Technical Field
[0001] This utility model belongs to the field of underwater power technology, specifically relating to an underwater power supply with a waterproof structural connector. Background Technology
[0002] With the widespread application of underwater equipment, underwater power supplies are increasingly used in marine engineering, underwater robots, diving lights, and underwater monitoring systems. In practical applications, underwater power supplies must possess excellent waterproof performance to ensure long-term stable operation and equipment safety.
[0003] However, existing underwater power supplies suffer from limitations in their waterproofing structure, with a single waterproof layer and insufficient sealing reliability. Traditional underwater power supplies typically only have a single-layer waterproof structure at the connection between the power supply box and the power cord, which is insufficient to effectively prevent water infiltration. When the underwater environment involves prolonged immersion, high humidity, or high pressure, the power cord interface is prone to water leakage or electrical shock, leading to power supply damage or equipment failure.
[0004] The sealing performance of the connector depends on simple materials or external sealant. In the existing technology, most underwater power connectors rely on simple rubber sleeves, sealing rings or colloid filling to achieve waterproofing. This method is prone to loosening or aging under long-term use or mechanical vibration, resulting in reduced sealing performance and failure to guarantee long-term reliability.
[0005] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

The power supply housing has a panel mounting groove inside, in which the drive power panel is installed. A connector mounting groove is provided at the end of the panel mounting groove. A plurality of first wire-passing openings are evenly distributed on one side of the connector mounting groove, and a plurality of second wire-passing openings are evenly distributed on the other side of the connector mounting groove. The plurality of first wire-passing openings and the plurality of second wire-passing openings are arranged in a one-to-one correspondence. A plurality of panel power lines are evenly connected to the end of the drive power panel. One end of each panel power line passes through the first wire-passing opening and the second wire-passing opening sequentially. A first waterproof connector and a second waterproof connector are respectively connected to the outer side of each panel power line. The first waterproof connector is disposed in the first wire-passing opening, and the second waterproof connector is disposed in the second wire-passing opening.
[0008] Furthermore, the first waterproof connector includes a first connector component and a first connector locking ring. The first connector component is sleeved on the outside of the power cord of the panel. The front end of the first connector component is provided with a first threaded connector. The diameter of the first threaded connector is smaller than the diameter of the first wire-passing opening. The first threaded connector extends through the first wire-passing opening into the panel mounting groove. The inner side of the first connector locking ring is provided with a first threaded sidewall adapted to the first threaded connector. The first connector locking ring is sleeved on the outside of the first threaded connector. At the same time, the first threaded sidewall and the first threaded connector are threadedly engaged and fixedly connected, thereby fixing the first waterproof connector in the first wire-passing opening.
[0009] Furthermore, the inner side of the first connector component is uniformly provided with a plurality of positioning protrusions, and the inner side of the plurality of positioning protrusions is provided with a waterproof film. The waterproof film is sealed between the plurality of positioning protrusions and the outer surface of the power cord of the panel to form a tight fit structure.
[0010] Furthermore, a first sealing ring is provided on the outer side of the first threaded connector, and the first sealing ring is sealed between the edge of the first threaded connector and the edge of the first wire opening.
[0011] Furthermore, the second waterproof connector includes a second connector component and a second connector locking ring. The second connector component is sleeved on the outside of the power cord of the panel. The front end of the second connector component is provided with a second threaded connector. The diameter of the second threaded connector is smaller than the diameter of the second wire-passing opening. The second threaded connector extends through the second wire-passing opening into the connector mounting groove. The inner side of the second connector locking ring is provided with a second threaded sidewall adapted to the second threaded connector. The second connector locking ring is sleeved on the outside of the second threaded connector. At the same time, the second threaded sidewall and the second threaded connector are threadedly engaged and fixedly connected, thereby fixing the second waterproof connector in the second wire-passing opening.
