Description
Technical Field
[0001] This utility model belongs to the field of circular winding wire technology, specifically relating to a general-purpose enamel-reinforced copper-clad aluminum circular winding wire. Background Technology
[0002] Winding wires are round windings made of copper and aluminum. Generally, the winding coils in electric motors are made of round-core copper or aluminum wire, but high-power motors use flat copper or aluminum strips. Applications: Electric motor winding connections are divided into two types: primacy and common pole. Based on the wiring method, they are divided into centralized and distributed types. Distributed wiring is further divided into concentric and lapped types. Lapd types include single-lap, double-lap, single / double-winding crossover, and single / double-layer hybrid types.
[0003] The existing technology has the following problems:
[0004] 1. Currently available copper-clad aluminum round winding wires on the market have poor toughness, poor heat resistance, and poor internal insulation, making the wires prone to damage during use;
[0005] 2. Currently available copper-clad aluminum round winding wires are not convenient for replacing circuits or improving circuit stability. Utility Model Content
[0006] The purpose of this invention is to provide a universal enamel-reinforced copper-clad aluminum round winding wire for existing devices, in order to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a general-purpose copper-clad aluminum round winding wire with enamel film reinforcement, comprising a wire core and a flame-retardant coating, wherein a polyvinyl chloride protective layer is provided on the outer wall of the wire core, four outer conductors are provided inside the flame-retardant coating, an electromagnetic shielding enamel layer is provided on the outer side of the outer conductors, and a thermal insulation filler is provided inside the flame-retardant coating.
[0008] The outer wall of the flame-retardant coating is wrapped with an insulating sleeve, and the outer wall of the insulating sleeve is wrapped with an outer wear-resistant layer.
[0009] The present invention further explains that the outer wear-resistant layer is woven from nylon filaments, and the outer wall of the outer wear-resistant layer is provided with a corrosion-resistant coating, which is connected between the outer wear-resistant layer and the insulating sleeve.
[0010] The above technical solution uses an outer wear-resistant layer made of nylon filaments, which provides wear resistance and water resistance. The corrosion-resistant coating effectively prevents corrosion of the outermost layer during long-term use, thus reducing the safety factor and service life and improving the practicality and convenience of the device.
[0011] The present invention further explains that a locking groove is provided on one side surface of the insulating sleeve, and the number of locking grooves is multiple and the multiple locking grooves are equally spaced around the surface of the insulating sleeve.
[0012] By adopting the above technical solution, the insulation material of the insulating sleeve can achieve properties such as low loss, high temperature resistance, and ultra-high voltage resistance.
[0013] The present invention further explains that the outer wall of the insulating sleeve is fixedly connected with a locking block, and the locking block is multiple and the multiple locking blocks are equally spaced and arranged around the outer wall of the insulating sleeve.
[0014] By adopting the above technical solution, the setting of several locking blocks not only improves the stability of the wire core, but also allows the wire core to be stripped and replaced when a problem occurs.
[0015] The present invention further explains that a spring is fixedly connected to the outer wall of the locking block, and the locking block is engaged with the locking groove through the spring.
[0016] By adopting the above technical solution, the locking block engages with the inside of the locking groove, and the spring generates pressure to press the inside of the locking groove. The spring prevents loosening between the locking blocks, making them unable to separate and allowing for reuse. This effectively reduces replacement costs and improves the practicality of the device.
[0017] This invention further illustrates that reflective strips are adhered to the outer surface of the corrosion-resistant coating.
[0018] By adopting the above technical solution, the reflective strips can reflect light, reducing the rapid temperature rise of the wiring harness caused by prolonged exposure to light.
[0019] Compared with the prior art, the beneficial effects achieved by this utility model are:
[0020] This utility model provides a general-purpose copper-clad aluminum round winding wire reinforced with enamel film. The glass fiber mesh in the PVC protective layer, due to its weak tensile strength, bears most of the tensile force, thus ensuring the usability of the internal core. The insulation filler has excellent thermal insulation properties, preventing external cold from penetrating its interior and effectively protecting the plastic insulation sheath of the core from embrittlement. A flame-retardant coating enhances its safety. The insulation material of the insulating sleeve achieves low loss, high temperature resistance, and ultra-high voltage resistance. The outer wear-resistant layer is made of nylon filament braid, providing wear resistance and waterproofing. The corrosion-resistant coating effectively prevents corrosion of the outermost layer during long-term use, strengthening its overall performance, increasing tensile strength, and significantly extending the service life of the wire, thus meeting the user's needs.
