Description

Technical Field

[0001] This utility model relates to the field of high-frequency wire technology, specifically a novel high-frequency wire structure. Background Technology

[0002] High-frequency cables are cables used to transmit high-frequency signals, characterized by low transmission loss and high electrical signal transmission capability. The frequency range of high-frequency cables is generally between 100MHz and 10GHz, and they are mainly used in antennas, radio frequency modules, and wireless communication.

[0003] Traditional high-frequency cables use ordinary stranded copper technology, which has the following problems:

[0004] (1) There are obvious gaps between the stranded conductors, which leads to enhanced capacitance effect and increased attenuation during signal transmission;

[0005] (2) If the stranding stress is not eliminated, it can easily lead to conductor deformation or breakage;

[0006] (3) Large deviation in insulation layer thickness affects impedance stability. Utility Model Content

[0007] The purpose of this invention is to provide a novel high-frequency wire structure to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a novel high-frequency wire structure, comprising a wire body, the wire body comprising a conductor and an insulating jacket, the conductor being formed by tightly pressing and hinged multiple outer conductive wires and one inner conductive wire, the conductor being covered by an insulating jacket.

[0009] The insulation jacket thickness uniformity deviation is ≤5%, the twisting pitch of the multi-strand outer conductive wire and the single inner conductive wire is 3.5-7.5mm, and the twisting direction is alternating between S and Z directions. The conductor's advantages include a certain degree of flexibility, the ability to withstand certain external forces and bending, and resistance to breakage. Furthermore, because the multi-strand outer conductive wire and the single inner conductive wire are twisted together, its conductivity is stronger, generally better than that of a single large-diameter copper wire. Compact hinge also improves transmission efficiency. By optimizing the conductor arrangement and twisting method, the conductor resistance can be reduced, lowering energy loss during signal transmission, thereby improving signal transmission efficiency and distance. Compact hinge, by tightly arranging and twisting the conductors, can effectively reduce interference during signal transmission. In signal transmission, especially in high-frequency signal transmission, the length and layout of the signal line have a significant impact on signal quality. Compact hinge, by reducing the distance between conductors, reduces the capacitance effect, thereby reducing crosstalk and radiation interference during signal transmission, improving signal transmission quality and stability. During stranding, the conductors are compressed by circular pressure rollers or circular compaction dies, reducing the gaps between the individual wires. The conductors remain circular, and the cross-sectional area remains unchanged, but the outer diameter is reduced. This allows for a reduction in the amount of insulation and sheathing materials used, as well as a smaller outer diameter of the finished cable. Compacted circular conductors are generally used in low-voltage, medium-voltage, and high-voltage power cables and overhead insulated cables.

[0010] Preferably, after the outer conductive wire and the inner conductive wire are tightly pressed and hinged, the shape becomes irregular, and the gap between the outer conductive wire and the inner conductive wire becomes smaller, with no gap or a gap ≤0.02mm between individual wires.

[0011] Preferably, the conductor has a circular cross-section and is formed by diamond eye mold compression molding, with the mold entrance angle α being 70°±20° and the compression zone angle γ being 16°±2°.

[0012] Preferably, the outer conductive wire and the inner conductive wire are made of copper, aluminum, or other materials with good conductivity.

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

[0014] First, by tightly pressing and hinged, multiple external conductive wires and one internal conductive wire are tightly combined, effectively eliminating the obvious gaps between single wires in traditional stranded conductors. This significantly reduces the capacitance effect during signal transmission, reduces signal attenuation, and improves signal transmission efficiency and stability.

[0015] Secondly, the tightly wound conductor structure gives the conductor a certain degree of flexibility, enabling it to withstand external forces and bending, and making it less prone to breakage, thus improving the durability and reliability of the wire. At the same time, this structure also optimizes the conductor arrangement and stranding method, further reducing conductor resistance and lowering energy loss during signal transmission.

