[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 1-4 This utility model provides a power connector with an anti-detachment structure, 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. A snap-fit ​​assembly is provided between the first connecting shell 4 and the second connecting shell 5. The snap-fit ​​assembly includes a fixing tube 6 fixedly installed at one end of the second connecting shell 5. A slot 7 is opened on the surface of the fixing tube 6. A snap-fit ​​block 8 is fixedly connected to the inner wall of the first connecting shell 4 at the corresponding position of the slot 7. The surface of the snap-fit ​​block 8 snaps against the inner wall of the slot 7. An elastic clamping assembly is provided at one end of the inner cavity of the first connecting shell 4 for pressing and fixing the first connecting shell 4 and the second connecting shell 5 together. The elastic clamping assembly includes a clamping ring 10 slidably installed in the inner cavity of the first connecting shell 4. One side of the clamping ring 10 is attached to one end of the fixing tube 6. Several sets of compression springs 11 are fixedly installed on the other side of the clamping ring 10. The end of the compression spring 11 away from the clamping ring 10 is fixedly connected to the inner wall of the first connecting shell 4.

[0024] By using the clamping component and the snap-fit ​​component together, the male connector 1 and the female connector 2 can be snapped together to prevent them from falling off. Specifically, when the male connector 1 and the female connector 2 are inserted together, the fixing tube 6 will be inserted into the inner cavity of the first connecting shell 4 and squeeze the compression spring 11. At this time, the user can rotate the second connecting shell 5, rotate the slot 7 to the position of the locking block 8, and then release the second connecting shell 5. At this time, the reaction force generated by the compression spring 11 will push the fixing tube 6 to move through the clamping ring 10, so as to clamp the locking block 8 in the inner cavity of the slot 7, thereby clamping and fixing the male connector 1 and the female connector 2 together.

[0025] The clamping ring 10 and the first connecting shell 4 are further provided with a guide assembly to improve their movement stability. The guide assembly includes a guide rod 12 fixedly installed on one side of the clamping ring 10, and a guide hole 13 corresponding to the guide rod 12 is opened at one end of the first connecting shell 4. The surface of the guide rod 12 is slidably connected to the inner wall of the guide hole 13. The guide assembly improves the movement stability of the clamping ring 10, and the clamping ring 10 drives the guide rod 12 to slide on the inner wall of the guide hole 13 when it moves.

[0026] It is worth noting that the surface of the fixed tube 6 is provided with a movable groove 9 that is adapted to the locking block 8, and the inner wall of the movable groove 9 is slidably connected to the surface of the locking block 8. The movable groove 9 provides space for the locking block 8 to move. When connecting the male connector 1 and the female connector 2, the user needs to align the movable groove 9 with the position of the locking block 8 and then insert the male connector 1 into the female connector 2.

[0027] Furthermore, 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 is formed 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 setting up the rotating assembly, the second connecting shell 5 and the male connector 1 can be rotatably mounted together. When the second connecting shell 5 is rotated, the rotation of the second connecting shell 5 will drive the annular groove 15 on its inner wall to rotate on the surface of the retaining ring 14.
