As used herein, the singular form is intended to also include the plural form, unless the context clearly indicates otherwise.

[0041] Example

[0042] The embodiment of the present invention discloses a ring isolator, such as Figure 1-5As shown, it includes: a cavity 1, an insulating ring 2, a central conductor 3, a cover plate 4, and a central stacking assembly 5; wherein,

[0043] The cavity 1 is a hollow structure with an opening at the top, and a plurality of mounting grooves 11 are evenly arranged on the peripheral wall of the cavity 1, and each mounting groove 11 extends from the top of the cavity 1 to the bottom of the cavity 1;

[0044] The insulating ring 2 is provided with a plurality of protrusions 21; the number of the protrusions 21 is the same as the number of the mounting grooves 11, and the shape of the protrusions 21 matches the shape of the mounting grooves 11, and the position of the protrusions 21 on the insulating ring 2 corresponds to the position of the mounting grooves 11 on the cavity 1, so that when the insulating ring 2 is installed in the cavity 1, each of the protrusions 21 is fixed and clamped by the mounting grooves 11;

[0045] Each of the protrusions 21 is provided with a pin 211; the central conductor 3 is provided with a plurality of connecting portions 31; the number of the connecting portions 31 is consistent with the number of the protrusions 21; each of the connecting portions 31 is provided with a connecting hole 311; the connecting hole 311 matches the pin 211, and the insulating ring 2 is connected to the central conductor 3 by connecting the pin 211 with the connecting hole 311 on the connecting portion 31;

[0046] The cover plate 4 is fixedly connected to the cavity 1 to form a receiving cavity; the receiving cavity is fixedly connected to the central stacking assembly 5 , the central conductor 3 and the insulating ring 2 .

[0047] Specifically, in this solution, an integrated insulating ring 2 is provided. During installation, the insulating ring 2 can be directly clamped in the installation groove 11 of the cavity 1, which is convenient and simple to install and can effectively reduce the installation time.

[0048] A pin 211 for connecting the center conductor 3 is provided on the insulating ring 2, so that it is no longer necessary to provide a connecting structure on the cavity 1, thereby reducing the structural complexity of the cavity 1 and reducing the processing amount of the cavity 1. The cavity 1 is the most important processing part of the annular isolator, so the processing amount of the entire annular isolator is also reduced, thereby improving the processing efficiency and the production efficiency, which is conducive to meeting the large-scale production needs of the annular isolator.

[0049] In addition, since the insulating ring 2 is an integral ring, the pins 211 arranged thereon can effectively ensure the flatness of each pin 211, thereby reducing the manual adjustment process and facilitating the installation and normal operation of the entire ring isolator. Figure 1-5As shown, there can be two stitching pins 211. Based on an integrated annular insulating ring 2, the coplanarity between the three stitching pins and the bottom surface of the cavity can be guaranteed, which can effectively improve the disadvantage of insufficient coplanarity with the cavity floor caused by the need to install the three independent stitching pins separately.

[0050] In a specific embodiment, the number of mounting grooves 11, protrusions 21, stitching pins 211, connecting parts 31, and connecting holes 311 are the same, and can be adjusted as needed, for example, to 3, 4, 5, etc., and in a specific application scenario, based on balancing costs and processing needs, the number of mounting grooves 11 is 3.

[0051] In a specific embodiment, in order to facilitate installation, the insulating ring 2 and the central conductor 3 can be conveniently placed in the installation grooves 11 of the cavity 1 , and the installation grooves 11 are evenly distributed on the peripheral wall of the cavity 1 .

[0052] In a specific embodiment, for the purpose of insulation and processing, the insulating ring 2 is specifically a plastic ring.

[0053] By providing the plastic ring, the insulating ring 2 can have good insulating properties and be easy to process. In addition, when the insulating ring 2 is changed in size, it can also be easily processed and adjusted.

[0054] In a specific embodiment, the central stacking assembly 5 may be an existing stacking assembly in the annular isolation area.

