Embodiment Construction

[0051] The inventors recognize and favor connector designs that enhance the performance of high density interconnect systems, particularly interconnect systems carrying very high frequency signals necessary to support high data rates. The connector design provides effective shielding in the mating area of ​​the two connectors. When two connectors are mated, the shield separates the mating parts of the conductive elements that carry separate signals. In some embodiments, the shield may substantially surround a mating portion of a signal-carrying conductive element, which may be a pair of conductive elements of a connector configured to carry a differential signal.

[0052] The inventors recognize and agree that such shielding, while effective at low frequencies, may not work as intended at high frequencies. To enable effective isolation of the signal conductors at high frequencies, the connectors may include a lossy material selectively positioned within a mating area of ​​at ...

Abstract

An interconnection system with lossy material of a first connector adjacent a ground conductor of a second connector. The lossy material may damp resonances at a mating interface of the first and second connectors. In some embodiments, the lossy material may be attached to a ground conductor of the first connector. In some embodiments, the lossy material may be shaped as horns that extend along acavity configured to receive a ground conductor of a mating connector.

Description

technical field [0001] This patent application generally relates to interconnection systems for interconnecting electronic components, such as interconnection systems including 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 individual electronic assemblies, such as printed circuit boards ("PCBs"), that can be connected together by electrical connectors. A known arrangement for connecting several printed circuit boards is to use one printed circuit board as the backplane. Other printed circuit boards called "daughter boards" or "daughter cards" can be connected through the backplane. [0003] One known backplane is a printed circuit board on which a number of connectors can be mounted. Conductive traces on the backplane can be electrically connected to signal conductors in the connectors so that signals can be routed between the conne...
