Description

Technical Field

[0001] This utility model relates to the field of strip technology, specifically to a steel-copper-clad composite strip. Background Technology

[0002] Metal composite sheets and strips refer to sheets and strips with one metal layer laminated onto another, achieving resource conservation and cost reduction without compromising performance (corrosion resistance, mechanical strength, etc.). Metal composite material technology leverages the advantages of each component material, achieving optimal resource allocation, conserving precious metals, and fulfilling performance requirements that a single metal cannot meet. Its main applications include corrosion protection, pressure vessel manufacturing, power plant construction, petrochemicals, pharmaceuticals, light industry, and the automotive industry.

[0003] Traditional steel-clad copper composite boards simply bond steel and copper layers together, resulting in a weak bond between them. Under external forces, especially dynamic loads and complex stresses, such as electromagnetic forces generated by current changes during the operation of electrical equipment, or vibrations and impacts experienced by mechanical parts, delamination is very likely to occur between the steel and copper layers. This not only leads to a significant decrease in material performance but also seriously affects the quality and reliability of related products, increasing maintenance costs and replacement frequency.

[0004] Based on the above, this utility model proposes a steel-copper-clad composite strip, which can effectively solve the above problems. Utility Model Content

[0008] According to the above technical solution, as a further preferred technical solution, the copper layer is provided with a plurality of reinforcing ribs evenly distributed at equal intervals along the width direction.

[0009] According to the above technical solution, as a further preferred technical solution, the outer surface of the copper layer is provided with anti-slip texture, which is serrated or wavy.

[0010] According to the above technical solution, as a further preferred technical solution, the cross-sectional shape of the first rib and the second rib is an isosceles trapezoid or an isosceles triangle.

[0011] According to the above technical solution, as a further preferred technical solution, the cross-sectional shape of the reinforcing rib is circular or rectangular.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0013] This utility model provides a steel-copper clad composite strip, which fully utilizes the high strength of steel and the good conductivity and corrosion resistance of copper through a steel-copper clad composite structure. In the connection structure, the first rib of the steel layer and the second rib of the copper layer are tightly fitted, increasing the contact area and interlocking force between them, thus enhancing the connection strength and stability between the steel and copper layers. Simultaneously, by setting positioning holes and positioning posts, the relative displacement between the steel and copper layers is limited, increasing the positioning accuracy when the steel and copper layers are combined.

However, it should be understood that the accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. For better illustration of this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0017] A steel-copper clad composite strip includes a steel layer 1 and a copper layer 2 compositely connected to both sides of the steel layer 1; the two sides of the steel layer 1 are respectively provided with a plurality of first ribs 11 distributed at equal intervals along the width direction, and the inner surface of the copper layer 2 is provided with a plurality of second ribs 21 distributed at equal intervals along the width direction, the first ribs 11 and the second ribs 21 are spaced apart, and the outer surface of the first ribs 11 is in close contact with the second ribs 21; the two sides of the steel layer 1 are respectively provided with positioning holes 12 distributed at equal intervals along the opposite direction of the length, and the inner surface of the copper layer 2 is provided with positioning posts 22 that are connected to the positioning holes 12.

[0018] This invention employs a steel-copper composite structure, fully utilizing the high strength of steel and the excellent electrical conductivity and corrosion resistance of copper. In the connection structure, the first rib 11 of the steel layer 1 and the second rib 21 of the copper layer 2 are tightly fitted together, increasing the contact area and interlocking force between them, thus enhancing the connection strength and stability between the steel layer 1 and the copper layer 2. Simultaneously, by providing positioning holes 12 and positioning posts 22, the relative displacement between the steel layer 1 and the copper layer 2 is limited, increasing the positioning accuracy when the steel layer 1 and copper layer 2 are combined.

[0019] Furthermore, in another embodiment, the interior of the copper layer 2 is provided with a plurality of equally spaced reinforcing ribs 23 along the width direction, and the cross-sectional shape of the reinforcing ribs 23 is circular or rectangular.

[0020] By setting reinforcing ribs 23, the structural strength of the copper layer is improved, thereby enhancing the strength and load-bearing capacity of the entire steel copper-clad composite strip, enabling it to withstand greater external forces, broadening the product's application range, and making it suitable for occasions with high strength requirements.

[0021] Furthermore, in another embodiment, the outer surface of the copper layer 2 is provided with anti-slip texture 24, which is serrated or wavy.

[0022] By setting anti-slip texture 21, the friction of the outer surface of the copper layer is increased, making it less likely for objects to slip on the surface of the copper layer when using the composite strip, thus improving safety and stability during use.

[0023] Furthermore, in another embodiment, the cross-sectional shape of the first rib 11 and the second rib 21 is an isosceles trapezoid or an isosceles triangle.

[0024] By setting the first rib 11 and the second rib 21 in the shape of an isosceles trapezoid or an isosceles triangle, a tighter fit and interlocking force is formed between the first rib 11 and the second rib 21, which further enhances the firmness of the composite connection between the steel layer 1 and the copper layer 2 and improves the structural stability of the composite strip.
