Description

Technical Field

[0001] This invention relates to the field of busbar trunking, and more specifically, to a modular busbar trunking and its assembly method. Background Technology

[0002] Busbar trunking is a high-efficiency power distribution device for transmitting current, consisting of a metal casing (usually aluminum alloy or steel), conductor bars, and insulation materials. It offers advantages such as high current carrying capacity, high protection level, flexible power distribution, and convenient installation and maintenance. It is widely used in power supply and distribution systems in modern high-rise buildings, factories, and commercial centers. The conductor bars of busbar trunking are typically made of high-quality copper or aluminum, with special surface treatments to ensure excellent conductivity and corrosion resistance. The insulation materials are selected for their high insulation strength, high temperature resistance, and aging resistance, such as polyester film and polycarbonate, ensuring the safety and reliability of the busbar trunking during long-term operation.

[0003] Busbar trunking is generally designed to be relatively short, and it usually needs to be assembled (combined installation) to obtain a suitable length before use. This is because longer busbar trunking is bulky and heavy, posing significant difficulties for transportation and handling. Limited space in transport vehicles, as well as road height and width restrictions, also constrain the length of busbar trunking that can be transported. Furthermore, excessively long busbar trunking is difficult to handle during transport due to its weight and size, making it prone to damage. Secondly, when busbar trunking malfunctions or reaches the end of its service life and needs replacement, shorter busbar trunking allows for easier partial disassembly, repair, or replacement, reducing maintenance costs and time, and minimizing the impact on the entire power supply system. Traditional busbar trunking assembly requires aligning and inserting the busbar trunking connectors with the corresponding copper busbars of the two busbar trunkings, followed by fixing. Additionally, the upper and lower cover plates of the busbar trunking connectors need to be installed, making the operation cumbersome and severely impacting the assembly efficiency of the busbar trunking, resulting in poor performance.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a combined busbar trunking and its assembly method. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a combined busbar trunking and its assembly method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a combined busbar trunking, comprising a busbar trunking body and copper busbars located on both sides of the busbar trunking body, wherein a mounting component is detachably connected to one side of the busbar trunking body, and a connecting block is provided at the side end of the mounting component; the combined busbar trunking further includes:

[0007] The N-shaped lower cover plate is connected to the side end of the connecting block. After the mounting parts are installed on the main body of the busbar trunking, the N-shaped lower cover plate will close the lower part of the copper busbar on this side of the main body of the busbar trunking.

[0008] The N-shaped upper cover plate is aligned with the N-shaped lower cover plate on the same vertical line and is connected to the movable end of the lifting movable component located at the top of the connecting block. The lower part of the N-shaped upper cover plate is fixed to the two side plates of the busbar connector by an insulating rod.

[0009] The fixing component secures the N-shaped lower cover plate and the N-shaped upper cover plate when they are in contact with each other. At this time, the N-shaped lower cover plate and the N-shaped upper cover plate completely close the connection part of the busbar connector.

[0010] The concave-convex structure includes a through groove formed on the top of the N-shaped cover plate, and a limiting block corresponding to the through groove is provided on the other side of the top of the busbar trunking body.

[0011] Preferably, the N-shaped lower cover plate is fixed to the side end of the connecting block via a connecting rod. The lifting and lowering movable component includes a slide rod fixed to the top of the connecting block. A sliding sleeve is slidably connected to the outer wall of the slide rod. The side end of the sliding sleeve is fixed to the N-shaped upper cover plate via the connecting rod. When the N-shaped upper cover plate moves downward, it will drive the sliding sleeve to move up and down. The sliding sleeve slides vertically up and down along the slide rod.

[0012] Preferably, the fixing assembly includes a connecting plate A welded to the front and rear ends of the N-shaped lower cover plate, and a connecting plate B welded to the front and rear ends of the N-shaped upper cover plate. The top of the connecting plate A is welded with a plurality of screws A that are threaded to the nuts on the outer side wall. The connecting plate B has a through hole A on the flush part with the screws A for them to pass through.

