Abstract

The present invention provides a coil assembly and a power supply device including the coil assembly. The coil assembly includes: a first coil part including a multilayer substrate on which a conductive pattern is formed; a second coil part composed of a wire Formed and stacked with the first coil part; the core, bonded to the first coil part and the second coil part while penetrating the first coil part and the second coil part, thereby being electromagnetically bonded to the first coil part and the second coil part a coil part; a pressing member disposed between the core and the second coil part so that the first coil part and the second coil part are closely attached to each other.

Description

[0001] This application claims Korean Patent Application No. 10-2014-0120463 filed with the Korean Intellectual Property Office on September 11, 2014 and Korean Patent Application No. 10-2014-0136632 filed with the Korean Intellectual Property Office on October 10, 2014 Priority and Benefit of Patent Application, the disclosures of these two Korean patent applications are hereby incorporated by reference. technical field [0002] The present disclosure relates to a coil assembly and a power supply device including the coil assembly. Background technique [0003] Generally, a coil assembly includes a core, a bobbin, a winding, and the like. [0004] With the miniaturization of coil components, various efforts have been made to ensure sufficient insulation between a winding and a core or between a primary coil and a secondary coil. [0005] In addition, in the case where the winding coil is formed of a wire, there may be a problem in that the coil turns or the winding positio...
