Abstract:
An electronic device may include a noise shielding device that may include: a substrate including at least one heat generating component; a metallic shield cover that is disposed on the substrate to enclose the at least one heat generating component; a metal housing disposed around the shield cover; and a heat transfer member that is configured to transfer heat emitted from the heat generating component through an opening formed at a position corresponding to the heat generating component to the metal housing, wherein the metallic shield cover includes a plurality of tension fingers that protrude at predetermined intervals and contact a bottom face of the metal housing, and noise emitted from the heat generating component is shielded by a shielding region that is formed by the tension fingers and the metal housing.
Abstract:
A battery charging control system of a terminal is provided. The system includes a terminal in which a battery is mounted and a charger connected to the terminal to provide a charging current for charging the battery. The charger charges the battery with a maximum margin current value that is greater than a rated current value of the charger.
