Description
Die Erfindung betrifft eine elektrische Verbindungsanordnung zur Herstellung einer Zündspule, insbesondere einer Stabzündspule mit einem Spulenkörper mit einem Hochspannungsabgang sowie einem Niederspannungsabgang.The invention relates to an electrical connection arrangement for producing an ignition coil, in particular a pencil ignition coil with a bobbin with a high-voltage outlet and a low-voltage outlet.
Zündspulen erzeugen Hochspannungsfunken. Dieser springt bei der an der Zündspule angeordneten Zündkerze an deren Elektroden über und zündet so beispielsweise das Luft-Benzin-Gemisch einer Brennkraftmaschine. In der Regel wird diese Zündkerze mit einer Zündspule mit Hochspannung versorgt. Innerhalb der Zündspule ist eine Primärwicklung und eine entsprechende Sekundärwicklung vorgesehen. Die Primärwicklung ist mit ihrem einen Ende an einen Zündanlassschalter gekoppelt, wobei ihr anderes Ende mit einem sogenannten Unterbrecher verbunden ist.Ignition coils generate high voltage sparks. This jumps at the arranged on the ignition coil spark plug at the electrodes and thus ignites, for example, the air-fuel mixture of an internal combustion engine. As a rule, this spark plug is supplied with an ignition coil with high voltage. Within the ignition coil, a primary winding and a corresponding secondary winding is provided. The primary winding is coupled at one end to an ignition starter switch, with its other end connected to a so-called breaker.
Die Sekundärwicklung, also die Wicklung, die für die Entstehung des Zündfunkens verantwortlich ist, ist im Inneren der Zündspule mit dem einen Ende der Primärwicklung verbunden, so dass diese an Masse liegt. Das andere Ende der Sekundärwicklung ist mit dem Hochspannungsabgang verbunden, der wiederum entweder mit einem Zündkabel, das zur Zündkerze führt, verbunden ist oder an dem unmittelbar die Zündkerze angeordnet ist.The secondary winding, so the winding, which is responsible for the formation of the spark, is inside the ignition coil with the one Connected to the end of the primary winding so that it is grounded. The other end of the secondary winding is connected to the high voltage output, which in turn is either connected to an ignition cable leading to the spark plug, or to which the spark plug is located directly.
Die Sekundärwicklung selbst besteht aus einem dünnen Draht, der mit einer entsprechenden Lackschicht überzogen ist, um bei der Umwicklung des Spulenkörpers die Kontaktierung der einzelnen Drähte zu vermeiden. Nachdem die Sekundärwicklungen auf dem Spulenkörper gewickelt worden sind, werden die Enden der jeweiligen Drähte kontaktiert. Hierzu sind in der Regel thermische Kontaktierungsverfahren bekannt, beispielsweise Löten oder Schweißen.The secondary winding itself consists of a thin wire, which is coated with a corresponding lacquer layer in order to avoid the contacting of the individual wires during the winding of the bobbin. After the secondary windings are wound on the bobbin, the ends of the respective wires are contacted. For this purpose, thermal contacting methods are generally known, for example soldering or welding.
Aus der
Insbesondere bezüglich der Kontaktierung von Primär- und Sekundärwicklung sind unterschiedliche Arbeitsprozesse notwendig. Dies erfordert höhere Anlagekosten, mehrere Montageschritte und auch eine bestimmte Anzahl von Anschlussteilen, die notwendig sind, um eine elektrische Verbindung entsprechend herstellen zu können.In particular, with respect to the contacting of primary and secondary winding different work processes are necessary. This requires higher installation costs, several assembly steps and also a certain number of connection parts, which are necessary in order to be able to produce an electrical connection accordingly.
Zudem gestaltete es sich oft schwierig, auf sehr engem Bauraum hier eine entsprechende Kontaktierung mittels den bekannten thermischen Verfahren herbeizuführen.In addition, it was often difficult to bring about a very close space here a corresponding contact using the known thermal processes.
Die Aufgabe der Erfindung ist es, eine Verbindungsanordnung an einer Sekundär- bzw. Primärwicklung herzustellen, die kostengünstig und einfach realisierbar ist.The object of the invention is to produce a connection arrangement on a secondary or primary winding, which is inexpensive and easy to implement.
Das Grundprinzip der Lösung der Aufgabe besteht darin, das an sich aus dem Stand der Technik bekannte thermische Kontaktierungsverfahren zu ersetzen. Dies erfolgt dadurch, dass zusätzliche Kontaktierungselemente geschaffen worden sind, die bei der Montage den mit Lack ummantelten Draht der Sekundärwicklung durchbrechen und so eine entsprechende Kontaktierung herbeiführen.The basic principle of the solution of the problem is to replace the known from the prior art thermal bonding method. This is done by adding additional contacting elements have been created, which break during installation coated with lacquer wire of the secondary winding and thus bring about a corresponding contact.
Die Lösung der Aufgabe wird durch die Merkmale von Anspruch 1 vorgeschlagen.The solution of the problem is proposed by the features of claim 1.
Das hier vorgeschlagene "kalte" Kontaktierungsverfahren hat gegenüber dem bisherigen Verfahren den Vorteil, dass keine zusätzlichen Anlagekosten notwendig sind. Ferner reduzieren sich zusätzlich Montageschritte und auch eine Reduzierung von Ausschlussteilen kann durch die erfindungsgemäße Ausführung verzeichnet werden.The "cold" contacting method proposed here has the advantage over the previous method that no additional system costs are necessary. Furthermore, additional assembly steps are reduced and also a reduction of exclusion parts can be recorded by the embodiment according to the invention.
