Description

Technical Field

[0001] This utility model relates to the field of electrical cabinet technology, and more specifically, to a flexible copper busbar structure for electrical cabinets. Background Technology

[0002] An electrical cabinet is a cabinet structure used for the centralized installation and protection of electrical equipment and components. It houses various electrical equipment and components in one cabinet, facilitating centralized control and operation of power systems or electrical equipment, such as controlling the starting, stopping, and speed regulation of motors, as well as controlling the on / off state of various circuits, thus offering the advantages of centralized control.

[0003] Currently, electrical cabinets are equipped with copper busbar structures. These copper busbars serve as connecting conductors between various electrical components within the cabinet, undertaking the important task of transmitting current and enabling power to be transferred between components to achieve the normal operation of electrical equipment.

[0004] However, the commonly used copper busbar structure is rigid copper busbar. But the installation space inside the electrical cabinet is complex, and rigid copper busbar has poor flexibility and is not easy to bend and deform. In order to adapt to the complex spatial layout inside the electrical cabinet, frequent bending operations are required during the installation process, which increases the installation cost and difficulty. A flexible copper busbar structure for electrical cabinets is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a flexible copper busbar structure for electrical cabinets.

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

[0007] A flexible copper busbar structure for an electrical cabinet includes a first upper nickel sheet, a first lower nickel sheet below the first upper nickel sheet, and an upper copper busbar layer located between the first upper nickel sheet and the first lower nickel sheet.

[0008] A second upper nickel sheet is disposed below the first lower nickel sheet, and a second lower nickel sheet is disposed below the second upper nickel sheet. A lower copper busbar is disposed at the middle position between the second upper nickel sheet and the second lower nickel sheet.

[0009] The present invention is further configured such that: the first upper nickel sheet, the upper copper busbar layer, and the first lower nickel sheet are combined to form the upper copper busbar, and the upper copper busbar is provided with a first through hole.

[0010] The present invention is further configured such that: the second lower nickel sheet, the second upper nickel sheet, and the lower copper busbar are combined to form a lower copper busbar, and the lower copper busbar is provided with a third through hole.

[0011] The present invention is further configured such that: the upper copper busbar and the lower copper busbar are combined to form a copper busbar body, the copper busbar body is provided with a second through hole, the end of the copper busbar body away from the first through hole is provided with a chamfer, and the end of the lower copper busbar away from the second through hole is provided with a chamfer.

[0012] By adopting the above technical solution, the end of the copper busbar away from the first through hole is chamfered, and the end of the lower copper busbar away from the second through hole is chamfered. By setting the chamfer, the copper busbar is easier to fit with other connecting parts, improving the convenience and accuracy of installation, and ensuring the tightness and reliability of the connection. By setting the second upper nickel plate, the first through hole, and the second through hole, a wire passage can be provided for the wires or other connecting parts, which facilitates the layout and wiring of electrical connections, making the structure of the entire electrical system more compact and neat, and easier to maintain and repair. The copper busbar can be divided into upper copper busbar and lower copper busbar, which allows for more flexible layout and operation during installation.

[0013] The present invention is further configured such that: the first upper nickel sheet is disposed on the upper layer of the copper busbar, and the second lower nickel sheet is disposed on the lower layer of the copper busbar.

[0014] The present invention is further configured such that: the lower copper busbar layer and the upper copper busbar layer are located in the middle position of the copper busbar body, and both the lower copper busbar layer and the upper copper busbar layer are composed of multiple layers of soft copper foil.

[0015] By adopting the above technical solution, since the lower and upper copper busbars are composed of soft copper foil, the lower and upper copper busbars have good bendability and flexibility, which can easily adapt to various complex spatial shapes and layout requirements. They can be bent and twisted at any angle according to actual needs, which greatly improves the flexibility of installation and is suitable for electrical equipment with compact space and complex wiring.

[0016] The present invention is further configured such that: the length of the first lower nickel sheet is less than the length of the first upper nickel sheet, and the length of the second upper nickel sheet is less than the length of the second lower nickel sheet.

[0017] By adopting the above technical solution, and by setting nickel strips of different lengths to adapt to the complex layout of the electrical system, different nickel strips can be set according to the installation method and the location of the fixing point of the copper busbar to better match the installation structure, making the copper busbar more stable after installation and reducing loosening or displacement caused by vibration or other external forces.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. By setting the lower and upper copper busbar layers to be composed of soft copper foil, the lower and upper copper busbar layers have good bendability and flexibility, and can be bent and twisted at any angle according to actual needs, which greatly improves the flexibility of installation and is suitable for electrical equipment with compact space and complex wiring.

[0020] 2. By setting chamfers, the copper busbars can be more easily matched with other connecting parts, improving the convenience and accuracy of installation and ensuring the tightness and reliability of the connection.

[0021] 3. By setting a second upper nickel sheet, a first through hole, and a second through hole, a wire passage can be provided for wires or other connecting components, which facilitates the layout and wiring of electrical connections, making the structure of the entire electrical system more compact and neat, and easier to maintain and repair.
