Twin-lead cable is a two-conductor flat cable used as a balanced transmission line to carry radio frequency (RF) signals. It is constructed of two stranded copper or copper-clad steel wires, held a precise distance apart by a plastic (usually polyethylene) ribbon. The uniform spacing of the wires is the key to the cable's function as a transmission line; any abrupt changes in spacing would reflect some of the signal back toward the source. The plastic also covers and insulates the wires.
A cable connection structure
The application discloses a cable connection structure and relates to the technical field of cable connection.The cable connection structure comprises a double-core coaxial cable, a first single-core cable and a second single-core cable and a transition assembly.The double-core coaxial cable comprises two inner conductors arranged at intervals and a double-core shielding layer wrapping the two inner conductors.The first single-core cable comprises a first wire core and a first shielding layer wrapping the first wire core.The second single-core cable comprises a second wire core and a second shielding layer wrapping the second wire core.The transition assembly comprises two transition conductors arranged at intervals and a transition shell wrapping the two transition conductors.The corresponding ends of the two inner conductors are connected to the first wire core and the second wire core through the two transition conductors, and the double-core shielding layer, the first shielding layer and the second shielding layer are connected to the transition shell.The cable connection structure can realize broadband transition of the double-core coaxial cable to the two single-core cables, reduce impedance discontinuity in the transition area, and improve high-speed signal transmission performance and cable layout flexibility.

Double-core winding core rod
The utility model discloses a double-core winding core rod, which belongs to the technical field of high-speed wire rod transportation and comprises an outer core rod and an inner core rod, a plurality of first wear-resisting plates are arranged along the circumferential direction of the outer core rod at intervals, a through channel is arranged in the middle of the outer core rod, a sliding groove communicated with the through channel is arranged on the first wear-resisting plate, and a plurality of second wear-resisting plates are arranged on the inner core rod. The inner core rod is arranged in the penetrating channel in a sliding and penetrating mode, a jacking part is arranged at one end of the inner core rod, the size of the jacking part is larger than that of the penetrating channel, and a second wear-resisting plate connected with the sliding groove in a sliding mode is arranged on the end portion of the side, close to the jacking part, of the inner core rod in the circumferential direction. The second wear-resisting plate is provided with a limiting part matched with the sliding groove. According to the utility model, the gap between the inner core rod and the outer core rod is reduced, so that the head or the tail of the high-speed wire rod is prevented from being easily clamped and embedded in the gap area, and meanwhile, the inner core rod is prevented from being pulled out from the outer core rod when the coil collecting trolley is used for coil unloading.

Double-core non-independent butterfly cable forming device
The utility model relates to the technical field of cable processing, and discloses a double-core non-independent butterfly cable forming device which comprises a base, two groups of supporting columns are arranged on the upper surface of the base, rectangular grooves are formed in the supporting columns, long supporting rods are fixedly arranged in the rectangular grooves, and the long supporting rods are fixedly arranged in the rectangular grooves. The outer surface of the supporting long rod is slidably sleeved with a sliding block. According to the forming device for the double-core non-independent butterfly cable, by arranging the sliding block and the connecting spring, when the double-core non-independent butterfly cable is pulled by external force or the tension changes in the forming process, the sliding block can slide on the supporting long rod, the connecting spring can correspondingly stretch out and draw back, and the design can play a role in buffering and adjusting the tension; according to the double-core non-independent butterfly cable, the problems that the butterfly cable core is broken due to too large tension or the butterfly cable core is loosened, wound and the like due to too small tension are solved, the tension stability of the double-core non-independent butterfly cable in the forming process is guaranteed, and the forming quality and the production continuity are improved.
