It further includes a waterproof structure 3 for preventing water from entering the connection between the plug 2 and the connector body 1. The waterproof structure 3 is installed on the outside of the connection between the plug 2 and the connector body 1; a locking structure 4 for locking the waterproof structure 3. The locking structure 4 is installed inside the waterproof structure 3; a sealing ring 5 for enhancing the sealing between the waterproof structure 3 and the connector body 1. The sealing ring 5 is fixedly embedded on the outside of the connector body 1.

[0023] Please refer to Figure 2 , the waterproof structure 3 includes a first protective cover 301 that can move on the outside of the connector body 1. A second protective cover 302 is hingedly installed on the upper end of the connector body 1. The upper end surface of the first protective cover 301 is movably abutted against the lower end surface of the second protective cover 302. The first protective cover 301 and the second protective cover 302 can cover the connection between the plug 2 and the connector body 1.

[0024] Please refer to Figure 2The upper end surface of the protective cover 1 301 and the lower end surface of the protective cover 2 302 are fixedly embedded with a sealing gasket 1 303, a semicircular sealing ring 304 and a sealing gasket 2 305. The protective cover 1 301 and the semicircular sealing ring 304 on the protective cover 2 302 can form a complete circular ring. The number of sealing gaskets 1 303 is two groups, and they are symmetrically distributed.

[0025] See also Figure 2 The number of the semicircular sealing rings 304 is multiple and they are distributed at equal distances. The second sealing gasket 305 is located between two adjacent semicircular sealing rings 304. The sealing gasket 1 303, the semicircular sealing ring 304 and the second sealing gasket 305 are an integrated structure.

[0026] The working principle of the special connector for vehicle-mounted vision sensors with good waterproof effect: after inserting multiple vehicle-mounted vision sensor plugs 2 into the connector body 1 accordingly, the personnel rotates the protective cover 2 302 to make the protective cover 1 301 and the protective cover 2 302 in a closed state. At this time, the semicircular sealing ring 304 on the protective cover 1 301 and the protective cover 2 302 forms a complete circle wrapped around the outside of the plug 2 wire, and the sealing gasket 1 303, the semicircular sealing ring 304 and the sealing gasket 2 305 on the protective cover 1 301 and the protective cover 2 302 respectively abut against each other, and the inner walls of the protective cover 1 301 and the protective cover 2 302 abut against the sealing ring 5 on the outside of the connector body 1, which can effectively prevent water vapor from entering the connection between the plug 2 and the connector body 1, so that the waterproof effect of the connector body 1 is better.

[0027] Embodiment 2

[0028] See also Figure 4 This embodiment further explains Example 1. Two symmetrically distributed limit sliders 6 are fixedly installed on the upper end of the protective cover 301. The limit sliders 6 are in sliding contact with the connector body 1 through the limit straight grooves. The limit sliders 6 can prevent the protective cover 301 from separating from the connector body 1.

[0029] In this embodiment: before inserting the plug 2 into the insertion slot on the connector body 1, the personnel pulls the protective cover 301 to the left to increase the space between the protective cover 301 and the connector body 1, making it more convenient to insert the plug 2 into the connector body 1. After multiple plugs 2 are plugged in, the personnel moves the protective cover 301 to the right to make the left side wall of the protective cover 301 against the plug 2, which can effectively prevent the plug 2 from detaching from the connector body 1.

[0030] Embodiment 3

[0031] See also Figure 3, this embodiment further illustrates other embodiments. The locking structure 4 includes a movable rod 401 that is inserted and removed from the second protective cover 302. A locking hook 402 is fixedly sleeved on the outer side of the movable rod 401 inside the waterproof structure 3. A slope is provided on the lower end surface of the locking hook 402. A positioning seat 403 is movably sleeved on the outer side of the movable rod 401, and the positioning seat 403 is located on the right side of the locking hook 402. The positioning seat 403 is fixedly connected to the second protective cover 302.

[0032] Please refer to Figure 3 , a spring 404 is also movably sleeved on the outer side of the movable rod 401, and both ends of the spring 404 are fixedly connected to the locking hook 402 and the positioning seat 403 respectively. A locking block 405 is movably abutted against the right side of the locking hook 402. The cross-sectional shape of the locking block 405 is rectangular, and the locking block 405 is fixedly connected to the first protective cover 301.

[0033] In this embodiment: When the second protective cover 302 is rotated and closed, the slope at the lower end of the locking hook 402 will abut against the locking block 405. At this time, the locking block 405 will drive the locking hook 402 to move leftward through the slope of the locking hook 402. When the first protective cover 301 and the second protective cover 302 are completely closed, the locking hook 402 will move back to the right under the drive of the spring 404. At this time, the locking hook 402 hooks the locking block 405, and can lock the first protective cover 301 and the second protective cover 302. When it is necessary to open the first protective cover 301, just pull the movable rod 401 to make the locking hook 402 disengage from the locking block 405.
