Abstract: A test connector (1) includes a base (10), a cover (20), a metallic stiffener (70), two operating members (60), and a lid (30). An opening (703) is defined in the stiffener for receiving the cover therein. Two spaced projections (704) are formed on one end of the stiffener. Two receiving grooves (705) are defined in bottoms of the projections respectively. Each operating member comprises a first operating lever (601) engaged with the receiving grooves via a first shaft (603), 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 so that the operating members actuate the stiffener and the cover to move. When the cover moves to make the terminals connect a CPU during applying an unduly force on the lid, the metallic stiffener can protect the plastic cover from damage.

Abstract: A burn-in socket assembly (1) includes a base (10) receiving an IC and a number of contacts, a slider member (20) mounted onto the base and capable of moving along the base, a pair of actuation members (30) assembled onto the base, and a cover (40) assembled onto the actuation members and capable of moving up and down. The base forms a pair of receiving elements (141) on front and end sides respectively. Each receiving element includes a body portion (142), a pair of spaced top portion (143) each having slits (144) extending therethrough and an aperture (145) extending therethrough. A sensor is received in the aperture to provide signals to a controller during being operated at high temperature. The controller can reliably control the temperature of the whole assembly in light of the signals from the sensor, thereby avoiding damage of the IC by exorbitant temperature.

Abstract: An socket (20) includes a base (30), a cover (50) slidably mounted on the base, a lid (60) attached to the base by plates (70A). The cover has guiding protrusions (56A) mated with guiding grooves (72A) of the plates, respectively. The guiding grooves each include first and second parts (705A, 707A) communicated smoothly with each other. A center line of the first part departs radially offsetly from a center point of the plate so that either of opposite sides of the first part can urge the guiding protrusion therein to make the cover move relative to the base between open and close positions. A center line of the second part has an arc shape whose center point is the center point. Thus, neither of opposite sides of the second part can actuate the guiding protrusion and the cover is kept immovable in the close position when the lid is over-urged.
