摘要:
An ignition coil has an ignition coil housing having a core and coil forms situated within it. In order to fill in the gaps between the components in the ignition coil housing using a cast resin used as insulation, the invention provides to introduce the latter either by a hollow needle or a riser directly into the bottom region of the ignition coil housing. The method described herein allows for a homogeneous material distribution of the cast resin and avoids inclusions of foreign particles or gases in the ignition coil housing.

A magnetic circuit for an ignition coil or a transformer, including an inner, essentially rod-shaped core and an outer core. The outer core includes a strip-shaped element of thickness, length and width, and is situated around the inner core in such a way that the strip-shaped element is positioned at the faces of the inner core with its thickness perpendicular to the longitudinal direction of the inner core.

An ignition coil for an internal combustion engine has a core, which is provided with a plastic extrusion coat on its periphery. The core is concentrically surrounded by a secondary coil and a primary coil. The plastic extrusion coat of the core is used as a coil shell for the secondary coil so that it is possible to dispense with a separate secondary coil shell. The ignition coil therefore has an especially compact design.

An ignition coil for an internal combustion engine has a secondary coil shell and a primary coil shell, which are positioned concentrically about a core and produced from plastic by injection molding methods. To avoid damage to the wire, at least the secondary coil shell is configured in such a way that it has no mold offset and no burrs in its winding region for the wire, which is achieved by providing separation planes extending transversely to the longitudinal axis.

An ignition coil for an internal combustion engine has a core, about which a secondary coil shell and a primary coil shell are concentrically positioned. The spaces between the core, the secondary coil shell, and the primary coil shell are filled in by an encapsulating material. The core is made up of lamellar, magnetic steel sheets. To compensate for stresses resulting from the different thermal expansion coefficients of the components, an elastic layer is situated between at least two of the magnetic steel sheets of the core.

An ignition coil for an internal combustion engine has a rod-shaped magnetic core, which is situated within a secondary coil shell. The annular interspace between the magnetic core and the secondary coil shell is filled with an electrically insulating molded material. To prevent the formation of tears in the molded material during thermo-mechanical loading, or the spread of such tears such that the operativeness of the ignition coil is adversely affected, a separation element is provided, which divides the molded material into at least two mutually separate regions.

An ignition coil arrangement for internal combustion engines is embodied so that a housing of an individual ignition coil can be produced economically, and attachment of the ignition coil can be accomplished easily. The ignition coil is configured as a rod-type ignition coil, and the housing is of basically cylindrical shape, since a holding element for fastening the ignition coil is configured in the high-voltage output of the ignition coil itself. Assembly and retention of the ignition coil are accomplished by a direct threaded connection on the high-voltage terminal of a spark plug. For rotational immobilization, a primary terminal of the ignition coil is coupled to a fastenable mating plug as a joining member. The ignition coil arrangement is preferably used in motor vehicles.

Proposed is a pencil ignition coil including a rod core (14), a first coil form (16) having a first coil winding (18), and a second coil form having a second coil winding (26). In accordance with the present invention, the second coil form is formed by an assembly including the first coil form (16), the first coil winding (18), and a potting compound (24) for the first coil winding (18) (FIG. 4).
