Abstract:
A capacitor cover for closing an open end of a capacitor containing electrolyte, comprising:an elastomeric outer layer having an inner surface and a first aperture,a rigid middle layer having an outer surface, an inner surface, a peripheral surface, a second aperture and an annular surface defining said second aperture,a polypropylene inner layer having an outer surface, a peripheral skirt, a third aperture and an annular skirt disposed around said third aperture,said inner surface of said elastomeric outer layer being in contact with said outer surface of said rigid middle layer and said inner surface of said rigid middle layer being in contact with said outer surface of said polypropylene inner layer,said first, second and third apertures disposed so as to allow passage of a terminal through said capacitor cover,said peripheral skirt extending sufficiently to prevent said electrolyte of said capacitor from coming into contact with said peripheral surface of said rigid middle layer, andsaid annular skirt extending into said second aperture sufficiently to prevent said electrolyte of said capacitor from coming into contact with said annular surface of said rigid middle layer.
