Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric wires, in particular to a flexible waterproof electric wire. Background Art
[0002] Although traditional wire products have good electrical properties, they often lack waterproof performance and mechanical strength. Especially in some harsh environments, such as underwater, humid areas, or occasions where bending is often required, traditional wires are prone to failure, resulting in power supply interruptions and even safety accidents. Although some waterproof wires on the market currently have certain waterproof properties, they are often not flexible enough and difficult to adapt to complex and changeable installation conditions. In addition, the waterproof performance is easily reduced due to wear during long-term use.
[0003] In addition, existing waterproof wires usually rely on a single waterproof layer and lack a multi-layer waterproof mechanism, which means that once one layer is damaged, the waterproof performance of the entire wire will be greatly reduced. Therefore, developing a wire with excellent waterproof performance and high mechanical strength and flexibility has become a technical problem that needs to be solved urgently. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a flexible waterproof wire to solve the problems in the background technology.
[0005] In view of this, the utility model provides a flexible waterproof electric wire, comprising a copper core;
[0006] A silicone sheath is provided on the outer side of the copper core;
[0007] A water-blocking tape is wound around the outside of the silicone sheath;
[0008] A strength reinforcement layer is provided on the outer side of the water blocking tape, and the strength reinforcement layer is composed of an armor layer woven from steel wires;
[0009] A polyurethane sheath is provided on the outer side of the strength reinforcement layer;
[0010] A water-blocking powder filling layer is filled between the strength reinforcement layer and the outer polyurethane sheath.
[0011] Optionally, the copper core is formed by twisting a plurality of copper wires with a diameter of 0.5 mm.
[0012] Optionally, the thickness of the silicone sheath is 0.3mm-0.5mm.
[0013] Optionally, the strength reinforcement layer is an armor layer woven from steel wires.
[0014] Optionally, a self-healing material layer is provided on the outer side of the polyurethane sheath, and the self-healing material layer is made of a hydrogel material.
[0015] Optionally, the water-blocking tape is made of a water-swellable material, which can expand when moisture penetrates to prevent further moisture from entering the interior of the wire.
[0016] Optionally, the water-blocking powder filling layer is made of a powder material with high water absorbency and expansibility, which is used to quickly absorb moisture and prevent its continuous diffusion when moisture penetrates.
[0017] It can be seen from the above technical solutions that the embodiments of the present utility model have the following advantages:
[0018] 1. For a flexible waterproof wire of the present utility model, by providing multiple waterproof layers such as a silicone sheath, a water-blocking tape, and a water-blocking powder filling layer, the present utility model can effectively prevent moisture from penetrating into the interior of the wire, thus significantly improving the waterproof performance of the wire. At the same time, the armor layer woven by steel wires is used as the strength reinforcement layer, which not only enhances the overall mechanical strength of the wire but also ensures that the wire can still maintain its structural integrity when subjected to external pressure or tension, improving the durability of the wire.
[0019] 2. For a flexible waterproof wire of the present utility model, the self-healing material layer provided on the outer side of the polyurethane sheath can automatically repair when there are minor damages on the wire surface, improving the reliability and service life of the wire. At the same time, the copper core composed of multiple copper wires with a diameter of 0.5 mm and the outer silicone sheath endow the wire with good flexibility.

[0025] The technical solutions of the embodiments of the present utility model will be explained and described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.
[0026] The following specifically describes a flexible waterproof wire according to an embodiment of the present utility model with reference to the accompanying drawings.
[0027] Embodiment
[0028] For ease of understanding, please refer to Figures 1 to 2 , an embodiment of a flexible waterproof wire provided by the present utility model, including a copper core 1;
[0029] A silica gel sheath 2 is provided outside the copper core 1; the thickness of the silica gel sheath 2 is 0.3 mm to 0.5 mm;
[0030] A water-blocking tape 3 is wound outside the silica gel sheath 2;
[0031] A strength reinforcement layer 4 is provided outside the water-blocking tape 3, and the strength reinforcement layer 4 is composed of an armored layer woven by steel wires;
[0032] A polyurethane sheath 6 is provided outside the strength reinforcement layer 4;
[0033] A water-blocking powder filling layer 5 is filled between the strength reinforcement layer 4 and the outer polyurethane sheath 6.
