The invention is a system for securing the data stored within a computer. The system 10 includes a cabinet 11 having a peripheral frame 12 with at least one drawer 22C having a front panel 24C moveable from a closed position to an open position. The drawer 22C is adapted to hold that portion 26 of the computer containing the data to be secured. The system further comprises electrical connector halves 28, 29 mounted in the front panel 24C of the drawer 22C having electrical cables 30 and 31 coupled to the portion 26 of the computer therein. The connectors are adapted to mate with external electrical connector halves 32, 33 attachable thereto. A cover 48, mounted to the cabinet, is moveable from a first position covering the electrical connector halves 28, 29 to a second position allowing access thereto. A lock 63 is provided which is adapted to lock the cover to the cabinet.

The invention is a circuit board housing for electrically coupling at least one circuit board 14 to a mother board 20 mounted within the housing 10, the circuit board 14 having a plurality of first electrical terminals 90 mounted along an edge portion thereof. The housing has at least one zero insertion force socket 12 wherein a plurality of second electrical terminals 18 are mounted therein. An electrical connector 16 is provided to couple the printed circuit board 14 to the mother board 20. The electrical connector 16 comprises a circuit board support member 26 slideably engageable with the socket 12. A pair of jaws 40a and 40b are attached to the support member 26 which are adapted to releaseably engage the edge portion of the circuit board 14. The electrical connector further comprises first and second resilient pads 62 and 63 mounted within the jaws. A resilient member 66 is rotatably mounted to the support member 26 moveable from a first position out of engagement with the plurality of second electrical terminals 18 to a second position in engagement therewith. A flexible conductor element 60 is provided having first and second ends incorporating a plurality of first electrical contacts 80 and a middle portion having a plurality of second electrical contacts 84 with the plurality of first and second contacts electrically joined by insulated electrical conductors 82. The first and second ends are wrapped about and joined to the first and second pads 62 and 63, respectively, and the middle portion is wrapped about and joined to the resilient member 66. Thus, when the circuit board 14 is in place and the electrical connector 16 installed in the socket 12 rotation of the resilient member 66 from the first position to the second position makes electrical contact between the plurality of first and second electrical terminals 90 and 18.

Each individual module includes a sealed chamber containing the electronic components being cooled, the liquid cooling medium, and at least one minature evaporator. The evaporator's outer surface area is in direct contact with the cooling medium, so as to maintain it at a desired temperature. Preferably, in order to minimize the weight associated with the liquid cooling medium and in order to compensate for its coefficient termal expansion and the associated internal pressure variation, the chamber may be packed with resilient spheres that will displace a substantial quantity of the cooling medium without a corresponding increase in its effective viscosity (and thus without any substantial effect on the liquid's capability of transferring heat from the components to the evaporator by means of thermal convection currents). The mechanical, electrical and refrigerant connections between the module and the other assemblies of the avionics system are such that the individual module may be readily removed and replaced thereby further enchancing the overall maintainability of the system. An expansion bladder vented to the external environment may also be provided within the chamber.
