Abstract:
A coil bobbin for an AC adapter comprising:two flanges formed at both ends of a winding drum and coils being wound around the winding drum;an electronic circuit disposed in one of said flanges;a pair of terminal blades disposed in the other flange;a core surrounding the two flanges and the coils; andan attaching portion formed on a lower portion of said one of the flanges,wherein grooves are formed in a first row in the attaching portion so that an edge portion of a substrate is insertable in said grooves, the grooves being means for mounting the substrate with first electronic components configuring said electronic circuit mounted thereon,wherein cavities are formed in a second row below the first row of the attaching portion, the cavities being another means for directly mounting second electronic components by inserting lead terminals of the second electronic components into the cavities,wherein the electronic circuit is a rectifying circuit converting an alternate current to a direct current, andwherein the attaching portion can either directly receive the edge portion of the substrate with the first electronic components mounted thereon into the grooves, or the lead terminals from the second electronic components can be directly inserted into the cavities.
