Technical Field

[0001] The present invention relates to the technical field of circulators, and in particular to a circulator and an assembling method thereof. Background Art

[0002] A circulator is a device in a microwave radio frequency system that uses unidirectional transmission of electromagnetic waves. It is generally used between a microwave source and a load to prevent the microwave source from being interfered with by the load direction, thereby ensuring stable operation of the microwave source. In existing circulators, the cover plate and the shell are directly connected, and the shell and the cover plate are made of magnetic metal. The circulator contains magnetic components. Therefore, when assembling the shell and the cover plate, the cover plate is difficult to assemble due to the influence of the magnetic components.

[0013] As a preferred technical solution for the circulator, at least one polygonal hole is provided on the cover plate.

[0014] As an optimal technical solution for the circulator, the magnetic component includes a central conductor, two ferrites, two uniform magnetic plates, a magnet plate and a temperature compensation plate. The two ferrites and the two uniform magnetic plates are respectively arranged on both sides of the central conductor from near to far, the magnet plate is placed on the side of one of the uniform magnetic plates away from the ferrite, and the temperature compensation plate is placed on the side of the magnet plate away from the uniform magnetic plate.

[0034] Embodiment 1

[0035] like Figure 1 and Figure 2As shown, the present embodiment provides a circulator, comprising a first cavity 1, a second cavity 2, a cover plate 3 and a magnetic component 4, wherein the second cavity 2 is provided with an assembly hole 21, the cover plate 3 can be detachably connected in the assembly hole 21, the first cavity 1 and the second cavity 2 are fitted and connected, and the magnetic component 4 is placed between the first cavity 1 and the second cavity 2. When assembling the circulator, the cover plate 3 is first assembled in the assembly hole 21 of the second cavity 2, and then the magnetic component 4 is placed between the first cavity 1 and the second cavity 2, and then the first cavity 1 is connected to the second cavity 2. Since the cover plate 3 is first assembled with the second cavity 2 and then the magnetic component 4 is placed, the cover plate 3 will not be affected by the magnetic component 4 during assembly, and can be assembled quickly, and the cover plate 3 will not generate a large amount of iron filings falling into the inside of the circulator during assembly, so that the performance of the circulator is guaranteed. By setting the second cavity 2, the cover plate 3 can be assembled before the magnetic component 4 is assembled, which reduces the difficulty of assembling the cover plate 3 and solves the problem of iron filings generated when the cover plate 3 is assembled. When the first cavity 1 and the second cavity 2 are assembled, the two are fitted together and then fixed. Therefore, no friction will be generated between the first cavity 1 and the second cavity 2 during assembly, thereby avoiding the generation of iron filings and ensuring the use of the circulator.

[0036] Exemplarily, the first cavity 1 includes a bottom plate 11 and a plurality of protruding columns 12 arranged in a ring on the bottom plate 11, wherein the magnetic component 4 is placed between the plurality of protruding columns 12, and the plurality of protruding columns 12 provide accommodation space for the magnetic component 4, limit the magnetic component 4, and prevent the magnetic component 4 from falling. In the annular device, the bottom surface of the second cavity 2 is fitted with the protruding column 12, and the first cavity 1 and the second cavity 2 are fixedly connected with the protruding column 12 through the fastener 5. Specifically, a first positioning hole is provided on the protruding column 12, a second positioning hole corresponding to the first positioning hole is provided on the second cavity 2, the first positioning hole is provided with an internal thread, and the fastener 5 is provided with an external thread. After the fastener 5 passes through the second positioning hole, it is screwed with the internal thread of the first positioning hole, and finally locked in the first positioning hole. In this embodiment, the fastener 5 can be a bolt. Further, the plurality of protruding columns 12 are arranged in a ring on the bottom plate 11 at intervals from each other, which improves the rationality of the structure of the first cavity 1 and further reduces the risk of the magnetic component 4 falling from between the protruding columns 12.

