Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, and in particular to a device for connecting a pre-branched flexible busbar and a branch cable. Background Technology

[0002] With the rapid development of modern power systems, the reliability and flexibility of power distribution networks have become increasingly important. Traditional power distribution methods typically involve wrapping branch cables around the main conductor, allowing the conductive parts at the ends to overlap and conduct electricity.

[0003] However, this branch cable connection method generally requires bending the conductive part of the branch cable, which is inconvenient for disassembly and assembly. In addition, repeated disassembly and assembly will reduce the service life of the branch cable and the main body. During the splicing process of the branch cable and the main body, it is often subject to the limitations of space, load changes and installation conditions, resulting in low splicing efficiency and increased labor intensity. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a pre-branched flexible busbar and branch cable splicing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: a pre-branched flexible busbar and branch cable splicing device is constructed, including a fixing component and an insulating protective component installed on the main body. The fixing component holds at least one branch conductor against the main body, and the insulating protective component covers the periphery of the fixing component. The fixing component includes a clamping component and a locking component. The clamping component is detachably installed on the main body through the locking component. The clamping component presses the branch conductor against the main body. The clamping component is provided with at least one limiting groove to restrict the movement of the branch conductor.

[0006] Furthermore, the depth of the limiting groove is less than the diameter of the branch conductor.

[0007] Furthermore, the clamping member is a first clamping plate, and the periphery of the first clamping plate is in contact with the main body.

[0008] Furthermore, the clamping member includes a second clamping plate and a third clamping plate, the second clamping plate being disposed on one side of the main body, the third clamping plate being disposed on the other side of the main body, and the branch conductor being disposed between the second clamping plate and / or the third clamping plate and the main body.

[0009] Furthermore, the second clamping plate and the third clamping plate together form the limiting groove.

[0010] Furthermore, the third clamping plate is provided with a limiting groove for accommodating the main body, and the second clamping plate is provided with a protrusion that extends into the limiting groove to press the branch conductor onto the main body, and the limiting groove is provided on the protrusion.

[0011] Furthermore, the third clamping plate is provided with an extrusion slope, the second clamping plate is provided with a receiving groove for accommodating the extrusion slope, and the branch conductor is disposed between the extrusion slope and the main body.

[0012] Furthermore, the locking element is a bolt or a snap fastener.

[0013] Furthermore, the insulating protective component includes: a first housing, a second housing, and a connector. The first housing is mounted on the second housing via the connector. A storage cavity for storing the fixing component and the main conductor is provided between the first housing and the second housing. The first housing and / or the second housing are provided with through holes that allow the branch conductor to pass through. The connector is a bolt or a clip.

[0014] Furthermore, a transparent observation window is provided on the first housing and / or the second housing.

[0015] The following are the beneficial effects of implementing this utility model: This application utilizes a fixing component and an insulating protective element installed on the main body. The fixing component holds at least one branch conductor against the main body, while the insulating protective element covers the periphery of the fixing component. The fixing component includes a clamping element and a locking element. The clamping element is detachably mounted on the main body via the locking element, and the clamping element presses the branch conductor against the main body. This clamping element quickly presses the branch conductor against the main body, ensuring a tight fit between the branch conductor and the conductive portion of the main body, thus overlapping the branch conductor onto the main body. The entire process does not require bending or damaging the branch conductor. The cooperation between the clamping and locking elements reduces space constraints, facilitates assembly and disassembly, extends the service life of both the branch conductor and the main body, and improves operational efficiency and labor intensity. Furthermore, because the overlap point uses a non-destructive connection method, both the branch conductor and the main body can be disassembled and reused multiple times. When the production line is adjusted or the load changes, only the branch path needs to be reconfigured, avoiding material waste and system rebuilding, making it suitable for a wider range of operating environments.

[0022] Please see Figures 1 to 3The pre-branched flexible busbar and branch cable splicing device in the first embodiment of this utility model includes a fixing component 2 and an insulating protective component 3 installed on the main body 1. The fixing component 2 holds at least one branch conductor 4 against the main body 1, and the insulating protective component 3 covers the periphery of the fixing component 2. The fixing component 2 includes a clamping component 21 and a locking component 22. The clamping component 21 is detachably installed on the main body 1 through the locking component 22. The clamping component 21 presses the branch conductor 4 against the main body 1, and the clamping component 21 is provided with at least one limiting groove 23 to restrict the movement of the branch conductor 4.