[0013] Preferably, the fixing assembly includes a connecting plate C fixed at both ends of the N-shaped lower cover plate and a connecting plate D fixed at both ends of the N-shaped upper cover plate. The bottom of the connecting plate D is provided with a limiting groove A for the insertion of the stop block. The bottom end of the limiting groove A extends upward to form a circular groove. An elastic telescopic rod is installed inside the circular groove. The stop block is rotatably connected to the head of the elastic telescopic rod. The inside of the connecting plate C is provided with a through groove for the stop block to pass through. The bottom of the connecting plate C is also provided with limiting grooves B on both sides of the through groove to limit the stop block after it rotates 90 degrees.

[0014] Preferably, the top of the stop is fixedly connected to a handle that facilitates pulling it upwards. The elastic telescopic rod includes a housing a fixed to the inner surface of the circular groove. An inner block b is slidably connected inside the housing a. The bottom end of the inner block b is connected to the stop via a vertical rod c. A spring Ad is installed between the top of the inner block b and the inner surface of the housing a.

[0015] Preferably, the mounting component is a frame shape that can be fitted onto the main body of the busbar trunking. The upper and lower ends of the main body of the busbar trunking are fixedly connected to mounting plates, and the surface of the mounting plates is fixedly connected to multiple screws on the outer side wall that are threaded to nuts. The mounting component has through holes for the screws to pass through on the flush part with the screws. The mounting component is directly fitted onto the main body of the busbar trunking for positioning, which makes the installation operation more convenient.

[0016] Preferably, both the N-shaped lower cover plate and the N-shaped upper cover plate are provided with heat dissipation holes, and a dust filter is fixedly connected to the inner wall of the heat dissipation holes to prevent dust from entering.

[0017] Preferably, a temperature sensor is installed inside the main body of the busbar trunking. When the temperature sensor detects an abnormal temperature, it will light up an indicator light to trigger an alarm. The bottom of the main body of the busbar trunking is open and can be sealed by a movable sealing plate. When the temperature is too high, the bottom opening of the main body of the busbar trunking can be opened again through the sealing plate to dissipate heat. At the same time, with the opening located at the bottom, the dust inside can also fall off due to gravity during the heat dissipation process.

[0018] Preferably, guide rails for sliding sliders are fixedly connected to both sides of the bottom end of the busbar trunking body. The side end of the slider is fixed to the sealing plate through a connecting rod. A support plate is welded to the front end of the sealing plate. A protrusion is fixedly connected to the surface of the support plate. The front end of the busbar trunking body is fixed to the groove seat through a connecting rod. The protrusion is hollow inside. A vertical plate is set in the middle part to divide the inside of the protrusion into two symmetrical spaces. Both sides of the vertical plate are fixed to the fixing block through springs. Through slots for the fixing block to pass through are also opened on both sides of the groove seat.

[0019] The assembly method of the above-mentioned combined busbar trunking includes the following steps:

[0020] Step 1: Place the mounting piece onto the main body of the busbar trunking, ensuring it is flush against the mounting plate. Simultaneously, the screw B on the mounting plate will pass through the through hole B on the mounting piece. Then, rotate the nut clockwise to install it into the screw B. The nut will slowly press against the surface of the mounting piece, thus completing the installation of the mounting piece.

[0021] Step 2: Place the opposite end of another identical busbar trunking body on the N-shaped lower cover plate, and at the same time align the limiting block on the other busbar trunking body with the through slot at the top of the N-shaped upper cover plate.

[0022] Step 3: Push the N-shaped upper cover plate downwards. The N-shaped upper cover plate drives the sliding sleeve downwards. The sliding sleeve moves straight down along the sliding rod to fit the N-shaped lower cover plate and the N-shaped upper cover plate together. During this process, the through slot A will be inserted into the limit block, and the busbar connector will also be inserted into the copper busbar on the two busbar bodies.

