Peerenboom, B D; Sypal, K L

An improved housing construction for electrical apparatus is disclosed, the housing having particular utility as a housing suitable for an ionization detector array of a tomographic X-ray scanner. The housing comprises at least two mating sections which, upon assembly and juxtaposition one to another, form a closed interior chamber adapted to receive the detector array, or other electrical apparatus. A gasket means preferably comprising a so called ''flexible'' printed circuit constructed of a suitable polymer plastic is provided between the assembled mating sections of the housing to effect a sealing of the interior chamber. Electrical conductors, such as a metallic printed circuit foil, are disposed within the polymer material and extend between the interior chamber and the exterior of the housing. The conductors define means by which electrical connections can be made to electrical apparatus within the chamber, such as the detector array, and external circuitry. This construction eliminates the necessity of providing separate conductor feedthroughs in the housing. Further, the sealing of the chamber is enhanced through the provision of O-ring seals disposed in the mating surface of each of the two mating sections of the housing, the sealing rings being laterally offset one from the other such that when the mating sections are assembled and juxtaposed with the gasket means therebetween, the O-shaped sealing rings are staggered.
