The battery lead of existing portable type electronic product is nickel down-lead basically, and the conductance of nickel is not high in fact, but the reason that can generally use is that its weld strength and stability can reach requirement, and conductance surpasses iron or stainless steel etc. after all.And the words of considering from conductance, copper or silver are optimal selections, but the weld strength of copper or silver and stability are low, cause battery because the failure rate of weld strength and stable aspect is too high and can't satisfy instructions for use, and the ratio of copper or silver is great, is unfavorable for the lightweight of battery.
Prior art proposes with the next lead-in wire as this class battery of aluminum or aluminum alloy, although the light specific gravity of aluminum or aluminum alloy can adapt to light-weighted requirement, and the conductance of aluminium is also high than nickel, should be good selection, still, aluminum or aluminum alloy also exists weld strength and the low problem of stability.Prior art proposes using the aluminum or aluminum alloy lead-in wire to improve, its main technical schemes is to come as connector at the metal that the one or both ends of aluminum or aluminum alloy lead-in wire arrange except aluminum or aluminum alloy, come to connect and accept soldering with other parts by connector, can improve pad intensity and welding stability like this, the metal or alloy except aluminum or aluminum alloy of its selection mainly is nickel, iron and stainless steel.This improvement technology can realize reducing the weight of battery lead, but there is serious defective in this technology, this defective is exactly because the metallic conductivity of connector is lower than aluminum or aluminum alloy, therefore can affect the discharge of battery and under the long electric power thus supplied of battery, have a large amount of heat generations, can affect the life-span of battery or even electronic product.
Summary of the invention
The purpose of this invention is to provide a kind of technical scheme, described technical scheme is in the improvement project of using on aluminum or aluminum alloy lead-in wire and the connector technical scheme, this technical scheme can solve the light-weighted a large amount of generations that reduce simultaneously the battery heat of battery, has really realized substituting existing nickel down-lead by aluminium name aluminium alloy lead-in wire.
The present invention is achieved by the following technical solutions:
A kind of battery lead of portable phone includes lead-in wire main body that aluminum or aluminum alloy makes and is provided with the connector that connects for other parts with the go between one or both ends of main body of being connected; On the surface of connector or be to adopt with other parts and with the face that is connected of lead-in wire to mix copper and process at least, the described thickness of mixing the copper layer is the 5-200 nanometer, and mixing the copper amount is every square centimeter of 25-80 milligram.
Described connector is iron or stainless steel.
More preferably, the described thickness of mixing the copper layer is the 15-40 nanometer, and mixing the copper amount is every square centimeter of 40-75 milligram.
Described phone lead-in wire and connector are banded.
The beneficial effect that the present invention compares with prior art is:
Result after employing is mixed copper and processed is the conductance that has increased connector, and because the raising of conductance and uses iron or stainless steel has improved intensity as connector can reduce thickness and the width of connector, has effectively reduced the weight that goes between.
