Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a waterproof connector. Background Technology

[0002] In routine electrical work, connectors are often used to connect two or more cables to extend cable length or increase the number of devices that can be connected, thereby enabling electrical connections and signal transmission between devices and components, components and cabinets, and systems and subsystems. Today, connectors are widely used in aerospace, military equipment, communications, computers, automobiles, industry, and home appliances.

[0003] With the widespread use of underwater electrical equipment and devices, a large number of connectors are needed to connect underwater electrical systems to surface terminal equipment or power sources. This necessitates that connectors possess excellent waterproofing to prevent water from entering the joint and causing short circuits or even burning out the equipment. Currently, conventional deep-water connectors use threaded connections between plugs and sockets, with waterproof gaskets on the plugs to block the external threads of the sockets, preventing water from entering the threads. However, during prolonged use, especially in deep-sea environments, the threaded end faces inevitably corrode, weakening the seal between the waterproof gasket and the socket end faces. Simultaneously, under pressure, water can seep into the connector through gaps between the waterproof gasket and the socket, as well as through gaps in the threads. Therefore, the reliability of the seal needs further improvement. Utility Model Content

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] This utility model provides a waterproof connector, including a plug assembly and a socket assembly. The plug assembly has a first insertion port at the center of one end, and the socket assembly has a second insertion port at the center of one end. The first insertion port and the second insertion port are plugged into each other. The plug assembly has an annular insertion groove around the first insertion port at the center of one end, and a first sealing ring is provided at the bottom of the insertion groove. The socket assembly has an annular insertion part around the second insertion port at the center of one end. The insertion part and the insertion groove are connected by threads. The insertion part abuts against the first sealing ring, and the inner sidewall of the insertion groove abuts against the end of the socket assembly.

[0006] The beneficial effects of this utility model are:

[0007] This invention achieves a threaded seal by connecting the plug part and the plug groove via a threaded connection; a slit seal is formed on the unthreaded side of the plug part; the plug part abuts against the first sealing ring, forming a first-level planar seal; and the inner wall end of the plug groove abuts against the end of the socket assembly, forming a second-level planar seal. Thus, within the limited insertion space of the plug assembly and socket assembly, a triple forced sealing structure and a single passive slit seal structure are formed, significantly improving the sealing effect and achieving an IP68 waterproof rating, suitable for long-term use in deep-sea environments. Furthermore, the deformable nature of the first sealing ring ensures the sealing of the plug part's end while allowing the inner wall end of the plug groove to continue advancing and abut against the end of the socket assembly, promoting the formation of the second-level planar seal.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the plug assembly includes a cylindrical plug housing, a plug base fixed inside the plug housing, and multiple first pins fixed inside the plug base; a locking sleeve is fitted on the plug housing, a gap is formed between the inner side wall of one end of the locking sleeve and the outer side wall of one end of the plug housing to form the insertion groove, and the other end of the locking sleeve is connected to the middle of the plug housing.

[0010] The modular design facilitates the pre-processing of the plug housing and locking sleeve before assembly, making processing convenient and cost-effective. After installation, one end of the plug housing and its inner circumference plug base abut against the end of the socket assembly, forming an end face seal and improving sealing performance. One end of the plug housing, one end of the plug base, and the first pin form the first insertion port. During insertion, the pin is supported by the plug base on all sides, ensuring good stability, preventing plastic deformation of the pin, ensuring reliable insertion, and extending service life.

[0011] Furthermore, the outer wall of the middle part of the plug housing is provided with a first step, the first sealing ring is located at one end of the first step, and the inner wall of the other end of the locking sleeve is rotatably connected to the outer periphery of the first step; at the same time, the threaded connection with the plug part can be completed simply by rotating the locking sleeve, which is convenient for installation.

[0012] The seam between the other end of the locking sleeve and the plug housing is located outside the first sealing ring, which improves the sealing effect.

[0013] Furthermore, a retaining ring is also fitted on the plug housing, the retaining ring is located at the other end of the first step, and the retaining ring is partially embedded in the inner wall of the other end of the locking sleeve; a second step is also provided in the middle of the locking sleeve, and the end face of the second step contacts one end of the first step.

