AI Technical Summary
The existing power supply line production process is complex and has a thick thickness, resulting in poor flexibility and it is difficult to maintain electrical transmission characteristics in the embossing process.
The insulating outer design is adopted, including the inner edge, the outer edge and the embossed part, with a thickness of 0.39mm to 1.5mm. In line with the setting of the embossed part, the thickness of the insulating outer layer is reduced to maintain the strength and flexibility of the power line, and complies with UL safety regulations.
When the thickness is reduced in the embossing process, the power cord still has better strength and flexibility, maintains electrical transmission characteristics, and meets the requirements of UL safety regulations.

[0029] The power cord of the embodiment of the present utility model will be further described below in conjunction with the accompanying drawings.
[0030] The foregoing and other technical contents, features and effects of the invention will be clearly presented in the following detailed description of the preferred embodiments with reference to the drawings. It is worth mentioning that the directional terms mentioned in the following embodiments, such as up, down, left, right, front or back, etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for illustration, rather than limiting the invention. In addition, in the following embodiments, the same or similar components will be denoted by the same or similar reference numerals.
[0031] Please refer to Figures 1 to 5, as shown in the figure: The present utility model provides a power cord 1, which at least includes a core wire 11 and an insulating jacket 12.
[0032] The insulating jacket 12 covers the outside of the core wire 11. The insulating jacket 12 includes an inner edge portion 121, an outer edge portion 122, and an embossed portion 123. The inner edge portion 121 is provided on the inner side of the insulating jacket 12 and contacts the core wire 11. The outer edge portion 122 is provided on the outer side of the insulating jacket 12. The embossed portion 123 is provided on the outer edge portion 122, and the thickness h from the inner edge portion 121 to the outer edge portion 122 of the insulating jacket 12 is 0.39 mm to 1.5 mm.
[0033] In this way, by using the thickness h from the inner edge portion 121 to the outer edge portion 122 of the insulating jacket 12 being 0.39 mm to 1.5 mm, and at the same time cooperating with the setting of the embossed portion 123, when the power cord 1 is in the embossing process, even if the thickness h of the insulating jacket 12 is reduced, the power cord 1 can still have better strength and flexibility through the setting of the embossed portion 123, and can meet the requirements of UL safety regulations. Furthermore, the electrical transmission characteristics of the power cord 1 can be effectively maintained to avoid affecting the electrical transmission characteristics of the power cord 1 during use due to the omission of the braided layer.
[0034] In addition to the above embodiments, in an embodiment of the present utility model, the difference from the above embodiments is that the core wire 11 can be a stranded wire or a coaxial cable. In this way, the required core wire 11 can be selected according to different usage requirements, so that the power cord 1 has better electrical transmission characteristics during use.
[0035] In addition to the above embodiments, in an embodiment of the present utility model, the difference from the above embodiments is that the insulating jacket 12 can be at least made of materials such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), or thermoplastic elastomer (TPE) as required. In this way, with the cooperation of the material characteristics of the insulating jacket 12 and the thickness h of 0.39 mm to 1.5 mm, when the power cord 1 is in the embossing process, even if the thickness h of the insulating jacket 12 is reduced, the power cord 1 can still have better strength and flexibility through the setting of the embossed portion 123, and can meet the requirements of UL safety regulations. Furthermore, the electrical transmission characteristics of the power cord 1 can be effectively maintained to avoid affecting the electrical transmission characteristics of the power cord 1 during use due to the omission of the braided layer.
[0036] In addition to the above embodiments, in an embodiment of the present invention, the difference from the above embodiments lies in that the embossing portion 123 may be a single groove 1231, multiple grooves 1231, or a combination thereof, and the embossing portion 123 can be formed into multiple rectangular bodies 1232 (as Figure 1 shown), multiple polygon bodies 1233 (as Figure 3 shown), multiple arc bodies 1234 (as Figure 4 shown), or multiple scale bodies 1235 (as Figure 5 shown) by using a single groove, multiple grooves, or a combination thereof. In this way, the embossing portion 123 can present different types of the insulating jacket 12 through each rectangular body 1232, each polygon body 1233, each arc body 1234, and each scale body 1235. And different types of the insulating jacket 12 can all make the power cord 1 have the thickness h of the insulating jacket 12 in the range of 0.39 mm to 1.5 mm. At the same time, with the setting of the embossing portion 123, when the power cord 1 is in the embossing process, even if the thickness h of the insulating jacket 12 is reduced, the power cord 1 can still have better strength and flexibility through the setting of the embossing portion 123, and can meet the requirements of UL safety regulations. Furthermore, the electrical transmission characteristics of the power cord 1 can be effectively maintained to avoid affecting the electrical transmission characteristics of the power cord 1 during use due to the omission of the braided layer.
[0037] In summary, the power cord provided by the embodiment of the present invention can still have better strength and flexibility when the thickness is reduced during the embossing process, and can meet the requirements of UL safety regulations to maintain the electrical transmission characteristics of the power cord.
[0038] The above are only the embodiments of the present invention, and they are not intended to limit the patent scope of the present invention.
