Description

Technical Field

[0001] This application belongs to the field of communication technology, and in particular relates to a resonator and filter. Background Technology

[0002] In some cases, the resonator includes a cover plate, a fixed plate, and an adjusting member. The cover plate includes a deformable portion and a fixed portion located on the outer periphery of the deformable portion. The fixed plate is fixed to the fixed portion, and a threaded hole passes through the center of the fixed plate. The end of the adjusting member away from the deformable portion is threadedly connected to the threaded hole, while the end of the adjusting member closer to the deformable portion is axially and rotatably connected to the deformable portion. Based on this, the resonant frequency can be adjusted by rotating the adjusting member to move axially and causing the deformable portion to deform axially. However, existing technologies require additional retaining rings or limiting caps to be fitted around the outer periphery of the adjusting member, and the retaining rings or limiting caps must be connected and engaged with the deformable portion to achieve axially and rotatably connected to the deformable portion. This complicates the installation method and connection operation of the adjusting member and increases the number of parts. Summary of the Invention

[0004] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0005] In a first aspect, a resonator is provided, comprising:

[0006] The cover plate has a deformable part that can be deformed under force, and a fixing part provided on the outer periphery of the deformable part, wherein the deformable part is provided with a threaded hole;

[0007] A support member is separately connected to the fixed part and spaced apart from the deformable part; the support member is provided with a through connection hole.

[0008] An adjusting component, one end of which is threaded to the threaded hole, and the other end of which is axially limited and rotatably connected to the connecting hole.

[0009] In some embodiments, the threaded hole is formed on the side of the deformed portion facing the support member, and the threaded hole is a blind hole.

[0010] In some embodiments, the deformable portion is provided with a connecting boss, and the threaded hole is formed on the connecting boss.

[0011] In some embodiments, the support member includes a support portion and a bending portion, the bending portion being connected to the outer periphery of the support portion and bent toward the side closer to the cover plate, and the bending portion being connected and fixed to the fixing portion.

[0012] In some embodiments, the support member is connected to the end face of the fixing portion facing the support member.

[0013] In some embodiments, the support member is welded to the fixing part.

[0014] In some embodiments, the adjusting member includes a main body and a connecting portion connected to one end of the main body facing away from the deformable portion, the connecting portion being engaged with the connecting hole.

[0015] In some embodiments, the connecting portion includes a connecting section, a stop protrusion, and a snap-fit ​​protrusion. The connecting section passes through the connecting hole, the stop protrusion protrudes outward from one end of the connecting section and stops at one side of the connecting hole, and the snap-fit ​​protrusion protrudes outward from the other end of the connecting section and snaps onto the other side of the connecting hole.

[0016] In some embodiments, a cut-off groove is provided on the end side of the connecting segment near the buckle protrusion.

[0017] In some embodiments, the adjusting member has an operating part at one end facing away from the deformable portion.

[0018] In some embodiments, the buckle protrusion is located at the end of the connecting section away from the main body, and the cut-off groove is an operating part.

[0019] In some embodiments, the end of the adjusting member facing away from the deformed portion is bent to form a flange, and the flange stops at the edge of the connecting hole.

[0020] In some embodiments, the deformable part is a soft aluminum alloy material part;

[0022] And / or, the adjusting element is made of steel.

[0023] In some embodiments, the cover plate is an integral single-layer cover plate;

[0024] Alternatively, the cover plate is a double-layer cover plate, the cover plate includes a first plate and a second plate, the second plate has the fixing part, the first plate is stacked on the side of the second plate away from the support member, and has the deformable part.

[0025] Secondly, a filter is provided, including the resonator provided in the embodiments of this application.

[0026] The beneficial effects of the resonator provided in this application are as follows:

[0027] The resonator provided in this application embodiment can achieve the function of tuning (i.e., adjusting the resonant frequency) by threading the adjusting member to the deformable part and rotatably connecting it to the support member with axial limitation. The tuning difficulty is small, and the tuning operation is simple, stable, and controllable. Moreover, compared with the prior art, this embodiment transfers the threaded connection to the deformable part, so that the adjusting member can be directly threaded to the deformable part without the need for other components such as snap rings or limiting caps to connect and cooperate with the deformable part. This embodiment transfers the axially limited rotatable connection to the support member, so that the connecting hole can be directly set as a through hole without considering the electrical performance of the resonator (because the connecting hole will not affect the sealing of the resonant cavity or the electrical performance of the resonator). This allows the adjusting member to be directly inserted into the through connecting hole and limited to cooperate with the connecting hole to quickly achieve axially limited rotatable connection without the need for other components such as snap rings or limiting caps to achieve axial limitation. This simplifies the connection between the adjusting component and the deformable part, and between the adjusting component and the supporting component. It also simplifies the installation and connection of the adjusting component, reduces the structure of the resonator, and minimizes the number of components, thus facilitating the miniaturization and weight reduction of the resonator.

Detailed Implementation

[0039] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clear, the application will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application. Unless otherwise specified, all embodiments and optional embodiments of this application can be combined to form new technical solutions. Unless otherwise specified, all technical features and optional technical features of this application can be combined to form new technical solutions.

[0040] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In this application, "central axis" refers to a line that passes through the geometric center of the corresponding structure.

[0044] In this application, "axial" refers to the direction of extension of the central axis of the corresponding structure, "radial" refers to any direction of the corresponding structure that passes through and is perpendicular to the central axis, and "circumferential" refers to the direction of circumference of the outer circumference of the corresponding structure.

