[0002] With the continuous advancement of science and technology, the application of computers in ships is becoming more and more extensive and popular. It not only provides convenience for daily office work on ships, but also provides necessary conditions for the safe production of ships, the improvement of work efficiency, and the standardization of ship operations. In recent years, with the development of network technology, especially the injection of local area networks, local area networks in ships have emerged, installed and used, which has facilitated the sharing of ship information resources and the transmission and transfer of data.

[0003] However, the ship environment is relatively humid, and data cables are easily soaked in water. When water changes from liquid to solid (i.e., freezes), its volume will expand many times. The huge pressure generated by the expansion of water when it is cold and frozen will cause the data cable to twist and deform, and its circular cross-section will be pressed into an irregular shape with uneven surfaces, and some may even cause core wire breakage or increased loss, resulting in significant signal attenuation, and finally causing transmission interruption or affecting the normal use of users. Therefore, the purpose of the present invention is to provide a moisture-proof shipboard data cable with an insulation structure to solve the problem that the existing data cables freeze when they are damp and cold, causing the data cables to freeze and twist, and even cause core wire breakage or increased loss. Summary of the invention

[0004] The object of the present invention is to provide a moisture-proof shipboard data cable with a heat-insulating structure to solve the problems raised in the above-mentioned background technology.

[0008] As a further improvement of the technical solution, the protective jacket is slidably installed in the slide groove through a limiting slider, and the protrusion is engaged with the anti-slip convex pattern.

[0009] As a further improvement of the technical solution, the positioning pressing block is tightly fitted to the surface of the sealing layer, and the sealing layer is made of aluminum foil heat insulation coil.

[0015] 2. In this moisture-proof marine data cable with an insulation structure, when the waterproof layer is damp and frozen, the waterproof layer is compressed and deformed. Due to the groove structure on the outside of the waterproof layer and the gap between the waterproof layer and the protective jacket, a certain deformation buffer space can be provided for the waterproof layer, thereby reducing the extrusion damage to the core layer.

[0036] Example 1

[0037] See also Figure 1-Figure 8 As shown, the purpose of this embodiment is to provide a moisture-proof marine data cable with an insulation structure, including a cable core 1, the outer wall of the cable core 1 is movably equipped with a protective jacket 2 for sealing the insulation layer, the cable core 1 includes a core layer and an insulation layer arranged outside the core layer, the insulation layer includes a waterproof layer 4, and the outer wall surface of the waterproof layer 4 is provided with a plurality of filling grooves 401, and the filling grooves 401 are filled with a mineral desiccant, the mineral desiccant contains diatomaceous earth, montmorillonite and other components, belongs to a porous mineral silicate, has a relatively large surface area, has an adsorption function for water, and thus plays a drying role. The desiccant itself has stable chemical properties, and will slowly absorb water and release heat when it meets water, and the heating process will not be violent; because the data cable is frozen and will be twisted The data cable may be deformed, and some may even cause the core line to break or increase the loss, resulting in a large signal attenuation, and finally causing transmission interruption or affecting the normal use of the user. Therefore, the mineral desiccant releases heat when it comes into contact with water to heat and insulate the data cable, which can prevent the data cable from freezing when it encounters cold air after being adhered to water stains. The outer wall of the waterproof layer 4 is provided with a plurality of limit rings 402, and the waterproof layer 4 is divided into a plurality of sections by the plurality of limit rings 402. A sealing layer 5 for sealing the filling groove 401 is wound and installed between two adjacent limit rings 402, and the protective jacket 2 is movably installed on the limit ring 402. While the protective jacket 2 is used to safely protect the cable inner core 1, the protective jacket 2 presses and fixes the sealing layer 5 through the positioning pressure block 202.

