[0021] This utility model provides an appendix. Figures 1-3 In this embodiment of the present invention, a deep-sea connector includes a plug 10 and a socket 20. The socket 20 includes a socket housing 230 and a conductive structure 240 located inside the socket housing 230. The plug 10 includes a connecting portion 110, a main body portion 120, and a sealing portion 130. The connecting portion 110 includes a first connecting portion 111 and a second connecting portion 112. The first connecting portion 111 is cylindrical. The second connecting portion 112 has a pin assembly 30 inside and is nested inside the first connecting portion 111. One end of the main body portion 120 extends into and is nested inside the first connecting portion 111. The first connecting part 111 and the second connecting part 112 are threadedly connected, and the outer surfaces of the main body 120 and the second connecting part 112 are threadedly connected. The sealing part 130 is disposed at the other end of the main body 120. When the plug 10 and the socket 20 are engaged, the second connecting part 112 is inserted into and abuts against the inner surface of the socket housing 230. The first connecting part 111 and the outer surface of the socket housing 230 are threadedly connected. The pin assembly 30 and the conductive structure 240 are electrically connected. The interior of the socket housing 230 and the interior of the main body 120 are filled with sealant 50.

[0022] Specifically, this utility model relates to a deep-sea connector, including a plug 10 and a socket 20, which are connected and communicate with each other during use. The socket 20 includes a socket housing 230 and a conductive structure 240 inside the socket housing 230; the plug 10 includes three main components: a connecting part 110, a main body 120, and a sealing part 130. The connecting part 110 includes a first connecting part 111 and a second connecting part 112. The first connecting part 111 is cylindrical, and one end of the second connecting part 112 is nested inside the first connecting part 111. The second connecting part 112 also has a pin assembly 30 inside, and the pin assembly 30 is electrically connected to the conductive structure 240. When the plug 10 and socket 20 cooperate and work together, the second connecting part 112 is inserted into the socket housing 230, and the second connecting part 112 abuts against the inner wall of the socket housing 230; the first connecting part 111 is threadedly connected to the outer surface of the socket housing 230. This design makes the axes of the socket 20, the first connecting part 111, and the second connecting part 112 overlap, making the connection between the socket 20 and the plug 10 more secure and stable, and with a stronger load capacity. The socket housing 230 and the connecting part 110 can be made of corrosion-resistant materials such as TA2 titanium alloy, TC4 titanium alloy, or nickel-based alloy. The socket 20 can be directly installed on external devices, or a sleeve can be installed on one end of the socket 20 and then connected to the main body of the device, allowing for flexible use and making installation and disassembly more convenient. One end of the conductive structure 240 is electrically connected to the pin assembly 30, and the other end of the conductive structure 240 protrudes from the socket housing 230 for electrical connection to external devices.

[0023] One end of the main body 120 extends and is nested between the first connecting part 111 and the second connecting part 112, and this end of the main body 120 is also provided with threads and is threadedly connected to the outer surface of the second connecting part 112; the other end of the main body 120 is provided with a sealing part 130. The main body 120 can be made of corrosion-resistant materials such as TA2 titanium alloy, TC4 titanium alloy or nickel-based alloy, and has good pressure resistance.

[0024] The sealing part 130 is specifically a sealing gasket. The sealing gasket is located on the inner wall of one end of the main body 120. The sealing gasket is made of rubber or polytetrafluoroethylene. The sealing gasket can seal and prevent water seepage, and can also maintain the stability of the connector shape, preventing the sealing gasket from being stretched and deformed or torn.

[0025] Both the interior of the socket housing 230 and the interior of the main body 120 are filled with sealant 50. The sealant 50 is injected into the gaps inside the socket housing 230 and the main body 120, which can prevent water from seeping in from the surface of the socket housing 230 and the main body 120. The sealant 50 can fill the tiny gaps and openings between parts that are difficult to fit or are irregular in the mechanical seal, achieving all-round sealing and greatly improving the waterproof performance of the connector in deep water. In addition, the sealant 50 can also wrap the internal conductive structure 240 and the pin assembly 30, preventing the connector from becoming unstable in conductivity due to long-term water immersion.