[0045] In some cases, the resonator includes a cover plate, a fixed plate, and an adjusting member. The cover plate includes a deformable portion and a fixed portion located on the outer periphery of the deformable portion. The fixed plate is fixed to the fixed portion, and a threaded hole passes through the center of the fixed plate. The end of the adjusting member away from the deformable portion is threadedly connected to the threaded hole of the fixed plate, while the end of the adjusting member closer to the deformable portion is axially limited and rotatably connected to the deformable portion. Based on this, by rotating the adjusting member, it can move axially. Since the adjusting member is axially limited and rotatably connected to the deformable portion, during the axial movement of the adjusting member, the deformable portion can be deformed axially, thereby adjusting the resonant frequency.

[0046] To achieve the goal of "the adjusting component being rotatably connected to the deformable part with axial limiting", the existing technology provides two solutions:

[0047] Existing technology (1): The deformable part has a through hole, and the adjusting member is inserted through the through hole. The end of the adjusting member that extends into the resonator is provided with a limiting boss. The limiting boss limits and stops at one side of the hole. A retaining spring is also fixedly sleeved on the outer periphery of the adjusting member. The retaining spring limits and stops at the other side of the hole. Based on this, the adjusting member can be axially limited relative to the deformable part through the limiting boss and the retaining spring, and has rotational freedom.

[0048] Prior art (II): The deformable part has a groove on the side facing the fixed plate, and the adjusting part has a limiting boss at the end near the deformable part. The limiting boss is installed in the groove, and the adjusting part is also fitted with a limiting cap at the end near the deformable part. The outer periphery of the limiting cap is interference-fitted with the groove wall, and the limiting cap also presses against the side of the limiting boss facing away from the bottom of the groove. Based on this, the adjusting part can axially limit the limiting boss of the limiting cap and the bottom of the groove, thereby achieving axial limitation relative to the deformable part and having rotational freedom.

[0049] However, existing technologies require additional snap rings or limiting caps to be fitted around the outer periphery of the adjusting component, and the snap rings or limiting caps must be connected and fitted with the deformed part (especially since the actual size of the resonator is very small, the connection and fit between the snap rings or limiting caps and the deformed part will be very difficult) in order to enable the adjusting component to be axially limited and rotatably connected to the deformed part. This makes the installation method and connection operation of the adjusting component complicated and increases the number of parts.

[0050] Furthermore, existing technologies cause axial movement of the adjusting component during the application of force. This necessitates that the adjusting component have a certain length and protrude beyond the fixed plate, both in design and during debugging. The significant protrusion of the adjusting component hinders the miniaturization of the resonator's overall shape. Moreover, the axial freedom of the adjusting component protruding from the fixed plate also easily leads to accidental contact and collisions, which can damage the adjusting component, alter tuning parameters, and affect the resonator's normal operation.

[0051] The embodiments provided in this application will solve the above problems.

[0052] The specific implementation of this application will be described in detail below with reference to specific embodiments:

[0053] Please see Figure 1 , Figure 2 , Figure 3 Some embodiments of this application provide a resonator including a cover plate 11, a support member 20, and an adjusting member 30. The cover plate 11 has a deformable portion 111 that can be deformed under force, and a fixed portion 112 provided on the outer periphery of the deformable portion 111. The deformable portion 111 is provided with a threaded hole 1111. The support member 20 is separately connected to the fixed portion 112 and spaced apart from the deformable portion 111. The support member 20 is provided with a through connecting hole 211. One end of the adjusting member 30 is threadedly connected to the threaded hole 1111, and the other end of the adjusting member 30 is axially limited and rotatably connected to the connecting hole 211.

[0054] It should be noted that the resonator includes a resonator housing 10, and the resonator housing 10 has a resonant cavity 13 inside. The resonator housing 10 can provide shielding to prevent signal leakage.

[0055] One side of the resonator housing 10 is a cover plate 11. In practical applications, the resonator can be placed with the cover plate 11 facing upwards, or with the cover plate 11 facing left, right, forward, or backward. Furthermore, the shape, size, and material of the resonator housing 10 can be flexibly configured as needed.

[0056] The cover plate 11 has a deformable portion 111 and a fixed portion 112. The fixed portion 112 is disposed around the outer periphery of the deformable portion 111 and is used to connect and fix it to other parts of the resonator housing 10 (which may be referred to as the cavity 12). The thickness of the deformable portion 111 is less than the thickness of the fixed portion 112, and the thickness of the deformable portion 111 is relatively thin. The deformable portion 111 can be deformed by force towards the side closer to the resonant cavity 13, or it can be deformed by force away from the resonant cavity 13, so as to adjust the resonant frequency. The deformable portion 111 can be integrally formed with the fixed portion 112, or the deformable portion 111 can be separately connected to the fixed portion 112; when the deformable portion 111 and the fixed portion 112 are separately connected, the deformable portion 111 can be stacked with the fixed portion 112 and connected to the side of the fixed portion 112 facing the resonant cavity 13, or the deformable portion 111 can be connected to the inner peripheral surface of the fixed portion 112. The deformable part 111 can be made of a deformable ductile metal material that does not automatically spring back after deformation.

[0057] It should also be noted that the support member 20 is formed separately from the cover plate 11. The support member 20 is located on the outer side of the cover plate 11 facing away from the resonant cavity 13. The support member 20 is separately connected to and fixed relative to the fixing part 112 to stabilize the installation position and installation state of the support member 20 relative to the fixing part 112. The support member 20 can be connected and fixed to the fixing part 112 by, but is not limited to, welding, pressing, snap-fitting, bonding, screw connection, plug-in connection, threaded connection, etc.

