    摘要: An arrangement for providing radio frequency and electromagnetic interference protection to at least part of circuitry mounted on a circuit board comprises alternating slots and bridges which form a boundary between a protected area of the circuit board and an unprotected area of the circuit board. The circuit portions which require protection are mounted in the protected area and are covered by a top cover having fingers which extend through the slots. Connecting lines between the protected and unprotected portions of the circuit portions extend along the bridges between the slots. A bottom cover engages under the protected area and mates to the top cover for providing electromagnetic interference protection for the circuit portions within the protected area.

    摘要: A method for contacting shielding plates having press-in pins and attached to an upper side of a printed circuit board to further shielding plates also having press-in pins and located on a lower side of the printed circuit board. The upper shielding plate with press-in pins having arcuate press-in zones is placed free of force into respective through-contacted printed circuit board holes and is contacted against walls of the holes by pressing into the same holes press-in pins having V-shaped press-in zones of the lower shielding plate in order to achieve a gas-tight, good contacting, i.e. a shielding diverter.

    摘要: An electromagnetic shield for absorbing electromagnetic energy generated by a circuit disposed upn a circuit board. The shield is comprised of a thermally conductive material to further provide heat-sink capabilites. Clip members releasably fastened to a flange projecting from a shielding surface formed by the shield are aligned with the ground plane of a circuit board. By maintaining the shield in a confronting relationship with the circuit board, the clip members are caused to maintain the shielding surface in electrical contact with the circuit.

    摘要: Disclosed is an improved housing being comprised of a substrate and a cover that is plated to provide RF shielding. The substrate and cover are constructed of a like material to keep the coefficients of vibration approximately identical. Preferably, the substrate and cover material are ceramic thereby providing a rigid structure that minimizes vibration degradation.

    摘要: This disclosure illustrates and describes an apparatus and a method for preventing the interference by strong electrical fields with the operation of electronic equipment. There are many situations where a substantial amount of electronic equipment is located in an area which is subjected to strong radiation fields. One example of such a situation is the installation of an aircraft simulator at an air base which utilizes high powered radio transmitters and radar transmission equipment. Interference in the operation of the electronic equipment by the radiant fields may cause improper operation of digital computers, damaging transient effects and complete disruption of intercomponent communication. This invention is used where such equipment is mounted upon a raised floor and in which the cables interconnecting the electronic components pass beneath the raised floor. In accordance with this invention the raised floor is constructed upon a sheet of highly conductive material which is then folded up around the sides and the ends of the raised floor and electrically grounded thereto so that the floor, the sheet of conductive material, and the cabinets containing the electronic gear thereon are connected together and completely surround the electrical equipment and the connecting cables.
