Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a moisture-proof and environmentally friendly cable. Background Technology

[0002] Cables are typically rope-like wires made of several or more strands of conductors twisted together. Each strand of conductor is insulated from the others and twisted around a central core, with the entire structure covered by a sheath. The conductive cores are usually made of copper or aluminum and are responsible for transmitting current. The outer sealed sheath protects the insulated cores from mechanical damage, moisture, and other hazards. There are many types of cables, including power cables, control cables, and communication cables, which are widely used in power transmission systems, signal transmission systems, and various electrical equipment.

[0003] However, when cables are used in the external environment for a long time and subjected to external forces such as pulling and dragging, external wear and tear will occur. As the usage time increases, the cable core will eventually be exposed, affecting the stability of the cable and posing certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to provide a moisture-proof and environmentally friendly cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof and environmentally friendly cable, comprising a cable body, a wire core fixedly connected to the center inside the cable body, a first inclined groove provided on the outer ring of the left and right sides of the cable body, annular grooves evenly spaced laterally provided on the outside of the cable body, a rubber ring sleeved on the outside of the annular grooves, a second inclined groove provided on the inner ring of the left and right sides of the rubber ring, the second inclined groove being used for guiding the connection between the cable body and the rubber ring, and also including a connecting mechanism for reinforcing the connection between the cable body and the rubber ring, and a material layer provided inside the cable body.

[0006] Preferably, the wire core is made of a composite material of highly conductive copper wire and silver-plated copper wire, and water-absorbing and expanding rubber is filled at the connection of multiple sets of wire cores.

[0007] Preferably, the rubber ring is made of wear-resistant rubber.

[0008] Preferably, the connecting mechanism includes protrusions that are uniformly and circumferentially fixed to the outside of the annular groove, and a filling groove is provided in the center of the inside of the rubber ring. The filling groove is provided with a filler, and the filler is made of polyurethane foam. The protrusions are used to increase the contact area with the filler.

[0009] Preferably, the material layer is provided with a weather-resistant layer, a composite layer, and an insulating layer from the outside to the inside.

[0010] Preferably, the weather-resistant layer is made of environmentally friendly polyvinyl chloride and silicone composite material, the composite layer is made of fluoroplastic and polyethylene composite material, and the insulating layer is made of cross-linked polyethylene material.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This type of moisture-proof and environmentally friendly cable features multiple sets of annular grooves on the outside of the cable body to accommodate rubber rings. These rubber rings prevent direct contact between the cable and the external environment, reducing wear during use. Simultaneously, the rubber rings are filled with filler material. Heating this filler material causes it to expand rapidly, providing stable filling at the connection between the cable body and the rubber rings. This increases the stability of the connection, effectively preventing direct contact between the cable and the external environment while providing effective wear protection and extending the overall service life of the cable.

[0013] 2. This type of moisture-proof and environmentally friendly cable incorporates multiple material layers within its main body, including a weather-resistant layer, a composite layer, and an insulation layer. The outermost weather-resistant layer enhances waterproofing and improves the cable's external high-temperature resistance. The composite layer within the weather-resistant layer provides excellent chemical corrosion resistance and effectively improves the cable's internal abrasion and impact protection. The insulation layer within the composite layer provides insulation protection while offering enhanced stability and voltage resistance. Furthermore, the filler layer connecting the wire cores incorporates water-absorbing and expanding rubber, effectively protecting the cores from moisture. This enhances the overall performance of the cable and ensures its stability in complex environments. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-4 This utility model provides two technical solutions:

[0021] Example 1: A moisture-proof and environmentally friendly cable includes a cable body 1, with a wire core 101 fixedly connected to the center inside the cable body 1. First inclined grooves 102 are provided on the outer ring positions of the left and right sides of the cable body 1. Annular grooves 103 are evenly spaced laterally arranged on the outside of the cable body 1. A rubber ring 2 is fitted onto the outside of the annular grooves 103. Second inclined grooves 201 are provided on the inner ring positions of the left and right sides of the rubber ring 2. The second inclined grooves 201 are used for guiding the connection between the cable body 1 and the rubber ring 2. The cable body 1 also includes a connecting mechanism 3 for reinforcing the connection between the cable body 1 and the rubber ring 2. A material layer 4 is provided inside the cable body 1. The arrangement of the wire core 101 and the second inclined grooves 201 facilitates the quick and easy fitting of the rubber ring 2 onto the outside of the cable body 1.

[0022] The conductor 101 is made of a composite material of highly conductive copper wire and silver-plated copper wire, and water-absorbing and expanding rubber is filled at the connection of multiple conductors 101. The silver-plated copper wire can increase the conductivity of the copper wire and has anti-oxidation properties, which improves the stability of conductor 101 in use. Water-absorbing and expanding rubber is provided at the connection of conductors. When moisture appears around the conductor, it will expand rapidly to form a tight seal, thereby preventing moisture from further penetrating into the inside of the cable.

[0023] The rubber ring 2 is made of wear-resistant rubber material to ensure the protection of the cable body 1 and extend the service life of the rubber ring 2.

[0024] The connecting mechanism 3 includes protrusions 104 that are uniformly and circumferentially fixed to the outside of the annular groove 103. A filling groove 202 is opened in the center of the rubber ring 2. A filler 301 is provided inside the filling groove 202. The filler 301 is made of polyurethane foam. The protrusions 104 are used to increase the contact area with the filler 301. The protrusions 104 can increase the contact area between the cable body 1 and the rubber ring 2 when the filler 301 expands. At the same time, the filler 301 in the connecting mechanism 3 can expand rapidly when heated to complete the filling work inside the rubber ring 2.

[0025] Example 2 differs from Example 1 mainly in that:

[0026] A moisture-proof and environmentally friendly cable, wherein the material layer 4 is provided with a weather-resistant layer 401, a composite layer 402, and an insulation layer 403 from the outside to the inside.

[0027] The weather-resistant layer 401 is made of environmentally friendly polyvinyl chloride and silicone composite material. Environmentally friendly polyvinyl chloride can reduce the release of toxic substances, while silicone is suitable for high-temperature environments and improves the overall waterproof performance of the cable.

[0028] The composite layer 402 is made of fluoroplastic and polyethylene composite material, which has extremely high chemical corrosion resistance and good electrical insulation properties. It is suitable for cable use in harsh environments and has wear resistance and impact resistance.

[0029] The insulation layer 403 is made of cross-linked polyethylene, which has higher thermal stability and stronger voltage resistance than conventional polyethylene materials, providing a more stable voltage resistance effect. Meanwhile, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0030] In this embodiment of the application, the rubber ring 2 is fitted onto the annular groove 103 outside the cable body 1. At this time, by heating the outside of the rubber ring 2, the filler 301 inside the rubber ring 2 can be heated and expanded, and fit into the connection between the cable body 1 and the rubber ring 2. At the same time, multiple sets of protrusions 104 are provided in the annular groove 103 to increase the contact area with the filler 301, and improve the connection effect of the rubber ring 2 outside the cable body 1. At this time, the rubber ring 2 can prevent the cable body 1 from contacting the outside and effectively perform wear-resistant protection of the cable body 1.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
