Patent ID: 8395879

Claim:
A bundled capacitor with a plurality of individual rolled sandwich like connected capacitors, wherein each individual rolled sandwich like connected capacitor of the plurality of individual rolled sandwich like connected capacitors provides an individual capacitance value, wherein the bundled capacitor comprises: a. a housing comprising: i. a body with an interior and an exterior; ii. a first integral end connected to the body; and iii. a hermetically sealable deformable cap connected to the body opposite the first integral end, wherein the hermetically sealable deformable cap comprises an expandable body and a lip integral with the expandable body for non-removable engagement with the body; b. a central common terminal disposed through the hermetically sealable deformable cap; c. a plurality of auxiliary terminals concentrically disposed around the central common terminal; d. an interrupter inner part disposed on the expandable body and extending toward the body of the housing, wherein the interrupter inner part engages each auxiliary terminal of the plurality of auxiliary terminals and the central common terminal; e. an interrupter outer part connected with the hermetically sealable deformable cap; f. the plurality of individual rolled sandwich like connected capacitors disposed within the housing, wherein each individual rolled sandwich like connected capacitor of the plurality of individual rolled sandwich like connected capacitors comprises: i. the individual capacitance value; ii. a positive terminal in electrical communication with one of the plurality of auxiliary terminals; and iii. a negative terminal, wherein the negative terminals are electrically connected together to form an insulated collective connection; g. at least one thermal fuse disposed within the housing, wherein the at least one thermal fuse is in electrical communication with the insulated collective connection and with the central common terminal; h. an insulating and flame retarding curing resin disposed around the plurality of individual rolled sandwich like connected capacitors for rigidly supporting the plurality of individual rolled sandwich like connected capacitors; i. first portion of an insulating layer disposed between the insulating and flame retarding curing resin and the interior of the body, wherein the first portion of the insulating layer is disposed on the interior of the body and runs from the first integral end and terminates between the hermetically sealable deformable cap and the body, and wherein a second portion of the insulating layer is disposed on top of the insulating and flame retarding curing resin; and j. an expansion chamber formed between the second portion of the insulating layer and the interrupter outer part, wherein the expansion chamber enables the hermetically sealable deformable cap to deform when at least one of the individual rolled sandwich like connected capacitors overheats in the bundled capacitor.
