For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Embodiment 1:

[0025] The preferred embodiment of the anti-pulling wire harness connector provided by the present utility model is as Figures 1 to 5 shown: An anti-pulling wire harness connector includes a female connector 1 and a male connector 2, and an anti-pulling and sealing mechanism 3 is arranged between the female connector 1 and the male connector 2;

[0026] The anti-pull sealing mechanism 3 includes a sleeve plate 301, a fixed retaining ring 310 and an L-shaped clamping plate 314. The sleeve plate 301 is fixedly sleeved on the outer wall of the female joint 1, the fixed retaining ring 310 is fixedly sleeved on the outer wall of the male joint 2, the sleeve plate 301 is sleeved on the outer wall of the male joint 2, a piston chamber 302 is opened inside the sleeve plate 301, a piston pad 303 is slidably connected to the inner wall of the piston chamber 302, a groove 307 is opened on the inner wall of the female joint 1, a sealing airbag 308 is fixedly installed on the inner wall of the groove 307, a ventilation groove is opened for communication between the groove 307 and the piston chamber 302, a sealing groove 309 is opened on the outer wall of the male joint 2, the sealing airbag 308 is in close fit with the sealing groove 309, a first limiting rod 304 is fixedly installed on one side of the piston pad 303, a first rod hole 306 is opened for communication between one side of the sleeve plate 301 and the piston chamber 302, the first limiting rod 304 movably penetrates through the first rod hole 306, a first spring 305 is wound around the first limiting rod 304, and the first spring 305 is fixedly installed between one side of the piston pad 303 and the inner wall of the piston chamber 302. A limiting plate 311 is fixedly installed near the bottom end on one side of the sleeve plate 301, a limiting hole 312 is opened on the inner wall of the fixed retaining ring 310, the limiting plate 311 movably penetrates through the limiting hole 312, a clamping groove 313 is opened at the top end of the limiting plate 311, the L-shaped clamping plate 314 is inserted into the clamping groove 313, and the L-shaped clamping plate 314 is slidably connected to one side of the baffle plate.

[0027] Specifically in the above technical solution, when the anti-pulling wire harness connector is in use, the male connector 2 is docked with the female connector 1, so that the terminal connector 4 is inserted into the terminal interface 5, and the sleeve plate 301 is sleeved on the outer wall of the male connector 2. The sleeve plate 301 drives the first limiting rod 304 to contact the fixed retaining ring 310. The fixed retaining ring 310 will squeeze the first limiting rod 304. The first limiting rod 304 drives the piston pad 303 to squeeze the air in the piston chamber 302, so that the squeezed air is transported to the sealing airbag 308 through the ventilation groove, causing the sealing airbag 308 to bulge, and the sealing airbag 308 is filled into the sealing groove 309. The sleeve plate 301 also drives the limiting plate 311 to penetrate through the limiting hole 312. Before the limiting plate 311 penetrates through the limiting hole 312, first pull up the L-shaped clamping plate 314. The L-shaped clamping plate 314 drives the slider 316 to compress the spring, so that the L-shaped clamping plate 314 is not on one side of the limiting hole 312. When the limiting plate 311 penetrates through the limiting hole 312, the L-shaped clamping plate 314 can be released. At this time, the slider 316 will drive the L-shaped clamping plate 314 to insert into the clamping groove 313 under the restoring force of the spring, thereby limiting the limiting plate 311 and completing the connection and fixation of the male connector 2 and the female connector 1. Through the above structure, the female connector 1 and the male connector 2 can be limited and fixed after docking, avoiding the male connector 2 and the female connector 1 from being easily separated when being pulled, thus affecting the normal transmission of data. And by setting the sealing airbag 308, the sealing performance of the male connector 2 and the female connector 1 after docking can be greatly improved, avoiding water from entering the connection part of the female connector 1 and the male connector 2, resulting in a short-circuit phenomenon, and solving the problem that in the existing technical solution, the male connector 2 and the female connector 2 do not have a sealing structure during anti-pulling docking, resulting in poor sealing performance and easy occurrence of water immersion and short-circuit phenomena, thus affecting the normal transmission of data.

[0028] Further, the number of the first limiting rods 304 and the first rod holes 306 is four each, and the first limiting rods 304 are adapted to the first rod holes 306. One end of the male connector 2 is fixedly installed with a terminal connector 4, one end of the female connector 1 is provided with a terminal interface 5, the terminal connector 4 is inserted into the terminal interface 5, and the other ends of the female connector 1 and the male connector 2 are both fixedly connected with wires 8;

[0029] Among them, by setting the first limiting rod 304, the first spring 305 and the piston pad 303 can be limited, ensuring the stability of the first spring 305 during compression and the piston pad 303 during use.

[0030] Further, a slider 316 is fixedly installed on one side of the L-shaped clamping plate 314. A chute 315 is formed on one side of the fixed retaining ring 310. The slider 316 is slidably connected to the chute 315. A second limiting rod 317 is fixedly installed on the inner wall of the chute 315. A second rod hole 318 is formed on the slider 316. The second limiting rod 317 movably penetrates through the second rod hole 318. A second spring 319 is wound around the outer wall of the limiting rod. The second spring 319 is fixedly installed between the top end of the slider 316 and the inner wall of the chute 315.

[0031] Among them, by setting the second limiting rod 317, the slider 316 and the second spring 319 can be limited, ensuring the stability of the slider 316 during sliding and the second spring 319 during compression.

[0032] Further, the number of the limiting plates 311, the limiting holes 312, and the L-shaped clamping plates 314 is four. The limiting plates 311 are adapted to the limiting holes 312, and the L-shaped clamping plates 314 are adapted to the clamping grooves 313.

[0033] Among them, by setting the L-shaped clamping plate 314, the L-shaped clamping plate 314 can be inserted into the clamping groove 313, thereby limiting the limiting plate 311. Embodiment 2:
