Publication number: 20100321015Abstract: A method for producing a coil assembly includes overlaying printed circuit traces on a core. The traces include terminals for coupling to conductive connections on a base on which the coil assembly is to be mounted. Two or more wires are wrapped around the core so as to define two or more coils, wrapped in different, respective directions. The ends of the wires are coupled to the printed circuit traces, so as to connect the wires through the traces to the terminals.Type: ApplicationFiled: August 30, 2010Publication date: December 23, 2010Inventors: Pesach Susel, Shlomo Fried, Avi Shalgi, Dan Raz, Dror Benatav

Patent number: 7849843Abstract: An ignition coil is equipped with a sparkplug of an engine. The ignition coil includes a coil portion, a tower portion, and a plug cap. The coil portion includes a coil case accommodating a primary and secondary coils being coaxial with each other. The coil portion has an end connected with the plug cap via the tower portion. The plug cap is press-fitted with the sparkplug. The coil case has an outer periphery from which a flange portion projects radially outward in a flange-projecting direction. The tower cylinder portion has a tower axis substantially in parallel with a coil axis of the primary and secondary coils. The tower axis is offset from the coil axis in a tower-offset direction. The tower-offset direction is substantially the same as the flange-projecting direction.Type: GrantFiled: April 1, 2008Date of Patent: December 14, 2010Assignees: Denso Corporation, Toyo Denso Kabushiki KaishaInventors: Masami Kojima, Takashi Tauchi, Takeshi Morimoto, Atsushi Iwami, Yoshitaka Satoh, Shuichi Matsubayashi, Ikuo Hirayama
