Description

Technical Field

[0001] This utility model relates to the field of cable technology, and in particular to a weather-resistant rare earth high-speed rail aluminum alloy armored power cable. Background Technology

[0002] Weather-resistant rare-earth high-speed rail aluminum alloy armored power cable is a power transmission device suitable for complex outdoor environments and special industrial scenarios. Its conductor is made of rare-earth high-speed rail aluminum alloy material. By adding rare earth elements and high-speed rail components to the aluminum alloy, the conductivity and mechanical strength of the material are optimized. At the same time, the outer armor structure, combined with the weather-resistant outer sheath, can effectively resist the effects of various harsh environments such as high temperature, low temperature, humidity, ultraviolet radiation and chemical corrosion. It is widely used in power transmission systems in urban power grid transformation, rail transit, petrochemical and other fields.

[0003] Some cable joints typically consist of an insulating shell, conductive connectors, sealing components, and armored fixing structures. Their working principle is to mechanically connect and electrically conduct the conductors of two cable segments through conductive connectors, with the insulating shell wrapping around the connection area to ensure insulation performance. The sealing components use sealing rings or sealant to achieve waterproof and moisture-proof functions, and the armored fixing structure uses metal clamps or crimping rings to fix the armor layer of the cable to prevent damage to the joint due to external pulling forces, thereby achieving a stable connection and power transmission between the two cable segments.

[0004] In some technologies, the structural design for cable connections has significant limitations. When cables need to be extended, the connection methods often rely on a single crimping or welding process, lacking convenient detachable connection mechanisms. This makes it difficult to quickly and stably connect short cables to new cables, and once the connection is completed, it is difficult to disassemble, causing great inconvenience for later maintenance and replacement. At the same time, some connection interfaces require the use of special tools, which is cumbersome and time-consuming, and cannot meet the connection efficiency requirements for rapid installation and emergency repairs. This limits the application of cables in temporary wiring and flexible expansion scenarios. To address these issues, a weather-resistant rare-earth high-speed rail aluminum alloy armored power cable is proposed. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A weather-resistant rare earth high-speed rail aluminum alloy armored power cable includes an outer sheath, an armor layer inside the outer sheath, a disassembly and assembly mechanism inside the armor layer, and a pressing and docking mechanism fixedly connected to the rear side of the outer sheath.

[0008] The disassembly and assembly mechanism includes three fixing rings. The outer side of the fixing ring is located inside the armor layer. The bottom of the fixing ring is rotatably connected to a connecting shaft. The top of the fixing ring is threaded with a bolt.

[0022] A sleeve is fixedly connected to the front side of the outer sheath, and a sheath is fixedly connected inside the sleeve.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by applying downward pressing force to the button, the force is transmitted to the connecting rod, causing the connecting rod to move axially towards the bottom of the structure.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a weather-resistant rare-earth high-speed rail aluminum alloy armored power cable, comprising an outer sheath 1. The outer sheath 1, as the outermost protective structure of the cable, can directly contact the external environment. Its main function is to resist external mechanical wear, prevent moisture penetration, and block dust and other impurities from entering the cable. At the same time, it can also buffer external impact forces to a certain extent, effectively protecting the internal structure of the cable. An armor layer 2 is provided inside the outer sheath 1. The armor layer 2 wraps around the outside of the core structure of the cable. Its main function is to enhance the overall mechanical strength of the cable, enabling it to withstand greater tensile, compressive, and torsional forces, and preventing damage to the internal structure of the cable due to external forces during laying, installation, or use. It can also provide the cable with a certain degree of impact and compression resistance, improving the cable's durability in complex environments.

[0035] The armor layer 2 is equipped with a disassembly and assembly mechanism 9, which is a key structure for realizing the segmented connection and disassembly of the cable. Through the coordinated action of its components, the cable can be easily connected, installed, and disassembled for maintenance. This ensures that when the cable needs to be extended or repaired, the corresponding part can be operated quickly without large-scale modifications to the entire cable. A pressing and docking mechanism 10 is fixedly connected to the rear side of the outer sheath 1. The pressing and docking mechanism 10 is connected to the rear side of the cable outer sheath 1 and is mainly used to realize the quick connection and separation of the cable with other equipment or another section of cable. Connection or disassembly can be completed by a simple pressing operation, which greatly improves the operational efficiency of the cable during installation and interface replacement. It is especially suitable for scenarios that require frequent interface docking. The disassembly and assembly mechanism 9 includes three fixing rings 91. The three fixing rings 91 cooperate with each other to form the basic support structure of the disassembly and assembly mechanism 9. They are distributed at a certain interval inside the armor layer 2, which can stably position the other components of the disassembly and assembly mechanism 9 in the preset position inside the cable. At the same time, it forms a ring support for the internal connecting components to prevent the components from shifting when the cable is subjected to external forces.

