Description

Zündspule mit Eisenschluß für Batteriezündeinrichtungen an Verbrennungsmotoren. Die Erfindung betrifft eine Zündspule für Batteriezündeinrichtungen, die trotz günstiger Ausbildung des Eisenschlusses eine einfache Herstellung gestattet. Bekanntlich ist bei Zündspulen einvollkommen eisengeschlossener Kraftlinienpfad nicht günstig, sondern es soll in diesem ein Luftspalt angeordnet sein, dessen Größe durch die vorliegenden Verhältnisse bestimmt ist. Diese Verhältnisse sind im allgemeinen derart, daß der Luftspalt sehr klein gemacht werden muß. Dies bringt aber Herstellungsschwierigkeiten mit sich, weil die einzelnen Teile des Eisenweges sehr maßgenau hergestellt und zusammengebaut werden müssen.Ignition coil with iron connection for battery ignition devices on internal combustion engines. The invention relates to an ignition coil for battery ignition devices, which despite being cheaper Formation of the iron connection allows simple manufacture. It is well known In the case of ignition coils, a completely iron-closed force line path is not favorable, but rather it should be arranged in this an air gap, the size of the present Relationship is determined. These relationships are generally such that the Air gap must be made very small. But this brings manufacturing difficulties with itself, because the individual parts of the Eisenweg are made to measure and need to be assembled.

Bei der Erfindung wird deshalb von dein an sich bereits bekannten Mittel Gebrauch gemacht, den Luftspalt gegenüber dem mittleren Eisenquerschnitt zu vergrößern. Dadurch kann der Widerstand des Luftspalts genügend klein gehalten und der Luftspalt selbst doch so groß gemacht werden, daß keine allzu große Arbeitsgenauigkeit notwendig wird.The invention is therefore of your already known Means made use of the air gap against the mean iron cross-section to enlarge. As a result, the resistance of the air gap can be kept sufficiently small and the air gap itself can be made so large that the work accuracy is not too great becomes necessary.

Die Erfindung besteht darin, der Zündspule einen Kern von H-Form zu geben und als Eisenschluß einen vollkommen geschlossenen Eisenring zu verwenden, dessen Innenumfang den Enden des Kerns in einem bestimmten Abstand gegenübersteht. Auf der Zeichnung ist eine beispielsweise Ausführungsform des Erfindungsgegenstandes durch Abb. i im Längsschnitt und durch Abb. a in Seitenansicht wiedergegeben. Ein Kern a, der die Spule b trägt, ist an den Stirnflächen mit Ansätzen c versehen, so daß .er im Längsschnitt die bekannte H-Form bekommt. Der äußere Eisenschluß wird durch einen vollkommen geschlossenen Eisenring d hergestellt, der den nach einem konzentrischen Kreisbogen geformten Außen-. fiächen der Ansätze c gegenüberliegt.The invention consists in giving the ignition coil an H-shaped core and to use a completely closed iron ring as an iron lock, whose inner circumference faces the ends of the core at a certain distance. The drawing shows an example of an embodiment of the subject matter of the invention reproduced by Fig. i in longitudinal section and by Fig. a in side view. A Core a, which carries the coil b, is provided with lugs c on the end faces, so that it gets the familiar H-shape in a longitudinal section. The outer iron connection is produced by a completely closed iron ring d which, after a concentric circular arc shaped outer. faces of the approaches c is opposite.

Durch die Verbreiterung der Kernstirnflächen wird der Querschnitt des Luftspalts e im Kraftlinienpfad vergrößert, und der Luftspalt 2 braucht infolgedessen nicht so klein gemacht zu werden, däß er nur schwer genau herzustellen wäre.By widening the core end faces, the cross-section becomes of the air gap e increases in the force line path, and the air gap 2 needs as a result not to be made so small that it would be difficult to manufacture accurately.
