Impedance matched reduced cross talk electrical connector system

A low cross talk electrical signal transmission system comprising:

• at least four conductive paths formed by a first pair of conductors and a second pair of conductors;
• each pair of conductors being a part of a separate electrical circuit for conducting separate electrical signals;
• an electrical connector;
• first portions of each of said conductive paths being through said connector;
• said conductive paths being substantially parallel to one another through at least a part of said connector thereby causing pair to pair signal interference when an electrical signal is on at least one of said pairs;
• apparatus for reducing the pair to pair signal interference;
• said apparatus for reducing including a rearrangement of a second portion of at least one of said conductive paths resulting in the cancellation of a substantial amount of said interference;
• apparatus for reducing structural return loss;
• each pair includes a first and a second conductor;
• said first conductor of said first pair is adjacent to said second conductor in said second pair, and said second conductor of said first pair is adjacent to said first conductor in said second pair for the length of said conductive paths within said connector;
• said first conductor of said first pair is adjacent to said first conductor of said second pair, and said second conductor of said first pair being adjacent to said second conductor of said second pair for the length of said conductive paths within said apparatus for reducing interference;
• said apparatus for reducing return loss being a fifth conductor connected to said second conductor of said second pair and located adjacent to said first conductor of said second pair within said apparatus for reducing interference.

An electrical connector system comprising:

• a connector having at least four parallel adjacent contacts;
• two of said contacts being inner contacts and forming a first conductive pair;
• two other contacts adjacent to said inner contacts on the outside thereof forming a second conductive pair;
• a carrier;
• said carrier including four conductors;
• each conductor respectively connected to one of said contacts;
• said first contact of said first pair connected to said first conductor of said first pair;
• said second contact of said first pair connected to said second conductor of said second pair;
• said first contact of said second pair connected to said first conductor of said second pair;
• said second contact of said second pair connected to said second conductor of said second pair;
• for a substantial portion of the length of said carrier said first conductor of said second pair is adjacent to said second conductor of said first pair, and said second conductor of said second pair is adjacent to said first conductor of said first pair whereby pair to pair interference is substantially reduced in said system;
• said carrier including a fifth conductor;
• said fifth conductor connected to said first conductor of said second pair;
• said fifth conductor being adjacent to said second conductor of said second pair for improving characteristic impedance match within the complete system.

A low cross talk electrical connector system comprising:

• an electrical connector having at least two pairs of spaced apart electrical contacts thereby causing pair to pair cross talk when electrical signals are present on at least one of said pairs of said contacts;
• a carrier;
• said carrier connected to said electrical connector;
• said carrier including at least four conductors connected to said contacts;
• said carrier including apparatus for substantially reducing pair to pair cross talk originating in said connector;
• said carrier including a fifth conductor;
• said fifth conductor connected to one of said four conductors and being adjacent to another of said four conductors for reducing signal loss and improving return loss.
