線/通信線複合ケーブルが形成されている。(Prior Art) FIG. 1 is a cross-sectional view of an example of a power line/communication line composite cable. In the figure, 0) is a power line having an insulating layer (12) such as a cross-linked polyethylene insulating layer on the conductor (II) and an outer covering layer 03) of polyvinyl chloride or the like on the outside;
) is a communication line such as a communication cable, coaxial cable, optical cable, etc., in which the power line (3 to 4 cores and 1 to multiple cores of the communication line) are twisted together in a circle with an inclusion (3), and on the twisted A pressure tape (4) and a sheath (5) are applied to form a power line/communication line composite cable.

連長のケーブルを得ていた。Generally, in the production of long electric cables, the cable core twisting process consists of twisting cable cores of a certain length due to manufacturing equipment limitations (drum winding volume, total weight, etc.), and then twisting the cable cores to create a drum-wrapped number of cables. The lots were connected in a post-process to create a series of long cables. For example, when manufacturing an electric cable with a total length of 10 mm,
In the post-process, the conductor, insulator, and outer coating layer are connected to each of the 5 drum-wound cables, which take 3 to 4 days/1 day, and are twisted in a 10k series. I was getting a long cable.
第1図のような電力線/通信線複合ケーブルの場合も、
通信線(2)そのものは細径であり、軽量であるため、
製造設備上は十分に長尺で製造出来るにもかかわらず、
上述の如き電力線の設備上の制限から数ロットに分けて

様に接続して一連長の複合ケーブルにしていた。In the case of a power line/communication line composite cable as shown in Figure 1,
The communication line (2) itself has a small diameter and is lightweight, so
Despite the fact that the manufacturing equipment allows for sufficiently long lengths,
Due to the above-mentioned power line equipment limitations, they were manufactured in several lots, twisted together, and then connected in the same way as power cables in a subsequent process to form a continuous length of composite cable.

) (401!I) and pull out the end of the composite cable (401!I).
^) Untwist (406), connect the power line (4I) and the communication line (42), and then,
Twisting is performed again to create a composite regular cable, which is then wound around one of the drums. By repeating this process, long composite cables were manufactured.
(解決しようとする問題点)
上述したように従来の製造方法では、後工程で電力線と
通信線をそれぞれ接続することになる。(Problems to be Solved) As described above, in the conventional manufacturing method, the power line and the communication line are connected in a subsequent process.

造できるものを、電力線の都合上、止むなく数ロットで
製造し接続することになるので、品質上も、製造工程面
でも決して効率的な方法とはいえなかった。Although it is unavoidable to connect power lines due to limitations in manufacturing equipment, communication lines that can be manufactured in long lengths are unavoidably manufactured in several lots and connected due to the power lines. Therefore, it could not be said to be an efficient method in terms of quality or manufacturing process.

機械力を受けるので、これらに耐えろる様な性能をもっ

の開発と十分なる検証実験が必要となる。Furthermore, when optical cables are used for complex communication lines, the connection method is difficult, especially in the case of submarine cables, which are subjected to severe mechanical forces such as pulling, bending, and twisting during the process from manufacturing to installation. It is necessary to develop connections with durable performance, which requires the development of highly reliable connection methods and sufficient verification experiments.
さらに、電力線や通信線を接続した接続部は、撚合せ後
の外径が通常のケーブル部に比べると非常に大きくなり
、 Elの不連続点となって弱点が出来ることになり、
通信線の接続部の設計上及び製造上特に十分な配慮が必
要となる。Furthermore, the outer diameter of the joints where power lines and communication lines are connected is much larger after twisting than that of normal cable parts, and this results in points of discontinuity in El, creating weak points.
Particular consideration must be given to the design and manufacturing of communication line connections.

This provides a method for manufacturing a communication line composite cable.The feature is that in the process of twisting multiple cores of power lines and communication lines, the temporarily connected power line and a continuous length of communication line without a connection part are twisted together to form a long length. After that, the power lines and communication lines are untwisted near the temporary connection part of the power lines while being rewound onto another drum to make a regular connection of the power lines, and then the untwisted parts are twisted together. be.

fl The three cores of the line of force (IA) and the communication line (2), which is a continuous length and has no connection part and is wound around the drum, are twisted by the rotation of the twisting machine. The composite cables (22) are twisted to form a composite cable (22) and wound to a predetermined length on a winding drum (23).

The drum on which the #1 lot power line (IB) is wound is mounted, and the end of the twisting of the #1 lot power line (IA) and the beginning of the twisting of the #20 lot power line (IB) are temporarily connected (30 ) to form a continuous length and twist together with the communication wire (2) to form a composite cable (22). In this way, the power line (+
) by temporarily connecting several lots of power lines (2).
A long composite cable (22) will be manufactured.
この場合、電力線(1)は正規に接続することも可能で
あるが、加工日数が1週間/l接続部を要することから
、撚合せ機械の占有期間が長(なり、生産効率の而で必
ずしも好ましいとはいえない。In this case, it is possible to connect the power line (1) normally, but since the processing time is 1 week per liter of connection, the period of occupation of the twisting machine is long (which means that it is not always possible to reduce production efficiency). I can't say it's desirable.
これに対し、仮接続の場合は10時間/1接続部ですみ
、生産性の面でも実用的である。On the other hand, in the case of temporary connection, only 10 hours/one connection is required, which is practical in terms of productivity.

