Description
【発明の詳細な説明】 〔発明の技術分野〕 本発明は光フアイバケーブル端末部に係る。[Detailed description of the invention] [Technical field of invention] The present invention relates to an optical fiber cable terminal.
光フアイバケーブルを使用したシステムは第１図に示す
ように構成されている。すな、わち、光フアイバケーブ

続している。この接続部はスプライスボックス５によっ
て保護されている。A system using optical fiber cables is constructed as shown in FIG. That is, Elo and 0/E converters 2 are arranged at both ends of the optical fiber cable 10, and a single-core cord 4 is connected to the converter 2 via a connector 3.
is connected to one of the optical fibers 1a in the optical fiber cable 1. This connection is protected by a splice box 5.

あった。これらの事情により工事費がかさみ、システム
の価格が高くなる欠点があった。During installation, the optical fiber cable 1, single-core cord 4 with connector 3, O/E, E10 converter 2, and splice box 5 are transported to the site, and they are combined at the site.
The system shown in the figure is used. The most problematic issue in this case is the connection between the single-core cord 4 and the optical fiber 1a. Since this connection is normally made by heat fusion using electrical discharge or the like, it is not only necessary to have a connection technician travel to the site, but also to transport the connection device to the site. Furthermore, it was necessary to provide a splice box to protect the connections. These circumstances have the drawback of increasing construction costs and increasing the price of the system.
なお、コネクタの取付けられる単心コードを撚合わせて
光フアイバケーブルを構成すれば、光ファイバと単心コ
ードの接続作業を省（ことができるが、ケーブル価格が
高（なり、長尺の場合には第１図に示した従来のシステ
ムより高価となる。Note that if you construct an optical fiber cable by twisting the single-core cords to which the connector is attached, you can save the work of connecting the optical fibers and the single-core cord, but the cable price will be high (and if the cable is long) is more expensive than the conventional system shown in FIG.
本発明は上記の事情に基きなされたもので、布設現場に
おける単心コードと光ファイバとの接続作業を必要とせ
ず、しかも低価格で供給し得る光フアイバケーブルを得
ることを目的としている。The present invention has been made based on the above-mentioned circumstances, and aims to provide an optical fiber cable that does not require connection work between a single-core cord and an optical fiber at the installation site and can be supplied at a low price.
本発明においては、光フアイバケーブル端末に保護カバ

る。In the present invention, a protective cover is provided at the end of the optical fiber cable, an optical fiber and a single-core cord with a connector are connected within this protective cover, and a pulling eye that is continuous with the tension member of the optical fiber cable is provided at the tip of the protective cover. The above object is achieved by providing a flexible cheep that surrounds the single-core cord protruding from the protective cover.
第２図において、光フアイバケーブル１の端末には、剛
性材料から成る円筒状の保護カバー６が取付けである。In FIG. 2, a cylindrical protective cover 6 made of a rigid material is attached to the end of the optical fiber cable 1.

完成することができる。As described above, according to the present invention, a system can be completed without connecting optical fibers and single-core cords on site.
光ファイバと単心コードとの接続を必要としないので、
布設現場への接続技能者の出張、接続装置の運搬は不要
となり工事費が大巾に削減されるので、システムの価格
を低下させることができる。No connection between optical fiber and single-core cord is required, so
Since there is no need for a connection technician to travel to the installation site or to transport the connection equipment, construction costs are greatly reduced, and the price of the system can be lowered.
