[0018] The present application is further described in detail below in conjunction with the accompanying drawings.

[0019] In order to more clearly understand the technical solution provided by the embodiment of the present application, the working state of the existing power cord is first briefly introduced.

[0020] The power cord mainly plays the role of conducting current and has a low resistance. When the power of the appliance is too large, the current passing through the power cord increases. Although the resistance of the wire to the current is low, it does not mean zero resistance. The significantly increased current passes through the wire, causing the wire to heat up. In the prior art, the outside of the wire is wrapped with several insulating layers, and there are certain gaps containing air between the insulating layers. This causes the heat generated by the wire in the power cord to accumulate in the insulating layer outside the wire, causing overheating, which can easily damage the power cord.

[0021] In order to solve the above technical problems, the present application embodiment provides an improved high temperature resistant and anti-oxidation power cord, referring to Figure 1 , including an insulating jacket 11 and a plurality of wires 12 arranged inside the insulating jacket 11, an insulating layer is arranged on the outside of the wires 12, a flexible heat-conducting pipe 13 is arranged inside the insulating jacket 11, and the plurality of wires 12 are arranged inside the flexible heat-conducting pipe 13, and the inner side of the flexible heat-conducting pipe 13 is in close contact with the outer side of the insulating layer of the wires 12.

[0022] The following is a further introduction based on specific usage scenarios.

[0023] When a large current passes through the power cord, the impedance of the wire 12 to the current will cause the current to be converted into heat energy and form loss. In the embodiment of the present application, the inner side of the flexible heat pipe 13 is in close contact with the outer side of the insulation layer of the wire 12, so that the heat generated by the wire 12 can be absorbed by the flexible heat pipe 13 and quickly transferred to the insulating jacket 11. The insulating jacket 11 is in contact with the outside air to quickly dissipate the heat into the surrounding air, thereby reducing the amount of heat accumulated inside the power cord and reducing the probability of overheating of the power cord. At the same time, on the basis of reducing the overheating of the power cord, the probability of rapid oxidation of the power cord due to overheating of the power cord is also reduced.

[0024] In general, the embodiment of the present application is to set a flexible heat-conducting tube 13 that can quickly conduct heat between the insulating jacket 11 of the power cord and the conductor 12, so that the heat generated by the conductor 12 can be quickly discharged, reducing the amount of heat accumulated between the conductor 12 and the insulating jacket 11, and significantly reducing the probability of overheating of the power cord.

[0025] In the embodiment of the present application, the inner side of the flexible heat pipe 13 is in close contact with the outer side of the insulation layer of the wire 12 , which reduces the amount of air outside the wire 12 , so that the heat of the wire 12 can be quickly transferred away by the flexible heat pipe 13 .

[0026] As a feasible specific implementation method of the present application embodiment, refer to Figure 2 A heat-conducting separator 14 is also provided on the inner side of the flexible heat-conducting pipe 13 , and the plurality of wires 12 are separated by the heat-conducting separator 14 , so that the plurality of wires 12 are independent of each other, and the outer side of the insulation layer of the wire 12 is in close contact with the inner side of the flexible heat-conducting pipe 13 and the heat-conducting separator 14 .

[0027] The plurality of wires 12 are separated by a heat-conducting separator 14, so that the plurality of wires 12 are independent of each other and do not touch each other inside the insulating jacket 11. In this way, when the heat generated by the wires 12 is dissipated to the surroundings, the heat-conducting separator 14 and the flexible heat-conducting tube 13 can quickly transfer the heat generated by the wires 12 to avoid heat accumulation between the wires 12 and causing overheating of the power cord, further improving the heat dissipation efficiency of the power cord and reducing the probability of overheating of the power cord.

[0028] In some possible implementations of the present application, a heat conductive wire 15 is disposed in the middle of the heat conductive separator 14, and the heat conductive wire 15 runs through the heat conductive separator 14. The heat conductive wire 15 is disposed to further improve the heat dissipation efficiency of the power cord and reduce the probability of overheating of the power cord.

[0029] In some possible implementations of the embodiments of the present application, the flexible heat-conducting pipe 13 and the heat-conducting separator 14 are both made of heat-conducting glue.

[0030] As a feasible specific implementation method of the present application embodiment, refer to Figure 3 A heat-conducting film 16 is fixedly connected to the inner wall of the flexible heat-conducting pipe 13 , and the inner side of the heat-conducting film 16 is in close contact with the outer side of the flexible heat-conducting pipe 13 . The heat-conducting film 16 is made of aluminum foil.

[0031] After the flexible heat pipe 13 absorbs the heat of the wire 12, the heat conductive film 16 can quickly and evenly transfer the heat to the insulating jacket 11, further improving the heat dissipation efficiency of the power cord and reducing the probability of overheating of the power cord.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
