Description

Technical Field

[0001] This utility model relates to the field of LED power supply line technology, and in particular to a high-strength flame-retardant thin-walled double parallel conductor for LEDs. Background Technology

[0002] LED is a commonly used light-emitting device that releases light by recombination of electrons and holes. It is widely used in the lighting field. LEDs can efficiently convert electrical energy into light energy and have a wide range of applications in modern society, such as lighting and flat panel displays. LED lights are generally powered by wires, and double parallel wires are widely used in LED power supply circuits due to their strong anti-interference ability and good conductivity.

[0003] Existing LED power supply double parallel wires have the following drawbacks during use: the outer perimeter of LED double parallel wires is generally covered with plastic or rubber, resulting in a large overall wall thickness. LED lights, especially detachable stage LED lights, need to be frequently changed in installation position according to different installation requirements, which causes the wire to be frequently bent and adjusted, easily leading to wire wear. To address this, we propose a high-strength flame-retardant thin-walled double parallel wire specifically for LEDs. Utility Model Content

[0004] The main purpose of this utility model is to provide a high-strength flame-retardant thin-walled double-parallel conductor for LEDs. By improving the double-parallel conductor, its overall strength and flame retardancy are improved, while the wall thickness is effectively reduced, making it easier to install. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-strength flame-retardant thin-walled double-parallel conductor for LEDs includes a double-parallel conductor, which is composed of a core, an insulation layer, a shielding layer, a flame-retardant layer, and an outer sheath. The core is surrounded by an insulation layer, and the insulation layer is surrounded by a shielding layer. The shielding layer is surrounded by a flame-retardant layer, and the flame-retardant layer is surrounded by an outer sheath. The double-parallel conductor is wrapped with protective tape A and protective tape B, which are alternately wrapped around the outer periphery of the double-parallel conductor.

[0007] Furthermore, the insulation layer is made of polyvinyl chloride, and the shielding layer is made of metal braided mesh. Polyvinyl chloride insulation layer has the characteristics of low cost, good rigidity and good insulation. Metal braided mesh, as a shielding layer, has a good shielding effect against electromagnetic interference and reduces interference between parallel conductors.

[0008] Furthermore, the flame-retardant layer is made of polytetrafluoroethylene (PTFE), and the outer sheath is made of polyethylene. The flame-retardant layer made of PTFE has excellent thermal stability, mechanical wear resistance, and electrical insulation properties. It is corrosion-resistant, fire-resistant, non-combustible, low-smoke, and halogen-free, which can improve the flame-retardant characteristics of the conductor. The outer sheath is made of polyethylene, which not only has good electrical performance but also has water resistance, moisture resistance, and good environmental adaptability.

[0009] Furthermore, the protective tape A is made of polyester braided tape, and the protective tape B is made of aramid filament; the outer periphery of the double-parallel conductor is equipped with alternating braided protective tapes A and B to ensure the protective effect while reducing the overall wall thickness of the conductor.

[0010] Compared with the prior art, this utility model has the following beneficial effects: The double-parallel conductor has a flame-retardant layer inside, which is made of polytetrafluoroethylene. The flame-retardant layer has excellent thermal stability, mechanical wear resistance, electrical insulation properties, corrosion resistance, fire resistance, non-combustibility, low smoke, and halogen-free properties, which can improve the flame-retardant characteristics of the conductor. The protective tape A is made of polyester braided tape, which has good shrinkage and toughness, smooth and flat surface, high strength, and high temperature resistance. The protective tape B is made of aramid filament, which has high strength and excellent flame-retardant properties. The alternating braided protective tapes A and B are used on the outer periphery of the double-parallel conductor to ensure the overall strength and flame retardancy of the conductor while reducing the overall wall thickness of the conductor, which is convenient for laying and installation. It is especially suitable for LED conductors and can meet the requirements of multiple bending and laying and protection standards. Attached Figure Description
