Description

Technical Field

[0001] This utility model relates to the field of cable connection technology, specifically a quick pull-out structure for submarine cables. Background Technology

[0002] Submarine cables are cables used to transmit power or communication signals on the seabed. They are typically composed of multiple parts such as conductors, insulation layers, and protective layers. They have the characteristics of good insulation performance, strong compressive strength, and corrosion resistance, and can adapt to the complex conditions of the marine environment.

[0003] The plug connector includes a male plug and a female plug. When the operator plugs the male plug and the female plug together, they can easily come apart under the action of external force, which will affect the normal use of the power supply system.

[0004] The existing patent document with authorization announcement number CN222720788U describes an underwater cable pull-out structure, including a male plug and a female plug. The male plug has a first connecting block with several mating terminals, and the female plug has a second connecting block with several mating holes adapted to the mating terminals. This technical solution releases the lock between the male and female plugs by pressing an adjusting block to push a reset slider back into its return groove. Simultaneously, sliding the movable collar in the opposite direction facilitates the separation of the male and female plugs. However, when the adjusting block pushes the reset slider, the contact area between the adjusting block and the reset slider is small because the surface area of ​​the adjusting block is much smaller than that of the reset slider, affecting the stability during the pushing process. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a quick-release structure for submarine cables. This structure solves the problem that when the adjustment block pushes the reset slider, the contact area between the adjustment block and the reset slider is small because the surface area of ​​the adjustment block is much smaller than that of the reset slider, thus affecting the stability during the pushing process. By setting up a push plate, the contact area with the reset slider can be increased, thereby improving the stability when pushing the reset slider. Furthermore, the setting of a limiting inner ring restricts the sliding range of the slot post within the insertion groove, preventing the slot post from sliding out of the insertion groove.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid pull-out structure for submarine cables, comprising a male plug assembly, a female plug assembly, and a pull-out assembly. The male plug assembly includes a male plug body, and the female plug assembly includes a female plug body. The pull-out assembly includes a movable collar, an inner insertion groove, an insertion slide, and a slot post. One end of the male plug body is connected to a first connecting block. A first slot is formed on the inner side of the first connecting block away from the male plug body. A first insertion post is connected to the top of the first slot. A first sleeve is provided on the outer ring of the first insertion post. One end of the female plug body is connected to a retaining ring. A second connecting block is connected to the end of the retaining ring away from the female plug body. A second slot is formed on the inner side of the second connecting block away from the retaining ring. A second connecting block is formed on the inner side of the retaining ring. A compression spring is connected to the inner wall of the second connecting block. A reset slider is connected to the end of the compression spring away from the retaining ring wall. A push plate is connected to one end of the slot post.

[0007] The beneficial effects of this utility model are as follows: when the second connecting block is inserted into the first slot, the first insertion post is simultaneously inserted into the second sleeve along the central axis of the second sleeve, and at the same time, the first sleeve is inserted into the second slot along the central axis of the second slot, thereby forming a multi-layered, tightly interlocked connection. By setting the push plate, the contact area with the reset slider can be increased, thereby improving the stability when pushing the reset slider. By setting the limiting inner ring, the sliding range of the slot post in the insertion inner groove is limited, preventing the slot post from sliding out of the insertion inner groove.

[0008] In order for the first insertion post to be simultaneously inserted into the second sleeve along the central axis of the second sleeve:

[0009] As a further improvement to the above technical solution: when the second connecting block is inserted into the first slot, the first insertion post is simultaneously inserted into the second sleeve along the central axis of the second sleeve, and at the same time, the first sleeve is inserted into the second slot along the central axis of the second slot, thereby forming a multi-layered, tightly interlocked connection.

[0010] The beneficial effects of this improvement are as follows: when the male plug body is connected to the female plug body, the second connecting block is smoothly inserted along the central axis of the first slot, keeping it horizontal and without tilting during the insertion process, until the end face of the second connecting block is tightly fitted with the end face of the first connecting block. At this time, the first insertion post is simultaneously inserted into the second sleeve along the central axis of the second sleeve.

[0011] For the annular space reserved between the first sleeve and the first insertion post:

[0012] As a further improvement to the above technical solution: one end of the first sleeve is welded to the inner wall of the first slot, and the first insertion post coincides with the center of the first sleeve.

