A manufacturing method of a screening tape for using in an unshielded signal transmission cable without a drain wire for transmitting analog or digital signals comprises the following steps: providing an insulating substrate having a continuous flat surface; providing a continuous conductive layer; providing an adhesion layer in a discontinuous manner on the continuous flat surface of the insulating substrate or on the continuous conductive layer; bonding the continuous conductive layer and the insulating substrate through the adhesion layer to form a laminated structure comprising the insulating substrate, the adhesion layer, and the continuous conductive layer; and stretching the laminated structure in a longitudinal direction of the laminated structure to divide the conductive layer into multiple discrete conductive blocks that are mechanically and electrically isolated from each other.

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.

Data/telecommunication cables that include one or more layers of an integral, bonded electromagnetic shield are described. The shield may be configured to form an electrical ground path.

A high-speed transmission cable and a cable end connector including the same are provided. The cable end connector includes a connector body and the high-speed transmission cable that includes at least one cable assembly, at least one transmission line, and an insulating material. The at least one cable assembly includes multiple ground wires and multiple differential pairs that are arranged at fixed intervals and in parallel with each other, an insulating layer, and at least one shielding layer. Each of the differential pairs includes two signal wires that are adjacently arranged, and is located between two adjacent ones of the ground wires. The insulating layer covers the ground wires and the differential pairs. The at least one shielding layer is located at an outer side of the insulating layer. The insulating material covers the at least one cable assembly and the at least one transmission line.

An electrical plug includes a pair of electrical energy transmission contacts that are separate from one another, a plurality of signal transmission contacts that are separate from one another, and at least eight data transmission contacts that are separate from one another. An arrangement of the electrical energy transmission contacts, the signal transmission contacts, and the data transmission contacts forms a pin arrangement of the electrical plug.

Methods of design, manufacture and implementations of balanced twisted pair cables with a barrier tape or shield, with tuned attenuation, impedance, and coupling properties. A filler is included within the cable to separate the pairs and provide a support base for the shield, allowing for optimized ground plane uniformity and stability for tuned attenuation, impedance, and coupling properties. The filler orientation, shape, and size provides support for the shield such that a gap is provided between the shield and the twisted pairs with a given minimum size without increasing the maximum cable core size. The length of arms of the filler may be adjusted to fine-tune the size and shape of this gap and control air-dielectric volume and radial contact or spacing between any pair(s) and the shield, tuning electrical performance characteristics caused by non-linear effects of electromagnetic interactions at short ranges between the pairs, shield, filler, or other components.

A communications cable has a plurality of twisted pairs of insulated conductors, metal foil tape between the twisted pairs, and a cable jacket are disclosed. The metal foil tape can include a substrate, a metal layer on the substrate, and a triboelectric coating on at least the metal layer of the metal foil tape. The triboelectric coating has a charge affinity closer to a charge affinity of the insulated conductors than a charge affinity of the metal layer to prevent charge build up between the conductors and the metal foil tape.
