  • Patent number: 6827585
    Abstract: An electrical connector (1) for connecting a land grid array (LGA) chip with a printed circuit board (PCB) includes a housing (10), and terminals (110) received in passageways (101) of the housing. The housing has a base (100) and sidewalls (102, 104), the base and the sidewalls cooperatively defining a space therebetween for retaining the LGA chip. Two sidewalls each define recesses (1021), thereby forming projections (1020). When terminals are installed near the projections, a carrier strip (11) connecting the terminals is bent so that connecting sections (111) of the carrier strip are received in corresponding recesses. The connecting sections are cut off, and the carrier strip is removed. The recesses enable the carrier strip to be manipulated so that sufficient space is made available for cutting off of the connecting sections without interfering with the sidewall. The projections provide precise fitting positioning of the LGA chip in the space.

  • Patent number: 6632101
    Abstract: An electrical socket connector (1) comprises a base (2), a cover (3), and a locker means (5). The base has a plurality of contact passageways (21) defined from an upper surface (27) to a bottom surface (28) thereof and at least a first protruding portion (24) on one side thereof. The first protruding portion has a first receiving slot (26) defined therein. A plurality of contacts (4) are received in the passageways of the base. The cover is moveably mounted on an upper surface of the base and defines a plurality of receiving holes (31) in alignment with the contact passageways adapted to receive corresponding pins of an IC module to extend therethrough into the passageways. The locker means comprises a stopper portion (53) and a locker portion (52) extending from the stopper portion.

  • Patent number: 6560113
    Abstract: An electronic device assembly includes a PCB (20), a socket (26) mounted on the PCB, a CPU (22) connected with the socket, a thermal module (30) in thermal contact with the CPU, and a back plate (10) attached to an underside of the PCB opposite the CPU. The back plate includes a pair of recessed portions (14), and a protruding portion (12) between the recessed portions. The protruding portion is configured to abut against the PCB and thereby prevent deformation of the PCB. A plurality of bolts (50) extends through the recessed portions of the back plate, the PCB and the thermal module, and respectively threadedly engages with a plurality of nuts (40). The electronic device assembly is thereby fixed together.
