336216000 | CORE JOINT STRUCTURE | 6 |
20080224813 | WIRE-WOUND COIL - A wire-wound coil includes a ferrite core having a winding core portion and flange portions, a wire wound around the winding core portion, electrodes connected to the wire on lower surfaces of the flange portions, and a ferrite plate attached to upper surfaces of both of the end flange portions so as to extend over the winding core portion. The flange portions and the ferrite plate are provided with corresponding recessed and projecting portions and, and the flange portions and the ferrite plate are integrated through the recessed and projecting portions. Joint sections between the flange portions and the ferrite plate include contact sections that are in direct contact with each other, and adhesion sections arranged to receive an adhesive. | 09-18-2008 |
20080290983 | CORE ASSEMBLY, IN PARTICULAR FOR AN IGNITION COIL OF AN INTERNAL COMBUSTION ENGINE - An ignition coil for an internal combustion engine includes a core assembly. The core assembly has a magnetically active core made of sheet-metal strips, a damping element and a sheath surrounding the core and the damping element. Different ways are described for improving the discharge of air trapped in the core assembly during casting of the ignition coil. For example, the damping element is designed with a V-shaped incision or a semipermeable diaphragm. | 11-27-2008 |
20090273431 | Lower cost continuous flux path transformer core and method of manufacture - In a continuous flux path transformer core, at least part of the core is implemented in non-grain oriented steel. | 11-05-2009 |
20100085138 | CROSSED GAP FERRITE CORES - The invention relates to swinging inductors of a stepped-gap construction. We describe an inductor core structure having first and second core segments, constructed and arranged such that distal ends of legs of the first core segment are paired with distal ends of legs of the second core segment in an opposing relation. The at least one distal ends of the first core segment has a ridge projecting therefrom and is paired with the at least one distal ends of the second core segment which has a ridge projecting therefrom in an opposing relation, such that opposingly paired projecting ridges form a cross arrangement. | 04-08-2010 |
20110234359 | REACTOR AND METHOD FOR MANUFACTURING REACTOR - A reactor includes: a first core having end surfaces; a second core having end surfaces facing the end surfaces of the first core; coils wound around at least part of the circumference of the first core and the second core; and gap members arranged between the end surfaces of the first core and the end surfaces of the second core. The coils and the gap members are integrally molded with a first resin in a state where the first and second cores are not provided. The coils and the first and second cores are integrally molded with a second resin in a state where the gap members are sandwiched between the end surfaces of the first core and the end surfaces of the second core. | 09-29-2011 |
20140266555 | MAGNETIC COMPONENT ASSEMBLY WITH FILLED GAP - Magnetic component assemblies for circuit boards include magnetic cores formed with a gap and preformed conductive windings sliding assembled to the cores via the gaps. The gaps in the cores are filled with a magnetic material to enhance the magnetic performance. The magnetic component assemblies may define power inductors. | 09-18-2014 |
