Description

Technical Field

[0001] This invention relates to the field of busbar technology, specifically a convenient single-unit double-circuit busbar. Background Technology

[0002] A single-unit dual-circuit busbar trunking is an integrated power transmission device. Its core design involves forming two layers of dual power supply circuits within a single metal casing through physical isolation: the upper layer houses the busbars, equipped with copper or aluminum busbar conductors, specifically for transmitting high-current power, with electrical isolation between conductors achieved through insulating phase-separating blocks; the lower layer houses the cables, accommodating multi-core cables, primarily handling low-power circuits such as lighting and low-voltage circuits. Existing busbar trunking systems, especially during vertical installation, require aligning two sets of busbar trunkings before installing the upper side plates and connecting components. This process often requires two or three people simultaneously, consuming significant manpower. Furthermore, while existing single-unit dual-circuit busbar trunking systems can accommodate cables, they are typically installed using fixed frames, resulting in a large size and cumbersome installation. They generally require connecting the busbar trunking first, followed by the cables, which are then installed using insertion methods, a space-constrained and inconvenient installation method. Summary of the Invention

[0003] The purpose of this invention is to provide a convenient single-unit double-circuit busbar trunking to solve the problems mentioned in the background art, such as the need for multiple people to assemble existing busbar trunking and the inconvenience of cable installation.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The feature of this invention is that, through a modular structure, the busbar trunking body can be used normally or can be loaded with cables. Compared with a general busbar trunking, the busbar trunking body itself is only provided with a second support rod. All other components can be disassembled, which increases the flexibility of equipment use and saves the manufacturing cost of the equipment. The set connection bracket has the ability to bundle and fix the cables, as well as the ability to provide auxiliary support and positioning for the busbar trunking body. This can reduce the manpower required for the installation of the busbar trunking body and increase the convenience of equipment use.

[0019] 2. The limiting mechanism set on the connecting bracket of the present invention has the ability to conveniently bundle the cable and squeeze and limit the cable. This ability is easy to use and does not require the cable to be inserted or the use of additional fixing components for limiting during installation. After the overall cable laying is completed, the shielding mechanism can be assembled to complete the installation, making the cable installation more convenient. If the position of the cable needs to be adjusted during the installation process, it is also more convenient. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-11 The present invention provides a technical solution: a convenient single-unit double-circuit busbar trunking, including a busbar trunking body 1 and a connecting bracket 5. Fixed side plates 2 are fixedly installed on both sides of the busbar trunking body 1. Connecting copper plates 3 are provided at the upper and lower ends of the busbar trunking body 1. Two sets of connecting side plates 4 are provided at the connection of the two sets of busbar trunking bodies 1. Two sets of first support rods 6 are fixedly installed at the upper and lower ends of the connecting bracket 5. First support rods 6 are movably provided on the front side of the upper and lower ends of the connecting bracket 5. There are four sets of first support rods 6 in total.

[0034] The locking mechanism 10 includes an insertable square rod 1001 and a square groove 1003. The two sets of first support rods 6 located on the front side of the connecting bracket 5 are fixedly installed with the insertable square rod 1001. The upper and lower sides of the connecting bracket 5 are provided with square grooves 1003, and the insertable square rod 1001 is inserted into the square groove 1003.

[0035] The limiting mechanism 11 includes a placement groove 1101 and a pressing plate 1105. Four sets of placement grooves 1101 are opened on the two sets of first support rods 6 located in front of the connecting bracket 5. A pressing plate 1105 is movably arranged in each placement groove 1101.

[0036] The shielding mechanism 12 includes a shielding plate 1201 and heat sinks 1210. The shielding plate 1201 is provided on the front side of the bus trunking body 1, and the heat sinks 1210 are fixedly mounted on the shielding plate 1201 in an array. This equipment realizes the flexible switching of the cable loading function of the bus trunking body 1 by separating the main body of the bus trunking body 1 from the other components, which increases the flexibility of the equipment during use. The connecting bracket 5 not only has the ability to fix the cables, but also assists in the installation of the bus trunking body 1, which increases the functionality of the equipment during use. In addition, the equipment is also equipped with a shielding mechanism 12 to further fix and shield the cables, while also having the ability to isolate heat dissipation, which increases the stability of the equipment during use.

