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.

Abstract: A system for sealing an electrical terminal which includes a device for sealing a plurality of electrical wires to a wire attachment portion of an electrical terminal. The device includes a shrinkable tubing which is placed over the plurality of electrical wires such that one end thereof extends over the wire attachment portion of the electrical terminal. A sealant/adhesive is placed within the heat shrink tubing and has a first portion proximate to the edge of heat shrink tubing. The sealant/adhesive has a strip of high viscosity sealant/adhesive proximate a strip of low viscosity sealant/adhesive. Upon the application of heat to the device after installation of the device over the electrical terminal, the shrinkable tubing starts to recover, the first portion of the sealant/adhesive flows and seals free ends of the plurality of electrical wires to seal the free ends of the electrical wires.

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.

Abstract: A system and device for sealing a plurality of electrical wires to a wire attachment portion of an electrical terminal, wherein a shrinkable tubing is placed over the plurality of electrical wires such that one end thereof extends over the wire attachment portion of the electrical terminal. A band of the high viscosity sealant/adhesive is placed within the heat shrink tubing adjacent to the edge of heat shrink tubing. A band of the low viscosity sealant/adhesive is placed within the heat shrink tubing. Upon the application of heat to the device, the shrinkable tubing starts to recover, the high viscosity sealant/adhesive seals the edge of the shrinkable tubing and the low-viscosity sealant/adhesive flows across and through the plurality of electrical wires to create a seal. The high viscosity sealant/adhesive prevents flow of the low-viscosity sealant/adhesive from contaminating the electrical terminal.
