Abstract

Disclosed herein is an apparatus for wirelessly transmitting power. The apparatus for wirelessly transmitting power includes a transmission coil configured to change a magnetic field in response to an AC current, a shielding unit configured to restrict the propagation of the magnetic field generated from the transmission coil, and a casing configured to surround the transmission coil and the shielding unit. The transmission coil is formed in a single layer form by winding a wire along the sides of an isosceles triangle having a height greater than a base in the same plane, and the transmission coil may have a perimeter height of 52+ / -0.5 mm, an inside height of 34+ / -0.5 mm, a perimeter width of 46+ / -0.5 mm, an inside width of 28+ / -0.5 mm, and a thickness of 1.1+ / -0.3 mm. The transmission coil may be formed by winding the wire on the sides of the isosceles triangle eight times.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of prior application data and priority claims from Korean Patent Application No. 10-2014-0067950 filed on June 3, 2014, the contents of which are incorporated herein by reference in their entirety. technical field [0003] The invention relates to devices for the wireless transmission of electrical energy. Background technique [0004] With the development of current communication and information processing technologies, the use of smart terminals such as smart phones is gradually increasing. A method commonly used for charging smart terminals is to directly connect an adapter connected to a power source to the smart terminal and use an external power supply to charge the smart terminal, or a method of connecting the adapter to the smart terminal through a USB terminal of the host and using The method of charging the smart terminal with the USB power supply of the host.
