Description

Technical Field

[0001] The present application relates to the field of power cables, and in particular to an anti-aging power cable for new energy vehicles. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They are cable products used to transmit and distribute high-power electrical energy in the trunk lines of power systems.

[0003] When charging new energy vehicles, they usually need to use a charging power cable. In order to increase the service life of the cable, the power cable mainly includes a conductor layer, a first protective layer, a shielding layer, and a second protective layer. The first protective layer and the second protective layer provide double protection for the conductor layer, so that the external environment is not easy to affect the normal operation of the conductor layer. The first protective layer and the second protective layer are both made of silicone.

[0004] Since new energy vehicles need to be charged frequently, cables need to be used frequently, and during the use of the cables, they need to be frequently pulled and bent. After long-term use, the first protective layer and the second protective layer made of silicone are prone to folding at the frequent bending locations, which leads to a decrease in the service life of the cable, so there is room for improvement. Utility Model Content

[0005] In order to improve the above problems, the present application provides an anti-aging power cable for new energy vehicles.

[0006] The present application provides an anti-aging power cable for new energy vehicles, which adopts the following technical solution:

[0007] An anti-aging power cable for new energy vehicles comprises a conductor layer, an inner protective layer, a shielding layer and an outer protective layer arranged in sequence from the inside to the outside, wherein the inner protective layer and the outer protective layer are both provided with a support layer, wherein the support layer comprises a tensile layer and a support layer, and the tensile layer is arranged on a side of the support layer away from the conductor layer.

[0008] By adopting the above technical solution, during the actual use of the cable, the inner protective layer and the outer protective layer provide double protection for the conductor body, so that the external environment is not easy to affect the conductor layer. At the same time, under the action of the tensile layer, the tensile performance of the inner and outer protective layers is improved, and the supporting layer improves the supporting capacity of the inner and outer protective layers, so that the inner and outer protective layers are not easy to be folded after long-term use, so that the inner and outer protective layers can provide relatively stable protection for the conductor layer, thereby extending the service life of the cable as a whole.

[0009] Preferably, the support layer includes a plurality of support columns, and the plurality of support columns are arranged in the inner protective layer or the outer protective layer at corresponding positions along the circumference of the conductor layer. Each of the support columns includes a plurality of support bars, and two adjacent support bars are connected by a connecting bar.

[0010] By adopting the above technical scheme, each support column formed by the support strips and the connecting strips provides support for the inner protective layer and the outer protective layer at the corresponding positions, thereby improving the structural strength of the inner protective layer and the outer protective layer, making it less likely for the inner protective layer and the outer protective layer to be folded after long-term use, thereby improving the protection ability of the inner protective layer and the outer protective layer to the conductor layer, thereby extending the overall service life of the cable.

[0011] Preferably, each of the support bars is provided with a support arc surface on one side close to an adjacent support bar.

[0012] By adopting the above technical scheme, the supporting arc surface, on the one hand, increases the contact area between the supporting bar and the inner protective layer at the corresponding position or the outer protective layer at the corresponding position, and improves the connection stability between the supporting bar and the inner protective layer at the corresponding position or the outer protective layer at the corresponding position; on the other hand, when the cable is bent, the supporting arc surface provides support for the inner protective layer and the outer protective layer, so that the cable bending place is not prone to edge folding, thereby achieving the function of extending the service life of the cable.

[0013] Preferably, each of the support bars is provided with a bending ring groove.

[0014] By adopting the above technical solution, the bending ring groove facilitates the support bar to bend simultaneously when the cable is bent, so that the support bar is not easy to affect the use of the cable, so that the cable can be used more stably.

[0015] Preferably, the inner wall of the bending annular groove is provided with a bending arc surface.

[0016] By adopting the above technical solution, the curved surface improves the structural strength of the inner wall of the bending ring groove, making it difficult for the support bar to break when bending, thereby further facilitating the use of the cable.

[0017] Preferably, the anti-tensile layer comprises an anti-tensile fiber layer, and the anti-tensile fiber layer is coated on a side of the stabilizing layer away from the conductor layer.

[0018] By adopting the above technical solution, the tensile fiber layer improves the tensile resistance of the outer protective layer and the inner protective layer, so that the inner protective layer and the outer protective layer are not broken when the cable is used, thereby further extending the service life of the cable.

[0019] Preferably, the shielding layer comprises a copper wire braided shielding layer, one side of the copper wire braided shielding layer is connected to the inner protective layer, and the other side of the copper wire braided shielding layer is connected to the outer protective layer.

[0020] By adopting the above technical solution, the copper wire braided shielding layer reduces the possibility of electromagnetic interference energy generated during signal transmission causing data transmission speed to slow down, reduces distortion, and improves the stability of the cable during use.

[0021] Preferably, the thickness of the outer protective layer and the inner protective layer ranges from 1.0 mm to 2.0 mm.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By setting the inner protective layer, the outer protective layer, the tensile layer and the support layer, the inner protective layer and the outer protective layer first provide double protection for the conductor layer, while the tensile layer improves the tensile resistance of the inner protective layer and the outer protective layer, and the support layer improves the support capacity of the inner protective layer and the outer protective layer, so that the inner protective layer and the outer protective layer can protect the conductor layer more stably, thereby extending the service life of the cable;

[0024] 2. By setting the bending ring groove, it is convenient for the support bar at the corresponding position to bend when the cable is bent. At the same time, the bending ring groove increases the stability of the bending part of the support bar, making it less likely for the support bar to break;

[0025] 3. By setting the supporting arc surface, on the one hand, the contact area between the support bar and the outer protective layer at the corresponding position or the inner protective layer at the corresponding position is increased, thereby improving the connection stability between the support bar and the outer protective layer or the inner protective layer; on the other hand, when the cable is bent, the supporting arc surface provides support for the inner and outer protective layers, making it less likely that the cable will bend at the bend.