[0058] At least a portion of the support member 20 is provided corresponding to the deformable part 111, and they are spaced apart. The space between the support member 20 and the deformable part 111 can reserve deformation space for the deformable part 111.

[0059] It should also be noted that the deformable part 111 has a threaded hole 1111 on the side facing the support member 20, and the wall of the threaded hole 1111 has internal threads. The outer peripheral surface of the adjusting member 30 near the end of the deformable part 111 has external threads, and the end of the adjusting member 30 near the deformable part 111 is threaded into the threaded hole 1111 of the deformable part 111. The threaded hole 1111 can be either a blind hole or a through hole. When the threaded hole 1111 is a through hole, to prevent the signal in the resonant cavity 13 from leaking through the threaded hole 1111, the adjusting member 30 can be made of metal; of course, if the performance requirements are not high, the adjusting member 30 can also be made of non-metallic material. When the threaded hole 1111 is a blind hole, the adjusting member 30 can be made of either metal or non-metallic material.

[0060] The support member 20 is provided with a connecting hole 211, which passes through the support member 20 and is aligned with the threaded hole 1111. The connecting hole 211 is a smooth hole with a smooth wall. The end of the adjusting member 30 away from the deformable part 111 is axially limited and rotatably connected to the connecting hole 211, that is, the adjusting member 30 has rotational freedom in the connecting hole 211, and the axial movement of the adjusting member 30 relative to the support member 20 is restricted. Specifically, the adjusting member 30 may be restricted to axial movement both in the direction away from the resonant cavity 13 and in the direction close to the resonant cavity 13 (i.e., the adjusting member 30 cannot move axially at all), or it may be restricted only to axial movement in the direction away from the resonant cavity 13, or it may be restricted only to axial movement in the direction close to the resonant cavity 13.

[0061] Based on this, when the adjusting member 30 is restricted to axial movement in the direction away from the resonant cavity 13, by rotating the adjusting member 30, it tends to move in the direction away from the resonant cavity 13. Since the adjusting member 30 cannot move axially in the direction away from the resonant cavity 13, based on the threaded connection between the adjusting member 30 and the deformable part 111, the adjusting member 30 will cause the deformable part 111 to deform towards the resonant cavity 13, thereby achieving adjustment of the resonant frequency. When the adjusting member 30 is restricted to axial movement in the direction close to the resonant cavity 13, by rotating the adjusting member 30, it tends to move in the direction close to the resonant cavity 13. Since the adjusting member 30 cannot move axially in the direction close to the resonant cavity 13, based on the threaded connection between the adjusting member 30 and the deformable part 111, the adjusting member 30 will cause the deformable part 111 to deform towards the direction away from the resonant cavity 13, thereby achieving adjustment of the resonant frequency. Therefore, the resonant frequency can be adjusted bidirectionally when the adjusting member 30 is restricted to axial movement both away from the resonant cavity 13 and towards the resonant cavity 13 (i.e., the adjusting member 30 cannot move axially at all).

[0062] Therefore, the resonator provided in this application embodiment can achieve the function of tuning (i.e. adjusting the resonant frequency) by threading the adjusting member 30 to the deformable part 111 and rotatably connecting it to the support member 20 in an axially limited manner. Moreover, the tuning difficulty is small, and the tuning operation is simple, stable and controllable. Furthermore, compared to the prior art, this embodiment transfers the threaded connection to the deformable part 111, allowing the adjusting member 30 to be directly threaded to the deformable part 111 without the need for other components such as snap rings or limiting caps to connect and cooperate with the deformable part 111. This embodiment also transfers the axially limited rotatable connection to the support member 20, allowing the connecting hole 211 to be directly set as a through hole without considering the electrical performance of the resonator (because the connecting hole 211 will not affect the sealing of the resonant cavity 13 or the electrical performance of the resonator). This allows the adjusting member 30 to be directly inserted into the through connecting hole 211 and limited to cooperate with the connecting hole 211 to quickly achieve an axially limited rotatable connection without the need for other components such as snap rings or limiting caps to achieve axial limitation. Therefore, the connection operation between the adjusting member 30 and the deformable part 111, and between the adjusting member 30 and the support member 20 can be simplified. The installation method and connection operation of the adjusting member 30 can be simplified, the structure of the resonator can be simplified, the number of resonator parts can be reduced, and the miniaturization and weight reduction of the resonator can be facilitated.

[0063] Furthermore, since the adjusting member 30 is axially limited by the support member 20, the axial movement of the adjusting member 30 is restricted. In some embodiments, the adjusting member 30 may not move axially. Therefore, the portion of the adjusting member 30 protruding from the support member 20 does not need to be too long, or the adjusting member 30 may not even protrude from the support member 20. In this way, the protruding size of the adjusting member 30 is small, which can help reduce the overall size of the resonator and facilitate the miniaturization of the resonator. In addition, it can reduce the risk of the adjusting member 30 being accidentally touched, collided with, or damaged, improve the stability and effectiveness of the tuning index, and improve the reliability of the adjusting member 30 and the resonator.

[0064] like Figure 4 As shown, in one possible implementation, the resonant cavity 13 can accommodate a resonant rod 40. The resonant rod 40 is connected and fixed to a plate on the resonator housing 10 opposite to the cover plate 11, and is spaced apart from the deformable portion 111. In this case, the deformable portion 111 can be deformed under force to change the distance between the deformable portion 111 and the resonant rod 40, thereby adjusting the capacitance between the deformable portion 111 and the resonant rod 40, and thus adjusting the resonant frequency.

