MOLDED TYPE ISOLATING TRANSFORMER AND METHOD FOR MANUFACTURING THE SAME BY PRODUCING BOBBIN ASSEMBLY THROUGH INSERTION OF ENDS OF WIRES INTO SLEEVE MOUNTING GROOVES FORMED AT BOBBIN CASE AND SECURING BOBBIN INSERTS INTO CENTER OF BOBBIN ASSEMBLY

PURPOSE: A molded type isolating transformer and a manufacturing method thereof are provided to allow for a stable control without causing flickering of lighting device, by supplying secondary power of stable voltage. CONSTITUTION: A method for manufacturing a molded type isolating transformer comprises a step of producing a bobbin assembly by inserting a circular core between a pair of upper and lower bobbin cases(41); a step of winding a primary wire(56) and a secondary wire on the bobbin case of the bobbin assembly; a step of inserting ends(56a,56b,57a,57b) of primary and secondary wires into respective knob(54); a step of inserting bobbin inserts(60,70) into a bottom center surface of the bobbin case; a step of connecting a primary plug wire, a primary receptacle wire, and a secondary receptacle wire to the ends of the primary and secondary wires by using a sleeve; a step of depositing an adhesive to one sides of the bobbin inserts secured to the bobbin assembly; a step of fixing the bobbin inserts to a mounting rod of a lower mold; and a step of injecting resin between an upper mold and the lower mold, and hardening the resin.
