Abstract

An EMC filter plug-in arrangement with an EMC filter to avoid or reduce electrical and/or electromagnetic interference caused by an electronic component, in particular an inverter of a refrigerant compressor. The EMC filter plug-in arrangement has an EMC filter, a plug-in housing formed for receiving the EMC filter and having electrical conductor contacts formed on the outside which are in electrical contact with the EMC filter, and a plug-in receptacle formed for arrangement with an electronic component into which the plug-in housing can be plugged in to provide electrical contact between the EMC filter and the electronic component.

First claim

The invention claimed is:

a plug-in housing formed for receiving the EMC filter and having first electrical conductor contacts formed on an outside which are in electrical contact with the EMC filter, the plug-in housing having a first end with a first planar end face, a second end opposite the first end of the plug-in housing, and a voltage terminal in electrical contact with the EMC filter and extending outwardly from a second planar end face disposed at the second end of the plug-in housing, wherein the second planar end face is parallel with the first planar end face, and wherein the first electrical conductor contacts are formed on the first planar end face; and
a plug-in receptacle formed for arrangement with an electronic component, the plug-in receptacle having a recessed first portion for receiving the electronic component and an extended second portion with an aperture formed through the recessed portion and the extended portion, wherein the first end of the plug-in housing is received through the aperture to engage the electronic component, wherein the first electrical conductor contacts of the plug-in housing are in electrical contact with third electrical conductor contacts formed on the electronic component.

2. The EMC filter plug-in arrangement according to claim 1 , wherein the first electrical conductor contacts formed on the outside are flexible or are formed in the form of spring elements, and wherein the first electrical conductor contacts are in the form of metal strips bent in a z-shape.

3. The EMC filter plug-in arrangement according to claim 1 , wherein the voltage terminal, by means of which the EMC filter is in electrical contact via at least two of the first electrical conductor contacts formed on the outside.

4. The EMC filter plug-in arrangement according to claim 1 , wherein the plug-in housing has openings and/or holes in which second electrical conductor contacts in electrical contact with the EMC filter are formed.

5. The EMC filter plug-in arrangement according to claim 1 , wherein the plug-in housing has a stop flange with openings formed therein, the flange formed about an external surface of the plug-in housing intermediate the first end of the plug-in housing and the second end of the plug-in housing, wherein sleeve-shaped second electrical conductor contacts are formed in the openings, which are in electrical contact with the EMC filter.

6. The EMC filter plug-in arrangement according to claim 1 , wherein the plug-in housing is attachable to the plug-in receptacle by means of electrically conductive attachment means.

7. The EMC filter plug-in arrangement according to claim 1 , wherein the plug-in housing is formed from a casting compound, the EMC filter being enclosed by the casting compound.

8. The EMC filter plug-in arrangement according to claim 1 , wherein the plug-in receptacle is integrated in a housing for the electronic component.

9. The EMC filter plug-in arrangement according to claim 1 , wherein the plug-in receptacle is formed at the electronic component in such a way that a plug-in direction of the plug-in housing is aligned orthogonally to a circuit board of the electronic component.

10. The EMC filter plug-in arrangement according to claim 1 , wherein an outer shape of the plug-in housing and an inner shape of the plug-in receptacle correspond with each other according to a Poka-Yoke principle.

11. The EMC filter plug-in arrangement according to claim 1 , wherein the EMC filter has at least one current-compensated choke and at least one interference-suppression capacitor.

12. An EMC filter plug-in arrangement, comprising: an EMC filter to avoid or reduce electrical and/or electromagnetic interference caused by an electronic component having electronic component conductor contacts, the EMC filter having a circuit board with bridge conductors, first interference-suppression capacitors in electrical contact with at least one of the bridge conductors, at least one second interference-suppression capacitor extending between the bridge conductors, and a current compensated choke; a plug-in housing formed for receiving the EMC filter and having first electrical conductor contacts formed on an outside which are in direct electrical contact with the bridge conductors of the EMC filter, the plug-in housing having a first end and a second end opposing the first end, the first electrical conductor contacts extending from the first end of the plug-in housing and a voltage terminal in electrical contact with the bridge conductors extending from the second end of the plug-in housing; and
a plug-in receptacle formed for arrangement with an electronic component having an aperture formed therethrough, into which the plug-in housing can be plugged in to provide direct electrical contact between the EMC filter and the electronic component conductor contacts, wherein the plug-in housing has openings and/or holes in which second electrical conductor contacts in electrical contact with the EMC filter are formed, wherein the interference-suppression capacitors are in electrical communication with the second electrical conductor contacts and disposed intermediate the bridge conductors and the second electrical conductor contacts with respect to a flow of electric current through the circuit board, and wherein the first end of the plug-in housing is received through the aperture.

13. An EMC filter plug-in arrangement, comprising:
an EMC filter to avoid or reduce electrical and/or electromagnetic interference caused by an electronic component;
a plug-in housing formed for receiving the EMC filter and having first electrical conductor contacts and a voltage terminal, the first electrical conductor contacts formed on an outside of a first end of the plug-in housing which are in direct electrical contact with the EMC filter and the electronic component and the voltage terminal extending from a second end of the plug-in housing opposite the first end with respect to a lengthwise direction of the plug-in housing, and
a plug-in receptacle formed for arrangement with an electronic component, into which the plug-in housing can be plugged in to provide electrical contact between the EMC filter and the electronic component, wherein the plug-in receptacle has an aperture formed therethrough for receiving the first end of the plug-in housing, wherein the plug-in housing has a stop flange formed intermediate the first end of the plug-in housing and the second end of the plug-in housing, the stop flange has openings with sleeve-shaped second electrical conductor contacts being formed in the openings, which are in electrical contact with the EMC filter, wherein the stop flange prevents the second end of the plug-in receptacle from extending into the aperture of the plug-in receptacle, the second electrical conductor contacts configured to electrically contact the electronic component via electrically conductive couplings.
