摘要： An ignition coil includes primary and secondary coils, a center core inserted into a center hole of the primary coil and a center hole of the secondary coil, an annular side core that forms a magnetic circuit through which a first magnetic flux A generated by the primary coil by being joined to the center core permeates, and a permanent magnet that is disposed between the center core and the side core and that emits a second magnetic flux B directed opposite to the first magnetic flux A to apply a magnetic bias. The side core includes protruded portions that protrude towards lateral sides of a T-shaped horizontal portion of the center core, and gaps are provided between the lateral sides of the T-shaped horizontal portion of the center core and the protruded portions of the side core.

摘要： A high-strength ignition coil that can prevent distortion arising from pin marks formed on a surface of a core and makes it less likely for insulating resin to be cracked. The coil assembly is housed in a coil case. A casting material is filled into a gap between the coil case and the coil assembly and gaps which the coil assembly has. The coil assembly is comprised of a coil pair including a cylindrical primary coil and a secondary coil disposed concentrically with the primary coil, and a core. The core is fitted into a central space of the coil pair and forms a magnetic path. The core is coated with mold resin. Concave portions of pin marks formed on a mold resin coating by removal of core fixing pins when the mold resin coating is formed are filled with mold resin.

摘要： An ignition coil, in particular for an internal combustion engine of a motor vehicle, has an inner magnet core, which is concentrically surrounded by a primary coil and a secondary coil. The inner magnet core acts together with an outer C-shaped magnet core. To minimize the size of the ignition coil, a provision is made in particular to adapt the height of the outer magnet core to the height of the secondary coil. It is furthermore provided to develop the outer magnet core from multiple sheet metal elements, which may be manufactured by a punching/bending process. This makes it possible to achieve a particularly cost-effective manufacture.

摘要： An ignition coil is constructed of a center core, a primary coil, a secondary coil, and an outer circumferential core. The center core and the outer circumferential core are connected with each other via a first magnetoresistive member on one axial end side. The center core and the outer circumferential core are connected with each other via a second magnetoresistive member on the other axial end side. A permanent magnet is arranged in an axially central portion of the center core. A magnetic passage is formed of the center core, the permanent magnet, the first magnetoresistive member, the outer circumferential core, and the second magnetoresistive member. Magnetic flux generated by the primary coil is reduced through the first and second magnetoresistive members, and is reverse-biased by the permanent magnet.

摘要： An auxiliary core portion and a main core portion, including a magnet if the magnet is attached, are covered by a resin film or an elastomer film and fixed as a single assembly. In this state, a coil is attached to the assembly and a side core portion is assembled to the assembly. The auxiliary core portion and the main core portion, including the magnet if it is attached, can be supplied, as the single assembly, to an automated assembly line for ignition coils. It is not necessary to position such components on the assembly line. Thus, the workability of the automated assembly can be enhanced.
