Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an environmentally friendly cable capable of preventing excessive bending and deformation. Background Art

[0002] Cables are mainly used to transmit and distribute electrical energy. From home to industry, from transportation to communication, they are inseparable from the support of cables. They are widely used in various fields such as power systems, buildings and industrial equipment. Cables will inevitably bend during the laying process. Therefore, the bending resistance of cables is an important indicator to ensure that the cables are not excessively deformed.

[0003] At present, there are two main ways to improve the bending resistance of cables. One way is to use anti-deformation accessories. For example, accessories and connectors with anti-deformation characteristics can be selected, and then the accessories or connectors are fixedly installed on the outside of the cable. This method requires additional accessories and connectors, which brings many inconveniences to the cable laying operation. Another way is to add a reinforcement structure inside the cable. For example, a Chinese patent document with publication number CN118136314A discloses a bending-resistant and low-temperature-resistant cable for drilling equipment. It uses a process of twisting and re-twisting multiple fine conductor bundles, aramide wires are set in the conductors, and the wire cores are twisted in groups. The cable is also twisted in the same direction in each process. The bending resistance of the cable is increased. The aramid wire used in the above patent technology is a synthetic fiber, and the synthetic limit process is relatively complicated and the price is relatively high. At the same time, the cost of implementing the technology of small pitch control of cable cabling and twisting in the same direction in each process is high, which is not conducive to the company's control of production costs. Utility Model Content

[0004] The technical problem to be solved by the utility model is that in the prior art, the processing cost of the anti-bending cable is high. Based on this, the utility model provides an environmentally friendly cable that is anti-excessive bending and deformation and has a low production cost.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an environmentally friendly cable that prevents excessive bending and deformation, including a cable core unit, an anti-bending component is arranged on the outside of the cable core unit, an extruded layer is arranged on the outside of the anti-bending component, a wrapping tape is arranged on the outside of the extruded layer, an environmentally friendly layer is arranged on the outside of the wrapping tape, the anti-bending component includes an anti-bending part and an elastic part, the anti-bending part is made of hard plastic, the anti-bending part has a plurality of anti-bending parts and is arranged at intervals on the outside of the cable core unit along the extension direction of the cable, and one elastic part is arranged between every two adjacent anti-bending parts.

[0006] Furthermore, flanges are formed on the side walls at the opposite ends of the anti-bending member extending radially outwardly along the anti-bending member, and the elastic member is arranged between two flanges close to each other, one end of the elastic member abuts against one of the flanges, and the other end of the elastic member abuts against the other flange.

[0007] Furthermore, the outer diameter of the elastic member is the same as the outer diameter of the flange.

[0008] Furthermore, a plurality of the anti-bending parts are arranged at equal intervals.

[0009] Furthermore, the elastic member is a rubber sleeve.

[0010] Furthermore, the environmental protection layer is made of cross-linked polyethylene material.

[0011] Furthermore, the cable core unit comprises a metal conductor, an insulating layer, a shielding layer and an inner sheath, wherein the insulating layer is arranged outside the metal conductor, the shielding layer is arranged outside the insulating layer, and the inner sheath is arranged outside the shielding layer.

[0012] Furthermore, the shielding layer is made of aluminum foil material or braided copper mesh material.

[0013] The beneficial effects of the utility model are as follows: the environmentally friendly cable of the utility model that prevents excessive bending and deformation, the anti-bending member sleeved on the outside of the cable core unit can enhance the structural strength of the cable core unit on the one hand, and on the other hand, when the cable is bent, the ends of the two anti-bending members close to each other are mutually limited due to their close proximity, thereby limiting the further bending of the cable, effectively avoiding excessive bending and deformation of the cable, and the production cost is low. In addition, the elastic member arranged between two adjacent anti-bending members ensures that the cable can have a certain bending and deformation ability, which is conducive to winding and laying.

DETAILED DESCRIPTION

[0019] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0020] See also Figure 1-Figure 3 The utility model provides an environmentally friendly cable that prevents excessive bending and deformation, including a cable core unit 1, an anti-bending component 2 is arranged on the outside of the cable core unit 1, an extruded layer 3 is arranged on the outside of the anti-bending component 2, a wrapping tape 4 is arranged on the outside of the extruded layer 3, an environmental protection layer 5 is arranged on the outside of the wrapping tape 4, and an outer sheath 6 is arranged on the outside of the environmental protection layer 5.

[0021] The cable core unit 1 includes a metal conductor 11 , an insulating layer 12 , a shielding layer 13 and an inner sheath 14 . The insulating layer 12 is arranged outside the metal conductor 11 , the shielding layer 13 is arranged outside the insulating layer 12 , and the inner sheath 14 is arranged outside the shielding layer 13 .

