In one embodiment, a removable storage module for use in a module cage includes a latch mechanism including: a latch arm that is used to rotate the mechanism about an axis, and a top portion that includes at least one latch tooth and a paddle member, the latch tooth comprising a first surface that is adapted to abut a rear side of a first flange of the cage during insertion of the module and a second surface that is adapted to abut a second flange of the cage during removal of the module, the paddle member being adapted to abut a front side of the first flange during removal of the module.

Removable storage modules

Front bezel

In one embodiment, a removable storage module includes a bezel, and opposed first and second rails that extend from the bezel, the first rail including a key system component that is adapted to prevent full insertion of the module into a bay of a module cage so as to protect a connector of at least one of the module and the cage. In another embodiment, a removable storage module for use in a module cage includes a latch mechanism including: a latch arm that is used to rotate the mechanism about an axis, and a top portion that includes at least one latch tooth and a paddle member, the latch tooth comprising a first surface that is adapted to abut a rear side of a first flange of the cage during insertion of the module and a second surface that is adapted to abut a second flange of the cage during removal of the module, the paddle member being adapted to abut a front side of the first flange during removal of the module.

A heat sink assembly for use with edge connectors, e.g., card edge connectors, of cards or printed circuit boards. The heat sink assembly provides a relatively large heat transfer capacity to control temperatures in contacts of the edge connectors which increases the current rating of the connector by allowing more current to pass through the connector. The heat sink assembly includes fins attached to the edge connector power and ground leads by direct thermal connection, such as soldering, to traces in the board. The fins are connected to the power and ground leads in an alternating or interweaved fashion. The fins are fabricated from thermal conducting material and heat is conducted to the fins where it is removed by the relatively large surface area of the fins. Adjacent fins are electrically isolated such that power and ground fins do not contact.

A low static enclosure has an interior for holding an electronic device therein. The electronic device has opposing walls each having a guide rail thereon. The enclosure has a bottom, a top, and a backplane between the bottom and top at their respective back edges. The backplane has an electric connector on its interior surface. The bottom and top each have a flat continuous interior facing surface with a groove extending from the front edge to the back edge. The grooves on the bottom and top are for cooperation with the guide rails on the opposing walls of the electronic device to slide the electronic device along the bottom and top respectively so that an electric connector on the electronic device mates with the electric connector on the interior surface of the backplane. The flat continuous interior facing surfaces of the bottom and top discourage ESD between the surfaces and the electronic device.

Reduced static raid enclosure

An apparatus is provided to reduce the amount of EMI generated by a circuit. The grounding of an enclosure is improved by providing a number of shaped protuberances, the protuberances having an end that penetrates a conductive region of a circuit board, such that when the circuit board is mounted to the support member, the protuberances make a penetrating electrical contact and provides for additional ground paths, thereby reducing the EMI generated by the assembly.

Grounding for enclosures

An arrangement for mounting a heat sink to a mounting board. The arrangement includes a heat sink and a locking member. The heat sink has a bottom surface and a passageway extending therein from an entrance opening on the bottom surface in a direction normal thereto and terminating with a closed end at its inner end. The passageway has an entrance region tapering toward the closed end and an inner region defined by generally parallel side wall portions. The side wall portions defining the entrance region including an engagement surface facing the closed end of the passageway. The locking member is T-shaped with the member crossing the stem of the T adapted for snug fit engagement with the generally parallel walls of the passageway's inner region. Moreover, the crossing member has an engagement member at each of it's ends that extend toward the base of the stem. The engagement members interlock with the engagement surface when the locking member is inserted into the passageway of the heat sink.

This disclosure pertains to an apparatus and method of providing EMI shielding for an electrical component. The apparatus includes an elastomeric gasket, which is coated with a conductive jacket, and which is mounted on the backplane of a cabinet, the backplane providing EMI shielding. The cabinet is adapted for the insertion of a plurality of electrical components, such as disk drives, tape drives, and power supplies, which themselves are mounted in a rigid frame member. The frame member includes EMI shielding for the components on five of their six sides. The sixth side is unshielded, due to the fact that it contains the electrical connector used to connect the component to the backplane of the cabinet, when the frame member is inserted in the cabinet. With the frame member providing shielding on five sides, and the backplane providing shielding for the sixth side, the gasket serves the purpose of establishing an electrical seal between the frame member and the backplane of the cabinet.

EMI shielding for components

Modular enclosure for electronic equipment

A simple, low cost, reduced tolerance interconnect enclosure in which a blind m A siVpV:interconnect between modules and the backplane may be guaranteed without the need for assembly fixtures or floating connectors, and a method of manufacturing the enclosure. The enclosure includes two matching enclosure sections for holding a backplane. The backplane has spaced apart recesses on opposing edges. Each enclosure section includes alignment protrusions spaced apart to engage the backplane recesses. These protrusions have curved apex regions and a height greater than the depth of the backplane recesses. Means for latching the enclosure sections together are provided, and the enclosure sections are dimensioned such that when the enclosure sections are closed around the backplane, the protrusions from the enclosure sections are urged against the recesses on the backplane. The resulting multi-point-of-contact interference fit between the backplane recesses and alignment protrusions automatically centers the backplane in the shelf. The process for manufacturing the enclosure includes the steps of drilling holes in a panel and routing the backplanes from the panel such that the routing path crosses the drilled holes, creating recesses on the backplane edges. The enclosure sections are manufactured according to a unitary injection molded plastic process.