[0013] The beneficial effects of this improvement are as follows: by setting the first sleeve, the first sleeve can be inserted into the second slot during the connection process. At the same time, the inner diameter of the annular space reserved between the first sleeve and the first insertion post matches the outer diameter of the second sleeve, which is used for the insertion of the second sleeve.

[0014] In order for the first sleeve to be inserted into the second slot along the central axis of the second slot, thereby forming a multi-layered, tightly interlocking connection:

[0015] As a further improvement to the above technical solution: the inner wall of the second slot is connected to a second sleeve, the depth of the second slot is the same as the height of the second sleeve, and the second sleeve and the second connecting block are integrally formed.

[0016] The beneficial effects of this improvement are as follows: when the second connecting block is inserted into the first slot, the first plug post is simultaneously inserted into the second sleeve along the central axis of the second sleeve, and the first sleeve is inserted into the second slot along the central axis of the second slot, thus forming a multi-layered, tightly interlocked connection. This multi-layered connection structure ensures the stability of the connection between the male plug body and the female plug body. At the same time, since the first connecting block, the second connecting block, the first plug post, and the second sleeve are all standard cylindrical shapes with smooth surfaces, it is easy to pull out the connection after disconnection.

[0017] The movable collar is designed to seal and protect the connection between the first and second connecting blocks, preventing seawater intrusion.

[0018] As a further improvement to the above technical solution: the outer wall of the movable collar is symmetrically provided with a rubber anti-slip layer with raised texture on the surface, the movable collar is sleeved on the outer wall of the first connecting block and forms a sliding pair with it, and a limit ring is welded to the outer wall of the first connecting block.

[0019] The beneficial effects of this improvement are as follows: by setting the limiting ring, the sliding range of the movable collar on the outer wall of the first connecting block is limited, preventing the movable collar from sliding out of the first connecting block. By setting the movable collar, the connection between the first connecting block and the second connecting block is sealed and protected to prevent seawater intrusion.

[0020] To ensure that the reset slider is quickly and tightly inserted into the insertion slot under the elastic force of the compression spring:

[0021] As a further improvement to the above technical solution: the number of the insertion inner groove, the insertion slide groove, and the second connecting block are the same, and the second connecting block is symmetrically opened on both sides of the ferrule wall.

[0022] The beneficial effects of this improvement are as follows: When connecting the male plug body and the female plug body, the movable collar is first slid along the outer wall of the first connecting block to a predetermined position. The predetermined position makes the insertion groove on the movable collar aligned with the reset slider on the retaining ring. Then, the second connecting block is engaged with the first connecting block. During the engagement process, the connection is kept horizontal and without tilting until the reset slider is quickly and tightly inserted into the insertion groove under the elastic force of the compression spring.

[0023] To improve stability when pushing the reset slider:

[0024] As a further improvement to the above technical solution: the outer wall of the slot post is connected to a limiting inner ring, the limiting inner ring is disposed inside the insertion inner groove, and the limiting inner ring forms a sliding pair with the insertion inner groove through the slot post.

[0025] The beneficial effects of this improvement are as follows: by setting the push plate, the contact area with the reset slider can be increased, thereby improving the stability when pushing the reset slider; by setting the limiting inner ring, the sliding range of the slot post in the insertion inner groove is limited, preventing the slot post from sliding out of the insertion inner groove.

[0026] To allow the reset slider to slide completely out of the insertion slot, disconnect the retaining ring from the movable ring, which will then easily allow the cable to be pulled out.

[0027] As a further improvement to the above technical solution: the end of the slot post away from the push plate passes through the wall of the movable collar and is connected to a pull ring. The pull ring is connected to the slot post by welding. The push plate is set in the insertion groove. The push plate forms a sliding pair with the insertion groove through the slot post.

