Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical wiring technology, specifically a low-loss, anti-interference electrical wiring. Background Technology
[0002] The existing announcement number CN214796791U discloses a smart home green and environmentally friendly double-layer insulated flame-retardant and anti-interference wire, including a protective sleeve. A composite layer is fixed to the inner circumference of the protective sleeve, a first insulation layer is fixed to the inner circumference of the composite layer, and a glass fiber thermally conductive layer is fixed to the inner circumference of the first insulation layer. Orderly arranged wire cores are arranged inside the glass fiber thermally conductive layer. The composite layer includes a first flame-retardant layer sleeved outside the first insulation layer, a shielding layer sleeved outside the first flame-retardant layer, a second flame-retardant layer sleeved outside the shielding layer, and a second insulation layer sleeved outside the second flame-retardant layer and in contact with the inner circumference of the protective sleeve. This design achieves rapid heat dissipation, while the braided layer prevents dust ingress, resulting in good insulation, strong anti-interference ability, and good flame retardancy.
[0003] While existing fabric cables have a certain degree of anti-interference capability, their tensile strength is generally limited. Therefore, we propose a low-loss anti-interference fabric cable. Utility Model Content
[0004] The purpose of this invention is to provide a low-loss, anti-interference power supply to solve the problems in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a low-loss, anti-interference power supply wire, comprising two parallel conductors, the two conductors being co-extruded and covered by a first insulating layer, the upper and lower sides of the first insulating layer being concave structures, an anti-tension rope being provided at the concave structure of the first insulating layer, the anti-tension rope and the first insulating layer being covered by a first shielding layer, a second shielding layer being covered on the outside of the first shielding layer, and a second insulating layer being covered on the outside of the second shielding layer.
[0006] Preferably, the first shielding layer is an aluminum foil layer, and the second shielding layer is a copper wire braided layer.
[0007] Preferably, the first insulating layer is a solid insulating layer or a foamed insulating plastic layer, and the second insulating layer is a solid insulating layer or a foamed insulating plastic layer.
[0008] Preferably, the conductor is a high-purity copper conductor or a silver-plated copper core.
[0009] Preferably, the tensile rope is made of tensile fiber rope or steel wire rope.
[0010] Compared with the prior art, the beneficial effects of this utility model are: By directly bearing the tensile force through the anti-tension rope and combining it with high-strength anti-tension rope material, the overall tensile strength of the cable is significantly improved, avoiding line damage caused by external stretching, extending service life, and adapting to more scenarios that require stretching and laying.
[0011] The conductor is made of high-purity material to reduce resistance loss, and the insulation layer is made of low dielectric loss material to reduce dielectric loss. The two links work together to control transmission loss, so that high efficiency can be maintained for both power transmission and signal transmission, avoiding energy waste or excessive signal attenuation.
[0012] The double-layer shielding structure (aluminum foil + copper wire braid) is designed for low and high frequency interference scenarios, with a wide shielding coverage. It can effectively block external electromagnetic interference (such as power frequency interference, radio frequency interference, etc.) and ensure that the electrical energy or signal transmitted inside the conductor is not interfered with.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.
[0016] Please see Figure 1In this embodiment of the present invention, a low-loss anti-interference building wire includes two parallel conductors 1. The two conductors 1 are co-extruded and covered by a first insulating layer 3. The upper and lower sides of the first insulating layer 3 are both concave structures. An anti-tension rope 2 is provided in the concave structure of the first insulating layer 3. The anti-tension rope directly bears the tensile force. Combined with the high-strength anti-tension rope material, the overall tensile strength of the building wire is significantly improved, avoiding line damage caused by external stretching, extending service life, and adapting to more scenarios that require stretching and laying. The anti-tension rope 2 and the first insulating layer 3 are covered by a first shielding layer 4. A second shielding layer 5 is covered on the outside of the first shielding layer 4, and a second insulating layer 6 is covered on the outside of the second shielding layer 5.
[0017] The conductor 1 is made of high-purity copper conductor or silver-plated copper core; the tensile rope 2 is made of tensile fiber rope or steel wire rope; the first shielding layer 4 is made of aluminum foil layer, and the second shielding layer 5 is made of copper wire braided layer. The aluminum foil can effectively block low-frequency interference, while the braided mesh is designed to block high-frequency radio frequency interference; the first insulation layer 3 is made of solid insulation layer or foamed insulating plastic layer, and the second insulation layer 6 is made of solid insulation layer or foamed insulating plastic layer.
[0018] The working principle of this utility model is as follows: the conductor is made of high-purity copper or aluminum conductor, which has excellent conductivity and can effectively reduce DC resistance and reduce Joule heat loss during current transmission; at the same time, the high-purity material can reduce the obstruction of current by impurities, further reduce signal attenuation during signal transmission, and ensure low-loss transmission of electrical energy or signals.
[0019] Both the first and second insulating layers can be either solid insulating layers or foamed insulating plastic layers. Both types of insulating materials have the characteristics of low dielectric constant and low dielectric loss tangent, which can significantly reduce the energy loss of signals caused by dielectric polarization in the insulating layer (i.e., dielectric loss), while avoiding leakage between the conductor and the external structure. While achieving electrical insulation, they further maintain the low loss characteristics of transmission.
[0020] The system employs a double-layer shielding structure consisting of an aluminum foil layer (first shielding layer) and a copper wire braided layer (second shielding layer). These two layers work together to achieve interference resistance: the inner aluminum foil layer provides excellent low-frequency shielding, effectively preventing external low-frequency interference signals (such as 50Hz power frequency interference) from penetrating the shielding layer and affecting conductor transmission; the outer copper wire braided layer offers stronger shielding against high-frequency interference signals (such as radio frequency signals), intercepting high-frequency interference and releasing it through grounding to prevent it from entering the conductor and interfering with signal or power transmission. This double-layer shielding structure covers both low- and high-frequency interference scenarios, forming a comprehensive electromagnetic shielding barrier and significantly improving interference resistance.
[0021] The first insulation layer is designed with concave structures on both the top and bottom sides. The tension rope (tension fiber rope or steel wire rope) is embedded in the concave areas and is completely covered and fixed by the first shielding layer. This layout allows the tension rope to directly bear the tensile force on the wire during laying and use, avoiding the tensile force from acting directly on the conductor or insulation layer. At the same time, the tension rope material itself has high tensile strength, which can disperse and bear external forces, preventing the wire from breaking due to tension and damaging the insulation layer, thus ensuring structural integrity and transmission stability.
[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
