[0002] A connector is a component used to connect two or more electrical devices or circuits, enabling the transmission of signals or electricity between them. The main function of a connector is to bridge gaps in a circuit or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function. They are widely used in various electronic devices, from simple household appliances to complex communication systems and computer networks.

[0003] Existing connectors have poor waterproof performance, and water and / or moisture can easily enter the connector from the connector interface, thereby affecting the connector's performance and reducing its service life. Summary of the Invention

[0004] The main objective of this application is to provide a waterproof connector, which aims to solve the problem that water and / or moisture can easily enter the interface of existing connectors, affecting the service life of the connector.

[0005] To achieve the above objectives, this application provides a waterproof connector, comprising: a plug assembly and a socket assembly. The plug assembly includes: a plug body and a plurality of pins, wherein the plurality of pins are disposed on the side of the plug body that is adapted to the socket assembly. The socket assembly includes: a mating portion, a sealing gasket, and a connector. When the plug assembly and the socket assembly are mated, the pins are inserted into the mating portion, and a sealing gasket adaptation cavity is formed on the side of the mating portion near the pins. The sealing gasket is disposed within the sealing gasket adaptation cavity and has a plurality of pin adaptation holes, each corresponding to a pin. The connector is disposed within the mating portion and abuts against the sealing gasket. The connector has a plurality of pin holes, each corresponding to a pin adaptation hole, and the pin holes are coaxial with their corresponding pin adaptation holes.

[0006] Optionally, the pin includes a sealing section and a conductive section, wherein the sealing section is interference-fitted into the pin adapter hole; the conductive section is disposed at the end of the sealing section and fits into the pin hole.

[0007] Optionally, the diameter of the sealing section is larger than the diameter of the conducting section.

[0008] Optionally, a protrusion is provided in the pin adapter hole, and the section of the conductive section near the sealing section is interference-fitted with the protrusion.

[0009] Optionally, each of the pins is provided with a sealing cylinder on its exterior, the diameter of which is larger than the diameter of the pin.

[0010] Optionally, the length of the sealing cylinder is less than the length of the pin; the sealing gasket has a mating hole, and when the plug assembly and the socket assembly are mated, the sealing cylinder is mated in the mating hole.

[0011] Optionally, the plug body has a groove on the side facing the insertion part, and a sealing structure is provided in the groove.

[0012] Optionally, the sealing structure is made of silicone.

[0013] Optionally, the plug body is also provided with symmetrical connecting holes, and a locking rod is provided in the connecting hole. The locking rod is threadedly engaged with the plug body. When the plug assembly and the socket assembly are engaged, the locking rod is threadedly engaged with the socket assembly.

[0014] Optionally, a retaining ring is provided on the locking rod, and a sealing ring is provided between the retaining ring and the plug body.

[0015] This application provides a waterproof connector in which the plug assembly and socket assembly achieve electrical or signal connection through the insertion of pins and mating parts. Simultaneously, a sealing gasket tightly wraps around the pins through pin adapter holes, effectively preventing moisture from seeping in through the gap between the pins and mating parts, thus ensuring the waterproof performance of the connector. The connector not only provides stable support for the sealing gasket but also further ensures precise alignment between the pins and mating parts through its pin holes, improving the stability and reliability of the connection. In this embodiment, the protrusion within the pin adapter hole forms an interference fit with a section of the conductive section near the sealing mating section. This structural design further enhances the sealing performance between the pin and the pin adapter hole. The presence of the protrusion generates additional friction between the conductive section and the protrusion when the pin is inserted into the pin adapter hole, thereby ensuring tight contact between the pin and the pin adapter hole. This effectively prevents moisture and humidity from entering the connector through the gap between the pin and the pin adapter hole, improving the overall waterproof performance of the waterproof connector.

[0025] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Figure 1 This is a schematic diagram of the structure of a waterproof connector provided in an embodiment of this application; Figure 2 for Figure 1 Another structural schematic diagram of the plug assembly; Figure 3 for Figure 2 A structural diagram from another perspective; Figure 4 for Figure 3 A schematic diagram showing the removal of the sealing structure; Figure 5 for Figure 1 Another structural diagram of the socket assembly; Figure 6 for Figure 1 A cross-sectional view of the center socket assembly; Figure 7 for Figure 6 A schematic diagram of the structure with an added sealing cylinder.