[0021] This utility model provides a universal copper-clad aluminum round winding wire reinforced with enamel film. Through the cooperation of locking blocks, springs, and locking grooves, and by setting several locking blocks, not only can the stability of the wire core be improved, but it can also be peeled off and replaced when the wire core has a problem. It also facilitates the splicing of multiple wire segments to achieve the effect of length extension. The locking blocks are locked into the locking groove, and the spring generates pressure to press the locking groove inward. The spring prevents loosening between the locking blocks and prevents them from separating, allowing for reuse. This effectively reduces replacement costs and improves the practicality of the device, meeting the user's needs. Attached Figure Description

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0030] Please see Figure 1-5The present invention provides a technical solution: a general-purpose copper-clad aluminum round winding wire with a coating film reinforcement, comprising a wire core 1 and a flame-retardant coating 6. The outer wall of the wire core 1 is provided with a polyvinyl chloride protective layer 2. The flame-retardant coating 6 is provided with four outer conductors 3. The outer side of the outer conductors 3 is provided with an electromagnetic shielding coating layer 4. The flame-retardant coating 6 is filled with a thermal insulation filler 5.
[0031] The outer wall of the flame-retardant coating 6 is wrapped with an insulating sleeve 7, and the outer wall of the insulating sleeve 7 is wrapped with an outer wear-resistant layer 8.
[0032] In this embodiment, the fiberglass mesh in the PVC protective layer 2, due to its weak tensile strength, bears most of the tensile force, thus ensuring the usability of the internal core 1. The thermal insulation filler 5 has good thermal insulation properties, preventing external cold from penetrating its interior and effectively protecting the plastic insulation sheath of the core 1 from embrittlement. The flame-retardant coating 6 enhances its safety. The insulation material of the insulating sleeve 7 achieves low loss, high temperature resistance, and ultra-high voltage resistance. The outer wear-resistant layer 8 is woven from nylon filaments, providing wear resistance and waterproofing. The corrosion-resistant coating 9 effectively prevents corrosion of the outermost layer during long-term use, thus preventing a decrease in safety factor and service life, enhancing its overall performance, improving tensile strength, and greatly extending the service life of the wiring harness. This makes the wiring harness more widely applicable and worthy of promotion.
[0033] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the outer wear-resistant layer 8 is woven from nylon filaments, the outer wall of the outer wear-resistant layer 8 is provided with a corrosion-resistant coating 9, and the corrosion-resistant coating 9 is connected between the outer wear-resistant layer 8 and the insulating sleeve 7. A locking groove 10 is opened on one side surface of the insulating sleeve 7, and the number of locking grooves 10 is multiple and the multiple locking grooves 10 are equally spaced and arranged around the surface of the insulating sleeve 7. A locking block 11 is fixedly connected to the outer wall of the insulating sleeve 7, and the number of locking blocks 11 is multiple and the multiple locking blocks 11 are equally spaced and arranged around the outer wall of the insulating sleeve 7.
[0034] In this embodiment, the outer wear-resistant layer 8 is made of nylon filament braid, which has the advantages of wear resistance and water resistance. The corrosion-resistant coating 9 can effectively prevent corrosion of the outermost layer during long-term use of the device, which would reduce the safety factor and service life, thus improving the practicality and convenience of the device. The insulation material of the insulating sleeve 7 can achieve performance such as low loss, high temperature resistance and ultra-high voltage resistance. By setting several locking blocks 11, not only can the stability of the wire core 1 be improved, but it can also be peeled off and replaced if the wire core 1 has a problem.
[0035] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a spring 12 is fixedly connected to the outer wall of the locking block 11, the locking block 11 is locked to the locking groove 10 through the spring 12, and a reflective strip 13 is adhered to the outer surface of the corrosion-resistant coating 9.
[0036] In this embodiment, the locking block 11 is locked into the locking groove 10, and the spring 12 generates pressure to press the locking groove 10 into the interior. The spring 12 prevents loosening between the locking and locking parts, and the device can be reused, which effectively reduces the replacement cost and improves the practicality of the device. The reflective strip 13 can reflect light, reducing the rapid temperature rise of the wiring harness caused by prolonged light exposure.
[0037] like Figure 1-5 As shown, when the user needs to use it, the fiberglass mesh in the PVC protective layer 2, due to its weak tensile strength, will bear most of the tensile force, thus ensuring the use of the internal core 1. The thermal insulation filler 5 has good thermal insulation properties, preventing external cold from penetrating its interior and effectively protecting the plastic insulation outer sheath of the core 1 from embrittlement. The flame-retardant coating 6 enhances its safety. The insulation material of the insulating sleeve 7 achieves low loss, high temperature resistance, and ultra-high voltage resistance. The outer wear-resistant layer 8 is made of nylon filament braid, providing wear resistance and waterproofing. The corrosion-resistant coating 9 effectively prevents corrosion of the outermost layer during long-term use. The corrosion is reduced, which enhances the overall performance during use, improves tensile strength, and greatly extends the service life of the wire assembly. Through the cooperation between the locking block 11, spring 12, and locking groove 10, by setting several locking blocks 11, not only can the stability of the wire core 1 be improved, but it can also be peeled off and replaced after the wire core 1 has a problem. It is also convenient to splice the length of multiple wire assemblies to achieve the effect of extension. The locking block 11 is locked into the inside of the locking groove 10, and the spring 12 generates pressure to press the locking groove 10 into the inside. The spring 12 prevents loosening between the locking blocks and prevents them from separating, so that they can be reused. This effectively reduces the replacement cost and improves the practicality of the device.
