Abstract
Description
Die Erfindung bezieht sich auf eine in dem Oberbegriff des Patentanspruchs 1 angegebene Anordnung, bestehend aus einem Baugruppenträger mit einer in dieser angeordneten Midplane.The The invention relates to a in the preamble of claim 1 specified arrangement, consisting of a rack with a arranged in this midplane.
Bei schirmenden Leitplatten, wie Beispielsweise einer Midplane, die eine Trennung zwischen ungeschirmten und geschirmten Räumen oder zwischen geschirmten Räumen herstellt und zugleich eine elektrische Schnittstelle beinhaltet, wird mit elektrischen Filterelementen ein Auskoppeln von elektromagnetischen Störungen erreicht. Eine derartige elektrische Schnittstelle wurde bisher durch Integration von Filterelementen auf einer Leiterplatte erreicht.at shielding guide plates, such as a midplane, the a separation between unshielded and shielded rooms or between shielded rooms produces and at the same time contains an electrical interface, becomes a coupling of electromagnetic with electrical filter elements disorders reached. Such an electrical interface has been so far achieved by integration of filter elements on a circuit board.
Der Erfindung liegt die Aufgabe zugrunde, eine weitere Anordnung von Filterelementen auf einer Leiterplatte anzugeben.Of the Invention is based on the object, a further arrangement of Specify filter elements on a circuit board.
Gemäß der Erfindung wird die gestellte Aufgabe bei der Anordnung der eingangs genannten Art durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.According to the invention The object is in the arrangement of the aforementioned Art solved by the features listed in claim 1.
Die Erfindung bringt den Vorteil mit sich, dass eine optimierte Bestückung mit Filterelementen nach einer EMV-Messung im Betrieb der Baugruppenträgeranordnung durchgeführt wird.The Invention brings with it the advantage that an optimized assembly with Filter elements after an EMC measurement during operation of the rack assembly carried out becomes.
Die Erfindung bringt den Vorteil mit sich, dass eine Auskopplung von evtl. vorhandenen Störungen mit Standardfilterelementen in vorgefertigten Steckplätzen erfolgt.The Invention brings with it the advantage that a decoupling of possibly existing disturbances with standard filter elements in prefabricated slots.
Die Erfindung bringt den Vorteil mit sich, dass das Gesamtlayout der Leiterplatten in den Baugruppenträgern bestehen bleibt.The Invention has the advantage that the overall layout of the Printed circuit boards in the racks remains.
Die Erfindung bringt den weiteren Vorteil mit sich, dass die Entstörung am Ort der Schnittstelle zwischen ungeschirmten und geschirmten Räumen oder Leitungen erfolgen kann.The Invention brings the further advantage that the suppression on Location of the interface between unshielded and shielded rooms or Lines can be made.
Die Erfindung bringt den Vorteil mit sich, dass die Filterelemente sowohl auf der ungeschirmten Seite als auch auf der geschirmten Seite einer Leiterplatte, insbesondere einer Midplane, angeordnet werden können.The Invention has the advantage that the filter elements both on the unshielded side as well as on the shielded side of a printed circuit board, especially a midplane, can be arranged.
Die Erfindung bringt den Vorteil mit sich, dass die elektrische Schnittstelle auf einer Verdrahtungsplatte beispielsweise zwischen ungeschirmten und geschirmten Bereichen eines Layouts mit gegebenenfalls geschirmten Standardbauteilen, wie z.B. Kondensatoren oder Π-Filtern nachträglich und evt. mehrfach und/oder kaskadenmäßig angeordnet werden können.The Invention has the advantage that the electrical interface on a wiring board, for example, between unshielded and shielded areas of a layout with possibly shielded Standard components, e.g. Condensers or Π-filters later and possibly several times and / or arranged in cascade can be.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen angegeben.Further advantageous embodiments of the invention are specified in the subclaims.
Weitere Besonderheiten der Erfindung werden aus der nachfolgenden näheren Erläuterung eines Ausführungsbeispiels anhand von Zeichnungen ersichtlich.Further Particular features of the invention will become apparent from the following detailed explanation an embodiment based on drawings.
Es zeigen:It demonstrate:
Die Erfindung wird Anhand einer Verdrahtungsplatte, die in diesem Ausführungsbeispiel als Midplane oder Backplane ausgebildet sein kann und eine Trennstelle zwischen forderseitig und rückseitig in der Baugruppenträgeranordnung angeordneten Baugruppen bildet, exemplarisch erläutert. Die Filterelemente können ebenso auf der Leiterplatte oder an Steckverbinderelementen variabel integriert werden. In dieser Anordnung werden Filterelemente auf der Leiterplatte, insbesondere der Backplane oder Midplane, mit mindestens einer Leiterbahnebene angeordnet. Die Leiterplatte befindet sich zwischen einem geschirmten und einem ungeschirmten oder zwischen zwei geschirmten Räumen, wobei auf der Leiterplatte Anschlussstellen AS für Filterbausteine FK, FS vorgesehen sind, die die elektromagnetische Störabstrahlung verhindern.The The invention is based on a wiring board, in this embodiment may be formed as a midplane or backplane and a separation point between the front and back in the subrack assembly arranged assemblies forms, exemplified. The filter elements can as well variably integrated on the printed circuit board or on connector elements become. In this arrangement, filter elements on the circuit board, in particular the backplane or midplane, with at least one conductor track plane arranged. The circuit board is between a shielded and an unshielded or between two shielded rooms, wherein on the PCB connection points AS for filter modules FK, FS provided are that prevent the electromagnetic interference emission.

Die Kontaktstifte der Filterkondensatoren FK kontaktieren zum einem die mit dem Signal verbundene Lage und zum anderem eine beliebige Masse bzw. Ground-Lage.The Contact pins of the filter capacitors FK contact to one the position connected with a signal and on the other any Ground or ground position.
Ähnlich ist der Aufbau von Verwendung der Filter-Drosseln. Hier muss beachtet werden, dass Drosseln in den Stromkreis seriell eingebracht werden müssen.Similar is the construction of using the filter chokes. Here must be noted be that throttles are inserted into the circuit serially have to.
