Abstract: A memory card connector includes a pair of guide frames and a connector head. The ejection mechanism of the memory card connector comprises a top cover plate that has a pair of arms each extending from one end thereof for engaging one corresponding pair of guide frames. The top cover plate has a pair of guide rings each located at one end thereof and a guide sliding space formed between the guide rings. A rocker lever has a pivotal hole approximately at the center, and a guide containing opening is formed at one end. A push-out plate has a pair of sliding recessions and a pair of card pushing edges, wherein each pushing edge is located adjacent one end thereof and a guide rod formed between the sliding recession. A push rod has a rocker lever engaging slot at one end thereof. The pivotal hole of the rocker lever receives one of the guide ring shaft formed by the guide rings. The guide containing opening receives the guide rod of the push-out plate.

Abstract: A grounding strip for a memory card connector is disclosed to provide the electrical grounding of the memory card inserted. The memory card connector comprises a guide frame having a pair of guiding slots. Each of the guiding slots has formed therein a pair of notches and a receiving slot. The grounding strip comprises a substantially elongated body. A curved contact portion is formed approximate one end of the elongated body that arises generally above the surface of the elongated body. An end portion is formed at the remote end beyond the contact portion of the elongated body. A first pair of bent portions are respectively located at the opposing sides of the elongated body and extending away from the surface of the elongated body, and each of the first bent portions has formed thereon a latching means. When the grounding strip is assembled to the designated location on the guide frame of the memory card connector, the end portion would be received in the receiving slot of the guiding slot.

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 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).

Abstract: A ZIF PGA socket assembly (1) includes a base housing (10) having a top surface (12) and a plurality of elongated cavities (14), and a corresponding number of contacts (100) each having a pair of elongated spaced arms (108, 110) disposed in respective cavities (14). A sliding plate (70) which designedly slidably moves on the top surface (12) of the base housing (10), has a plurality of orifices (74) therethrough in registration with the corresponding cavities (14) in the base housing (10) to not only admit conductive pins from a PGA component into the cavities (14) but also bias one arm (108) of each contact (100) to form an enlarged space between such pair of arms (108, 110) for zero insertion force for conductive pins of the PGA component when the sliding plate (70) is in an operation position. A cover (50) is mounted on the top of the sliding plate (70) for cooperation with the base housing ( 10) to sandwich the sliding plate (70) therebetween.

Abstract: A contact (10) comprising a planar conductor having an elongated base (12) with two opposite spaced ends (14, 16). A pair of contact beams (18, 20) respectively extend from a common position spaced from a first end (14) in a distance of generally one third of the whole length of the base (12). A high beam (18) of such pair of contact beams (18, 20) generally extends upward and slightly inclined to the first end. A generally U-shaped section (22) is positioned at the top of the high beam (18) wherein such U-shaped section (22) is dimensioned to be generally a half of the vertical dimension of the whole high beam (18). A low beam (20) of such pair of contact beams (18, 20) generally extends horizontally to the second end (16) of the base (12). A generally C-shaped section (24) is backward positioned at the free end of the low beam (20) wherein such C-shaped section (24) is dimensioned to be generally a half of the horizontal dimension of the whole low beam (20).

Abstract: An electrical socket (10) includes an insulative housing (12) with cavities (14) extending vertically therethrough and a plurality of contacts (30) retained in the cavities (14), respectively. An engagement bar (22) is positioned proximate the upper open end of each cavity (14) so that when the contact is assembled in each corresponding cavity (14), the front portions of the spring arms (40) of each contact (30) can move along a guiding pin (62), which is inserted into the cavity (14) from the top open end temporally only for the sake of assembling of the contacts (30) within the socket (10), and be deflected outwardly so that the tips (44') of the spring arms (40) of the contact (30) can pass the engagement bar (22) and be positioned by the sides of the engagement bar (22).
