Description

[0001] This application is a divisional application. The application number of the original application is 202280032183.8, the original application date is April 26, 2022, and the entire content of the original application is incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technologies, and particularly to a shrapnel connection structure and an electronic device. Background Art

[0003] In order to avoid electromagnetic interference to electrical components in an electronic device such as a mobile phone, electrical components in the mobile phone such as antennas need to be electrically connected to the middle frame reference ground in the mobile phone.

[0004] Currently, antennas of electronic devices such as mobile phones are usually provided on the housing of the mobile phone. For example, a flexible printed circuit (FPC) antenna is generally located on the head and bottom of the middle frame and covers four corners of the middle frame. There is a distance between the FPC antenna and the circuit board of the mobile phone to meet the radiation requirements of the antenna on the mobile phone. In existing electronic devices such as mobile phones, the FPC antenna is usually connected to the middle frame reference ground in the mobile phone through a shrapnel, so as to realize the contact conduction between the FPC antenna and the middle frame reference ground through the shrapnel. Among them, the shrapnel is usually welded to the middle frame of the mobile phone and locked to the middle frame reference ground through fasteners such as screws.

[0005] However, welding the shrapnel to the middle frame of the mobile phone will result in a relatively high manufacturing cost of the mobile phone. Summary of the Invention

[0006] This application provides a shrapnel connection structure and an electronic device, which helps to reduce the manufacturing cost of the electronic device.

[0007] In a first aspect of an embodiment of this application, a shrapnel connection structure is provided, which is applied to an electronic device. The shrapnel connection structure includes a first connection end and a second connection end that are connected to each other. The first connection end includes a first contact portion, and the first contact portion elastically abuts and conducts with a first conductor inside the electronic device. The second connection end is detachably connected to an insulator inside the electronic device, and the second connection end abuts and conducts with a second conductor inside the electronic device.

[0008] In the embodiment of the present application, a second connection end is provided on the elastic sheet connection structure, and the second connection end is connected to the first connection end. When the first contact portion on the first connection end elastically abuts against the first conductor in the electronic device, the first connection end can abut against and conduct with the second conductor inside the electronic device through the second connection end, thereby realizing the conduction between the first conductor and the second conductor, so as to form a signal transmission path between the first conductor and the second conductor. At the same time, compared with the existing fixing method of the elastic sheet, through the setting of the second connection end in the embodiment of the present application, on the one hand, it is convenient to detachably connect the elastic sheet connection structure to the insulating part, realizing the fixation of the elastic sheet connection structure in the electronic device, which helps to reduce the manufacturing cost of the electronic device. On the other hand, the insulating part inside the electronic device can be used to fix the first connection end, so that there are more choices for the installable positions of the elastic sheet connection structure in the electronic device.

[0009] In a possible implementation manner, the second connection end is detachably connected to the insulating part and the second conductor through a fastener. In this way, while realizing the fixation of the elastic sheet connection structure in the electronic device, abutting against and conducting with the first conductor and the second conductor, there is no need to fix the elastic sheet connection structure by welding, which is convenient for the fixation of the elastic sheet connection structure in the electronic device and helps to reduce the manufacturing cost of the electronic device. At the same time, the second connection end can be tightly connected to the second conductor through the fastener, which helps to enhance the stability and reliability of the conduction between the first conductor and the second conductor.

[0010] In a possible implementation manner, a through hole for the fastener to pass through is provided on the second connection end, and the fastener passes through the through hole and the insulating part to connect the second connection end and the second conductor.

[0011] In this way, through the setting of the through hole, it is convenient for the fastener to pass through the second connection end to realize the detachable connection between the second connection end and the second conductor.

[0012] In a possible implementation manner, the second connection end covers a part of the surface of the insulating part and abuts against and conducts with the second conductor. In this way, by covering the second connection end on a part of the surface of the insulating part, it is convenient for the second connection end to abut against and conduct with the second conductor, which helps to realize the conduction between the first conductor and the second conductor.

