ABSTRACT:
An LGA socket includes a socket body (10), a number of contacts planted in the socket body, a hollowed floating frame (50) floating on a number of push fingers (11) formed on the socket body, a stiffener (20) disposed right round the socket body and the floating frame, and a socket plate (40) and a load lever (30) respectively mounted to opposite ends of the stiffener. The floating frame is provided with a number of receiving sections (54) to hold an LGA package (60). The floating frame with the LGA package held thereon is vertically movable between a free state in which the conductive pads of the LGA package do not engage with the contacts, and a compressed state in which the conductive pads of the LGA package resiliently register with corresponding contacts. Thus, damage to the contacts during installation is avoided and reliable electrical connection is ensured.
