  • Publication number: 20080220628
    Abstract: An electrical connector (1) for connecting a land grid array (LGA) chip with a printed circuit board (PCB) includes a housing (10), and terminals (11) received in passageways (104) of the housing. The housing has a base (100) and sidewalls (12, 14), the base and the sidewalls cooperatively defining a space therebetween for retaining the LGA chip. The base has a multiplicity of walls respectively between every two adjacent passageways along a length thereof, and four raised portions (102) extending upwardly around the base. A multiplicity of protrusions (106) is respectively extended upwardly from the walls. When a force is exerted down the LGA chip to make the LGA chip engage with the terminals, the protrusions and the four raised portions can support the force for separate the force without making the LGA chip deforming downwardly. This ensures that engagement between the connector and the LGA chip is accurate and reliable.

  • Publication number: 20080194124
    Abstract: A socket connector for connecting a post or ball wherein the female element grips the post with resilient prongs with end tips at low insertion force but positive contact is maintained and wherein attempted withdrawal is normally inhibited by increasing force applied to the post by the female element in response to the withdrawal force. The female element comprises a tube of resilient conductive material that has been sliced or helically partitioned into opposing helical prongs so as to allow the prongs of the connector to spirally open around the post or ball-like bump and mechanically grip the post or bump as the post or bump is inserted along the longitudinal axis of the tube. The tubular element may be made by forming helical prongs in the end of a tube in helical cuts from about a mid section to one end of the tube.
