Cable connector with system for high-speed signal transmission

A cable connector comprising:

• an insulative housing having a mating face, a mounting face opposite to the mating face, a cavity defined in the mounting face, and a plurality of passageways through the mating face and in communication with the cavity;
• a plurality of data terminals being received in the insulative housing;
• a plurality of high-speed signal terminals each having a contact portion at a front end thereof and extending through a corresponding passageway of the insulative housing, a solder portion at a rear end thereof for terminating a center conductor of a coaxial cable, and a fitting portion between the contact portion and the solder portion;
• a grounding plate having a front blade portion, a rear jointing portion, and a pair of teeth laterally projecting from two opposite side edges thereof;
• an insulative spacer having a front face, a rear face opposite to the front face, an elongate slot extending through both faces for receiving the grounding plate, a pair of grooves recessed from the front face and in communication with the slot for receiving the teeth of the grounding plate, and a plurality of passageways on opposite sides of the slot for receiving the fitting portions of the signal terminals, the insulative spacer together with the grounding plate being securely insertable into the cavity to firmly clamp the signal terminals between the insulative spacer and the insulative housing;
• and
• a ferrule for clamping the metallic braid of the coaxial cable to the grounding plate;
• wherein the fitting portion comprises a widened portion adjacent to the contact portion, and a position portion between the widened portion and the solder portion, the position portion being fitted in a corresponding passageway of the insulative spacer, and the widened portion being clamped between the insulative housing and the insulative spacer.
