Abstract
Description
Technical Field
[0001] This utility model relates to the field of watertight cable technology, specifically a wiring device for a transverse watertight cable. Background Technology
[0002] Watertight cables are special cables designed specifically for underwater environments. Their core feature is their excellent waterproof sealing performance, which effectively prevents moisture, humidity, and various liquid media from penetrating into the cable's interior. Through special structural design and material selection, such as sealants, rubber seals, multi-layer waterproof sheaths, and special waterproof joints, these cables ensure long-term stable operation in various underwater environments, unaffected by moisture erosion. Watertight cables are widely used in marine engineering, underwater exploration, submarine communications, offshore wind power, oil and gas extraction, and other fields, providing safe and reliable power and signal transmission guarantees for these fields. They are an indispensable key infrastructure for underwater activities.
[0003] Based on existing watertight cables, it has been found that during splicing, the cable insulation sheath needs to be cut open to connect the wires. However, in subsequent splicing operations, the wires at the splice point cannot be effectively protected. Over long-term operation, the wires at the splice point may be exposed to water, leading to leakage problems. In addition, because watertight cables need to withstand complex mechanical stresses in marine or underwater environments, such as water flow impact and seabed friction, if the splice point is not effectively protected, mechanical damage such as tearing may occur. These unexpected situations not only threaten the reliability and safety of the cable, but may also seriously affect the normal operation of underwater facilities.
[0004] Based on this, the present invention designs a wiring device for a transverse watertight cable to solve the above problems. Utility Model Content

Steel wires 305 are fixedly installed on the inner walls of both the first PP shell 301 and the second PP shell 302. The docking mechanism 3 also includes a docking plug 303 and a liquid injection pipe 306. A docking plug 305 is fixedly installed on the outer wall of the first PP shell 301 near the second PP shell 302. A plug block 303 is inserted into the second PP housing 302. A liquid injection pipe 306 is fixedly installed at the upper end of the first PP housing 301, extending inward into the interior of the first PP housing 301. A first threaded sleeve 307 is fixedly installed at both ends of the first cable 1, and a second threaded sleeve 308 is fixedly installed at both ends of the second cable 2. A first spiral sleeve 309 is provided on the left side of the first cable 1, and a first lever 310 is fixedly installed on the outer wall of the first spiral sleeve 309. The first spiral sleeve 309 is threadedly connected to the first threaded sleeve 307 and the second threaded sleeve 308 on the left side of the first PP housing 301 and the second PP housing 302. A second spiral sleeve 311 is provided on the right side of the second cable 2, and a second lever 312 is fixedly installed on the outer wall of the second spiral sleeve 311. The second spiral sleeve 311 is threadedly connected to the first threaded sleeve 307 and the second threaded sleeve 308 on the right side of the first PP housing 301 and the second PP housing 302.
[0028] See Figure 1 , Figure 4 , Figure 5 and Figure 7Initially, the docking mechanism 3 adopts a docking cap structure and a filling molding structure. The docking cap structure consists of a first PP shell 301, a second PP shell 302, a docking plug 303, a first threaded sleeve 307, a second threaded sleeve 308, a first spiral sleeve 309, a first lever 310, a second spiral sleeve 311, and a second lever 312. The filling molding structure consists of an insulating outer sheath 304, a steel wire body 305, and a liquid injection pipe 306. During installation, it is necessary to ensure that the insulating sheath at the connection between the first cable 1 and the second cable 2 is removed. Then, the wires 5 inside the first cable 1 and the second cable 2 are machined and docked. The insulating outer sheath 304 is wrapped around the wires 5 at the docking point of the first cable 1 and the second cable 2. Then, the first PP shell 301 and the second PP shell 302 are aligned and brought into close contact. Subsequently, the first cable 1 and the second cable 2 are removed from the limiting mechanism 4, and the first spiral sleeve 307, the second threaded sleeve 308, the first spiral sleeve 309, the second threaded sleeve 309, the first spiral sleeve 309, the second threaded sleeve 300, and the second threaded sleeve 300 are removed. 9 spiral sleeves are installed on the first threaded sleeve 307 and the second threaded sleeve 308 on the left side of the first PP shell 301 and the second PP shell 302, so that the left ends of the first PP shell 301 and the second PP shell 302 are fixedly connected. Then, the second spiral sleeve 311 is spirally installed on the first threaded sleeve 307 and the second threaded sleeve 308 on the right side of the first PP shell 301 and the second PP shell 302, thereby achieving the effect of connecting the first cable 1 and the second cable 2. Next, the silicone rubber is melted in the outside and filled into the inside of the first PP shell 301 and the second PP shell 302 through the injection pipe 306. After the silicone rubber cools down, the silicone rubber will wrap the insulating outer sheath 304 and the internal wire 5. The steel wire 305 combined with the silicone rubber effectively improves the overall toughness of the silicone rubber. In the later use, the steel wire 305 and the silicone rubber can play a high-strength connection function to ensure the connection reliability of the first cable 1 and the second cable 2.

