ABSTRACT:
A connector plug has an electrical radio frequency suppression filter comprising a metallic filter housing partially slipped onto the plug, the filter having electrical filter components, particularly inductances and capacitances, disposed within the filter housing, embedded in a casting compound, partially connected to the device plug leads at the power supply side and partially connected to the leads facing the device to be energized, whereby the device-side leads, particularly tabs, extend out of the open end face of the filter housing facing away from the plug and a broad surface protective conductor is connected to the filter housing in an electrically conductive manner. The protective conductor is preferably designed as a cross-shaped protective conductor within the filter housing and whose one ends are connected to terminals of Y-capacitors. The cross-shaped protective conductor and the electrical filter components are thereby located at opposite sides of an insulating lamina.
