A female terminal 17 is provided inside the internal connector 7, and the female terminal 17 is electrically connected to the conductive connector 4.

[0025] A first sealing connection assembly is provided between the outer connector 2 and the male terminal 14, and a second sealing connection assembly is provided between the inner connector 7 and the female terminal 17. The outer connector 2 and the inner connector 7 are interlocked and form a sealed connection structure through the first sealing connection assembly and the second sealing connection assembly.

[0026] Furthermore, the first sealing connection assembly includes a second waterproof sleeve 13, a first sealing ring 15, and a first spring 16. The second waterproof sleeve 13 is fixed between the outer connector 2 and the male terminal 14. The first sealing ring 15 and the first spring 16 are provided between the outer connector 2 and the second waterproof sleeve 13. The first sealing ring 15 forms a movable structure between the outer connector 2 and the second waterproof sleeve 13 through the first spring 16. The second sealing connection assembly includes a first waterproof sleeve 8, a second spring 18, and a second sealing ring 19. The first waterproof sleeve 8 is located at the outer end of the female terminal 17 inside the inner connector 7. The second spring 18 and the second sealing ring 19 are provided between the first waterproof sleeve 8 and the inner connector 7. The second sealing ring 19 forms a movable structure between the first waterproof sleeve 8 and the inner connector 7 through the second spring 18, realizing the compression sealing of the first sealing ring 15 and the second sealing ring 19, and ensuring the stability of the sealing connection state.

[0027] Furthermore, the front end of the inner connector 7 is inserted between the outer connector 2 and the second waterproof sleeve 13, and is pressed and connected with the first sealing ring 15. The front end of the second waterproof sleeve 13 is inserted between the first waterproof sleeve 8 and the inner connector 7, and is pressed and connected with the second sealing ring 19. Through the interlocking insertion of layers, a staggered connection structure is formed, and the first sealing ring 15 and the second sealing ring 19 are pressed and sealed to ensure a stable sealing effect at the connection, thereby ensuring the waterproof effect at the connection.

[0028] A mating assembly is provided between the outer connector 2 and the inner connector 7 to fix the connection position of the two.

[0029] Furthermore, the docking assembly includes a locking block 9 and a docking sleeve 11. The locking block 9 is embedded and movably mounted on the second main body 3. A third spring 21 is installed on the lower side of the locking block 9, which enables the locking block 9 to move up and down. The docking sleeve 11 is fixed to the outer end of the outer connector 2, and the inner side of the docking sleeve 11 is provided with an annular locking groove 12. The locking groove 12 is aligned and locked with the locking block 9, which not only facilitates the connection between the locking groove 12 and the locking block 9, but also enables rotation in the locked state, increasing the usability of the connected state.

[0030] Furthermore, a movable sleeve 5 is movably sleeved on the outer side of the second main body 3. A protrusion 6 is provided on the outer side of the movable sleeve 5 to facilitate the displacement of the movable sleeve 5 through the protrusion 6. A pressing slider 20 is fixed on the inner side of the movable sleeve 5. The pressing slider 20 is aligned and connected to the upper side of the locking block 9. The position of the pressing slider 20 can be moved by the displacement of the movable sleeve 5, thereby pressing down the locking block 9 and realizing the separation of the locking block 9 from the locking groove 12, so as to quickly complete the unpacking work of the energy storage connector.

[0031] Working principle: When using this waterproof energy storage connector, first pick up the first body 1 and connect the outer connector 2 to the inner connector 7 on the second body 3. There is a mating sleeve 11 at the outer end of the outer connector 2. The inner diameter of the mating sleeve 11 is much larger than that of the inner connector 7, so it is very convenient to connect the inner connector 7 into the mating sleeve 11. Since the outer diameter of the innermost side of the mating sleeve 11 is equal to the inner diameter of the outer connector 2, it can be ensured that the inner connector 7 can be quickly connected into the outer connector 2.

[0032] When the inner connector 7 is inserted into the outer connector 2, the inner connector 7 is fitted on the outside of the second waterproof sleeve 13, the second waterproof sleeve 13 is fitted on the outside of the first waterproof sleeve 8, and the first waterproof sleeve 8 is fitted on the outside of the male terminal 14. As the outer connector 2 and the inner connector 7 continue to be inserted, the male terminal 14 and the female terminal 17 are finally electrically connected together.

[0033] During the docking process, the outer end of the second waterproof sleeve 13 will contact the second sealing ring 19 between the inner connector 7 and the first waterproof sleeve 8. As the docking continues to deepen, the second waterproof sleeve 13 will squeeze the second sealing ring 19. Under the action of the second spring 18, the second sealing ring 19 and the second waterproof sleeve 13 will be tightly connected. At the same time, the front end of the inner connector 7 will also penetrate into the space between the outer connector 2 and the second waterproof sleeve 13 and squeeze and contact the first sealing ring 15. The first spring 16 will ensure a tight connection.

[0034] After the male terminal 14 and the female terminal 17 are connected, the connecting sleeve 11 is fitted onto the second body 3. The locking block 9 on the second body 3 is engaged in the locking groove 12 inside the connecting sleeve 11 to ensure a stable connection between the first body 1 and the second body 3. At the same time, the outer connector 2 and the second waterproof sleeve 13 are mutually connected with the inner connector 7 and the first waterproof sleeve 8 to form a stable waterproof structure, ensuring the safe use of the energy storage connector.

[0035] When it is necessary to disassemble the energy storage connector, the movable sleeve 5 on the second body 3 can be moved to move the squeezing slider 20 forward. During this process, the locking block 9 is pressed down and hidden inside the second body 3. This enables the locking block 9 to be quickly separated from the locking groove 12, releasing the connection and fixing state of the first body 1 and the second body 3. At the same time, under the action of the first spring 16 and the second spring 18, the separation efficiency can be improved to facilitate the disassembly work.

[0036] The above describes the usage process of this energy storage connector. Any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
