Copper-Aluminium connecting terminal

There is one kind of cupreous and aluminous connecting terminal for electricity transmission, including an aluminous body of which one end like a tube and another like a board. There are layers of sheet coppers at one side surface of the board of body and the sheet copper layer is close fittingly joined to an no filler metal structure, with relative board surface. This practical new type incorporates sheet copper layers at the aluminous body, which is well connected and will not fall off. The entire body is of high strength and will not crack with collision. The no filler metal structure reduces the electric resistance of conductor and the current loss. It raises power transmission efficiency and transformation pressure resistance. Meanwhile few sheet coppers are needed. This reduces the copper product consumption and lowers the costs.
