[0002] Shielding covers are mainly used in electronic products such as mobile phones and GPS to prevent electromagnetic interference and shield electronic components on PCBs (Printed Circuit Boards).

[0003] In the process of connecting the shielding cover to the PCB board, the cost and production cycle should be comprehensively considered under the premise of facilitating maintenance and ensuring reliable connection.

[0004] In the prior art, a traditional shielding cover is usually divided into a shielding frame and an upper cover, and the shielding frame and the upper cover are detachably fastened together. This connection method can facilitate subsequent maintenance and also ensure a reliable connection between the shielding frame and the upper cover.

[0005] However, in the process of connecting the shielding cover to the PCB board, the traditional shielding cover still has some defects:

[0006] (1) Since the shielding frame and the upper cover are connected by snap-fit ​​connection, the process cost and manufacturing cost of the shielding frame and the upper cover are high;

[0007] (2) Since the corresponding snap-fit ​​components need to be processed in the shielding frame and the upper cover, the production cycle of the traditional shielding cover is relatively long. Utility Model Content

For example, "connection" can be a fixed connection or a detachable connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; "fixation" can be bolt fixation, snap fixation or glue fixation; the terms "first", "second" and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated; thus, the features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features; "multiple" or "several" means two or more; in addition, "and / or" includes any and all combinations of one or more related listed items; for ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to the specific circumstances.

[0045] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] In this embodiment, the specific implementation of the "shielding cover" is not limited, and those skilled in the art may selectively use any appropriate implementation method according to actual needs.

[0047] Figure 1 The present invention is an exploded schematic diagram of a shielding cover provided in an embodiment of the present invention being connected to a PCB board. Figure 2 A schematic cross-sectional view of a shielding cover provided in an embodiment of the utility model when connected to a PCB board. Figure 3 The embodiment of the utility model provides Figure 2 A partial enlarged view at point A.

[0048] See also Figure 1-Figure 3 The shielding cover 100 is arranged on a PCB board 200 having a plurality of electronic components and can cover at least one electronic component; the above-mentioned shielding cover 100 includes: a shielding cover frame 1, an adhesive 2, an insulating film 3 and a shielding cover body 4.

[0049] The shielding cover frame 1 is fixed on the PCB board 200 .

[0050] In addition, an insulating film 3 is attached to one surface of the adhesive member 2 , and the adhesive member 2 is adhered to an end of the shielding case frame 1 away from the PCB board 200 .

[0051] It should be noted that the other surface of the adhesive member 2 is bonded to the cover of the shielding cover 100 , so that the cover of the shielding cover 100 is detachably connected to the frame of the shielding cover 100 .

[0052] In some embodiments, Figure 1 As shown, the cover of the shielding cover 100 is an aluminum foil sheet.

[0053] In some embodiments, Figure 1 As shown, the adhesive member 2 is a double-sided adhesive.

[0054] Among them, the double-sided adhesive tape has high temperature resistance; the above-mentioned aluminum foil sheet and the above-mentioned double-sided adhesive tape are both in the form of long strips with a preset length and a preset width.

[0055] Figure 4 This is a schematic diagram of the breakdown of a traditional shielding cover connected to a PCB board.

[0056] Specifically, combined Figure 1-Figure 4 It can be seen that in the process of connecting the shielding cover to the PCB board, the traditional shielding cover 300 is usually divided into a shielding frame 3001 and an upper cover 3002, and the upper cover 3002 is detachably connected to the shielding frame 3001 through a snap-fit ​​component 3003; while the present shielding cover 100 adopts a shielding cover frame 1 to replace the shielding frame 3001 in the traditional shielding cover 300, and adopts a shielding cover cover body 4 (aluminum foil) to replace the upper cover 3002 in the traditional shielding cover 300, and then the snap-fit ​​connection formed between the shielding frame 3001 and the upper cover 3002 is replaced by the adhesive connection formed between the shielding cover cover body 4 and the shielding cover frame 1 through the adhesive 2 (double-sided tape).

[0057] To summarize, since the shielding frame 3001 and the upper cover 3002 in the traditional shielding cover 300 are connected by snapping, the process cost and manufacturing cost of the shielding frame 3001 and the upper cover 3002 are relatively high; while the shielding cover cover body 4 and the shielding cover frame 1 in the present shielding cover 100 are connected by adhesion, which not only can realize a detachable connection between the two, but also can reduce the process cost and manufacturing cost.

