Title:
INDUCTIVE CHARGING PORTS FOR PORTABLE COMPUTING DEVICES
Document Type and Number:
WIPO Patent Application WO/2017/147459
Kind Code:
A3
Abstract:
Connector assemblies may be space efficient, have a high corrosion resistance, are difficult to damage, reduce or prevent moisture leakage into an electronic device housing the connector assembly, are readily assembled, and are reliable. One example may provide an inductive charging port for transferring electrical energy from a first electric device to a second electronic device. As compared to conventional connector inserts and connector receptacles, these inductive charging ports may have a smaller form factor and consume a reduced volume in an electronic device. Corrosion resistance may be provided by including a protective layer or cover portion over what would otherwise be exposed surfaces of a transformer core. Orings, gaskets, or other structures may be included to reduce moisture leakage into a device. The inductive charging port may include a low number of parts for a simplified assembly, and thermal management of various types may be used to improve reliability.
