Description

Insulation dielectric structure and high-speed cable Technical Field

[0001] The present application relates to the field of signal transmission, and in particular to insulating dielectric structures and high-speed cables. Background Art

[0002] High-speed cables generally use differential line pairs for signal transmission. Their structure consists of two wires covered with an insulating medium. The insulating medium can be one layer or two or more layers.

[0003] As shown in Figure 1 , a high-speed cable 900 includes a pair of conductors 100 as a differential pair. Each conductor 100 is coated with an insulating medium 300. Two ground wires 200 are symmetrically arranged outside the differential pair. A shielding layer 400 covers the conductors 100, the insulating medium 300, and the ground wires 200. A jacket 500 covers the shielding layer 400, that is, the shielding layer 400 is covered with the jacket 500. Within the shielding layer 400, a gap 600 is defined between the two insulating mediums 300, and a gap 600 is defined between the insulating medium 300 and the ground wires 200. This type of high-speed cable 900 comprises a layer of insulating medium. It should be understood that the structure of the high-speed cable 900 shown in Figure 1 represents a cross-sectional view of the cable 900 along its extension direction, and the same applies hereinafter, so further description will not be given.

[0004] Another high-speed cable 900 is shown in FIG2 . Unlike the high-speed cable 900 shown in FIG1 , the shielding layer 400 covers the conductor 100 and the insulating medium 300 but does not cover the ground wire 200 . Furthermore, the insulating medium 300 is integrally formed, and the entire shielding layer 400, except for the conductor 100, is filled with the insulating medium 300 . There is no gap 600 within the shielding layer 400 . However, there is a gap 600 outside the shielding layer 400 between the shielding layer 400 and the ground wire 200 . This type of high-speed cable 900 also has only one layer of insulating medium.

[0005] Another high-speed cable 900 is shown in Figure 3. Unlike the high-speed cable 900 shown in Figure 2, the insulating medium 300 comprises two layers. Each conductor 100 is covered with a first insulating medium 310, and both first insulating media 310 are entirely covered with a second insulating medium 320. A shielding layer 400 is wrapped around the second insulating medium 320. The entire interior of the shielding layer 400, except for the conductors 100, is filled with the first and second insulating media 310, 320. This type of high-speed cable 900 has two layers of insulating medium. The same applies to high-speed cables 900 with multiple layers of insulating medium.

[0006] When air exists within the shielding layer 400 of the high-speed cable 900, as shown in Figure 1, gaps 600 within the shielding layer 400 minimize signal attenuation, as air is the optimal transmission medium. However, the cable structure shown in Figure 1 exhibits poor stability, and transmission performance can easily vary when the cable is bent or twisted. When the shielding layer 400 of the high-speed cable 900 is completely filled with the insulating medium 300, as shown in Figures 2 and 3, the cable 900 achieves optimal structural stability, but exhibits significant signal attenuation.

[0007] Therefore, how to balance the structural stability of high-speed cables and the signal transmission attenuation problem is a technical problem that needs to be solved urgently. Utility Model Content

[0060] The present application discloses an insulating dielectric structure and a high-speed cable, which include some or all of the technical features of the following embodiments; that is, the insulating dielectric structure and the high-speed cable include some or all of the following structures. In one embodiment of the present application, an insulating dielectric structure includes an insulating dielectric body and pores, wherein the pores are provided in the insulating dielectric body; wherein the pores include: a pair of first pores provided in the insulating dielectric body and axially symmetrically arranged, wherein the pair of first pores is used to pass a pair of conductors as a differential pair; and a pair of second pores, at least three in number, provided in the insulating dielectric body; and each of the second pores is axially symmetrically arranged relative to the symmetry axis of the pair of first pores. The above-mentioned insulating dielectric structure is applied to a high-speed cable. By preparing the insulating dielectric into a structure having pores, and these pores are axially symmetrically arranged relative to the symmetry axis, the insulating dielectric structure is used to ensure the effectiveness of the signal transmission of the high-speed cable. On the one hand, it is beneficial to ensure the structural stability of the high-speed cable and avoid the problem of performance variation of the high-speed cable when bending and torsion. On the other hand, it is beneficial to reduce signal transmission loss and thus reduce the degree of transmission attenuation.

