【従来の技術】[Prior Art]

近年の情報通信量の増大にともない、ファクシミリ、テレビ電話、双方向テレ ビなど、その使用が一部に限られていた各種情報通信機器が、一般家庭でも使用 され始め、ますます普及する傾向にある。 With the recent increase in the amount of information communication, various information communication devices such as facsimiles, videophones, and two-way televisions, whose use was limited to a part, have begun to be used in general households and are becoming more and more popular. is there.

【0003】 このような中で、光ファイバケーブルは、上記情報通信機器間を接続する通信 用配線として、その通信網に組み込まれて広く用いられている。Under such circumstances, the optical fiber cable is widely used by being incorporated in the communication network as a communication wiring for connecting the information communication devices.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、前述したように、近時、情報通信機器が一般家庭でも普及し始 めてきたことから、これらの通信用配線と電力引込み線とを複合化して配線の合 理化を図ろうという要求が生じている。 However, as mentioned above, since information and communication devices have recently begun to spread in general households, there is a demand to combine these communication wires and power service wires to rationalize the wiring. Has occurred.

【0007】 本発明はこのような要求に応えるべくなされたもので、光ファイバを電力引込 み線とそれぞれの特性を損なうことなく複合化してなる光ファイバ複合引込み用 電線を提供することを目的とする。The present invention has been made in order to meet such a demand, and an object thereof is to provide an optical fiber composite service wire in which an optical fiber is combined with a power service wire without impairing the respective characteristics. To do.

【課題を解決するための手段】[Means for Solving the Problems]

本考案の光ファイバ複合引込み用電線は、繊維強化複合材料からなる抗張力体 の外周面に長さ方向に沿って凹溝を設け、この凹溝に光ファイバ心線を撚込むと ともに、これらの外周に導体を添わせ、さらに、この外周に絶縁被覆を施してな ることを特徴とするものである。 The optical fiber composite lead-in wire of the present invention has a groove formed along the length direction on the outer peripheral surface of a strength member made of a fiber reinforced composite material, and the optical fiber core wire is twisted in the groove and these It is characterized in that a conductor is added to the outer periphery, and further an insulating coating is applied to the outer periphery.

【0009】 本考案の抗張力体を構成する繊維強化複合材料としては、たとえば、炭素繊維 強化プラスチックやガラス繊維強化プラスチック、あるいはポリアラミド繊維な どの高抗張力有機繊維を強化材とした有機繊維強化プラスチックなどがあげられ 、なかでも、エポキシ樹脂をマトリックスとした炭素繊維強化プラスチックが機 械特性、成形性の点から適している。このような繊維強化複合材料からなる抗張 力体は、軽量で、引張強度が大きく高弾性率であるうえに伸びが小さいという性 質を有しており、布設の際や通電時の導体の熱収縮などから、その外周面に設け た凹溝に撚込んだ光ファイバ心線を保護する。ちなみに、炭素繊維強化プラスチ ックの特性を、たとえば導体として汎用されている硬銅線と比較した場合、引張 り強度が 4〜5 倍、伸びは1/2 〜1/3 である。Examples of the fiber reinforced composite material constituting the tensile strength body of the present invention include carbon fiber reinforced plastics, glass fiber reinforced plastics, and organic fiber reinforced plastics obtained by reinforcing high tensile strength organic fibers such as polyaramid fibers. Among them, carbon fiber reinforced plastics containing epoxy resin as a matrix are suitable from the viewpoint of mechanical properties and moldability. A tensile body made of such a fiber-reinforced composite material is lightweight, has a high tensile strength, a high elastic modulus, and has a small elongation. Protects the optical fiber core twisted in the groove provided on the outer peripheral surface from heat shrinkage. By the way, when comparing the characteristics of carbon fiber reinforced plastics with, for example, hard copper wire that is commonly used as a conductor, the tensile strength is 4 to 5 times and the elongation is 1/2 to 1/3.

