Description

Technical Field

[0001] The utility model relates to the technical field of enameled wires, in particular to a corrosion-resistant enameled wire. Background Art

[0002] Enameled wire is a main type of winding wire, which consists of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked for many times. However, it is not easy to produce products that meet both standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] In order to improve the power transmission performance of enameled wires, most of the current enameled wires use multi-strand cores and are wrapped with a protective layer. When the enameled wire is subjected to external force, the protective layer is prone to deformation, which can easily cause the multi-strand cores to be misaligned. The local position of the protective layer is prone to remain in a deformed state under the action of the multi-strand core, which can easily keep the protective layer in a stressed state for a long time, thereby increasing the probability of damage to the protective layer. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a corrosion-resistant enameled wire.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: a corrosion-resistant enameled wire, including a wire body, the wire body is provided with three and abuts against each other, a protective layer is installed on the side walls of the three wire bodies, an inner sheath is arranged on the side wall of the protective layer, a steel belt armor layer is arranged on the side wall of the inner sheath, and an outer sheath is arranged on the side wall of the steel belt armor layer.

[0006] By adopting the above technical solution, the armored cable is made of conductors of different materials installed in a metal sleeve with insulating material, and is processed into a bendable solid assembly. Armored cables include armored thermocouples, armored thermal resistors, armored heaters and armored leads, which are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments, and the largest amount is armored thermocouples. Armor is divided into steel strip armor, fine steel wire armor and thick steel wire armor. Steel strip armor enhances the mechanical strength of the enameled wire, thereby reducing the probability of large deformation of the enameled wire when subjected to external force, thereby reducing the probability of the three wire bodies being misaligned with each other, which is conducive to extending the service life of the enameled wire.

[0007] Furthermore, the wire body includes a conductor, a conductor shielding layer arranged on the side wall of the conductor, an insulating layer arranged on the side wall of the conductor shielding layer, an insulating shielding layer arranged on the side wall of the insulating layer, and a copper tape shielding layer arranged on the side wall of the insulating shielding layer.

[0008] Furthermore, the conductor is made of single crystal copper.

[0009] By adopting the above technical solution, single crystal copper is a high-purity oxygen-free copper, and the entire copper rod is composed of only one grain, and there is no "grain boundary" between the grains ("grain boundary" will reflect and refract the passing signal, causing signal distortion and attenuation), so it has extremely high signal transmission performance. Single crystal copper has excellent comprehensive performance because it eliminates the grain boundary as a source of resistance generation and signal attenuation. The conductor made of single crystal copper has excellent electrical and signal transmission performance, good plastic processing performance, excellent corrosion resistance and significant fatigue resistance, which is conducive to improving the transmission efficiency of enameled wire.

[0010] Furthermore, a silver-plated layer is provided on the side wall of the conductor.

[0011] By adopting the above technical solution, the silver-plated copper wire is silver-plated or drawn on high-quality oxygen-free copper, and has excellent electrical conductivity, thermal conductivity, corrosion resistance and high-temperature oxidation resistance. Silver-plated copper wire is widely used in electronics, communications, aerospace, military and other fields. The silver-plated layer reduces the contact resistance of the conductor surface, which is conducive to reducing the loss during the transmission process.

[0012] Furthermore, a filling layer is provided between the protective layer and the wire body.

[0013] By adopting the above technical solution, the filling layer supports the conductor body, thereby improving the stability of the protective layer, and further reducing the probability of misalignment between the three conductor bodies when the protective layer is subjected to external force.

[0014] Furthermore, a ceramic edge layer is provided on the side wall of the copper tape shielding layer.

[0015] By adopting the above technical solution, ceramic insulation material is an excellent insulation material with excellent insulation performance, high temperature resistance and chemical stability, and is widely used in the fields of electricity, electronics, communications, aerospace, etc. The ceramic edge layer made of ceramic insulation material has good high temperature resistance, thereby reducing the probability of failure of the enameled wire, which is conducive to extending the service life of the enameled wire.

[0016] Furthermore, the insulating layer is made of rubber.