[0058] It should be noted that in the traditional shielding cover 300, since the corresponding snap-fit ​​components 3003 need to be processed in the shielding frame 3001 and the upper cover 3002, this will result in a longer production cycle for the traditional shielding cover 300; while in the present shielding cover 100, the shielding cover cover body 4 can be detachably assembled to the shielding cover frame 1 through the adhesive 2 (double-sided tape), so it is only necessary to cut out the adhesive 2 (double-sided tape) with a preset length and a preset width to complete a production cycle; compared with the traditional shielding cover 300, the present shielding cover 100 has the advantage of a short production cycle.

[0059] Figure 5 A schematic structural diagram of a shielding cover frame provided in an embodiment of the utility model.

[0060] In some embodiments, according to Figure 1 , Figure 3 and Figure 5 It can be known that the frame of the shielding cover 100 includes: a vertical frame 11 and a support plate 12 .

[0061] It can be understood that a cavity 1101 is formed inside the vertical frame 11 for accommodating at least one electronic component on the PCB board 200 .

[0062] Specifically, the support plate 12 is covered on the vertical frame 11 to support the adhesive component 2 and the cover body of the shielding cover 100 .

[0063] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 One surface of the adhesive 2 with the insulating film 3 is bonded to the support plate 12, and the other surface of the adhesive 2 facing away from the insulating film 3 is bonded to the shielding cover body 4, so that the shielding cover body 4 can be detachably connected to the shielding cover frame 1.

[0064] In some embodiments, Figure 1-Figure 3 As shown, the support plate 12 is provided with an opening 1201 ; the outer edge shape of the insulating film 3 is adapted to the shape of the opening 1201 .

[0065] In the embodiment of the present application, when the adhesive member 2 is bonded to the support plate 12 , the insulating film 3 may fill the opening 1201 .

[0066] In some embodiments, see Figure 5 The vertical frame 11 includes: a pair of first side walls 111 and a pair of second side walls 112 .

[0067] The pair of first side walls 111 and the pair of second side walls 112 together enclose a cavity 1101 .

[0068] In addition, a pair of first side walls 111 extend along a first direction 1001 , and a pair of second side walls 112 extend along a second direction 1002 .

[0069] In addition, a pair of first side walls 111 are respectively disposed at two ends of the second side wall 112 that are away from each other in the second direction 1002 .

[0070] Furthermore, the first direction 1001 and the second direction 1002 are orthogonal to each other.

[0071] In some embodiments, in combination Figure 1 , Figure 3 and Figure 5 It can be seen that the vertical frame 11 has a first end 1102 and a second end 1103 opposite to each other in the third direction 1003 .

[0072] It can be understood that the first end 1102 of the vertical frame 11 is connected to the surface of the PCB board 200 ; and the support plate 12 is covered on the second end 1103 of the vertical frame 11 .

[0073] It should be noted that the third direction 1003 , the second direction 1002 and the first direction 1001 are orthogonal to each other.

[0074] In some embodiments, according to Figure 2 , Figure 3 and Figure 5 When the cover of the shielding cover 100 is fixed on the frame of the shielding cover 100 , the cavity 1101 is closed so that at least one electronic component accommodated in the cavity 1101 is covered by the shielding cover 100 .

[0075] In some embodiments, in combination Figure 1-Figure 5 It can be known that the double-sided adhesive tape has an adhesive force that prevents the cover body of the shielding cover 100 and the frame of the shielding cover 100 from being separated from each other.

[0076] Specifically, the cover of the shielding cover 100 responds to the application of external force to overcome the adhesion force, forcing the cover of the shielding cover 100 and the frame of the shielding cover 100 to separate from each other.

[0077] In summary, the shielding cover provided in the embodiment of the utility model adopts adhesives to achieve adhesion connection, thereby replacing the snap-fit ​​connection adopted by the traditional shielding cover; compared with the traditional shielding cover, the shielding cover can effectively reduce costs and shorten production cycles while facilitating maintenance and ensuring reliable connection. Therefore, the shielding cover provided in the embodiment of the utility model has certain novelty compared with the traditional shielding cover.

[0078] The above contents are further detailed descriptions of the present invention in combination with specific / preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