[0036] The retaining ring 91 is externally positioned inside the armor layer 2. This installation method allows the retaining ring 91 to fit tightly with the armor layer 2. The armor layer 2 provides external support and restraint for the retaining ring 91, preventing it from shaking inside the cable. The retaining ring 91, through its structural strength, further enhances the stability of the internal space of the armor layer 2, ensuring that the entire assembly / disassembly mechanism 9 can be stably positioned in its working position. A connecting shaft 92 is rotatably connected to the bottom of the retaining ring 91. The connecting shaft 92 is connected to the bottom of the retaining ring 91, and its main function is to enable connection and relative rotation between adjacent retaining rings 91, allowing the three retaining rings 91 to form a movable structure. The overall structure allows for appropriate angle adjustment between the fixing rings 91 via the connecting shaft 92 when the cable bends or twists, preventing excessive pulling or squeezing of the internal connecting components of the disassembly and assembly mechanism 9 due to cable deformation. The top of the fixing ring 91 is threaded with a bolt 93, which is installed on the top of the fixing ring 91 via a threaded connection. After the fixing ring 91 is installed in place, the bolt 93 is tightened, and its lower end can abut against the inner wall of the armor layer 2 or other corresponding limiting structures, thereby firmly fixing the fixing ring 91 in the current position, preventing the fixing ring 91 from axially moving inside the cable, and ensuring the overall installation stability of the disassembly and assembly mechanism 9.

[0037] The fixing ring 91 has three isolation plates 94 fixedly connected inside. These three isolation plates 94 are evenly distributed at a certain angle inside the fixing ring 91, dividing the internal space of the fixing ring 91 into three independent areas. Each area corresponds to a connecting component. Their main function is to physically isolate the connecting components, preventing mutual interference between different connecting components. They also provide a certain degree of buffering and protection for the connecting components when the cable is subjected to external impact, reducing collision damage between components. A protective sleeve 95 is installed inside the fixing ring 91, located within the space separated by the isolation plates 94. The protective sleeve 95 completely covers the outside of the connecting components, providing insulation and heat protection to prevent electrical conductivity between the connecting components and the metal structure such as the fixing ring 91. It also blocks external temperature changes from affecting the internal components of the connecting components. The conductor connection is affected, ensuring the stability of the conductor connection. The protective sleeve 95 has three connecting components 96 inside, which correspond to three independent spaces inside the protective sleeve 95. Each connecting component 96 is used to connect the corresponding conductor in a section of cable. The three connecting components 96 cooperate with each other to complete the connection of multiple conductors at the same time, ensuring that multiple groups of conductors inside the cable are independent and do not interfere with each other during the connection process, ensuring the orderly transmission of power. The connecting component 96 includes a connecting shell 961, which is the main structure of the connecting component 96. Its interior forms a closed space to accommodate the conductor parts of the two cable sections that need to be connected, providing a stable operating and accommodating environment for the conductor connection. At the same time, the connecting shell 961 also provides a certain degree of protection for the internal conductor connection parts, preventing external impurities from entering and affecting the conductivity of the conductor.

[0038] The connecting shell 961 is externally and fixedly connected to the inside of the protective sleeve 95. This fixed connection method ensures that the connecting shell 961 is stably positioned within the protective sleeve 95. The protective sleeve 95 provides external support and protection for the connecting shell 961, preventing displacement when the cable shakes or deforms. This ensures that the conductor maintains a stable connection within the connecting shell 961. Multiple bolts 962 are threaded onto the outer wall of the connecting shell 961. These bolts are evenly distributed on the outer wall. When the conductors of the two cable segments are inserted into the connecting shell 961, tightening the bolts 962 allows their ends to extend into the connecting shell 961 and press against the conductor, thus firmly fixing the conductor inside the connecting shell 961. To ensure tight contact between the two conductors and achieve a good conductive connection, preventing the conductors from loosening inside the connecting shell 961 and affecting power transmission, a fixing sleeve 963 is threaded to both ends of the connecting shell 961. The fixing sleeve 963 is installed at the left and right ends of the connecting shell 961 respectively. After the conductor of the cable passes through the fixing sleeve 963 and enters the connecting shell 961, the fixing sleeve 963 is rotated to make it tightly connected to the connecting shell 961. The fixing sleeve 963 can fill the gap between the conductor and the end of the connecting shell 961, playing a role in sealing and fixing, preventing external dust, moisture and other impurities from entering the interior through the end gap of the connecting shell 961, and also further restricting the axial movement of the conductor inside the connecting shell 961, enhancing the stability of the connection.

