ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an improvement in structure of a wire-wound component such as a transformer, a line filter, and a coil element which is to be mounted on a printed circuit board.
2. Discussion of the Related Art
A conventional wire-wound component is of resin, and metal terminals are fixedly press-fitted in the periphery of the body of the wire-wound component (hereinafter referred to as “component body”, when applicable), and a metal wire is wound around the component body and its two end portions are wound around the metal terminals, to form the aimed wirewound component. In mounting the wire-wound component on a printed circuit board, the metal terminals are inserted into the printed circuit board and soldered to the circuit; or the wire-wound component has a mounting section which is secured to the printed circuit board, and the metal terminals of the wire-wound component are connected through lead wires to the circuit on the printed circuit board.
However, the above-described structure of the wire-wound component to be mounted on the printed circuit board suffers from the following difficulties:
It is necessary to provide special metal terminals which are used for the printed circuit board only, and to press-fit them in the component body, which increases the number of manufacturing steps and the manufacturing cost as much.
In the case where the metal terminals of the wire-wound component are connected through the lead wires to the circuit pattern on the printed circuit board, the number of connecting points is increased as much, which results in an increase in manufacturing cost.
SUMMARY OF THE INVENTION
In view of the foregoing, an object of the invention is to provide a wire-wound component to be mounted on a printed circuit board, the structure of which contributes to a reduction in the number of manufacturing steps and to a decrease in manufacturing cost.
In order to achieve the above object, the invention provides a wire-wound component to be mounted on a printed circuit board, comprising: a wire-wound component body on which a wire is wound; and a molded terminal on which an end portion of the wire is wound, the molded terminal and the wire-wound component body being formed as one unit by molding a heat-resistant resin material.