[0055] In a specific embodiment, the central stacking assembly 5 may include a central first stacking assembly and a central second stacking assembly; wherein the central first stacking assembly is fixed between the cover plate 4 and the central conductor 3; and the central second stacking assembly is fixed between the central conductor 3 and the insulating ring 2.

[0057] Thus, the annular isolator includes, from the cover plate 4 to the center conductor 3, from top to bottom, the cover plate 4, the first uniform magnetic plate 51, the second uniform magnetic plate 52, the first temperature patch plate 53, the second temperature patch plate 54, the samarium cobalt plate 55, the first shielding plate 56, the first ferrite 57, and the center conductor 3; specifically, the first uniform magnetic plate 51, the second uniform magnetic plate 52, the first temperature patch plate 53, the second temperature patch plate 54, the samarium cobalt plate 55, the first shielding plate 56, and the first ferrite 57 are cylindrical with a certain thickness; wherein, the shape and size of the first uniform magnetic plate 51 and the second uniform magnetic plate 52 can be consistent; the shape and size of the first temperature patch plate 53 and the second temperature patch plate 54 can be consistent;

[0058] In addition, if Figure 2 As shown, the central second stacking component includes, from top to bottom, a second ferrite 58 , a second shielding sheet 59 , and a strontium calcium sheet 510 .

[0060] Specifically, in one embodiment, in order to facilitate installation, the cross-section of the central stacking component 5 (such as the first shim plate 51 , the first shielding plate 56 , etc.) is circular.

[0061] In a specific embodiment, Figure 1 as well as Figure 2 As shown, the cover plate 4 is provided with an edge protrusion 41 , and the cover plate 4 is fixedly connected to the cavity 1 via the edge protrusion 41 .

[0062] Specifically, the edge protrusion 41 is used to be fixedly connected to the cavity 1, thereby achieving that the entire cover plate 4 is fixedly connected to the entire cavity 1

[0063] In a specific embodiment, the cavity 1 is an integrated metal structure; Figure 1-5 As shown,

[0064] A plurality of claws 12 are disposed on the top of the cavity 1 ; the cavity 1 is fixedly connected with the cover plate 4 by fixing the edge protrusions 41 of the cover plate 4 through the claws 12 .

[0065] The specific clamping claw 12 is made of metal, and the specific installation is to squeeze the clamping claw 12 by pressure so that the clamping claw 12 is bent and bent to the extent of being close to the edge protrusion 41 on the cover plate 4, thereby achieving a fixed connection between the cover plate 4 and the cavity 1.

[0066] Thus, an embodiment of the present invention proposes an annular isolator, comprising: a cavity 1, an insulating ring 2, a central conductor 3, a cover plate 4, and a central stacking assembly 5; wherein the cavity 1 is a hollow structure with an opening at the top, and a plurality of mounting grooves 11 are evenly arranged on the peripheral wall of the cavity 1, and each of the mounting grooves 11 extends from the top of the cavity 1 to the bottom of the cavity 1; the insulating ring 2 is provided with a plurality of protrusions 21; the number of the protrusions 21 is the same as the number of the mounting grooves 11, and the shape of the protrusions 21 matches the shape of the mounting grooves 11, and the position of the protrusions 21 on the insulating ring 2 corresponds to the position of the mounting grooves 11 on the cavity 1, so that the insulating ring 2 is installed in the cavity 1, each of the protrusions 21 is fixedly clamped by the installation groove 11; each of the protrusions 21 is provided with a pin 211; the center conductor 3 is provided with a plurality of connecting parts 31; the number of the connecting parts 31 is consistent with the number of the protrusions 21; each of the connecting parts 31 is provided with a connecting hole 311; the connecting hole 311 matches the pin 211, and the insulating ring 2 is connected to the center conductor 3 by connecting the pin 211 with the connecting hole 311 on the connecting part 31; the cover plate 4 is fixedly connected to the cavity 1 to form a receiving cavity; the receiving cavity is fixedly connected to the center stacking assembly 5, the center conductor 3 and the insulating ring 2.