[0013] In a possible implementation manner, the second connection end includes a substrate and a second contact portion. The second contact portion is located on the side of the substrate facing the edge of the electronic device. The second contact portion extends from the edge of the substrate and covers a part of the surface of the insulating part, and the second contact portion abuts against and conducts with the second conductor. The second connection end is clamped to the insulating part through the second contact portion.

[0014] In this way, through the setting of the second contact part, on the one hand, the second connection end can be conducted with the second conductor, so as to realize the conduction between the first conductor and the second conductor. On the other hand, it can be clamped with the insulating part, making the fixing of the elastic sheet connection structure and the insulating part more reliable, thereby further enhancing the stability and reliability of the conduction between the first conductor and the second conductor.

[0015] In a possible implementation manner, the first end of the second contact part is connected to the substrate, and the second end of the second contact part extends from the edge of the substrate to the side of the insulating part opposite to the substrate.

[0016] This can increase the contact area between the second contact part and the second conductor, making the connection between the second connection end and the second conductor more stable and reliable, so as to further enhance the stability and reliability of the conduction between the first conductor and the second conductor.

[0017] In a possible implementation manner, the second contact part includes a connecting section, and the connecting section is connected between the first end and the second end. A receiving space for receiving the insulating part is formed between the second contact part and the substrate.

[0018] In this way, through the setting of the receiving space, on the one hand, the second end part of the second contact part can cover the insulating part, so as to facilitate the clamping of the second connection end with the insulating part. On the other hand, the second end of the second contact part can be tightly connected to the second conductor through the insulating part, so as to enhance the stability and reliability of the connection between the second contact part and the second conductor.

[0019] In a possible implementation manner, the second end of the second contact part is a plate-like structure parallel to the substrate. Through the setting of this plate-like structure, not only can the contact area between the second end of the second contact part and the second conductor be increased, but also the insulating part can be kept on the same level, so that the first contact part is always in contact with and conducts with the first conductor.

[0020] In a possible implementation manner, the second contact part includes a plugging section plugged into the insulating part. The plugging section extends from the edge of the second end, and the plugging section is plugged on the insulating part.

[0021] In this way, through the setting of the plugging section, the fixing effect of the second connection end on the insulating part can be strengthened, so as to realize the stable connection between the elastic sheet connection structure and the insulating part, thereby further enhancing the stability and reliability of the conduction between the first conductor and the second conductor.

[0022] In a possible implementation manner, a clamping part is further provided at the edge of the substrate, and the clamping part is clamped with the edge of the insulating part. In this way, through the setting of the clamping part, on the one hand, the relative movement between the insulating part and the second connection end can be further avoided. While facilitating the further connection and fixing with the insulating part, the stability and reliability of the conduction between the first conductor and the second conductor can be ensured.

[0023] In a possible implementation, at least two engaging portions are further provided at the edge of the substrate, and the engaging portions are located on the peripheral side of the substrate. In this way, the movement of the second connection end relative to the insulating member can be further limited by the engaging portions, so as to avoid relative movement of the second connection end relative to the insulating member.

[0024] In a possible implementation, the engaging portions are distributed on both sides of the second contact portion. In this way, while ensuring the engagement between the engaging portion and the insulating member, it is convenient to arrange the elastic sheet connection structure on the insulating member.

[0025] In a possible implementation, the engaging portion is a folded edge bent toward the insulating member on the edge of the substrate. In this way, through the arrangement of the folded edge, it is convenient to realize the engagement between the second connection end and the insulating member.

[0026] In a possible implementation, the elastic sheet connection structure further includes a connecting portion, and the first connection end is connected to the second connection end through the connecting portion. In this way, through the arrangement of the connecting portion, the position of the first contact portion on the elastic sheet connection structure can be adjusted, so that the position freedom degree of the first contact portion on the elastic sheet connection structure is higher.

