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.

A dual-core connector
The present invention relates to a dual-core connector, which includes a first single-core plug and a second single-core plug. The first single-core plug and the second single-core plug are detachably connected by a first locking member. The beneficial effects of the present invention are as follows: Since the dual-core plugs in the dual-core connector are two independent single-core plugs before combination, it is not only beneficial to pass through a smaller space, but also the lengths of the respective connecting cables can be determined as needed, and the flexibility of a single cable is also better. Therefore, it is beneficial to the plugging operation of the plug when the connector is plugged and unplugged, and it is also very convenient to replace the plug, and the volume can also be reduced.