[0037] Furthermore, two sets of second support rods 8 are fixedly installed on both the front and rear sides of the busbar trunking body 1. The connecting bracket 5 is located on the rear side of the busbar trunking body 1, and the height of the connecting bracket 5 is higher than the height of the connecting side plate 4. This structure is as follows. Figure 2 , Figure 4 and Figure 5 As shown, connectors need to be inserted into the front of the two sets of busbar trunking bodies 1, and connecting side plates 4 need to be installed on the left and right sides. Therefore, the connecting brackets 5 are placed on the rear side and will not obstruct the normal connection and fixation between the busbar trunking bodies 1. Since the connecting brackets 5 are higher than the connecting side plates 4, the connecting brackets 5 can be installed first during installation, so that the busbar trunking body 1 to be installed is supported on the upper side of the busbar trunking body 1 through the connecting brackets 5. This way, the busbar trunking body 1 to be installed does not need to be manually supported when installing connectors or connecting side plates 4. After the busbar trunking body 1 is supported on the connecting brackets 5, the distance between the two sets of connecting copper plates 3 is 40 centimeters, which is in accordance with the requirements. The connection method conforms to the standard connectors, and after the first support rod 6 is assembled, the connecting bracket 5 is installed on the busbar trunking body 1 by inserting it from the top and bottom. With the limiting of the connecting side plate 4, the busbar trunking body 1 will not slip off the connecting bracket 5 due to shaking during the support process, which increases the stability of the equipment during use. The connecting bracket 5 itself has two uses: first, when the busbar trunking body 1 needs to be loaded with cables, the limiting mechanism 11 is used to limit the cables; second, when the cables do not need to be loaded, the connecting bracket 5 can assist the busbar trunking body 1 in positioning. It can be disassembled after installation.

[0038] Furthermore, limit grooves 7 are evenly arranged on the first support rod 6, and limit blocks 9 are evenly arranged and fixedly installed on the second support rod 8. The limit blocks 9 are engaged in the limit grooves 7, and the first support rod 6 does not contact the connecting side plate 4. The central part of the connecting bracket 5 is hollow and a pull rod 13 is fixedly installed thereon. A schematic diagram of this structure is shown below. Figure 4 and Figure 5 The limiting groove 7 and limiting block 9 are set to prevent the busbar trunking body 1 from shifting left and right after the first support rod 6 and the second support rod 8 are engaged, so that the subsequent installation work can be carried out better. The first support rod 6 does not contact the connecting side plate 4, so that the first support rod 6 does not occupy the fixed position of the connecting side plate 4. Due to the presence of the limiting groove 7 and limiting block 9, the busbar trunking body 1 will not be unstable due to the first support rod 6 not contacting the connecting side plate 4. The setting of the pull rod 13 makes it easier to pick up and put down the connecting bracket 5. On the other hand, while taking into account the stability of the connecting bracket 5 itself, it reduces the weight of the connecting bracket 5 itself, thereby reducing the overall weight of the equipment after installation.

[0039] Furthermore, the locking mechanism 10 also includes a limiting hole 1002, a first movable groove 1004, a movable rod 1005, a return spring 1006, a pull plate 1007, a limiting rod 1008, and a first insertion hole 1009. A limiting hole 1002 is provided at the upper end of the insertion rod 1001. Two sets of first movable grooves 1004 are provided at both ends of the connecting bracket 5. A movable rod 1005 is movably inserted into the first movable groove 1004. A return spring 1006 is sleeved on the movable rod 1005. A pull plate 1007 is fixedly installed on both sets of movable rods 1005. A limiting rod 1008 is fixedly installed on the pull plate 1007. A first insertion hole 1009 is provided at both ends of the connecting bracket 5. The position of the first insertion hole 1009 is opposite to the position of the limiting hole 1002. The limiting rod 1008 is inserted into the limiting hole 1002. A schematic diagram of this structure is shown below. Figure 5 and Figure 11 This structure allows for easy disassembly of both sets of first support rods 6 located on the front side of the connecting bracket 5. After the connecting bracket 5 is used as an auxiliary bracket, it can be easily disassembled. When the pull plate 1007 is in its initial position, it is in contact with the connecting bracket 5, and the height of the pull plate 1007 is greater than the width of the upper and lower sides of the connecting bracket 5, so that the pull plate 1007 can be easily pulled out, increasing the convenience of the connecting bracket 5 in use. The limiting rod 1008 is inserted into the first insertion hole 1009 and the limiting hole 1002 to limit the position of the inserted square rod 1001 moving back and forth. The inserted square rod 1001 is inserted into the square groove 1003 to lock the up and down movement of the first support rod 6. Therefore, the structure used to lock the back and forth movement of the first support rod 6 will not be affected by the force on the first support rod 6.

