Description

Technical Field

[0001] The utility model belongs to the technical field of cables, and in particular relates to a reinforced protection cable. Background Art

[0002] Wires and cables refer to materials used for power, electrical and related transmission purposes, usually consisting of several or several groups of wires. There is no strict boundary between "wires" and "cables"; usually products with a small number of cores, small product diameters, and simple structures are called wires, those without insulation are called bare wires, and the rest are called cables;

[0003] Chinese patent number CN219303382U discloses a flexible cable, which includes a plurality of cores, a wrapping layer, an inner sheath, an outer sheath, a heat-conducting member and a high-temperature flame-retardant filling layer. The heat generated by the cable is transferred to the surrounding of the channel by the arranged heat-conducting member, and the heat exchange medium flows through the channel to take away the heat, thereby avoiding excessive temperature to accelerate the aging of the insulation layer and prevent the insulation layer from being broken down, thereby improving the service life of the cable;

[0004] Cables are usually laid in various locations in the city. During the laying process, the cables usually bend and deform to a certain extent. When the length between two points is constant, if the cable bends and deforms, the required cable length will become longer than when the cable is straight, thereby increasing the laying process. For this reason, we propose a cable with enhanced protection. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1: Please refer to Figures 1 to 3The utility model provides a technical solution: a reinforced protection cable, including a skeleton 10, the outside of the skeleton 10 is clamped with wire cores 8 and optical fibers 9 distributed at equal distances, and the wire cores 8 and optical fibers 9 are alternately distributed, the outside of the wire cores 8 and optical fibers 9 is coated with a cable tape 5, and the cable tape 5 and the wire cores 8 and optical fibers 9 are filled with a filling rope 6 for filling the internal pores to fix and protect the wire cores 8 and optical fibers 9, the outside of the filling rope 6 is coated with a cable tape 5, and the outside of the cable tape 5 is coated with an inner sheath 4, the outside of the inner sheath 4 is coated with a steel belt armor 3 to prevent external cutting damage, and the outside of the steel belt armor 3 is coated with an outer sheath 1, a core hole 16 is opened inside the skeleton 10, and a high-elastic conductor 11 is inserted into the inside of the core hole 16.

[0021] From the above description, it can be seen that the utility model has the following beneficial effects: through the provision of the skeleton 10 and the highly elastic conductor 11, during the actual laying process, the highly elastic conductor 11 can greatly enhance the elastic effect of the cable, so that the cable will not produce too many small bends and deformations, thereby avoiding the waste of cable length and effectively saving the cost required for laying.

[0022] For further information, see Figure 2 Preferably, the outside of the high-elastic conductor 11 is covered with an elastic sleeve 12, and the elastic sleeve 12 is located inside the core hole 16, the outside of the wire core 8 is covered with a wire core sheath 7, and the wire core sheath 7 is in contact with the skeleton 10.

[0023] Example 2: Please refer to Figures 1 to 3 As shown, based on the first embodiment, the utility model provides a technical solution: the outside of the optical fiber 9 is coated with an optical fiber sheath 13, and the outside of the optical fiber sheath 13 is coated with an insulating layer 14 for isolating the heat generated by the core 8, and the side outer wall of the skeleton 10 is provided with equidistantly distributed card grooves 15, and the core 8 is clamped in the inside of the card groove 15, and the inside of the skeleton 10 is provided with equidistantly distributed cavities 17.
