Description
A multi-core cable for submersible equipment Technical Field
[0001] This utility model relates to the field of cable technology, and in particular to a multi-core cable for submersible equipment. Background Technology
[0002] With the continuous development of marine resource development, underwater engineering construction and diving sports, the application of diving equipment is becoming more and more widespread. These devices require multi-core cables to realize power transmission, signal control and data communication. For example, in deep-sea submersibles, multi-core cables are needed to provide power and transmit signals and control commands from various sensors to ensure the normal operation of the submersible and data acquisition.
[0003] A search revealed Chinese Patent Publication No. CN210378575U, which discloses a multi-core cable, relating to the field of cables. The cable includes an insulating sheath, with a foam sleeve fixedly fitted onto the inner wall of the first insulating sheath. Symmetrical through holes are opened on the front of the foam sleeve, and a cutting wire is fixedly fitted into the inner cavity of each through hole. A first shielding mesh is fixedly fitted into the inner cavity of the foam sleeve. Multiple conductor groups are arranged within the inner cavity of the first shielding mesh. A carrying device is arranged within the inner cavity of the first shielding mesh, and the carrying device is located between the multiple conductor groups. A filling block is filled into the inner cavity of the first shielding mesh. The outer wall of the sleeve is coated with paint, and the conductor group includes multiple copper wires. This utility model utilizes a cutting wire setting method, in which the cutting wire is fixedly connected to the foam layer. When the insulating sheath is cut, pulling the cutting wire can cut the insulating sheath, and then the insulating sheath can be peeled off. This not only improves the stripping efficiency but also avoids damage to the internal components of the cable. However, this utility model does not consider that when the cable is subjected to external impact or compression, if there is no sufficient protection for the internal structure, it will lead to damage to the internal structure, thereby affecting the normal use of the entire cable. Summary of the Invention
[0004] To overcome the above deficiencies, this utility model provides a multi-core cable for submersible equipment, aiming to improve the problem in the prior art where insufficient internal protection can lead to damage to the internal structure, thereby affecting the normal use of the entire cable.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-core cable for submersible equipment, comprising a conductor, with limiting rings fixedly connected to the left and right sides of the outer wall of the conductor, an insulating layer fixedly connected to the outer wall of the limiting ring, a protective layer fixedly connected to the outer wall of the insulating layer, a waterproof layer fixedly connected to the outer wall of the protective layer, an installation layer fixedly connected to the outer wall of the waterproof layer, a plurality of elastic sheets fixedly connected to the outer wall of the installation layer, an elastic block fixedly connected to the bottom of the elastic sheet, a sheath fixedly connected to the outer wall of the elastic sheet, and a sealing mechanism provided on the outer wall of the conductor for sealing the cable connection.

The presence of the protective layer further enhances the conductor's resistance to wear and chemical corrosion.

[0044] Specifically, the mounting block 11 not only firmly supports the entire structure, but is also fixedly connected to the elastic sheet 8, ensuring that the elastic sheet 8 can effectively absorb and disperse the impact force when subjected to external force, thereby protecting the internal components from damage.

[0047] Working principle: Multiple conductors 1 are bound together by limiting rings 3, which improves the electrical performance and mechanical strength of the entire device. Insulation layer 4 can prevent current leakage. Protective layer 5 provides full protection for internal conductors 1. Waterproof layer 6 can prevent external water from penetrating into the interior and causing structural failure. Installation layer 7 provides great convenience for the installation of elastic sheet 8 and elastic block 9. When the outside is impacted, the external impact will contact the sheath 10, and then the sheath 10 will squeeze the elastic sheet 8. The elastic sheet 8 will then apply pressure to the elastic block 9. Since the elastic sheet 8 and elastic block 9 have elasticity, they can buffer and offset the external impact and prevent damage to the internal conductors 1.
[0048] After connecting the two cables, push the semicircular blocks 203 and 204 to rotate them around the outer wall of the shaft 202, and press the fixing blocks 205 and 206 together tightly. The sealing block 12 will then compress and seal the connection. Then, tighten the screw 207 so that it passes through the fixing blocks 206 and 205 to fix them together. This will seal the cable connection and prevent external water from entering the cable and damaging its internal structure.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
