the end faces. It is possible to obtain an inexpensive and stable optical transmission line switching device with a small number of parts without increasing the machining accuracy.
