Abstract

The invention discloses a tinned copper alloy conductor production process and a tinned structure, and relates to the technical field of conductors, the tinned copper alloy conductor production process specifically comprises the following steps: step 1, removing surface oxides of a copper-aluminum-rare earth alloy blank by a polisher to obtain a copper-aluminum-rare earth alloy ingot; secondly, the aluminum alloy cast ingot is stretched through a water tank type drawing machine, drawing oil is sprayed synchronously during stretching, the drawing speed is 400 m / min, a bus is obtained, and the diameter of the bus is 2.05 mm; 3, a wire drawing machine carries out wire drawing treatment on the bus to obtain a wire rod, and the wire diameter of the wire rod is 0.8 mm; through the mode, the copper-aluminum rare earth alloy is replaced by the copper alloy wire, under the corrosion resistance of the copper element in the copper-aluminum rare earth alloy and the synergistic effect of the copper element and the aluminum element, the conductivity is not reduced while the surface oxidation resistance is improved, the weldability and the signal transmission of the wire are ensured, and meanwhile, the copper alloy wire has the advantages of being simple in structure and low in cost. And the soft wire can be conveniently mounted in the tinning structure during tinning.

Description

technical field [0001] The invention relates to the technical field of conductors, in particular to a tinned copper alloy conductor production process and a tinned structure. Background technique [0002] At present, the copper braided wires used in the market are generally TR-type annealed copper wires. This kind of copper braided wires uses a large amount of copper wires for braided wires for shielding. Although it has a good shielding effect, it consumes a lot of copper materials. Production costs are high. [0003] In order to reduce costs, tinned copper conductors are now used instead of copper wires. However, the existing tin-plated copper conductors have relatively poor performances such as high temperature resistance and corrosion resistance, and will cause economic losses to enterprises during use. Moreover, the existing tinned copper composite conductor is easy to oxidize, which affects the solderability and signal transmission of the wire, and it is inconvenient...