[0016] Furthermore, the insulation jacket of this invention exhibits minimal thickness uniformity, ensuring impedance stability and further improving signal transmission quality. Moreover, the use of materials with excellent conductivity, such as copper or aluminum, for both the outer and inner conductive wires further enhances the wire's conductivity and reliability.

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figure 1-2 This utility model provides a novel high-frequency wire structure, including a wire body 1. The wire body 1 includes a conductor and an insulating jacket 4. The conductor is formed by tightly pressing and hinged multiple outer conductive wires 2 and one inner conductive wire 3. The conductor is covered with an insulating jacket 4.

[0022] Specifically, the insulation jacket 4 has a thickness uniformity deviation of ≤5%, and the twisting pitch of the multi-strand outer conductive wire 2 and the single inner conductive wire 3 is 3.5-7.5mm, with alternating S-direction or Z-direction twisting. The conductor's advantages include a certain degree of flexibility, the ability to withstand external force and bending, and resistance to breakage. Furthermore, because the multi-strand outer conductive wire 2 and the single inner conductive wire 3 are twisted together, their conductivity is stronger, generally better than that of a single large-diameter copper wire in terms of conductivity and reliability. Compact hinge also improves transmission efficiency. By optimizing the conductor arrangement and twisting method, the conductor resistance can be reduced, lowering energy loss during signal transmission and thus improving signal transmission efficiency and distance. Compact hinge, by tightly arranging and twisting the conductors, effectively reduces interference during signal transmission. In signal transmission, especially in high-frequency signal transmission, the length and layout of the signal line have a significant impact on signal quality. Compact hinge, by reducing the distance between conductors, reduces the capacitance effect, thereby reducing crosstalk and radiation interference during signal transmission and improving signal transmission quality and stability. During stranding, the conductors are compressed by circular pressure rollers or circular compaction dies, reducing the gaps between the individual wires. The conductors remain circular, and the cross-sectional area remains unchanged, but the outer diameter is reduced. This allows for a reduction in the amount of insulation and sheathing materials used, as well as a smaller outer diameter of the finished cable. Compacted circular conductors are generally used in low-voltage, medium-voltage, and high-voltage power cables and overhead insulated cables.

[0023] After the outer conductive wire 2 and the inner conductive wire 3 are tightly pressed and hinged, the shape becomes irregular, and the gap 5 between the outer conductive wire 2 and the inner conductive wire 3 becomes smaller, with no gap between the single wires or a gap 5 ≤ 0.02mm.

[0024] Specifically, the conductor is pressed tightly by a circular pressure roller or a circular pressing die to reduce the gap between the individual wires of the stranded conductor. The conductor remains circular, and the cross-sectional area of ​​the conductor remains unchanged, but the outer diameter of the conductor becomes smaller.

[0025] The conductor has a circular cross-section and is formed by diamond eye mold compression. The mold entrance angle α is 70°±20° and the compression zone angle γ is 16°±2°.

[0026] Specifically, this design ensures that the conductor achieves a uniform shape during compression, while guaranteeing the stability of its physical and electrical properties. Furthermore, this design helps improve the conductor's density, further reducing interference during signal transmission and enhancing signal transmission quality and stability.

[0027] The outer conductive wire 2 and the inner conductive wire 3 are made of copper, aluminum or other materials with good conductivity.

[0028] Working Principle: When a high-frequency signal passes through this new type of wire, the tightly twisted structure of the outer conductive wire 2 and the inner conductive wire 3 effectively reduces electromagnetic interference and signal loss during signal transmission. Due to the compaction process, the gaps 5 between individual wires are significantly reduced, even reaching a state of no gaps or gaps ≤ 0.02mm, which greatly improves the conductor's density and signal transmission efficiency. Simultaneously, the diamond-eye die compaction design ensures the uniformity of the conductor's shape, further stabilizing its physical and electrical properties, making signal transmission more stable and reliable. Furthermore, using materials with good conductivity, such as copper or aluminum, to make the outer conductive wire 2 and the inner conductive wire 3 further enhances the wire's conductivity and overall performance, meeting the high requirements of high-frequency signal transmission.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