[0023] Step 4: Finally, secure the two N-shaped lower cover plates and the N-shaped upper cover plate together using the fixing components.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In another embodiment of the present invention, the bottom end of the busbar trunking body is closely attached to the N-shaped lower cover plate, and the top end is limited by a concave-convex structure, which can realize the fixation between the two busbar trunking bodies and the fixation between the busbar trunking connector and the copper busbars on the two busbar trunking bodies. It is not necessary to fix the busbar trunking connector and the copper busbars on the busbar trunking body separately. At the same time, during installation, the insertion position of the busbar trunking connector can be quickly found without the need for alignment operation between the busbar trunking connector and the copper busbars on the two busbar trunking bodies. Moreover, the two side plates on the busbar trunking body are fixed to the N-shaped upper cover plate by insulating rods. After the N-shaped upper cover plate and the N-shaped lower cover plate fix the position of the two busbar trunking bodies, the position of the busbar trunking connector is also fixed at the same time, without the need for further fixing operation. It is only necessary to fix the N-shaped upper cover plate to the N-shaped lower cover plate, without the need to fix the two cover plates separately. Compared with the prior art, it is more convenient to operate, so as to solve the problem that the operation is more cumbersome in the prior art, which seriously affects the combination efficiency of the busbar trunking and the poor use effect.

[0026] 2. In this invention, when the N-shaped lower cover plate and the N-shaped upper cover plate are fitted together and the connection part of the busbar connector is completely closed, heat dissipation is achieved through heat dissipation holes, and the dust filter can prevent dust from entering.

[0027] 3. When the temperature sensor detects an abnormal temperature, the present invention will issue an alarm by illuminating an indicator light. The opening can be opened to dissipate heat by moving the sealing plate.

[0028] 4. The second embodiment of the fixing component of the present invention does not have the problem of missing nuts, and does not require the use of tools, making it more convenient for workers to operate. Attached Figure Description

[0049] Example 1

[0050] like Figure 1 , Figure 3 as well as Figure 5 As shown, the present invention provides a combined busbar trunking, including a busbar trunking body 1 and copper busbars 2 located on both sides of the busbar trunking body 1. A mounting component 3 is detachably connected to one side of the busbar trunking body 1, and a connecting block 4 is provided at the side end of the mounting component 3. The combined busbar trunking also includes:

[0051] The N-shaped lower cover plate 5 is connected to the side end of the connecting block 4. After the mounting part 3 is installed on the busbar trunking body 1, the N-shaped lower cover plate 5 closes the lower part of the copper busbar 2 on this side of the busbar trunking body 1. The N-shaped lower cover plate 5 is fixed to the side end of the connecting block 4 through the connecting rod A12.

[0052] The N-shaped upper cover plate 6 is aligned with the N-shaped lower cover plate 5 on the same vertical line and is connected to the movable end of the lifting and moving assembly 7 located on the top of the connecting block 4. The N-shaped upper cover plate 6 is fixed to the two side plates of the busbar connector 9 by an insulating rod 8. The lifting and moving assembly 7 includes a slide rod 701 fixed to the top of the connecting block 4. A sliding sleeve 702 is slidably connected to the outer wall of the slide rod 701. The side end of the sliding sleeve 702 is fixed to the N-shaped upper cover plate 6 by a connecting rod B13.

[0053] The fixing component 10 fixes the N-shaped lower cover plate 5 and the N-shaped upper cover plate 6 when they are in contact with each other. At this time, the N-shaped lower cover plate and the N-shaped upper cover plate 6 completely close the connection part of the busbar connector 9.

[0054] The concave-convex structure 11 includes a through groove A1101 opened on the top of the N-shaped upper cover plate 6, and a limiting block 1102 corresponding to the through groove A1101 is provided on the other side of the top of the busbar trunking body 1.

