Description

Technical Field

[0001] This utility model relates to the field of power cord technology, and more specifically, to a high-temperature resistant power cord with good insulation performance. Background Technology

[0002] Household power cords are generally exposed to the elements and, over time, inevitably suffer from pulling and even chewing by rodents. Chewing damages the cord, making it unsafe to use and rendering it unusable. For example, patent CN218414010U discloses a high-temperature resistant power cord. Its first protective layer includes an outer high-temperature resistant layer, a corrosion-resistant layer, a fire-resistant layer, and a sound-insulating layer. The outer high-temperature resistant layer is fixedly disposed on the outer surface of the corrosion-resistant layer. The inner surface of the corrosion-resistant layer is fixedly connected to the outer surface of the fire-resistant layer, and the inner surface of the fire-resistant layer is fixedly connected to the outer surface of the sound-insulating layer. The inner side of the sound-insulating layer is wrapped around the outer side of the inner high-temperature resistant layer. The corrosion-resistant layer is made of fiberglass, improving the cord's corrosion resistance. The fire-resistant layer is made of polyester fiber, improving its fire-retardant properties. The sound-insulating layer is made of polyester fiber, improving its sound insulation and noise reduction performance.

[0003] When the above-mentioned device is in use, the outer insulation layer makes the outer surface of the power cord insulated, the wear-resistant layer makes the outer surface of the power cord wear-resistant, and the reinforcing layer greatly improves the internal strength of the power cord, which can prevent the power cord from breaking when it is chewed by rats or pulled by external forces. However, the power cord is prone to generating heat during use, and the bending process of the power cord can cause damage and cracking to its internal structure, thereby affecting the service life and stability of the power cord.

[0026] This utility model provides a high-temperature resistant power cord with good insulation performance, such as... Figure 1 , 2 As shown in Figures 3 and 4, the power cord includes a main body 1 with a metal conductor 2 in the middle of its inner end face. Current is transmitted through the metal conductor 2. An insulating jacket 10 is provided at the upper end of the outer end face of the metal conductor 2. The insulating jacket 10 is a composite of mica powder and organosilicon resin or organosilicon-boron resin, which can be converted into a ceramic material at high temperature. It can maintain an insulating state even in a fire, thereby effectively increasing the insulation effect of the power cord. An insulating jacket 9 is provided on the outer end face of the insulating jacket 10. The insulating jacket 9 is made of alkali-free glass fiber interwoven and wrapped, which has strong flexibility, high tensile strength, high elastic coefficient, good rigidity, and also has strong electrical insulation performance.

[0027] The outer end face of the insulating jacket 9 is provided with a filler layer 3. The filler layer 3 is a semi-crystalline thermoplastic polymer made by addition polymerization of propylene monomers. It is usually a white waxy solid with good insulation properties, heat resistance, and corrosion resistance. The outer end face of the filler layer 3 is provided with an insulating adhesive tape 6. The outer end face of the insulating adhesive tape 6 is provided with a separating tape 7. The outer end face of the separating tape 7 is provided with a reinforcing strap 8. The outer end face of the reinforcing strap 8 is provided with a connecting adhesive layer 5.

[0028] The outer end face of the connecting adhesive layer 5 is provided with an electrical wire surface layer 4. The diameter of the metal wire 2 in the right-view direction is 2mm, the diameter of the insulating jacket 10 in the right-view direction is 0.2mm, the diameter of the insulating jacket 9 in the right-view direction is 0.5mm, and the diameter of the filling layer 3 in the right-view direction is 4mm.

[0030] Processed at high temperature, the insulating jacket 9 is made of alkali-free glass fiber interwoven and wrapped, the filling layer 3 is a polypropylene component, and the insulating adhesive tape 6 and reinforcing strap 8 are both PET components. PET has high strength and heat resistance, as well as low permeability, which prevents the penetration of gas and water vapor, and has excellent gas barrier, water barrier, oil barrier and odor barrier properties. The insulating adhesive tape 6 and reinforcing strap 8 are both arranged in a spiral state.

[0031] The insulating adhesive tape 6 and the reinforcing binding tape 8 are arranged in a mirror image in the spiral direction of the main view, which can effectively increase the structural strength of the power cord. The connecting adhesive layer 5 is a polyethylene component, and the wire surface layer 4 is a cross-linked polyethylene component. The cross-linked modified polyethylene can significantly improve its performance, not only significantly improving the comprehensive performance of polyethylene such as mechanical properties, environmental stress cracking resistance, chemical corrosion resistance, creep resistance and electrical properties, but also significantly improving the temperature resistance of the power cord. The outer end face of the wire surface layer 4 is provided with an anti-oxidation layer 11, and the outer end face of the anti-oxidation layer 11 is provided with a wear-resistant layer 12. The anti-oxidation layer 11 and the wear-resistant layer 12 can prevent the wire surface layer 4 from oxidation and wear caused by the external environment, thereby increasing the service life of the power cord body 1.
