Description

Technical Field

[0001] The present invention relates to the technical field of cables, and specifically to a cable with reinforced insulating glue at the cable head. Background Art

[0002] A cable is usually a rope-like object formed by stranding several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a central wire. The whole is covered with a highly insulating covering layer. Therefore, a cable has the characteristics of conducting electricity inside and being insulated outside, and can transmit electricity or information from one place to another. There are many types of cables, which can be divided into power cables, communication cables, control cables, etc. according to their uses. Power cables are mainly used in power systems to transmit and distribute electrical energy. Communication cables are responsible for transmitting communication signals such as telephones and data. Control cables are widely used in various control systems to transmit control signals.

[0003] When existing cables are in use, a connector is usually placed outside the cable head for fixation. However, the sealing effect of the connector is not good. Due to the lack of tight sealing, the connector may not firmly fix the cable, which increases the risk of short circuit or leakage at the cable joint, and may thus trigger electrical faults. Electrical faults not only affect the normal operation of equipment, but also pose a serious threat to personnel safety. In addition, a connector with poor sealing performance is likely to expose the cable connection to the influence of external adverse factors such as moisture, dust, and chemicals. These environmental factors will accelerate the aging process of the cable and shorten its service life. Over time, the maintenance cost of the cable system will increase significantly because frequent repair and replacement of cable joints will consume a large amount of manpower, material resources, and financial resources.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present invention, during the assembly process of the cable and the joint, the protective sleeve realizes precise clamping through the linkage structure of gear transmission and rack propulsion. After the arc-shaped plate drives the clamping block to closely fit with the protective layer, the spring drives the piston to extrude the liquid insulating glue in the glue storage cavity, penetrate the sealing film to form a uniformly covered cured composite layer. The cured glue layer and the clamping block cooperate with each other, having multiple protective characteristics such as isolating moisture penetration, strengthening connection rigidity, and dispersing external impacts, which can effectively block the intrusion of water vapor or external pollutants and cause deterioration of the joint insulation performance. The enhanced mechanical stability also significantly suppresses the contact resistance fluctuation caused by the vibration environment.

[0018] 2. In the present invention, the outer protective layer of the cable can resist ultraviolet rays, mechanical friction, and erosion by oil, acid, and alkali. The rubber inner lining layer can balance the stress distribution of the conductor. The shielding layer uses high conductivity to bidirectionally block electromagnetic interference to ensure the purity of the signals of precision equipment. The fireproof layer releases inert gas to inhibit combustion when on fire to ensure the emergency function in the initial stage of a fire. The shock-absorbing layer absorbs high-frequency vibrations and thermal stress impacts to prevent the conductor from fatigue fracture. The filling layer maintains the roundness of the cable core and reduces the bending stress concentration. The insulating layer blocks the risk of electric leakage, and its corrosion-resistant characteristics protect the conductor. The high-purity oxygen-free copper conductor, with its low resistivity and dense lattice structure, maintains stable conductivity in a harsh environment.

[0019] 3. In the present invention, a temperature-measuring cable is integrated beside the internal conductor of the cable, and the temperature rise data is monitored in real time through the thermal sensitive measuring points, and people are reminded to take timely measures when the temperature is abnormal to avoid fire caused by heat accumulation. The second insulating layer prevents the signal acquisition system from short-circuiting and failing, and avoids environmental medium interference with the sensitivity of temperature-measuring elements such as fiber Bragg gratings and thermocouples.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: Refer to Figure 1 - Figure 8 As shown, the present invention provides a cable head insulating glue reinforced cable, including a main body mechanism 1, and a protection mechanism 2 is movably sleeved on the outer wall of the main body mechanism 1;

