Patent number: 11342111Abstract: A first filler resin is disposed to cover at least an outer peripheral side of a secondary spool and a secondary coil. The second filler resin is filled inside a case and seals a cover sealant which includes a primary coil, secondary spool, a secondary coil, a center core, an outer core and the first filler resin. The connector protrudes to an outside of the case. The case has a fixing portion. The second filler resin has a lower elasticity than the first filler resin. The ignition coil is manufactured by filling the first resin inside the case, and filling the second resin after the first resin is cured.Type: GrantFiled: June 8, 2017Date of Patent: May 24, 2022Assignee: DENSO CORPORATIONInventor: Atsuyuki Konishi

Patent number: 6809621Abstract: An ignition coil (1) having a case (2), a core (22) installed in the case, a primary spool (25) disposed substantially coaxially around an outer circumference of the core within the case, a primary coil (26) comprising a wire wound around the primary spool, a secondary spool (23) disposed substantially coaxially around the outer circumference of the core within the case, a secondary coil (24) comprising a wire wound around the secondary spool and a resin insulating material (5) filled within the case, the ignition coil being characterized in that the spool of the primary and the secondary spools which is disposed between the secondary coil and the core and/or which is disposed between the secondary coil and the primary coil comprises a base resin having an adhesive strength to the resin insulating material which is less than that provided by polybutylene terephthalate and an insulation breakdown voltage which exceeds that provided by polyphenylene sulfide.Type: GrantFiled: January 29, 2003Date of Patent: October 26, 2004Assignee: Denso CorporationInventors: Takashi Nagata, Kazutoyo Osuka, Atsuyuki Konishi, Kazuhide Kawai, Junichi Wada

Patent number: 6675786Abstract: In an ignition coil assembly, a plurality of ignition coils is arranged to be electrically connected to spark plugs received in plug holes of an engine. A base cover supports the ignition coils at corresponding positions, which correspond to positions of the plug holes, respectively. A top cover covers a top surface of the base cover. Connecting bolts connects between the top cover and the base cover. Fastening bolts secures only the base cover to the engine.Type: GrantFiled: June 11, 2003Date of Patent: January 13, 2004Assignee: Denso CorporationInventors: Koji Tsunenaga, Atsuyuki Konishi

Patent number: 6662794Abstract: An ignition coil according to the invention is an ignition coil having a case and a coil portion accommodated in the case. The case comprises a base resin whose dielectric breakdown voltage exceeds that of polyphenylene sulfide and whose spiral flow length exceeds that of polybutyrene terphthalate. As the base resin has a high fluidity, there is only a limited risk that a defect such as a weld line is caused when molding a thin case. In addition, while the thickness of the case and the electrical insulation properties are in proportion to each other, the case comprising the base resin can ensure sufficient electrical insulation properties even if the case is formed thin.Type: GrantFiled: May 31, 2002Date of Patent: December 16, 2003Assignee: Denso CorporationInventors: Takashi Nagata, Kazutoyo Osuka, Atsuyuki Konishi, Junichi Wada

Patent number: 6653922Abstract: An ignition coil includes a housing which contains a central core portion, an inner spool having a first winding, and an outer spool having a second winding. The inner spool extends outward of the central core portion. The outer spool extends outward of the inner spool. A locating member includes a locating rib adjacent to an upper portion of the central core portion. The locating rib is in a gap between the inner spool and the central core portion, and locates the inner spool and the central core portion relative to each other. Insulating resin injected into the housing provides insulation among parts in the housing. At least one of the inner spool and the locating member has a void-escape passage which connects the gap and an outside of the inner spool with each other, and which allows a void to escape from the injected insulating resin in the gap.Type: GrantFiled: June 27, 2002Date of Patent: November 25, 2003Assignee: Denso CorporationInventors: Masafuyu Sano, Kazutoyo Osuka, Norihiro Adachi, Yoshihiro Shimoide, Osamu Sugie, Kaneo Buma, Katsunori Akimoto, Atsuyuki Konishi, Masaharu Shimohata, Yoshitaka Sato
