Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic devices, and in particular, to an elastic component and an electronic device. Background Art

[0002] With the development of technology, electronic devices such as smart phones and tablet computers are becoming increasingly important in people's lives. There are many components inside an electronic device, and stable conductive connections are often required between these components to meet requirements such as resistance and stability. Currently, conductive shrapnel is often arranged inside the electronic device to achieve conductive connections between some components. At this time, the shrapnel, as a conductive medium for different media or electronic circuits, can be used to achieve electrical signal connections, antenna connections, or grounding connections, etc. Therefore, a variety of different shrapnels are derived in various scenarios. For example, surface-mounted shrapnels, break-board shrapnels, etc.

[0003] Taking the break-board shrapnel as an example, a traditional break-board shrapnel needs to sink the middle frame to set the shrapnel, and it is very difficult to sink and achieve break-board grounding when the middle frame is relatively thin. If you don't want to occupy the space under the circuit board but still need to set the shrapnel, you have also tried to set the shrapnel on the surface of the circuit board, but this will inevitably occupy a large area on the surface of the circuit board, which is not conducive to the miniaturization of electronic devices, etc.

[0004] Therefore, there is an urgent need to provide a break-board shrapnel and its installation method to solve the above problems. Summary of the Invention

[0005] The embodiments of the present application provide an elastic component and an electronic device. The elastic component is not arranged on the circuit board, can not occupy the space on the circuit board, and can still achieve good electrical connection with the first component, effectively improving the utilization rate of the circuit board, and reducing or avoiding damage to the first component. It is simple and easy to implement, and thus the performance of the electronic device is better.

[0006] To achieve the above object, the embodiments of the present application adopt the following technical solutions:

[0007] In a first aspect, an elastic component is provided. The elastic component is applied to an electronic device. The electronic device further includes a circuit board and a first component. The circuit board has a first surface and a second surface facing away from the first surface. The elastic component is arranged on the first surface, and the first component is arranged on the second surface. The circuit board further has a first through hole penetrating the first surface and the second surface. Part of the elastic component is embedded in the first through hole, and part of the first component is also embedded in the first through hole. The part of the elastic component embedded in the first through hole is electrically connected to the part of the first component embedded in the first through hole.

[0008] An embodiment of the present application provides an elastic component. The elastic component is not disposed on the circuit board but can still achieve electrical connection with the first component. This can not only save the space on the circuit board and effectively improve the utilization rate of the circuit board, but also does not require the first component to be changed, such as sunken, thereby reducing or avoiding damage to the first component. At the same time, some elastic components and some first components can achieve good electrical connection in the first through hole, and it is convenient to manufacture.

[0009] In a possible implementation manner of the first aspect, the elastic component is applied to an electronic device. The electronic device further includes a circuit board and a first component. The circuit board has a first surface and a second surface facing away from the first surface. The elastic component is disposed on the first surface, and the first component is disposed on the second surface. The circuit board further has a first through hole penetrating the first surface and the second surface. A part of the elastic component is embedded in the first through hole, and the first component is not embedded in the first through hole. The part of the elastic component embedded in the first through hole is electrically connected to the first component.

[0010] In this implementation manner, the elastic component is not disposed on the circuit board but can still achieve good electrical connection with the first component. This can not only save the space on the circuit board and effectively improve the utilization rate of the circuit board, but also does not require the first component to be changed, such as sunken, thereby reducing or avoiding damage to the first component. At the same time, after some elastic components extend into the first through hole, they can achieve good electrical connection with the first component outside the first through hole, and it is simple and easy to implement.

[0011] In a possible implementation manner of the first aspect, the body of the shielding cover has a fifth surface and a sixth surface facing away from the fifth surface. The fifth surface is used to face the first surface when the shielding cover is mounted on the first surface of the circuit board. The fixing part of the conductive elastic sheet is fixed on the fifth surface; the body further has at least one positioning hole penetrating the fifth surface and the sixth surface. The positioning hole also penetrates the fixing part of the conductive elastic sheet and is used to position the fixing part and the body. At least one connection point is further provided in the fixing part, and the connection point is used to connect the fixing part and the body; the body further has at least one fixing leg, one end of the fixing leg is connected to the body and the other end is connected to the first surface.

[0012] In this implementation manner, through the grounding scheme of spot welding the conductive elastic sheet on the shielding cover, the conductive elastic sheet is disposed on the shielding cover, which does not require occupying the surface space of the circuit board, improves the utilization rate of the circuit board, and the middle frame does not need to sink, saving the space of the middle frame under the circuit board and the space of the board. It also enables the shielding cover to complete the protection of other electronic components located below the shielding cover while achieving electrical connection; and, the conductive elastic sheet and the shielding cover are spot welded and positioned through the positioning hole, which is simple and easy to operate.