[0014] Easy to install, it achieves a fixed connection between the plug housing and the locking sleeve; the retaining ring restricts the movement of the locking sleeve, ensuring that the end face of the stepped structure in the middle of the locking sleeve contacts the end face of the first step, achieving end face sealing and improving the sealing effect.

[0015] Furthermore, a tail cover is fixedly fitted to the other end of the plug housing. The tail cover is filled with a first sealing filler. The first sealing filler extends into the plug housing and contacts the plug base. The first sealing filler contains multiple first wire cores, which are connected one-to-one with multiple first pins.

[0016] The tail cover and the first sealing filler seal the first wire core and its joint with the first pin, improving the reliability of waterproofing. At the same time, the tail cover can be removed to disassemble and maintain the first wire core, the first pin and other components, resulting in low maintenance costs.

[0017] Furthermore, the other end of the plug housing is provided with an external thread, and one end of the tail cover is connected to the external thread of the other end of the plug housing through an internal thread.

[0018] A threaded seal is formed between the tail cover and the plug housing, making disassembly and assembly convenient and providing a good sealing effect.

[0019] Furthermore, the inner wall of the end of the tail cover is provided with a second sealing ring, which is fitted onto the plug housing; the middle part of the plug housing is provided with a third step, and the end face of the tail cover abuts against the end face of the third step.

[0020] The tail cover and the plug housing form an end face seal and a sealing ring seal, which improves the sealing and waterproofing effect.

[0021] Furthermore, the socket assembly includes a cylindrical socket housing, a socket base fixed inside the socket housing, and multiple second pins fixed inside the socket base; one end of the socket housing protrudes from the socket base and forms the plug-in portion, and one end of the second pin protrudes from the socket base and is located inside the plug-in portion.

[0022] One end of the second pin protrudes from the base of the socket to form a second plug port, which facilitates connection with the first plug port. At the same time, the gap inside one end of the socket housing can be used to accommodate the solid of the first plug port, avoiding structural interference and improving sealing.

[0023] Furthermore, a second sealing filler is fixed inside the other end of the socket housing, and the second sealing filler is in contact with the socket base; multiple second wire cores are also fixed inside the second sealing filler, and the multiple second wire cores are connected to multiple second pins one by one.

[0024] The second sealing filler seals the second wire core and its connection with the second pin, improving the reliability of waterproofing.

[0025] Furthermore, the outer ring wall of the insertion groove is provided with an internal thread, and the outer side of the insertion part is connected to the internal thread of the outer ring wall of the insertion groove through an external thread.

[0026] The threaded seal on the outer side of the plug is set as the first-level forced seal, which improves the strength of the first-level seal. At the same time, it prevents the unthreaded side slit of the plug from being exposed to the water medium, so that it can fully play the auxiliary sealing role. Attached Figure Description

Detailed Implementation

[0034] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0035] This utility model refers to Figure 1-5 .

[0036] This utility model provides a waterproof connector, including a plug assembly 1 and a socket assembly 2. The plug assembly 1 has a first insertion port at the middle of one end, and the socket assembly 2 has a second insertion port at the middle of one end. The first insertion port and the second insertion port are plugged into each other. The plug assembly 1 has an annular insertion groove 3 around the first insertion port at the middle of one end, and a first sealing ring 4 is provided at the bottom of the insertion groove 3. The socket assembly 2 has an annular insertion part 5 around the second insertion port at the middle of one end. The insertion part 5 is threadedly connected to the insertion groove 3. The insertion part 5 abuts against the first sealing ring 4, and the inner sidewall end of the insertion groove 3 abuts against the end of the socket assembly 2.

[0037] The principle of the waterproof connector of this utility model is as follows:

[0038] During installation, the first and second plug-in ports are plugged in, and the plug-in part 5 is inserted into the plug-in groove 3 and connected by threads. After installation, the threaded side of the plug-in part 5 forms a threaded seal, and the unthreaded side forms a narrow gap. The air in the narrow gap helps maintain the pressure balance inside and outside the connector while increasing the resistance to external water seepage, thus achieving a slit seal effect. At the same time, the plug-in part 5 abuts against the first sealing ring 4 to form a planar seal, and the inner wall end of the plug-in groove 3 abuts against the end of the socket assembly 2 to form a planar seal. The threaded seal and planar seal are forced sealing structures that forcefully eliminate leakage channels, while the slit seal is a passive sealing structure that increases the resistance to water seepage, thereby achieving an auxiliary sealing effect. Thus, this utility model forms a triple forced sealing structure of threaded connection and two planar seals within a limited space, while also forming a passive slit seal structure, greatly improving the sealing effect and making it suitable for long-term use in deep-sea environments.

