Abstract

The present application discloses a microwave circulator housing assembly and a microwave circulator, which are used to be mounted on the main board of a communication device. The microwave circulator housing assembly includes a housing for accommodating components and a cover plate for encapsulating the components in the housing. The housing includes a bottom wall and a side wall surrounding the bottom wall and extending upward from the bottom wall. The side wall and the bottom wall together define a cavity. An upper edge of the side wall forms a crossbeam structure. After being extruded, the crossbeam structure protrudes toward the side of the cavity and can cooperate with the cover plate to limit the cover plate from detaching upward from the housing. A relief cavity is formed at a position below the crossbeam structure of the side wall, and the stability is better.

Description

Technical Field

[0001] The present application relates to the technical field of communication equipment accessories, and in particular to a microwave circulator housing assembly and a microwave circulator. Background Art

[0002] The outer diameter of the housing assembly of microwave circulators in existing 4G communication equipment is relatively large, typically exceeding 10 mm. However, for 5G communication equipment, the outer diameter of the housing assembly needs to be further reduced to approximately 7 mm, or even smaller. Chinese Utility Model Patent ZL201420677194.4, published on March 25, 2015, discloses a microwave circulator for fourth-generation mobile communication equipment. The cavity has an external thread, and the cover plate has an internal thread. These threads mate to secure components, making thread processing time-consuming and labor-intensive, resulting in high costs. Furthermore, the cover plate threads are positioned inside the cavity. When the cavity size is reduced and the sidewalls become thinner, this can easily lead to problems such as cavity expansion and thread stripping. This can lead to poor electrical performance of the microwave circulator and insecure component fixation. Furthermore, machining the cavity and cover plate threads reduces production efficiency and increases costs. Summary of the Invention

[0003] The main purpose of the present application is to provide a microwave circulator housing assembly and a microwave circulator, wherein the microwave circulator housing assembly is not easy to loosen, is easy to package, and has a long service life.

[0004] In order to achieve the above objectives, this application adopts the following technical solutions:

[0005] A microwave circulator housing assembly is used to be installed on the mainboard of a communication device, comprising a housing for accommodating components and a cover for encapsulating the components in the housing. The housing comprises a bottom wall and side walls surrounding the bottom wall and extending above the bottom wall. The side walls and the bottom wall together form a cavity. A crossbeam structure is formed on the upper edge of the side wall. After being extruded, the crossbeam structure protrudes toward the side where the cavity is located and can cooperate with the cover to limit the cover from detaching upward from the housing. A clearance cavity is formed below the crossbeam structure of the side wall.

[0006] Furthermore, the crossbeam structure is extruded by the mold core along the thickness direction of the side wall toward the side where the cavity is located to form a hanging platform structure, and the hanging platform structure restricts the cover plate from separating upward from the shell.

[0007] Furthermore, the edge of the upper surface of the cover plate is recessed to form a locking groove, and the locking groove is formed with an inner bottom surface. The hanging platform structure correspondingly protrudes into the locking groove to limit the cover plate from separating upward from the shell.

[0008] Furthermore, the hanging platform structure has a positioning portion extending downward, and the cover plate is further recessed in the local area of the positioning groove to form a positioning recess, and the positioning portion cooperates with the positioning recess to limit the outward expansion of the side wall.

[0009] Furthermore, the positioning recess is a through hole that penetrates the cover plate in the up and down directions at the position of the positioning slot, or the positioning recess is a groove structure that is recessed downward at the position of the positioning slot, and the positioning portion is formed by the mold core extruding a part of the hanging platform structure from top to bottom.

[0010] Furthermore, the cover plate further forms a positioning recess in the positioning groove, and the positioning recess is a groove structure formed by the inner bottom surface of the positioning groove being recessed downward. The hanging platform structure is pressed from top to bottom by the mold core, and the hanging platform structure is bent downward and deformed to form a positioning portion. The positioning portion is at least partially clamped in the positioning recess to limit the outward expansion of the side wall.

[0011] Furthermore, the positioning recess is located on a side of the positioning groove away from the edge of the cover plate, and the positioning recess is in a long arc shape along the circumference of the shell. The positioning portion is one section of the hanging platform structure along the circumference of the shell.

[0012] Furthermore, the side wall is provided with a plurality of notches from top to bottom, and the cover plate includes a main body portion, which is covered on the top of the cavity.

[0013] Furthermore, a plurality of limit blocks are formed on the outer peripheral edge of the main body at positions corresponding to the notch, and the limit blocks correspond to the side walls forming the notch to limit the cover plate from rotating circumferentially relative to the shell.

