Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication cable, in particular to 5G high frequency signal anti-interference flexible cable. BACKGROUND

[0002] The cable is a common electrical connection, which is used to electrically connect electrical appliances together. When the cable is used, it is often necessary to connect two cables together to use. In this case, the insulating outer wall and insulating layer of the two cables are usually stripped, and then a splicing terminal is used to connect the cores of the two cables together, so as to realize the connection between the two cables.

[0003] However, since the cores of the two cables need to be connected together, the insulating outer wall and insulating layer of the cable need to be stripped. After the cores are connected, most cases are simply wrapped with insulating material. If the wrapping is not tight, the anti-interference performance of the connection between the two cables cannot be guaranteed. Especially when the cable is applied to high voltage and strong current working conditions, the cable will cause serious radiation interference to other electrical appliances around.

[0004] Therefore, it is necessary to provide a 5G high frequency signal anti-interference flexible cable to solve the above problems. SUMMARY

[0005] The purpose of the present application is to provide a 5G high frequency signal anti-interference flexible cable to solve the problem of poor anti-interference performance of the connection between the two cables after the cores are connected.

[0006] To achieve the above purpose, the present application provides the following technical scheme: The 5G high frequency signal anti-interference flexible cable comprises a cable one and a cable two. The end of the cable one and the end of the cable two close to each other are provided with exposed cores. After the two exposed cores are twisted and connected, the joint is connected by tin soldering. The outer side of the cable one and the outer side of the cable two are commonly movably sleeved with a sliding sleeve. The exposed cores are located inside the sliding sleeve. The outer side of the exposed cores is wrapped with an insulating sealing sleeve. The diameter of the insulating sealing sleeve along its axis direction is greater than the diameter of the twisted exposed cores. The inner walls of the two ends of the insulating sealing sleeve are attached to the outer walls of the ends of the cable one and the cable two. The outer side of the insulating sealing sleeve is wrapped with a metal shielding net. The outer side of the metal shielding net is wrapped with insulating rubber. The outer side of the insulating rubber is wrapped with a buffer pad. The outer side of the buffer pad is wrapped with a protective sleeve. The inner diameter of the protective sleeve is greater than the outer diameter of the cable one and the cable two.

[0007] Preferably, a self-adhesive rubber insulating belt is arranged between the exposed core and the insulating sealing sleeve, and the self-adhesive rubber insulating belt is wrapped around the exposed core.

[0008] Preferably, the sheath is internally provided with a sealed hollow chamber between the buffer pad and the sheath.

[0009] Preferably, the outer side of the sheath is provided with a liquid injection port in communication with the hollow chamber.

[0010] Preferably, the inner wall of the sliding sleeve is fixedly installed with a double-walled heat shrink tube, the inner and outer walls of the double-walled heat shrink tube are attached with hot melt glue, the inner wall of the double-walled heat shrink tube is attached to the outer wall of the sheath, the sheath is located inside the double-walled heat shrink tube, and the inner walls of the two ends of the double-walled heat shrink tube are attached to the outer surfaces of the cable one and the cable two.

[0011] Preferably, one end of the liquid injection port penetrates through the double-walled heat shrink tube.

[0012] Preferably, the sliding sleeve is in a cylindrical structure, and the two ends of the sliding sleeve are fixedly installed with elastic clamping pieces, one end of the elastic clamping piece is clamped to the outer surfaces of the cable one and the cable two, and the clamping surface of the elastic clamping piece is an arc surface matched with the cable one and the cable two.

[0013] Preferably, the sheath is in a columnar structure with a rectangular cross section, and the two ends of the sheath are installed with sealing rings.

[0014] Preferably, the metal shielding net is woven by high-conductivity copper, and the two ends of the metal shielding net are connected to the original metal shielding layers of the cable one and the cable two by welding.

[0015] Preferably, the insulating sealing sleeve is made of silicone rubber, and the inner wall of the insulating sealing sleeve is provided with a helical sealing groove, and the rotation direction of the helical sealing groove is consistent with the twisting direction of the cable one and the cable two.

