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).

US Classification:

439157

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). Such ejector (50) has a hook section (54) for pushing the bottom edge portion of the daughter board (100) upwardly and releasing the daughter board (100) from the connector (1), accordingly. The housing (10) of the connector (1) itself has a closed type opening on the top in the lengthwise direction which efficiently aligns and orients the daughter board (100) in the lengthwise direction for avoiding any misalignment of the daughter board (100) during the insertion process.

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. The housing (10) further comprises a cavity (14) defined by walls of the housing (10) for receiving the rear portion of the inserted memory card (100) therein, and an opening (29), which is generally positioned about the centerline of the housing (10), recessed through the front portions of the top and bottom walls (15, 16) of the housing (10) for facilitating manually grasping the rear portion of the corresponding memory card (100) during insertion or withdrawal of such memory card (100) with regard to the computer case.

439326

Abstract:

A connector assembly for use with a unitary daughter board having different contact pitch arrangements on the lower edge portion, includes two different contact pitch arrangement connectors lengthwise aligned and juxtaposed with each other for commonly receiving the lower edge portion of the daughter board. The connector of the high density contact arrangement includes an outer end wall having a recess at the top for functioning as a pivoting point of the rotative movement of the daughter board without interference thereof. A middle partition wall of the same connector has the curved surface thereof in conformity with the rotation path of the daughter board.

US Classification:

439326

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. A metal latch (40) including a generally U-shaped body (46) and a retention blade (44) separately and respectively independently extend from a main base (42) so that the latch (40) can be reliably securely retained horizontally within each arm (20) of the housing (10) wherein the hook (54) of the latch (40) upwardly extends out of the platform (22) for engagement with the daughter board (100) thereon, and the lever (56) of the latch (40) extends forwardly out of the front end surface (21) of the arm (20) for easy manually operative deflection.
