CONTACTLESS POWER RECEIVING DEVICE AND JIG FOR MANUFACTURE OF CORE FOR THE RECEIVING DEVICE

WIPO Patent Application WO/2010/068063

A2

The present invention relates to a contactless power receiving device and a jig for the manufacture of a core for the receiving device. More specifically, both a power receiving coil of a charging system and a loop antenna of an electronic payment system are mounted in the battery pack and cover case of a portable terminal, with the power receiving coil being positioned at the central portion and the loop antenna being positioned on the outskirts, and a receiving mode of a wireless power signal and a transmitting/receiving mode of data are then executed selectively. As such, impact of interference caused by harmonics is eliminated in advance, and contactless charging as well as electronic payment can be performed through one portable terminal. Particularly, there are provided diverse layouts for the control modules of the contactless charging system using the wireless power transmission/receiving technique and of the electronic payment system using near-field communication, and a jig for the manufacture of a coil with merits of both the circular and rectangular coils. Thus, the reliability for a contactless charging system is improved, which leads to easier manufacturing and sales of portable terminals, battery packs, etc., and an increased competitiveness of such products.
