Description

Technical Field

[0001] The utility model relates to the technical field of cable structures, in particular to a flexible power cable. Background Art

[0002] Flexible power cables are commonly used in power transmission, data transfer, communication control, and other applications. To distinguish between cable models, production batch numbers, and other information, flexible power cables are typically labeled with information (including cable model and production batch number) to prevent mismatching.

[0003] like Figure 1 and Figure 2 As shown, the existing practice is generally to set an adhesive layer (not shown) on one side surface of the label 51, and wrap the label 51 around the flexible power cable 5 so that the label 51 adheres to the surface of the flexible power cable 5 through the adhesive layer. At the same time, the two ends of the label 51 are also bonded together through the adhesive layer to fix the label 51 to the flexible power cable 5.

[0004] However, in the flexible power cable 5 of the above-described structure, although the label 51 is generally made of adhesive tape, which has a certain degree of weather resistance, since the label 51 is directly exposed to the air, it is easy to lose the label information after long-term use due to problems such as damage, water immersion, or falling off of the label 51, thereby affecting the subsequent identification of the cable information. At the same time, when the coded information on the label 51 is long, in order to facilitate the identification of the coded information, the label 51 needs to be set relatively large (that is, the size of the coded information can be set relatively large so that it can be clearly seen). However, the larger the label 51, the more space it takes up, which is not conducive to the miniaturization design of the label 51 and affects its aesthetics. Utility Model Content

[0005] The purpose of the utility model is to provide a flexible power cable, which uses a lens layer to wrap and cover the label layer, which not only can provide good protection for the label layer, but also the lens layer can amplify the label information on the label layer, so that the label layer can adopt a miniaturized design.

[0006] The utility model provides a flexible power cable, comprising a cable body, a label layer being provided on the surface of the cable body, and a lens layer being sleeved on a position on the cable body corresponding to the label layer; the lens layer is a tubular structure, covering the label layer, and a hoop of the lens layer is fixed on the cable body, and the lens layer can amplify the label information on the label layer.

[0007] In one feasible manner, the lens layer includes a lens sleeve and a transparent fixing sleeve. The lens sleeve is sleeved outside the label layer, and the lens sleeve at least covers the label information on the label layer. The lens sleeve can amplify the label information on the label layer; the transparent fixing sleeve is sleeved outside the lens sleeve, and the transparent fixing sleeve covers the lens sleeve and the label layer. The transparent fixing sleeve is fixed to the cable body through a hoop.

[0008] In one achievable manner, the transparent fixing sleeve is a transparent heat shrinkable sleeve that can shrink after being heated.

[0009] In one achievable manner, viewed from a longitudinal section of the lens tube, the inner surface of the lens tube is a flat structure in contact with the label layer, and the outer surface of the lens tube is a curved structure convex outward.

[0010] In one feasible manner, the lens sleeve completely covers the label layer; along the axial direction of the cable body, the length of the transparent fixing sleeve is greater than the length of the lens sleeve, and the opposite ends of the transparent fixing sleeve respectively extend to opposite sides of the lens sleeve.

[0011] In one feasible manner, the lens layer includes a lens portion and a fixing portion, and the fixing portion is connected to opposite sides of the lens portion along the axial direction of the cable body; the lens portion is arranged corresponding to the label layer, and the lens portion can amplify the label information on the label layer; the fixing portion extends to opposite sides of the label layer, and the fixing portion is fixed to the cable body by a hoop.

[0012] In one achievable manner, the fixing portion is a heat shrinkable portion that can shrink after being heated.

[0013] In one achievable manner, viewed from a longitudinal section of the lens portion, the inner surface of the lens portion is a flat structure in contact with the label layer, and the outer surface of the lens portion is a curved structure convex outward.

[0014] In one achievable manner, the label layer includes a transparent base layer and label information arranged on a surface of the transparent base layer. A reflective layer is provided between the label layer and the surface of the cable body, and the reflective layer is arranged corresponding to the label layer.

[0015] In one achievable manner, a positioning mark is provided on the surface of the cable body, the label layer is provided corresponding to the positioning mark, and the label layer covers the positioning mark.