[0012] Furthermore, the inner side of the second connector component is sealed with adhesive between the inner side of the second connector component and the outer surface of the panel power cord, and the adhesive is uniformly filled in the gap between the inner wall of the second connector component and the outer surface of the panel power cord.
[0013] Furthermore, a second sealing ring is provided on the outer side of the second threaded connector, and the second sealing ring is sealed between the edge of the second threaded connector and the edge of the second wire opening.
[0014] Furthermore, the inner surface edge of the panel mounting groove is uniformly provided with a number of fixing through posts, and the surface edge of the drive power panel is uniformly provided with a number of fixing through holes. The number of fixing through holes corresponds one-to-one with the number of fixing through posts, and is connected and fixed by fasteners passing through the fixing through holes and fixing through posts.
[0015] Furthermore, the upper cover of the power supply box is equipped with a power supply cover plate.
[0016] Furthermore, the edge of the power supply cover is fixed to the edge of the power supply box by welding, thereby forming a closed structure between the power supply cover and the power supply box.
[0017] This utility model has the following advantages: The underwater power supply forms a double-layer waterproof structure by setting a first waterproof connector and a second waterproof connector. The first waterproof connector provides a primary seal for the channel of the panel power cable from the inside of the drive power panel to the inside of the connector mounting groove, while the second waterproof connector provides a secondary seal for the channel of the panel power cable from the outside of the connector mounting groove to the underwater environment, effectively preventing underwater infiltration. When the first and second connector locking rings are tightened, an axial clamping force is generated, forming a stable, tightly fitted seal between the interior of the first and second connector components and the outer surface of the panel power cable. The first connector component contains several positioning protrusions. The strip and waterproof film are further compressed and adhered to the power cord of the panel through slight radial deformation. The first and second threaded joints are equipped with a first and a second sealing ring, which form an annular seal after locking. The glue-filled sealing layer inside the second joint component further enhances the sealing and protection effect. The fixing through-post in the panel mounting groove cooperates with the fixing through hole of the drive power panel to fix it and prevent the panel from loosening. The power box and the power cover are welded and sealed to improve the overall strength and pressure resistance, thereby ensuring the long-term stable operation of the underwater power body underwater, achieving a highly reliable waterproof sealing effect, and improving the safety, stability and connection reliability of underwater use.

Detailed Implementation
[0024] like Figures 1 to 5 As shown, an underwater power supply with a waterproof connector includes a power supply body 1, which includes a power box 10 and a drive power panel 20. The power box 10 has a panel mounting groove 11 inside, and the drive power panel 20 is installed in the panel mounting groove 11. The end of the panel mounting groove 11 has a connector mounting groove 12. The connector mounting groove 12 has a plurality of first wire-passing openings 121 evenly distributed on one side facing the panel mounting groove 11, and a plurality of second wire-passing openings 122 evenly distributed on the other side away from the panel mounting groove 11. The plurality of first wire-passing openings 121 and the plurality of second wire-passing openings 122 are arranged in a one-to-one correspondence. A plurality of panel power cables 21 are evenly connected to the end of the drive power panel 20, and one end of each panel power cable 21 passes through... The first wiring opening 121 and the second wiring opening 122 extend outwards. To improve the sealing and reliability for underwater use, a first waterproof connector 30 and a second waterproof connector 40 are respectively connected to the outside of the panel power cord 21. The first waterproof connector 30 is disposed in the first wiring opening 121, and the second waterproof connector 40 is disposed in the second wiring opening 122. In use, the first waterproof connector 30 provides a primary seal for the channel of the panel power cord 21 from the inside of the drive power panel 20 to the inside of the connector mounting groove 12, preventing moisture from seeping into the power box 10 along the outer wall of the wire. The second waterproof connector 40 provides a secondary seal for the channel of the panel power cord 21 from the outside of the connector mounting groove 12 to the underwater environment, forming a double-layer waterproof structure, thereby effectively improving the waterproof performance of the entire device.
