ABL RESISTOR COUPLING STRUCTURE FOR FLY BACK TRANSFORMER

摘要

PURPOSE: An automatic brightness limit(ABL) resistor coupling structure is provided to reduce the size of the fly back transformer by reducing the number of connection terminals of the high voltage bobbin. CONSTITUTION: An ABL resistor coupling structure comprises a low voltage bobbin(2) having a semi-cylindrical fixing portion formed at an end of a terminal of the low voltage bobbin so as to fix an ABL resistor(1); and a high voltage bobbin(3) having an upper portion where a terminal connected to the ABL resistor, a diode connection terminal and a high voltage output terminal(7) are formed, and a lower portion where a high voltage cable insertion hole and a diode connection terminal are formed. The low voltage bobbin is coupled to the high voltage bobbin from the top of the high voltage bobbin. The ABL resistor has a side connected to an ABL resistor(5) of the high voltage bobbin and the other side connected to the terminal of the low voltage bobbin.