The use of the insulating outer sheath 304 provides additional insulation protection for the cable body 5, reducing the risk of electrical faults and improving circuit safety. The combination of steel wire 305 and silicone rubber not only improves the overall toughness of silicone rubber, but also enhances the mechanical strength of the connection, ensuring the reliability of the cable connection. After curing, the filled silicone rubber provides excellent heat resistance, chemical resistance and aging resistance, extending the service life of the connection.

The first rubber pad 404 is provided below the first cable 1 and the second cable 2, and the second rubber pad 406 is provided above the first cable 1 and the second cable 2. The limiting mechanism 4 also includes a first mounting plate 403 and a second mounting plate 405. The first rubber pad 404 is fixedly installed on the first mounting plate 403, and the second rubber pad 406 is fixedly installed on the inner wall of the second mounting plate 405.

The threaded rod 407 passes downward through the first mounting plate 403, and a limiting nut 408 is provided on the outer side of the threaded rod 407.
[0031] See Figure 1 and Figure 8 When activated, the first cable 1 and the second cable 2 need to be placed on the first rubber pad 404 beforehand, and then the second mounting plate 405 and the second rubber pad 406 are pressed down to press the first cable 1 between the first rubber pad 404 and the second rubber pad 406. Then, the limit nut 408 is tightened so that the first rubber pad 404 and the second rubber pad 406 stably clamp the first cable 1, which facilitates the docking operation. The limit mechanism 4 adopts a clamping structure, which can quickly clamp the cable to be docked and ensure the stability of the cable during the docking process.
[0032] The working principle of this utility model is as follows: Upon activation, the first cable 1 and the second cable 2 need to be placed on the first rubber pad 404 beforehand. Then, the second mounting plate 405 and the second rubber pad 406 are pressed down, thereby pressing the first cable 1 between the first rubber pad 404 and the second rubber pad 406. Subsequently, the limiting nut 408 is tightened, so that the first rubber pad 404 and the second rubber pad 406 stably clamp the first cable 1, facilitating the docking operation. Next, the docking mechanism 3 is activated. The docking mechanism 3 adopts a docking sealing structure and a filling molding structure. The docking sealing structure consists of a first PP shell 301 and a second...

The filling molding structure consists of an insulating outer sheath 304, a steel wire body 305, and a liquid injection pipe 306. During installation, it is necessary to ensure that the insulating sheath at the connection between the first cable 1 and the second cable 2 is removed, and then the wires 5 inside the first cable 1 and the second cable 2 are mated. The insulating outer sheath 304 is then wrapped around the wires 5 at the connection between the first cable 1 and the second cable 2, and then the first PP outer shell is... The first PP housing 301 and the second PP housing 302 are brought into close contact. Then, the first cable 1 and the second cable 2 are removed from the limiting mechanism 4. The first spiral sleeve 309 is spirally installed on the first threaded sleeve 307 and the second threaded sleeve 308 on the left side of the first PP housing 301 and the second PP housing 302, thus fixing the left ends of the first PP housing 301 and the second PP housing 302 together. Finally, the second spiral sleeve 311 is spirally installed on the first threaded sleeve 308 on the right side of the first PP housing 301 and the second PP housing 302. 7. The first cable 1 and the second cable 2 are connected to the second threaded sleeve 308. Then, the silicone rubber is melted on the outside and filled into the inside of the first PP shell 301 and the second PP shell 302 through the injection pipe 306.
