Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4This utility model provides a power connector with a sealing mechanism, including a male connector 1 and a female connector 2. The ends of the male connector 1 and the female connector 2 that are far apart from each other are connected to wires 3. The ends of the male connector 1 and the female connector 2 that are close to each other are provided with a connecting component. The connecting component includes a metal connecting rod 16 fixedly installed at one end of the male connector 1. A metal connecting tube 17 corresponding to the metal connecting rod 16 is embedded at one end of the female connector 2. One end of the metal connecting rod 16 is inserted into the inner wall of the metal connecting tube 17. The metal connecting rod 16 and the metal connecting tube 17 are electrically connected to the corresponding wires 3 respectively.

[0022] In this embodiment, the female connector 2 is installed on the equipment. Through the setting of the connecting components, the male connector 1 can be electrically connected to the equipment. During installation, the user can insert the metal connecting rod 16 at one end of the male connector 1 into the inner cavity of the metal connecting tube 17 at one end of the female connector 2 to electrically connect the wire 3 at one end of the male connector 1 to the equipment.

[0023] Preferably, the surfaces of the male connector 1 and the female connector 2 are respectively provided with a first connecting shell 4 and a second connecting shell 5. The first connecting shell 4 is fixedly installed on the surface of the female connector 2, and the second connecting shell 5 is rotatably installed on the surface of the male connector 1 through a rotating assembly. One end of the first connecting shell 4 and the second connecting shell 5 is provided with a mounting hole 13. The inner wall of the mounting hole 13 at one end of the first connecting shell 4 is fixedly connected to the surface of the female connector 2, and the inner wall of the mounting hole 13 at one end of the second connecting shell 5 is rotatably connected to the surface of the male connector 1. A threaded connection assembly is provided between the first connecting shell 4 and the second connecting shell 5. The threaded connection assembly includes a fixing tube 6 fixedly installed at one end of the second connecting shell 5. The surface of the fixing tube 6 is provided with an external thread 7, and the inner wall of the first connecting shell 4 is engraved with an internal thread 8 that meshes with the external thread 7. The first connecting shell 4 and the second connecting shell 5 are installed together by meshing with the external thread 7 and the internal thread 8.

[0024] By using the threaded connection assembly, the first connecting shell 4 and the second connecting shell 5 can be threaded together. After the male connector 1 and the female connector 2 are connected together, the first connecting shell 4, the second connecting shell 5 and the threaded connection assembly can be used to prevent them from falling off. During installation, the user can align the male connector 1 with the female connector 2 and make a preliminary insertion. When the fixing tube 6 at one end of the second connecting shell 5 contacts one end of the first connecting shell 4, the user can rotate the second connecting shell 5 to thread the fixing tube 6 into the inner cavity of the first connecting shell 4. During the tightening process of the second connecting shell 5, the male connector 1 will gradually be inserted into the female connector 2.

[0025] The rotating assembly includes a retaining ring 14 fixedly mounted on the surface of the male connector 1, and an annular groove 15 adapted to the retaining ring 14 on the inner wall of the second connecting shell 5. The inner wall of the annular groove 15 is rotatably connected to the surface of the retaining ring 14. By configuring the rotating assembly, the second connecting shell 5 can be rotatably mounted on the surface of the male connector 1. When the second connecting shell 5 rotates, it causes the annular groove 15 on its inner wall to rotate on the surface of the retaining ring 14.

[0026] Specifically, a first sealing assembly is provided at the contact point between the first connecting shell 4 and the second connecting shell 5. This first sealing assembly includes a mounting groove 9 formed at one end of the second connecting shell 5. An annular sealing gasket 10 is fitted inside the mounting groove 9, with one side of the annular sealing gasket 10 fitting against one end of the first connecting shell 4. Through the provision of this first sealing assembly, after the device is installed, both sides of the annular sealing gasket 10 will respectively fit against one end of the first connecting shell 4 and the second connecting shell 5, thereby sealing the connection between the first connecting shell 4 and the second connecting shell 5.

[0027] Furthermore, a second sealing assembly is provided at the connection between the male connector 1 and the female connector 2. The second sealing assembly includes an annular sealing groove 11 formed at one end of the male connector 1 and the female connector 2. A sealing ring 12 is engaged within the inner cavity of the annular sealing groove 11 at the male connector 1 end, and one side of the sealing ring 12 is in contact with the inner wall of the annular sealing groove 11 at the female connector 2 end. Through the provision of the second sealing assembly, the sealing ring 12 and the annular sealing groove 11 work together to seal the connection between the male connector 1 and the female connector 2.

[0028] In summary, the first sealing component can seal the connection between the first connecting shell 4 and the second connecting shell 5, while the second sealing component can seal the connection between the male connector 1 and the female connector 2. Furthermore, the threaded connection structure between the first connecting shell 4 and the second connecting shell 5 can also play a sealing role to a certain extent. In this device, the power connector is sealed through a triple sealing structure, which can greatly improve its sealing performance.
