Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of wires and cables, and in particular to a Teflon wire. Background Technology
[0002] With the widespread use of electronic devices, the requirements for the durability and impermeability of wires are becoming increasingly stringent. Teflon wires, commonly known as fluoroplastic wires or high-temperature wires, are wires whose insulation layer is made of fluoroplastics. They possess special high-temperature resistance properties and are therefore widely used in electronic devices.
[0003] Existing Teflon wires generally consist of a conductor and an insulation layer made of Teflon material, a metal sheath layer surrounding the conductor, and a filler layer.
[0004] However, existing Teflon wires are easily damaged in environments with impregnation varnish or other chemicals, leading to a decrease in conductivity. Utility Model Content
[0005] The purpose of this invention is to provide a Teflon wire that solves the technical problem that Teflon wires are easily damaged in environments with impregnation varnish or other chemicals, leading to a decrease in conductivity.
[0006] In the first aspect, the present invention provides a Teflon wire, comprising a core assembly, a first potting layer, a shielding layer, a second potting layer, and an outer sheath;
[0007] The core assembly is disposed on the first potting layer, the shielding layer is sleeved on the outer surface of the first potting layer, the outer sheath is sleeved on the outside of the shielding layer, and the second potting layer is potted between the outer sheath and the shielding layer;
[0008] The outer sheath is made of Teflon material.
[0009] Furthermore, both the first potting layer and the second potting layer are made of potting silicone.
[0010] Furthermore, multiple cables are twisted together to form the core assembly.
[0011] Furthermore, the cable includes a conductor and an insulating layer sleeved on the conductor, the insulating layer being made of Teflon material.
[0012] Furthermore, the shielding layer is made of tin-plated copper wire braid, and the braiding density of the shielding layer is greater than or equal to 30%.
[0013] Compared with the prior art, the present invention provides a Teflon wire, including a core assembly, a first potting layer, a shielding layer, a second potting layer, and an outer sheath. The core assembly is disposed on the first potting layer, the shielding layer is sleeved on the outer surface of the first potting layer, the outer sheath is sleeved on the outside of the shielding layer, and the second potting layer is filled between the outer sheath and the shielding layer. The outer sheath is made of Teflon material. By potting two layers of silicone on the inner and outer sides of the shielding layer at one time, the gaps of the core assembly are filled, effectively preventing external impregnation paint or other chemicals from penetrating into the core assembly. At the same time, the gaps of the shielding layer are filled, so that the shielding layer is completely sealed by the potting silicone, effectively preventing external impregnation paint or other chemicals from penetrating into the interior of the shielding layer. This solves the technical problem in the prior art that Teflon wires are easily damaged in the environment of impregnation paint or other chemicals, resulting in a decrease in conductivity. This makes the Teflon wire waterproof, moisture-proof, insulating, and corrosion-resistant. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the 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.
[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0021] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
[0023] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0025] like Figure 1 As shown, this utility model embodiment provides a Teflon wire, including a core assembly, a first potting layer, a shielding layer, a second potting layer, and an outer sheath; the core assembly is disposed on the first potting layer, the shielding layer is sleeved on the outer surface of the first potting layer, the outer sheath is sleeved on the outside of the shielding layer, and the second potting layer is potted between the outer sheath and the shielding layer; the outer sheath is made of Teflon material.
[0026] Specifically, the Teflon wire provided by this utility model fills the gaps in the core assembly by potting two layers of silicone on both the inner and outer sides of the shielding layer at once. This effectively prevents external impregnation paint or other chemicals from penetrating into the core assembly. At the same time, it fills the gaps in the shielding layer, making the shielding layer completely sealed by the potting silicone. This effectively prevents external impregnation paint or other chemicals from penetrating into the interior of the shielding layer. This solves the technical problem in the prior art that Teflon wires are easily damaged in the environment of impregnation paint or other chemicals, resulting in a decrease in conductivity. This makes the Teflon wire waterproof, moisture-proof, insulating, and corrosion-resistant.
[0027] Specifically, the core assembly is made of multiple stranded cables; in this embodiment, it is made of three stranded cables arranged in a triangular pattern. A cylindrical shielding layer is fitted over the outside of the core assembly, and a first potting layer is applied between the core assembly and the shielding layer. The outer sheath is made of Teflon material with a thickness of 0.13 mm, which provides good resistance to most chemicals (including strong acids, strong alkalis, and organic solvents) and maintains performance in harsh environments. A second potting layer is applied between the shielding layer and the outer sheath, filling the gaps in the shielding layer.
[0028] Furthermore, the cable includes a conductor and an insulation layer sleeved on the conductor, the insulation layer being made of Teflon material.
[0029] Specifically, in this embodiment, the conductor is made of silver-plated copper wire stranded together, which has good electrical conductivity. The insulation layer is made of Teflon, which has good resistance to most chemicals (including strong acids, strong alkalis and organic solvents) and can maintain its performance in harsh environments.
[0030] Preferably, both the first potting layer and the second potting layer are made of potting silicone.
[0031] Specifically, the first potting layer uses potting silicone, which fills the gaps in the insulation layer after cabling, completely sealing the insulation layer and effectively preventing external impregnating varnish or other chemicals from penetrating into it. The second potting layer uses potting silicone, which fills the gaps in the shielding layer, completely sealing it and effectively preventing external impregnating varnish or other chemicals from penetrating into it. The potting silicone provides waterproofing, moisture resistance, dustproofing, insulation, thermal conductivity, sealing, corrosion resistance, temperature resistance, and shock absorption.
[0032] Furthermore, the shielding layer is made of tin-plated copper wire braid, and the braiding density of the shielding layer is greater than or equal to 30%.
[0033] Specifically, the shielding is made of tin-plated copper wire braid with a braiding density of 85%, which provides good anti-shielding performance.
[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
