Abstract

The connection piece (15) of epoxy resin with the contact element (18) is provided with an annular sealing element (19) made of an elastomer with a U-shaped groove (24). The pot-shaped casing (10) has a U-shaped rim (27) in which the groove (24) can be slid, so that the connection piece (15) is secured to the casing (10) by a type of groove-spring joint. The inner space of the casing (10) is filled with a pourable compound (20). In this way a high-voltage connection (18) transverse to the axis (14) of the ignition coil is obtained.

Description

Zündspule für Zündanlagen von BrennkraftmaschinenIgnition coil for ignition systems of internal combustion engines
Stand der TechnikState of the art
Die Erfindung betrifft eine Zündspule für Zündanlagen von Brenn- kraftmaschinen nach der Gattung des Anspruchs 1. Der Anschlußteil aus Isolierstoff mit dem Hochspannungs-Kontaktelement von ausgeführ¬ ten Zündspulen dieser Gattung ist bezüglich der Zündspulen-Achse im wesentlichen parallel angeordnet und ragt aus der mit Isoliermasse vergossenen Öffnung des Gehäuses. Die Unterbringung derartiger Zünd¬ spulen im Motorraum ist jedoch problematisch, so daß eine seitliche Anordnung quer zur Achse verlangt wird.The invention relates to an ignition coil for ignition systems of internal combustion engines. The connecting part made of insulating material with the high-voltage contact element of executed ignition coils of this type is arranged essentially parallel with respect to the ignition coil axis and protrudes from the insulating compound potted opening of the housing. However, the accommodation of such ignition coils in the engine compartment is problematic, so that a lateral arrangement transverse to the axis is required.

Es zeigen: Figur 1 die Zündspule für Zündanlagen von Brennkraftmaschinen in ab¬ schnittsweiser Seitenansicht und natürlicher Größe; Figur 2 ab¬ schnittsweise die Zündspule in raumbildlicher, unmaßstäblicher Dar¬ stellung gemäß Blickrichtung Pfeil II in Figur 1 ; und Figur 3 einen abschnittsweisen Querschnitt im Bereich der Nut-Feder-Verbindung mit einer Sicherung gegen das Aufspreizen des Gehäuses.An embodiment of the invention is shown in the drawing and explained in more detail in the description of the figures. FIG. 1 shows the ignition coil for ignition systems of internal combustion engines in partial side view and natural size; FIG. 2 shows sections of the ignition coil in a spatial representation, not to scale, in the direction of view arrow II in FIG. 1; and FIG. 3 shows a cross section in sections in the area of the tongue and groove connection with a safeguard against the housing being spread open.
Beschreibung des AusführungsbeispielesDescription of the embodiment
Eine Zündspule für Zündanlagen von Brennkraftiαaschinen hat ein topf- förmiges Gehäuse 10 aus dem thermoplastischen Kunststoff Poly- butylenterephtalat (PBTB) mit 30 Prozent Glasfasern. Von einem mehr- schenkligen Kern 11 aus magnetisch leitfähigen Eisenblechen ragt ein Schenkel 12 mit einer Primärwicklung und einer Sekundärwicklung (beide nicht sichtbar) in das Innere des Gehäuses 10; aus diesem ragt parallel zur Achse 14 der Zündspule ein Primäranschlußteil 3.An ignition coil for ignition systems of internal combustion engines has a pot-shaped housing 10 made of the thermoplastic polybutylene terephthalate (PBTB) with 30 percent glass fibers. A leg 12 with a primary winding and a secondary winding (both not visible) protrudes from a multi-legged core 11 made of magnetically conductive iron sheets into the interior of the housing 10; from this protrudes a primary connection part 3 parallel to the axis 14 of the ignition coil.
Ein Sekundär-Anschlußteil 15 aus Polyester hat einen zur Achse 14 parallelen Flansch 16 und eine Tülle 17 mit einem Kontaktelement 18 für den Hochspannungsanschluß. Im Flansch 16 ist ein ringförmiges Dichtelement 19 aus einem Elastomer befestigt. Das den Schenkel 12 des Kernes 11 mit der Primärwicklung und Sekundärwicklung aufnehmen¬ de Gehäuse 10 ist mittels der isolierenden Vergußmasse Epoxyd-Harz 20 gefüllt, das gleichzeitig den Anschiußteil 15 mit dem Gehäuse 10 isolierend abdichtet.A secondary connecting part 15 made of polyester has a flange 16 parallel to the axis 14 and a grommet 17 with a contact element 18 for the high-voltage connection. In the flange 16 is an annular Sealing element 19 attached from an elastomer. The housing 10 receiving the leg 12 of the core 11 with the primary winding and secondary winding is filled by means of the insulating potting compound epoxy resin 20, which at the same time seals the connection part 15 with the housing 10 in an insulating manner.
Gemäß Figur 2 sind ir. der Stirnfläche des Flansches 16 vom Anschlu߬ teil 15 eine U-fδrmige Rille 21 und eine deren Ende verbindende Ver¬ tiefung 22 ausgespart;. Das Dichtelement 19 hat einen in die Vertie¬ fung 22 eingreifenden Steg 25 und einen Abschnitt 26 mit einer U-förmigen Nut 24 mit zwei einander zugewandten Dichtlippen 23. Der Abschnitt 26 ist in der Rille 21 eingelegt. Eine Aussparung im Ge¬ häuse 10 bildet einen U-förmigen Rand 27, der mit der Nut 24 nach Art einer Nut-reder-Verbindung zusammenwirkt. Die zwei einander zu¬ gewandten Dichtlippen 23 des Abschnittes 26 werden durch den Rand 27 an die Wände der Rille 21 gepreßt und dichten dadurch das eingefüll¬ te Gießharz 20 ab.According to FIG. 2, a U-shaped groove 21 and a recess 22 connecting the end of the flange 16 are recessed from the connecting part 15. The sealing element 19 has a web 25 engaging in the recess 22 and a section 26 with a U-shaped groove 24 with two sealing lips 23 facing each other. The section 26 is inserted in the groove 21. A recess in the housing 10 forms a U-shaped edge 27 which cooperates with the groove 24 in the manner of a groove-speaker connection. The two mutually facing sealing lips 23 of section 26 are pressed by the edge 27 against the walls of the groove 21 and thereby seal the filled casting resin 20.
Figur 3 zeigt abschnittsweise die Alternative zu Figur 2 mit dem Se¬ kundäranschlußteil 35t dessen Flansch 36 zwei seitliche Haken 32 aufweist (nur einer dargestellt), wobei jeder Haken 32 eine vom Ge¬ häuse 30 nach außen abstehende Schiene 31 hintergreift. Durch dieses Hintergreifen wird ein seitliches Aufspreizen des Gehäuses 30 ver¬ mieden. FIG. 3 shows in sections the alternative to FIG. 2 with the secondary connection part 35 t, the flange 36 of which has two lateral hooks 32 (only one shown), each hook 32 engaging behind a rail 31 projecting outwards from the housing 30. By this reaching behind a lateral spreading of the housing 30 is avoided.
