Abstract
The present invention pertains to a transformer, and more specifically, to a transformer which includes a primary coil unit comprising wound conductive lines, and a secondary coil unit in which conductive plates are stacked. The transformer according to an embodiment of the present invention may include: a bobbin; a core unit which is coupled to the bobbin along the outer side of the bobbin; and a plurality of conductive plates which are inserted into the bobbin and stacked in the thickness direction.
Claims19
A transformer, comprising:
- a bobbin;
- a core part disposed outside the bobbin to expose a portion of the bobbin;
- and
- a plurality of conductive plates inserted into the bobbin, the plurality of conductive plates being stacked in a thickness direction,
- wherein the bobbin has therein openings to respectively expose, among the plurality of conductive plates, a portion of an upper surface of a conductive plate located at an uppermost position in the thickness direction and a portion of a lower surface of a conductive plate located at a lowermost position in the thickness direction.
