TECHNICAL FIELD
[0001] The present application relates to the technical field of bus duct, in particular to a bus duct connecting structure and a connecting method thereof. BACKGROUND
[0002] A bus duct is a kind of power distribution device for efficient current transmission, which is composed of a metal shell (usually made of aluminum alloy or steel), a conductive bar, and insulating materials. It has the advantages of large current-carrying capacity, high protection level, flexible power distribution, easy installation and maintenance, etc. It has been widely used in modern high-rise buildings, factories, commercial centers and other places of power supply and distribution system. The conductive bar of the bus duct is usually made of high-quality copper or aluminum, and its surface is specially treated to have good electrical conductivity and corrosion resistance. The insulating material is selected from materials with high insulation strength, high temperature resistance and aging resistance, such as polyester film and polycarbonate, to ensure the safety and reliability of the bus duct during long-term operation.
[0003] The bus duct is generally designed to be short, and it usually needs to be assembled (combined installation) to obtain the appropriate length before use, because the longer bus duct has large volume and heavy weight, which brings great difficulty to transportation and handling. The space of the transport vehicle is limited, and the height and width limits of the road also restrict the length of the transported bus duct. Moreover, the longer bus duct is difficult to handle due to its own weight and size, which is easy to cause damage. In addition, when the bus duct fails or reaches the service life and needs to be replaced during use, the shorter bus duct can be more conveniently disassembled, repaired or replaced locally, which reduces the maintenance cost and time and reduces the impact on the entire power supply system.
[0004] When multiple bus ducts are connected, a connector is generally provided, and a connecting cover plate is needed to cover the connector to prevent dust and water vapor from entering the connector and causing oxidation or leakage of the connector. The current connecting cover plate generally only uses several ordinary plastic plates for surrounding installation, which is very inconvenient to install. Moreover, the plastic plate and the bus duct are one component, and the gap between the plastic plate and the bus duct is large, the electrical connection between the bus ducts is not stable, the waterproof and dustproof effect is not good, and safety hazards are easy to occur. SUMMARY
[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a quick-assembly and disassembly busbar trunking connection structure and method. This addresses the common problem that when connecting multiple busbar trunking sections, connectors are typically installed, requiring connection covers to shield them and prevent dust and moisture from entering and causing oxidation or leakage. Current connection covers generally use only a few ordinary plastic sheets for enclosing installation, which is very inconvenient. Furthermore, with each plastic sheet and busbar trunking section treated as a separate component, the gap between the plastic sheets and the busbar trunking is relatively large, resulting in unstable electrical connections between different busbar trunking sections. This also leads to poor waterproofing and dustproofing, potentially causing safety hazards.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A busbar trunking connection structure that allows for quick assembly and disassembly includes a busbar trunking housing and a connecting assembly disposed between two adjacent busbar trunking housings. The busbar trunking housing has a first connecting plate symmetrically arranged on both sides of one end, a second connecting plate symmetrically arranged on both sides of the other end, guide blocks symmetrically arranged on both sides of the top of the busbar trunking housing, and mating grooves symmetrically opened on both sides of the bottom of the busbar trunking housing.
[0008] The connecting assembly includes a mounting plate, on both sides of which support plates are symmetrically arranged. A traveling plate parallel to the support plate is arranged on the inner side of the support plate. Baffles are symmetrically arranged on both sides of the traveling plate. A connecting groove is formed between the two baffles for the first and second connecting plates to engage. A drive threaded hole is opened through the support plate. A drive threaded rod with one end rotatably connected to the traveling plate is screwed into the drive threaded hole. An extension plate integrally formed with the support plate is provided on the top of the support plate. A locking plate is slidably arranged on the extension plate.
[0009] As a preferred embodiment of the present invention, the first connecting plate is provided with a fastening plate, and the second connecting plate is provided with a fastening groove for the fastening plate to be inserted.

[0011] As a preferred embodiment of the present invention, the top end face of the mounting plate is provided with a docking block that can be inserted into the docking groove at one end.
[0012] By using the above technical solution and the setting of docking blocks and docking grooves, the connection strength and stability between the busbar trunking shell and the connecting components are improved.
[0013] As a preferred embodiment of the present invention, a guide rod with one end connected to the traveling plate is slidably provided on the support plate on both sides of the drive threaded hole.
[0014] By using the above technical solution and the guide rod, the stability of the traveling plate during displacement is improved, ensuring that the traveling plate will not deviate.
[0015] As a preferred embodiment of the present invention, the top end face of the locking plate is provided with a fixed threaded half column, and two fixed threaded half columns can form a complete fixed threaded column, and a fixed nut is screwed onto the fixed threaded column.
[0016] The above technical solution utilizes a fixed nut in conjunction with two fixed threaded half-pillars to form a fixed threaded post, thereby enabling the top of the two busbar trunking housings to be locked.
[0017] As a preferred embodiment of the present invention, a limiting block is provided on the top end face of the extension plate, and a limiting groove for the displacement of the limiting block is provided on the bottom end face of the locking plate.
[0018] By using the above technical solution, the displacement stroke of the locking plate can be limited by the setting of the limiting groove and the limiting block.
[0019] As a preferred embodiment of the present invention, guide grooves for inserting guide blocks are provided on the bottom end faces of the locking plates on both sides of the limiting groove.
[0020] By using the above technical solution and the setting of guide grooves and guide blocks, the connection strength between the housings of the two busbar trunkings and the top of the connecting assembly is improved.
[0021] The present invention also provides a connection method for a busbar trunking connection structure that allows for quick assembly and disassembly, comprising the following steps:
[0022] S1. First, align and insert the mating groove on one of the busbar trunking shells with the mating block in the connecting assembly, so that one end of the mating block is inserted into the mating groove. Connect the other busbar trunking shell to the connecting assembly in the same way, so that the two busbar trunking shells are initially connected to the connecting assembly.
[0023] S2. In step S1, the fastening plate on one busbar housing is inserted into the fastening groove in the other busbar housing, so that the first connecting plate and the second connecting plate are in contact.
[0024] S3. Tighten the drive threaded rod to move the travel plate and the two baffles, so that the first connecting plate and the second connecting plate that are in contact with each other are locked into the connecting groove, and the connection between the two busbar housings is tightened.
[0025] S4. Push the locking plate to move so that the guide block on the busbar housing is engaged in the guide groove at the bottom of the locking plate. The two locking plates close together, causing the two fixed threaded half-columns to fit together to form a complete fixed threaded column. Screw the fixing nut onto the fixed threaded column to complete the connection and installation of the two busbar housings and the connecting assembly.
[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] The present invention, through the design of the connecting components, facilitates the disassembly and installation of two adjacent busbar trunking shells by the operators, while improving the connection strength and stability of the two adjacent busbar trunking shells.
