Description

Technical Field

[0001] The utility model relates to the technical field of communication cables, in particular to a wear-resistant communication cable with an anti-interference function. Background Art

[0002] Communication cables are cables used to transmit data, voice, and video signals. They typically consist of multiple conductors and insulation layers to ensure stable and secure signal transmission. Widely used in fields such as telephones, internet, and television, communication cables efficiently connect various communication devices. They play a vital role in modern information transmission and support a wide range of communication activities in daily life.

[0003] Publication number CN221352407U discloses a communications cable comprising a cable body comprising a cable core and an outer protective layer covering the cable core. The cable core comprises multiple groups of cable core units, each of which comprises two insulated wire cores. The insulated wire cores comprise a conductor, the outer periphery of which is covered with a foamed insulation layer, which is then covered with a solid insulation layer. This method reduces the dielectric constant of the conductor insulation layer, thereby improving the transmission performance of the conductor insulation layer.

[0004] In order to improve the anti-interference performance of communication cables, most existing communication cables usually have a shielding layer on the outer surface of the cable core to play an anti-interference role. During high-frequency communication, the anti-interference effect of using only the shielding layer is not good, and certain internal communication interference will still occur between the cores. For this reason, we propose a wear-resistant communication cable with anti-interference function. Utility Model Content

[0005] The purpose of the present invention is to provide a wear-resistant communication cable with anti-interference function, so as to solve the problem proposed in the above background technology that the anti-interference effect of using only the shielding layer is poor, resulting in certain internal communication interference between the cores.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A wear-resistant communication cable with anti-interference function includes multiple groups of cable cores, the outer sides of the multiple groups of cable cores are provided with inner sheaths, a partition frame is installed in the inner sheath, the multiple groups of cable cores are distributed in a circular array in the partition frame, and the outer wall of the partition frame is coated with an anti-interference coating, the outer surface of each group of cable cores is provided with an inner shielding layer, the outer side of the inner sheath is provided with an anti-interference layer, a pressure-resistant layer, a flame-retardant layer and an outer sheath in sequence, and the outer surface of the outer sheath is provided with a wear-resistant layer.

[0008] Furthermore: a plurality of groups of elastic columns are connected in the compression-resistant layer, and rubber filling bodies are filled between adjacent elastic columns.

[0009] Furthermore: a filling layer is provided between the partition frame and the cable inner core.

[0010] Furthermore: the anti-interference coating is a copper-based conductive coating.

[0011] Further: The inner shielding layer and the anti-interference layer are both made of tinned copper braid.

[0012] Furthermore: the flame retardant layer is a low-smoke halogen-free flame retardant material layer.

[0013] Furthermore: the outer surface of the wear-resistant layer is coated with a wear-resistant coating.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model separates multiple groups of cable cores through a separator frame. The inner shielding layer on the outer surface of the cable core cooperates with the anti-interference coating on the outer wall of the separator frame to play an anti-interference role from the inner side, avoiding mutual interference between adjacent cable cores. The anti-interference layer plays an anti-interference role from the outer side. The double anti-interference effect improves the anti-interference performance of the communication cable; the wear-resistant layer improves the wear resistance of the communication cable, the flame retardant layer provides the fire resistance of the communication cable, and the multiple groups of elastic columns and rubber fillers in the pressure-resistant layer have a certain elasticity, which improves the strength and pressure resistance of the communication cable and ensures the service life of the communication cable.
