Description

STAND DER TECHNIKSTATE OF THE ART

Die Erfindung betrifft eine Ferritantenne, insbesondere eine Ferritantenne für Kraftfahrzeuge.The invention relates to a ferrite antenna, in particular a ferrite antenna for motor vehicles.

Ferritantennen sind aus dem Stand der Technik hinlänglich bekannt. Ferritantennen werden in Kraftfahrzeugen beispielsweise zur drahtlosen Kommunikation mit Codegebern benötigt. Eine derartige Ferritantenne ist beispielsweise aus der Druckschrift mit der Veröffentlichungsnummer WO 02/095873 A2 benannt. Die Ferritantenne weist eine Wicklung auf, die um einen Kern aus Ferritmaterial herum angeordnet ist. Dem die Wicklung tragenden ersten Kern, der fest in einem Haltemittel angeordnet ist, ist ein zweiter Kern aus Ferritmaterial zugeordnet, der koaxial zum ersten Kern in axialer Richtung bewegbar im gleichen Haltemittel angeordnet ist. Einander zugewandten Stirnflächen der beiden Kerne können einen vorgegebenen, durch Bewegung des zweiten Kerns in axialer Richtung zu Abgleichzwecken veränderbaren Abstand voneinander aufweisen, wobei der zweite Kern nach dem Abgleich an dem Haltemittel festgelegt werden kann.Ferrite antennas are well known in the art. Ferrite antennas are needed in motor vehicles, for example, for wireless communication with encoders. Such a ferrite antenna is for example from the publication with the publication number WO 02/095873 A2 named. The ferrite antenna has a winding disposed around a core of ferrite material. The winding-carrying first core, which is fixedly arranged in a holding means, a second core of ferrite material is associated, which is arranged coaxially with the first core in the axial direction movable in the same holding means. Mutually facing end faces of the two cores can have a predetermined distance which can be varied from one another by movement of the second core in the axial direction for adjustment purposes, wherein the second core can be fixed to the retaining means after the adjustment.

Die in der Druckschrift offenbarte Ferritantenne hat sich in der Vergangenheit als geeignet erwiesen. Lediglich die Abstimmung der Antenne und das anschließende Festlegen des zweiten Ferritkerns in seiner abgestimmten Position, bereitet einige Mühe. Die Position, in welcher der zweite Ferritkern festgelegt wird, unterscheidet sich von Ferritantenne zu Ferritantenne aufgrund der mechanischen Toleranzen der Ferritkerne. Während der Montage des zweiten Ferritkerns muss also eine Veränderung des Abstands zwischen dem ersten Ferritkern und dem zweiten Ferritkern möglich sein. Der zweite Ferritkern ist daher frei auf dem Haltemittel verschiebbar. Dieses führt bei der Montage des Ferritkerns der aus der genannten Druckschrift bekannten Ferritantenne dazu, dass nach der Abstimmung der Antenne und vor dem Festlegen des zweiten Ferritkerns ein unbeabsichtigtes Verschieben des zweiten Ferritkerns möglich ist. Ist es zufällig und unbeabsichtigt zu einer Verschiebung des zweiten Ferritkerns nach dem Abstimmen gekommen, verändert sich das Frequenzverhalten der Antenne und die Ferritantenne kann nur eingeschränkt brauchbar oder gar unbrauchbar sein.The ferrite antenna disclosed in the document has proved suitable in the past. Only the tuning of the antenna and the subsequent fixing of the second ferrite core in its tuned position, makes some effort. The position in which the second ferrite core is fixed differs from ferrite antenna to ferrite antenna due to the mechanical tolerances of the ferrite cores. During assembly of the second ferrite core, therefore, a change in the distance between the first ferrite core and the second ferrite core must be possible. The second Ferrite core is therefore freely displaceable on the holding means. This leads in the assembly of the ferrite core known from the cited ferrite antenna that after tuning the antenna and before setting the second ferrite core unintentional displacement of the second ferrite core is possible. If it has happened accidentally and unintentionally to a shift of the second ferrite core after tuning, the frequency response of the antenna changes and the ferrite antenna can be useful only limited or even unusable.

Hier setzt die vorliegende Erfindung an.This is where the present invention begins.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Ferritantenne vorzuschlagen, bei der der zweite Ferritkern, nach dem Abstimmen der Ferritantenne und vor dem Festlegen des zweiten Kerns so angebracht ist, dass der zweite Ferritkern möglichst nicht oder nur erschwert verschiebbar ist.The present invention has for its object to provide a ferrite antenna, in which the second ferrite core, after tuning the ferrite antenna and before fixing the second core is mounted so that the second ferrite core is not possible or only difficult displaced.

