[embodiment]

See also Fig. 2 and Fig. 3; the utility model socket connector 1 is to be used for accepting microprocessor chip (not shown) and to be incorporated on the circuit board (not shown); electric connection between chip current-carrying part and circuit board corresponding circuit is provided, and it comprises pedestal 10, lid 12, conducting terminal 19, drive member 16 and protection member 14.

Pedestal 10 is made and rectangular plate body shape by insulating material, it runs through and is provided with some terminal accommodation holes separated from one another 101, accommodate corresponding conducting terminal 19 respectively, middle position at pedestal 10 1 ends is provided with first groove 102, these first groove, 102 bottom center run through pedestal 10 and are provided with circular seat hole 1021, are used for accommodating the counterpart of drive member 16.

Lid 12 is connected on the pedestal 10 and can changes between enable possition and make position, be provided with a square aperture 121 at lid 12 middle bodies, be provided with a protuberance 122 in the extension of lid 12 1 ends, be provided with the lid hole 123 corresponding with the seat hole 1021 of pedestal 10 in these protuberance 122 middle parts, this lid hole 123 is made up of two different semicircle orifices of diameter, is formed with two block walls 1231 perpendicular to lid 12 surfaces in the junction of two semicircle orifices.Some through holes 124 run through lid 12 and align with the terminal accommodation holes 101 of pedestal 10 respectively, therefore, the pin of microprocessor chip (not shown) can pass the through hole 124 of lid 12 and enter in the terminal accommodation holes 101 of pedestal 10, with accommodate conducting terminal inside 19 and electrically contact.In addition, lid 12 is concaved with second groove (not shown) near first groove, 102 positions of the corresponding pedestal 10 of pedestal 10 1 ends.
