Abstract: A circuit board module has a circuit board which includes a circuit board structure and a set of components mounted to the circuit board structure. The circuit board module further includes a set of heatsinks (i.e., one or more heatsinks) and a heatsink retaining assembly fastened to the circuit board. The heatsink retaining assembly includes (i) a set of brackets, each bracket being elongated in shape and having a first end and a second end, (ii) a frame, and (iii) a fastening mechanism configured to fasten the frame to a circuit board. The frame is configured to simultaneously hold the first and second ends of each bracket relative to the circuit board to enable that bracket to assert holding force on the set of heatsinks.

Abstract: A tool device for selectively extracting, installing, and removing a plurality of optical connectors is disclosed. The tool device has a prying end coupled to a grasping end. The prying and the grasping end are intercoupled by a pair of arms, which is disposed to transmit a grasping force to the grasping end. With respect to the various types of optical connectors and their receptacles that it can be used to extract, install, or remove, the tool device is versatile. The tool can be used on optical connectors of types including ‘MTP’, ‘MPO’, ‘MT-RJ’, ‘MU’, ‘LC’, ‘SC’, and on SFP optical connector receptacles.

Abstract: An apparatus for managing the routing of a cable intercoupling two components in an installation is disclosed. The apparatus has a drawer for storing a portion of the cable and a drawer for cross-connecting the cable, which is connected to one component, with another cable, which is connected to the other component. The apparatus can be used with optical and electrical cables.

Abstract: A grounding plug structure configured for push-type snap lock fastening in circuit board screw holes is provided with a resilient deformable conductive member. When a circuit board with one or more such plug structures fastened thereto is mounted with respect to a tray or chassis, the conductive portion of the plug structure is deformed against a surface of the tray, forming an effective conductive pathway, e.g., for grounding, between the tray and the circuit board. In this way, grounding pathways can be established while eliminating the need for at least some screw mounting and/or standoff structures.
