Description
Technical Field
[0001] The utility model relates to the technical field of cables, and in particular to a cable for new energy vehicles. Background Art
[0002] At present, new energy vehicles generally refer to energy vehicles other than gasoline and diesel engines, generally referring to electric vehicles. When in use, electric vehicles generally transfer the electrical energy in the battery of the vehicle to the motor and other electrical components on the vehicle through cables, so that the car can work normally.
[0003] Existing cables for new energy vehicles generally consist of a core wire wrapped in an insulating sheath. However, during use, the core wire generates heat when transmitting electrical energy. Since the heat generated by the core wire in existing cables is blocked by the insulating sheath, the heat dissipation is slow and the heat dissipation effect is poor. Furthermore, since the core wire of the cable is only wrapped in an insulating sheath, its tensile strength is poor, making it easily broken by external forces during use, resulting in poor performance. To address this issue, we propose a cable for new energy vehicles. Utility Model Content
[0004] The purpose of the present utility model is to solve the above-mentioned shortcomings in the prior art and to propose a cable for new energy vehicles.
[0005] In order to achieve the above-mentioned object, the utility model adopts the following technical solution: a cable for new energy vehicles is designed, comprising an insulating sleeve, wherein a plurality of core wires are coaxially arranged inside the insulating sleeve, a first heat-conducting layer is connected to the outer surface of the insulating sleeve, and a tensile layer is coaxially connected to the outer surface of the first heat-conducting layer;

[0008] Connecting blocks are installed at both ends of the thermal conductive sheet. A limit block is installed on the side of each thermal conductive ring close to the connecting block. The limit block is in a "U" shape, and one side of the connecting block extends into the inside of the limit block.
[0009] An adhesive layer is installed on one side of the inner portion of the limiting block, and the side surface of the connecting block is glued together with the inner side surface of the limiting block through the adhesive layer.
[0010] Preferably, the core wires are twisted together.
[0011] Preferably, the tensile layer is made of galvanized copper wire material.
[0012] Preferably, the electromagnetic shielding layer is made of aluminum foil material.
[0013] Preferably, connecting sleeves are extended from both sides of each heat-conducting ring, and the connecting sleeves are sleeved on the second heat-conducting layer.
[0014] Preferably, the heat conducting sheet is spirally arranged and is made of heat conducting silicone material.
[0015] Preferably, the outer surface of the second heat-conducting layer is coaxially connected to a heat-conducting silicone sleeve, the heat-conducting ring and the heat-conducting plate are both located inside the heat-conducting silicone sleeve, and the inner surfaces of the heat-conducting ring and the heat-conducting plate are in contact with the inner surface of the heat-conducting silicone sleeve.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] Reference Figures 1-4 A cable for new energy vehicles includes an insulating sleeve 2, and a plurality of core wires 1 are coaxially arranged inside the insulating sleeve 2. The core wires 1 can transmit power from the battery on the new energy vehicle to other electrical equipment on the vehicle, so that the electrical equipment can work normally.
[0026] It should be noted that the core wires 1 are twisted together, which can increase the structural strength of the core wire 1 and prevent the core wire 1 from being broken due to external forces during use.
[0027] like Figure 1 and Figure 3 As shown, a first heat-conducting layer 3 is connected to the outer surface of the insulating sleeve 2. The first heat-conducting layer 3 is supported by a heat-conducting silicone material. The heat generated by the core wire 1 during operation can be transferred to the outside through the first heat-conducting layer 3, thereby accelerating the heat dissipation speed of the core wire 1.
[0028] like Figure 1 and Figure 3 As shown, the outer surface of the first heat-conducting layer 3 is coaxially connected with a tensile layer 4, and the tensile layer 4 is made of galvanized copper wire. In this way, the tensile layer 4 can increase the tensile strength of the cable, so that the cable will not be easily broken by external force. Moreover, since the tensile layer 4 is made of galvanized copper wire, it also has good thermal conductivity and can transfer the heat on the first heat-conducting layer 3 to the outside.
[0029] like Figure 1 As shown, the outer surface of the tensile layer 4 is provided with a second heat-conducting layer 5, which is made of heat-conducting silicone material. In actual use, the second heat-conducting layer 5 can accelerate the dissipation of heat generated by the core wire 1 during operation and improve the heat dissipation effect.
