Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and more specifically, to a high-speed electrical connector with good sealing performance. Background Technology

[0002] Electrical connectors are primarily used for circuit connections between cables and between cables and equipment in electrical and electronic devices, enabling the transmission of low-frequency signals, high-frequency signals, and electrical energy (power). An electrical connector consists of two parts: a socket and a plug. The socket is the passive connection part, and the plug is the active connection part, mating with the socket. The electrical connector connects and disconnects the circuit by the mating and disconnection of the plug and socket. Electrical connectors play a crucial bridging role in the transmission of electrical signals in circuits, and circular electrical connectors are among the most widely used types.

[0003] Chinese invention patent publication number CN112886315A discloses a miniaturized anti-loosening circular electrical connector, comprising a plug and a socket that mat with each other. The plug includes a plug housing and a threaded sleeve, with the threaded sleeve fitted onto the outside of the plug housing. A collar is provided on the outer ring of the plug housing. A shoulder is provided on one side of the collar in the inner hole of the threaded sleeve, and a retaining ring is installed in the inner hole of the threaded sleeve via a retaining strip on the other side of the collar, restricting the collar between the shoulder and the retaining ring. Compared with the existing retaining ring structure, the radial dimension space requirement of the limiting groove is reduced by one-third, resulting in higher space utilization and allowing for a smaller overall size and lighter connector weight, meeting the development requirements of lightweight and miniaturization.

[0004] However, the above-mentioned device still has shortcomings. Although the device connects the plug and socket of the electrical connector together, there will be a certain gap at the connection point due to the manufacturing process and long-term use.

Ultimately, the air bladder adheres to the outer wall of the base and exerts a certain compressive force. At this point, the air bladder seals the gap between the insertion cylinder and the base, greatly preventing liquids and dust from entering through the space between the outer sleeve and the insertion cylinder. This complete seal effectively prevents liquids or dust from entering the internal connection points of the electrical connector, preventing malfunctions such as connector failure or short circuits. This significantly improves the connection effect of the electrical connector, resulting in good sealing and high safety. Attached Figure Description

[0030] Example 1:

[0031] Please see Figure 1-3 , Figure 6 and Figure 10-11A high-speed electrical connector with good sealing performance includes an electrical connector plug 1 and an electrical connector socket 2. The electrical connector plug 1 and the electrical connector socket 2 are respectively provided with an insertion cylinder 3 and an outer sleeve 4. The side wall of the insertion cylinder 3 has multiple transmission cavities 5 and mating cavities 6. An airbag ring 7 is fixedly installed on the inner wall of the insertion cylinder 3. The inner wall of the insertion cylinder 3 has multiple openings that connect the airbag ring 7 and the mating cavities 6. The transmission cavity 5 is provided with a transmission mechanism 8 that drives the airbag ring 7 to expand. The electrical connector socket 2 is provided with a movable mounting ring 9. Multiple trigger rods 10 are fixedly connected to one end of the mounting ring 9 near the outer sleeve 4. The trigger rods 10 move through the outer wall of the outer sleeve 4 and extend into its interior. The electrical connector socket 2 is provided with a base 27 located inside the outer sleeve 4. Multiple electrical connection holes 36 are opened inside the base 27. Multiple electrical connection pins 37 that are inserted into the electrical connection holes 36 are fixedly installed inside the electrical connector plug 1. The electrical connection pins 37 are located inside the insertion cylinder 3. When using this device, first align the insertion tube 3 of the electrical connector plug 1 to be connected with and insert it into the outer sleeve 4 of the electrical connector socket 2. The insertion tube 3 will then enter the outer sleeve 4. Figure 1 and Figure 10 As shown, the mounting ring 9 and trigger rod 10 are then moved. The trigger rod 10 moves towards the insertion cylinder 3. Finally, through the cooperation of the trigger rod 10 and the transmission mechanism 8, the gas in the mating cavity 6 is compressed, causing the gas to flow into the airbag ring 7, thereby causing the airbag ring 7 to expand. Ultimately, the airbag ring 7 will adhere to the outer wall of the base 27 and be subject to a certain compressive force, such as... Figure 10-11 As shown, the gap between the insertion cylinder 3 and the base 27 can be sealed by the airbag ring 7, which can greatly prevent liquid and dust from entering between the outer sleeve 4 and the insertion cylinder 3 from entering through the space between the insertion cylinder 3 and the base 27. The seal is complete, which greatly prevents liquid or dust from entering the internal connection of the electrical connector, preventing failure of the electrical connector or short circuit, and greatly improving the connection effect of the electrical connector, with high safety.

