COMPOSITE MAGNETIC CORE AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to a composite magnetic core and a method for manufacturing the same. To this end, the present invention comprises: a hardened lower core (20) having a groove (21); a hardened inner core (30) seated to protrude from the top of the groove (21); a pair of insulation wires (40) which are located at the upper ends of the groove (21) and equidistantly arrange the inner core (30) on upper/lower/left/right sides; an upper core (10) which is seated on the upper ends of the lower core (20) and the inner core (30) and is placed on in a gel state and is then high-temperature-treated so as to be integrally formed with the lower core (20); and a conducting wire (50) wound on the outer peripheral surfaces of the upper/lower cores (10) and (20) to enable current to flow. The present invention as configured above enables the production and manufacture of different types of dual or more composite magnetic cores in large quantities, thereby greatly improving the quality and reliability of a product and thus satisfying various needs of consumers, which are users, to provide a good image.
