in a contact connecting of preferably a number of shielded conductor pairs to a board in particular of a plug for high - speed data connections , the board is formed of multiple layers and contains a conductor path tier and a ground tier . a ground contact zone of the ground tier projects , in a tongue - like manner , towards the connected conductor pairs . in the region of the ground contact zone , the individual conductor pairs are pressed in contact against the corresponding pair shielding thereof . to this end , in particular a clamping element is provided that is also used to achieve the shield contacting .