[0039] In summary, this invention forms a threaded seal by connecting the plug part 5 to the plug groove 3 via a threaded connection; a slit seal is formed on the unthreaded side of the plug part 5; the plug part 5 abuts against the first sealing ring 4, forming a first-level planar seal; and the inner wall end of the plug groove 3 abuts against the end of the socket assembly 2, forming a second-level planar seal. Thus, a triple forced sealing structure and a single passive slit seal structure are formed within the limited insertion space between the plug assembly 1 and the socket assembly 2, greatly improving the sealing effect and achieving an IP68 waterproof rating, making it suitable for long-term use in deep-sea environments. Furthermore, the deformable nature of the first sealing ring 4 ensures the sealing of the end of the plug part 5 while allowing the inner wall end of the plug groove 3 to continue advancing and abut against the end of the socket assembly 2, promoting the formation of the second-level planar seal.

[0040] Furthermore, such as Figure 2-3 As shown: The plug assembly 1 includes a cylindrical plug housing 11, a plug base 12 fixed inside the plug housing 11, and multiple first pins 13 fixed inside the plug base 12; a locking sleeve 14 is fitted on the plug housing 11, and there is a gap between the inner side wall of one end of the locking sleeve 14 and the outer side wall of one end of the plug housing 11 to form the insertion groove 3, and the other end of the locking sleeve 14 is connected to the middle of the plug housing 11.

[0041] Preferably, one end of the locking sleeve 14 has an internal thread on its inner sidewall, and the outer sidewall of the insertion part 5 is connected to the internal thread of the inner sidewall of the locking sleeve 14 via an external thread. The other end of the locking sleeve 14 is fixedly or rotatably connected to the middle of the plug housing 11.

[0042] The modular design facilitates the pre-processing of the plug housing 11 and the locking sleeve 14 before assembly, making processing convenient and cost-effective. After installation, one end of the plug housing 11 and its inner circumference plug base 12 abut against the end of the socket assembly 2, forming an end face seal and improving sealing performance. One end of the plug housing 11, one end of the plug base 12, and the first pin 13 form the first insertion port. During insertion, the pin is supported by the plug base 12 on all sides, resulting in good stability, avoiding plastic deformation of the pin, reliable insertion, and long service life.

[0043] Furthermore, the outer wall of the middle part of the plug housing 11 is provided with a first step 16, the first sealing ring 4 is located at one end of the first step 16, and the inner wall of the other end of the locking sleeve 14 is rotatably connected to the outer periphery of the first step 16.

[0044] The seam between the other end of the locking sleeve 14 and the plug housing 11 is located outside the first sealing ring 4, which improves the sealing effect; at the same time, the threaded connection with the plug part 5 can be completed simply by rotating the locking sleeve 14, making installation convenient.

[0045] Furthermore, a retaining ring 17 is also fitted on the plug housing 11. The retaining ring 17 is located at the other end of the first step 16, and the retaining ring 17 is partially embedded in the inner side wall of the other end of the locking sleeve 14. The locking sleeve 14 is also provided with a second step in the middle, and the end face of the second step is in contact with one end of the first step 16.

[0046] Preferably, the retaining ring 17 is an open ring, and the inner wall of the other end of the locking sleeve 14 is provided with an annular groove into which the retaining ring 17 can be inserted. During installation, the retaining ring 17 is opened wide along its opening and fitted into the plug housing 11 along its large diameter section. Then, the retaining ring 17 is compressed along its opening until it is flush with the outer periphery of the first step 16. The other end of the locking sleeve 14 is then fitted onto the retaining ring 17 and the first step 16, and the retaining ring 17 is abutted and fixed to the other end of the first step 16. The locking sleeve 14 continues to move toward the other end of the plug housing 11 until the annular groove moves to the position of the retaining ring 17. The retaining ring 17 recovers under its own elasticity and enters the annular groove, thus completing the locking and fixing of the locking sleeve 14.

