Abstract: An expansion slot mounted on a motherboard of a microcomputer for electrically coupling to an inserted adapter card is disclosed. Inserting the adapter card into the expansion slot will flex a flexible member until a protrusion enters into a hole of the adapter card for fastening. Flexing a latch away from a second stop member will disengage the protrusion from the hole wherein the flexing of the latch is defined by contacting a bent member with a first stop member. Flexing the latch toward the second stop member will be stopped when the protrusion contacts the second stop member.

Abstract: A device for fastening a card on the motherboard of a computer is provided. In one embodiment, the device comprises an elongated, upright snapping assembly and a substantially U-shaped seat assembly secured thereon. Fastening a first end of the card at a connector on the motherboard, placing the second end thereof in the fastening device by pressing a latch member, positioning two risers in two slits of the second end, and releasing the latch member will cause two latch elements to exert a resilient force on the second end of the card for fastening.

Abstract: Disclosed is an improved structure for an extension card connector comprising a connector body with a central fissure formed for interleaving with an extension card therein; two pusher members disposed in both sides of said connector body, each said being provided with a short cylindrical stem, and a narrow slot formed at the middle of lower half portion thereof, the narrow slot contains a cylindrical post aligned to the stem with respect to a common central axis; two accommodation slots formed respectively at both ends of the connector body for accommodating the two pusher members therein, a trap is formed respectively at each the wall surface of each accommodation slot for capturing the two stems therein and prohibiting their vertical upward and horizontal excursion; and two sustaining members provided for the two accommodation slots at the center thereof which are able to be inserted into the two narrow slots, and an positioning slot is provided at the top end thereof for contacting with the bottom of each

Abstract: This invention relates to an edge card connector, the edge card connector being composed of a connector, an edge card and one or more turning arms. The connector has an inserting groove for installing the edge card, the turning arm being installed at one or two sides of the connector. The turning arm has a pushing part and an arc seat, the pushing part can push out the edge card from the inserting groove when the turning arm is rotated upwardly. The arc seat can slide into the arc groove of the connector to allow the turning arm to rotate within a setting angle around the arc seat. At the side of the connector is an elastic vertical plate having a stopping face formed at its bottom. The arc seat is situated under the stopping face, such that, the end of vertical plate is pressed inwardly by the arc seat when inserting the turning arm into the arc groove.

Abstract: A quantitative dispenser including a cylindrical body with a bottom. A separator plate is engaged in an inner annular slot on the top of the cylindrical body. The separator plate has a central engaging hole and a flow-through opening. A cover is engaged over the outer periphery of said body. The cover has an outlet with a sealing cap and engages the separator plate. A scale divider has a sleeve part and a wing part. The sleeve part is slipped on a hollow engaging shaft and the wing part is able to be fixed as a way to form a measuring scale on the inner periphery of the cover. A scale is provided on an outer surface of said cover. The powdered milk stored in the body can pass through the flow-through opening on the periphery of the separator plate into a measuring space. The powder is then dispensed through an outlet in the cover.
