Description

Technical Field

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

[0002] The wire and cable industry is an important supporting industry for economic construction, widely used in various sectors of the national economy. UTP (Unshielded Twisted Pair) cable generally refers to unshielded twisted pair data cable. It features a small outer diameter and lightweight design, making it suitable for installation in the confined spaces within robot arms, and is therefore commonly used for cabling inside the hands and feet of robots.

[0003] Existing UTP cables typically have an insulation layer covering the conductor, and the conductor and insulation layer form the cable's insulated wires; two insulated wires are twisted together to form an insulated pair, which in turn form the core, and a protective layer is placed on the outside to protect it.

[0004] However, once the operating temperature of existing UTP cables exceeds 100 degrees Celsius, the insulation layer will age rapidly and will not be able to meet the needs of the robotic arm's extensive bending and friction. Furthermore, the signal transmission performance will be significantly reduced as the insulation is damaged, making it difficult to meet the high-speed transmission requirements, and the core chip's function cannot be effectively transmitted to the damaged area. Utility Model Content

[0005] The purpose of this invention is to provide a high-temperature and wear-resistant UTP cable to solve the technical problem that existing UTP cables are difficult to adapt to high-temperature and high-friction environments.

[0006] In the first aspect, the present invention provides a high-temperature and wear-resistant UTP cable, comprising a conductor core, a first insulation layer, a second insulation layer, and a wrapping layer;

[0007] The first insulating layer is sleeved on the conductor core, the second insulating layer is sleeved on the first insulating layer, the conductor core, the first insulating layer and the second insulating layer surround to form a conductor core cable, two conductor core cables are arranged parallel to each other along a direction perpendicular to their extension direction to form a conductor core group, and the wrapping layer is sleeved on the conductor core group.

[0008] Furthermore, the first insulating layer is made of expanded polytetrafluoroethylene tape wrapped around it.

[0009] Furthermore, the thickness of the first insulating layer is set to 0.035–0.051 mm.

[0010] Furthermore, the second insulating layer is made of polytetrafluoroethylene tape wrapped around it.

[0011] Furthermore, the thickness of the second insulating layer is set to 0.076–0.204 mm.

[0012] Furthermore, the wrapping layer is made of polytetrafluoroethylene raw material tape.

[0013] Furthermore, the wrapping coverage of the wrapping layer is set to 48% to 52%.

[0014] Compared with the prior art, the present invention provides a high-temperature and wear-resistant UTP cable, comprising a conductor core, a first insulation layer, a second insulation layer, and a wrapping layer; the first insulation layer is sleeved on the conductor core, the second insulation layer is sleeved on the first insulation layer, the conductor core, the first insulation layer, and the second insulation layer surround to form a conductor core cable, and the two conductor core cables are arranged parallel to each other along a direction perpendicular to their extension to form a conductor core group, and the wrapping layer is sleeved on the conductor core group; by sequentially setting the first insulation layer and the second insulation layer outside the conductor core, the high-temperature resistance of the cable is improved without excessively increasing the cable size, and the wear resistance of the cable is improved by the wrapping layer, thus solving the technical problem that UTP cables in the prior art are difficult to adapt to high-temperature and high-wear environments, and ensuring the stable transmission capability of the UTP cable in high-temperature environments.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

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.

[0021] 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.

[0022] 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.

[0025] 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.

[0026] like Figure 1As shown, this utility model embodiment provides a high-temperature and wear-resistant UTP cable, including a conductor core, a first insulation layer 200, a second insulation layer 300, and a wrapping layer 400; the first insulation layer 200 is sleeved on the conductor core, the second insulation layer 300 is sleeved on the first insulation layer 200, the conductor core, the first insulation layer 200, and the second insulation layer 300 surround to form a conductor core cable, the two conductor core cables are arranged parallel to each other along a direction perpendicular to their extension direction to form a conductor core group, and the wrapping layer 400 is sleeved on the conductor core group.