[0016] The flexible power cable provided by the present invention utilizes a lens layer disposed on the cable body to wrap and cover the label layer. This not only effectively secures the label layer and prevents it from falling off, but also completely isolates it from the external environment, effectively protecting it from water and damage, ensuring the integrity of the label information and extending its service life. Furthermore, the lens layer acts as a magnifying glass, amplifying the label information on the label layer. This magnifying effect allows for clear viewing of the label information, eliminating the need for a large label layer or label information size. This allows for a compact design of the label layer, saving space and enhancing aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] First embodiment

[0031] like Figures 3 to 7 As shown, the first embodiment of the present invention provides a flexible power cable, comprising a cable body 1, comprising an insulating protective layer (not shown) and a plurality of conductive wires (not shown) disposed within the insulating protective layer. A label layer 2 is provided on the surface of the cable body 1, on which label information 20 is provided. The label information 20 includes, for example, cable coding information (including the cable model, production batch number, etc.). Depending on the size of the label layer 2, the label layer 2 can be bent into a cylindrical or semi-circular structure (in this embodiment, the label layer 2 is cylindrical). A lens layer 3 is provided on the cable body 1 at a position corresponding to the label layer 2. The lens layer 3 is a tubular structure and is disposed outside the label layer 2, completely covering the label layer 2. The lens layer 3 is secured to the cable body 1 by a hoop, thereby wrapping and securing the label layer 2 to the cable body 1. Furthermore, the lens layer 3 has a magnifying effect, meaning that the lens layer 3 acts as a magnifying glass, capable of amplifying the label information 20 on the label layer 2.

[0032] The flexible power cable provided by the embodiment of the present invention has a lens layer 3 sleeved on the cable body 1, which is used to wrap and cover the label layer 2. This method not only better fixes the label layer 2 and prevents it from falling off, but also completely isolates the label layer 2 from the external environment, providing good protection for the label layer 2, preventing it from being soaked by water and damaged, ensuring the integrity of the label information 20, and extending the service life of the label layer 2. At the same time, the lens layer 3 acts as a magnifying glass, amplifying the label information 20 on the label layer 2. The magnifying effect of the lens layer 3 allows the label information 20 to be clearly visible, eliminating the need to enlarge the size of the label layer 2 and the label information 20 (smaller than conventional sizes). This allows the label layer 2 to be miniaturized, saving space and improving aesthetics.

[0033] like Figures 4 to 7 As shown, as an embodiment, the lens layer 3 has a double-layer sleeve structure. The lens layer 3 includes a lens sleeve 31 and a transparent fixing sleeve 32. Both the lens sleeve 31 and the transparent fixing sleeve 32 are transparent tubular structures. The lens sleeve 31 is sleeved over the label layer 2, covering at least the label information 20 on the label layer 2 and magnifying the label information 20 on the label layer 2. The transparent fixing sleeve 32 is sleeved over the lens sleeve 31, completely covering the lens sleeve 31 and the label layer 2. The transparent fixing sleeve 32 is fixed to the cable body 1 through a hoop, thereby enveloping and fixing the lens sleeve 31 and the label layer 2 to the cable body 1.

[0034] Specifically, in this embodiment, the lens sleeve 31 acts as a magnifying glass, primarily providing magnification; the transparent fixing sleeve 32 primarily provides fixing and protection; and the lens sleeve 31 also protects the label layer 2. Because the lens layer 3 is separated into two components, the lens sleeve 31 and the transparent fixing sleeve 32, the lens sleeve 31 and the transparent fixing sleeve 32 can be manufactured separately, facilitating fabrication of the components.

[0035] like Figure 7 As shown in FIG. 1 , as one embodiment, a longitudinal cross-section of lens tube 31 shows that the inner surface of lens tube 31 is a flat structure (i.e., a planar structure) that is in contact with label layer 2. The outer surface of lens tube 31 is an outwardly convex curved surface structure. In other words, lens tube 31 is thick in the middle and thin at the edges, meaning that lens tube 31 is equivalent to a plano-convex lens. In this embodiment, the outer surface of lens tube 31 is an outwardly convex arc surface structure, and the curvature of the outer surface of lens tube 31 can be determined based on the desired magnification effect.

[0036] In one embodiment, the transparent fixing sleeve 32 is a transparent heat-shrinkable sleeve that shrinks upon heating. Specifically, during assembly, after the transparent fixing sleeve 32 is placed over the cable body 1, it is heated (e.g., using a heat gun) to shrink, tightly securing the transparent fixing sleeve 32 to the cable body 1. This in turn secures the lens sleeve 31 and label layer 2 to the cable body 1. The transparent heat-shrinkable sleeve 32 facilitates assembly. Of course, in other embodiments, the transparent fixing sleeve 32 can also be secured to the cable body 1 using glue or other methods.

