Definitions
- the invention relates to a fastening arrangement for connections to ignition coils of motor vehicles according to the preamble of claim 1.
- Fastening arrangements in ignition coil housings in multi-spark ignition coils for connecting the primary windings of the ignition coils accommodated in the ignition coil housing are generally known.
- These fastening arrangements which are also referred to as busbars, form a structural plastic-molded unit with a connector and have two bare metal hooks per ignition coil to which the end sections of the primary windings are electrically contacted.
- the busbars are formed by metal strips with the hooks formed on the end and are inserted as insert parts in a plastic injection mold for producing the connector.
- busbars carry different electrical potentials during operation of the ignition coil, but the fastening arrangement should be constructed as space-saving as possible, the busbars must be positioned close to one another in the injection mold without touching each other, and fixed so that their starting position is not changed by the injection pressure becomes. This fastening arrangement is complex, expensive to produce and has high reject rates.
- the fastening arrangement according to the invention with the characterizing features of claim 1 has the advantage that the connection of the end sections of the primary coils with the connector is made via a circuit board that is easy to manufacture.
- This circuit board is functionally safer than the conductor rails and is made of glass fiber reinforced epoxy resin.
- the epoxy resin of the printed circuit board can be better connected to the casting resin than to the plastic-molded busbar. In view of the high temperature differences at the ignition coil when operating in a motor vehicle, this leads to improved resistance to aging of the ignition coil.
- FIG. 1 shows parts of the ignition coil with a two-part housing.
- the upper part of the housing is partially cut open and in the top view the lower part of the housing, partially cut, is shown with the fastening arrangement.
- Figure 2 shows the mounting arrangement in a side view and
- Figure 3 shows the mounting arrangement in a section along the line III-III of Figure 2.
- FIG. 1 shows part of an ignition coil 10 with a housing 11 and with a connector plug 12 partially protruding from the housing 11.
- the connector plug 12 forms a connector side 13 at one end, facing away from the housing 11, and a connector side 14 at its other end .
- connection side 14 From the connector side 13 to the connection side 14, three tongue-shaped contacts 16, which are electrically insulated from one another and which taper towards the connection side 14 towards pins 17, extend as electrical connection parts.
- the main connector 12 has, in addition to the metallic contacts 16, a sleeve 18 and a flange 19 as main components.
- the sleeve 18 is box-shaped and open to the connector side 13. It surrounds the contacts 16 on the connector side 13 with a joint play, so that coupling parts (not shown) of a mating connector can be pushed onto the contacts 16 between contacts 16 and collar 18.
- the sleeve 18 is closed to the connection side 14 on the inside by a base 21 which merges into the flange 19 which projects beyond the contour of the sleeve 18 on the end face.
- the flange 19 has an external guide web 22 which can be pressed into a guide groove 23 which runs in a recess (not shown) in the housing 11 and thus fixes the connector plug 12 on the housing 11.
- the described embodiment is a two-spark ignition coil
- two primary windings 24 and two secondary windings 26 are introduced into the housing 11, one of which is shown schematically in FIG. 1.
- Each of the windings 24, 26 is wound on a separate winding body, part of a primary winding body 27 being shown in FIG. 1.
- the end sections 28 of the primary winding 24 attached to it are fixed on the end face.
- the end sections 28, the beginning and end of the winding of the primary winding 24 are positioned so that they protrude the primary winding body 27 by an insertion length of about 4 mm, the end portions 28 being parallel to a longitudinal axis 29 of the primary winding 24 and perpendicular to the part of the Housing 11 are directed, which has the recess for receiving the connector 12.
- the end sections 28 of the two primary windings 24, like the pins 17 of the contacts 16 of the connector plug 12, can be connected to a connector body in the form of a carrier plate 31, or circuit board 31 for short.
- the printed circuit board 31 consists of glass fiber-reinforced, hardened epoxy resin and, in an etching process, has so-called printed circuit tracks 33 formed from a laminated copper layer 32 as lines 33, which are shown in detail in FIG.
- the conductor tracks 33 run separately from one another and, since the printed circuit board 31 consists of electrically non-conductive material, are electrically insulated from one another. They extend from a connection-side head side 34 to a foot side 36 adjacent to the end sections 28 of the primary windings 24.
- three conductor tracks 33 are required to connect the two primary windings 34, two for each of the end sections 28 of the primary windings 24, while the remaining end sections 28, when the ignition coil 10 is operating electrically at the same potential, to a common, third Conductor 33 can be connected.
- This third conductor track 33 branches off toward the foot side 36 into two separately running connection tracks 37.
- Each of the connection tracks 37 forms, with one of the other two conductor tracks 33, spatially adjacent connection locations for the two primary windings 24.
- the connecting tracks 33 or each connecting track 37 each have a bore 38 on the foot side 36.
