Description

Technical Field

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

[0002] The busbar trunking enclosure is a core external structural component and safety protection element of the busbar trunking system. Its core function is to provide mechanical support, electrical insulation, and environmental protection for the conductive bars carrying high currents inside. This enclosure is typically made of metal, forming a closed or semi-closed channel. Internally, multiple parallel conductive bars are reliably fixed and maintain sufficient insulation spacing through components such as insulating supports or insulating filler blocks. The enclosure structure not only bears the weight of the conductive bars and their insulation layers and the enormous electrodynamic forces generated during short circuits, but also isolates external dust, moisture, and foreign objects, preventing electric shock and ensuring the safe and efficient transmission of power within the closed channel. Simultaneously, the metal enclosure itself often serves as a grounding conductor, making it a crucial link in ensuring the safe operation of the power supply system. However, existing busbar trunking enclosures still suffer from inconvenience in disassembly, assembly, and subsequent maintenance.

[0003] Therefore, it is essential to invent a housing for busbar trunking. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a busbar trunking housing, resolving the issues of inconvenience in disassembly, assembly, and subsequent maintenance inherent in existing busbar trunking housings. The busbar trunking housing includes a lower supporting shell, an upper enclosing shell, an insulating filler block, a conductor, and an insulator. The upper enclosing shell is fixedly installed above the lower supporting shell, and the insulating filler block is disposed between the lower supporting shell and the upper enclosing shell. The conductor is disposed between the lower supporting shell and the insulating filler block. The conductor is externally wrapped with an insulator.

[0005] The lower support shell includes a bottom shell, a stabilizing block, a mounting slot, a locking groove, and a connecting shell. The stabilizing block is fixedly mounted on the bottom surface of the bottom shell, and the mounting slot is located inside the stabilizing block. The connecting shell is located above the bottom shell, and the locking groove is located between the bottom shell and the connecting shell.

[0006] The upper enclosed shell includes an enclosed shell, connecting side plates, gaskets, and connecting bolts. The connecting side plates are fixedly installed on both sides of the enclosed shell. The enclosed shell is engaged with the inner side of the engaging groove above the lower support shell through the connecting side plates. The gaskets are located on the outer side of the connecting side plates, and the connecting bolts are engaged inside the connecting side plates, the connecting shell, and the insulating filler block.

[0007] The bottom shell, locking groove, and connecting shell inside the lower support shell are integrated and supported by aluminum alloy metal plates. The locking groove is an outward-facing groove with a connecting side plate installed inside. The locking groove is an inward-facing groove with an insulating filler block installed inside. The stabilizing block and the insulating filler block adopt a long strip mica base, and the inside of the stabilizing block has a long strip groove to form an installation slot. This installation slot and the groove inside the insulating filler block together form several spaces to accommodate conductors and insulators.

[0008] The upper closed shell completely encloses the upper part of the lower support shell, and the connecting bolts are several internal hexagonal socket bolts. After the connecting bolts are removed outward, the upper closed shell and the insulating filler block can be pulled out or slid in from the lower support shell in sequence.

[0009] Compared with the prior art, the present invention has the following beneficial effects: The lower support shell of this utility model bears the main structural load through its bottom shell and enhances the overall rigidity by using its stabilizing block. The mounting slot inside the stabilizing block and the insulating filling block together form a space to accommodate the conductor and the insulator. At the same time, the locking groove formed between the connecting shell and the bottom shell provides a key locking and positioning interface for the connecting side plate of the upper closed shell. Through cooperation with the connecting bolts and gaskets, a stable connection with the closed shell is finally achieved.

[0010] The upper closed shell of this utility model, together with the lower supporting shell, forms a complete, safe, and easily openable closed structure. Its specific functions are as follows: the upper closed shell is initially positioned and mechanically connected by its connecting side plate engaging with the locking groove of the lower supporting shell. Connecting bolts and washers are then used to achieve final fastening with the lower supporting shell and insulating filler block. Thus, the closed shell completely seals the upper opening of the lower supporting shell, forming a protective cover to protect the internal conductors and insulators. Simultaneously, this design allows the entire upper closed shell, along with the insulating filler block, to be pulled out after the connecting bolts are removed, greatly facilitating the installation, inspection, and maintenance of the conductors.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0016] As attached Figure 1 To be continued Figure 3 As shown.

