The present invention relates to an appliance connector device having an A plug contact, a B plug contact and a G plug contact, an A' terminal, a B&#x2032; terminal and a G&#x2032; terminal, an electrically conducting filter jacket and a filter module, wherein the filter module has an A&#x2033; conductor, a B&#x2033; conductor and a G&#x2033; conductor, wherein the A contact is connected to the A&#x2032; terminal via the A&#x2033; conductor, wherein the B contact is connected to the B&#x2032; terminal via the B&#x2033; conductor, wherein the G contact is connected to the G&#x2032; terminal via the G&#x2033; conductor, wherein the G&#x2033; conductor of the filter module has a shielding plate extending in a cross-sectional plane of the filter jacket and wherein the filter module has capacitance elements on both sides of the shielding plate with conducting surfaces aligned parallel to the shielding plate to generate capacitances between the A&#x2033; conductor and the B&#x2033; conductor and between these conductors and the G&#x2033; conductor. With such a plug device, it is provided, in particular for improving the ground connection of the G&#x2033; conductor of the filter module, that the shielding plate is provided with a plurality of contact fingers at the edge along most of its circumference, these contact fingers being in contact with the filter jacket on the inside under elastic tension, and the filter element has a contact surface for establishing a ground connection.

Appliance connector device with integrated filter module

An electrical module for carrying electrical components is plugged into an opening in the wall of electrical apparatus, preferably from the inside. Mounting grooves on either side of the module engage corresponding edges of the wall opening in response to lateral movement which overcomes elastically yielding structure on the groove bottom of one side comprises latching structure for stably affixing the module in place in the opening so that entry from the outside of the electrical apparatus is precluded.