[0031] The protection mechanism 2 includes a protective sleeve 201. Six first movable holes 202 are formed in the outer surface wall of the protective sleeve 201. A second movable hole 203 is formed in the outer surface wall of the protective sleeve 201. A connector 204 is arranged at the top of the protective sleeve 201. A rotating shaft 205 is movably inserted into the inner surface wall of the second movable hole 203. A first bevel gear 206 is fixedly sleeved on the outer surface wall of the rotating shaft 205. An adjusting wheel 207 is fixedly sleeved on the outer surface wall of the rotating shaft 205. A second bevel gear 208 is meshed and connected to the outer surface wall of the first bevel gear 206. A first gear 209 is fixedly installed at the bottom of the second bevel gear 208. A fixing ring 210 is fixedly inserted into the inner surface wall of the protective sleeve 201. Six fixing rods 211 are fixedly installed at the bottom of the fixing ring 210. Second gears 212 are movably sleeved on the outer surface walls of the six fixing rods 211, and the outer surface walls among the six second gears 212 are meshed and connected to the outer surface wall of the first gear 209. Third gears 213 are movably sleeved on the outer surface walls of the six fixing rods 211, and the bottoms of the six second gears 212 are fixedly connected to the tops of the third gears 213. Rack bars 214 are meshed and connected to the outer surface walls of the six third gears 213, and the tops among the six rack bars 214 are in contact with the bottom of the first gear 209. The inner surface walls of the six first movable holes 202 are movably inserted into the outer surface walls of the rack bars 214. Arc-shaped plates 215 are fixedly installed at the bottoms of the six rack bars 214. Pistons 216 are fixedly installed on the outer surface walls of the six arc-shaped plates 215. A set of springs 217 are fixedly installed on the outer surface walls of the six arc-shaped plates 215. Clamping blocks 218 are fixedly installed among the outer surface walls of the six groups of springs 217. Glue storage chambers 219 are formed in the outer surface walls of the six clamping blocks 218, and the inner surface walls of the glue storage chambers 219 are movably inserted into the outer surface walls of the pistons 216. Mounting holes 220 are formed in the inner surface walls of the six clamping blocks 218. Sealing films 221 are arranged on the inner surface walls of the six mounting holes 220;

[0032] The main body mechanism 1 includes a protective layer 101. The outer surface walls among a group of clamping blocks 218 are in contact with the outer surface wall of the protective layer 101.

[0033] In this embodiment, when the user connects the cable to the connector 204, the protective sleeve 201 can be first sleeved on the outer wall of the protective layer 101, so that one side of the inner wall of the protective sleeve 201 contacts a group of conductors 108 and the temperature measuring cable 110. Subsequently, the adjusting wheel 207 can be rotated. When the adjusting wheel 207 rotates, it drives the internally inserted rotating shaft 205 to rotate inside the second moving hole 203. At this time, the first bevel gear 206 fixedly sleeved on the outer wall of the rotating shaft 205 starts to rotate, and the first bevel gear 206 will drive the second bevel gear 208 below to rotate together. Since the first gear 209 is fixedly installed below the second bevel gear 208, the first gear 209 will rotate in the same direction as the second bevel gear 208 and drive the six second gears 212 meshed with the outer wall of the first gear 209 to move. At this time, the six second gears 212 rotate around the fixed rod 211 as the center and drive the third gear 213 at the bottom to also rotate around the fixed rod 211 as the center. The six third gears 213 are all meshed and connected with the rack 214. Therefore, when the third gear 213 rotates, it can drive the rack 214 to move forward and drive the arc-shaped plate 215 at the bottom to approach the protective layer 101. When the clamping block 218 on one side of the arc-shaped plate 215 fits with the protective layer 101, the position no longer changes, but the arc-shaped plate 215 will continue to be driven by the advancing rack 214, thereby squeezing the spring 217 and pushing the piston 216 to move forward inside the glue storage chamber 219. At this time, the liquid insulating glue stored inside the glue storage chamber 219 is squeezed by the piston 216, breaks through the sealing film 221 and flows out, and contacts the protective layer 101, the protective sleeve 201 and the clamping block 218, thereby forming a dense protective film, effectively isolating moisture and dampness, preventing the cable connector 204 from suffering from a decline or damage in insulation performance due to moisture, and also increasing the mechanical strength of the cable connector 204, making it more firm and durable, and helping to reduce the risk of loosening or damage of the cable connector 204 caused by external forces.