[0061] The insulating dielectric structure and the high-speed cable are described in detail below with reference to FIG. 4 to FIG. 19 .

[0062] In order to solve the problem of how to balance the structural stability of the high-speed cable 900 with the signal transmission attenuation, in one embodiment, an insulating dielectric structure 700 is shown in FIG4 , which can be used in high-speed cables. Specifically, a high-speed cable 900 using the insulating dielectric structure 700 shown in FIG4 is shown in FIG5 . This application proposes a high-speed cable 900 that uses a lotus-core-like structure as the insulating dielectric structure 700. The important difference from conventional technology is that the insulating dielectric structure 700 is a porous structure that can be used in high-speed cables 900. That is, the insulating dielectric is made into a lotus-core structure with several circular or other shaped holes inside. This allows the internal structure to contain a large amount of air while ensuring sufficient mechanical strength as a whole, so that the performance of the wire does not vary when it is bent or twisted, thereby effectively solving the above-mentioned problem.

[0063] In conjunction with Figures 4 and 5 , in this embodiment, the high-speed cable 900 includes a conductor 100, a ground wire 200, a shielding layer 400, a jacket 500, and the insulating dielectric structure 700. A pair of conductors 100 are disposed in a pair of first apertures 301 of the insulating dielectric structure 700, one-to-one. The shielding layer 400 covers the insulating dielectric structure 700, and the jacket 500 covers the shielding layer 400 and the ground wire 200. The shielding layer 400 includes, but is not limited to, a metal shielding layer; the jacket 500 may also be referred to as a jacket layer. A gap 600 may be provided between the shielding layer 400 and the insulating dielectric structure 700; alternatively, as shown in Figure 5 , the shielding layer 400 may tightly cover the insulating dielectric structure 700, i.e., no gap 600 exists between the shielding layer 400 and the insulating dielectric structure 700. The high-speed cable 900 adopts the insulating medium structure 700, and is also prepared by preparing the insulating medium into a structure with pores, and these pores are arranged axially symmetrically with respect to the symmetry axis 800. Therefore, under the premise of ensuring the effectiveness of signal transmission of the high-speed cable 900, on the one hand, it is beneficial to ensure the structural stability of the high-speed cable 900 and avoid the problem of performance variation of the high-speed cable 900 when bending and torsion. On the other hand, it is beneficial to reduce signal transmission loss and thus reduce the degree of transmission attenuation.

[0064] In the high-speed cable 900, there are two conductors 100, also known as two strands. Each conductor 100 is a single or multiple strands of metal wire. The metal wire can be any of silver-plated copper, tin-plated copper, bare copper, silver-plated copper-clad steel, and silver-plated copper-clad aluminum. The cross-sectional shape of the metal wire can be circular, oval, flat, or any other shape. It is understood that for a differential pair, along the extension direction of the high-speed cable 900, a pair of the conductors 100 are symmetrically arranged. Figure 5 shows a cross-section along the extension direction of the high-speed cable 900. In this cross-section, the pair of conductors 100 have an axis of symmetry 800, which can also be understood as a pair of the first apertures 301 having the axis of symmetry 800. The same applies to the remaining embodiments. The high-speed cable 900 includes the insulating dielectric structure 700 described in any embodiment herein, which will not be described in detail below.

[0065] In conjunction with Figures 4 and 5, in one embodiment, the insulating dielectric structure 700 includes an insulating dielectric body 305 and pores, wherein the pores are provided in the insulating dielectric body 305; the insulating dielectric body 305 is coated on the outside of the conductor 100, and the material of the insulating dielectric body 305 is any one of polyethylene, polypropylene, polytetrafluoroethylene, polytetrafluoroethylene insulating dielectric body 305, polyvinylidene fluoride, or other fluoroplastics. The insulating dielectric body 305 is a single layer of insulating dielectric, and may also include two or more layers of different insulating dielectrics. The insulating dielectric body 305 has a plurality of hollow holes inside as the pores, and the shape of the hollow holes can be circular, square, or other shapes, and are generally distributed in a lotus-core shape on the cross-section of the insulating dielectric body 305, and the lotus-core holes are symmetrical on the left and right. This structural design makes the insulating dielectric structure 700 into a lotus-core structure, so that the entire high-speed cable 900 can improve the anti-attenuation performance while ensuring sufficient mechanical strength and anti-bending and torsion performance.

