Abstract: An electrical contact (1) includes a retention portion (10) and a cantilever (12) extending upwardly from the retention portion. The cantilever includes a first extending portion (121) and a second extending portion (120) bent vertically from the first extending portion. A top elevation projection of the second extending portion relative to the retention portion forms an acute angle therebetween. The first and second extending portions are both resiliently deformable. Thus the contact attains good resilient characteristics. Moreover, a contact strip (16) for the contact comprises an elongate carrier strip (160) and a plurality of strip contacts (1?) attached to the carrier strip. Each strip contact includes a cantilever (12?) having a second extending portion (120?). The second extending portion is orientated at an acute angle relative to a longitudinal axis of the carrier strip. Thus gaps between two adjacent strip contacts are small, which reduces production costs of the contact.

Abstract: A socket (20) includes a dielectric housing (30) and conductive terminals (40) secured in the housing. The housing defines upper and lower surface (322, 324) and a number of cells (320). Each terminal has a retention body (42) secured in a corresponding cell. The body has an upper end (422) flushed with the upper mating surface and a lower end (424) projected beyond the lower surface. Upper and lower protrusions (321, 323) extend from the upper and lower mating surfaces of the housing respectively, for supporting conductive pads (51, 53) of mating electrical devices. The lower protrusions project beyond the lower surface a vertical distance farer than that of the lower end. Thereby the pads can be prevented from electrically engaging the bodies when the mating electrical devices mate with the socket.

Abstract: An LGA connector assembly (1) includes an LGA connector (2) and a generally rectangular pick-up cap (3) mounted onto the connector. The connector defines a number of passageways (212) for receiving a corresponding number of contacts (22). The pick-up cap has a first surface (300) engaged with a vacuum suction device and a second surface (301) opposite to the first surface, a plurality of vents (302, 303) disposed therethrough, and a plurality of recesses (310) formed adjacent to the vents on the second surface. The recess with blind cavity configuration and the vent are formed a gap-depth air vent therebetween along a direction of perpendicular to the pick-up cap, thereby permitting heated air to easily and uniformly flow therethrough during mounting the connector assembly onto a circuit board by SMT.

Abstract: An electrical contact (1) for electrically interconnecting two electrical components (3, 4) includes an inverted “U”-shaped retention portion (11), a substantially “U”-shaped extending portion extending (12) from the retention portion. The extending portion defines first and second mating portions (122, 121) respectively at uppermost and lowermost sections thereof, for engaging with the electrical components. The extending portion forms an engaging portion (125) to mate with the retention portion. Thus two parallel electrical paths are formed between the first and second mating portions when the contact electrically mates with the two electrical components. As a result, impedance of the contact is decreased and good resilient characteristics of the contact are attained.

Abstract: An electrical connector includes a base (2?), a metal clip (3) pivotably engaged on the base, and a lever (4) for fastening the clip onto the base. A floor (232?) is defined in a middle of the base. A rectangular raised support area (23?) is provided around a periphery of the floor. The support area defines four inner side walls (231?). The side walls and the floor cooperatively define a substantially rectangular cavity (230?) therebetween. One of the side walls defines a pair of protrusions (2310?) protruding towards the cavity, wherein the two protrusions are coplanar with each other. The other side walls define a protrusion thereof respectively. Therefore, a first benchmark is obtained by a line joining the pair of protrusions on the side wall, and a second benchmark is determined by a line passing the protrusion on the adjacent and perpendicular side wall, perpendicular to the first benchmark.

In use, the pick up cap is mounted between the clip and the housing, therefore, it is close to the contacts and covers nearly all the exposed contacts, thereby providing the protection of the contacts.

Abstract: A socket connector (1) includes an insulative housing (2) and a plurality of terminals (7) received in the housing. The housing defines a plurality of passageways (24) for accommodating the corresponding terminals. Each passageway forms a step (248) therein for dividing the passageway into a receiving channel (246) and an interfering channel (242). Each terminal defines a fastening portion (70) for securing the terminal in the passageway and the fastening portion forms a pair of straight interfering sides (710). The distance from one of two straight interfering sides to the other is greater than the width of the interfering channel. When the terminal is installed into the housing, the terminal is firmly positioned in corresponding passageway by virtue of the interfering force between the two straight interfering sides and the interfering channel.
