Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to an insulated cable with a pressure-resistant and water-blocking layer. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors. Cables include power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, and many more. The manufacturing process of cables differs significantly from that of most electromechanical products. Cables are measured in length, and all wires and cables begin with conductor processing, adding layers of insulation, shielding, cabling, and sheathing around the conductor to create the final product. The more complex the product structure, the more layers are added. According to announcement number CN214099221U, an elliptical pressure-resistant waterproof and moisture-proof wire and cable is disclosed. This technology discloses "an outer layer, in which a metal braided mesh is fixedly sleeved on the inner wall of the outer layer, a sheath layer is fixedly sleeved on the inner wall of the metal braided mesh, a moisture-proof layer is fixedly sleeved on the inner wall of the sheath layer, a water-blocking layer is fixedly connected to the inner wall of the moisture-proof layer, and a pressure-resistant structural layer is fixedly sleeved on the inner wall of the water-blocking layer. This utility model, by setting up a first pressure-resistant layer, a second pressure-resistant layer, a buffer layer, etc., the first pressure-resistant layer and the second pressure-resistant layer are fixedly connected to the buffer layer by insulating adhesive, ensuring the overall insulation of the pressure-resistant structural layer. Moreover, the buffer layer itself is made of rubber, and rubber has a certain degree of elasticity. When the cable is subjected to external pressure, the elastic deformation of the buffer layer can buffer the pressure. Furthermore, the first pressure-resistant layer and the second pressure-resistant layer work together to protect the inner core of the cable, greatly improving the pressure resistance of the cable." Although this design ensures the overall insulation of the pressure-resistant structural layer, and the buffer layer itself is made of rubber, which has a certain degree of elasticity, allowing the cable to be subjected to external pressure through the elastic deformation of the buffer layer to buffer the pressure, and the first and second pressure-resistant layers work together to protect the inner core of the cable, greatly improving the cable's pressure resistance, the overall structure of the device is elliptical, and its pressure resistance relies entirely on the material itself. Therefore, under long-term use and pressure resistance, the material may age rapidly, thus affecting normal operation.

[0003] To address the aforementioned problems, this application proposes an insulated cable with a pressure-resistant and water-blocking layer. Utility Model Content

[0004] To address the problems mentioned in the background section, this invention provides an insulated cable with a pressure-resistant and water-blocking layer. The pressure-resistant tape allows for expansion and compression on its surface when the outer protective sheath is compressed, thereby absorbing and releasing stress, unlike a straight metal tape which directly bears enormous tensile and compressive stress. This allows it to be used in harsh environments and dynamic applications where reliability, durability, and performance stability are extremely important. Furthermore, the outer and inner water-blocking pastes have high viscosity, effectively increasing the resistance to water penetration and slowing its spread, thus achieving excellent water-blocking performance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulated cable with a pressure-resistant and water-blocking layer, comprising an outer protective sheath, and an outer water-blocking paste disposed inside the outer protective sheath. One side of the outer water-blocking paste is provided with a pressure-resistant band, and the other side of the pressure-resistant band is provided with an inner water-blocking paste. One side of the inner water-blocking paste is provided with an armor, and the other side of the armor is provided with a foam filling layer. The side of the foam filling layer away from the armor is provided with a conductor core.

[0006] As a preferred embodiment of the present invention, an insulated cable with a pressure-resistant and water-blocking layer is provided, wherein the outer protective sleeve is fitted over the outside of the pressure-resistant band, and the pressure-resistant band is connected to the outside of the armor, with both sides of the pressure-resistant band.

[0007] As a preferred embodiment of the insulated cable with a pressure-resistant and water-blocking layer according to this utility model, the pressure-resistant strip has a continuous wavy structure and is spirally wound around the outside of the armor. The material of the pressure-resistant strip is a high-toughness metal.

[0008] As a preferred embodiment of the insulating cable with a pressure-resistant and water-blocking layer according to this utility model, the inner water-blocking paste and the outer water-blocking paste are semi-solid paste materials.

[0009] As a preferred embodiment of the insulated cable with a pressure-resistant and water-blocking layer according to this utility model, one side of the armor is also connected to the surface of the isolation sleeve, and the inner surface of the isolation sleeve is fixedly connected to the surface of the wrapping tape.

[0010] As a preferred embodiment of the present invention, an insulated cable with a pressure-resistant and water-blocking layer is provided, wherein one side of the wrapping tape is fixedly connected to the foam filling layer, and the interior of the foam filling layer is filled with a copper tape shielding layer, an insulating shielding layer, XLPE insulation, a conductor shielding layer and a conductor core, and the copper tape shielding layer, the insulating shielding layer, the XLPE insulation, the conductor shielding layer and the conductor core are distributed at equal angles in a nested structure inside the foam filling layer.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the pressure-resistant tape can expand and compress when the outer protective sleeve is compressed, thereby absorbing and releasing stress, instead of directly bearing huge tensile and compressive stress like a straight metal tape. It can be used in harsh environments and dynamic applications with extremely high requirements for reliability, durability and performance stability. The outer and inner water-blocking pastes have high viscosity, which can effectively increase the resistance to water penetration and slow down its spread, thus achieving a good water-blocking effect.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0014] like Figure 1 As shown: An insulated cable with a pressure-resistant and water-blocking layer includes an outer protective sheath 1.

