  • Patent number: 5909359
    Abstract: An apparatus to extend printed circuit board length allows for secure mounting of the printed circuit boards. More particularly, the extender bracket apparatus (30) is for stabilizing small or short, commercial off the shelf (COTS) circuit boards (20) for personal computers (PC). The apparatus will aid in operation of small circuit boards for rugged applications such as high vibration conditions in vehicles. The extender bracket apparatus (30) is first fastened to an adjustable clamp (60), which is then fastened to a COTS circuit board. The adjustable clamp has holes that facilitate attaching to slots in the extender bracket apparatus. The clamp and extender board may have a dielectric surface to prevent electrical conduction. The dielectric can be an adhesive to hold the printed circuit board. The apparatus can then be fastened to a computer chassis (40) for rigidly mounting the circuit board.

  • Patent number: 5883792
    Abstract: An end bracket for ruggedization of Commercial Off-The-Shelf (COTS) printed wiring cards is described. End bracket (400) has flanges (420,430) with holes for attachment of end bracket (400) to free end (250) of printed wiring card (210). End bracket (400) also has a flange (440) for attaching end bracket(400) to a fixed structure. The holes in flanges (420,430) generally form a hole pattern that matches a standard hole pattern found in free end (250) of printed wiring card (210).

  • Patent number: 5822193
    Abstract: An apparatus and method for rigidly stabilizing or restraining circuit boards is provided. The apparatus has a rigid cross member (20) and a circuit board clamp (10). These provides stabilization of commercial off the shelf (COTS) circuit boards for use in harsh environments. A one piece clamp has hooks with notched ends that attach to opposite sides of each circuit board. The clamp has a surface parallel to the hook. The parallel surface has threaded holes. Threaded shafts are used with the threaded holes to contact the clamp hook and provide pressure on the printed circuit board. A threaded hole is used with a threaded shaft to engage a rigid cross member. The cross member has unthreaded holes to allow for attaching to the clamps with threaded fasteners. The rigid cross member is then attached to the chassis with a fastener. This eliminates flexing of the circuit board under vibration.
