A link member pivotally mounts to a bracket on a door frame. A follower mounts to an end of the link and slides along the slot in the guide member. The follower slides up and over the ramp when slid along the slot in a first direction and engages an abrupt edge of the ramp when slid in the opposite direction.

Abstract: An electrical enclosure having an improved sealing and shielding component and a method of manufacturing such an enclosure is provided. In accordance with an embodiment of the invention, a wire mesh is positioned against the surface of the enclosure. While the wire mesh is being positioned against the enclosure surface, a foam is formed on the enclosure surface adjacent the wire mesh. The foam generally adheres to the enclosure surface and holds the wire mesh in place. In accordance with one aspect of the invention, the foam has a height equal to or greater than the height of the wire mesh. The improved sealing and shielding components can, for example, improve the sealing and shielding of the electrical enclosure as compared to conventional electrical enclosures. The present electrical enclosure may, for example, also reduce the cost of manufacturing electrical enclosures.

Abstract: A support for a data storage device having at least one slots provided on each side surface comprises two elongate plates provided on each of two opposite sides of the device having at least one latched members raised on an inner surface thereof such that each of the latched members being capable of inserting into a corresponding slot for securing the elongate plates and the device together wherein each of the latched members is disposed at an angle 45° with respect to each of the elongate plates. By utilizing this, an evenly distributed stress exerted on the latched members is made possible when supporting the device for effectively preventing the latched members from breaking.

Abstract: A lay-in wireway includes channel members connected in an end-to-end configuration to form an enclosed rectangular channel. Covers hingedly connect to a flange extending from one side of the wireway. Hinges are then formed with the cover member and act as a stop to hold the cover member at an open position. Channel members connect with a hook and slot arrangement which slide relative toward one another at an end connector portion. Hooks and slots provide self-alignment of connected channel members when slid into position.

Abstract: A fixing device for interface cards includes a seat. A plurality of spacers are installed on one surface of the seat. Several teeth are mounted on the top end of the spacer, while the lower portion thereof is formed with a holding device. Furthermore, a sliding block is slidably engaged on the top portion of the spacer. The sliding block is formed with teeth corresponding to the teeth of the spacer. The fixing device can be mounted in the casing of a computer mainframe in correspondence with the circuit board inserting slot within a computer mainframe. Accordingly, when an interface card is required to be inserted into the computer, the sliding block is moved upwards. Then, the interface card is passed into the holding device, and then is inserted into the inserting slot of the main circuit board. Thereafter, the sliding block is moved downwards to rest against the top end of the interface card to fully fix the interface card.

Abstract: An air duct of a radiating fan having an air duct body and guide plates installed within the air duct body. A plurality of positioning holes with special arrangement are installed on the periphery of the wind outlet of air duct body. The front and rear sides of the guide plate are installed with pivotal pins. Thereby, the guide plate can be buckled to respective positioning holes so to form different angles with the air duct body. Therefore, the orientation and size of the channel of air flow is changed. As consequence, the guide plates can be installed on the wind outlet of the radiating fan of an electronic device and the airflow actually attains the predetermined place and the heat dissipating efficiency is increased.

Abstract: An electrical enclosure having a housing including a door. The electrical enclosure includes a frame assembly and a plurality of fasteners. The frame assembly has a first side including a planar portion opposite the door. The plurality of fasteners are disposed through the frame assembly for mounting the frame assembly to the door such that the fasteners do not protrude beyond the plane of the planar portion.
