As the further improved technical scheme of the utility model: the cross section of described cable is oval, includes end face, the bottom surface parallel with end face, connects two arcuate flanks of end face and bottom surface respectively.
As the further improved technical scheme of the utility model: it is the 3rd heart yearn unit, one group of second heart yearn unit, two group of first heart yearn unit, the 3rd heart yearn unit that the Width of described first, second and third heart yearn unit cable along the line is arranged in order from left to right.
As the further improved technical scheme of the utility model: described cable is USB 3.0 cables, and the first heart yearn unit comprises two groups of sub-heart yearns that are used for differential signal transmission.
As the further improved technical scheme of the utility model: described the first heart yearn unit comprise a pair of differential signal line to and with the earth connection of corresponding each differential signal line to cooperating, and differential signal line is enclosed with screen to, earth connection periphery.
As the further improved technical scheme of the utility model: described each differential signal line is sub-heart yearn circular and that arrange side by side to having two cross sections, the upper and lower of two strip heart yearn adjoiners forms the groove that two cable length directions along the line extend, and earth connection places in this groove.
As the further improved technical scheme of the utility model: the Width of the cable along the line of the sub-heart yearn that described each differential signal line is right is arranged.
As the further improved technical scheme of the utility model: described the second heart yearn unit comprise the holding wire that can be used for USB2.0 to and the screen that is wrapped in its periphery, holding wire in the second heart yearn unit is two circular strip heart yearns to having the cross section, and the Width of two strip heart yearns cable along the line is arranged.
As the further improved technical scheme of the utility model: described the 3rd heart yearn unit comprises the two strip heart yearns that can be used for power delivery, and the cross section of two strip heart yearns is circular, and the Width of cable along the line is arranged.
Compared to prior art, the utility model cable becomes flat, and the heart yearn unit in it is that individual layer arranges that the arragement direction of heart yearn unit is consistent with the Width of cable, and overall structure is relatively simple, and wire rod self and assembly cost are all lower.

Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and specific embodiments the utility model is described in detail.
See also shown in Figure 1ly, the cable in the present embodiment can be used for the USB3.0 interface data transmission of standard.Certainly, meeting in the necessarily required situation, this cable also can be used for the transfer of data of other interfaces.
Cable in the utility model is a kind of flat USB 3.0 cables, its cross section (with cable shafts to vertical face) be roughly ellipse, include end face, the bottom surface parallel with end face, connect two arcuate flanks of end face and bottom surface respectively.
But described cable comprises 1, one group of second heart yearn unit 2, the first heart yearn unit and a pair of the 3rd heart yearn unit 3 of two groups of differential signal transmissions.The Width of above-mentioned heart yearn unit cable along the line is arranged, and is aligned in sequence with from left to right: the 3rd heart yearn unit 3, one group of second heart yearn unit 2, two group of first heart yearn unit 1, the 3rd heart yearn unit 3.
