Abstract

Electrical connectors that are mating compatible with the MicroTCA® standard and configured to be mounted to an underlying substrate are provided. Certain of the electrical connectors can be configured to be mounted to a substrate configured in accordance with the MicroTCA® press fit footprint. Additionally, electrical connectors that are mating compatible with the MicroTCA® standard and configured to be mounted to respective alternative footprints, and substrates configured in accordance with the respective alternative footprints are provided. The disclosed electrical connectors and corresponding substrate footprints can operate to transmit data at speed up to and in excess of 25 Gigabits per second.

Dependent claims

A card edge electrical connector comprising:

a connector housing;
a plurality of electrical signal contacts supported by the connector housing, each electrical signal contact including a contact body that defines a mating end and a mounting end, wherein respective pairs of the plurality of electrical signal contacts define differential signal pairs,
a plurality of ground plates supported by the connector housing, each of the plurality of ground plates including a first ground mating end that defines a first ground flow return path and a second ground mating end that defines a second ground flow return path, wherein the first and second ground flow return paths of at least one ground plate of the plurality of ground plates are substantially symmetrical with respect to one another,
wherein the mating ends of the plurality of electrical signal contacts and the first and second ground mating ends of the plurality of ground plates collectively define one hundred seventy mating ends that are spaced along two rows that extend along a row direction, the one hundred seventy mating ends defining a 0.75 mm column pitch, and the connector housing supports each of the plurality of electrical signal contacts and the plurality of ground plates such that only two differential signal pairs are disposed between successive ground plates.

An electrical connector comprising:

a connector housing;
a first vertical electrical signal contact configured to be supported by the connector housing, the first vertical electrical signal contact including a first contact body that defines a first mounting end and a first mating end that is opposite the first mounting end, the first mounting end carrying a first mounting element configured to be placed in electrical connection with a printed circuit board, and the first vertical electrical signal contact defining first and second broadsides and first and second edges that extend between the first and second broadsides,
a second vertical electrical signal contact configured to be supported by the connector housing, the second vertical electrical signal contact including a second contact body that defines a second mounting end and a second mating end that is opposite the second mounting end, the second mounting end carrying a second mounting element configured to be placed in electrical connection with the printed circuit board, and the second vertical electrical signal contact defining first and second broadsides and first and second edges that extend between the first and second broadsides, wherein the first mating end and the second mating end are spaced from each other along a first direction that is substantially perpendicular to the first and second broadsides of the first and second vertical electrical signal contacts,
wherein each of the first and second contact bodies is twisted such that the broadsides at the first mounting end is angularly offset with respect to the broadsides at the first mating end, the broadsides at the second mounting end is angularly offset with respect to the broadsides at the second mating end, and the first mounting element is aligned with the second mounting element along a second direction that is substantially perpendicular to the first direction.