[0032] In this embodiment, preferably, please refer to [reference needed]. Figure 4The transmission mechanism 8 includes a first spring 801 fixedly connected to the inner wall of the transmission cavity 5. A first mating block 802 is fixedly provided at the movable end of the first spring 801. A transmission rod 803 is fixedly connected to the outer wall of the first mating block 802. The transmission rod 803 movably passes through the inner wall of the transmission cavity 5. A piston plate 804 is fixedly provided at the end of the transmission rod 803 away from the first mating block 802 and slidably connected to the inner wall of the mating cavity 6. A drive assembly is provided in the transmission cavity 5 to drive the piston plate 804 to descend. The drive assembly includes a hollow column 11 fixedly connected to the inner wall of the transmission cavity 5. A movable column 12 is slidably connected to the inner wall of the hollow column 11. A shaped block 13 is fixedly installed at the end of the movable column 12. One side of the shaped block 13 is slidably attached to the first mating block 802. A second spring 14 is fixedly connected between the shaped block 13 and the inner wall of the transmission cavity 5. An insertion port 15 communicating with the hollow column 11 is opened on the outer wall of the insertion cylinder 3. When the insertion cylinder 3 moves, it enters the hollow column 11 through the insertion port 15, then presses against the movable column 12 and drives it and the irregular block 13 to move, and stretches the second spring 14. When the irregular block 13 moves, it drives the first mating block 802 and the transmission rod 803 to move away from the transmission cavity 5, and compresses the first spring 801. The transmission rod 803 drives the piston plate 804 to move, and the piston plate 804 will compress the gas in the mating cavity 6.

[0033] In this embodiment, preferably, please refer to [reference needed]. Figure 6 and Figure 9 The outer wall of the electrical connector 2 is threaded and screwed with a connecting ring 33. The side wall of the connecting ring 33 has a groove 34, and a slider 35 is slidably connected to the inner wall of the groove 34. The end of the slider 35 away from the connecting ring 33 is fixedly connected to the outer wall of the mounting ring 9. When the connecting ring 33 is rotated, it moves on the electrical connector 2 toward the outer sleeve 4. When the connecting ring 33 rotates, it also drives the slider 35 to rotate along the groove 34. In turn, the movement of the connecting ring 33 also drives the mounting ring 9 and the trigger rod 10 to move.

[0034] Example 2:

[0035] Based on Example 1, please refer to Figure 2-5 and Figure 11A third spring 16 is fixedly connected to the inner wall of the transmission cavity 5. A second mating block 17 is fixedly connected to the movable end of the third spring 16. The second mating block 17 slides and fits against the other inclined side of the irregular block 13. A moving rod 18 is fixedly connected to the outer wall of the second mating block 17. The outer end of the moving rod 18 moves through the outer wall of the insertion cylinder 3 and is fixedly installed with a limiting plate 19. A blocking ring plate 20 is fixedly installed on the inner wall of the outer sleeve 4. When the irregular block 13 moves, it will also drive the second mating block 17 and the moving rod 18 to move, and at the same time compress the third spring 16. When the moving rod 18 moves, it will drive the limiting plate 19 to move. At this time, the limiting plate 19 will move away from the outer wall of the insertion cylinder 3 and move towards the inner wall of the outer sleeve 4. Finally, the limiting plate 19 will move to the side of the blocking ring plate 20. Figure 10-11 As shown, the insertion cylinder 3 can be restricted by the limiting plate 19 and the blocking ring plate 20, preventing it from accidentally detaching from the outer sleeve 4 during connection and use. This avoids the electrical connection socket 36 from detaching from the electrical connection pin 37, which could lead to accidental disconnection of the electrical connector. This prevents accidental pulling between the electrical connector plug 1 and the electrical connector socket 2, thus improving the stability of the connection and enhancing the performance of the electrical connector. It also prevents the insertion cylinder 3 from moving out of the outer sleeve 4 during use, which could further reduce the sealing performance. Furthermore, it avoids the cumbersome use of bolts for fixing and greatly reduces the risk of bolt corrosion or loosening that could affect the sealing performance, significantly improving practicality.

