Claim Text:
1. A signal transmission connector, comprising: an insulating body having a first end and a second end opposite the first end, the first end and the second end having a plurality of sidewalls arranged therebetween, the insulating body having a docking slot and a plurality of terminal slots, the sidewalls cooperatively defining the docking slot, the docking slot in air communication with the first end, the terminal slots arranged above and below the docking slot, and the insulating body having a dielectric constant substantially equal to 3.1; a plurality of first terminals disposed on the insulating body, the first terminals arranged in the terminal slots, each of the first terminals having an end extended in the docking slot of the insulating body, each of the first terminals having another end extended out of the insulating body, each of the first terminals having a width substantially equal to 0.38 mm; a plurality of second terminals disposed on the insulating body, the second terminals arranged in the terminal slots, each of the second terminals having an end extended in the docking slot of the insulating body, each of the second terminals having another end extended out of the insulating body, each of the second terminals having a width substantially equal to 0.38 mm; and a rear casing disposed at the second end of the insulating body, the rear casing disposed on the first terminal and the second terminal, the rear casing having a dielectric constant substantially equal to 3.6, and the dielectric constant of the rear casing is greater than the dielectric constant of the insulating body; wherein the terminal slots extend to the first end and the second end, each terminal slot has a front portion in air communication with the first end, the front portions have tapered cross-sections, each of the first terminals and the second terminals respectively has a contact portion arranged in each front portion; wherein each front portion having a width at upper portion and a width at lower portion thereof, and the width at upper portion is different from the width at lower portion thereof; wherein the width at upper portion of each front portion is substantially equal to a width of each contact portion, whereas the width at lower portion of each front portion is greater than the width of each contact portion; wherein the insulating body has two coupling slots arranged thereon, the rear casing has two coupling protrusions arranged thereon, and the two coupling slots are correspondingly mated to the two coupling protrusions; wherein the rear casing has a plurality of receiving slots arranged on a surface of the rear casing oriented toward the second end of the insulating body, and the first terminals are arranged in the receiving slot; wherein the width of each first terminal, the width of each second terminal, the dielectric constant of the insulating body, and the dielectric constant of the rear casing are configured so as to provide a predetermined matched impedance to maintain stability of signal transmission at the first and the second terminals.
