An object of the present invention is to enable sufficient welding of multiple metal wires in at least a portion of a conductive member that is constituted by multiple metal wires. The conductive member includes multiple metal wires each including a metal strand and a metal covering layer formed around the metal strand, and a joined portion in which the metal wires are joined by melting of alloy portions of the metal covering layers, the alloy portions including the metal that forms the metal strands. The joined portion can be formed by joining the metal wires to each other by performing heating at a temperature higher than the melting point of the alloy portions of the metal covering layers, the alloy portions including the metal that forms the metal strands.

An attachment device includes a central body formed of a plastic material and defining a cavity configured to receive a temperature probe and a plurality of straps extending from the central body. Each strap of the plurality of straps is configured to secure a cable to the central body. The central body defines a wall having a first side configured to be in contact with the temperature probe and a second side in contact with a cable. This attachment device may notably be used in an electrical connection assembly having a connector, a temperature sensor disposed within the device, and at least two cables.

Systems and methods are provided for forming a cable. In one embodiment, a system for forming a cable comprises a non-driven roll station having a plurality of rolls for forming a shape of one or more strands associated with a first layer of the cable. Movement of the plurality of rolls of the non-driven roll station occurs passively during travel of the one or more strands associated with the first layer of the cable. The system further comprises a driven roll station having a plurality of rolls for forming a shape of one or more strands associated with a second layer of the cable. The plurality of rolls of the driven roll station are actively driven to effect movement and speed of the one or more strands associated with the second layer of the cable.

An overhead wire has a wire core having a main core and a plurality of auxiliary cores spirally and tightly stranded on the main core, and a conducting layer coating the wire core and having at least one aluminum wire layer. The main core and the auxiliary cores has fiber resin strands formed by fiber filament bundles permeated with resin through molding, and fiber filaments wound on and completely covering the fiber resin strands such that the fiber resin strand is isolated from the outside, and the at least one aluminum wire layer has a plurality of aluminum wires spirally and tightly stranded on the wire core.

An insulated electric wire capable of performing processing including removal of an insulation coating while having a flat portion in which a cross-section of a conductor has a flat outer shape, and a wiring harness having such an insulated electric wire are provided. The insulated electric wire has a conductor including a plurality of elemental wires, and an insulation coating covering an outer periphery of the conductor, having, in a cross-section perpendicular to the axial direction, a flat outer shape in the flat portion and a less flat outer shape in the low-flatness portion than in the flat portion in the insulated electric wire, and the insulated electric wire has an adhesive force between the conductor and the insulation coating which is smaller in the low-flatness portion than in the flat portion.

According to embodiments of the present invention, a stranded conductor is formed in which the occurrence of defects, such as strand unevenness of filaments and outward protrusion of filaments, is inhibited. According to embodiments of the present invention, a stranded conductor (1a) includes soft filaments (2a) stranded together. The soft filaments (2a) include a soft filament made of an aluminum material, disposed along a center (101), and include six soft filaments, twelve soft filaments, and eighteen soft filaments made of an aluminum material, disposed around and concentrically with the center. The filaments are softened filaments that are softened. A lay length (Pa) is from 6.2 times to 15.7 times a conductor diameter of the stranded conductor.
