Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A split bus duct comprises a bus duct housing 1, a cover plate 2 is installed on the top of the bus duct housing 1, a fixing block 3 is fixedly connected to both left and right sides of the front and rear ends of the bus duct housing 1, a fixing assembly 4 is fixedly connected to the end of the fixing block 3 away from the cover plate 2, and the fixing assembly 4 is used for fast fixing of the cover plate 2, a bottom insulating plate 5 is fixedly connected to the bottom end of the inner side of the bus duct housing 1, a top insulating plate 6 is installed below the cover plate 2, a bus conductor 7 is installed between the bottom insulating plate 5 and the top insulating plate 6, and a bus conductor 7 is fixedly connected between the top insulating plate 6 and the cover plate 2. There are multiple groups of first springs 8 connected to each other, and side adjustment plates 9 are installed on the left and right sides of the bottom insulation plate 5 and the top insulation plate 6. When the bus duct housing 1 is in use, the bottom insulation plate 5 and the top insulation plate 6 are used to clamp and fix the bus conductor 7, and the first spring 8 is used to continuously apply pressure to the top insulation plate 6 to avoid gaps and reduce thermal conductivity. When disassembling the bus duct, it is only necessary to first use the fixing component 4 to release the fixation of the cover plate 2, and then the cover plate 2 can be disassembled, thereby improving the convenience of disassembly and assembly of the bus duct.

[0026] First, the front and rear ends of the bus duct housing 1 are fixedly connected with connecting plates 101, and connecting holes 102 are opened inside the connecting plates 101. The left and right sides of the bus duct housing 1 are fixedly connected with multiple groups of heat sinks 103. The connecting plates 101 and the connecting holes 102 inside them are used to facilitate the connection and assembly between the bus duct housings 1. At the same time, when the bus duct housing 1 is in use, the multiple groups of heat sinks 103 on the outside are used to increase the heat dissipation area of ​​the bus duct housing 1, thereby improving the heat dissipation effect of the bus duct housing 1.

[0027] Furthermore, a fixing hole 201 is provided at the connection between the outer side of the cover plate 2 and the fixing component 4, and a fixing groove 202 is formed between the cover plate 2 and the fixing component 4. The front and rear ends of the cover plate 2 are movably plugged into the inner side of the fixing groove 202. When the cover plate 2 is installed, its front end is movably plugged into the inner side of the fixing groove 202, and then it can be fixed using the fixing component 4, which facilitates quick disassembly and assembly.

[0028] Then, the fixing assembly 4 includes a fixing box 401, a slider 402, a second spring 403, an insert block 404 and a transmission rod 405. The fixing box 401 is fixedly connected to the end of the fixing block 3 away from the cover plate 2, the slider 402 is slidably connected to the inside of the fixing box 401, the second spring 403 is fixedly connected to the bottom of the slider 402, the insert block 404 is slidably connected to the end of the fixing box 401 close to the cover plate 2, and the transmission rod 405 is installed between the slider 402 and the insert block 404. After pressing the slider 402 downward, the transmission rod 405 drives the pull of the insert block 404, so that the insert block 404 is moved out from the inner side of the fixing hole 201, and the fixation of the cover plate 2 can be released, thereby facilitating and quickly disassembling and assembling the cover plate 2.

[0029] Furthermore, a button 406 is fixedly connected to the top of the slider 402, and the left and right ends of the slider 402 are slidably connected to the fixed box 401 through a sliding rod 407, and the upper and lower ends of the plug block 404 are slidably connected to the fixed box 401 through a sliding groove 408. The left and right ends of the transmission rod 405 are rotatably connected to the slider 402 and the plug block 404 respectively. The slider 402 is pressed down by pressing the button 406, and the plug block 404 is driven by the transmission rod 405 to slide in the sliding groove 408, so that the plug block 404 is moved out from the inner side of the fixing hole 201, and the fixation of the cover plate 2 can be released, thereby facilitating and quickly disassembling and assembling the cover plate 2.

[0030] Secondly, positioning grooves 501 are provided on the inner sides of the bottom insulating plate 5 and the top insulating plate 6, and the upper and lower ends of the bus conductor 7 are located on the inner sides of the positioning grooves 501. The inner sides of the positioning grooves 501 are fixedly connected with rubber pads 502. The positioning grooves 501 are used to position the upper and lower ends of the bus conductor 7. At the same time, the rubber pads 502 are used to prevent the top insulating plate 6 from being over-pressed and causing pinching of the bus conductor 7. While increasing friction and improving the fixing effect of the bus conductor 7, the protection of the bus conductor 7 is improved.

[0031] Finally, the side adjustment plate 9 is composed of a fixed plate 901 and a telescopic plate 902. The telescopic plate 902 is slidably connected to the fixed plate 901. The fixed plate 901 is fixedly connected to the left and right sides of the bottom insulating plate 5. The telescopic plate 902 is fixedly connected to the left and right sides of the top insulating plate 6. The outer side of the fixed plate 901 is fixedly connected with multiple groups of heat dissipation strips 903. When the top insulating plate 6 and the bottom insulating plate 5 fix the bus conductor 7, the telescopic plate 902 is inserted into the inner side of the fixed plate 901 to ensure the stability between the top insulating plate 6 and the bottom insulating plate 5. At the same time, the multiple groups of heat dissipation strips 903 are used to increase the heat dissipation area of ​​the outer side of the fixed plate 901, thereby further improving the heat dissipation effect of the bus duct.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the bus duct housing 1 is in use, the bus conductor 7 is clamped and fixed by the bottom insulating plate 5 and the top insulating plate 6, and the upper and lower ends of the bus conductor 7 are positioned by the positioning groove 501. At the same time, the rubber pad 502 is used to prevent the top insulating plate 6 from being excessively pressed down to cause damage to the bus conductor 7. While increasing friction to improve the fixing effect of the bus conductor 7, the protection of the bus conductor 7 is improved. At the same time, the first spring 8 is used to continuously apply pressure to the top insulating plate 6 to avoid gaps and reduce thermal conductivity. When disassembling and assembling the bus duct, it is only necessary to press the slide button 406 first. The block 402 is pressed down, and the plug block 404 is driven to slide in the slide groove 408 under the transmission of the transmission rod 405, so that the plug block 404 is moved out from the inner side of the fixing hole 201, and the fixation of the cover plate 2 can be released, so that the cover plate 2 can be quickly disassembled and assembled, and then the cover plate 2 can be disassembled and assembled, thereby improving the convenience of disassembly and assembly of the bus duct. The whole operation process is simple and convenient. Compared with the existing split bus duct, the utility model can improve the fixing effect of the bus conductor 7 through design, avoid the appearance of gaps, reduce the thermal conductivity, and at the same time can quickly disassemble and assemble the cover plate 2, thereby improving the convenience of disassembly and assembly of the split bus duct.