[0038] In order to fix the protective jacket 2 and ensure the stability of the installation of the protective jacket 2, a sliding groove 4021 is provided on the arc wall surface of the limiting ring 402, and anti-slip ridges 4022 are provided on the left and right sides of the inner wall of the sliding groove 4021. A groove 4023 is provided on the arc wall surface of the limiting ring 402, and the groove 4023 penetrates the limiting ring 402 shell and is connected with the sliding groove 4021; the protective jacket 2 is slidably inserted into the sliding groove 4021 through the limiting slider 201, and the limiting slider 201 is slidably installed in the sliding groove 4021, and the protrusion 2011 is engaged with the anti-slip ridge 4022 to ensure the stability of the protective jacket 2 in the sliding groove 4021; the limiting ring 402 is used to install the protective jacket 2 on the cable core 1, and the protective jacket 2 is used to safely protect the cable core 1.

[0039] In order to protect the cable core 1 and prevent the mineral desiccant filler in the filling groove 401 from leaking, a through hole is opened through the side wall of the protective jacket 2, and a limit slider 201 is fixedly set on the inner wall of the through hole. The protective jacket 2 is installed on the outer wall of the cable core 1, and the cable core 1 is installed in the through hole. The limit slider 201 is adapted to the size of the slot 4023, and a protrusion 2011 is provided on the side wall of the limit slider 201.

The sealing layer 5 can prevent the mineral desiccant filler in the filling groove 401 from leaking, and can prevent the heat generated by the mineral desiccant when it meets water from quickly overflowing, which is beneficial to improving the thermal insulation effect of the data cable.

[0040] In order to prevent the protective jacket 2 from accidentally sliding in the slide groove 4021, the protective jacket 2 is slidably installed in the slide groove 4021 through the limit slider 201, and the protrusion 2011 engages with the anti-slip ridge 4022 to prevent the protective jacket 2 from accidentally sliding in the slide groove 4021, ensuring that the limit slider 201 slides and adjusts its position in the slide groove 4021 only when the protective jacket 2 is rotated and pushed by external force, thereby preventing the limit slider 201 from accidentally sliding out of the slot 4023.

[0041] In order to ensure the safety of the wire core 301 in the core layer, the core layer includes an inner core insulation layer 3, and the side wall of the inner core insulation layer 3 is penetrated with a wire hole, and a plurality of wire cores 301 are installed in the wire hole, and the gaps between the plurality of wire cores 301 are filled with fillers 302, and the wire cores 301 are insulated and protected by the fillers 302; in order to improve the tensile strength of the data cable, the filler 302 is an insulating filler, and a steel wire used as a reinforcing core is inserted and installed in the filler 302, and the tensile strength of the filler 302 is improved by doping the steel wire in the filler 302.

[0042] In order to prevent the heat release of the mineral desiccant from damaging the cable core layer, the protective outer jacket 2 and the inner core insulation layer 3 are both made of PVC material. PVC material has the advantages of high temperature resistance, friction resistance, and strong acid resistance. It is used as insulation and outer protection for data cables and has a stable internal structure. The waterproof layer 4 is made of PTFE material. PTFE material has the advantages of high temperature resistance and heat insulation. It can be used to protect the core layer, prevent the heat energy generated by the mineral desiccant from being transferred to the core layer, and prevent the core layer temperature from being too high.

[0043] Example 2

[0044] In order to prevent the data cable from twisting and deforming when it is damp and frozen, and its circular cross section will be pressed into an irregular shape with uneven bumps, or even cause the core wire to break or increase the loss, the following improvements are made on the basis of Example 1:

[0045] See also Figure 4 As shown, a plurality of filling grooves 401 are provided on the outer wall surface of the waterproof layer 4, a plurality of limit rings 402 are provided on the outer wall of the waterproof layer 4, and the protective jacket 2 is slidably installed in the limit ring 402 through the limit slider 201; when the mineral desiccant does not release heat when in contact with water, the protective jacket 2 and the waterproof layer 4 are damp and frozen, and the outer layers of the protective jacket 2 and the waterproof layer 4 are compressed and deformed. Due to the groove structure on the outer side of the waterproof layer 4 and the gap between the waterproof layer 4 and the protective jacket 2, a certain deformation buffer space can be provided for the waterproof layer 4, thereby reducing the extrusion damage to the core layer; further, when the waterproof layer 4 and the protective jacket 2 are frozen and deformed, causing moisture or water penetration, the mineral desiccant releases heat when in contact with water to heat and insulate the data cable, thereby preventing the data cable from further freezing.
