Patent ID: 7883371

Claim:
An electrical connector having a mating end for receiving a complementary connector and a mounting end for being mounted to a circuit board, comprising: a housing member; a plurality of contacts attached to the housing member, the contacts comprising a plurality of first contacts having first contact portions and first tail portions, and a plurality of second contacts having second contact portions, second bending portions substantially perpendicular to the second contact portions and second tail portions formed at distal ends of the second bending portions, the first and the second contact portions being disposed at the mating end and the first and the second tail portions being disposed at the mounting end, the first and the second contact portions being located at a same side of the housing member under a condition that the first contact portions are arranged side by side along a transverse direction, and similarly, the second contact portions are arranged side by side along the transverse direction; the second contacts including a first pair of differential contacts, a second pair of differential contacts and a grounding contact disposed therebetween, the first and the second tail portions being arranged in two parallel transverse rows, wherein each of the second bending portions comprises a first width viewed from a left-to-right direction along the transverse direction, and a second width viewed from a rear-to-front direction along a longitudinal direction perpendicular to the transverse direction in condition that the second width is narrower than the first width; and wherein at the mounting end, a space between the grounding contact and the differential contact of each pair most adjacent to the grounding contact is much bigger than any internal space between the differential contacts of each the first or the second pair; a fiber optical lens is located between the first and second pair of differential contacts; wherein a tail of the grounding contact is located in a slot between the fiber optical lenses.
