  • Patent number: 6856229
    Abstract: The present invention provides an electronic chip component (e.g., a chip inductor) small in size, and a manufacturing method thereof capable of shaping of the outer dimensions of the component into a desirable shape. The method involves press-fitting a chip inductor element into a component storage section of a mold plate comprised of a heat resistant rubber elastic member including the component storage section, while a resin coating material is coated on the element and dried to a dry-to-touch state, thereby hardening the resin coating material and automatically shaping the chip inductor element into a desired outer shape.

  • Patent number: 6727792
    Abstract: A wire wound electronic component of the present invention includes a bobbin having a core 1a having a substantially circular cross-section and rectangular flanges 1b formed at both ends of the core. A groove 2 is formed in each side of each flange 1b. A conductive film or external electrode 3 is formed on each flange 1b. A coil or wire 4 is wound round the core 1a and has a conductor protruding from opposite stripped ends thereof. The opposite ends 5 of the conductor are respectively received in the grooves 2 of the flanges 1b and connected to the conductive films 3. A coating or armor 6 is formed on the coil 4 and has a flat surface 6a. The coating 6 has a rectangular configuration complementary to the configuration of the flanges 1b.

  • Patent number: 5669134
    Abstract: A winding core is formed by extruding a kneaded material which is obtained by kneading a powdered magnetic material and a binder. A conducting wire is wound around the winding core in a coiled manner. An external cover element is formed by extruding the kneaded material to enclose the winding core, and the winding core and the external cover element are sintered. The semimanufactured product obtained by the above steps is cut into a predetermined length to thereby obtain a plurality of chip inductor main bodies. An external electrode is formed on each of end surfaces of the respective chip inductor main bodies such that the external electrode is connected to each of end portions of the conducting wire, the end portions being exposed to both end surfaces of the respective chip inductor main bodies.