[0013] In a possible implementation of the first aspect, the circuit board further has at least one second through hole penetrating the first surface and the second surface, and the body further has at least one pin. One end of the pin is connected to the body, and the other end is embedded in the second through hole.

[0014] In this implementation, by adding pins on both sides of the shielding cover, the bonding force between the shielding cover and the circuit board is enhanced, and thus the stable connection between the conductive elastic sheet and the middle frame is also achieved.

[0015] In a possible implementation of the first aspect, the conductive elastic sheet includes a fixing part and a connecting part. The fixing part is fixed on the third surface of the bracket; one end of the connecting part communicates with the part of the fixing part that does not contact the bracket, and the other end of the connecting part is movable relative to the fixing part. The connecting part is used for partially embedding into the first through hole and electrically connecting with the first component when the bracket is installed on the first surface.

[0016] In this implementation, the conductive elastic sheet achieves good electrical connection with the first component through the connecting part, and can be fixed on the bracket through the fixing part, which is simple and easy to implement.

[0017] In a possible implementation of the first aspect, the fixing part is fixed on the fifth surface of the shielding cover. The fixing part is used for facing the first surface when the shielding cover is installed on the first surface of the circuit board; the connecting part has a first sub-bending section, a second sub-bending section, a force arm section, and a pruning section connected in sequence. The first sub-bending section communicates with a side surface of the fixing part that does not contact the shielding cover and is connected to the force arm section through the second sub-bending section. The first sub-bending section also bends away from the pruning section and does not contact the side of the fixing part facing away from the shielding cover. The second sub-bending section is approximately parallel to the side of the fixing part facing away from the shielding cover; the force arm section inclines away from the fixing part. The force arm section is used for at least partially embedding into the first through hole when the shielding cover is installed on the first surface, and the part of the force arm section embedded in the first through hole is electrically connected to the middle frame; one end of the pruning section is slidable relative to the fixing part. The pruning section is used for not contacting the fixing part first and then sliding to abut against the fixing part when the shielding cover is installed on the first surface to conduct the middle frame and the conductive elastic sheet.

[0018] In this implementation, the conductive elastic sheet is arranged on the shielding cover, so it does not need to occupy the surface space of the circuit board, effectively improving the utilization rate of the circuit board, and there is no need for the middle frame to sink, which can save the space of the middle frame under the circuit board and the board space.

[0019] In a possible implementation of the first aspect, the connecting part further has a contact part. The contact part is arranged on the side of the force arm section facing away from the fixing part and protrudes. The contact part is used for at least partially embedding into the first through hole and electrically connecting with the middle frame when the shielding cover is installed on the first surface.

[0020] In this implementation, the conductive spring contacts the middle frame through the protruding ball head connector, especially when it contacts the cylindrical structure, the electrical connection will be more stable, and through the middle frame laser engraving grounding solution, the board breaking area only needs to be about 3.2mm 2 The broken plate area can be reduced by about 70% compared with the related art, which greatly improves the stability.

[0021] In a possible implementation of the first aspect, the PCB has a first surface, a second surface away from the first surface, a first through hole penetrating the first surface and the second surface, and three second through holes penetrating the first surface and the second surface; the shielding cover has a first body of a rectangular parallelepiped and a second body of a rectangular parallelepiped, the volume of the first body is greater than the volume of the second body, the first body has a first long side, a first short side, a second long side and a second short side connected in sequence, the second body has a third long side, a third short side, a fourth long side and a fourth short side connected in sequence, the first long side is connected to the third long side, a fixing foot is welded on the first short side, and a fixing foot is welded on the second short side , two pins arranged at intervals are welded on the second long side, and one pin is welded on the fourth long side; the conductive spring sheet includes a fixed part, a first sub-bending section, a second sub-bending section, a force arm section, a pruning section and a convex ball connected in sequence, the first sub-bending section is bent in a direction away from the pruning section and does not contact the side of the fixed part away from the shielding cover, the second sub-bending section is parallel to the side of the fixed part away from the shielding cover, the force arm section is inclined in a direction away from the fixed part, one end of the pruning section is slidable relative to the fixed part, and the convex ball is arranged on the force arm section; the middle frame has a cylindrical structure and a middle frame base; two positioning holes are respectively arranged on the first cuboid, and two positioning holes are respectively arranged on the fixed part.

[0022] In this implementation, the shielding cover and the fixing part are inserted into the clamp in sequence, the shielding cover and the conductive spring sheet are positioned, and then spot welding is performed at the connection points to allow the conductive spring sheet to be spot welded on the shielding cover 4; then, the shielding cover is turned over so that the fifth surface faces the first surface of the PCB, the two fixing feet on the shielding cover are spot welded on the first surface, and the three pins on the shielding cover are inserted into the second through hole and soldered to the PCB, thereby fixing the shielding cover; then, the conductive spring sheet is forcefully inserted into the first through hole, at which time the pruning section slides to abut against the fixing part, and the convex ball is embedded in the first through hole, and then the cylindrical structure in the middle frame is embedded in the first through hole to contact the convex ball to achieve electrical connection.

