Description

Technical Field

[0001] The utility model relates to the technical field of circulators, in particular to a microstrip circulator component. Background Art

[0002] A circulator is a multi-port device that transmits the incident wave entering any port to the next port in the order of directions determined by the static bias magnetic field. A circulator, also called an isolator, is a non-reversible device with several ends. Its notable feature is that it can transmit high-frequency signal energy in one direction. It is divided into micro-optical optical fiber and electronic circulator, and has good applications in isolators, duplexers, and reflection amplifiers. The outstanding feature of a circulator, also called an isolator, is that it can transmit high-frequency signal energy in one direction. It controls the transmission of electromagnetic waves in a certain circular direction. This characteristic of unidirectional transmission of high-frequency signal energy is mostly used between the output end and the load of a high-frequency power amplifier, and plays the role of being independent and "isolated" from each other. The load impedance does not affect the working state of the power amplifier when it changes or even when it is open or short-circuited, thereby protecting the power amplifier.

[0003] Please refer to a dual-channel microstrip circulator component disclosed in announcement number CN206639900U. In this patent, it is proposed that "it includes a soft magnetic alloy bottom plate, a ferrite substrate, a metal grounding layer on the lower surface of the ferrite substrate, a microstrip straight-through line circuit and a junction ring microstrip circuit on the upper surface of the ferrite substrate, a permanent magnet providing a bias magnetic field is located above the geometric center of the junction ring microstrip circuit, a dielectric substrate is provided between the permanent magnet and the junction ring microstrip circuit, and the permanent magnet and the junction ring microstrip circuit are electrically isolated by the dielectric substrate; the dual-channel microstrip circulator component not only achieves the purpose of being able to use two antennas at the same time, but also integrates a circulator and a microstrip straight-through line on the same ferrite substrate while ensuring that the size of the original microstrip circulator remains unchanged, and has a simple structure and stable performance". However, the device is not convenient for quick disassembly and installation of the circulator during use, and it is impossible to fix circulators of different sizes, and its flexibility and practicality are low. Therefore, this application proposes another technical solution to solve this problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A microstrip circulator component in this embodiment includes a base plate 1, and an adjustment and fixing mechanism is arranged inside and on the top of the base plate 1.

[0023] In embodiment 1, the adjustment and fixing mechanism includes two threaded rods 2 rotatably connected to the inside of the base plate 1, a knob 3 is fixedly installed on one side of the threaded rod 2, a threaded block 4 is threadedly connected to the outer side of the threaded rod 2, a threaded groove is provided inside the threaded block 4, and the threaded block 4 is threadedly connected to the threaded rod 2 through the threaded groove, so that the threaded block 4 can be easily moved on the outer side of the threaded rod 2.

[0024] Among them, a limit rod 5 slidably connected to the base plate 1 is fixedly installed on the top of the threaded block 4. A sliding groove is opened on the top of the base plate 1. The limit rod 5 is slidably connected to the base plate 1 through the limit groove, which helps to limit the limit rod 5. An installation frame 6 is fixedly installed on the top of the limit rod 5.

[0025] In this embodiment, a sealing plate 7 is hinged on the top of the mounting frame 6, and an inserting plate 8 which is plugged into the right sealing plate 7 is fixedly installed on the left side of the right sealing plate 7. A limiting groove is provided inside the left sealing plate 7, and the inserting plate 8 is fixedly connected to the sealing plate 7 through the limiting groove, which helps to insert the inserting plate 8 into the interior of the sealing plate 7.

[0026] In the second embodiment, a limiting assembly is provided on the top of the left sealing plate 7, and the limiting assembly includes an adjusting box 9 fixedly installed on the top of the left sealing plate 7, a return spring 10 is fixedly installed inside the adjusting box 9, a movable plate 11 is fixedly installed on the bottom of the return spring 10, and sliders 12 slidably connected to the adjusting box 9 are fixedly installed on the left and right sides of the movable plate 11.

[0027] Among them, sliding grooves are opened on the inner walls on the left and right sides of the adjustment box 9, and the slider 12 is slidably connected to the adjustment box 9 through the limit groove, which helps the slider 12 to limit the movable plate 11. The limit assembly also includes a pull rod 13 fixedly installed on the top of the movable plate 11 and slidably connected to the adjustment box 9.

[0028] In this embodiment, the movable plate 11 is fixedly installed on one side away from the pull rod 13 and is plugged into the plug board 8. A slot is provided on the top of the plug board 8, and the pin 14 is fixedly connected to the plug board 8 through the slot, which helps the pin 14 to fix and limit the plug board 8.

[0029] It should be noted that the microstrip circulator assembly, through the setting of the adjustment and fixing mechanism, uses the action of two threaded rods 2 and threaded blocks 4 to drive the two mounting frames 6 to approach each other. When the two mounting frames 6 are close to each other, the pull rod 13 can be pulled, and the pull rod 13 drives the movable plate 11 and the slider 12 to move. At the same time, the movable plate 11 compresses the reset spring 10, so that the pin 14 disengages from the limit groove until the plug plate 8 on the left side of the right sealing plate 7 is inserted into the inside of the right sealing plate 7 to form a sealed space.

[0030] The working principle of the above embodiment is:

[0031] When using the microstrip circulator assembly, the knob 3 is first turned, and the knob 3 drives the threaded rod 2 to rotate. The threaded block 4 on the outside of the threaded rod 2 begins to slide under the limit of the limit rod 5. The movement of the limit rod 5 drives the installation frame 6 to move, so that the two installation frames 6 are separated. The sealing plate 7 is turned to open the closed space. Then the circulator can be placed between the two installation frames 6 and the two sealing plates 7 are closed. Then the knob 3 can be turned in the opposite direction. The knob 3 drives the threaded rod 2 to rotate in the opposite direction, so that the two threaded blocks 4 move closer to each other, and thereby drive the two installation frames 6 to move closer to each other. When the two installation frames 6 are close to each other, the pull rod 13 can be pulled, and the pull rod 13 drives the movable The movable plate 11 and the slider 12 move, and the movable plate 11 compresses the reset spring 10 at the same time, so that the pin 14 disengages from the limit groove until the plug plate 8 on the left side of the right sealing plate 7 is inserted into the inside of the sealing plate 7 on the right to form a sealed space, until the installation frames 6 on both sides fit and clamp the circulator, and finally the pull rod 13 can be loosened, and the reset spring 10 drives the movable plate 11 and the plug pin 14 to move until the plug pin 14 is inserted into the corresponding slot of the plug plate 8, so that the two installation frames 6 and the sealing plate 7 can be fixed to prevent the threaded rod 2 from shaking and deviating, which is helpful to quickly install, close and disassemble the two installation frames 6, greatly improving the flexibility and practicality of the device.
