[0035] In the description of the present invention, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0036] Referring to Figures 1 to 3 , the new busbar of the embodiment of the present invention includes a conductor 500, two cover plates 400, two side plates 300, a sealing cover 100, and an end connection plate 200. Among them, the two cover plates 400 are respectively arranged on the upper and lower sides of the conductor 500, and the two cover plates 400 are symmetrically arranged on the upper and lower sides of the conductor 500. The two side plates 300 are respectively arranged on the left and right sides of the conductor 500, and the two side plates 300 are symmetrically arranged on the left and right sides of the conductor 500. As Figure 3 shown, the cross-sectional view of the entire busbar looks like a structure that is symmetric about the left and right, and at the same time, the conductor 500 can be centrally arranged in the frame formed by the side plates 300 and the sealing cover 100.

[0037] As Figure 3 shown, the cover plate 400 includes a cover plate body 410. On both sides of one end of the cover plate body 410 away from the conductor 500, first connectors 420 extend outward. Specifically, the two first connectors 420 are symmetrically arranged on both sides of one end of the cover plate body 410, so that the entire cover plate 400 is a structure that is symmetric about the left and right.

[0038] As Figure 3 shown, the side plate 300 includes a first connection portion 310 and a second connection portion 320. One side of the first connection portion 310 is smooth and fits the conductor 500, and the other side is provided with a heat dissipation structure, which is convenient for quickly dissipating the heat conducted from the conductor 500 to the side plate 300 into the air during the use of the busbar. In addition, a hollow structure is provided inside the first connection portion 310. Setting a hollow structure inside can ensure the strength of the side plate 300, effectively conduct heat, and also reduce the overall weight of the side plate 300. A second connection portion 320 is provided at a position near the heat dissipation structure at the end of the first connection portion 310, so that the first connection portion 310 and the second connection portion 320 form a step 350. Among them, second connection portions 320 are provided at both ends of the first connection portion 310. After enclosing and fittingly connecting the two cover plates 400 and the two side plates 300, asFigure 3 As shown, the cover plate body 410 abuts against the first connecting portion 310. The second connecting portion 320 fits against the side of the cover plate body 410 and is hermetically connected to the first connecting member 420, ensuring the close fit between the cover plate 400 and the side plate 300, and the leakage of the hermetically connected portion is convenient for visually checking whether the sealing is in place. Then, the second connecting portion 320 and the cover plate body 410 are fixedly connected by the first fastener 600. The first fastener 600 for connecting the cover plate 400 and the side plate 300 is arranged on the side, greatly reducing the overall width of the busbar trunking. In addition, the sealing cover 100 is snap-connected to the first connecting member 420 to protect the assembled busbar trunking from dust and water. Moreover, end connection plates 200 are arranged on both the front and rear sides of the conductor 500. The end connection plates 200 are connected to the side plate 300, and the arrangement of the end connection plates 200 facilitates the connection between each busbar trunking.

[0039] As Figure 4 and Figure 5 shown, the hollow structure includes a plurality of rectangular grooves 311 arranged in an array. A reinforcing rib 312 is provided between one set of diagonals of the rectangular groove 311. The arrangement of the reinforcing rib 312 can not only strengthen the overall structural rigidity of the first connecting portion 310, but also accelerate the heat conduction ability. Further, the heat dissipation structure includes a plurality of heat dissipation fins 340 arranged in an array. The heat dissipation fins 340 are connected to the junction of two adjacent rectangular grooves 311. The heat dissipation fins 340 are directly in contact with the fast heat transfer portion of the first connecting portion 310, improving the heat dissipation ability while enhancing the local structural strength, making the structure of the entire first connecting portion 310 more stable and the load it can bear also increasing. In addition, the hollow structure can also be a triangular groove or a circular groove. In this embodiment, the rectangular groove 311 is preferably selected. Among them, the array arrangement of the rectangular grooves 311 and the array arrangement of the heat dissipation fins 340 make the entire first connecting portion 310 have a left-right symmetric structural design, which is convenient for processing.

