Abstract
Description
In aktuellen Kommunikationssystemen ist die Abschirmung von elektronischen Baugruppen oder Subsystemen gegen Störstrahlungen von außen - z.B. Blitz, UKW- und Radarsender mit Frequenzen bis in den GHz-Bereich und deren Harmonischen - und gegen Störstrahlungen von internen Störquellen mit großem technischen und wirtschaftlichen Aufwand verbunden. Beispielsweise können Taktgeneratoren im 10 MHz-Bereich mit kurzen Signalanstiegszeiten Harmonische bis in den GHz-Bereich erzeugen und zu Fehlfunktionen benachbarter Systeme führen. Die Abschirmung von Geräteschnittstellen ist im Gegensatz zu Gehäusen und Kabeln nur mit erheblichen Aufwand möglich. In der von der Firma CONEC herausgegebenen Druckschrift "CONEC Filter-Steckverbinder, Ihr Partner für EMV Lösungen", 1997 ist beispielsweise im Abschnitt "Filter-Steckverbinder - Eine EMV-gerechte Lösung" der Einsatz von Filtersteckverbindungen beschrieben, um z.B. das Ein- und Austreten von Störstrahlungen aus Steckeröffnungen eines abgeschirmten Gehäuses und die daraus resultierende Wirkung als Schlitzantenne zu verhindern. Desweiteren ist der Einsatz von Adapter-Steckern - zwischen Steck- und Gegensteckvorrichtung eingefügt - zur Filterung von Störsignalen aus mit dem Stecker verbundenen Signalleitungen bekannt. Adapter-Stecker weisen jedoch einen erhöhten Platzbedarf auf und sind nur für eine beschränkte Anzahl von Steckverbinder-Typen erhältlich, z.B. für D-Substecker. Weiterhin sind Steckverbinder mit integrierten Filterfunktionen bekannt, bei denen jedoch eine nachträgliche Änderung bzw. Anpassung der Filtereigenschaften nicht möglich ist.In current communication systems, the shielding of electronic assemblies or subsystems against interference radiation from outside - e.g. Flash, FM and radar transmitters with frequencies up to the GHz range and their harmonics - and against interference radiation from internal sources of interference with large technical and economic effort. For example can clock generators in the 10 MHz range with short Signal rise times Harmonics up to the GHz range generate and lead to malfunctions of neighboring systems. The shielding of device interfaces is in contrast to Housings and cables only possible with considerable effort. In the publication "CONEC Filter connectors, your partner for EMC solutions ", 1997 is, for example, in the section "Filter Connectors - One EMC-compliant solution "the use of filter plug connections described e.g. the entry and exit of interference radiation from plug openings of a shielded housing and the resulting effect as a slot antenna prevent. Furthermore, the use of adapter plugs - inserted between plug and mating device - for Filtering of interference signals from the connector Signal lines known. However, adapter plugs have one increased space requirements and are only limited Number of connector types available, e.g. for D-sub connector. There are also connectors with integrated filter functions known, but with a subsequent It is not possible to change or adapt the filter properties is.
