Technical Field

In this embodiment, the middle gap 12 and/or the edge gap 13 are filled with an insulator 15, the insulator 15 is a glue and/or a solid insulator, the filled insulator 15 can stabilize the displacement between the plurality of flat conductor wires 11 or enhance the insulation reliability, and is beneficial to the bonding stability between the flat conductor wires and the upper and lower insulating layers 3, and also can enhance the tensile strength and the bending strength of the whole body, and is convenient for forming a colored identification strip to distinguish the line sequence or the starting end of the line sequence of the whole body on the left and right sides and/or each flat conductor wire 11. In addition, the proper filling thickness can also enable the whole body to have a smoother visual effect.

In this embodiment, the insulating layer 3 is formed by compounding one insulating film or a plurality of insulating films. The insulating layer 3 is provided with a decorative layer 4 to achieve a decorative effect similar to or in sharp contrast to that of using a background color.

The decorative layer 4 is a decorative coating printed on the insulating film of the insulating layer 3 and/or a decorative film attached to the outer surface of the insulating layer 3. In this embodiment, the decorative layer 4 is formed by attaching a decorative film to the outer surface of the insulating layer 3.

In addition, in order to solve the problem of the initial sequence of the flat conductor wires 11 laid side by side in the transverse direction in the present embodiment, the colored identification strips 5 which are longitudinally distributed and distinguish the left and right directions may be provided in the flat conductor wires 11, the middle gap 12, the edge gap 13, the insulator 15, the glue layer 2, the insulating layer 3 and/or the decorative layer 4.
