Title:
DIFFERENTIAL PAIR SIGNAL CONTACTS WITH SKEW CORRECTION
Document Type and Number:
WIPO Patent Application WO/2017/123689
Kind Code:
A3
Abstract:
An electrical connector configured for differential pairs with low in-pair skew. The connector may comprise lead frame assemblies, such as insert molded lead frame assemblies, with adjacent conductors configured for reduced skew by distributing skew correction throughout the transmission path through the lead frame assembly. Elongated air gaps are formed in a side of the housing, exposing the longer conductor of each pair. The elongated air gap may span the entire length of the arc of a longer conductor of each pair. The width of this air gap may be different for different pairs in the lead frame assembly and may be selected to cancel or prevent in-pair skew from arising. The width for each pair may be selected to tune the effective dielectric constant of the longer conductor such that its electrical length matches that of the shorter conductor.
