[0038] The working principle of the present invention is:

[0039] When the present invention is in use: the waterproof electric wire is connected through the wiring components on the male connector component and the female connector component. When wiring, the waterproof electric wire is passed through the wiring groove 2 on the protective shell 203 and the wiring groove 1 on the protective shell 1 201, and the top screw 706 is rotated to make the top screw 706 away from the terminal 705, and the waterproof electric wire is inserted into the wiring hole in the terminal 705, and then the top screw 706 is rotated to make the top screw 706 move in the direction close to the terminal 705, so that the waterproof electric wire is pressed by the top screw 706 to fix the waterproof electric wire.

[0040] The protective components corresponding to one end of the male connector component and the female connector component are respectively assembled. During assembly, the protective shell 1 201 is rotated onto the connector 2 701 under the action of the thread groove 4 210 and the thread groove 6 703, and the connection between the protective shell 1 201 and the connector 2 701 is waterproofly sealed by the cooperation of the thread groove 4 210 and the sealing ring 4 702. The protective shell 2 203 is rotated onto the protective connector 202 under the action of the thread groove 206 and the thread groove 3 207, and the connection between the protective shell 203 and the protective connector 202 is waterproofly sealed by the cooperation of the sealing groove 205 and the sealing ring 208. The connection between the sealing end 204 and the waterproof wire is waterproofly sealed by the sealing ring 7 on the sealing end 204, and then the waterproof sealing of the waterproof wire is realized by the protective components on both sides of the male connector component and the female connector component, thereby ensuring the safety during use and improving the waterproof level.

[0041] Insert the male connector assembly into the female connector assembly for connection, align the positioning cavity 302 with the limit block 403, push the movable frame 401 so that part of the limit block 403 enters the positioning cavity 302 first to achieve preliminary positioning. At this time, the electrical terminal 106 is facing the position of the corresponding electrical terminal 2 605. Push the female connector 601 to move while rotating the rotating ring 501. The anti-slip grooves of the rotating ring 501 facilitate the rotation of the rotating ring 501. When the rotating ring 501 rotates, the rotating ring 501 enters the slot 1 103 under the action of the thread groove 502 and the thread groove 1 109. At the same time, the plug-in block 603 enters the slot 2 108, and the partition 107 enters the partition groove 604. The connecting post 106 is inserted into the corresponding electrical connecting post 2 605. After being rotated into place, the waterproof seal between the male connector 101 and the rotating ring 501 is realized by the cooperation between the sealing groove 1 and the sealing ring 1 102, and the waterproof seal between the connecting head 104 and the female connector 601 is realized by the cooperation between the sealing groove 105 and the sealing ring 3 606. At the same time, the second locking of the male connector assembly and the female connector assembly is realized. The initial positioning of the limiting block 403 first enters the positioning cavity 302, which facilitates the second locking of the male connector assembly and the female connector assembly, ensures the convenience and stability of the assembly process of the male connector assembly and the female connector assembly, and greatly improves the assembly efficiency while ensuring the sealing and firmness.

[0042] When the locking nut 302 is in the closed position, the locking nut 302 is in the closed position, and the locking nut 302 is in the closed position, so that the locking nut 302 is locked.

[0043] It should be particularly noted that since the volume of each limiting ball 404 that exceeds the side of the adjacent limiting block 403 is greater than or equal to one-third of the volume of the limiting ball 404, and less than one-half of the volume of the limiting ball 404; therefore, it can not only ensure the stability of the connection between the limiting block 403 and the locking cavity 302, but also when the limiting block 403 needs to be separated from the locking cavity 302, the limiting block 403 can be pulled out of the locking cavity 302 by a certain force (the magnitude of the force used is determined by the volume of the limiting ball 404 that exceeds the side of the adjacent limiting block 403), the volume of each limiting ball 404 that exceeds the side of the adjacent limiting block 403 in this embodiment is set to one-third of the volume of the limiting ball 404.
