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.

Assembly and method for sealing a bundle of wires

A sealing device and method for sealing an electrical terminal. The sealing device includes a heat shrinkable tubing having an inner wall. A first sealant/adhesive is configured to cooperate with the heat shrinkable tubing. The first sealant/adhesive has a first sealant/adhesive first surface and an oppositely facing first sealant/adhesive second surface. The second surface of the first sealant/adhesive is bonded to the inner wall of the heat shrinkable tubing. A second sealant/adhesive is configured to cooperate with free ends of electrical conductors which are in electrical engagement with the electrical terminal. The second sealant/adhesive has a second sealant/adhesive first surface and an oppositely facing second sealant/adhesive second surface. The second sealant/adhesive first surface is provided in engagement with the electrical conductors. The second sealant/adhesive second surface is provided in engagement and bonded with the first sealant/adhesive first surface.

System and method for sealing electrical terminals

A structure for creating a sealed wire bundle includes a first adhesive material in the form of a circular or semi-circular shape. The first adhesive material has a first outer wall with first spoke arms extending inward from the first outer wall. The first adhesive material has a first viscosity. First wire receiving spaces are provided between the first spoke arms. Wires are positioned in the first wire receiving spaces. As heat is applied to the adhesive structure, the adhesive structure flows to fill voids between the plurality of wires to thereby seal the wires.

A method for sealing a bundle of wires includes providing an adhesive material having a viscosity of less than about 300 Pa&#xb7;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.

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.

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.

Apparatus and methods for sealing electrical connections

A system and device for sealing a plurality of electrical wires to a wire attachment portion of an electrical terminal, wherein the device further includes a first piece of heat shrink tubing having a predetermined length, wherein the first piece of heat shrink tubing has been placed over the plurality of electrical wires such that one end thereof extends over the wire attachment portion of the electrical terminal; a second piece of heat shrink tubing having a predetermined length, wherein the second piece of heat shrink tubing has a smaller diameter than the first piece of heat shrink tubing, and wherein the second piece of heat shrink tubing is placed partially inside the end of the first piece of heat shrink tubing that extends over the wire attachment portion of the electrical terminal; and a band of adhesive placed within the first piece of heat shrink tubing adjacent to the second piece of heat shrink tubing.

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.

A tube assembly includes glass fiber, a heat-recovered heat recoverable tube surrounding at least a portion of the glass fiber, an adhesive having an adhesive composition comprising a reactive polyethylene and a reactive propylene copolymer. The adhesive adhesively couples the heat-recovered heat recoverable tube to the glass fiber. The adhesive composition includes a reactive polyethylene, such as, a maleic anhydride modified linear low density polyethylene resin, and a reactive propylene copolymer, such as, a maleic anhydride grafted polypropylene copolymer. The adhesive composition is capable of adhering to glass fiber with an axial load of 5 N at 70&#xb0; C. for a period of at least 60 seconds.