VORTEILE DER ERFINDUNGADVANTAGES OF THE INVENTION

Diese Aufgabe wird durch eine erfindungsgemäße Ferritantenne nach Anspruch 1 gelöst. Eine solche Ferritantenne weist an dem Haltemittel vorgesehene federnde Halteelemente auf, mit dem zumindest der zweite Ferritkern vor dem dauerhaften Festlegen fixierbar ist.This object is achieved by a ferrite antenna according to claim 1 according to the invention. Such a ferrite antenna has resilient holding elements provided on the holding means, with which at least the second ferrite core can be fixed prior to the permanent fixing.

Während der erste Ferritkern weiterhin unmittelbar durch Kleben an dem Haltemittel angebracht werden kann, ist es bei einer erfindungsgemäßen Ferritantenne möglich, dass der zweite Ferritkern in einer durch die Halteelemente zumindest in einer ersten Richtung festgelegten Position an dem Haltemittel festgehalten ist. Nach der Abstimmung der Antenne, wozu der zweite Ferritkern in eine zweite Richtung, senkrecht zur ersten Richtung verschiebbar ist, kann dann der zweite Ferritkern festgeklebt werden. Lediglich die Position bezüglich der zweiten Richtung wird durch das Verschieben des zweiten Ferritkerns beim Abstimmen eingestellt.Furthermore, while the first ferrite core can be attached directly to the holding means by gluing, it is possible for a ferrite antenna according to the invention that the second ferrite core is retained on the holding means in a position determined by the holding elements at least in a first direction. After tuning the antenna, for which the second ferrite core is displaceable in a second direction, perpendicular to the first direction, then the second ferrite core be stuck. Only the position with respect to the second direction is adjusted by the displacement of the second ferrite core during tuning.

Vorzugsweise ist der erste Ferritkern von einer Spule umwickelt.Preferably, the first ferrite core is wound by a coil.

Die federnden Halteelemente sind vorzugsweise einstückig mit dem übrigen Haltemittel verbunden. Geeigneter Weise kann das Haltemittel ein Kunststoffspritzgussteil sein.The resilient retaining elements are preferably integrally connected to the rest of the retaining means. Suitably, the holding means may be a plastic injection molded part.

BESCHREIBUNG DER AUSFÜHRUNGSBEISPIELEDESCRIPTION OF THE EMBODIMENTS

Die erfindungsgemäße Ferritantenne gemäß Fig. 1 weist einen ersten Ferritkern 1 auf, der mit einer Spule 5 bewickelt ist. Daneben weist die Ferritantenne einen zweiten Ferritkern 2 auf, der nicht bewickelt ist. Sowohl der erste Ferritkern 1 als auch der zweite Ferritkern 2 sind an einem Haltemittel 3 angebracht.The ferrite antenna according to the invention according to FIG. 1 has a first ferrite core 1 which is wound with a coil 5. In addition, the ferrite antenna has a second ferrite core 2 which is not wound. Both the first ferrite core 1 and the second ferrite core 2 are attached to a holding means 3.

Das Haltemittel 3 besteht im Wesentlichen aus einer länglichen Grundplatte, wobei an den Längsrändern an der Oberseite Stege 6 angebracht sind, die sich über die gesamte Länge des Haltemittels 3 erstrecken. Auf der Oberseite des Haltemittels 3 ist dann in einem ersten Bereich der erste bewickelte Ferritkern 1 aufgeklebt. Anschlussdrähte 5a, 5b der Spule 5 sind zu dem nahe liegenden schmalseitigen Ende des Haltemittels 3 geführt und über Anschlusspins 7, die in die Grundplatte des Haltemittels 3 eingepresst sind, an andere elektrische Einrichtungen anschließbar. An dem dem Anschlusspin 7 gegenüberliegenden Ende des ersten Ferritkerns schließt sich ein zweiter Bereich des Haltemittels 3 an, in welchem der zweite Ferritkern 2 angebracht ist. Auch dieser zweite Ferritkern 2 ist bei einer vollständig fertiggestellten Ferritantenne an dem Haltemittel 3 angeklebt.The holding means 3 consists essentially of an elongated base plate, wherein on the longitudinal edges of the upper webs 6 are attached, which extend over the entire length of the holding means 3. On the upper side of the holding means 3, the first wound ferrite core 1 is then glued in a first region. Connecting wires 5a, 5b of the coil 5 are guided to the near narrow end of the holding means 3 and connected via connecting pins 7 which are pressed into the base plate of the holding means 3, to other electrical devices. At the opposite end of the terminal pin 7 ferrite core, a second region of the holding means 3 connects, in which the second ferrite core 2 is mounted. Also, this second ferrite core 2 is adhered to the holding means 3 in a completely finished ferrite antenna.

