Description

【発明の詳細な説明】 〔技術分野〕 本発明は自己支持型だるま形架空用ケーブル管路に係わ
る。DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a self-supporting potbell-shaped overhead cable conduit.

〔発明の目的および（１４１戊１ 現任、電話加入者用ケーブルには、自己支持型架空用ケ
ーブルとしてだろ首形ケーブルが広く使用されている。[Purpose of the Invention and (141 戊1) Presently, dovetail cables are widely used as self-supporting aerial cables for telephone subscriber cables.

だるま形ケーブルは架線が容易でアセ、坤込者−へ−の
分岐・引込みにも都合がよい。The potbell-shaped cable is easy to connect, and is convenient for branching and pulling in to users.

しかし、導体サイズ、対数が増加するにつれてケーブル
の自重は増加し、同時にテンションメンバーのサイズも
増加するなど、風によるダンシングの問題等と合わせて
、架線できるものには″大きさに限度がある。However, as the conductor size and number of logarithms increase, the weight of the cable increases, and at the same time the size of the tension member also increases.This, combined with the problem of dancing due to the wind, places a limit on the size of the cable that can be used.

も、外観的に一本のケーブルであり、極めて好しい。By the way, with the progress of communication systems using optical cables,
It is clear that subscriber cables will shift from copper cables to optical cables sooner or later, but once they have been installed, even if the number of subscribers increases or decreases, it will be easy to pull in the regular round optical cables. By removing it, you can freely select the number of fibers of the optical cable with a single cable conduit in appearance, which is not only advantageous in terms of system costs, but also in terms of aesthetics and appearance. cable, which is extremely preferable.

本発明はこのような観点によりなされた自己支持型だる
ま形架空用ケーブル管路に係わる。The present invention relates to a self-supporting pot-shaped aerial cable conduit made from this viewpoint.

以下実施例について説明する。Examples will be described below.

図は本発明による自己支持型だるま形架空用ケーブル管
路を一部欠截しで示す。The figure shows, partially cut away, a self-supporting pot-shaped overhead cable conduit according to the invention.

である。A plurality of pipes, for example, four pipes, are bundled in a straight line, and after being tightly wound with loose winding thread 4, etc., this is made into a core, and tension members 1 are spaced apart and 1 longitudinally attached, and a generally known plastic is used. By extrusion, external waves 3 are integrally applied so that the cross section becomes a sag. Note that 5 is the neck.

〔効果Ｊ 本発明によるケーブル管路は従来の自己支持型だるま形
ケーブルと外観構造等は同じであり、従来の工法と略同

メンバー１と管路４の部分との分篩が容易であり、電柱
等に引留めやすい。[Effect J The cable conduit according to the present invention has the same external structure as the conventional self-supporting potbell-shaped cable, and can be wired using substantially the same construction method as the conventional construction method, and the tension member 1 and the conduit It is easy to separate it from part 4, and it is easy to attach it to utility poles, etc.

また、管路ザイズ、本数、形状など自由に選択でき、管
路が独立しているので、分岐が自由であり、管路側面に
孔をあければ丸形の光ケーブルが取シ出される。In addition, the size, number, and shape of the pipes can be freely selected, and since the pipes are independent, they can be branched freely, and a round optical cable can be taken out by drilling a hole in the side of the pipe.

更に自己支持型だるま形ケーブルについては従来の実績

が得られる。Furthermore, the strength of self-supporting pot-shaped cables (wind dancing, overhead wire tension) is well understood based on previous experience, so this can be used as a reference, and production line equipment, jigs, etc. It is possible to obtain a cable conduit that is sufficiently reliable in terms of quality and has no technical problems.

その使用については、前述のような光ケーブルの外にも
軽量な通信ケーブル、電カケーブル等軽量なケーブルで
あれば、必要により引込み、撤去することにより使用す
ることができる。Regarding its use, in addition to the above-mentioned optical cable, any lightweight cable such as a lightweight communication cable or electric power cable can be used by pulling it in and removing it as necessary.
