Abstract

A connector for use with high-speed signals. The connector has a housing, which includes conductive elements held in a row by a housing. Each conductive element includes a thinner portion and a thicker portion. The conductive elements are configured to make contact with a mating component at the thicker portions. The thinner portions are closer to mating ends of respective conductive elements than respective thicker portions. The housing is configured to provide voids selectively disposed underneath the conductive elements. Such a configuration increases impedances for the conductive elements at locations that would otherwise have lower impedance and therefore reduces impedance variations along signal transmission paths. Such a configuration can also reduce stub size and therefore reduce insertion loss. Such a configuration meets signal integrity requirements in connectors designed for 64 Gbps and beyond, while conforming to a standard that constrains mating and mounting interfaces.

Dependent claims

An electrical connector, comprising:

a housing comprising a tongue portion, the tongue portion comprising a plurality of voids;
and
a plurality of conductive elements held by the housing, each of the plurality of conductive elements comprising a thicker portion and a thinner portion, wherein, for each of the plurality of conductive elements:
the thinner portion is disposed adjacent a respective void of the plurality of voids of the tongue portion so as to reduce impedance variations along signal transmission paths;
the conductive element is configured to make contact with a mating component at the thicker portion;
and
the thinner portion is closer to a mating end of the conductive element than the thicker portion.

4 more elements

An electrical connector, comprising:

a housing comprising a base portion extending in a longitudinal direction, a tongue portion extending from the base portion in a mating direction perpendicular to the longitudinal direction;
and
a plurality of conductive elements each comprising a first portion held in the base portion of the housing, a second portion extending from the first portion and held on the tongue portion, and a third portion extending from the first portion and out of the base portion of the housing, wherein:
the tongue portion of the housing comprises a plurality of voids;
each of the plurality of conductive elements is retained by edges of the second portion of the conductive element over a respective void of the plurality of voids;
and
for each of the plurality of conductive elements, the second portion comprises:
a first subportion disposed over the respective void of the plurality of voids, and
a second subportion thicker than the first subportion in a vertical direction perpendicular to the longitudinal direction and the mating direction.
