Title: INDUCTIVE CHARGING INTERFACE WITH MAGNETIC RETENTION FOR ELECTRONIC DEVICES AND ACCESSORIES
Abstract:
An inductive charging interface with magnetic retention can be used for charging an electronic device (200). A magnetic core of an inductive charging configuration is divided into two magnetic elements (230, 232), one element (232) can be housed within a receptacle or receiving connector (212) of housing of an electric device (200) and the other element (230) can be housed within a plug or transmission connector (202). The poles of the two elements of the magnetic core create a magnetic field to retain the plug connector (202) in an aligned, mated position with the receptacle connector (212) of the electronic device (200) 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 (238) of the device (200).
