Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to an inorganic insulated flexible fireproof cable. Background Technology

[0002] Fire-resistant cables, as guardians of safety in the cable industry, perform exceptionally well in practical applications. They operate reliably in densely populated areas such as high-rise buildings, hospitals, and schools, as well as in industrial environments like petrochemical and power plants. Their waterproof, explosion-proof, and corrosion-resistant properties make them fearless in harsh conditions. Compared to ordinary cables, fire-resistant cables have a longer service life and lower maintenance costs.

[0003] The existing fire-resistant cables need to be improved in terms of tensile strength, compressive strength, and high-temperature resistance. Utility Model Content

[0004] The purpose of this invention is to provide an inorganic insulated flexible fireproof cable that has stronger tensile, compressive, and high-temperature resistance properties, and is more practical.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An inorganic insulated flexible fireproof cable includes a fireproof cable, the fireproof cable comprising a second rubber sheath, a rubber seat penetrating the interior of the second rubber sheath, a plurality of spiral-shaped snap-fit ​​grooves provided on the side surface of the rubber seat, and cable cores snapped into the interior of the snap-fit ​​grooves, the cable cores being provided in multiple manner, and a through hole provided at the middle position of the rubber seat.

[0007] By adopting the above technical solution, the cable core can be limited, and the overall tensile and compressive strength can be improved.

[0008] Furthermore, the cable core includes a copper wire core, and the copper wire core is wrapped with a first rubber sheath.

[0009] By adopting the above technical solutions, the insulation performance of the entire cable can be further improved.

[0010] Furthermore, the rubber seat and cable core are externally wrapped with mica tape.

[0011] By adopting the above technical solutions, the internal high-temperature resistance of the entire cable can be improved.

[0012] Furthermore, the mica tape is wrapped with an aluminum foil layer.

[0013] By adopting the above technical solutions, the overall anti-interference performance of the cable can be improved.

[0014] Furthermore, the second rubber sheath is wrapped around the outside of the aluminum foil wrapping layer, and a wire mesh layer is laid inside the second rubber sheath.

[0015] By adopting the above technical solution, the structural strength of the second rubber sheath can be effectively improved.

[0016] Furthermore, multiple anti-collision protrusions are provided on the outer surface of the second rubber sleeve.

[0017] By adopting the above technical solutions, the surface impact resistance can be effectively improved.

[0018] In summary, the beneficial technical effects of this utility model are as follows:

[0019] 1. This utility model incorporates a rubber seat inside the fireproof cable, with multiple spirally distributed snap-fit ​​grooves on the side surface of the rubber seat. The cable cores are snapped into the grooves, thus limiting the position of multiple cable cores. This prevents mutual wear between the cable cores during cable laying and subsequent use, and avoids surface damage to the cable cores. It also increases the length of the cable cores per unit length of the fireproof cable, preventing breakage under thermal expansion and contraction. Furthermore, the through hole in the middle of the rubber seat provides positional compensation for cable deformation when the cable is subjected to external pressure, preventing damage from compression. Both functionality and practicality are effectively improved.

[0020] 2. This utility model effectively improves the high temperature resistance and anti-interference performance of the entire cable by wrapping mica tape around the rubber seat and then wrapping aluminum foil around the mica tape. Both the functionality and practicality are further improved. Attached Figure Description

[0023] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0024] Reference Figure 1An inorganic insulated flexible fireproof cable includes a fireproof cable 1, which contains a second rubber sheath 9. A rubber seat 2 penetrates the interior of the second rubber sheath 9. Multiple spiral-shaped snap-fit ​​grooves are provided on the side surface of the rubber seat 2, and cable cores 4 are snapped into the interior of these grooves. Multiple cable cores 4 are provided. A through hole 3 is provided in the middle of the rubber seat 2. Each cable core 4 contains a copper wire core 5, and the copper wire core 5 is wrapped with a first rubber sheath 6. The fireproof cable utilizes a rubber seat 2 inside and multiple spirally distributed snap-fit ​​grooves on its side surface to snap into the cable cores. The internal clamping groove of the cable core 4 allows the rubber seat 2 to limit the position of multiple cable cores 4, preventing mutual wear between the cable cores 4 during cable laying and subsequent use, and avoiding damage to the surface of the cable cores 4. It also increases the length of the cable cores 4 per unit length of fireproof cable, preventing breakage of the cable cores 4 under thermal expansion and contraction. In addition, the through hole 3 in the middle of the rubber seat 2 can provide position compensation for cable deformation when the cable is subjected to external compression, preventing the cable from being squeezed and broken. The functionality and practicality are both effectively improved.

[0025] Reference Figure 1 The rubber seat 2 and the cable core 4 are wrapped with mica tape 7, and the mica tape 7 is wrapped with an aluminum foil wrapping layer 8. By wrapping the rubber seat 2 with mica tape 7 and the mica tape 7 with aluminum foil wrapping layer 8, the high temperature resistance and anti-interference performance of the entire cable can be effectively improved, and the functionality and practicality are further improved.

[0026] Reference Figure 1 The second rubber sheath 9 is wrapped around the outside of the aluminum foil sheath 8. A steel wire mesh layer 10 is laid inside the second rubber sheath 9. Multiple anti-collision protrusions 11 are provided on the outer surface of the second rubber sheath 9. The steel wire mesh layer 10 can be used to improve the internal structural strength of the second rubber sheath 9, while the anti-collision protrusions 11 can be used to improve the anti-collision performance of the cable surface.

[0027] Working principle: During use, the cable is first laid in the designated location. During the laying process, a rubber seat 2 is installed inside the fireproof cable, and multiple spirally distributed snap-fit ​​grooves are set on the side surface of the rubber seat 2. The cable core 4 is snapped in the snap-fit ​​grooves. Therefore, the position of multiple cable cores 4 can be limited by the rubber seat 2, which can prevent the cable cores 4 from wearing each other during the laying and subsequent use, and prevent the surface of the cable cores 4 from being damaged. At the same time, it can increase the length of the cable cores 4 per unit length of fireproof cable, and prevent the cable cores 4 from breaking under thermal expansion and contraction. The through hole 3 in the middle of the rubber seat 2 can provide position compensation for the deformation of the cable when the cable is subjected to external compression, and prevent the cable from being crushed and damaged. At the same time, the anti-collision protrusions 11 set on the outer surface of the second rubber sheath 9 can effectively improve the anti-collision performance of the cable surface. In subsequent use, by wrapping the rubber seat 2 with mica tape 7 and then wrapping the mica tape 7 with aluminum foil sheath 8, the high temperature resistance and anti-interference performance of the entire cable can be effectively improved.

[0028] The specific real-time examples described herein are preferred real-time examples of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