[0040] Furthermore, the limiting mechanism 11 also includes a placement groove 1101, a second movable groove 1102, a first annular rubber pad 1103, a movable plate 1104, and a pressing plate 1105. Placement grooves 1101 are arrayed on the two sets of second support rods 8 on the front side, and the first annular rubber pad 1103 is fixedly installed in each placement groove 1101. Three sets of second movable grooves 1102 are arrayed on the two sets of first support rods 6 on the front side, and movable plates 1104 are movably installed in each second movable groove 1102. Two sets of pressing plates 1105 are rotatably installed on the middle movable plate 1104, and one set of pressing plates 1105 is rotatably installed on the movable plates 1104 on the left and right sides. The width of the pressing plate 1105 is adapted to the width of the first annular rubber pad 1103. A schematic diagram of this structure is shown below. Figure 6 and Figure 10 This structure allows the cable to be placed in the placement slot 1101 and limited by the pressing plate 1105, giving the second support rod 8 and the first support rod 6 the ability to bundle the cable, making it easy to strand the cable during the subsequent cable installation process, thus increasing the functionality of the equipment.

[0041] Furthermore, the limiting mechanism 11 also includes a fixed rod 1106, a rotating groove 1107, a sector-shaped limiting ring 1108, a limiting piece 1109, and a torsion spring 1110. Fixed rods 1106 are fixedly installed on both sides of the central movable plate 1104 and on one side of the two side movable plates 1104. A rotating groove 1107 is opened at one end of each pressing plate 1105. The fixed rod 1106 is rotatably installed within the rotating groove 1107. Sector-shaped limiting rings 1108 are fixedly installed on the upper and lower sides of the rotating groove 1107. Limiting pieces 1109 are fixedly installed on the upper and lower sides of the fixed rod 1106, abutting against the sector-shaped limiting rings 1108. A torsion spring 1110 is located at the center of the fixed rod 1106, with one end fixedly installed on the fixed rod 1106 and the other end fixedly installed within the rotating groove 1107. The length of the pressing plate 1105 is less than the width of the placement groove 1101. A schematic diagram of this structure is shown below. Figure 6 and Figure 7 This structure allows the pressing plate 1105 to rotate only inward, so that the cable can be directly pressed into the placement groove 1101, increasing the convenience of cable installation. Since the width of the pressing plate 1105 is equal to the width of the first annular rubber pad 1103, the pressing plate 1105 will not block the cable from entering the placement groove 1101 and fitting into the first annular rubber pad 1103 after rotation, increasing the smoothness of equipment use.

[0042] Furthermore, the limiting mechanism 11 also includes a first threaded sleeve 1111, a first screw 1112, a knob 1113, a rotating block 1114, a transmission rod 1115, and a third movable groove 1116. A first threaded sleeve 1111 is fixedly installed at the center of each movable plate 1104. A first screw 1112 is rotatably installed in each of the second movable grooves 1102. A knob 1113 is fixedly installed on the middle first screw 1112. A rotating block 1114 is fixedly installed at one end of each of the three sets of first screws 1112. The same set of transmission rods 1115 is rotatably installed on each of the three sets of rotating blocks 1114. A third movable groove 1116 is provided on each of the two sets of first support rods 6 on the front side. The rotating block 1114 and the transmission rod 1115 move within the third movable groove 1116. A schematic diagram of this structure is shown below. Figure 6 This structure allows the position of the movable plate 1104 to be adjusted. When the movable plate 1104 is located behind the second movable groove 1102, the pressing plate 1105 will abut against the cable, thereby squeezing the cable to achieve positioning. At this time, the pressing plate 1105 cannot rotate. When the movable plate 1104 is located in front of the second movable groove 1102, the movable plate 1104 can rotate and after rotation, it will be in close contact with the inner wall of the placement groove 1101, which will not obstruct the removal of the cable. At the same time, by rotating the circular block 1114 and the transmission rod 1115, the three sets of first screws 1112 can rotate synchronously, which increases the convenience of using the equipment.

[0043] Furthermore, the shielding mechanism 12 also includes a sealing side plate 1202, a second insertion hole 1203, a second screw 1204, a second screw sleeve 1205, a pressure block 1206, and a second annular rubber gasket 1207. Sealing side plates 1202 are fixedly installed on both the left and right sides of the shielding plate 1201, and the sealing side plates 1202 and the connecting side plate 4 are fitted together. Two sets of second insertion holes 1203 are provided at both the upper and lower ends of the shielding plate 1201, and a second screw 1204 is movably inserted into each of the second insertion holes 1203. 4. Two sets of second threaded sleeves 1205 are fixedly installed inside the two sets of second support rods 8 on the front side. The second screw 1204 is threadedly installed inside the second threaded sleeve 1205. Pressure blocks 1206 are fixedly installed in an array on the upper and lower sides of the shielding plate 1201. A second annular rubber pad 1207 is fixedly installed on each pressure block 1206. The position of the pressure block 1206 is opposite to the position of the placement groove 1101 opened on the two sets of second support rods 8 on the front side. The pressure block 1206 is inserted into the placement groove 1101. A schematic diagram of this structure is shown below. Figure 3 , Figure 9 and Figure 10The shielding plate 1201 can be fixedly installed on the busbar trunking body 1, and through the cooperation between the pressure block 1206 and the second support rod 8 with the placement slot 1101, the cable is further pressed, so that after the cable is installed, its two ends on a set of busbar trunking bodies 1 can be limited in two different ways, which increases the stability of the cable during installation. The presence of the shielding plate 1201 itself can reduce the corrosion of the cable by dust in the air, which increases the stability of the equipment during use.

