Description

Technical Field

[0001] This application relates to the field of underwater radio frequency connection technology, and in particular to a pressure-resistant water-sealed radio frequency connector. Background Technology

[0002] Radio frequency (RF) connectors are essential data connection devices. However, conventional RF connectors cannot be used directly underwater. To avoid this, a sealed rigid box is used to fix the RF connector's socket and plug at both ends of the rigid box, achieving the connection within the box. This prevents water intrusion. However, in actual use, the device is often underwater, resulting in a humid working environment for the connector, which is prone to electrolytic corrosion. Furthermore, the rigid sealed container deforms under immense pressure in deep water, and this deformation is transmitted to the RF connector through the connector components, causing the connectors to squeeze against each other and resulting in structural damage. Therefore, this application proposes a pressure-resistant, water-sealed RF connector to address these problems. Summary of the Invention

[0003] This application proposes a pressure-resistant water-sealed radio frequency connector, which has the advantage of automatically adjusting the position of the RF connector plug and socket according to the water depth, in order to solve the deformation and extrusion problem caused by rigid connection.

[0004] To achieve the above objectives, this application adopts the following technical solution: a pressure-resistant water-sealed radio frequency connector, including a housing, with travel sleeves provided on both sides of the housing, and a water-sealed travel plate movably installed inside the travel sleeve, the water-sealed travel plate moving inward along the axial direction of the travel sleeve under the action of water pressure.

[0005] Specifically, a connecting plug is fixedly installed at the center of the water-sealed travel plate, and a balance spring is provided on the front of the water-sealed travel plate outside the connecting plug. Adjusting sleeves are provided at the top and bottom of the housing. The top of the adjusting sleeve has a threaded hole, and an adjusting device is installed on the top of the adjusting sleeve through the threaded hole. The adjusting device is connected to the balance spring. Guide devices are fixedly installed on both sides of the inner wall of the housing, and a travel device is movably installed on the front of the guide device.

[0006] Furthermore, the portion of the outer surface of the water-sealed travel plate that contacts the inner wall of the travel sleeve is sealed, and a waterproof cover is provided on the top of the adjustment device.

[0007] Furthermore, the adjusting device includes a threaded sleeve, the outer surface of which is provided with threads and engages with the threaded hole at the top of the adjusting sleeve. When the threaded sleeve is rotated, it moves along the axial direction under the action of the thread.

[0008] Specifically, a first push rod is movably fitted on both sides of the outer surface of the threaded sleeve near the bottom. One end of the first push rod is movably fitted with an annular sliding plate, which is movably positioned inside the travel sleeve. When the threaded sleeve moves downward, the first push rod pushes the two annular sliding plates away from each other. When the threaded sleeve moves upward, the first push rod pushes the two annular sliding plates closer to each other.

[0009] Specifically, a telescopic rod is movably installed inside the threaded sleeve, the telescopic rod passes through the bottom of the threaded sleeve and extends to the bottom of the threaded sleeve, and a second push rod is movably sleeved on both sides of the outer surface of the telescopic rod near the bottom, one end of the second push rod being connected to the stroke device;

[0010] Specifically, one end of the balance spring is connected to the annular sliding plate.

[0011] Furthermore, the telescopic rod has flow guide holes at both the top and bottom, and the flow guide holes at the top and bottom are connected by pipes. A pressure guide pipe is provided at the bottom of the telescopic rod corresponding to the flow guide hole, and one end of the pressure guide pipe is connected to the guide device.

[0012] Furthermore, the guiding device includes a mounting bracket, a sliding rod on the front of the mounting bracket, and guide rails on the front of the mounting bracket above and below the sliding rod. A travel device is movably mounted on the front of the mounting bracket via the sliding rod and guide rails. Two strip-shaped holes are formed on the front of the mounting bracket between the guide rails, and the number of these holes is symmetrically distributed. A pressure-guiding chamber is provided on the back of the mounting bracket, and a locking device is movably mounted inside the pressure-guiding chamber. A connection port is provided on the back of the pressure-guiding chamber, communicating with the inner cavity of the pressure-guiding chamber and connecting to one end of a pressure-guiding tube. A return spring is provided on the outer side of the sliding rod, and both ends of the return spring are connected to the two travel devices respectively.

