  In order to increase the data transmission rate and to prevent external interference signals, it is usually necessary to provide a shielding layer for interference signal removal in the cable, and FIG. 1 shows a kind of current widespread cable. A core wire set 51 consisting of a plurality of core wires, a shielding layer 52 for covering the core wire set 51, and an outermost insulation coating layer 53, and a core wire of the core wire set 51 uses a copper core winding; The quantity is provided in accordance with the standard and type of cable, and the shielding layer 52 is usually provided on a woven copper mesh, and is provided so as to cover the entire core wire set 51 by the shielding layer 52, and the outermost In the case of such cables, the copper mesh used as the shielding layer 52 is usually braided with tin-plated copper wire, and the demand for data transmission is increased. Accompanied by such a conventional cable However, it becomes impossible to meet that demand, and has the following drawbacks.

1. The shielding layer made of copper mesh woven with tin-plated copper wire should be complicated to make.
2. In the case of a copper mesh shielding layer, the flexibility of the entire cable is insufficient, and at the same time, the diameter of the cable is large.
3. In the case of using a copper mesh shielding layer, when using a cable, the copper mesh is easily loosened by bending or pulling repeatedly, or the tin plating copper wire for knitting is broken or the shielding effect is weakened. about.

  On the other hand, with the technological development of graphene, it is applied to the fields of materials science, electricity, optics, etc. For example, graphene has mechanical properties such as excellent high strength and toughness, and, theoretically, Young's modulus is 1.0 TPa has an intrinsic tensile strength of 130 GPa, and has an electronic effect superior to common metallic materials.

The conduction band 30 of graphene is spiraled to the core wire set 1 using a winding machine So as to form an overlapping area between the conductive bands 30 of adjacent graphenes that are provided and wound so as to cause the entire core set 1 to be completely covered. By securing the conductive band 30 of graphene, at the same time as having a shielding effect on the core set 1, the core set 1 is wound and fixed.

  The covering layer 2 is provided to cover the shielding layer 3 with a material such as PVC, nylon, rubber or the like to protect and fix the entire cable. And the cross section of the whole cable may be round or flat round, and the present invention is not limited thereto.

  The present invention is applied to various types of cables, such as HDMI (registered trademark) cables, USB cables, and TYPE-C cables.

  Taking the HDMI (registered trademark) cable as an example, the following results can be obtained by comparing the conventional cable shown in FIG.

1. The present embodiment 1 is significantly superior in performance against EMI (battery wave damage) and high frequency signal transmission than the conventional cable.
