Description

Technical Field

[0001] This utility model relates to the field of aluminum-clad copper technology, and in particular to a structurally stable aluminum-clad copper composite plate and strip. Background Technology

[0002] In the field of aluminum-clad copper transition, the right angle of the copper-aluminum composite edge is a sharp, notched structure, which is prone to stress concentration during processing, and the joint is prone to breakage, causing open circuit accidents.

[0003] The applicant's earlier application (publication number CN220791692U) discloses an aluminum-clad copper composite strip, which improves the composite strength and structural stability of the aluminum-clad copper composite strip by providing a first inclined surface on the side of the groove and a second inclined surface on the side of the copper strip, and combining the first and second inclined surfaces together to form an inclined transition structure.

[0004] However, the transition between the inclined surface and the bottom surface is a sharp angle. This sharp angle area is prone to stress concentration and fracture during processing. The sharp angle part is poorly composited, and there is still room for improvement in structural stability.

[0005] Therefore, there is an urgent need for an aluminum-clad copper composite plate and strip that can further improve structural stability. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a structurally stable aluminum-clad copper composite plate and strip.

[0008] As a further improvement to the above technical solution, the arc transition surface is also provided at the intersection of the top surface of the copper strip and the composite side surface.

[0009] As a further improvement to the above technical solution, the longitudinal section of the copper strip is rectangular, and the shape of the groove is adapted to the copper strip.

[0010] As a further improvement to the above technical solution, the thickness of the copper strip is 0.4-5.0 mm, the width of the copper strip is 8-60 mm, and the radius of the arc transition surface is 0.2-3 mm.

[0011] As a further improvement to the above technical solution, a first arc transition surface is provided at the intersection of the side surface and the bottom surface of the groove, and a second arc transition surface is provided at the intersection of the side surface and the bottom surface of the copper strip. The first arc transition surface and the second arc transition surface cooperate to form the arc transition surface.

[0012] As a further improvement to the above technical solution, the number of grooves is 1-20, and the number of copper strips corresponds to the number of grooves.

[0013] As a further improvement to the above technical solution, the width of the aluminum strip is 500-2000mm and the thickness of the aluminum strip is 2.0-15mm.
