It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0060] like Figure 1 As shown, the utility model provides a bus duct system 1, which includes at least two bus ducts 10 and a connector 20. Two adjacent bus ducts 10 are connected by the connector 20. Figure 1 Schematically showing the end portions of two bus ducts 10, the end portions of the two bus ducts 10 are opposite and connected by a connector 20. The bus duct 10 can be any type of bus duct, illustratively, the bus duct 10 can be a straight-through bus duct, such as a slide rail straight-through bus duct.

[0061] like Figure 2 As shown, the bus duct 10 includes a shell 11 and a plurality of conductors 12. The shell 11 is long and has end openings at both ends of the length direction of the bus duct 10. The plurality of conductors 12 are arranged in the shell 11 and extend beyond the end openings of the shell 11. The plurality of conductors 12 may include, for example, a phase conductor 13 (L), a neutral conductor 14 (N) and a protective conductor 15 (PE). The number of the phase conductors 13 may be three, namely, a first phase conductor 13a, a second phase conductor 13b and a third phase conductor 13c, and one neutral conductor 14 and one protective conductor 15. Optionally, these conductors 12 may all be copper conductors 12. The bus duct 10 also includes a plug 16. The plug 16 is arranged at the two ends of the bus duct 10 in the length direction, specifically, the plug 16 is connected to the shell 11 and can block the end openings of the shell 11, and the plurality of conductors 12 pass through the plug 16. The plug 16 is made of insulating material, such as plastic material.

[0062] The plurality of conductors 12 are arranged at intervals in a first direction D1 and are parallel to a second direction D2 perpendicular to the first direction D1. In one example, the arrangement order is neutral conductor 14, third phase conductor 13c, second phase conductor 13b, first phase conductor 13a, and protective conductor 15. Of course, the arrangement order of the conductors 12 in this article is not limited. The plurality of conductors 12 of two adjacent bus ducts 10 are correspondingly connected through connectors 20. Taking the neutral conductor 14 among the plurality of conductors 12 as an example, the neutral conductor 14 of one bus duct 10 is connected to the neutral conductor 14 of another bus duct 10 through the connector 20.

[0063] The connector 20 adopts a structure similar to a dense connector. Figure 3 and Figure 4As shown, the connector 20 includes a plurality of partitions 21, two end cover plates 22 and bolts 23. The plurality of partitions 21 are arranged at intervals in a first direction D1 and are parallel to a second direction D2 perpendicular to the first direction D1, and a receiving cavity 24 is formed between two adjacent partitions 21. The number of receiving cavities 24 is the same as the number of conductors 12 of the bus duct 10. The plurality of partitions 21 are located between the two end cover plates 22, and the two end cover plates 22 are connected to the plurality of partitions 21 by bolts 23 along the first direction D1, and are locked by nuts 25 located at the ends of the bolts 23. Specifically, the bolts 23 pass through the center holes of the two end cover plates 22 and the center holes of the plurality of partitions 21, and then are locked at the ends of the bolts 23 with nuts 25. The various components of the connector 20 are connected together by a fastening connection method, and the overall structure of the connector 20 is more compact, and the assembly steps are simple and easy to operate.

[0064] The partition 21 includes a partition body 26 and a conductive connecting plate 27. The partition body 26 is an insulating member; one example is that the partition body 26 is made of an insulating material as a whole; another example is that an insulating layer is provided on the side of the partition body 26. The conductive connecting plate 27 is provided on the side of the partition body 26 and is used to be electrically connected to the conductor 12 of the bus duct 10. With the help of the insulated partition body 26, leakage at the connection between the conductive connecting plate 27 and the partition body 26 can be avoided, and the use safety of the connector 20 is higher.

[0065] Optionally, the bolt 23 is a stud bolt. The connector 20 has a higher assembly efficiency and a better tightening effect. When tightening, the first bolt head falls off, indicating that the connection is in place.

[0066] The connector 20 further includes a spacer 28. The spacer 28 is annular and is sleeved on the bolt 23 and located between two adjacent partitions 21. The spacer 28 is an insulating member; in one example, the spacer 28 is made entirely of insulating material; in another example, an insulating layer is provided on the outer circumference of the spacer 28. With the help of the insulating spacer 28, leakage at the bolt connection can be avoided, and the connector 20 is safer to use.

[0067] The partition 21 herein adopts an anti-misinstallation structure. Specifically, the plurality of partitions 21 include a first partition 31 and a second partition 32. The number of the first partitions 31 is greater than the number of the second partitions 32. For example, the number of the first partitions 31 is at least two, and the number of the second partitions 32 is one. As shown in the embodiment, the number of the first partitions 31 is three, and the number of the second partitions 32 is one.

[0068] The thickness of the second partition plate 32 is different from the thickness of the first partition plate 31. The connector 20 has a central reference plane P, Figure 4The schematic diagram shows the approximate position of the central reference plane P. The central reference plane P is located at the center of the connector 20 in the first direction D1 and is parallel to the second direction D2, and the second partition 32 is located on one side of the central reference plane P. In order to cooperate with the anti-misinstallation structure of the partition 21, a first conductor gap g1 and a second conductor gap g2 with different spacings are provided between two adjacent conductors 12 among the plurality of conductors 12. The first partition 31 corresponds to the first conductor gap g1, and the second partition 32 corresponds to the second conductor gap g2.