[0013] Furthermore, the locking device includes a pressure plate, a locking block is fixedly installed on the front of the pressure plate near the center, a ratchet is provided on the front of the locking block, and pressure springs are provided on the front of the pressure plate on both sides of the locking block, with the front end of the pressure springs connected to the inner wall of the pressure guiding chamber.

[0014] Furthermore, the cross-sectional shape of the locking block is the same as the opening shape of the strip hole.

[0015] Furthermore, the travel device includes a displacement plate, a connecting socket is provided at the center of the displacement plate, and sliding holes are provided on the front of the displacement plate on both sides of the connecting socket. The sliding holes are slidably engaged with the sliding rod. Travel seats are fixedly installed at both ends of the displacement plate and are slidably engaged with the guide rail. A contact groove is provided on the front of the travel seat at the middle position. The contact groove is provided with ratchet teeth, which correspond to the ratchet teeth provided on the front of the locking block. A coupling seat is provided at the top and bottom near the end of the outer surface of the connecting socket, and the coupling seat is connected to the second push rod.

[0016] Furthermore, the axis of the connector plug and the axis of the connector socket are located on the same center line.

[0017] Specifically, the surface of the connection between the connector and the socket is provided with an anti-corrosion coating, which adopts an anti-corrosion coating structure of electroplated rhodium, ruthenium, platinum and palladium nickel.

[0018] Furthermore, under pressure, the locking block extends out from the inside of the slot, and the ratchet on the front of the locking block contacts the ratchet inside the contact groove. At this time, the two travel devices can only move in directions away from each other.

[0019] This application has the following beneficial effects.

[0020] 1. The connection surface is coated with an anti-corrosion coating. The anti-corrosion coating adopts a combination of electroplated rhodium, ruthenium, platinum and palladium nickel. This can avoid the problem of electrolytic corrosion of the connector plug and socket due to being underwater and in a humid environment, which can damage the connector plug and socket structure and affect the quality of data transmission, thus improving the reliability of the device.

[0021] 2. By adopting a variable volume design method, the deeper the device is located, the smaller the area of ​​the outer shell surface that participates in resisting pressure after the water seal travel plate and telescopic rod move, thus reducing the probability of deformation of the outer shell. At the same time, the total volume of the inner cavity of the outer shell becomes smaller, and the gas inside is compressed, resulting in an increase in gas pressure. This reduces the pressure difference between the inside and outside of the outer shell, minimizing the risk of deformation of the outer shell under the action of the pressure difference.

[0022] 3. The separate design avoids the water pressure on the water seal plate from directly affecting the connection between the connector and the socket. As the water pressure increases, the excessive interaction force between the connector and the socket can easily cause damage.

[0023] 4. The distance between the annular slide plate and the connector plug can be adjusted by rotating the threaded sleeve pipe, so that the pressure intensity borne by the water seal travel plate when the connector plug and connector socket are in the connected state is adapted to the travel distance of the connector plug, thereby realizing that the device can be appropriately adjusted according to the depth of the location.

[0024] 5. When underwater, the locking device extends from the inside of the slot and locks with the contact groove to prevent the travel device from resetting and causing unstable connection. In addition, when the device is retrieved from the water for maintenance, it automatically releases the lock, allowing the travel device to reset under the elastic force of the return spring, thus ensuring that the connector socket and connector plug can be separated for easy maintenance.

[0025] 6. When the device is used in a non-underwater environment, a rod can be inserted into the top of the threaded sleeve, and the threaded sleeve can be rotated to move the annular slide plate closer to each other. At the same time, the water seal travel plate and the connector can be moved closer to each other, and the connector and the connector can be connected normally in non-underwater conditions.

[0040] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0041] A pressure-resistant water-sealed RF connector, please refer to Figures 1-4 It includes an outer shell 1, and a travel sleeve 2 is provided on both sides of the outer shell 1. A water-sealed travel plate 3 is movably installed inside the travel sleeve 2. Under the action of water pressure, the water-sealed travel plate 3 moves inward along the axial direction of the travel sleeve 2.