[0022] In specific implementation, the metal conductor 11 can be selected according to the use environment and requirements of the cable. For example, copper conductors have high conductivity and good mechanical properties, so they can be used for high-voltage cables; aluminum conductors have higher resistivity and lower cost than copper conductors, so they can be used for low-voltage cables. The insulating layer 12 is made of polyvinyl chloride (PVC). The shielding layer 13 is made of aluminum foil or braided copper mesh to isolate electromagnetic interference from electrical appliances or other interference sources.

[0023] The anti-bending component 2 includes an anti-bending member 21 and an elastic member 22. The anti-bending member 21 has multiple anti-bending members and is spaced apart along the extension direction of the cable on the outside of the cable core unit 1. An elastic member 22 is arranged between each two adjacent anti-bending members 21, wherein the anti-bending member 21 is made of hard plastic and the elastic member 22 is made of elastic material. In this embodiment, the anti-bending member 21 is made of PVC material, which is low in price and is conducive to controlling production costs for enterprises. When in use, the anti-bending member 21 is sleeved on the outside of the cable core unit 1. Since the anti-bending member 21 is made of hard material, the structural strength of the part corresponding to the anti-bending member 21 on the cable core unit 1 is relatively large, and it is not easy to bend and deform. The empty part between the two adjacent anti-bending members 21 on the cable core unit 1 is easy to bend, thereby ensuring that the cable has a certain bending ability to meet the needs of winding and laying. The elastic member 22 located between the two adjacent anti-bending members 21 is squeezed when the cable is bent, and then a certain elastic deformation can occur. The elastic force generated by the elastic deformation can increase the difficulty of bending the cable, thereby avoiding excessive bending and deformation of the cable. In this embodiment, the elastic member 22 is a rubber sleeve.

[0024] As a preferred embodiment, the anti-bending member 21 is a cylindrical structure with two ends through, and the side walls at the two opposite ends of the anti-bending member 21 extend radially outward along the anti-bending member 21 to form flanges 211, and the elastic member 22 is arranged between two flanges 211 close to each other, one end of the elastic member 22 abuts against one of the flanges 211, and the other end of the elastic member 22 abuts against the other flange 211. By setting the flange 211, the relative area between the two anti-bending members 21 is increased, and when the cable is bent and deformed, the outermost edges of the two flanges 211 can be closer to each other more easily, thereby helping to limit the cable from continuing to bend and improving the anti-bending ability of the cable. At the same time, the anti-bending member 21 is set to a structure with thick ends and thin middle, which reduces the weight of the anti-bending member 21 while ensuring the structural strength, and facilitates the cable processing personnel to put the anti-bending member 21 on the cable core unit 1.

[0025] Furthermore, the elastic member 22 is a cylindrical structure with two ends penetrated, and the outer diameter of the elastic member 22 is the same as the outer diameter of the flange 211. In addition, the plurality of anti-bending members 21 are arranged at equal intervals.

[0026] The extruded layer 3 is formed by extrusion by an extrusion machine. After the anti-bending parts 21 and the elastic parts 22 are staggered and mounted on the cable core unit 1, the cable core unit 1 can be passed through the extrusion die of the extrusion machine, and the molten plastic is wrapped around the outside of the anti-bending component 2, and then tightly combined with the outside of the anti-bending component 2 after cooling. The operation is simple and convenient, and the production cost is low.

[0027] In this embodiment, the wrapping tape 4 is a mica tape, which has a certain fire-isolating effect and can effectively prevent external flames from quickly igniting other structures inside the mica tape.

[0028] In this embodiment, the environmental protection layer 5 is made of cross-linked polyethylene material. The cross-linked polyethylene material does not produce thick smoke and toxic and harmful gases when burning. It has good environmental protection performance and can provide rescue personnel with sufficient rescue time when the cable burns. It is safe to use.

[0029] The outer sheath 6 is a silicone sheath, which has a certain hardness and can reduce the wear of the cable.

[0030] In the environmentally friendly cable that prevents excessive bending and deformation of the utility model, the anti-bending member 21 sleeved on the outside of the cable core unit 1 can enhance the structural strength of the cable core unit 1 on the one hand, and on the other hand, when the cable is bent, the ends of the two anti-bending members 21 close to each other are mutually limited due to their close proximity, thereby limiting the further bending of the cable, effectively avoiding excessive bending and deformation of the cable, and the production cost is low. In addition, the elastic member 22 arranged between two adjacent anti-bending members 21 ensures that the cable can have a certain bending and deformation ability, which is conducive to winding and laying.

[0031] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