[0040] In some embodiments, the second connecting portion 320 is parallel to the first connecting portion 310, so that the cross-sectional shape of the side plate 300 is in an I shape, and as Figure 4As shown, two first connecting parts 310 are symmetrically arranged at both ends of the first connecting part 310, and the first connecting part 310 is close to the side with a heat dissipation structure, so that the whole side plate 300 has an up-and-down symmetrical structure style. In addition, the first connecting part 310 that needs to maintain structural rigidity in the side plate 300 is thickened, and a hollow structure is added inside. The second connecting part 320 that plays a connecting role is designed to be thin and light, and the second connecting part 320 is parallel to the first connecting part 310. The width of the whole side plate 300 depends on the thickness of the first connecting part 310. Compared with the side plate 300 of the traditional C-shaped structure, the side plate 300 of this embodiment is in an I shape. At the same time, in the busbar trunking after combination, the first fastener 600 that connects the cover plate 400 and the side plate 300 is arranged on the side, which greatly reduces the overall width of the busbar trunking. In addition, the unique symmetry of the cover plate 400 and the side plate 300 fully ensures that the busbar trunking can achieve an improvement in the protection level and the simplification of the processing and manufacturing of each component.

[0041] Furthermore, the second connecting part 320 and the first connecting part 310 are of an integral structure, and a connecting end 330 is arranged at the junction of the second connecting part 320 and the first connecting part 310. The connecting end 330 is connected to the end head connecting plate 200 through a second fastener. In this embodiment, the connecting end 330 is of a columnar structure, a through hole 331 is arranged in the middle of the columnar structure, internal threads are tapped at both ends of the through hole 331, and the second fastener is a bolt, and the bolt passes through the end head connecting plate 200 and then connects to the internal thread. The second connecting part 320 and the first connecting part 310 are integrally formed by die-casting aluminum alloy. The columnar connecting end 330 can strengthen the structural strength at the junction of the second connecting part 320 and the first connecting part 310. At the same time, the columnar connecting end 330 is also convenient for tapping holes on it, which is convenient for connecting the side plate 300 and the end head connecting plate 200. In the traditional connection structure, the end head connecting plate 200 is connected to the side plate 300 through a plugging piece, while in the embodiment of this application, the end head connecting plate 200 is directly connected to the side plate 300 through a bolt, which simplifies the connection mode.

[0042] As Figure 6 and Figure 7As shown, the cover plate body 410 is a U-shaped plate. On both sides of the open end of the U-shaped plate, first connecting pieces 420 extend outward. The first connecting pieces 420 are perpendicular to the U-shaped plate. Specifically, a first sealing groove 430 is provided at the junction of the first connecting piece 420 and the cover plate body 410. A circular silica gel strip 710 is provided in the first sealing groove 430. After the cover plate body 410 abuts against the first connecting portion 310, the second connecting portion 320 fits against the side of the cover plate body 410 and presses against the circular silica gel strip 710. Further, the side of the first connecting piece 420 that fits against the sealing cover 100 is recessed inward to form a second sealing groove 421, so that the other side of the first connecting piece 420 protrudes outward to form an arc-shaped first buckling portion 422. A circular silica gel strip 710 is also provided in the second sealing groove 421. As Figure 8 shown, the outer edges on both sides of the sealing cover 100 are bent to form second buckling portions 110 that cooperate with the first buckling portion 422. The left and right of the cover plate 400 are symmetrically structured. The first sealing groove 430 is provided at the corner, which is convenient for observing the presence or absence of the circular silica gel strip 710 that plays a sealing role, can ensure close fitting with the side plate 300, and the sealing connection part is exposed for intuitive inspection to check whether the circular silica gel strip 710 is omitted during assembly. The first connecting piece 420 protrudes to form an arc-shaped first buckling portion 422, which is convenient for the second buckling portion 110 of the sealing cover 100 to be buckled and installed with the first buckling portion 422.

[0043] In some other embodiments, the width of the first connecting portion 310 is greater than the width of the conductor 500. After the cover plate body 410 abuts against the first connecting portion 310, the cover plate body 410, the first connecting portion 310, and the conductor 500 form a cavity for storing the sealing silica gel 720. The design of this structure facilitates further enhancing the waterproof and dustproof performance of the conductor 500 of the busbar trunking.

[0044] It should be noted that the first fastener 600 is a rivet. The second connecting portion 320 and the cover plate body 410 are connected together by riveting. Compared with the method of connecting the side plate 300 and the cover plate 400 with bolts, the method of riveting can connect the side plate 300 and the cover plate 400 more quickly and the connection is also more firm.

