Abstract
Description
Technical Field
[0001] This utility model relates to a dense insulated busbar trunking, and more particularly to a dense insulated busbar trunking, belonging to the technical field of insulated busbar trunking. Background Technology
[0002] Busbar trunking is a dense, insulated, enclosed metal device. It mainly consists of a protective shell made up of a cover plate and connecting side plates, conductive bars, insulating materials, and related accessories. According to the insulation method, it can be divided into three types: air-insulated plug-in busbar trunking, dense insulated plug-in busbar trunking, and high-strength plug-in busbar trunking. It is used to distribute a large amount of power to various components in a distributed system. The conductive bars of dense busbar trunking are mostly fixed in the protective shell by fastening bolts to avoid damage to the conductive bars.
[0003] Existing compact busbar trunking has a simple structure. The conductive bars of traditional compact busbar trunking are mostly fixed in the protective shell by fastening bolts. This method requires workers to use auxiliary tools such as screwdrivers and wrenches to operate during installation, which is time-consuming and labor-intensive. Moreover, the installation and disassembly of the conductive bars are very inconvenient during the later maintenance, which reduces the efficiency of maintenance work.
[0004] Therefore, there is an urgent need to improve a dense insulated busbar trunking system to solve the aforementioned problems. Utility Model Content
[0005] The purpose of this invention is to provide a compact insulated busbar trunking system. By using a splicing structure, it changes the traditional method of fixing the conductive busbars within a protective housing using bolts. This eliminates the need for screwdrivers, wrenches, or other tools during installation. First, multiple first and second protective housings are placed over the conductive busbars. Then, multiple protrusions on connecting brackets are aligned with grooves and inserted to connect the first and second protective housings. The concave-convex shape of the protrusions and grooves prevents the connecting brackets from detaching due to lateral pulling. Once the protrusions are fully inserted into the grooves, multiple locking blocks engage with the locking holes under the elastic action of multiple first springs, improving the stability of the connecting bracket connection. Disassembly of the connecting bracket simply requires pulling it to compress the locking blocks into the mounting holes. Once the locking blocks disengage from the locking holes, the connecting bracket can be removed, allowing for the removal of the first and second protective housings. This structure saves time and effort, and facilitates convenient installation and disassembly during subsequent maintenance of the conductive busbars, thus improving maintenance efficiency.
[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:
[0007] A compact insulated busbar trunking includes a conductive busbar. Multiple first and second protective shells are mounted on the outer side of the conductive busbar. A splicing structure is provided on the first protective shell. The splicing structure includes multiple connecting brackets installed at the connection points between the first and second protective shells. Multiple protrusions are fixedly mounted on the connecting brackets. Multiple grooves adapted to the protrusions are formed on both the first and second protective shells. Multiple mounting holes are formed on the protrusions. A first spring is fixedly mounted inside each mounting hole. A locking block is fixedly mounted on one end of the first spring. Multiple locking holes that cooperate with the locking block are formed inside the grooves.
[0008] Preferably, one end of the card block is arc-shaped, and a rubber support that fits against the conductive bar is fixedly installed on the inner wall of the second protective shell.
[0009] Preferably, the first protective shell has a ventilation opening, and a cooling fan is fixedly installed inside the ventilation opening.
[0010] Preferably, the outer side of the cooling fan is provided with a dust cover that is connected to the first protective shell.
[0011] Preferably, a first magnetic ring connected to the first protective shell is fixedly installed on the outer side of the vent, and a second magnetic ring magnetically connected to the first magnetic ring is fixedly installed at one end of the dust cover.
[0012] Preferably, limit plates are provided on both sides of the conductive busbar, and multiple limit rods are fixedly installed on one end of the limit plate. Limiting holes adapted to the limit rods are provided on the connecting frame.
