Patent ID: 8083546

Claim:
An electric connector suitable for being mounted on a circuit board, the circuit board having a first surface and a second surface opposite to the first surface, and the circuit board comprising a first circuit disposed on the first surface and a second circuit disposed on the second surface, the electric connector comprising: a metallic case; an insulating base connected with the metallic case; a plurality of first leads disposed on the insulating base and soldered to the first surface, wherein the first leads comprises: a pair of first differential signal leads; a pair of second differential signal leads; and a first ground lead located between the pair of first differential signal leads and the pair of second differential signal leads, wherein the pair of first differential signal leads and the pair of second differential signal leads of the first leads are soldered to the first circuit; and a plurality of second leads disposed on the insulating base and soldered to the second surface, wherein the second leads comprises: a power lead; a second ground lead; and a pair of third differential signal leads located between the power lead and the second ground lead, wherein the pair of third differential signal leads of the second leads are soldered to the second circuit.
