Description

Technical Field

[0001] The utility model relates to the technical field of electric wires, and in particular to an anti-scratch electric wire. Background Art

[0002] The existing wire structure is relatively common, such as the patent number 201721489951.5, which is an electric vehicle wire with good anti-scratch effect. For details, please refer to Figure 1 ,like Figure 1 As shown, the electric wire includes an insulating layer body 1, an energized wire 2 is arranged inside the insulating layer body 1, and the insulating layer body 1 is provided with a first cavity 3, a second cavity 4, a third cavity 5, a fourth cavity 6 and a fifth cavity 7 from the inside to the outside. The interior of the first cavity 3 is uniformly filled with an inner protective insulating plate 8, the interior of the second cavity 4 is uniformly filled with a wire mesh layer 9, the interior of the third cavity 5 is uniformly filled with a silicon nitride composite plate 10, the interior of the fourth cavity 6 is uniformly filled with a rubber plate 11, and the interior of the fifth cavity 7 is filled with an outer insulating plate 12. The thickness of the inner protective insulating plate 8, the wire mesh layer 9, the silicon nitride composite plate 10, the rubber plate 11 and the outer insulating plate 12 are all the same, and the thickness is one millimeter. The inner protective insulating plate 8 filled in the first cavity 3 can directly protect the energized wire 2. In order to avoid damage caused by external scratches, the wire mesh layer 9 filled in the second cavity 4 greatly increases the hardness of the insulating layer body 1, and the silicon nitride composite plate 10 filled in the third cavity 5 effectively increases the wear resistance of the insulating layer body 1. The rubber plate 11 and the outer insulating plate 12 filled in the fourth cavity 6 and the fifth cavity 7 can greatly improve the toughness of the wires and the anti-scratch effect of the electric vehicle wires. The top and bottom of the insulating layer body 1 are provided with equidistantly arranged horizontal plates 13. In order to prevent the above-mentioned wires from being scratched, the raised horizontal plates 13 are used to block external forces. In addition, a multi-layer composite structure is provided to enhance the anti-scratch effect. This not only greatly increases the production cost of the wires, but also makes the wires thicker overall after production, and the raised structure on the surface is difficult to organize.

[0003] Therefore, how to effectively and cost-effectively prevent the surface of the wire from being scratched is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0025] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0026] For example, see Figure 2 Combined with Figure 3 , Figure 2 A three-dimensional diagram of the best embodiment of the anti-scratch wire of the utility model; Figure 3 This is a structural diagram of the optimal embodiment of the support part and the insulating sleeve of the utility model. Figures 2 to 3As shown, the utility model provides a scratch-proof wire, which includes, from the inside to the outside, a wire core 101, a protective layer 102 and an insulating sleeve 103, wherein the protective layer 102 is wound on the surface of the wire core 101, and the insulating sleeve 103 is arranged on the outer wall of the protective layer 102; in addition, a plurality of long grooves 104 are arranged on the protective layer 102, and at least one supporting portion 105 is arranged in each long groove 104, and the supporting portion 105 can maintain a certain support force while being able to bend at will, which can not only keep the wire 100 in a certain fixed shape, but also prevent external debris from directly contacting the surface of the insulating sleeve 103. As a preferred embodiment, the supporting portion 105 is a hard rubber rod or a rubber cortex is arranged on the metal wire. Specifically, the supporting portion 105 includes a hard rubber rod, and the supporting portion 105 includes a metal wire and a rubber cortex wrapped on the metal wire. As a preferred embodiment, the metal wire is an iron wire. The cross-section of the hard rubber rod and the metal wire with a rubber layer on the surface is circular or polygonal. Specifically, the cross-section of the support portion 105 is circular or polygonal, and the inner contour of the long groove 104 coincides with a part of the outer contour of the support portion 105. When the wire needs to be bent at a too small angle, the support portions 105 are arranged at equal intervals in the long groove 104, and a bending section is formed between two adjacent support portions 105. The angle of the wire 100 can be fixed at the bending section position, which will reduce the position deformation of the insulating sleeve 103. At the same time, the support portion 105 can be pulled in the long groove 104, so the position of the bending section can be changed, and the wire 100 can be bent into different length sections as needed. When the bending section is short, the deformation degree of the insulating sleeve 103 cannot be effectively reduced. When it is long, the wire 100 will be piled up at the bending position. Therefore, the length of the bending section is 1.2 times to 2 times the diameter of the insulating sleeve 103. Part of the support portion 105 protrudes from the surface of the insulating sleeve 103.

