Abstract:
A land grid array or ball grid array type integrated circuit socket comprising:(a) a metal basin which is a box body having a bottom face and multiple side walls, two opposite side walls of the metal basin being respectively formed with latch perforations, each latch perforation having an opening section and a latch section communicating with the opening section; (b) an insulating board snugly inlaid in the metal basin, the insulating board having multiple insertion holes passing through the insulating board; (c) multiple conductive members which are one by one inlaid in the insertion holes of the insulating board and passed through the metal basin to contact with multiple corresponding land grid array conductive contacts of a circuit board and contact with multiple land grid array or ball grid array terminals of the integrated circuit, whereby the conductive contacts of the circuit board are electrically connected with the terminals of the integrated circuit; (d) an upper cover having a first side, a second side opposite to the first side, a third side connected with one end of the first side and second side and a fourth side connected with the other end of the first side and second side, the upper cover further including multiple latch tenons which are disposed on the first and second sides and can be correspondingly placed into the opening section of the latch perforation of the metal basin and latched in the latch section, whereby the upper cover is latched on the metal basin to cover upper side thereof, the upper cover having a receiving section for accommodating the integrated circuit therein, the receiving section including: a first locating section disposed on the first side, the first locating section being integrally downward bent from the upper cover and protruding from the bottom face of the upper cover, whereby when the integrated circuit is attached to the bottom face of the upper cover, the first locating section is adjacent to a first edge of the integrated circuit; a second locating section disposed on the second side, the second locating section being integrally downward bent from the upper cover and protruding from the bottom face of the upper cover, the second locating section being adjacent to a second edge of the integrated circuit; a third locating section disposed on the third side, the third locating section being integrally downward bent from the upper cover and protruding from the bottom face of the upper cover, whereby when the integrated circuit is attached to the bottom face of the upper cover, the third locating section is adjacent to a third edge of the integrated circuit; and a fourth locating section disposed on the fourth side, the fourth locating section being integrally downward bent from the upper cover and protruding from the bottom face of the upper cover, whereby when the integrated circuit is attached to the bottom face of the upper cover, the fourth locating section is adjacent to a four edge of the integrated circuit; and (e) clamping leaf springs mounted on the second side of the upper cover for resiliently pressing the second edge of the integrated circuit, whereby by means of the first locating section of the first side of the upper cover and the clamping leaf springs disposed on the upper cover, the opposite first and second edges of the integrated circuit are clamped to hold the integrated circuit under the bottom face of the upper cover.
