Description

Technical Field

[0001] This application belongs to the field of communication cable technology, and in particular relates to a self-melting ice radio frequency coaxial cable and its kit. Background Technology

[0002] Outdoor RF coaxial cables are often laid in open configurations such as overhead, wall-mounted, and open-air cable trays, lacking enclosed protection and load-bearing buffer structures. In extreme weather conditions like blizzards, snowflakes continuously accumulate, and after rain and snow melt, they absorb moisture and clump together, then freeze at low temperatures to form a high-density snow and ice layer. Combined with the natural sag of long-distance cables, snow easily accumulates at the cable's curved base, creating a long-term, localized static concentrated load. Low winter temperatures reduce the toughness and compression resistance of the cable's outer sheath and insulation materials, significantly weakening the cable's overall deformation resistance. Under prolonged pressure from accumulated snow, the cable continuously endures external force, gradually causing irreversible mechanical deformation, creating potential hazards for future operational failures. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a self-melting RF coaxial cable and its kit to overcome the above-mentioned difficulties faced by the outdoor deployment of RF coaxial cables in the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is:

[0005] A self-melting ice radio frequency coaxial cable, comprising:

[0006] Inner layer of cable;

[0007] A sheath, covering the outside of the inner layer of the cable; the sheath is divided into a first part and a second part by a vertical diameter;

[0008] A heat-absorbing film, wherein the heat-absorbing film is partially adhered to the upper side of the first part and partially extends downward toward the first part;

[0009] A lubricating coating is applied to the upper side of the second part.

[0010] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the heat-absorbing film includes an adhesive coating area and an extension area, the adhesive coating area is bonded to the upper side of the first portion by an adhesive, and the extension area extends downward toward the first portion.

[0011] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the heat-absorbing film is made of EPDM material or neoprene rubber material.

[0012] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the surface of the heat-absorbing film is coated with a black coating.

[0013] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the thickness of the heat-absorbing film is 0.5mm to 1.5mm.

[0014] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the lubricating coating is an aqueous acrylic-PEG composite coating, an epoxy-MoS2 / PEG coating, a modified organosilicon-polyether composite hydrophilic coating, or a fluorine-modified polyurethane hydrophilic lubricating coating.

[0015] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the sheath is made of HDPE material.

[0016] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the cross-sectional shape of the sheath is a circle with a notch.

[0017] Preferably, in the self-melting ice radio frequency coaxial cable of the present invention, the notch is arc-shaped.

[0018] A self-melting ice radio frequency coaxial cable kit includes:

[0019] The self-melting ice radio frequency coaxial cable described above;

[0020] The fastener is capable of being fitted onto the sheath, and the inner wall contour of the fastener matches the outer wall contour of the sheath.

[0021] The beneficial effects of this invention are as follows: In the self-melting ice radio frequency coaxial cable of this invention, the heat-absorbing film is partially adhered to the upper side of the first part and partially extends downwards from the first part; a lubricating coating is applied to the upper side of the second part. With this structure, when snow clumps at the top of the cable, the lower half of the heat-absorbing film rapidly heats up under sunlight, transferring heat to the upper half of the film. This causes the lower side of the snow on the upper side of the first part to gradually melt, resulting in the clumped snow layer shifting its center of gravity towards the second part. Furthermore, because the lubricating coating has extremely low adhesion in a wet state, the clumped snow layer can naturally fall off under this shifted center of gravity, achieving the effect of self-melting ice on the cable.

[0042] Example 1

[0043] This embodiment provides a self-melting ice radio frequency coaxial cable, such as... Figure 1 , Figure 2 As shown, it includes: cable inner layer 1, sheath 2, heat-absorbing film 3, and lubricating coating 4.

[0044] The sheath 2 covers the outside of the inner layer 1 of the cable; the sheath 2 is divided into a first part 21 and a second part 22 by a diameter along the vertical direction of the sheath 2.

[0045] The heat-absorbing film 3 is partially adhered to the upper side of the first part 21 and partially extends downwards from the first part 21; the lubricating coating 4 is coated on the upper side of the second part 22. The function of the heat-absorbing film 3 is to absorb heat and raise its temperature under sunlight, so as to transfer heat to the hardened snow layer 6 covering it, thereby accelerating the melting of the snow. The function of the lubricating coating 4 is to provide a contact surface with low friction with the snow layer 6, making it difficult for the snow layer 6 to adhere to its surface.

[0046] The self-melting ice radio frequency coaxial cable of this embodiment, through its structure, allows snow to accumulate at the top of the cable, such as... Figure 4 As shown, due to the rapid temperature rise of the lower half of the heat-absorbing film 3 under sunlight, heat is transferred to the upper half of the heat-absorbing film 3, causing the lower side of the snow on the upper side of the first part 21 to gradually melt. This causes the hardened snow layer 6 to shift its center of gravity towards the second part 22. Furthermore, because the lubricating coating 4 has extremely low adhesion in a wet state, such as... Figure 5 As shown, the hardened snow layer 6 can naturally fall off under the state of center of gravity deviation, achieving the effect of self-melting ice on the cable.

