Systems and methods presented herein provide for elastomeric and flexible cables. In one embodiment, the cables are configured with elastomeric cabling and circuitry. For example, a flexible circuit line (or lines) may be wrapped about an extruded elastomeric substrate (e.g., a polymer). Integrated circuits (e.g., sensors, accelerometers, light emitting diodes, controllers, microprocessors, etc.) may be disposed at various points along the circuit line(s). The cable may then be wrapped with a Polytetrafluoroethylene (PTFE) tape than can be heated to shrink about the cable for protection of the underlying circuitry. Then, the cable may be surrounded with a layer of polymer and extruded to form an elastomeric and flexible cable.

A dual axial cable includes first and second signal conductors and a shield. The first and second signal conductors transmit a differential signal. The shield includes a foil wrap spirally wrapped around the first and second conductors to form a plurality of foil wrap sections. Each of the foil wrap sections overlaps an adjacent foil wrap section. The periodicity of a pitch of each of the overlaps varies along a length of the dual axial cable.

A composite cable includes a signal transmission cable including a pair of signal lines being arranged parallel to each other in a cable longitudinal direction and contacting to each other and a shield layer covering the pair of signal lines together, a pair of power supply lines being arranged contacting to each other and contacting to the shield layer, a collective braided shield covering around a cable core composed of the signal transmission cable and the pair of power supply lines collectively, a sheath covering around the collective braided shield. The collective braided shield is configured closely contacting to the shield layer in accordance with an outer shape of the shield layer.

A data cable is provided herewith, along with related methods. The disclosed data cables may meet the requirements for a UL 2196 flame test, including subsequent hose stream test. The disclosed data cables include two or more pairs of conductors wrapped with a flame-retardant tape and surrounded by low smoke zero halogen (LSZH) thermoset insulation. A shield may surround the conductor pairs and a non-halogen flame retardant polyolefin may surround the shield. In certain embodiments, the pairs of conductors present in the cable may have different lay lengths.

A shielded twisted pair cable includes a twisted pair wire including two insulated wires that are twisted together, and a shield configured to cover the twisted pair wire. Each of the two insulated wires includes a conductor, and an insulator covering the conductor. The shield includes a first shield, a second shield, and a third shield in this order from a position closest to the twisted pair wire. The first shield includes a first resin tape with a metal foil, spirally wound around the twisted pair wire, the second shield includes a braided conductor, and the third shield includes a second resin tape with a metal foil. The metal foil of the first resin tape with the metal foil makes contact with the braided conductor, and the braided conductor makes contact with the metal foil of the second resin tape with the metal foil.

A circuit board assembly has a circuit board and a high-speed cable. The high-speed cable has two signal lines, a ground conductor, an impedance-reducing conductor, and a covering material. The signal lines, the ground conductor, and the impedance-reducing conductor are mounted through the entire high-speed cable. The covering material wraps the signal lines, the ground conductor, and the impedance-reducing conductor, and has a conductive layer and an isolation layer as an inner layer and an outer layer respectively. The conductive layer has multiple loops electrically connected to the ground conductor and the impedance-reducing conductor. Thus, the impedance in the covering material, the ground conductor, and the impedance-reducing conductor is decreased, which prevents from attenuating the signal intensity during transmission at high frequency.

A cable for power transmission or communication has a core unit having at least one conductor and an insulating layer surrounding each conductor. A first shielding layer surrounds the core unit and is formed of a polymer-carbon composite in which carbon-based particles are dispersed in a matrix of thermosetting polymer material, the first shielding layer having an electrical resistance of 10 Ω.Math.m or less. A metal-based second shielding layer surrounds the first shielding layer.

Cable foil tape having random or pseudo-random patterns or long pattern lengths of discontinuous metallic shapes and a method for manufacturing such patterned foil tape are provided. In some embodiments, a laser ablation system is used to selectively remove regions or paths in a metallic layer of a foil tape to produce random distributions of randomized shapes, or pseudo-random patterns or long pattern lengths of discontinuous shapes in the metal layer. In some embodiments, the foil tape is double-sided, having a metallic layer on each side of the foil tape, and the laser ablation system is capable of ablating nonconductive pathways into the metallic layer on both sides of the foil tape.