[0023] This application utilizes a fixing component 2 and an insulating protective element 3 mounted on the main body 1. The fixing component 2 holds at least one branch conductor 4 against the main body 1, and the insulating protective element 3 covers the periphery of the fixing component 2. The fixing component 2 includes a clamping member 21 and a locking member 22. The clamping member 21 is detachably mounted on the main body 1 via the locking member 22, and the clamping member 21 presses the branch conductor 4 against the main body 1. After removing the insulation layer from the main conductor 1 and the branch conductor 4, the branch conductor 4 is pressed tightly against the main conductor 1. Then, the clamping member 21 is pressed against the outside of the branch conductor 4, and the locking member 22 is used to lock the clamping member 21 onto the main conductor 1. The squeezing force generated by the locking member 22 on the clamping member 21 acts on the branch conductor 4, thereby quickly pressing the branch conductor 4 onto the main conductor 1 using the clamping member 21. This ensures that the conductive parts of the branch conductor 4 and the main conductor 1 are tightly bonded together, thus overlapping the branch conductor 4 onto the main conductor 1. The entire process does not require bending or damaging the branch conductor 4. The cooperation between the clamping member 21 and the locking member 22 reduces space constraints, facilitates assembly and disassembly, extends the service life of the branch conductor 4 and the main conductor 1, and also simplifies operation, improves the efficiency of overlapping, and reduces labor intensity. Because the overlapping point uses a non-destructive connection method, both the branch conductor 4 and the main conductor 1 can be disassembled and reused multiple times. When production lines are adjusted or loads change, only branch paths need to be reconfigured, avoiding material waste and system rebuilding, making it suitable for more usage environments.

[0024] This application provides at least one limiting groove 23 on the clamping member 21 to restrict the movement of the branch conductor 4. The limiting groove 23 allows the clamping member 21 to press the branch conductor 4 onto the main body 1, reducing misalignment and further improving the efficiency of the overlap. This facilitates the installation of the branch conductor 4 at the center of the main body 1, increases conductivity, simplifies operation, and reduces labor intensity. The limiting groove 23 also reduces damage to the branch conductor 4, extends its service life, increases the labor intensity between the branch conductor 4 and the main body 1, and improves the tensile strength of the overlap point, making it suitable for more application environments and extending its service efficiency.

[0025] Among them, the insulating protective component 3, which covers the periphery of the fixing component 2, is used after the clamping component 21 firmly presses the branch conductor 4 onto the main body 1. The insulating protective component 3 covers the periphery of the fixing component 2, which can provide a certain protection for the fixing component 2 and the joint point, extend the service life, improve the stability of conductivity, and improve safety through its insulating properties, making it suitable for more usage environments.

[0026] The core conductor of the main conductor 1 can be made of T2 annealed copper (copper content ≥99.95%), a material with extremely high electrical and thermal conductivity. Due to its extremely low impurity content and special annealing process, T2 annealed copper achieves extremely low resistivity and excellent thermal conductivity, significantly reducing line losses and supporting efficient transmission of large currents. Simultaneously, its excellent thermal conductivity helps to quickly dissipate heat generated during operation, effectively suppressing the temperature rise of the main conductor 1, thereby improving the energy efficiency of the entire power system, extending equipment lifespan, and reducing the risk of failures caused by overheating. For insulation, the main conductor 1 typically employs an integral extrusion wrapping process, using high-performance insulating materials such as cross-linked polyethylene (XLPE), thermoplastic polyolefin (TPE), or silicone rubber to form a continuous, uniform, and seamless insulation layer, effectively resisting the risks of electric shock and short circuits. To cope with harsh environments, its insulation layer and sheath are often equipped with UV-resistant, ozone-resistant and flame-retardant agents (such as halogen-free flame retardants), and anti-corrosion coatings (such as tin plating and special polymer coatings) are integrated through multi-layer co-extrusion technology, enabling it to work stably for a long time in environments with high humidity, high temperature or chemical corrosive substances, meeting the stringent requirements of various industries such as petroleum, chemical, and offshore platforms for power equipment.