[0028] The beneficial effects of this improvement are as follows: When it is necessary to pull out the cable, the operator holds the pull ring and applies a steady force along the axial direction of the slot post. The force is transmitted to the push plate through the slot post. The push plate moves horizontally under the force and pushes the reset slider in the process. During the push, it remains horizontal and without tilting until the reset slider slides out of the insertion groove completely. At this time, the connection between the retaining ring and the movable ring is released, and the cable can be easily pulled out. Attached Figure Description

[0036] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0037] like Figure 1-6As shown, a quick-release structure for a submarine cable includes a male plug assembly 1, a female plug assembly 2, and a release assembly 3. The male plug assembly 1 includes a male plug body 11, and the female plug assembly 2 includes a female plug body 21. The release assembly 3 includes a movable collar 31, an inner insertion groove 33, an insertion slide groove 34, and a slot post 35. One end of the male plug body 11 is connected to a first connecting block 12. A first slot 13 is formed on the inner side of the first connecting block 12 away from the male plug body 11. A first insertion post 14 is connected to the top of the first slot 13. The outer ring is provided with a first sleeve 15. One end of the female plug body 21 is connected to a retaining ring 22. The end of the retaining ring 22 away from the female plug body 21 is connected to a second connecting block 23. A second slot 26 is opened on the inner side of the end of the second connecting block 23 away from the retaining ring 22. The inner side of the retaining ring 22 is provided with a second connecting block 23. A compression spring 24 is connected to the inner wall of the second connecting block 23. A reset slider 25 is connected to the end of the compression spring 24 away from the wall of the retaining ring 22. One end of the slot post 35 is connected to a push plate 37. The first insertion post 14 is... The device is a solid cylindrical structure. The first insertion post 14 is at the same height as the first sleeve 15, and the inner radius of the first slot 13 matches the outer radius of the second connecting block 23. When the male plug body 11 is connected to the female plug body 21, the second connecting block 23 is smoothly inserted along the central axis of the first slot 13, remaining horizontal and without tilting during insertion, until the end face of the second connecting block 23 is tightly fitted with the end face of the first connecting block 12. At this time, the first insertion post 14 is simultaneously inserted into the second sleeve 27 along the central axis of the second sleeve 27. The first sleeve 15... The first sleeve 14 is welded to the inner wall of the first slot 13, and the center of the first insertion post 14 coincides with the center of the first sleeve 15. Through the setting of the first sleeve 15, the first sleeve 15 can be inserted into the second slot 26 during the connection process. At the same time, the inner diameter of the annular space reserved between the first sleeve 15 and the first insertion post 14 matches the outer diameter of the second sleeve 27, which is used for the insertion of the second sleeve 27. The inner wall of the second slot 26 is connected to the second sleeve 27. The depth of the second slot 26 is the same as the height of the second sleeve 27. The second sleeve 27 and the second connecting block 23 are integrally formed.When the second connecting block 23 is inserted into the first slot 13, the first insertion post 14 is simultaneously inserted into the second sleeve 27 along the central axis of the second sleeve 27, and at the same time, the first sleeve 15 is inserted into the second slot 26 along the central axis of the second slot 26, thus forming a multi-layered, tightly interlocked connection. This multi-layered connection structure ensures the stability of the connection between the male plug body 11 and the female plug body 21. Furthermore, since the first connecting block 12, the second connecting block 23, the first insertion post 14, and the second sleeve 27 are all standard cylindrical shapes with smooth surfaces, they facilitate the pull-out operation after disconnection. The outer wall of the movable collar 31 is symmetrically provided with raised textures on its surface. A rubber anti-slip layer 32 is provided. The movable collar 31 is sleeved on the outer wall of the first connecting block 12 and forms a sliding pair with it. A limiting ring 16 is welded to the outer wall of the first connecting block 12. The limiting ring 16 is used to limit the sliding range of the movable collar 31 on the outer wall of the first connecting block 12, preventing the movable collar 31 from sliding out of the first connecting block 12. The movable collar 31 is also used to seal and protect the connection between the first connecting block 12 and the second connecting block 23, preventing seawater intrusion. The number of the insertion inner groove 33, the insertion sliding groove 34, and the second connecting block 23 are the same. The second connecting blocks 23 are symmetrically arranged on the wall of the retaining ring 22. On both sides; when connecting the male plug body 11 and the female plug body 21, first slide the movable collar 31 along the outer wall of the first connecting block 12 to a predetermined position, so that the insertion groove 34 on the movable collar 31 is aligned with the reset slider 25 on the retaining collar 22. Then, the second connecting block 23 is engaged with the first connecting block 12, keeping it horizontal and without tilting during the engagement process, until the reset slider 25 is quickly and tightly inserted into the insertion groove 34 under the elastic force of the compression spring 24. The outer wall of the slot post 35 is connected to a limiting inner ring 36, which is set in the insertion inner groove 33. The limiting inner ring 36 passes through the slot. The post 35 and the inner groove 33 form a sliding pair; the push plate 37 increases the contact area with the reset slider 25, thereby improving the stability when pushing the reset slider 25; the limiting inner ring 36 limits the sliding range of the slot post 35 in the inner groove 33, preventing the slot post 35 from sliding out of the inner groove 33; the end of the slot post 35 away from the push plate 37 passes through the wall of the movable collar 31 and is connected to a pull ring 38; the pull ring 38 is connected to the slot post 35 by welding; the push plate 37 is set inside the inner groove 34; the push plate 37 forms a sliding pair with the inner groove 34 through the slot post 35.When cable detachment is required, the operator holds the pull ring 38 and applies a steady force along the axial direction of the slot post 35. The force is transmitted to the push plate 37 through the slot post 35. The push plate 37 moves horizontally under the force, pushing the reset slider 25 in the process. The push plate remains horizontal and tilt-free until the reset slider 25 is completely slid out of the insertion groove 34. At this point, the connection between the retaining ring 22 and the movable ring 31 is released, allowing for easy cable detachment.

