Publication number: 20040106317Abstract: An electrical connector assembly includes an electrical connector (1) and a card (5) having a wedge (52) to be inserted into the connector. The connector includes a dielectric housing (2) having a head section (20) in which a number of contacts (3) retained therein and a bottom plate (22) extending rearwardly from a lower portion of the head section. The head section defines a receiving slot (200) to divide the head section into an upper wall (25) and a lower wall (26). The contacts include engaging portions (30) extending downwardly into the receiving slot for electrically contacting with the card. The lower wall of the head section defines an inclined plane (260) to cooperate with the wedge to maintain the card constantly parallel to the bottom plate of the housing during the insertion of the card.Type: ApplicationFiled: December 3, 2002Publication date: June 3, 2004Inventor: James R.

Patent number: 5860819Abstract: A connector assembly 10 includes a receptacle 12 and a pin header 14 adapted to mate with the receptacle. A row of resilient enhancement contacts 18 extend through a backplane 16 and is held in place in fixed relation to the receptacle. The receptacle and pin header each comprise an insulative body portion 20, 19, respectively. The receptacle 12 comprises contact pins extending through body portion 20 and arranged in three rows of thirty-two pins per row (3.times.32). The pin header 14 likewise comprises contact pins extending through body portion 19 and arranged in three rows of thirty-two pins per row. The pin header 14 includes a row of contact strips 24 disposed on an outer surface of body portion 19. The contact strips are preferably of uneven lengths to provide for stage mating between the contact strips 24 and corresponding enhancements pins 18.Type: GrantFiled: December 2, 1996Date of Patent: January 19, 1999Assignee: BERG Technology, Inc.Inventors: William Arthur Northey, James R.
