A double-shielded high-speed docking connector is disclosed in this invention. The connector includes a shell, a positioning seat and a row of frame assemblies. The frame assembly includes an insulating body, two columns of signal terminals supported by the insulating body and arranged to be multiple differential pairs, a first shielding member mounted on one side of the insulating body, and a second shielding member mounted on the other side of the insulating body and connected with the first shielding member. The double-shielded high-speed docking connector of the present invention can not only reduce crosstalk between the signal terminals of adjacent differential pairs, but also effectively reduce signal interference of adjacent frame assemblies by disposing two shielding members on each frame assembly.
