Abstract:
(EN) The invention relates to a device for shielding electronic components of high-frequency electromagnetic fields. According to the invention, a shielding device with shielding surfaces is made available, which includes at least two shielding surfaces (1, 1a) which are arranged parallel to one another, wherein capacitances are formed between the shielding surfaces (1, 1a) which have a high impedance in the kHz range and a low impedance in the MHz range, wherein the shielding surfaces (1, 1a) each have at least one slit (2, 2a, 3, 3a).
(FR) L'invention concerne un dispositif de blindage de composants électroniques contre des champs électromagnétiques haute fréquence. Le dispositif de blindage selon l'invention est pourvu d’au moins deux surfaces de blindage (1, 1a) qui sont disposées parallèlement les unes aux autres, des capacités se formant entre les surfaces de blindage (1, 1a), lesdites capacités présentant une impédance élevée dans la gamme des kHz et une faible impédance dans la gamme des mHz, les surfaces de blindage (1, 1a) présentant chacune au moins une fente (2, 2a, 3, 3a).
(DE) Die Erfindung betrifft eine Vorrichtung zur Abschirmung elektronischer Bauteile von hochfrequenten elektromagnetischen Feldern. Erfindungsgemäß wird eine Abschirmvorrichtung mit Abschirmflächen, zur Verfügung gestellt, die mindestens zwei Abschirmflächen (1, 1a) beinhaltet, die parallel zueinander angeordnet sind, wobei sich Kapazitäten zwischen den Abschirmflächen (1, 1a) bilden, die eine hohe Impedanz im kHz-Bereich und eine niedrige Impedanz im MHz-Bereich haben, wobei die Abschirmflächen (1, 1a) jeweils mindestens einen Schlitz (2, 2a, 3, 3a) aufweisen.