【0010】 なお、かかる抗張力体の外周面に設けられた凹溝に撚込む光ファイバ心線とし ては、単心構造、多心構造のいずれであってもよく、また、光ファイバを複数本 並列させ、その外周に所要の保護被覆を設けた構造の、いわゆる多心光ファイバ テープを用いることもできる。凹溝は、用いる光ファイバ心線の数や構造に合わ せて適宜形成される。The optical fiber core wire to be twisted in the groove provided on the outer peripheral surface of the tensile strength member may have a single-core structure or a multi-core structure, and a plurality of optical fibers may be used. It is also possible to use a so-called multi-core optical fiber tape which is arranged in parallel and has a required protective coating on its outer periphery. The concave groove is appropriately formed in accordance with the number and structure of optical fiber cores to be used.

【0011】 また、これらの外周に配置する導体としては、従来より電力引込み線用として 使用されている硬銅線やその撚線、軟銅線などが使用される。Further, as the conductors arranged on the outer periphery of these, a hard copper wire, a twisted wire thereof, an annealed copper wire or the like which has been conventionally used for a power lead wire is used.

【0012】 絶縁被覆も導体同様に、従来より電力引込み線用として使用されているPVC が適しているが、特にこのものに限定されるものではなく他の絶縁材料を用いる ようにしてもよい。Similarly to the conductor, PVC, which has been conventionally used for the power supply line, is suitable for the insulating coating, but the insulating coating is not particularly limited to this and other insulating materials may be used.

【0013】 さらに、本発明においては、この絶縁被覆の外周に、必要ならば、他の保護被 覆を設けるようにしてもよい。Further, in the present invention, another protective cover may be provided on the outer periphery of the insulating coating, if necessary.

【0014】[0014]

【作用】[Action]

本考案の光ファイバ複合引込み用電線では、軽量で、引張強度が極めて大きい うえに伸びが小さいという性質を備えた繊維強化複合材料からなる抗張力体を用 い、この外周面に長さ方向に沿って凹溝を設け、この凹溝に光ファイバ心線を撚 込むとともに、これらの外周に導体を添わせ、さらに、この外周に絶縁被覆を施 した構造からなるので、光ファイバが外力に対し十分に保護される結果、従来の 引込み線と同様に取り扱っても、また、通電時に導体が大きく熱収縮することが あっても光ファイバが損傷したり特性が低下するようなことはない。他方、引込 み線としての性能も十分確保されるため、これを引込み線として、電力供給の配 電網を布設する際に用いれば、同時に通信網も確保されることになり、その後の 通信量の増大に容易に対応することが可能となる。 The optical fiber composite lead-in wire of the present invention uses a strength member made of a fiber-reinforced composite material that is lightweight, has extremely high tensile strength, and has a small elongation, and its outer peripheral surface extends along the length direction. The optical fiber core wire is twisted into the groove, the conductor is added to the outer periphery of the optical fiber, and the outer periphery is insulated. As a result, the optical fiber will not be damaged or its characteristics will not be degraded even if it is handled in the same way as a conventional drop wire, or if the conductor undergoes a large thermal contraction when energized. On the other hand, since the performance as a service line is also sufficiently secured, if this is used as a service line when laying a distribution network for power supply, a communication network will be secured at the same time, and the communication volume after that will be increased. It becomes possible to easily cope with the increase.

On these, as conductor 4, six 2.0 mmφ hard copper wires are twisted together, and further, as the insulation coating 5, a PVC coating is extruded to have an outer diameter of 9.0 mm, for example. ing.

【0018】 このように構成された光ファイバ複合引込み用電線は、光ファイバ心線3が引 張強度が大きいうえに伸びが小さい繊維強化複合材料からなる抗張力体1により 外力から保護される一方、引込み線としての十分な特性を有していた。すなわち 、 JISに規定された引込み線規格を満足する電気特性、機械特性を有していた。In the optical fiber composite lead-in wire configured as described above, the optical fiber core wire 3 is protected from external force by the tensile strength body 1 made of a fiber reinforced composite material having a high tensile strength and a small elongation. It had sufficient characteristics as a service line. That is, it had electrical properties and mechanical properties that satisfied the service wire standard specified in JIS.
