US 2026/0188955 A1 · MOUNTING INTERFACE FOR HIGH DENSITY, HIGH SPEED ELECTRICAL CONNECTOR

Abstract

A high speed, high density electrical connector. The connector includes conductive elements for carrying signals, such as differential signals, with compliant portions for making pressure mount connectors. The distal ends of the signal conductors may have, in one portion a radius of curvature that provides suitable pressure for mounting to a substrate and in other portions, a larger radius of curvature, which results in a desired impedance profile. The compliant portions may be configured to establish desired signal current flow and desired ground current in shields bounding the signal conductors, particularly adjacent to the compliant portions. The compliant portions may have structures that more evenly distribute rotation over the length of the compliant portion. Such techniques facilitate manufacture of closely spaced signal units that each carry a signal with high signal integrity and low crosstalk at 100 GHz or above to support data rates of 224 Gbps and beyond.

Dependent claims

An electrical connector, comprising:

a pair of signal conductors having contact tails adapted for connection to a surface of a substrate in an insertion direction, wherein each of the contact tails comprises:
a plurality of segments spaced from one another in the insertion direction, a first segment of the plurality of segments comprising a first tab protruding towards a second segment of the plurality of segments, wherein:
the plurality of segments are configured to compress along the insertion direction when the contact tail is pressed against the surface of the substrate in the insertion direction;
the plurality of segments are configured to rotate about an axis parallel to the insertion direction when compressed;
and
the first tab is configured to limit movement of the first segment and the second segment toward one another when the plurality of segments are compressed.