[0014] Furthermore, the outer peripheral edge of the cover plate at the notch is recessed toward the axis of the shell to form an arc-shaped edge.

[0015] Furthermore, along the radial direction of the shell, the outer peripheral edge of the cover plate does not exceed the outer peripheral surface of the shell.

[0016] Furthermore, both ends of the beam structure are integrally connected to the side wall, and the clearance cavity is a closed through-hole structure penetrating the side wall along the thickness direction of the side wall.

[0017] Furthermore, along the circumferential direction of the outer peripheral surface of the shell, the extension length of the clearance cavity is not less than the total extension length of the corresponding beam structure.

[0018] Furthermore, the clearance cavity is a non-closed through-hole structure that penetrates the side wall along the thickness direction of the side wall. The clearance cavity forms an opening upward, and along the circumferential direction of the outer peripheral surface of the shell, at least one side of the opening forms the beam structure, and the beam structure is a cantilever structure with one end integrally connected to the side wall.

[0019] Furthermore, along the circumferential direction of the outer peripheral surface of the shell, a beam structure is formed on both sides of the opening.

[0020] Further, a slot is formed by the side wall being recessed in the circumferential direction of the outer peripheral surface of the housing above the notch side edge. The slot communicates with the notch in the circumferential direction of the outer peripheral surface of the housing. The relief cavity is formed by the slot, or the relief cavity is formed jointly by the slot and the notch.

[0021] Further, the crossbeam structure is a cantilever structure with one end connected to the side wall.

[0022] Further, in the circumferential direction of the outer peripheral surface of the housing, a stop groove is formed by the middle position of the upper edge of the side wall being recessed downward. The body part is located inside the side wall. The cover plate further includes a protrusion formed by protruding outward along the edge of the body part. The protrusion is correspondingly fitted into the stop groove of the side wall. The outer edge position of the protrusion further extends in the circumferential direction of the outer peripheral surface of the housing to form a limiting part. The limiting part is fitted on the outer side surface of the side wall, and the side wall is limited between the limiting part and the outer edge of the main body part.

[0023] Further, the inner bottom surface of the clamping groove interferes with the hanging platform structure in the up-and-down direction. In the up-and-down direction, the height of at least a partial area of the inner bottom surface from the edge of the cover plate inward shows an increasing trend.

[0024] Further, the inner bottom surface is planar, and the angle between the inner bottom surface and the horizontal plane is greater than 0 degrees and less than 15 degrees.

[0025] Further, the body part is located inside the side wall. The cover plate further includes a protrusion formed by protruding outward along the edge of the body part. The protrusion is correspondingly fitted into the notch of the side wall. The outer edge position of the protrusion further extends in the circumferential direction of the outer peripheral surface of the housing to form a limiting part. The limiting part is fitted on the outer side surface of the side wall, and the side wall is limited between the limiting part and the outer edge of the main body part.

[0026] To achieve the above object, the present application also adopts the following technical solution:

[0047] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0048] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application may be understood according to specific situations.

[0049] In the description of the present application, it should be understood that the terms "including" and "having" used herein and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device including a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0050] Such as Figures 1 to 17As shown, there are seven embodiments of the microwave circulator housing assembly 100 of the present application. The microwave circulator housing assembly 100 disclosed in the present application encapsulates components (not shown) inside it, thereby forming a microwave circulator. Such a microwave circulator is used in communication devices (not shown) in mobile communication technology, specifically for installation on the main board (not shown) of the communication device. Components (not shown) are installed inside the microwave circulator housing assembly of the present application to form a microwave circulator.

[0051] Please refer to Figure 1 and Figure 2 As shown, it is the first embodiment of the microwave circulator housing assembly 100 of the present application. The microwave circulator housing assembly 100 is generally cylindrical in shape as a whole, including a housing 1 for accommodating components (not shown) and a cover plate 2 for encapsulating the components inside the housing 1. The housing 1 includes a bottom wall 11 and a side wall 12 that surrounds the bottom wall 11 and extends upward from the bottom wall 11. The side wall 12 and the bottom wall 11 together enclose a cylindrical cavity 10. The side wall 12 is provided with a plurality of gaps 122 from top to bottom. The components have a plurality of connecting feet (not shown) for connecting to the main board of the communication device. After the components are installed in the cavity 10 from top to bottom, the connecting feet extend out from the corresponding gaps 122. The outer contour diameter of the housing 1 in this embodiment is about 7 mm, but it does not exclude being set to a size near 7 mm, such as 10 mm, 8 mm, or even 6 mm, etc.

