Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a busbar for cable trays. Background Technology

[0002] Busbar trunking is a type of electrical equipment used for transmitting and distributing electrical energy. It mainly consists of conductive bars, insulating supports, and a metal casing. It boasts advantages such as compact structure, high current carrying capacity, good heat dissipation, and high safety, and is widely used in large factories, data centers, and high-rise buildings. In practical applications, busbar trunking needs to be combined with multiple structural sections and form a stable connection with cable trays. This places higher demands on the precision, sealing, and ease of installation of its connection structure. Connectors are typically used for combining multiple busbar trunking sections. During connection, the busbars within the two busbar trunking sections must be aligned one-to-one. Then, the connecting pieces on the connector are aligned with the gaps between adjacent busbars and inserted into the connector. Finally, the upper and lower sealing covers are installed for sealing.

[0003] Existing busbar trunking systems mostly use simple bolt or clip connections, lacking effective guiding and positioning structures. This leads to misalignment when two busbar sections are joined, especially during connector insertion and tightening, often requiring repeated adjustments and impacting installation efficiency and connection stability. This is particularly problematic when replacing or repairing busbar trunking on cable trays, making the work extremely difficult. Therefore, there is an urgent need for a busbar trunking structure that is structurally sound, highly efficient in installation, precisely positioned, reliably sealed, and easy to connect and disassemble, in order to improve the overall system reliability and construction efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a busbar trough for cable trays.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A busbar trough for cable trays includes an outer casing, inside which a busbar assembly is fixedly installed, and a sealing cover is detachably installed on the top of the outer casing. Both ends of the busbar assembly extend out of the outer casing and outwards. Two first side sealing plates and two second side sealing plates are disposed at both ends of the outer casing. The two first side sealing plates are symmetrically arranged on both sides of one end of the busbar assembly, and the two second side sealing plates are also symmetrically arranged on both sides of the other end of the busbar assembly. A guide positioning mechanism includes two first connecting plates and two second connecting plates. The two first connecting plates have identical structures and are symmetrically arranged at the bottom of the two first side sealing plates. A semi-groove is formed near the ends of the surfaces of the two first connecting plates, and a slot is formed at the ends of the two first connecting plates. The two second connecting plates have identical structures and are symmetrically arranged at the bottom of the two second side sealing plates. An guide block corresponding to the semi-groove is fixedly connected to the ends of the two second connecting plates, and a locking block corresponding to the slot is fixedly connected to the ends of the two second connecting plates.

[0007] Preferably, the outer casing is fixed to the busbar assembly, the first side sealing plate, and the second side sealing plate by bolts.

[0008] Preferably, the half-groove has a semi-V-shaped structure, and the two half-grooves are symmetrical to each other and form a complete V-shaped groove.

[0009] Preferably, each of the two slots has a first threaded hole above it, and a bolt is fitted onto each of the two first threaded holes.

[0010] Preferably, the two blocks are provided with second threaded holes corresponding to the positions of the first threaded holes, and the first threaded holes and the second threaded holes can be connected to each other by bolts.

[0011] Preferably, a knob is fixedly connected to the top of the bolt.

[0012] This utility model has the following beneficial effects:

[0013] 1. In this utility model, the semi-V-shaped grooves on the first connecting plate and the second connecting plate, along with the guide block, the slot and the block, cooperate to achieve precise guiding and docking, while strengthening the stability of the connection and preventing misalignment of the busbar end.

[0014] 2. The present invention enhances safety through anti-detachment design: the card block and the card slot are used together and locked by the first threaded hole, the second threaded hole and the bolt, which effectively prevents the connecting parts from loosening or falling off, further improving the stability and safety in subsequent construction and operation, and also avoiding the connection of the connector being affected by the offset and misalignment of the end of the busbar groove during the connector insertion process.

[0015] 3. This utility model is highly convenient to operate. The top of the bolt is equipped with a knob structure, which allows for manual operation during installation or disassembly without the need for additional tools. This simplifies the on-site construction steps and facilitates subsequent disassembly and maintenance. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6A busbar trough for cable trays includes an outer casing 1, a busbar assembly 2 fixedly installed inside the outer casing 1, and a detachable sealing cover 3 installed on the top of the outer casing 1; both ends of the busbar assembly 2 extend out of the outer casing 1 and outwards; two first side sealing plates 4 and two second side sealing plates 5 are disposed at both ends of the outer casing 1, the two first side sealing plates 4 are symmetrical to each other and are respectively installed on both sides of one end of the busbar assembly 2, and the two second side sealing plates 5 are also symmetrical to each other and are respectively installed on both sides of the other end of the busbar assembly 2; a guide positioning mechanism, the guide positioning mechanism including two first connecting plates. The first connecting plates 6 and two second connecting plates 7 are identical in structure and symmetrically arranged at the bottom of the two first side sealing plates 4. The ends of the two first connecting plates 6 are provided with semi-grooves 601 near each other. The ends of the two first connecting plates 6 are provided with slots 602. The two second connecting plates 7 are identical in structure and symmetrically arranged at the bottom of the two second side sealing plates 5. The ends of the two second connecting plates 7 are fixedly connected with guide blocks 701 corresponding to the semi-grooves 601. The two second connecting plates 7 are fixedly connected with locking blocks 702 corresponding to the slots 602.

