Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0029] Example 1

[0030] Reference Figures 1-5 A watertight connector includes: a male connector 100, one end of which is recessed to form a recessed area, and a pin 102 is installed in the recessed area; a protective seat 400, which is disposed in the recessed area and located at one end of the pin 102, and the protective seat 400 is used to seal the recessed area to prevent water from entering, and the protective seat 400 has a through hole 401 for the pin 102 to pass through; and a second sealing head 402, which is disposed in the through hole 401 and is used to seal the through hole 401. When the protective seat 400 moves in the recessed area, the pin 102 passes through the through hole 401 and squeezes the second sealing head 402, causing the second sealing head 402 to move away from the pin 102.

[0031] In this embodiment, the male connector 100 is part of a watertight connector, with one end recessed to form a recessed area. This recessed area provides installation space for components such as the pin head 102 and the protective seat 400. The pin head 102 is installed in the recessed area for electrical connection with the connector 300 of the female connector 200. The protective seat 400 seals the recessed area to prevent water from entering, thus protecting the pin head 102 from water corrosion. Only when the connector 300 on the female connector 200 is inserted into the recessed area will the connector 300 press against the protective seat 400, causing the protective seat 400 to move. The second sealing head 402 is used to seal the through hole 401. When the protective seat 400 moves within the recessed area, the pin head 102 passes through the through hole 401 and presses against the second sealing head 402, causing the second sealing head 402 to move away from the pin head 102, ensuring that the pin head 102 can pass through smoothly.

[0032] The protective seat 400 includes: a second groove 403 formed on the inner wall of the through hole 401, the second groove 403 being annular; a second sealing head 402 installed in the second groove 403, and the number of second sealing heads 402 being at least three; a second elastic member 404, one end of which is installed on the inner wall of the second groove 403, and the other end of which is connected to the second sealing head 402; and a sealing ring 405 installed on the outer ring of the protective seat 400, the sealing ring 405 being located between the protective seat 400 and the recessed area, and the number of sealing rings 405 being at least two.

[0033] The aforementioned sealing ring 405 enhances the sealing effect between the protective seat 400 and the recessed area, preventing water from entering through the gap between the protective seat 400 and the recessed area. The function of the second elastic element 404 is to provide support and reset for the second sealing head 402. The second elastic element 404 can be a sheet or a spring.

[0034] It also includes: a female connector 200, which is connected to the male connector 100; a connector 300, which is installed inside the female connector 200 and is used to be inserted into the recessed area of ​​the male connector 100. One end of the connector 300 is provided with a pin slot 301, and a pin head 102 is installed in the pin slot 301.

[0035] The aforementioned female connector 200 connects to the male connector 100 and forms another part of the watertight connector. The female connector 200 can be either an SMC14Z29ZM1 or an SMC08Z29ZM1 watertight connector. The female connector 200 contains a connector 300 for mating with the pin 102 of the male connector 100. The pin 102 is installed in the pin slot 301 to achieve electrical connection.

[0036] The connector 300 includes: a first groove 302 formed on the inner wall of the pin slot 301, the first groove 302 being annular; a first sealing head 303 installed in the first groove 302, and the number of first sealing heads 303 being at least three, the first sealing heads 303 being used to seal the pin slot 301; and a first elastic member 304, one end of which is connected to the inner wall of the first groove 302, and the other end of which is connected to the first sealing head 303.

[0037] The first groove 302 provides an installation position for the first sealing head 303 and the first elastic element 304. The first sealing head 303 is used to seal the pin groove 301 to prevent water from entering the inside of the pin groove 301 and to protect the electrical connection between the pin head 102 and the connector 300. When the male connector 100 is connected to the female connector 200, the pin head 102 will squeeze the first sealing head 303 while being inserted into the pin groove 301. The first sealing head 303 is squeezed away from the pin head 102. The first elastic element 304 provides support and reset for the first sealing head 303. The first elastic element 304 can be a sheet or a spring.

[0038] The male connector 100 includes a connecting sleeve 101, which is installed on the pin head 102. The connecting sleeve 101 is connected to the female connector 200 by threads. The connecting sleeve 101 can ensure a tight and reliable connection between the male connector 100 and the female connector 200, and also facilitates installation and disassembly.

[0039] During use, in the recessed area of ​​the male connector 100, the protective seat 400, relying on at least two sealing rings 405 installed on the outer ring, tightly fits against the recessed area, sealing it and effectively preventing water from entering. The second sealing head 402, supported by the second elastic element 404, makes tight contact with each other, sealing the through hole 401. The first sealing head 303, under the action of the first elastic element 304, makes tight contact with each other, sealing the pin groove 301. At this time, all key parts of the watertight connector are in a waterproof and sealed state, and the pin head 102 is well protected. When it is necessary to connect the male connector 100 and the female connector 200, the female connector 200 is moved closer to the male connector 100 to prepare for the docking operation. The connector 300 of the female connector 200 is gradually inserted into the recessed area of ​​the male connector 100. During this process, the connector 300 presses against the protective seat 400, causing the protective seat 400 to... As the protective seat 400 moves within the recess, the pin 102 passes through the through hole 401 on the protective seat 400. During this process, the pin 102 is squeezed, causing the second sealing head 402 to move in the second groove 403 in a direction away from the pin 102, thus allowing the pin 102 to pass smoothly through the through hole 401. At the same time, the pin 102 is inserted into the pin groove 301 opened at one end of the connector 300. The pin 102 squeezes the first sealing head 303 in the pin groove 301, causing the first sealing head 303 to move in the first groove 302 in a direction away from the pin 102. By rotating the connecting sleeve 101, the male connector 100 is tightly connected to the female connector 200 using threads, further enhancing the sealing and reliability of the connection between the male connector 100 and the female connector 200, completing the connection operation of the entire watertight connector, and achieving a stable underwater electrical connection.

[0040] Example 2

[0041] The difference between this embodiment and Embodiment 1 is that, referring to... Figure 6 A sealing element 103 is installed on the inner wall of the male head 100. The sealing element 103 is circular.

[0042] In summary, compared with existing technologies, it has the following beneficial effects:

[0043] By providing a protective seat 400 in the recessed area of ​​the male connector 100, water is effectively prevented from entering through the gap between the protective seat 400 and the recessed area, providing a relatively enclosed space for the pin head 102 and reducing the contact area between the pin head 102 and water. The second sealing head 402 inside the protective seat 400 seals the through hole 401, effectively preventing the surface oxidation and corrosion of the pin head 102 caused by prolonged contact with water.

[0044] By using the first sealing head 303 provided inside the connector 300, the first sealing head 303 seals the pin slot 301 in the non-connected state, preventing water from entering, improving the connection reliability of the watertight connector, and ensuring the stability of the electrical connection of underwater equipment.