[0055] Before leaving the factory, the mounting component 3 is installed on the busbar trunking body 1 (this is because most busbar trunking bodies 1 need to be used in combination, and the busbar trunking bodies 1 that do not need to be combined are disassembled, which helps to save manpower; the busbar trunking connector 9, N-shaped lower cover plate 5, N-shaped upper cover plate 6, fixing component 10 and other components are set on the mounting component 3). Then, the opposite end of another identical busbar trunking body 1 is placed on the N-shaped lower cover plate 5. At the same time, the limiting block 1102 on the other busbar trunking body 1 is aligned with the through groove A1101 at the top of the N-shaped upper cover plate 6 (a small protrusion 32 can be provided on the N-shaped lower cover plate 5 to quickly find the alignment point of the limiting block 1102 and the through groove A1101 when the other busbar trunking body 1 is placed on the N-shaped upper cover plate 6). At this time, the appropriate distance left between the two busbar trunking bodies 1 can be used to install the busbar trunking connector 9. Then, the N-shaped upper cover plate 6 is pushed downward. The sliding sleeve 702 moves downwards, and moves linearly downwards along the sliding rod 701 to bring the N-shaped lower cover plate 5 and the N-shaped upper cover plate 6 into contact. Simultaneously, the busbar connector 9 is inserted into the copper busbars 2 on the two busbar bodies 1. (It should be noted that the standardized, high-precision manufactured busbar connector 9 has fixed positions on its copper busbars. It only needs to be aligned with the copper busbars 2 on the busbar body 1 before direct insertion and assembly, without needing to adjust the distance between the copper busbars on the busbar connector 9. If the copper busbars on the busbar connector 9 could be moved and adjusted, it would not be compatible with this invention.) After insertion, the electrical connection between the two busbars is achieved. At this time, N... The N-shaped lower cover plate and the N-shaped upper cover plate 6 completely close the connection part of the busbar connector 9. After the two N-shaped lower cover plates 5 and the N-shaped upper cover plate 6 are fixed together by the fixing component 10, they can effectively prevent dust and dirt. At the same time, when the N-shaped upper cover plate 6 moves downward, the through groove A1101 on it will be inserted into the limiting block 1102. In this way, the bottom end of the other busbar body 1 is close to the N-shaped lower cover plate 5, and the top end is limited by the concave and convex structure 11, thus fixing the two busbar bodies 1 together. At the same time, the busbar connector 9 is fixed to the copper busbars 2 on the two busbar bodies 1. No additional fixing of the busbar connector 9 is required. The busbars 2 on the busbar trunking body 1 are fixed together. During installation, the insertion position of the busbar trunking connector 9 can be quickly located (simply place the opposite end of the other busbar trunking body 1 on the N-shaped lower cover plate 5, aligning the limiting block 1102 on that end with the through slot A1101 on the N-shaped upper cover plate 6 of the previous busbar trunking body 1; at this point, the copper busbars 2 on the two busbar trunking bodies 1 reach the insertion position of the busbar trunking connector 9). No alignment operation between the busbar trunking connector 9 and the copper busbars 2 on the two busbar trunking bodies 1 is required. Furthermore, the two side plates on the busbar trunking body 1 are fixed to the N-shaped upper cover plate 6 via insulating rods 8.Once the N-shaped upper cover plate 6 and the N-shaped lower cover plate 5 fix the positions of the two busbar trunking bodies 1, the positions of the busbar trunking connector 9 are also fixed simultaneously, eliminating the need for further fixing operations. Furthermore, the upper cover plate 6 is simply fixed to the lower cover plate 5; fixing both covers is unnecessary, making the operation more convenient compared to existing technologies.

[0056] Furthermore, both the N-shaped lower cover plate 5 and the N-shaped upper cover plate 6 are provided with heat dissipation holes 16. A dust filter 17 is fixedly connected to the inner wall of the heat dissipation hole 16. When the N-shaped lower cover plate 5 and the N-shaped upper cover plate 6 are in close contact with each other and the connection part of the busbar connector 9 is completely closed, heat dissipation is achieved through the heat dissipation hole 16, and the dust filter 17 can prevent dust from entering.

[0057] It should be noted that after the busbar connector 9 is installed, there is still a certain distance between it and the N-shaped lower cover plate 5. It is connected to the N-shaped upper cover plate 6 by the insulating rod 8, so there will be no safety issues.