[0069] In this way, the connector 20 has two partitions 21 with different thicknesses, and the position of one of the partitions 21 avoids the center of the connector 20 and is set on a single side of the central reference plane P, so that the multiple partitions 21 are set asymmetrically as a whole. Multiple conductors 12 are arranged to have different gaps, so that the multiple conductors 12 are set asymmetrically as a whole. During assembly, the connection order between the conductors 12 of the bus duct 10 and the connector 20 is unique, thereby ensuring the connection between the conductors 12 of the same properties in adjacent bus ducts 10 and avoiding the disorder of the property order of the conductors 12 of adjacent bus ducts 10. The connector 20 provided in this embodiment has an anti-misinstallation structure, which is conducive to improving assembly efficiency and avoiding accidents caused by the disorder of the properties of the conductors 12.

[0070] In the illustrated embodiment, a first conductor gap g1 is provided between two adjacent conductors 12 among the neutral conductor 14, the third phase conductor 13c, the second phase conductor 13b, and the first phase conductor 13a, and a second conductor gap g2 is provided between the first phase conductor 13a and the protective conductor 15. The first partition 31 is used to separate two adjacent conductors 12 among the neutral conductor 14, the third phase conductor 13c, the second phase conductor 13b, and the first phase conductor 13a, and the second partition 32 is used to separate the first phase conductor 13a and the protective conductor 15.

[0071] Optionally, the thickness of the second partition 32 is greater than the thickness of the first partition 31, and correspondingly, the second conductor gap g2 is greater than the first conductor gap g1. Of course, if necessary and / or desired, the thickness of the second partition 32 is less than the thickness of the first partition 31, and correspondingly, the second conductor gap g2 is less than the first conductor gap g1. The thickness of the end partition 33 is less than the thickness of the second partition 32. The second partition 32 has a feature different from the end partition 33, which increases the obviousness of the error-proofing difference brought by the second partition 32, making it easier for the assembler to observe. The thickness of the end partition 33 is not much different from the thickness of the first partition 31.

[0072] There is a first partition spacing between two adjacent first partitions 31, and there is a second partition spacing between the second partition 32 and the adjacent first partition 31, and the second partition spacing is the same as the first partition spacing. There is a third partition spacing between the end partition 33 and the adjacent first partition 31 or second partition 32, and the third partition spacing is the same as the first partition spacing. The first partition 31, the second partition 32 and the end partition 33 are arranged with the same spacing, which is suitable for the case where multiple conductors 12 of the bus duct 10 have the same thickness. The structure of the connector 20 is simple and convenient for production and manufacturing.

[0073] Furthermore, if Figure 3 As shown, the end partition 33 may be provided with a limiting protrusion 34 protruding from the side of the end partition 33, which is used to limit the movement of the end cover plate 22 in the second direction D2 and the third direction D3 perpendicular to the first direction D1 and the second direction D2. By means of the limiting structure on the end partition 33, the movement of the end cover plate 22 is limited, so that the position of the end cover plate 22 relative to the partition 21 remains stable, which is conducive to providing a stable clamping force for multiple partitions 21, so that the overall structure of the connector 20 is more stable. Optionally, the limiting protrusions 34 can be arranged at intervals around the end cover plate 22, for example, the limiting protrusions 34 are located on both sides of the end cover plate 22 in the first direction D1, and on both sides of the second direction D2.

[0074] Optionally, the shape of the partition 21 corresponds to the shape of the end cover plate 22, for example, the partition 21 is a rectangle, and correspondingly, the end cover plate 22 is also a rectangle. The size of the partition 21 in the second direction D2 is greater than the size in the third direction D3, and correspondingly, the size of the end cover plate 22 in the second direction D2 is greater than the size in the third direction D3. The end cover plate 22 is also provided with side wings 35, which are located at both ends of the end cover plate 22 in the third direction D3 and extend along the second direction D2 so that the side wings 35 are formed into a long strip. A pressure plate 29 is provided on the outer side of the end cover plate 22 away from the partition 21, and the bolt 23 passes through the pressure plate 29 and locks the pressure plate 29 with the end cover plate 22 with the nut 25. The size of the pressure plate 29 is smaller than the end cover plate 22, and the shape of the pressure plate 29 corresponds to the shape of the end cover plate 22, for example, it is also a rectangle.

[0075] Optionally, both end surfaces of the first partition 31 and the second partition 32 in the first direction D1 may be provided with a guide portion 36. The guide portion 36 extends in a third direction D3 perpendicular to the first direction D1 and the second direction D2, so that the guide portion 36 is formed into a long strip. During assembly, the guide portion 36 can provide guidance to the conductor 12 of the bus duct 10, and the conductor 12 can be easily inserted into the accommodating cavity 24 under the guidance of the guide portion 36, thereby improving assembly efficiency.
