The shell has excellent high and low temperature resistance, and can maintain stable structural and insulating performance in the working temperature range of -40℃ to +85℃, adapting to the harsh outdoor and indoor working environments of energy storage equipment such as outdoor photovoltaic energy storage, factory commercial energy storage, and household balcony energy storage. In terms of connection structure, the plug adopts a foolproof anti-reverse insertion design, with unique groove and card position structure. It can only be inserted in the specified direction during assembly, which completely avoids equipment damage and circuit short circuit accidents caused by reverse insertion of positive and negative poles. At the same time, it is equipped with a self-locking buckle structure. After the plug is fully inserted, the buckle automatically locks the connection state, which can effectively prevent the plug from loosening and falling off caused by equipment vibration, line pulling, and environmental vibration during the operation of the energy storage system. The locking force is scientifically designed, which not only ensures the firmness of the connection, but also avoids the difficulty of disassembly and maintenance caused by excessive locking tightness, balancing the stability of use and the convenience of later maintenance.

It can work stably in humid environments such as coastal areas, rainy seasons, and indoor damp environments for a long time, and is not prone to electric leakage, short circuit, and conductive failure. The internal sealing structure adopts high-quality silicone rubber sealing ring, which has excellent aging resistance and compression resistance, and will not deform or fail after long-term compression and high and low temperature cycle changes, maintaining lasting sealing performance. In terms of mechanical life, the plug has passed more than 10,000 times of plugging and unplugging tests. After repeated plugging and unplugging, the terminal contact performance and shell structure remain intact, without poor contact, loose plugging, and shell cracking, fully meeting the frequent assembly, debugging, and maintenance needs of energy storage equipment in the whole life cycle. In addition, the product has excellent vibration resistance and impact resistance. It can resist continuous vibration generated by the operation of energy storage inverters and slight impact during equipment transportation and installation, without internal terminal displacement and structural loosening, ensuring the long-term reliable operation of the energy storage system.
