- the individual foils can be glued or laminated together, for example.
- the production by means of foils, which can be processed, for example, from the roll, enables particularly cost-effective production with high throughput.
- a preferred field of application of the switching matrix is the use as a signal-independent, remotely controllable distributor in communication and data technology.
Abstract
Description
Die Erfindung betrifft ein Koppelfeld zur Schaltung elektrischer Signalleitungen.The invention relates to a switching matrix for switching electrical signal lines.
Koppelfelder werden vorzugsweise in der Kommunikations- und Datentechnik eingesetzt, wenn eine große Anzahl von Leitungen geschaltet werden muß.Coupling fields are preferably used in communication and data technology used when a large number of lines must be switched.
Im allgemeinen werden elektronische Koppelfelder benutzt, die platzsparend als integrierte Schaltungen ausgerührt sind. Diese haben jedoch den Nachteil, nur spezifische Signalarten schalten zu können. Außerdem sind die elektronischen Koppelfelder empfindlich gegenüber elektromagnetischer Störstrahlung (EMV) und großen Temperaturschwankungen. Koppelfelder, die nicht an eine spezifische Signalart gebunden sind, beruhen auf elektrodynamischen, thermischen oder elektrostatischen Eigenschaften. Diese Koppelfelder sind sehr komplex ausgebildet, was sehr hohe Fertigungskosten zur Folge hat. Ähnliches gilt für mikromechanische Koppelfelder.In general, electronic switching fields are used, which save space as integrated circuits are developed. However, these have the disadvantage of only to be able to switch specific signal types. In addition, the electronic Coupling fields sensitive to electromagnetic interference (EMC) and large temperature fluctuations. Switching fields that are not connected to a specific signal type are based on electrodynamic, thermal or electrostatic Characteristics. These switching fields are very complex, which is very high Has manufacturing costs. The same applies to micromechanical coupling fields.
Eine weitere Art nicht signalgebundener Koppelfelder sind die bekannten elektromechanischen Koppelfelder. Diese bestehen aus einzelnen Relais, die durch entsprechende Verdrahtung mittels Draht oder Leiterplatten zu Koppelfeldern zusammengefügt werden. Diese Art der Ausführung der Koppelfelder wird insbesondere bei einer großen Anzahl von Koppelpunkten problematisch, da diese dann in verschiedenen Ebenen angeordnet werden müssen. Hierzu müssen große Mengen von Verbindungskabeln und verschiedenen Ansteuermodulen verwendet werden. Außerdem muß bei nicht selbsthaltenden Relais fortlaufend Strom durch die Spule fließen, um den Kontakt geschlossen zu halten. Dies führt zu einer unerwünscht großen Leistungsaufnahme, insbesondere da in vielen Anwendungen die einzelnen Koppelpunkte nur sehr selten geschaltet werden.Another type of switching fields that are not signal-bound are the known ones electromechanical coupling fields. These consist of individual relays that pass through Corresponding wiring using wire or printed circuit boards to coupling fields be put together. This type of execution of the switching matrix is particularly problematic with a large number of crosspoints, since these then in must be arranged at different levels. This requires large amounts of Connection cables and various control modules can be used. Moreover In the case of non-latching relays, current must flow continuously through the coil in order to Keep contact closed. This leads to an undesirably large Power consumption, especially since in many applications the individual Crosspoints are only switched very rarely.
Aus der WO 92/22919 ist ein derartiger dreidimensionaler galvanischer Schalter bekannt, bei dem mittels dreier Positionierachsen kugelförmige Verbindungsmittel bewegt werden. Die kugelförmigen Verbindungsmittel sind abwechselnd leitend bzw. isolierend ausgeführt, so daß der entsprechende Koppelpunkt entweder durchgeschaltet oder geöffnet wird. Dieses bekannte Koppelfeld erlaubt eine kompakte, selbsthaltende Bauweise der Koppelfelder. Nachteilig bei dieser Ausführung ist die aufwendige und kostspielige Mechanik.Such a three-dimensional galvanic switch is known from WO 92/22919 is known in which by means of three positioning axes spherical connecting means be moved. The spherical connecting means are alternately conductive or Insulated so that the corresponding crosspoint is either switched through or is opened. This well-known switching matrix allows a compact, self-holding Construction of the coupling fields. The disadvantage of this design is the complex and costly mechanics.
