[0036] like Figures 1-6 As shown, Figure 1 This is a three-dimensional structural diagram of the connecting components; Figure 2 This is a breakdown diagram of the connecting structural components; Figure 3 This is a partial structural diagram of the connecting components; Figure 4 This is a side view of the connecting structural component; Figure 5 for Figure 4 Cross-sectional view of CC in the middle; Figure 6 for Figure 4 A cross-sectional view of component AA. The connecting structure includes a sleeve 1, a connector 2, a fixing body 3, and a conductor 4. The connector 2 is disposed within the sleeve 1, and the fixing body 3 is fitted onto the connector 2, securing the connector 2 within the sleeve 1 to prevent it from sliding out. The conductor 4 is disposed within the connector 2. When an external pin is inserted into a designated position and contacts the conductor 4, current can flow between the connector 2, the conductor 4, and the pin.

[0037] Please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the three-dimensional structure of sleeve 1; Figure 8This is another three-dimensional structural diagram of the sleeve 1. The sleeve 1 has a first receiving hole 11 and multiple limiting grooves 12. The first receiving hole 11 is opened longitudinally, and the multiple limiting grooves 12 are distributed at intervals along the outer periphery of the first receiving hole 11. At the same time, the limiting grooves 12 communicate with the first receiving hole 11, and the connecting body 2 is located inside the first receiving hole 11. Further, the sleeve 1 also has at least one guide groove 13, which is arranged adjacent to the limiting grooves 12, and the opening direction of the guide groove 13 and the limiting groove 12 is the same. The guide groove 13 communicates with the first receiving hole 11. Furthermore, one end of the sleeve 1 is also provided with a support block 14, and one end of the connecting body 2 abuts against the support block 14. Specifically, the support block 14 has an insertion port 141 and multiple disassembly ports 142. The insertion port 141 passes through the support block 14 and communicates with the first receiving hole 11. The diameter of the insertion port 141 is smaller than the diameter of the first receiving hole 11. Multiple disassembly ports 142 are distributed around the insertion port 141, and each of the multiple disassembly ports 142 communicates with a multiple limiting groove 12, that is, one disassembly port 142 corresponds to one limiting groove 12. In this embodiment, the sleeve 1 is cylindrical, and the first receiving hole 11, the limiting groove 12, the guide groove 13, the insertion port 141 and the disassembly port 142 are all opened along the axial direction, that is, the axial direction of the sleeve 1 is the same as the longitudinal direction.

[0038] Please review Figures 1-6 The connector 2 has a second receiving hole 21, which is longitudinally oriented and communicates with the insertion port 141. External pins enter the second receiving hole 21 through the insertion port 141. Furthermore, the connector 2 also has a positioning port 22, which communicates with the second receiving hole 21. The fixing body 3 is fixedly connected to the fixing body 2 through the positioning port 22. It should be noted that the positioning port 22 is a structure required for electroplating the connector 2. In other words, this invention fully utilizes the structure on the connector 2, not only improving the fixing effect between the fixing body 3 and the connector 2, but also reducing the cost of additional openings, thereby lowering the overall cost.

[0039] Please review Figures 2-6The fixing body 3 has multiple limiting pieces 31, which are arranged around the outer surface of the fixing body 3 at intervals and extend away from the fixing body 3. The multiple limiting pieces 31 correspond to multiple limiting grooves 12. When the connecting body 2 is inserted into the first receiving hole 11 of the sleeve 1, the limiting pieces 31 are engaged in the limiting grooves 12 to prevent the connecting body 2 from detaching from the sleeve 1. When it is necessary to remove the connecting body 2 from the first receiving hole 11, an external disassembly tool is inserted into the limiting groove 12 through the disassembly port 142. During this process, the limiting pieces 31 will disengage from the limiting groove 12, that is, the disassembly tool pushes the limiting pieces 31 to deform towards the connecting body 2. At this time, the connecting body 2 can be directly removed from the first receiving hole 11. In this embodiment, there are four limiting pieces 31, and correspondingly, there are also four limiting grooves 12 and four disassembly ports 142. The disassembly tool can be an existing sheet-like tool with a certain degree of hardness.

[0040] Furthermore, the fixing body 3 also has a guide plate 32, which also extends outward. The guide plate 32 is slidably connected to the guide groove 13 inside the sleeve 1. In use, the guide plate 32 on the fixing body 3 is first placed in the guide groove 13, and then the connecting body 2 is pushed into the first receiving hole 11. Through the cooperation between the guide plate 32 and the guide groove 13, the accuracy and stability of the assembly process of the connecting body 2 can be ensured. In this embodiment, there are two guide plates 32, which are arranged opposite to each other, further improving the stability of the connecting body 2 during the assembly process.

[0041] Furthermore, the fixing body 3 also has a deformation opening 33, a first positioning piece 34, and a second positioning piece 35. The deformation opening 33 is opened along the longitudinal direction of the fixing body 3 and penetrates a part of the fixing body 3. The deformation opening 33 allows the fixing body 3 to deform within a certain range, facilitating assembly and disassembly. The first positioning piece 34 and the second positioning piece 35 are located on both sides of the deformation opening 33. The first positioning piece 34 and the second positioning piece 35 are both snapped into the positioning opening 22. The portions of the first positioning piece 34 and the second positioning piece 35 within the second receiving hole 21 are bent in a direction away from each other to achieve a fixed connection between the fixing body 3 and the connecting body 2.

[0042] In another embodiment, in order to improve the stability of the connection between the fixing body 3 and the connecting body 2, a plurality of first positioning pieces 34 and a plurality of second positioning pieces 35, all located in the positioning port 22, can be provided. The plurality of first positioning pieces 34 are located on the same side and are distributed at intervals along the longitudinal direction, and the plurality of second positioning pieces 35 are located on the same side and are distributed at intervals along the longitudinal direction.

[0043] In this embodiment, the fixing body 3 is made of metal. During the charging process, the connector 2 will emit a lot of heat. If it is made of plastic, prolonged exposure to heat will cause the plastic to become brittle, making it easy to break and increasing the later maintenance costs. If metal is used, the brittleness is avoided, the service life is extended, and the cost is reduced.

[0044] Please review Figure 2 , Figure 3 and Figure 5 The conductor 4 is located within the second receiving hole 21. After the external pin is inserted into the second receiving hole 21, the conductor 4 wraps around the outer surface of the pin to facilitate current conduction. Specifically, the conductor 4 is made of a material with high conductivity and high yield strength, such as copper. In this embodiment, the conductor 4 is an existing torsion spring, crown spring, or similar product.

[0045] Preferably, the connecting structure further includes a sealing body 5, which is sleeved on the outer surface of the connecting body 2. When the connecting body 2 is inserted into the first receiving hole 11, the sealing body 5 is located inside the first receiving hole 11, and the outer surface of the sealing body 5 abuts against the wall of the first receiving hole 11. The setting of the sealing body 5 can reduce the risk of liquid entering the first receiving hole 11 and protect the connecting structure.

[0046] In summary, by cooperating with the multiple limiting pieces 31 on the fixing body 3 and the multiple limiting grooves 12 on the sleeve body 1, multiple limiting points in different directions are established between the fixing body 3 and the sleeve body 1, thereby achieving a fixed connection between the connecting body 2 and the sleeve body 1. This method can ensure the stability of the connection between the connecting body 2 and the sleeve body 1 for a long time, avoiding affecting the reliability and service life of the entire charging device.

[0047] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
