Description

Technical Field

[0001] This utility model relates to the field of circulator technology, and more specifically, to a composite ferrite microstrip circulator. Background Technology

[0002] In modern radar and communication systems, circulators are typically used to achieve unidirectional transmission of electromagnetic signals, which involves the transmission and reception of electromagnetic waves. This allows systems with separate transmitters and receivers to share a single antenna device, thereby greatly reducing the cost and size of the system. In today's pursuit of lightweight and low-cost industrial mass production, the application of circulators is particularly important.

[0003] Based on the gyromagnetic properties of ferrite materials, the transmission characteristics of microwave signals by ferrite change under the influence of a bias magnetic field, allowing the signal to be transmitted in a specific cyclic direction in the microstrip circuit, while reverse transmission is isolated. Most existing circulators adopt a monolithic design with dedicated input and output ports for external connections. While this monolithic design increases strength, it makes maintenance and repair inconvenient. Furthermore, the internal ferrite material's magnetic force weakens over time, making replacement difficult. Therefore, we propose a composite ferrite microstrip circulator. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a composite ferrite microstrip circulator to solve the technical problems of the current integral shell structure being inconvenient to disassemble for maintenance and replacement, and inconvenient to operate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a composite ferrite microstrip circulator, comprising a shell, a fixing block, a top cover, and an external component. The outer side of the shell has an annular array of mounting ports, and the middle of the shell has an assembly port. The bottom of the assembly port has a full ferrite substrate. The shell has positioning ports on both sides, and the front and rear ends of the shell have side interfaces. The positioning ports and side interfaces are connected to the assembly port. The fixing block is slidably inserted into the positioning port, and the external component is slidably inserted into the side interface. A ferrite disc is fixed to the lower end of the top cover, and the ferrite disc is inserted into the assembly port.

[0006] During installation, the ferrite disc is aligned with the assembly port of the outer shell, allowing it to align with the microstrip circuit chip on the all-ferrite substrate. A fixing block is then inserted from the side of the positioning port, its snap-fit ​​fastener connecting to the slot on the side of the positioning port. Simultaneously, the insert bar aligns with the insertion port to achieve a limiting position. The fixing block secures the detachable ferrite disc, facilitating disassembly and maintenance. External circuit connections are achieved via an arch bridge component. The outer ring's outer docking element connects to the rear end of the connecting element, and the connecting element completes the assembly of the external connecting element. The arch bridge component slides downwards and inserts into the side interface, aligning the locking strip with the locking groove. The top cover then presses down to limit the arch bridge component, simultaneously connecting the docking element and the connecting element. This structural design allows for detachable assembly of the circulator's external connection structure, enabling timely maintenance after damage and reducing operational difficulty.

[0007] Preferably, an outer ring is fitted around the outer side of the ferrite disc, and docking elements are distributed in a ring array on the outer side of the outer ring.

[0008] Preferably, the external assembly consists of an arch bridge and a connecting element. The arch bridge is inserted into the side interface, and locking slots are equidistantly provided on the upper side of the arch bridge. The rear end of the connecting element is connected to the docking element.

[0009] Preferably, locking strips are evenly distributed at the upper middle of the side interface. The locking strips are triangular in shape and are slidably inserted into the locking groove.

[0010] Preferably, the fixing block has snap fasteners on both sides, and the snap fasteners snap into the slots on both sides of the positioning port, and the upper inner side of the fixing block is fixed with an insert.

[0011] Preferably, the top cover has openings on both sides, and the fixing block's insert is inserted into the corresponding opening, and the top cover presses down to fit the upper side of the arch bridge component.

[0012] Preferably, a microstrip circuit chip is provided on the upper side of the all-ferrite substrate, and the microstrip circuit chip is located between the all-ferrite substrate and the ferrite wafer.

Then, a fixing block is inserted from the side of the positioning port, and the snap-fit ​​of the fixing block is connected and fixed with the slot on the side of the positioning port. At the same time, the insert strip aligns with the insert to complete the limiting. The fixing block is used to fix the detachable ferrite disc, which is convenient for disassembly and maintenance and easy to operate.

[0015] 2. This utility model also designs an arch bridge component to complete the external circuit connection. The outer ring's outer side docking element and the rear end of the connecting element are inserted together. Then, the external connecting element is assembled through the connecting element.
