Charging mechanism with ground contact and non-contact coupling

摘要

The embodiments provide a device including an enclosure having circuitry associated with the device and a battery configured to power the circuitry, and a power plug receiving unit configured to receive a power plug of a power charger to charge the battery. The power plug receiving unit includes a ground contact that is exposed through the enclosure for contact with a secondary ground contact of the power plug, and an active electrode configured to receive alternating current (AC) energy from the power charger for charging the battery or powering the circuitry via non-contact coupling.

1. A device comprising:
an enclosure having circuitry associated with the device and a battery configured to power the circuitry; and a power plug receiving unit configured to receive a power plug of a power charger to charge the battery, the power plug receiving unit including a ground contact that is exposed through the enclosure for contact with a secondary ground contact of the power plug such that the ground contract and the secondary ground contact, when coupled, create a ground return, an active electrode configured to receive alternating current (AC) energy from the power charger for charging the battery or powering the circuitry via non-contact coupling, and a dielectric material disposed between the active electrode and the ground contact such that the ground contact is electrically isolated from the active electrode.