[0023] In a second aspect, an electronic device is provided, comprising an elastic component as in the first aspect or any possible implementation of the first aspect.

[0024] The embodiments of the present application provide an electronic device that can be miniaturized, lightweight, and has good performance.

[0025] An embodiment of the present application provides an elastic component. This elastic component is not disposed on the circuit board, can avoid occupying the space on the circuit board, and still can achieve good electrical connection with the first component, effectively improving the utilization rate of the circuit board and reducing or avoiding damage to the first component. It is simple and easy to implement. When applied to an electronic device, the electronic device can achieve miniaturization and thinness, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0053] Next, the application scenarios of the present application and the shrapnel in related technologies will be introduced to facilitate a clearer understanding of the embodiments of the present application.

[0054] The embodiments of the present application provide an electronic device, and no specific restrictions are imposed on the specific type of the electronic device here.

[0056] The embodiments of the present application do not limit the specific forms of the above-mentioned electronic devices. For the convenience of description, the following embodiments are all exemplified by taking the electronic device as a mobile phone.

[0057] Please refer to Figure 1 and Figure 2 , Figure 1 which is an overall schematic diagram of an electronic device applicable to some embodiments of the present application, Figure 2 is Figure 1 a split schematic diagram of the electronic device shown in Figure 1 and Figure 2 The electronic devices shown in

[0058] In Figure 1 and Figure 2 's examples, the electronic device can include a display screen 100, a middle frame 101, a rear shell 102, a circuit board assembly 103, a battery 104, etc. It can be understood that Figure 1 and Figure 2 and the related drawings in the following text only schematically show some components in the electronic device, and the actual shapes, sizes, positions, structures, etc. of these components are not limited byFigure 1 and Figure 2 and the definitions in the accompanying drawings hereinafter.

[0059] The following further elaborates on the specific structure of the electronic device applicable to the embodiments of the present application.

[0060] Please refer to Figure 1 and Figure 2 . Taking the mobile phone 01 as an example of the electronic device, the mobile phone 01 may include a display screen 100 and a middle frame 101, and the display screen 100 is located on one side of the middle frame 101.

[0061] In applications, the display screen 100 can be used to display images, videos, etc. It should be noted that the display screen 100 can be any one of a liquid crystal display (LCD), an organic light emitting diode (OLED) display screen, a mini light emitting diode (Mini LED) display screen, a micro light emitting diode (Micro LED) display screen, etc.

[0062] In Figure 1 the illustrated embodiment, the shape of the electronic device can be a rectangular flat plate. Of course, the shape of the electronic device can also be any other shape, specifically subject to actual applications.

[0063] Please refer to Figure 2 . The mobile phone 01 further includes a rear case 102, a circuit board assembly 103, a battery 104 and other structures.

[0064] Among them, the rear case 102 can be arranged on the side of the middle frame 101 away from the display screen 100; and, an internal accommodation space of the mobile phone 01 can be formed between the rear case 102 and the middle frame 101, and structures such as the circuit board assembly 103 and the battery 104 can be accommodated in the internal accommodation space. The battery 104 can be used to supply power to structures such as the display screen 100 and the circuit board assembly 103 in the mobile phone 01.

[0065] Another example is Figure 2 as shown. The circuit board assembly 103 can include a main circuit board 1031 and electronic components 1032, etc.

[0066] Among them, the main circuit board 1031 can be used to carry the electronic components 1032 and complete signal interaction with the electronic components 1032.

[0067] Figure 2For example, the circuit board assembly 103 includes two electronic components 1032. Of course, the number of electronic components 1032 is not limited to two, and it depends on the actual application.

[0068] It should be understood that the main circuit board 1031 may include a printed circuit board (PCB), a flexible printed circuit (FPC), etc.

[0069] It should be understood that the electronic components 1032 may include, but are not limited to, chips, resistors, capacitors, inductors, potentiometers, electron tubes, radiators, electromechanical components, connectors, semiconductor discrete devices, sensors, power supplies, switches, micro motors, electronic transformers, relays, subscriber identity module (SIM) card holders, etc.

[0070] In addition, the above mobile phone 01 may further include other structures such as a microphone, a speaker, a camera, etc., which will not be specifically described here.

[0071] In actual application, the above main circuit board 1031 can be electrically connected to components such as the middle frame 101 through elastic pieces.

[0072] The following provides two setting methods for the main circuit board 1031, the elastic piece, and the middle frame 101 in the related art.

[0073] As an example, Figure 3 shows a conventional broken board elastic piece grounding structure.

