摘要： An electrical connector (1) for connecting a land grid array (LGA) chip with a printed circuit board (PCB) includes a housing (10), and terminals (11) received in passageways (102) of the housing. The housing defines a base (100) and four sidewalls (12), the base and the sidewalls cooperatively defining a space therebetween for receiving the LGA chip. The base has a multiplicity of passageways along a length thereof, for receiving the corresponding terminals therein. Two adjacent sidewalls each define a resilient beam (13) with an incline surface and joining the sidewall at two ends. A space (15) is defined between the beam and the sidewall. When the LGA chip is placed on the base, the two resilient beams can resiliently act on the chip to ensure reliable engagement between the LGA chip and the connector.

摘要： A ball grid array (BGA) socket (5) includes an insulative member (52), a number of conductive contacts (54) attached to the insulative member in an array and a number of solder balls (56) respectively attached to corresponding conductive contacts and arranged in an array in accordance with the conductive contacts. The insulative member provides a number of stand-offs (60) on the mounting surface thereof and located in the array of the solder balls. When the BGA socket is located on a printed circuit board (PCB, 80) and heated, the solder balls become soft or melted and the insulative member sinks until the stand-offs bear against the PCB. Since the stand-offs are located in the array of the solder balls, the solder balls are not spaced from the PCB too close or too far, therefore the solder balls close a center of the connector may not be disconnected from corresponding solder pads or interconnect with the adjacent solder balls.

摘要： A ZIF socket (1) on which a CPU (2) is mounted. The CPU (2) has a plurality of pins (21) extending through a cover (11) into a base (12) of the socket for electrically engaging with contacts (110) received in the base. The cover defines two slots (1112) in two opposite sides of a top face thereof. The slots are located below two side edges of the CPU, whereby there is more space for a user's fingers to grip the CPU to pull it away from the socket in order to replace CPU with another one.

摘要： A contact (10) for a ZIF PGA socket (20) includes a horizontal single-beam contact portion (12) and an elongated mounting portion (11) depending from the contact portion. The mounting portion includes a fixing portion (16) for fixing to the socket, a leg (19) depending from the fixing portion for extending through the socket and electrically communicating with a circuit board, and a neck (14) integrally connecting the contact portion and the fixing portion. The neck is substantially narrower than the fixing portion and the contact portion, thus allowing the contact portion to twist about a central vertical axis of the contact and to be displaced relative to the fixing portion. The contact portion can thereby rotatably contact and resiliently press against a corresponding pin (30) of a mating PGA device.

摘要： A socket connector includes a rectangular base plate adapted to be positioned on a circuit board and retaining an electronic device, such as an integrated circuit, thereon for establishing electrical connection between the electronic device and the circuit board by means of contacts retained therein. Bumps are formed on the base plate for engaging with notches defined in the electronic device to precisely positioning the electronic device with respect to the base plate. A retention module includes a frame having four wall segments defining an interior space therebetween for receiving the base plate. A pair of sideways projections is formed on one wall segment with aligned holes defined therein for receiving pivots of a resilient clip thereby making the clip movable between an open position where the base plate is exposed for receiving the electronic device and a closed position where the clip resiliently engages with the electronic device thereby securing the electronic device to the base plate. A pair of sideways projections is formed on an opposite wall segment each having a barb for engaging an opening defined in a corresponding resilient arm of the clip for fixing the clip at the closed position. Each sideways projection forms a bifurcated board lock for being received in a hole defined in the circuit board. A pin is inserted into a bore defined in each sideways projection to expand the board lock thereby securely fixing the socket connector to the circuit board.

摘要： A contact strip includes a number of conductive contacts (4), a contact carrier (5) and a corresponding number of links (6) connecting corresponding contacts to the contact carrier. Each contact includes a contact portion (42) and a soldering portion (43) opposite the contact portion for attaching a solder ball for soldering to a printed circuit board. The contact portion is plated with gold using a molten gold plating liquid for enhancing electrical/mechanical characteristics of the contact portion. Each link defines a longitudinal slot (61) for obstructing a wicking path from the contact to the contact carrier. Furthermore, an elongate opening (52) is defined in the contact carrier above and perpendicular to a corresponding slot to further prevent the plating liquid from wicking up to the contact carrier, thereby preventing loss of the expensive plating liquid and reducing the cost of the contact.