[0017] The present invention provides a housing for a busbar trunking, comprising a lower support shell 1, an upper closed shell 2, an insulating filler block 3, a conductor 4, and an insulator 5, wherein: the upper closed shell 2 is fixedly installed above the lower support shell 1, and the insulating filler block 3 is disposed between the lower support shell 1 and the upper closed shell 2, and the conductor 4 is disposed between the lower support shell 1 and the insulating filler block 3; the conductor 4 is wrapped with the insulator 5 on its outer side.

[0018] The lower support shell 1 includes a bottom shell 11, a stabilizing block 12, a mounting slot 13, a locking groove 14, and a connecting shell 15. The stabilizing block 12 is fixedly mounted on the bottom surface of the bottom shell 11, and the mounting slot 13 is opened inside the stabilizing block 12. The connecting shell 15 is located above the bottom shell 11, and the locking groove 14 is located between the bottom shell 11 and the connecting shell 15.

[0019] The upper enclosed shell 2 includes an enclosed shell 21, a connecting side plate 22, a gasket 23, and a connecting bolt 24. The connecting side plate 22 is fixedly installed on both sides of the enclosed shell 21. The enclosed shell 21 is engaged with the inner side of the engaging groove 14 above the lower support shell 1 by the connecting side plate 22. The gasket 23 is located on the outer side of the connecting side plate 22, and the connecting bolt 24 is engaged inside the connecting side plate 22, the connecting shell 15, and the insulating filler block 3.

[0020] The bottom shell 11, the engaging groove 14, and the connecting shell 15 inside the lower support shell 1 are connected as one piece and are all supported by aluminum alloy metal plates; the engaging groove 14 is an outward groove, and a connecting side plate 22 is installed inside it; the engaging groove 14 is an inward groove, and an insulating filler block 3 is installed inside it; the stabilizing block 12 and the insulating filler block 3 adopt a long strip mica base, and the inside of the stabilizing block 12 has a long strip groove to form an installation slot 13. The installation slot 13 and the groove inside the insulating filler block 3 together form several spaces to accommodate the conductor 4 and the insulator 5.

[0021] The upper closed shell 2 completely encloses the upper part of the lower support shell 1, and the connecting bolt 24 is made of several internal hexagonal socket bolts. After the connecting bolt 24 is removed outward, the upper closed shell 2 and the insulating filler block 3 can be pulled out or slid in from the lower support shell 1 in sequence.

[0022] The overall working principle of this busbar trunking housing is based on its modular structure and detachable design, achieving safe encapsulation, stable support, and convenient maintenance of the core conductor 4. The working process is as follows: First, the lower support shell 1 serves as the installation base. Its bottom shell 11 and stabilizing block 12 together provide the main structural support. The mounting slot 13 inside the stabilizing block 12 and the insulating filler block 3 together form the insulating space for placing the conductor 4 and its outer insulator 5. Then, the upper enclosed shell 2 begins to perform its core sealing and protection function. Its enclosed shell 21 is precisely engaged into the engaging groove 14 of the lower support shell 1 through the connecting side plates 22 on both sides, completing the initial positioning and mechanical closure. Finally, using connecting bolts 24 and washers 23, which sequentially engage and pass through the connecting side plates 22, connecting shell 15, and insulating filler block 3, the lower support shell 1 and the upper enclosed shell 2 are fastened into a complete, sealed, rigid protective shell, thereby ensuring the safe operation of the internal conductor 4 under the dual protection of the insulator 5 and the insulating filler block 3. When maintenance or replacement is required, the working principle of this design can be reversed: unscrew all the connecting bolts 24, and the upper closed shell 2, together with the insulating filler block 3, can be pulled out or slid out from the lower support shell 1, thereby fully exposing the conductor 4, realizing convenient maintenance operations.

[0023] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