[0017] By adopting the above technical solution, the insulating layer is composed of rubber and various compounding agents, and is later heated, vulcanized and finally formed. The insulating layer has good insulating properties, thereby reducing the probability of leakage.

[0018] Furthermore, the outer sheath is made of polyvinyl chloride.

[0019] By adopting the above technical solution, polyvinyl chloride, PVC for short in English, which is the third largest synthetic polymer plastic in the world, has low cost and good wear resistance, which is conducive to reducing the cost of using enameled wire.

[0020] In summary, the utility model has the following beneficial effects:

[0031] Single crystal copper is a high-purity oxygen-free copper. The entire copper rod is composed of only one crystal grain. There is no "grain boundary" between the crystal grains (the "grain boundary" will reflect and refract the passing signal, causing signal distortion and attenuation), so it has extremely high signal transmission performance. Single crystal copper has excellent comprehensive performance because it eliminates the grain boundary as a source of resistance generation and signal attenuation. The conductor 11 made of single crystal copper has excellent electrical and signal transmission performance, good plastic processing performance, excellent corrosion resistance and significant fatigue resistance, which is conducive to improving the transmission efficiency of the enameled wire.

[0032] The protective layer 2 is installed on the side walls of the three conductor bodies 1, and the inner sheath 3 is arranged on the side walls of the protective layer 2. The steel belt armor layer 4 is made of steel belt, and the steel belt armor layer 4 is arranged on the side walls of the inner sheath 3, and the outer sheath 5 is arranged on the side walls of the steel belt armor layer 4.

[0033] The silver-plated layer 6 is disposed on the side wall of the conductor 11. The silver-plated copper wire is formed by silver-plating or drawing high-quality oxygen-free copper, and has excellent electrical conductivity, thermal conductivity, corrosion resistance, and high-temperature oxidation resistance. Silver-plated copper wire is widely used in the fields of electronics, communications, aerospace, and military industry. The silver-plated layer 6 reduces the contact resistance on the surface of the conductor 11, thereby helping to reduce the loss during the transmission process.

[0034] The filling layer 7 is arranged between the protective layer 2 and the wire body 1. The filling layer 7 supports the wire body 1, thereby improving the stability of the protective layer 2 and further reducing the probability of misalignment between the three wire bodies 1 when the protective layer 2 is subjected to external force.

[0035] The ceramic edge layer 8 is made of ceramic insulating material, and the ceramic edge layer 8 is arranged on the side wall of the copper tape shielding layer 15. Ceramic insulating material is an excellent insulating material with excellent insulation performance, high temperature resistance and chemical stability, and is widely used in the fields of electricity, electronics, communications, aerospace, etc. The ceramic edge layer 8 made of ceramic insulating material has good high temperature resistance, thereby reducing the probability of failure of the enameled wire, which is conducive to extending the service life of the enameled wire.

[0036] In order to reduce the probability of leakage, the insulating layer 13 is made of rubber. The insulating layer 13 is made of rubber and various compounding agents, and is heated, vulcanized and finally formed in the later stage. The insulating layer 13 has good insulation performance, thereby reducing the probability of leakage.

[0037] In order to reduce the use cost of the enameled wire, the outer sheath 5 is made of polyvinyl chloride. Polyvinyl chloride, PVC for short, is the third largest synthetic polymer plastic in the world, with low cost and good wear resistance, which is conducive to reducing the use cost of the enameled wire.

[0038] The principle of using a corrosion-resistant enameled wire in this embodiment is as follows: the armored cable is composed of conductors 11 of different materials installed in a metal sleeve of insulating material, and is processed into a bendable solid assembly. The armored cable includes armored thermocouples, armored thermal resistors, armored heaters and armored leads, which are mainly used for temperature measurement, signal transmission and special heating in chemical industry, metallurgy, machinery manufacturing, power generation and scientific experiments, and the largest amount is armored thermocouples. The armor is divided into steel strip armor, fine steel wire armor and thick steel wire armor. The steel strip armor enhances the mechanical strength of the enameled wire, thereby reducing the probability of large deformation of the enameled wire when subjected to external force, thereby reducing the probability of mutual dislocation of the three wire bodies 1, which is beneficial to prolonging the service life of the enameled wire.