[0037] Preferably, the protruding column 12 is provided with a first avoidance groove 121, and a fixing hole 122 is provided in the first avoidance groove 121. At the same time, a second avoidance groove is provided on the second cavity 2, and the second avoidance groove is opposite to the first avoidance groove 121. In this way, after the circulator is assembled, the staff can fix the circulator through the fixing hole 122 and the fixing piece. The provision of the first avoidance groove 121 and the second avoidance groove makes it easier for the staff to assemble the fixing piece, giving the staff operating space. Bolts can be selected for the fixing piece.

[0038] Preferably, the protruding column 12 and the bottom plate 11 are an integrated structure, which not only facilitates the processing of the first cavity 1, but also makes the overall structure of the first cavity 1 more stable, further ensures the stability of the circulator structure, and improves the service life of the circulator.

[0039] Regarding the assembly of the cover plate 3 and the assembly hole 21, illustratively, an internal thread is provided in the assembly hole 21, and an external thread is provided on the cover plate 3, and the internal thread and the external thread are screwed together to realize that the cover plate 3 can be detachably connected to the assembly hole 21. Preferably, at least one polygonal hole 31 is provided on the cover plate 3, so that the cover plate 3 can be rotated by a corresponding polygonal cylindrical tool to realize the rapid assembly or disassembly of the cover plate 3 and the assembly hole 21, further reducing the difficulty of assembly of the cover plate 3 and the assembly hole 21 by the staff. Regarding the polygonal hole 31, a quadrilateral hole, a pentagonal hole or a hexagonal hole can be selected, and the specifications of the polygonal hole 31 are not specifically limited here.

[0040] Exemplarily, the magnetic component 4 includes a central conductor 40, two ferrites 41, two uniform magnetic plates 42, a magnet plate 43 and a temperature compensation plate 44, wherein the two ferrites 41 and the two uniform magnetic plates 42 are respectively arranged on both sides of the central conductor 40 from near to far, and the ferrites 41 are respectively placed on both sides of the central conductor 40 to avoid the heat generated by the two ferrites 41 from being concentrated when the circulator is working, and to avoid the local temperature being too high during the operation of the circulator, thereby affecting the life of the circulator. The magnet plate 43 is placed on the side of one of the uniform magnetic plates 42 away from the ferrite 41, and the temperature compensation plate 44 is placed on the side of the magnet plate 43 away from the uniform magnetic plate 42. Specifically, the central conductor 40 is used to transmit signals, the magnet plate 43 is used to provide an external bias magnetic field, the uniform magnetic plate 42 is used to make the external bias magnetic field uniform, and the ferrite 41 is used to provide a rotating magnetic field. The temperature compensation sheet 44 is used to provide temperature compensation for other components inside the circulator. Specifically, when the circulator is working, the temperature of the circulator as a whole will change, thereby affecting the parameters of the circulator. The setting of the temperature compensation sheet 44 can ensure that the temperature of the circulator is in a stable range, thereby ensuring the stability of the parameters of the circulator, and further improving the stability of the performance of the circulator when it is working. In this embodiment, the functions of the central conductor 40, the ferrite 41, the uniform magnetic sheet 42 and the magnet sheet 43 belong to the common knowledge in the field of circulators, and will not be described in detail here.

[0041] Furthermore, the center conductor 40 includes a plurality of legs 401, and placement grooves are formed between the protruding columns 12, and the plurality of legs 401 are correspondingly placed in the plurality of placement grooves. In this way, the first cavity 1 is not only simple in structure, but also can realize the rapid and stable placement of the center conductor 40, further improving the rationality of the circulator design. At the same time, after the circulator is assembled, the external air can flow into the interior of the circulator through the position of the placement groove, realizing the internal air circulation of the circulator, and the internal temperature of the circulator during operation is further reduced by the circulation of air, so that the safety of the use of the circulator is further guaranteed.