[0015] In this implementation plan: The existing announcement number CN214099221U discloses an elliptical pressure-resistant waterproof and moisture-proof wire and cable. The technical means of this will not be described in detail here. For details on the improvement of this prior art, please refer to the following disclosure. In order to solve the technical problems existing in this prior art, such as the "the overall structure of the device is elliptical, and its pressure resistance relies entirely on the material itself. Therefore, under long-term use and pressure resistance, the material may age rapidly, which will affect normal use." In terms of use, this problem is obviously a real and difficult problem to solve. In view of this, in order to solve the above problems, an external water-blocking paste 2 and a pressure-resistant strip 3 are added on the basis.

[0016] Furthermore: like Figure 1 - Figure 5 As shown: In conjunction with the above, it also includes an external water-blocking paste 2 inside the outer protective sleeve 1, an anti-pressure band 3 on one side of the external water-blocking paste 2, an internal water-blocking paste 4 on the other side of the anti-pressure band 3, an armor 5 on one side of the internal water-blocking paste 4, a foam filling layer 8 on the other side of the armor 5, and a conductor core 13 on the side of the foam filling layer 8 away from the armor 5.

[0017] In this implementation scheme: Under the action of the compression-resistant belt 3, when the outer protective sleeve 1 is compressed, the surface of the compression-resistant belt 3 can be stretched and squeezed, thereby absorbing and releasing stress, instead of directly bearing huge tensile and compressive stress like a straight metal belt. It can be used in harsh environments and dynamic applications with extremely high requirements for reliability, durability and performance stability.

[0018] Furthermore: In an optional embodiment, the outer protective sleeve 1 is fitted over the outside of the pressure-resistant band 3, and the pressure-resistant band 3 is connected to the outside of the armor 5, on both sides of the pressure-resistant band 3.

[0019] In this embodiment, the outer protective sleeve 1 can prevent the pressure-resistant band 3 from being corroded, enabling it to perform a long-term and stable buffering and pressure-resistant function, thus providing a stable working space and conditions for the cable.

[0020] Furthermore: In an optional embodiment, the pressure-resistant band 3 has a continuous wavy structure and is spirally wound around the outside of the armor 5. The pressure-resistant band 3 is made of a high-toughness metal.

[0021] In this embodiment: Under the action of the compression-resistant band 3, the deformation generated by the compression-resistant band 3 can be used for buffering, avoiding damage to the internal structure of the compression-resistant band 3, and providing a guarantee for the normal use of the cable.

[0022] Furthermore: In an optional embodiment, the inner water-blocking paste 4 and the outer water-blocking paste 2 are semi-solid paste materials.

[0023] In this embodiment, the outer water-blocking paste 2 and the inner water-blocking paste 4 are made of water-blocking paste to avoid the effects of moisture, water vapor, corrosion, etc., and reduce the possibility of optical cable performance degradation or damage.

[0024] Furthermore: In an optional embodiment, one side of the armor 5 is also connected to the surface of the isolation sleeve 6, and the inner surface of the isolation sleeve 6 is fixedly connected to the surface of the strap 7.

[0025] In this embodiment: Under the action of the isolation sleeve 6 and the strap 7, a sealed space can be formed inside the armor 5, thereby preventing the outer water-blocking paste 2 and the inner water-blocking paste 4 from entering the interior of the armor 5, so that the outer water-blocking paste 2 and the inner water-blocking paste 4 can perform normal waterproofing.

[0026] Furthermore: In an optional embodiment, one side of the wrapping tape 7 is fixedly connected to the foam filling layer 8, and the interior of the foam filling layer 8 is filled with a copper tape shielding layer 9, an insulating shielding layer 10, an XLPE insulation layer 11, a conductor shielding layer 12, and a conductor core 13. The copper tape shielding layer 9, the insulating shielding layer 10, the XLPE insulation layer 11, the conductor shielding layer 12, and the conductor core 13 are distributed at equal angles in a nested structure inside the foam filling layer 8.

[0027] In this embodiment, the copper strip shielding layer 9, the insulating shielding layer 10, the XLPE insulation 11, the conductor shielding layer 12, and the conductor core 13 arranged in a nested structure can provide a stable protective structure for the foam filling layer 8 during use, and can also achieve stable power supply operation.

[0028] The working principle and usage process of this utility model are as follows: When laying the outer protective sleeve 1, the laying work can be carried out according to the normal process. When the outer protective sleeve 1 is subjected to external pressure, the pressure-resistant band 3 set inside it can deform when it feels the pressure generated by the outer protective sleeve 1 and buffer the impact force to avoid affecting other internal structures. The wave-shaped pressure-resistant band 3 can stably wrap between the armor 5 and the outer protective sleeve 1 to provide stable buffering and pressure resistance. At the same time, the outer water-blocking paste 2 and the inner water-blocking paste 4 can play a good waterproofing role when the outer protective sleeve 1 is damaged, preventing water from entering the location of the conductor core 13 and affecting the power supply.

[0029] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
