Embodiment 1

[0051] Example 1 is figure 1 In the cable 11, six twisted wire conductors 13 formed by twisting a plurality of bare conductor wires (soft copper wires (TPC, tough copper)) are arranged around the center. The insulating layer 15 uses cross-linked polyethylene. The shielding layer 16 is braided with tinned copper. The reinforced braided layer 17 uses polyvinyl alcohol fiber material. In addition, the reinforced braided layer 17 may also use a polyethylene terephthalate fiber material or a polyethylene 2,6-naphthalate fiber material. The filler 14 uses a silicon tube made of a silicone resin with a Shore (A) hardness of 45±5 degrees. The dimensions of each component are as image 3 Shown. In addition, the conductor layer is a layer composed of the twisted wire conductor 13.

Embodiment 2

[0052] Example 2 is figure 2 In the cable 21, a plurality of bare conductor wires (same as above) are twisted as a twisted wire conductor 22, and six twisted strands 23 formed by twisting a plurality of twisted wire conductors 22 are arranged around the center. In addition, staple fiber yarn is used for the filler 24. The other layers are the same as in Example 1.

[0053] The cable of the comparative example is Figure 4 As shown, it does not contain fillers and has a figure 1 The filler 14 of the cable 11 becomes a structure of a twisted wire conductor. That is, the cable 41 of the comparative example is twisted with 7 twisted wire conductors 42 formed by twisting a plurality of bare conductor wires (tin-copper alloy) with each other around it figure 1 The cable 11 is similarly provided with an insulating layer 45, a shielding layer 46, a reinforced braided layer 47 and a sheath 48 in order.

[0054] The three cables of Example 1, Example 2 and Comparative Example 3 were subjec...

Abstract

A cable having a cable structure comprising a stranded wire formed by stranding a plurality of stranded conductors and an inclusion that is more deformable than the stranded conductors, wherein a plurality of stranded conductors are arranged on a circumference of the inclusion.

Description

Technical field [0001] The present invention relates to a cable used in an environment where robots or automobiles are subjected to repeated bending. Background technique [0002] Cables used in environments that are subjected to repeated bending, such as robots and automobiles (for example, under the springs of automobiles), require not only high bending durability but also high flexibility from the viewpoint of ease of wiring, for example. However, it has not been possible to achieve both high bending durability and high flexibility. [0003] Patent Document 1 describes the following technology: By providing a tension element having a tensile strength 5 times or more than that of the twisted wire conductor in the overhead distribution line, even if the twisted wire conductor is broken, the overhead distribution line can be prevented from being damaged. Sagging. [0004] Patent Document 1: Japanese Patent Application Publication No. 2002-124137 Summary of the invention [0005] Ho...