[0074] As Figure 3 shown, the electronic device 02 includes a main circuit board 1031 and a middle frame 101. The main circuit board 1031 has two grooves penetrating the upper surface and the lower surface of the main circuit board 1031 ( Figure 3 not shown in the figure). A part of the middle frame 101 is located below the lower surface of the main circuit board 1031. Thus, the middle frame 101 located below the grooves can form two accommodation spaces with the two grooves, and each accommodation space is provided with a first elastic piece 201. In addition, two reed pieces 202 are provided on the middle frame 101. Each reed piece 202 is welded to the middle frame 101 through a reed piece solder joint 203. Each reed piece 202 is correspondingly arranged with a first elastic piece 201, and the first elastic piece 201 is electrically connected to the reed piece 202 through its own elastic point ( Figure 3 not shown in the figure), thereby realizing the electrical connection between the main circuit board 1031 and the middle frame 101.

[0075] However, in combination with Figure 3As can be seen, in the above structure, the working height of the upper surface b1 of the first elastic piece 201 will exceed the height of the upper surface (TOP surface) of the main circuit board 1031. At this time, the middle frame 101 needs to sink to complete the electrical connection. With the development of technology, electronic devices pursue miniaturization and thinness. Then, in the case of thinning the whole machine, for example, in the overlapping area between the universal serial bus (USB) small board and the inner screen device area, the wall thickness of the middle frame 101 below the TOP surface is only about 0.3 mm, and the middle frame 101 is very thin. If the middle frame 101 is further thinned, risks such as perforation may occur. For the purpose of waterproofing, etc., the middle frame 101 here cannot have a hole. Therefore, it is very difficult to achieve broken-board grounding by sinking the middle frame 101 and ensure the integrity of the structure and performance of the middle frame 101.

[0076] As another example, Figure 4 illustrates a conventional broken-board elastic piece grounding structure.

[0077] As Figure 4 shown, the electronic device 02 includes a main circuit board 1031. The main circuit board 1031 has an upper surface (TOP surface). A second elastic piece 204 is arranged on the TOP surface. The second elastic piece 204 is positioned on the TOP surface through a positioning member 205. At the same time, the positioning member 205 is welded to the TOP surface through a positioning solder joint 206. Although the electrical connection of the second elastic piece 204 can be completed without occupying the space under the main circuit board 1031 at this time, it needs to occupy a large area of the TOP surface of the main circuit board 1031. For example, it may need to occupy at least an area of 11 mm 2 or so on the TOP surface, resulting in the electronic device being unable to achieve miniaturization and thinness.

[0078] It should be noted that Figure 3 and Figure 4 the dashed boxes in are due to not drawing the entire structure of the electronic device, but only exemplarily drawing a part of the structure related to the invention point. Then, the part within the dashed box is a partial structure diagram, and the boundary is represented by a dashed line.

[0079] Then, based on the above two examples, it can be seen that the elastic pieces provided in the related art cannot ensure the requirements such as the setting of the middle frame and the miniaturization and thinness of the electronic device.

[0080] In view of this, the embodiment of the present application provides an elastic component. The elastic component is not arranged on the circuit board, can not occupy the space on the circuit board, and can still achieve a good electrical connection with the first component, effectively improving the utilization rate of the circuit board and reducing or avoiding the damage of the first component, which is simple and easy to implement.

[0081] When the elastic component of the present application is applied to an electronic device, the electronic device can be miniaturized and thinned, and has good performance.

[0082] The following will combine Figures 5 to 13 to introduce in detail the elastic component 3 and the electronic device 02 provided by the embodiments of the present application.

[0083] As Figures 5 to 13 shown, the electronic device 02 provided by the embodiments of the present application includes: a circuit board 1, a first component, and an elastic component 3. Among them, the circuit board 1 has a first surface m1 and a second surface m2 facing away from the first surface m1. The elastic component 3 is disposed on the first surface m1, and the first component is disposed on the second surface m2. The circuit board 1 also has a first through hole k1 penetrating the first surface m1 and the second surface m2. Part of the elastic component 3 is embedded in the first through hole k1, and part of the first component is also embedded in the first through hole k1. The part of the elastic component 3 embedded in the first through hole k1 is electrically connected to the part of the first component embedded in the first through hole k1.

[0084] In applications, the above circuit board may include a PCB, an FPC, etc. The following embodiments are all described by taking the circuit board as a PCB as an example.

[0085] The above first component may refer to a structure that needs to be electrically connected to the circuit board. For example, a middle frame, a camera module, etc. The position, size, etc. of the first component can be determined according to actual needs. The following embodiments are all described by taking the first component as a middle frame as an example.

[0086] The embodiments of the present application do not limit the specific structure of the middle frame. Exemplarily, when part of the elastic component is embedded in the first through hole and part of the first component is also embedded in the first through hole, as Figure 5 shown, the middle frame 101 may include a middle frame base and an embedded part. The middle frame base is located on the second surface m2 of the circuit board 1 and is not embedded in the first through hole k1 of the circuit board 1, and the embedded part is located in the first through hole k1; or, the middle frame may only be located on the second surface of the circuit board. At this time, part of the elastic component needs to be embedded in the first through hole and electrically connected to the middle frame.