[0065] like Figure 5As shown, in another possible embodiment, the resonant cavity 13 can accommodate the resonant rod 40. The resonant rod 40 is connected and fixed to the deformable portion 111. In this case, the deformable portion 111 can be deformed under force to change the distance between the end of the resonant rod 40 away from the deformable portion 111 and the corresponding inner wall of the resonator housing 10, thereby adjusting the capacitance between the end of the resonant rod 40 away from the deformable portion 111 and the corresponding inner wall of the resonator housing 10, thereby adjusting the resonant frequency.

[0066] The resonant rod 40 can be connected and fixed to the resonator housing 10 by, but is not limited to, integral connection, welding, screw fastening, threaded connection, riveting, crimping, snap-fit, etc. The resonant rod 40 can be a metal resonant rod, a ceramic dielectric resonant rod, or a dielectric resonant rod of other materials; the resonant rod 40 can be a hollow resonant rod or a solid resonant rod; the resonant rod 40 can have a resonant disk or not; the resonant disk can have a flange or not; the resonant rod 40 can be a round rod, a polygonal rod, an irregularly shaped rod, a sheet metal resonant rod, or other resonant rod shapes, etc.

[0067] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the threaded hole 1111 is formed on the side of the deformed portion 111 facing the support member 20, and the threaded hole 1111 is a blind hole. That is, the threaded hole 1111 does not penetrate the deformed portion 111.

[0068] By adopting the above scheme, the cover plate 11 can work in conjunction with other parts of the resonator housing 10 (i.e., cavity 12) to fully and reliably seal the resonator cavity 13, thereby improving the sealing performance of the resonator cavity 13. This optimizes the shielding function of the resonator housing 10 and reduces the risk of signal leakage from the threaded hole 1111. Furthermore, it reduces the risk of impurities such as burrs, debris, and dust seeping into the resonator through the gap between the adjusting member 30 and the threaded hole 1111, thus maintaining the electrical performance, intermodulation, and power performance of the resonator.

[0069] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the deformable part 111 is provided with a connecting boss 1112, and a threaded hole 1111 is formed on the connecting boss 1112.

[0070] It should be noted that the connecting boss 1112 can protrude from the deformable part 111 on the side facing the support member 20, and the thickness of the area where the connecting boss 1112 is located is greater than the thickness of other areas of the deformable part 111. A threaded hole 1111 is formed on the connecting boss 1112, allowing the depth of the threaded hole 1111 to be extended as needed. The connecting boss 1112 can be integrally formed on the deformable part 111 or separately connected to the deformable part 111. The separate connection method can be, but is not limited to, bonding or welding. The shape and size of the connecting boss 1112 can be set as needed.

[0071] By adopting the above solution, a connecting boss 1112 can be provided on the deformable part 111, and a threaded hole 1111 can be opened on the connecting boss 1112, so as to extend the depth of the threaded hole 1111 as needed. Based on this, it is beneficial to expand the adjustable range of the connection length between the threaded hole 1111 and the adjusting member 30, thereby expanding the deformable amount of the deformable part 111 and expanding the adjustable range of the resonant frequency.

[0072] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the support member 20 includes a support portion 21 and a bending portion 22. The bending portion 22 is connected to the outer periphery of the support portion 21 and is bent towards the side close to the cover plate 11. The bending portion 22 is connected and fixed to the fixing portion 112.

[0073] It should be noted that the support part 21 and the deformable part 111 are correspondingly and spaced apart, and the connecting hole 211 is provided in the support part 21. The bent part 22 is bent and connected to the outer periphery of the support part 21. The bent part 22 is bent relative to the support part 21 towards the side closer to the cover plate 11, so that the support member 20 is a cap shape with a flange. The bent part 22 is connected and fixed to the fixed part 112, that is, the bent part 22 is connected to the fixed part 112 and fixed relative to the fixed part 112. The connection method can be, but is not limited to, welding, pressing, snap-fitting, bonding, screw connection, plug-in connection, threaded connection, etc.

[0074] By adopting the above solution, the support member 20 can be connected and fixed to the fixing part 112 through the bent portion 22, which is bent relative to the support part 21 towards the side closer to the cover plate 11. Based on this, the structure of the support member 20 can be optimized, and the connection between the support member 20 and the fixing part 112 can be improved. Furthermore, the support member 20 can also have a certain amount of internal space, which can provide sufficient deformation space for the deformation part 111, thereby correspondingly reducing the thickness of the cover plate 11 and correspondingly reducing the weight of the resonator, which is beneficial to the miniaturization and weight reduction of the resonator.

[0075] This embodiment is particularly suitable for use in conjunction with the embodiment in which the "deformable part 111 is provided with a connecting boss 1112". When the deformable part 111 is provided with a connecting boss 1112, the deformation space can be mainly provided by the bending part 22, without the cover plate 11 being responsible for providing the deformation space. In this case, the height of the connecting boss 1112 can be flush with the height of the fixing part 112, which is beneficial for the machining and forming of the connecting boss 1112, and the machining can be completed with only one step of cutting.

[0076] Of course, in other embodiments, the support member 20 may be a flat plate or a plate with steps.

[0077] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the support member 20 is connected to the end face of the fixing part 112 facing the support member 20 (i.e., the outer surface of the fixing part 112 facing away from the resonant cavity 13).