[0042] Please see Figures 1-4 A connecting plug 4 is fixedly installed at the center of the water-sealed travel plate 3. A balance spring 5 is provided on the front of the water-sealed travel plate 3 outside the connecting plug 4. An adjusting sleeve 6 is provided at the top and bottom of the housing 1. A threaded hole is opened at the top of the adjusting sleeve 6. An adjusting device 7 is installed on the top of the adjusting sleeve 6 through the threaded hole. The adjusting device 7 is connected to the balance spring 5. Guide devices 8 are fixedly installed on both sides of the inner wall of the housing 1. A travel device 9 is movably installed on the front of the guide device 8.

[0043] Please see Figures 1-4The portion of the outer surface of the water-sealed travel plate 3 that contacts the inner wall of the travel sleeve 2 is sealed, and a waterproof cover is provided on the top of the adjusting device 7.

[0044] By adopting a variable volume design method, the deeper the device is located, the smaller the area of ​​the outer shell 1 that participates in resisting pressure after the water seal travel plate 3 and the telescopic rod 74 move, thus reducing the probability of deformation of the outer shell 1. At the same time, the total volume of the inner cavity of the outer shell 1 becomes smaller, and the gas inside is compressed, resulting in an increase in gas pressure. This reduces the pressure difference between the inside and outside of the outer shell 1, minimizing the risk of deformation of the outer shell 1 under the action of the pressure difference between the inside and outside.

[0045] Please see Figures 5-6 The adjusting device 7 includes a threaded sleeve 71. The outer surface of the threaded sleeve 71 is provided with threads and it cooperates with the threaded hole at the top of the adjusting sleeve 6. When the threaded sleeve 71 is rotated, the threaded sleeve 71 moves along the axial direction under the action of the thread.

[0046] Please see Figure 1 and Figures 5-6 The threaded sleeve 71 has a first push rod 72 movably fitted on both sides of its outer surface near the bottom. One end of the first push rod 72 is movably fitted with an annular slide plate 73, which is movably disposed inside the stroke sleeve 2. When the threaded sleeve 71 is moving downward, the first push rod 72 pushes the two annular slide plates 73 away from each other. When the threaded sleeve 71 is moving upward, the first push rod 72 pushes the two annular slide plates 73 closer to each other.

[0047] Please see Figure 3 and Figures 5-6 The threaded sleeve 71 is movably installed with a telescopic rod 74 inside. The telescopic rod 74 passes through the bottom of the threaded sleeve 71 and extends to the bottom of the threaded sleeve 71. A second push rod 75 is movably sleeved on both sides of the outer surface of the telescopic rod 74 near the bottom. One end of the second push rod 75 is connected to the stroke device 9.

[0048] Please see Figure 3 and Figure 5 One end of the balance spring 5 is connected to the annular slide plate 73.

[0049] Please see Figure 3 and Figures 5-6 The telescopic rod 74 has flow guide holes 76 at both the top and bottom, and the flow guide holes 76 at the top and bottom are connected by pipes. A pressure guide pipe 77 is provided at the bottom of the telescopic rod 74 at the position corresponding to the flow guide hole 76, and one end of the pressure guide pipe 77 is connected to the guide device 8.

[0050] When the device is at a shallow depth, the threaded sleeve 71 can be rotated before use, causing it to move upwards. Simultaneously, the annular slide plate 73 moves closer to each other, increasing the distance between it and the connector 4. Under the traction of the balance spring 5, the water seal travel plate 3 and the connector 4 move closer to the connector socket 92, reducing the pressure on the water seal travel plate 3 when the connector 4 and connector socket 92 are connected. This allows the device to operate normally even at shallow depths. Similarly, rotating the threaded sleeve 71 in the opposite direction increases the pressure on the water seal travel plate 3 when the connector 4 and connector socket 92 are connected. This allows the device to be adjusted appropriately according to the depth of the location, enabling it to adapt to working conditions at various depths and improving its practicality.

[0051] When the device is underwater, the water pressure acts on the top of the telescopic rod 74 and causes the telescopic rod 74 to move downward. During this process, the second push rods 75 on both sides push the two stroke devices 9 to move away from each other, thereby shortening the distance between the connector plug 4 and the connector socket 92. This ensures that after the connector plug 4 is displaced under the action of water pressure, the connector plug 4 and the connector socket 92 can be stably connected, avoiding the problem of frequent loosening of the connection between the connector plug 4 and the connector socket 92 due to unstable pressure.

