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.

A conductor arrangement for an electrical energy or data transmission connection includes at least one conductor portion comprising a flexible internal conductor and a thermoplastic hard plastic sheath surrounding the flexible internal conductor. The thermoplastic hard plastic sheath is transformable into a formable state when heated to a threshold temperature defined at a specific softening point, and the thermoplastic hard plastic sheath hardens into a formed state when cooled.

A flex flat cable (FFC) structure includes metallic transmission wires arranged in parallel, first insulating jackets, and second insulating jacket. The metallic transmission wires includes one or more power wires and signal wires. The power wire is configured to transmit power. The signal wires are configured to transmit a data signal. Each of first insulating jackets encloses one of metallic transmission wires. The second insulating jacket surrounds the first insulating jackets. An embossment pattern is arranged on an external surface of the second insulating jacket. The embossment pattern includes meander lines in a top-view direction and in an extending direction for the metallic transmission wires. The meander lines are not arranged parallel.

An electrical conduction path includes a main cable that has a multi-core cable obtained by enveloping a plurality of electric wires together with a sheath, and a plurality of branch cables obtained by dividing the electric wires of the multi-core cable into a plurality of parts, wherein connection portions are provided, in each of which an electric wire of the multi-core cable and an electric wire of a branch cable are electrically connected to each other. According to this configuration, it is possible to reduce the length of the expensive multi-core cable compared to a case where the electric wires of a multi-core cable are used over the entire length of a cable including the branch cables, thus achieving cost reduction.

A communications cable is described. The communications cable can include a cable jacket, a separator structure that defines one or more channels for receiving at least one communications medium, and an insulator that surrounds the communications medium. The cable jacket can include one or more corrugations on at least one of its interior or exterior surfaces. The separator can also include one or more grooves on at least a portion of its surface. The insulator can also include one or more indentations on at least one of its interior or exterior surfaces. The corrugations, grooves, and indentations can extend along the longitudinal length of the cable and define one or more air channels for forwarding and circulating air through or on the surface the cable. The circulation of air in the cable can reduce the temperature of the cable and increase the quality of the signal transmitted through the cable.

An electric cable for supplying power to aircrafts, rail vehicles, motor vehicles, ships or other devices is a single or multi-conductor cable and includes one or more current conductors with at least one insulation. A single or multi-layer outer casing is distributed over the periphery and is associated with the outwardly protruding reinforcing elements. The reinforcing elements are in the form of cooling ribs protruding preferably over the entire periphery of the cable and enable the surface of the cable to be increased and as a result, improve heat dissipation. The projecting reinforcing elements considerably reduce the risk of burning when the current conductors heat up and also protect the cable against abrasion. The invention also relates to a plug for the electric cable.

A wire harness includes: a tubular outer member; and a conductive path which is inserted in and protected by the outer member. The conductive path includes a vibration suppressing portion which reduces a movable space of the conductive path at a prescribed position inside the outer member to suppress shaking of the conductive path. The vibration suppressing portion is formed by a partially increased thickness portion of a covering of the conductive path.

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.

A wire harness including a round electric wire and a flat electric wire. The round electric wire includes a round conductor made of a predetermined metal and having a round cross-sectional shape and a first coating portion. The flat electric wire includes a flat conductor having a flat cross-sectional shape and a second coating portion. The round electric wire and the flat electric wire are arranged in parallel. The round conductor has a diameter equal to or less than a predetermined reference value. The flat conductor has a thickness equal to or less than the reference value and a width in which ensure cross-sectional area of the flat conductor more than area of a circle having a diameter equal to the reference value.

A communication cable includes a cable core including a plurality of pairs of wires, each of the pairs of wires being formed by spirally twisting two wires including conductors covered with an insulator, and an external jacket configured to cover an outer side of the cable core, where the external jacket includes a plurality of support arms to prevent contact between the cable core and an inner surface of the external jacket and to secure a separation space in a radial direction, the plurality of support arms being integrally formed with the external jacket, and each of the plurality of support arms including a connection part connected to the inner surface of the external jacket and a support part having an increased width at an end portion of the connection part to support the cable core, thereby enabling the communication cable to satisfy a standard of Cat.6A or higher.