[0027] In a possible implementation, the first contact portion is an elastic arm or an elastic protrusion. In this way, while ensuring the abutment and conduction between the first contact portion and the first conductor, the structure of the first contact portion can be made more diversified.

[0028] In a possible implementation, two oppositely arranged limiting portions are further provided on the first connection end, and the first contact portion is located between the two limiting portions. In this way, the first contact portion can be limited by the limiting portions, so as to avoid excessive position deviation when the first contact portion moves relative to the first connection end under the action of an external force.

[0029] In the second aspect of the embodiments of the present application, an electronic device is provided, which includes a housing, a first conductor and a second conductor. An insulating member and the above-mentioned elastic sheet connection structure are provided in the housing. The elastic sheet connection structure is detachably connected to the second conductor through the insulating member. At least one of the first conductor and the second conductor is provided on the housing, and the first conductor is in abutment and conduction with the second conductor through the elastic sheet connection structure.

[0030] In the embodiments of the present application, the elastic sheet connection structure is detachably connected to the second conductor through the insulating member. In this way, while the elastic sheet connection structure realizes the conduction between the first conductor and the second conductor to improve the electromagnetic interference resistance ability of the electronic device, the insulating member can be used as a fixing structure of the elastic sheet connection structure to fix the elastic sheet connection structure inside the electronic device, without welding the elastic sheet connection structure to the housing. This not only facilitates the fixing of the elastic sheet connection structure and reduces the manufacturing cost of the electronic device, but also enables more selectivity in the installable positions of the elastic sheet connection structure inside the electronic device.

[0031] In a possible implementation, an assembly groove is provided on the insulating member, and the elastic sheet connection structure is arranged in the assembly groove. Through the provision of the assembly groove, while realizing the assembly of the elastic sheet connection structure, not only does the position freedom of the first contact portion on the elastic sheet connection structure become higher, but also it does not affect the overall thickness of the electronic device.

[0032] In a possible implementation, the first conductor is one of a flexible circuit board antenna and a backlight bracket of a display screen, and / or the second conductor is a reference ground on a middle frame of a housing.

[0033] In this way, the flexible circuit board antenna or the backlight bracket can be abutted against and conduct with the reference ground through the elastic sheet connection structure, thereby forming a signal transmission path between the flexible circuit board antenna or the backlight bracket and the reference ground.

[0034] In a possible implementation, the insulating member is a speaker box in the housing or an insulating bracket in the housing. In this way, the speaker box or the insulating bracket can be used to fix the elastic sheet connection structure, which helps to further reduce the manufacturing cost of the electronic device.

[0054] Currently, in electronic devices such as mobile phones, it is usually necessary to conduct the antennas and other components inside the mobile phone to the middle frame reference ground inside the mobile phone, so that the middle frame reference ground becomes the zero potential point of the antennas and other components, and a signal transmission path is formed between the antenna and the middle frame reference ground to avoid the influence of the middle frame reference ground on the performance of the antenna and improve the electromagnetic interference resistance of the mobile phone. Among them, the middle frame reference ground can be understood as the metal support plate in the middle area of the middle frame inside the mobile phone.

[0055] The antennas in existing electronic devices such as mobile phones are usually installed on the housing of the mobile phone. Taking the FPC antenna as an example, the FPC antenna is usually installed on the head and bottom of the middle frame of the housing and covers the four corners of the middle frame. In order to connect and conduct the FPC antenna to the middle frame reference ground inside the mobile phone, a shrapnel is usually arranged between the FPC antenna and the middle frame reference ground inside the mobile phone. Since the shrapnel is usually made of conductive materials such as metal, when one end of the shrapnel abuts against the FPC antenna and the other end abuts against the middle frame reference ground, the FPC antenna can be connected and conducted to the middle frame reference ground.