[0052] Please see Figures 7-9 The guiding device 8 includes a mounting bracket 81. A sliding rod 82 is provided on the front of the mounting bracket 81. Guide rails 83 are provided on the front of the mounting bracket 81 above and below the sliding rod 82. A stroke device 9 is movably mounted on the front of the mounting bracket 81 via the sliding rod 82 and the guide rails 83. Two strip holes 84 are provided on the front of the mounting bracket 81 between the guide rails 83 and are distributed symmetrically on an axis. A pressure guiding chamber 85 is provided on the back of the mounting bracket 81. A locking device 86 is movably mounted inside the pressure guiding chamber 85. A connection port 87 is provided on the back of the pressure guiding chamber 85 and communicates with the inner cavity of the pressure guiding chamber 85. The connection port 87 is connected to one end of the pressure guiding tube 77. A return spring 88 is provided on the outside of the sliding rod 82. The two ends of the return spring 88 are respectively connected to the two stroke devices 9.

[0053] Please see Figures 9-10The locking device 86 includes a pressure plate 861. A locking block 862 is fixedly installed on the front of the pressure plate 861 near the center. The front of the locking block 862 is provided with ratchet teeth. Pressure springs 863 are provided on the front of the pressure plate 861 on both sides of the locking block 862. The front end of the pressure springs 863 is connected to the inner wall of the pressure guiding chamber 85.

[0054] Please see Figure 8 and Figure 10 The cross-sectional shape of the locking block 862 is the same as the opening shape of the strip hole 84.

[0055] Please see Figure 6 , Figure 8 and Figures 10-11 The travel device 9 includes a displacement plate 91, a connecting socket 92 at the center of the displacement plate 91, and sliding holes 93 on both sides of the connecting socket 92 on the front of the displacement plate 91. The sliding holes 93 are slidably engaged with the slide rod 82. Travel seats 94 are fixedly installed at both ends of the displacement plate 91 and are slidably engaged with the guide rail 83. A contact groove 95 is provided in the middle of the front of the travel seat 94. The contact groove 95 has ratchet teeth inside, and these ratchet teeth correspond to the ratchet teeth on the front of the locking block 862. A coupling seat 96 is provided at the top and bottom near the end of the outer surface of the connecting socket 92. The coupling seat 96 is connected to the second push rod 75.

[0056] The device employs a technical solution where the connector plug 4 and connector socket 92 are initially separated. This allows the connector plug 4 to move closer to the connector socket 92 under water pressure, eventually connecting the connector plug 4 and connector socket 92. If the connector plug 4 and connector socket 92 were initially connected, the water pressure on the water seal travel plate 3 would directly act on the connection between the connector plug 4 and connector socket 92. As the water pressure increases, this could easily lead to excessive interaction force between the connector plug 4 and connector socket 92, causing damage. The initial separation technical solution effectively solves this problem and improves the practicality of the device.

[0057] Please see Figure 3 and Figure 11 The axis of the connector 4 and the axis of the connector 92 are located on the same center line.

[0058] The surface of the connection between the connector 4 and the connector 92 is provided with an anti-corrosion coating. The anti-corrosion coating adopts a combination of electroplated rhodium, ruthenium, platinum and palladium nickel. This can avoid the problem that the connector 4 and the connector 92 are prone to electrolytic corrosion due to being underwater and in a humid environment, which can damage the structure of the connector 4 and the connector 92 and affect the quality of data transmission, thus improving the reliability of the device.

[0059] Please see Figure 8 and Figures 10-11 Under pressure, the locking block 862 extends out from the inside of the strip hole 84, and the ratchet on the front of the locking block 862 contacts the ratchet inside the contact groove 95. At this time, the two stroke devices 9 can only move in directions away from each other.

[0060] When the device is underwater, water pressure acts on the inside of the pressure-conducting chamber 85 through the pressure-conducting pipe 77 and the connection port 87, thereby pushing the locking device 86 to extend from the inside of the slot 84. After the locking device 86 extends, the ratchet on the front of the locking block 862 engages with the ratchet inside the contact groove 95, thereby preventing unstable water pressure inside the pressure-conducting chamber 85. The travel device 9 resets under the elastic force of the return spring 88, which would otherwise cause unstable connection between the connector plug 4 and the connector socket 92, thus improving the stability of the device. In addition, when the device needs maintenance, the operator can retrieve the device from the water. The pressure inside the pressure-conducting chamber 85 will disappear, and the locking device 86 will reset under the action of the pressure spring 863, causing the ratchet on the front of the locking block 862 to disengage from the ratchet inside the contact groove 95. This allows the travel device 9 to reset under the elastic force of the return spring 88, ensuring that the connector socket 92 and the connector plug 4 can be separated. This facilitates maintenance of the device and improves its reliability.