[0034] Embodiment 2: According to Figures 1 - 3 and Figure 8As shown, the main body mechanism 1 includes a protective layer 101. The outer surface walls between a group of clamping blocks 218 are in contact with the outer surface wall of the protective layer 101. An inner lining layer 102 is fixedly inserted into the inner surface wall of the protective layer 101. A shielding layer 103 is fixedly inserted into the inner surface wall of the inner lining layer 102. A fireproof layer 104 is fixedly inserted into the inner surface wall of the shielding layer 103. A shock-absorbing layer 105 is fixedly inserted into the inner surface wall of the fireproof layer 104. A filling layer 106 is fixedly inserted into the inner surface wall of the shock-absorbing layer 105. A group of first insulating layers 107 are fixedly inserted into the inner surface wall of the filling layer 106. Conductors 108 are fixedly inserted into the inner surface walls of the group of first insulating layers 107. A second insulating layer 109 is fixedly inserted into the inner surface wall of the filling layer 106. A temperature-measuring cable 110 is fixedly inserted into the inner surface wall of the second insulating layer 109. The protective layer 101 is made of polyvinyl chloride material. The inner lining layer 102 is made of rubber material. The shielding layer 103 is woven from copper wires. The fireproof layer 104 is made of polyolefin material. The shock-absorbing layer 105 is made of EVA plastic. The filling layer 106 is made of polyester fiber. The first insulating layer 107 is made of polyvinyl chloride. The first insulating layer 107 is mainly made of cross-linked polyethylene. The group of conductors 108 are all made of high-purity oxygen-free copper. The second insulating layer 109 is made of perfluoroethylenepropylene.

[0035] In this embodiment, the cable protective layer 101 is made of polyvinyl chloride material. With its excellent weather resistance, mechanical strength and chemical stability, it can effectively resist external extrusion and friction, ultraviolet aging, and oil, acid and alkali erosion. Its surface is easy to color for identification and classification, and it is suitable for most fixed laying scenarios. The inner lining layer 102 uses rubber material, and the high elasticity of rubber can be utilized to play a key buffering role inside the cable: absorb mechanical vibration and disperse the bending stress of the conductor 108. At the same time, the dense structure of rubber can assist in blocking the penetration of longitudinal moisture. Its flexible characteristics can also prevent the metal shielding layer 103 and the cable protective layer 101 from rubbing and damaging each other due to thermal expansion and contraction. It is especially suitable for mobile cables such as mine drag cables, robot cables or environments with drastic temperature differences. The combination of the two forms a "rigid outside and flexible inside" collaborative protection system. The cable protective layer 101 resists external attacks, and the rubber inner lining stabilizes the internal structure, jointly extending the service life of the cable. The copper wire braided cable shielding layer 103 is tightly braided into a mesh structure with high-purity copper wire. Since copper has excellent electrical properties and corrosion resistance, it can efficiently shield electromagnetic interference such as external motor noise and wireless signals. At the same time, it can also suppress the leakage of the internal electric field or magnetic field of the cable, avoiding signal crosstalk or equipment malfunction. The braided structure also endows the cable with additional flexibility and tensile strength, protecting the internal conductor 108 from breaking in frequently bent or highly vibrating environments such as automation equipment and medical instruments, and quickly discharging leakage current or static charges through grounding design, significantly improving the system safety and anti-interference ability. It is especially suitable for precision scenarios such as 5G communication base stations and servo motor cables. The cable fireproof layer 104 has modified polyolefin as the core and realizes the low-smoke and halogen-free characteristics by adding components such as aluminum hydroxide and nitrogen-based flame retardants. When encountering an open flame, the fireproof layer 104 can quickly form a carbonized layer to isolate oxygen and release inert gases, cutting off the direct contact between the flame and the cable, preventing the fire from spreading to other areas through the cable channel. Almost no toxic gases such as hydrogen halide are released during the combustion process, which can buy time for personnel evacuation and fire fighting and rescue. It can still maintain physical stability at high temperatures, enabling it to maintain the insulation and conduction functions of the cable in the initial stage of the fire, ensuring the continuous operation of key equipment such as emergency lighting and fire protection systems, and can also prevent molten dripping from igniting surrounding equipment. It is widely used in densely populated places with extremely high fire protection and escape requirements such as subway tunnels, nuclear power plants and high-rise buildings. The cable shock-absorbing layer 105 is made of EVA plastic, which can absorb the high-frequency vibration energy or instantaneous impact force generated during equipment operation, preventing insulation wear, conductor 108 breakage or joint 204 loosening caused by long-term vibration of the cable. The wide temperature range adaptability of EVA can also buffer the thermal stress impact on the inside of the cable caused by sudden external temperature changes. The cable filling layer 106 is made of polyester fiber woven into a bundle or mesh filler, and uses its high strength to evenly fill the gap between the conductor 108 and the insulation layer, avoiding the loosening and deformation of the cable core, ensuring that the cable cross-section remains round, so as to reduce the internal stress concentration during laying, bending or external force extrusion, preventing the damage of the insulation layer 107 and the insulation layer 109 or the displacement of the conductor 108.Particularly applicable to multi-core power cables or complex wiring scenarios, the cable insulation layer 107 is made by modifying polyvinyl chloride resin as the main body with plasticizers and stabilizers. It isolates the conductor 108 from the external environment or other conductors 108 through its high-resistance characteristics, preventing electric leakage, short circuits or arc discharges, avoiding the risks of electric shock to personnel, equipment damage and fires. It is particularly crucial for high-voltage cables, multi-core cables or densely laid scenarios. The acid and alkali resistance and oil resistance of PVC can further protect the conductor 108 from corrosion in humid and oily environments. The smooth surface characteristic also facilitates pipe laying during installation. The cable uses high-purity oxygen-free copper as the conductor 108, which significantly reduces the power transmission loss with its extremely low resistivity, improves energy efficiency. The uniform and dense lattice structure endows excellent ductility and tensile strength, enabling it to withstand the mechanical stress in complex laying and ensuring long-term stability. The oxygen-free process eliminates oxide impurities, giving the conductor 108 strong corrosion resistance, and can still delay oxidation degradation even in humid, salt spray or high-temperature environments, extending the service life.

