Description
Die Erfindung betrifft ein Funkuhr-Werk gemäß dem Oberbegriff des Anspruches 1.The invention relates to a radio clock movement according to the preamble of
Das gattungsgemäße Werk ist aus der EP 0 242 717 A2 bekannt. Innerhalb eines Uhrgehäuses aber außerhalb des Aufbaus des elektro-mechanischen Werks ist der Ferritstab mit der Spule einer magnetischen Langwellen-Antenne angeordnet und über ein flexibles zweiadriges Kabel an den fest abgestimmten Empfänger für Demodulation von binär codierten Zeittelegrammen angeschlossen. Diese Zeittelegramme liefern eine aktuelle absolute Zeitinformation, aufgrund derer die Anzeige, beispielsweise die Zeigerstellung einer elektro-mechanischen Analoganzeige, überprüft und erforderlichenfalls korrigiert wird, wie etwa in der US-PS 4,645,357 näher beschrieben.The generic work is known from EP 0 242 717 A2. The ferrite rod with the coil of a magnetic long-wave antenna is arranged inside a watch case but outside the structure of the electro-mechanical movement and connected to the permanently tuned receiver for demodulation of binary-coded time telegrams via a flexible two-wire cable. These time telegrams provide current absolute time information, on the basis of which the display, for example the position of the pointer of an electro-mechanical analog display, is checked and, if necessary, corrected, as described in more detail in US Pat. No. 4,645,357.
Bei sehr kleinen Funkuhren, wie etwa Funkarmbanduhren ist es bekannt (DE-GM 88 15 967), die magnetische Langwellen-Antenne nicht nur außerhalb des Werkes sondern sogar außerhalb des das Werk aufnehmenden Uhrengehäuses anzuordnen, dort in dem an das Uhrgehäuse angelenkten Armband. Das schränkt allerdings die Freizügigkeit bei der gestalterischen Auslegung des Armbandes ein. Diese Einschränkungen gelten entsprechend für das Uhrengehäuse, wenn dieses gemäß EP 0 382 130 A2 aus Ferrit als Antennenkern und gleichzeitig als Gehäuse zur Aufnahme des eigentlichen Werkes ausgebildet wird. Insbesondere wird der Aufbau des Armbanduhrengehäuses komplizierter, und sichere elektrische Anschlüsse zwischen der vom Gehäuse getragenen Spule und einer im Gehäuse angeordneten Schaltung sind recht aufwendig und teuer.In the case of very small radio-controlled clocks, such as radio-controlled wristwatches, it is known (DE-GM 88 15 967) to arrange the magnetic long-wave antenna not only outside the factory but even outside of the watch housing receiving the movement, there in the wristband hinged to the watch housing. However, this limits the freedom of movement in the design of the bracelet. These restrictions apply accordingly to the watch case if, according to EP 0 382 130 A2, it is made of ferrite as the antenna core and at the same time as the case for accommodating the actual work. In particular, the construction the watch case more complicated, and secure electrical connections between the coil carried by the housing and a circuit arranged in the housing are quite complex and expensive.
In Erkenntnis dieser Gegelegenheiten liegt der Erfindung die Aufgabe zugrunde, ein Werk für eine kleine, insbesondere als Armbanduhr ausgestaltbare, Funkuhr zu schaffen, bei der die gestalterische Freiheit des Gehäuses gewahrt bleibt und Anschluß-Komplikationen vermieden sind.In recognition of these opportunities, the invention has for its object to provide a work for a small, especially designed as a wristwatch, radio watch, in which the design freedom of the housing is preserved and connection complications are avoided.
Diese Aufgabe ist erfindungsgemäß im wesentlichen dadurch gelöst, daß das gattungsgemäße Werk nach dem Kennzeichnungsteil des Anspruches 1 ausgelegt ist.This object is essentially achieved in that the generic work is designed according to the characterizing part of
Nach dieser Lösung dient ein plattenförmiger Ferritantennenstab selbst als Werkplatte, Schaltungsträger und Antennenspulenkörper und stellt somit bereits ein voll funktionstüchtiges Uhrwerk dar, das im Zuge des Einbaus in ein Uhrgehäuse aus elektrisch nicht abschirmendem Material lediglich noch an eine Stromquelle (Primärbatterie bzw. elektro-chemischer oder elektro-physikalischer Speicher zur Pufferung im Falle eines Betriebes mit Solarzellen) angeschlossen zu werden braucht. Hinsichtlich der Ausgestaltung des Uhrwerks selbst sind keine konstruktiv kritischen Rücksichten mehr zu nehmen auf den Anschluß einer externen oder am Gehäuse angeordneten Antenne, weil diese nun bereits integraler Bestandteil des Werkes ist. Auch eine gesonderte Leiterplatte entfällt.According to this solution, a plate-shaped ferrite antenna rod itself serves as a work plate, circuit carrier and antenna coil former and thus already represents a fully functional clockwork that, when installed in a watch case made of electrically non-shielding material, only needs to be connected to a power source (primary battery or electrochemical or electro-physical memory for buffering in case of operation with solar cells) needs to be connected. With regard to the design of the clockwork itself, there are no longer any constructive critical considerations regarding the connection of an external antenna or antenna arranged on the housing, because this is already an integral part of the movement. There is also no separate printed circuit board.