Zur Abstimmung der Ferritantenne müssen die beiden Ferritkerne 1, 2 in eine bestimmte Lage zueinander gebracht werden. Nur dann ist die Ferritantenne zum Senden beziehungsweise Empfangen von Signalen in einem bestimmten Frequenzband geeignet. Da die Ferritkerne 1,2 nur mit großen mechanischen Toleranzen hergestellt werden können, ist es notwendig, dass die Ferritkerne 1,2 bei der Montage abgestimmt auf die Sendebeziehungsweise Empfangsfrequenz an dem Haltemittel 3 befestigt werden.To tune the ferrite antenna, the two ferrite cores 1, 2 must be brought into a certain position to each other. Only then is the ferrite antenna suitable for transmitting or receiving signals in a specific frequency band. Since the ferrite cores 1, 2 can only be produced with large mechanical tolerances, it is necessary for the ferrite cores 1, 2 to be fastened to the holding means 3 in tune with the transmission and reception frequencies during assembly.

Für die Montage der Ferritkerne 1, 2 wird zunächst der erste Ferritkern 1 in dem vorgesehenen Bereich festgeklebt. Anschließend wird der zweite Ferritkern 2 an dem Haltemittel 3 angebracht, ohne ihn jedoch mit dem Haltemittel 3 zu verkleben. Zum Fixieren des zweiten Ferritkerns 2 sind dabei federnde Halteelemente 4 vorgesehen. Diese federnde Halteelemente 4, die auch als Federelemente 4 bezeichnet werden, sind an den Stegen 6 des Haltemittels 4 angebracht.For the assembly of the ferrite cores 1, 2, the first ferrite core 1 is first glued in the intended area. Subsequently, the second ferrite core 2 is attached to the holding means 3 without, however, bonding it to the holding means 3. For fixing the second ferrite core 2 while resilient retaining elements 4 are provided. These resilient retaining elements 4, which are also referred to as spring elements 4, are attached to the webs 6 of the holding means 4.

Unterhalb der Federelemente 4 sind aus fertigungstechnischen Gründen Ausnehmungen 7 vorgesehen. Die Federelemente 4 ragen schräg in den Innenraum zwischen den beiden Stegen 6 hinein. Sie sind so ausgelegt, dass der zweite Ferritkern 2 zwischen den federnden Halteelementen 4 eingesetzt werden kann, wobei die federnden Halteelemente 4 dann unter Spannung an dem zweiten Ferritkern 2 anliegen. Die federnden Halteelemente 4 gewährleisten, dass der zweite Ferritkern 2 in einer ersten Richtung E mittig zwischen den Stegen 6 des Haltemittels 3 angeordnet ist. Gleichzeitig ist der zweite Ferritkern 2 jedoch in eine zweite Richtung Z senkrecht zur ersten Richtung E verschiebbar. Dadurch kann der Abstand zwischen dem ersten Ferritkern 1 und dem zweiten Ferritkern 2 durch ein Verschieben des zweiten Ferritkerns 2 eingestellt werden, um die Ferritantenne abzustimmen. Ist die Ferritantenne unter Zuhilfenahme anderer elektrischer Geräte abgestimmt worden, wird der zweite Ferritkern 2 in der beim Abstimmungsvorgang eingestellten Position festgeklebt.Below the spring elements 4 recesses 7 are provided for manufacturing reasons. The spring elements 4 project obliquely into the interior space between the two webs 6. They are designed so that the second ferrite core 2 can be inserted between the resilient retaining elements 4, wherein the resilient retaining elements 4 then rest under tension on the second ferrite core 2. The resilient retaining elements 4 ensure that the second ferrite core 2 is arranged centrally in a first direction E between the webs 6 of the retaining means 3. At the same time, however, the second ferrite core 2 is displaceable in a second direction Z perpendicular to the first direction E. Thereby, the distance between the first ferrite core 1 and the second ferrite core 2 can be adjusted by shifting the second ferrite core 2 to tune the ferrite antenna. If the ferrite antenna has been tuned with the aid of other electrical equipment, the second ferrite core 2 is glued in the position set during the voting process.
