Description

BASE AND TRANSFORMER DEVICE INCLUDING THE SAME

The present disclosure relates to base and transformer components.

Electronic devices such as display devices and adapters are provided with a power supply for converting alternating current to direct current. A power supply device is basically equipped with a transformer component (or a transformer) for converting alternating current into direct current, and a conventional transformer component generally has a structure in which a coil is wound around a bobbin, and a core is coupled to the bobbin.

Therefore, since the conventional transformer component basically has a wire-type coil wound around the bobbin, there is a limit to reducing the size of the bobbin. Due to this, there is also a limit to reducing the overall size of the transformer component. In addition, when a transformer component is manufactured in a small size, there is a problem in that it is difficult to secure insulation between the primary and the secondary.
