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.
