In such cases, it is possible to easily connect the tension wires constituting one optical fiber cable to the tension wires in other optical fiber cables or the other tension wires with a small outer diameter and mechanically strong connection. It depends on the connection method to achieve this.

形に撚り合わせた複合架空地線である。 Optical fiber cables can transmit large amounts of information, and because they are low loss, non-inductive, and insulating, optical fibers are incorporated into overhead ground wires to transmit information between substations. It is considered to be used for purposes such as transmission of information, transmission of information on power transmission lines, and countermeasures against television interference, and is now entering the stage of practical use. A typical structure of such an optical fiber composite overhead ground wire is as shown in FIG. 1A or 1B. That is, in the case shown in Fig. 1A, an aluminum pipe 2 with a built-in optical fiber cable 1 is arranged at the center, and around it is an aluminum steel-covered wire (circular strand) 3 with a circular cross section and a diameter of this circular strand. This is a composite overhead ground wire in which aluminum wires (segment wires) 4 having a similar size and thickness and a similar rectangular cross section are combined and twisted into a circular shape so as to interlock with each other.

引き入れられるようにしてある。 Such an optical fiber cable 1 is used by being drawn into an aluminum pipe 2 with a certain margin, and its structure is as shown in FIG.
An optical fiber cable 1 is formed by forming a circle around one tension member (tension line) 5a and surrounding it with an optical fiber 6 and another tension line 5b, and applying, for example, a silicone resin sheath 7 on the outside. It is pulled into the aluminum pipe by the action of tension wires.

いことが要求される。 In the actual overhead ground wire, when pulling the optical fiber into the aluminum pipe in advance and when pulling it out, the tension wire as a pull wire prepared separately and the tension wire in the optical fiber cable are connected, and the optical fiber cable is For the purpose of replacement, it is possible to connect the tension wires in the existing optical fiber cable inside the aluminum pipe and the tension wires in the new replacement optical fiber cable, or to connect the existing part of the span of the steel tower where the overhead ground wire will be installed. Therefore, when extending the optical fiber cable, it is necessary to connect the tension wires in the existing optical fiber cable to the tension wires used as traction wires, but if the outer diameter of the connection between the tension wires is larger than the optical fiber cable of the main body. It is required that the connecting portion be smooth and smooth, and that the tensile strength of the connecting portion be not lower than that of other portions.

付けをしたところ、外径は勿論光フアイバケーブ
ルより遥かに小さく、その接続強度も張力線自体
の引張強度に対し95〜98％とほとんど変りがない
というすぐれた成果を収めることができた。 For this reason, the sleeve connection cannot be used because the outer diameter becomes too large. Therefore, it is necessary to connect the tension wires to each other, but since the tension wires are high tensile strength wires such as piano wire, they are not suitable for twist connections. Therefore, in the present invention, when the tension wires to be connected are overlapped to a certain length, copper wire is wound horizontally around the wires, and then soldered, the outer diameter is of course much smaller than that of an optical fiber cable, and the connection strength is also equal to that of the tension wires themselves. We were able to achieve excellent results, with almost no change in the tensile strength of 95% to 98%.
なおこのような、張力線相互の重ね合せる長さ

業能率もよく、有利である。 Note that the overlapping length (connection length) of the tension lines must be the minimum required length since the frictional force increases when passing through the curved portion of the pipe.
Also, it is better to finish the soldered surface neatly with a file. Furthermore, if the soldered surface is coated with low-friction plastic such as nylon or tetrafluoroethylene resin, the friction will be lower than when the solder is exposed. When covering with an ethylene resin tube, the work efficiency is good and it is advantageous.

る。 FIG. 3 is a partially longitudinal front view showing a case where the tension line 5a at the center of the optical fiber cable 1 is connected to the tension line 8 for a traction wire of the same size. A chisel was made to protrude outward for a certain length, and a tension wire 8 of the same material and size was superimposed, bound with copper wire 9, subjected to solder treatment 10, and its surface polished and smoothed, and then inserted in advance. The tetrafluoroethylene resin shrink sleeve 11 is pulled back onto this and tightly attached to connect. By doing this, the outer diameter of the connecting part is not larger than the optical fiber cable, the strength of the connecting part is the same as the strength of the tension line itself, and there is little friction, so the optical fiber cable can be easily drawn into the conduit. , can be removed.

ある。 The tension wires 5a, 5a of both cables 1, 1 are made to protrude from the respective cable ends of the same length, and are overlapped with each other, bound with copper wires 9, subjected to solder treatment 10, and their surfaces polished and smoothed. Then, a tetrafluoroethylene resin shrink sleeve 11 is heat-shrinked onto this to tightly cover it. By doing this, the outer diameter of the connecting part is not larger than that of the optical fiber cable, and the strength of the connecting part is the same as the strength of the tension line itself of each optical fiber cable, and there is less friction, so it can be easily placed inside the conduit. By pulling one optical fiber cable, the other optical fiber cable can be drawn into the conduit, that is, the optical fiber cable in the conduit can be easily replaced.
なお、本発明では張力線を半田接続しているの
に対し比較例として銀ロー付けによつて行なつた
ところ、銀ロー付けの温度は高温であるところか
ら接続部分の張力線が“なまる”ため本体の張力
線の引張強度に比べて40〜50％に引張強度が低下
し実用に耐えないことが判つた。 In addition, in the present invention, the tension wires are connected by soldering, but as a comparative example, the tension wires were connected by silver brazing, and since the temperature of silver brazing is high, the tension wires at the connected portions were "dulled". ``As a result, the tensile strength was reduced to 40 to 50% compared to the tensile strength of the main body tension wire, and it was found that it could not be put into practical use.
本発明は上述のように比較的簡単な方法で接続
部分の外径が小さく、強度が大きく、摩擦の少な
い接続部を提供することができる。 As described above, the present invention can provide a connection portion with a small outer diameter, high strength, and low friction using a relatively simple method.
