A dielectric isolator for a twisted pair cable includes a body formed as an elongate strip with a top surface, bottom surface, a first side edge and a second side edge. A first slot is formed in the first side edge and extends at least half way toward the center of the isolator. A second slot is formed in the second side edge and extends at least half way toward the center of the isolator. During cable manufacturing, first and second wedges open the first and second slots. First and second twisted pairs are inserted into the first and second opened slots, respectively. Third and fourth twisted pairs reside at the top and bottom surface, respectively. The isolator has the cost and reel storage savings of a flat separator tape, while simultaneously providing the internal crosstalk performance of the isolator.

Described are cables for connecting components of computing systems. The cables improve automation and resulting performance of high frequency and/or high speed signal transmissions by providing reliable transmission paths between hardware components. An example cable includes parallel conductors and a dielectric core that secures the parallel conductors along the length using parallel channels in opposite sides of the dielectric core. An alignment structure is also formed in the dielectric core, which has a shape along the length of the cable. A cable jacket surrounds the parallel conductors and the dielectric core. The cable jacket is contoured to follow the shape of the alignment structure. The dielectric core can be formed to maintain consistent separation between the parallel channels along the length of the cable to match impedance of the parallel conductors along the length of the cable, whether the cable lays flat or bends around corners.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration.

A shield wire (P) that facilitates terminal processing is provided. This shield wire (P) includes a plurality of core wires and an inclusion (2) twisted together to form a core (3) having a cross-sectional circular shape, a drain wire (4) laterally wound around an outer periphery of the core, a shield tape (5) wound around, and a sheath (6) further disposed outside the shield tape (5). The shield tape (5) includes metal thin films (5b and 5c) on surfaces of a resin film (5a). An adhesive layer (7) is interposed between the shield tape and the sheath. The shield tape is adhesively integrated with the sheath by the adhesive layer.

In a multi-core cable in which a plurality of small-diameter cables are gathered and a periphery of these small-diameter cables is covered with a shield layer and a periphery of the shield layer is covered with a sheath, the shield layer is formed by braiding a plurality of twisted wires formed by twisting two or three wires, and a twist pitch of the wires is values from 20 to 50 times (both inclusive) an outside diameter of the twisted wire.

A shielded combined optical communication and conductor cable is provided. The cable includes a cable body having an inner surface defining a channel within the cable body. The cable includes an optical transmission element located within the channel and an electrical conducting element located within the channel. The cable includes an electromagnetic shield located within the channel and surrounding at least the electrical conducting element. The electromagnetic shield includes an elongate yarn strand or other strand material that supports a metal material that acts to limit electromagnetic fields from traversing across the electromagnetic shield. The strands may be unbraided and may be helically wrapped or longitudinally positioned within the cable body.

A data cable, which is particularly suitable for the automotive industry, is cost-effective to produce and allows high transmission frequencies into the gigahertz range. The data cable has two wire pairs which each have two wires which are surrounded by a pair shield. In addition to the pair shield, a planar or flat shielding element which does not surround the core pairs and makes contact with the two pair shields is arranged between the wires. The shielding element has, in particular, individual wires which run next to one another. Contact can advantageously be made with the pair shield in a plug region in a simple manner by way of the shielding element.