[0037] As an embodiment, the thermal melting temperature of the lens sleeve 31 is greater than the shrinkage temperature (i.e., the heating shrinkage temperature) of the transparent fixed sleeve 32, thereby preventing the lens sleeve 31 from shrinking or deforming due to thermal melting during the heating process of the transparent fixed sleeve 32, thereby preventing the lens sleeve 31 from affecting its magnification effect.

[0038] As an embodiment, the material of the lens tube 31 can be PMMA (acrylic), PC (polycarbonate), etc. The material of the transparent heat shrink tube can refer to the existing technology and will not be described here.

[0039] like Figure 7 As shown, as an embodiment, the lens tube 31 completely covers the label layer 2, that is, along the axial direction X of the cable body 1, the length of the lens tube 31 is greater than or equal to the length of the label layer 2 (in this embodiment, the length of the lens tube 31 is equal to the length of the label layer 2), so that the lens tube 31 can provide good protection and magnification for the label layer 2.

[0040] like Figure 7 As shown, as an embodiment, along the axial direction X of the cable body 1, the length of the transparent fixing sleeve 32 is greater than the length of the lens sleeve 31, and the opposite ends of the transparent fixing sleeve 32 extend to the opposite sides of the lens sleeve 31, so as to achieve a good wrapping effect on the lens sleeve 31 and the label layer 2; at the same time, the protruding portions on both sides of the transparent fixing sleeve 32 will fit tightly with the surface of the cable body 1, thereby improving the sealing effect.

[0041] In one embodiment, the lens sleeve 31 is fixed to the transparent fixing sleeve 32 by adhesive bonding, and the label layer 2 is fixed to the lens sleeve 31 by adhesive bonding. During manufacturing, the lens sleeve 31 can be pre-bonded to the inner surface of the transparent fixing sleeve 32, and the label layer 2 can be pre-bonded to the inner surface of the lens sleeve 31, so that the transparent fixing sleeve 32, lens sleeve 31, and label layer 2 are fixed together. The transparent fixing sleeve 32 is then sleeved onto the cable body 1 and then heated to fix it, thereby facilitating manufacturing (the transparent fixing sleeve 32, lens sleeve 31, and label layer 2 do not need to be separately sleeved onto the cable body 1 and then positioned).

[0042] like Figures 4 to 7 As shown, as an embodiment, the label layer 2 includes a transparent base layer 21 and label information 20 disposed on the surface of the transparent base layer 21 (i.e., the label layer 2 is a transparent label). A reflective layer 4 is disposed between the label layer 2 and the surface of the cable body 1, and the reflective layer 4 is disposed corresponding to the label layer 2. The reflective layer 4 can reflect external ambient light to increase the reflected brightness; the reflective layer 4 is combined with the lens layer 3 to improve the display clarity.

[0043] Specifically, in this embodiment, the label information 20 is disposed on the outer surface of the transparent base layer 21. Of course, the label information 20 can also be disposed on the inner surface of the transparent base layer 21. When no reflective layer 4 is disposed between the label layer 2 and the surface of the cable body 1, the label layer 2 can also be an opaque label. In this case, the label information 20 can only be disposed on the outer surface of the transparent base layer 21.

[0044] As an embodiment, the reflective layer 4 is a reflective metal layer (specifically, a metal aluminum layer, which can be formed on the inner surface of the label layer 2 by spraying, etc.) provided on the inner surface of the label layer 2. Of course, in other embodiments, the reflective layer 4 can also be provided on the surface of the cable body 1, or the reflective layer 4 can be a separate layer of metal film.

[0045] like Figure 4 As shown, as an embodiment, a positioning mark 11 is provided on the surface of the cable body 1 , the label layer 2 is provided corresponding to the positioning mark 11 , and the label layer 2 covers the positioning mark 11 .

[0046] Specifically, the positioning mark 11 is used for positioning and installing the label layer 2 (i.e., the label layer 2 is set at the positioning mark 11), which facilitates production and can ensure product consistency (i.e., ensures that the position of the label layer 2 on each flexible power cable is the same); and, since the label layer 2 covers the positioning mark 11, that is, the positioning mark 11 is covered, it does not affect the aesthetics. The positioning mark 11 can specifically be an identification line set on the surface of the cable body 1 (for example, the cable body 1 is black and the identification line is white). At the same time, when the reflective layer 4 is set on the surface of the cable body 1, there is no need to additionally set the positioning mark 11 (i.e., the reflective layer 4 acts as the positioning mark 11).