[0013] Preferably, a collision box is provided on one side of the limiting rod, a first fixing plate is fixedly installed on the collision box, a second fixing plate is fixedly installed on both the first protective shell and the second protective shell, an insert rod connected to the second fixing plate is movably installed on the first fixing plate, a latch is fixedly installed at one end of the insert rod, a second spring connected to the first fixing plate is wound on the insert rod, and a connection hole adapted to the latch is provided on both the first fixing plate and the second fixing plate.
[0014] This utility model has at least the following beneficial effects:
[0015] By using a splicing structure, the method of fixing the conductive busbars of the high-density busbar trunking to the protective housing with fastening bolts has been changed. This eliminates the need for workers to use screwdrivers, wrenches, or other tools when installing the protective housing. First, multiple first and second protective housings are placed over the outside of the conductive busbars. Then, multiple protrusions on multiple connecting brackets are aligned with the grooves and inserted to connect the first and second protective housings. The concave-convex shape design of the protrusions and grooves prevents the connecting brackets from falling off due to lateral pulling. When the protrusions are fully inserted into the grooves, multiple locking blocks are engaged in the locking holes under the elastic action of multiple first springs, thereby improving the stability of the connecting bracket connection. When the connecting bracket is disassembled, it is only necessary to pull it to compress the locking blocks into the mounting holes. Once the locking blocks detach from the locking holes, the connecting bracket can be disassembled. After the connecting bracket is disassembled, the first and second protective housings can be disassembled. The advantages of this structure are that it saves time and effort, and the installation and disassembly are very convenient during the later maintenance of the conductive busbars, thereby improving the efficiency of maintenance work.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0027] like Figures 1-8 As shown in the figure, this embodiment provides a compact insulated busbar trunking embodiment.
[0028] A compact insulated busbar trunking includes a conductive busbar 1. Multiple first protective shells 2 and second protective shells 3 are mounted on the outer side of the conductive busbar 1. A splicing structure 4 is provided on the first protective shell 2. The splicing structure 4 includes multiple connecting brackets 5 installed at the connection points of the first protective shell 2 and the second protective shell 3. Multiple protrusions 6 are fixedly installed on the connecting brackets 5. Multiple grooves 7 that mate with the protrusions 6 are provided on both the first protective shell 2 and the second protective shell 3. Multiple mounting holes 8 are provided on the protrusions 6. A first spring 9 is fixedly installed inside the mounting holes 8. A locking block 10 is fixedly installed at one end of the first spring 9. Multiple locking holes 11 that cooperate with the locking block 10 are provided inside the grooves 7. By setting up the splicing structure 4, the method of fixing the conductive busbar of the compact busbar trunking to the protective shell using fastening bolts is changed. This eliminates the need for workers to use screwdrivers, wrenches, or other tools when installing the protective shell. Firstly, multiple first protective shells... The outer shell 2 and the second protective shell 3 cover the outside of the conductive busbar 1. Then, multiple protrusions 6 on multiple connecting brackets 5 are aligned with the grooves 7 and inserted to connect multiple first protective shells 2 and second protective shells 3. The concave-convex shape design of the protrusions 6 and the grooves 7 can prevent the connecting brackets 5 from falling off due to lateral pulling. When the protrusions 6 are fully inserted into the grooves 7, multiple locking blocks 10 can be locked into the locking holes 11 under the elastic action of multiple first springs 9, thereby improving the stability of the connection of the connecting brackets 5. When the connecting brackets 5 are disassembled, they only need to be pulled to compress and shrink the locking blocks 10 into the mounting holes 8. When the locking blocks 10 are disengaged from the locking holes 11, the connecting brackets 5 can be disassembled. After the connecting brackets 5 are disassembled, the first protective shells 2 and the second protective shells 3 can be disassembled. The advantage of this structure is that it saves time and effort, and the installation and disassembly are very convenient during the later maintenance of the conductive busbar, thereby improving the efficiency of maintenance work.