[0045] In some other embodiments, as Figure 9 and Figure 10 shown, the end connection plate 200 includes a first connection plate 210 and a second connection plate 220. The first connection plate 210 is longer than the second connection plate 220. The first connection plate 210 and the second connection plate 220 are connected into an L-shaped structure, and a columnar connection bar 230 is provided at the connection of the first connection plate 210 and the second connection plate 220. A connection hole 231 penetrating both ends is provided on the connection bar 230. Internal threads can be tapped in the connection hole 231. The setting of the connection hole 231 facilitates the quick connection of the end connection plate 200 and the connection guard plate. AsFigure 1 As shown, each end of the conductor 500 is provided with two end connection plates 200, and the two end connection plates 200 are symmetrically arranged, wherein the second connection plate 220 fits the second connection part 320 and is connected to the connection end 330 on the second connection part 320 by bolts, and the first connection plate 210 is used to dock with the connection guard plate. In addition, a limiting boss 211 is designed on the outer side of the first connection plate 210, so that when the connector is plugged in, it can be intuitively observed whether the plug-in is in place, and it plays a role in preventing over-plugging.

[0046] Among them, due to the structural characteristics of the cross-section center of a single bus duct being completely symmetrical, the conductor 500 of the bus duct is ensured to be centrally arranged, and it is also convenient to expand the production of double-layer busbars. Figure 11 That is the cross-sectional structure diagram of a double-layer bus duct. In other embodiments, multi-layer bus ducts can also be stacked to form multi-layer bus ducts. When two bus ducts are stacked, the first connecting member 420 of one bus duct is aligned and fitted with the first connecting member 420 of another bus duct. After the fitting is completed, the two fitted first connecting members 420 are locked together by bolts to complete the production of the multi-layer bus duct. Since the cross-sectional center of a single bus duct is completely symmetrical, it is convenient to produce multi-layer bus ducts, and there is no need to do special processing to align the conductor 500.

[0047] Compared with the prior art, the embodiments of the present invention have at least the following beneficial effects:

[0048] 1. The sealing cover 100 and the cover plate 400 are tightly buckled together to protect the bus duct from dust and water after assembly;

[0049] 2. The first connecting piece 420 extends outwardly from both sides of the end of the cover body 410 away from the conductor 500, so that the cover 400 as a whole has a bilaterally symmetrical structure. The cover body 410 abuts against the first connecting portion 310, and the second connecting portion 320 fits the side of the cover body 410 and is sealed with the first connecting piece 420, so as to ensure that the cover 400 and the side plate 300 are closely fitted, and the sealed connection part is exposed to facilitate visual inspection of whether it is sealed in place;

[0050] 3. The upper and lower ends of the side plate 300 are symmetrical. One side of the first connection part 310 is attached to the conductor 500, and the other side is provided with a heat dissipation structure. The first connection part 310 is provided with a hollow structure inside. The heat dissipation structure can quickly dissipate the heat conducted from the conductor 500 to the side plate 300 into the air, thereby improving the heat dissipation capacity. The hollow structure inside can ensure the strength of the side plate 300 and effectively conduct heat.

[0051] 4. The provision of the terminal connection plate 200 facilitates the connection between the bus ducts.

[0052] Overall, compared with the prior art, the uniqueness of the cross-sectional structure of the busbar trunking is prominent; the structure of the side plate 300 is no longer the traditional C-shaped, and the connection is more convenient. The first fastener 600 connecting the cover plate 400 and the side plate 300 is arranged on the side, greatly reducing the overall width of the busbar trunking. In addition, the unique symmetry of the cover plate 400 and the side plate 300 fully ensures that the busbar trunking can achieve an improvement in the protection level and the simplification of the processing and manufacturing of each component. The side plate 300 and the end connection plate 200 are also different from the existing designs. The traditional sealing parts are removed. There are only 4 types of components that make up the busbar trunking as a whole, streamlining the types of components and simplifying the connection mode. After combining and connecting each component to surround the conductor 500, only the first fastener 600 is needed to connect the second connection part 320 and the cover plate body 410 together. After installing the sealing cover 100 and the end connection plate 200, the assembly of the dust-proof and waterproof busbar trunking can be completed. The assembly is convenient, and the cross-section center of the assembled busbar trunking is completely symmetrical, ensuring that the conductor 500 is centered, facilitating the expansion of the production of double-deck busbar trunkings, and at the same time making the connection deviation more refined.
