[0002] The same applicant of the present application previously disclosed a copper-aluminum composite transition plate (publication number: CN206461114U), which includes an aluminum end for connecting to an aluminum material and a copper-aluminum composite end for connecting to a copper material. The copper-aluminum composite end includes an aluminum layer and an upper copper composite layer and a lower copper composite layer respectively composited on the upper and lower sides of the aluminum layer. The ends of the upper copper composite layer and the lower copper composite layer close to the aluminum end are staggered along the length direction of the copper-aluminum composite transition plate, and the staggered interval of the upper copper composite layer and the lower copper composite layer in the length direction of the copper-aluminum composite transition plate is 3 to 15 mm.

[0003] However, in actual application, since it is necessary to avoid complex joints during bending, the staggered interval of the above technology is 3 to 15 mm, which is a large range and is not conducive to client design and has weak adaptability. Utility Model Content

[0004] In order to solve the above technical problems, the purpose of the present invention is to provide a copper-aluminum composite transition plate with strong adaptability.

[0005] The technical solution adopted by the utility model to solve the problem is: a copper-aluminum composite transition plate, including an aluminum end and a copper-aluminum composite end connected together on the left and right, the copper-aluminum composite end including an upper copper clad layer and a lower copper clad layer, the left end portions of the upper copper clad layer and the lower copper clad layer are staggered along the left and right directions to form a staggered interval, characterized in that: the staggered interval is 4-10 mm.

[0006] As a further improvement of the above technical solution, a connecting surface is provided between the left end portions of the upper copper clad layer and the lower copper clad layer and the aluminum end, and the connecting surface is a curved surface.

[0007] As a further improvement of the above technical solution, the copper-aluminum composite end comprises an upper copper clad layer, an aluminum layer and a lower copper clad layer from top to bottom, and the aluminum end and the aluminum layer are both made of 8030 aluminum raw material.

[0008] The beneficial effects of the present invention are as follows: the present invention reduces the length range of the staggered interval to 4-10 mm, reduces the size of the bending part, facilitates the client design, and improves the adaptability of the transition plate.
