Abstract
An electrode lead tab for oil-impregnated capacitors having dielectric sheets and electrode foils laminated to each other, in which a plurality of cutting lines or rifts are provided to a tab main body, so that the tab main body can ensure a close electrical contact at a plurality of regions thereof to the electrode foils.
Claims16
An oil-impregnated winding-type capacitor, comprising:
- a first dielectric sheet;
- a first electrode foil laminated to the first dielectric sheet;
- a second dielectric sheet laminated to the first electrode foil;
- a second electrode foil laminated to the second dielectric sheet;
- and
- a pair of electrode lead tabs, each of the electrode lead tabs being respectively disposed on one of the electrode foils, wherein the dielectric sheets, the electrode foils and the pair of electrode lead tabs are all wound up to form the capacitor, each electrode lead tab having a filmy flexible tab main body to be in contact with the electrode foil and a terminal strap being integrally formed with the tab main body and extending generally perpendicular to the winding direction of the capacitor, the tab main body having a plurality of rifts, which form small movable chips being defined by round U-shaped cut lines.
