Abstract: A DIMM connector (10) includes an elongated insulative housing (12) with a central slot (14) for receiving a DIMM (100) therein wherein two rows of contacts are positioned by two sides of the slot (14). A pair of cavities (22) are provided at two opposite ends of the housing (12) for receiving a pair of corresponding latch/eject members (70) therein. Rotation restriction means for limiting the rotation of the latch/eject member (70) with regard to the housing (12), includes a first engagement surface (85) provided on the eject portion (78) of the latch/eject member (70) and a second engagement surface (42) provided on the housing (12). A reinforcement wall (32) is transversely provided of the housing (12) and substantially between two side walls (24), but does not obstruct the assembling of the latch/eject member (70) into the cavity (22) in the housing (12).

Abstract: Magnetic cards are provided with unique card signatures which include a number of bits, some of which have intermediate magnetic levels. As a result a card reader allocates randomly either a one or a zero to the intermediate level bits. The random allocation provides a test for the genuineness of the card. The intermediate level bits are formed as a result of inherent inconsistencies in the characteristic of a normal magnetic stripe along its length. It is not possible therefore to readily, if at all, reproduce patterns of intermediate level bits in a duplicate because the stripe on the duplicate will have differently arranged inconsistencies along its length.

Abstract: A female connector (30) comprises an elongated housing (32) and two separate blades (34, 36). The housing (32) includes one power region (40) and one signal region (50) spaced from each other by a space (90) therebetween. The power region (40) includes a plurality of first passageways (42) for receiving a corresponding number of first contact (60) therein. The signal region (50) includes a plurality of second passageways (52) for receiving a corresponding number of second contacts (70) therein. The opening (41) of the passageway (42) has an expanded curved contour (48) on two sides for allowance of lateral deviation of an inserted male contact, and the first contacts (60) includes a pair of arms (66) arranged to face each other in a vertical direction for being adapted to receive the deviated inserted male contact of a complementary connector (14).

Abstract: A socket connector (1) includes an insulative housing (10) having a central slot (12) therein along its lengthwise direction for receiving a lower edge portion (101) of a daughter board (100) therein. A plurality of passageways (14, 16) are arranged staggered on two sides along the slot (12) for receiving the upper row contacts (60) and the lower row contacts (80) therein for electrical engagement with the corresponding circuit traces (108) on two sides of the daughter board (100). Two arms (20) respectively extend forwardly from two ends of the housing (10) and each arm (20) thereon forms a platform (22) for allowing the inserted daughter board (100) to sit thereon.

Abstract: A housing (10) incorporating a memory card connector (40) positioned in the computer for use with a memory card (100), is independently mounted on the backpanel (12) of the computer case and installed in the exterior of the computer case. The housing (10) is aligned with the inside corresponding memory card connector (40) by means of two opposite supporting arms (18) of the housing (10) being generally in alignment with the grooves (47) in the corresponding rails (44) of the memory card connector (40), respectively.

Abstract: A card edge socket connector (1) includes an insulative elongated housing (10) having a plurality of contact slots (14) side by side vertically extending therethrough. A plurality of contacts (90) are received within the corresponding contact slots (14), respectively. A central board slot (12) extends in the housing (10) in the lengthwise direction for reception of the bottom edge portion of daughter board (100) inserted therein whereby the contacts (90) are electrically engaged with the traces on the bottom edge portion of the daughter board (100). An ejector (50) is pivotally positioned in a cavity (30) at one end of the housing (10) and a pair of separate latches (70) are positioned adjacent such ejector (50) but segregative and spaced therefrom by substantially a portion of the insulative housing (10) for latchably sandwiching and engaging within a retaining (92) hole of the daughter board (100) when the daughter board (100) is received in the board slot (12) in the connector housing (10).
