US Patent:

7794278, Sep 14, 2010

Filed:

Apr 4, 2008

Appl. No.:

12/062581

Inventors:

Thomas S. Cohen - New Boston NH, US
Brian Kirk - Amherst NH, US
Jason E. Chan - Nashua NH, US
Andreas C. Pfahnl - Goffstown NH, US
David Manter - Windham NH, US

Assignee:

Amphenol Corporation - Wallingford CT

International Classification:

H01R 13/648

US Classification:

43960709, 439108

Abstract:

An electrical interconnection system with high speed, differential electrical connectors. The connector is assembled from wafers containing columns of conductive elements, some of which form differential pairs. Each column may include ground conductors adjacent pairs of signal conductors. The ground conductors may be wider than the signal conductors, with ground conductors between adjacent pairs of signal conductors being wider than ground conductors positioned at an end of at least some of the columns. Each of the conductive elements may end in a mating contact portion positioned to engage a complementary contact element in a mating connector. The mating contact portions of the signal conductors in some of the pairs may be rotated relative to the columns. The printed circuit board to which the differential signal connector is mounted may be constructed with elongated antipads around pairs of signal conductors.

Inventors:

Jason Edward Chan - Nashua NH, US
Jose Ricardo Paniagua - New Market NH, US

Assignee:

Amphenol Corporation - Wallingford CT

International Classification:

H05K 1/11

US Classification:

174262, 361785

Abstract:

An electrical signal connection, an electrical signaling system, and a method of connecting printed circuit boards. The electrical signal connection having a first conductive via and a second conductive via disposed in a first printed circuit board. A first conductive trace with a first end and a second end has the first end electrically coupled to the first conductive via at a first distance from the top surface of the first printed circuit board. The second end of the first conductive via is electrically coupled to the second printed circuit board. A second conductive trace with a first end and a second end has the first end being electrically coupled to the second conductive via at a second distance from the top surface of the first printed circuit board. The second end being is electrically coupled to the second printed circuit board.