[0066] In each embodiment, the pores include a first pore 301 and a second pore 302. The shapes and sizes of the first pore 301 and the second pore 302 can be identical or different. In this embodiment, the insulating dielectric body 305 is arranged axially symmetrically with respect to the axis of symmetry 800. For example, as shown in Figures 4 and 5, the first pore 301 and the second pore 302 have the same shape, and the area of ​​the first pore 301 is larger than that of the second pore 302. It will be understood that the shapes and areas described in each embodiment are based on a cross-section along the extension direction of the high-speed cable 900. The same applies to the remaining embodiments and will not be further described.

[0067] To facilitate differential signal transmission, in each embodiment, the first apertures 301 are provided in a pair within the insulating dielectric body 305 and are arranged axially symmetrically. The pair of first apertures 301 is used to pass through a pair of conductors 100 as a differential pair. As previously described, the axis of symmetry 800 of the pair of first apertures 301 is the axis of symmetry 800 of the pair of conductors 100. It should be noted that the above description is based on the structure of the insulating dielectric structure 700. In actual production processes, the first apertures 301 may be structures formed due to the production process. For example, the insulating dielectric body 305 is filled outside the conductor 100, covered outside the conductor 100, or wound around the conductor 100, so that the conductor 100 is covered by the insulating dielectric body 305, thereby forming a space filled by the conductor 100 within the insulating dielectric body 305, with this space serving as the first aperture 301. Exemplarily, a tube body, such as a hollow tube, is first preset at the second pore 302 , and after the insulating medium body 305 is formed, the tube body is extruded or drawn out to form the second pore 302 .

[0068] To ensure that air is contained within the insulating dielectric structure 700, in each embodiment, at least three second pores 302 are provided within the insulating dielectric body 305. Furthermore, each second pore 302 is arranged symmetrically with respect to the axis of symmetry 800 of the pair of first pores 301. This structural design ensures that air is contained within the insulating dielectric structure 700, which helps reduce signal transmission loss and thus transmission attenuation.

[0069] In each embodiment, along the cross-section of the high-speed cable 900 extending in the direction of extension, the shape and size of the first aperture 301 are determined by the conductor 100, and the second aperture 302 is at least partially circular, at least partially elliptical, or at least partially regular polygonal, or all of them. That is, along the extending direction of the insulating dielectric body 305, the cross-section of the second aperture 302 is partially or fully circular, partially or fully elliptical, or partially or fully regular polygonal; that is, the cross-section of the second aperture 302 can be a combination of partially circular, partially elliptical, and / or partially regular polygonal. This structural design is also intended to ensure that the interior of the insulating dielectric structure 700 contains air, thereby reducing signal transmission loss and thus lowering transmission attenuation.

[0070] To facilitate differential signal transmission, in one embodiment, each second pore 302 is evenly divided into two groups, with each group of second pores 302 having a center of symmetry around the center of one of the first pores 301 and being centrally symmetrically distributed. That is, for embodiments in which the second pores 302 are not disposed along the axis of symmetry 800, the number of second pores 302 is an even number, so that each second pore 302 is disposed in axisymmetric fashion relative to the axis of symmetry 800. In the embodiments shown in Figures 4 and 5, there are 12 second pores 302, which are divided into two groups that are axisymmetric relative to the axis of symmetry 800. Each group of six second pores 302 has a center of symmetry around the center of one of the first pores 301 and is centrally symmetrically distributed. It will be understood that the specific number of second pores 302 in the above embodiments is merely an example and does not constitute an additional limitation to the present application, and will not be elaborated on below.