[0027] Please see Figures 1 to 7 This application provides a waterproof connector, which may include a plug assembly 1 and a socket assembly 2. The plug assembly 1 may include a plug body 101 and a plurality of pins 102, wherein the plurality of pins 102 are disposed on the side of the plug body 101 that mates with the socket assembly 2. The socket assembly 2 may include a mating portion 201, a sealing gasket 202, and a connector 204. When the plug assembly 1 and the socket assembly 2 are mated, the pins 102 are inserted into the mating portion 201. A sealing gasket adapter cavity is provided on the side of the connector 201 near the pin 102; the sealing gasket 202 is disposed in the sealing gasket adapter cavity, and a plurality of pin adapter holes 203 are provided on the sealing gasket 202, each corresponding to a pin 102; the connector 204 is disposed in the connector 201 and abuts against the sealing gasket 202, and a plurality of pin holes 205 are provided on the connector 204, each corresponding to a pin adapter hole 203, and the pin holes 205 and the corresponding pin adapter holes 203 are coaxial.

[0028] In this embodiment, the plug assembly 1 and the socket assembly 2 achieve electrical or signal connection through the insertion of the pin 102 into the connector 201. Simultaneously, the sealing gasket 202 tightly wraps around the pin 102 through its pin adapter hole 203, effectively preventing moisture from seeping in through the gap between the pin 102 and the connector 201, thus ensuring the waterproof performance of the waterproof connector. The connector 204 not only provides stable support for the sealing gasket 202 but also further ensures precise alignment between the pin 102 and the connector 201 through its pin hole 205, improving the stability and reliability of the connection.

[0029] Furthermore, the connector 204 is made of metal, such as iron or copper. Using a metal material for the connector 204 ensures good conductivity and does not affect signal or power transmission. Simultaneously, when the pin 102 is inserted into the pin adapter hole 203, the end of the pin 102 that mates with the connector 204 fits tightly against the connector 204, ensuring stable conductivity and signal transmission performance.

[0030] It should be noted that the sealing gasket 202 is made of rubber. Making the sealing gasket 202 of rubber ensures that the rubber material has a certain degree of elasticity when the pin 102 is inserted into the connector 201, thereby guaranteeing good sealing performance. Moisture present between the pin 102 and the connector 201 will not seep in through the gap between them.

[0031] Please see Figure 6 , Figure 7In some possible implementations, the pin 102 may include a sealing mating section 103 and a conducting section 104, wherein the sealing mating section 103 is interference-fitted into the pin adapter hole 203; the conducting section 104 is disposed at the end of the sealing mating section 103 and is mated into the pin hole 205.

[0032] The sealing mating section 103 is designed to create a tight interference fit between the pin 102 and the pin adapter hole 203. This fit effectively prevents the intrusion of moisture and humidity, enhancing the waterproof performance of the waterproof connector. The conducting section 104 is responsible for establishing a stable electrical or signal connection between the pin 102 and the mating part 201, thereby ensuring accurate signal transmission.

[0033] It is worth mentioning that the length of the conductive section 104 is greater than the length of the sealing section 103. This design ensures that the conductive section 104 and the connector 204 have a larger contact area, thereby ensuring the stability of current or signal transmission.

[0034] Furthermore, the sealing gasket 202 and the connector 204 have the same thickness within the insertion portion 201. This design ensures that the sealing gasket 202 and connector 204 are easy to manufacture, eliminating the need for different thicknesses and avoiding assembly problems or inadequate sealing due to varying thicknesses, which could easily cause the sealing gasket 202 to detach. Additionally, when the sealing gasket 202 and connector 204 have the same thickness, their fit with the inner wall of the insertion portion 201 is also better, effectively preventing moisture from seeping in from the side and improving overall waterproofing performance.

[0035] It should be further noted that the diameter of the sealing mating section 103 is slightly larger than the inner diameter of the pin adapter hole 203. This interference fit ensures a tight seal between the sealing mating section 103 and the pin adapter hole 203, further preventing moisture infiltration and enhancing waterproof performance. The shape and size of the conducting section 104 are adapted to the pin hole 205, allowing it to be smoothly inserted into the pin hole 205. This ensures a good electrical and mechanical connection between the pin 102 and the connector 204, guaranteeing stable signal and current transmission during normal operation of the waterproof connector.