[0036] Example 3:

[0037] Based on Example 1, please refer to Figure 5-8The inner wall of the outer sleeve 4 is provided with interconnected drainage chambers 21 and multiple sets of drainage holes 22. The outer wall of the outer sleeve 4 is provided with multiple water outlets 23 that communicate with the drainage chambers 21. A one-way valve is installed inside the water outlets 23. A partition 24 is fixedly provided on the inner wall of the drainage chamber 21. A force-bearing plate 25 is slidably connected to the partition 24 and the inner wall of the drainage chamber 21. The force-bearing plate 25 and the inner wall of the drainage chamber 21 form an air storage chamber. A fourth spring 26 is fixedly provided between the force-bearing plate 25 and the inner wall of the air storage chamber. A triggering component that cooperates with the air storage chamber is provided in the base 27. The triggering component includes a triggering groove 28 opened inside the base 27. A connecting channel 29 connecting the air storage chamber and the triggering groove 28 is opened in the outer sleeve 4. A pre-breaking layer 30 is fixedly installed at the opening of the triggering groove 28. An elastic membrane 31 is fixedly connected to the inner wall of the triggering groove 28. Polyurethane sealant is filled between the elastic membrane 31 and the pre-breaking layer 30. A spike 32 is fixedly provided on the inner wall of the elastic membrane 31 near the pre-breaking layer 30. During use, if water enters the area between the outer sleeve 4 and the insertion sleeve 3, the water will flow from the drain hole 22 on the inner wall of the outer sleeve 4 into the drain chamber 21, and finally flow out to the outside through the outlet 23, thus preventing water from accumulating inside the outer sleeve 4 and affecting the use of the electrical connector. When the electrical connector plug 1 and electrical connector socket 2 are immersed in water or flooded by heavy rain, water entering the electrical connector may seriously threaten circuit failure and may also cause problems with other circuits it is paired with. At this time, the amount of water entering the drainage chamber 21 increases. When the amount of water in the drainage chamber 21 exceeds the amount of water flowing out of the outlet 23, the water in the drainage chamber 21 will cause the force plate 25 to move along the partition 24 and compress the fourth spring 26. The force plate 25 will squeeze the gas in the gas storage chamber into the connecting channel 29. The gas in the connecting channel 29 will then enter the trigger groove 28, which will compress the elastic membrane 31, causing the elastic membrane 31 to deform. When the deformation reaches a certain degree, the spike 32 will contact the pre-breaking layer 30. The pre-puncture layer 30 is punctured, at which point the polyurethane sealant in the elastic membrane 31 overflows and fills the gap between the insertion cylinder 3 and the base 27. This fills the gap and will be fixed and bonded after a period of time, which can further effectively prevent water from passing through the position between the insertion cylinder 3 and the base 27 and entering the insertion connection between the electrical connection pin 37 and the base 27. This can greatly avoid serious circuit failure caused by water ingress and further ensure the safety of the circuit and its use.

