Description

本発明は、光ファイバ・メタル複合ドロップケ−ブルに関するものである。 The present invention relates to an optical fiber / metal composite drop cable.

従来、各家庭には、電話用ケ−ブルとして、メタルケ−ブルであるオクソト線、オクウチ線等が引き込み柱から各家庭まで及び各家庭内に布設されているが、光ファイバケ−ブルを使用したインタ−ネットサ−ビスを利用する場合には、新たにドロップ光ケ−ブルを引き込み柱から各家庭まで及び各家庭内に布設しなければならなかったので、次のような問題があった。 Conventionally, in each home, metal cables such as oxto wires and ukuuchi wires are laid from the pull-in pillars to each home and in each home as optical cables, but optical fiber cables are used. When using the Internet service, a new drop optical cable has to be laid from the pull-in column to each home and in each home.

（１）住戸（特に戸建て住宅）の既設引き込み用管路は細く、その管路にドロップ光ケ−ブルを引き込む余裕がないので、ドロップ光ケ−ブル用の新たな管路を設置するか又は既に布設されたメタルケ−ブルを一旦管路から除去して、除去したメタルケ−ブルと新規なドロップ光ケ−ブルとを同時に既設管路に引き込まなければならなかった。
（２）引き込み柱から家庭までのル−トがメタルケ−ブルとドロップ光ケ−ブルとの２ル−トになり、景観を損なう。
（３）工事費が嵩み、工期が長くなる。 (1) Since the existing lead-in pipes for dwelling units (especially detached houses) are thin and there is no room for drawing the drop optical cable into the pipe, either install a new pipe for the drop optical cable or The already laid metal cable has to be removed from the pipeline, and the removed metal cable and the new drop optical cable must be simultaneously drawn into the existing pipeline.
(2) The route from the pull-in pillar to the home becomes two routes, a metal cable and a drop light cable, and the landscape is damaged.
(3) The construction cost increases and the construction period becomes longer.

この発明は、背景技術で記述した問題を解消するためになされたもので、布設工事の手間と工事費の節減が可能であり、かつ景観を損なわない光ファイバ・メタル複合ドロップ光ケ−ブルの提供を目的とするものである。 The present invention has been made to solve the problems described in the background art, and it is possible to reduce the labor and cost of laying work and to reduce the cost of the optical fiber / metal composite drop optical cable that does not impair the scenery. It is for the purpose of provision.

この発明の光ファイバ・メタル複合ドロップヶ−ブルは、支持線とテンションメンバを配設した光ファイバ素線とメタル対撚線とをそれぞれ略三角形の頂点部に位置するように配置し、前記支持線と前記メタル対撚線には、円状にシ−スを施し、前記テンションメンバを配設した光ファイバ素線には、該光ファイバ素線の左右にノッチを備え略ひょうたん状になるようにシ−スを施し、それぞれのシ−スを逆Ｙ字状のブリッジで橋絡一体化したことを特徴とするものである。 In the optical fiber / metal composite drop cable of the present invention, the support fiber, the optical fiber element having the tension member and the metal twisted pair are arranged so as to be positioned at the apex of the triangle, respectively. And the metal pair stranded wires are circularly sheathed, and the optical fiber strands provided with the tension members are provided with notches on the left and right sides of the optical fiber strands so as to have a substantially gourd shape. A sheath is applied, and the respective bridges are integrated with an inverted Y-shaped bridge.

この発明は上述のように構成されているので、次のような効果を奏する。
（１）支持線を引き裂くことによって、メタル対撚線部と光ケ−ブルの複合インドアケ−ブルとしてそのまま使用できる。
（２）さらに、メタル対撚線部のみを引き裂くことにより光ファイバは無切断にて、メタル対撚線部のみを切断、接続工事することができる。
（３）さらに、光ユニット部では、左右に設けたノッチを引き裂くことにより光ファイバ素線を容易に取り出すことができる。
（４）風圧荷重を低減できる。
（５）景観を損なわない。 Since the present invention is configured as described above, the following effects can be obtained.
(1) By tearing the support wire, it can be used as it is as a composite indoor cable of a metal pair twisted wire portion and an optical cable.
(2) Further, by tearing only the metal pair stranded portion, the optical fiber can be cut and connected by cutting only the metal pair stranded portion without cutting.
(3) Furthermore, in the optical unit part, the optical fiber can be easily taken out by tearing the notches provided on the left and right.
(4) Wind pressure load can be reduced.
(5) Does not damage the landscape.

布設工事の手間と工事費の節減が可能であり、かつ景観を損なわないという目的を、支持線とテンションメンバを配設した光ファイバ素線とメタル対撚線とをそれぞれ略三角形の頂点部に位置するように配置し、それぞれのシ−スを逆Ｙ字状のブリッジで橋絡一体化することにより実現できた。 The purpose of the construction work can be reduced and the construction cost can be reduced, and the objective of not damaging the landscape is to place the optical fiber strand and the metal twisted wire with the support wire and tension member at the apex of the triangle. This was realized by arranging the units so as to be located and integrating the respective bridges with an inverted Y-shaped bridge.

この発明の実施の一例を図面を参照しながら説明するに、図１〜図２に示すように、支持線１とテンションメンバ２を配設した光ファイバ素線３とメタル対撚線４とをそれぞれ略三角形の頂点部に位置するように配置している。 An example of the embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 2, an optical fiber strand 3 and a metal pair stranded wire 4 provided with a support wire 1 and a tension member 2 are provided. They are arranged so as to be located at the apexes of substantially triangular shapes.

支持線１とメタル対撚線４とは円状にシ−ス６を施し、テンションメンバ２を配設した光ファイバ素線３は左右にノッチ５を備えた略ひょうたん状になるようにシ−ス６’を施し、それぞれのシ−ス６，６’を逆Ｙ字状のブリッジ６”で橋絡一体化している。 The support wire 1 and the metal pair stranded wire 4 are provided with a circular sheath 6, and the optical fiber 3 provided with the tension member 2 is formed into a substantially gourd shape with notches 5 on the left and right. 6 'is applied, and the respective cases 6 and 6' are bridge-integrated by an inverted Y-shaped bridge 6 ".

シ−ス６，６’及びブリッジ６”は同一材質で、図示は省略した押出機によって、同時に一体的に押し出される。シ−ス６，６’及びブリッジ６”の材質は難燃ポリエチレンあるいはＰＶＣである。 The sheaths 6 and 6 'and the bridge 6 "are made of the same material and are simultaneously and integrally extruded by an unillustrated extruder. The materials of the sheaths 6 and 6' and the bridge 6" are made of flame-retardant polyethylene or PVC. It is.

テンションメンバ２としては、ガラスＦＲＰやケブラ−、ＰＥＴ紐などが適用され、テンションメンバ２が１本の場合には、図１に示すように、２本の場合には、図２に示すように配設される。 As the tension member 2, glass FRP, Kevlar, PET string, or the like is applied. As shown in FIG. 1, when the tension member 2 is one, as shown in FIG. Arranged.

なお、光ファイバ素線３は１本あるいは２本の場合があり、また光ファイバ２心テ−プあるいは４心テ−プであってもよい。また、メタル対撚線部は対撚でなく、メタル心線が２本であってもよい。 The optical fiber 3 may be one or two, and may be a two-fiber tape or a four-fiber tape. Moreover, a metal pair twisted wire part may not be a pair twist, but two metal core wires may be sufficient.

将来、光ファイバケ−ブルの布設が見込まれる新築ビル、マンション用の情報ケ−ブルとしても利用が可能である。 It can also be used as an information cable for new buildings and condominiums where the installation of optical fiber cables is expected in the future.
