ABSTRACT:
A land grid array connector (10) for electrically connecting a CPU package to a printed circuit board includes a housing (30) having a top surface (320) and a number of terminals received in passageways (31) of the housing. Each of the terminals has a retention portion (52), a spring arm (54) extending from the retention portion beyond the top surface. A contacting portion (58) is formed on a topmost part of the spring arm for electrically mating with a corresponding pad formed on a bottom of the CPU package. A plurality of protrusions (324) is formed on the top surface for protect the terminals from being accidental damaged, A common supporting surface (326) is formed cooperatively by the protrusions, above the contacting portion in a direction perpendicular to the top surface. This can protect the contacting portion of the terminal from being collided. As a result reliable electrical connection between the package and contacts of the land grid array connector is secured.