[0027] The branch conductor 4 typically employs a multi-strand ultra-fine oxygen-free copper wire precision stranding structure, greatly improving bending performance. The insulation layer uses special elastomer materials (such as TPE, EPR, or silicone rubber), providing excellent flexibility and resistance to repeated bending fatigue while ensuring insulation strength. In terms of structural design, the cable utilizes symmetrical cabling technology and short-pitch stranding process, ensuring uniform internal stress distribution and preventing twisting deformation. Furthermore, the application of braided reinforcement layers or spiral tensile elements effectively protects the internal structure while providing cable flexibility, preventing damage to the core during bending. These technical measures enable the branch conductor 4 to easily traverse confined spaces, bypass obstacles, and closely adhere to installation surfaces, greatly improving the ease of deployment and adaptability in complex industrial and commercial environments, and providing significant advantages for subsequent line adjustments and maintenance.

[0028] Please see Figures 1 to 3 In some embodiments, the depth of the limiting groove 23 is less than the diameter of the branch conductor 4.

[0029] In this application, the depth of the limiting groove 23 is less than the diameter of the branch conductor 4. After the branch conductor 4 is placed into the limiting groove 23, the branch conductor 4 will extend beyond the surface of the clamping member 21. The clamping member 21 can more firmly press the branch conductor 4 onto the main body 1, thereby improving the strength of the overlap point, making it suitable for more usage environments and extending its service life. After the clamping member 21 presses the branch conductor 4 onto the main body 1, the branch conductor 4 will deform and fit more tightly with the main body 1, thereby improving conductivity and making it suitable for installation environments with limited space or side leads.

[0030] Please see Figures 1 to 3 In some embodiments, the clamping member 21 is a first clamping plate 211, and the periphery of the first clamping plate 211 is in contact with the main body 1.

[0031] This application uses a clamping member 21 as a first clamping plate 211, with its four sides in contact with the main body 1. The first clamping plate 211 can be made of a conductive material. When the first clamping plate 211 presses the branch conductor 4 onto the main body 1, the contact between the first clamping plate 211 and the main body 1 increases the current-carrying area between the branch conductor 4 and the main body 1, thereby improving conductivity and power transmission stability. This makes it suitable for more application environments and simplifies operation. The locking member 22 can be a screw. Multiple through holes are provided on the first clamping plate 211 to allow the screw tip to pass through. After passing through the first clamping plate 211, the screw tip enters the main body 1, further improving conductivity and making operation simpler and more convenient, thus increasing the efficiency of the connection. This structure can apply constant pressure to ensure a tight fit between the contact surfaces, effectively reducing contact resistance and avoiding overheating problems caused by loosening.

[0032] Among them, multiple branch conductors 4 can be simultaneously pressed onto the main body 1 by the clamping member 21, which further improves the efficiency of overlapping, facilitates operation, and reduces labor intensity.

[0033] Please see Figure 4 In some embodiments, the clamping member 21 includes a second clamping plate 212 and a third clamping plate 213. The second clamping plate 212 is disposed on one side of the main body 1, and the third clamping plate 213 is disposed on the other side of the main body 1. The branch conductor 4 is disposed between the second clamping plate 212 and / or the third clamping plate 213 and the main body 1.

[0034] This application uses a second clamping plate 212 positioned on one side of the main body 1 and a third clamping plate 213 positioned on the other side of the main body 1. The branch conductor 4 is positioned between the second clamping plate 212 and / or the third clamping plate 213 and the main body 1. By using the second clamping plate 212 and the second clamping plate 212 to clamp the main body 1 in the middle, damage to the main body 1 during overlapping can be reduced, extending its service life. By using the second clamping plate 212 and the second clamping plate 212 to clamp the main body 1 in the middle, the locking member 22 is fixed by a long bolt, which can further increase the contact area between the branch conductor 4 and the main body 1, thereby improving conductivity, current carrying capacity, and suitability for high current branches. It also enables rapid installation and is particularly suitable for power distribution occasions with tight schedules, limited space, or frequent adjustments.

[0035] By using the clamping method of the second clamping plate 212 and the third clamping plate 213, the force on the overlapping point can be distributed when the main body 1 is stretched, reducing the damage to the main body 1, extending its service life, and providing more stable power transmission.

