[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] In the description of the present invention, 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 can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the description of the present invention, it should be understood that the terms "including" and "having" and any variations thereof used herein are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0032] like Figures 1 to 5 As shown, a first embodiment of an annular device housing assembly 100 of the present invention is shown. An annular device assembly (not shown) is encapsulated in the annular device housing assembly 100 to form an annular device. The annular device is used for communication equipment in mobile communication technology and is used to be installed on a mainboard (not shown) of the communication equipment. The annular device housing assembly 100 is generally cylindrical in shape. The annular device housing assembly 100 includes a housing 20 for accommodating the annular device assembly (not shown) and a cover plate 40 for encapsulating the annular device assembly in the housing 20. The housing 20 includes a bottom wall 22 and a side wall 24 surrounding the bottom wall 22 and extending above the bottom wall 22. The side wall 24 and the bottom wall 22 together form a cavity (not numbered). The side wall 24 is provided with a plurality of notches 241 from top to bottom. The annular device assembly has a plurality of connection pins (not shown) for connecting to the mainboard of the communication equipment. After the annular device assembly is installed in the cavity from top to bottom, the connection pins are exposed from the corresponding notches 241. The outer contour diameter of the annular device housing 20 in this embodiment is 7 mm, but it does not exclude that the diameter may be set to a size close to 7 mm, such as 10 mm, 8 mm, or even 6 mm.

[0033] In this embodiment, the cover plate 40 includes a main body 41 that is roughly disc-shaped and a protrusion 42 that protrudes outward along the edge of the main body 41. The two sides of the protrusion 42 connected to the main body 41 are recessed inward to form an engagement groove 421. After the cover plate 40 is covered on the housing 20, the protrusion 42 is inserted into the notch 241, and at the same time, the edge of the side wall 24 is inserted into the engagement groove 421 to prevent the side wall 24 from expanding outward along the axis of the housing 20.

[0034] In this embodiment, a mutually interlocking fixing structure is provided between the side wall 24 and the cover plate 40. Specifically, the upper surface edge of the main body 41 of the cover plate 40 is recessed downward at a position other than the protrusion 42 to form a hanging platform structure 43, and a hook structure 242 is formed at a corresponding position on the upper edge of the side wall 24 of the shell 20. After the cover plate 40 is covered on the shell 20, the hook structure 242 is correspondingly held above the hanging platform structure 43 to limit the cover plate 40 from being separated upward from the shell 20. Specifically, after the cover plate 40 is covered on the shell 20, a mold core 50 ( Figure 4The hook structure 242 is formed by extruding the outer position of the upper edge of the side wall 24 from top to bottom (as shown). The cover plate 40 is supported by an annular device assembly (not shown) assembled into the shell 20. Of course, in other embodiments, the hook structure 242 can also be formed by a mold core 50 extruding the outer position of the upper edge of the side wall 24 along the radial direction of the shell 20 (from outside to inside), and it is generally in the form of a barb-shaped structure protruding toward the cavity side. In this embodiment, the hanging platform structure 43 is located in the middle position of the upper surface edge of the main body 41 between two adjacent protrusions 42.

[0035] The cover plate 40 is limited with the housing 20 by engaging with the hook structure 242 corresponding to the hanging platform structure 43, is not easy to get loose, does not use easily melted solder and easily volatile adhesive, can withstand high temperatures, and is easy to assemble.

[0036] Please refer to Figure 2 FIG. 2 is another embodiment of the housing 20 in the first embodiment of the present invention. In this embodiment, a bearing notch 243 is formed above the edge of the side wall 24 of the housing 20. When the cover plate 40 is covered on the housing 20, the cover plate 40 is correspondingly supported on the bearing notch 243, so that the cover plate 40 can be restricted from moving downward, especially when the mold core 50 squeezes the side wall 24 to form the hook structure 242. This can prevent the cover plate 40 from damaging the annular device assembly downward due to excessive squeezing force of the mold core 50.

[0037] like Figures 6 to 10 FIG. 1 is a second embodiment of an annular housing assembly 100 of the present invention. The annular housing assembly 100' in the second embodiment is similar in structure to the first embodiment, except that a depression 244' is formed downwardly at the upper end of the side wall 24' of the housing 20'. After the cover plate 40' is covered on the housing 20', the protrusion 42' of the cover plate 40' is correspondingly inserted into the depression 244', and at the same time, the part of the side wall 24' located on both sides of the depression 244' is inserted into the fitting groove 421', and the depression 244' and the protrusion 42' form an interference fit.

