Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electrical equipment technology, specifically referring to a bending-resistant electrical wire. Background Technology
[0002] Electric wires are conductors used to transmit electrical energy. Electric wires are classified into bare wires, magnet wires, and insulated wires. They are mainly used in outdoor overhead lines and indoor busbars and switch boxes. Power wires are commonly used in urban underground power grids, power plant lead-out lines, internal power supply in industrial and mining enterprises, and underwater transmission lines across rivers and seas. The proportion of electric wires in power lines is gradually increasing. Power wires are electrical products used in the main lines of power systems to transmit and distribute high-power electrical energy, including various voltage levels from 1-500KV and above, and various types of insulated power wires.
[0003] However, bending of existing wires during use can cause metal fatigue and breakage of the wire core, while cracks may also appear in the outer insulation, leading to the risk of leakage. Utility Model Content
[0004] In view of the above situation and to overcome the defects of the prior art, this utility model proposes an anti-bending wire, which effectively solves the problem that bending of the wire during use will cause metal fatigue and breakage of the wire core, and at the same time, cracks will appear in the outer insulation protection, resulting in the risk of leakage.
[0005] The technical solution adopted by this utility model is as follows: This utility model proposes an anti-bending wire, including an anti-aging and wear-resistant coating, an anti-bending structure, and a conductive wire structure. The anti-bending structure is disposed within the anti-aging and wear-resistant coating, and the conductive wire structure is disposed within the anti-aging and wear-resistant coating. The anti-bending structure includes an insulating sheath, an anti-bending spring, a winding layer, anti-bending ribs, and an insulating layer. The insulating sheath is disposed within the anti-aging and wear-resistant coating. The anti-bending spring is bolted through the insulating sheath. The winding layer is rotatably wound on the inner wall of the insulating sheath. The anti-bending ribs are arranged on the inner wall of the winding layer, and the insulating layer is disposed inside the anti-bending ribs.
[0006] Preferably, the conductive wire structure includes a shielding layer and a conductor, wherein the shielding layer is disposed inside the insulating layer and the conductor is disposed inside the shielding layer.
[0007] To better achieve the effect of resisting bending, the anti-bending ribs are made of glass fiber material, and the winding layer is made of Oxford cloth material.
[0008] To achieve bending resistance more quickly, several sets of bending-resistant ribs are arranged around the perimeter.
[0009] Furthermore, the anti-bending spring is made of elastic memory metal and is arranged in a helical shape.
[0010] To achieve the effect of conductivity and breakage prevention, the conductor is made of copper, aluminum and steel wires wound together.
[0011] The beneficial effects of this utility model using the above structure are as follows: The anti-bending wire proposed in this solution has an anti-bending spring inside the insulation sheath to prevent breakage when bent, and an internal spiral winding anti-bending rib to increase toughness and prevent bending. At the same time, the conductor is set in a fine filament rotating arrangement so that it will not break when bent. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0019] like Figure 1 , Figure 3 and Figure 4As shown, the present invention proposes an anti-bending wire, comprising an anti-aging and wear-resistant coating 1, an anti-bending structure 2, and a conductive wire structure 3. The anti-bending structure 2 is disposed within the anti-aging and wear-resistant coating 1, and the conductive wire structure 3 is disposed within the anti-aging and wear-resistant coating 1. The anti-bending structure 2 includes an insulating sheath 4, an anti-bending spring 5, a winding layer 6, anti-bending ribs 7, and an insulating layer 8. The insulating sheath 4 is disposed within the anti-aging and wear-resistant coating 1. The anti-bending spring 5 is bolted through the insulating sheath 4 and is made of elastic memory metal and is arranged in a spiral shape. The winding layer 6 is rotated and wound on the inner wall of the insulating sheath 4 and is made of Oxford cloth. The anti-bending ribs 7 are arranged on the inner wall of the winding layer 6 and are made of glass fiber material. Several groups of anti-bending ribs 7 are arranged around one circumference. The insulating layer 8 is disposed inside the anti-bending ribs 7.
[0020] like Figure 2 , Figure 3 and Figure 4 As shown, the conductive wire structure 3 includes a shielding layer 9 and a conductor 10. The shielding layer 9 is disposed inside the insulating layer 8, and the conductor 10 is disposed inside the shielding layer 9. The conductor 10 is made of copper, aluminum and steel wires wound together.
[0021] In practical use, when a bend occurs, the inner winding layer 6 of the anti-bending spring 5 quickly returns to its original shape after bending, preventing the anti-bending spring 5 from breaking. At the same time, the winding layer 6 is elastic, and the anti-bending rib 7 has a high rebound strength when bent, providing good anti-bending performance. Meanwhile, the winding of the conductor 10 causes it to be stretched when bent, preventing rigid bending and breakage. The above describes the performance characteristics of the anti-bending wire.
