Description

Technical Field

[0001] The utility model relates to the field of radio frequency cables, in particular to a bending-resistant and phase-stable radio frequency cable. Background Art

[0002] With the rapid development of my country's communications industry, the requirements for RF cables in communications are becoming increasingly higher. During the use of RF cables, multi-conductor cables often have entanglement between conductors, resulting in severe wear and tear, which reduces the service life and stability. The usual solution is to cover each conductor with a protective layer, but the entanglement and wear phenomenon still exists and needs to be improved.

[0003] For example, a patent for a phase-stable radio frequency cable (announcement number: CN209087434U) includes a conductor, an inner shielding layer, an outer shielding layer and an outer sheath, wherein the outer shielding layer includes a reflective layer and an absorption layer from the inside to the outside, and also includes an elastic center guide post, a plurality of grooves are evenly distributed around the center guide post, there are multiple conductors, which are respectively built into the center guide post groove, and each conductor is coated with an insulating layer on the outside, the center guide post is coated with a heat shrinkable film layer, and the inner shielding layer is a composite shielding layer formed by aluminum foil and copper mesh. This radio frequency cable places the conductor into the center guide post groove, uses the center guide post as the carrier of the conductor, and the heat shrinkable film layer is heated to tightly compress and shrink the center guide post, thereby stabilizing the position of the conductor and avoiding the entanglement of multiple conductors, which leads to severe wear. At the same time, this structure improves production efficiency. In addition, the inner and outer shielding layers greatly enhance the shielding performance of the cable and improve the performance of signal transmission.

[0004] The above patent improves production efficiency and signal transmission performance through heat shrink film layer and shielding layer. In daily use, the cable may need to be bent and folded during the transmission connection process, causing the conductor in the cable to break easily at the bend after repeated use, that is, the bending performance of the cable cannot meet the use requirements, reducing the bending resistance of the device. Therefore, it is necessary to invent a bend-resistant and phase-stable RF cable to solve the above problem. Utility Model Content