[0029] like Figure 4 and Figure 5 As shown, one end of the locking block 10 is arc-shaped, and a rubber support 12 that fits against the conductive busbar 1 is fixedly installed on the inner wall of the second protective shell 3. By setting one end of the locking block 10 to be arc-shaped and the setting of the rubber support 12, the friction of one end of the locking block 10 can be reduced, making the locking block 10 slide more smoothly inside the groove 7, thereby facilitating the disassembly and installation of the connecting frame 5. The rubber support 12 can squeeze the conductive busbar 1 to fix it, which can improve the stability of the conductive busbar 1 inside the first protective shell 2 and the second protective shell 3, and prevent the conductive busbar 1 from shaking and affecting the conductivity of the conductive busbar 1.
[0030] like Figure 6As shown, the first protective housing 2 has a ventilation opening 13, and a cooling fan 14 is fixedly installed inside the ventilation opening 13. Through the arrangement of the ventilation opening 13 and the cooling fan 14, the heat generated by the conductive busbar 1 can be dissipated through the ventilation opening 13. When the heat is too high, the cooling fan 14 can be activated to speed up the heat dissipation and prevent the excessive heat from damaging the conductive busbar 1.
[0031] like Figure 2 As shown, the outer side of the cooling fan 14 is provided with a dust cover 15 connected to the first protective shell 2. The dust cover 15 can block external dust or debris, preventing dust and debris from entering the interior of the conductive busbar 1 through the ventilation port 13 and affecting it.
[0032] like Figure 6 As shown, a first magnetic ring 16 connected to the first protective shell 2 is fixedly installed on the outside of the vent 13. A second magnetic ring 17 magnetically connected to the first magnetic ring 16 is fixedly installed at one end of the dust cover 15. With the first magnetic ring 16 and the second magnetic ring 17, the two attract each other and can fix the dust cover 15 to the first protective shell 2 to prevent it from falling off. Due to the characteristics of the first magnetic ring 16 and the second magnetic ring 17, the dust cover 15 can be disassembled without tools, which makes it convenient to disassemble and replace the dust cover 15 when it is damaged.
[0033] like Figure 7 As shown, limit plates 18 are provided on both sides of the conductive busbar 1. Multiple limit rods 19 are fixedly installed on one end of the limit plate 18. Limiting holes 20 adapted to the limit rods 19 are provided on the connecting frame 5. By setting the limit plate 18, the limit rods 19 and the limiting holes 20, the multiple limit rods 19 on the limit plate 18 are aligned with the limiting holes 20 and inserted, which can fix the limit plate 18 to the outside of the first protective shell 2 and the second protective shell 3, and can form a sealed environment inside them, thereby preventing dust from entering the interior through the two ends of the first protective shell 2 and the second protective shell 3. The limit plate 18 can also block the protrusion 6, which can improve the stability of the protrusion 6 inside the groove 7.
[0034] like Figure 8As shown, a crash box 21 is provided on one side of the limiting rod 19. A first fixing plate 22 is fixedly installed on the crash box 21. A second fixing plate 23 is fixedly installed on both the first protective shell 2 and the second protective shell 3. A plug rod 24 connected to the second fixing plate 23 is movably installed on the first fixing plate 22. A latch 25 is fixedly installed at one end of the plug rod 24. A second spring 26 connected to the first fixing plate 22 is wound around the plug rod 24. Both the first fixing plate 22 and the second fixing plate 23 have connection holes 27 that are adapted to the latch 25. The crash box 21, the first fixing plate 22, the second fixing plate 23, the plug rod 24, and the latch are connected to the first fixing plate 22. 25. The second spring 26 and the connection hole 27 are designed so that after multiple anti-collision boxes 21 are fitted onto both ends of the conductive busbar 1, the plug rod 24 is inserted into the connection hole 27 until the first fixing plate 22 and the second fixing plate 23 are connected together. Then, the plug rod 24 is pressed and rotated so that the angle of the latch 25 is adjusted to be perpendicular to the angle of the connection hole 27. The plug rod 24 will be tightened under the elastic tension of the second spring 26, so that the anti-collision box 21 is fixed at both ends of the conductive busbar 1 under a certain tension, which can prevent the conductive busbar 1 from being damaged by impact during transportation, which would affect the normal use of the conductive busbar 1.
