Zündspuleignition coil

Die Neuerune bezieht sich auf Zündspulen für Kraftfahrzeuge. The new run relates to ignition coils for motor vehicles.

Infolge der sehr hohen Spannung, die in einer Zündspule erzeugt wird, ist die Isolation des Mittelkernes der Zündspule von größter Bedeutung. Bisher war es üblich, den Mittelkern auf einem Isolationskörper abzustützen, der aus Porzellan oder einem keramischen Material hergestellt war. Falls indessen ein Riss oder eine Blase im Isolationskörpe-* vorhanden war, konnte dieser Fehler erst bei der Abschlußprüfung der fertigen Zündspule festgestellt werden.As a result of the very high voltage that is generated in an ignition coil, the insulation of the central core is the ignition coil is of the utmost importance. So far it has been customary to support the central core on an insulating body made of porcelain or a ceramic material was. However, if there was a crack or a bubble in the insulation body *, this error could occur can only be determined during the final inspection of the finished ignition coil.

Die Neuerung stellt sich zur Aufgabe, diese Schwierigkeiten zu beseitigen.The innovation sets itself the task of eliminating these difficulties.

Diese Aufgabe wird dadurch gelöst, daß der Isolationskörper aus einem transparenten Material hergestellt ist.This object is achieved in that the insulating body is made of a transparent material.

Hierdurch ist die Möglichkeit gegeben, den Isolationskörper vor dem Zusammenbau einer Sichtkontrolle zu unterziehen. This makes it possible to subject the insulation body to a visual inspection before it is assembled.

Ein Ausführungsbeispiel soll anhand der beiliegenden Zeichnung näher erläutert werden, die eine Ansicht der Zündspule im Schnitt zeigt.An exemplary embodiment will be explained in more detail with reference to the accompanying drawing, which shows a view of the ignition coil shows in section.

Die Zündspule besteht aus einem hohlen Gehäuse 11, das an seinem unteren Ende geschlossen ist und das am oberen Ende von einem Isolierdeckel 12 abgeschlossen ist. Am Boden des Gehäuses 11 ist ein Isolationskörper 13 angeordnet, der aus einem transparenten Material hergestellt und in dessen Aussparung ein lameliierter Eisenkern 14 angeordnet ist. Den Kern umgibt ein zylindrischer Spulenträger, auf dem konzentrisch die Primär- und Sekundärspule aufgewickelt ist. Am Isolierdeckel 12 sind zwei Klemmen 16, 17 zusammen mit einer Hochspannungsklemme l8 angeordnet. Ein Ende der Primär- und der Sekundärspule ist mit der Klemme 16 verbunden, während das andere Ende der Primärspule an die Klemme 17 angeschlossen ist und das andere Ende der Sekundärspule über den Kern l4 an der Klemme 18 liegt. Der Anschluß zwischen dem Kern 14 und der Klemme 18 wird über eine Feder hergestellt.The ignition coil consists of a hollow housing 11, which is closed at its lower end and that at the top End of an insulating cover 12 is completed. An insulation body 13 is arranged on the bottom of the housing 11, which is made of a transparent material and a laminated iron core 14 is arranged in its recess is. The core is surrounded by a cylindrical bobbin, on which the primary and secondary coils are concentrically wound is. On the insulating cover 12, two terminals 16, 17 are arranged together with a high-voltage terminal l8. A End of the primary and the secondary coil is connected to the terminal 16, while the other end of the primary coil is connected to the terminal 17 is connected and the other end of the secondary coil is connected to the terminal 18 via the core 14. Of the Connection between the core 14 and the terminal 18 is made via a spring.

Der Isolationskörper 13 isoliert den Kern 14 gegenüber dem Gehäuse 11 und muß daher einer sehr hohen Spannung widerstehen, die im Betrieb zwischen dem Gehäuse 11 und dem Kern l4 auftritt.The insulation body 13 isolates the core 14 from the Housing 11 and must therefore withstand a very high voltage that is in operation between the housing 11 and the Core l4 occurs.

Vorzugsweise wird der Isolationskörper 13 aus Glas hergestellt, besonders gute Ergebnisse wurden hierbei mit Kronglas (Mondglas bzw. Solinglas) erzielt. Bei einem Zündsystem für 12 Volt muß das Glas einer Zündspannung von der Größenordnung von 35 KV widerstehen.The insulating body 13 is preferably made of glass, Particularly good results were achieved with crown glass (moon glass or soling glass). With an ignition system for 12 volts, the glass must withstand an ignition voltage of the order of 35 KV.
