The invention is an electrical connector that minimizes signal skew caused by varying propagation times through different transmission paths within the connector, minimizes crosstalk caused by intermingling electric fields between signal contacts, and maximizes signal density within the connector. The electrical connector may include a plug and receptacle housing, plug contacts, receptacle contacts, and contact plates. The contact plates may include connecting contacts that electrically connect plug contacts to receptacle contacts. The electrical connector minimizes signal skew by maintaining substantially equal-length transmission paths within the connector through varying the lengths and positions of plug and receptacle contacts. The electrical connector minimizes crosstalk by surrounding the connecting contacts with electrical ground by placing the connecting contacts in grooves of the connecting plates. Placing the contacts in such grooves maximizes the signal density of the contact by enabling the contacts to be placed in close proximity with other contacts while minimizing crosstalk.
