A kind of anti-bending heat dissipation copper-based alloy radio frequency coaxial cable

Abstract

The invention discloses a bending-resistant radiating copper-based alloy radio frequency coaxial cable. The structure of the cable from inside to outside is as follows: a center conductor, an electricmedium, an isolation layer, an intermediate layer and an outer jacket; the intermediate layer comprises shielding layers, arc extension structures and a filling layer; the shielding layer is formed by extending and arranging a plurality of hollow cylinders at intervals; the inside of each hollow cylinder is in abut joint the isolation layer, and the adjacent hollow cylinders are connected througha plurality of arc extensions structures; connection points of the arc extension structures and the hollow cylinders are located at the outside of the hollow cylinders, and each extension structure is outward bent in an arc way; and the filling layer is the sliding material. A completely-sealed shielding layer structure is replaced with the intermittent shielding layer structure, and the shielding layers are mutually pulled through elastic extension structures, so that the cable can bend at will when required and can return to an original shape when bending is not required, the cable core canbend by a certain radian, and the edge cracking caused by repeatedly bending the cable edge for a long time is avoided.

Description

technical field [0001] The invention relates to the technical field of wired signal transmission coaxial cables, in particular to a bending-resistant and heat-dissipating copper-based alloy radio frequency coaxial cable. Background technique [0002] Coaxial cable refers to two concentric conductors, and the conductor and shield share the same axis. The most common coaxial cable consists of copper wire conductors separated by insulating materials. Outside the inner layer of insulating material is another layer of ring The conductor is the other insulation, and then the entire cable is surrounded by a sheath of PVC or Teflon material. The coaxial cable conducts alternating current instead of direct current, which means the direction of the current reverses several times per second. If you use ordinary wires to transmit high-frequency currents, this wire will act as an antenna that transmits radio to the outside. This effect consumes the power of the signal and reduces the st...

Problems solved by technology

There is also a problem with coaxial cables, that is, if a certain section of the cable undergoes relatively large extrusion or twisting deformation, the distance between the central wire and the mesh conductive layer will not be consistent, which will cause the internal radio waves to be blocked. Reflected back to the source where the signal was sent

This effect reduces the received signal power
