Abstract
A tablet computer housing assembly and housing construction method. A molded front housing has a planar perimeter margin and a front opening for viewing a LCD screen which is sealingly mounted within the housing assembly. A front sealing bracket having an open central portion is rigidly connected along an outer margin thereof to, and forms a seal with, the perimeter margin of the front housing. A molded rear housing having a planar perimeter margin and a rear sealing bracket and having an open central portion is rigidly connected to, and forms a seal with the perimeter margin of the rear housing. A flat compressible main sealing gasket having an open central portion is positioned between the front and rear sealing brackets to form a sealed connection therebetween whereby a sealed interior volume is established within the mating housings.
