Abstract:
An IC socket comprising:a multitude of elastic contact pins separately constructed with one another and arranged to form an array;a socket body through which respective lower end sections of said contact pins are inserted to be movably supported thereby;a floating member which is vertically movably held above said socket body and by which respective upper end sections of said contact pins are movably supported; anda cover member constructed to be fitted to said floating member so as to press said floating member toward said socket body,wherein the upper end section and the lower end section of each of said contact pins are aligned to one another with intervention of an arc-shaped middle section, with an upper corner and a lower corner being formed where the upper end section and the lower end section meet the middle section, respectively, so as to limit movement of the upper end section and the lower end section with respect to said socket body and said floating member, respectively;wherein said socket body is adapted to be fixed to a printed circuit board by fixing means so that the lower end sections of said contact pins abut on respective mate electrodes on the printed circuit board;wherein said floating member is provided with:a multitude of guide means for regulating the amount of projection of the upper end sections of said contact pins from said floating member in cooperation with the upper corners of said contact pins; anda container section adapted for containing an IC package by bringing a multitude of terminals of the IC package into contact with the upper end sections of said multitude of contact pins, respectively, andwherein where said cover member is fitted to said floating member and pressed down upon the IC package being put in said container section, contact at predetermined pressure is obtained between the lower end sections of said contact pins and said mate electrodes of the printed circuit board and between the upper end sections of said contact pins and the terminals of the IC package, respectively.
