[0002] With the emergence of modern engineering facilities and equipment, electricity consumption in all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories and workshops. Traditional cables, used as transmission conductors, can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and connection. Therefore, busbar duct transmission systems, which are equivalent to traditional cables, have emerged on the market. Busbar duct transmission systems are power distribution devices capable of carrying high currents. Compared with traditional cables, they fully demonstrate their superiority in high-current transmission.

[0003] The effectiveness of busbar trunking transmission systems in transmitting current is largely influenced by busbar trunking connectors. Existing busbar trunking connectors are composed of conductors, insulating partitions, side panels, and connecting bolts. The insulating partitions are often made of Bakelite, epoxy resin, or plastic. Epoxy resin products are non-biodegradable and environmentally unfriendly, while plastic products have low protection standards and are prone to breakage and aging. Existing connectors have a small conductor contact area, resulting in poor overload capacity and a tendency for the joints to age and burn out. Summary of the Invention

[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific embodiments.

[0033] like Figure 1 and Figure 2 As shown, the bus duct connector includes a locking assembly 3, multiple conductors 1, and two side plates 2. The multiple conductors 1 are spaced apart along a first direction. Each conductor 1 includes a connecting portion 12 and two plug-in portions 11 disposed at both ends of the connecting portion 12 along a second direction. The first direction is perpendicular to the second direction. The two plug-in portions 11 are both used to plug into the bus duct. The width of the plug-in portions 11 along the first direction is greater than the width of the connecting portion 12 along the first direction. The two side plates 2 are spaced apart along the first direction, and the multiple conductors 1 are located between the two side plates 2. The locking assembly 3 includes a connecting rod 31, and each connecting portion 12 and the two side plates 2 are disposed on the connecting rod 31. It can be understood that the connecting rod 31 of the locking assembly 3 locks the relative positions of the multiple conductors 1 and the two side plates 2, and the two bus ducts are connected through the bus duct connector, thereby achieving the purpose of current transmission. In this embodiment, the width of the plug-in portion 11 along the first direction is greater than the width of the connecting portion 12 along the first direction, which can form a safe distance between two adjacent connecting portions 12 to achieve the purpose of insulation, thereby avoiding the use of insulating partitions, and solving the problems in the prior art that the insulating partitions are easily damaged, aged, and cause environmental pollution, as well as the problem of affecting the service life of the entire bus duct connector.

[0034] In the embodiment, the plug-in parts 11 at both ends of each conductor 1 and the connecting part 12 in the middle are formed with U-shaped grooves on both sides of the second direction, which are open to the first direction, and the depth of the U-shaped grooves is not less than one half of the creepage distance of the conductor 1, so as to ensure that a sufficient insulation creepage distance is formed between any two adjacent conductors 1, to meet the electrical insulation requirements, while the plurality of conductors 1 are closely arranged, which not only has high mechanical strength, but also has excellent contact surface and heat dissipation, so as to improve the overload capacity of the bus duct connector, and reduce the problem of aging and burning in the plug-in part 11. The bus duct connector adopts an inner plug-in structure, and the conductor 1 and the bus duct can form a reliable contact surface, so as to ensure that the bus duct system does not need to consider the capacity reduction regardless of the installation method, and can meet the requirements of eliminating harmonics in various power systems, and will not be affected by the temperature rise of overcurrent on the bus duct system.

[0035] Optionally, the plurality of conductors 1 are made of copper or aluminum. In the embodiment, in order to improve the power transmission capacity of the bus duct connector, high-quality conductive copper is used for the plurality of conductors 1, and the two plug-in parts 11 and the connecting part 12 in the middle are integrally arranged, which can fully utilize the plasticity of copper, and the connecting rod 31 passes through the connecting part 12 in the middle; in order to further increase the insulation effect between the adjacent connecting parts 12, in the embodiment, the conductor 1 is four and the connecting part 12 of each conductor 1 is subjected to corresponding insulation treatment, which can effectively balance various impedances, so as to greatly reduce the problems of unbalanced moment and the like existing in the installation of the bus duct connector. In other embodiments, different numbers of conductors 1 can be selected according to the use requirements, and the conductors 1 can also be made of other conductive materials.

[0036] Optionally, the two side plates 2 are made of aluminum profiles. In the embodiment, the two side plates 2 are made of aluminum alloy, which not only has high mechanical strength, but also has excellent corrosion resistance and heat dissipation, and can be used as 100% grounding conductor, and can effectively balance various impedances, so as to greatly improve the safety performance of the bus duct connector.

