Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

WHAT IS CLAIMED IS:

1. A wireless power transfer system comprising:

a wireless power transfer device, comprising a first connector portion;

an electrical device comprising a second connector portion; and a wiring harness comprising:

a cable;

a first end connector portion at one end of the cable, the first end connector portion being configured to be removably connected to the first connector portion; and

a second end connector portion at the other end of the cable, configured to be removably connected to the second connector portion.

2. The wireless power transfer system of claim 1, wherein the electrical device comprises a battery charging system.

3. The wireless power transfer system of claim 1, wherein the electrical device comprises a power supply.

4. A wiring harness for a wireless power transfer system, comprising:

a plurality of cables, each comprising a plurality of conductive filaments;

a first connector portion connected to a first end of the cables, the first connector portion comprising a plurality of pins each comprising a recessed end, and

wherein an end of each of the cables is soldered into the respective recessed ends.

5. The wiring harness of claim 4, wherein each cable comprises litz wire.

6. The wiring harness of claim 4 or claim 5, wherein each pin is rated for at least 23A(rms).

7. The wiring harness of any one of claims 4 to 6, wherein each pin is rated for at least 830V(rms).

8. The wiring harness of any one of claims 4 to 7, wherein each pin is made of copper.

9. The wiring harness of any one of claims 4 to 8, wherein each pin comprises a cylindrical contact surface.

10. The wiring harness of claim 9, wherein the cylindrical contact surface is at least substantially 4 mm in diameter.

11. The wiring harness of any one of claims 4 to 10, wherein at least two of the cables have a first designation and at least two of the cables have a second designation, and wherein the first connector portion is configured to receive the pins such that the voltage isolation between the cables of the first designation and the second designation is greater than that between the cables of the same designation.

12. The wiring harness of any one of claims 4 to 11, wherein the first connector portion is configured to have no conductive loops between the pins.

13. The wiring harness of any one of claims 4 to 12, wherein the first connector portion comprises a housing which alleviates bending of the cables at or adjacent the pins.

14. The wiring harness of claim 13, wherein the housing comprises means for fastening the first connector portion in a socket.

15. A method of manufacturing a wiring harness for a wireless power transfer system, comprising:

for a plurality of cables each comprising a plurality of conductive filaments, soldering the respective conductive filaments together to form a plurality of terminated cables;

inserting each terminated cable into a respective recessed end of a pin of a first connector portion; and

applying heat to each terminated cable such that the conductive filaments are soldered to the pins.

16. The method of claim 15, wherein terminating each cable comprises inserting the conductive filaments of the cable simultaneously into a solder pot.

17. The method of claim 16, wherein the temperature of the solder pot is maintained within a range of substantially 350 degrees Celsius to substantially 450 degrees Celsius.

18. The method of claim 17, wherein the temperature of the solder pot is maintained at substantially 450 degrees Celsius.

19. The method of any one of claims 15 to 18, further comprising inserting the pins into a housing which prevents bending of the cables at or adjacent the pins.
