Abstract
A magnetic coupling device is disclosed. The magnetic coupling device includes a core portion including an upper core and a lower core spaced apart from each other in a first direction, a primary coil and a secondary coil disposed between the upper core and the lower core in the state of being spaced apart from each other in the first direction, and a core connector electrically connected to the upper core and the lower core. A discharge phenomenon of a slim magnetic coupling device is prevented by the provision of the core connector.