[0052] Please refer to Figure 1 and Figure 2 As shown, when the components are installed in the cavity 10 from top to bottom, the cover plate 2 is closed above the components and cooperates with the side wall 12 for limiting. Specifically, the upper edge of the side wall 12 is provided with a hanging platform structure 121 that protrudes toward the side of the cavity 10 and cooperates with the cover plate 2 to limit the cover plate 2 from disengaging upward from the housing 1. Further, a clamping groove 20 is recessed at the edge position of the upper surface of the cover plate 2. The hanging platform structure 121 correspondingly protrudes into the clamping groove 20 to limit the cover plate 2 from disengaging upward from the housing 1. A relief cavity 120 is formed at the position below the hanging platform structure 121 on the side wall 12. The clamping groove 20 has an inner bottom surface 201.

[0053] Please refer to Figure 1 and Figure 2 As shown, a positioning portion 1211 extends downward from the lower surface of the hanging platform structure 121. The cover plate 2 is further recessed in the clamping groove 20 to form a positioning recess 202. The positioning portion 1211 and the positioning recess 202 cooperate to limit the outward expansion of the side wall 12. Specifically, the positioning recess 202 is a through hole that penetrates the cover plate 2 in the vertical direction at the position of the clamping groove 20, or the positioning recess 202 is a groove structure that is recessed downward at the position of the clamping groove 20.

[0054] 4Please refer toFigure 17 Combined with Figure 1 and Figure 2 As shown, Figure 17 Shown is a three-dimensional diagram of the beam structure 125 of the microwave circulator shell assembly of the first embodiment of the present application before being extruded by the mold to form the hanging platform structure 121. During assembly, after the components (not shown) are installed from top to bottom in the cavity 10, the cover plate 2 is covered, and then the beam structure 125 is extruded along the thickness direction of the side wall 12 (that is, the radial direction of the microwave circulator shell assembly 100) toward the side of the cavity 10 and hung in the positioning groove 20 through the mold. At this time, the beam structure 125 forms the hanging platform structure 121, and then the mold is used to extrude a part of the hanging platform structure 121 from top to bottom to form the positioning portion 1211. The positioning portion 1211 cooperates with the positioning recess 202 to limit the outward expansion of the side wall 12. It should be noted that although different numbers are used to represent the beam structure 125 and the hanging platform structure 121 in this application, the beam structure 125 and the hanging platform structure 121 are actually the same structure, only in different forms during the assembly process. Due to space considerations, in the remaining multiple embodiments (Examples 2 to 7), the beam structure 125 before the hanging platform structure 121 is formed is not shown separately in the drawings. Figure 17 The structure of the hanging platform 121 in the present application is hung in the clamping groove 20 to limit the cover plate 2 from separating upward from the housing 1.

[0055] Because the shell 1 needs to form a coating (for example, an electroplating layer) on its outer surface before forming the hanging platform structure 121 (that is, before the beam structure 125 is extruded by the mold core) to achieve certain performance characteristics (such as electrical properties, rust resistance, corrosion resistance, etc.). The setting of the said clearance cavity 120 can make the outer surface of the part of the side wall 12 where the hanging platform structure 121 is formed and the surrounding parts always exposed to the air, so that the coating structure can be formed fully, without dead angles, and in all directions. At the same time, the setting of the clearance cavity 120 can also ensure that during the entire process of the mold core extruding the beam structure 125 of the side wall 12, the beam structure 125 will bend and deform, but will not tear and deform (because the torn hole will produce a situation where there is no coating).

[0056] Please refer to Figure 1 and Figure 2As shown, in the present application, the cover plate 2 includes a body portion 21, and the body portion 21 is disposed above the cavity 10. Both ends of the hanging platform structure 121 (meaning both ends of the hanging platform structure 121 along the circumferential direction of the housing 1) are integrally connected to the side wall 12, and the relief cavity 120 is a closed through-hole structure that penetrates the side wall 12 along the thickness direction of the side wall 12. Along the circumferential direction of the outer peripheral surface of the housing 1, the extension length of the relief cavity 120 is not less than the extension length of the corresponding hanging platform structure 121 (that is, the crossbeam structure 125) (here, the extension length refers to the extension length along the circumferential direction of the housing 1). In a preferred embodiment, the extension length of the relief cavity 120 is greater than the extension length of the corresponding hanging platform structure 121 (that is, the crossbeam structure 125). Such a design can further ensure that during the entire process of the mold core pressing the crossbeam structure 125, the crossbeam structure 125 only undergoes bending deformation as much as possible and does not undergo tearing deformation. Of course, during the entire process, a small amount of metal extrusion and extension may occur at local positions of the hanging platform structure 121, which is normal. This can ensure that all surfaces of the housing 1 can have a coating.

