Description

Technical Field

[0001] This utility model relates to the field of copper braided wire technology, and in particular to a fracture-resistant and high-temperature-resistant copper braided wire. Background Technology

[0002] Copper braided wire flexible connectors are mainly used in transformer installations, high and low voltage switchgear, vacuum electrical appliances, enclosed busbars, generators and busbars, rectifier equipment, rectifier cabinets and disconnect switches, automotive batteries, electric locomotives, industrial electric scooters, mining explosion-proof electrical equipment, generator sets, flexible connections for carbon brush wires, and connections between busbars.

[0003] However, copper braided wire is often subjected to bending forces during use, and repeated bending and deformation can easily cause the copper wires in the core to break, resulting in the copper braided wire being unable to conduct electricity, shortening its service life, and generating more heat during operation, which can easily cause deformation.

[0004] Therefore, it is necessary to provide a fracture-resistant, high-temperature-resistant copper braided wire to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a fracture-resistant and high-temperature-resistant copper braided wire to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fracture-resistant and high-temperature-resistant copper braided wire, comprising an inner core main wire group and a secondary wire braiding group, wherein the secondary wire braiding group covers the inner core main wire group. The inner core main wire group comprises a main core and a covering layer. The main core is composed of copper wire and steel wire, and multiple steel wires are arranged therein. These multiple steel wires are evenly wound and twisted around the outer circumference of the copper wire. The covering layer is disposed outside the main core. A first adhesive layer is disposed outside the outer circumference of the copper wire. A second adhesive layer is disposed outside the first adhesive layer. A third adhesive layer is disposed outside the second adhesive layer. The secondary wire braiding group comprises multiple secondary wires, which are cross-braided using a crisscross pattern.

[0007] In a preferred embodiment of this invention, the diameter of the steel wire is smaller than that of the copper wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention discloses a fracture-resistant, high-temperature resistant copper braided wire. Six steel wires are evenly wound and twisted around the outer circumference of the copper wire, improving the bending and tensile strength of the core. When the core is subjected to tensile and bending forces, the steel wires protect the copper wire, preventing excessive tensile deformation and ensuring it does not break when bent. A polytetrafluoroethylene (PTFE) layer, a polytetrafluoroethylene (PTFE) layer, and a corrosion-resistant rubber layer are sequentially arranged on the outer circumference of the copper wire. This composite structure significantly improves the high-temperature resistance of the copper wire. Inorganic acid and... The organic acid compound cleaning agent cleans the surface of the secondary wire, removes impurities, and forms a uniform, dense, and difficult-to-remove protective film on the surface, improving the secondary wire's anti-oxidation and high-temperature resistance, and extending its service life. The cross-braiding method used to cross-braid the secondary wire to form a stranded structure improves the bending toughness of the secondary wire braid, thereby improving the tensile and bending resistance of the copper braided wire. This effectively prevents the copper braided wire from undergoing large deformation and breakage under tension and bending forces, greatly extending the service life of the copper braided wire.

[0022] The embodiments of this utility model will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0023] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.

[0024] like Figures 1 to 5 As shown, a fracture-resistant, high-temperature-resistant copper braided wire includes an inner core main wire group 1 and a secondary braided wire group 2. The secondary braided wire group 2 covers the inner core main wire group 1. The inner core main wire group 1 includes a main core 11 and a covering layer 12. The main core 11 is composed of copper wire 111 and steel wire 112. The diameter of the steel wire 112 is smaller than the diameter of the copper wire 111. Six steel wires 112 are arranged and are evenly twisted around the outer circumference of the copper wire 111, which improves the resistance of the main core to high temperature and fracture resistance. The core 11 has good bending and tensile strength. When the core 11 is subjected to tensile and bending forces, the steel wire 112 can protect the copper wire 111, prevent the copper wire 111 from being stretched and deformed too much, and ensure that the copper wire 111 will not break when it is bent. The covering layer 12 is set on the outside of the core 11, which firmly binds the six steel wires 112 to the outer circumference of the copper wire 111, preventing the steel wires 112 from moving and causing uneven distribution of materials inside the core 11, which would affect the overall performance of the core 11.

[0025] like Figure 4 As shown, a first adhesive layer 113 is provided on the outer circumferential surface of the copper wire 111. The first adhesive layer 113 is a polytetrafluoroethylene adhesive layer. A second adhesive layer 114 is provided on the outer side of the first adhesive layer 113. The second adhesive layer 114 is a polytetrafluoroethylene layer. A third adhesive layer 115 is provided on the outer side of the second adhesive layer 114. The third adhesive layer 115 is a corrosion-resistant rubber layer. This composite structure greatly improves the high temperature resistance of the copper wire 111.

[0026] like Figure 5As shown, the secondary wire braiding group 2 includes multiple secondary wires 21. The surface of the secondary wires 21 is cleaned with a cleaning agent composed of inorganic and organic acids to remove impurities and form a uniform, dense, and difficult-to-remove protective film on the surface of the secondary wires 21, improving the oxidation resistance and high temperature resistance of the secondary wires 21 and extending their service life. The multiple secondary wires 21 are cross-braided in a cross-braiding manner with a cross angle of 60°. The twisted structure formed by the cross-braiding improves the bending toughness of the secondary wire braiding group 2, thereby improving the tensile and bending performance of the copper braided wire. This effectively prevents the copper braided wire from undergoing large deformation and breakage under tension and bending forces. The service life of the copper braided wire is extended through the combined action of the steel wire 112 and the secondary wire braiding group 2.

[0027] The specific implementation method involves uniformly winding and twisting six steel wires 112 around the outer circumference of the copper wire 111, which improves the bending and tensile strength of the main core 11. When the main core 11 is subjected to tensile and bending forces, the steel wires 112 can protect the copper wire 111, preventing excessive tensile deformation and ensuring that the copper wire 111 will not break when bent. A polytetrafluoroethylene (PTFE) layer, a polytetrafluoroethylene (PTFE) layer, and a corrosion-resistant rubber layer are sequentially arranged on the outer circumference of the copper wire 111. This composite structure greatly improves the high-temperature resistance of the copper wire 111. The use of inorganic acid and... The organic acid compound cleaning agent cleans the surface of the sub-wire 21, removes impurities from the surface of the sub-wire 21, and forms a uniform, dense, and difficult-to-remove protective film on the surface of the sub-wire 21, improving the oxidation resistance and high temperature resistance of the sub-wire 21 and extending its service life. The cross-braiding method is used to cross-braid the sub-wire 21 to form a stranded structure, which improves the bending toughness of the sub-wire braid group 2, thereby improving the tensile and bending resistance of the copper braided wire. This effectively prevents the copper braided wire from undergoing large deformation and breakage under tension and bending force, and greatly extends the service life of the copper braided wire.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