[0078] By adopting the above solution, the support member 20 can be connected to the end face of the fixing part 112 facing the support member 20, that is, connected to the outer surface of the fixing part 112 facing away from the resonant cavity 13, instead of being connected to the outer peripheral surface of the fixing part 112. Based on this, the support member 20 can be conveniently and reliably connected and fixed to the fixing part 112 according to its installation position, improving the convenience and reliability of the connection between the support member 20 and the fixing part 112. Furthermore, since the support member 20 does not need to extend to the periphery of the fixing part 112 before connecting to its outer peripheral surface, it is beneficial to reduce the overall size of the support member 20, which in turn is beneficial to reduce the overall size of the resonator, thus contributing to the miniaturization and weight reduction of the resonator.

[0079] This embodiment is particularly suitable for use in conjunction with the embodiment in which "the support member 20 includes a support portion 21 and a bent portion 22". When the bent portion 22 of the support member 20 is connected to the end face of the fixing portion 112 facing the support member 20, the space enclosed by the bent portion 22 and the support portion 21 can be sufficiently preserved without being occupied by the fixing portion 112. This allows for a larger space to be enclosed between the support member 20 and the cover plate 11, thereby providing a larger deformation space for the deformation portion 111 and a larger accommodating space for the connecting boss 1112.

[0080] Of course, in other embodiments, the support member 20 may be connected to the outer peripheral surface of the fixing part 112; or, the fixing part 112 may be provided with a stepped groove, and the support member 20 may be connected to the groove wall or the bottom of the stepped groove.

[0081] Please see Figure 1 , Figure 2 , Figure 3In some embodiments of this application, the support member 20 is welded to the fixing part 112. That is, the support member 20 and the fixing part 112 are welded at their contacting edges to achieve connection and fixation. The welding can be laser welding, ultrasonic welding, etc. Continuous welding can be used to fix the support member 20 and the fixing part 112 together.

[0082] By adopting the above solution, the support member 20 can be conveniently, quickly, reliably and firmly connected and fixed to the fixing part 112 of the cover plate 11 through welding, thereby improving the connection convenience, connection reliability and connection stability between the support member 20 and the fixing part 112.

[0083] Please see Figure 2 , Figure 6 In some embodiments of this application, the adjusting member 30 includes a main body 31 and a connecting part 32 connected to one end of the main body 31 facing away from the deformable part 111, and the connecting part 32 is fastened to the connecting hole 211.

[0084] It should be noted that the main body 31 is located at the end of the connecting part 32 near the deformable part 111, and the outer peripheral surface of the main body 31 is provided with external threads. The main body 31 is threadedly connected to the threaded hole 1111 of the deformable part 111. The connecting part 32 is connected to the end of the main body 31 facing away from the deformable part 111, and the connecting part 32 is axially limited and rotatably connected to the connecting hole 211. The main body 31 and the connecting part 32 can be integrally formed and integrally connected, or they can be connected separately. The separate connection method can be welding, bonding, etc.

[0085] It should also be noted that the connecting part 32 is fastened to the connecting hole 211. Based on this fastening, the adjusting member 30 can be restricted to axial movement in at least one direction. For example, as... Figure 2 As shown, when the connecting part 32 is engaged with the connecting hole 211, the adjusting member 30 can be restricted to move axially in the direction close to the resonant cavity 13. For example, as... Figure 6 As shown, when the connecting part 32 is upside down on the connecting hole 211, the adjusting member 30 can be restricted to move axially in the direction away from the resonant cavity 13.

[0086] By adopting the above scheme, the adjusting member 30 can be threadedly connected to the deformable part 111 via the main body 31, and can be axially and rotatably connected to the support member 20 via the connecting part 32. In particular, the snap-fit ​​between the connecting part 32 and the connecting hole 211 can restrict the axial movement of the adjusting member 30 in at least one direction. Based on this, the adjusting member 30 can be directly and quickly fitted with the connecting hole 211, and the axially and rotatably connected can be quickly and reliably achieved without the need for other components such as snap rings or limiting caps. As a result, the structure of the adjusting member 30 can be simplified and optimized, the connection operation between the adjusting member 30 and the deformable part 111 and between the adjusting member 30 and the support member 20 can be simplified, and the installation method and connection operation of the adjusting member 30 can be simplified and made more convenient.

[0087] Of course, in other embodiments, without using other components such as retaining rings or limiting caps, the axially limited rotatable connection between the connecting part 32 and the connecting hole 211 can be achieved in other ways. For example, the connecting part 32 can be flanged and riveted to the connecting hole 211 to achieve an axially limited rotatable connection. Alternatively, an elastic structure can be provided on the connecting part 32. After the connecting part 32 is inserted into the connecting hole 211, the elastic structure can deform to produce an axial limiting effect, while still allowing the connecting part 32 to rotate.

[0088] Please see Figure 2 , Figure 6 In some embodiments of this application, the connecting portion 32 includes a connecting section 321, a stop protrusion 322, and a snap-fit ​​protrusion 323. The connecting section 321 passes through the connecting hole 211. The stop protrusion 322 protrudes outward from one end of the connecting section 321 and stops at one side of the connecting hole 211. The snap-fit ​​protrusion 323 protrudes outward from the other end of the connecting section 321 and snaps onto the other side of the connecting hole 211.

[0089] It should be noted that the connecting segment 321 passes through the connecting hole 211 and has rotational freedom within the connecting hole 211. The shape of the connecting segment 321 can be, but is not limited to, cylindrical, arc-shaped, annular, etc. The outer circumferential surface of the connecting segment 321 and the wall of the connecting hole 211 can be a clearance fit, a transition fit, or a small interference fit.

