Description

Technical Field

[0001] This application relates to the field of cable connection sealing technology, and in particular to a cable waterproofing component and an underwater vehicle. Background Technology

[0002] As the application scenarios of electronic devices, industrial equipment, and new energy facilities become increasingly demanding (such as deep-sea exploration, outdoor communication base stations, and new energy vehicle charging interfaces), the waterproof sealing performance of cable connections has become a core element in ensuring the stable operation of equipment.

[0003] Traditional cable waterproofing components achieve sealing by compressing the cable surface with the deformation of elastic materials (such as rubber and silicone). However, they frequently fail to provide waterproofing under dynamic environments such as high pressure, temperature difference, and vibration, leading to equipment short circuits, signal interference, and even safety accidents. Utility Model Content

[0004] This application provides a cable waterproofing component and an underwater vehicle to address the problem of insufficient waterproofing performance of current cable waterproofing components in some dynamic and complex scenarios.

[0005] To solve the above-mentioned technical problems, one technical solution adopted in this application is to provide a waterproof cable assembly, which includes: a cable; an outer sleeve including a connected access cavity and an installation cavity; an inner liner covering the cable and installed in the installation cavity to form a sealing fit with the inner wall of the installation cavity; and fasteners connected to the outer sleeve for fixing the inner liner in the installation cavity.

[0006] In some embodiments, the inner liner is provided with a through hole for the cable to pass through and is interference-fitted with the cable, the access cavity is used to seal the terminal of the external device, and one end of the cable passing through the through hole is connected to the terminal.

[0007] In some embodiments, the cable is integrally formed with the liner.

[0008] In some embodiments, the outer wall of the liner is provided with at least one annular sealing rib, which is in close contact with the inner wall of the mounting cavity.

[0009] In some embodiments, the outer wall of the liner is provided with at least two annular sealing ribs; the outer wall of the liner is provided with at least one first annular sealing groove, and the cable waterproofing assembly further includes a sealing ring disposed in the first annular sealing groove. The sealing ring is assembled together with the liner into the mounting cavity and forms an interference seal with the inner wall of the mounting cavity.

[0010] In some embodiments, the first annular sealing groove is disposed between two adjacent annular sealing ribs, and the sealing ring and the annular sealing rib together form a multiple sealing structure with the inner wall of the mounting cavity; the number of sealing rings is less than or equal to the number of the first annular sealing grooves.

[0011] In some embodiments, the inner wall of the mounting cavity is further provided with a slot, and the fastener is a retaining spring, which is inserted into the slot and stops the inner liner from being placed in the mounting cavity.

[0012] In some embodiments, the outer kit includes a baffle and a first cylinder and a second cylinder connected to both sides of the baffle. The first cylinder has the access cavity, and the second cylinder has the mounting cavity. The baffle has a through hole that communicates with the access cavity and the mounting cavity. The slot is located on the inner wall of the second cylinder. The baffle also blocks the end of the inner liner that is away from the retaining spring.

[0013] In some embodiments, the inner wall of the first cylinder is provided with at least one second annular sealing groove, the second annular sealing groove being used to install a sealing ring to form a sealed connection with the wiring terminal of an external device; the outer wall of the first cylinder is provided with multiple locking grooves.

[0014] To solve the aforementioned technical problems, another technical solution adopted in this application is to provide an underwater vehicle. This underwater vehicle includes a vehicle body and a waterproof cable assembly as described above. The access cavity of the outer casing is sealed to a terminal on the vehicle body, and the cable is connected to the terminal.

[0015] The beneficial effects of this application are as follows: Unlike the prior art, this application discloses a waterproof cable assembly and an underwater vehicle. By setting an inner liner to cover the cable and installing the inner liner inside the mounting cavity, forming a sealed fit with the inner wall of the mounting cavity, and using fasteners connected to the outer assembly, the inner liner is limited and fixed within the mounting cavity. This ensures a sealed fit between the inner liner and the inner wall of the mounting cavity, effectively preventing liquid ingress and ensuring the connection and sealing stability between the cable and external equipment. The fasteners prevent the inner liner from shifting due to vibration or pressure changes within the mounting cavity, further enhancing the reliability and durability of the overall structure and preventing the inner liner from falling off. This makes it suitable for complex underwater environments. Attached Figure Description

[0025] This application provides a cable waterproofing assembly 100, in conjunction with reference to [reference needed]. Figures 1 to 3 , Figure 1 This is a structural schematic diagram of an embodiment of the cable waterproofing assembly provided in this application. Figure 2 yes Figure 1 The diagram shown is an exploded view of the cable waterproofing assembly. Figure 3 yes Figure 1 The diagram shows a cross-sectional view of the cable waterproofing assembly along the AA direction.