[0087] In the case where the middle frame includes a middle frame base and an embedded part, the size, shape, etc. of the middle frame base can be determined according to the requirements of the electronic device, and the size, shape, etc. of the embedded part can be determined according to the size and shape of the first through hole, the size and shape of the part of the first component embedded in the first through hole, etc. Exemplarily, when the first through hole is a rectangular through hole, the part of the first component embedded in the first through hole and the embedded part can both be cubes, and as long as they can be embedded in the first through hole, so as to perform matching electrical connections; or, when the first through hole is a circular through hole, the part of the first component embedded in the first through hole and the embedded part can both be spheres, and as long as they can be embedded in the first through hole, so as to perform matching electrical connections.

[0088] In one or more embodiments of the present application, as Figures 5 to 13 shown, the elastic component 3 may include: a bracket and at least one elastomer. Among them, the bracket has a third surface and a fourth surface facing away from the third surface. When the bracket is installed on the first surface m1, the third surface faces the first surface m1, and a part of the bracket does not contact the first surface m1. At least one elastomer is disposed on the third surface. The elastomer is configured to partially embed into the first through hole k1 when the bracket is installed on the first surface m1, and the elastomer embedded in the first through hole k1 is electrically connected to the first component.

[0089] In the application, the above-mentioned elastomer may refer to a structure that has elasticity itself, can be compressed, and can play an electrical conduction role. For example, a conductive shrapnel, a conductive foam, a conductive silicone, etc. The following embodiments are all described by taking the elastomer as a conductive shrapnel as an example.

[0090] The number of the elastomers here can be one or more, and can be specifically determined according to the bracket area, antenna requirements, etc.

[0091] In the application, the above-mentioned bracket may refer to a structure that can play a supporting role. For example, a shielding cover, etc. The following embodiments are all described by taking the bracket as a shielding cover as an example.

[0092] There is no limitation on the specific material of the above-mentioned shielding cover. Exemplarily, the shielding cover may include a metal and an insulating paint wrapped on the surface of the metal. For example, the shielding cover may be composed of copper (Cu) and an insulating paint wrapped on the surface of Cu. When the shielding cover is installed on the PCB, the shielding cover is suspended above the first surface of the PCB, so as to protect the electronic components disposed on the PCB and located between the PCB and the shielding cover.

[0093] It should be noted that the area, position, etc. of the shielding cover in the embodiments of the present application can be determined according to the volume, position, etc. of the elastomer. After the shielding cover is positioned, the other electronic components below the shielding cover can be arranged according to needs.

[0094] In the application, there is no limitation on the specific connection manner between the above-mentioned conductive shrapnel and the shielding cover. Exemplarily, the conductive shrapnel can be partially welded to the shielding cover.

[0095] Furthermore, the conductive shrapnel can be partially spot-welded to the shielding cover, and the spot-welding process is simple and easy to implement.

[0096] In the application, the shape, size, etc. of the above-mentioned first through hole can be set according to the shape, volume, etc. of the part of the elastomer embedded in the first through hole, as long as it is ensured that the elastomer or the elastomer and the embedded part can be embedded therein. The elastomer or the elastomer and the embedded part can just be embedded in the first through hole and fill the first through hole completely; of course, it can also be that after the elastomer or the elastomer and the embedded part are embedded in the first through hole, there is still remaining space in the first through hole, and no specific limitation is made here.

[0097] For the elastic component provided by the embodiment of the present application, on the one hand, although the elastic component is not arranged on the circuit board, it can still achieve good electrical connection with the first component. In this way, it can neither occupy the space on the circuit board, effectively improving the utilization rate of the circuit board, nor does the first component need to be changed, such as sunken, reducing or avoiding damage to the first component; on the other hand, part of the elastic component and part of the first component are both embedded in the first through hole, so that good electrical connection can be achieved in the first through hole and it is convenient to manufacture. Thus, the electronic device applying this elastic component can be miniaturized and thinned, etc., and has good performance.

[0098] Please refer to Figures 5 to 13 , the electronic device 02 provided by the embodiment of the present application includes: a circuit board 1, a first component and an elastic component 3. Wherein, the circuit board 1 has a first surface m1 and a second surface m2 opposite to the first surface m1. The elastic component 3 is arranged on the first surface m1, and the first component is arranged on the second surface m2. The circuit board 1 also has a first through hole k1 penetrating through the first surface m1 and the second surface m2. Part of the elastic component 3 is embedded in the first through hole k1, and the first component is not embedded in the first through hole k1. The part of the elastic component 3 embedded in the first through hole k1 is electrically connected to the first component.

[0099] It should be noted that in the embodiment of the present application, part of the elastic component is embedded in the first through hole, while the middle frame is not embedded in the first through hole. Then, the height of the elastomer in the elastic component will become lower. Therefore, the first through hole needs to be made larger so that the elastomer can extend into the first through hole.