[0071] To facilitate differential signal transmission, in one embodiment, the second apertures 302 are evenly divided into three groups. Two of the groups of second apertures 302 are symmetrically distributed about the center of one of the first apertures 301. Another group of second apertures 302 is axisymmetrically arranged with respect to the axis of symmetry 800, that is, evenly distributed on the axis of symmetry 800. In one embodiment, as shown in Figures 6 and 7, the number of second apertures 302 is 16, divided into three groups that are axisymmetric with respect to the axis of symmetry 800. In two groups, each group of six second apertures 302 is symmetrically distributed about the center of one of the first apertures 301. Another group of four second apertures 302 is axisymmetrically arranged with respect to the axis of symmetry 800.

[0072] In order to further cooperate with the realization of differential signal transmission, in one embodiment, as shown in Figures 6 and 7, relative to the symmetry axis 800, the second pore 302 located on the symmetry axis 800 itself is axially symmetrically arranged relative to the symmetry axis 800, and the second pores 302 located on both sides of the symmetry axis 800 are axially symmetrically arranged; that is, the second pore 302 can also be set on the symmetry axis 800. In this case, the second pore 302 itself is an axially symmetrical shape, and the second pore 302 itself is axially symmetrically arranged relative to the symmetry axis 800.

[0073] To further increase the air capacity within the internal structure of the insulating dielectric structure 700, in one embodiment, the insulating dielectric body 305 is further provided with third pores 303. The passage area of ​​the third pores 303 is different from the passage area of ​​the second pores 302, and each third pore 303 is arranged axially symmetrically with respect to the symmetry axis 800. In one embodiment, the insulating dielectric structure 700 is shown in FIG8 , and the high-speed cable 900 using the insulating dielectric structure 700 shown in FIG8 is shown in FIG9 . Unlike the embodiments shown in FIG6 and FIG7 , the insulating dielectric body 305 is further provided with 13 third pores 303. The 13 third pores 303 are divided into three groups. In two groups, each group has five third pores 303 arranged axially symmetrically with respect to the symmetry axis 800. Another group has three third pores 303 evenly distributed on the symmetry axis 800, and the third pores 303 themselves are arranged axially symmetrically with respect to the symmetry axis 800. Such a structural design further ensures that the internal structure of the insulating medium structure 700 contains a large amount of air, which is beneficial to reducing signal transmission loss and thus reducing the degree of transmission attenuation. It is also beneficial to ensure the structural stability of the high-speed cable and avoid the problem of performance variation of the high-speed cable when it is bent and twisted.

[0074] In the embodiments shown in Figures 4 to 9, the insulating dielectric structure 700 has only one layer of insulating dielectric. In one embodiment, the insulating dielectric structure 700 is shown in Figure 10, and the high-speed cable 900 using the insulating dielectric structure 700 shown in Figure 10 is shown in Figure 11. The insulating dielectric body 305 includes a first insulating dielectric 310 and a second insulating dielectric 320, which can also be understood as the insulating dielectric body 305 being divided into the first insulating dielectric 310 and the second insulating dielectric 320. Each of the first pores 301 is covered with the first insulating dielectric 310, and the entire exterior of the two first insulating media 310 is covered with the second insulating dielectric 320. The first insulating dielectric 310 is provided with the second pore 302. The materials of the first insulating medium 310 and the second insulating medium 320 can be the same or different. In embodiments where the first insulating medium 310 and the second insulating medium 320 are made of the same material, they can be sequentially implemented using a predetermined process. The specific implementation methods of the first insulating medium 310, the second insulating medium 320, and the third insulating medium 330 (described below) are conventional and are not limited to these by comparison with the various embodiments of this application. This structural design also allows the internal structure of the insulating medium structure 700 to contain a large amount of air.

[0075] In the embodiments shown in Figures 10 and 11 , the second pores 302 are only provided in the first insulating medium 310. In other embodiments, as shown in Figures 12 and 13 , the second insulating medium 320 also has the second pores 302. In this embodiment, the second pores 302 in the second insulating medium 320 are evenly distributed along the axis of symmetry 800, and the second pores 302 in the second insulating medium 320 are themselves arranged axially symmetrically with respect to the axis of symmetry 800. This structural design helps to increase the air content within the insulating medium structure 700.

