[0024] 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.

[0025] Please see Figures 1-8In this embodiment of the present invention, a magnetic electrical connector assembly includes a first connector 1, a second connector 3, and a movable sleeve 8. A female connector 2 is located at the center of the first connector 1, and a socket 14 is located on the top of the female connector 2. A male connector 4 is located at the center of the second connector 3, and a plug 19 is located on the top of the male connector 4. The plug 19 is slidably connected to the socket 14. A first sleeve groove 9 is located at the center of the second connector 3, and the movable sleeve 8 is slidably connected within the first sleeve groove 9. A second sleeve groove 13 is located at the center of the first connector 1, and a first magnet 7 is adhered to the bottom of the second sleeve groove 13. The movable sleeve 8 is slidably connected to the second sleeve groove 13, and the top of the movable sleeve 8 is magnetically connected to the first magnet 7. The connection between the movable sleeve 8 and the first magnet 7 improves the insertion and extraction strength of the electrical connector and increases the tensile strength. At the same time, the movable sleeve 8 provides 360° protection for the plug 19 and the socket 14, improving the service life. An annular anti-disengagement groove 23 is provided in the middle of the movable sleeve 8. The top and bottom middle of the first connector 1 are provided with first slots 17. A locking plate 5 is slidably connected in the first slot 17. The top of the locking plate 5 is slidably connected to the anti-disengagement groove 23 to prevent the movable sleeve 8 from slipping and disconnecting the electrical connector, making it more reliable.

[0026] The first connector 1 has a second slot 18 at the top and bottom of the first magnet 7 at the edge position. A sealing cover 6 is slidably connected in the second slot 18. The outer side of the top of the movable sleeve 8 is provided with an annular connecting slope 24. The locking plate 5 can be inserted into the second slot 18 and aligned with the position of the connecting slope 24. When it is necessary to disconnect the electrical connector, the locking plate 5 is inserted into the position of the connecting slope 24 to disconnect the direct contact between the first magnet 7 and the movable sleeve 8, thereby reducing the magnetic force and facilitating disconnection.

[0027] The top of the locking plate 5 is provided with a pull-out auxiliary groove 26, and the bottom of the locking plate 5 is bonded with a second magnet 27 with an arc edge. The magnetic attraction is used to fix the locking plate 5 to the movable sleeve 8 to prevent the locking plate 5 from sliding out of the first slot 17.

[0028] Among them, square guide grooves 21 are symmetrically arranged on both sides of the first sleeve slide groove 9, and two guide sliders 22 are symmetrically arranged at the bottom of the movable sleeve 8. The guide sliders 22 are slidably connected to the guide grooves 21 to improve the sliding stability of the movable sleeve 8. A limit installation groove 20 is provided at the top of the guide groove 21, and a T-shaped limit block 25 is connected in the limit installation groove 20 by screws.

[0029] Among them, a first sealing plate 10 with a "mouth" - shaped structure is provided on the outermost side of the end face of the first connecting member 1. A second sealing square groove 11 is provided inside the first sealing plate 10. A second sealing plate 12 with a "mouth" - shaped structure is provided on the end face of the second connecting member 3. The second sealing plate 12 is slidably connected to the second sealing square groove 11, improving the sealing performance of the electrical connector and preventing water ingress and damage.

[0030] Among them, protection piles 15 and protection holes 16 are respectively provided at diagonal positions on the end faces of the first connecting member 1 and the second connecting member 3. The protection piles 15 and the protection holes 16 on the first connecting member 1 and the second connecting member 3 are slidably connected. The length of the protection pile 15 is greater than or equal to the length of the plug pin of the plug 19, preventing damage to the plug pin caused by misalignment when connecting the plug 19 and the socket 14 and protecting the electrical connector.

[0031] The working principle of the present utility model is as follows: The first connecting member 1 and the second connecting member 3 are docked. The socket 14 and the plug 19 are slidably connected, and the protection column and the protection hole 16 are slidably connected to prevent damage to the plug 19 caused by incorrect insertion. The first sealing plate 10 is slidably connected to the outer side of the end face of the second connecting member 3, and the second sealing plate 12 is slidably connected to the second sealing square groove 11, increasing the connection sealing performance between the first connecting member 1 and the second connecting member 3 and preventing rainwater from entering, making it safe to use. When the plug 19 and the socket 14 are connected in place, the movable sleeve 8 located inside the second connecting member 3 is affected by the first magnet 7 located inside the first connecting member 1. The movable sleeve 8 slides along the first sleeve chute 9 and the second sleeve chute 13 towards the first magnet 7 until the top of the movable sleeve 8 is magnetically fixed to the first magnet 7, increasing the connection strength between the first connecting member 1 and the second connecting member 3. During this process, when the connection inclined surface 24 of the movable sleeve 8 moves to the bottom position of the first chute, the connection inclined surface 24 lifts the locking plug 5 to make the locking plug 5 avoid. When the movable sleeve 8 is in contact with the first magnet 7, the locking plug 5 is snapped into the anti - detachment groove 23 of the movable sleeve 8 under the magnetic attraction of the second magnet 27, preventing the movable sleeve 8 from disconnecting under external force. When actively disconnecting the first connecting member 1 and the second connecting member 3, when the operator is not strong enough to smoothly disconnect the magnetic connection between the movable sleeve 8 and the first magnet 7, the sealing cover plate 6 and the locking plug 5 are pulled out. The locking plug 5 is inserted into the second card slot 18, and the locking plug 5 is pressed so that the tip of the locking plug 5 is inserted between the connection inclined surface 24 and the first magnet 7, disconnecting the connection between the first magnet 7 and the movable sleeve 8, thus facilitating the disconnection of the connection between the first connecting member 1 and the second connecting member 3 and making it convenient to use.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