[0036] Example 3: According to Figures 1 - 3 and Figure 8 As shown, the inner wall of the filling layer 106 is fixedly inserted with an insulation layer 2 109, and the inner wall of the insulation layer 2 109 is fixedly inserted with a temperature-measuring cable 110. The insulation layer 2 109 is made of perfluoroethylene propylene.

[0037] In this embodiment, installing the temperature-measuring cable 110 near the internal conductor 108 of the cable can provide multiple safety guarantees and efficiency improvements for the power system through real-time and accurate temperature monitoring. The temperature-measuring points directly close to the conductor 108 can capture the most real operating temperature data, instantly identify local overheating caused by overload, abnormal contact resistance or insulation aging, and avoid the risk of insulation breakdown or fire caused by temperature accumulation. The insulation layer 2 109 provides a basic electrical isolation function for the temperature-measuring cable 110, preventing electric leakage and short circuits between the temperature-measuring line and the conductor 108 or the external environment, and ensuring the safety and stability of the signal acquisition circuit.

[0038] The working principle of the entire mechanism is as follows: When assembling the cable and the joint 204, first, the protective sleeve 201 is sleeved on the outer surface of the protective layer 101, so that the inner side of the sleeve body forms a contact interface with the conductor group 108 and the temperature-measuring cable 110. When the operator rotates the adjusting wheel 207, the built-in rotating shaft 205 generates a rotary motion in the second moving hole 203, driving the first bevel gear 206 fixed on the surface of the rotating shaft 205 to rotate synchronously. This bevel gear set drives the first bottom gear 209 to rotate coaxially through meshing transmission with the second bevel gear 208. The six meshing second gears 212 distributed on the outer edge of the first gear 209 then generate self-rotation around the axis of the fixed rod 211, thereby driving the third gear 213 connected at the bottom to move synchronously. The six third gears 213 and the linear rack 214 form a meshing transmission assembly, and the rotary motion of the gear set is converted into the linear propulsion of the rack 214. The arc-shaped plate 215 connected to the end of the rack 214 then undergoes a radial displacement towards the protective layer 101. When the clamping block 218 carried by the arc-shaped plate 215 forms a tight fit with the surface of the protective layer 101, the continuously advancing rack 214 forces the spring 217 to compress, and at the same time, it pushes the piston 216 to generate an axial displacement in the glue storage chamber 219. This mechanical action causes the pre-stored liquid insulating glue in the chamber to penetrate the sealing film 221 under pressure and be evenly distributed on the contact surface formed by the protective layer 101, the protective sleeve 201, and the clamping block 218. The solidified glue forms a continuous and dense composite protective layer. This structure has multiple functions: effectively blocking the penetration of environmental moisture, preventing the insulation deterioration of the joint 204 caused by moisture absorption, enhancing the structural rigidity of the connection part, reducing the risk of poor contact caused by mechanical vibration, improving the impact resistance of the joint 204 through stress dispersion, significantly extending the service life of the cable connection device under complex working conditions. The polyvinyl chloride protective layer 101 is made of PVC material to create an outer protection that can resist the molecular chain breakage caused by ultraviolet rays, resist mechanical stress and frictional loss, and have the ability to protect against oil stain / acid-base corrosion due to chemical inertness. The surface can be customized with coloring codes for easy line identification and maintenance management. The inner lining layer 102 absorbs vibration energy through the high-elastic deformation of molecular chains, balances the stress distribution when the multi-conductor 108 is bent, and realizes a longitudinal water-blocking barrier through a dense