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 the transformer that flies back are provided to by connected nail and easily and quickly add the transformer that flies back to a printed circuit board, are protruded from the bottom for the transformer that flies back to the hole for being formed in printed circuit board. Construction: a focus pack (26) includes a bleeder resistance for being contained in focus pack; Multiple knobs are used for the different focus voltages and screen voltage of a cathode-ray tube; One lead guide (28), for instructing a lead (32) that a wide side of a transformer case (12) to be arranged under focus pack; One coupling pin (24) is downwardly projected from lead guide, and such coupling pin is inserted into the hole for being formed in a printed circuit board, wherein the transformer (10) that flies back will be assembled.
