This cable l is made by twisting together three insulated power wire cores 2.2.2, two insulated control wire cores 3.3, and one insulated grounding wire core 4. A wire core 5 is formed, a tape made of polyester film is wrapped around the twisted wire core 5 to form a tape wrapping layer 6, and a sheath 7 made of crosslinked polyethylene is extruded and coated on top of this. be.

When an external force such as bending or twisting is applied to the insulated wire core 2.3.4

じる問題を招く。For this reason, it is possible to consider a solid type cable in which the sheath 7 is fully extruded and coated directly on the twisted wire core 5'' without wrapping the tape so as to eliminate the space A in the moving cable 1. If the sheath 7 is completely extruded and coated directly onto the stranded wire core 5 without the winding layer 6, a part of the stranded wire core 5 will be twisted due to the resin pressure (for example, about 50 kg/cm'') during extrusion coating. A birdcage phenomenon occurs in which the product is returned and inflated, resulting in a problem of product defects.

た。"Means for Solving the Problems" In this invention, a tape made of a synthetic resin that melts at the temperature during extrusion coating of the sheath is wound around the twisted wire cores, or when each insulated wire core is twisted together. The solution was to fill the gaps between the strands with adhesive resin and twist the strands together to obtain a stranded core, and then fully extrude the sheath to cover it.

る。``Example'' In the invention according to claims 1 and 2, as shown in FIG. A synthetic resin tape that melts due to the heat during coating is wound to form a molten tape wrapping layer 8. Here, as the synthetic resin forming the tape, polyethylene, irradiation-crosslinked polyethylene, polypropylene, polyvinyl chloride, ethylene-vinyl acetate copolymer, etc. can be used. If, for example, crosslinked polyethylene with an extrusion temperature of about 200 to 230°C is used as the sheath, a thermoplastic synthetic resin with a melting temperature of about 200°C or less is used as the synthetic resin forming the tape. Further, the thickness of the tape is approximately 20 to 150 μm. If the tape thickness exceeds 150 μm, deformation of the sheath during extrusion coating will be insufficient, which is disadvantageous.

い。Furthermore, the above-mentioned tape can also be an adhesive tape provided with an adhesive layer on its lower side. In this case, the adhesive layer used is one coated with an acrylic adhesive, a rubber adhesive, or the like to a thickness of about 5 to 20 μm. When such an adhesive tape is used, the adhesive layer is naturally twisted and attached to the wire core 5.
Wind it tightly. Note that the tape may be wound in a normal lap manner, but the overlapping width should be relatively small, such as 1/6 wrap, so that the substantial thickness of the molten tape wrapping layer 8 does not increase, and the sheath It is desirable that deformation due to pressure during extrusion coating is not inhibited.

ス７が充実状態に被覆形成される。The stranded wire core 5 provided with the fused tape winding layer 8 is then extruded and covered with a sheath 7 in a solid shape by an extruder having a rad die into a normal cloth. During the full extrusion coating of the sheath 7, as shown in FIG. 2, the molten tape-wrapped layer 8 is melted and softened by the heat of the molten resin that will become the sheath 7, and the tape-wrapped layer 8 is further melted and softened by the pressure of the molten resin. is pushed into the twisting gap of each insulated wire core. In this way, the sheath 7 is completely coated around the outer periphery of the twisted wire core 5 with the tape wrapping layer 8 interposed therebetween.

The insulated wire cores 2.3.4 are not twisted and twisted by the pressure of the molten resin and a birdcage phenomenon does not occur. Furthermore, with adhesive tape, even if the adhesive tape is cut during extrusion coating of the sheath 7, it will not peel off from the twisted wire core 5, and the tape will not clog the nipple of the die of the extruder. No obstacles will occur.

つ撚り合せる方法などがある。In the invention described in claims 3 and 4, when the insulated wire cores 2.3.4 are twisted together to form the twisted wire core 5, the molten adhesive resin is applied to the gap between the twists (twisted wire core 5). As shown in FIG. 3, the twisted wire core 5 is filled with the adhesive resin 9. The adhesive resin 9 used here is one with excellent flexibility and adhesive properties, and as a specific example, a melting temperature of 100 to 18
A hot-melt adhesive or the like containing 0° C. modified polyolefin as a main component can be used. Note that this adhesive resin 9 may be made of semiconductive material mixed with carbon or the like, if necessary. Further, as a specific method for filling the adhesive resin 9, there is a method of continuously injecting the molten adhesive resin 9 into the twisting opening portion of a wire twisting machine using an applicator while twisting the wires.

着層を形成した粘着テープなどを用いることができる。The stranded wire core 5 filled with the adhesive resin 9 and twisted together is then covered with a sheath 7 by extrusion in a solid manner by a conventional method, and if necessary, the stranded wire core 5 is further extruded and covered with a sheath. The sheath 7 can also be completely extruded and covered after being wrapped with a synthetic resin tape that melts with the heat of time. The tape used here has a thickness of 60 μm, for example.
Polyethylene tape with a thickness of approximately 25 μm, polypropylene tape with a thickness of approximately 25 μm, and adhesive tape obtained by forming an adhesive layer with a thickness of approximately 10 μm on these tapes can be used.

ない。Even in a mobile cable with such a structure, since each insulated wire core 2, 3, 4 is bonded and integrated with the adhesive resin 9, the birdcage phenomenon when the sheath 7 is extruded and covered is prevented. In addition, since the gaps between the twisted wire cores 5 are filled with adhesive resin 9, the cable does not swell.
