Technical Field
[0001] The utility model relates to an amplitude-stabilized and phase-stabilized coaxial cable. Background Art
[0002] In modern power and communication systems, cables, as key transmission media, need to have high-performance transmission characteristics and strong environmental adaptability. With the development of technology and the diversification of application scenarios, the performance requirements for cables are also increasing.
[0003] Cables are subjected to various mechanical stresses during installation and use, such as tension, bending, compression, etc. These stresses may cause internal delamination of the cable, damage the internal structure of the cable, and lead to performance degradation or failure. Utility Model Content
[0004] The main purpose of the utility model is to provide an amplitude-stabilized and phase-stabilized coaxial cable to solve the problems raised in the above background technology.
[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:
[0006] A stable amplitude and stable phase coaxial cable comprises an inner conductor, an insulator is arranged on the outer side of the inner conductor, the inner wall of the insulator is a circular structure, the outer wall of the insulator is a wavy structure, a shielding layer is arranged on the outer side of the insulator, the shielding layer is a wavy structure, and a protective skin is arranged on the outer side of the shielding layer.
[0007] Preferably, a foam body is provided between the shielding layer and the protective skin.
[0008] Preferably, the inner wall of the foam body is a wave-shaped structure, and the outer wall of the foam body is a circular structure.
[0009] Preferably, a skeleton is provided inside the foam body.
[0010] Preferably, the skeleton comprises a plurality of webs spaced apart from each other along the circumference of the foam body and an annular plate connecting the plurality of webs.
[0011] Preferably, the number of the webs is the same as the number of the wave valleys of the shielding layer, and the inner sides of the webs abut against the wave valleys of the shielding layer.
[0012] Preferably, a tensile layer is provided between the foam body and the protective skin.
[0013] Beneficial technical effects of the utility model:
[0014] 1. The insulator with a wavy outer wall and the wavy shielding layer provided by the utility model increase the contact area between the two, which is conducive to improving the adhesion between the layers, thereby reducing the risk of delamination, and also increases the area of the shielding layer itself, improving the shielding effectiveness against electromagnetic interference. In addition, when subjected to external mechanical forces, the wavy shape can better disperse stress at the edge and avoid stress concentration at a single point, which helps to maintain the integrity of the internal structure.
[0015] 2. The foam and skeleton provided by the utility model can provide additional protection. The foam has energy absorption and shock absorption functions, which effectively alleviates the impact of external impact on sensitive components inside the cable. The skeleton provides a solid support for the cable, enhances the overall compression, bending and torsion resistance of the cable, and enables it to withstand more mechanical pressure and external impact.

[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.
[0022] like Figure 1-Figure 4 As shown, the amplitude-stabilized and phase-stabilized coaxial cable provided in this embodiment includes an inner conductor 1, an insulator 2 is arranged on the outside of the inner conductor 1, the inner wall of the insulator 2 is a circular structure, the outer wall of the insulator 2 is a wavy structure, a shielding layer 3 is arranged on the outside of the insulator 2, the shielding layer 3 is a wavy structure, and a protective skin 4 is arranged on the outside of the shielding layer 3. The insulator 2 with a wavy outer wall and the wavy shielding layer 3 increase the contact area between the two, which is beneficial to improve the adhesion between the layers, thereby reducing the risk of delamination, and also increases the area of the shielding layer 3 itself, thereby improving the shielding effectiveness against electromagnetic interference.
[0023] In this embodiment, if Figure 1 As shown, a foam body 5 is arranged between the shielding layer 3 and the protective skin 4. The foam body 5 has energy absorption and shock absorption functions, which can effectively alleviate the impact of external impact on sensitive components inside the cable. It can also be used as a heat insulation material to help the cable maintain stable performance when the temperature changes.
[0024] In this embodiment, if Figure 1 As shown, the inner wall of the foam body 5 is a wavy structure, and the outer wall of the foam body 5 is a circular structure, which cooperates with the wavy shielding layer 3 to facilitate the adhesion between the layers and reduce the possibility of delamination.
[0025] In this embodiment, if Figure 1 As shown, a skeleton 6 is arranged inside the foam body 5. The skeleton 6 includes a plurality of webs 601 arranged at intervals along the circumference of the foam body 5 and an annular plate 602 connecting the plurality of webs 601, providing uniform supporting force along the circumference to maintain the stability of the cable shape.
[0026] In this embodiment, if Figure 1 As shown, the number of webs 601 is the same as the number of troughs of the shielding layer 3, and the inner side of the webs 601 abuts against the troughs of the shielding layer 3, making the internal structure of the cable more stable.
[0027] In this embodiment, if Figure 1 As shown, a tensile layer 7 is provided between the foam body 5 and the protective skin 4, so as to enhance the cable's ability to resist stretching and prolong its service life.
[0028] In summary, in this embodiment, the insulator 2 with a wavy outer wall and the wavy shielding layer 3 of this embodiment increase the contact area between the two, which is conducive to improving the adhesion between the layers, thereby reducing the risk of delamination, and also increases the area of the shielding layer 3 itself, thereby improving the shielding effectiveness against electromagnetic interference. In addition, when subjected to external mechanical forces, the wavy shape can better disperse stress at the edge and avoid stress concentration at a single point, which helps to maintain the integrity of the internal structure; the foam body 5 and the skeleton 6 provided can provide additional protection, and the foam body 5 has energy absorption and shock absorption functions, which effectively alleviates the impact of external impact on sensitive components inside the cable. The skeleton 6 provides solid support for the cable, enhances the overall compression, bending and torsion resistance of the cable, and enables it to withstand more mechanical pressure and external force impact.
