Patent number: 11843232Abstract: A sealing assembly for sealing a bundle of wires includes a first sheet formed of a sealant material, a second sheet disposed above the first sheet, and a third sheet disposed above the second sheet formed of the sealant material. The second sheet includes a thermally conductive material. When the bundle of wires is overlaid on the assembly in a first direction, and the assembly is wrapped in a second direction that is generally perpendicular to the first to thereby surround the wires, the second sheet facilitates enhanced thermal energy distribution of applied heat throughout the assembly to thereby more uniformly melt the sealant material and thereby fill voids between the wires.Type: GrantFiled: December 20, 2021Date of Patent: December 12, 2023Inventors: Vijay Daga, Jaydip Das, Kavitha Bharadwaj, Ting Gao, Quentin Francis Polosky, Henry Paul S.
