Abstract: A retention mechanism for an electronic assembly which has a substrate and a heat sink. The retention mechanism includes a substrate slot that receives the substrate and a heat sink slot that receives the heat sink. There may be two retention mechanisms that are attached to a printed circuit board adjacent to an electrical connector. There may be two heat sink slots symmetrically located about the substrate slot so that the mechanism can be mounted to a left side or a right side of the connector. The symmetric slots eliminate the need for a left side mechanism and a right side mechanism. The retainer mechanism may also have a nut retainer that captures a nut that is used to attach the mechanism to the printed circuit board. The nut retainer allows the nut to be transported with the retainer mechanism during an assembly process.

Abstract: To provide a computer device wherein liquid penetration into a ventilation hole from its periphery can be prevented or reduced without sacrificing design and without limitation of the size and operation. Coating films 7a and 7b in frame form are applied on a periphery of a ventilation hole 6. A wet-characteristic of the coating film 7a and 7b is different from a wet-characteristic of material composing a housing 3. For example, when an angle of contact of coating films 7a and 7b for water is larger than an angle of contact of material composing the housing 3, if water is spilled on the outside of the coating film 7b the coating film 7b prevents the water flow into the ventilation hole 6.

Abstract: A connector plug is provided including a plug body formed along a longitudinal axis and holding multiple contacts arranged in differential pairs.

The connector plug also includes a wire guide having a first end configured to join an end of the plug body. The wire guide has a second end configured to receive a cable containing twisted differential pairs of wires. The wire guide has guide slots that carry corresponding twisted differential pairs of wires. The second end has wire dress grooves extending from the guide slots to the channels. Each of the wire dress grooves receives a wire.

Abstract: A connector assembly for a memory module includes a body having two standing pivot seats and two fasteners pivotally connected to the two pivot seats respectively. Each standing pivot seat has two recessed guides and two through pivot holes communicating with two recessed guides. Each fastener has a front and rear wall.
