Abstract:
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.
