Description

Technical Field

[0001] This utility model belongs to the field of power transmission, and in particular relates to a novel two-piece busbar trunking profile. Background Technology

[0002] Busbar trunking is an electrical device used for power transmission and distribution. It consists of conductive bars, insulating materials, and a protective housing, and is capable of safely carrying large currents. In modern industrial and building power distribution systems, busbar trunking is widely used due to its excellent heat dissipation, high current carrying capacity, and ease of installation and maintenance. Busbar trunking not only meets the needs of high-capacity power transmission but also allows for flexible layout through modular design, making it suitable for power distribution in various complex environments.

[0003] Traditional busbar trunking enclosures are typically manufactured using a four-piece structure, consisting of two cover plates and two side plates. This design ensures that the busbar trunking has sufficient mechanical strength and good sealing performance to meet the needs of use in harsh environments such as outdoor or humid conditions.

[0004] While four-piece busbar trunking boasts excellent aesthetics and functionality, it reveals several shortcomings in practical applications. The manufacturing process requires multiple disassemblies and reassemblies, increasing labor intensity and production time. The precision machining and assembly of multiple components not only raises production costs but also reduces processing efficiency. Furthermore, installation and maintenance are complex, and there is some material waste. Firstly, from a manufacturing perspective, and secondly, regarding waterproofing, the drainage holes need to penetrate both sides of the outer shell, making it difficult to achieve ideal waterproofing between the shell layers. Especially after long-term use, moisture infiltration may occur, affecting the safety and lifespan of the busbar trunking. Utility Model Content

[0005] The purpose of this utility model is to provide a novel two-piece busbar profile to solve the technical problem of improving the waterproof and drainage effect of busbars while increasing processing efficiency.

[0006] To achieve the above objectives, the specific technical solution of this utility model for a novel two-piece busbar trunking profile is as follows:

[0007] A novel two-piece busbar profile includes a first outer shell and a second outer shell;

[0008] The first outer shell protrudes toward the second outer shell to form a first connecting portion, the first connecting portion including first connecting plates on both sides, and a first side plate connecting the two first connecting plates;

[0009] The second housing includes second connecting plates disposed on both sides, and second side plates connecting the second connecting plates, wherein the two second connecting plates and the second side plates are recessed toward the first housing to form a second connecting portion;

[0010] After the first connecting part enters the second connecting part, it connects the first connecting plate and the second connecting plate to realize the assembly of the first shell and the second shell;

[0011] A plurality of drainage holes are formed along the outer side of the second side plate opposite to the second connecting part on the surface of the second connecting plate.

[0012] As a further improvement of this utility model, the first connecting part protrudes in a bent shape toward the second outer shell, the bend is at a right angle, and the first connecting plate extends from the bend to both sides to form a limiting part.

[0013] As a further improvement of this utility model, the two second connecting plates are arranged in parallel, the second side plate is perpendicularly connected to the second connecting plate, and the inner end face of the second side plate facing the first side plate matches the protruding end face of the first connecting part.

[0014] As a further improvement of this utility model, after the first connecting part enters the second connecting part, the outer side of the first connecting plate is tightly attached to the inner side of the second connecting plate, and the top of the second connecting plate abuts against the limiting part.

[0015] As a further improvement of this utility model, when placed horizontally, the second outer shell is positioned above the first outer shell.

[0016] As a further improvement of this utility model, the first connecting plate and the second connecting plate are respectively provided with through connecting holes at their abutment points, and the connecting holes connect the first outer shell and the second outer shell by bolts.

[0017] As a further improvement of this utility model, the first side plate and the second side plate are respectively provided with protruding heat dissipation structures on the outer sides of the first connecting part and the second connecting part.

[0018] As a further improvement of this utility model, a guide groove connected to the drain hole is provided on the outer side surface of the second side plate relative to the second connecting part.

[0019] As a further improvement of this utility model, the guide groove is arranged perpendicularly to the second connecting plate on the surface of the second side plate.

[0020] As a further improvement of this utility model, the drainage holes are evenly spaced and symmetrically arranged on the two second connecting plates.

[0021] Beneficial effects:

[0022] This utility model's busbar profile adopts a two-piece design, namely a first outer shell and a second outer shell, replacing the traditional four-piece structure. This design significantly reduces the number of parts, simplifies the assembly process, improves production efficiency, and lowers manufacturing costs. Furthermore, the two-piece design makes the product more convenient and faster to transport and install, reducing logistics costs and construction difficulty.

[0023] Several drainage holes are provided on the second connecting plate. This design not only ensures effective drainage of water even under extreme weather conditions when the busbar trunking is installed horizontally, preventing moisture from entering the busbar trunking, but also avoids the waterproofing problems caused by the superposition of multiple shells in the traditional four-piece structure, since the drainage holes only need to pass through a single shell (the second shell), thus significantly improving the waterproofing performance of the product.

