In the initial stage, the second rubber ring 101 and the second annular airbag 102 are both inserted into the annular groove 11. A plurality of waterproof rings 10 are provided here to improve the waterproof effect. In this way, when the second annular airbag 102 is inflated and lifted up, it further lifts up the second rubber ring 101 and the docking sleeve 2. 2 inner walls are tightly fitted to form several waterproof barriers, and in this design, the second rubber ring 101 can be inserted into the annular slot 11 together with the second rubber ring 101 in the initial stage when the second annular airbag 102 is not inflated by the first annular airbag 9, so as to facilitate the insertion of the docking sleeve 22, and according to the linkage effect described below, when the docking sleeve 22 is inserted into the fixing sleeve 8, the first annular airbag 9 is automatically squeezed to inflate the second annular airbag 102, so that it is pressed against the docking sleeve 22, thereby achieving a better waterproof effect and facilitating disassembly.

The outer surface of the second wedge block 64 is adapted to fit with the inner circle of the first annular airbag 9 so that when it is lifted by the first wedge block 63, the first annular airbag 9 can be better squeezed, so as to achieve the purpose of squeezing the gas in the first annular airbag 9 into a plurality of second annular airbags 102; it should be added here that a plurality of second annular airbags 102 are connected to the first annular airbag 9 (not shown in the figure), and a plurality of return springs are provided in the first annular airbag 9, so that when disassembly, when the squeezing of the second wedge block 63 on the second wedge block 64 is released, the first annular airbag 9 will automatically reset, thereby sucking back the gas in the plurality of second annular airbags 102, making the second annular airbags 102 deflated, thereby pulling the second rubber ring 101 into the annular groove 11 for easy disassembly.

[0029] It is also worth mentioning that from Figure 3 , Figure 5 and Figure 8-Figure 9 It can be seen that the outer wall of the first annular airbag 9 is flush with the outer walls of the rotating sleeve 61 and the fixed sleeve 8, and is made of hard material.

[0031] Combination Fig.10 , an arc groove 25 adapted to the trigger assembly 7 is symmetrically provided in the docking sleeve 22, so that when the docking sleeve 22 is inserted into the second conductive terminal 3 or the fixed sleeve 8, the inner wall of the first half of the docking sleeve 22 will squeeze the trigger block 72 into the trigger box 71, and then when the docking sleeve 22 moves to the arc groove 25 therein and contacts the trigger block 72, the trigger block 72 pops up and is inserted into the arc groove 25. Due to the oblique arc structure of the arc groove 25, and then in the process of the docking sleeve 22 continuously moving forward, the trigger block 72 slides in the arc groove 25, thereby driving the rotating sleeve 61 to rotate, and then driving the first wedge block 63 to rotate through the rotating ring 62, and then because the first wedge block 63 and the second wedge block 64 are mutually wedge-shaped structures, the second wedge block 64 will be squeezed to make the guide rod 65 on it slide along the guide groove 66 on the fixed sleeve 8, thereby squeezing the inner side of the first annular airbag 9.

It should be added that the limiting block 14 is provided because, first, it is convenient for the docking sleeve 22 to be inserted into the rotating sleeve 61 On the one hand, the first rubber ring 24 is used to make the first rubber ring 24 have a plurality of springs, and on the other ...

[0033] For further information, see Figure 2-Figure 4As shown, an active cavity 15 is provided in the mounting base 1, a snap-fit ​​assembly 16 is arranged in the active cavity 15, a control assembly 18 for controlling the snap-fit ​​assembly 16 is also provided in the mounting base 1, a first snap-fit ​​groove 17 adapted to the snap-fit ​​assembly 16 is provided in the plug socket 4, a snap-fit ​​block 19 adapted to the snap-fit ​​assembly 16 is arranged in the first snap-fit ​​groove 17, and the snap-fit ​​assembly 16 is snapped into the first snap-fit ​​groove 17 through the snap-fit ​​block 19 to prevent the plug socket 4 from falling off.

