Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material and graphite as the negative electrode material.

[0003] The prior art patent application with publication number CN222072326U proposes to set a male terminal plug on the busbar of the lithium battery PACK and a quick-connect female terminal on one end of the acquisition line of the protection board. The male and female terminals can be quickly assembled without the need for wire bonding.

[0004] However, by inserting the male prong into the female quick-connect terminal, the connection stability between them is poor.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] First Embodiment

[0026] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the first embodiment of a novel lithium battery PACK bus structure provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural schematic of the protective sleeve. Figure 3 for Figure 2 The diagram shows the internal structure of the protective sleeve. A novel lithium battery PACK bus structure includes: a connector 1, two male terminal inserts 2, two protective sleeves 3, two fixing devices 4, and two female terminal connectors 5;

[0027] One end of each of the two male end plugs 2 is fixedly connected to the connecting frame, the two protective sleeves 3 are respectively fixedly connected to the surface of the two male end plugs 2, and the two female end connecting sleeves 5 are respectively slidably connected to the inside of the two protective sleeves 3;

[0028] The fixing device 4 includes a rotating rod 41, a torsion spring 42, a fixing plate 43, a fixing block 44, and a fixing groove 45. The rotating rod 41 is rotatably connected to the inside of the female end connecting sleeve 5. The torsion spring 42 is sleeved on the surface of the rotating rod 41. One side of the fixing plate 43 is fixedly connected to one side of the rotating rod 41. One side of the fixing block 44 is fixedly connected to one side of the fixing plate 43. The fixing groove 45 is opened inside the protective sleeve 3.

[0029] Two rectangular blocks are fixedly connected to one side of the rotating rod 41. One side of the fixing plate 43 is fixedly connected to one side of the rotating rod 41 through the two rectangular blocks. Two torsion springs 42 are sleeved on the surface of the rotating rod 41 and located between the two rectangular blocks.

[0030] The fixing block 44 is a triangular block. One side of the fixing block 44 is fixedly connected to one side of the fixing plate 43, and is used to cooperate with the fixing groove 45 to fix the female end connecting sleeve 5 and the protective sleeve 3.

[0031] The two ends of the torsion spring 42 are respectively fixedly connected to the inside of the fixing plate 43 and the female end connecting sleeve 5.

[0032] A sealing ring 6 is fixedly connected to one side of the female end connecting sleeve 5 and the inside of the protective sleeve 3.

[0033] Two sealing rings 6 are used to seal between the female end connecting sleeve 5 and the protective sleeve 3.

[0034] The sealing ring 6 is provided with a connecting device 7 inside. The connecting device 7 includes multiple connecting grooves 71 and multiple connecting blocks 72. The multiple connecting grooves 71 are all opened inside the sealing ring 6, and the multiple connecting blocks 72 are slidably connected to the interior of the multiple connecting grooves 71.

[0035] One end of each of the multiple connecting blocks 72 is fixedly connected to one side of the sealing ring 6.

[0036] Multiple connecting grooves 71 are formed inside a sealing ring 6, while one end of multiple connecting blocks 72 is fixedly connected to one side of another sealing ring 6. The multiple connecting blocks 72 cooperate with the multiple connecting grooves 71 to increase the contact area between the two sealing rings 6, thereby increasing the sealing effect.

[0037] The working principle of the novel lithium battery PACK bus structure provided by this utility model is as follows:

[0038] In use, the female connector 5 is inserted into the protective sleeve 3 and then connected to the male connector 2.

[0039] When the female end connecting sleeve 5 is inserted downward into the protective sleeve 3, the two fixing blocks 44 come into contact with the surface of the protective sleeve 3, thereby causing the two fixing blocks 44 to rotate along the inclined plane and drive the two fixing plates 43 to rotate to one side, thereby causing the two rotating rods 41 to rotate to one side, while the two torsion springs 42 are tightened.

[0040] When the female end connecting sleeve 5 moves to the appropriate position, the two torsion springs 42 reset, thereby driving the two fixing plates 43 connected to the two fixing blocks 44 to rotate and reset to one side. After entering the interior of the two fixing grooves 45 respectively, they limit the distance between the female end connecting sleeve 5 and the protective sleeve 3.

[0041] Compared with related technologies, the novel lithium battery PACK bus structure provided by this utility model has the following beneficial effects:

[0042] This utility model provides a novel lithium battery PACK bus structure. After the female end connecting sleeve 5 is inserted into the inside of the protective sleeve 3, it is connected to the male end plug 2. The female end connecting sleeve 5 and the protective sleeve 3 are fixed by the fixing device 4, thereby increasing the stability of the connection. At the same time, the protective sleeve 3 protects the female end connecting sleeve 5 and the male end plug 2 to prevent oxidation.

[0047] The sealing cover 9 is rotatably connected to the surface of the female end connecting sleeve 5. It is used to rotate the sealing cover 9 to one side, thereby driving the limiting block 10 to rotate to one side, and limiting the distance between the limiting block 10 and the limiting sleeve 8, and between the female end connecting sleeve 5 and the male end insert 2.

[0048] The working principle of the novel lithium battery PACK bus structure provided by this utility model is as follows:

[0049] In use, after the female end connecting sleeve 5 is inserted into the inside of the limiting sleeve 8 and connected to the male end insert 2, the sealing cover 9 is rotated to one side, thereby causing the limiting block 10 to rotate to one side inside the limiting sleeve 8, so that the limiting block 10 moves to the appropriate position inside the limiting sleeve 8.
