Description

Technical Field

[0001] This application relates to the field of communication equipment accessories technology, and in particular to a circulator / isolator cavity assembly, a circulator / isolator, and base station equipment. Background Technology

[0002] Existing microwave isolators / circulators are typically cylindrical, consisting of a uniform magnetic sheet, a permanent magnet, microwave ferrite, and a central conductor housed within a cavity of a casing, which is then locked in place with a cover. In general, the outer diameter of the casing assembly of microwave isolators / circulators in 4G communication equipment is typically greater than 10 mm, while in 5G communication equipment, the outer diameter is typically around 7 to 10 mm, or even smaller. Now, with the advent of 6G technology, microwave isolators / circulators are generally mounted and fixed onto a substrate inside communication equipment, leading to increasingly stringent requirements for miniaturization in terms of peripheral dimensions and height.

[0003] In existing technologies, the assembly and fixing methods for the shell and cover can be roughly divided into the following categories:

[0004] (1) The cover is fixed by forming an external thread on its outer edge, which engages with an internal thread formed on the inner wall of the housing, as disclosed in patent CN110854493A. However, this method can easily cause the side wall of the housing to stretch outward under stress, resulting in an insecure threaded lock between the cover and the housing. Furthermore, the threaded lock is prone to generating scraping metal debris when rotating. If the metal debris falls into the cavity, it may come into contact with internal components, causing a short circuit or other adverse conditions.

[0005] (2) As disclosed in patent CN113113747A, after the cover and shell are assembled in the vertical direction, the upper end face of the reinforcing part is pressed down by a riveting jig, causing the reinforcing part to deform under force (in terms of shape, it becomes shorter and thicker), thereby causing the reinforcing part located in the through hole to be fixed by interference with the inner wall of the through hole. However, this riveting fixing method will cause irreversible deformation of the reinforcing part, which is not conducive to disassembly.

[0006] Therefore, a completely new circulator / isolator cavity assembly needs to be designed to solve the above-mentioned technical problems. Summary of the Invention

[0007] The main objective of this application is to provide a circulator / isolator cavity assembly, a circulator / isolator, and a base station device. The circulator / isolator cavity assembly has a simple structure, is easy to package, and is easy to disassemble.

[0008] To achieve the above objectives, this application adopts the following technical solution:

[0009] A circulator / isolator cavity assembly includes: a metal housing and a metal cover plate. The metal housing includes a base plate and a peripheral wall extending upward from the periphery of the base plate. The metal cover plate covers the metal housing to form a receiving cavity surrounded by the base plate, the peripheral wall, and the metal cover plate. A connecting block extends upward from the peripheral wall and is embedded in the edge of the metal cover plate.

[0010] The metal cover plate is provided with a guide groove and a slider fixed to the guide groove. The slider can withstand the driving force in the sliding direction, thereby allowing the slider to slide between a locked position and a disassembled position.

[0011] When the slider is in the locked position, it bears pressure from the connecting block. The pressure is at a certain angle to the sliding direction, which causes the connecting block and the metal cover to self-lock, preventing the metal cover from disengaging from the metal housing. Additionally, the slider and the guide groove self-lock, preventing the slider from sliding with the metal cover.

[0012] When the slider moves to the disassembly position under the driving force, the slider disengages from the connecting block, allowing the metal cover to disengage from the metal housing.

[0013] To achieve the above objectives, this application also adopts the following technical solution:

[0014] A circulator / isolator cavity assembly includes: a metal housing and a metal cover plate. The metal housing includes a base plate and a peripheral wall extending upward from the periphery of the base plate. The metal cover plate covers the metal housing to form a receiving cavity surrounded by the base plate, the peripheral wall, and the metal cover plate. A connecting block extends upward from the upper edge of the peripheral wall and is embedded in the edge of the metal cover plate.

[0015] The metal cover plate is provided with a guide groove and a slider. The guide groove is formed by an upward opening on the upper surface of the metal cover plate, and the slider is inserted into the opening and slidably fixed in the guide groove.