[0100] For the elastic component provided by the embodiment of the present application, on the one hand, although the elastic component is not arranged on the circuit board, it can still achieve good electrical connection with the first component. In this way, it can neither occupy the space on the circuit board, effectively improving the utilization rate of the circuit board, nor does the first component need to be changed, such as sunken, reducing or avoiding damage to the first component; on the other hand, after part of the elastic component extends into the first through hole, good electrical connection can be achieved with the first component outside the first through hole, and it is simple and easy to implement. Thus, the electronic device applying this elastic component can be miniaturized and thinned, etc., and has good performance.

[0101] Taking the elastomer as a conductive elastic sheet, the bracket as a shielding cover, and the first component as a middle frame as an example, a further description will be given below.

[0102] Optionally, as an implementable manner, as Figures 5 to 13 shown, the shielding cover 4 includes a body 41, the body 41 has a fifth surface m5 and a sixth surface m6 facing away from the fifth surface m5, and the fifth surface m5 is used to face the first surface m1 when the shielding cover 4 is mounted on the first surface m1 of the circuit board 1; the fixing portion 51 of the conductive elastic sheet 5 is fixed on the fifth surface m5.

[0103] The body 41 further has at least one positioning hole k2 penetrating through the fifth surface m5 and the sixth surface m6, the positioning hole k2 also penetrates through the fixing portion 51 of the conductive elastic sheet 5 and is used to position the fixing portion 51 and the body 41, and the portion of the fixing portion 51 other than the positioning hole k2 has at least one connection point L1, and the connection point L1 is used to connect the fixing portion 51 and the body 41.

[0104] The body 41 further has at least one fixing leg 6, one end of the fixing leg 6 is connected to the body 41 and the other end is connected to the first surface m1.

[0105] In application, the above-mentioned body can be an integral cubic structure. For example, the body can be an integral tetrahedron; or, the body can be formed by connecting a plurality of different bodies. In the case where the body is formed by connecting a plurality of different bodies, please refer to Figure 5 shown, the body 41 is formed by connecting a first body 411 and a second body 422. Specifically, one side of the first body 411 is connected to one side of the second body 412.

[0106] There is no specific limitation on the manner in which the fixing portion of the above-mentioned conductive elastic sheet is fixed on the fifth surface of the shielding cover. Exemplarily, the fixing portion can be welded on the fifth surface.

[0107] Further, the fixing portion can be spot-welded on the fifth surface, which is simple and easy to implement at this time.

[0108] In practical applications, please refer to Figures 5 to 13 , two positioning holes k2 penetrating through the fifth surface m5 and the sixth surface m6 can be first provided on the first body 411 of the shielding cover 4, then, two positioning holes k2 can be provided on the fixing portion 51 of the conductive elastic sheet 5, and then the shielding cover 4 and the fixing portion 51 are sequentially inserted on the fixture to position the shielding cover 4 and the conductive elastic sheet 5, and finally spot welding positioning is performed at the connection point L1, so that the conductive elastic sheet 5 is spot-welded on the shielding cover 4.

[0109] It should be noted that there is no specific limitation on the order of setting the positioning holes on the first body and the order of setting the positioning holes on the fixing portion. It can also be to set the positioning holes on the first body and the fixing portion respectively at the same time, or, it can also be to first set the positioning holes on the fixing portion and then set the positioning holes on the first body.

[0110] The shielding cover provided by the embodiment of the present application adopts a grounding scheme of spot welding conductive elastic sheets on the shielding cover. At this time, since the conductive elastic sheets are arranged on the shielding cover, it is not necessary to occupy the space on the upper surface of the circuit board, effectively improving the utilization rate of the circuit board. Moreover, the middle frame does not need to sink, which can save the space of the middle frame under the circuit board and the space of the board. It also enables the shielding cover to complete the protection of other electronic components located under the shielding cover while achieving electrical connection. In addition, the conductive elastic sheets are spot welded and positioned with the shielding cover through positioning holes, which is simple and easy to operate.

[0111] Furthermore, as Figures 5 to 13 shown, the circuit board 1 further has at least one second through hole k3 penetrating the first surface m1 and the second surface m2, and the body 41 of the shielding cover further has at least one pin (Dip pin) 7. One end of the pin 7 is connected to the body 41 and the other end is embedded in the second through hole k3.

[0112] In application, the number of the above pins can be one or more, which can be specifically determined according to the combination degree of the shielding cover and the circuit board. As an example, as Figure 7 shown, the number of the pins 7 is three.

[0113] It should be noted that each pin is embedded in the second through hole, but the pin does not protrude from the second through hole. At this time, the periphery of the pin is connected to the PCB board through soldering, so as to realize the fixation of the shielding cover.