[0061] When the device is used in a non-underwater environment, a rod can be inserted into the top of the threaded sleeve 71. The rod engages with the inside of the threaded sleeve 71, and the bottom of the rod contacts the top surface of the telescopic rod 74. During the insertion of the rod into the threaded sleeve 71, the bottom of the rod pushes the telescopic rod 74 downward and moves the travel device 9 away from each other. At the same time, the threaded sleeve 71 is rotated, causing the annular slide plate 73 to move closer to each other. This also causes the water seal travel plate 3 and the connector 4 to move closer to each other. After the above operations, the connector 4 and the connector socket 92 can be used in non-underwater conditions, improving the practicality of the device.

[0062] The method of using this invention is as follows:

[0063] When the device is underwater, the water pressure on its outer surface increases with depth. During this process, the water-sealed travel plate 3 moves continuously along the axis of the travel sleeve 2 under water pressure. The device employs a technical solution where the connector 4 and connector 92 are initially separated, allowing the connector 4 to move closer to the connector 92 under water pressure, ultimately connecting the connector 4 and connector 92. When the device is at a shallow depth, the threaded sleeve 71 can be rotated before use, causing it to move upwards, while the annular slide plate 73 moves towards each other. The distance between the annular sliding plate 73 and the connecting plug 4 increases, and under the traction of the balance spring 5, the water seal travel plate 3 and the connecting plug 4 move closer to the connecting socket 92. This reduces the pressure on the water seal travel plate 3 when the connecting plug 4 and the connecting socket 92 are connected, allowing the device to operate normally at shallow depths. Similarly, rotating the threaded sleeve pipe 71 in the opposite direction increases the pressure on the water seal travel plate 3 when the connecting plug 4 and the connecting socket 92 are connected, allowing the device to be adjusted appropriately according to the depth of its location. When the device is underwater, the water pressure... Simultaneously, the pressure acts on the top of the telescopic rod 74, causing it to move downwards. During this process, the second push rods 75 on both sides push the two travel devices 9 to move away from each other, thereby shortening the distance between the connector plug 4 and the connector socket 92. This ensures that after the connector plug 4 is displaced under water pressure, the connector plug 4 and the connector socket 92 can be stably connected. When the device is underwater, the water pressure acts on the inside of the pressure-conducting chamber 85 through the pressure-conducting pipe 77 and the connection port 87, thereby pushing the locking device 86 to extend from the inside of the slot 84. After the locking device 86 extends, the ratchet on the front of the locking block 862 contacts the inside of the contact groove 95. The ratchet mechanism is designed to prevent unstable water pressure inside the pressure chamber 85. The travel device 9, under the force of the return spring 88, resets, preventing instability in the connection between the connector 4 and the connector socket 92. This improves the stability of the device. Furthermore, when the device needs maintenance, the operator retrieves it from the water, the pressure inside the pressure chamber 85 disappears, and the locking device 86 resets under the action of the pressure spring 863. This causes the ratchet on the front of the locking block 862 to disengage from the ratchet inside the contact groove 95, allowing the travel device 9 to reset under the force of the return spring 88, thus ensuring that the connector socket 92 and the connector 4 can be separated.

[0064] When the device is used in a non-underwater environment, a rod can be inserted into the top of the threaded sleeve 71. The rod engages with the inside of the threaded sleeve 71, and the bottom of the rod contacts the top surface of the telescopic rod 74. During the insertion of the rod into the threaded sleeve 71, the bottom of the rod pushes the telescopic rod 74 downward and drives the travel device 9 to move away from each other. At the same time, the threaded sleeve 71 is rotated, which drives the annular slide plate 73 to move closer to each other, and at the same time drives the water seal travel plate 3 and the connecting plug 4 to move closer to each other.