[0016] The slider can withstand the driving force in the sliding direction, thereby allowing the slider to slide between a locked position and a disassembled position;

[0017] When the slider is in the locked position, the slider bears pressure from the connecting block, causing the connecting block and the metal cover to self-lock, preventing the metal cover from disengaging from the metal housing, and the slider and the guide groove to self-lock, preventing the slider from disengaging from the metal cover.

[0018] When the slider moves to the disassembly position under the action of the driving force, the slider disengages from the connecting block, allowing the metal cover to disengage from the metal housing.

[0019] Furthermore, the slider has a dovetail shape in the horizontal cross section, and the guide groove of the metal cover plate that cooperates with the slider also has a dovetail shape in the horizontal cross section.

[0020] Furthermore, the guide groove is disposed on the edge of the metal cover plate, and the wider side of the dovetail shape of the guide groove faces the connecting block, while the narrower side of the dovetail shape faces away from the connecting block.

[0021] Furthermore, the narrower side of the dovetail-shaped guide groove extends through the edge of the metal cover plate in a direction parallel to the plane of the metal cover plate, and the guide groove is located outside the implantation groove.

[0022] Furthermore, the metal cover plate is provided with an implantation groove for receiving the connecting block. The implantation groove is connected to the guide groove, so that when the metal cover plate is closed on the metal housing, the connecting block is inserted into the implantation groove and can press against the slider. The width of the connection between the implantation groove and the guide groove is smaller than the width of the wider side of the dovetail shape of the guide groove.

[0023] Furthermore, the guiding direction of the guide groove is perpendicular to the metal cover plate.

[0024] Furthermore, the mating surface between the connecting block and the slider is inclined.

[0025] Furthermore, the metal cover plate is provided with an implantation groove for receiving the connecting block, and the guide groove and the implantation groove are arranged adjacent to each other in a direction parallel to the plane of the metal cover plate.

[0026] Furthermore, the adjacent arrangement direction of the guide groove and the implantation groove is parallel to the extending direction of the edge of the metal cover plate; or, the adjacent arrangement direction of the guide groove and the implantation groove is perpendicular to the extending direction of the edge of the metal cover plate.

[0027] Furthermore, the sliding direction of the slider forms a certain angle with the direction perpendicular to the metal cover plate, and the mating surface between the connecting block and the slider is perpendicular to the plane of the metal cover plate; or, the sliding direction of the slider is perpendicular to the plane of the metal cover plate, and the mating surface between the connecting block and the slider forms a certain angle with the direction perpendicular to the plane of the metal cover plate.

[0028] Furthermore, the included angle is greater than 0 degrees and not greater than 20 degrees.

[0029] To achieve the above objectives, this application also adopts the following technical solution:

[0030] A ring-shaped device / isolator includes a ring-shaped device / isolator cavity assembly as described in any of the above claims, and components disposed within the receiving cavity, wherein the components include at least a sheet-shaped uniform magnetic sheet, ferrite, and a central conductor.

[0031] To achieve the above objectives, this application also adopts the following technical solution:

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0049] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "combination," "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0050] In the description of this application, it should be understood that the terms “comprising” and “having” as used herein, and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are expressly listed, but may include other steps or units that are not expressly listed or that are inherent to such process, method, product, or apparatus.

[0051] Please refer to Figures 1 to 7The diagram shows a first embodiment of a circulator / isolator cavity assembly disclosed in this application. The circulator / isolator cavity assembly includes a metal housing 1 and a metal cover plate 2. The metal housing 1 includes a base plate 11 and a peripheral wall 12 extending upward from the periphery of the base plate 11. The metal cover plate 2 covers the metal housing 1 to form a receiving cavity 10 enclosed by the base plate 11, the peripheral wall 12, and the metal cover plate 2. A connecting block 121 extends upward from the peripheral wall 12 and is embedded in the edge of the metal cover plate 2. The receiving cavity 10 is used to assemble components (not shown), including at least a permanent magnet, a uniform magnetic sheet, a microwave ferrite, a central conductor, and a temperature compensation component, etc., thereby forming a complete circulator / isolator. The circulator / isolator can be installed in a communication base station.