[0039] Reference Figure 4 The pressing and docking mechanism 10 includes a connecting ring 101, which is the basic component for connecting the pressing and docking mechanism 10 to the cable body. Its inner side is fixedly connected to the outer side of the outer sheath 1, which can stably fix the pressing and docking mechanism 10 in the preset position of the cable, providing a solid support foundation for subsequent interface docking. It also plays a role in connection and transition, making the connection between the pressing and docking mechanism 10 and the outer sheath 1 tight and preventing loosening or displacement during docking operation. The front side of the connecting ring 101 is detachably connected to the interface base 102. The interface base 102 is the key load-bearing structure for realizing the docking of the cable with external equipment or other cables. It is detachably connected to the connecting ring 101, which is convenient for disassembly and replacement when the interface base 102 is damaged or when different types of interfaces need to be replaced. The interior of the interface base 102 provides installation space for other components and is also the main stress part during docking, ensuring the stability of the docking process.

[0040] An upper outer shell 103 is provided inside the interface base 102. The upper outer shell 103 is a protective and support structure for the upper part of the pressing docking mechanism 10. It is fixedly installed inside the interface base 102 and can protect the internal components such as buttons and connecting rods, preventing external impurities from entering and affecting the normal operation of the components. At the same time, it also provides guidance and limit for the sliding of the button, ensuring that the button can only move in a preset direction and ensuring the accuracy of operation. A button 104 is slidably connected to the top of the upper outer shell 103. The button 104 is the direct actuating component for pressing operation. The user triggers the entire docking or disassembly process by pressing or releasing the button 104. Its sliding connection with the upper housing 103 allows the button 104 to slide up and down along the top of the upper housing 103 when force is applied, transmitting the user's operating force to the connecting rod below, thereby driving the subsequent components to move. The bottom of the button 104 is fixedly connected to the connecting rod 105, which is the force transmission hub. Its top is fixedly connected to the button 104, which can transmit the pressing force of the button 104 to the relevant components below. When the button 104 is pressed or reset, the connecting rod 105 will move synchronously, and through its own movement, it will drive the fixed bead and other components to change their state, thereby realizing the locking and unlocking of the interface.

[0041] A spring 106 is slidably connected to the outer wall of the connecting rod 105. The spring 106 is sleeved on the outer wall of the connecting rod 105, and its two ends abut against the button 104 and the upper outer shell 103, respectively. When the button 104 is pressed, the spring 106 is compressed and stores elastic potential energy. When the button 104 is released, the spring 106 releases elastic potential energy, generating an upward elastic force to push the button 104 and the connecting rod 105 back to their initial state, preparing the entire mechanism for the next operation. A lower outer shell 107 is fixedly connected to the bottom of the upper outer shell 103. The lower outer shell 107 and the upper outer shell 103 together constitute the internal protective shell of the pressing and docking mechanism 10. It is fixedly connected to the bottom of the upper outer shell 103, providing installation space and protection for internal components such as fixing beads and buckle bases. At the same time, it cooperates with the upper outer shell 103 to form a closed internal environment, preventing dust, moisture, etc. from entering and affecting the normal operation of the components. A retaining bead 108 is slidably connected to the inner wall of the outer shell 107. The retaining bead 108 is a key component for locking and unlocking the interface. It can slide along the inner wall of the lower outer shell 107 under the action of the connecting rod 105. When the interface needs to be locked, the retaining bead 108 will extend outward and be inserted into the groove of the snap-fit ​​base to fix the interface. When the interface needs to be unlocked, the retaining bead 108 will retract inward and disengage from the groove to release the locked state, ensuring that the interface can be smoothly separated or connected. A snap-fit ​​base 109 is fixedly connected inside the lower outer shell 107. The snap-fit ​​base 109 is a component that cooperates with the retaining bead 108 to achieve locking. It has a groove inside that matches the retaining bead 108. When the retaining bead 108 is inserted into the groove, it can firmly lock the interface to prevent accidental dislodgement during use and ensure the stability of the connection. At the same time, the snap-fit ​​base 109 also provides a reference for positioning during connection to ensure that the interface can be accurately connected.