[0058] Example 2:

[0059] like Figure 3 , Figure 4 , Figure 6 , Figure 7 as well as Figure 8 As shown, this embodiment is an improvement on embodiment 1. A temperature sensor is installed inside the main body 1 of the busbar trunking. When the temperature sensor detects an abnormal temperature, it will illuminate indicator light 18 to trigger an alarm. (The temperature sensor continuously monitors and collects data on the temperature of the surrounding environment or the monitored object. Then, the temperature sensor compares the collected temperature data with a preset normal temperature range. If the detected temperature value exceeds the normal range, the sensor will send an electrical signal to the control circuit. After receiving this abnormal signal, the control circuit will trigger the power supply circuit of indicator light 18, causing current to flow to indicator light 18. Finally, indicator light 18 is illuminated by the current to alert relevant personnel that the temperature is abnormal.) The bottom of the main body 1 of the busbar trunking is open and sealed by a fixed sealing plate 19. When the temperature is abnormal, the opening can be opened for heat dissipation by moving the sealing plate 19. The specific structure for moving and fixing the sealing plate 19 is as follows:

[0060] The bottom of the busbar trunking body 1 is fixedly connected to guide rails 22 for sliding slider 21. The side of slider 21 is fixed to sealing plate 19 by connecting rod C23. Support plate 24 is welded to the front end of sealing plate 19. Protrusion 25 is fixedly connected to the surface of support plate 24. The front end of busbar trunking body 1 is fixed to groove seat 27 by connecting rod D26. The inside of protrusion 25 is hollow. A vertical plate 28 is set in the middle part to divide the inside of protrusion 25 into two symmetrical spaces. Both sides of vertical plate 28 are fixed to fixing block 30 by spring B29. Through slots B31 for fixing block 30 to pass through are also opened on both sides of groove seat 27.

[0061] The sealing plate 19 is pushed to move back and forth along the main body 1 of the busbar trunking. The sealing plate 19 drives the slider 21 to move back and forth via the connecting rod C23. The slider 21 slides back and forth along the guide rail 22, thereby maintaining the linear movement of the sealing plate 19. When the protrusion 25 on the sealing plate 19 is inserted into the groove seat 27 on the main body 1 of the busbar trunking, the fixing blocks 30 on both sides are first pushed to move towards the middle, thereby pushing the fixing blocks 30 into the interior of the groove seat 27. During this process, the fixing blocks 30 will move along the inside of the protrusion 25 (it should be noted that the cross-section of the fixing block 30 and the cross-section of the protrusion 25 are almost the same, and the fixing block 30 can move stably in a straight line along the protrusion 25). At the same time, the spring B29 is squeezed, thus inserting the protrusion 25. Insert the fixing block 30 into the groove seat 27 (to avoid the fixing block 30 obstructing the insertion of the protrusion 25). After insertion, the fixing block 30 will be flush with the through groove B31. At this time, the spring B29 will be freed from obstruction and begin to extend in the opposite direction, thereby driving the fixing blocks 30 on both sides to move to both sides and pass through the through groove B31 on the groove seat 27, thereby fixing the protrusion 25 and the groove seat 27, and fixing the position of the sealing plate 19. At this time, the sealing plate 19 will seal the notch at the bottom of the busbar trunking body 1. Conversely, push the fixing blocks 30 on both sides to move to the middle and insert them into the protrusion 25, so that the protrusion 25 can be pulled out from the groove seat 27. Then, push the sealing plate 19 to open the opening at the bottom of the busbar trunking body 1.

[0062] Example 3

[0063] like Figure 1 , Figure 3 as well as Figure 5As shown, this embodiment provides a fixing component 10 from Embodiment 1: The fixing assembly 10 includes a connecting plate A1001 welded to the front and rear ends of the N-shaped lower cover plate 5, and a connecting plate B1002 welded to the front and rear ends of the N-shaped upper cover plate 6. The top of the connecting plate A1001 is welded with multiple screws A1003 that are threaded to the nuts on the outer side wall. The connecting plate B1002 has a through hole A1004 on the flush part with the screws A1003 for them to pass through. That is, when the N-shaped upper cover plate 6 is pressed against the N-shaped lower cover plate 5, the screws A1003 on the connecting plate A1001 also pass through the through hole A1004 on the connecting plate B1002. After passing through, the nut is rotated clockwise to install the nut on the screw A1003. The nut moves downward along the screw A1003 and slowly abuts against the top of the connecting plate B1002, thus fixing the N-shaped lower cover plate 5 and the N-shaped upper cover plate 6. Conversely, the fixing between the two can be released by removing the nut on the screw A1003.

