Abstract
An extended foil capacitor has a conductive disk electrically connected in oncrushing contact to the extended foil. A conductive paste is placed through spaces between radial spokes on the disk to electrically and mechanically connect the extended foil to the disk.
Claims7
An extended foil capacitor comprising:
- a convolutely wound cylindrical capacitance section comprising first and second electrically conducting foils separated by dielectric layers;
- one edge of a first conducting foil extending longitudinally beyond one edge of each of said dielectric layers, the other edge of each of said dielectric layers extending longitudinally beyond the other edge of said first conducting foil;
- the one edge of each of said dielectric layers extending longitudinally beyond one edge of a second conducting foil, the other edge of said second conducting foil extending longitudinally beyond the other edge of each of said dielectric layers,;
- first and second electrodes for electrical connection, respectively, to said one edge of said first conducting foil and said other edge of said second conducting foil, wherein each of said electrodes comprises:
- a conductive sheet having a disk-shaped planar side, said sheet having:
- a plurality of radial spokes extending from an inner rim to an outer rim aligned approximately with the outer surface of said capacitance section;
- and
- a radial hole between each pair of adjacent spokes;
- and
- mounting means for holding said planar side in noncrushing contact with said extended edge.
