INDUCTIVE CHARGING INTERFACE WITH MAGNETIC RETENTION FOR ELECTRONIC DEVICES AND ACCESSORIES

摘要

An inductive charging interface with magnetic retention can be used for charging electronic devices and accessories. For example, a magnetic core of an inductive charging configuration may be divided into two magnetic elements, one element can be housed within a receptacle or receiving connector of housing of an electric device and the other element can be housed within a plug or transmission connector. The poles of the two elements of the magnetic core may create a magnetic field to retain the plug connector in an aligned, mated position with the receptacle connector of the electronic device in addition to directing magnetic flux to flow in a circular path around and between the two elements of the magnetic core, thereby inducing a current for charging the internal battery of a device.

主权项

1. A plug connector supporting inductive charging, the plug connector comprising:
a magnetic element having poles aligned to generate a magnetic field that attracts a corresponding receptacle connector of an electronic device and orients and aligns the plug connecter therewith; a wire wound around the magnetic element to form an inductive transmission coil; an electrical connection coupled to the inductive transmission coil and configured to apply a current to the inductive transmission coil to induce a current in an inductive receiving coil of the corresponding receptacle connector; and a magnetically permeable window adjacent to the magnetic element, the magnetically permeable window forming a portion of an exterior surface of the plug connector, the magnetically permeable window configured to allow magnetic flux to flow to and from the corresponding receptacle connector when the corresponding receptacle connector is mated with the plug connector.
