  • Patent number: 11843232
    Abstract: 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.

  • Patent number: 11257612
    Abstract: A method for sealing a bundle of wires includes providing an adhesive material having a viscosity of less than about 300 Pa·s at the installation temperature. The method further includes forming a structure from the adhesive and inserting a plurality of wires into the structure. A first amount of heat is applied to the structure in a first heating operation. The first amount of heat being higher than an ambient temperature and lower than a softening temperature of the structure. Subsequently, a second amount of heat is applied in a second heating operation to the adhesive structure to thereby fully melt the adhesive structure and cause the adhesive of the structure to fill voids between the plurality of wires to thereby seal the wires. Application of the first amount of heat during the first operation to the structure facilitates improved melt uniformity of the structure during the second heating operation.

  • Patent number: 10297946
    Abstract: An electrical connection sealer includes an outer jacket and a low-viscosity sealant. The outer jacket includes a first piece of heat-shrinkable tubing. The outer jacket has a pre-sealed end and an open end opposite the pre-sealed end. The first piece of heat-shrinkable tubing at the open end is heat-recoverable and forms a cavity for insertion of an electrical connection. The low-viscosity sealant is insertable into the cavity. Upon application of heat to the electrical connection sealer with the electrical connection and the low-viscosity sealant in the cavity of the electrical connection sealer, the low-viscosity sealant flows across and through the first wires and the at least one second wire and the first piece of heat-shrinkable tubing shrinks to encapsulate the electrical connection and seal the electrical connection and the low-viscosity sealant substantially within the outer jacket.