- a bore 38 is made in the circuit boards 33 on the head side 34, as shown in FIG. While the distance between the bores 38 on the foot side 36 corresponds to that of the end sections 28 of the primary windings 24 fixed to the primary winding body 27, the distance between the bores 38 on the head side 34 is selected in accordance with the distance between the contacts 16 of the connector plug 12.
- the fastening arrangement for the connections of the ignition coil 10 according to FIG. 3 is created by first inserting the pins 17 of the contacts 16 through the holes 38 in the head side 34 of the printed circuit board 31 and then soldering each pin 17 to a conductor track 33.
- the contacts 16 are pressed in from the connection side 14 through the base 21, as a result of which the connection plug 12 and, through its connection to the printed circuit board 31, a primary plug unit 39 is formed.
- the two primary windings 24 are placed in a mounting device.
- the primary plug unit 39 is plugged onto the mounting device in such a way that the end sections 28 protrude through the bores 38.
- the end sections 28 are then soldered to the conductor tracks 33.
- This dressing is then inserted into the housing 11 so that the guide web 22 extends in the guide groove 23.
- An inexpensive and functionally safe fastening arrangement for ignition coils 10 is thus realized, which, in deviation from the exemplary embodiment described, can also be used with a multi-spark ignition coil 10 which has more than two primary windings 27.
- a circuit board 31 is preferably used for this purpose, which carries conductor tracks 33 on both sides.
- a one-sided copper-clad multilayer printed circuit board 31 would also be possible.
- the side of the printed circuit board 31 carrying the conductor tracks 33 can be opposite the connector plug 12; alternatively, this side can also be opposite to the primary windings 24 in the two cases of one-sided attachment of the conductor tracks 33.

Abstract
Description
Die Erfindung betrifft eine Befestigungsanordnung für Anschlüsse an Zündspulen von Kraftfahrzeugen nach der Gattung des Anspruchs 1.The invention relates to a fastening arrangement for connections to ignition coils of motor vehicles according to the preamble of claim 1.
Allgemein bekannt sind Befestigungsanordnungen in Zündspulengehäusen bei Mehrfunken-Zündspulen für den Anschluß der Primärwicklungen der in dem Zündspulengehäuse untergebrachten Zündspulen. Diese Befestigungsanordnungen, die auch als Stromschienen bezeichnet werden, bilden mit einem Anschlußstecker eine bauliche kunststoffumspritzte Einheit und weisen pro Zündspule zwei metallisch blanke Haken auf, an die die Endabschnitte der Primärwicklungen elektrisch kontaktiert werden. Die Stromschienen werden gebildet durch Metallstreifen mit den endseitig angeformten Haken und werden als Einlegeteile in ein Kunststoff-Spritzwerkzeug zur Herstellung des Anschlußsteckers eingebracht.Fastening arrangements in ignition coil housings in multi-spark ignition coils for connecting the primary windings of the ignition coils accommodated in the ignition coil housing are generally known. These fastening arrangements, which are also referred to as busbars, form a structural plastic-molded unit with a connector and have two bare metal hooks per ignition coil to which the end sections of the primary windings are electrically contacted. The busbars are formed by metal strips with the hooks formed on the end and are inserted as insert parts in a plastic injection mold for producing the connector.
Da die Stromschienen beim Betrieb der Zündspule unterschiedliche elektrische Potentiale führen, die Befestigungsanordnung jedoch möglichst raumsparend aufgebaut sein soll, müssen die Stromschienen eng benachbart im Spritzwerkzeug positioniert werden, ohne sich dabei zu berühren, und so fixiert werden, daß deren Ausgangsstellung durch den Spritzdruck nicht verändert wird. Diese Befestigungsanordnung ist in der Herstellung aufwendig, kostenintensiv und hat hohe Ausschußquoten.Since the busbars carry different electrical potentials during operation of the ignition coil, but the fastening arrangement should be constructed as space-saving as possible, the busbars must be positioned close to one another in the injection mold without touching each other, and fixed so that their starting position is not changed by the injection pressure becomes. This fastening arrangement is complex, expensive to produce and has high reject rates.
Die erfindungsgemäße Befestigungsanordnung mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat demgegenüber den Vorteil, daß die Verbindung der Endabschnitte der Primärspulen mit dem Anschlußstecker über eine einfach herzustellende Leiterplatte vorgenommen wird.The fastening arrangement according to the invention with the characterizing features of claim 1 has the advantage that the connection of the end sections of the primary coils with the connector is made via a circuit board that is easy to manufacture.
Diese Leiterplatte ist funktionell sicherer als die Stromschienen und besteht aus glasfaserverstärktem Epoxidharz.This circuit board is functionally safer than the conductor rails and is made of glass fiber reinforced epoxy resin.