[0038] The working principle of this utility model is as follows: Before connecting the male plug assembly 1 and the female plug assembly 2, check whether each component is damaged. At the same time, clean the connecting surfaces of each component to remove any impurities or dirt to prevent them from affecting the connection effect and sealing. Insert the second connecting block 23 at one end of the female plug body 21 smoothly along the central axis of the first slot 13 until the end face of the second connecting block 23 is tightly fitted with the end face of the first connecting block 12. At this time, the first insertion post 14 will simultaneously insert into the second sleeve 27 along the central axis of the second sleeve 27, and the first sleeve 15 will also be inserted into the second slot 26, thus forming a multi-layered, tightly interlocked structure. This structure greatly improves the sealing performance. This ensures the stability of the connection between the male plug body 11 and the female plug body 21. Since the first connecting block 12, the second connecting block 23, the first insertion post 14, and the second sleeve 27 are all standard cylindrical shapes, this facilitates possible subsequent pull-out operations. After the initial connection of the male and female plug bodies is completed, the movable collar 31 is slid along the outer wall of the first connecting block 12. The outer wall of the movable collar 31 is symmetrically provided with a rubber anti-slip layer 32 with raised textures. The operator can use the good friction provided by the anti-slip layer 32 to control the sliding of the movable collar 31 to a predetermined position. This predetermined position must ensure that the insertion groove 34 on the movable collar 31 and the reset groove on the retaining ring 22 are properly aligned. The slider 25 is precisely aligned, and the limiting retaining ring 16 ensures that it can accurately slide to the predetermined position each time. When the movable collar 31 reaches the predetermined position, the reset slider 25, under the elastic force of the compression spring 24 inside the retaining ring 22, quickly and tightly inserts into the insertion groove 34, realizing the locking connection between the retaining ring 22 and the movable collar 31. At this time, the movable collar 31 not only completes the locking of the connection between the male plug body 11 and the female plug body 21, but also plays a role in sealing and protecting the connection, effectively preventing seawater intrusion and protecting the internal electrical connection components. At the same time, the limiting retaining ring 16 welded to the outer wall of the first connecting block 12 will restrict the movable collar 31 from the first connecting block 12. The sliding range of the wall prevents the movable collar 31 from accidentally sliding out of the first connecting block 12. When it is necessary to pull the cable out, the operator applies a steady force along the axial direction of the slot post 35 through the pull ring 38. The force applied by the operator is transmitted to the push plate 37 through the slot post 35. After being subjected to force, the push plate 37 moves horizontally in the insertion groove 34. During the movement, the push plate 37 will push the reset slider 25 evenly until the reset slider 25 completely slides out of the insertion groove 34. At this time, the connection between the retaining ring 22 and the movable collar 31 is released, and the operator can easily separate the male plug body 11 from the female plug body 21 to realize the cable pull-out operation.