Im Interesse hohen Antennengewindes wird das durch die Abmessungen der Werkplatte vorgegebene Volumen des Ferritkörpers nur so weit ausgehöhlt, als unbedingt zur Aufnahme höher auftragender Komponenten wie des Räderwerks mit Antriebsmotor, eines zeithaltenden Schwingquarzes und gegebenenfalls eines Antennenkreis-Abgleichkondensators erforderlich.In the interest of high antenna thread, the volume of the ferrite body specified by the dimensions of the work plate is only hollowed out to an extent that is absolutely necessary to accommodate higher-carrying components such as the gear train with drive motor, a time-keeping quartz crystal and, if necessary, an antenna circuit balancing capacitor.
Flache Komponenten wie Flüssigkristall-Displays und nichtgekapselte integrierte Schaltkreise (Dies) werden ohne Zwischenlage einer Schaltungsplatine unmittelbar auf die Werkplatte, also auf die Ferritkern-Oberfläche montiert (geklebt) und über fortschrittliche Verbindungstechniken wie beispielsweise Flip-Chip-Bonding mit den Leiterbahnen verbunden, die ebenfalls unmittelbar (erforderlichenfalls unter Zwischenlage einer Isolierschicht) in Dick- oder in Dünnschichttechnik auf die Ferritoberfläche aufgebracht sind und dort gewissermaßen ein dreidimensionales Leiterbahnen-Netzwerk ausbilden, indem sie beispielsweise zum Anschluß des Werk-Motors der Werkplatten-Oberflächen-Profilierung folgen. Die Einsenkungen zur Aufnahme dickerer Komponenten können mit der notwendigen Präzision - insbesondere im Hinblick auf die Lagerung der Zeigerwerks-Räder - in den plattenförmigen harten Ferritkörper eingeschliffen werden. Es kann aber auch eine Grobkontur im pulvermetallurgischen Spritzgußverfahren hergestellt und dieses dann durch Schleif-Nachbearbeitung auf die erforderliche Maßgenauigkeit gebracht werden, oder in die Spritzguß-Grobkontur der Werkplatte wird ein dünnes Kunststoff-Präzisionsgußteil eingelegt.Flat components such as liquid crystal displays and non-encapsulated integrated circuits (dies) are mounted (glued) directly on the work plate, i.e. on the ferrite core surface, without the interposition of a circuit board and connected to the conductor tracks using advanced connection technologies such as flip-chip bonding are also applied directly (if necessary with the interposition of an insulating layer) in thick or thin layer technology to the ferrite surface and form a three-dimensional interconnect network there, for example, by following the work plate surface profiling for connecting the factory motor. The depressions to accommodate thicker components can be ground into the plate-shaped hard ferrite body with the necessary precision - especially with regard to the mounting of the pointer wheels. However, it is also possible to produce a rough contour in the powder-metallurgical injection molding process and then bring this to the required dimensional accuracy by grinding post-processing, or a thin plastic precision casting is inserted into the rough rough contour of the work plate.
Die als Spulenkörper wirkende Einschnürung kann gegen die Zeigerwerks-Einsenkung exzentrisch versetzt an einander gegenüberliegenden Seitenrändern vorgesehen sein, was eine Feldachse parallel zur Hauptebene der Werkplatte und damit die hohe Richtungs-Empfangsempfindlichkeit eines magnetischen Dipols erbringt. Wenn diese Einschnürung stattdessen längs des Randes der Werkplatte umläuft, ergibt sich eine besonders kurze und deshalb besonders richtungsunempfindliche magnetische Antenne, weil dann die Spulenachse normal zur Hauptebene der Werkplatte orientiert ist.The constriction acting as a bobbin can be provided eccentrically offset on the side edges opposite one another against the indentation of the pointer mechanism, which provides a field axis parallel to the main plane of the workpiece plate and thus the high directional reception sensitivity of a magnetic dipole. If this constriction rotates instead along the edge of the work plate, the result is a particularly short and therefore directionally insensitive magnetic antenna, because the coil axis is then oriented normal to the main plane of the work plate.
Zusätzliche Alternativen und Weiterbildungen sowie weitere Merkmale und Vorteile der Erfindung ergeben sich aus den weiteren Ansprüchen und, auch unter Berücksichtung der Darlegungen in der Zusammenfassung, aus nachstehender Beschreibung eines in der Zeichnung unter Beschränkung auf das Wesentliche etwas abstrahiert aber angenähert maßstabsgerecht skizzierten bevorzugten Realisierungsbeispiels zur erfindungsgemäßen Lösung.