[0016] The technical effects and advantages of the present application are as follows: 1. In the present application, the metal shielding net is woven by high-conductivity copper and welded to the original shielding layer of the cable to form a continuous shielding channel, which can effectively block external electromagnetic interference; the helical sealing groove of the insulating sealing sleeve is consistent with the twisting direction of the cable, and cooperates with the insulating rubber, the buffer pad and the sheath on the outer side of the metal shielding net to not only enhance the sealing performance and prevent the influence of external medium, but also attenuate high-frequency signal interference through the synergistic effect of the layers, ensuring stable 5G high-frequency signal transmission, and the design of the sliding sleeve and the elastic clamping piece enables the cable to maintain the integrity of the shielding structure when bending, further improving the anti-interference reliability.

[0017] 2. The sheath has a sealed hollow chamber inside, with an injection port on the outside for injecting epoxy resin and curing agent. After curing, it forms a hard insulating shell. Double-wall heat shrink tubing is fixedly installed on the inner wall of the sliding sleeve. Hot melt adhesive is attached to the inner and outer walls. After the epoxy resin injected into the hollow chamber cures, it enhances the insulation and waterproofness of the sheath. The hot melt adhesive in the double-wall heat shrink tubing melts when heated, further improving the sealing performance. This gives the cable high insulation and waterproofness, making it suitable for high-voltage cables or outdoor high-voltage communication scenarios. It can effectively prevent safety hazards such as leakage and short circuits.

[0018] 3. The sliding sleeve is made of polyetheretherketone material. The inner wall is mirror-finished and can slide freely along the cable axis. The cable is held by elastic clips at both ends, so that when the cable is bent, the sliding sleeve can compensate with the displacement of the cable, maintain the integrity of the shielding structure, and avoid the shielding layer from breaking or deforming due to cable bending, which would affect the anti-interference performance. It is suitable for scenarios that require frequent bending or are installed in confined spaces and complex structures. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention provides, for example Figures 1-6 The 5G high-frequency signal anti-interference flexible cable shown includes cable 1 and cable 2. Both cable 1 and cable 2 have exposed battery cores 3 at their close ends. After the two exposed battery cores 3 are twisted together, the joints are connected by soldering. The exposed battery cores 3 of cable 1 and cable 2 are electrically connected by soldering. The solder joints must be smooth and burr-free to reduce contact resistance.

[0029] Cable 1 and Cable 2 are movably fitted with a sliding sleeve 4 on their outer sides. The exposed battery core 3 is located inside the sliding sleeve 4. The sliding sleeve 4 is made of polyetheretherketone material. Its inner wall is mirror-finished and can slide freely along the cable axis to accommodate displacement compensation when the cable bends.

[0030] The exposed battery cell 3 is wrapped with an insulating sealing sleeve 6. The diameter of the insulating sealing sleeve 6 along its axis is larger than the diameter of the stranded exposed battery cell 3, and the inner walls of both ends of the insulating sealing sleeve 6 are attached to the outer walls of the ends of cable 1 and cable 2. This ensures insulation protection for the exposed battery cell 3 while forming a sealed structure through the attachment of both ends to the cable body, enhancing the insulation and sealing performance of the connection and improving anti-interference. The outer side of the insulating sealing sleeve 6 is wrapped with a metal shielding mesh 7, which is woven from high-purity copper wire with a diameter of 0.1mm. Both ends are laser-welded to the original shielding layer of the cable to achieve 360° electrical connection.

[0031] The outer side of the metal shielding mesh 7 is wrapped with insulating rubber 8, the outer side of the insulating rubber 8 is wrapped with a buffer pad 9, and the outer side of the buffer pad 9 is wrapped with a sheath 5. The inner diameter of the sheath 5 is larger than the outer diameter of cable 1 and cable 2. The insulating rubber 8 is made of neoprene rubber with a thickness of 1-1.5mm and has ozone aging resistance. The buffer pad 9 is made of polyurethane foam with a density of 40kg / m³ and an internal honeycomb pore diameter of 0.5-1mm, which can absorb bending stress. The sheath 5 is a cylindrical silicone rubber structure with fluororubber lip seals embedded at both ends and fixed to the sliding sleeve 4 by stainless steel hose clamps to ensure that the overall protection level reaches IP67.

[0032] A self-adhesive rubber insulating tape 11 is provided between the exposed battery cell 3 and the insulating sealing sleeve 6. The self-adhesive rubber insulating tape 11 is wrapped around the exposed battery cell 3 and fully adheres to the surface of the battery cell by utilizing its self-adhesive properties to form the first layer of insulation protection, effectively isolating the battery cell from the external environment. At the same time, it provides a base for the subsequent wrapping of the insulating sealing sleeve 6, enhancing the reliability of the overall insulation structure.