[0076] In one embodiment, the insulating dielectric structure 700 is shown in FIG14 , and the high-speed cable 900 using the insulating dielectric structure 700 shown in FIG14 is shown in FIG15 . The first insulating dielectric 310 is further provided with third pores 303. The passage area of ​​the third pores 303 is different from the passage area of ​​the second pores 302, and the third pores 303 are arranged axially symmetrically with respect to the symmetry axis 800. This structural design further increases the air content within the insulating dielectric structure 700, helps reduce signal transmission loss and thus transmission attenuation, ensures the effectiveness of high-speed cable signal transmission, and can also help increase the signal transmission distance of the high-speed cable.

[0077] In one embodiment, the insulating dielectric body 305 is further provided with fourth pores 304. The passage area of ​​the fourth pores 304 is different from the passage area of ​​the second pores 302 and the third pores 303. Furthermore, the fourth pores 304 are arranged symmetrically with respect to the axis of symmetry 800. This structural design, while ensuring the structural stability of the high-speed cable, can form more and denser air channels, allowing the internal structure of the insulating dielectric structure 700 to contain a large amount of air, which helps reduce signal transmission loss and thus transmission attenuation.

[0078] In one embodiment, the insulating dielectric structure 700 is shown in FIG16 , and the high-speed cable 900 using the insulating dielectric structure 700 shown in FIG16 is shown in FIG17 . Unlike the embodiments shown in FIG14 and FIG15 , the second insulating dielectric 320 is provided with fourth pores 304. The passage area of ​​the fourth pores 304 is different from the passage area of ​​the second pores 302, and the fourth pores 304 are arranged axially symmetrically with respect to the symmetry axis 800. That is, in this embodiment, the first insulating dielectric 310 is provided with second pores 302 and third pores 303, and the second insulating dielectric 320 is provided with fourth pores 304. This structural design ensures that the insulating dielectric structure 700 maintains sufficient structural strength, ensuring transmission performance during bending and torsion. Furthermore, it can fully utilize the air in the pores as a transmission medium to reduce signal transmission loss and thus lower signal transmission attenuation, making it particularly suitable for long-distance transmission.

[0079] To enhance the structural strength of the insulating medium structure 700 at the pores, in one embodiment, as shown in Figures 18 and 19 , the insulating medium body 305 includes a second insulating medium 320 and a third insulating medium 330. The third insulating medium 330 is provided with the second pores 302, i.e., the second pores 302 are located within the third insulating medium 330, i.e., the third insulating medium 330 covers the second pores 302. The remaining embodiments are similar and will not be described in detail. Furthermore, the second insulating medium 320 is entirely covered by the third insulating medium 330 and the two first pores 301. Furthermore, in one embodiment, the material of the second insulating medium 320 is different from that of the third insulating medium 330. In this embodiment, the insulating medium body 305 further includes a first insulating medium 310. Each of the first apertures 301 is covered with the first insulating medium 310. Furthermore, the first insulating medium 310 is entirely covered by the third insulating medium 330 and the two first apertures 301. Alternatively, the third insulating medium 330 and the first insulating medium 310 are separated by the second insulating medium 320. This structural design improves the structural strength of the second apertures 302 to a certain extent, further preventing performance variations of the high-speed cable 900 during bending and torsion, thereby ensuring the effectiveness of signal transmission in the high-speed cable 900 and further increasing the effective transmission distance of the high-speed cable 900.

[0080] Furthermore, in one embodiment, for an embodiment having a third aperture 303 and / or a fourth aperture 304, the third aperture 303 and / or the fourth aperture 304 are also located in the third insulating medium 330. This structural design improves the structural strength of the third aperture 303 and / or the fourth aperture 304 to a certain extent, thereby reducing signal transmission loss and thus transmission attenuation. It also helps prevent performance variations of the high-speed cable 900 during bending and torsion, thereby ensuring the effectiveness of signal transmission of the high-speed cable 900 and further increasing the effective transmission distance of the high-speed cable 900.

[0081] It should be noted that other embodiments of the present application also include practicable insulating dielectric structures and high-speed cables formed by combining the technical features of the above embodiments. In each embodiment, the insulating dielectric structure is applied to the high-speed cable; in each embodiment, the high-speed cable can also be referred to as a differential cable or a differential transmission cable.

[0082] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of patent protection for the present application shall be determined by the appended claims.
