Abstract: A system (10) for interconnecting two modules (100, 100') to the CPU chip, includes two opposite connectors (12, 14) in a head-to-head arrangement. The traces (200) each of which connects the two corresponding contacts 28/30 and 30'/28' each being located in the same position of the corresponding connector (12, 14), are generally arranged in a parallel relationship. One (12) of the connectors (12, 14) is substantially a standard one which meets the requirements defined in the general specification. The other (14) of the connectors (12, 14) is generally, but not exactly, of a mirror image with regard to the first one (12), wherein the positions of the two-row contacts (28'/30') with regard to the housing (16') along the lengthwise direction of the second connector (14) are arranged in an opposite relationship with regard to those in the first connector (12).

Abstract: A connector (10) includes a housing (12) defining a plurality of passageways (16) for receiving a corresponding number of contacts therein. The housing (12) further includes three projection bars (20) extending rearward from a rear surface (18) of the housing (12) for protectively accommodating the corresponding plural contact tails therebetween. A mounting device (22) includes a pair of individual mounting ears (24, 24') which are relatively closely side by side positioned within two juxtaposed slots (38, 38') of the housing (12) wherein each mounting ear (24, 24') has a retention section (28, 28') interferentially embedded within a retention slit (44, 44') for fastening the mounting ear (24, 24') to the housing (12), and an L-shaped mounting section (32, 32') closely beside one side surface (36, 36') of the bar (20).

Abstract: A socket (10) for retainably receiving a module (11) therein, includes an insulative housing (12) having a plurality of passageways (16) extending therethrough in a front-to-end direction for receiving a corresponding number of contacts (18) therein for engagement with the corresponding circuit pads on the module.

Abstract: A connector assembly (10) includes a lower housing (14) and an upper housing (12) each generally including the basic structure of the typical SO DIMM connector housing (16, 16'). Each housing (14, 12) defines two rows of passageways (20, 20') on two sides of the central slot (18, 18') in which the corresponding module (100) is received. A plurality of contacts (40, 42, 50, 52) are received within the corresponding passageways (20, 20') wherein the tail of each contact (40, 42, 50, 52) extends downward to engage the corresponding circuit on the PC board (100) on which the connector assembly (10) is mounted.

Abstract: A card edge connector (10) includes an insulative housing (12) defining an elongated channel (14) for receiving a card therein. A pair of tower sections (22) are portioned on two opposite ends of the housing (12), and each defines a cavity for receiving therein an ejector (28) wherein each ejector (28) has a main body (36) with an elongated slots (42) extending along almost the whole lengthwise dimension of the main body (36) except the handle (40), and substantially therethrough in a lateral direction thereof so as to provide a good resiliency of the main body (36). A pair of retention protrusions (32) are respectively positioned on two sides of the main body (36) wherein the retention protrusion generally positioned about the middle point of the slot (42), is large enough to resist wear so that the ejector (28) can be easily rotatably moved with regard to the housing (12) while still keeping good retention function with the housing (12) when it is in a vertical position.

Abstract: A card edge connector (10) includes an insulative housing (12) defining a central slot (14) for receiving a card (100) therein. A cavity section (18) is provided at one end of the housing (12) with an alignment end wall (40) for aligning the inserted card (100) in a lengthwise direction. An ejector (20) is rotatably received within the cavity section (18) by means of a spindle (32), a center of which is relatively closer to an inner surface (42) of the ejector (20), wherein the inner surface (42) of the ejector (20) includes at least a first plane-like section (44) generally coplanar with the outer surface (45) of the end wall (40), a second arc-like section (46) generally conformable with the periphery of the spindle (32), and a third plane-like section (48) spaced from the outer surface (25) of the end wall (40) in a substantial distance, when such ejector (20) is in a vertical locked position with regard to the housing (12).

Abstract: A card edge connector (10) includes an insulative elongated housing (12) having a central slot (14) for receiving the corresponding card (100) and having at least one ejector (20) at its longitudinal end. The ejector (20) comprises a kicker (32) at the bottom for engagement with the bottom edge of the card (100) received within the connector (10). The ejector (20) further includes a locking projection (30) horizontally and inwardly projecting toward the central slot (14) for engagement within a notch (104) of the inserted card (100). A pair of retention bars (22) or restraint devices for limiting lateral movement of the inserted card with regard to housing (12), vertically extend by two sides of the central slot (14) adjacent the ejector (20). The pair of retention bars (22) extend over the locking projection (30) of the ejector (20) in the vertical direction for substantially protectively covering the locking projection (30) in the vertical and/or horizontal direction.

Abstract: A card edge connector (10) includes an elongated housing (12) defining a central slot (14) along its lengthwise direction for receiving a card (100) therein. A plurality of passageways (16) are formed in the housing (12) by two sides of the slot (14). Two cavities (18) are formed at two opposite ends of the housing (12) for receiving a pair of corresponding ejectors (20) therein, respectively. A pair of retention bars (34) are positioned adjacent each end of the housing (12) and respectively on two sides of the slot (14). Each ejector (20) includes a main body (22) which is substantially higher than the adjacent retention bars (34). A pair of stopper blocks (32) are formed on two side surfaces (28) of the main body (22) for engagement with the corresponding retention bars (34), respectively, when the ejector (20) is in the vertical position.

Abstract: A card edge connector (10) includes an insulative housing (12) having a central lengthwise slot (14) for receiving a module (100) therein and a plurality of passageways (16) disposed by two sides of the slot (14) for receiving a corresponding number of contacts therein for mechanical and electrical engagement with the circuit pads printed on the bottom edge region of the module (100). A pair of guidable retention bars (18) integrally extend upward adjacent either end of the housing (12) wherein each guidable retention bar (18) includes a retention block (20) at the top.
