Power factor correction capacitor

A power factor correction capacitor, comprising:

• a. one capacitor pack formed from two sheets of foil sandwiching at least one sheet of dielectric, one sheet of foil having two opposite edges and said one sheet of dielectric having two opposite edges with one of the edges of said one sheet of foil extending beyond the adjacent edge of said one sheet of dielectric and the adjacent edge of the other sheet of foil;
• clip means, piercing said one edge of said one sheet of foil, for electrically terminating said one sheet of foil in said one capacitor pack;
• wherein said two sheets of foil have a width generally equal to the width of said sheet of dielectric, whereby the other edge of said one sheet of foil is indented from the other edge of said one sheet of dielectric;
• wherein the other sheet of foil in said one capacitor pack has two opposite edges with one of said edges extending beyond said other edge of said sheet of dielectric in said one capacitor pack;
• another capacitor pack formed from two sheets of foil sandwiching at least one sheet of dielectric, each of said sheets of foil having two opposite edges, said sheet of dielectric having two opposite edges and a width generally equal to the width of said two sheets of foil with one edge of one sheet of foil offset in one direction relative to the adjacent edge of said one sheet of dielectric and with one edge of the other sheet of foil offset in the opposite direction from the other edge of said sheet of dielectric, whereby each remaining edge of each sheet of foil extends beyond the corresponding adjacent edge of said sheet of dielectric;
• and
• clip means, piercing one of the extended sheets of foil in said one capacitor pack and one of the sheets of foil in said another capacitor pack, for electrically connecting one of the sheets of foil in said first capacitor pack with one of the sheets of foil in said another capacitor.

Apparatus, comprising:

• a. a first sheet of thin metallic foil defining two edges which are generally parallel to one another and separated by a first distance;
• b. a first sheet of dielectric film defining two lateral edges which are separated by a distance which is generally equal to said first distance, one of said two lateral edges of said first sheet of film being offset from one of the two edges of said first sheet of foil, whereby the other edge of said first sheet of foil extends beyond the other edge of said first sheet of film;
• c. a second sheet of thin metallic foil defining two parallel edges which are separated by distance generally equal to said first distance, one of said two parallel edges of said second sheet of foil being offset from and disposed upon said one edge of said first sheet of film, whereby the other edge of said second sheet of foil extends beyond said other edge of said first sheet of film;
• d. a third sheet of thin metallic foil aligned to said first sheet of foil and defining two spaced apart edges which are separated by said first distance with one of said two spaced apart edges aligned with said one edge of said first sheet of foil;
• e. a second sheet of dielectric film aligned to said first sheet of film and defining two lateral edges which are separated by said first distance, one of said two lateral edges of said second sheet of film being offset from said one spaced apart edge on said third sheet of foil;
• f. a fourth sheet of thin metallic foil defining two parallel edges which are separated by a distance generally equal to said first distance, one of said two parallel edges of said fourth sheet of foil aligned to said third sheet of foil and being offset from said one parallel edge of said second sheet of film, whereby the other edge of said fourth sheet of foil extends beyond the other edge of said second sheet of film;
• g. spacing means, disposed between said second sheet of foil and said third sheet of oil, for spacing said second sheet of foil from said third sheet of foil;
• h. mechanical means, for holding said first sheet of foil in contact with said third sheet of foil;
• wherein said mechanical means comprises:
• i. a first metal member defining a generally flat plane and a plurality of teeth which are disposed generally perpendicular to the plane of said first member and which are adapted to pierce said first sheet of foil and said third sheet of foil;
• j. a second metal member defining a generally flat plane and a plurality of apertures adapted to receive said teeth;
• and
• k. means, connecting said first and said second metal members, for inelastically holding at least one of said teeth in alignment with one of said apertures.
