Abstract:
In combination with a wire-wound component mounted on a printed circuit board having a circuit pattern thereon, with non-press fitted connecting terminals, comprising:a wire-wound component body on which one or more conductive wires having an insulative coating is wound;a plurality of molded terminals formed on said wire wound component, and on which an end portion of a conductive wire is wound, said molded terminals and said wire-wound component body being formed as an integral unit by molding same together from a heat-resistant resin material;each of said molded terminals having a base portion having a diameter L1;a first removal preventing portion having a diameter L2 which is smaller than the diameter L1 and extending from said base portion;a winding portion having a diameter L3 which is smaller than the diameter L2 and extending from said first removal preventing portion; anda second removal preventing portion as an end portion having a diameter L4 which is larger than the diameter L3 and smaller than the diameter L1 and extending from said winding portion;wherein due to the diameter L1 of said base portion being larger than a diameter M mating molded-terminal inserting holes formed in said printed circuit board, and the diameters L2 and L4 of said first and second removal preventing portions being smaller than the diameter M, positioning all such molded terminals in said inserting holes is generally easy by virtue of said end portions of said second removal preventing portions serving a positioning function as well; andwherein said plurality of molded terminals are capable of withstanding conversion of the moldeded terminals and said conductive wire into pseudo metal terminals by dipping of same into molten solder, whereby soldering is achieved quickly and positively so that;the number of manufacturing steps and the manufacturing cost for said combination wire-wound component and printed circuit board is substantially reduced as compared to more conventionally manufactured wire wound components mounted on a printed circuit board.