[0038] Working principle: When using this device, first align the insertion tube 3 of the electrical connector plug 1 to be connected with and insert it into the outer sleeve 4 of the electrical connector socket 2. The insertion tube 3 enters the outer sleeve 4, at which point the electrical connection pin 37 inside the insertion tube 3 will insert into the electrical connection socket 36 of the base 27. Simultaneously, the base 27 inside the outer sleeve 4 will enter the insertion tube 3. Once the designated position is reached, the connection is established. Figure 1 and Figure 10 As shown, the connecting ring 33 is then rotated, and the connecting ring 33 moves towards the outer sleeve 4 on the electrical connection socket 2. When the connecting ring 33 rotates, it also drives the slider 35 to rotate along the slide groove 34. In turn, the movement of the connecting ring 33 also drives the mounting ring 9 and the trigger rod 10 to move. At this time, the trigger rod 10 moves towards the insertion cylinder 3. Finally, the insertion cylinder 3 enters the hollow column 11 through the insertion port 15, then abuts against the movable column 12 and drives it and the irregular block 13 to move, stretching the second spring 14. When the irregular block 13 moves, it drives the first mating block 802 and the transmission rod 803 to move away from the transmission cavity 5, and compresses the first spring 801. The transmission rod 803 drives the piston plate 804 to move. The piston plate 804 compresses the gas in the mating cavity 6, causing the gas to flow towards the inside of the airbag ring 7, thereby causing the airbag ring 7 to expand. Finally, the airbag ring 7 will be in contact with the outer wall of the base 27 and have a certain compressive force. Figure 10-11 As shown, the gap between the insertion cylinder 3 and the base 27 can be sealed by the airbag ring 7. This seals the entrance to the insertion connection between the power-connected pin 37 and the base 27, thus greatly preventing liquid and dust from entering between the outer sleeve 4 and the insertion cylinder 3 from entering through the space between the insertion cylinder 3 and the base 27. The seal is complete and the safety is high.

[0039] When the irregular block 13 moves, it also drives the second mating block 17 and the moving rod 18 to move, and simultaneously compresses the third spring 16. When the moving rod 18 moves, it drives the limiting plate 19 to move. At this time, the limiting plate 19 will move away from the outer wall of the insertion cylinder 3 and move towards the inner wall of the outer sleeve 4. Finally, the limiting plate 19 will move to the side of the blocking ring plate 20, as shown. Figure 10-11 As shown, the insertion cylinder 3 can be restricted by the limiting plate 19 and the blocking ring plate 20 to prevent the insertion cylinder 3 from accidentally detaching from the outer sleeve 4 during connection and use.

[0040] When it is necessary to separate the electrical connector plug 1 and the electrical connector socket 2, the connecting ring 33 can be rotated to move it away from the outer sleeve 4. The connecting ring 33 will then drive the mounting ring 9 and the trigger rod 10 to move. At this time, the trigger rod 10 will gradually move away from the movable column 12 and the socket 15. At this time, the second spring 14 will drive the irregular block 13 to gradually return to its initial position. At this time, the transmission rod 803 and the first mating block 802 will return to their initial positions through the first spring 801. That is, the transmission rod 803 will drive the piston plate 804 to move away from the airbag ring 7 and return to its initial state. At this time, the airbag ring 7 will no longer expand and adhere to the outer wall of the base 27. At the same time, the second mating block 17 and the moving rod 18 will also return to their initial positions through the action of the third spring 16. That is, the moving rod 18 will drive the limiting plate 19 to move closer to the outer wall of the insertion cylinder 3 and finally return to its initial form. It will no longer be restricted by the blocking ring plate 20. At this time, the insertion cylinder 3 can be removed from the outer sleeve 4, and the disassembly can be completed. It is simple and convenient.

[0041] During use, if water enters the area between the outer sleeve 4 and the insertion sleeve 3, the water will flow from the drain hole 22 on the inner wall of the outer sleeve 4 into the drain chamber 21, and will eventually flow out to the outside through the outlet 23, thus preventing it from affecting the use of the electrical connector. When the electrical connector plug 1 and electrical connector socket 2 are immersed in water or flooded by heavy rain, water entering the electrical connector may seriously threaten circuit failure and may also cause problems with other circuits it is paired with. At this time, the amount of water entering the drainage chamber 21 increases. When the amount of water in the drainage chamber 21 is greater than the amount of water coming out of the outlet 23, the water in the drainage chamber 21 will drive the force plate 25 to move along the partition 24 and compress the fourth spring 26. The force plate 25 will squeeze the gas in the gas storage chamber into the connecting channel 29. The gas in the connecting channel 29 will then enter the trigger groove 28, which will squeeze the elastic membrane 31 and cause it to deform. When the deformation reaches a certain degree, the spike 32 will contact the pre-breaking layer 30 and puncture it. At this time, the polyurethane sealant in the elastic membrane 31 will overflow and fill the gap between the insertion cylinder 3 and the base 27. This will fill the gap and further effectively prevent water from entering, ensuring the safety of the circuit and its use.