) is twisted into a long composite cable (22). While unwinding it onto another drum, pull out the area near the temporary connection part, and untwist the power line (Otori) and communication line (2) in this part. , the temporary connections are dismantled for each fiber of the power line (0), and after the regular connection is made, the cables are twisted together with the communication line (2) to their original state, and then wound up on a drum one after another. In this way, a continuous long power line/communication line composite cable can be manufactured.
第4図(イ)〜(ハ)はいずれも本発明における仮接続
部形成の具体例の説明図である。FIGS. 4A to 4C are explanatory diagrams of specific examples of forming temporary connection portions in the present invention.
第4図(イ)は電力線(IA)(IB)の導体同志を銀
ろう又は銅ろう溶接等で等外径に接続(31) L、た
後、スペニサ(32)を被せるか、テープ巻等により電
力線(IA)(IB)と等外径に仕上げる。Figure 4 (a) shows the conductors of the power lines (IA) and (IB) connected to the same outer diameter by silver solder or copper solder welding (31), then covered with a spanner (32) or wrapped with tape, etc. Finish to the same outer diameter as the power lines (IA) and (IB).
この場合、このまま撚合せると通信線は電力線になじみ
易いが、後工程で電力線(IA)(IB)を正規に接続
し、電力線と通信線を撚合せた時に、電力線の接続部の
外径が大きくなる分をカバー出来ない。In this case, if the communication wires are twisted as they are, the communication lines will easily fit into the power lines, but when the power lines (IA) (IB) are properly connected in the later process and the power lines and communication lines are twisted together, the outer diameter of the power line connection will change. It cannot cover the increase in size.
即ち、通信線はその撚合せ層心径が変うた時に対応出来
るだけの余裕がなくピンと張ってしまう。In other words, the communication line does not have enough room to accommodate changes in the twisted layer core diameter and becomes taut.
従って、この対策としては、電力線の接続部近傍、約2

正規の接続終了後に人手で電力線と通信線の撚合せを行
なう時に、撚りピッチを大きくしていきながら外径が大
きくなったところにも通信線をスムースに撚り入れてい
くようにする。Therefore, as a countermeasure, approximately 2
Keep the twisting pitch of about 0m closer than other parts,
When manually twisting power lines and communication lines after completion of regular connection, the communication lines are smoothly twisted even in areas where the outer diameter increases while increasing the twisting pitch.
即ち、撚りピッチを密にして通信線に余尺を作っておく
方法である。That is, this is a method in which the twisting pitch is made dense to create extra length in the communication wire.
又他の方法としては、上述のように撚りピッチを密にす
ることなく、通信線に必要な余尺に相当する長さだけ、
正規の接続時に電力線を切断して除去する方法も考えら
れる。As another method, without making the twisting pitch dense as mentioned above, only the length corresponding to the extra length required for the communication line is used.
Another possible method is to disconnect and remove the power line during normal connection.
第4図(ロ)はあらかじめ電力線の接続部外径が太き(

後、上述の(イ)図の場合と同様にして燃合せを行ない
、電力線の正規の接続時にこのスペーサ(33)を切断
除去して、それぞれの電力線(IA)(IB)を接続す
る方法である。即ち、上記スペーサ(33)の長さが通
信線を外径が大きい接続部に撚り入れていく時の撚り入
れ余尺となる。Figure 4 (b) shows that the outer diameter of the connection part of the power line is thick (
Therefore, calculate in advance the length of the communication line that will be required, and use a conductor spacer (
33) between the planes of the conductors of the power lines (IA) and (1B), and connect them to the same outer diameter with silver solder or copper solder welding (after 30 minutes, do the same as in the case of figure (A) above). In this method, the spacer (33) is cut and removed when the power lines are properly connected, and the power lines (IA) and (IB) are connected.In other words, the length of the spacer (33) is This provides extra length for twisting when twisting communication wires into a connection part with a large outer diameter.
第4図(ハ)は、同図(イ)と同様に導体を接続した後

上に撚合せる方法である。Figure 4 (C) shows that after connecting the conductors in the same way as in Figure 4 (A), a spacer (34) in the shape of a regular connection part is covered.
When twisting the communication wires with the assumption that the outer diameter will be thick (), and when connecting the power lines properly in the later process, remove this spacer (34) and make the connection part with the same shape as this. This is a method of twisting the communication line smoothly onto the power line connection part by finishing it.
以上のような方法により、電力線に外径の太きい接続部
が形成されても、通信線は接続部のない一連長で、品質
上特に問題なくスムースに電力線の接続部上に撚合せる
ことが可能となる。By using the method described above, even if a connection part with a large outer diameter is formed on a power line, the communication line is a continuous length without any connection part, and can be twisted smoothly onto the connection part of the power line without any quality problems. It becomes possible.