[0026] like Figure 1 The diagram shows a structural schematic of an embodiment of the waterproof cable assembly provided in this application. The waterproof cable assembly 100 includes an outer sleeve 10, an inner liner 20, fasteners 30, and a cable (not shown). The outer sleeve 10 includes a connected access cavity 101 and a mounting cavity 102. The inner liner 20 covers the cable 100. The inner liner 20 is installed in the mounting cavity 102 and forms a sealed fit with the inner wall of the mounting cavity 102. The fasteners 30 are connected to the outer sleeve 10 and are used to fix the inner liner 20 in the mounting cavity 102. The outer sleeve 10 can be sealed to an external device. In use, the connection end of the cable can be located in the access cavity 101, and the terminal of the external device can be connected to the connection end of the cable in the access cavity 101.

[0027] The external device can be an underwater vehicle, underwater camera, underwater sensor, or other equipment that needs to transmit data or supply power in an underwater environment. These devices typically require connection to an external power source, control system, or data acquisition system via cables. However, due to the unique nature of the underwater environment, moisture can easily seep in through gaps between the cable and the device's terminals, leading to equipment damage or data transmission failure. Therefore, the waterproof cable assembly 100 provided by this invention effectively solves this problem, ensuring the normal operation of underwater equipment and the stability of data transmission. Furthermore, the waterproof cable assembly 100 is simple and practical in design, easy to install and disassemble, and convenient for users to maintain and replace.

[0028] The inner liner 20 is provided with a cable pass-through hole 201 for cable to pass through and is interference fit with the cable. The access cavity 101 is used to seal the terminal of the external device. One end of the cable passing through the cable pass-through hole 201 is connected to the terminal.

[0029] In this application, the outer sleeve 10 is designed with two interconnected cavities: an access cavity 101 and a mounting cavity 102. The access cavity 101 is used for a sealed connection with the wiring terminals of an external device, while the mounting cavity 102 provides a mounting position for the inner liner 20. The inner liner 20 has a wire-passing hole 201 inside, the size of which is interference-fitted with the cable to ensure a good seal when the cable passes through. The inner liner 20 is installed inside the mounting cavity 102, forming a sealed fit with the inner wall of the mounting cavity 102 to prevent moisture intrusion. Fasteners 30 are connected to the outer sleeve 10, and their main function is to firmly fix the inner liner 20 within the mounting cavity 102, ensuring that the inner liner 20 does not shift during use, thereby maintaining a sealed state between the cable and the inner liner 20.

[0030] In practical applications, one end of the cable passes through the through hole 201 and connects to the terminal of the external device. The access cavity 101 ensures the sealing of this connection point, effectively preventing damage to the connection point from external factors such as water and other impurities.

[0031] By adopting the above design for the cable waterproofing component 100, it can effectively prevent water penetration in deep water environments. Furthermore, by replacing the inner liner 20 with cable holes 201 of different sizes and shapes, it can adapt to cables of different sizes and shapes, thus improving the versatility and flexibility of the cable waterproofing component 100 in adapting to various types of cables.

[0032] Meanwhile, the cable and the inner liner 20 have an interference fit in the cable pass-through hole 201, and the inner wall of the mounting cavity 102 is tightly bonded to the inner liner 20, further enhancing the waterproof effect between the cable and the cable waterproof assembly 100. Through this double-sealing design, the cable waterproof assembly 100 can effectively improve the waterproof performance and reliability of the connection, thereby ensuring that the cable can reliably transmit data and / or provide stable power, maintaining efficient equipment operation even in extreme deep-water environments, extending service life, and reducing maintenance costs.

[0033] Furthermore, the cable waterproof assembly 100 is made of corrosion-resistant and high-pressure-resistant materials, making it suitable for deep-water environments and ensuring long-term stable operation. Its compact structure occupies little space and does not affect the overall equipment layout, making it widely applicable in fields such as marine exploration and underwater engineering, significantly improving operational efficiency and equipment safety.

[0034] The outer sleeve 10 can be made of a rigid material or a material with a certain degree of rigidity, such as rubber or plastic, to ensure a good seal between the access cavity 101 and the wiring terminal of the external device. The shape and size of the mounting cavity 102 are designed to match the inner liner 20, so that the inner liner 20 can be securely installed in the mounting cavity 102.