[0036] The second clamping plate 212 and the third clamping plate 213 can be clamped on the main body 1 from the left and right or from the top and bottom. Different clamping methods can be selected according to the actual installation environment, thus making it suitable for more installation scenarios and expanding the scope of use.

[0037] Please see Figure 6 In some embodiments, the second clamping plate 212 and the third clamping plate 213 are arranged to form a limiting groove 23.

[0038] This application utilizes a second clamping plate 212 and a third clamping plate 213 to form a limiting groove 23. When the second clamping plate 212 and the third clamping plate 213 form the limiting groove 23, the branch conductor 4 can be placed between the second clamping plate 212 and the third clamping plate 213, and then fixed with bolts. This allows the limiting groove 23 formed by the second clamping plate 212 and the third clamping plate 213 to clamp the branch conductor 4. Then, the locking member 22 is used to secure the second clamping plate 212 and the third clamping plate 213 together. 13 is fixed on the main body 1, thereby causing the second clamping plate 212 and the third clamping plate 213 to press the branch conductor 4 onto the main body 1, reducing the difficulty of operation. When pressing the branch conductor 4 onto the main body 1, it can prevent the branch conductor 4 from being misaligned, making the branch conductor 4 closer to the center of the main body 1, improving the conductivity efficiency, and can further fix the branch conductor 4, improving the connection strength of the branch conductor 4 and the main body 1, making it suitable for more usage environments and extending its service life.

[0039] Please see Figure 5In some embodiments, the third clamping plate 213 is provided with a limiting groove 214 for accommodating the main body 1, and the second clamping plate 212 is provided with a protrusion 215 that extends into the limiting groove 214 to press the branch conductor 4 onto the main body 1, and the limiting groove 23 is provided on the protrusion 215.

[0040] This application features a limiting groove 214 on the third clamping plate 213 to accommodate the main body 1, and a protrusion 215 on the second clamping plate 212 that extends into the limiting groove 214 to press the branch conductor 4 onto the main body 1. A limiting groove 23 is provided on the protrusion 215. The limiting groove 214 enhances the connection strength between the third clamping plate 213 and the main body 1, further improving stability. The protrusion 215 increases the pressing force of the second clamping plate 212 on the branch conductor 4, making the connection between the branch conductor 4 and the main body 1 more secure, thereby improving conductivity and the stability of power transmission. Through the cooperation of locking member 22 with limiting groove 214 and protrusion 215, protrusion 215 can squeeze branch conductors 4 of different diameters onto main body 1, expanding the applicable range. Limiting groove 23 is set on protrusion 215. During the process of protrusion 215 squeezing branch conductor 4 onto main body 1, limiting groove 23 can reduce the misalignment of branch conductor 4, making the overlap position of branch conductor 4 and main body 1 more accurate, easier to operate, and improving conductivity. It is suitable for straight section branches with sufficient space.

[0041] Please see Figure 7 In some embodiments, the third clamping plate 213 is provided with an extrusion slope 216, the second clamping plate 212 is provided with a receiving groove 217 for accommodating the extrusion slope 216, and the branch conductor 4 is disposed between the extrusion slope 216 and the main body 1.

[0042] This application has a pressing slope 216 provided on the third clamping plate 213, and a receiving groove 217 provided on the second clamping plate 212 to accommodate the pressing slope 216. The branch conductor 4 is disposed between the pressing slope 216 and the main body 1. The second clamping plate 212 and the third clamping plate 213 are arranged on the left and right sides of the main body 1. Then, the branch conductor 4 is placed between the extrusion slope 216 and the main body 1. Then, the second clamping plate 212 and the third clamping plate 213 are brought closer to the main body 1 by the locking member 22. During this process, the branch conductor 4 remains unchanged. The extrusion slope 216, which moves in the receiving groove 217, will slowly extrude the branch conductor 4 onto the main body 1 according to the inclination angle of the slope. This can reduce the damage to the branch conductor 4 during the extrusion process and extend its service life. It can also extrude branch conductors 4 of different diameters onto the main body 1 simultaneously. The smaller the diameter of the branch conductor 4, the closer it is to the extrusion slope 216 on the side of the second clamping plate 212. This makes it suitable for more usage environments and expands the scope of use. It can simultaneously connect multiple branch conductors 4 to the main body 1, further improving the efficiency of connection and facilitating operation.