[0027] An overhead arc surface 106 is formed between two adjacent long grooves 104 and the surface of the insulating sleeve 103. Part of the support portion 105 extends outside the insulating sleeve 103, and the support portion 105 extends outside the insulating sleeve 103 to form a convex surface 107. When an external object contacts the wire 100, it will contact the part of the support portion 105 exposed outside the insulating sleeve 103, that is, contact the convex surface 107, which greatly reduces the probability of contact with the overhead arc surface 106, thereby reducing the probability of the surface of the insulating sleeve 103 being scratched, and playing a good protective effect on the wire core 101.

[0028] For example 2, please refer to Figure 2 Combined with Figure 3 .like Figures 2 to 3As shown, the utility model provides a scratch-proof wire, which includes, from the inside to the outside, a wire core 101, a protective layer 102 and an insulating sleeve 103, wherein the protective layer 102 is wound on the surface of the wire core 101, and the insulating sleeve 103 is arranged on the outer wall of the protective layer 102; in addition, a plurality of long grooves 104 are arranged on the protective layer 102, and at least one supporting portion 105 is arranged in each long groove 104, and the supporting portion 105 can maintain a certain support force while being able to bend at will, which can not only keep the wire 100 in a certain fixed shape, but also prevent external debris from directly contacting the surface of the insulating sleeve 103. As a preferred embodiment, the supporting portion 105 is a hard rubber rod or a rubber cortex is arranged on the metal wire. Specifically, the supporting portion 105 includes a hard rubber rod, and the supporting portion 105 includes a metal wire and a rubber cortex wrapped on the metal wire. As a preferred embodiment, the metal wire is an iron wire. The cross-section of the hard rubber rod and the metal wire with a rubber layer on the surface is circular or polygonal. Specifically, the cross-section of the support portion 105 is circular or polygonal, and the inner contour of the long groove 104 coincides with a part of the outer contour of the support portion 105. When the wire needs to be bent at a too small angle, the support portions 105 are arranged at equal intervals in the long groove 104, and a bending section is formed between two adjacent support portions 105. The angle of the wire 100 can be fixed at the bending section position, which will reduce the position deformation of the insulating sleeve 103. At the same time, the support portion 105 can be pulled in the long groove 104, so the position of the bending section can be changed, and the wire 100 can be bent into different length sections as needed. When the bending section is short, the deformation degree of the insulating sleeve 103 cannot be effectively reduced. When it is long, the wire 100 will be piled up at the bending position. Therefore, the length of the bending section is 1.2 times to 2 times the diameter of the insulating sleeve 103. Part of the support portion 105 protrudes from the surface of the insulating sleeve 103.

[0029] An overhead arc surface 106 is formed between two adjacent long grooves 104 and the surface of the insulating sleeve 103. Part of the support portion 105 extends outside the insulating sleeve 103, and the support portion 105 extends outside the insulating sleeve 103 to form a convex surface 107. When an external object contacts the wire 100, it will contact the part of the support portion 105 exposed outside the insulating sleeve 103, that is, contact the convex surface 107, which greatly reduces the probability of contact with the overhead arc surface 106, thereby reducing the probability of the surface of the insulating sleeve 103 being scratched, and playing a good protective effect on the wire core 101.

[0030] Please continue reading Figure 4 , Figure 4 FIG. 2 is a structural diagram of the optimal embodiment of the concave pit of the utility model. Figure 4As shown, in order to reduce the possibility of sharp objects sliding onto the insulating sleeve 103 after contacting the raised surface 107, a plurality of concave pits 1051 are provided on the surface of the support portion 105. The concave pits 1051 are circular or polygonal. The depth of the concave pits 1051 is 0.1-0.35 mm, which can avoid the probability of sharp or small objects contacting the insulating sleeve 103.

[0031] In summary, by providing the support portion 105, the electric wire 100 can be bent and shaped at will, thereby improving the convenience of arranging the electric wire 100; by making part of the support portion 105 protrude, the probability of contact with the overhead arc surface 106 is greatly reduced, thereby reducing the probability of the surface of the insulating sleeve 103 being scratched, and having a good protective effect on the wire core 101; by providing the pit 1051, the probability of contact between sharp or small objects and the insulating sleeve 103 is avoided, thereby further improving the protective effect on the electric wire 100.

[0032] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