[0035] In this embodiment, the outer casing 10 includes a baffle 12 and a first cylindrical body 14 and a second cylindrical body 16 connected to both sides of the baffle 12. The first cylindrical body 14 has an access cavity 101, and the second cylindrical body 16 has an installation cavity 102. The baffle 12 has a through hole 103, which communicates with the access cavity 101 and the installation cavity 103. The dimensions and thicknesses of the first cylindrical body 14 and the second cylindrical body 16 can be specifically set based on the applicable scenario, and this application does not impose specific limitations on them.

[0036] The diameter of the wire hole 201 of the inner liner 20 is slightly smaller than the outer diameter of the cable, thereby achieving an interference fit, preventing the cable from loosening in the wire hole 201 and achieving a waterproof function.

[0037] The material of the inner liner 20 can be an elastic material to ensure that a good sealing effect can be formed between the wire hole 201 and the cable, as well as between the inner liner 20 and the inner wall of the mounting cavity 102, to prevent moisture from seeping in from the wire hole 201.

[0038] Alternatively, the inner liner 20 can also be made of a rigid material, which can utilize the material elasticity of the cable itself to achieve an interference fit, enhance the sealing performance, and the inner liner 20 and the inner wall of the mounting cavity 102 can be sealed by using auxiliary sealing structures such as sealing rings.

[0039] Furthermore, the outer wall of the inner liner 20 is provided with at least one annular sealing rib 21. The annular sealing rib 21 is in close contact with the inner wall of the mounting cavity 102, which can achieve a sealing fit between the inner liner 20 and the inner wall of the mounting cavity 102. The design of the annular sealing rib 21 enhances the fit between the inner liner 20 and the mounting cavity 102 and effectively prevents moisture penetration.

[0040] The outer wall of the inner liner 20 can be provided with multiple layers of annular sealing ribs 21 to further enhance the sealing effect and adapt to different pressure environments. Each layer of annular sealing ribs 21 should be reasonably spaced to ensure layered protection, further improving waterproof performance and ensuring stable waterproofing at the connection points of cables and external equipment in complex underwater environments.

[0041] Furthermore, the outer wall of the inner liner 20 also has at least one first annular sealing groove 22, and the cable waterproof assembly 100 further includes a sealing ring 40 disposed within the first annular sealing groove 22; wherein, the number of sealing rings 40 may be less than or equal to the number of first annular sealing grooves 22. The sealing ring 40 is assembled together with the inner liner 20 into the mounting cavity 102 and forms an interference seal with the inner wall of the mounting cavity 102 to further improve the sealing effect and enhance waterproof reliability.

[0042] The first annular sealing groove 22 is disposed between two adjacent annular sealing ribs 21. The sealing ring 40 and the annular sealing ribs 21 together form a multi-layer sealing structure with the inner wall of the mounting cavity 102. This multi-layer sealing structure can effectively prevent liquid intrusion, ensuring that the cable maintains a stable connection and reliable waterproof performance under dynamically changing water pressure.

[0043] Fastener 30 can be connected to the outer sleeve 10 by threaded connection, snap-fit ​​connection or other suitable connection method. The design of fastener 30 should ensure that the inner liner 20 is securely fixed in the mounting cavity 102, while facilitating disassembly and replacement.

[0044] During use, the cable is first passed through the cable threading hole 201 of the inner liner 20, and then the inner liner 20 is installed into the mounting cavity 102 of the outer kit 10. Next, the access cavity 101 of the outer kit 10 is sealed and connected to the terminal of the external device, and the inner liner 20 is fixed in the mounting cavity 102 using fasteners 30. In this way, the cable waterproof assembly 100 can effectively prevent moisture from seeping in from the terminal, protecting the normal operation of the cable and equipment.

[0045] In this embodiment, the fastener 30 is a retaining spring, and the inner wall of the mounting cavity 102 is also provided with a retaining groove 160, that is, the retaining groove 160 is located on the inner wall of the second cylinder 16. The retaining spring is inserted into the retaining groove and stops the inner liner 20 in the mounting cavity 102. The baffle 12 also stops the end of the inner liner 20 away from the retaining spring. The retaining spring is tightly connected to the outer sleeve 10 through the retaining groove, ensuring that the inner liner 20 is stable and does not move in the mounting cavity 102. At the same time, the design of the baffle 12 effectively prevents the inner liner 20 from accidentally slipping out during disassembly, improving the stability and safety of the overall structure. The elastic tension of the retaining spring can also be adjusted according to the size of the inner liner 20, thereby ensuring a tight fit and avoiding waterproof failure due to loosening. In other embodiments, the fastener can also take the form of nuts, bolts, washers, gaskets, and pins, etc., depending on the specific application scenario, stress requirements, and anti-loosening requirements. This application does not make specific limitations in this regard.

