Abstract
An electrical connector for transferring a plurality of differential signals between electrical components. The connector is made of modules that have a plurality of pairs of signal conductors with a first signal path and a second signal path. Each signal path has a pair of contact portions, and an interim section extending between the contact portions. For each pair of signal conductors, a first distance between the interim sections is less than a second distance between the pair of signal conductors and any other pair of signal conductors of the plurality. Embodiments are shown that increase routability.
Claims11
A printed circuit board for receiving differential pair contact tail portions of a connector, the printed circuit board comprising:
- at least one ground plane having pairs of apertures configured to receive the differential contact tail portions of the connector;
- and
- for each pair of apertures corresponding to a differential pair, an area surrounding he pair of apertures is free of the ground plane layer and each aperture of the pair is electrically isolated from the other.
A printed board for receiving differential pair contact portions of a connector, the printed circuit board comprising:
- a surface exposing pairs of apertures configured to receive the differential pair contact tail portions of the connector;
- ground plane layers;
- for each pair of apertures corresponding to a differential pair, an area surrounding the pair of apertures is free of the ground plane layers and each aperture of the pair is electronically isolated from the other;
- and
- for the pairs of apertures, and area between adjacent pairs of apertures includes the ground plane layers.
