Abstract:
A connector to connect cables of twisted pair for the transmission of very high-frequency differential data signals, in which the conductors of a twisted pair are connected in a connection block by insulation displacement contacts to contact blades, said contact blades including an auto-latching mechanism adapted to ensure contact in an interface block with the corresponding contact blades of another connector, wherein:each of said contact blades has a constant thickness (T), and has an initial width (W) in a rectilinear part and a narrower second width (Wc) in a portion where contact is made with a corresponding portion of a contact blade of another connector such that the common mode impedance is equal to: Zc=60&varepsilon;&it;â€ƒ&it;r&it;Ln&af;(1.9&it;B0.8&it;W+T)where Ln stands for neperian logarithm, and B=2H+T, where H is the distance between the middle point of the base of the blade and the wall of a cavity, and is the same in the rectilinear part and in the portion where the contact is made when Wc=Wâˆ’1.25T.
