  • Electrical connector with geometrical continuity for transmitting very high frequency data signals
    Patent number: 6702617
    Abstract: A connector for cables containing at least one twisted pair for transmission of very high frequency signals. The conductors of the pair are connected in a connection block by insulation displacement contacts to contact blades, adapted to ensure contact in an interface block with the corresponding contact blades of the other connector. When connection is made, the geometry of the elements of the connection block is the same as the geometry of the elements of the interface block. This geometry is adapted so that the differential mode impedance between the conductors of each pair and the common mode impedance between the conductors and the shielding of the pair are respectively equal to the differential mode impedance between the contact blades and the common mode impedance between the contact blades and the shielding of the connector.
