Definitions
- the invention relates to a damping device for one Operating current superimposed on the operating current higher-frequency interference currents, at least consisting of one inductance through which the operating current flows.
- the object of the present invention is now a damping device for electronic consumers taking advantage the special properties of nanocrystalline and / or amorphous materials with a relative permeability of over 20,000 to take advantage of a damping of Interference currents in electronic components in a wide range Generate frequency range without special Components are required.
- This object is achieved in that as Inductance on from amorphous or nanocrystalline Material with a relative permeability of more than 20,000 existing toroid on a pin within the Housing a connector is applied.
- the housing 1 consists of two merged parts 2 and 3 shown.
- Pins 4 are fastened in a holding body 6 via insulation material 5 and have a distance of 3 mm, for example from each other.
- the space thus formed is invented exploited to 7 cores, which are made of amorphous or nanocrystalline Tape exist to accommodate.
- the material these cores have a relative permeability of over 20,000, giving one to the pin 4 they surround inductive resistance, the high-frequency interference current prevents and thus the electromagnetic compatibility the device connected to the connector has been significantly improved, without additional space for damping devices is available.
- the effect of the damping device results in principle even if only a pen is provided with such a core is. However, an improvement can be achieved if several or all the pins of a plug from such a ring core are surrounded. However, if every pen has a Toroid is to be provided, it is necessary to Select the outer diameter of the toroid smaller than that free space between two pins 4 is.
