An extendable enclosure for circuit cards provides the capability for a customer to purchase a low cost system up-front, but still allow for growth. The extendable enclosure for circuit cards comprises a first enclosure comprising a backplane, a plurality of circuit card connectors, the backplane providing electrical connectivity among the plurality of circuit card connectors, a midplane connector mounted to the backplane, the midplane connector providing electrical connectivity to the backplane, and a backplane connector mounted to an edge of the backplane and providing electrical connectivity to the backplane and a second enclosure comprising a backplane, a plurality of circuit card connectors mounted to a face of the backplane, the backplane providing electrical connectivity among the plurality of circuit card connectors, and a backplane extension connector mounted to an edge of the backplane and providing electrical connectivity to the backplane, wherein the backplane extension connector is operable to plug into the backplane connector of the first component enclosure.

A fluid flow management system for enhancing cooling of a circuit pack. The system includes a bar extending transverse to the direction of fluid flow. The bar breaks up the otherwise laminar flow into a turbulent flow.

A rotatable latch is provided for securing an object to a holder and for preventing unintended removal of the object. In a preferred embodiment, the rotatable latch has at least two actuators flexibly mounted to a body. Each actuator has a hooked portion which engages a portion of the holder. A lever portion may be provided for releasing the hooked portion. The hooked portion is rotated about a pivot point to release the object from the holder. Rotation occurs when actuators are released through use of at least two lever portions. To prevent accidental removal of the object, the second actuator cannot be released until the first actuator has been released. The latch requires at least two actions, pressing the levers in succession, to release the object. The invention is applicable, for example, to circuit packs for electronic circuit boards.

A fuse for interfacing electrical current with electronic components and for shielding the electronic components from potentially damaging electrostatic discharge. The fuse includes a fuse body having an edge and first and second electrical contacts. A fuse indicator is connected to one electrical contact and a fuse element extends between the indicator and the other contact for providing a conduit for operating current to reach the interfaced electronic components. A window is disposed on the edge of the fuse body and positioned over the fuse indicator. Sealant is disposed between the window edge and the fuse body edge to prevent the accumulation of air therebetween and, thereby, preventing such accumulated air from functioning as a transmission medium through which an electrostatic discharge can travel and reach the electronic components.