[0057] In the first embodiment, specifically refer to Figure 1 and Figure 2 As shown, a hanging platform structure 121 is formed on each side wall 12, and a positioning portion 1211 is formed on each hanging platform structure 121.

[0058] Please refer to Figure 3 and Figure 6 As shown, it is the second embodiment of the microwave circulator housing assembly 100 of the present application. In the cover plate 2 of the second embodiment, a positioning recess 202 is further formed in the clamping groove 20. The positioning recess 202 is a groove structure formed by the downward depression of the inner bottom surface 201 of the clamping groove 20. The hanging platform structure 121 is pressed by the mold core from top to bottom, and the positioning portion 1211 is formed by the downward bending deformation of the hanging platform structure 121. The positioning portion 1211 is at least partially clamped in the positioning recess 202 to limit the outward expansion of the side wall 12.

[0059] In the second embodiment, the positioning recess 202 is located on a side of the clamping groove 20 away from the edge of the cover plate, and the positioning recess 202 is in a long strip arc shape. The difference between the second embodiment and the first embodiment is that the positioning portion 1211 in the first embodiment is formed by further extruding and deforming the hanging platform structure 121 by a mold core. This requires the hanging platform structure 121 to have a certain width and thickness. When the width of the hanging platform structure 121 (the width in the radial direction of the housing 1) is narrow and the thickness (the thickness in the axial direction of the housing 1) is thin, it is easy to break the hanging platform structure 121 when forming the positioning portion 1211 by the method in the first embodiment. Therefore, when the width of the hanging platform structure 121 is narrow and the thickness is thin, it is necessary to form the positioning portion 1211 by the method of the second embodiment. The positioning portion 1211 in the second embodiment is formed by bending the entire hanging platform structure 121. In other words, the positioning portion 1211 in the second embodiment is actually a section of the hanging platform structure 121 in the circumferential direction of the housing 1. Thus, when forming the positioning portion 1211, only a local position of the hanging platform structure 121 needs to generate a downward bending deformation (of course, a small amount of metal extension will also occur in actual situations), reducing the risk of the hanging platform structure 121 breaking.

[0060] Please refer to Figure 7 and Figure 8 As shown in, a third embodiment of the microwave circulator housing assembly 100 of the present application is provided. Among them, the relief cavity 120 is a non-closed through-hole structure penetrating the side wall 12 in the thickness direction of the side wall 12, and the relief cavity 120 forms an opening 1201 upward. Along the circumferential direction of the outer peripheral surface of the housing 1, at least one side of the opening 1201 forms the hanging platform structure 121. The hanging platform structure 121 is a cantilever structure integrally connected to the side wall 12 at one end. The hanging platform structure 121 is correspondingly limited by the clamping groove 20 formed on the body portion 21 of the cover plate 2. A preferred implementation manner is that along the circumferential direction of the outer peripheral surface of the housing 1, one hanging platform structure 121 is formed on each of the two sides of the opening 1201, and the hanging platform structures 121 are correspondingly limited by one or two of the clamping grooves 20 formed on the body portion 21 of the cover plate 2 respectively.

[0061] In the third embodiment, positioning portions 1211 are also formed on each hanging platform structure 121, and the positioning portions 1211 are also correspondingly limited and fixed by the positioning recesses 202 formed on the cover plate 2 to limit the outward expansion of the side wall 12. The positioning portions 1211 and the positioning recesses 202 in the third embodiment are the same as those in the first embodiment and will not be described repeatedly here.

[0062] Please refer to Figures 1 to 6As shown, which is the first embodiment and the second embodiment of the present application, a plurality of limiting blocks 23 are formed on the outer peripheral edge of the main body portion 21 corresponding to the position of the notch 122. The limiting blocks 23 are correspondingly limited by the side wall 12 forming the notch 122 to limit the circumferential rotation of the cover plate relative to the housing. Further, an arc-shaped edge 24 is formed by the outer peripheral edge of the cover plate at the notch 122 being recessed toward the axis side of the housing 1. Along the radial direction of the housing 1, the outer peripheral edge of the cover plate 2 does not extend beyond the outer peripheral surface of the housing 1. This is beneficial to the overall miniaturization of the waveguide circulator housing assembly 100.

[0063] Of course, the arc-shaped edge 24 may not be provided, such as Figure 7 and Figure 8 the structure shown in the third embodiment. However, in the third embodiment, the outer peripheral edge of the cover plate 2 also does not extend beyond the outer peripheral surface of the housing 1.

