Abstract

For the transmission of high-frequency signals >2.5 GHz or 5 Gbps by means of a separable plug connection, the invention proposes a symmetrically shaped electric contact (1, 1′) that features a contact body (4) with the contact side (3) with U-shaped spring legs (13), as well as a connection end (5).Contact domes (15) that are directed toward one another and feature contact zones (16) that are narrower than the material thickness of the spring legs (13) are integrally formed onto both spring legs (13).When joining the two electric contacts (1, 1′) that are mated while they are turned relative to one another by 90 degrees in the mating direction, the contact domes (15) or their contact zones (16) of one electric contact (1, 1′) engage into the contact body (4) of the other electric contact (1, 1′) in a paired fashion such that electric signals travel distances with identical transit times on one leg and on the other leg and so-called stub effects, i.e., transit time differences that cause a partial obliteration of certain signal portions, due to different distances in a contact wiring are prevented.
