摘要:
The present invention relates to electrical conductors for electrical transmission and distribution with pre-stress conditioning of the strength member so that the conductive materials of aluminum, aluminum alloys, copper, copper alloys, or copper micro-alloys are mostly tension free or under compressive stress in the conductor, while the strength member is under tensile stress prior to conductor stringing, resulting in a lower thermal knee point in the conductor.

A bending coaxial electrical connector is disclosed which comprises a center terminal, a dielectric body and an outer conductor wherein the cover section of the outer conductor is provided with a protrusion projecting to the tubular section by means of which a corresponding bump is stamped out from the dielectric body which is then pressed against a center conductor of the coaxial cable disposed on the connecting section so as to form a secure connection between the center conductor of the coaxial cable and the connecting section of the center terminal of the coaxial electrical connector. The electrical connector in the present invention is advantageous in that the various structures described above can firmly maintain the center conductor at a predetermined position on the center terminal, the consistency and stability of the characteristic impedance of the connection is therefore achieved.

A method for making a coaxial cable including an inner conductor, an outer conductor, and a dielectric material layer therebetween may include forming the inner conductor by at least forming a bimetallic strip into a tubular bimetallic layer having a pair of longitudinal edge portions at a longitudinal seam. The bimetallic strip may include an inner metal layer and an outer metal layer bonded thereto and coextensive therewith. Each of the longitudinal edge portions may be folded over. The method may also include forming a welded joint between adjacent portions of the folded over longitudinal edge portions and defining surplus material at the welded joint. The method may further include removing the surplus material at the welded joint and forming the dielectric material layer surrounding the inner conductor. The method may also include forming the outer conductor surrounding the dielectric material layer.

Coaxial cable shielding. In one example embodiment, a coaxial cable includes a center conductor, a dielectric, a tape, and a jacket. The tape defines first and second edge portions that each borders an interior portion. The thickness of the first edge portion is less than the thickness of the interior portion. The dielectric surrounds the center conductor. The tape is wrapped around the dielectric such that the first edge portion overlaps with the second edge portion. The jacket surrounds the tape.
