Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a polypropylene wear-resistant and waterproof electric wire and cable. Background Art

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and electromagnetic energy conversion. In a broad sense, wires and cables are also simply called cables. In a narrower sense, cables refer to insulated cables, which can be defined as a collection of the following components: one or more insulated wire cores, each of which may have a sheath, a protective layer, and an outer sheath. Cables may also have additional uninsulated conductors. They are wire products used to transmit electrical (magnetic) energy, information, and electromagnetic energy conversion. Existing wire and cable structures have poor wear resistance and, after prolonged use, lack ideal waterproofing, making them difficult to meet the demands of long-term use.

[0003] A search revealed patent publication number CN201720457360.3, which discloses a wear-resistant and waterproof wire and cable. While this device boasts high heat resistance through the use of an inner and outer polyvinyl chloride sheath, and a polyurethane layer on the outside of the outer sheath, the cable exhibits excellent oil resistance, toughness, wear resistance, and a long service life. Furthermore, a first waterproof layer is provided inside the outer sheath, and a second waterproof layer is provided inside the core sheath, providing a dual waterproof effect. However, when the device is used, the cable is laid directly on the ground, subjecting it to prolonged frictional contact with the ground. Even if the cable itself is designed with a wear-resistant polyurethane layer, this constant physical friction can still cause wear on the cable sheath, thereby affecting its waterproof and wear-resistant properties. The cable's waterproof performance relies on the first waterproof layer inside the outer sheath and the second waterproof layer inside the core sheath. However, when ground friction causes wear on the outer sheath, the first waterproof layer may be directly exposed to the external environment, increasing the risk of damage. Once the waterproof layer is damaged, the cable's waterproof performance is significantly reduced. Different ground conditions (such as humidity, dust, and oil) can adversely affect cable performance. For example, a damp ground can accelerate the aging of the cable sheath, while oil can penetrate into the cable, affecting its electrical performance and safety. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a polypropylene wear-resistant and waterproof wire and cable, which solves the problems raised in the background technology.

[0005] The utility model solves the above-mentioned technical problems as follows:

[0006] A polypropylene wear-resistant and waterproof wire and cable comprises a core wire and a support frame, wherein the core wire is embedded in the support frame, the outer sides of the core wire and the support frame are covered with a shielding layer, and the outer side of the shielding layer is covered with an outer insulating layer;

[0007] The inner side of the shielding layer on the core wire and the support frame is covered with an inner insulating layer, a tensile rope is passed through the gap between the inner insulating layer and the core wire and the support frame, and a support sleeve is sleeved on the outer insulating layer.

[0008] On the basis of the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a positioning groove is provided on the support frame, and the core wire is embedded in the support frame through the positioning groove.

[0010] The beneficial effects of adopting the above further scheme are:

[0011] The positioning groove design allows the core wires to be precisely fixed to the support frame, preventing them from moving or misaligning within the cable, thereby enhancing the overall structural stability of the cable. By embedding the core wires in the support frame through the positioning groove, the relative position of the core wires is ensured to be stable, reducing signal interference caused by core wire movement, thereby improving signal transmission quality. The introduction of the positioning groove simplifies the cable manufacturing process, making the installation and fixing of the core wires more convenient and faster, thereby improving production efficiency.

[0012] Furthermore, a slot is provided on the outer side of the outer insulating layer, and the support sleeve is limitedly sleeved on the outer insulating layer through the slot.

[0013] The beneficial effects of adopting the above further scheme are:

[0014] The combination of the slot and the support sleeve provides a secure connection. This design ensures that the support sleeve fits tightly against the outer insulation layer, preventing it from falling off or loosening, thereby enhancing the overall structural stability of the cable. The slot-type retaining sleeve makes installation of the support sleeve even more convenient. Compared with traditional fixing methods, this design simplifies the assembly process, improves production efficiency, and reduces assembly difficulty. The slot design allows the position and number of support sleeves to be adjusted according to actual needs, providing flexible adaptability. This flexibility allows the cable to adapt to different application scenarios and installation requirements.

[0015] Furthermore, the outer surface of the support sleeve is provided with a support wing plate, and the outer insulation layer is supported away from the ground by the support wing plate of the support sleeve.

[0016] The beneficial effects of adopting the above further scheme are:

[0017] The support wing design allows the cable to maintain a certain distance from the ground, preventing moisture from direct contact with the ground. The support wing also reduces direct contact between the cable and the ground or other objects, thereby reducing wear and tear on the cable. This design helps extend the cable's lifespan and reduces replacement and repair costs due to wear. The support wing design allows the cable to better adapt to various complex environments. Whether on flat ground, rugged mountain roads, or other challenging terrain, the support wing provides stable support for the cable, ensuring its proper operation.