[0042] Reference Figure 1 , Figure 2 , Figure 5The armor layer 2 contains a shielding layer 3, which wraps around the inner side of the armor layer 2. Its main function is to isolate the interference of external electromagnetic signals on the transmission of the internal conductors of the cable, and at the same time, to block the electromagnetic radiation generated inside the cable from spreading outward, so as to avoid affecting other electronic equipment in the vicinity and ensure the stability and purity of power or signal transmission. The shielding layer 3 contains an insulation layer 4, which is located inside the shielding layer 3 and is in direct contact with the shielding layer 3. Its core function is to block abnormal current conduction, prevent short circuits between the internal conductors of the cable and the external structure, and isolate different conductors from each other, so as to ensure that each conductor can transmit power or signals independently and avoid signal crosstalk or power leakage. The insulation layer 4 contains a heat-conducting layer 5, which is located inside the insulation layer 4. It can quickly absorb the heat generated by the conductors during the operation of the cable and conduct it to the outside, and dissipate it to the surrounding environment through the outer sheath and other structures, so as to prevent heat from accumulating inside the cable and causing the temperature to be too high, thereby preventing the insulation layer from aging and failing due to overheating, and ensuring the safe operation and service life of the cable.

[0043] The heat-conducting layer 5 contains three explosion-proof layers 6, which are evenly distributed within the heat-conducting layer 5. Each explosion-proof layer 6 corresponds to a conductor-related structure. Its main function is to enhance the cable's resistance to impact and compression. When the cable is subjected to severe external impact or compression, the explosion-proof layer 6 can absorb and buffer the impact force, reducing the damage to the internal conductor and insulation structure, and protecting the integrity of the core transmission components. Inside the explosion-proof layer 6, there is an insulating sleeve 7. The insulating sleeve 7 fits tightly against the inner side of the explosion-proof layer 6 and is the most direct insulation protection structure for the conductor 8. It can further enhance the insulation isolation effect on the conductor, prevent the conductor from contacting the explosion-proof layer and other structures, and prevent leakage risks. At the same time, it can also restrain the conductor to a certain extent, preventing the conductor from shaking or shifting inside the cable. Inside the insulating sleeve 7, there is a conductor 8. The conductor 8 is the core component for the cable to realize power or signal transmission. It runs through the inside of the insulating sleeve 7 and transmits power or signals from one end to the other through its own conductivity. It is the key to the realization of the entire cable function, and its structural state directly affects the transmission efficiency and stability.

[0044] A sleeve 11 is fixedly connected to the front side of the outer sheath 1. The sleeve 11 is fixed to the front end of the outer sheath 1 and mainly serves to extend protection. It can reinforce and protect the end of the cable, prevent the end of the cable from being damaged by external friction and collision, and also provide a stable transition structure for the connection of the cable with other equipment, which facilitates the connection operation. A sheath 12 is fixedly connected inside the sleeve 11. The sheath 12 is located inside the sleeve 11 and together with the sleeve 11, it forms a double protection. It tightly wraps around the outside of the relevant structure inside the sleeve 11, further enhancing the insulation and protection effect of the core components of the cable end, preventing moisture, dust and other impurities from entering through the gap between the sleeve and the internal structure, and ensuring the safety and reliability of the cable end connection.

[0045] Working principle: During cable installation, there may be situations where the cable is too short and a new cable needs to be connected. When a connection is needed, the conductors 8 of the two cable sections are stripped and connected into the connecting shell 961. The excess gap is blocked with a fixing sleeve 963. Then, bolts 962 are driven into the pre-drilled threaded holes on the connecting shell 961 to fix the conductors 8 together. Then, a protective sleeve 95 is wrapped around the outside of the connecting shell 961 for insulation and heat insulation. Then, a fixing ring 91 is fitted on the outside. The isolation plate 94 in the fixing ring 91 will separate three connecting shells 961, which serves to fix the connection and also to better dissipate heat. Finally, the fixing ring 91 is firmly fixed with bolts 93 to prevent external vibration.

[0046] During cable use, there are situations where the interface needs to be replaced. When the interface needs to be replaced, press button 104. The bottom connecting rod 105 will move downwards due to the pressure of button 104. Then, the bottom fixing bead 108 will move inwards due to the slope of the bottom of the connecting rod 105, so that it will not be stuck by the snap-fit ​​base 109, and can be pulled out smoothly. Then, the spring 106 at the top of the connecting rod 105 will automatically drive button 104 and connecting rod 105 back to the center because there is no pressing force. After the interface is replaced, press button 104 again, so that the upper fixing bead 108 falls to the bottom of the connecting rod 105 and is placed into the snap-fit ​​base 109. After that, the spring 106 returns to the center again, so that the fixing bead 108 is locked in the groove of the snap-fit ​​base 109, and the connection is completed.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
