Abstract
A terminal-cover assembly for a multisection capacitor has three terminal-bushing assemblies mounted in a round metal cover so as to meet the minimum spacing requirements between terminals and between the terminals and the edge of the cover. The terminal-bushing assemblies are mounted in the cover in a triangular array, and the bushings have an irregular pentagonal shape. A four-bladed terminal in the shape of an irregular octagon is provided for the assembly.
Claims7
A cover-terminal assembly for a multi-section capacitor comprising a round metal cover having a rim portion and three terminals mounted therein in a triangular array, each of said terminals having a plurality of flat blade portions and being located in an insulative bushing having a pentagonal shape, there being at least minimum safety distance between any blade portion of any one of said terminals and any blade portion of any other of said terminals and between any blade portion of any of said terminals and a vertical plane in which an edge of said cover lies, wherein each of said bushings has a curved edge that lies on an imaginary circle concentric with and smaller than the cover, two straight edges that form an apex pointing to the center of said cover and lying opposite said curved edge, and two straight edges parallel to each other and each joining an edge that forms said apex and said curved edge.
