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 cable support for receiving and supporting a cable that includes a plurality of conductors extending along the length of the cable and arranged along the width of the cable, includes: a cane-shaped base having a substantially straight base portion and a curved base portion. The cane-shaped base includes a cable-side major surface and an opposing back-side major surface. At least a first portion of the back-side major surface in the curved base portion faces a second portion of the back-side major surface in the straight base portion. A plurality of discrete spaced apart side walls are disposed on the cable-side major surface along each longitudinal edge of the cane-shaped base. At least one side wall is disposed on the straight base portion and at least one side wall is disposed on the curved base portion.

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 flexible flat cable for transmitting high-frequency signals includes an inner flat cable and a pair of shielding composite layers, which are divided into a main section, two connecting sections, and two sealing sections. The inner flat cable is disposed in the main section, and includes a plurality of conductors, an insulated glue layer, a pair of insulated partition layers and a pair of metallic shielding layers. The pair of insulated partition layers are disposed at two sides of the conductors and are affixed oppositely. The pair of metallic shielding layers are disposed at outer sides of the pair of insulated partition layers. Each shielding composite layer has a width larger than a width of the inner flat cable, and includes an outer shielding layer and a conductive glue layer having one part affixed to the inner flat cable and another part affixed to each other.

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.

The present invention relates to a high speed transmission cable that includes a first conductor set, a dielectric film at least partially concentrically disposed around the first conductor set and a pinched portion forming an insulating envelope around the first conductor set. The dielectric film includes a base layer having a plurality of first protrusions formed on a first major surface of the base layer, wherein the dielectric film is disposed such that the base layer is partially concentric with the conductor set and wherein a portion of the first protrusions is disposed between the first conductor set and the base layer in a region where the base layer is concentric with the first conductor set.

Further, a length (L1) of the conductive wires is equal to a length of the lower film, so that an end portion of the conductive wires matches with an end portion of the lower film, the length (L1) of the conductive wires is longer than a length (L2) of the upper film, so that an exposed connection end of the conductive wires is exposed outward from an end portion of the upper film, a thermal-pressed end for pressing the air gap is formed at the end portion of the upper film by thermally pressing the end portion of the upper film so as to prevent a plating solution from entering the air gap in a plating process, and the first thermal bonding resin applied to the thermal-pressed end of the upper film and the second thermal bonding resin of the lower film are bonded to each other so as to surround a periphery of the conductive wires.