[0033] The sheath 5 has a sealed hollow chamber 12 located between the buffer pad 9 and the sheath 5. An injection port 13 is located on the outside of the sheath 5, connected to the hollow chamber 12. One end of the injection port 13 is threaded through a double-walled heat-shrink tubing 14. By creating the hollow chamber 12, epoxy resin and a curing agent are injected into it through the injection port 13. After curing, a rigid insulating shell is formed, suitable for high-voltage cables or outdoor applications. It possesses high insulation and waterproof properties, enhancing the protective capability of the sheath 5.

[0034] A double-wall heat shrink tubing 14 is fixedly installed on the inner wall of the sliding sleeve 4. Hot melt adhesive is applied to both the inner and outer walls of the double-wall heat shrink tubing 14. The inner wall of the double-wall heat shrink tubing 14 adheres to the outer wall of the sheath 5, and the sheath 5 is located inside the double-wall heat shrink tubing 14. The inner walls at both ends of the double-wall heat shrink tubing 14 adhere to the outer surfaces of cable 1 and cable 2. During installation, a heat gun is used to heat the hot melt adhesive on the double-wall heat shrink tubing 14, further enhancing the adhesion between the double-wall heat shrink tubing 14 and the sliding sleeve 4, while also improving the sealing performance of the sheath 5.

[0035] The sliding sleeve 4 has a cylindrical structure. Both ends of the sliding sleeve 4 are fixedly installed with elastic clips 10. One end of the elastic clip 10 is clamped on the outside of cable 1 and cable 2, and the clamping surface of the elastic clip 10 is set as an arc surface that is compatible with cable 1 and cable 2.

[0036] The sheath 5 has a rectangular cross-section and is a columnar structure. Both ends of the sheath 5 are equipped with sealing rings, which are not shown in the attached drawings.

[0037] The metal shielding mesh 7 is made of copper with high conductivity. Both ends of the metal shielding mesh 7 are connected to the original metal shielding layers of cable 1 and cable 2 by welding.

[0038] The insulating sealing sleeve 6 is made of silicone rubber. The inner wall of the insulating sealing sleeve 6 is provided with a spiral sealing groove, and the spiral direction of the sealing groove is consistent with the twisting direction of cable 1 and cable 2. The insulating sealing sleeve 6 is made of silicone rubber, and the depth of the spiral sealing groove on the inner wall is 0.5-1mm, the pitch is 2-3mm, and the spiral direction is consistent with the twisting direction of the cable, which can form a labyrinth-type sealing structure, further improving the protection.

[0039] In this embodiment of the invention, after stripping the insulation material from the ends of the two cables, the two exposed battery cores 3 are soldered together using methods such as soldering. First, self-adhesive rubber insulating tape 11 is wrapped around the exposed battery cores 3. Then, an insulating sealing sleeve 6 is used to wrap the wrapped exposed battery cores 3. Because the insulating sealing sleeve 6 is made of elastic and malleable silicone rubber, its inner walls at both ends are tightly attached to the outer sides of the ends of cable 1 and cable 2, while the remaining portion adheres to the surface of the exposed battery cores 3, improving insulation. A metal shielding mesh 7 woven from high-purity copper wire is used to wrap the outside of the insulating sealing sleeve 6. Insulating rubber 8 is used to wrap the metal shielding mesh 7. The insulating rubber 8 has good flexibility and elasticity, and can tightly fill the metal shielding mesh 7 and subsequent... The tiny gaps between the materials further prevent the leakage and intrusion of electromagnetic interference signals. At the same time, the insulating rubber 8 also has a certain degree of waterproof performance, which can protect the cable connection from water erosion and improve the reliability and stability of the connection. The buffer pad 9 reduces the impact of external forces on the inside of the cable. Then, epoxy resin and curing agent are injected into the hollow cavity 12 through the injection port 13. After curing, a hard insulating shell is formed, which improves the protective ability of the sheath 5. The material of the sliding sleeve 4 and the mirror treatment of the inner wall allow the sliding sleeve 4 to slide freely on the surface of cable 1 and cable 2. After adjusting the position of the sliding sleeve 4, the hot melt adhesive of the double-wall heat shrink tubing 14 is used to strengthen the adhesion between the double-wall heat shrink tubing 14 and the sliding sleeve 4. Finally, the elastic clip 10 is used to fix the sliding sleeve 4 to the surface of cable 1 and cable 2 to prevent loosening or falling off.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
