Capacitor assembly

A capacitor assembly comprising:

• a capacitor with a generally cylindrical outer surface, the cylindrical outer surface having a capacitor radius;
• a lower enclosure having a first recess, the first recess being generally cylindrical and having a first radius greater than the capacitor radius;
• a first annular retainer for engaging a lower portion of the cylindrical outer surface of the capacitor and the first recess, the first annular retainer having a plurality of tabs that extend radially outward from an outer diameter surface of the first annular retainer, each of the tabs having a sloped surface or a peaked surface, such that if the tabs engage the first recess, the first annular retainer is compressed against the outer cylindrical surface to retain the capacitor;
• an upper enclosure having a plurality of second recesses, each of the second recesses being generally cylindrical and having a second radius less than the capacitor radius;
• and
• a second annular retainer for engaging an upper portion of the cylindrical outer surface of the capacitor and the second recesses, the second annular retainer having a plurality of protrusions that extend upward from an upper surface of the second annular retainer in alignment with the second recesses, each of the protrusions having a slit for receiving a wedge, such that if the protrusions engage the wedge, the second annular retainer is compressed against the outer cylindrical surface to retain the capacitor.

A capacitor assembly comprising:

• a pair of capacitors, each of the capacitors having a generally cylindrical outer surface, the cylindrical outer surface having a capacitor radius;
• a lower enclosure comprising a pair of first recesses, each of the first recesses being generally cylindrical and having a first radius greater than the capacitor radius;
• a first dual annular retainer for engaging a lower portion of the cylindrical outer surfaces of the capacitors and the first recesses, the first dual annular retainer having a plurality of tabs that extend radially outward from an outer peripheral surface of the first dual annular retainer, each of the tabs having a sloped surface or a peaked surface, such that if the tabs engage the first recesses, the first dual annular retainer is compressed against the outer cylindrical surfaces to retain the pair of the capacitors;
• an upper enclosure having a plurality of second recesses, each of the second recesses being generally cylindrical and having a second radius less than the capacitor radius;
• and
• a second dual annular retainer for engaging an upper portion of the cylindrical outer surfaces of the capacitors and the second recesses, the second dual annular retainer having a plurality of protrusions that extend upward from an upper surface of the second dual annular retainer in alignment with the second recesses, each of the protrusions having a slit for receiving a wedge, such that if the protrusions engage the wedge, the second dual annular retainer is compressed against the outer cylindrical surfaces to retain the pair of the capacitors.
