Die Abschirmung von elektronischen Bauteilen bzw. Geräten spielt im Zusammenhang mit der elektromagnetischen Verträglichkeit (EMV) eine wichtige Rolle. Die EMV umfasst alle ungewollten oder gewollten Funktionen und Funktionsstörungen elektrischer oder elektro nischer Betriebsmittel durch z. B. elektrische, magnetische oder elektromagnetische Felder und Vorgänge. Darin sind Beeinflussungen, die durch Ströme oder Spannungen hervorgerufen werden können, bereits eingeschlossen.The Shielding of electronic components or devices plays in the context of electromagnetic compatibility (EMC) an important role. The EMC includes all unwanted or wanted functions and malfunctions electrical or electro nic resources by z. B. electrical, magnetic or electromagnetic fields and processes. Are in it Influences caused by currents or voltages can already be included.
Wesentlich für die Sicherstellung der elektromagnetisch verträglichen Funktion der elektrischen Betriebsmittel ist deren sachgerechter Aufbau und Gestaltung, wobei der Nachweis und die Bestätigung der Störunempflindlichkeit und hinreichend geringer Störaussendung durch EMV-Richtlinien und EMV-Normen geregelt sind.Essential for ensuring the electromagnetically acceptable Function of electrical equipment is more appropriate Construction and design, whereby the proof and the confirmation of the Störunempflindlichkeit and sufficiently low noise emission regulated by EMC guidelines and EMC standards.
Das übliche Störkopplungsmodell geht von den Begriffen Störquelle, Kopplungspfad und Störsenke aus. Das Störungen erzeugende Betriebsmittel wird als Störquelle, das beeinflussende Betriebsmittel wird als Störsenke bezeichnet. Damit es zu einer Beeinflussung der Senke durch die Quelle kommen kann, muss die Störung zur Senke gelangen, um dort als Störgröße wirken zu können. Den Weg zwischen Quelle und Senke nennt man Kopplung oder Kopplungspfad. Das Kriterium für die Güte einer Signalübertragung ist in der EMV der Störabstand.The usual Jamming coupling model is based on the terms jamming source, Coupling path and Störseke off. The disturbances generating resources is as a source of interference, the influencing Operating equipment is referred to as a disturbance sink. So that must be able to influence the sink by the source get the disturbance to the sink to there as a disturbance to be able to act. The path between source and sink calls one coupling or coupling path. The criterion for the Quality of a signal transmission is in the EMC of Signal to noise ratio.
In einer bevorzugten Variante des erfindungsgemäßen Gegenstands ist das Material der Außenschicht des Beutels ausgewählt aus der Gruppe bestehend aus Kunststoffen, wie z. B.

Rundfunk empfänger oder andere Betriebsmittel in der Störumgebung nicht unzulässig beeinflusst werden.By These materials ensure that the emissions are so small that z. B. broadcast receivers or others Equipment in the interference environment is not inadmissible to be influenced.
Es wird zwischen natürlichen und technischen Störquellen und Störsenken unterschieden. Als Beispiele für eine natürliche Störquelle gilt ein Blitz, natürliche Senken können Lebewesen sein. Typische technische Störquellen sind z. B. Frequenzumrichter, typische technische Störsenken sind z. B. Funkempfangsgeräte.It becomes between natural and technical sources of interference and Disturbance distinguished.
