  • Publication number: 20100046190
    Abstract: To effectively suppress an adverse effect of radiation of electrical noise on other electronic circuits and increase the mounting strength of the electronic part on the substrate, where the electrical noise is noise emitted from an electronic part installed on a substrate. The tip of a nozzle for filling with a reinforcing resin is protruded into a noise shielding case through an elongated hole formed in the top board part of the noise shielding case, and the reinforcement resin is placed between the lower surface of the electronic part and the upper surface of the substrate. This realizes the noise shielding case in which a peripheral wall part surrounding the outer surfaces of the electronic part and the top board part covering the upper surface of the electronic part are integrated together. The noise shielding case prevents leakage of radiation of electrical noise from the electronic part.

  • Patent number: 7667985
    Abstract: One embodiment of the present computer network device comprises a subassembly. The subassembly includes a support plate, a standoff extending from the support plate, a printed circuit board (PCB) secured to the standoff, an electromechanical connector secured to the PCB, an electromagnetic interference (EMI) cage secured to the PCB, and an EMI gasket engaging the EMI cage. The computer network device further comprises a guiding and retaining member that engages the support plate and assists in securing the subassembly within an enclosure. In a method of assembling the computer network device, the subassembly is first assembled before the subassembly is secured within an enclosure. Relative motion of the PCB and the standoffs is thus eliminated during the assembly process.

  • Patent number: 7667984
    Abstract: The present invention is directed to an apparatus for reducing and constraining EMI (electronic magnetic radiation) emissions without affecting the internals of data storage system components. A baffle is attached to the exterior of the housing of a data storage system component by baffle mounts. The baffle is operable between a closed position, where the baffle blocks EMI emitted by connectors on the data storage system component, and an open position, where the connectors are not blocked allowing for servicing and cable management. The baffle may comprise an EMI absorbing material and be tuned to meet specific EMI requirements. The baffle mounts offsets the baffle from the data storage system component and the baffle includes a number of holes to allow airflow. The adjustable EMI baffling apparatus does not interfere with other mounted components while the data storage system component is mounted in a cabinet.

  • Patent number: 7606045
    Abstract: A head or bottom element of a component support, having guide rails arranged side-by-side and aligned in an insertion direction for receiving a printed circuit board of a plug-in module, wherein the guide rails are formed by one-piece guide elements of the head or bottom element. The guide elements can be formed of two rows of several guide strips per guide rail, each of which extends in the insertion direction, which strips are punched out of a plate-shaped head or bottom element and are projectingly beveled in the direction toward an underside of the head element or a top of the bottom element. A distance of the guide strips of the guide rails is matched to the thickness of the printed circuit boards of the plug-in modules. The head or bottom element forms guide paths for the printed circuit boards of the plug-in modules between the rows of guide strips of the guide rails.

  • Patent number: 7589978
    Abstract: An air inlet diffuser 10 is disclosed for attachment relative to an air inlet opening 106 of an electronics enclosure 100. The diffuser 10 extends into the electronics enclosure 100 and provides an increased surface area through which EMI attenuating apertures may be formed. The diffuser 10 also reduces the amount of structure that is disposed within the air inlet opening 106 thereby reducing impedance to airflow through the opening 106 into the enclosure 100. The increased surface are of the diffuser 10 allows for increasing the number of EMI attenuating apertures that may be utilized for a given inlet opening 106. In one embodiment, the total open area of the EMI apertures is greater than the open area of the air inlet opening. In such an embodiment, the EMI apertures provide low impedance to airflow through the diffuser 10 and increased airflow in conjunction with EMI attenuation may be realized.

  • Patent number: 7570496
    Abstract: An electromagnetic interference shielding apparatus for a signal transceiver employs two folded-edge mechanisms coupled together and an adhesive. The electromagnetic interference shielding apparatus includes a metal cover, a chassis having a waveguide output hole, and an adhesive. A first combination portion having a first curved section is disposed on an edge of the metal cover. A second combination portion having a second curved section corresponding to the first combination portion is disposed on an edge of the chassis. The adhesive is used to combine the first combination portion and the second combination portion. The waveguide output hole outputs a signal transmitted by the signal transceiver. The first combination portion and the second combination portion form a curved space that is used with the adhesive to prevent leakage of the transmitted signal and the interference of external noises.