[0090] The stop protrusion 322 and the latching protrusion 323 are respectively disposed at opposite ends of the connecting section 321, and are formed to protrude outward from the outer periphery of the connecting section 321. The stop protrusion 322 may extend continuously or discontinuously along the circumferential direction of the connecting portion 32. The latching protrusion 323 may extend continuously or discontinuously along the circumferential direction of the connecting portion 32. The stop protrusion 322 and the connecting section 321 may be integrally formed or separately connected. The latching protrusion 323 and the connecting section 321 may be integrally formed or separately connected.

[0091] The stop protrusion 322 can limit and stop on one side of the connecting hole 211, and the snap protrusion 323 can snap onto the other side of the connecting hole 211. Based on this, the stop protrusion 322 and the snap protrusion 323 can achieve double-sided limiting of the connecting part 32 and the connecting hole 211 in the axial direction.

[0092] like Figure 2 As shown, in some embodiments, a stop protrusion 322 is provided at one end of the connecting section 321 near the main body 31, and a latching protrusion 323 is provided at the end of the connecting section 321 away from the main body 31, so that the connecting part 32 is hooked onto the connecting hole 211. In this case, the connecting part 32 can be rotatably connected to the connecting hole 211 via the connecting section 321, and can be stopped by the stop protrusion 322 at the edge of the connecting hole 211 near the deformable part 111 to restrict the axial movement of the adjusting member 30 in the direction away from the resonant cavity 13, and can be hooked onto the edge of the connecting hole 211 away from the deformable part 111 via the latching protrusion 323 to restrict the axial movement of the adjusting member 30 in the direction near the resonant cavity 13, thereby allowing the adjusting member 30 to be axially limited on both sides relative to the connecting hole 211, and allowing the adjusting member 30 to remain axially stationary. Optionally, the stop protrusion 322 can extend continuously along the circumference of the connecting portion 32, and the outer peripheral surface of the stop protrusion 322 coincides with the outer peripheral surface of the main body portion 31. With this configuration, the stop protrusion 322 and the main body portion 31 can form an integral cylindrical shape, facilitating the processing and shaping of both. This is equivalent to the stop protrusion 322 being considered part of the main body portion 31, allowing its outer peripheral surface to also participate in the setting of external threads. It is also equivalent to using a part of the main body portion 31 as the stop protrusion 322, utilizing the end face of the main body portion 31 to achieve a stopping and limiting effect. Of course, the shape and size of the stop protrusion 322 can also differ from the shape and size of the main body portion 31.

[0093] like Figure 6 As shown, in some other embodiments, a snap-fit ​​protrusion 323 is provided at one end of the connecting section 321 near the main body 31, and a stop protrusion 322 is provided at the end of the connecting section 321 away from the main body 31, so that the connecting part 32 is snapped against the connecting hole 211. In this case, the connecting part 32 can be rotatably connected to the connecting hole 211 via the connecting section 321, and can be stopped by the stop protrusion 322 at the edge of the connecting hole 211 away from the deformable part 111 to limit the axial movement of the adjusting member 30 in the direction close to the resonant cavity 13, and can be snapped against the edge of the connecting hole 211 near the deformable part 111 via the snap-fit ​​protrusion 323 to limit the axial movement of the adjusting member 30 in the direction away from the resonant cavity 13, thereby allowing the adjusting member 30 to be axially limited on both sides relative to the connecting hole 211, and allowing the adjusting member 30 to remain axially stationary.

[0094] By adopting the above solution, the connecting part 32 can be rotatably connected to the connecting hole 211 via the connecting section 321; the connecting part 32 can also be limited and stopped on one side of the connecting hole 211 via the stop protrusion 322, and fastened to the other side of the connecting hole 211 via the snap-fit ​​protrusion 323, thus achieving axial limitation on both sides of the connecting hole 211. Based on this, the structure of the connecting part 32 can be simplified and optimized, enabling the connecting part 32 to be conveniently, quickly, and reliably rotatably connected to the connecting hole 211 with axial limitation, thereby improving the ease of connection operation, connection reliability, and connection stability between the connecting part 32 and the connecting hole 211.

[0095] Furthermore, since the adjusting member 30 is axially limited on both sides relative to the connecting hole 211, the rotational stability of the adjusting member 30 in the connecting hole 211 can be improved. The adjusting member 30 can both drive the deformable part 111 to deform towards the side closer to the resonant cavity 13 and drive the deformable part 111 to deform away from the resonant cavity 13, thereby realizing bidirectional adjustment of the resonant frequency. This can improve the ease of tuning operation, controllability, and stability, expand the tuning range, and optimize the tuning index.

[0096] Furthermore, since the adjusting member 30 can remain axially stationary, the size of the adjusting member 30 protruding from the support member 20 can be small, or even the adjusting member 30 can be completely concealed from the support member 20. This can help reduce the overall size of the resonator and facilitate its miniaturization. It can also reduce the risk of the adjusting member 30 being accidentally touched, collided with, or damaged, improve the stability and effectiveness of the tuning performance, and enhance the reliability of the adjusting member 30 and the resonator.

[0097] Furthermore, based on the configuration of this embodiment, the connecting section 321, the stop protrusion 322, and the snap-fit ​​protrusion 323 of the connecting part 32 can be pre-processed and formed before the connecting part 32 is installed into the connecting hole 211. During assembly, the connecting part 32 can be axially limited and rotatably connected to the connecting hole 211 through elastic deformation. Specifically, during the assembly process of installing the connecting part 32 into the connecting hole 211, the snap-fit ​​protrusion 323 will adaptively deform inward under the action of the hole wall of the connecting hole 211 until the snap-fit ​​protrusion 323 protrudes out of the connecting hole 211. The snap-fit ​​protrusion 323 then recovers its elastic deformation under its own elastic action and snaps onto the edge of the connecting hole 211. Therefore, based on this embodiment, the assembly process is relatively simplified, and the assembly convenience and efficiency are high.

