Description

Technical Field

[0001] The utility model relates to the technical field of multi-core wires, in particular to a multi-core wire that is easy to arrange. Background Art

[0002] The existing multi-core cable structure is relatively common, such as a multi-core cable with patent number 202320618674.2. For details, please refer to Figure 1 ,like Figure 1 As shown, the multi-core cable includes a protective component 1, a protective layer 2 is provided inside the protective component 1, a limiting layer 3 is provided on the inner wall of the protective layer 2, a plurality of line cavities 4 are provided inside the limiting layer 3, an insulating layer 5 is provided inside the plurality of line cavities 4, and a cable body 6 is provided inside the plurality of insulating layers 5; the protective component 1 includes an outer shell 101, a fireproof layer 102 is provided on the inner wall of the outer shell 101, a protective layer 103 is provided on the inner wall of the fireproof layer 102, and a plurality of wire cavities 4 are embedded in the inner wall of the protective layer 103. Spring 104, several springs 104 are provided with a rubber clamping pad 105 at one end away from the protective layer 103. The multi-core wire production process in the related art is roughly divided into two steps, the core wire twisting process and the outer protective layer covering process. The above-mentioned multi-core wire cable sets a spring between the protective layer and the core, which makes the overall production steps more complicated and increases the production cost. In addition, the outer contour of the protective layer 2 formed by protection is an arc contour. During use, the contact area is small when it is against the installation surface, which increases the difficulty of positioning.

[0003] Therefore, it is necessary to provide a multi-core wire that is easy to arrange. Utility Model Content

[0025] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0026] See also Figure 2 See also Figure 3 , Figure 2 A three-dimensional diagram of an optimal embodiment of an easily arranged multi-core wire of the utility model; Figure 3 This is a schematic structural diagram of an optimal embodiment of an easily arranged multi-core wire of the utility model. Figure 1 As shown, at least one embodiment provides a multi-core cable that is easy to arrange, comprising: multiple cores 30, an inner sheath 20, and an outer protective layer 10. Specifically, the inner sheath 20 is provided on the surface of the multiple cores 30, and the outer protective layer 10 is provided on the surface of the inner sheath 20. To facilitate the smooth and orderly arrangement of the multi-core cable on a use surface, a cut surface 40 is provided on the inner sheath 20 and the outer protective layer 10. Specifically, a portion of the cable, after being coated into a circular contour, is cut away so that the cut surface 40 is aligned with the plane of the use surface, preventing the cable from twisting and bending, increasing the contact area, and reducing the difficulty of cable arrangement. It should be noted that a limiting slot 50 is provided at the center of the cut surface 40, and a metal wire 70 is disposed within the limiting slot 50. The overall shape and curvature of the cable can be changed by freely bending the metal wire 70, making the cable body freely configurable and further reducing the difficulty of cable arrangement. The cross-section of the limiting slot 50 is 3 / 4 of a circular arc. The metal wire 70 is embedded in the arc.

[0027] Please continue reading Figure 3 Combined with Figure 4 , Figure 4 This is a schematic diagram of the structure of the optimal embodiment of the protective component of the utility model. Figure 3 and Figure 4 As shown, a protective assembly 60 is provided on the surface of the core 30 near the edge of the inner sheath 20. The inner sheath 20 covers the protective assembly 60 and the surface of the core 30. The protective assembly 60 includes a protective spacer 61, which is the same length as the core 30 and is used to protect the core 30 near the weaker part of the sheath. In addition, the protective spacer 61 is attached to the core 30 before the core 30 is covered by the inner sheath 20. The outer contour of the protective spacer 61 is "crescent-shaped", so that the thickest part of the protective spacer 61 corresponds to the thinnest part of the sheath.

[0028] Please continue reading Figure 3 Combined with Figure 4 ,like Figure 3 and Figure 4 As shown. The protective spacer 61 has an arc-shaped convex surface 62, which abuts against the inner wall of the inner coating layer 20. The protective spacer 61 also has an arc-shaped concave surface 63 corresponding to the arc-shaped convex surface 62, which abuts against the inner wall of the wire core 30. Short wires 64 are provided on the arc-shaped concave surface 63, and the short wires 64 are squeezed into a multi-pleated shape by the protective spacer 61 and the wire core 30. The short wires 64 are made of rubber. Compared with springs, the short wires 64 and the protective spacer 61 are integrally molded, and the production process is relatively simple and the cost is low. The short wires 64 are wrinkled between the protective spacer 61 and the wire core 30, further enhancing the protective effect of the protective spacer 61.

[0029] In summary, by providing the cut surface 40 and the metal wire, the wire body is prevented from twisting and bending, and the contact area is increased, so that the wire body can be shaped freely, reducing the difficulty of wiring; by providing the protective component 60, the protection effect of the wire core 30 is enhanced, and damage to the thinnest protection position of the wire core 30 caused by deformation and bending is avoided; the aging speed of the wire body during use is delayed; and by providing the short wire 64, the protection effect of the protective spacer 61 on the wire core 30 is further enhanced.

[0030] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
