本考案は海底または水中吊下げケーブルとして
用いられる光・電力複合ケーブルに係わる。[Detailed Description of the Invention] The present invention relates to an optical/power composite cable used as a submarine or underwater suspension cable.

特性の低下を招く恐れが生じてくる。 FIG. 1 shows, in cross section, an example of a conventional optical/power composite cable for suspension on the seabed or underwater. In the figure, 1 is an insulated conductor in which a conductor 2 is coated with an insulating coating 3, and 4 is an optical fiber cable. In this example, three insulated conductors 1
and three optical fiber cables 4 are twisted together with an intervening material 5, a holding tape 6 is wound on top of the cable, and the outermost layer is a double layer made by twisting iron wires 7, 7' in opposite directions. A protective gear 8 is provided. As is clear from the drawings, the optical fiber cables are housed in the gaps created when they are twisted together. In such a configuration, when the cable is bent, expansion and contraction occur within one pitch of the optical fiber twist, but the permissible elongation of the optical fiber is as small as about 1%, and the optical fiber cable twists within one pitch. If the cable is not moved, it may stretch beyond the allowable stretch and cause the optical fiber of the optical fiber cable to break. Also, if the cable is wound on a reel while applying tension, the optical fiber cable may be deformed due to lateral pressure, resulting in damage or damage. There is a risk that optical transmission characteristics will deteriorate.

ーブルを提供するものである。 The present invention provides an optical/power composite cable for suspension on the seabed or underwater, which has a new configuration without causing damage to the optical fiber cable or optical fiber as described above.
以下第２図Ａ，Ｂに示す本考案の実施例につい
て説明する。図Ａは横方向の断面図であり、図Ｂ
は長さ方向の一部断面図である。 The embodiment of the present invention shown in FIGS. 2A and 2B will be described below. Figure A is a lateral cross-sectional view, and Figure B
is a partial cross-sectional view in the longitudinal direction.

介在物が添えられ、撚り合わせ体として断面が円
形になるように形成される。 In the figure, reference numeral 11 denotes a sector-shaped conductor, on which an insulating coating 12 of plastic or the like is applied to form an insulated conductor 10. Gather three insulated conductors 10,
The presser/seat layer 13 is formed by wrapping a high-strength tape such as a metal tape on the twisted material. Then, on this presser/seat layer 13, a high-strength stepped tape 14 such as a metal tape is butt-wound to form an optical fiber cable support layer 16 having a spiral recess 15 due to the steps. The optical fiber cable 4 is housed in the recess 15, and a high-strength tape such as a metal tape is wrapped over the optical fiber cable 4 to form a pressing layer 17. For example, the iron wire 7,
7′ double casing 8 with opposite twisting direction;
8' is provided. In this embodiment, a fan-shaped insulated conductor is used to reduce the outer diameter, but a round insulated conductor as shown in FIG. 1 may also be used. In this case, an inclusion is added to the gap formed by each insulated conductor, and the twisted body is formed so as to have a circular cross section.

は全く生じない。 As described in the embodiments above, in the present invention, by adjusting the width of the stepped tape in comparison with the twisting pitch of the insulated conductor 1, the concave portion 15 on the stepped tape wound butt-wound is adjusted.
Since the optical fiber cable 4 can be spirally wound with a much smaller pitch, the stretching of the optical fiber cable due to bending and stretching of the cable is extremely small, eliminating the risk of wire breakage, and the recess for storing the optical fiber cable. 15 is also secured sufficiently, and this recess 15 is protected by the high-strength stepped tape 14, the seat floor layer 13, and the presser tape 17, so that even if tension is applied to the linings 8 and 8', the stepped tape will remain intact. The concave portion 15 due to the step 14 does not form a bridge and the concave portion is not crushed, and the optical fiber cable is not deformed or damaged due to lateral pressure or deterioration of the optical transmission characteristics due to such deformation or damage occurs at all.