Beim Verfüllen der fertig montierten Zündspule mit Gießharz ist das Epoxidharz der Leiterplatte mit dem Gießharz besser verbindbar als mit der kunststoffumspritzten Stromschiene. Dies führt angesichts der hohen Temperaturdifferenzen an der Zündspule beim Betrieb in einem Kraftfahrzeug zu einer verbesserten Alterungsbeständigkeit der Zündspule.When filling the fully assembled ignition coil with casting resin, the epoxy resin of the printed circuit board can be better connected to the casting resin than to the plastic-molded busbar. In view of the high temperature differences at the ignition coil when operating in a motor vehicle, this leads to improved resistance to aging of the ignition coil.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und in der Figurenbeschreibung näher erläutert.An embodiment of the invention is shown in the drawing and explained in more detail in the description of the figures.
Es zeigen Figur 1 Teile der Zündspule mit einem zweigeteilten Gehäuse. Der obere Teil des Gehäuses ist teilweise aufgeschnitten und in der Draufsicht ist der untere Teil des Gehäuses, partiell geschnitten, mit der Befestigungsanordnung dargestellt. Figur 2 zeigt die Befestigungsanordnung in einer Seitenansicht und Figur 3 die Befestigungsanordnung in einem Schnitt entlang der Linie III-III von Figur 2.FIG. 1 shows parts of the ignition coil with a two-part housing. The upper part of the housing is partially cut open and in the top view the lower part of the housing, partially cut, is shown with the fastening arrangement. Figure 2 shows the mounting arrangement in a side view and Figure 3 shows the mounting arrangement in a section along the line III-III of Figure 2.
Figur 1 zeigt einen Teil einer Zündspule 10 mit einem Gehäuse 11 und mit einem teilweise aus dem Gehäuse 11 ragenden Anschlußstecker 12. Der Anschlußstecker 12 bildet an seinem einen Ende, dem Gehäuse 11 abgewandt, eine Steckerseite 13 und an seinem anderen Ende eine Anschlußseite 14 aus.FIG. 1 shows part of an

Der Anschlußstecker 12 weist als Hauptbestandteile neben den metallischen Kontakten 16 noch eine Hülse 18 und einen Flansch 19 auf.The
Der Hülse 18 ist kastenförmig und zur Steckerseite 13 hin offen. Sie umgibt die Kontakte 16 auf der Steckerseite 13 mit Fügespiel, so daß zwischen Kontakte 16 und Bund 18 nicht dargestellte Kupplungsteile eines Gegensteckers auf die Kontakte 16 aufgeschoben werden können.The
Die Hülse 18 wird zur Anschlußseite 14 inseitig von einem Boden 21 abgeschlossen, der in den Flansch 19 übergeht, welcher die Kontur der Hülse 18 stirnseitig überragt.The
Der Flansch 19 weist einen außenliegenden Führungssteg 22 auf, der in einer Führungsnut 23, die in einer nicht dargestellten Ausnehmung des Gehäuses 11 verläuft, einpreßbar ist und so den Anschlußstecker 12 am Gehäuse 11 festlegt.The
In dem Gehäuse 11 sind, da es sich bei dem beschriebenen Ausführungsbeispiel um eine Zweifunken-Zündspule handelt, zwei Primärwicklungen 24 und zwei Sekundärwicklungen 26 eingebracht, von denen in Figur 1 je eine schematisch dargestellt ist. Jede der Wicklungen 24, 26 ist auf einem separaten Wicklungskörper aufgewickelt, wobei in Figur 1 ein Teil eines Primärwicklungskörpers 27 gezeigt ist.Since the described embodiment is a two-spark ignition coil, two
Am Primärwicklungskörper 27 sind stirnseitig zwei Endabschnitte 28 der auf ihm angebrachten Primärwicklung 24 fixiert. Die Endabschnitte 28, Wicklungsanfang und Wicklungsende der Primärwicklung 24, sind dabei so positioniert, daß sie den Primärwicklungskörper 27 um eine Einstecklänge von ca. 4 mm überragen, wobei die Endabschnitte 28 parallel zu einer Längsachse 29 der Primärwicklung 24 liegen und rechtwinklig auf den Teil des Gehäuses 11 gerichtet sind, der die Ausnehmung zur Aufnahme des Anschlußsteckers 12 aufweist.On the primary winding
Die Endabschnitte 28 der beiden Primärwicklungen 24 sind, ebenso wie die Stifte 17 der Kontakte 16 des Anschlußsteckers 12, mit einem Anschlußkörper in Form einer Trägerplatte 31, kurz Leiterplatte 31 genannt, verbindbar.The
