[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-6 The utility model provides a technical solution: a new energy storage connector, including a female module 1, a male module 3 and a connecting module 2 connected between the female module 1 and the male module 3. First, the connecting module 2 and the male module 3 are fixedly connected by a locking structure 1 and a locking structure 2 respectively. When any one of the locking structure 1 and the locking structure 2 fails, the other can ensure that the connecting module 2 and the male module 3 will not be separated, forming a double insurance structure, which can ensure that the connecting module 2 and the male module 3 are less likely to be separated, thereby ensuring the stability of the connection of the entire energy storage connector during use.

[0025] Secondly, the female module 1 includes a terminal 11, and a reserved hole 12 is provided at one end of the terminal 11. The reserved hole 12 can be fixedly connected to the plug-in boss 211 by stamping or riveting to ensure conductivity. The other end is fixedly sleeved with a cable waterproof connector 13, which is used to connect external cables. The external movable sleeve of the cable waterproof connector 13 is provided with a nut 14, and the inner wall of the nut 14 is provided with an internal thread 15. The end of the cable waterproof connector 13 will shrink toward the center point after being squeezed by external force. The cable is inserted into the cable waterproof connector 13. After the nut 14 is connected to the external thread 217 of the housing 21 through the internal thread 15, the end of the cable waterproof connector 13 will be squeezed and tightened, thereby clamping the cable, and a sealing ring 4 is also provided at the connection between the nut 14 and the housing 21 to improve the waterproof sealing performance here;

[0026] The connecting module 2 includes a shell 21, and a slot 22 is provided inside the shell 21. The slot 22 allows the terminal shell 31 to be inserted into the interior of the shell 21. The interior of the slot 22 is fixedly connected to the plug-in barrel 23, and the terminal 2 33 is plugged into the interior of the plug-in barrel 23. A reserved slot 1 24 is provided on one side of the shell 21, and an entrance connected to the plug-in barrel 23 is integrally connected to the other side of the shell 21. The surface of the entrance is provided with an external thread 217, and a reserved slot 25 is provided on the edge of the top of the shell 21 (the reserved slot 1 24 is used to accommodate the unlocking handle 28, and the reserved slot 25 is used to accommodate the lock tongue 281). The slot 22, the reserved slot 1 24, and the reserved slot 25 are connected. The bottom of the reserved slot 1 24 is fixedly connected to the limiting member 1 26, and a pin shaft 27 is fixedly inserted into the side of the shell 21. The outside of the pin shaft 27 is rotatably connected to the unlocking handle 28 (the unlocking handle 28 can be centered on the pin shaft 27, The top of the unlocking handle 28 is integrally connected with a lock tongue 281 (when the unlocking handle 28 is in a vertical state, the lock tongue 281 is engaged with the step groove 32), the inner side of the bottom of the unlocking handle 28 is fixedly connected with the limit member 282, and the limit member 282 and the limit member 1 26 are commonly connected with a spring 29 (when the spring 29 is in its original length state, the unlocking handle 28 is in a vertical state), the interior of the plug-in cylinder 23 is fixedly connected with a conductive cylinder 210, the bottom end of the conductive cylinder 210 is integrally connected with a plug-in boss 211, and the interior of the conductive cylinder 210 is fixedly connected with a crown spring 212 (the crown spring 212 is large at both ends and small in the middle. The parts at both ends contact the inner wall of the conductive cylinder 210, and the middle part contacts the surface of the terminal 2 33 to achieve conductivity), and the bottom end of the conductive cylinder 210 is fixedly connected with a locking buckle 213;

[0027] The male module 3 includes a terminal shell 31, and a step groove 32 is provided on the outside of the terminal shell 31 (the step groove 32 is provided so that it can engage with the lock tongue 281), and a terminal 2 33 is fixedly inserted inside the terminal shell 31. The bottom end of the terminal 2 33 is a hollow structure, and an annular slot 34 is provided inside the hollow structure.

[0028] Among them, the locking structure 1 is composed of 34 and a locking buckle 213. The top of the locking buckle 213 is integrally connected with a locking contact 215. The bottom of the locking contact 215 is provided with a locking slot 214 with a diameter smaller than the top diameter of the locking buckle 213. The inside of the locking contact 215 is provided with a residual groove 216 (the setting of the residual groove 216 is to allow the locking contact 215 to be squeezed when the terminal 2 33 is inserted, so that the diameter of the locking contact 215 can be reduced, so that the locking contact 215 can enter the hollow structure at the bottom end of the terminal 2 33, so that the locking contact 215 and the annular slot are locked. 34 are engaged together), when the connecting module 2 and the male module 3 are connected, the bottom end of the terminal 2 33 is inserted into the outside of the engaging contact 215, and the engaging contact 215 is engaged and fixed with the annular engaging groove 34. The locking structure 2 is composed of the step groove 32, the unlocking handle 28, the spring 29, and the lock tongue 281. When the connecting module 2 and the male module 3 are connected, the unlocking handle 28 is pushed outward by the spring 29 to deflect, so that the lock tongue 281 is engaged and fixed with the step groove 32. When unlocking, press the bottom end of the unlocking handle 28 to allow the unlocking handle 28 to drive the lock tongue 281 to deflect, and the lock tongue 281 can be disengaged from the step groove 32.

[0029] During use, when connecting the energy storage connector, the connection module 2 and the female module 1 are an integral unit, which can also be collectively referred to as the female connector. That is, the two are initially assembled. First, the conductive end of the cable is inserted into the cable waterproof connector 13, so that the conductive end surface of the cable contacts the terminal 11 to ensure conductivity. Then, the nut 14 is connected to the housing 21 through the thread, and the cable is connected and fixed.

[0030] Subsequently, the male module 3 needs to be inserted into the connecting module 2. When inserting, the bottom end of the unlocking handle 28 needs to be pressed first. The unlocking handle 28 will deflect, so that the locking tongue 281 will be separated from the reserved groove 25. Then the entire male module 3 is inserted into the housing 21. After being inserted to the bottom, the second terminal 33 is locked and fixed with the locking buckle 213. At this time, the unlocking handle 28 is released and reset to a vertical position. The locking tongue 281 is locked with the step groove 32 to form a second locking structure, which doubles the protection against falling off.

[0031] When the male module 3 needs to be removed, similarly, press the bottom end of the unlocking handle 28, the unlocking handle 28 will deflect, and the locking tongue 281 and the step groove 32 will no longer be engaged. Then, pull out the male module 3 with force, and the terminal 2 33 and the locking buckle 213 will be separated.
