摘要： An RF plenum cable has an annular outer conductor and a coaxial inner conductor. Disposed between the inner and outer conductors is a dielectric spine which includes a sleeve that wraps around the inner conductor, and a plurality of circumferentially spaced ribs that project outwardly from an outer surface of the sleeve. Each of the ribs is defined by a tapered configuration having a first thickness at a first end portion coupled to the sleeve, and a second thickness at a second end portion coupled to an inner surface of the outer conductor, in which the first thickness is less than the second thickness. The dielectric spine may be formed of a plastic having a dielectric constant and loss tangent that, combined with the design of the dielectric spine and the dimensions of the inner and outer conductor, allows for a reduced insertion loss at high frequencies (e.g., 6 GHz).

摘要： Cost reduction in a multicore cable is realized by reduction in the frequency of damaging a coaxial cable upon removal of a covering layer. A multicore cable 10 includes multiple coaxial cables 11 arranged in parallel, and ground members 15, 16 conductively connected with the coaxial cables 11. Each coaxial cable includes an internal conductor 11a, an internal insulating layer 11b covering an outer peripheral surface of the internal conductor 11a, an external conductor 11c covering an outer peripheral surface of the internal insulating layer 11b, a covering layer 11d covering an outer peripheral surface of the external conductor 11c, a removed portion 11e formed in such a manner that part of the covering layer 11d in a circumferential direction is removed such that the external conductor 11c is exposed, and a conductive member 21 filling the removed portion 11e. The ground member 15 is conductively connected with the conductive member 21 filling the removed portion 11e.

摘要： A method of forming a coaxial wire that includes providing a sacrificial trace structure using an additive forming method, the sacrificial trace structure having a geometry for the coaxial wire, and forming a continuous seed metal layer on the sacrificial trace structure. The sacrificial trace structure may be removed and a first interconnect metal layer may be formed on the continuous seed layer. An electrically insulative layer may then be formed on the first interconnect metal layer, and a second interconnect metal layer is formed on the electrically insulative layer. Thereafter, a dielectric material is formed on the second interconnect metal layer to encapsulate a majority of an assembly of the first interconnect metal layer, electrically insulative layer and second interconnect metal layer that provides said coaxial wire. Ends of the coaxial wire may be exposed through opposing surfaces of the dielectric material to provide that the coaxial wire extends through that dielectric material.

摘要： A method for attaching a prefabricated miniature coaxial wire to a first electrical connection point, the prefabricated miniature coaxial wire having an electrically conductive core disposed within an electrical insulation layer disposed within an electrically conductive shield layer, includes attaching an exposed portion of the electrically conductive core at a distal end of the prefabricated miniature coaxial wire to the first electrical connection point, thereby establishing electrical conductivity between the electrically conductive core and the first electrical connection point, depositing a layer of electrically insulating material onto the exposed portion of the electrically conductive core such that the exposed portion of the electrically conductive core and the first electrical connection point is encased in the layer of electrically insulating material, and connecting the electrically conductive shield layer to a second electrical connection point using a connector formed from an electrically conductive material.

摘要： A dual axial cable includes first and second signal conductors, a shield, and a drain wire. The first and second signal conductors transmit a differential signal. The shield is spirally wrapped around the first and second conductors, and causes a resonant characteristic of the dual axial cable. The drain wire provides a return path for the differential signal in the dual axial cable. The drain wire is roughened to a specific amount of roughness, which reduces signal loss at resonant frequencies of the resonant characteristic caused by the shield.

摘要： A method of manufacturing an improved overhead or underground telephone lead-in cable for transmission services VVDL (voice, video, data and lead-in) that permits the connection of the users to the public telephone system with a high speed digital service link, besides the analog services required. The cable has at least one or a plurality of transmission circuits. One of the transmission circuit is formed by two metal conductor elements cooperating in turn to self-support the cable or a conventional type of impregnated fibers or kevlar tape. The second circuit which is formed by a stranded pair of conductors is impregnated with a swelling powder preventing moisture penetration.
