Patent number: 7429176Abstract: A modular board to board mezzanine ball grid array BGA connector includes a plug, a receptacle and if needed an adapter. The plug and the receptacle can be made form the same base pieces to accommodate different stack heights. If a greater stack height is needed, spacers can be used in the plug and the receptacle to accommodates a greater selected stack height. The plug and the receptacle both include a base having an interstitial diamond recesses in which the solder balls are disposed and in which one end of a contact is inserted. The plug may further include a plug cover that can be connected to the base, and the receptacle may include a receptacle cover that fits over its base. The plug can have a plug contact assembly, and the receptacle can have a receptacle contact assembly. The plug and the receptacle can be mated by mating the plug cover to the receptacle cover and the receptacle contacts to the plug contacts.Type: GrantFiled: February 11, 2004Date of Patent: September 30, 2008Assignee: FCI Americas Technology, Inc.Inventors: Douglas Michael Johnescu, Craig W. Clewell, Lewis R. Johnson

Patent number: 7422444Abstract: An electrically-conductive contact for an electrical connector is disclosed. Such a contact may include a lead portion, an offset portion extending from an end of the lead portion, and a mounting portion that may extend from a distal end of the offset portion. The lead portion and the distal end of the offset portion may each define an imaginary plane that may intersect at a non-zero, acute angle. An electrical connector that is suitable for orthogonal connector applications may include a connector housing securing two such electrical contacts. The distance between the respective mounting portions of the two such contacts may be defined independently of the contact pitch.Type: GrantFiled: February 28, 2007Date of Patent: September 9, 2008Assignee: FCI Americas Technology, Inc.Inventor: Douglas Michael Johnescu

Patent number: 6758702Abstract: An electrical connector comprises a housing having a retention structure, and a plurality of contacts extending through said housing. Each contact has a medial section, a mounting portion extending from one end of the medial section, and a compressive mating portion extending from another end of the medial section and having a distal end. The retention structure of the housing engages the distal ends of the compressive mating portions of the contacts to preload the contacts. The contacts extend through the housing and exhibit a preload. A fusible element is secured to each respective one of the contacts.Type: GrantFiled: February 14, 2001Date of Patent: July 6, 2004Assignee: FCI Americas Technology, Inc.Inventor: Douglas Michael Johnescu
