摘要:
A land grid array (LGA) 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 the housing. The housing defines a base (100) and four sidewalls (12, 13, 14, 15), the base and the sidewalls cooperatively defining a central receiving cavity (101) therebetween for receiving the LGA chip. The base has a number of passageways (102) along a length thereof, for receiving the corresponding terminals therein. Two adjacent sidewalls each define a resilient arm (120, 130) extending into the central cavity from an inner portion thereof. The other two adjacent sidewalls each define two securing blocks (140, 150) on an inner portion thereof. When the LGA chip is placed on the base, the resilient arms and the securing blocks can act on the LGA chip and cooperatively fix the LGA chip in the central cavity.

An electrical connector (1) for interconnecting an LGA chip (60) with a PCB includes an dielectric housing (10) defining a number of terminal passageways (16) with a plurality of electrical contacts (12) accommodated therein, a metal reinforcement (20) enclosing the housing (10) partly, a loading plate (40) pivotally mounted to an end of the reinforcement (20), and an actuator member (30) attached to an opposite end of the reinforcement (20) for engaging with the loading plate (40). The loading plate (40) defines a pair of pressing portions (43) to press the chip (60) against the connector (1). The pressing portion (43) defines some flexible materials (431) on the bottom surface (430) toward the housing (10) for protecting the chip (60) from being scraped by the loading plate (40).

A socket connector includes a housing positioned on a circuit board and movably supporting a cover. Cells are defined in the housing for retaining dual-beam terminals. The cover carries a central processing unit module having pin legs extending through holes defined in the cover and projecting into the cells of the housing. The cover is movable in a moving direction to bring the pin legs into engagement with the terminals. Each terminal includes a base section retained in each cell and a tail extending and beyond the housing for being soldered to the circuit board. Two beams extend from the base section, substantially opposite to the tail. Each beam forms a spring arm. The spring arms are opposite to and spaced from each other for engaging the corresponding pin leg therebetween. The beams are symmetric with respect to an imaginary plane that is normal to the base section and coincident with the moving direction. Each beam has a major surface angularly offset from the imaginary plane and thus forming a first included angle with the imaginary plane. The major surface also forms a second included angle with the base section. The included angles are smaller than 90 degrees and greater than 0 degree. Preferably, the included angles are 45 degrees. The angularly offset configuration of the beams allows easy adjustment of the space between the spring arms and thus adjustment of the performance parameters of the terminals.

A mobile socket (1) comprises a base (10), a cover (20), a plurality of contacts (30) mounted in the base, a rotatable cam actuator (40) for actuating the cover to slide on the base, a protecting mechanism (50) and a washer (60). The protecting mechanism comprises a cover plate (51) in the cover and a bottom plate (52) in the base. The cover plate defines an elongated slot (512). A pair of opposite cam stoppers (515) extends upwardly from one side of the slot. The cam actuator has a protrusion (45) abutting against one of the cam stoppers during rotation.

An LGP connector comprises an insulative housing and a plurality of contacts. The housing defines a plurality of passageway sections for receiving the contacts therein. Each contact includes a soldering base for soldering the contact to a printed circuit board and an upper contact beam for electrically connecting the contact with an LGP chip, thereby electrically connecting the chip with the printed circuit board. Each contact comprises a pair of anti-rotation tabs extending from an end of the soldering base, and each passageway section transversely defines an anti-rotation cavity in a bottom face thereof and at a first side wall thereof for retaining the anti-rotation tabs of the contact.

A scissors-like handle tool manipulates a ZIF socket having a cover slidably engaged with a bottom, between a loosened status and a tightened status. The handle tool comprises a first lever arm pivotably connected to a second lever arm. The handle tool is operated by encountering two lower ends of the first and second lever arms with two movable sides of the socket via a pivot operation of the handle tool thereby moving the cover of the ZIF socket along the bottom.

A contact comprises a plate, a positioning section connected to the plate via a first flexible neck and adapted to be mounted by an external solder ball, a contacting section located above and connected to the positioning section via a second flexible neck. The first flexible neck is deformable to absorb a tension originated from the plate. The second flexible neck is deformable to force the contacting section to abut against an external electrical device when the external electrical device urges the contacting section to electrically connect to the solder ball via the contact.

An electrical connector assembly for connecting a chipset to a printed circuit board comprises a dielectric housing having a number of terminal-receiving passageways defined between a top mating face and a bottom terminating face thereof. Two connecting protrusions are respectively formed on opposite sides of the housing. A number of terminals are received in the passageways of the housing. Each terminal has a contact portion and a tail portion extending from the contact portion. A fastening piece is attached to the housing, and includes a body and two legs extending substantially perpendicular from opposite ends of the body. Each leg defines a mating groove on an inner face thereof for mating with the corresponding connecting protrusion of the housing. When the fastening piece is mounted to the housing, the chipset is securely sandwiched between the fastening piece and the housing, and when the fastening piece is removed from the housing, the chipset can be easily detached from the housing.
摘要:
A socket connector includes a rectangular base defining an array of slots arranged in rows and columns parallel to edges thereof. The slots receive and retain contact elements therein. A rectangular cover is movably supported on the base and defines holes therein corresponding to the slots for receiving pins of a central processing unit (CPU). The base has lugs formed on two diagonal corners thereof each forming a wall substantially normal to the diagonal direction. The cover forms a straight edge at a comer corresponding to each lug of the base. A triangular notch is formed in each wall having a first side inclined with respect to the diagonal direction and a second side substantially parallel to the diagonal direction. The notch is capable of receiving a screwdriver therein and allows the screwdriver to rotate. The rotation of the screwdriver causes an edge thereof to partially project beyond the wall and drivingly engages with the corresponding straight edge of the cover for moving the cover with respect to the base thereby driving the pins of the CPU to engage with the contact elements.