[0047] The flexible power cable provided by the embodiment of the present invention utilizes a lens layer 3 provided on the cable body 1 to wrap and cover the label layer 2. This not only better secures the label layer 2 and prevents it from falling off, but also completely isolates the label layer 2 from the external environment, effectively protecting the label layer 2 from water and damage, ensuring the integrity of the label information 20 and extending the service life of the label layer 2. Furthermore, the lens layer 3 acts as a magnifying glass, amplifying the label information 20 on the label layer 2. The magnifying effect of the lens layer 3 allows the label information 20 to be clearly visible, eliminating the need to enlarge the size of the label layer 2 and the label information 20. This allows the label layer 2 to be miniaturized, saving space and improving aesthetics.

[0048] Second embodiment

[0049] like Figures 8 to 10 As shown, the flexible power cable provided by the second embodiment of the present invention is substantially the same as that of the first embodiment, except that the structure of the lens layer 3 is different.

[0050] Specifically, in this embodiment, the lens layer 3 is a single-layer sleeve structure. The lens layer 3 includes a lens portion 33 and a fixing portion 34. Both the lens portion 33 and the fixing portion 34 are transparent tubular structures (of course, in other embodiments, the fixing portion 34 may also be an opaque structure). Along the axial direction X of the cable body 1, the fixing portions 34 are connected to opposite sides of the lens portion 33. The lens portions 33 are positioned corresponding to the label layer 2 and are capable of amplifying the label information 20 on the label layer 2. The fixing portions 34 extend to opposite sides of the label layer 2 and are secured to the cable body 1 in a hooped manner, thereby wrapping and securing the label layer 2 to the cable body 1.

[0051] Specifically, in this embodiment, the lens portion 33 is equivalent to a magnifying glass and mainly performs a magnifying function; the fixing portion 34 mainly performs a fixing function. The lens portion 33 and the fixing portion 34 can be an integral structure or a separate structure, and can be connected together by bonding or other means.

[0052] like Figure 10 As shown in FIG. 1 , as an embodiment, from a longitudinal cross-section of the lens portion 33, the inner surface of the lens portion 33 is a flat structure (i.e., a planar structure) that is in contact with the label layer 2, while the outer surface of the lens portion 33 is an outwardly convex curved surface structure. In other words, the lens portion 33 is thick in the middle and thin at the edges, i.e., the lens portion 33 is equivalent to a plano-convex lens. In this embodiment, the outer surface of the lens portion 33 is an outwardly convex arc surface structure, and the curvature of the outer surface of the lens portion 33 can be determined according to the desired magnification effect.

[0053] In one embodiment, the fixing portion 34 is a heat-shrinkable portion that shrinks upon heating. That is, during assembly, after the lens layer 3 is placed on the cable body 1, the fixing portion 34 is heated (e.g., using a heat gun). This heat causes the fixing portion 34 to shrink, tightly encircling and securing the cable body 1. This allows the lens layer 3 to wrap around the label layer 2 and secure it to the cable body 1. Of course, in other embodiments, the fixing portion 34 can also be secured to the cable body 1 using glue or other methods.

[0054] As an embodiment, the thermal melting temperature of the lens portion 33 is greater than the shrinkage temperature (i.e., the heat shrinkage temperature) of the fixing portion 34, thereby preventing the lens portion 33 from shrinking or deforming during the heating process of the fixing portion 34, thereby affecting its magnification effect. In this case, the fixing portion 34 and the lens portion 33 can adopt a separate structure, each made of different materials. Of course, in other embodiments, the fixing portion 34 and the lens portion 33 can also be made of the same material (for example, they are a one-piece structure). In this case, when heating the fixing portion 34, it is necessary to be careful not to heat the lens portion 33 (for example, heating the fixing portion 34 at a single point) to avoid shrinking and deforming the lens portion 33.

[0055] In one embodiment, the label layer 2 and the lens layer 3 are fixed by adhesive bonding. During production, the label layer 2 can be pre-bonded to the inner surface of the lens layer 3, and then the lens layer 3 is placed on the cable body 1. The fixing portion 34 is then heated and fixed, thereby facilitating production (the label layer 2 and the lens layer 3 do not need to be placed on the cable body 1 separately and then positioned).

[0056] Other structures and principles of this embodiment are the same as or similar to those of the first embodiment and are not described in detail here.

[0057] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