[0034] It should be noted that outside the silica gel sheath 2, a water-blocking tape 3 made of a water-absorbing and swelling material is wound. The water-blocking tape is relatively soft in the dry state and will quickly expand when it comes into contact with water, forming a physical barrier to effectively prevent water from further penetrating into the wire interior. A water-blocking powder filling layer 5 is filled between the strength reinforcement layer 4 and the outermost polyurethane sheath 6. This layer uses a powder material with high water absorption and expansibility, such as superabsorbent resin SAP. This layer of powder can quickly absorb water and expand when water penetrates, thereby further preventing water from diffusing into the wire interior. Finally, a polyurethane sheath 6 is coated outside all the above layers. The polyurethane sheath 6 can not only provide additional waterproof performance but also has excellent abrasion resistance and chemical corrosion resistance, protecting the wire from the external environment.
[0035] In some embodiments, the copper core 1 is formed by stranding a plurality of copper wires with a diameter of 0.5 mm.
[0036] It should be noted that the copper core 1 in this embodiment is made of multiple copper wires with a diameter of 0.5 mm through a stranding process. These copper wires are annealed to improve their flexibility and electrical conductivity, and to ensure their good bending performance to adapt to various complex installation environments.
[0037] In some embodiments, the thickness of the silica gel sheath 2 is 0.3 mm - 0.5 mm.
[0038] It should be noted that a silica gel sheath 2 with a thickness of 0.3 mm to 0.5 mm is coated on the outside of the copper core 1. The silica gel sheath 2 can be directly coated on the copper core 1 by an extrusion molding method to provide basic insulation and preliminary waterproof protection. Silica gel is selected because of its excellent weather resistance, temperature resistance and flexibility.
[0039] In some embodiments, the strength reinforcement layer 4 is made of steel wires braided into an armor layer.
[0040] It should be noted that an armor layer woven from steel wires is provided outside the water-blocking tape 3 as the strength reinforcement layer 4, which increases the overall mechanical strength and tensile strength of the wire.
[0041] A self-healing material layer 7 is provided on the outside of the polyurethane sheath 6, and the self-healing material layer 7 is made of a hydrogel material.
[0042] It should be noted that a self-healing material layer 7 is added outside the polyurethane sheath 6. This layer is made of a hydrogel material. When small cracks or damages appear on the surface of the wire, the hydrogel material can flow and fill the cracks to achieve self-repair.
[0043] Working principle: The copper core 1, as the main current-carrying part of the wire, is responsible for transmitting current. The copper core 1 made of multiple strands of copper wires with a diameter of 0.5 mm through a stranding process provides high flexibility and electrical conductivity, suitable for occasions that require frequent bending. The silicone sheath 2 provides basic insulation and preliminary waterproof protection. Silicone is selected as the sheath material due to its excellent weather resistance, temperature resistance, and flexibility. The silicone sheath 2 with a thickness of 0.3 mm to 0.5 mm can effectively isolate the copper core 1 from the external environment, preventing short circuits or electric shock accidents. The water-blocking tape 3 prevents moisture from entering the wire interior. The water-blocking tape is made of a water-absorbing and swelling material, which will rapidly expand when in contact with moisture, forming a physical barrier to prevent further penetration of moisture into the wire interior. The strength reinforcement layer 4 enhances the overall mechanical strength of the wire. The water-blocking powder filling layer 5 further prevents the diffusion of moisture. The water-blocking powder filling layer 5 uses a powder material with high water absorption and expansibility, such as superabsorbent resin SAP. When moisture penetrates, these powders rapidly absorb the moisture and expand, thus preventing the moisture from continuing to diffuse into the wire interior. The polyurethane sheath 6 provides additional waterproof performance and protection. The self-healing material layer 7 improves the durability and self-repair ability of the wire. The self-healing material layer 7 made of a hydrogel material can flow and fill the cracks when small cracks or damages appear on the wire surface, achieving self-repair, thereby improving the reliability and safety of the wire.
[0044] As described above, the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present application.
