ELECTRICAL CONNECTOR

摘要

An electrical connector (10) comprises a housing (12), and a plurality of contact modules (50) in said housing (12), each said contact module (50) comprising a mating edge and a mounting edge (56), each said mating and mounting edge (56) having a row of contacts (82, 86) including signal contacts and ground contacts. Each mating edge contact (82) is electrically connected to a corresponding mounting edge contact (86) by signal conductors (106a, 106b, 206a, 206b) and ground conductors (104, 204) extending along a predetermined path within said contact module (50) to form a lead frame (100, 200) in each contact module (50), said ground conductors (104, 204) and signal conductors (106a, 106b, 206a, 206b) being arranged in an adjacent relationship to provide electrical shielding. The signal conductors (106a, 106b, 206a, 206b) and ground conductors (104, 204) of several contact modules (50) are arranged, when seen in a cross-sectional view through the lead frames, in an array having outer and inner layers. So as to provide an electrical connector with reduced crosstalk and uniform electrical properties of its conductors, at least a portion of the signal conductors (106a, 106b) and ground conductors (204a, 204b) in the outer layers has a width (w 1 , w 2 ) transverse to said predetermined path that is different from a width (w 0 ) transverse to said predetermined path of the signal conductors and ground conductors in the inner layers. Further, a pitch (p 1 , p 2 ) between the outer layers is different from a pitch (p 0 ) between the inner layers.
