Housing for circuit cards

摘要

A housing for a plurality of electronic circuit cards is provided. The housing includes a shell and a single door adapted to selectively close the shell. The housing has a first shelf having opposing first and second edges in frictional engagement with the shell to thermally couple the first shelf to the shell. Moreover, the housing has a second shelf having opposing first and second edges directly contacting the shell to thermally couple the second shelf to the shell. The first and second shelves define a space therebetween for containing the plurality of electronic circuit cards. A backplane is disposed within the shell. The second shelf is removably attached to the shell to enable the backplane to be installed or removed via the single door.
