Abstract: An electrical connector adapted for electrically connecting an electronic package includes a base and at least a cam. The base has a receiving space for receiving the electronic package and at least a flange located on side of the receiving space. The cam is positioned on the flange. Each cam has a shelf and defines a first position and a second position. The cam is able to rotate between its first position and its second position for urging the electronic package to move, and when the cam is located in the second position, the shelf blocks the electronic package from a vertical direction motion.

Abstract: The present invention provides an electrical connector system for establishing electrical connection between an IC package (e.g. CPU) and a PCB. The electrical connector system comprises a base having opposing perimeter walls extending upwardly from peripheral edges of said base, a plurality of contacts and a protective plate. The perimeter walls provide a substantially continuous contact-receiving surface between said perimeter walls and the perimeter walls define a cavity therebetween above the contact-receiving surface. The plurality of contacts is arranged on the contact receiving-surface, and each including a contact engaging portion extending above the contact-receiving surface. The protective plate is floatably arranged on the perimeter walls of the base and substantially above the contact engaging portions and has a plurality of holes correlated to the contact engaging portions such that the contact engaging portion can extend through the hole when the plate is pushed toward the base.

Abstract: An electrical connector assembly (200) for connecting an electronic package with a circuit substrate, comprising a housing assembly (50) with a number of contacts (90) received therein, a lift-up device (20) assembled to the housing assembly (50) and moved from a first position to a second position, and a pick up cap (40) disposed between the housing assembly (50) and the lift-up device (20). The pick up cap (40) includes a body portion (401) and an wing portion (402) that can be assembled to the body portion (401). The wing portion (402) is moved relative to the body portion (401) when the lift-up device (20) is in a close position for preventing interference with the lift-up device (20).

Abstract: An IC socket comprises a base defining a plurality of passageways, a cover attached to the base and two actuating mechanisms disposed between the base and the cover. The cover has a plurality of apertures corresponding to the passageways. The two actuating mechanisms are disposed between the base and the cover to driving the cover moving along the base simultaneously.

Abstract: A contact, adapted for electrically connecting IC package and a printed circuit board, comprises a base, an upper spring arm and a lower spring arm. The upper spring arm is formed with an upper waist portion extending from a top edge of the base and a top end for electrically contacting with the IC package; and the lower spring arm is formed with a lower waist portion extending from a bottom edge of the base and a bottom end for electrically contacting with the printed circuit board. The bottom end has a width larger than that of the top end, and the lower waist portion has a width larger than that of the upper waist and defines a slot in a middle thereof.
