A removable apparatus for carrying a circuit board includes a carrying plate having a notch to receive a stationary pin of an enclosure and a faceplate connected to one end of the carrying plate. A rotating cam connects to the carrying plate and acts on the pin to move the apparatus relative to the pin during insertion into and removal from the enclosure. The cam includes two different surfaces, each of which acts to move the apparatus either into or out of the enclosure. A linkage is connected to the cam and extends through the faceplate, connecting to a lever on the exterior of the faceplate. The lever is used to rotate the cam, which in conjunction with the pin provides translational motion either to mate a connector on the circuit board with a corresponding connector in the enclosure or to separate the mated connectors, depending on the direction of rotation.

A circuit card module having increased cooling efficiency which comprises at least one printed wiring board (PWB), at least one component mounted on the PWB, a heatsink, an interchangeable frame, and a wedgelock for use with a chassis cold wall. One embodiment of the interchangeable frame comprises a protrusion so that it can be used with a convection-cooled chassis (fully compliant with IEEE 1101.2 Specifications). Another embodiment, for use with conduction-cooled chassis only (partially compliant with IEEE 1101.2 Specifications), is maximally efficient in removing heat as it does not include the protrusion. In the embodiment without the protrusion, the conduction contact area between the chassis cold wall and the frame is increased in width from approximately 0.25'' to approximately 0.35''. In either embodiment, the wedgelock is mounted to one surface of the frame such that when installed in a conduction-cooled chassis, the opposite frame surface is forced against the chassis cold wall. In addition, the wedgelock can be enlarged to increase the clamping force over the contact area. The increased wedgelock size approximately doubles the clamping force applied. The net effect of these improvements are a reduction in the thermal resistance per inch of wedgelock length. This, in turn, reduces the module to chassis interface temperature rise of an exemplary 40 W module from 8.3° C. to 4.15° C. The improved thermal resistances and decreased temperature rises boost the reliability of the circuit cards, particularly in the stringent environments experienced in military applications.

An electrical enclosure wherein an electrical component can be moved between various positions (e.g., connected, disconnected, test, etc.) without opening an enclosure door. The electrical enclosure supports a component for movement between a withdrawn position, a test position, and an inserted position. A handle is accessible by an operator from an exterior of the enclosure and is configured to move the component between the respective positions without having to open the enclosure. The handle is integral with the enclosure and thus an operator needs no special tool or other device to effect movement of the electrical component between its respective positions.
