Abstract

An orthogonal electrical connector system includes vertical electrical connectors that are configured to be mated to each other so as to place respective pluralities of first and second substrates that are oriented orthogonal to each other in data communication with each other through the mated electrical connectors. Other connector systems are also disclosed.