[0018] Furthermore, the slots are evenly distributed on the outer insulating layer, and the support sleeves are evenly distributed on the outer side of the outer insulating layer through the slots.

[0019] The beneficial effects of adopting the above further scheme are:

[0020] The even distribution of the slots and support sleeves on the outer insulation layer ensures balanced support and protection for the cable. This design prevents deformation or damage to the cable due to uneven force, thereby improving its durability and reliability. The evenly distributed support sleeves provide more stable support for the cable, especially under external forces such as wind and human trampling. This reduces cable movement and displacement, ensuring stability and safety. The even distribution of the support sleeves also aids in heat dissipation from the cable. The gaps between the support sleeves act as heat dissipation channels, helping to dissipate heat within the cable, reducing cable temperature and extending its service life.

[0021] Furthermore, two tension ropes are provided on both sides of each core wire. The core wire is protected from tension by the tension ropes and is fixed by the inner insulating layer, the support frame and the tension ropes.

[0022] The beneficial effects of adopting the above further scheme are:

[0023] Two tension cords are placed on either side of each core, significantly enhancing the cable's tensile strength. When the cable is stretched, the tension cords effectively distribute and absorb the force, preventing breakage or damage to the cores due to excessive tension. The tension cords not only provide tensile protection but also enhance the cable's overall stability by compressing and securing the inner insulation layer, support frame, and tension cords. This design ensures that the cable maintains its structural integrity and stability when subjected to external forces, preventing deformation or displacement.

[0024] The utility model provides a polypropylene wear-resistant and waterproof wire and cable. It has the following beneficial effects:

[0025] The core wires and support frame are covered with a shielding layer, which effectively blocks external electromagnetic interference and protects the signal transmission within the cable from external influences. The shielding layer is then covered with an outer insulation layer, further enhancing the cable's protection performance, preventing current leakage and direct physical damage to the cable from the outside.

[0026] The cores and support frame are covered with an inner insulation layer inside the shielding layer. This not only provides additional electrical isolation, but also effectively compresses and secures the cores through the combination of the inner insulation layer, support frame, and tension cords. Two tension cords are located on either side of each core, greatly enhancing the cable's tensile strength and making it less susceptible to breakage under tension.

[0027] A support sleeve is located outside the outer insulation layer, and its outer surface is equipped with support wings. This keeps the cable away from the ground, preventing wear and moisture from direct contact with the ground. The support wings also increase the gap between the cable and the ground, facilitating ventilation and heat dissipation, further extending the cable's service life.

[0028] The slots are evenly distributed on the outer insulation layer, and the support sleeve is fixed to the outer insulation layer via the slot limiter. This design ensures that the support sleeve can be stably fixed to the cable and is not easy to fall off. At the same time, the combination of the slots and the support sleeve also simplifies the cable installation process and improves installation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figures 1 to 3 As shown, the embodiment provided by the utility model:

[0038] Example 1

[0039] A polypropylene wear-resistant and waterproof wire and cable comprises a core wire 3 and a support frame 4. A positioning groove 401 is provided on the support frame 4. The core wire 3 is embedded in the support frame 4 through the positioning groove 401. The precise design of the positioning groove 401 enables the core wire 3 to be accurately positioned and fixed on the support frame 4, effectively avoiding the displacement or misalignment of the core wire 3 inside the cable, thereby significantly improving the overall structural stability of the cable. The core wire 3 is embedded in the support frame 4 using the positioning groove 401, ensuring the constancy of the relative position between the core wires 3, greatly reducing the signal interference caused by the movement of the core wire 3, and thus optimizing the signal transmission quality. In addition, the introduction of the positioning groove 401 simplifies the cable manufacturing process, making the installation and fixing operations of the core wire 3 simpler and faster, and effectively improving production efficiency. The outer sides of the core wire 3 and the support frame 4 are covered with a shielding layer 1, and the outer side of the shielding layer 1 is covered with an outer insulating layer 6.

