A wire harness that includes a connector in which a connection end of a single-core wire electrical cable and a connection end of a twisted wire electrical cable are welded to each other and are covered by a heat shrinkable tube, wherein the connector includes a separator between the connection end of the twisted wire electrical cable and the heat shrinkable tube, the separator being made of metal and being configured to separate the connection end of the twisted wire electrical cable from the heat shrinkable tube.

A wire harness assembly including a first, second, and third shielded wire cable, each having a core conductor surrounded by a shield conductor which is surrounded by a insulative jacket. Portions of the core conductors are sonically welded to one another. The assembly also includes a flexible insulative layer wrapped about the sonically welded core portions, a flexible conductive layer wrapped about the flexible insulative layer and exposed shield portions, and a section of heat shrink tubing in which the flexible conductive layer and portions of the insulative jackets are enclosed. The assembly further including an insulative housing having a longitudinal cavity extending therethrough in which the section of heat shrink tubing, the flexible conductive layer, and portions of the insulative jackets are disposed.

According to one aspect of the disclosure, an end cap for a heat shrink kit having a heat shrink tubing is provided. The end cap includes a tubing portion sized to be inserted into the heat shrink tubing and an end portion configured to prevent at least a portion of a flame from reaching the heat shrink tubing.

Various implementations include a method of connecting wire to conductive fabric. The method includes (1) providing a conductive fabric having a main portion and a protrusion extending along a protrusion central axis from the main portion, the protrusion having a distal edge spaced apart from the main portion along the central axis and side edges that extend between the main portion and the distal edge; (2) placing a wire along at least a portion of the protrusion, the wire having a first end and a second end opposite the first end; (3) folding the distal edge of the protrusion over the wire one or more times to form a folded portion of the protrusion; and (4) after folding the distal edge, securing the folded portion of the protrusion with a securing device.

A method of heat shrinking a protective sleeve onto an electrical connection includes an initial step of providing an electrical connection, such as between an electrical wire and an electrical termination device, and a protective sleeve having an inner surface and an outer surface. The inner surface of the protective sleeve has an adhesive material applied thereto and is disposed about the electrical connection. Thermal energy is applied to the outer surface of the protective sleeve so as to increase the temperature thereof. Either before, at the same time, or after this step, the temperature of some or all of the electrical connection disposed within the protective sleeve is increased, such as by induction heating. As a result, the protective sleeve shrinks onto the electrical connection, and the adhesive material forms a tight bond between the protective sleeve and the electrical connection.

A method for forming an electrical connection in a pipe for transporting a fluid. The pipe comprises an internal hollow tube and a heating layer comprising first fibers made of carbon. There are performed a groove-formation step in which a groove is formed in the heating layer, an interface-preparation step in which a junction layer is placed on the heating layer of the groove, and a placement step in which a connection strip comprising second fibers formed of a second electrically conducting material is wound on the junction layer.

A heat-shrinkable protective element having at least one protective layer is obtained from a polymeric composition having a polymer material, where the polymeric composition additionally has an electrically conducting filler having a BET specific surface of at least 100 m.sup.2/g according to Standard ASTM D 6556.

An electronic device has structures that are assembled using attachment structures. The attachment structures change shape to help join the electronic device structures together. Structures that may be joined together can include electronic device housing structures, display structures, internal device components, electrical components, and other portions of an electronic device. The attachment structures can include heat-activated attachment structures, structures that are activated using other types of applied energy, and structures that change shape due the application of chemicals or other treatments.

A plate shaped heater for heating a heat shrink tube on a cable includes a housing, multiple heating tubes arranged within the housing, and a heating wire arranged in the multiple heating tubes. The housing defines opposite ends in its longitudinal direction. The heating tubes extend along a transverse direction of the housing and are arranged in a row along the longitudinal direction of the housing. An arrangement density of the heating tubes in two end regions proximate two ends of the housing is greater than an arrangement density of the heating tubes in a middle region between the two end regions of the housing.
