DOUBLE-LAYER CAPACITOR Russian patent published in 2001 - IPC

FIELD: electrical engineering; low- voltage storage capacitors. SUBSTANCE: capacitor has hollow case 1 accommodating at least one stack 2 of storage sections 3 with current- collecting plates 4, 5, pressure slabs 6, 7 that cover case at ends and compress stack of storage sections, at least one pin-type current lead 8 electrically connected to current-collecting plate 4 and placed in hole 9 provided in pressure slab 6, as well as internal insulators 10-12. Novelty is that capacitor has external butt-end insulator 13 mounted on current lead 8 and connected through sealed joint to internal insulator placed in hole 9 of pressure slab about current lead 8 whose internal end is connected to current-collecting plate 4 through sealed welded joint. EFFECT: improved operating reliability of capacitor. 14 cl, 2 dwg
