[0002] Energy storage systems are increasingly widely used in the new energy field. As a key connection component within the system, the single-core connector plays a crucial role in connecting battery modules with inverters, power management systems, or other energy storage modules. Traditional connector designs are typically multi-core, which, while suitable for various scenarios, is prone to accidental disconnection from the socket due to vibration, external forces, or other factors, affecting the stability of the energy storage system, especially for single-core applications requiring high current transmission. In industrial environments, energy storage devices often face adverse conditions such as humidity and dust, where traditional connectors struggle to provide sufficient sealing protection, potentially leading to equipment damage or short-circuit risks. Furthermore, due to the limitations of the connector and socket structure, traditional designs require high precision during installation and operation, resulting in poor flexibility and reduced efficiency. Therefore, designing a single-core connector for energy storage with high reliability, excellent sealing, and adaptability to industrial environments is crucial for improving the operational safety and stability of energy storage systems.