[0114] Even further, please refer to Figure 7 , it can be set that the pin 7 and the fixed pin 6 are located on different sides of the body 41 of the shielding cover 4, so as to better realize the fixing function.

[0115] The shielding cover provided by the embodiment of the present application enhances the bonding force between the shielding cover and the circuit board by adding pins on both sides thereof, and further realizes the stable connection between the conductive elastic sheet and the middle frame.

[0116] Optionally, as an implementable manner, as Figures 5 to 13 shown, the conductive elastic sheet 5 includes a fixing portion 51 and a connecting portion 52. The fixing portion 51 is fixed on the fifth surface m5 of the shielding cover 4, and the fixing portion 51 is used to face the first surface m1 when the shielding cover 4 is installed on the first surface m1 of the circuit board 1.

[0117] The connecting portion 52 has a first sub-bending section 521, a second sub-bending section 522, a force arm section 523 and a pruning section 524 connected in sequence. Among them, the first sub-bending section 521 communicates with a side surface of the fixing portion 51 that does not contact the shielding cover 4 and is connected to the force arm section 523 through the second sub-bending section 522. The first sub-bending section 521 also bends in a direction away from the pruning section 524 and does not contact the side of the fixing portion 51 facing away from the shielding cover 4.

[0118] The second sub-bending section 522 is approximately parallel to a side of the fixing portion 51 facing away from the shielding cover 4 .

[0119] The arm section 523 is inclined in a direction away from the fixing portion 51 . When the shielding cover 4 is mounted on the first surface m1 , the arm section 523 is at least partially embedded in the first through hole k1 , and the portion of the arm section 523 embedded in the first through hole k1 is electrically connected to the middle frame 101 .

[0120] One end of the trimming section 524 is slidable relative to the fixing portion 51 . When the shielding cover 4 is mounted on the first surface m1 , the trimming section 524 is first out of contact with the fixing portion 51 and then slides to abut against the fixing portion 51 to conduct electricity between the middle frame 101 and the conductive spring sheet 5 .

[0121] In application, the fixing portion may be a cube. Further, the fixing portion may be a tetrahedron structure.

[0122] In application, due to the influence of factors such as the manufacturing process, the second sub-bending section and the side of the fixing portion facing away from the shielding cover are actually approximately parallel.

[0123] It should be noted that when the conductive spring is not installed on the shielding cover, and when the conductive spring is installed on the shielding cover but not embedded in the first through hole, the pruning section and the fixing part may or may not be adjacent to each other, and there is no electrical connection at this time. However, when the conductive spring needs to be embedded in the first through hole, a force will be applied to the conductive spring, and under this force, the conductive spring is compressed downward, forcing one end of the pruning section to slide and abut against the fixing part, and the two have a reliable electrical connection. In addition, if the conductive spring is no longer in contact with the circuit board, the force can disappear, and the pruning section and the fixing part may or may not be adjacent to each other.

[0124] Furthermore, the conductive spring in the embodiment of the present application can provide elastic force to electrically connect the middle frame to the PCB board through elastic action. Specifically, the positions where the conductive spring provides elastic force are mainly on both sides of the bend ( Figure 13 The middle circle can provide elastic force). At the same time, the pruning section can also provide certain support when pressed down under the force, but the main function of the pruning section is to protect the conductive spring piece so that the circle part does not deform excessively when bending.

[0125] The conductive spring provided in the embodiment of the present application is arranged on the shielding cover and is integrated with the shielding cover. The conductive spring does not occupy the surface space of the circuit board, effectively improving the utilization rate of the circuit board. There is no need to sink the middle frame, which can save the middle frame space under the circuit board and the board space.

[0126] Optionally, as an implementable approach, refer to Figures 5 to 13As shown, the connecting portion 52 further has a contact member 8. The contact member 8 is disposed on the side of the lever arm segment 523 away from the fixing portion 51 and protrudes. When the shielding cover 4 is mounted on the first surface m1, the contact member is at least partially embedded in the first through hole k1 and is electrically connected to the middle frame 101.

[0127] In application, the shape of the above contact member can be the same as or similar to the shape of the contact portion with the middle frame, so that the contact member can better match the middle frame, thereby achieving a more effective electrical connection.

[0128] As an example, as Figure 5 shown, the contact member can be a convex sphere. The embedded portion of the middle frame 101 embedded in the first through hole k1 is a cylindrical structure 1011. At least part of the convex sphere is embedded in the first through hole k1, and the remaining part of the cylindrical structure 1011 is embedded in the first through hole k1. The convex sphere embedded in the first through hole k1 and the cylindrical structure 1011 can achieve a better fitting connection.

[0129] Furthermore, laser engraving can be added to the surface of the cylindrical structure to better achieve electrical connection with the convex sphere.

[0130] As another example, as Figure 6 shown, the contact member can be a convex sphere. At least part of the convex sphere is embedded in at least part of the first through hole k1 and is electrically connected to the middle frame 101 that is not embedded in the first through hole k1.

