[0002] Watertight cables are specially designed cables for power transmission or signal transmission in wet, flooded or high water pressure environments. They are waterproof, moisture-proof and water-pressure-proof, and can provide reliable power or signal transmission performance. Watertight cables are widely used in underwater power transmission, submarine communications, underwater photography and other fields. They can provide stable and reliable power supply or signal transmission in harsh underwater environments, providing important support for marine engineering, underwater exploration and other underwater applications.

[0003] At present, when water contains chemicals such as acids, alkalis, and solvents, cables may face the problem of water penetration caused by erosion and wear of the outer layer. This may cause damage to the core of the optical fiber, wire, etc., making the cable unable to work properly. In addition, after the outer layer is damaged, the overall compression resistance of the cable will be reduced. When the external pressure is too large and the cable is bent, the cable core is prone to breakage. Utility Model Content

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 As shown, in an embodiment of the utility model, a high water pressure resistant composite watertight cable comprises a conductor core 1, a power line core 2, a signal transmission line core 3, and a protective structure arranged outside the conductor core 1, the power line core 2, and the signal transmission line core 3, wherein the protective structure comprises:

[0024] Three sets of rubber sleeves 4 are respectively sleeved on the outside of the conductor fiber core 1, the power line core 2, and the signal transmission line core 3;

[0025] A reinforcing fiber layer 5 is disposed between the conductor core 1, the power line core 2, and the signal transmission line core 3, and is used to support the conductor core 1, the power line core 2, and the signal transmission line core 3. A plurality of hole groups 8 are formed on the reinforcing fiber layer 5, and the hole groups 8 are used to maintain the pressure inside and outside the cable;

[0026] A pressure-resistant layer 6, wrapped around the conductor core 1, the power line core 2, and the signal transmission line core 3;

[0027] The outer protective layer 7 is wrapped around the outer side of the pressure-resistant layer 6 .

[0028] As part of the protective structure, the rubber sleeve 4 is sleeved on the outside of the conductor core 1, the power core 2 and the signal transmission core 3 to provide additional protection. The rubber sleeve 4 can prevent external wear and tear and protect the core components inside the cable. The rubber sleeve 4 has good flexibility and wear resistance and can withstand the pressure and friction of the external environment.

[0029] The reinforcing fiber layer 5 is located between the conductor core 1, the power core 2 and the signal transmission core 3, and is used to support and reinforce these cores. A plurality of hole groups 8 are provided on the reinforcing fiber layer 5, which are used to maintain the pressure balance inside and outside the cable. The reinforcing fiber layer 5 has high tensile strength and corrosion resistance, and can improve the structural strength and stability of the cable. The setting of the hole group 8 helps to maintain the pressure balance inside and outside and reduce the impact on the core structure.

[0030] The pressure-resistant layer 6 is wrapped around the outside of the conductor core 1, the power core 2 and the signal transmission core 3, and adopts a structure of polyamide plus metal mesh to provide pressure resistance. The pressure-resistant layer 6 has good pressure resistance, can withstand external pressure, and protect the core from damage. The combination of polyamide and metal mesh makes the pressure-resistant layer 6 have high strength and stability.

[0031] The outer sheath 7 is located outside the compression layer 6 to provide additional protection and wear resistance. The outer sheath 7 can effectively resist wear and damage from the external environment and extend the service life of the cable.

[0032] First, the conductor core 1, the power core 2 and the signal transmission core 3 are respectively wrapped in a rubber sleeve 4 to provide additional protection. Then, under the support of the reinforcing fiber layer 5, the cores wrapped in the rubber sleeve 4 are placed together and supported by the filling layer 10. The filling layer 10 is used to maintain the position of the cores and fix the interval between the cores.

[0033] Subsequently, the pressure-resistant layer 6 is wrapped around the outside of the core to provide the cable with pressure-resistant performance. The pressure-resistant layer 6 is usually made of a polyamide plus metal mesh structure, which has strength and stability.

[0034] Finally, the outer sheath 7 is wrapped around the outside of the compression layer 6 to provide additional protection and wear resistance for the cable.

[0035] During the entire assembly process, pay attention to maintaining the correct position and order of each component to ensure the integrity and functionality of the cable. After assembly, the cable has good pressure resistance, watertightness and durability, and is suitable for power transmission and signal transmission needs in high water pressure environments.

[0036] like Figure 2 As shown, in the embodiment of the utility model, the hole group 8 includes two through holes 9, and the through holes 9 are spirally arranged, and the two through holes 9 intersect with each other.

[0037] By this arrangement, the balance of internal and external pressures can be maintained. The through hole 9 can be designed on the reinforcing fiber layer 5. Through the through hole 9, the internal and external pressures can be balanced, avoiding damage or leakage problems caused by pressure differences. At the same time, the spiral arrangement can prevent the pressure-bearing capacity of the reinforcing fiber layer 5 from being too weak in this part, thereby improving the strength.

[0038] In the embodiment of the utility model, a filling layer 10 is provided between the pressure-resistant layer 6 and the reinforcing fiber layer 5 , and the filling layer 10 is used to provide support for the conductor core 1 , the power line core 2 , and the signal transmission line core 3 .

[0039] In the embodiment of the utility model, the pressure-resistant layer 6 is a structure of polyamide and metal mesh.

[0040] In the embodiment of the present utility model, the reinforcing fiber layer 5 is a glass fiber structure.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