[0064] Example 4

[0065] like Figures 9 to 13 As shown, this embodiment provides another fixing component 10 as in Embodiment 1. The fixing component 10 includes a connecting plate C1005 fixed to the front and rear ends of the N-shaped lower cover plate 5, and a connecting plate D1006 fixed to the front and rear ends of the N-shaped upper cover plate 6. The bottom of the connecting plate D1006 has a limiting groove A1008 for inserting the stop block 1007. The bottom end of the limiting groove A1008 extends upward to form a circular groove 1009. An elastic telescopic rod 1010 is installed inside the circular groove 1009. The stop block 1007 is rotatably connected to the head of the elastic telescopic rod 1010 (rotatable connection is achieved through a bearing). The inside of the connecting plate C1005 has a passage for the stop block 1007 to pass through. The bottom of the connecting plate C1005, located on both sides of the through groove 1011, is provided with limiting grooves B1012 to limit the stop 1007 after it rotates 90 degrees. The top of the stop 1007 is fixedly connected to a handle 1013 for easy upward pulling. The elastic telescopic rod 1010 includes a housing 1010a fixed to the inner surface of the circular groove 1009. An inner block 1010b is slidably connected inside the housing 1010a. The bottom end of the inner block 1010b is connected to the stop 1007 via a vertical rod 1010c (rotatable connection). A spring A1010d is installed between the top of the inner block 1010b and the inner surface of the housing 1010a.

[0066] Initially, the stop block 1007 is positioned within the limiting groove A1008. After the N-shaped upper cover plate 6 is aligned downwards with the N-shaped lower cover plate 5, the handle 1013 on the stop block 1007 is passed through the through groove 1011 on the connecting plate C1005, causing the stop block 1007 to reach below the connecting plate C1005. Then, by pulling the handle 1013 downwards, the stop block 1007 is pulled out of the limiting groove A1008 on the connecting plate C1005. Then, it is passed through the through slot 1011 on the connecting plate C1005. During this process, the stop block 1007 will pull the inner block 1010b downward via the vertical rod 1010c. The inner block 1010b moves in a straight line along the inside of the outer shell 1010a (it should be noted that the cross-section of the inner block 1010b is almost the same as the cross-section of the inside of the outer shell 1010a). At the same time, the spring A1010d is stretched. Then, the stop block 1007 is rotated by the handle 1013. The stop block 1007 moves along the vertical rod 1010c. When the head of 10c rotates 90 degrees, the two protruding ends of the stop block 1007 are flush with the limiting groove B1012. At this point, releasing the handle 1013 causes the spring A1010d to contract due to its elasticity, thus moving the stop block 1007 upwards. This inserts the stop block 1007 into the limiting groove B1012 for positioning, thereby fixing the connecting plate C1005 and the connecting plate D1006 together, and also fixing the N-shaped upper cover plate 6 and the N-shaped lower cover plate 5 together. Similarly, ... Pull the stop 1007 out of the limiting groove B1012 (the limiting groove B1012 does not penetrate the connecting plate C1005) through the handle 1013, rotate it to its original angle so that it can pass smoothly through the through groove 1011 and enter the limiting groove A1008, thereby releasing the fixation between the N-shaped upper cover plate 6 and the N-shaped lower cover plate 5. Compared with embodiment 4, there is no problem of missing nuts, and no tools are needed (such as an open wrench is needed to install nuts), which is more convenient for workers to operate.

[0067] Example 5

[0068] like Figure 1 and Figure 2 As shown in the figure, this embodiment provides a specific structure for the installation of the mounting component 3 and the busbar trunking body 1: the mounting component 3 is a frame shape that can be fitted onto the busbar trunking body 1. The upper and lower ends of the busbar trunking body 1 are fixedly connected to the mounting plate 20, and the surface of the mounting plate 20 is fixedly connected to a plurality of screws B14 that are threaded to nuts on the outer side wall. The mounting component 3 and the screws B14 are flush with each other and a through hole B15 is provided for the screws B14 to pass through.

