Aus der
Das erfindungsgemäße Verfahren zum Herstellen einer Spule, insbesondere einer Zündspule für ein Kraftfahrzeug mit den Merkmalen des Anspruchs 1 hat den Vorteil, dass es bei Reduzierung des Bauraums durch den Verzicht auf einen separaten Primärspulenkörper eine einfache und kostengünstige Herstellung ermöglicht.The inventive method for producing a coil, in particular an ignition coil for a motor vehicle with the features of claim 1 has the advantage that it allows for reducing the space by the waiver of a separate primary spool a simple and inexpensive production.
Vorteilhafte Weiterbildungen des erfindungsgemäßen Verfahrens sowie eine Vorrichtung zum Durchführen des erfindungsgemäßen Verfahrens sind in den Unteransprüchen aufgeführt.Advantageous developments of the method according to the invention and a device for carrying out the method according to the invention are listed in the subclaims.
Um eine möglichst einfache Kontaktierung der Enden der Primärwicklung mit den die Primärwicklung in der Spule kontaktierenden Bauteilen zu ermöglichen, ist es in einer erfindungsgemäßen Weiterbildung vorgesehen einen Anschlussring vorzusehen, welcher vorab mit den Enden der Primärwicklung verbunden wird und zusammen mit dem Wickeldorn in das Gehäuse der Spule eingeführt wird.In order to allow the simplest possible contacting of the ends of the primary winding with the primary winding in the coil contacting components, it is provided in a development of the invention to provide a connection ring, which is connected in advance with the ends of the primary winding and together with the winding mandrel in the housing Coil is inserted.
Um eine bessere elektrische Isolierung zwischen der Sekundärwicklung und der Primärwicklung zu ermöglichen, ist es weiterhin verteilhaft, zwischen der Primärwicklung und der Sekundärwicklung eine Zwischenschicht vorzusehen, welche bereits vor dem Aufwickeln der Primärwicklung auf dem Wickeldorn auf den Wickeldorn aufgebracht wird.In order to allow a better electrical insulation between the secondary winding and the primary winding, it is further distributive to provide an intermediate layer between the primary winding and the secondary winding, which is already applied to the winding mandrel before winding the primary winding on the winding mandrel.
Besonders gute Isolationseigenschaften erreicht man ferner, wenn das Gehäuse bzw. die Zwischenräume im Gehäuse nach der Montage der einzelnen Bauteile mit einem Isolierharz befüllt werden.Particularly good insulation properties are also achieved if the housing or the interstices in the housing are filled after assembly of the individual components with an insulating resin.
Um ein besonders gutes Überführen bzw. Abstreifen der Primärwicklung im Gehäuse der Spule zu ermöglichen, ist es in einer weiteren vorteilhaften Ausführungsform vorgesehen, ein zusätzliches Abstreifelement vorzusehen, das die Primärwicklung hält bzw. fixiert, wenn der Wickeldorn aus dem Gehäuse der Spule herausgezogen wird.In order to allow a particularly good transfer or stripping of the primary winding in the housing of the coil, it is provided in a further advantageous embodiment to provide an additional stripping element that holds the primary winding or fixed when the winding mandrel is pulled out of the housing of the coil.
Anstelle eines Abstreifelements ist es auch denkbar, den Wickeldorn mit einem variablen Durchmesser vorzusehen, derart, dass zum Herausziehen des Wickeldorns der Durchmesser des Wickeldorns verkleinert wird, so dass die Haftung bzw. Bindung zwischen dem Wickeldorn und der Primärwicklung beim Herausziehen des Wickeldorns aus dem Gehäuse aufgehoben wird.Instead of a stripping element, it is also conceivable to provide the winding mandrel with a variable diameter, such that for pulling out of the winding mandrel, the diameter of the winding mandrel is reduced so that the adhesion or bond between the winding mandrel and the primary winding when pulling out the winding mandrel from the housing will be annulled.