[0026] In one embodiment, a first sealing ring 210 is provided on the outer surface of the socket housing 230, and a second sealing ring 220 is provided between the second connecting part 112 and the socket housing 230.

[0027] Specifically, the outer surface of the socket housing 230 is provided with a first sealing ring 210. When the socket 20 is connected to an external device, there will be some gaps. The first sealing ring 210 directly blocks the external medium from seeping in through the gaps, ensuring the stability of the electrical connection. Moreover, the first sealing ring 210 can also alleviate the vibration and impact during the insertion and removal of the socket 20 and other components, reducing wear. The second sealing ring 220 is used to fill the small gaps between the second connecting part 112 and the socket housing 230.

[0028] In one embodiment, there are two second sealing rings 220.

[0029] Specifically, the second connecting part 112 is inserted into the inner surface of the socket housing 230. The second connecting part 112 and the socket housing 230 are provided with two grooves, and each groove is provided with a second sealing ring 220. The double sealing ring design means that even if one of the second sealing rings 220 has a small gap due to wear, the other second sealing ring 220 can still prevent seawater from further seeping in, thus avoiding the risk of leakage caused by the failure of a single sealing ring.

[0030] In one embodiment, the deep-sea connector further includes a tail cap 60, which is threaded onto the outer periphery of the main body 120 at the end away from the connecting portion 110.

[0031] Specifically, one end of the main body 120 is connected to the connecting part 110, and the other end of the main body 120 is connected to the tail cap 60. The inner wall of the tail cap 60 is provided with internal threads, and the outer periphery of the end of the main body 120 is provided with external threads. The main body 120 and the tail cap 60 are axially fixed through threaded connection for sealing connection with the cable.

[0032] In one embodiment, a third sealing ring 121 is provided between the tail cap 60 and the main body 120.

[0033] Specifically, the tail cap 60 is made of metal, such as TC4 titanium alloy, stainless steel or nickel-copper alloy, etc. The tail cap 60 and the main body 120 are threaded together, and a third sealing ring 121 is provided at the connection between the tail cap 60 and the main body 120 to prevent liquid from entering.

[0034] In one embodiment, the plug housing 230, the connecting portion 110, the main body portion 120, and the tail cap 60 are all made of TC4 titanium alloy.

[0035] Specifically, compared to other metallic materials, TC4 titanium alloy has better corrosion resistance and toughness. In addition, TC4 titanium alloy has a low density and good stability in deep water environments.

[0036] In one embodiment, the pin assembly 30 includes multiple sets of pins 310 and an insulating core 40 surrounding the pins 310; the conductive structure 240 includes multiple sets of conductive posts 241 with sockets and an insulating core 40 surrounding the conductive posts 241.

[0037] Specifically, the pin assembly 30 is disposed within the second connecting part 112. The pin assembly 30 includes multiple sets of pins 310 and an insulating core 40 surrounding the pins 310. The conductive structure 240 includes conductive posts 241 and the insulating core 40. Each set of conductive posts 241 has a socket. The conductive posts 241 and the pins 310 are plugged into each other in a one-to-one correspondence. The pins 310 and the conductive posts 241 are made of conductive metals, such as copper or alloys, and are used to transmit electrical signals. The insulating core 40 is made of insulating material, which can effectively prevent short circuits, leakage and other problems, and ensure the safe and stable operation of the entire system.

[0038] In one embodiment, the end of the tail cap 60 away from the main body 120 is further provided with an adhesive layer 70.

[0039] Specifically, the tail cap 60 is threaded to the main body 120, and the end away from the main body 120 is also provided with an adhesive layer 70. When the adhesive is applied, the temperature rises and melts the third sealing ring 121, causing the third sealing ring 121 and the adhesive to fuse together, forming an integrated structure with stronger waterproof performance and impact resistance. The adhesive layer 70 extends to other parts connected to the connector, which can absorb bending stress, reduce wear, and also achieve a certain sealing effect, making it suitable for deep-water scenarios.

[0040] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