[0044] Furthermore, the shielding mechanism 12 also includes a partition plate 1208 and a ventilation filter 1209. The partition plate 1208 is fixedly mounted in an array on the front side of the shielding plate 1201. The partition plate 1208 is positioned between two adjacent sets of pressure blocks 1206. The partition plate 1208 is in contact with the busbar trunking body 1. Ventilation filters 1209 are fixedly mounted in an array on both the upper and lower sides of the shielding plate 1201. The ventilation filters 1209 are positioned between two adjacent sets of partition plates 1208. A schematic diagram of this structure is shown below. Figure 3 and Figure 9 The cables need to be installed on one side of the bus trunking body 1, and a shielding plate 1201 is also needed to protect the cables. Therefore, the side of the bus trunking body 1 where the cables are installed is more prone to heat accumulation than the other side. So a partition plate 1208 is set to divide the distribution space of the cables, so that the heat will not be concentrated and can be discharged in time, increasing the heat dissipation efficiency of the equipment. The ventilation filter 1209 can increase the ventilation on the side of the bus trunking body 1 where the cables are installed while ensuring the shielding effect of the shielding plate 1201 on the cables. And because of the presence of the partition plate 1208, a narrow tube effect is easily formed in the shielding plate 1201, which makes the airflow speed faster and is conducive to the heat dissipation of the cables.

[0045] Furthermore, the shielding mechanism 12 also includes a support baffle 1211 and an oblong hole 1212. The support baffle 1211 is disposed between the two sets of busbar trunking bodies 1. The upper and lower ends of the support baffle 1211 abut against the first support rod 6. Oblong holes 1212 are provided on the sides of the support baffle 1211, and the oblong holes 1212 are opposite to the holes on the connecting side plate 4. A schematic diagram of this structure is shown below. Figure 1 and Figure 8 This structure allows the support baffle 1211 to not only shield the cable located at the connection point of the busbar trunking body 1, but also to support the front side of the connecting bracket 5 by abutting against the first support rod 6, thereby increasing the structural strength of the connecting bracket 5 and increasing the stability of the equipment during use.

[0046] Working principle: When using this invention, one end of the connecting bracket 5 is engaged on the busbar trunking body 1. At this time, the first support rod 6 and the second support rod 8 abut against each other. Then, another set of busbar trunking bodies 1 is placed on the connecting bracket 5. At this time, the two sets of busbar trunking bodies 1 are opposite each other. Then, the two sets of busbar trunking bodies 1 are connected by connectors. After installation, the connecting side plates 4 are closed on both sides and fixed. At this time, the connection between the busbar trunking bodies 1 is completed.

[0047] When there is no need to lay cables, pull the pull plate 1007 to move the movable rod 1005 in the first movable groove 1004 and compress the return spring 1006, thereby causing the limit rod 1008 to be pulled out from the limit hole 1002. The first support rod 6 located on the front side of the busbar trunking body 1 can then be separated. Then, hold the pull rod 13 to pull away the connecting bracket 5 to complete the disassembly of the connecting bracket 5.

[0048] When laying cables, during the assembly of the connecting side plates 4, the support baffles 1211 need to be attached to the two sets of connecting side plates 4 for assembly. At this time, the support baffles 1211 abut against the first support rod 6, pressing the cable into the placement groove 1101. At this time, the pressing plate 1105 rotates inward so that the cable can be loaded into the placement groove 1101. Then, the knob 1113 is rotated to make the first screw 1112 rotate. And through the transmission between the rotating block 1114 and the transmission rod 1115, the other two sets of first screws 1112 are driven to rotate. Through the thread action between the first screw sleeve 1111, the movable plate 1104 is driven to move between the second movable groove 1102, so that the pressing plate 1105 presses the cable to complete the initial fixing of the cable.

[0049] After the cable laying is completed, the shielding plate 1201 is attached to the bus trunking body 1. The assembly of the shielding plate 1201 is completed by screwing the second screw 1204 into the second screw sleeve 1205. At this time, the pressure block 1206 presses the cable to complete the cable fixing. Disassembly is the same.