[0027] That is, the high-temperature and wear-resistant UTP cable provided by this utility model improves the high-temperature resistance of the cable without excessively increasing the cable size by sequentially setting a first insulation layer 200 and a second insulation layer 300 outside the core conductor. At the same time, the wear resistance of the cable is improved by the wrapping layer 400. This solves the technical problem that UTP cables in the prior art are difficult to adapt to high-temperature and high-wear environments, and ensures the stable transmission capability of UTP cables in high-temperature environments.

[0028] Specifically, the conductor core 100 is made of silver-plated copper wire stranded together. Silver has good temperature resistance, allowing it to be used in high-temperature environments, and it also has better conductivity and oxidation resistance. Furthermore, the silver-plated copper conductor has excellent mechanical properties and good corrosion resistance, allowing it to be used in acidic, alkaline, and high-temperature environments without easily corroding or oxidizing. The first insulation layer 200 can be wrapped around the outside of the conductor core 100, while the second insulation layer 300 can be wrapped or extruded around the outside of the first insulation layer 200. This forms a three-layer cable structure. Two cables are arranged side-by-side to form a core group, which is then wrapped by the wrapping layer 400 to ultimately form a complete high-temperature and abrasion-resistant UTP cable.

[0029] Furthermore, the first insulating layer 200 is made of expanded polytetrafluoroethylene tape wrapped around it.

[0030] Specifically, expanded polytetrafluoroethylene (ePTFE) tape is used for wrapping. ePTFE is a plastic material with high temperature resistance and good dielectric properties. Moreover, it exhibits excellent electrical insulation at high temperatures and frequencies, and has non-hygroscopic properties and excellent mechanical properties. Its long-term operating temperature can reach 250℃. It also has high electrical insulation performance, ablation resistance, thermal shock resistance, excellent dielectric properties, and good chemical stability.

[0031] Preferably, the thickness of the first insulating layer 200 is set to 0.035 to 0.051 mm.

[0032] Specifically, in this embodiment, the thickness of the first insulation layer 200 is set to 0.04 mm, which ensures that the first insulation layer 200 has good high temperature resistance while also ensuring that the overall size of the cable is not too thick.

[0033] Furthermore, the second insulating layer 300 is made of polytetrafluoroethylene tape wrapped around it.

[0034] Specifically, the second insulation layer 300 is made by wrapping and sintering polytetrafluoroethylene (PTFE) raw material tape. PTFE combines the excellent dielectric properties of expanded PTFE with a very smooth surface after sintering, exhibiting strong wear and bending resistance, and further improving the cable's high-temperature resistance.

[0035] Preferably, the thickness of the second insulating layer 300 is set to 0.076 to 0.204 mm.

[0036] Specifically, in this embodiment, the thickness of the second insulation layer 300 is set to 0.1 mm, which ensures that the second insulation layer 300 has good high temperature resistance while also ensuring that the overall size of the cable is not too thick.

[0037] Furthermore, the wrapping layer 400 is made of polytetrafluoroethylene raw material tape.

[0038] Specifically, the wrapping layer 400 is made of polytetrafluoroethylene (PTFE) raw material tape. After sintering, the PTFE raw material tape has excellent wear resistance, which can effectively protect the insulation structure from mechanical damage. By setting the wrapping layer 400, the mechanical strength and tensile strength of the cable are increased, ensuring the reliability of the wire and cable.

[0039] Furthermore, the wrapping coverage of the wrapping layer 400 is set to 48% to 52%.

[0040] Specifically, the wrapping coverage of the wrapping layer 400 is set to 50%.

[0041] This embodiment provides a high-temperature and wear-resistant UTP cable. The conductor core 100 is made of silver-plated copper material with excellent high-temperature resistance and conductivity, exhibiting good conductivity. The first insulation layer 200 and the second insulation layer 300 are made of PTFE tape and expanded PTFE tape, forming a composite insulation that provides excellent high-temperature resistance and wear resistance. The excellent dielectric properties allow high-speed signals to maintain superior stability, and the signal energy is not significantly lost due to the insulation material. Even without shielding, stable transmission can be maintained, maximizing signal integrity. The outermost layer is wrapped with PTFE raw material tape, effectively protecting the insulation structure from mechanical damage and increasing the mechanical strength of the cable. The high-temperature resistance of PTFE also improves the cable's temperature rating.

[0042] 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.
