Embodiment 1

[0037] Please refer to Figure 1-Figure 4 , the present invention provides a wave-absorbing structure of high-efficiency hard wave-absorbing materials, including: a base 1, a number of cones 2 installed on the base 1, a number of grooves 10 are equidistantly arranged on the base 1, The cone 2 is provided with a boss 20 that matches the groove 10; the base 1 and the cone 2 adopt a separate structure, and the boss 20 at the bottom of the cone 2 is directly inserted into the groove during production. In the groove 10, the base 1 and the cone 2 can be quickly connected, which is convenient for production and assembly; when the cone 2 is damaged, it can be replaced quickly without all replacement, effectively saving production resources.

[0038] Specifically, in this embodiment, each of the several cones 2 is connected to its adjacent cone 2 , and a groove 21 is formed at the junction of two adjacent cones 2 . The base 1 is provided with several placement positions 11, the placem...

Embodiment 2

[0050] Please refer to Image 6 , the present invention provides a wave-absorbing structure of high-efficiency hard wave-absorbing materials, including: a base 1, a number of cones 2 installed on the base 1, a number of grooves 10 are equidistantly arranged on the base 1, The cone 2 is provided with a boss 20 that matches the groove 10; the cone 2 is a conical cone 2, the top of the conical cone 2 is rounded, and the several Between the adjacent four conical cones 2 and the base 1, an arc-shaped groove 23 is formed; the assembly mode of the conical cones 2 and the base 1 in the present embodiment is the same as that in embodiment 1 , all adopt a separate structure, which has the advantages of quickly realizing the connection between the base 1 and the conical cone 2, convenient production, assembly and replacement; at the same time, the conical cone 2 is used in this embodiment, and four adjacent conical cones 2 An arc-shaped groove 23 is formed between the base 1, and the co...

Abstract

The invention discloses a wave-absorbing structure of an efficient hard wave-absorbing material and a preparation method thereof, the wave-absorbing structure of the efficient hard wave-absorbing material comprises a base and a plurality of cones installed on the base, the base is provided with a plurality of grooves at equal intervals, and the cones are provided with bosses matched with the grooves; each cone in the plurality of cones is connected with the adjacent cone, and a groove is formed at the joint of every two adjacent cones. The base and the cone are of a separated structure, rapid connection of the base and the cone can be achieved, production and assembly are convenient, connection of the base and the cone is achieved through the boss and the groove, the outer diameter of the boss is larger than the inner diameter of the groove, the boss and the groove extrude each other after connection, connection is tighter, and the cone is effectively prevented from falling off after connection.

Description

technical field [0001] The invention relates to the field of wave-absorbing materials, in particular to a wave-absorbing structure of a high-efficiency hard wave-absorbing material and a preparation method thereof. Background technique [0002] At present, the role of electromagnetic wave absorbing materials in information transmission, electronic devices, microwave radiation protection and other civilian applications is becoming more and more important. With the increase of the working frequency band of electronic equipment, people's demand for broadband absorbing materials is becoming more and more urgent. Improving the absorbing performance of absorbing materials can usually be achieved through the following three aspects: one is to achieve good impedance matching characteristics between the absorbing material and the incident end material, so that electromagnetic energy can enter the material as much as possible to reduce interface reflection; the other is to enhance the ...
