摘要： A heat sink assembly includes a CPU mounted on a socket connector (1) and a retention module (5). The retention module comprises a pair of metal frames (50), a pair of retaining claps (56) and a pair of stop bars (54) assembled together with the metal frames. Each frame defines a bottom wall (51), a first side wall (52) and a pair of second side walls (54). Each retaining clip has a hook (56c) formed at a top of the retaining clip for hooking a corresponding stop bar, and a clamping portion (56e) formed at a bottom of the retaining clip. The clamping portion and a free end of the hook together clamp a side portion (41a) of a heat sink assembled to the socket connector.

摘要： An electrical socket for interconnecting an LGA chip with a PCB includes an insulative housing (2) and a multiplicity of terminals (1). The housing includes a plurality of passageways (26) extending therethrough for engagingly accommodating corresponding terminals. Each terminal includes a locating plate (10) arranged in rows, and a mating beam (12) connected to the locating plate and extending along the corresponding row. The terminals and the mating beams are arranged so that a projection A of each mating beam along the corresponding row is longer than a distance B between each two adjacent locating plates of two adjacent terminals arranged in the same row. Accordingly, when the mating beams are engaged with electrodes of the LGA chip, the mating beams are long enough to provide excellent resilient deflection characteristics, thereby ensuring good mechanical and electrical connection between the mating beams and the electrodes.

摘要： A ZIF PGA socket includes a first housing and at least one second housing slidably received in the first housing. The at least one second housing defines a plurality of passageways for retaining corresponding number of contacts therein. Each contact has a first portion fixed in the passageway, a second portion fixed to a printed circuit board and a third portion deformably connected between the first portion and the second portion. When the at least one second housing is moved with respect to the printed circuit board, the third portion of the contact deforms to absorb stress to the second portion of the contact.

摘要： A driving mechanism is used for a socket which comprises a cover movably mounted on a base. The driving mechanism comprises a first reception space defined in the cover, a second reception space defined in the base and communicating with the first reception space, a driving cam having an upper portion rotatably retained in the first reception space of the cover and a lower portion rotatably and movably retained in the second reception space of the base. The upper portion of the driving cam is operative to rotate the lower portion of the driving cam in the second reception space which is subjected to reactive force from inner wall of the second reception space so that as the cam rotates it also moves linearly, thereby forcing the upper portion of the driving cam to pulling the cover to translate on the base.
