PURPOSE: A focus pack of fly back transformer is provided to remove the necessity of filling and curing the insulation resin for a ceramic substrate and simplify the assemble process, thereby enhancing workability and productivity. CONSTITUTION: A focus pack of fly back transformer comprises a focus cover(130), a ceramic substrate(110), focus and screen knobs(170a,170b), cable connectors(220,220') and a focus outer cover(240). The focus cover has a substrate inserting groove(120) and knob fixing grooves(140,140') which a bottom ends of the knobs are fixed to. Knob through holes(150,150') are formed on both sides of the ceramic substrate on which circuit patterns(160) for drawing focus and screen voltage are formed on. The focus and screen knobs have a terminal coupling groove for coupling an output terminal contacted to the circuit patterns via a support bar(190). The cable connector is inserted into the circuit patterns. The outer case is coupled to the focus cover.