Die Leiterplatte 31 besteht aus glasfaserverstärktem ausgehärtetem Epoxidharz und weist, in einem Ätzverfahren aus einer aufkaschierten Kupferschicht 32 herausgebildete, sogenannten - gedruckte - Leiterbahnen 33 als Leitungen 33 auf, die in der Figur 2 ausschnittsweise dargestellt sind.The printed
Die Leiterbahnen 33 verlaufen voneinander getrennt und sind, da die Leiterplatte 31 aus elektrisch nichtleitendem Material besteht, voneinander elektrisch isoliert. Sie erstrecken sich von einer anschlußseitigen Kopfseite 34 zu einer den Endabschnitten 28 der Primärwicklungen 24 benachbarten Fußseite 36.The
Im beschriebenen Ausführungsbeispiel sind zum Anschluß der beiden Primärwicklungen 34 drei Leiterbahnen 33 erforderlich und zwar zwei für je einen der Endabschnitte 28 der Primärwicklungen 24, während die verbleibenden Endabschnitte 28, beim Betrieb der Zündspule 10 elektrisch auf dem gleichen Potential liegend, an eine gemeinsame, dritte Leiterbahn 33 anschließbar sind. Diese dritte Leiterbahn 33 verzweigt sich zur Fußseite 36 hin in zwei getrennt verlaufende Anschlußbahnen 37. Jede der Anschlußbahnen 37 bildet mit je einer der anderen beiden Leiterbahnen 33 räumlich benachbarte Anschlußplätze für die beiden Primärwicklungen 24.In the exemplary embodiment described, three
Zum Zwecke des Anschlusses der Primärwicklungen 24 weisen die Anschlußbahnen 33 beziehungsweise jede Anschlußbahn 37 auf der Fußseite 36 je eine Bohrung 38 auf.For the purpose of connecting the
Zum Anschluß der Kontakte 16 des Anschlußsteckers 12 sind, in der Figur 3 dargestellt, auch auf der Kopfseite 34 in den Leiterplatten 33 je eine Bohrung 38 angebracht. Während der Abstand der Bohrungen 38 auf der Fußseite 36 dem der an dem Primärwickelkörper 27 festgelegten Endabschnitte 28 der Primärwicklungen 24 entspricht, ist der Abstand der Bohrungen 38 auf der Kopfseite 34 entsprechend dem Abstand der Kontakte 16 des Anschlußsteckers 12 zueinander gewählt.For the connection of the
Die Befestigungsanordnung für die Anschlüsse der Zündspule 10 nach Figur 3 wird erstellt, indem zunächst die Stifte 17 der Kontakte 16 durch die Bohrungen 38 der Kopfseite 34 der Leiterplatte 31 gesteckt werden und danach jeder Stift 17 mit einer Leiterbahn 33 verlötet wird.The fastening arrangement for the connections of the
Die Kontakte 16 werden von der Anschlußseite 14 her durch den Boden 21 eingepreßt, wodurch der Anschlußstecker 12 und, durch dessen Verbindung mit der Leiterplatte 31, eine Primärsteckereinheit 39 gebildet ist. Die beiden Primärwicklungen 24 werden in einer Montagevorrichtung plaziert. Dann wird die Primärsteckereinheit 39 so auf die Montagevorrichtung aufgesteckt, daß die Endabschnitte 28 durch die Bohrungen 38 ragen. Danach werden die Endabschnitte 28 mit den Leiterbahnen 33 verlötet. Dieser Verband wird anschließend in das Gehäuse 11 so eingesetzt, daß der Führungssteg 22 in der Führungsnut 23 verläuft.The
Danach schließt sich noch ein Verfüllen des Gehäuses 11 der Zündspule 10 mit Gießharz an, wodurch die Zündspule 10 fertiggestellt wird und die Leiterplatte 31 darin endgültig fixiert ist.This is followed by a filling of the
Damit ist eine kostengünstige und funktionell sichere Befestigungsanordnung für Zündspulen 10 verwirklicht, die abweichend vom beschriebenen Ausführungsbeispiel auch bei einer Mehrfunken-Zündspule 10, die mehr als zwei Primärwicklungen 27 aufweist, anwendbar ist. Dazu wird dann zur Vermeidung sich kreuzender Leiterbahnen 33 vorzugsweise eine Leiterplatte 31 verwendet, die beidseitig Leiterbahnen 33 trägt. Möglich wäre jedoch auch eine einseitig kupferkaschierte mehrlagige Leiterplatte 31. Die die Leiterbahnen 33 tragenden Seite der Leiterplatte 31 kann, wie beim beschriebenen Ausführungsbeispiel, dem Anschlußstecker 12 gegenüberliegen; alternativ kann diese Seite in den beiden Fällen der einseitigen Anbringung der Leiterbahnen 33 auch entgegengerichtet den Primärwicklungen 24 gegenüberliegen.An inexpensive and functionally safe fastening arrangement for