Das zeichnerisch skizzierte Werk 11 ist zum Einbau in ein kleines Uhrgehäuse bestimmt, vorzugsweise zum Einbau in das Gehäuse einer Armbanduhr. Das Werk 11 besteht im wesentlichen aus einer Werkplatte 12 zur Aufnahme des Zeigerwerks 13 und seines Motors 14 sowie wenigstens eines zeithaltenden Schaltkreises 15 mit schwingungsstabilisierendem Quarz 16. Anstelle des Zeigerwerks 13 oder zusätzlich dazu kann die Werkplatte 12 ferner als Träger einer opto-elektronischen Anzeige 31 dienen, die über einen Decoder 17 aus dem Schaltkreis 15 über einen seriellen Bus 18 betrieben werden kann, um den Aufwand für die Herstellung von Leiterbahnen 25 auf der Werkplatte 12 zu minimieren. Die am Grunde einer Getriebe-Einsenkung 19 zapfengelagerten Räder des Zeigerwerks 13 sind gegenüberliegend in einer als Lochscheibe 20 ausgebildeten Brücke gehaltert, die über der Einsenkung 19 auf der Werkplatte 12 festgelegt ist. Damit wird auch der Motor 14 in der Einsenkung 19 positioniert und seine Spule 21, die auf einem mit dem Statorblech 22 verschraubten Spulenträger 23 ruht, über Anschlußplättchen 24 (Figur 2) an die beiden Leiterbahnen 25 kontaktiert. In Fig. 2 ist zusätzlich berücksichtigt, daß ein Präzisions-Spritzgußteil 19' in die Einsenkung 19 eingelegt werden kann, um eine maßhaltige Bearbeitung des Bodens der Einsenkung 19 mit Ausbildung von Sacklöchern für Zapfenlager zu erübrigen.The
Entscheidend ist, daß die Werkplatte 12 eine, ibs. gestreckt-rechteckige, massive Platte aus mechanisch hartem aber magnetisch weichem Ferrit ist, in das nur die notwendigsten Einsenkungen 19 zur Aufnahme höher auftragender Komponenten wie des Zeigerwerks 13 mit Motor 14 oder des Quarzes 16 eingearbeitet sind, um die magnetisch wirksame Ferrit-Masse bei gegebener Fläche und Stärke der Werkplatte 12 möglichst groß zu erhalten. Dagegen wenig auftragende Komponenten wie der integrierte Schaltkreis 15 oder die optronische Anzeige 31 mit ihrem Decoder 17 sowie die Leiterbahnen 25 und gegebenenfalls eine Solarzelle 26 sind flach auf die Ferrit-Platte aufgeklebt bzw. aufkaschiert, erforderlichenfalls unter Zwischenlage einer elektrisch-isolierenden Schicht auf einer elektrisch-leitenden Oberfläche.
Diese Ferrit-Werkplatte 12 dient als Kern einer Antennenspule 27, die exzentrisch bezüglich der Platte 12 um eine als Spulenkörper wirkende Einschnürung 28 gewickelt ist. Wenn die Achse der Antennenspule 27 sich somit quer zu den Achsen des Zeigerwerks 13 und damit parallel zur Hauptebene der Werkplatte 12 erstreckt, welche z. B. Abmessungen (Länge x Breite x Dicke) der Größenordnung von 30 x 25 x 3 mm aufweist und in beliebigen Querschnittsebenen quer zur Achse der Antennenspule 27 durch Einsenkungen 19 maximal um 50 % ihrer Stärke geschwächt ist, dann entspricht eine solche Ferrit-Werkplatte 12 hinsichtlich ihres Antennengewinnes einer üblichen Ferrit-Stabantenne von etwa 30 mm Länge und 7 mm Durchmesser, mit einer solchen Antennen-Größenordnung lassen sich erfahrungsgemäß bereits gute Funkuhren-Empfangsergebnisse erzielen. Wenn dagegen (wie ebenfalls in Fig. 1 angedeutet) eine Einschnürung 28' zur Aufnahme der Windungen der Antennenspule 27 längs des Randes der Ferrit-Platte 12 verläuft, so daß die Achse der Antennenspule 27 quer zur Hauptebene der Werkplatte 12 und damit parallel zu den Achsen des Zeigerwerks 13 orientiert ist, dann ergibt sich die Wirkung einer extrem kurzen magnetischen Antenne, deren Antennengewinn zwar verringert ist, die aber gegenüber der gestreckten Geometrie der als Antennenstab wirkenden Werkplatte 12 den Vorteil besserer Rundumempfangsempfindlichkeit im Vergleich zum Dipolcharakter eines Antennen-Ferritstabes hat.It is crucial that the
