Embodiment 1

[0036] The original product design is a straight strip-shaped pure nickel conductive connecting piece with a thickness of 0.4mm, a width of 4mm, a total length of 50mm, and a hardness state of 1 / 4.

[0037] See figure 1 , using nickel / copper / nickel side composite metal structure. This section of nickel conductive connecting piece has a copper strip conductor 2, and the two ends of the copper strip conductor 2 in the length direction are symmetrically and firmly combined with nickel welding parts 1, 3, copper strip conductor 2 and nickel. A bonding surface 12 that is tightly bonded is formed between the welding parts 1, another bonding surface 23 that is tightly bonded is formed between the copper strip conductor 2 and the nickel soldering part 3, the cross section of the copper strip conductor 2, The cross sections of the nickel welding parts 1 and 3 are both rectangular. Wherein, the material structure of the bonding surface 12, 23 is dense. The thickness and width of the ...

Abstract

A conductive connecting sheet with a side composite metal structure comprises at least two foreign metal sheets. Each metal sheet comprises at least one copper metal sheet or nickel metal sheet, and the rest is a metal sheet at the price lower than the price of copper and nickel. Each metal sheet is arranged along the length direction of the conductive connecting sheet. The adjacent metal sheets are combined closely on an end face, and lap joint does not exist among the adjacent metal sheets. The production method comprises the following steps that: in the at least two metal strips, the adjacent metal strips are firmly combined on the adjacent side to form a side composite board strip by side composite technology; and the produced board strip is subjected to rolling and process annealing treatment to produce a final board strip with thickness the same as that of the conductive connecting sheet, and then is punched and formed along the transverse direction. The invention makes the bestof the advantages of combination of the side composite metal board strips, can ideally meet the requirement of the overall high-conductivity and the transition welding component, prevent the negativeeffect of the traditional lap joint and obviously save scarce metal and improve the waste recovery value.

Description

technical field [0001] The patent of the present invention relates to a conductive connecting sheet with a side composite metal structure and its production method. The conductive connecting sheet is mainly used in the fields of electronics, electrical appliances, batteries, electric vehicles and the like. Background technique [0002] At present, a large number of conductive connectors are used in the fields of electronics, electrical appliances, batteries, and electric vehicles. The materials of the paired and connected parts mainly include steel, nickel, aluminum, copper, stainless steel, etc. The materials of the conductive connectors themselves are all metal, especially Most of them are nickel and copper. Although copper has the characteristics of good electrical and thermal conductivity, good mechanical properties, and certain corrosion resistance, it often encounters welding difficulties or The problem of poor welding quality; and although nickel has good comprehensi...