cross-linked structure, thereby inhibiting the penetration of moisture along the cable core. At the same time, it flexibly isolates the thermal expansion difference friction between the metal shielding layer 103 and the rigid protective layer 101, and is particularly suitable for mobile scenarios such as mining tow cables and robotic arm cables and environments with drastic temperature differences. The shielding layer 103 is woven into a three-dimensional network structure with high-purity copper wires, and uses the high electrical conductivity and corrosion resistance of copper to bidirectionally block external electromagnetic interference and internal electromagnetic leakage, ensuring signal integrity and system safety. The modified polyolefin substrate of the fireproof layer 104 triggers a triple protection mechanism when encountering fire in its aluminum hydroxide / nitrogen-based flame retardant system - the expanded carbonized layer isolates oxygen, releases inert gases to dilute combustibles, inhibits the release of smoke and poisonous gases, and maintains the structural stability at a high temperature of 800 °C, ensuring the emergency power supply and communication link functions in the initial stage of a fire and preventing the secondary disaster of ignition caused by molten droplets.Specifically designed for high-risk and densely populated places such as subway tunnels and data centers, the shock-absorbing layer 105 is composed of EVA plastic. It absorbs high-frequency vibration and impact energy through viscoelastic molecular chains, inhibits fatigue fracture of the conductor 108 and loosening of the joint 204. Its wide-temperature-range characteristic can synchronously buffer thermal stress shocks. The filling layer 106 is uniformly filled with polyester fiber fabric in the gaps of the conductor 108 to maintain the roundness of the cable core, reduce internal stress concentration during laying and bending, prevent damage to the first insulating layer 107 and the second insulating layer 109 or displacement of the conductor 108, and adapt to the complex wiring requirements of multi-core power cables. The first insulating layer 107 is based on a modified PVC resin formula, blocks the risks of electric leakage and short circuit through its high-resistance characteristic, protects the conductor 108 from corrosion in humid environments with acid and alkali resistance and oil resistance characteristics, and optimizes the pipe-passing construction efficiency with its smooth surface. The conductor 108 is made of oxygen-free copper with a purity of ≥99.99%, reduces transmission losses with its extremely low resistivity, and the structure of its dense crystal lattice endows the conductor 108 with high ductility and tensile strength. The oxygen-free process is combined to eliminate oxidation defects. The conductor 108 still maintains corrosion resistance and stable electrical performance in harsh environments such as salt spray and high temperature. Through the complementary physical and chemical properties of each functional layer, a full-dimensional reliability upgrade of mechanical protection, environmental tolerance, electromagnetic purification, fire defense, and energy efficiency optimization is achieved. A temperature-measuring cable 110 is integrated near the conductor 108 inside the cable, and accurate temperature rise data is captured in real time through heat-sensitive measuring points closely attached to the conductor 108, which can immediately diagnose local overheating risks caused by overload, abnormal contact resistance, or deterioration of the second insulating layer 109, and avoid insulation breakdown or fire caused by heat accumulation. The second insulating layer 109 is coated with a high-dielectric-strength material around the temperature-measuring cable 110 to form a double isolation barrier: on the one hand, it blocks the leakage current path between the temperature-measuring line and the live conductor 108, preventing the signal acquisition system from short-circuiting and failing; on the other hand, it resists the intrusion of external environmental moisture and oil stains to interfere with the accuracy of temperature-measuring elements (such as fiber Bragg gratings and thermocouples), ensuring continuous and reliable temperature data.
