1. An electrical connector comprising:
- an electrically insulative connector housing; and
an array of gender-neutral electrical contacts supported by the connector housing so as to define a mounting end configured to mount onto a substrate and a mating end that is disposed opposite the mounting end, each of the electrical contacts of the array of electrical contacts defining first and second opposed broadsides and first and second opposed edges, the broadsides longer than the edges, the array of electrical contacts defining a plurality of rows that are spaced along a column direction and a plurality of columns that are spaced along a row direction, such that edges of adjacent ones of the electrical contacts of each row face each other, and the broadsides of adjacent ones of the electrical contacts of each column face each other;
wherein each of the mating ends are curved so as to define a curvature, and the electrical contacts define first, second, and third electrical contacts that are aligned along the column direction, such that the second electrical contact is adjacent and disposed between the first and third electrical contacts, the curvature of the mating ends of the first and second electrical contacts face each other, and the curvature of the mating ends of the second and third electrical contacts face away from each other, such a first distance is defined along the column direction from the mating end of the first electrical contact to the mating end of the second electrical contact, and a second distance is defined along the column direction from the mating end of the second electrical contact to the mating end of the third electrical contact, and the first distance is less than the second distance.

Abstract
An electrical connector assembly includes first and second mezzanine electrical connectors that include respective first and second arrays of electrical contacts. The electrical contacts can be receptacle, or one can be a plug and the other can be a receptacle. Each electrical connector can further include at least one alignment member that cooperate to align the first and second arrays of electrical contacts relative to each other. Each electrical connector can further include at least one orientation member that allows the first and second electrical connectors to mate when in a predetermined orientation relative to each other.

12. An electrical connector comprising:
-
a connector housing; and a plurality of electrical contacts supported by the connector housing, each electrical contact defining
1) first and second opposed broadsides spaced from each other along a longitudinal direction and
2) first and second opposed edges spaced from each other along a lateral direction that is perpendicular to the longitudinal direction, the broadsides being longer than the edges in a plane defined by the longitudinal and lateral directions;wherein each electrical contact only touches the connector housing at two locations along the lateral direction, without touching the housing along the longitudinal direction, and each of the two locations defines a contact area of 0.001 square millimeters to 0.015 square millimeters. - View Dependent Claims (13, 14, 15, 16, 17)

18. An electrical connector comprising:
-
a connector housing including a housing body and a plurality of retention cavities that extend through the housing body, each retention cavity defined by at least one inner wall of the housing body, each retention cavity defining cross-sectional dimension along a select direction; an array of electrical contacts supported by the connector housing, the array of electrical contacts including at least two rows of electrical contacts that are spaced from each other and extend along a first direction, and at least two columns of electrical contacts that are spaced from each other and extend along a second direction that is substantially perpendicular to the first direction, each of the at least two rows of electrical contacts intersecting each of the at least two columns of electrical contacts; and each of the electrical contacts define a mating end, a mounting end opposite the mating end, a respective solder ball fused to each of the electrical contacts at the respective mounting ends, and a lead portion that extends between the mating end and the mounting end, wherein each of the electrical contacts further includes a pair of retention wings that project out from opposite sides of the lead portion to respective free distal tips that are spaced from each other a distance along the select direction that is greater than the cross-sectional dimension such that the free distal tips are press-fit into respective ones of the retention cavity, and an entirety of the electrical contact within the retention cavity is spaced from the housing body along a second direction that is perpendicular to the select direction so as to define a gap between the lead portion and the housing body in the second direction that extends from one of the retention wings to the other of the retention wings. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
