Embodiment Construction

[0017] The present invention relates to a backplane connector system for connecting to one or more substrates. The backplane connector system is operable at high speeds (eg, at least up to 25 Gbps) while, in some embodiments, providing high pin density (eg, at least 50 pairs of electrical connectors per inch). In one embodiment, such as figure 1 As shown, the backplane connector system 102 may be used to connect a first substrate 104, such as a printed circuit board, to a second substrate 106, such as another printed circuit board, in parallel or perpendicular relationship. As will be described in more detail below, embodiments of the disclosed connector system may include a ground shield structure that substantially encapsulates electrical connector pairs that may pass through backplane footprints, Differential electrical connector pairs for backplane connectors and / or daughter card traces. The ground structure of these packages, along with the dielectric fill material in t...

Abstract

An electrical connector system for mounting a substrate comprises a plurality of wafer assemblies. Each of the wafer assemblies comprises a center frame (208), a first array of electrical contacts (210), a second array of electrical contacts (212), and a plurality of ground shields. The center frame (208) defines a first side (218) and a second side (220) opposing the first side, wherein the first and second sides each define a plurality of electrical contact channels. At least one of the first and second sides defines a plurality of ground shield channels (224) that are positioned on the wafer assembly (206) such that each ground shield channel is separated from another ground shield channel by an electrical contact channel of the plurality of electrical contact channels (222). The first array of electrical contacts (210) is positioned within the plurality of electrical contact channels (222) of the first side (218), the second array of electrical contacts (212) is positioned within the plurality of electrical contact channels (226) of the second side (220), and the plurality of ground shields is positioned within the plurality of ground shield channels (224).

Description

technical field [0001] The present invention relates to an electrical connector system, and more particularly to an electrical connector system comprising a plurality of board-like assemblies Background technique [0002] Backplane connector systems are typically used to connect a first substrate, such as a printed circuit board, to a second substrate, such as another printed circuit board, in parallel or perpendicular relationship. As electronic components decrease in size and generally become more complex, it is often desirable to fit more components into a smaller space on a circuit board or other substrate. Accordingly, it would be desirable to reduce the spacing between electrical terminals in a backplane connector system and to increase the number of electrical terminals accommodated in a backplane connector system. However, as the speed of electronic signals increases, the reduced spacing between electrical terminals increases the likelihood of electrical crosstalk a...