[0046] The inner wall of the first cylinder 14 is provided with at least one second annular sealing groove 140. The second annular sealing groove 140 is used to install a sealing ring to form a sealed connection with the wiring terminal of the external device, thereby enhancing the sealing effect between the access cavity 101 and the wiring terminal and ensuring the waterproof performance of the connection between the cable and the external device.

[0047] The number of second annular sealing grooves 140 can be one or more, depending on actual needs. Their depth and width should match the corresponding sealing ring to ensure full compression and sealing effect of the sealing ring.

[0048] The outer wall of the first cylinder 14 is provided with a multi-ring locking groove 142. The multi-ring locking groove 142 is used to secure the outer kit 10 to the external device with the help of an external locking tool, thereby enhancing the connection stability, preventing it from falling off the wiring terminal of the external device, and also enhancing the sealing performance between the first cylinder 14 and the wiring terminal of the external device.

[0049] See also Figure 4 and Figure 5 , Figure 4 This application provides a structural schematic diagram of another embodiment of the cable waterproofing assembly; Figure 5 yes Figure 4 The diagram shows an exploded view of the waterproof cable assembly 200. The waterproof cable assembly 200 includes an outer sleeve 210, an inner liner 220, fasteners 230, and a cable 240. The difference between this embodiment and the previous embodiment is that the inner liner 220 does not have a threading hole; instead, it is injection molded onto the outside of the cable 240, meaning the cable 240 and the inner liner 220 are integrally formed. The structural designs of the outer sleeve 210 and the fasteners 230 are the same as in the previous embodiment. Except for the features related to the threading hole, the other structural features of the inner liner 220 are also consistent with the previous embodiment, and therefore will not be repeated here.

[0050] It is understandable that, in embodiments where the cable and inner liner are designed as a single unit, during use, the access cavity of the outer kit can be directly and sealed to the wiring terminal of the external device, and the inner liner can be fixed in the mounting cavity using fasteners.

[0051] In this application, the access cavity 101 of the outer kit 10 can form a good sealing and anti-loosening and anti-detachment structure with the wiring terminal of the external device, thereby ensuring the waterproof performance and connection stability at the wiring terminal, so as to be suitable for a variety of complex underwater environments; the multi-seal structure design between the mounting cavity 102 and the inner liner 20, and the tight connection between the inner liner 20 and the cable, effectively prevent liquid ingress, so that the cable waterproof assembly 100 can still maintain excellent waterproof performance under dynamic water pressure, effectively ensuring the stability and safety of the cable connection, and ensuring the normal operation of the equipment in harsh environments.

[0052] Based on this, this application also provides an underwater vehicle (not shown), which includes a vehicle body and a cable waterproofing assembly as described above, wherein the access cavity of the outer kit is sealed to a terminal on the vehicle body, and the terminal is connected to the cable.

[0053] The underwater vehicle body, as the main structure of the underwater vehicle, includes not only the control terminal but also components for performing specific functions. For example, it may have components related to search and rescue, pipeline maintenance, and energy exploration; it may also have observation components such as cameras, video cameras, and lighting; and it may be equipped with operational components such as robotic arms, cutters, and cleaners. In this embodiment, the specific functions and components of the underwater vehicle body are not limited.

[0054] The waterproof cable assembly can connect to the wiring terminals of the vessel body, providing stable power and data transmission to the vessel body and ensuring its efficiency and reliability during underwater operations.

[0055] Unlike existing technologies, this application discloses a waterproof cable assembly and an underwater vehicle. By designing an inner liner to cover the cable and to be installed within a mounting cavity, forming a sealed fit with the inner wall of the cavity, and using fasteners connected to the outer casing, the inner liner is secured within the mounting cavity. This seal effectively prevents liquid ingress, ensuring stable connection and sealing between the cable and external equipment. The fasteners prevent the inner liner from shifting due to vibration or pressure changes within the mounting cavity, further enhancing the overall structural reliability and durability, and preventing the inner liner from detaching. This design is suitable for complex underwater environments.

[0056] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
