Description

Technical Field

[0001] This utility model relates to the field of copper-aluminum busbar technology, and in particular to an anti-detachment copper-aluminum busbar. Background Technology

[0002] Copper and aluminum busbars are widely used in transformers, metallurgy, and construction industries. They are used as conductor connection components. Existing copper and aluminum busbar products have a flat structure. During installation, they are fitted to the mating position with a flat surface. When the mating position is tightened with conductor cables and other products, the surrounding area is prone to lifting, resulting in relatively poor tightness of the installation position. This can easily lead to technical problems such as poor contact and poor tensile strength during use, requiring regular maintenance. Utility Model Content

[0003] The purpose of this utility model is to provide an anti-detachment copper-aluminum busbar. During use, the two arc-shaped structures on the main structure, when combined with the installation position, allow for a larger area of ​​contact with auxiliary products such as conductor cables. This ensures that the surrounding area has an anti-lifting effect during tightening, resulting in higher connection strength and tighter fit. This effectively reduces the likelihood of poor contact during use, strengthens the combined force at the connection points, increases tensile strength, and improves safety and reliability. It also effectively reduces the frequency of regular maintenance, thereby lowering maintenance costs and improving overall durability.

[0004] The technical solution of this utility model is as follows:

[0005] A type of anti-detachment copper-aluminum busbar, characterized in that: it includes a first main body mating plate, and an integrally formed second fastening combination plate is provided on the left side of the first main body mating plate. The upper and lower sides of the first main body mating plate and the second fastening combination plate are on cylindrical surfaces of the same diameter. The projection of the second fastening combination plate in the vertical direction is a fan-shaped structure. The lower end of the first main body mating plate is an arc-shaped mounting and mating connection groove with an opening facing downwards. The lower end of the second fastening combination plate is provided with an inverted conical positioning and reinforcing separation column on the left side. The upper end of the second fastening combination plate is provided with fastening connection mating holes that are evenly distributed front and back and penetrate the lower end of the entire structure. The upper end of the first main body mating plate is provided with spare transition mating holes that penetrate the lower end of the entire structure and are evenly distributed left and right. The upper and lower sides of the fastening connection mating holes and the spare transition mating holes are the unwrapped aluminum busbar body.

[0006] Furthermore, the width of the right side of the second fastening assembly plate in the front-back direction is the same as the width of the first main body mating plate in the front-back direction.

[0007] Furthermore, the first main body mating plate and the second fastening assembly plate have the same wall thickness.

[0008] Furthermore, the upper and lower edges of the first main body mating plate and the second fastening combination plate are respectively provided with safety mating rounded corner structures.

[0009] Furthermore, the fastening connection mating hole is located at the center of the left-right length of the second fastening assembly plate.

[0010] The beneficial effects of this utility model are:

[0011] This utility model, through the two arc-shaped structures on the main structure, allows for a larger contact area with auxiliary products such as conductor cables when they mate with the installation position. It also ensures an anti-lifting fit when tightened, resulting in higher connection strength and tighter fit. This effectively reduces the likelihood of poor contact during use. The stronger combined force at the mating points also leads to higher tensile strength and more reliable safety. Furthermore, it effectively reduces the frequency of regular maintenance, thereby lowering maintenance costs and improving overall durability. Attached Figure Description

[0020] like Figures 1 to 7As shown, an anti-detachment copper-aluminum busbar includes a first main mating plate 1. A second, integrally formed fastening combination plate 2 is provided on the left side of the first main mating plate 1, forming the main body of the copper-aluminum busbar product. The upper and lower sides of both the first main mating plate 1 and the second fastening combination plate 2 are on cylindrical surfaces of the same diameter. The projection of the second fastening combination plate 2 in the vertical direction is a fan-shaped structure, making the width on the left side greater than the size on the right side, resulting in stronger fastening at the middle position during mating. The mating force on the left side is also higher. The lower end of the first main mating plate 1 is an arc-shaped mounting groove with an opening facing downwards. This position serves as the contact surface for connection during installation. During mating, this position can be pressed against components such as conductor cables, or directly and tightly fitted to column-like mating structures, ensuring a larger contact area during mating. This structure also increases the strength of the structure, enhances the load-bearing capacity during use, and provides a reliable anti-lifting effect at the outer edge. The second fastening assembly plate 2 has an inverted conical positioning and reinforcing separation column 3 on its lower left side. This column serves as a positioning structure during installation, improving efficiency. It can also be used as a separation structure when connecting multiple cables below, enhancing cable stability and providing better separation assistance. The upper end of the second fastening assembly plate 2 has evenly distributed fastening connection holes 4 that penetrate the lower part of the plate, serving as connection holes for fastening. The upper end of the first main body mounting plate 1 has spare adapter holes 5 that penetrate the lower part of the plate and are evenly distributed left and right. These holes can be used as auxiliary fastening holes or as output positions for conductor cable products, offering greater flexibility and expanding the product's application range. The upper and lower sides of the fastening connection holes 4 and the spare adapter holes 5 are covered by an unencased aluminum busbar, while other areas are constructed of conventional copper. When in use, the two arc-shaped structures on its main structure, when combined with the installation position, allow for a larger area of ​​contact with auxiliary products such as conductor cables. This ensures that the surrounding area has an anti-lifting effect when tightened, resulting in higher joint strength and tighter fit. This effectively reduces the occurrence of poor contact during use, strengthens the combined force of the mating parts, increases tensile strength, and enhances safety and reliability. It also effectively reduces the frequency of regular maintenance, thereby lowering maintenance costs and improving overall durability.

[0021] Preferably, the width of the right side of the second fastening combination plate 2 in the front-back direction is the same as the width of the first main body mating plate 1 in the front-back direction, which makes the overall structural support strength better, the service life during use longer, the flatness of the connection position better, and the production and processing more convenient, resulting in higher overall production and processing efficiency.

[0022] Preferably, the first main body mating plate 1 and the second fastening combination plate 2 have the same wall thickness, which can further improve the overall structural stability and make the mating load-bearing strength more reliable during use.

[0023] Preferably, the upper and lower edges of the first main body mating plate 1 and the second fastening combination plate 2 are respectively provided with safe mating rounded corner structures, which can avoid the presence of sharp corner structures during installation and make the connection safety during mating better.

[0024] Preferably, the fastening connection mating hole 4 is located at the center of the left-right length of the second fastening combination plate 2, which results in stronger combined load-bearing capacity and further improved safety during mating.

[0025] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements or substitutions can be made without departing from the principle of this utility model, and these improvements or substitutions should also be considered within the protection scope of this utility model.
