Abstract
Abstract An assembly for mounting a plurality of rectifiers to a pair of current conductors. The conductors are two overlying plates, separated by a layer or sheet of insulation between their inner faces. Each rectifier is a high-current device in the form of an annular washer, and is mounted to an outer face of one of the conductors. The mounting means is a fastener having a shank which passes through one or a stack of the washer rectifiers, into an aperture extending perpendicularly to the conductors. The shank of the fastener is insulated from the conductor against which the rectifier is held, but is in electrical contact with the other conductor and is secured relative to both. A head or nut on the fastener exerts mechanical force on, and is in electrical contact with, the upper surface of the rectifier. The rectifying circuit includes the shank of the fastener.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
233 words
A rectifier assembly comprising, a first conductor plate facially overlying a second conductor plate but electrically insulated from second plate by an insulator between them, an aperture extending through said first plate, a rectifier having parallel opposed first and second surfaces and adapted to rectify alternating current flowing from one said surface to the other, said rectifier disposed with one of its said surfaces in electrical contact with the outer face of said first plate, said rectifier having a hole therethrough perpendicular to its said surfaces, said hole being in line with said aperture, a rectifier fastener having a shank extending through the hole in the rectifier and through the aperture in the first plate, said fastener making an electrical contact with said second plate through said shank, said fastener including a portion mechanically engaging one of said plates to prevent axial movement with respect thereto, said fastener also having means connected to said shank, outwardly of said rectifier which exerts an axial compression force holding said rectifier in physical and electrical engagement with the outer face of said first plate, and insulating means around and within the aperture through said first plate, said insulating means electrically insulating said first plate but not said second plate from the shank of said fastener, such that current can flow between said plates only by passing through both said rectifier and the shank of said fastener.
