[0002] An energy storage connector is a connector specifically designed for connecting and transmitting electrical energy. Its main functions are to provide current transmission, voltage distribution, and partial protection for the system's battery pack. It needs to withstand high voltage and high current while maintaining sufficiently low contact resistance to ensure stable current transmission, low energy consumption, and improve the overall efficiency of the energy storage system.
[0003] With the popularization of electric vehicles, many new energy vehicles need to be charged every day, so charging plugs are frequently used. However, the charging plugs are often used outdoors. The pins of traditional charging plugs are prone to loosening because the pins are assembled separately. Over time, they are easy to loosen, and the waterproof effect is not good. Assembly is also cumbersome, time-consuming, labor-intensive, and costly. Utility Model Content
