ABSTRACT:
Electrical terminals for a wound capacitor section and a method of attaching the electrical terminals to the section are disclosed. Adjacent convolutions of a wound capacitor section are electrically connected to one another through conventional metal spraying techniques. Flat copper tabs having the surfaces thereof tinned, as with a thin layer of solder, provide the terminal connection leads for use of the capacitor in an electrical circuit. The tinned copper tabs are secured to either end of the capacitor section by tack welding the tab to the sprayed metal end of the winding. Tack welding of the tab to the metal coating insures electrical connection but provides little strength in mechanical connection. Each end of the capacitor section is then again provided with a sprayed metal coating over both the first coating and the tinned tabs.