[0098] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, a cut-off groove 324 is provided on the end side of the connecting segment 321 near the buckle protrusion 323.

[0099] It should be noted that a cutting groove 324 is provided on the end side of the connecting segment 321 near the snap-fit ​​protrusion 323 (i.e., the end side of the connecting segment 321 away from the stop protrusion 322), and at least one cutting groove 324 is provided. The cutting groove 324 extends radially along the connecting portion 32, and the groove depth of the cutting groove 324 is greater than or equal to the dimension of the snap-fit ​​protrusion 323 along the axial direction of the connecting portion 32, such that the cutting groove 324 at least cuts off a portion of the connecting segment 321 and the snap-fit ​​protrusion 323.

[0100] By adopting the above solution, the circumferential continuity between the snap-fit ​​protrusion 323 and the connecting segment 321 can be interrupted by the cut-off groove 324, and the cut-off groove 324 provides partial deformation space for both the snap-fit ​​protrusion 323 and the connecting segment 321. Based on this, during the assembly process of the connecting part 32 being installed in the connecting hole 211, the snap-fit ​​protrusion 323 and the connecting segment 321 can be easily deformed inwards under the action of the hole wall of the connecting hole 211, reducing the resistance to the inward shrinkage deformation of the snap-fit ​​protrusion 323 and the connecting segment 321, thereby improving the assembly convenience and efficiency of the connecting part 32 and the connecting hole 211. Therefore, this embodiment is mainly applicable to the assembly method where the connecting part 32 is installed in the connecting hole 211 by deformation.

[0101] Of course, in other embodiments, the connecting portion 32 may not be provided with the cutting groove 324, but the connecting segment 321 and the snap-fit ​​protrusion 323 may be divided into a plurality of snap-fit ​​structures arranged at intervals along the circumference of the connecting portion 32.

[0102] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the adjusting member 30 has an operating part 33 at one end facing away from the deformable part 111. The operating part 33 may be, but is not limited to, a groove, an opening, a boss, an outer peripheral protrusion, or other structures.

[0103] By adopting the above solution, it is convenient and quick for a person or an external tool to drive the adjustment member 30 to rotate via the operating part 33, thereby improving the ease of operation of the adjustment member 30 and improving the simplicity, controllability and stability of the tuning operation.

[0104] Of course, in other embodiments, the adjusting member 30 may not have an operating part 33. The operator can apply force to the adjusting member 30 by means of a suction cup, the friction of a human hand, a tool with a large friction (e.g., a tool with a rough rubber part at the end of the tool), or a sticky tool (e.g., a tool with adhesive at the end of the tool), to drive the adjusting member 30 to rotate.

[0105] Please see Figure 1 , Figure 2 , Figure 3In some embodiments of this application, the snap-fit ​​protrusion 323 is located at the end of the connecting section 321 away from the main body 31, and a cut-off groove 324 is formed on the end side of the connecting section 321 near the snap-fit ​​protrusion 323. The cut-off groove 324 serves as the operating part 33. That is, in this embodiment, the cut-off groove 324 is located at the end of the adjusting member 30 facing away from the deformable part 111, and the cut-off groove 324 serves as the operating part 33.

[0106] By adopting the above solution, when the end of the adjusting member 30 facing away from the deformable part 111 already has a cut-off groove 324, the cut-off groove 324 can be directly used as the operating part 33, making it convenient and quick for a person or external tool to drive the adjusting member 30 to rotate via the cut-off groove 324. Based on this, not only can the ease of operation of rotating the adjusting member 30 be improved, but the cut-off groove 324 and the operating part 33 can also be combined into one, thereby improving the design and processing convenience of the operating part 33, simplifying and optimizing the structure of the adjusting member 30, and improving the processing convenience and structural reliability of the adjusting member 30.

[0107] Of course, in other embodiments, the cut-off groove 324 and the operation part 33 can be set independently.

[0108] Please see Figure 7 In some embodiments of this application, the end of the adjusting member 30 facing away from the deformable part 111 is bent to form a flange 34, and the flange 34 stops at the edge of the connecting hole 211.

[0109] Based on the configuration of this embodiment, before the adjusting member 30 is installed into the connecting hole 211, the end of the adjusting member 30 facing away from the deformable part 111 can be set straight (i.e., the flange 34 is not formed initially) to facilitate, quickly, and smoothly insert the adjusting member 30 into the connecting hole 211. After the adjusting member 30 is inserted into the connecting hole 211, the end of the adjusting member 30 facing away from the deformable part 111 can be squeezed, punched, or riveted to facilitate and quickly bend the end of the adjusting member 30 facing away from the deformable part 111 to form the flange 34. This flange 34 then stops the adjusting member 30 at the edge of the connecting hole 211 away from the deformable part 111, thereby restricting the axial movement of the adjusting member 30 along the direction close to the resonant cavity 13. Thus, the adjusting member 30 can be conveniently, quickly, and reliably rotatably connected to the connecting hole 211 with axial limitation, improving the ease of operation, reliability, and stability of the connection between the adjusting member 30 and the connecting hole 211.