[0035] In this embodiment, as Figures 1-8 As shown in the figure, the working process of a compact insulated busbar trunking provided in this embodiment is as follows:
[0036] First, multiple first protective shells 2 and second protective shells 3 are placed over the outside of the conductive busbar 1. Then, multiple protrusions 6 on multiple connecting brackets 5 are aligned with grooves 7 and inserted to connect the multiple first protective shells 2 and second protective shells 3. The concave-convex shape design of the protrusions 6 and grooves 7 can prevent the connecting brackets 5 from falling off due to lateral pulling. When the protrusions 6 are fully inserted into the grooves 7, multiple locking blocks 10 can be engaged in the locking holes 11 under the elastic action of multiple first springs 9, thereby improving the stability of the connection of the connecting brackets 5. When disassembling the connecting brackets 5, it is only necessary to pull them to compress and shrink the locking blocks 10 into the mounting holes 8. When the locking blocks 10 are disengaged from the locking holes 11, the connecting brackets 5 can be disassembled. After the connecting brackets 5 are disassembled, the first protective shells 2 and second protective shells 3 can be disassembled. The advantage of this structure is that it saves time and effort, and the installation and disassembly are very convenient during the later maintenance of the conductive busbar, thereby improving the efficiency of maintenance work.
[0037] In summary, in this embodiment, the dense insulated busbar trunking, with one end of the locking block 10 being arc-shaped and the rubber support 12 being configured, reduces the friction at one end of the locking block 10, making it slide more smoothly inside the groove 7. This facilitates the disassembly and installation of the connecting frame 5. The rubber support 12 can compress and fix the conductive busbar 1, improving the stability of the conductive busbar 1 inside the first protective shell 2 and the second protective shell 3, preventing the conductive busbar 1 from shaking and affecting its conductivity. The ventilation opening 13 and the cooling fan 14 can generate heat from the conductive busbar 1. The heat dissipates through the vent 13. When the heat is too high, the cooling fan 14 is activated to accelerate heat dissipation, preventing damage to the conductive busbar 1 from excessive heat. The dust cover 15 blocks external dust or debris, preventing them from entering the conductive busbar 1 through the vent 13 and affecting it. The first magnetic ring 16 and the second magnetic ring 17 attract each other, fixing the dust cover 15 to the first protective shell 2 to prevent it from falling off. Due to the characteristics of the first magnetic ring 16 and the second magnetic ring 17, the dust cover 15 can be removed without tools, facilitating the installation of protective measures. When the dust cover 15 is damaged, it is disassembled and replaced. Through the setting of the limiting plate 18, limiting rods 19, and limiting holes 20, the multiple limiting rods 19 on the limiting plate 18 are aligned with the limiting holes 20 and inserted, thus fixing the limiting plate 18 to the outside of the first protective shell 2 and the second protective shell 3, forming a sealed environment inside, thereby preventing dust from entering the interior through both ends of the first protective shell 2 and the second protective shell 3. The limiting plate 18 can also block the protrusion 6, improving the stability of the protrusion 6 inside the groove 7. This is achieved through the anti-collision box 21, the first fixing plate 22, the second fixing plate 23, the insert rod 24, and the latch 25. The second spring 26 and the connecting hole 27 are designed so that after multiple anti-collision boxes 21 are fitted onto both ends of the conductive busbar 1, the insert rod 24 is inserted into the connecting hole 27 until the first fixing plate 22 and the second fixing plate 23 are connected together. Then, the insert rod 24 is pressed and rotated so that the angle of the latch 25 is adjusted to be perpendicular to the angle of the connecting hole 27. The insert rod 24 will be tightened under the elastic tension of the second spring 26, so that the anti-collision box 21 is fixed at both ends of the conductive busbar 1 under a certain tension. This can prevent the conductive busbar 1 from being damaged by impact during transportation, which would affect the normal use of the conductive busbar 1.