[0052] Furthermore, at least two pin notches 122 are provided on the peripheral wall 12 of the metal housing 1. The pin notches 122 are for the pins of the central conductor assembled in the receiving cavity 10 to be led out and electrically connected to the circuit board inside the base station.

[0053] Please refer to Figures 1 to 7 As shown, a through hole (not labeled) is formed at the edge of the metal cover plate 2 along a direction perpendicular to the plane of the metal cover plate 2 (in this embodiment, it is illustrated as the axial direction of the circulator / isolator). The through hole includes a guide groove 20 and an implantation groove 201. The guide groove 20 and the implantation groove 201 are adjacent to and connected in a direction parallel to the plane of the metal cover plate 2. The guide groove 20 forms an upward opening (not labeled) from the upper surface of the metal cover plate 2, and the implantation groove 201 forms an downward insertion port (not labeled) from the lower surface of the metal cover plate 2. In a preferred embodiment, both the guide groove 20 and the implantation groove 201 penetrate the metal cover plate 2 along a direction perpendicular to the plane of the metal cover plate 2.

[0054] The connecting block 121 of the metal housing 1 is inserted into the implantation groove 201 from bottom to top through the insertion port. The circulator / isolator cavity assembly also includes several sliders 3, which are inserted downward through the opening and slidably fixed in the guide groove 20, and can press against the connecting block 121. The sliders 3 can withstand the driving force in the sliding direction, thereby allowing the sliders 3 to slide between a locked position and a disassembled position. When the sliders 3 are in the locked position ( Figure 1In the indicated position, the slider 3 bears pressure from the connecting block 121. This pressure forms a certain angle with the sliding direction, causing the connecting block 121 to self-lock with the metal cover plate 2, thereby preventing the metal cover plate 2 from disengaging from the metal housing 1. Furthermore, the slider 3 self-locks with the guide groove 20, preventing sliding between the slider 3 and the metal cover plate 2. When the slider 3 moves upward to the disassembly position under the driving force, the slider 3 disengages from the connecting block 121, allowing the metal cover plate 2 to disengage from the metal housing 1.

[0055] Please refer to Figures 1 to 7 In the illustrated embodiment, the slider 3 has a dovetail shape in its horizontal cross-section, and the guide groove 20 that mates with the slider 3 on the metal cover plate 2 also has a dovetail shape in its horizontal cross-section. The wider side of the dovetail shape of the guide groove 20 faces the connecting block 121, while the narrower side faces away from the connecting block 121. The width at the connection between the implantation groove 201 and the guide groove 20 is smaller than the width of the wider side of the dovetail shape of the guide groove 20. Furthermore, the narrower side of the dovetail shape of the guide groove 20 extends through the edge of the metal cover plate 2 in a direction parallel to the plane of the metal cover plate 2, forming an opening.

[0056] Please refer to Figures 1 to 7 In the illustrated embodiment, the guiding direction of the guide groove 20 is perpendicular to the metal cover plate 2. That is, after the slider 3 is inserted into the guide groove 20 from top to bottom through the opening, it moves in a direction perpendicular to the plane of the metal cover plate 2 under downward driving force / pressure until it reaches the locked position. In the locked position, the mating surfaces between the connecting block 121 and the slider 3 are inclined, and the inclination angle is within the self-locking angle range (in the illustrated embodiment, this is manifested as: the connecting block 121 is inclined towards the first surface 1211 of the slider 3, and the slider 3 is also inclined towards the second surface 301 of the connecting block 121), thus providing a self-locking condition between the connecting block 121 and the slider 3. Simultaneously, the slider 3 and the inner wall of the guide groove 20, and the connecting block 121 and the inner wall of the insertion groove 201 are both within the self-locking angle range, thereby locking the slider 3, the metal cover plate 2, and the connecting block 121 together, preventing the metal cover plate 2 from detaching from the metal shell 1.

