Abstract

An assembly of cable and connector includes a flat flexible cable, an input-output connector and a paddle card. The flat flexible cable has parallel conductor wires, an insulated layer wrapped around the conductor wires. The conductor wires have at least one first integrated power wire and signal wires. A width of the first integrated power wire is larger than two times the width of one signal wire. The input-output connector has terminals separated into an upper-side terminal and a lower-side terminal. A number of the terminals is larger than a number of the conductor wires. The paddle card has a base board, and transferring circuits distributed on the base board. The transferring circuits has first pads on one side of the base board which are correspondingly connected to the conductor wires, and second pads on the other side of the base board which are correspondingly connected to the terminals.

First claim

What is claimed is:

1. An assembly of cable and connector, comprising:
a flat flexible cable, having a plurality of conductor wires arranged parallel to each other, an insulated layer wrapped around the conductor wires, wherein the conductor wires include at least one first integrated power wire and a plurality of signal wires, a width of each of the at least one first integrated power wire being larger than two times a width of one of the signal wires;
an input-output connector, having a plurality of terminals, the terminals including a plurality of upper-side terminals and a plurality of lower-side terminals, wherein a number of the terminals of the input-output connector is more than a number of the conductor wires of the flat flexible cable; and
a paddle card, having a base board, and a plurality of transferring circuits distributed on the base board, the plurality of transferring circuits including a plurality of first pads distributed on one side of the base board, and a plurality of second pads distributed on another side of the base board, the first pads being connected to the conductor wires of the flat flexible cable correspondingly; the second pads being connected to the terminals of the input-output connector correspondingly; wherein all the first pads of the paddle card have an identical interval therebetween;
wherein an interval is formed between two neighboring signal wires, and a width of the first integrated power wire being equal to two times a width of the signal wire and one of the interval, wherein all wires have the identical interval.

2. The assembly of cable and connector of claim 1 , wherein the conductor wires further include a non-integrated power wire disposed at one side of the first integrated power wire.

3. The assembly of cable and connector of claim 1 , wherein the conductor wires include a second integrated power wire, a width of the second integrated power wire is larger than a width of the first integrated power wire.

4. The assembly of cable and connector of claim 3 , wherein a neighboring two of the signal wires has an interval, wherein a width of the second integrated power wire is equal three times a width of one of the signal wires and two times a width of the interval, and the second integrated power wire is correspondingly soldered to three of the first pads.

5. The assembly of cable and connector of claim 1 , wherein a thickness of the first integrated power wire is larger than a thickness of the signal wire.

6. The assembly of cable and connector of claim 1 , wherein a number of the first pads is equal to a number of the conductor wires, a number of the second pads is equal to a number of the terminals, a number of the conductor wires is smaller than a number of the terminals.

7. The assembly of cable and connector of claim 1 , wherein the first pads include at least one integrated power pad and at least one signal pad, a width of the integrated power pad is larger than a width of the signal pad, the at least one integrated power pad is correspondingly connected to the first integrated power wire.

8. The assembly of cable and connector of claim 1 , wherein the flat flexible cable further includes a shielding layer covered on a periphery of the insulated layer.

9. The assembly of cable and connector of claim 8 , wherein the conductor wires include at least one ground wire, and a transferring conductor, the transferring conductor connects the at least one ground wire to the shielding layer.

10. The assembly of cable and connector of claim 3 , wherein the input-output connector is complied with a USB Type-C specification, and a predetermined number of the terminals which are designated to transmit power connect to the at least one first integrated power wire, thereby the at least one first integrated power wire is able to transmit a current over two times each of the terminals which are designated to transmit power.

11. The assembly of cable and connector of claim 1 , wherein all the first pads of the paddle card have identical width, and the first integrated power wire is correspondingly soldered to two of the first pads.

12. The assembly of cable and connector of claim 1 , wherein a number of the first pads of the paddle card is less than a number of the second pads, and a number of the first pads is equal to a number of the conductor wires; wherein a number of the second pads is equal to a number of the terminals, and a number of the conductor wires is less than a number of the terminals.

13. The assembly of cable and connector of claim 12 , wherein the first pads includes at least one integrated power pad and at least one signal pad, and a width of the integrated power pads is larger than a width of the signal pad, and the integrated power pad is correspondingly connected to the first integrated power wire.
