By connecting the upper cover plate 20 and the bus duct carrier 10 by plugging, and squeezing and clamping the upper cover plate 20 on the bus duct carrier 10 by an elastic clamping mechanism, no bolt connection is required, which is convenient for disassembly and assembly; the support frame 40 with the conductive bar 30 is abutted against the bus duct carrier 10 by the elastic squeezing structure, and can be directly squeezed into or taken out during disassembly and assembly, which is convenient and fast, and no connection structure is required to occupy space and affect power transmission. The bus duct of the present application does not require too many connecting parts for disassembly and assembly, which is convenient, fast and easy to maintain.

[0028] Next, a bus duct in this exemplary embodiment will be further described.

[0029] In the embodiment of the present application, the upper cover plate 20 is covered on the top of the bus duct carrier 10, and connecting plates 21 are respectively provided on both sides of the upper cover plate 20. Connecting grooves 11 are opened on the top of both sides of the bus duct carrier 10, and the connecting plates 21 are inserted into the connecting grooves 11 and abut against the inner wall of the connecting grooves 11; the connection is connected in a plug-in manner, which is convenient and fast to disassemble and assemble. The connecting groove 11 is provided with an extrusion plate 50 that is parallel to the connecting plate 21, and an elastic clamping mechanism is connected to the side of the extrusion plate 50 away from the connecting plate 21, and the elastic clamping mechanism passes through the side wall of the bus duct carrier 10 and extends outward; the elastic clamping mechanism is used to push the extrusion plate 50 to squeeze the connecting plate 21. By controlling the elastic clamping mechanism outside the bus duct carrier 10, the extrusion plate 50 is driven to move, and the connecting plate 21 is tightly squeezed into the connecting groove 11. During disassembly, the elastic clamping mechanism is controlled from the outside to drive the extrusion plate 50 to move outward, thereby loosening the connecting plate 21. At this time, the upper cover plate 20 is moved upward for disassembly.

[0030] As an example, the elastic clamping mechanism includes a rotating shaft 61, a first gear 62 and a transmission assembly, the transmission assembly includes a second gear 63, a rack 64 and a first spring 65, the rotating shaft 61 passes through the side wall of the bus duct carrier 10 and extends into the connecting groove 11, the first gear 62 is sleeved on the end of the rotating shaft 61, the second gear 63 is vertically meshed with the first gear 62 and is located in the connecting groove 11, the rack 64 is meshed with the second gear 63, and one end of the rack 64 is fixedly connected to the extrusion plate 50; the first spring 65 is connected between the other end of the rack 64 and the inner wall of the connecting groove 11. By externally controlling the rotation of the rotating shaft 61, the first gear 62 is driven to rotate, the first gear 62 drives the second gear 63 to rotate, the rotation of the second gear 63 drives the rack 64 to move outward, the rack 64 drives the extrusion plate 50 to move outward, thereby loosening the connecting plate 21. At this time, the upper cover plate 20 can be removed, and the first spring 65 is compressed by the extrusion plate 50; when the rotating shaft 61 is loosened, under the action of the elastic restoring force of the first spring 65, the extrusion plate 50 is driven to move inward to squeeze the connecting plate 21.

[0031] In a specific embodiment, when the upper cover 20 is to be installed, the rotating shaft 61 is rotated so that the extrusion plate 50 moves outward, and the connecting plate 21 can be inserted into the connecting groove 11. After insertion, the rotating shaft 61 is loosened, so that the extrusion plate 50 moves inward under the action of elasticity to squeeze the connecting plate 21 and press it tightly into the connecting groove 11; when the upper cover 20 is to be removed, the rotating shaft 61 is rotated so that the extrusion plate 50 moves outward, and the connecting plate 21 is loosened to remove it.

[0032] As an example, a rotating handle may be provided at one end of the rotating shaft 61 located outside the bus duct carrier 10 for easy operation.

