An electric connector is disposed between a connection terminal of a first device and a connection terminal of a second device, and electrically connects these connection terminals. The electric connector includes a resin layer, and a plurality of metal wires extending through the resin layer in a thickness direction, and having a rectangular shape on surfaces to be connected to the connection terminals. At least first sides of the rectangular shapes of the metal wires are arranged at equal intervals along the same direction. The length of short sides of the rectangular shapes are less than 5 m.

A wire harness includes an electric wire having flexibility, and a flexible tubular body that has no slit on an entire region from one end to the other end of the tubular body and accommodates the electric wire. A route regulation portion for restricting the tubular body to a desired route shape is provided in a predetermined range of the tubular body in a tube axis direction of the tubular body in a state where the electric wire is accommodated in the tubular body. The route regulation portion has an injection hole that is provided in a peripheral wall of the tubular body so as to pass through the peripheral wall, and a cured portion that is injected through the injection hole and is cured in the tubular body.

A grommet assembly includes a wire harness and a grommet including a hollow channel configured to receive the wire harness therein. At least one rib extends inwards from and substantially annularly about the interior surface of the hollow channel. At least one port configured to fluidly couple the hollow channel with an exterior environment is defined by the grommet. Material is injected into the channel through the port to secure the grommet relative to the wire harness. The material injected into the channel flows through interstices located between adjacent wires that define the wire harness so as to encapsulate the wires. The injected material also flows into other voids and openings located within the hollow channel. Upon setting, the injected material is configured to prevent movement of the grommet relative to the wire harness and to prevent the passage of contaminants through the grommet assembly.

A method of fabricating a composite conductive film is provided. The method includes providing, as a matrix, a layer of cross-linkable polymer while the cross-linkable polymer is in a substantially noncross-linked state. The method further includes introducing a plurality of inorganic nanowires onto a surface of the layer of cross-linkable polymer and embedding at least some of the plurality of inorganic nanowires into the layer of cross-linkable polymer to form an inorganic mesh within the layer of cross-linkable polymer, thereby forming the composite conductive film. The method further includes cross-linking the cross-linkable polymer within at least a surface portion of the composite conductive film, wherein following the cross-linking, the cross-linkable polymer within at least the surface portion of the composite conductive film is in a cross-linked state.

A wiring harness assembly includes a plurality of separated conductors formed of an electrically conductive material, a substrate formed of a dielectric material encasing the plurality of separated conductors, a location feature integrally formed with the substrate and an opening defined in the substrate having a predetermined size and shape. A section of the plurality of separated conductors is exposed within the opening. The opening is precisely located relative to the location feature.

A method for producing an electrical conductor may include cutting an electrically conductive round wire composed of copper to a predefined desired length and plastically forming the round wire, in at least one forming section, into a predefined desired shape.

An aluminum alloy wire composed of an aluminum alloy, wherein the aluminum alloy contains more than or equal to 0.03 mass % and less than or equal to 1.5 mass % of Mg, more than or equal to 0.02 mass % and less than or equal to 2.0 mass % of Si, and a remainder of Al and an inevitable impurity, Mg/Si being more than or equal to 0.5 and less than or equal to 3.5 in mass ratio, and the aluminum alloy wire has a dynamic friction coefficient of less than or equal to 0.8.

A cable hose suitable for welding or cutting systems includes tubing, one or more conductors, and an annular electromagnetic interference (EMI) shield. The EMI shield is disposed radially interiorly of at least a portion of the tubing and radially exteriorly of the one or more conductors. Thus, the EMI shield: (1) prevents EMI emanating from the one or more conductors from exiting the cable hose radially; and (2) conducts current between components of a welding or cutting system.

Disclosed herein is a patterning formation method including printing on a film base, a manufacturing method of an electrical device using the same, and a vehicular electrical device. More particularly, disclosed herein is a patterning formation method including arranging a poly cyclohexylene dimethylene terephthalate (PCT) film as a base film or as an upper part film such as a coverlay film, and patterning a material such as a metal by a printing method or connecting printing electronic technologies on at least a part of the PCT film. Also disclosed herein is a manufacturing method of an electrical device using the same and a vehicular electrical device.

An example communications cable includes a core carrier disposed within a cable jacket. A pair of twisted conductors are partially disposed within the core carrier. A portion of the core carrier separates a first conductor in the pair of twisted conductors from a second conductor in the pair of twisted conductors.
