" Entstördrossel für elektrische Geräte ""Suppression choke for electrical devices"
Die Erfindung bezieht sich auf eine Drossel zum Entstören von elektrischen Geräten wie Steuer- oder Regelgeräten, insbesondere elektrischen Geräten kleiner Abmessungen.The invention relates to a choke for suppressing interference in electrical devices such as control or regulating devices, especially small electrical devices.
Aufgabe der Erfindung ist es, eine Entstördrossel zu schaffen, die bei verhältnismässig kleinen Abmessungen sowohlThe object of the invention is to create an interference suppression choke that has both relatively small dimensions

Gemäss der Erfindung ist eine Entstördrossel für elektrische Geräte als Ringdrossel mit einem Kern aus unterschiedlich breiten Spiralbändern aus ungeglühten, legierten Weicheisen ausgebildet.**According to the invention, an interference suppression choke for electrical devices is designed as a ring choke with a core made of spiral strips of different widths made of non-annealed, alloyed soft iron. **
Bei einer vorteilhaften Ausführungsform kann ein Spiralband und zwar das breitere Band aus einer Weicheisen - Silizium Legierung mit einem Anteil von 2 bis 5%t vorzugsweise 3% Silizium bestehen, während das andere schmalere Spiralband aus einer Weicheisen - Nickel - Legierung hergestellt ist, die 3o bis ko% Ni, vorzugsweise 35 - 3755 Ni enthältIn an advantageous embodiment, a spiral band, namely the wider band, can be made of a soft iron - silicon alloy with a proportion of 2 to 5% t, preferably 3% silicon, while the other narrower spiral band is made of a soft iron - nickel alloy, the 3o contains up to ko% Ni, preferably 35-3755 Ni
Eine solche als Ringkerndrossel ausgebildete Entstördrossel nimmt dadurch wenig Raum ein, da in ihrem mittleren Ringraum das die Störungen hervorrufene Element angeordnet werden kann.Such an interference suppression choke, designed as a toroidal core choke, takes up little space because it is in its central annulus the element causing the disturbances can be arranged.

Je nach der Wahl des Bandwerkstoffes und nach der Breite der nebeneinanderliegenden und übereinanderliegenden, beispielsweise mittels Klebstoff miteinander verbundenen Spiralbänder können die gewünschten Frequenzbereiche, in denen Störungen zu erwarten sind, vorgesehen werden.Depending on the choice of tape material and the width of the adjacent and superimposed, for example Spiral bands connected to one another by means of adhesive can be used to create the desired frequency ranges, in which disturbances are to be expected are provided.
