Abstract
Abstract A low-cost package for electronic components is achieved by utilizing an egrally molded, lightweight plastic enclosure having a laminated construction with inner and outer shells fabricated of lightweight, high-impact resistant plastic having sandwiched therebetween a suitable filler material to provide stiffening and structural damping. Self-contained heat pipes may be imbedded in the shell walls to provide the necessary cooling. The inner shell is formed with the necessary drawer or chassis supporting hardware through the use of molded-in-place inserts. The interior wall surfaces of the inner shell may be vacuum metalized to provide required radio frequency shielding.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
106 words
An electronic instrument enclosure comprising: molded outer and inner spaced independent shells having walls, each shell having a common front opening; a drawer for supporting an electronic package positionable within said opening; a filler material having structural dampening properties intermediately positioned in the spaces between said walls of the outer and inner shells forming an integral sandwiched construction; said outer shell constructed of a hard, impact-resistant plastic material; the inner surfaces of the outer shell having formed therein recesses; self-contained heat pipes positioned within said recesses to provide a passive cooling system for the electronic package; said inner shell walls having imbedded therein hardware supporting components.
Claim 2
Dependent Claim
106 words
An electronic instrument enclosure comprising: molded outer and inner spaced independent shells having walls, each shell having a common front opening; a drawer for supporting an electronic package positionable within said opening; a filler material having structural dampening properties intermediately positioned in the spaces between said walls of the outer and inner shells forming an integral sandwiched construction; said outer shell constructed of a hard, impact-resistant plastic material; the inner surfaces of the outer shell having formed therein recesses; self-contained heat pipes positioned within said recesses to provide a passive cooling system for the electronic package; said inner shell walls having imbedded therein hardware supporting components.
Claim 3
Dependent Claim