Ein weiterer wesentlicher Vorteil der Erfindung besteht darin, dass für die Durchführung der Kontaktierung keine Bauraumoptimierung erfolgen muss. Dies bedeutet, dass kein Freiraum im Bereich der Kontaktierung z.B. für Schweißzangen, Lötkolben oder dergleichen vorgehalten werden muss.Another essential advantage of the invention is that no space must be optimized for carrying out the contacting. This means that there is no free space in the area of contacting e.g. must be kept for welding tongs, soldering iron or the like.
Auf der Seite des Niederspannungsabgangs ist erfindungsgemäß vorgesehen, ein Kontaktelement über Führungsmittel einzuschieben. Das Kontaktelement ist derart gestaltet, dass das eine Ende in Schieberichtung tulpenartig aufgefächert ist und so während des Aufschiebens über die Primärwicklung, die auf dem Spulenkörper angeordnet ist, gleitet. Das andere Ende ist derart ausgebildet, dass es in einer Tasche fixierbar ist.On the side of the low-voltage outlet, it is provided according to the invention to insert a contact element via guide means. The contact element is designed such that the one end is fanned tulip-like in the sliding direction and thus slides during the sliding over the primary winding, which is arranged on the bobbin. The other end is designed such that it can be fixed in a pocket.
Um hier eine bessere Gleiteigenschaft vorzuweisen, weist das Kontaktelement zusätzlich eine Gleitfläche auf, die zu der Primärwicklung hinweist.In order to present a better sliding property here, the contact element additionally has a sliding surface, which points to the primary winding.
Durch das Aufsetzen eines Primärspulenkörpers zumindest über einen Teil des Sekundärspulenkörpers wird das freie Ende des Kontaktelements mit seiner Gleitfläche durch eine Nase, die innerhalb des Primärspulenkörpers angeordnet ist, niedergedrückt.By placing a primary coil body at least over a part of the secondary coil body, the free end of the contact element with its sliding surface by a nose which is disposed within the primary coil body, depressed.
Bei Erreichen einer definierten Stellung drückt das Kontaktelement mit seiner Gleitfläche gegen die mit Isolierung versehenen Drähte des Sekundärspulenkörpers, wodurch die Isolierung an den entsprechenden Kontaktstellen aufgebrochen wird, so dass ein elektrischer Kontakt zwischen den einzelnen Drähten des Sekundärspulenkörpers und dem Kontaktelement herstellbar ist.Upon reaching a defined position, the contact element presses with its sliding surface against the insulated wires of the secondary coil body, whereby the insulation is broken at the corresponding contact points, so that an electrical contact between the individual wires of the secondary coil body and the contact element can be produced.
Bevorzugt ist das Kontaktelement derart ausgebildet, dass es zur Erlangung seiner mechanischen federartigen Eigenschaften eine Taille aufweist.Preferably, the contact element is designed such that it has a waist to achieve its mechanical spring-like properties.
Insbesondere auf der Seite des Hochspannungsabgangs ist vorgesehen, die erfindungsgemäß ausgestalteten Kontaktelemente zu einer Kontaktkrone zusammenzufassen. Hierbei werden die einzelnen erfindungsgemäßen Kontaktelemente auf ihrer von der Gleitfläche wegweisenden Seite an einem Ringelement fixiert. Bevorzugt besteht diese Kontaktkrone aus einem einstückigen Teil, wobei vorstellbar ist, dass die Kontaktkrone in einem einzigen Arbeitsgang (Stanzen und Biegen) herstellbar ist.In particular, on the side of the high-voltage outlet, it is provided to combine the contact elements designed according to the invention to form a contact crown. Here, the individual contact elements according to the invention are fixed on their side facing away from the sliding surface side on a ring member. Preferably, this contact crown consists of a one-piece part, it being conceivable that the contact crown in a single operation (punching and bending) can be produced.
Während des Aufschiebens der Kontaktkrone auf die Sekundärwicklungen gleiten die einzelnen Kontaktelemente auf der Oberfläche der Wicklung. Durch die tulpenartige Ausgestaltung der Kontaktkrone wird vermieden, das die Wicklungen verschoben oder beschädigt werden. Durch einen Anschlag, der gleichzeitig Aufnahme des Endes der Sekundärwicklung in der Ausbildung eines Anbindepfostens ist, ist die Position der Kontaktkrone definiert. Dies wird auch dadurch bewirkt, dass der Durchmesser der Kontaktkorne größer ist als der Sekundärspulenkörper plus zweimal der Durchmesser der Sekundärwicklung.During the sliding of the contact crown on the secondary windings slide the individual contact elements on the surface of the winding. The tulip-like configuration of the contact crown avoids that the windings are moved or damaged. By a stop which is at the same time receiving the end of the secondary winding in the formation of a Anbindepfostens, the position of the contact crown is defined. This is also caused by the fact that the diameter of the contact beads is larger than the secondary coil body plus twice the diameter of the secondary winding.
In einem weiteren Schritt wird ein Ringelement über die Kontaktkrone geschoben, durch die ein Presssitz des Kontaktelements auf der Sekundärwicklung und damit ein Kontaktieren der Kontaktelemente der Kontaktkrone mit der Sekundärwicklung erreicht wird.In a further step, a ring element is pushed over the contact crown, by which an interference fit of the contact element on the secondary winding and thus contacting the contact elements of the contact crown is achieved with the secondary winding.
