High-speed communication connector capable of improving transmission quality and of controlling transmission characteristics

A high-speed communication connector, which is of a board-to-board type and is capable of improving communication quality and of controlling communication characteristics, comprising:

• a finger body formed at one side of a PCB, the finger body including a plurality of anode terminals formed on one side thereof at predetermined intervals, a plurality of cathode terminals formed on another side thereof at predetermined intervals so as to be symmetrical with the plurality of anode terminals, and shield bodies made of conductive material and formed inside and between the plurality of anode terminals and inside and between the plurality of cathode terminals at predetermined intervals;
• and
• a receptacle body having a groove formed in a side surface thereof so as to be engaged with the one surface and the another surface of the finger body, the receptacle body including a plurality of anode pins and a plurality of cathode pins, which are respectively brought into contact with the plurality of anode terminals and the plurality of cathode terminals for electrical connection, shield plates made of conductive material, the shield plates being interposed between differential lines, each of which is composed of one of the anode pins and a corresponding one of the cathode pins, at predetermined intervals so as to distinguish the differential lines from each other, and pieces of dielectric material having a low permittivity and disposed in spaces defined between the anode pins, the cathode pins, and the shield plates, other than the groove, so as to form a body of the receptacle body, the pieces of dielectric material being selectively controlled in kind and amount so as to control impedances in consideration of frequency bands corresponding to the differential lines, which are isolated from each other by means of the shield plates.