[0029] The following is combined with Figure 1-2 This application is described in further detail.

[0030] The present application discloses an anti-aging power cable for new energy vehicles. Figure 1 and Figure 2, an anti-aging power cable for new energy vehicles, comprising a conductor layer 1, an inner protective layer 2, a shielding layer 3 and an outer protective layer 4, one side of the inner protective layer 2 is connected to the conductor layer 1, and the other side is connected to the shielding layer 3, and the side of the shielding layer 3 facing away from the inner protective layer 2 is connected to the outer protective layer 4. A stabilizing layer 5 is provided in both the inner protective layer 2 and the outer protective layer 4, and the stabilizing layer 5 includes a tensile layer 51 and a supporting layer 52, the tensile layer 51 is connected to the supporting layer 52, and the tensile layer 51 is provided on the side of the supporting layer 52 facing away from the conductor layer 1.

[0031] During the actual use of the cable, the inner protective layer 2 and the outer protective layer 4 first provide double protection for the conductor layer 1, so that the external environment is not likely to affect the conductor layer 1. At the same time, the tensile layer 51 improves the tensile properties of the inner protective layer 2 and the outer protective layer 4, so that the inner protective layer 2 and the outer protective layer 4 are not likely to be folded during use, and the support layer 52 improves the support capacity of the outer protective layer 4 and the inner protective layer 2, and improves the protection capacity of the inner protective layer 2 and the outer protective layer 4 to the conductor layer 1, thereby extending the service life of the entire cable.

[0032] Reference Figure 1 The conductor layer 1 is made of a plurality of copper wires, the inner protective layer 2 and the outer protective layer 4 are both made of silicone, and the thickness of the inner protective layer 2 and the outer protective layer 4 ranges from 1.0 mm to 2.0 mm. The shielding layer 3 includes a copper wire braided shielding layer 3, one side of the copper wire braided shielding layer 3 is connected to the inner protective layer 2, and the other side is connected to the outer protective layer 4, and the copper wire braided shielding layer 3 is woven from a plurality of tinned copper wires. The copper wire braided shielding layer 3 reduces the possibility of slowing down the data transmission speed caused by the electromagnetic interference energy generated during the signal transmission process, reduces the distortion phenomenon, and improves the stability of the cable during use.

[0033] Reference Figure 2 The support layer 52 includes a plurality of support columns 521, and each support column 521 is evenly arranged in the inner protective layer 2 at a corresponding position or the outer protective layer 4 at a corresponding position along the circumference of the conductor layer 1. Each support column 521 includes a plurality of support bars 5211, and two adjacent support bars 5211 are connected by a connecting bar 5212. The support bars 5211 and the connecting bars 5212 are both made of ETPU elastic particles. At this time, the support column 521 improves the overall structural strength of the inner protective layer 2 and the outer protective layer 4, and improves the protective ability of the outer protective layer 4 and the inner protective layer 2 to the conductor layer 1. The support column 521 made of ETPU elastic particles also improves the elastic potential energy of the inner protective layer 2 and the outer protective layer 4, so that the cable is not prone to folding during use, thereby extending the service life of the cable.

[0034] Reference Figure 2In order to improve the supporting capacity of the support column 521, each support bar 5211 is provided with a support arc surface 6 on one side close to the adjacent support bar 5211. The support arc surface 6 increases the contact area between the support bar 5211 and the inner protective layer 2 at the corresponding position or the outer protective layer 4 at the corresponding position, and improves the connection stability between the support bar 5211 and the inner protective layer 2 at the corresponding position or the outer protective layer 4 at the corresponding position. On the other hand, when the cable is bent, the support arc surface 6 provides support for the inner protective layer 2 and the outer protective layer 4, so that the cable bending place is not prone to folding, thereby achieving the function of extending the service life of the cable.

[0035] Reference Figure 2 Each support bar 5211 is provided with a bending ring groove 7, and the inner wall of the bending ring groove 7 is provided with a bending arc surface 71. The bending ring groove 7 facilitates the support bar 5211 to bend simultaneously when the cable is bent, so that the support bar 5211 is not likely to affect the use of the cable, so that the cable can be used more stably. At the same time, the bending arc surface 71 improves the structural strength of the inner wall of the bending ring groove 7, so that the support bar 5211 is not likely to break when it is bent, thereby further facilitating the use of the cable.

[0036] Reference Figure 1 and Figure 2 The tensile layer 51 includes a tensile fiber layer, which is coated on the side of the stabilizing layer 5 away from the conductor layer 1. The tensile fiber layer is woven from fiber ropes. The woven tensile fiber layer improves the structural strength of the tensile fiber layer itself, so that the tensile layer 51 can more stably improve the structural strength of the inner protective layer 2 and the outer protective layer 4, thereby reducing the possibility of breakage on the cable surface during the use of the cable.

[0037] The implementation principle of an anti-aging power cable for new energy vehicles in the embodiment of the present application is as follows: during the actual use of the cable, the outer protective layer 4 and the inner protective layer 2 provide double protection for the conductor layer 1, so that external impurities are not easy to affect the work of the conductor layer 1, thereby improving the stability of the cable during use. At the same time, the support layer 52 in the inner protective layer 2 and the outer protective layer 4 improves the supporting capacity of the inner protective layer 2 and the outer protective layer 4, that is, improves the protection capacity of the inner protective layer 2 and the outer protective layer 4 to the conductor layer 1, so that the cable surface is not prone to folding. And the tensile layer 51 improves the tensile capacity of the inner protective layer 2 and the outer protective layer 4, reduces the phenomenon of breakage during the use of the cable, thereby improving the service life of the cable.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