[0047] Easy to install, it achieves a fixed connection between the plug housing 11 and the locking sleeve 14; the movement of the locking sleeve 14 is restricted by the retaining ring 17, which ensures that the end face of the stepped structure in the middle of the locking sleeve 14 contacts the end face of the first step 16, thus achieving end face sealing and improving the sealing effect.

[0048] Furthermore, a tail cover 15 is fixedly fitted on the other end of the plug housing 11. The tail cover 15 is filled with a first sealing filler 18. The first sealing filler 18 extends into the plug housing 11 and contacts the plug base 12. The first sealing filler 18 is provided with multiple first wire cores 19, and the multiple first wire cores 19 are connected to multiple first pins 13 in a one-to-one correspondence.

[0049] Preferably, the first sealing filler 18 is 2850CT adhesive.

[0050] The tail cover 15 and the first sealing filler 18 seal the first wire core 19 and its joint with the first pin 13, improving the reliability of waterproofing. At the same time, the tail cover 15 can be removed to disassemble and maintain the first wire core 19, the first pin 13 and other components, resulting in low maintenance costs.

[0051] Furthermore, the other end of the plug housing 11 is provided with an external thread, and one end of the tail cover 15 is connected to the external thread of the other end of the plug housing 11 through an internal thread.

[0052] A threaded seal is formed between the tail cover 15 and the plug housing 11, which makes disassembly and assembly convenient and provides a good sealing effect.

[0053] Furthermore, the inner wall of the end of the tail cover 15 is provided with a second sealing ring 111, which is fitted onto the plug housing 11; the middle part of the plug housing 11 is provided with a third step 110, and the end face of the tail cover 15 abuts against the end face of the third step 110.

[0054] Preferably, there is a gap between the first step 16 and the third step 110, and the retaining ring 17 is located within the gap between the first step 16 and the third step 110.

[0055] The tail cover 15 and the plug housing 11 form an end face seal and a sealing ring seal, which improves the sealing and waterproofing effect.

[0056] Furthermore, such as Figure 4-5 As shown: The socket assembly 2 includes a cylindrical socket housing 21, a socket base 22 is fixed inside the socket housing 21, and multiple second pins 23 are fixed inside the socket base 22; one end of the socket housing 21 protrudes from the socket base 22 and forms the plug-in portion 5, and one end of the second pin 23 protrudes from the socket base 22 and is located inside the plug-in portion 5.

[0057] Preferably, one end of the socket housing 21 is provided with an external thread, and the outer ring wall of the insertion groove 3 is provided with an internal thread. One end of the socket housing 21 is connected to the internal thread of the insertion groove 3 through the external thread; specifically, one end of the socket housing 21 is connected to the internal thread of the inner side wall of the lock sleeve 14 through the external thread.

[0058] One end of the second pin 23 protrudes from the socket base 22 to form a second plug port, which facilitates connection with the first plug port. At the same time, the gap inside one end of the socket housing 21 can be used to accommodate the solid of the first plug port, avoiding structural interference and improving sealing.

[0059] Furthermore, a second sealing filler 24 is fixed inside the other end of the socket housing 21, and the second sealing filler 24 contacts the socket base 22; multiple second wire cores 25 are also fixed inside the second sealing filler 24, and the multiple second wire cores 25 are connected to multiple second pins 23 in a one-to-one correspondence.

[0060] Preferably, the second sealing filler 24 is 2850CT adhesive.

[0061] The second sealing filler 24 seals the second wire core 25 and its joint with the second pin 23, thereby improving the reliability of waterproofing.

[0062] Furthermore, the outer ring wall of the insertion groove 3 is provided with an internal thread, and the outer side of the insertion part 5 is connected to the internal thread of the outer ring wall of the insertion groove 3 through the external thread.

[0063] Note: The insertion groove 3 is an annular groove, with the side wall with the larger diameter being the outer annular wall and the side wall with the smaller diameter being the inner annular wall.

[0064] The threaded seal on the outer side of the plug part 5 is set as the first-level forced seal, which improves the strength of the first-level seal. At the same time, it prevents the unthreaded side slit of the plug part 5 from being exposed to the water medium, so that it can fully play the auxiliary sealing role.
