Description

Technical Field

[0001] The utility model relates to the technical field of electric power facilities, in particular to a variable flexible anti-corrosion special-shaped nano copper connector. Background Art

[0002] Power battery is a kind of energy storage device that can be charged and discharged, and it is also a mobile power source. It is widely used in electric vehicles. In order to meet the power requirements of voltage and current, power battery modules are usually connected in series or in parallel, and the maximum current can reach hundreds of amperes. At present, the connection of power battery modules is generally connected by copper busbars or copper cables. The defect of the copper cable connection structure is that when the copper cable is crimped inside the wiring sleeve, there is insufficient contact surface between the copper wire and the wiring sleeve, or even only a small amount of copper wire is pressed, resulting in excessive contact resistance between the wiring sleeve and the copper wire, which is prone to failure during high current charging and discharging. Although the copper busbar has a large contact surface, strong conductivity, high current bearing, small resistance value, and durability, the current copper busbar is usually set in an integrated manner, which leads to the need to replace the entire copper busbar when it is damaged, which will increase the cost investment to a certain extent. In addition, it will also cause the length used to be relatively fixed, which has limitations. Therefore, a variable flexible anti-corrosion special-shaped nano copper connector is invented.
