ELECTRICAL PLUG-IN CONNECTOR

The invention relates to an electrical plug-in connector (1) for telecommunications and data systems technology, comprising electrically interconnected elastic high-frequency contacts (4) and core connection contacts (10). At least the high-frequency contacts (4) are arranged in a housing (2) comprising a receiving opening (3) for a counter plug-in connector, and the core connection contacts (10) are arranged in two parallel rows (8, 9). The distance between adjacent core connection contacts of a row is smaller than that between core connection contacts of different rows. The housing (2) has an upper edge (5), a lower edge (6) and two lateral edges (7), the two rows (8, 9) of core connection contacts (10) being parallel to the upper edge (5) of the housing (2).