Ein Koppelfeld mit den Merkmalen des Oberbegriffs von Anspruch 1 ist aus DE-A-2 260 002 bekannt.A switching matrix with the features of the preamble of
Der Erfindung liegt von daher das Problem zugrunde, ein robustes, signalartunabhängiges, Koppelfeld zu schaffen, das in kostengünstiger und kompakter Bauweise herzustellen ist.The invention is therefore based on the problem of a robust, to create signal-independent, switching matrix that is more cost-effective and compact Construction is to be produced.
Die Lösung des Problems ergibt sich aus dem Patentanspruch 1 Vorteilhafte
Weiterbildungen der Erfindung sind in den Unteransprüchen erfaßt.The solution to the problem results from
Durch die Zuordnung eines Permanentmagneten zu der einen Kontaktfläche und der Zuordnung einer Spule mit ferromagnetischem Werkstoff zu der gegenüberliegenden Kontaktfläche eines jeden Koppelpunktes ergibt sich eine besonders einfache und robuste Ausführung des Koppelfeldes. Durch die selektive Erregung der Spule eines Koppelpunktes wird der zugeordnete ferromagnetische Werkstoff magnetisiert. Bei geeigneter Polung der Erregung kommt es zu einer magnetischen Anziehungskraft zwischen Permanentmagnet und ferromagnetischem Werkstoff und somit der sich gegenüberliegenden Kontaktflächen. Der Koppelpunkt wird also geschlossen. Dieser Zustand verbleibt auch nach Abschalten der Erregung der Spule. Durch Umpolung der Erregung kann der Koppelpunkt wieder geöffnet werden. Durch die Ausführung des Koppelfeldes mittels Folien ist eine besonders kompakte Bauweise der Koppelfelder möglich. Außerdem erlaubt die Ausführung mittels Folien eine kostengünstige Fertigung der Koppelfelder, da die entsprechend vorverarbeiteten Folien von der Rolle weiterverarbeitbar sind und so ein besonders hoher Durchsatz erreichbar ist.By assigning a permanent magnet to the one contact surface and the Assignment of a coil with ferromagnetic material to the opposite one Contact area of each coupling point results in a particularly simple and robust design of the switching matrix. By the selective excitation of the coil one The assigned ferromagnetic material is magnetized. at Appropriate polarity of the excitation leads to a magnetic attraction between permanent magnet and ferromagnetic material and thus the itself opposite contact surfaces. The crosspoint is therefore closed. This The state remains even after the excitation of the coil is switched off. By reversing the polarity The coupling point can be opened again. The design of the switching matrix using foils makes it particularly compact Design of the coupling fields possible. In addition, the execution by means of foils an inexpensive production of the coupling fields, since the correspondingly pre-processed Sheets of rolls can be processed further and thus a particularly high throughput is achievable.
Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispieles näher erläutert. Die einzige Figur zeigt einen Querschnitt durch einen Koppelpunkt des Koppelfeldes.The invention is explained in more detail below on the basis of a preferred exemplary embodiment explained. The single figure shows a cross section through a coupling point of the Switching matrix.
Das Koppelfeld besteht aus einer Vielzahl bevorzugt matrixförmig angeordneter
Koppelpunkte 1. Übersichtlichkeitshalber ist in der Figur 1 nur ein Koppelpunkt 1
im Querschnitt dargestellt. Als Basis des Koppelfeldes dient vorzugsweise eine
mechanisch flexible Folie 2 . Auf die mechanisch flexible Folie 2 wird eine
mechanisch stabile Folie 3 aufgebracht. Die beiden Folien 2, 3 können miteinander
verklebt werden oder abschließend mit den anderen Folien laminiert werden. Die
mechanisch stabile Folie 3 ist im Bereich der Koppelpunkte 1 geöffnet. Dies kann
z.B. durch Ausstanzen oder andere in der Folientechnik bekannte Verfahren geschehen.
