A connector assembly is provided having a cable end plug with a body adapted to be connected to a cable with a connector part, and at least one outwardly extending flange on the body. A mating receptacle receives the cable end plug. The receptacle has a body with a complementary connector part to the cable end plug connector part. A retention clip is connected to the receptacle body, and includes at least one spring arm extending outwardly therefrom with a distal entry ramp portion, a retaining shoulder portion and a flange receiving portion. A thickness of the flange is approximately equal to a depth of the flange receiving portion so that the retaining shoulder portion engages behind the flange in a connected position of the cable end plug in the mating receptacle. For release, the retaining shoulder can be set at an angle of at least 94&#xb0; to the flange receiving portion to form a release ramp that allows disengagement when a sufficiently high predetermined release force is applied to the cable end plug. Alternatively, the retaining shoulder is set at about 90&#xb0; and ejector tabs are provided on the cable end plug to disengage the spring arms.

Electrical power strips and electrical power strip assemblies are disclosed. An electrical power strip assembly includes electrical outlets for receiving power cord plugs. Strap mounts are provided, wherein each strap mount includes a connection point associated with one of the electrical outlets. A housing supports the electrical outlets in a connection plane and supports the plurality of strap mounts. Each strap mount connection point is proximal to the connection plane and to the electrical outlet associated with that strap mount connection point. Straps are coupled to the strap mounts. Each strap is configured to releasably secure a power cord plug received by one of the electrical outlets to the associated strap mount at the connection point.

A packaging configuration is provided for a computer system that is adapted for operating multiple operating systems in different partitions of the computer system. The packaging configuration includes a main chassis having a main circuit board. The packaging configuration also includes a processor assembly configured for insertion into the main chassis. The processor assembly has a circuit board for connection to the main circuit board upon insertion of the processor assembly. The packaging configuration also includes a processor subassembly configured for insertion into the processor assembly. The processor subassembly includes a circuit board and a processor and is configured for connection with a circuit board in the processor assembly upon insertion of the processor subassembly. The processor assembly is removable from the main chassis without powering down the computer system, and the processor subassembly is removable from the processor assembly without powering down the computer system.

An apparatus is provided for dissipating heat from an electronic component, such as a processor, that is mounted in a conductive enclosure and for shielding electromagnetic radiation generated by the electronic component. The apparatus includes a heat sink that is configured to be mounted to a surface of the electronic component. The apparatus also includes a conductor connected to the heat sink. The conductor is configured to provide electrical contact between the heat sink and a surface of the conductive enclosure. Accordingly, the apparatus at least partially shields the electromagnetic radiation generated by the electronic component. A corresponding method is also provided.

The cooling of a heat generating component mounted outside of the main portion of an enclosure that is cooled using an airstream created by an active air handler is disclosed. The invention is preferably used to cool components such as displays that generate heat, but which are mounted outside the enclosure that houses the main electronics package. The disclosed system, permits inlet air to enter via a vent, and a first duct formed by a baffle routes the inlet air along the back of the displays, removing excess heat. The air is then channeled by a second duct to an area adjacent the enclosure. Since the airstream within the enclosure has created a low pressure area, the passive air stream infiltrates the enclosure and mixes with the main airstream. The disclosed system thus cools the remotely mounted components passively, without requiring additional air handlers or diminishing the pressure and velocity within the enclosure.

Modular fascia cover assemblies for rack mounted equipment are disclosed. In a system comprised of several pieces of equipment mounted in a standardized rack, vertical spaces typically exist between the components. These spaces can be filled with fascia cover assemblies, and the present invention provides a modular system that permits openings of nearly any width to be filled. The fascia cover assembly is created by choosing a combination from a few standardized modular parts. The fascia cover assemblies disclosed preferably include components such as an operator panel and pull bar that can be included, respectively, at the top and bottom of the assembly. Most preferably, the operator panel is one and one-half units high and the pull bar is one-half unit high. A cover panel that is one unit high is also included. In certain embodiments, a larger cover panel component is also provided that is three units high. The modular panels are assembled on to a frame carrier that is preferably stamped from sheet metal to permit easy and inexpensive fabrication in any number of sizes. In preferred embodiments, the frame carrier and assembled panels are mounted to a rack using spring clips that are attached to the frame carrier.

A lead-in guide and starting locator for use with a sheet metal card guide or similar structure is disclosed. The disclosed lead-in guide is preferably of a one piece construction and is most preferably molded or machined from a plastic material. The lead-in guide of the present invention provides multiple board lead-in slots and preferably includes integral retention pegs for quick mechanical attachment or can be held in place by a separate fastener. In a preferred embodiment, the lead-in guide has a top surface cut by a series of grooves that will be aligned with the slots in the card guide. Preferably, the lead-in guide has a front section that is somewhat thicker than the rest of the lead-in guide. As explained below, this permits the grooves to be cut to a depth such that the bottom of the groove in the thicker section is aligned with the bottom of the slots in the card guide, and the groove through the thinner section is actually cut all the way through such that its bottom surface is the sheet metal rack when it is installed.

A spring clip for releasably attaching a first member, such as the carrier of a fascia panel cover, to a second member, such as an electric component rack module. The spring clip is anchored to a support plate extending from carrier. The spring clip has two forwardly extending U-shaped spring elements that cooperate with a locking tab and a rearwardly extending U-shaped spring element. Deformation of the forwardly extending spring elements during installation of the spring clip causes the locking tab to snap onto the lower edge of the support plate, thereby firmly anchoring the spring clip to the support plate. A latch extending from the rack module engages the rearwardly extending spring element so as to secure the fascia cover panel to the rack module. Application of a force to the rearwardly extending spring element causes elastic deformation of the forwardly extending spring elements and disengages the locking tab.

Snap-lock spring clip attachment system

A hold down device is described for applying a high clamping force to a 'leadless' integrated circuit package installed in a suitable connector. Use of the device results in reliable electrical connections between the package circuit leads and the connector contact elements; and reliable thermal connections between the package carrier and a cooling frame provided to dissipate the heat generated by the integrated circuits. The hold down device has added system utility in the clamping of an interconnect cable assembly adapted to plug into the aforementioned connector in lieu of the integrated circuit package.
