Description

Technical Field

[0001] This utility model relates to the field of couplers, specifically to a miniaturized high-isolation coupler. Background Technology

[0002] With the rapid development of modern electronic technology, various electronic devices are constantly moving towards miniaturization and high performance, which also places more stringent requirements on internal electronic components. In many fields such as communications, radar, aerospace, and industrial automation, couplers, as key signal processing and transmission components, directly affect the operational stability and signal quality of the entire system.

[0003] Traditional couplers are ill-suited to current needs and present significant problems. For example, in complex electromagnetic environments, couplers have insufficient isolation, leading to signal crosstalk and high bit error rates in multi-channel communication and DWDM optical networks. This reduces the accuracy of coupler detection and makes it impossible to accurately capture weak signals.

[0004] To address this, a miniaturized, high-isolation coupler is proposed. Utility Model Content

[0005] In view of the problems of the existing couplers mentioned above, this utility model is proposed.

[0006] Therefore, the purpose of this invention is to provide a miniaturized high-isolation coupler, which solves the problem of insufficient isolation in small couplers.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A miniaturized high-isolation coupler includes a housing and a magnetic core. The outer wall of the housing is recessed, and the magnetic core is disposed in the recessed position of the outer wall of the housing. A protective isolation cover is provided on the outer wall of the housing at the recessed position to block the magnetic core. The protective isolation cover includes an upper cover and a lower cover that are magnetically adsorbed. Shielding layers are provided inside both the upper cover and the lower cover.

[0009] Preferably, both ends of the upper cover are fixedly provided with a first magnet block protruding outward, and both ends of the lower cover are fixedly embedded with a second magnet block, and the first magnet block and the second magnet block are magnetically attracted to each other.

[0010] Preferably, the shielding layer is made of multiple stainless steel wire woven mesh layers.

[0011] Preferably, both the inner walls of the upper cover and the lower cover are fixedly provided with heat-conducting plates that are in contact with the magnetic core, and both the upper cover and the lower cover are made of stainless steel.

[0012] Furthermore, the housing adopts a cylindrical structure, and positioning and mounting holes are provided at both ends of the housing.

[0013] Preferably, both the upper and lower covers are hollow structures, and the interiors of the upper and lower covers are filled with thermally conductive helium gas.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model, by setting a protective isolation cover on the outer wall of the shell, the protective isolation cover is composed of an upper cover and a lower cover, and the upper cover and the lower cover are provided with a shielding layer inside, which can improve the protection effect of the magnetic core, avoid the interference of external electromagnetic fields on the magnetic core, and avoid signal crosstalk and bit errors, thereby enabling the coupler to be accurately detected.

[0016] 2. In this utility model, by setting a first magnet block and a second magnet block between the upper cover and the lower cover, the upper cover and the lower cover are placed on the outside of the shell, so that the upper cover and the lower cover wrap around the magnetic core. Then, by magnetic adsorption by the first magnet block and the second magnet block, the upper cover and the lower cover can be stably installed, and disassembly is also relatively convenient.

[0017] 3. In this utility model, by means of heat-conducting plates set on the inner wall of the upper cover and the inner wall of the lower cover, the heat-conducting plates can conduct heat from the surface of the magnetic core and the inside of the shell outward when they come into contact with the magnetic core, thereby improving heat dissipation efficiency.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figure 1-4 The miniaturized high-isolation coupler shown includes a housing 1 and a magnetic core 2. The housing 1 adopts a cylindrical structure, and both ends of the housing 1 are provided with positioning and mounting holes 10. Screws are inserted into the positioning and mounting holes 10 to securely install the housing 1. The outer wall of the housing 1 is designed with a recessed structure. The magnetic core 2 is located in the recessed position of the outer wall of the housing 1. A protective isolation cover 3 is provided on the outer wall of the housing 1 at the recessed position to block the magnetic core 2. The protective isolation cover 3 includes an upper cover 4 and a lower cover 5 magnetically adsorbed. Both the upper cover 4 and the lower cover 5 are provided with a shielding layer 6. The shielding layer 6 is made of multiple stainless steel wire woven mesh layers. The mesh structure provides a more comprehensive shielding effect. The shielding layer 6 can wrap around the magnetic core 2, improve the protection effect of the magnetic core 2, avoid interference from external electromagnetic fields to the magnetic core 2, and enable the coupler to be accurately detected, thereby avoiding signal crosstalk and bit errors.

[0027] In order to enable the upper cover 4 and the lower cover 5 to be installed on or removed from the housing 1, such as Figure 3 As shown, both ends of the upper cover 4 are fixedly provided with outwardly protruding first magnet blocks 7, and both ends of the lower cover 5 are fixedly embedded with second magnet blocks 8. The first magnet blocks 7 and the second magnet blocks 8 are magnetically attracted to each other. When it is necessary to disassemble the upper cover 4 and the lower cover 5, a certain external pulling force is applied to the upper cover 4 and the lower cover 5 by hand, so that the first magnet blocks 7 and the second magnet blocks 8 can be separated.

[0028] Finally, in order to improve heat dissipation performance, such as Figure 2-3 As shown, both the upper cover 4 and the lower cover 5 adopt a hollow structure, and the interior of the upper cover 4 and the lower cover 5 are filled with thermally conductive helium. Helium is an inert gas with good thermal conductivity. The inner sidewalls of the upper cover 4 and the lower cover 5 are both fixedly provided with heat-conducting plates 9 that are in contact with the magnetic core 2. Both the upper cover 4 and the lower cover 5 are made of stainless steel metal covers. When the heat-conducting plates 9 are in contact with the magnetic core 2, they can conduct heat from the surface of the magnetic core 2 and the interior of the shell 1 to the outside, thereby improving heat dissipation efficiency.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