[0040] Example 2

[0041] In order to support the cable away from the ground and avoid potential damage to the cable caused by moisture or water on the ground, for example, Figures 1 to 3As shown, the utility model also includes: the inner side of the shielding layer 1 on the core wire 3 and the support frame 4 is covered with an inner insulating layer 2, and a tensile rope 5 is inserted into the gap between the inner insulating layer 2 and the core wire 3 and the support frame 4. Two tensile ropes 5 are respectively provided on both sides of each core wire 3. While the core wire 3 is protected from tension by the tensile rope 5, it is also pressed and fixed by the inner insulating layer 2, the support frame 4 and the tensile rope 5. The design of providing two tensile ropes 5 on both sides of each core wire 3 significantly enhances the tensile performance of the cable. When the cable is stretched by external force, the tensile rope 5 can effectively disperse and withstand the tensile force, preventing the core wire 3 from breaking or being damaged due to excessive tension. At the same time, the tensile rope 5 not only provides tensile protection, but also further enhances the overall stability of the cable through the pressing and fixing effect of the inner insulating layer 2, the support frame 4 and the tensile rope 5. This design allows the cable to maintain its structural integrity and stability when subjected to external forces, effectively preventing deformation or displacement. A support sleeve 7 is sleeved over the outer insulating layer 6, and support wings 701 are provided on the outer surface of the support sleeve 7. The outer insulating layer 6 is supported away from the ground by the support wings 701 of the support sleeve 7, protecting the cable from moisture and wear. The design of the support wings 701 maintains a certain distance between the cable and the ground, effectively preventing moisture problems that may arise from direct contact with the ground. Furthermore, the support wings 701 reduce the area of ​​direct contact between the cable and the ground or other objects, reducing the degree of wear caused by friction, helping to extend the cable's service life and reduce replacement and repair costs due to wear. In addition, the design of the support wing plate 701 enables the cable to better adapt to complex and changing external environments. Whether on flat ground, rugged mountain roads, or other special terrains, the support wing plate 701 can provide stable support for the cable to ensure its normal operation. A card slot 601 is provided on the outside of the outer insulating layer 6. The support sleeve 7 is positioned on the outer insulating layer 6 through the card slot 601. The close fit between the card slot 601 and the support sleeve 7 provides a reliable connection method, ensuring that the support sleeve 7 can be firmly attached to the surface of the outer insulating layer 6, avoiding the occurrence of falling off or loosening, thereby enhancing the overall structural stability of the cable. By limiting the card slot 601, the installation process of the support sleeve 7 is simplified, significantly improving assembly efficiency and reducing assembly difficulty compared to traditional fixing methods. The flexible design of the card slot 601 allows the position and number of the support sleeve 7 to be adjusted according to actual needs, thereby providing excellent adaptability and enabling the cable to adapt to diverse application scenarios and installation requirements. The card slots 601 are evenly distributed on the outer insulating layer 6, and the support sleeve 7 is evenly distributed on the outside of the outer insulating layer 6 through the card slots 601. The uniform distribution of the card slots 601 and the support sleeve 7 on the outer insulating layer 6 ensures that the cable is evenly supported and protected, effectively preventing deformation or damage caused by uneven force, thereby improving the durability and reliability of the cable.The evenly distributed support sleeves 7 provide a more stable support for the cable, significantly reducing cable sway and displacement under external forces such as wind and human trampling, ensuring cable stability and safety. Furthermore, the even distribution of the support sleeves 7 helps optimize the cable's heat dissipation performance. The gaps between the support sleeves 7 act as heat dissipation channels, effectively dissipating internal heat from the cable, reducing cable temperature and extending its service life.

[0042] Working principle:

[0043] The core wire 3 is embedded in the positioning groove 401 on the support frame 4. This design ensures the stability and position accuracy of the core wire 3. The support frame 4 provides additional support for the core wire 3, thereby enhancing the overall structural strength of the cable.

[0044] The outer sides of the core wire 3 and support frame 4 are first covered by the inner insulation layer 2, which provides preliminary electrical insulation and mechanical protection. Then, the shielding layer 1 is covered on the outer side of the inner insulation layer 2 to reduce electromagnetic interference and signal loss, ensuring the transmission performance of the cable.

[0045] Tension cords 5 are threaded through the gaps between the inner insulation layer 2, the core wires 3, and the support frame 4. This increases the cable's tensile strength, preventing breakage or damage when subjected to external forces. Two tension cords 5 are placed on either side of each core wire 3, further enhancing the cable's tensile strength and ensuring the stable positioning of the core wires 3.

[0046] The outer insulating layer 6 provides additional electrical insulation and mechanical protection for the cable, while also enhancing its wear resistance. The support sleeve 7 is positioned over the outer insulating layer 6 via retaining grooves 601. Support wings 701 on its outer surface keep the cable away from the ground, preventing moisture and wear from direct contact with the ground. The grooves 601 are evenly distributed across the outer insulating layer 6, ensuring that the support sleeve 7 is also evenly distributed outside the outer insulating layer 6, further enhancing the overall stability and durability of the cable.

[0047] Through the above structural design and material selection, this polypropylene wear-resistant and waterproof wire and cable can maintain stable performance in various harsh environments. It has excellent electrical insulation performance, tensile strength, wear resistance and waterproof performance, and can meet the use requirements of various complex environments.
