Shielding spring contact, plug-in connector comprising a shielding spring contact, and plug-in connector system comprising a shielding spring contact
A shielding spring contact includes a flat base portion having a top side and a cutout, and a shielding portion having a wall connected to the flat base portion and encircling the cutout. The wall has an outer side, an inner side, an upper side, and a lower side. The lower side of the wall is arranged on the top side of the flat base portion with the lower side of the wall laterally surrounding the cutout. The top side of the flat base portion bears against a bottom side of an assembly housing portion of a first plug-in connector and the shielding portion projects through a first passage opening in the assembly housing portion. The shielding portion projects through a second passage opening in a shielding housing wall and into a shielding housing of a second plug-in connector, bearing against the shielding housing wall.