[0043] Please see Figures 1 to 7 In some embodiments, the locking element 22 is a bolt or a snap fastener.

[0044] This application utilizes either a bolt or a clip for the locking element 22. When the locking element 22 is a bolt, it facilitates adjustment of the compressive strength between the branch conductor 4 and the main body 1. This reduces damage to both the main body 1 and the branch conductor 4 while securely attaching the branch conductor 4 to the main body 1, making it suitable for a wider range of applications and simplifying manufacturing, thus reducing costs. When the locking element 22 is a clip, it quickly secures the clamping element 21 to the main body 1, improving installation efficiency and making operation simpler and less strenuous. Furthermore, it ensures that the clamping element 21 is held in place with the same force each time, further reducing damage to the main body 1 and the branch conductor 4 after repeated disassembly and reassembly, extending service life, and reducing maintenance costs.

[0045] Please see Figures 1 to 7 In some embodiments, the insulating protective component 3 includes: a first housing 31, a second housing 32 and a connector 33. The first housing 31 is mounted on the second housing 32 via the connector 33. A storage cavity 34 for storing the fixing component 2 and the main body 1 is provided between the first housing 31 and the second housing 32. A through hole 35 is provided on the first housing 31 and / or the second housing 32 to allow the branch conductor 4 to pass through.

[0046] This application involves mounting a first housing 31 onto a second housing 32 via a connector 33. A storage cavity 34 for storing the fixing component 2 and the main body 1 is provided between the first housing 31 and the second housing 32. The first housing 31 and / or the second housing 32 are provided with through holes 35 allowing the branch conductor 4 to pass through. After the clamping member 21 firmly presses the branch conductor 4 onto the main body 1, the first housing 31 and the second housing 32 cover the periphery of the fixing component 2, allowing the second clamping plate 212 and the third clamping plate 213 to be stored in the storage cavity 34. Then, the connector 33 is used to connect the first housing 31 and the second housing 32... The fixing component 2 is mounted on the main body 1. The first housing 31 and the second housing 32, which surround the fixing component 2, are limited by the shape of the fixing component 2, thus keeping the first housing 31 and the second housing 32 relatively stationary with respect to the fixing component 2. This indirectly mounts the first housing 31 and the second housing 32 onto the main body 1. By placing the connection point between the fixing component 2 and the main body 1 and the branch conductor 4 in the storage cavity 34, external interference to the fixing component 2 and the connection point can be reduced, extending their service life. It can also improve the stability and safety of conductivity, making it suitable for more usage environments. The first housing 31 and / or the second housing 32 are provided with through holes 35 that allow the branch conductor 4 to pass through. A sealing gasket can be placed between the through hole 35 and the branch conductor 4 to improve the sealing of the storage cavity 34, further reducing the entry of impurities and extending its service life.

[0047] The protection of the joint points by the first housing 31 and the second housing 32 reduces the use of insulating tape, thereby reducing material waste during each disassembly and assembly, reducing maintenance costs, and making it easier to implement insulation isolation of the joint points, further improving installation efficiency.

[0048] The connector 33 can be either a bolt or a clip. When the connector 33 is a bolt, the cost is lower, it is easier to manufacture, and it is suitable for more usage environments. When the connector 33 is a clip, the first housing 31 can be quickly installed onto the second housing 32, further improving installation efficiency, making operation easier, and reducing labor intensity.

[0049] Please see Figures 1 to 7 In some embodiments, a transparent viewing window 36 is provided on the first housing 31 and / or the second housing 32.

[0050] This application incorporates a transparent observation window 36 on the first housing 31 and / or the second housing 32. This allows inspection personnel to examine the joints without opening the insulating protective component 3, improving inspection efficiency and enabling timely handling in case of danger. Furthermore, test interfaces can be provided on the first housing 31 and / or the second housing 32, allowing for inspection of internal connections without disassembling the housings, and connection of instruments to measure parameters such as temperature and resistance, thus enabling status monitoring and early warning.

[0051] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
