An LGP connector comprises an insulative housing and a plurality of contacts. The housing defines a plurality of passageway sections for receiving the contacts therein. Each contact includes a soldering base for soldering the contact to a printed circuit board and an upper contact beam for electrically connecting the contact with an LGP chip, thereby electrically connecting the chip with the printed circuit board. Each contact comprises a pair of anti-rotation tabs extending from an end of the soldering base, and each passageway section transversely defines an anti-rotation cavity in a bottom face thereof and at a first side wall thereof for retaining the anti-rotation tabs of the contact.

[ What is claimed is:] [1.]1. A Land-Grid-Package (LGP) connector for connecting an LGP chip with a printed circuit board, comprising:an insulative housing including a top face for proximity to an LGP chip, a bottom face opposite the top face for proximity to a printed circuit board, a plurality of passageway sections extending through the housing from the top face to the bottom face, each passageway section having opposite first and second side walls and an anti-rotation cavity in the bottom face of the housing in communication with the passageway section; anda plurality of contacts received in the passageway sections, respectively, each contact including a planar horizontal soldering base for being located near the bottom face of the housing for soldering to the printed circuit board, and an upper contact beam extending upwardly and forwardly from a rear end of the soldering base near the first side wall toward the second side wall of the passageway section and terminating at a free end for engaging with the LGP chip, said free end being located near the second side wall of the passageway section and above the soldering base of the contact, an anti-rotation mechanism extending from the soldering base for fitting within the anti-rotation cavity, and means extending from the soldering base for having an interference fit with the housing at the second side wall of the passageway section;wherein the anti-rotation mechanism is a pair of anti-rotation tabs extending rearwardly from an end of the soldering base of the contact parallel to each other for fitting within the anti-rotation cavity, and wherein the anti-rotation cavity is transversely defined in the bottom face of the housing adjacent the first side wall for receiving the anti-rotation tabs of the contact;wherein the means at the second side wall of the passageway section comprises a bifurcated junction portion having a pair of retention arms;wherein each contact comprises a lower beam extending from a front end of the soldering base to a middle of the junction portion for supporting the contact between the retention arms;wherein each passageway section defines a pair of recesses in opposite sides and adjacent to the second side wall thereof for holding the junction portion therein;wherein a plurality of barbs are provided on opposite sides of the junction portion for interferentially engaging with the corresponding recesses.
