FOCUS PACK OF FLY BACK TRANSFORMER HAVING COUPLING PIN TO BE INSERTED INTO HOLE FORMED AT PRINTED CIRCUIT BOARD, AND FLY BACK TRANSFORMER HAVING THE SAME

摘要

PURPOSE: A focus pack and a fly back transformer are provided to easily and quickly attach the fly back transformer to a printed circuit board by coupling the pin protruded from bottom of the fly back transformer to the hole formed at the printed circuit board. CONSTITUTION: A focus pack(26) comprises a bleeder resistance accommodated in the focus pack; a plurality of knobs for varying focus voltages and screen voltage of a cathode ray tube; a lead wire guide(28) for guiding a lead wire(32) to an open side of a transformer case(12) arranged beneath the focus pack; and a coupling pin(24) protruded downward from the lead wire guide such that the coupling pin is inserted into the hole formed at a printed circuit board where a fly back transformer(10) is to be assembled.