[0033] As an example, see Figure 3 The transmission assembly is provided with two groups, and the two groups of the transmission assembly are symmetrically arranged with the first gear 62 as the center. The rotation direction of the two second gears 63 is the same. By providing two groups of transmission assemblies, the two racks 64 are respectively connected to the upper and lower parts of the connecting plate 21, so that the upper and lower parts have extrusion force at the same time, thereby improving the clamping force of the extrusion plate 50 on the connecting plate 21.

[0034] As an example, the transmission assembly is provided with two groups, and the two groups of the transmission assembly are located on the same horizontal line and are arranged at intervals, wherein the two second gears 63 are connected by a transmission shaft 66, and one of the second gears 63 is meshed with the first gear 62. Since the connecting plate 21 has a certain length, the two groups of transmission assemblies are arranged horizontally and synchronously transmitted by the transmission shaft 66, so that the extrusion force in the length direction of the connecting plate 21 is balanced, thereby improving the clamping force of the extrusion plate 50 on the connecting plate 21.

[0035] As an example, see Figure 4 The transmission components can also be provided with four groups, and the four groups of transmission components form a rectangular arrangement, two of which are respectively engaged with the first gear 62, and the other two groups are respectively connected to the transmission shaft 66 for transmission, so that the upper, lower, left and right sides of the connecting plate 21 can have extrusion force at the same time, making the extrusion force more balanced, saving effort and being able to improve the clamping force of the extrusion plate 50 on the connecting plate 21.

[0036] As an example, a telescopic rod 67 is inserted into the first spring 65, and the two ends of the telescopic rod 67 are respectively connected to one end of the rack 64 and the inner wall of the connecting groove 11. By arranging the telescopic rod 67 between the rack 64 and the inner wall of the connecting groove 11, the first spring 65 is sleeved on the outside of the telescopic rod 67, which can provide support force for the rack 64 and the extrusion plate 50 on the one hand, and provide guidance and support for the spring on the other hand.

[0037] As an example, protective plates 22 are further provided on both sides of the cover plate, and the protective plates 22 are located on the outside of the connecting plate 21 and are smaller than the length of the connecting plate 21; when the connecting plate 21 is inserted into the connecting groove 11, the protective plates 22 are in contact with the outer wall of the bus duct carrier 10. By arranging the protective plates 22 at the outermost side, when the upper cover plate 20 is connected to the bus duct carrier 10, the protective plates 22 can prevent dust and water inside the bus duct carrier 10, and have a high protection performance.

[0038] In the embodiment of the present application, the elastic extrusion structure includes an abutment plate 71, a spring sheet 72, and a second spring 73. The abutment plate 71 is arranged on the outside of the support frame 40 and is connected to the support frame 40 through the second spring 73. At least two spring sheets 72 are provided, and the two spring sheets 72 are respectively connected between the abutment plate 71 and the outer wall of the support frame 40. The spring sheet 72 is connected in an eight-shaped inclined manner, and the end with a larger opening is connected to one side of the support frame 40, so as to facilitate the extrusion operation. Through the structure of the spring sheet 72 and the second spring 73, the abutment plate 71 can approach or move away from the side wall of the support frame 40, and it has an elastic extrusion force. When the support frame 40 is set inside the bus duct carrier 10, the abutment plate 71 is pressed against the inner wall of the bus duct carrier 10 under the elastic action of the second spring 73, thereby fixing the conductive bar 30 inside the bus duct carrier 10. When disassembly is required, the spring sheet 72 is pressed to move the abutting plate 71 closer to one side of the supporting frame 40 , and the supporting frame 40 can be taken out.

[0039] As an example, the area of ​​the abutment plate 71 is smaller than the area of ​​the side wall of the support frame 40. The smaller the area of ​​the abutment plate 71, the greater the squeezing force and the better the abutment.

[0040] As an example, the support frame 40 includes a bottom plate 42 and a copper bar support collar 41 fixed on the bottom plate 42 , and the outer wall of the copper bar support collar 41 is covered with an outer plate for connecting with the elastic extrusion structure.