Auf die mechanisch stabile Folie 3 wird eine mechanisch flexible Folie 4
aufgebracht, auf deren Unterseite im Bereich der Koppelpunkte 1 Permanentmagnete
5 und an deren Oberseite Kontaktflächen 6 befestigt sind. Die Befestigung der
Permanentmagnete 5 und der Kontaktflächen 6 erfolgt vorzugsweise durch
Verkleben mit der mechanisch flexiblen Folie 4 . Die Abmessungen des
Permanentmagneten 5 sind etwas kleiner als die durch die Öffnung der mechanisch
stabilen Folie 3 entstandenen Hohlräume. Auf die mechanisch flexible Folie 4 ist
eine mechanisch stabile Folie 7 aufgebracht, die im Bereich der Koppelpunkte 1
geöffnet ist. Die mechanisch stabile Folie 7 ist prinzipiell genauso aufgebaut wie die
mechanisch stabile Folie 3 . Auf der mechanisch stabilen Folie 7 ist eine mechanisch
flexible Folie 8 aufgebracht, an deren Unterseite im Bereich der Koppelpunkte 1
Kontaktflächen 9 und an deren Oberseite ein ferromagnetischer Werkstoff 10
befestigt sind. Die Befestigung der Kontaktflächen 9 und des ferromagnetischen
Werkstoffes 10 erfolgt vorzugsweise durch Verklebung. Die Kontaktflächen 6, 9
sind deckungsgleich zueinander angeordnet, wobei es prinzipiell auch möglich ist, daß
an stelle einer mehrere Kontaktflächen 6, 9 verwendet werden. Auf die mechanisch
flexible Folie 8 ist eine mechanisch stabile Folie 11 aufgebracht, die im Bereich der
Koppelpunkte 1 geöffnet sind. Die mechanisch stabile Folie 11 ist prinzipiell
genauso aufgebaut wie die zuvor beschriebenen mechanisch stabilen Folien 3, 7 . Die
Höhenabmessung des ferromagnetischen Werkstoffes 10 kann kleiner bzw. gleich der
Höhenabmessung der mechanisch stabilen Folie 11 sein. Auf die mechanisch stabile
Folie 11 ist eine vorzugsweise mechanisch stabile Folie 12 aufgebracht. In die Folie
12 sind im Bereich der Koppelpunkte 1 Spulen 13 eingebettet oder eingeätzt. Die
elektrischen Zuführungen 14 der Spulen 13 sind auf der Folie 12 vorzugsweise
matrixförmig zu den Rändern des Koppelfeldes hin angeordnet.
Nachfolgend wird die Funktion des Koppelfeldes erläutert.
Wird selektiv bei entsprechender Polung die Spule 13 eines Koppelpunktes 1 erregt, so
baut sich ein Magnetfeld auf, das den ferromagnetischen Werkstoff 10 magnetisiert.
Dadurch kommt es zu einer magnetischen Anziehungskraft zwischen dem
Permanentmagnet und dem ferromagnetischen Werkstoff 10 . Durch die Kraft werden
die mechanisch flexiblen Folien 4, 8 so weit durchgebogen, daß sich die
Kontaktflächen 6, 9 berühren und den Koppelpunkt durchschalten. Wird nun die
Erregung der Spule 13 unterbrochen, so verbleibt der ferromagnetische Werkstoff 10
in seinem magnetisierten Zustand, und der Koppelpunkt 1 bleibt durchgeschaltet. Soll
der Kontakt wieder getrennt werden, erregt man die Spule 13 mit umgekehrter
Polung. Die elektrischen Signalleitungen, die über die Kontaktflächen 6, 9
miteinander verbunden bzw. getrennt werden, werden vorzugsweise als Leiterbahnen
auf den mechanisch flexiblen Folien 4, 8 zu den Rändern des Koppelfeldes
herausgeführt. Die Abstände zwischen den einzelnen Koppelpunkten 1 müssen
ausreichend groß gewählt werden, daß zum einen eine magnetische Beeinflussung
vermieden wird und zum anderen die mechanisch flexiblen Folien 4, 8 im Bereich
eines Koppelpunktes 1 ausreichend eingespannt sind, so daß durch die Durchbiegung
der Folien 4, 8 an einem Koppelpunkt 1 die umliegenden Koppelpunkte 1 nicht
beeinflußt werden. Prinzipiell ist es auch möglich, den Permanentmagneten 5 als
Kontaktfläche 6 zu verwenden oder aber den Permanentmagneten 5 direkt unter der
Kontaktfläche 6 anzuordnen. Dadurch kann die Kompaktheit des Koppelfeldes
zusätzlich erhöht werden. Wie schon zuvor angedeutet, können die einzelnen Folien
miteinander z.B. verklebt oder laminiert werden. Durch die Herstellung mittels Folien,
die z.B. von der Rolle verarbeitet werden können, ist eine besonders kostengünstige
Produktion mit hohem Durchsatz möglich. Ein bevorzugtes Anwendungsfeld des
Koppelfeldes ist die Verwendung als signalunabhängiger, fernsteuerbarer Verteiler in
der Kommunikations- und Datentechnik. The switching matrix consists of a large number of
