When the male terminal 20 is connected with the female terminal 30, the sealing ring 41 is inserted into the sealing groove 33 and the arc-shaped groove 34, and the part of the sealing ring 41 inserted into the arc-shaped groove 34 is expanded in an expanded shape along the shape of the sealing groove 33.

[0036] Referring to Figure 3 and Figure 4 , the inner wall of the sliding sleeve 40 is provided with a water stopping cavity 42, the opening of the water stopping cavity 42 is opposite to the side of the male terminal 20, and the water stopping cavity 42 is located on the side of the sliding sleeve 40 close to the end surface of the male terminal 20 away from the wire harness 10. The inner wall of the sliding sleeve 40 is fixedly provided with an upper water stopping plate 43, which is located in the water stopping cavity 42 and is fixedly connected with the inner wall of the water stopping cavity 42 opposite to the side of the male terminal 20, and the upper water stopping plate 43 is perpendicular to the side of the male terminal 20. The side of the upper water stopping plate 43 close to the male terminal 20 is fixedly provided with an upper clamping edge 44, which is bent towards the direction of the male terminal 20 away from the wire harness 10.

[0037] Referring to Figure 3 and Figure 4 , the side of the male terminal 20 is fixedly provided with a lower water stopping plate 22, the side of the lower water stopping plate 22 away from the male terminal 20 is fixedly provided with a lower clamping edge 23, and the lower clamping edge 23 is bent towards the direction of the upper clamping edge 44. A distance for the sliding of the sliding sleeve 40 is reserved between the upper water stopping plate 43 and the lower water stopping plate 22. The sides of the upper water stopping plate 43 and the lower water stopping plate 22 facing each other are both provided with a sealing pad 24. The upper water stopping plate 43 and the lower water stopping plate 22 abut each other, and the upper clamping edge 44 and the lower clamping edge 23 are clamped with each other.

[0038] Referring to Figure 5 and Figure 6, the inside of the sliding sleeve 40 is also provided with control cavities 45, which are located on the side of the sliding sleeve 40 away from the water-stopping cavity 42. The control cavities 45 are two, and the two control cavities 45 are respectively located on the upper and lower surfaces of the male terminal 20, so as to facilitate the pressing by fingers. The side surface of the male terminal 20 is elastically provided with a stop spring 25, the end of the stop spring 25 protrudes from the side surface of the male terminal 20, and the end of the stop spring 25 faces away from the end of the male terminal 20 away from the wire harness 10,

[0039] The control cavities 45 of the sliding sleeve 40 are fixedly provided with a top-holding block 46, which is located on the side of the control cavities 45 close to the water-stopping cavity 42. The top-holding block 46 is fixedly connected to the side surface of the control cavities 45 facing the male terminal 20, and an insertion sliding gap 47 for inserting the stop spring 25 is provided between the top-holding block 46 and the side surface of the male terminal 20. The depth of the insertion sliding gap 47 is greater than the sliding distance of the sliding sleeve 40, and the height of the insertion sliding gap 47 is less than the normal spring-up height of the stop spring 25.

[0040] Referring to Figure 5 and Figure 6 , the corner of the top-holding block 46 is provided with a sliding slope 48 for guiding the stop spring 25 to slide into the insertion sliding gap 47. The sliding slope 48 is located at the corner of the side of the top-holding block 46 facing the stop spring 25, and the spring-up end of the stop spring 25 slides against the sliding slope 48. The side of the top-holding block 46 away from the water-stopping cavity 42 is fixedly provided with a top-holding edge 49, which protrudes from the side of the top-holding block 46. When the sealing ring 41 is inserted into the sealing groove 33, the elastic stop spring abuts against the top-holding edge 49 to limit the backward movement of the sliding sleeve 40.

[0041] Referring to Figure 5 and Figure 6 , the inside of the control cavities 45 is provided with a pressure-holding plate 410 for compressing the stop spring 25, which is located in the control cavities 45 and perpendicular to the side surface of the male terminal 20. The side surface of the control cavities 45 is fixedly provided with two guide strips 411, which are both perpendicular to the side surface of the male terminal 20. The two guide strips 411 are provided with a guide sliding groove 412 for guiding the lifting and sliding of the pressure-holding plate 410, and the two ends of the pressure-holding plate 410 are respectively located in the two opposite guide sliding grooves 412. The outer surface of the sliding sleeve 40 is provided with a pressing portion 413, which constitutes the cavity wall of the control cavities 45 facing the side of the male terminal 20. The pressing portion 413 is elastically arranged. When the stop spring 25 abuts against the top-holding edge 49 to make the sliding sleeve 40 in the braking state, the surface of the pressing portion 413 abuts against one end of the surface of the pressure-holding plate 410 away from the male terminal 20 when the pressing portion 413 is pressed by fingers, the pressure-holding plate 410 abuts against the stop spring 25, and the stop spring 25 slides into the insertion sliding gap 47 along the sliding slope 48, thereby achieving the unlocking of the sliding sleeve 40.

[0042] The implementation principle of the present application is that when connecting the wire harness 10, first, the male terminal 20 is inserted into the female terminal 30. At this time, the elastic hook 31 on the female terminal 30 is hooked into the hooking groove 21 on the male terminal 20, limiting the separation of the male terminal 20 and the female terminal 30.

[0043] Then, the sliding sleeve 40 is slid towards the female terminal 30, so that the sealing ring piece 41 on the side of the female terminal 30 is inserted into the sealing groove 33 on the sealing seat 32, and the sliding sleeve 40 is continuously pushed to move. The sealing ring piece 41 is expanded due to the constraint of the shape of the arc-shaped groove 34, and the raised edge blocks the water droplets falling onto the sealing ring piece 41, increasing the water droplets flowing into the gap between the male terminal 20 and the female terminal 30 through the arc-shaped groove 34.

[0044] Before sliding the sliding sleeve 40, the brake spring 25 is in the sliding gap 47, and the brake spring 25 is in a pressed state. During the movement of the sliding sleeve 40, the brake spring 25 is separated from the sliding gap 47 through the sliding slope 48, and abuts against the top holding edge 49, thereby limiting the retreat of the sliding sleeve 40. At this time, the upper water baffle 43 and the lower water baffle 22 abut, so that the upper buckling edge 44 and the lower buckling edge 23 are buckled. The cooperation of the upper water baffle 43 and the lower water baffle 22 can block the water droplets between the side of the sliding sleeve 40 close to the wire harness 10 and the surface of the male terminal 20 in the water stopping cavity 42, thereby avoiding the water droplets falling into the connection between the male terminal 20 and the female terminal 30.

[0045] When unlocking the sliding sleeve 40, the pressing part 413 is pressed by the finger, so that the pressing part 413 is deformed, the pressing part 413 abuts against the edge of the pressing plate 410, and the other end of the pressing plate 410 abuts against the surface of the brake spring 25. With the movement of the pressing plate 410, the end of the brake spring 25 is gradually close to the side close to the male terminal 20, until the height of the brake spring 25 is less than the height of the sliding gap 47, the sliding sleeve 40 is slid, so that the sealing ring piece 41 is separated from the sealing groove 33. Then, the elastic hook 31 is separated from the hooking groove 21, and the male terminal 20 is separated from the female terminal 30.

[0046] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made on the structure, shape, principle of the present application should be covered in the protection scope of the present application.