[0025] In this embodiment, the outer casing 1 serves as the main load-bearing structure of the busbar trunking, used to enclose and protect the internal busbar assembly 2, preventing damage to electrical components from the external environment. A removable sealing cover 3 is installed on its top for easy inspection and maintenance, improving convenience and safety. The busbar assembly 2, the core component for power transmission, is installed inside the outer casing. The first side sealing plate 4 and the second side sealing plate 5 are located at both ends of the outer casing, fixing and protecting the sides of the busbar assembly and improving its sealing performance. This effectively prevents dust and moisture from entering, contributing to improved overall sealing and structural stability of the busbar trunking system. The half-trough 601 adopts a semi-V-shaped design; the two half-troughs 601 combine to form a complete V-shaped groove, which, in conjunction with the guide block 701, provides excellent guiding functionality, enabling automatic alignment of the two busbar trunking sections during splicing and simplifying construction operations. The slot 602 and the block 702 provide reliable mechanical locking for the connection structure; they interlock to effectively prevent loosening or shifting after splicing, ensuring a robust structure.

[0026] In this utility model, the outer box 1 is fixed to the busbar group 2, the first side sealing plate 4 and the second side sealing plate 5 by bolts.

[0027] In this embodiment, bolts are used to achieve tight fixing between structural components, effectively preventing loosening and displacement caused by vibration or thermal expansion and contraction, thus improving the overall structural stability and service life of the busbar trunking. Compared to welding or riveting, bolted connections offer excellent disassembly, making maintenance, replacement of the internal busbar assembly 2, or cleaning of the outer casing 1 easier and faster, saving labor and time costs. The tightening force applied by the bolts ensures a tighter contact between the outer casing 1 and the sealing plates 4 and 5, improving the system's dustproof and moisture-proof performance and adapting to various complex environments. In summary, the bolted fixing structure not only enhances the structural strength and reliability of the busbar trunking but also improves its maintainability and applicability.

[0028] In this utility model, the half-groove 601 has a half-V-shaped structure, and the two half-grooves 601 are symmetrical to each other and form a complete V-shaped groove.

[0029] In this embodiment, the semi-groove 601 adopts a semi-V-shaped structure design. The V-shaped groove structure has natural self-positioning characteristics. After the two semi-V-shaped structures are joined together, a complete V-shaped groove is formed, which has good fitting characteristics. Through the cooperation between the V-shaped groove and the guide block, the connector can be "slid-in" to connect, reducing the installation difficulty and technical requirements, improving construction efficiency, and is suitable for rapid on-site installation or multi-segment connection operations. The symmetrical design of the V-shaped structure can provide self-calibration at the initial contact, avoiding angle deviation or misalignment problems that occur during manual installation. After assembly, it can effectively limit the displacement of the connecting parts in the lateral and longitudinal directions, and improve the connection firmness of the entire guide positioning mechanism.

[0030] In this utility model, each of the two slots 602 has a first threaded hole 603 above it, and each of the two first threaded holes 603 is fitted with a bolt 604.

[0031] In this embodiment, a 604 bolt structure is used for connection, which facilitates later maintenance and replacement. Users can quickly disassemble and assemble as needed during actual use. As a standard part, the 604 bolt is easy to install and flexible to adjust. Installers can complete the connection by simply tightening it, avoiding the need for complex tools or high-precision fitting, and facilitating rapid on-site operation.

[0032] In this utility model, two locking blocks 702 are provided with second threaded holes 703 corresponding to the positions of the first threaded holes 603, and the first threaded holes 603 and the second threaded holes 703 can be connected to each other by bolts 604.

[0033] In this embodiment, the first threaded hole 603 and the second threaded hole 703 are connected by bolt 604 to achieve a firm connection and efficient locking connection, which effectively enhances the overall stability of the guide positioning mechanism and avoids displacement or loosening between components. The first threaded hole 603 and the second threaded hole 703 are in one-to-one correspondence, which can accurately position the two connecting plates during the assembly process and ensure precise alignment when the structures at both ends of the busbar are connected.

[0034] In this utility model, a knob 605 is fixedly connected to the top of the bolt 604.

[0035] In this embodiment, by setting a knob 605 on the top of the bolt, the user can directly tighten or loosen the bolt manually without the need for tools such as wrenches, which greatly improves the convenience of installation and disassembly. The knob design makes the tightening action faster, which is especially suitable for bus trunking systems with multiple connection points on site. During equipment maintenance or replacement, the user can quickly loosen the knob bolt 604 to realize the rapid disassembly and replacement of bus trunking components, making maintenance work more efficient and flexible, saving construction time and improving work efficiency. Since no special tools are required, this knob structure can also be easily operated in situations where space is limited or tools cannot be used, making it more adaptable.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