[0110] like Figure 7As shown, in some embodiments, in addition to limiting the axial movement of the adjusting member 30 along the direction close to the resonant cavity 13 via the flange 34, the adjusting member 30 may be provided with a shoulder 35 to stop at the edge of the connecting hole 211 near the deformed portion 111. This achieves the limitation of the adjusting member 30 along the direction away from the resonant cavity 13 via the shoulder 35, so that the adjusting member 30 can be axially limited on both sides of the connecting hole 211 via the flange 34 and the shoulder 35, so that the adjusting member 30 can not move axially. Of course, in other embodiments, the adjusting member 30 may not be provided with a shoulder 35, and the axial movement of the adjusting member 30 along the direction close to the resonant cavity 13 may only be limited by the flange 34.

[0111] Please see Figure 2 , Figure 3 In some embodiments of this application, the deformable part 111 is made of soft aluminum alloy material.

[0112] By adopting the above scheme, the material of the deformable part 111 is a high-toughness soft aluminum alloy, which can improve the toughness of the deformable part 111, facilitate the deformation of the deformable part 111 according to the stress, and improve the reliability and service life of the deformable part 111.

[0113] Of course, in other embodiments, the deformable part 111 may be made of other plastic metal materials that are deformable and do not spring back automatically after deformation.

[0114] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the support member 20 is made of hard aluminum alloy.

[0115] By adopting the above scheme, the material of the support member 20 is hard aluminum alloy, and the material of the fixing part 112 is high-toughness soft aluminum alloy. Both the support member 20 and the fixing part 112 are made of aluminum alloy, which facilitates a reliable and stable connection and fixation between the support member 20 and the fixing part 112.

[0116] This embodiment is particularly suitable for application in conjunction with the embodiment of "welding the support member 20 to the fixing part 112". Both the support member 20 and the fixing part 112 are made of aluminum alloy, which facilitates laser welding between the support member 20 and the fixing part 112, and can improve the welding effect and welding strength, thereby improving the connection efficiency, connection reliability and connection stability between the support member 20 and the fixing part 112.

[0117] Of course, in other embodiments, the material of the support member 20 can be other metal materials or non-metal materials. Non-metal materials can be wood, plastic, ceramic, etc., as long as they can properly support the adjustment member 30 so as to facilitate the tuning operation.

[0118] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the adjusting member 30 is made of steel. For example, the adjusting member 30 may be made of stainless steel, spring steel, etc.

[0119] By adopting the above solution, the structural strength and rigidity of the adjusting component 30 can be improved, the degree of wear and damage of the adjusting component 30 during rotation can be reduced, the reliability of the adjusting component 30 can be improved, and the service life of the adjusting component 30 can be extended.

[0120] Of course, in other embodiments, the adjusting member 30 may be made of other metallic materials. Alternatively, if the threaded hole 1111 is a blind hole, the adjusting member 30 may be made of non-metallic materials.

[0121] Please see Figure 1 , Figure 2 , Figure 3 In some embodiments of this application, the cover plate 11 is a single-layer cover plate that is integral. In this embodiment, the single-layer cover plate can be processed by slotting to form a relatively thin deformable portion 111.

[0122] By adopting the above solution, by making the cover plate 11 an integral single-layer cover plate, it is easier to integrally form the cover plate 11, which can improve the processing convenience and consistency of the cover plate 11, improve the assembly convenience of the cover plate 11 with other parts of the resonator housing 10 and other components, reduce the number of parts of the cover plate 11 and the resonator, and improve the assembly convenience and assembly efficiency of the resonator.

[0123] Of course, in other embodiments, the cover plate 11 may be a split single-layer cover plate, that is, the deformable part 111 may be separately connected to the inner peripheral surface of the fixed part 112.

[0124] Please see Figure 8 In some embodiments of this application, the cover plate 11 is a double-layer cover plate, which includes a first plate 113 and a second plate 114. The second plate 114 has a fixing part 112. The first plate 113 is stacked on the side of the second plate 114 away from the support member 20 and has a deformable part 111.

[0125] It should be noted that the first plate 113 is stacked on the side of the second plate 114 away from the support member 20 (i.e., the side closer to the resonant cavity 13). The portion of the first plate 113 that overlaps with the second plate 114 is connected and fixed to the fixing portion 112 of the second plate 114. The connection and fixing method between the first plate 113 and the second plate 114 can be, but is not limited to, welding, bonding, riveting, fastener connection, etc. The portion of the first plate 113 other than the portion connected to the second plate 114 can form a deformable portion 111.

[0126] By adopting the above scheme, the cover plate 11, through the stacked and separately connected first plate 113 and second plate 114, can jointly cover the other parts of the resonator housing 10, thus achieving a shielding function and preventing signal leakage. Furthermore, the cover plate 11 can form a deformable portion 111 through the first plate 113 and a fixed portion 112 through the second plate 114. Since the first plate 113 can be independently formed, the deformable portion 111 can be thinned to a greater extent. This allows all parts of the first plate 113, except for the portion connected to the second plate 114, to form deformable portions 111. This results in lower deformation resistance and a larger deformation range for the deformable portion 111, thereby improving the ease of adjustment and adjustable range of the deformable portion 111. Furthermore, since the second plate 114 and the first plate 113 are separately formed and separately connected, the second plate 114 and the first plate 113 can be made of the same or different materials, which helps to reduce the weight of the cover plate 11 and the resonator, which helps to lighten the resonator and reduce the cost of the cover plate 11 and the resonator.

[0127] Please see Figure 1 Some embodiments of this application provide a filter including one or more resonators provided in the embodiments of this application. When multiple resonators are provided, they can be arranged in a specific layout, and coupling relationships can be established between adjacent resonators as needed.

[0128] By adopting the above scheme, the filter can improve the ease of tuning operation, controllability, and stability, and improve the tuning effect and filter performance by using the resonator provided in the embodiments of this application.
