[0032] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0033] In the description of the embodiments of this application, words such as "for example" or "for instance" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "for example" or "for instance" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "for example" or "for instance" is intended to present the relevant concepts in a concrete manner.

[0034] In the description of the embodiments of the present application, the term "multiple" means two or more. For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized.

[0035] The present application is further described in detail below with reference to the accompanying drawings.

[0036] See also Figure 1 In an embodiment of the present application, a high-temperature resistant drag chain line is disclosed, comprising: a first core layer 10, a first insulating layer 30, a first temperature-resistant layer 40, and a second insulating layer 50 wrapped in sequence.

[0037] The first core layer 10 is made of nickel alloy wire to form the core of the drag chain cable, which can make the core have good conductivity, high temperature resistance, and bending resistance. The first insulation layer 30 is wrapped around the outside of the first core layer 10 to provide electrical insulation protection. The first heat-resistant layer 40 is wrapped around the outside of the first insulation layer 30 away from the first core layer 10 to enhance the overall heat resistance of the drag chain cable. The second insulation layer 50 is further wrapped around the outside of the first heat-resistant layer 40 away from the first insulation layer 30, forming a multi-layer protection structure to ensure the stability and safety of the drag chain cable in high-temperature environments, thereby ensuring stable current transmission.

[0038] Furthermore, the drag chain line also includes a second core layer 20 , which is made of copper-nickel wire, tightly surrounding the periphery of the first core layer 10 , and located between the first core layer 10 and the first insulating layer 30 .

[0039] The addition of copper-nickel wire not only enhances electrical conductivity but also further improves the drag chain's high-temperature resistance. Furthermore, by tightly surrounding the first core layer 10 with the copper-nickel wire second core layer 20, the structural stability between the core layers is enhanced while also improving overall electrical and thermal conductivity. Furthermore, this tightly surrounding design allows for more effective heat dissipation, thereby improving the drag chain's operational stability and durability in high-temperature environments.

[0040] Specifically, in this embodiment, the first insulating layer 30 is made of Teflon material as an insulating layer of the drag chain cable, seamlessly and evenly wrapped around the outside of the first core layer 10 to provide excellent insulation protection.

[0041] Among them, this seamless and uniform wrapping method can ensure the integrity and consistency of the insulation layer, prevent electrical failures caused by uneven insulation layer or gaps, and thus improve the safety and reliability of the drag chain line.

[0042] In another embodiment, the first insulating layer 30 may also be made of other high-temperature resistant insulating materials besides Teflon, such as polyimide or polyetheretherketone. These materials also have good high-temperature resistance and electrical insulation properties and can be used as substitutes for Teflon to adapt to different application environments and cost requirements.

[0043] The first temperature-resistant layer 40 uses mica tape as the temperature-resistant layer of the drag chain line, and is tightly covered on the first insulating layer 30 by winding, so as to improve the high-temperature resistance of the drag chain line.

[0044] The mica tape can be wound using cross-winding at different angles or multiple layers of overlapping winding to enhance its coverage and high-temperature resistance on the drag chain. Different winding methods can be adjusted based on actual process requirements and high-temperature resistance requirements.

[0045] The second insulating layer 50 is made of glass fiber as another insulating layer of the drag chain line, and is also the outer skin of the drag chain line. It is evenly and tightly wrapped around the outside of the first temperature-resistant layer 40, which can further enhance electrical insulation and structural stability.

[0046] The second insulating layer 50 of fiberglass is evenly and tightly wrapped around the mica tape. This tight and uniform wrapping ensures that the second insulating layer 50 protects the internal structure while also helping to improve the overall structural stability and high-temperature resistance.

[0047] In another embodiment, the second insulating layer 50 may be made of other high-temperature resistant insulating materials, such as ceramic fiber or quartz fiber, in addition to glass fiber. These materials have high-temperature stability and excellent electrical insulation properties, which can effectively improve the safety and durability of the drag chain cable in high-temperature environments.

[0048] In summary, the embodiment of the present application discloses a high-temperature resistant drag chain cable. By using a high-temperature resistant and bend-resistant nickel alloy wire as the first core layer 10, the stable transmission of current can be ensured. The second core layer 20 composed of copper-nickel wire is tightly surrounded by the periphery of the first core layer 10, which can enhance the structural stability between the core layers and help improve the overall electrical and thermal conductivity. The first insulating layer 30 made of Teflon material provides electrical insulation protection and can withstand the test of high-temperature environments. The use of mica tape as the first heat-resistant layer 40 can enhance the overall high-temperature resistance. The second insulating layer 50 made of glass fiber can further enhance the electrical insulation and structural stability. In this way, the multi-layer structural design makes the drag chain cable not only have high-temperature resistance and bend-resistant properties in high-temperature environments, but also ensure the stable transmission of current.

[0049] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
