Description

Die Erfindung betrifft eine Spulenanordnung mit einem Wickelkörper, auf welchem die Spulenwicklung angebracht ist sowie ein Verfahren zur Kontaktierung dieser auf einem Trägerkörper.The invention relates to a coil arrangement with a winding body on which the coil winding is attached and a method for contacting it on a carrier body.

Spulen werden in einer Vielzahl von Meßwerken zur Erzeugung eines Magnetfeldes genutzt. Dazu ist es notwendig, daß der Spulenwicklung kontinuierliche Stromsignale oder Stromimpulse zugeführt werden. Zu diesem Zweck werden die Wicklungsenden der Spule mit stromführenden elektrischen Zuleitungen verbunden. In den meisten Fällen wird ein Wicklungsende mit der elektrischen Zuleitung verlötet oder verklebt.Coils are used in a large number of measuring mechanisms to generate a magnetic field. For this purpose, it is necessary for the coil winding to be supplied with continuous current signals or current pulses. For this purpose, the winding ends of the coil are connected to current-carrying electrical leads. In most cases, one end of the winding is soldered or glued to the electrical lead.

Bei heutigen Meßwerken wird die Spulenwicklung auf einen Wickelkörper aufgewickelt. Die Drahtenden werden an separaten Kontaktstiften verlötet. Dieser Kontaktstift wiederum wird mit den elektrischen Zuleitungen verlötet. Für jede Spulenanordnung sind somit mehrere Arbeitsgänge notwendig.In today's measuring mechanisms, the coil winding is wound on a winding body. The wire ends are soldered to separate contact pins. This contact pin is in turn soldered to the electrical leads. This means that several operations are required for each coil arrangement.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Spulenanordnung anzugeben, welche einfach herstellbar ist sowie eine einfache und zuverlässige elektrische Kontaktierung erlaubt.The invention is therefore based on the object of specifying a coil arrangement which is simple to produce and allows simple and reliable electrical contacting.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß am Wickelkörper zwei Kontaktfüße angeordnet sind und an jedem Kontaktfuß jeweils ein Ende der Spulenwicklung befestigt ist.According to the invention the object is achieved in that two contact feet are arranged on the winding body and one end of the coil winding is attached to each contact foot.

Der Vorteil der Erfindung besteht darin, daß durch den Wegfall von zusätzlichen Kontaktelementen ein kostengünstiger Fertigungsablauf möglich ist. Die Wicklung des Spulenkörpers ist in einem einzigen Arbeitsgang ohne zusätzlichen Aufwand möglich, in dem zuerst der erste Kontaktfuß, danach der Wickelkörper und zuletzt der zweite Kontaktfuß umwickelt wird.The advantage of the invention is that the elimination of additional contact elements enables an inexpensive manufacturing process. The winding of the coil body is possible in a single operation without additional effort, in which the first contact foot is wrapped first, then the winding body and finally the second contact foot.

Durch den Wegfall der Kontaktstifte wird eine Kostenreduzierung und eine Erhöhung der Zuverlässigkeit erreicht.By eliminating the contact pins, costs are reduced and reliability is increased.

In einer Weiterbildung ist mindestens ein Kontaktfuß gabelförmig gestaltet. Der gabelförmige Kontaktfuß weist dabei eine dem Spulenkörper abgewandte Ausnehmung auf.In one development, at least one contact foot is fork-shaped. The fork-shaped contact foot has a recess facing away from the coil former.

Insbesondere die Ausnehmung ermöglicht die Ansammlung von Kontaktpaste beim Kontaktierungsvorgang, was aufgrund der breiten Kontaktfläche zu einer sicheren und haltbaren Kontaktierung führt.In particular, the recess enables contact paste to accumulate during the contacting process, which leads to reliable and durable contacting due to the wide contact area.

Vorteilhafterweise weist der Kontaktfuß eine Aussparung oder Erhebung zur Aufnahme des Wicklungsendes auf. Diese Aussparung ist zwischen Wickelkörper und der Ausnehmung angeordnet. Unterhalb des gabelförmigen Kontaktfusses ist eine Führung für die Wicklung des jeweiligen Wicklungsendes vorgesehen.The contact foot advantageously has a cutout or elevation for receiving the winding end. This recess is arranged between the winding body and the recess. A guide for the winding of the respective winding end is provided below the fork-shaped contact foot.

