In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] The utility model will be further described below in conjunction with the accompanying drawings.

[0018] like Figure 1-4 As shown, a waterproof connector includes a female socket housing 1, a sealing ring 2, a female contact 12, a male contact 13, a male socket housing 3 and a waterproof component.

[0019] Specifically, a sealing ring 2 is provided on the female socket housing 1. When the male contact 13 is inserted into the female contact 12, the sealing ring 2 can play a certain waterproof role to prevent water vapor or water from entering the gap between the female socket housing 1 and the male socket housing 3; a female contact 12 is provided in the female socket housing 1, and the female contact 12 is plugged with a male contact 13, and the male contact 13 is connected to the male socket housing 3. The sealing ring 2 and one end of the male socket housing 3 are tightly attached, and the waterproof component is installed on the female socket housing 1 to protect the connection between the female socket housing 1 and the male socket housing 3.

[0020] Specifically, the waterproof assembly includes a first support plate 4, two second support plates 5, multiple guide rods 6, multiple springs 7, a waterproof plate 8 and a sealing cushion 9. The first support plate 4 is connected to the outer wall of the female socket housing 1, and multiple guide rods 6 are slidably connected to the first support plate 4. The multiple guide rods 6 play a limiting role, so that the waterproof plate 8 can only make a linear motion along the direction of the guide rods 6; one end of the guide rod 6 is connected to the waterproof plate 8, and the other end of the guide rod 6 is connected to the corresponding second support plate 5. Each guide rod 6 is sleeved with a spring 7, one end of each spring 7 is connected to the first support plate 4, and the other end of each spring 7 is connected to the corresponding second support plate 5. The two second support plates 5 are slidably connected to the outer wall of the female socket housing 1, and a sealing cushion 9 is provided on the inner wall of the waterproof plate 8. The sealing cushion 9 is tightly attached to the outer wall of the female socket housing 1. Under the action of the elastic force of the multiple springs 7, the waterproof plate 8 will move to the gap between the female socket housing 1 and the male socket housing 3, thereby performing secondary waterproof protection on the gap between the female socket housing 1 and the male socket housing 3.

[0021] Specifically, a plurality of third support plates 10 are provided on the waterproof plate 8, each of which is provided with a threaded through hole, and two threaded through holes close to the female socket shell 1 are internally threadedly connected to a limit rod 11, and an upper portion of the limit rod 11 is provided with an external thread, and a limit hole 14 is provided on the female socket shell 1 and the male socket shell 3, and the limit rod 11 is inserted into the corresponding limit hole 14, and a rotating handle 15 is connected to one end of the limit rod 11, and the rotating handle 15 can facilitate the rotation of the limit rod 11, so as to install or remove the limit rod 11 from the limit hole 14, and by fixing the two limit rods 11 to the two limit holes 14 close to the female socket shell 1, it is possible to prevent the waterproof plate 8 from being affected by the elastic force of the plurality of springs 7 and moving to the interface of the female socket shell 1, thereby affecting the plugging of the male contact 13 and the female contact 12.

[0022] Specifically, the cross-sections of the female socket shell 1 and the male socket shell 3 are the same size, which can ensure that the waterproof board 8 can cover the gap between the female socket shell 1 and the male socket shell 3; the waterproof board 8 is made of stainless steel material, and the waterproof board 8 has good corrosion resistance and can effectively extend the service life of the device; the sealing ring 2 and the sealing cushion 9 are both made of rubber material.

[0023] Working principle: After the female socket shell 1 and the male socket shell 3 are plugged in, the male socket shell 3 is close to the sealing ring 2 of the female socket shell 1. At this time, the two rotating handles 15 are rotated in sequence to take out the two limit rods 11 from the two limit holes 14 close to the female socket shell 1. At this time, the elastic force generated by the multiple springs 7 originally in the expanded state moves the waterproof plate 8 until the waterproof plate 8 completely covers the sealing ring 2. At this time, the multiple springs 7 are in a balanced state, and then the two limit rods 11 are fixed in the two limit holes 14 close to the male socket shell 3. This can increase the tightness of the connection between the female socket shell 1 and the male socket shell 3, prevent the female socket shell 1 and the male socket shell 3 from detaching, and cause water vapor to enter the electrical parts.

[0024] The above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
