本発明は光フアィバを収納した複合ケーブルの製造方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a composite cable containing optical fibers.
電気ケーブル内に情報伝達用としての光フアィバを収納
した複合ケーブルが近年使用されつつある。In recent years, composite cables in which optical fibers for information transmission are housed within electrical cables have been used.
しかし光ファイバーは強度的にも伝送特性的にも張力及
び張力等に伴って生ずる側圧を極端に嫌うため、複合ケ
ーブルが張力や熱膨張によって伸びても光フアィバには
極力張力が加わらないような製造方法を採用する必要が
ある。光フアィバを単にケーブルの中に撚り込むような
製造方法ではケーブル長さに対する光フアィバの余長率
を大きくすることはできず、ケーブルに大きな伸びが生
じた場合は光フアィバにも大きな張力がかかってしまう
ことになる。However, in terms of strength and transmission characteristics, optical fibers are extremely sensitive to tension and the lateral pressure that occurs due to tension, so even if the composite cable is stretched by tension or thermal expansion, it is manufactured so that as little tension as possible is applied to the optical fiber. method needs to be adopted. Manufacturing methods in which optical fibers are simply twisted into cables do not allow for a large ratio of excess optical fiber length to the cable length, and if a large amount of cable elongates, a large amount of tension will be applied to the optical fibers. This will result in
本発明の目的は、ケーブルが伸びても光フアィバには大
きな張力が加わらない複合ケーブルの製造方法を提供す
ることにある。An object of the present invention is to provide a method for manufacturing a composite cable in which no large tension is applied to the optical fiber even when the cable is stretched.

る。The gist of the present invention is to twist optical fibers around a core body to form or after forming an optical fiber strand, untwist it to a certain extent, or after untwisting it, store it in a pipe-shaped object, Thereafter, the optical fiber strand containing pipe-like object is assembled together with other cable elements.
また、光フアィバまたは芯体にねじり応力を残留させな
いために、光フアィバを芯体のまわりに撚り合わせる前
に予め光フアィバまたは芯体をねじっておいてもよい。Further, in order to prevent residual torsional stress in the optical fiber or the core, the optical fiber or the core may be twisted in advance before twisting the optical fiber around the core.
本発明の構成を、実施例を示す図面を参照して具体的に
説明する。第１図において、第１工程として芯体２の周
囲に光フアィバ１を巻回する。The configuration of the present invention will be specifically explained with reference to drawings showing embodiments. In FIG. 1, as a first step, an optical fiber 1 is wound around a core body 2.
３は光ファイバーを巻回された芯体２すなわち複合体で
あり、４は芯体送り出し用ボビン、５は光フアィバ送り
出し用ボビン、６は複合体用ボビンである。Reference numeral 3 designates a core body 2, ie, a composite body, around which an optical fiber is wound; 4, a bobbin for sending out the core body; 5, a bobbin for sending out the optical fiber; and 6, a bobbin for the composite body.
このとき、光フアィバ送り出し用ボビン５は自転させな
がら芯体２の周囲を公転させてもよい。At this time, the optical fiber feeding bobbin 5 may revolve around the core body 2 while rotating on its own axis.
第２工程として、第２図に示すように複合体用ボビン６
から複合体３を引き出しパイプ７に収納するに、複合体
用ボビン６を回転して、複合体３を撚りもどし笑いを生

図に示すように、電線８と共に撚り合わせ複合ケーブル
を製造する。As a second step, as shown in FIG.
When the composite body 3 is pulled out and stored in the pipe 7, the composite body bobbin 6 is rotated to untwist the composite body 3 and make it laugh. Such a pipe 7 is used as a third process.
As shown in the figure, a stranded composite cable is manufactured together with the electric wires 8.
第４図は第１工程の変形例を示すもので、光ファイバー
を芯体２に巻回すると共に複合体用ボビン６を撚りもど
す向きに回転するものである。FIG. 4 shows a modification of the first step, in which the optical fiber is wound around the core 2 and the composite bobbin 6 is rotated in the untwisting direction.
９は中間に設けられた固定装置であり、光フアィバ１と
芯体２とを適宜間隔毎に固定するためのものであり、１
０は固定部を示す。9 is a fixing device provided in the middle for fixing the optical fiber 1 and the core body 2 at appropriate intervals;
0 indicates a fixed part.
このように光フアィバ１の撚り合わせと撚りもどしが同
時に行われた場合には、第２工程では複合体をパイプ７
内に収納すればよく撚りもどしは必要ない。When the optical fibers 1 are twisted and untwisted at the same time, the composite is transferred to the pipe 7 in the second step.
If you store it inside, there is no need to untwist it.
さらにまた別の変形例として、光フアィバを芯体に撚り

らいずれかの工程は同時に行なう方が望ましい。As yet another modification, a first step of twisting the optical fiber onto a core body, a second step of untwisting, a third step of storing the composite in a pipe, and a fourth step of twisting the pipe and electric wire. Although they can be performed separately, it is preferable to perform both processes simultaneously from the viewpoint of production efficiency.

合体３をずれ防止物体成形装置１１に通して、ずれ防止
物体１２を取付け、パイプ成形装置１３により成形され
たパイプ７内に連続的に収納するものである。FIG. 5 is an example of a process subsequent to the process shown in FIG. It is to be stored continuously inside.
ずれ防止物体１２が取付けられるときは、固定部１０の
必要性はあまりなく、省略してもよい。When the anti-slip object 12 is attached, the fixing part 10 is not really necessary and may be omitted.
固定部１０を省略して、ずれ防止物体１２を敬付けた場
合の構造例を第６図に示す。以上、述べたような方法で
製造した複合ケープルでは、光フアィバ及び芯体にねじ
り応力が残留するのが一般である。FIG. 6 shows a structural example in which the fixing part 10 is omitted and the anti-slip object 12 is attached. In the composite cable manufactured by the method described above, torsional stress generally remains in the optical fiber and the core.
残留ねじり応力を少なくするためには光フアィバ及び芯
体を予めねじっておくことが有効である。In order to reduce residual torsional stress, it is effective to twist the optical fiber and the core in advance.
予めねじる方向およびその量は以後の撚り合せ状況によ
り異なる。The direction and amount of pre-twisting differs depending on the subsequent twisting situation.
光フアィバを収納したパイプと電線との位置関係は適宜

｛１１ 光フアィバ管に収納されており、電線を撚り合
わせるだけなので容易に電線と光フアィバとの一体化が
できＬ格別の懸吊具などを要さず布設が簡便である。{11 Since it is housed in an optical fiber tube and the electric wires are simply twisted together, the electric wire and optical fiber can be easily integrated, and installation is simple without the need for special hanging tools.
