Matched high-speed interconnector assembly
An assembly for use in a system comprising a plurality of pairs of conductors, and a plug/receptacle for terminating the cable at a rear end thereof, a plurality of evenly spaced terminal contacts/tines respectively exposed along a front of the plug body/within the receptacle, arranged in parallel, and a printed circuit board assembly comprising a plurality of pairs of traces interconnecting each conductor of the pairs of conductors with respective ones of the terminal contacts/tines. A center pair of the conductors is attached to a first pair of the terminal contacts/tines and a second pair of conductors is attached to a second pair of the terminal contacts/tines. The center pair of terminal contacts/tines is positioned between the second pair of contacts/tines wherein in operation a current flow in the center pair of terminal contacts/tines is in a direction substantially away from the second pair of terminal contacts/tines.
1. A cable connector assembly for use with a receptacle comprising a plurality of evenly spaced tines in a telecommunications system, the assembly comprising:
a cable comprising a plurality of pairs of conductors; and
a RJ-45 style plug comprising a plug body for terminating said cable at a rear end thereof, a plurality evenly spaced terminal contacts exposed along a front of said plug body and arranged in parallel, and a printed circuit board assembly comprising a plurality of pairs of conductive traces electrically interconnecting each conductor of said pairs of conductors with respective ones of said terminal contacts, wherein a first pair of said pairs of conductors is electrically interconnected with respective ones of a center pair of said terminal contacts and a second of said pairs of conductors is electrically interconnected with respective ones of a second pair of said terminal contacts, said center pair of terminal contacts positioned between and immediately adjacent to each of said terminal contact of said second pair of terminal contacts;
wherein when said plug is inserted into the receptacle, each of said plurality of terminal contacts comes into electrical contact with a respective one of the plurality of tines along a contact region, wherein each of said terminal contacts comprises a first end and a second end and wherein each of said center pair of terminal contacts is electrically interconnected with a respective trace towards a first end and each of said second pair of terminal contacts is electrically interconnected with a respective trace towards a second end and such that a current flow between said plug and the receptacle in said center pair of terminal contacts is in a direction substantially opposite to that of said second pair of terminal contacts to achieve the preferred compensation.
2. The cable connector assembly of claim 1 , wherein said plurality of terminal contacts comprises four pairs of contacts each comprising a first end and wherein a third pair and a fourth pair of said terminal contacts are positioned respectively on opposite sides of said center pair and second pair of terminal contacts and further wherein each of said terminal contacts is electrically interconnected towards said first end with a respective trace such that a current flow between said plug and the receptacle in said third and fourth pairs of terminal contacts is in substantially the same direction as said current flow in said center pair of terminal contacts.
3. The cable connector assembly of claim 2 , wherein each of said third and fourth pairs of terminal contacts is electrically interconnected to its respective trace at said first end whereby said current flow between said plug and the receptacle in said third and fourth pairs of terminal contacts is in a direction substantially the same as that of said center pair of terminal contacts.
4. The cable connector assembly of claim 1 , wherein said printed circuit board assembly comprises a flexible printed circuit board.
5. The cable connector assembly of claim 4 , further comprising a support and wherein said flexible printed circuit board is bent to form a fold towards a middle thereof over said support such that a first end of said flexible printed circuit board lies opposite a second end of said flexible printed circuit board further wherein said traces come into electrical contact with their respective terminal contacts adjacent said fold.
