  • associated hardwired circuitry to effectuate data reception and transmission as well as data display on a cathode ray tube.
  • Data terminals such as discussed above, are 15 generally contained in metallic housings, the circuitry being hardwired to various support substructures within the metallic containment.
  • These prior art devices have been extremely sensitive to shock and magnetic flux and are quite difficult to repair.
  • 20 There has recently been attempts to more conveni ⁇ ently service electronic circuitry.
  • U.S. Patent No. 4,232,356 a logic card frame is disclosed whereby printed circuit boards can be slide- ably inserted and removed from a unitary structure for 25 servicing.
  • the present invention comprises the unitary housing for a data terminal having a cathode ray display (not shown).
  • the housing comprises a first molded structural frame 1 for supporting the cathode ray tube element within opening 2.
  • a rear molded structural frame 3 is taught for securing the side walls of the housing 4 and 5.
  • the two molded side wall structural frames are fixedly connected to the front and rear structural frames -1 and 3 and possess a multiplicity of circuit board tracks 6, 7 and 8 for guiding inserted printed circuit boards (not shown).
  • the tracks are dimensioned so that the printed circuit boards are pressure fit within said tracks.
  • On the interior side walls 11 of front molded structural frame 1 are imbedded bus connectors (not shown) which are designed to contact appropriate peripheral seg ⁇ ments of the printed circuit boards so that electrical connections are effectuated instantly upon full inser ⁇ tion of the boards.
  • the unitary housing of the present invention be fabricated of structural foam.
  • the housing be fabri ⁇ cated of a foam formed from acrylonitrile styrene resin
  • the structural foam housing offers impact resistance which is often encountered by any data terminal.
  • the insulative properties of the housing help to minimize magnetic flux which influences the cathode ray tube output.
  • the printed circuit board tracks are made of insulative material, one need not insulate the periphery of the printed circuit boards prior to insertion.
  • the tracks 6, 7 and 8 be of a dimension so that the printed circuit boards are pressure fit within the tracks. That is, the internal dimensions of the trakcs are configured to be extremely close to the outside dimensions of the periphery of the printed circuit boards. Thus, the printed circuit boards can be pressure fit into the tracks and held by friction. Once in place, screws can be inserted at 12 and 13 within the side walls to prevent the printed circuit boards from being inadvertently removed. It should further be noted that the unitary housing of the present invention has not been provided with a- bottom cover. By providing- an open bottom, the lower most printed circuit board can be serviced directly without any circuit board removal.
  • the unitary housing of the present invention be comprised of four individually molded structural frames 1, 3, 4 and 5. It is a further optional expedient to configure side walls 4 and 5 to be interchangeable and thus reduce the number of molds necessary in producing the unitary housing.

Abstract

Le champ d'application de l'invention et son utilisation principale se situent dans le domaine des boitiers pour terminaux et l'emballage des instruments. Les dispositifs de l'art anterieur sont extremement sensibles aux chocs et aux influences magnetiques et s'averent difficiles a reparer. On decrit un boitier unitaire pour terminal pourvu d'un affichage a tube cathodique qui comprend un cadre frontal moule (1) destine a supporter un tube cathodique, un cadre arriere moule (3) pour la fixation des parois laterales du boitier, ainsi que deux cadres lateraux moules (4 et 5) fixes au cadre frontal et au cadre arriere. Les cadres lateraux sont pourvus de multiples logements pour circuits imprimes (6, 7 et 8) destines a guider et retenir des plaques de circuits imprimes.