[0030] The second thermal conductive layer 5 and the tensile layer 4 are connected via an electromagnetic shielding layer 13; the electromagnetic shielding layer 13 is made of aluminum foil material, and can shield electromagnetic signals in the external environment through the electromagnetic shielding layer 13, so that the core wire 1 will not be hindered by electromagnetic signals in the external environment during operation, and the electromagnetic shielding layer 13 also has good thermal conductivity, which can quickly transfer the heat on the tensile layer 4 to the second thermal conductive layer 5, thereby accelerating the heat dissipation speed.
[0031] like Figure 1 and Figure 2 As shown, a plurality of heat-conducting rings 6 are installed on the outer surface of the second heat-conducting layer 5, and a heat-conducting sheet 8 is provided between two adjacent heat-conducting rings 6. The side of the heat-conducting sheet 8 close to the second heat-conducting layer 5 is in contact with the outer surface of the second heat-conducting layer 5. The heat-conducting sheet 8 and the heat-conducting rings 6 can increase the contact area between the second heat-conducting layer 5 and the external environment, thereby improving the heat dissipation speed.
[0032] It should be noted that the heat conducting sheet 8 is spirally arranged and made of heat conducting silicone material, which can increase the length of the heat conducting sheet 8, thereby increasing the contact area between the second heat conducting layer 5 and the external air, and improving the heat dissipation speed.
[0033] It should be noted that if Figure 2 As shown, the outer surface of the second heat-conducting layer 5 is coaxially connected to the thermally conductive silicone sleeve 9, the thermally conductive ring 6 and the thermally conductive sheet 8 are both located in the thermally conductive silicone sleeve 9, and the inner surfaces of the thermally conductive ring 6 and the thermally conductive sheet 8 are in contact with the inner surface of the thermally conductive silicone sleeve 9. During actual use, the thermally conductive silicone sleeve 9 can wrap the thermally conductive ring 6 and the thermally conductive sheet 8. The heat on the thermally conductive ring 6 and the thermally conductive sheet 8 can be transferred to the thermally conductive silicone sleeve 9 and then dissipated into the external environment, and the thermally conductive silicone sleeve 9 will also protect the thermally conductive ring 6 and the thermally conductive sheet 8.
[0034] like Figure 4 As shown, connecting blocks 10 are installed at both ends of the thermal conductive sheet 8, and a limiting block 12 is installed on the side of each thermal conductive ring 6 close to the connecting block 10. The limiting block 12 is a "U"-shaped structure, and one side of the connecting block 10 extends into the interior of the limiting block 12. An adhesive layer 11 is installed on one side of the interior of the limiting block 12. The side of the connecting block 10 is glued together with the inner side of the limiting block 12 through the adhesive layer 11. By fixing the connecting block 10 in the limiting block 12, the two ends of the thermal conductive sheet 8 can be fixed on the thermal conductive ring 6, and the fixation is convenient.
[0035] Specifically, when the present invention is in use, the structural strength of the core wire 1 can be increased by spirally twisting the core wire 1 together, and the provision of the tensile layer 4 can increase the tensile resistance of the cable itself, thereby preventing the cable from being broken or damaged by external force during use. The heat generated by the core wire 1 during operation can be transferred to the first thermal conductive layer 3, and then transferred to the second thermal conductive layer 5 through the first thermal conductive layer 3, the tensile layer 4, and the electromagnetic shielding layer 13, and then transferred to the thermal conductive ring 6 and the thermal conductive sheet 8 through the second thermal conductive layer 5. Finally, the heat is synchronously transferred to the thermal conductive silicone sleeve 9 through the second thermal conductive layer 5, the thermal conductive ring 6 and the thermal conductive sheet 8, and the heat is dissipated to the external environment through the thermal conductive silicone sleeve 9, thereby preventing the core wire 1 from being damaged due to excessive heat accumulation.
[0036] Furthermore, Figure 1 As shown, connecting sleeves 7 are extended on both sides of each heat-conducting ring 6, and the connecting sleeves 7 are all sleeved on the second heat-conducting layer 5. The connecting sleeves 7 can increase the contact area between the heat-conducting ring 6 and the second heat-conducting layer 5, so as to avoid excessive pressure at the connection part between the second heat-conducting layer 5 and the heat-conducting ring 6. When the heat-conducting ring 6 is subjected to force, the second heat-conducting layer 5 and the core wire 1 will not be damaged.
[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
