[0029] The staff inserts the metal terminal 13 on the connecting male connector 1 into the plug hole 23 of the connecting female connector 2. Since a positioning portion 6 is provided on the connecting male connector 1, when the metal terminal 13 extends into the plug hole 23, the positioning portion 6 will enter the engaging area of ​​the rotating engaging portion 7, and drive the rotating engaging portion 7 to rotate in the annular groove 3, thereby prompting the rotating engaging portion 7 to engage with the positioning portion 6, thereby prompting the connecting male connector 1 and the connecting female connector 2 to be connected more tightly, thereby avoiding falling off.

[0030] To improve the efficiency of plugging male connector 1 and female connector 2, please refer to Figure 1-Figure 3In a preferred embodiment, the male connector 1 includes a first shell 11, which is cylindrical and has an integrally formed extension end 111. The extension end 111 is connected to a plurality of metal terminals 13, and the number of the metal terminals 13 is at least three. The female connector 2 includes a second shell 21, and the second shell 21 is provided with three plug holes 23 that cooperate with the metal terminals 13. The three metal terminals 13 and the three plug holes 23 are arranged in a triangular shape.

[0031] An extension end 111 is provided on the first housing 11 , and three metal terminals 13 are provided on the extension end 111 . Three insertion holes 23 are provided on the second housing 21 to facilitate insertion of the three metal terminals 13 into the insertion holes 23 .

[0032] To improve the sealing of the plug connector, see Figure 1 and Figure 3 In a preferred embodiment, a first sealing ring 12 is provided on the outer periphery of the extension end 111 , and a second sealing ring 22 is provided on the outer periphery of the second shell 21 .

[0033] A first sealing ring 12 is provided on the extension end 111 , and a second sealing ring 22 is provided on the second shell 21 , which can enhance the sealing performance after the male connector 1 and the female connector 2 are plugged in, thereby enhancing the waterproof effect of the structure.

[0034] To increase the service life of the wire 4, please refer to Figure 1 and Figure 3 In a preferred embodiment, the ends of the male connector 1 and the female connector 2 that are away from each other are both connected to a wire 4, and the surface of the wire 4 is provided with a waterproof coating.

[0035] By arranging the wire 4 at the ends of the connecting male connector 1 and the connecting female connector 2 and providing a corresponding waterproof coating on the wire 4, the waterproof effect of the entire wire 4 can be enhanced.

[0036] To improve the fastening effect between the positioning portion 6 and the rotating engaging portion 7, please refer to Figure 1-Figure 3 In a preferred embodiment, the positioning portion 6 includes three positioning rods 61, which are arranged in a triangular structure on the first shell 11, and the length of the three positioning rods 61 is less than the length of the extension end 111. A notch 62 is provided at the end of any positioning rod 61 away from the first shell 11, and the rotating clamping portion 7 includes a ring body 71, which is rotatably connected in the annular groove 3. Three clamping holes 72 are provided on the ring body 71, and the clamping holes 72 are used to be clamped in the notch 62 of the positioning rod 61. A bend block 73 is also connected to the ring body 71, and the ring body 71 is a plastic deformable part. At least three push blocks 74 are also connected to the outer periphery of the ring body 71.

[0037] When the metal terminal 13 extends to the inside of the plug hole 23, the three positioning rods 61 enter the engaging area of ​​the rotating engaging portion 7, and the staff drives the entire ring body 71 to rotate circumferentially in the annular groove 3 on the outer periphery of the second shell 21 through the pushing block 74, and prompts the locking hole 72 to be engaged with the notch 62 on the positioning rod 61, thereby making the connection between the first shell 11 and the second shell 21 tighter. This can effectively prevent the male connector 1 and the female connector 2 from falling off. Secondly, when the male connector 1 and the female connector 2 need to be disassembled later, the locking hole 72 is pulled to expand by bending the block 73 so that it is no longer engaged with the notch 62 of the positioning rod 61. At this time, the staff can prompt the ring body 71 to rotate through the pushing block 74, and the locking hole 72 is no longer engaged with the notch 62 of the positioning rod 61, and the staff can disassemble the male connector 1 and the female connector 2.

[0038] In order to better understand the present invention, the following Figure 1-Figure 3 The working process of the wiring harness connector of the present invention is described in detail: when in use, the staff inserts the metal terminal 13 on the extension end 111 of the first shell 11 into the plug hole 23 on the second shell 21, wherein the first sealing ring 12 is provided on the first shell 11 and the second sealing ring 22 is provided on the second shell 21, which can effectively enhance the sealing performance of the male connector 1 and the female connector 2 after being plugged in. When the male connector 1 and the female connector 2 are plugged in, the positioning rod 61 extends to the engaging area of ​​the rotating engaging portion 7, and by pushing the ring body 71, the ring body 7 is engaged. 1 rotates circumferentially in the annular groove 3, and the clamping hole 72 is clamped in the notch 62 of the positioning column, thereby enhancing the tightness of the connection between the male connector 1 and the female connector 2 after insertion. Secondly, when disassembly is required, the diameter of the clamping hole 72 is expanded by pulling the bend block 73, so that the clamping hole 72 is no longer clamped in the notch 62, and then the ring body 71 is driven to rotate by the push block 74, so that the connection between the male connector 1 and the female connector 2 can be disassembled. The device is simple to operate and can effectively enhance the anti-detachment effect of the connection between the male connector 1 and the female connector 2. At the same time, it is more compact and applicable to a wider range of scenarios.