[0024] By setting corresponding connecting holes at the contact positions of the first and second connecting plates and fixing them with bolts, a tight fit between the first and second outer shells is ensured, enhancing the stability and reliability of the overall structure. Even in vibrating or shaking working environments, a good connection is maintained, extending the service life of the busbar trunking.

[0025] Both the first and second side plates are designed with raised heat dissipation structures on their outer sides. These structures effectively increase the surface area in contact with air, accelerating heat dissipation and thus improving the overall heat dissipation efficiency of the busbar trunking. This ensures that the temperature is controlled within a reasonable range during long-term operation, guaranteeing the safety and stability of the system. Simultaneously, guide channels are provided on the heat dissipation structures to ensure that accumulated water collects along the concave parts of the heat dissipation structures, flows into the guide channels, and finally exits through the drain holes.

[0026] In summary, the novel two-piece busbar profile provided by this utility model not only solves the problems of low processing efficiency and poor waterproof performance of traditional four-piece busbars, but also improves the product's installation convenience, waterproof performance and heat dissipation performance through a series of innovative designs, providing a more reliable option for power transmission and distribution.

Detailed Implementation

[0030] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0031] Implementation example:

[0032] like Figure 1 The diagram illustrates a novel two-piece busbar profile. When the busbar is placed horizontally, it includes a second outer shell 20 on top and a first outer shell 10 on the bottom. The first outer shell 10 and the second outer shell 20 are assembled using bolts installed through connecting holes 40 formed by side stamping. The second outer shell 20 has drainage holes 30 on its side, through which accumulated water is discharged from the side. Water is discharged only through the second outer shell 20, avoiding the risk of water flowing into the busbar through the gaps between the outer shells.

[0033] like Figure 2 As shown, the first outer shell 10 is U-shaped, with its protruding end facing the second outer shell 20. The protruding end face is the first side plate 12, and the first connecting plate 11 is connected to both sides of the first side plate 12. The first connecting plate 11 is bent at 90°, and limiting parts 14 are formed on both sides of the bend. At the same time, the first connecting plate 11 and the first side plate 12 are perpendicularly connected. The second outer shell 20 is H-shaped, with the second side plate 22 connecting the second connecting plates 21 on both sides at the middle, forming a perpendicular connection. The first side plate 12 and the first connecting plates 11 on both sides form the first connecting part 13. The second side plate 22 and the second connecting plates 21 on both sides form the second connecting part 23 facing the concave part of the first outer shell 10. The protrusion of the first connecting part 13 matches the shape and size of the opening groove of the second connecting part 23. The second connecting part 23 is sleeved on the first connecting part 13 to realize the connection between the first outer shell 10 and the second outer shell 20. After the top of the second connecting plate 21 abuts against the limiting part 14 at the bend of the first connecting plate 11, the sides of the first connecting plate 11 and the second connecting plate 21 are in a close-fitting abutting state. The close-fitting part is provided with a connecting hole 40, and a bolt passes through the connecting hole 40 to fix the first connecting plate 11 and the second connecting plate 21 together. The outer surfaces of the opposite connection parts of the first side plate 12 and the second side plate 22 are provided with heat dissipation teeth as a heat dissipation structure.

[0034] Along the back side of the second side plate 22 opposite to the second connecting part 23 (i.e., the outer side of the busbar trough), a drainage hole 30 is formed through the second connecting plate 21. The drainage hole 30 only passes through the second connecting plate 21 and has no path to flow into the busbar trough. At the same time, a guide groove is provided on the heat dissipation structure on the surface of the second side plate 22 to facilitate better drainage of surface water from the side. The drainage holes 30 are evenly spaced and symmetrically arranged on the sides of the two second connecting plates 21, and are connected in pairs by the guide groove. Accumulated water is collected through the grooves of the heat dissipation teeth, flows into the guide groove, and is discharged through the drainage hole 30.

[0035] The two-piece design of this utility model allows the drainage holes to exist independently, without communicating with the internal conductor space, achieving a safe drainage effect without affecting the safety and performance of the conductors inside the busbar trunking. The independent drainage holes significantly improve the waterproof performance of the busbar trunking profile. The drainage hole design does not penetrate the outer shell layer of the busbar trunking, thus preventing moisture from seeping into the busbar trunking and protecting the conductors from moisture. Simultaneously, the two-piece design makes the installation of the busbar trunking simpler and faster. Assembly is completed simply by inserting the connecting part of the first shell into the connecting part of the second shell and tightening the bolts, greatly reducing installation workload and time. This novel two-piece busbar trunking profile demonstrates significant improvements and advantages in production efficiency, drainage design, waterproof performance, installation convenience, structural stability, heat dissipation performance, and flow guidance design, providing users with a more efficient, safe, and reliable power transmission solution.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
