Abstract
Abstract In a flight instrument having indicator assembly and heat generating electronics assembly, integral and thermally conductive structural supports are provided for each assembly. The assemblies are fastened together with shouldered screws such that there is some relative movement between the assemblies. The fastened assemblies are enclosed in a one piece housing, and the relationship between the structural supports and the housing facilitates heat transfer from the instrument.

Claim 1
Independent Claim
194 words
An instrument container comprising: a front assembly having a mounting plate with tapped screw holes therein; a longitudinally extending first frame rigidly, attached to said mounting plate, a second frame, longitudinally disposed relative to said first frame, including heat conductors adapted to thermally couple to heat generating elements, said heat conductors having tapped screw holes therein located at predetermined positions thereon, a cover having holes therein positioned over said first and second frames, a connector between said first and second frames adapted to provide relative longitudinal position adjustment of said first and second frames after connection thereof to align said tapped screw holes of said first and second frames, including said tapped screw holes in said heat conductors with said holes in said cover, thereby compensating for tolerance build-up during assembly, and screws passing through said holes in said cover and threaded into said tapped screw holes in said first and second frames to provide tight physical contact of said first and second frames, including said heat conductors with said cover to establish structural rigidity and integrity, and provide for heat conduction from said second frame to said cover for dissipation therefrom by convection.
