次に、従来技術による光カプラの構成を図３により説明する。図３の１〜３は 光ファイバ、６Ａ〜６Ｃは光コネクタ、７は光ファイバ溶融形の光カプラである 。光カプラ７の端部７Ａに光ファイバ１が接続され、光カプラ７の端部７Ｂに光 ファイバ２・３が接続される。光ファイバ１の先端には光コネクタ６Ａが取り付 けられ、光ファイバ２・３の先端には光コネクタ６Ｂ・６Ｃがそれぞれ取り付け られる。光カプラ７の端部７Ａ・７Ｂ間の寸法は例えば８cm程度である。 Next, the configuration of the optical coupler according to the conventional technique will be described with reference to FIG. In FIG. 3, 1 to 3 are optical fibers, 6A to 6C are optical connectors, and 7 is an optical fiber fusion type optical coupler. The optical fiber 1 is connected to the end 7A of the optical coupler 7, and the optical fibers 2 and 3 are connected to the end 7B of the optical coupler 7. An optical connector 6A is attached to the tip of the optical fiber 1, and optical connectors 6B and 6C are attached to the tips of the optical fibers 2 and 3, respectively. The dimension between the ends 7A and 7B of the optical coupler 7 is, for example, about 8 cm.
【０００３】 次に、図３の光カプラ７を巻き取るドラムを図４により説明する。図４の５は ドラム、５Ａと５Ｂはフランジである。例えば、ドラム５の真径が３cm、フラン ジ５Ａ・５Ｂの直径が５cm程度である。Next, a drum for winding the optical coupler 7 shown in FIG. 3 will be described with reference to FIG. In FIG. 4, 5 is a drum, and 5A and 5B are flanges. For example, the true diameter of the drum 5 is 3 cm, and the diameter of the flanges 5A and 5B is about 5 cm.
【０００４】[0004]
図３の光カプラ７を図４のドラム５に巻き取ろうとすると、光カプラ７の外形 が直方体なので、ドラム５に密接した形で巻き取ることができない。この考案は 、光カプラをドラム５の巻取位置の曲面と同じ曲面で形成することにより、ドラ ム５に密接した形で巻き取る光カプラの提供を目的とする。 When the optical coupler 7 of FIG. 3 is to be wound on the drum 5 of FIG. 4, the optical coupler 7 has a rectangular parallelepiped outer shape, so that the optical coupler 7 cannot be wound in a close contact with the drum 5. It is an object of the present invention to provide an optical coupler which winds in a form close to the drum 5 by forming the optical coupler with the same curved surface as the winding position of the drum 5.

この目的を達成するため、この考案では、光ファイバ１が端部４Ａに接続され 、光ファイバ２と光ファイバ３が端部４Ｂに接続される光ファイバ溶融形の光カ プラ４の外形をドラム５の巻取位置の曲面と同じ曲面で形成する。 In order to achieve this object, in the present invention, the outer shape of the optical fiber fusion type optical coupler 4 in which the optical fiber 1 is connected to the end 4A and the optical fibers 2 and 3 are connected to the end 4B is used. It is formed with the same curved surface as the curved surface of the winding position of No. 5.

次に、この考案による光カプラの構成を図１により説明する。図１の４は光フ ァイバ溶融形の光カプラであり、その他は図３と同じものである。光カプラ４の 端部４Ａに光ファイバ１が接続され、光カプラ４の端部４Ｂに光ファイバ２・３ が接続される。光カプラ４の外形はドラム５の巻取位置の曲面と同じ曲面で形成 される。 Next, the structure of the optical coupler according to the present invention will be described with reference to FIG. Reference numeral 4 in FIG. 1 denotes an optical fiber fusion type optical coupler, and other components are the same as those in FIG. The optical fiber 1 is connected to the end 4A of the optical coupler 4, and the optical fibers 2 and 3 are connected to the end 4B of the optical coupler 4. The outer shape of the optical coupler 4 is the same curved surface as the winding position of the drum 5.
【０００７】 次に、図１の光カプラ４を図４のドラム５に巻き取った状態を図２により説明 する。光カプラ４はドラム５の巻取位置の曲面と同じ曲面で形成しているので、 光ファイバ１〜３とともにドラム５に密接して巻き取られる。例えば、フランジ ５Ａ・５Ｂの直径が５cmの場合、図２の光カプラ４の巻取位置はフランジ５Ａ・ ５Ｂと同じ半径なので、光カプラ４を半径５cmの曲面で形成する。Next, a state in which the optical coupler 4 of FIG. 1 is wound around the drum 5 of FIG. 4 will be described with reference to FIG. Since the optical coupler 4 is formed with the same curved surface as the winding position of the drum 5, the optical coupler 4 is closely wound on the drum 5 together with the optical fibers 1 to 3. For example, when the diameter of the flanges 5A and 5B is 5 cm, the winding position of the optical coupler 4 in FIG. 2 is the same radius as the flanges 5A and 5B, so the optical coupler 4 is formed by a curved surface having a radius of 5 cm.
