Technical Field
[0001] This utility model relates to a power distribution system for a terminal busbar, and more particularly to a sliding rail type terminal busbar housing and connection structure. Background Technology
[0002] In existing busbar systems, the outer casing of the terminal busbar typically employs a traditional fixed structure, such as... Figure 2 This structure presents numerous inconveniences during installation and maintenance, making it difficult to achieve flexible positioning and reliable connections, resulting in low installation efficiency and insufficient stability. When it is necessary to connect or repair the internal busbars, the limited operating space makes it difficult to complete the work quickly and efficiently. Furthermore, the heat dissipation performance of the traditional casing needs improvement, failing to meet the ever-increasing demands for power transmission. Summary of the Invention
[0003] The technical problem to be solved by this utility model is to provide a sliding rail type end busbar housing and connection structure that has more reliable connection, is easier to disassemble and install, and has better heat dissipation performance.
[0004] To solve the above-mentioned technical problems, the sliding rail type end busbar housing and connection structure of this utility model includes an outer shell integrally formed from aluminum profile. The outer shell consists of an upper top plate and two side plates. The upper top plate end face of the outer shell is provided with a sliding rail extending in the longitudinal direction. The upper and lower edges of the side plates are respectively provided with U-shaped fixing grooves with outward openings and extending longitudinally. The outer surface of the side plates has external accessories that are fixed by fasteners connected in a transverse manner. The front and rear end faces of the U-shaped fixing grooves are directly used as mounting holes for connecting fasteners.
[0005] The inner wall of the top plate is provided with a pair of L-shaped plates, and the inner wall of each side plate is provided with at least a pair of L-shaped plates. A mounting groove for fixing and installing the busbar trunking is formed between each pair of L-shaped plates.
[0006] The inner wall of the top plate is provided with a pair of L-shaped plates, and the L-shaped plates form a mounting groove for fixing and installing the busbar trunking. The inner walls of each side plate are provided with a pair of L-shaped plates on the upper and lower sides. The middle of the inner wall of each side plate is provided with a T-shaped plate, which separates the two L-shaped plates on the same side into two mounting grooves.
[0007] The slide rail has a C-shaped cross-section.
[0008] The side panels of the outer casing are provided with heat sinks extending upward and downward at both the upper and lower ends.
[0009] The heat sink has an arc-shaped cross-section.
[0010] The outer surface of the side plate of the casing and the upper surface of the top plate are provided with several longitudinally distributed heat dissipation strips.
[0011] The sliding rail type end busbar housing connection structure includes at least two sliding rail type end busbar housings and mounting plates for connecting adjacent housings. The adjacent side plates are aligned on the same plane by pressure plates, and the pressure plates are positioned and connected by fasteners that pass laterally into U-shaped fixing grooves. The top plate is provided with fixing holes, and the mounting plates are fixedly installed between adjacent top plates by fasteners passing through the fixing holes. The rear side of the housing is sealed by a sealing plate and fixed by fasteners inserted into the mounting holes.
[0012] The front side of the housing is provided with a limiting plate, which is limited by fasteners inserted laterally into the mounting holes.
[0013] The sealing plate is groove-shaped and is snapped onto the outer shell and fixed to the side plate by horizontal fasteners.
[0014] Advantages of this utility model:
[0015] (1) When the busbar needs to be maintained or expanded, the housing with U-shaped fixing groove is easy to disassemble and reinstall, making the operation more convenient and flexible, reducing maintenance costs and work difficulty, and improving the maintainability and expandability of the busbar housing.
[0016] (2) The top plate end face of the outer shell is provided with a slide rail extending in the longitudinal direction, which allows the busbar shell and related accessories to be quickly installed or adjusted in position by sliding.
[0017] (3) The upper and lower ends of the side plate of the outer casing are respectively provided with heat sinks extending to the upper and lower sides, which further optimizes the heat dissipation performance of the busbar.
[0018] (4) The end face of the U-shaped fixing groove is provided with mounting holes for inserting connectors to fix the sealing plate. The longitudinal direction of the U-shaped fixing groove can be connected to external accessories and limited by transverse fasteners. The U-shaped fixing groove increases the connection points, making the connection between the busbar and external accessories tighter and more secure, effectively reducing poor contact or electrical faults caused by vibration, loosening and other factors, and improving the reliability and safety of the entire sliding rail type end busbar housing connection structure.
