It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In order to solve the above-mentioned technical problems, this embodiment provides a flat data cable, as shown in fig. 1, the first core wire assembly 10, and several groups of the second core wire assemblies 20 and the third core wire assembly 30, and several groups of the second core wire assemblies 20 and the third core wire assemblies 30 are symmetrically disposed on two sides of the first core wire assembly 10 along the horizontal direction, so that the overall structure of the cable is flat, and then the surfaces of the first core wire assembly 10, the second core wire assembly 20 and the third core wire assembly 30 are attached with the hot melt polyester tape 40, and the hot melt polyester tape 40 is heated, so that the hot melt polyester tape 40 is adhered and wrapped on the first core wire assembly 10, the second core wire assembly 20 and the third core wire assembly 30, thereby the hot melt polyester tape 40 plays a role of insulation and fixing structure, and the interval between any adjacent two of the first core wire assembly 10, the second core wire assembly 20 and the third core wire assembly 30 is 0.5-0.6 mm, so that the adhesion of the hot melt polyester tape 40 is tight, and thus the components form a stable whole, and the need not to reduce the damage to the core wire of the cable, and the requirement of the cable is met.

Specifically, as shown in fig. 2, the first core wire assembly 10 includes a plurality of first core wires 11 disposed in parallel, and a first shielding layer 12 and a first self-adhesive polyester tape 13 sequentially coated on the first core wires 11. The first shielding layer 12 is an aluminum foil, wherein two first core wires 11 are taken as examples, the first core wires 11 can be used as signal wires, the two first core wires 11 are placed in parallel, then the longitudinal aluminum foil is used as a shielding, and the longitudinal aluminum foil can be completely attached to the first core wires 11, so that signal leakage is prevented, and external interference is shielded. After the first shielding layers 12 are wrapped on the first core wires 11, the first core wires 11 and the first shielding layers 12 are wrapped and fixed through the first self-adhesive polyester tapes 13, so that the first core wire assembly 10 forms a stable structure.

The first core wire 11 includes a first silver-plated conductor 111 and a first insulating layer 112 covering the first silver-plated conductor 111.