In einer Ausführung ist jedes Wicklungsende mit mindestens einer Windung um einen Kontaktfuß geschlungen. Eine mehrlagige Umschlingung jedes Kontaktfusses führt zu einer zuverlässigen Befestigung des jeweiligen Wicklungsendes am Kontaktfuß.In one embodiment, each winding end is wrapped around a contact foot with at least one turn. A multilayer wrap around each contact foot leads to a reliable fastening of the respective winding end to the contact foot.

Ein solcher geschickt gestalteter Wickelkörper mit zwei angespritzten Kontaktfüssen trägt die Spulenwicklung und sorgt für eine sichere Fixierung der Drahtenden an den Kontaktfüssen. Die Drahtenden selbst werden mit den elektrischen Zuleitungen direkt verbunden.Such a cleverly designed winding body with two molded contact feet supports the coil winding and ensures that the wire ends are securely fixed to the contact feet. The wire ends themselves are connected directly to the electrical leads.

Zur Kontaktierung auf einer ebenen Leiterplatte ist es sinnvoll, daß der Kontaktfuß parallel oder senkrecht zur Spulenwicklung an einem Ende des Wickelkörpers angeordnet ist.For contacting on a flat circuit board, it is useful that the contact foot is arranged parallel or perpendicular to the coil winding at one end of the winding body.

Dabei werden die Abstände der beiden Kontaktfüße voneinander sinnvollerweise so gewählt, daß sie dem Abstand der Leitbahnen der Leiterplatte entsprechen.The distances between the two contact feet from each other are usefully chosen so that they correspond to the distance of the interconnects of the circuit board.

Die erfindungsgemäße Spulenanordnung ermöglicht eine einfache Kontaktierung auf einem mit elektrischen Zuleitungen versehenen Trägerkörper, in dem die am Kontaktfuß befestigten Wicklungen eines Wicklungsendes der Spulenwicklung dicht genug an der Zuleitung angeordnet sind und mittels eines geeigneten Verbindungsverfahrens, z. B. mit Hilfe einer elektrisch leitfähigen Kontaktpaste mit elektrischen Zuleitungen kontaktiert werden.The coil arrangement according to the invention enables simple contacting on a carrier body provided with electrical supply lines, in which the windings of a winding end of the coil winding fastened to the contact base are arranged close enough to the supply line and by means of a suitable connection method, e.g. B. with the aid of an electrically conductive contact paste with electrical leads.

Ein mechanischer Kontakt zwischen Wicklungsende der Spulenwicklung und der Zuleitung ist wünschenswert aber nicht zwingend notwendig.A mechanical contact between the winding end of the coil winding and the feed line is desirable but not absolutely necessary.

Ein kleiner Spalt zwischen Wicklung und Zuleitung kann durch Löten mit Kapillarwirkung bzw. Schweißen mit Anpreßkraft leicht überwunden werden.A small gap between the winding and the supply line can be easily overcome by soldering with capillary action or welding with contact pressure.

Die Kontaktierung kann dabei mittels Verfahren wie z. B. Thermokompressionsschweißen, Löten mit einer Lötpaste, Aufschmelzen mittels Infrarotstrahlung, Laser oder Thermode oder Leitkleben erfolgen.The contacting can be done using methods such. B. thermocompression welding, soldering with a solder paste, melting using infrared radiation, laser or thermode or conductive adhesive.

Ist der Trägerkörper eine Leiterplatte, bietet sich ein automatisches Reflowlöt- oder Aufschmelzverfahren zur Kontaktierung an. Die Leiterplatte ist dabei vorzugsweise eine flexible Leiterfolie oder ein Verbundleitersystem.If the carrier body is a printed circuit board, an automatic reflow soldering or melting process for contacting is recommended. The circuit board is preferably a flexible conductor foil or a composite conductor system.

Die Erfindung ermöglicht zahlreiche Ausführungsformen. Eine davon soll anhand der in der Zeichnung dargestellten Figur näher erläutert werden.The invention enables numerous embodiments. One of these will be explained in more detail with reference to the figure shown in the drawing.

Sie zeigt die Kontaktierung der erfindungsgemäßen Spulenanordnung auf einer Leiterplatte 27, wie es in Meßwerken für Anzeigesysteme in Kraftfahrzeugen genutzt wird.It shows the contacting of the coil arrangement according to the invention on a printed circuit board 27, as is used in measuring mechanisms for display systems in motor vehicles.

