Description

Technical Field

[0001] This invention relates to the field of underwater acoustic communication technology, specifically to a waterproof electrical connector for underwater communication equipment and an underwater telephone. Background Technology

[0002] The increasing frequency of marine-related activities such as marine resource development and marine scientific research has not only promoted the deep application of waterproof electrical connectors in underwater equipment (such as deep-sea detectors and underwater robots), but also driven the continuous growth in demand for underwater telephones. Underwater workers rely on waterproof electrical connectors to achieve power supply and signal interconnection for underwater equipment, and at the same time, they use underwater telephones for real-time communication and information transmission. The two work together to ensure the efficient progress of underwater operations and the safety of personnel.

[0003] In underwater environments, equipment is subject to external forces such as water flow and pressure fluctuations. Water continuously seeps into the connection points through gaps in the connecting parts. In underwater telephones, this can cause unclear voice signals and severe noise, making it difficult for both parties to communicate smoothly. At the same time, external forces can loosen the connection points of the waterproof electrical connector, resulting in poor contact. For underwater telephones, this can loosen the outer casing, interfering with normal operation. Under water pressure, the equipment structure may even be damaged, rendering it unable to continue operating. This necessitates frequent repairs and component replacements, increasing maintenance costs and workload. To address this, we propose a waterproof electrical connector for underwater communication equipment and an underwater telephone. Summary of the Invention

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 As shown, the present invention provides a technical solution: a waterproof electrical connector and an underwater telephone for underwater communication equipment, including a communication host component 1 for voice communication, an audio communication terminal 103 inside the communication host component 1, a built-in waterproof sealing component 2 inside the communication host component 1 for preventing external water from contacting the audio communication terminal 103, a multi-segment waterproof sealing component 3 for sealing the electrical connector on one side of the communication host component 1, and a sealing sleeve component 4 for enhancing the waterproof sealing of the multi-segment waterproof sealing component 3 outside the multi-segment waterproof sealing component 3;

[0029] Furthermore, during operation, the communication host component 1 transmits and processes voice signals through its internal audio communication terminal 103 to achieve voice communication. The built-in waterproof sealing component 2 always functions to keep external water out of the communication host component 1, keeping the audio communication terminal 103 in a dry environment and ensuring its normal operation. When connected to the communication host component 1 via an electrical connector, the electrical connector is sealed with a multi-segment waterproof sealing component 3 to prevent water from seeping in. At the same time, a sealing sleeve component 4 is fitted over the multi-segment waterproof sealing component 3 to reinforce and supplement the sealing from the outside, further enhancing the waterproof capability of the electrical connector. This allows the entire device to conduct voice communication stably and reliably in a wet environment.

[0030] In the preferred embodiment of this technical solution, please refer to Figure 2 As shown, the communication host component 1 includes a sealed enclosure 101, a sealed cover 102 is movably installed on the upper end of the sealed enclosure 101, and an audio communication terminal 103 is provided inside the upper end of the sealed enclosure 101. The sealed enclosure 101, the sealed cover 102, and the audio communication terminal 103 are all made of waterproof material. The built-in waterproof sealing component 2 includes a silicone waterproof gasket 201. The silicone waterproof gasket 201 is fixedly installed on one side of the four corners of the inner wall of the sealed cover 102. A sealing waterproof ring 202 is fixedly installed on one side of the silicone waterproof gasket 201. A sealing groove 203 is opened on one side of the four corners of the top surface of the sealed enclosure 101. The sealing groove 203 is compatible with the silicone waterproof gasket 201. A sealing groove 204 is opened on one side of the sealing groove 203. The sealing groove 204 is compatible with the sealing waterproof ring 202. A sealing retainer ring 205 is fixedly installed on one side of the sealing groove 204.

[0031] Furthermore, when the sealing cover 102 is closed, it covers the sealing box 101. At this time, the silicone waterproof gasket 201 on the inner wall of the sealing cover 102 is embedded in the sealing groove 203 on the top surface of the sealing box 101, forming the first waterproof sealing barrier, which can prevent most of the external water from seeping in from the joint between the sealing cover 102 and the sealing box 101. At the same time, the sealing waterproof ring 202 inside the silicone waterproof gasket 201 is embedded in the sealing groove 204, forming the second waterproof sealing barrier, which further intercepts water that may seep through the gaps in the first barrier. The sealing retaining ring 205 is embedded in the sealing cover 102, constructing the third waterproof sealing barrier, so that it can continue to play a sealing role efficiently. In this way, with the multi-layer sealing structure of the built-in waterproof sealing component 2, combined with the waterproof material of the sealing box 101, the sealing cover 102 and the audio communication terminal 103 itself, external water can be effectively prevented from entering the interior of the sealing box 101, protecting the audio communication terminal 103 and other components, and ensuring the normal operation of the voice communication function.