[0036] Furthermore, in some possible implementations, the diameter of the sealing section 103 is larger than the diameter of the conducting section 104.

[0037] Specifically, this diameter difference design allows the sealing section 103 to better form a tight interference fit with the pin adapter hole 203, enhancing sealing performance and effectively preventing the intrusion of moisture and humidity. On the other hand, the relatively small diameter of the conducting section 104 ensures good fit with the pin hole 205 to achieve electrical and signal connections while reducing material usage and lowering costs during mass production.

[0038] Please see Figure 6 , Figure 7 In some possible implementations, a protrusion 206 is provided in the pin adapter hole 203, and the section of the conducting section 104 near the sealing section 103 is interference-fitted with the protrusion 206.

[0039] In this embodiment, the protrusion 206 provided in the pin adapter hole 203 forms an interference fit with a section of the conductive section 104 near the sealing mating section 103. This structural design further enhances the sealing performance between the pin 102 and the pin adapter hole 203. The presence of the protrusion 206 generates additional friction between the conductive section 104 and the protrusion 206 when the pin 102 is inserted into the pin adapter hole 203, thereby ensuring tight contact between the pin 102 and the pin adapter hole 203. This effectively prevents moisture and humidity from entering the connector through the gap between the pin and the pin adapter hole, improving the overall waterproof performance of the waterproof connector.

[0040] The cross-sectional shape of the protrusion 206 can be semi-circular, rectangular, or triangular. The specific shape of the protrusion 206 can be set according to the specific application scenario. It is sufficient that the protrusion 206 abuts against the conductive section 104 to form a good sealing effect. Furthermore, the number of protrusions 206 can also be set according to the specific application scenario, as long as external moisture cannot enter the connector.

[0041] Please see Figure 3 , Figure 7 In some possible implementations, each pin 102 is provided with a sealing cylinder 3 on its outside, and the diameter of the sealing cylinder 3 is larger than the diameter of the pin 102.

[0042] The sealing cylinder 3 provides an additional protective layer for the pin 102. When the plug assembly 1 mates with the socket assembly 2, the sealing cylinder 3 covers a portion of the pin 102, reducing the possibility of moisture directly contacting the pin 102. Simultaneously, because the aperture of the sealing cylinder 3 is larger than the diameter of the pin 102, it facilitates smooth insertion of the pin 102, and prevents damage to the sealing cylinder 3 or the pin 102 due to size issues during insertion, ensuring smooth assembly and effective sealing. This design improves waterproof performance while also facilitating connector assembly and maintenance.

[0043] In practical use, the length of the sealing cylinder 3 is slightly shorter than the length of the sealing gasket 202, making the sealing gasket 202 a single, integrated structure. This simplifies the assembly process when the sealing gasket 202 is installed as a separate unit. Furthermore, when the plug assembly 1 and the socket assembly 2 mate, the sealing cylinder 3 can fully enter the mating hole on the sealing gasket 202, forming a tighter seal. This effectively prevents moisture from seeping in from the contact surface between the pin 102 and the sealing gasket 202, further enhancing the protection level of the waterproof connector. In addition, the sealing cylinder 3 can be made of plastic. Plastic not only accommodates the slight deformation of the sealing gasket 202 when the pin 102 is inserted, but also maintains stable sealing performance over long-term use, making it less prone to seal failure due to aging or environmental factors.

[0044] Furthermore, in some possible implementations, the length of the sealing cylinder 3 is less than the length of the pin 102; the sealing gasket 202 has a mating hole 207, and when the plug assembly 1 and the socket assembly 2 are mated, the sealing cylinder 3 is mated in the mating hole 207.