[0025] In practical implementation, the first waterproof connector 30 includes a first connector component 31 and a first connector locking ring 32. The first connector component 31 is sleeved on the outside of the panel power cord 21. The front end of the first connector component 31 is provided with a first threaded connector 311. The diameter of the first threaded connector 311 is smaller than the diameter of the first wire-passing opening 121. The first threaded connector 311 extends through the first wire-passing opening 121 into the panel mounting groove 11. The inner side of the first connector locking ring 32 is provided with a first threaded sidewall 321 adapted to the first threaded connector 311. The first connector locking ring 32 is sleeved on the panel power cord 21. The first threaded connector 311 is located on the outside of the first threaded connector 311. At the same time, the first threaded sidewall 321 is threadedly engaged with the first threaded connector 311 and fixedly connected, thereby fixing the first waterproof connector 30 in the first wire-passing opening 121. In use, when the panel power cord 21 passes through the first waterproof connector 30, the first connector locking ring 32 tightens the first connector component 31 along the axial direction, and the tightening force makes the interior of the first connector component 31 fit tightly with the outer surface of the panel power cord 21, thereby forming a stable waterproof sealing structure at the first wire-passing opening 121.
[0026] In practical implementation, the inner side of the first connector component 31 is uniformly provided with a plurality of positioning protrusions 312, and the inner side of the plurality of positioning protrusions 312 is provided with a waterproof film 313. The waterproof film 313 is sealed between the plurality of positioning protrusions 312 and the outer surface of the panel power cord 21 to form a tight fit structure. In use, when the first connector locking ring 32 is tightened, the first connector component 31 is subjected to axial clamping force, and the plurality of positioning protrusions 312 undergo slight deformation in the radial direction, thereby driving the waterproof film 313 to be further pressed and adhered to the outer surface of the panel power cord 21, thereby achieving effective sealing of the panel power cord 21, preventing moisture or dust from seeping in from the first wire opening 121, and improving the overall waterproof performance and connection stability.
[0027] In practical implementation, a first sealing ring 314 is provided on the outer side of the first threaded connector 311. The first sealing ring 314 is sealed between the edge of the first threaded connector 311 and the edge of the first wire-passing opening 121. In use, when the first connector locking ring 32 is tightened to fix the first threaded connector 311 in the first wire-passing opening 121, the first sealing ring 314 undergoes elastic deformation after being subjected to axial compression force, thereby forming an annular sealing structure at the contact position between the first threaded connector 311 and the first wire-passing opening 121, further preventing external moisture or dust from entering the interior of the panel mounting groove 11, and improving the protection level and sealing reliability of the entire first waterproof connector 30.
[0028] In practical implementation, the second waterproof connector 40 includes a second connector component 41 and a second connector locking ring 42. The second connector component 41 is sleeved on the outside of the panel power cord 21. The front end of the second connector component 41 is provided with a second threaded connector 411. The diameter of the second threaded connector 411 is smaller than the diameter of the second wire-passing opening 122. The second threaded connector 411 extends through the second wire-passing opening 122 into the connector mounting groove 12. The inner side of the second connector locking ring 42 is provided with a second threaded sidewall 421 adapted to the second threaded connector 411. The second connector locking ring 42 is sleeved on the outside of the second threaded connector 411. Meanwhile, the second threaded... The threaded sidewall 421 is threadedly engaged with the second threaded connector 411 to fix the second waterproof connector 40 in the second wiring opening 122. In use, when the panel power cord 21 passes through the second waterproof connector 40, the second connector locking ring 42 tightens the second connector component 41 axially to generate a clamping force. This clamping force makes the interior of the second connector component 41 fit tightly against the outer surface of the panel power cord 21, thereby forming a stable waterproof sealing structure at the second wiring opening 122. This ensures that the electrical connection part inside the connector mounting groove 12 can maintain reliable protection performance in humid or dusty environments.
