Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a conductive busbar mounting structure and a power distribution cabinet. Background Technology

[0002] The main functions of power buses include efficient power transmission, current distribution, and grounding protection. In power systems, power buses play a crucial role as key conductive components. They are typically made of high-purity aluminum alloys or copper, possessing excellent conductivity and mechanical properties, effectively conducting current, reducing power loss, and ensuring the efficiency and safety of power transmission.

[0003] Distribution cabinets typically contain multiple busbars. Before the cabinet leaves the factory, manufacturers usually instruct workers to install the busbars according to design requirements. Most commercially available busbars are secured with screws, with insulating components between the screws and the cabinet for insulation. In practice, the busbar placement often needs to be determined based on specific conditions, making this design inconvenient for workers to adjust during installation. Furthermore, tightening the screws may cause the insulating components to rotate, affecting assembly efficiency.

[0004] For example, Chinese patent application number CN202321713059.6 discloses a novel copper busbar connection structure for a high-voltage distribution cabinet, specifically stating that "a ceramic insulating column is fixedly connected to one side of the conductive busbar, a base is fixedly connected to one end of the ceramic insulating column, and support seats are fixedly welded to both sides of the base, with screws threaded into the interior of the support seats." This design, which uses screws to connect to a fixed block, is inconvenient for workers to adjust the installation position of the conductive busbar. Furthermore, tightening the screws may cause the insulating components to rotate, affecting the assembly efficiency of workers. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a conductive busbar installation structure that not only facilitates workers in adjusting the installation position but also in fixing the busbar, thereby overcoming the shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] This application provides a conductive bus mounting structure, including a first groove plate formed by bending a metal plate; a plurality of first mounting holes are provided on the wall of the first groove plate; the conductive bus is partially wrapped with insulating glue; a second mounting hole is provided on the conductive bus; an insulating member is provided between the conductive bus and the first groove plate; an anti-rotation part is formed on the outer wall of the insulating member; a first fastener passes through the first mounting hole and is fastened to the insulating member; a second fastener passes through the second mounting hole and is fastened to the insulating member.

[0012] Preferably, a nut is press-fitted onto the connecting end of the conductive busbar; a screw is inserted into the nut, and the screw fixes the wire to the conductive busbar.

[0013] This application provides a power distribution cabinet, including a conductor bar mounting structure, a mounting frame, a cabinet panel, and a cabinet frame. The cabinet panel is disposed on the cabinet frame. The mounting frame includes a second groove plate arranged horizontally and a third groove plate arranged vertically. The second groove plate is provided with a plurality of third mounting holes, and the third groove plate is provided with a plurality of fourth mounting holes. The second groove plate is fixed to the cabinet frame of the power distribution cabinet, and the third groove plate is fixed to the second groove plate.

Specifically, as can be seen from the above technical solution, the first groove plate is formed by bending a metal plate. This structure is lightweight, has good resistance to deformation, and is low in cost.

[0018] Insulating adhesive provides insulation protection for the conductive busbars, improving their insulation capacity at corresponding locations. Insulating components are used to separate the conductive busbars from the first channel plate, ensuring safety.

[0019] During assembly, the first slot plate is fixed inside the distribution cabinet; the first fastener passes through the first mounting hole to secure the first slot plate to the insulating component; the second fastener passes through the second mounting hole to secure the insulating component to the busbar.

Simultaneously, the outer wall of the insulating component has an anti-rotation part. During assembly, workers can use a wrench to fix it to the anti-rotation part before tightening the first and second fasteners. This design prevents the insulating component from rotating, thus improving assembly efficiency. Attached Figure Description

At the same time, the anti-rotation part 121 formed on the outer wall of the insulating part 120 can be activated during installation to prevent the insulating part 120 from rotating, thereby improving the assembly efficiency of workers.

[0033] This application provides a conductive busbar mounting structure 10, including a first groove plate 110 formed by bending a metal plate; a plurality of first mounting holes 114 are provided on the wall of the first groove plate 110; an insulating adhesive 132 is partially wrapped on the conductive busbar 130; a second mounting hole 131 is provided on the conductive busbar 130; an insulating member 120 is provided between the conductive busbar 130 and the first groove plate 110; an anti-rotation part 121 is formed on the outer wall of the insulating member 120; a first fastener 117 passes through the first mounting hole 114 and is fastened to the insulating member 120; a second fastener 134 passes through the second mounting hole 131 and is fastened to the insulating member 120.

The first mounting holes 114, the second mounting holes 131, and the third mounting holes 212 can be formed by drilling or punching. The conductive busbar 130 is a conductive copper busbar or a conductive aluminum busbar. Preferred assembly steps: 1. During assembly, the worker first fixes the first slot plate 110 to the mounting frame 210 with screws. 2.

The first insulating washer 118 can be a rubber or plastic washer with a certain degree of elasticity. Of course, the washer can also be a metal washer with an insulating material on its surface. Having two or more second mounting holes 131 allows the conductive busbar 130 to be installed more securely and with more even force distribution. In this embodiment, the first fastener 117 and the second fastener 134 are provided with an insulating coating, such as one of alumina, insulating plastic, polyimide film coating, or nickel-phosphorus Teflon coating.

[0037] Preferably, a nut 135 is press-fitted onto the connecting end of the conductive busbar 130; a screw is inserted into the nut 135, and the screw fixes the wire to the conductive busbar 130. A hole is drilled in the conductive busbar 130, and then the nut 135 is press-fitted onto the conductive busbar 130 using a machine. This design facilitates cable assembly by workers, as the screw can directly fix the wire core to the conductive busbar 130.
