A multicore cable includes a plurality of covered wires having a lubricant powder provided on surfaces thereof, and an outer sheath layer covering outer surfaces of the plurality of covered wires. The outer surfaces of the plurality of covered wires, and the outer sheath layer, make contact with one another via the lubricant powder.

The present invention discloses a flat cable, which comprises signal unit sets and the insulating layer which wraps and fixes the signal unit set. The signal unit set is formed by at least two signals units arranged substantially on the same plane at an interval or side by side. The left and right sides of the signal unit set are directly wrapped by insulating layers. The insulating layer is formed by splicing and bonding at least one insulating film, and the splicing points at two ends of the insulating film are located on the upper side or the lower side of the signal unit set. In the flat cable of the present invention, the length of the overlapping portion can be set as required, effectively preventing the phenomenon such as insulating film tear and short circuit caused by insulating film tear.

A flat data transmission cable includes a plurality of juxtaposed wires, a plastic layer enclosing on the wires integrally and a metallic layer formed by a metal material belt arranged on an outer side of the plastic layer in a spiral winding way, each wire has a conductor. The metallic layer has at least an aluminum foil layer and a bonding layer arranged on the side of the aluminum foil layer facing to the plastic layer, the metallic layer is bonded to the outer side of the plastic layer by the bonding layer.

An electrical cable includes a first conductor assembly having a first inner conductor and a first insulator engaging and surrounding a surface of the first inner conductor and a second conductor assembly having a second inner conductor and a second insulator engaging and surrounding a surface of the second inner conductor. The electrical cable includes a non-conductive buffer layer surrounding the conductor assemblies having an inner surface engaging the insulators and a conductive shield layer engaging and surrounding an outer surface of the non-conductive buffer layer and providing electrical shielding for the conductor assemblies. An outer jacket engages and surrounds the conductive shield layer.

A flexible flat cable according to various embodiments of the disclosure may include a first insulation layer having a plate shape, a first conductive pattern disposed on the first insulation layer, a second conductive pattern disposed on the first insulation layer to be spaced apart from the first conductive pattern at a predetermined interval, a second insulation layer covering at least a portion of the first conductive pattern and disposed on the first insulation layer to cover the first conductive pattern, a first shield member including a first shield layer disposed on the first insulation layer and the second insulation layer to cover the first conductive pattern and the second conductive pattern, and a second shield layer disposed on the first shield layer to cover the first shield layer, and a third insulation layer surrounding the first shield layer such that at least a portion of the first shield layer of the first shield member, which is exposed between the first insulation layer and the second shield layer of the first shield member is covered.

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 shielded electrical cable includes a conductor set and two generally parallel shielding films disposed around the conductor set. The conductor set includes one or more substantially parallel longitudinal insulated conductors. The shielding films include a parallel portion wherein the shielding films are substantially parallel. The parallel portion is configured to electrically isolate the conductor set.

A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is 1, the center-to-center spacing of the insulated conductors of the second conductor set is 2, and 1/2 is greater than 0.7.

A shielded electrical cable includes one or more conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable. Each conductor set has one or more conductors having a size no greater than 24 AWG and each conductor set has an insertion loss of less than about 20 dB/meter over a frequency range of 0 to 20 GHz. First and second shielding films are disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor.

A data cable for high-speed data transmission at signal frequencies of >10 GHz includes at least one core pair which is surrounded by a film-shaped pair shield having an inner shielding film and an outer shielding film which, are in electrical contact with one another and in which the inner shielding film is wound around the core pair. By virtue of this measure, an undesired resonance effect is avoided which, in previously wound pair shields, has not allowed use for relatively high signal frequencies. At the same time, an undesired common-mode signal, which would occur in the case of a longitudinally folded shielding film, is thus suppressed.