[0029] In practice, the inner side of the second connector component 41 and the outer surface of the panel power cord 21 are sealed with adhesive. The adhesive is evenly filled in the gap between the inner wall of the second connector component 41 and the outer surface of the panel power cord 21. After installation, the adhesive cures to form a flexible sealing layer, thereby effectively preventing external moisture or dust from seeping into the connector along the gap, further enhancing the sealing performance and protection level of the second waterproof connector 40, and ensuring that the panel power cord 21 is stable and waterproof during long-term use.
[0030] In practical implementation, a second sealing ring 412 is provided on the outer side of the second threaded connector 411. The second sealing ring 412 is sealed between the edge of the second threaded connector 411 and the edge of the second wire-passing opening 122. During use, when the second connector locking ring 42 is tightened to fix the second threaded connector 411 in the second wire-passing opening 122, the second sealing ring 412 is subjected to axial compression and generates elastic deformation, thereby forming a tight annular sealing structure at the contact point between the second threaded connector 411 and the second wire-passing opening 122. This effectively prevents external liquids or moisture from seeping into the connector mounting groove 12 from the second wire-passing opening 122, further improving the waterproof sealing effect of the second waterproof connector 40 and the overall safety and reliability of its use.
[0031] In practical implementation, the inner surface edge of the panel mounting groove 11 is uniformly provided with a plurality of fixing through posts 111, and the surface edge of the drive power panel 20 is uniformly provided with a plurality of fixing through holes 22. Each fixing through hole 22 corresponds to one fixing through post 111, and fasteners are used to connect and fix the drive power panel 20 to the fixing through posts 111 through the fixing through holes 22, thereby ensuring the drive power panel 20 is securely installed inside the panel mounting groove 11. During use, the mating connection between the fixing through posts 111 and the fixing through holes 22 effectively prevents the drive power panel 20 from shifting or loosening during transportation or operation.
[0032] In practical implementation, the upper end of the power supply box 10 is fitted with a power cover plate 50. The edge of the power cover plate 50 is welded to the edge of the power supply box 10, thereby forming a closed structure between the power cover plate 50 and the power supply box 10. During use, the welding fixing method effectively avoids the gap problems that may occur with bolted or snap-fit connections, further improving the overall waterproof sealing performance. At the same time, this welded connection structure enhances the overall strength and pressure resistance of the power supply box 10, preventing the cover plate from loosening or leaking due to high-pressure underwater environments or external impacts, thus ensuring the long-term stable operation of the underwater power supply.
[0033] In summary, this underwater power supply forms a double-layer waterproof structure by setting a first waterproof connector 30 and a second waterproof connector 40. The first waterproof connector 30 provides a primary seal for the channel of the panel power cable 21 from the inside of the drive power panel 20 to the inside of the connector mounting groove 12, while the second waterproof connector 40 provides a secondary seal for the channel of the panel power cable 21 from the outside of the connector mounting groove 12 to the underwater environment, effectively preventing underwater infiltration. When the first connector locking ring 32 and the second connector locking ring 42 are tightened, an axial clamping force is generated, forming a stable and tightly fitted seal between the inside of the first connector component 31 and the second connector component 41 and the outer surface of the panel power cable 21. The first connector component 31 is provided with several positioning protrusions 312 and waterproof adhesive. The plate 313 further presses and adheres to the power cord 21 of the panel through slight radial deformation. The first threaded connector 311 and the second threaded connector 411 are provided with a first sealing ring 314 and a second sealing ring 412, which form an annular seal after locking. The glue filling sealing layer in the second connector component 41 further enhances the sealing and protection effect. The fixing through post 111 in the panel mounting groove 11 cooperates with the fixing through hole 22 of the drive power panel 20 to fix it and prevent the panel from loosening. The power box 10 and the power cover plate 50 are welded and sealed to improve the overall strength and pressure resistance, thereby ensuring the long-term stable operation of the underwater power body 1 underwater, achieving a highly reliable waterproof sealing effect, and improving the safety, stability and connection reliability of underwater use.