[0034] The locking assembly 16 comprises a mounting rod 161 fixedly connected in the movable cavity 15, and a locking rod 162 is rotatably connected to the mounting rod 161. A torsion spring 163 is provided at the connection between the mounting rod 161 and the locking rod 162, one end of the torsion spring 163 is fixedly connected to the mounting rod 161, and the other end is fixedly connected to the locking rod 162; the torsion spring 163 always has a tendency to cause the locking rod 162 to rotate upward, ensuring that the locking rod 162 always has the tendency to rotate upward so that it can always maintain a limited state when it is engaged with the locking block 19, and there is space for the locking rod 162 to rotate up and down in the movable cavity 15 and the first locking groove 17. In this way, when the limit of the locking block 19 and the locking rod 162 is released, space is left for the rotation of the locking rod 162, and one end of the locking rod 162 away from the mounting rod 161 extends to the outside of the movable cavity 15 and forms a locking portion of a wedge-shaped structure, and the locking portion of the movable cavity 15 is adapted to the locking block 19.

[0036] It is worth mentioning that Figure 3 , Figure 5 and Fig.10As shown, the length of the arc groove 25 is adapted to the angle of rotation required by the first wedge block 63 when the trigger block 72 drives the first wedge block 63 to squeeze the first annular airbag 9, and the gas discharged from the first annular airbag 9 meets the requirement of lifting the waterproof ring 10 and pressing against the inner wall of the docking sleeve 22. Combined with the above description of the first annular airbag 9, that is, when the trigger block 72 moves to the end in the arc groove 25, the first annular airbag 9 drives the first wedge block 63 to squeeze the first annular airbag 9 through the second wedge block 64. At this time, the gas squeezed out of the first annular airbag 9 is just enough for a number of second annular airbags 102 to use, so that the second rubber ring 101 thereon presses against the inner wall of the docking sleeve 22; and combined with Fig.11 and Fig.12 As shown, when the arc groove 25 begins to contact the trigger block 72, the limit block 14 begins to contact the limit groove 20; secondly, when the trigger block 72 reaches the end of the arc groove 25, the limit block 14 completely enters the docking sleeve 22, and at this time the engaging assembly 16 engages with the engaging block 19 in the first engaging groove 17.

[0037] How to use this product: When in use, align the docking sleeve 22 of the plug socket 4 with the rotating sleeve 61 and insert it. When the second annular cavity 21 is about to contact the sleeve 12, adjust the plug socket 4 so that the limit groove 20 thereon is inserted into the limit block 14, and then continue to push forward. At this time, the trigger block 72 is just inserted into the arc groove 25, and then the limit block 14 is engaged with the limit groove 20 to limit the rotation of the plug socket 4. As a result, when the plug socket 4 continues to be pushed and inserted, the trigger block 72 drives the rotating sleeve 61 to rotate, and then drives the first wedge block 63 to squeeze the second wedge block 64, so that it squeezes the inner side of the first annular airbag 9, and discharges the gas therein into a plurality of second annular airbags 102. Then the second annular airbags 102 are inflated to lift up the second rubber ring 101, so that it is removed from the ring. The first rubber ring 24 is pushed up in the annular card slot 11 and fits the inner wall of the docking sleeve 22. When the first rubber ring 24 is inserted into and pressed against the inner wall of the first annular card cavity 13, the clamping rod 162 is also just inserted into the clamping block 19 in the first card slot 17 to complete the limit of the plug socket 4. At this time, the gas in the first annular airbag 9 is just squeezed into a plurality of second annular airbags 102. At this time, the second rubber ring 101 completes the work of pressing against the inner wall of the docking sleeve 22, and the first rubber ring 24 is squeezed against the inner wall of the first annular card cavity 13, thereby realizing a double-layer waterproof barrier. In addition, during the advancement process, the second rubber ring 101 is slowly raised from the annular card slot 11 and pressed against the inner wall of the docking sleeve 22, thereby greatly reducing the wear on the inner wall of the docking sleeve 22 and facilitating installation and disassembly. During disassembly, the pressing rod 182 is pressed to squeeze the engaging rod 162 to disengage it from the engaging block 19 , and then the plug socket 4 can be pulled out.

[0038] This effectively solves the problem that the rubber ring in the existing energy storage connector cannot meet the requirements of waterproofing and convenient installation and disassembly.
