Abstract: An electrical circuit board plug contact device includes an electrical circuit board contact element and an electrical plug contact element formed separately from the electrical circuit board contact element. The electrical plug contact element is laterally offset with respect to the electrical circuit board contact element and an electrically conductive connection is provided between the electrical circuit board contact element and the electrical plug contact element.

Abstract: 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.

Abstract: An assembly includes at least three layers of sheet metal lying directly on top of one another and joined in a stack of sheet metal. The layers of sheet metal are each joined in pairs by a clinching joint. At least one layer of sheet metal arranged between one of the pairs of layers of sheet metal joined by the clinching joint and an outer side of the stack each have an access opening aligned with the clinching joint.

Abstract: A touch-proof contact arrangement includes a pin contact having a pair of sides and a free end and a contact protection formed of an electrically insulating material and covering the sides and the free end of the pin contact. The contact protection has a pair of legs and a connecting section connecting the legs. The sides of the pin contact are received in a pair of lateral recesses of the legs of the contact protection.