Die Spulenanordnung besteht aus einem Wickelkörper 24 mit einer Spulenwicklung 22. Dieser Wickelkörper 24 weist zwei elektrisch isolierende Kontaktfüße 25a und 25b auf, die in einer Ebene an einem Ende des Wickelkörpers 24 parallel zur Wicklung 22 befestigt sind. Die Kontaktfüße 25a und 25b weisen dabei einen identischen Aufbau auf. Sie sind so gabelförmig gestaltet, daß sie in der zum Wickelkörper 24 entgegengesetzten Richtung eine Ausnehmung 34a, 34b haben, die zur Leitbahn der Leiterplatte 27 offen ist.The coil arrangement consists of a winding body 24 with a coil winding 22. This winding body 24 has two electrically insulating contact feet 25a and 25b, which are attached in one plane to one end of the winding body 24 parallel to the winding 22. The contact feet 25a and 25b have an identical structure. They are so fork-shaped that they have a recess 34a, 34b in the opposite direction to the winding body 24, which is open to the interconnect of the circuit board 27.

Unterhalb des gabelförmigen Kontaktfusses ist eine Führung in Form einer Nut für die um den Kontaktfuß geführten Windungen 28a, 30a des Wicklungsendes 28, 30 vorgesehen. In Richtung der Erregerwicklung zwischen Wickelkörper 24 und der Ausnehmung 34a, 34b weisen die Kontaktfüße 25a und 25b jeweils eine Aussparung 32a bzw. 32b zur Fixierung der Windungen 28a und 30a am jeweiligen Kontaktfuß auf.Below the fork-shaped contact foot, a guide in the form of a groove is provided for the turns 28a, 30a of the winding end 28, 30 guided around the contact foot. In the direction of the excitation winding between the winding body 24 and the recess 34a, 34b, the contact feet 25a and 25b each have a cutout 32a and 32b for fixing the turns 28a and 30a to the respective contact foot.

Herstellungsmäßig wird ein erstes Ende 28 der Spulenwicklung 22 mehrfach um den ersten Kontaktfuß 25a gewickelt, so daß die Windungen 28a nach der Montage auf die Leiterplatte die Leitbahn 26 berühren.In terms of manufacture, a first end 28 of the coil winding 22 is wound several times around the first contact foot 25a, so that the turns 28a touch the interconnect 26 after assembly on the printed circuit board.

Nach Umwicklung des ersten Kontaktfusses 25a wird der Wickelkörper 24 mit der Spulenwicklung 22 versehen. Danach wird der zweite Kontaktfuß 25b in der gleichen Art und Weise wie der erste Kontaktfuß 25a mit dem zweiten Spulenende 30 umwickelt.After winding the first contact foot 25a, the winding body 24 is provided with the coil winding 22. Thereafter, the second contact foot 25b is wrapped with the second coil end 30 in the same manner as the first contact foot 25a.

Zur Kontaktierung werden die Kontaktfüße 25a und 25b auf der Leiterplatte 27 aufgesetzt und sind elektrisch mit der Leitbahn 26, 26a der Leiterplatte 27 verbunden. Die Wicklungen 28a berührt dabei die Leitbahn 26 und die Wicklungen 30a die Leitbahn 26a.For contacting, the contact feet 25a and 25b are placed on the circuit board 27 and are electrically connected to the conductor track 26, 26a of the circuit board 27. The windings 28a contact the interconnect 26 and the windings 30a the interconnect 26a.

Die Kontaktierung der Windungen 28a und 30a der beiden Spulenenden 28 bzw. 30 erfolgt über eine Lötverbindung 31.The turns 28a and 30a of the two coil ends 28 and 30 are contacted via a soldered connection 31.

Die gabelförmige Ausführung ermöglicht die Ansammlung von Kontaktpaste, im vorliegenden Fall Lötpaste und gewährleistet somit eine zuverlässige Kontaktierung der Leitbahnen mit den Wicklungsenden.The fork-shaped design allows contact paste to accumulate, in the present case solder paste and thus ensures reliable contacting of the interconnects with the winding ends.

Neben einem automatischen Lötvorgang kann die Kontaktierung aber auch durch Leitkleben erfolgen.In addition to an automatic soldering process, the contact can also be made by conductive gluing.
