The wiring assembly 3 is provided in the wiring cavity 12, and the electrical connection element 2 is provided in the plug-in sleeve 13; the molded case 1 is located in the plug-in cavity 11. A locking bin 14 is provided on one side, and the locking assembly 4 includes a slider 41, a lock catch 42, a spring 43 and a baffle 44. The slider 41 is slidably provided in the locking bin 14, one end of the lock catch 42 is connected to the slider 41, and the other end extends to the plug-in cavity 11. The baffle 44 is provided at one end of the locking bin 14, and the two ends of the spring 43 respectively abut the slider 41 and the baffle 44; a socket 141 is provided at one end of the locking bin 14 for inserting a pin to push the slider 41 to slide in the locking bin 14. The present invention adopts a plastic shell 1 structural design, which not only ensures the overall lightweight and cost-effectiveness of the connector, but also effectively isolates the plug-in and wiring areas through the finely divided plug-in cavity 11 and wiring cavity 12 inside it, avoids electrical interference, and improves electrical performance. The provision of the plug sleeve 13 makes the plug-in process smoother, reduces the risk of wear and poor contact. The locking assembly 4 realizes reliable locking and unlocking of the connector plug-in state through the coordinated action of the slider 41, the lock 42, the spring 43 and the baffle 44. When the connector is correctly plugged in, the lock 42 automatically engages to ensure a firm connection; when unlocking is required, the slider 41 is pushed by inserting the external ejector pin into the socket 141 to easily unlock the connector, which is simple and quick to operate. The addition of the spring 43 not only provides a reset force for the lock 42, but also enhances the stability and durability of the lock. A socket 141 is provided at one end of the locking chamber 14 of the utility model for inserting the ejector pin to push the slider 41 to slide in the locking chamber 14. Special tools are required to unlock and ensure the safety of the plug-in. The socket 141 is specially designed for unlocking tools. Through precise insertion, it can effectively push the internal slider 41 to slide smoothly in the locking chamber 14, thereby realizing rapid locking and unlocking of the connector.

[0026] The wall of the plug-in cavity 11 is provided with a plug-in orientation strip 111. There are two plug-in orientation strips 111, which are arranged on both sides of the plug-in cavity 11. In this embodiment, the connector is ensured to be accurately aligned along the predetermined trajectory during the insertion process, effectively preventing damage or poor contact caused by misaligned insertion. At the same time, the plug-in orientation strip 111 acts as a physical guide, simplifying the operator's installation steps, reducing the requirements for operating skills, and improving work efficiency and installation success rate. In addition, this design also enhances the structural stability of the connector, and can still maintain reliable electrical connection and mechanical strength under long-term use or in harsh environments.

[0027] One end of the plug-in sleeve 13 extends out of the plug-in cavity 11, and a sealing groove 131 is provided at the end of the plug-in sleeve 13, and a plug-in sealing ring 132 is provided on the sealing groove 131. In this embodiment, the sealing groove 131 at the end of the plug-in sleeve 13 and the matching plug-in sealing ring 132 constitute a high-efficiency sealing system, which effectively prevents harmful substances such as dust and moisture in the external environment from invading the interior of the connector, protects the precision components and circuits inside the connector, and extends the service life of the product. The combination of the sealing groove 131 and the plug-in sealing ring 132 also enhances the sealing performance of the connector during the plug-in and unplugging process, reduces the risk of sealing failure caused by the plug-in and unplugging action, and ensures reliable connection and stable transmission of the connector in high-intensity or frequent use scenarios.

[0028] The power connection element 2 includes a power connection sleeve 21, a wiring sleeve 22, and a plug-in positioning post 23. The power connection sleeve 21 is disposed within the plug-in sleeve 13. One end of the wiring sleeve 22 is connected to the power connection sleeve 21, and the other end extends toward the wiring assembly 3. The plug-in positioning post 23 is disposed at the axis of the power connection sleeve 21. Specifically, a connecting sleeve 221 is disposed at one end of the wiring sleeve 22, and a fixing disk 231 is disposed at one end of the plug-in positioning post 23. One end of the power connection sleeve 21 is disposed on the connecting sleeve 221, and the fixing disk 231 is fixed to the connecting sleeve 221. In this embodiment, the nested design of the power connection sleeve 21 and the plug-in sleeve 13 enhances the stability and reliability of the electrical connection and effectively resists interference with contact performance caused by external environmental factors. The extended design of the wiring sleeve 22 not only optimizes the cable layout, but also facilitates precise docking with the wiring assembly 3, reducing assembly difficulty and error rate. In particular, the insertion positioning post 23, located at the axis of the power connection sleeve 21, combined with the fastening method of the fixing plate 231 and the connecting sleeve 221, ensures precise alignment and secure locking of the connector during insertion, preventing poor contact caused by vibration or impact. This design not only improves the overall durability of the connector, but also significantly enhances energy transmission efficiency and safety.

The precise combination of the locking sleeve 31 , the sealing sleeve 32 and the threaded sleeve 33 achieves efficient clamping of the sealing sleeve 32 through the interaction between the pressing inclined surface 331 and the clamping portion 332 , thereby further enhancing the sealing effect.

[0030] The locking chamber 14 is provided with a sliding cavity 142, and the slider 41 is provided with a sliding portion 411, which is slidably arranged in the sliding cavity 142. In this embodiment, the slider 41 is allowed to move smoothly within the sliding cavity 142, which not only achieves fast and precise positioning and locking of the connector, but also enhances the smoothness and reliability of the connection process. The precise fit between the sliding cavity 142 and the sliding portion 411 effectively prevents loosening or misalignment during the connection process, ensuring the continued stable operation of the energy storage connector in high-load and high-vibration environments.

[0031] One end of the locking chamber 14 is provided with a slot 143, and the baffle 44 is provided with a buckle 441, which is used to engage with the slot 143 to close one end of the locking chamber 14. In this embodiment, by simply and precisely snapping the buckle 441 on the baffle 44 into the slot 143 of the locking chamber 14, the locking assembly 4 is quickly closed and locked, effectively preventing connection interruption or damage caused by unauthorized operation or accidental touch, and enhancing the stability and reliability of the device operation.

[0032] The above embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