[0064] Please refer to Figure 9 and Figure 10 As shown, which is the fourth embodiment of the microwave circulator housing assembly 100 of the present application. In the fourth embodiment, two hanging platform structures 121 are formed on one side wall 12, and are correspondingly limited by two clamping slots 20 formed on the main body portion 21 of the cover plate 2. The hanging platform structure 121 and the clamping slot 20 in the fourth embodiment are similar to the structure of the first embodiment, except that the lengths of the hanging platform structure 121 and the clamping slot 20 in the fourth embodiment along the circumferential direction of the housing are shorter than those in the first embodiment. In addition, another difference is that the positioning portion 1211 and the positioning concave portion 202 structures are not provided in the fourth embodiment.

[0065] Please refer to Figure 11 and Figure 12 As shown, which is the fifth embodiment of the microwave circulator housing assembly 100 of the present application. In the fourth embodiment, one hanging platform structure 121 is formed on one side wall 12, and is correspondingly limited by one clamping slot 20 formed on the main body portion 21 of the cover plate 2. The hanging platform structure 121 and the clamping slot 20 in the fifth embodiment are the same as the structure of the first embodiment. The difference is that the positioning portion 1211 and the positioning concave portion 202 structures are not provided in the fifth embodiment.

[0066] Please refer to Figure 13 and Figure 14 As shown, which is the sixth embodiment of the microwave circulator housing assembly 100 of the present application. The hanging platform structure 121 and the clamping slot 20 in the sixth embodiment are basically the same as the structure of the third embodiment. The difference is that the positioning portion 1211 and the positioning concave portion 202 structures are not provided in the sixth embodiment.

[0067] Please refer to Figure 15 and Figure 16As shown, this is the seventh embodiment of the microwave circulator housing assembly 100 of the present application. In the seventh embodiment, a slot 123 is formed by the side wall 12 being recessed along the circumferential direction of the outer peripheral surface of the housing 1 above the side edge of the notch 122. The slot 123 communicates with the notch 122 along the circumferential direction of the outer peripheral surface of the housing 1. The relief cavity 120 is formed by the slot 123, or the relief cavity 120 is jointly formed by the slot 123 and the notch 122. The hanging platform structure 121 is a cantilever structure with one end connected to the side wall 12.

[0068] Please refer to Figure 15 and Figure 16 As shown (seventh embodiment), along the circumferential direction of the outer peripheral surface of the housing 1, a stop groove 124 is formed by the middle position of the upper edge of the side wall 12 being recessed downward. The body portion 21 is located inside the side wall 12. The cover plate 2 further includes a protrusion 22 formed by protruding outward along the edge of the body portion 21. The protrusion 22 is correspondingly fitted into the stop groove 124 of the side wall 12. The outer edge position of the protrusion 22 further extends along the circumferential direction of the outer peripheral surface of the housing 1 to form a limiting portion 221. The limiting portion 221 is fitted on the outer side surface of the side wall 12, and the side wall 12 is limited between the limiting portion 221 and the outer edge of the main body portion 21 to limit the outward expansion of the side wall 12.

[0069] Please refer to Figures 9 to 14 As shown (fourth, fifth, and sixth embodiments), the cover plate 2 further includes a protrusion 22 formed by protruding outward along the edge of the body portion 21. The protrusion 22 is correspondingly fitted into the notch 122 of the side wall 12. The outer edge position of the protrusion 22 further extends along the circumferential direction of the outer peripheral surface of the housing 1 to form a limiting portion 221. The limiting portion 221 is fitted on the outer side surface of the side wall 12, and the side wall 12 is limited between the limiting portion 221 and the outer edge of the main body portion 21 to limit the outward expansion of the side wall 12.

[0070] In the present application (including seven embodiments), the inner bottom surface 201 of the clamping groove 20 correspondingly interferes with the hanging platform structure 121 in the up and down direction. Along the up and down direction, the height of at least a partial area of the inner bottom surface 201 from the edge of the cover plate 2 inward shows an increasing trend. With such a design, during the entire process of the mold core extruding the crossbeam structure 125 to form the hanging platform structure 121, the interference holding force / pressure between the hanging platform structure 121 and the clamping groove 20 also shows an increasing trend, making the holding more stable. Further, preferably, the inner bottom surface 201 is planar, and the included angle between the inner bottom surface 201 and the horizontal plane is greater than 0 degrees and less than 15 degrees. Further, more preferably, the included angle between the inner bottom surface 201 and the horizontal plane is 7 degrees. After multiple experimental verifications, when the included angle is within the range of the present application, the interference fixation is more stable, and the situation that the hanging platform structure 121 is damaged by hard extrusion will not occur.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
