An IC socket (10) includes an insulative housing (12) mounted on a burn-in board, a plurality of conductive contacts (14) received in the housing. The housing defines a recessed area (120) bounded by two pairs of sidewalls (122), the recessed area defining a plurality of passageways therein. One of the sidewalls fabricates a receiving channel (1220) substantially parallel to an upper surface of the recessed area and a fastening channel (1222) substantially perpendicularly communicating with the receiving channel. A bolt (16) is screwed in the fastening channel. When the IC socket is used, a sensor (20) is received in the receiving channel and restricted in the proper position by the bolt screwed in the fastening channel.

An electrical connector includes a housing (2). A floor (20) is defined in a middle of the housing and a plurality of side walls (22) is defined therearound. The side walls and the floor cooperatively define a substantially rectangular cavity (24) therebetween. A plurality of passageways (26) is defined in the floor for receiving a corresponding number of electrical contacts (3) therein. Each contact includes an arm (30) extending beyond the floor for contacting with corresponding contacting pad of the LGP (4). All the arms extend in a plurality of rows, parallel to one diagonal of the floor, and the arms in a same row are arranged side by side. Each passage includes an upper receiving portion extending into an adjacent passage in the same line, therefore, the passages in the same line are stringed, and a continuous support member is formed between two rows of stringed passages.

A vacuum pick up cap (10) for use with an electrical connector (20) includes a body portion (12) to be sucked by a vacuum suction nozzle and a number of legs (13) retained to the electrical connector. The body portion has an upper and a lower faces (120), (121) each having a central recess (122), and a number of peripheral recesses (123) surrounding the central recess, the recesses being spaced from each other. The body portion is substantially reduced in thickness due to the presence of the recesses.

A ZIF socket (2) comprises a base (20) defining a bottom half channel (200) and a cover (22) defining an upper half channel (220) wherein the bottom half channel joins with the upper half channel to form a full channel enclosing a lever (24) of the socket having a cam shaft (242) and a handle (240). A retention means (205) is fixed on the rear portion of the base, a resilient arm extends forwardly from a top portion of the retention means and defines a recess (209) thereon. The recess (209) can keep the handle positioned on one side of the socket at a vertical position with regard to the base.

A socket connector (1) includes a base (10) defining an array of terminal cells (111), a number of conductive contacts (30) received in the respective terminal cells, a cover (20) slidably mounted on the base and a driving device (40) sandwiched between the cover and the base for driving the cover to move relative to the base. The cover has a supporting surface (211) for supporting a CPU (5) and defines an array of pin holes (213) corresponding to the terminal cells for insertion of pins (51) of the CPU therethrough. A standoff is formed on each of peripheral edges of the supporting surface, and a number of small-dimensioned supporting posts (222) and large-dimensioned supporting posts (223) are formed on the supporting surface within the outline positions of the standoffs for supporting the CPU mounted on the socket connector. The standoff and the supporting posts have the same height.

A burn-in socket includes a base, a sliding plate mounted to the base and having a number of pin holes, a number of contacts secured to the base and an actuator mounted on the base. The contacts each comprise a base portion and a pair of arms received in the pin holes of the sliding plate. The actuator includes a frame and a number of actuating portion for driving the sliding plate to move in a transversal direction. The sliding plate includes a number of projections adjacent to contacts. Each projection and the pair of arms of an adjacent contact together define a receiving space and located at three sides of the receiving space, respectively.

An electrical connector (20) mounted on a substrate (20b) defining holes (22) includes a base (30) and first and second terminals (62, 84) attached to the base. Each terminal has a retention portion (622) and a pair of curved arms (624, 626) extending from opposite ends of the retention portion. The pair of curved arms are respectively formed with upper and lower contact portions (623, 625). Each terminal has a securing portion (842) and upper and lower mating portions (844, 848) extending from opposite ends of the securing portion. Certain second terminals each have a bent portion (846) to make the pitch between the lower mating portions of two adjacent second terminals larger than that between the upper contact portions of two adjacent first terminals, thereby conveniently and safely drilling the holes of the substrate in which the lower mating portions are secured.

A land grid array (LGA) socket is adapted to receive an IC module (40) and mounted on a PCB (50). The socket (1) includes an insulative housing (30) having a plurality of passageways (302) and a plurality of electrical terminals (10) received in the passageways. Each of the terminals includes a retention portion (12), a pressing arm (16) bent slantwise and extending upwardly from an end of the retention portion, and a contacting arm (18) bent slantwise and extending downwardly from another end of the retention portion. At least one connecting plate (14) connects the pressing arm and the contacting arm, the connecting plate disconnects the retention portion, thereby decreasing impedance of the terminal.
