Description
【発明の詳細な説明】
（発明が解決しようとする問題点）
電カケーブルあるいは通信ケーブルと光ファイバとの複
合ケーブルからなるケーブル線路は公知である。DETAILED DESCRIPTION OF THE INVENTION (Problems to be Solved by the Invention) Cable lines consisting of composite cables of electric power cables or communication cables and optical fibers are known.
ところで、布設時はケーブルだけでよいが、将来、光フ
ァイバ等が必要になるかもしれないという場合に、初め
から、光・ケーブルの複合ケーブルを布設しておくのは
、不経済であるばかりでなく、保守上の点からも好まし
くない。By the way, it is sufficient to use only cables at the time of installation, but if optical fibers, etc. may be required in the future, it would be uneconomical to install a composite optical/cable cable from the beginning. This is not desirable from a maintenance point of view.
（発明の目的）
この発明は、最初はケーブルのみを布設しておき、後で
必要になってときには、容易に光ファイバ等を追加でき
るケーブル線路の提供を１的とするものである。(Objective of the Invention) One object of the present invention is to provide a cable line in which only a cable is laid at first, and an optical fiber or the like can be easily added later if necessary.
（実施例）
コアで、１６はその導体、１８は絶縁体、２０はしやへ
い層である。(Example) In the core, 16 is its conductor, 18 is an insulator, and 20 is a thin layer.
２２は可とう性のある金属あるいはプラスチック等から
なる中空パイプで、製造時には内部に何も挿入されてい
ない。22 is a hollow pipe made of flexible metal or plastic, and nothing is inserted inside it during manufacture.
この中空パイプ２２は、将来、光ファイバ等を入れるた
めのもので、摩擦抵抗を小さくするため、内面に潤滑油
を塗布するか、あるいは内部表面に長さ方向に複数条の
細い溝を形成したもの等が望ましい。This hollow pipe 22 is intended to be used to insert optical fibers in the future, and in order to reduce frictional resistance, the inner surface is coated with lubricating oil or multiple thin grooves are formed in the length direction on the inner surface. Preferably something like that.
なお、２４は介在、２６はシースである。In addition, 24 is an interposition, and 26 is a sheath.
第２図は４心同軸ケーブルの場合を示しており、３２は
同軸ケーブル線路の全体、４０は同軸心で、内部導体３
４、絶縁体３６、外部導体３８からなる。Figure 2 shows the case of a 4-core coaxial cable, where 32 is the entire coaxial cable line, 40 is the coaxial core, and the inner conductor 3
4, an insulator 36, and an outer conductor 38.
４２は第１図の２２と同様の中空のパイプである。なお
、４４はシースである。42 is a hollow pipe similar to 22 in FIG. Note that 44 is a sheath.
（発明の効果）
ケーブル線路には中空パイプが収納されており、この中
空パイプには何も挿入されていないので、ケーブルのみ
使用する場合は、このまま布設して使用することができ
る。(Effects of the Invention) A hollow pipe is housed in the cable line, and nothing is inserted into the hollow pipe, so when only the cable is used, it can be laid and used as is.
そして将来光ケーブル等が必要になったときには、ケー
ブル線路は布設したままで、その中空パイプ内に光ファ
イバ等を挿入することができる。When an optical cable or the like becomes necessary in the future, an optical fiber or the like can be inserted into the hollow pipe while the cable line remains installed.
したがって、光ファイバ等を必要なときのみに布設する
ことが可能なので、経済的であり、またその布設工事も
簡単である。Therefore, it is possible to install optical fibers only when necessary, which is economical, and the installation work is also simple.