[0037] Optionally, as Figure 1As shown, the bus duct connector also includes two first positioning members 4, each made of an insulating material, and disposed on the connecting rod 31, and at least one second positioning member 5, also made of the insulating material. A second positioning member 5 is disposed between each adjacent connecting portion 12, and a first positioning member 4 is disposed between each side plate 2 and its adjacent connecting portion 12. It is understood that the first and second positioning members 4, 5 not only secure the position of each conductor 1 but also provide insulation. In this embodiment, there are three second positioning members 5, each of which is of equal shape and size. This ensures uniform spacing between the stacked conductors 1, thereby enhancing the aesthetics of the bus duct connector and making it more convenient and quick to install. In other embodiments, the number of second positioning members 5 can be adjusted based on the number of conductors 1, the shape and size of the first and second positioning members 4, 5 can also vary, and the spacing between multiple conductors 1 can be adjusted based on usage needs.

[0038] Optionally, the first positioning member 4 and the second positioning member 5 are both made of elastic material. In this embodiment, the first positioning member 4 and the second positioning member 5 are both elastic silicone. In other embodiments, the first positioning member 4 and the second positioning member 5 can also be made of other materials.

[0039] Alternatively, as Figure 1 As shown, the connecting rod 31 is a bolt, and the locking assembly 3 also includes a nut 32 and two washers 33. The two washers 33, the multiple conductors 1, and the two side panels 2 are all inserted into the bolt. The two side panels 2 are located between the two washers 33 and abut against the two washers 33 respectively. The nut 32 is threaded onto the bolt and abuts against one of the washers 33. In this embodiment, the bolt and nut 32 cooperate to lock the two side panels 2 and the multiple conductors 1 in position. To prevent electrical conduction between the bolt and the conductor 1, the bolt is an insulating bolt. It will be understood that the two washers 33 prevent the bolt head and nut 32 from directly contacting the two side panels 2, preventing damage to the side panels 2 when the bolt is tightened. In other embodiments, the connecting rod 31 can also have other structures, only needing to ensure insulation, and the locking assembly 3 can also adopt other structural forms, only needing to ensure that the conductor 1 and the side panels 2 are locked in position.

[0040] Optionally, the gaskets 33 are elastic and bowl-shaped, with the outer edge of each gasket 33 abutting the corresponding side panel 2. It will be appreciated that bowl-shaped elastic gaskets are stronger and can provide a more uniform clamping force to the side panel 2, thereby ensuring the reliable locking of the locking assembly 3. In other embodiments, gaskets 33 of other shapes may be used depending on the application requirements.

[0041] Alternatively, as Figure 1As shown, the side plates 2 are provided with first limiting parts 22 away from the conductors 1, and the first limiting parts 22 can abut against the outer edges of the gaskets 33 along the radial direction of the gaskets 33. It can be understood that the first limiting parts 22 can limit the deformation of the gaskets 33 in the radial direction, so as to guarantee the use effect of the gaskets 33. In other embodiments, the first limiting parts 22 can not be provided, and only the deformation of the gaskets 33 in the radial direction needs to be limited.

[0042] Optionally, the first limiting parts 22 are provided with second limiting parts 23, the second limiting parts 23, the first limiting parts 22 and the side plates 2 form a C-shaped accommodating cavity, the gaskets 33 are located in the accommodating cavity, and the second limiting parts 23 can prevent the gaskets 33 from being separated from the accommodating cavity. It can be understood that the gaskets 33 are arranged in the accommodating cavity, when the bolts are locked, the bolt heads and the nuts 32 abut against the two gaskets 33 respectively, the gaskets 33 are elastically deformed under the pressure, and the second limiting parts 23 can limit the deformation of the gaskets 33 in the axial direction. In other embodiments, the second limiting parts 23 can not be provided, and only the gaskets 33 need to be placed in the accommodating cavity and not separated from the accommodating cavity when deformed.

[0043] Optionally, as shown in the drawings, Figure 1 The two side plates 2 are provided with grooves 21 close to the conductors 1, and the first positioning members 4 abut against the groove walls of the corresponding grooves 21. It can be understood that the grooves 21 can increase the distance between the side plates 2 and the connecting parts 12 of the adjacent conductors 1, so as to meet the creepage insulation requirement of the side plates 2 and the conductors 1.

[0044] In the embodiment, the grooves 21 are U-shaped. It can be understood that the U-shaped grooves are convenient to process, and in other embodiments, the grooves 21 can also be provided in other shapes.

[0045] Obviously, the above embodiments of the application are only examples for clearly illustrating the application, and are not intended to limit the implementation modes of the application. Based on the above description, any other different forms of changes or modifications can be made by those skilled in the art. Here, all the implementation modes need not and cannot be exhausted.