[0045] In this embodiment, the design of the sealing cylinder 3 being shorter than the pin 201 ensures that when the pin 102 is inserted into the socket assembly 2, a portion of the pin 102 extends beyond the sealing cylinder 3 and directly contacts the pin hole 205 on the connector 204, thereby guaranteeing the reliability of the electrical or signal connection. Simultaneously, the mating hole 207 on the sealing gasket 202 is adapted to the sealing cylinder 3. When the plug assembly 1 and the socket assembly 2 are mated, the sealing cylinder 3 can be tightly inserted into the mating hole 207, forming another sealing barrier. This double-sealing design—the mating of the sealing cylinder 3 with the mating hole 207 and the sealing gasket 202 wrapping the pin 102—significantly improves the waterproof rating of the waterproof connector, effectively preventing the intrusion of moisture and humidity, and ensuring the stable operation of the connector in harsh environments.

[0046] Please see Figure 3 , Figure 4 In some possible implementations, the plug body 101 has a groove 105 on the side facing the insertion part 201, and a sealing structure 106 is provided in the groove 105.

[0047] Specifically, the groove 105 not only provides installation space for the sealing structure 106, but also, through its specific shape and depth, ensures that the sealing structure 106 is subjected to uniform compressive force when the plug body 101 mates with the socket assembly 2, thereby forming a stable and effective seal. The sealing structure 106 should have good elasticity and sealing performance, enabling it to tightly fit the contact surfaces of the plug body 101 and the socket assembly 2 when compressed, preventing the penetration of moisture and humidity. Furthermore, the design of the groove 105 also considers the ease of replacement and maintenance of the sealing structure 106, allowing for easy disassembly and replacement when needed, thus extending the service life of the waterproof connector.

[0048] Furthermore, in some possible implementations, the sealing structure 106 is made of silicone.

[0049] Silicone material possesses excellent elasticity, weather resistance, and chemical stability, maintaining stable performance over a wide temperature range. This allows the silicone sealing structure 106 to maintain its sealing effect even under extreme temperature changes, without losing elasticity or cracking due to thermal expansion and contraction. Simultaneously, silicone exhibits excellent barrier properties against moisture, oxygen, and other chemicals, effectively preventing these substances from entering the connector through the sealing structure 106, thus protecting the internal electronic components from damage. Furthermore, silicone material has good processing properties, allowing it to be easily manufactured into sealing structures 106 of various shapes and sizes to meet diverse design requirements.

[0050] Please see Figure 2 In some possible implementations, the plug body 101 is also provided with symmetrical connection holes, and a locking rod 107 is provided in the connection hole. The locking rod 107 is threadedly engaged with the plug body 101. When the plug assembly 1 and the socket assembly 2 are engaged, the locking rod 107 is threadedly engaged with the socket assembly 2.

[0051] In this embodiment, the symmetrically opened connection holes on the plug body 101 and the internally provided locking rod 107 provide a stable mechanical locking method for the connection between the plug assembly 1 and the socket assembly 2. The threaded engagement between the locking rod 107 and the plug body 101 allows the user to adjust its extension length by rotating the locking rod 107, thereby ensuring precise connection between the plug assembly 1 and the corresponding threaded structure on the socket assembly 2 when they are engaged. This threaded engagement not only provides strong connection force, ensuring the stability of the plug assembly 1 and the socket assembly 2 in the engaged state, but also facilitates quick assembly and disassembly operations, improving ease of use. Simultaneously, the design of the locking rod 107 should also consider waterproof performance; its connection points with the plug body 101 and the socket assembly 2 are waterproofed to prevent moisture from seeping into the connector, further enhancing the overall waterproof effect of the waterproof connector.

[0052] Please see Figure 2 In some possible implementations, a retaining ring 108 is provided on the locking rod 107, and a sealing ring is provided between the retaining ring 108 and the plug body 101.

[0053] Specifically, the retaining ring 108 on the locking rod 107 plays a crucial role in positioning and sealing. When the locking rod 107 is threaded into the socket assembly 2, the retaining ring 108 ensures that the locking rod 107 is not over-screwed, thus protecting the plug body 101 and the socket assembly 2 from damage. Simultaneously, the sealing ring between the retaining ring 108 and the plug body 101 further enhances the waterproof performance of the connection. This sealing ring is typically made of an elastic material, such as rubber or silicone, which forms a tight seal between the retaining ring 108 and the plug body 101, effectively preventing the penetration of moisture and humidity. This design not only improves the reliability of the waterproof connector but also extends its service life, enabling the connector to operate stably in various harsh environments.

[0054] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
