The invention relates to a network connector assembly for vehicles. The network communicates at data rates of 100 Mbit/s and/or 1 Gbit/s. The connector assembly includes a header having at least two pins forming a pin pair. The pins extend in a mating direction. The connector assembly also includes an electrically conductive shielding member shielding the pin pair on at least two sides. The shielding member has a front face that is oriented substantially normal to the mating direction. The connector assembly further includes a header shroud, wherein the header shroud is provided with a shielding cavity for receiving the shielding member. The front face of the shielding member is at least partly covered by the header shroud.