[0032] In the preferred embodiment of this technical solution, please refer to Figure 7As shown, the multi-segment waterproof sealing assembly 3 includes a connecting end 301, which is fixedly connected to the lower end of one side of the sealing housing 101. An O-ring 302 is fitted on the outer side of the connecting end 301. A threaded tooth 303 is formed on the outer wall of one end of the connecting end 301. A waterproof tail shell 304 is fixedly connected to one end of the connecting end 301 near the threaded tooth 303. A locking bolt 305 is fitted on the outside of the threaded tooth 303. The O-ring 302 is located at the locking position. On one side of the inner wall of bolt 305, and on the other side of the inner wall of locking bolt 305, O-ring 306 is fixedly installed. Locking bolt 307 is provided on one side of locking bolt 305. A waterproof screw ring 308 is threadedly connected to the inner wall of locking bolt 307 near the inner wall of locking bolt 305. A sealing ring 309 is fixedly installed at one end of the waterproof screw ring 308. A connecting end 3010 is sleeved on the outer wall of the waterproof screw ring 308 and the sealing ring 309.

[0033] Furthermore, the multi-segment waterproof sealing assembly 3 achieves a waterproof effect through the coordinated operation of a multi-layer sealing structure. First, the connecting end 301 is fixedly connected to the sealing housing 101. When the external O-ring 302 engages with the connecting end 301 and the locking bolt 305, it forms the first seal, preventing some external water from entering. Next, the locking bolt 305 is threadedly connected to the connecting end 301 through the thread 303. While achieving tightening, the O-ring 306 on its inner wall forms the second seal, further enhancing the sealing performance. Then, the locking bolt 307 engages with the locking bolt 305, tightening the waterproof screw rubber ring 308 on one hand and on the other hand... The multi-segment waterproof sealing assembly 3 is fixed inside the sealing sleeve assembly 4 by the tightening action of the locking bolt 307. The waterproof screw rubber ring 308 is fitted onto the waterproof screw, relying on its own elasticity to seal the gap between the screw and the surrounding components. The sealing rubber ring 309 enhances the sealing effect at the end of the waterproof screw rubber ring 308. Finally, the connecting end 3010 is fitted onto the outer wall of the waterproof screw rubber ring 308 and the sealing rubber ring 309, further integrating the various sealing components and constructing a multi-segment sealing protection system. This effectively prevents external water from entering the sealed housing 101 through the multi-segment waterproof sealing assembly 3, thereby ensuring the safety of internal components such as the audio communication terminal 103 and ensuring the normal operation of the voice communication function.

[0034] In the preferred embodiment of this technical solution, please refer to Figure 8As shown, the sealing sleeve assembly 4 includes a connecting collar 401. The connecting collar 401 is fitted onto the side of the waterproof screw rubber ring 308 away from the lower end of the sealing housing 101. A second threaded tooth 402 is provided on the inner wall of the connecting collar 401, which meshes with the waterproof screw rubber ring 308. An O-ring 403 is fixedly installed at one end of the connecting collar 401, and a fixing washer 4004 is fixedly connected to one end of the connecting collar 401. A movable gasket 404 is movably installed on one side of the inner wall of 04. A rubber retaining ring 405 is fixedly installed on one side of the movable gasket 404. A moisture-absorbing potting compound 406 is fixedly installed on one side of the rubber retaining ring 405. A rubber retaining ring 407 is fixedly installed on one side of the moisture-absorbing potting compound 406. A connecting sleeve 408 is fixedly connected to one end of the fixed gasket 4004 near the lower end of one side of the sealing box 101. An O-ring 409 is fixedly installed on one side of the inner wall of the connecting sleeve 408.

[0035] Furthermore, the sealing sleeve assembly 4 achieves waterproofing and moisture-proofing through a multi-layer sealing structure and moisture-absorbing function. First, the connecting collar 401 engages with the waterproof screw ring 308 via the inner screw teeth 402, completing the connection and fixation with the multi-segment waterproof sealing assembly 3. The threaded engagement structure can also prevent some water from seeping in along the thread gaps. When the waterproof screw ring 308 is fully locked inside the connecting collar 401, one end of it will abut against the movable washer 404 and generate a squeezing force, causing the movable washer 404 to move closer to the rubber retainer ring 405. Then, the movable washer 404, the rubber retainer ring 405, and the moisture-absorbing potting compound 406 interact, and the squeezing force compresses the rubber retainer ring 405, thereby squeezing the moisture-absorbing potting compound 406 and preventing moisture penetration. A large amount of moisture accumulates at the moisture-absorbing potting compound 406. At the same time, the rubber retaining ring 405 and the rubber retaining ring 407 form a sealing barrier using the elasticity of rubber to prevent external water from entering. The moisture-absorbing potting compound 406 absorbs the trace amount of water vapor that enters, preventing water vapor from accumulating inside and damaging the components. The O-ring 403 prevents water from entering the connection between the connecting sleeve 401 and the fixing gasket 4004. Finally, the O-ring 409 on the inner wall of the connecting sleeve 408 cooperates with the sealing box 101 and other components to form another seal, further preventing water from entering. Through the cooperation of various components, the sealing sleeve assembly 4 effectively isolates the external water and internal moisture from affecting the device and the multi-section waterproof sealing assembly 3, ensuring the normal operation of functions such as audio communication.