[0057] Please refer to Figures 1 to 7In the illustrated embodiment, the adjacent arrangement direction of the guide groove 20 and the implantation groove 201 is perpendicular to the extending direction of the edge of the metal cover plate 2 (here referring to the tangent direction at the corresponding edge position of the metal cover plate 2). Of course, in other embodiments, the adjacent arrangement direction of the guide groove 20 and the implantation groove 201 can be designed to be parallel to the extending direction of the edge of the metal cover plate 2 (again referring to the tangent direction at the corresponding edge position of the metal cover plate 2). Alternatively, in other embodiments, the adjacent arrangement direction of the guide groove 20 and the implantation groove 201 can be any direction parallel to the extending plane of the metal cover plate 2.

[0058] Furthermore, Figures 1 to 7 In the embodiment shown, the sliding direction of the slider 3 is perpendicular to the plane of the metal cover plate 2, and the mating surface between the connecting block 121 and the slider 3 forms a certain angle with the direction perpendicular to the plane of the metal cover plate 2. The angle is preferably greater than 0 degrees and not greater than 20 degrees to ensure that the slider 3, the metal cover plate 2 and the connecting block 121 can be self-locking and stable.

[0059] Please refer to Figures 8 to 14 The image shows a second embodiment of the annular / isolator cavity assembly of this application. In the second embodiment, the shape and position of the slider 3, the shape of the through hole, and the shape of the connecting block 121 are different from those in the first embodiment.

[0060] In the first embodiment, the surfaces of the connecting block 121 and the slider 3 that contact each other are inclined, so that the mating surfaces between the connecting block 121 and the slider 3 are inclined. In the second embodiment, the surfaces of the connecting block 121 and the slider 3 that contact each other are upright, so that the mating surfaces between the connecting block 121 and the slider 3 are upright (or the mating surfaces between the connecting block 121 and the slider 3 are perpendicular to the plane of the metal cover plate 2).

[0061] In the first embodiment, the guide groove 20 penetrates the metal cover plate 2 in a direction perpendicular to the plane of the metal cover plate 2, so that the sliding direction of the slider 3 is perpendicular to the plane of the metal cover plate 2. In the second embodiment, the guide groove 20 penetrates the metal cover plate 2 in a direction inclined to the direction perpendicular to the plane of the metal cover plate 2, so that the sliding direction of the slider 3 forms a certain angle with the direction perpendicular to the metal cover plate 2.

[0062] In the first embodiment, the guide groove 20 is located outside the implantation groove 201, and the outer side of the guide groove 20 (the narrower side of the dovetail shape of the guide groove 20) penetrates the edge of the metal cover plate. In the second embodiment, the guide groove 20 is located inside the implantation groove 201, and the through hole formed by the guide groove 20 and the implantation groove 201 does not penetrate the edge of the metal cover plate along the direction of the plane where the metal cover plate 2 is located.

[0063] In the first embodiment, the sliding direction of the slider 3 is perpendicular to the plane of the metal cover plate 2, and the mating surface between the connecting block 121 and the slider 3 forms a certain angle with the direction perpendicular to the plane of the metal cover plate 2. This angle is preferably greater than 0 degrees and not greater than 20 degrees (more preferably greater than 0 degrees and less than 5 degrees). In the second embodiment, the sliding direction of the slider 3 forms a certain angle with the direction perpendicular to the metal cover plate 2. This angle is preferably greater than 0 degrees and not greater than 20 degrees (more preferably greater than 0 degrees and less than 5 degrees), and the mating surface between the connecting block 121 and the slider 3 is perpendicular to the plane of the metal cover plate 2.

[0064] Furthermore, in the first embodiment of this application, the slider 3 is designed as a dovetail shape in the horizontal cross-section, solely to ensure that the slider 3 will not detach from the edge opening of the metal cover plate 2 along the plane of the metal cover plate 2. The specific shape of the slider 3 can be appropriately varied. For example, in the second embodiment, the slider 3 is roughly convex in the horizontal cross-section, but it can also be designed as a rectangle, trapezoid, etc.

[0065] Furthermore, in the first and second embodiments of this application, the guide groove 20 and the implantation groove 201 are preferably directly connected, so that the slider 3 and the connecting block 121 directly press against each other. In other embodiments, a thin partition wall (not shown) can be provided between the slider 3 and the connecting block 121, and the partition wall can achieve indirect pressing between the slider 3 and the connecting block 121 to produce a self-locking effect.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
