Description

Technical Field

[0001] The utility model specifically relates to a reinforced protection device for communication cables, belonging to the technical field of communication cables. Background Art

[0002] Communication cables are cable products with wires or optical fibers as core components, used to transmit electrical signals or optical signals. They are widely used in telephone, network, radio and television, industrial control and other fields. According to their structure, they can be divided into four categories: covered wires, overhead wires, communication cables and communication optical cables. Covered wires use a twisted core of copper wire and steel wire, covered with a wear-resistant insulation layer, and are suitable for short-distance field communications; overhead wires are composed of bare metal wires, with large transmission capacity but weak anti-interference ability. Communication cables include symmetrical cables and coaxial cables. The former transmits signals through a twisted wire group, and the latter uses a coaxial design to achieve multi-channel carrier communication. Communication optical cables use optical fiber as a medium, with the advantages of large capacity, small size and anti-interference. According to their functions, they are divided into audio cables, digital cables and carrier frequency cables, corresponding to the needs of urban communications, digital transmission and long-distance communications respectively. In special scenarios, field cables are light and tensile-resistant, submarine cables are divided into shallow sea / deep sea and have protective structures, and underwater cables have thickened sheaths to enhance airtightness.

[0003] After searching, the Chinese patent publication number CN219351187U discloses a reinforced protective device for communication cables. Although this patent can not only assist in fixing the communication cables of the protective kit, but also assist in opening the side jacket to clamp the laid communication cables, thereby avoiding the problem of damage to the protective device due to friction between the laid communication cables and the docked communication cables, the patent has poor compatibility with multiple cables. The adjustment component manually adjusts the opening and closing angle through the rack, but the wire diameter range of the adapted communication cables is not quantified. In actual construction, the side jackets need to be frequently replaced for communication cables of different specifications. Utility Model Content