[0038] In the second embodiment, the recess 244' is set to be dovetail-shaped, wherein the recess 244' is narrower at a position close to the axis of the housing 20' and wider at a position away from the axis of the housing 20', and the position where the protrusion 42' cooperates with the recess 244' is also designed to be narrow inside and wide outside. The protrusion 42' can clamp the recess 244', thereby preventing the side wall 24' of the housing 20' from deforming outward. Of course, in order to more reliably prevent the side wall 24' from deforming outward, the second embodiment is designed with the same fitting groove 421' structure as the first embodiment.

[0039] In the second embodiment, the upper surface edge of the main body 41' of the cover plate 40' is recessed downward at the positions adjacent to the protrusion 42' to form the hanging platform structure 43', and the upper edge of the side wall 24' of the shell 20' is formed with a hook structure 242' at a corresponding position. Similar to the first embodiment, when the cover plate 40' is covered on the shell 20', the hook structure 242' is correspondingly buckled above the hanging platform structure 43' to limit the cover plate 40' from detaching upward from the shell 20'. The formation method of the hook structure 242' is the same as that of the first embodiment, and the function and technical effect achieved are also basically the same, which will not be repeated.

[0040] In the first and second embodiments, the protrusions 42 of the cover plate 40 protrude outwardly from the side wall 24 along the radial direction of the shell 20. In some special cases, when the cover plate 40 needs to be removed, while the shell 20 is fixed, it is only necessary to use a push pin (not shown) to push the lower surface of the part of the protrusion 42 located on the outside of the side wall 24 from bottom to top and apply a thrust upward to achieve removal. However, in some special use occasions or specifications, the cover plate 40 is not allowed to extend beyond the side wall 24 (or because the length of the cover plate 40 extending beyond the side wall 24 is not enough), so it becomes difficult to remove the cover plate 40. Therefore, based on the first and second embodiments, the present invention also discloses a third embodiment, please refer to the specific embodiment. Fig.10 and Fig.11 .

[0041] In the third embodiment, a clearance groove 245" is formed on the outer surface of the side wall 24" of the annular device housing assembly 100". The clearance groove 245" is located directly below the cover plate 40" and extends along the entire length of the housing 20" in the up-down direction. When the cover plate 40" needs to be removed, while the housing 20" is fixed, it is only necessary to use a push pin (not shown) to push against the lower surface of the protrusion 42" of the side wall 24" from bottom to top and apply an upward thrust to achieve removal. The clearance groove 245" is designed to make way for the push pin for removing the cover plate 40". In this way, even if the outer periphery of the cover plate 40" is designed not to exceed the outer periphery of the housing 20", the cover plate 40" can be easily removed.

[0042] It should be noted that the different structures of the annular housing assembly 100 disclosed in the various embodiments of the present invention can be used interchangeably and do not correspond to only one embodiment.

[0043] Please combine Figures 1 to 11 The following is a detailed description of the assembly and disassembly method of the cover plate 40 of the annular device housing assembly 100 of the present invention. The assembly comprises the following steps: A, the cover plate 40 is placed on the housing 20 assembled with the annular device assembly; B, at least one mold core 50 ( Figure 4As shown in FIG. 1 , the outer position of the upper edge of the side wall 24 is pressed downward from top to form the hook structure 242, and the hook structure 242 is correspondingly buckled on the top of the hanging platform structure 43. The assembly of the cover plate 40 is completed.

[0044] In the present invention, in the first and second embodiments, the lower surface of the portion of the protrusion 42 protruding out of the outer wall surface of the side wall 24 is defined as a disassembly functional area 447. In the third embodiment, at least the lower surface portion of the protrusion 42 located directly above the clearance groove 245 is defined as a disassembly functional area 447. To disassemble the cover plate 40, multiple jigs with columnar ejector pins at the head are required. The specific method is as follows: A, multiple jigs are pressed from bottom to top against the disassembly functional area 447; B, multiple jigs are pressed from top to bottom against the upper end surface of the side wall 24; C, the corresponding jigs are pushed by a large thrust force so that the hook structure 242 is detached from the hanging platform structure 43 to separate the cover plate 40 from the shell 20.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, 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 invention.
