[0002] Energy storage connectors are connectors used in energy storage systems to connect energy storage devices, battery packs, inverters and other related equipment. Energy storage connectors usually need to have high current, low resistance, reliability and safety to meet the requirements of high-power energy storage systems. They usually adopt high-current plug and socket designs to ensure efficient power transmission and connection stability.

[0003] In order to ensure the high transmission efficiency of the energy storage connector, the existing connector socket part will use a copper busbar with silver plating on the surface to connect to the equipment. Although it has achieved a high level of conductivity and transmission efficiency, the waterproof level needs to be improved because the connector is sealed with an ordinary sealing ring. Secondly, the female terminal part of the existing connector plug is connected by welding during production, which will increase the contact resistance to a certain extent when overcurrent occurs. Therefore, the utility model proposes a copper busbar energy storage connector. Utility Model Content

[0024] like Figure 1-Figure 2 As shown, the male terminal assembly 5 includes a copper busbar 51 that passes through the side wall of the socket 1 and is fixedly connected to the socket 1. One end of the copper busbar 51 located in the socket 1 is fixedly connected to a copper plate 52, and the other side of the copper plate 52 is fixedly connected to a conductive column 53. The female terminal assembly 3 includes a round tube 31 fixed inside the plug 2 and a conductive plate 32 fixed inside the extension part, and the conductive column 53 is inserted into the inside of the round tube 31.

[0025] When the plug 2 is inserted into the socket 1 , the conductive post 53 is inserted into the round tube 31 .

[0026] like Figure 3 As shown, the conductive plate 32 is integrally formed with the round tube 31. By designing the integrally formed structure, the contact resistance can be reduced, and the female terminal assembly 3 is also made of copper with silver plating on the surface.