[0131] It should be noted that the contact member can also be of any other shape. For example, the contact member can be a cube, and the first through hole is also a cube, as long as the cube contact member can achieve a good electrical connection with the middle frame.

[0132] The conductive elastic sheet provided in the embodiment of the present application contacts the middle frame through the protruding ball head connecting member, especially contacts the cylindrical structure, and the electrical connection will be more stable; and, through the grounding scheme of laser engraving on the middle frame, the broken board area only needs to be about 3.2 mm 2 or so, which can reduce the broken board area by about 70% compared with the related technology, greatly improving the stability.

[0133] Next, specific embodiments are used to describe in detail the electronic device provided by the present application. For the convenience of description, the following embodiments take the electronic device as a mobile phone, the elastomer as a conductive elastic sheet, the bracket as a shielding cover, the first component as a middle frame, and the circuit board as a PCB for detailed description.

[0134] In order to enable the middle frame to maintain electrical contact with the PCB in the internal accommodation space even after sliding out of the internal accommodation space relative to the mobile phone housing, the mobile phone can further include a conductive elastic sheet, and the conductive elastic sheet is mounted on the shielding cover.

[0135] As Figures 5 to 13As shown, the PCB has a first surface m1, a second surface m2 facing away from the first surface m1, a first through-hole k1 penetrating through the first surface m1 and the second surface m2, and three second through-holes k3 penetrating through the first surface m1 and the second surface m2.

[0136] The shielding cover 4 has a first body 411 (the first cuboid) and a second body 412 (the second cuboid) in the shape of a cuboid, and the volume of the first cuboid is larger than that of the second cuboid. The first cuboid has a first long side, a first short side, a second long side, and a second short side connected in sequence, and the second cuboid has a third long side, a third short side, a fourth long side, and a fourth short side connected in sequence, and the first long side communicates with the third long side. A fixing foot 6 is welded on the first short side, a fixing foot 6 is welded on the second short side, two spaced-apart pins 7 are welded on the second long side, and a pin 7 is welded on the fourth long side.

[0137] The conductive elastic sheet 5 includes a fixing portion 51, a first sub-bending section 521, a second sub-bending section 522, a force arm section 523, a pruning section 524, and a convex ball connected in sequence. The first sub-bending section 521 bends away from the pruning section 524 and does not contact the side of the fixing portion 51 facing away from the shielding cover 4. The second sub-bending section 522 is parallel to the side of the fixing portion 51 facing away from the shielding cover 4. The force arm section 523 inclines away from the fixing portion 51. One end of the pruning section 524 is slidable relative to the fixing portion 51, and the convex ball is arranged on the force arm section 523.

[0138] The middle frame 101 has a cylindrical structure 1011 and a middle frame base 1012.

[0139] The following will detail the processes of how the conductive elastic sheet is fixed to the shielding cover and how the elastic component is electrically connected to the middle frame.

[0140] First, two positioning holes k2 are respectively provided on the first cuboid. At the same time, two positioning holes k2 are respectively provided on the fixing portion 51. The shielding cover 4 and the fixing portion 51 are inserted on the fixture to position the shielding cover 4 and the conductive elastic sheet 5, and then spot welding positioning is performed at the connection point L1 so that the conductive elastic sheet 5 is spot welded to the shielding cover 4.

[0141] Then, the shielding cover 4 is turned over so that the fifth surface m5 faces the first surface m1 of the PCB. The two fixing feet 6 on the shielding cover 4 are spot welded on the first surface m1. The three pins 7 on the shielding cover 4 are inserted into the second through-holes k3 and soldered to the PCB through solder, thereby fixing the shielding cover 4.

[0142] Finally, forcefully insert the conductive elastic sheet 5 into the first through hole k1. At this time, the pruning section 524 slides to abut against the fixing part 51, and the convex ball is embedded in the first through hole k1. Then, insert the cylindrical structure 1011 in the middle frame 101 into the first through hole k1 to contact the convex ball, realizing electrical connection.

[0143] Figure 13 It shows how the electrical signal on the PCB flows to the middle frame 101 after the convex ball is embedded in the first through hole k1.

[0144] As Figure 13 shown, the bottom of the conductive elastic sheet 5 is welded to the shielding cover 4 by electric welding, so they are electrically connected; the other end of the shielding cover 4 is welded to the PCB, and the electrical signal D1 on the PCB can flow to the conductive elastic sheet 5 through the shielding cover 4. Thus, when the conductive elastic sheet 5 is assembled onto the PCB, the convex ball of the conductive elastic sheet 5 is connected to the middle frame 101, and a path is formed. The electrical signal D1 can flow from the pruning section 524 to the middle frame 101 or from the lever arm section 523 to the middle frame 101, thereby realizing the flow of the electrical signal D1 on the PCB to the middle frame 101.
