The cylindrical housing 110 in this embodiment may be a cylindrical housing, an elliptical cylindrical housing, or a cylindrical housing with other shapes, and the shape of the cylindrical housing 110 is not limited in this embodiment.
The sidewall of the cylindrical housing 110 in this embodiment is provided with three port slots 111 at intervals, and the port slots 111 are used for components in the cavity of the circulator to extend out of the cavity. Fig. 2 shows one shape of the port groove 111, and when implemented, the port groove 111 may have other shapes, which is not limited in this embodiment.
In this embodiment, an annular clamping groove 112 is further disposed on the outer wall of the cylindrical housing 110. The depth of the ring groove 112 is less than or equal to the wall thickness of the expander ring 120, so that the expander ring 120 can be limited. For example, the depth of the ring slot 112 is 0.1 mm. The depth of the ring slot 112 is the width of the step between the outer stepped walls of the cylindrical housing 110.
The side wall of the cylindrical shell 110 in this embodiment is thin, that is, the wall thickness of the side wall of the cylindrical shell 110 is less than a predetermined value. The predetermined value referred to herein is less than the wall thickness of the sidewall of the circulator in the prior art. For example, if the wall thickness of the sidewall of the circulator in the prior art is usually 1mm to 2mm, the predetermined value may be set to 1mm, that is, the thickness of the sidewall of the cylindrical housing 110 in this embodiment is less than or equal to 1 mm.

Optionally, in order to further ensure the hardness of the expansion ring 120, the wall thickness of the expansion ring 120 may be set to be greater than a predetermined value. The predetermined value mentioned here can be obtained from experimental data, for example, 0.5mm, but the embodiment is not limited thereto.
In this embodiment, the expansion ring 120 may be manufactured by turning.
The circulator also includes a cylindrical cover plate 130 positioned within the cavity of the cylindrical housing 110, the cylindrical cover plate 130 having an interference fit with the cylindrical housing 110. In this way, after the cylindrical cover plate 130 is pressed by an external force (press), the cylindrical cover plate 130 can be pressed into the cavity of the cylindrical housing 110, and the cylindrical cover plate 130 does not fall off from the cavity.
In order to facilitate the pressing of the cylindrical cover plate 130 into the cavity, a chamfer may be provided at the junction of the bottom surface and the sidewall of the cylindrical cover plate 130. Since the chamfer makes the diameter of the bottom surface of the cylindrical cover plate 130 smaller, when the diameter of the bottom surface of the cylindrical cover plate 130 is equal to the inner diameter of the cylindrical shell 110, the bottom portion of the cylindrical cover plate 130 can be positioned in the cavity, which facilitates the pressing of the cylindrical cover plate 130 into the cavity.

In one possible embodiment, the functional component 140 may include, from bottom to top: the magnetic field adjusting device comprises a magnet, a magnetic field adjusting sheet, ferrite, a central conductor, ferrite, a magnetic field adjusting sheet and a magnet. In actual implementation, functional component 140 may include more or fewer devices than those described above for functional component 140.
In this embodiment, the height of the expander ring 120 is greater than or equal to the depth of the impact, which is the vertical distance between the bottom surface of the cylindrical cover plate 130 and the top surface of the cylindrical housing 110. In this way, it is ensured that the location of the frictional force generated during the pressing process is always applied in the expansion region of the expansion ring 120, thereby ensuring that the sidewall of the cylindrical shell 110 is not deformed.
In addition, the distance d between the bottom surface of the expander ring 120 and the bottom surface of the cylindrical shell 110 is less than or equal to the thickness of the functional component 140 within the cavity. Thus, when the devices in the functional component 140 need to be reduced, the thickness is reduced, and at this time, the cylindrical cover plate 130 can be continuously pressed downwards from the position of the cylindrical cover plate 130 before the functional component 140 is reduced until the cylindrical cover plate 130 is attached to the functional component 140, so that the problem that the component shakes in the cavity when the position of the cylindrical cover plate 130 is unchanged due to the reduction of the thickness can be solved.
Since different circulators may have different functional components 140 and the heights of the different functional components 140 may be different, i.e., the thicknesses of the functional components 140 are different, the cylindrical housing 110 and the cylindrical cover plate 130 in the present embodiment may be adapted to be used in circulators having different functional components 140.

It should be noted that, when the cylindrical cover plate 130 is pressed into the cylindrical shell 110, the sidewall of the cylindrical shell 110 will be expanded and deformed outwards by the friction force, please refer to fig. 6, and the sidewall of the cylindrical shell 110 will be fixed by the expansion ring 120 and cannot be expanded outwards, so as to avoid the deformation of the sidewall of the cylindrical shell 110.
When the circulator needs to be disassembled, the expansion ring 120 can be taken out first, and then the cylindrical cover plate 130 and the functional component 140 can be taken out. The device can not be damaged in the disassembling process, so that the scrapping of materials can be avoided.
It should be noted that, in the related art, the circulator may be packaged by a screw locking manner, and friction force generated during the screw locking may generate a metal wire, which may cause short circuit or ignition of the device, and increase many unsafe factors, so that a manufacturer may spend a lot of manpower to check the problem of the burr metal wire, but still cannot avoid the problem. According to the embodiment, the cylindrical cover plate 130 can be pressed through external force to package the circulator, and the circulator is prevented from being packaged in a threaded locking mode, so that the problem that the metal wire is checked without manpower is solved, and the labor cost is greatly reduced. In addition, no screw thread is arranged on the cylindrical shell 110 and the cover plate 120, and the cylindrical shell 110 and the cover plate 120 can be produced by adopting a stamping or powder metallurgy process, so that the raw material cost is greatly reduced. In addition, the circulator provided by the embodiment has a simple structure and is high in manufacturability.
The present embodiment also provides an isolator comprising a load and a circulator as above, the load being connected to a pin 141 extending from one of the port slots 111 in the circulator, the pin 141 being a pin of the functional component 140 within the cavity.