[0047] In an alternative embodiment, such as Figure 2 , Figure 3As shown, the heat-absorbing film 3 includes an adhesive coating area 31 and an extension area 32. The adhesive coating area 31 is bonded to the upper side of the first part 21 by an adhesive, and the extension area 32 extends downwards from the first part 21. The function of the adhesive coating area 31 is to provide sufficient contact area for the adhesive to ensure that it can adhere to the surface of the sheath 2 without falling off; the function of the extension area 32 is to expand the total area of ​​the heat-absorbing film 3 so that the heat-absorbing film 3 is not completely covered by snow, thereby improving the heat absorption efficiency of the heat-absorbing film 3 under sunlight.

[0048] Optionally, the lower edge of the extension area 32 is flush with the lowest point of the sheath 2. This setting can avoid conflicts between layers caused by the extension area 32 being too long when the cable is reeled.

[0049] In an optional embodiment, the heat-absorbing film 3 is made of EPDM (Ethylene Propylene Diene Monomer) or neoprene rubber.

[0050] EPDM material has excellent outdoor anti-aging properties, is resistant to ozone and ultraviolet rays, and its performance degrades little after long-term outdoor use; it has good heat absorption and heat transfer properties, good thermal stability, and stable heat transfer effect under thermal cycling; it has good processability, is easy to cut and shape, and has good adhesion and covering properties.

[0051] Neoprene rubber has excellent outdoor anti-aging properties and is resistant to acid and alkali corrosion, making it suitable for complex and harsh outdoor working conditions; it has good heat absorption and heat transfer properties, which can effectively store and transfer solar heat; and it has moderate processability, which can be cut and bent to meet the requirements of cable wrapping and assembly.

[0052] Both materials meet the requirements of this solution for outdoor cables with self-heating snow melting in terms of outdoor anti-aging performance, heat absorption and heat transfer performance, and processability.

[0053] Optionally, carbon black or black additives can be added to the EPDM or neoprene rubber substrate to color it, making its surface black and improving its heat absorption capacity under light.

[0054] In an optional embodiment, the surface of the heat-absorbing film 3 is coated with a black paint to enhance its heat absorption capacity under light.

[0055] In an optional embodiment, the thickness of the heat-absorbing film 3 is 0.5 mm to 1.5 mm to ensure low material consumption and sufficient structural strength.

[0056] In an optional embodiment, the lubricating coating 4 is an aqueous acrylic-PEG (Polyethylene Glycol) composite coating, an epoxy-MoS2 / PEG coating, a modified silicone-polyether composite hydrophilic coating, or a fluorine-modified polyurethane hydrophilic lubricating coating. These coatings possess excellent self-lubricating properties. When a small amount of meltwater appears at the interface between the hardened snow and the coating, forming a thin water film, the coating can quickly form a stable hydrophilic lubricating layer with the meltwater, significantly reducing the coefficient of friction at the contact surface. Through the low-friction interface effect, the hardened snow easily slides off the surface, making it difficult for it to adhere and accumulate, thereby inhibiting snow hardening and adhesion.

[0057] Properties of water-based acrylic-PEG hydrophilic coating: Dry friction coefficient: 0.4~0.5; decreases to 0.08~0.12 within 10 seconds of contact with water;

[0058] Performance of epoxy-MoS2 / PEG composite coating: Dry friction: 0.35~0.4; Wet friction: 0.06~0.09; Outdoor life: 8~10 years, resistant to salt spray and hydrolysis;

[0059] Properties of modified organosilicon-polyether composite hydrophilic coating: wet friction coefficient 0.07~0.10;

[0060] Fluorine-modified polyurethane hydrophilic lubricating coating properties: UV resistant, acid rain resistant, humid heat resistant, outdoor life of more than 15 years, can be used in harsh environments such as coastal areas and strong sunlight; coefficient of friction: 0.05~0.08 when in contact with water.

[0061] In an optional embodiment, the sheath 2 is made of HDPE (High Density Polyethylene) material, which has good outdoor anti-aging properties.

[0062] Example 2

[0063] This embodiment provides a structure for a sheath 2, such as... Figure 6 , Figure 7 As shown, the cross-sectional shape of the sheath 2 is a circle with a notch 23, so as to position the orientation angle of the sheath 2 and ensure that the first part 21 and the second part 22 of the sheath 2 are located on the left and right sides respectively.

[0064] In an alternative embodiment, such as Figure 6 As shown, the notch 23 is arc-shaped, and the manufacturing process is relatively simple. It only requires cutting off a small part of the sheath 2 made by the existing mold along a straight line.

[0065] like Figure 7 As shown, this embodiment provides a self-melting ice radio frequency coaxial cable kit, including:

[0066] This embodiment features a self-melting ice radio frequency coaxial cable and a matching fastener 5. The fastener 5 can be fitted onto the sheath 2, and the inner contour of the fastener 5 matches the outer contour of the sheath 2. By using this fastener 5 to install the self-melting ice radio frequency coaxial cable of this embodiment, it is possible to ensure that the cable is installed at a stable angle without tilting, and to ensure that the first part 21 and the second part 22 of the sheath 2 are located on the left and right sides respectively, which is beneficial to maintaining the self-melting ice effect.

[0067] Installation instructions: The heat-absorbing film 3 at the installation position of the fastener 5 can be partially cut off with scissors to avoid conflict with the fastener 5.

[0068] Based on the above-described preferred embodiments according to this application, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this application. The technical scope of this application is not limited to the contents of the specification, but must be determined according to the scope of the claims.
