Problems solved by technology

In addition, electrical performance issues become more acute as the density of the signal conductors of the connector increases and the operating frequency increases
Such electrical performance issues can include, but are not limited to, crosstalk between closely spaced signal conductors

Embodiment Construction

[0060] One such technique for improving the performance of high speed electrical connectors may be to short together one or more conductive elements in the connector that are adapted to act as ground conductors. In one embodiment, such features include conductive members made by forming one or more cuts in a sheet of conductive material. The cutout may be arranged such that when the conductive member is disposed across the mating interface of the connector, the conductive member makes electrical contact with at least some of the ground conductors, but does not make electrical contact with any conductive elements suitable as signal conductors. For example, the cutouts may be aligned with the signal conductors at the mating interface such that each signal conductor extends through a corresponding cutout without making electrical contact with the conductive member. But alternatively or in addition, such conductive members may be integrated into the connector in the vicinity of th...

Abstract

An electrical connector comprises an insulative shell having a floor; a first plurality of contacts extending through the floor, wherein the first plurality of contacts are disposed in a plurality ofcolumns; a second plurality of contacts extending through the floor, wherein the second plurality of contacts are interspersed with the first plurality of contacts within the plurality of columns; anda conductive member adjacent the floor. The conductive member comprises a first plurality of openings, wherein the first plurality of contacts extend through the openings of the first plurality of openings; a second plurality of openings, wherein the second plurality of contacts extend through the openings of the second plurality of openings; and a first plurality of tabs, extending into openingsin the insulative shell.

Description

technical field [0001] The present disclosure relates generally to electrical interconnection systems, and more particularly to improving signal integrity in interconnection systems, particularly in high speed electrical connectors. Background technique [0002] Electrical connectors are used in many electronic systems. It is generally easier and more cost-effective to manufacture the system as separate electronic components, such as printed circuit boards (PCBs), which can be coupled together using electrical connectors. One known arrangement for joining several printed circuit boards is to use one printed circuit board as a backplane. Other printed circuit boards (called "daughter boards" or "daughter cards") can then be connected through this backplane. [0003] One known backplane is in the form of a printed circuit board on which a number of connectors can be mounted. Conductive traces in the backplane can be electrically connected to signal conductors in the connect...