[0069] The mounting component 3 is placed on the busbar trunking body 1, so that it is tightly fitted against the mounting plate 20 on the busbar trunking body 1. At the same time, the screw B14 on the mounting plate 20 also passes through the through hole B15 on the mounting component 3. Then, the nut is rotated clockwise to install the nut in the screw B14. The nut slowly presses against the surface of the mounting component 3, and the installation of the mounting component 3 is finally completed. Conversely, the nut on the screw B14 is removed, and the mounting component 3 is pulled off the busbar trunking body 1 to remove the mounting component 3. The operation is very simple. This makes the installation and removal of components such as the busbar trunking connector 9, the N-shaped lower cover plate 5, the N-shaped upper cover plate 6, and the fixing component 10 very simple, and also avoids the workers wasting time in this area.

[0070] The present invention also provides a method for assembling the above-mentioned combined busbar trunking:

[0071] Step 1: Place the mounting part 3 onto the busbar trunking body 1, so that it is tightly attached to the mounting plate 20 on the busbar trunking body 1. At the same time, the screw B14 on the mounting plate 20 also passes through the through hole B15 on the mounting part 3. Then, turn the nut clockwise to install the nut in the screw B14. The nut slowly presses against the surface of the mounting part 3, and finally the installation of the mounting part 3 is completed.

[0072] Step 2: Place the opposite end of another identical busbar trunking body 1 on the N-shaped lower cover plate 5, and at the same time align the limiting block 1102 on the other busbar trunking body 1 with the through groove at the top of the N-shaped upper cover plate 6.

[0073] Step 3: Push the N-shaped upper cover plate 6 downward. The N-shaped upper cover plate 6 drives the sliding sleeve 702 downward. The sliding sleeve 702 moves downward in a straight line along the sliding rod 701 to fit the N-shaped lower cover plate 5 and the N-shaped upper cover plate 6 together. During this process, the through slot A1101 will be inserted into the limiting block 1102, and the busbar connector 9 will also be inserted into the copper busbar 2 on the two busbar bodies 1.

[0074] Step 4: Finally, fix the two N-shaped lower cover plates 5 and the N-shaped upper cover plate 6 together using the fixing component 10.

[0075] The present invention provides a combined busbar trunking system and its assembly method, which has the following advantages:

[0076] The bottom of the other busbar trunking body 1 is tightly attached to the N-shaped lower cover plate 5, and the top is limited by the concave-convex structure 11, thus fixing the two busbar trunking bodies 1 together. This also completes the fixing of the busbar trunking connector 9 to the copper busbars 2 on the two busbar trunking bodies 1, eliminating the need for additional fixing of the busbar trunking connector 9 to the copper busbars 2 on the busbar trunking body 1. Furthermore, during installation, the insertion point of the busbar trunking connector 9 can be quickly located, eliminating the need for alignment operations between the busbar trunking connector 9 and the copper busbars 2 on the two busbar trunking bodies 1. Moreover, the busbar trunking body 1... The two side plates are fixed to the N-shaped upper cover plate 6 by the insulating rod 8. After the N-shaped upper cover plate 6 and the N-shaped lower cover plate 5 fix the positions of the two busbar trunking bodies 1, the positions of the busbar trunking connector 9 are also fixed at the same time. No further fixing operation is required. Moreover, it is only necessary to fix the N-shaped upper cover plate 6 to the N-shaped lower cover plate 5. There is no need to fix the two cover plates. Compared with the existing technology, it is more convenient to operate, so as to solve the problem that the operation is more cumbersome in the background technology, which seriously affects the combination efficiency of the busbar trunking and the poor use effect.

[0077] When the N-shaped lower cover plate 5 and the N-shaped upper cover plate 6 are fitted together and the connection part of the busbar connector 9 is completely closed, heat is dissipated through the heat dissipation hole 16, and the dust filter 17 can prevent dust from entering.

[0078] When the temperature sensor detects an abnormal temperature, it will light up indicator light 18 to trigger an alarm. The opening can be opened to dissipate heat by moving the sealing plate 19.

[0079] The second embodiment of the fixing component 10 eliminates the problem of lost nuts and does not require tools, making it easier for workers to operate.

[0080] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Those skilled in the art can readily implement the present invention based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the present invention, utilizing the disclosed technical content, are equivalent embodiments of the present invention. Furthermore, any modifications, alterations, or variations made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the present invention.
