Abstract: A test connector (10) includes a connector body (30) with terminals therein, a lid (20), four guiding mechanisms (50), and two pressing mechanisms (40). The connector body comprises an outer housing (34) and an inner housing (32) for receiving an IC package (80). Each pressing mechanism comprises a first shaft (44) attached to the lid, a second shaft (46) mounted to the outer housing, two operating levers (42) engaged between the first and second shafts, and a leaf spring (48) mounted to the first shaft. When the lid is in an upper position, the pressing mechanisms are in a first position in which the leaf springs are disengaged from the IC package, while when the lid is in a lower position, the pressing mechanisms are moved to a second position in which the leaf springs are engaged with the IC package thereby the IC package can be tested.

Abstract: A socket connector (1) includes a base (10), a cover (20), two operating members (60), a lid (30), and four coil springs (40) received between the lid and the base. The base defines passageways (1010) receiving terminals therein. Each operating member includes a first operating lever (601) engaged with the cover, and a second operating lever (602) engaged with the base. The lid is engaged with the operating members for pivotably moving the first and second operating levers thereby the operating members actuating the cover to move in a horizontal direction. When no external force is exerted on the lid, the terminals in the base permit zero insertion force insertion and removal of the leads of the CPU, and when the lid is vertically pushed down, the operating members actuate the cover to move relative to the base thereby connecting the terminals with leads of the CPU.

Abstract: An IC socket (1) includes a base (10), a cover (11) pivotally mounted to one side of the base, and a plurality of electrical contacts received in the base for electrically connecting with a burn-in board. The base has six projecting members (102) to form a container for receiving an IC therein. The cover includes a frame (110) defining an opening (1101) a middle thereof, and a pressing portion (111). The pressing portion comprises a pair of bearing springs (1110), and a pair of bars (1111) interconnecting corresponding opposite ends of the bearing springs. The bars are embedded in the rear and front sides of the frame, and the bearing springs are located in opposite lateral sides of the opening. When the cover firmly engaging with the base, the bearing springs press the IC on the contacts. The IC socket thus electrically connects the IC with the burn-in board.
