 Körper durch einen Teil 11 geschlossen. Ein solcher mit der Wicklung versehener Sekundärteil ist in Fig. 5 dargestellt. Der nach Aufschieben des   Deckelkörpers   11 auf den Wickelkörper 7 verbleibende Spalt 12 wird verlötet oder durch eine Falznaht verbunden, so dass dadurch alle Käfigteile miteinander galvanisch verbunden sind, mit Ausnahme der Überlappungsstellen. Dadurch wird ein allseitig geschlossenes Gehäuse erhalten, welches die darin befindlichen Wicklungen sowohl gegen hochfrequente Störfelder als auch gegen die sieh längs der Netzleitung fortpflanzenden Störspannungen vollkommen schützt. 



   Anstatt wie bei dem dargestellten Beispiel die Sekundärwicklung kann auch die Netzwieklung in den Käfig eingebaut werden, während die übrigen Apparatewicklungen ausserhalb des Abschirmkäfigs angebracht sind. Ferner kann der   Abschirmkäfig   auch so ausgebildet sein, dass sieh darin mehrere durch je einen galvanisch mit dem Käfig verbundenen Schirm voneinander getrennte Wicklungen befinden. Um eine kapazitive Störbeeinflussung der innerhalb des Käfigs befindliehen Wicklung mit den übrigen Transformatorwicklungen zu verhindern, ist der Käfig mit dem gemeinsamen Bezugspunkt des Empfängers galvanisch zu verbinden und gegebenenfalls zu erden. 



   Anstatt den Käfig aus Blech, z. B. Kupferblech, aufzubauen, kann er auch als Drahtgeflecht in der dargestellten und beschriebenen Weise hergestellt sein. 



   PATENT-ANSPRÜCHE :
1. Drosseleinrichtung zur Abhaltung von leitungsgeriehteten hochfrequenten Störspannungen, welche über das Speisenetz zu einem Hoehfrequenzempfangsgerät gelangen, dadurch gekennzeichnet, dass zwischen der die Störfrequenzen enthaltenden Netzspeiseleitung und der   Stromversorgungsein-     riehtung   des   Hochfrequenzempfangsgerätes   ein Transformator eingefügt ist, von dessen Wicklungen wenigstens eine innerhalb eines allseitig geschlossenen Absehirmkäfigs eingebaut ist.

 Body closed by part 11. Such a secondary part provided with the winding is shown in FIG. The gap 12 remaining after the cover body 11 has been pushed onto the winding body 7 is soldered or connected by a folded seam so that all cage parts are thereby galvanically connected to one another, with the exception of the overlap points. As a result, a housing that is closed on all sides is obtained, which completely protects the windings located therein against high-frequency interference fields as well as against the interference voltages propagating along the power line.



   Instead of the secondary winding, as in the example shown, the Netzwklung can also be built into the cage, while the remaining apparatus windings are attached outside the shielding cage. Furthermore, the shielding cage can also be designed in such a way that it contains several windings separated from one another by a shield each galvanically connected to the cage. To prevent capacitive interference between the winding located inside the cage and the other transformer windings, the cage must be galvanically connected to the common reference point of the receiver and, if necessary, grounded.



   Instead of the cage made of sheet metal, e.g. B. copper sheet to build, it can also be made as a wire mesh in the manner shown and described.



   PATENT CLAIMS:
1. Throttle device for preventing line-directed high-frequency interference voltages, which reach a high-frequency receiving device via the supply network, characterized in that a transformer is inserted between the power supply line containing the interference frequencies and the power supply device of the high-frequency receiving device, of which at least one winding is closed on all sides Absehirmcage is installed.

2. Drosseleinrichtung nach Anspruch 1, dadurch gekennzeichnet, dass wenigstens eine Käfigwand eine Überlappung aufweist, deren Enden durch einen Isolator elektrisch voneinander derart getrennt sind, dass dadurch der Käfig keine Kurzschlusswicklung für den Transformator bildet. EMI2.1 2. Throttle device according to claim 1, characterized in that at least one cage wall has an overlap, the ends of which are electrically separated from one another by an insulator in such a way that the cage does not form a short-circuit winding for the transformer.
