Abstract

The present invention relates to an electrical plug-in connection ( 2 ). The present invention also relates to a printed circuit board arrangement ( 1 ). An electrical plug-in connection. ( 2 ) has a plug-in connector ( 8 ) and a mating plug-in connector ( 9 ). The plug-in connector ( 8 ) contains a contact element ( 10 ), whereas the mating plug-in connector ( 9 ) contains a contact body ( 11 ) which comprises a plurality of electrically interconnected contact regions ( 14 ) which are each deformable. The contact regions ( 14 ) are arranged with respect to one another in such a way that different insertion regions ( 17 ) for inserting the contact element ( 10 ) into the contact, body ( 11 ) can be formed in the contact body ( 11 ). In each case one of the contact regions ( 14 ) is arranged between at least two of the insertion regions ( 17 ) in the contact body ( 11 ) in at least one direction which nun orthogonally to a longitudinal axis ( 16 ) of the contact element ( 10 ). The contact regions ( 14 ) each adjoining the respective insertion region ( 17 ) are deformed by the contact element ( 10 ) inserted into the respective insertion region ( 17 ) in such a way that an electrical contact and a mechanical connection can be established between the plug-in connector ( 8 ) and the mating plug-in connector ( 9 ).
