Abstract

A flat cable includes a number of pairs of differential signal wires and a number of power wires distributed on two sides of the differential signal wires. The differential wires are horizontally and vertically arranged in a matrix.

First claim

What is claimed is:

1 . A flat cable comprises:
a plurality of pairs of differential signal wires; a plurality of power wires distributed on two sides of the differential signal wires; and the differential signal wires horizontally and vertically arranged in a matrix.

2 . The flat cable as claimed in claim 1 , further comprising two ground wires distributed on a side of the power wires in a horizontal direction.

3 . The flat cable as claimed in claim 2 , further comprising two detect wires.

4 . The flat cable as claimed in claim 3 , wherein the detect wire is disposed between the power wire and the differential signal wires.

5 . The flat cable as claimed in claim 1 , wherein the power wires are symmetrically distributed along a center line in a vertical direction.

6 . The flat cable as claimed in claim 1 , wherein the differential signal wires comprise a first wire group for transmitting a display signal and a second wire group for transmitting a USB signal.

7 . The flat cable as claimed in claim 6 , wherein the first wire group comprises a first wire for transmitting a first display signal and a second wire for transmitting a second display signal.

8 . The flat cable as claimed in claim 6 , wherein the second wire group comprises a third wire for transmitting a USB 2.0 signal and a forth wire for transmitting a USB 3.0 signal.

9 . A flat cable assembly comprising:
plural pairs of differential pair wires and power wires and ground wires side by side arranged with one another in a transverse direction and enclosed within an insulative jacket; said power wires being symmetrically located by two sides of said plural pairs of differential pair wires; said ground wires being symmetrically located by two sides of said power wires and said plural pairs of differential pair wires; wherein each pair of said differential pair wires are internally side by side intimately arranged with each other in the transverse direction, and all said differential pair wires are symmetrically arranged in two levels for respectively soldering to two opposite surfaces of an internal printed circuit board in an electrical connector.

10 . The flat cable assembly as claimed in claim 9 , wherein there are four pairs of the differential pair wires for a same protocol signal transmission, and two pairs of said four pairs are intimately arranged side by side in said transverse direction while the remaining two pairs of said four pairs are intimately stacked with each other in the vertical direction at two levels.

11 . The flat cable assembly as claimed in claim 10 , wherein the two pairs side by side arranged with each other, are located at a same level with one of said two levels.

12 . The flat cable assembly as claimed in claim 10 , wherein the two pairs side by side arranged with each other, are spaced from the remaining two pairs with a distance in the transverse direction.

13 . The flat cable assembly as claimed in claim 12 , wherein said distance is not less than a transverse dimension of each pair of said differential pair wires.

14 . The flat cable assembly as claimed in claim 9 , wherein there are three pairs of the differential pair wires for another protocol signal transmission, and one pair of said three pairs and two pairs of said three pairs are separated from each other by the remaining two pairs of said four pairs in said transverse direction.

15 . The flat cable assembly as claimed in claim 9 , wherein the ground wires are respectively soldered upon said two opposite surfaces of the printed circuit board.

16 . The flat cable assembly as claimed in claim 15 wherein said power wires are respectively soldered upon said two opposite surfaces of the printed circuit board.

17 . The flat cable assembly as claimed in claim 9 , further including detect wires located between the differential pair wires and the corresponding power wire in the transverse direction.

18 . A flat cable assembly comprising:
plural pairs of differential pair wires and power wires and ground wires side by side arranged with one another in a transverse direction and enclosed within an insulative jacket; each pair of said differential pair wires are internally side by side intimately arranged with each other in the transverse direction, and all said differential pair wires are symmetrically arranged in two levels for respectively soldering to two opposite surfaces of an internal printed circuit board in an electrical connector; wherein there are four pairs of the differential pair wires for a same protocol signal transmission, and two pairs of said four pairs are intimately arranged side by side in said transverse direction while the remaining two pairs of said four pairs are intimately stacked with each other in the vertical direction at two levels.

19 . The flat cable assembly as claimed in claim 9 , wherein there are at least two pairs of the differential pair wires for another protocol signal transmission, and one pair of said at least two pairs and another pair of said at lest two pairs are separated from each other by the remaining two pairs of said four pairs in said transverse direction.