[0056] In order to fix the shrapnel inside the mobile phone, the common existing method is to fix the shrapnel to the middle frame of the mobile phone by welding. Then through holes are opened in the shrapnel, the middle frame, and the middle frame reference ground, and screws and the like are passed through the through holes to connect the shrapnel, the middle frame, and the reference ground, so as to lock the shrapnel to the middle frame reference ground by screws. In this way, while the shrapnel is fixed, the FPC antenna can be stably connected and conducted to the middle frame reference ground.

[0057] However, in order to ensure the effectiveness and reliability of the connection between the FPC antenna and the middle frame reference ground, there are relatively high requirements for the welding process and the welding effect. Due to the limitations of the welding process and the welding effect, the cost of welding the shrapnel to the middle frame is relatively high, which will result in a relatively high manufacturing cost of the mobile phone. In addition, due to the continuous development of electronic devices towards high screen-to-body ratio and thinness and lightness, the structure of the middle frame is continuously compressed, and the space on the middle frame where the shrapnel can be welded and holes can be opened is relatively limited. To a certain extent, this restricts the installation of the shrapnel on the middle frame and limits the degree of freedom of the installable position of the shrapnel on the middle frame.

[0058] In view of this, an embodiment of the present application provides a shrapnel connection structure and an electronic device. By providing a second connection end on the shrapnel connection structure and connecting and conducting the second connection end to the first connection end of the shrapnel connection structure, when the first contact portion on the first connection end abuts against the first conductor in the electronic device, the first connection end can abut against and conduct with the second conductor inside the electronic device through the second connection end, thereby realizing the conduction between the first conductor and the second conductor. At the same time, compared with the existing fixed method of welding shrapnel, through the setting of the second connection end in the embodiment of the present application, not only can the detachable connection between the shrapnel connection structure and the insulating member be facilitated, the fixation of the shrapnel connection structure in the electronic device be realized, which helps to reduce the manufacturing cost of the electronic device, but also the insulating member inside the electronic device can be used to fix the second connection end and the shrapnel connection structure, so that the selectivity of the installable positions of the shrapnel connection structure in the electronic device is more, in order to realize the reliable grounding of the first conductors of different structures in the electronic device.

[0059] Among them, in this embodiment, the electronic device may include, but is not limited to, any device with grounding and electrical connection requirements such as mobile phones, tablet computers, laptop computers, ultra-mobile personal computers (UMPCs), handheld computers, walkie-talkies, netbooks, POS machines, personal digital assistants (PDAs), wearable devices (such as watches or bracelets), virtual reality devices, televisions, etc.

[0060] Next, taking a mobile phone as an example, the electronic device in the embodiment of the present application will be described.

[0061] Embodiment

[0062] Figure 1a is a schematic structural diagram of the bottom wall end of a mobile phone provided by an embodiment of the present application. Figure 1b is a schematic structural diagram of the bottom wall end of a mobile phone provided by an embodiment of the present application. Figure 2 is Figure 1a a schematic structural diagram of part A of the mobile phone in Figure 3 after being jointly cut in the B-B direction and the D-D direction. Figure 2 is an enlarged schematic diagram of part E of the mobile phone in Figure 4 is Figure 1a a schematic structural diagram of part A of the mobile phone in Figure 5 after being jointly cut in the C-C direction and the D-D direction. Figure 4 is an enlarged schematic diagram of part F of the mobile phone in Figure 1b From another perspective, it reflects Figure 1aDifferent cutting directions in order to better understand Figure 1a the different cutting positions in

[0063] Figures 2 to 5 In Figure 1a Based on this, schematic diagrams of the structures after cutting at different positions along the length direction of the mobile phone are respectively provided. As can be seen from Figure 2 and Figure 3 An electronic device such as a mobile phone 100 may include a housing 10, a first conductor 13, and a second conductor 14. An insulating member 20 and the elastic sheet connection structure 30 as described above are provided inside the housing 10. At least one of the first conductor 13 and the second conductor 14 is provided on the housing 10. The elastic sheet connection structure 30 is detachably connected to the second conductor 14 through the insulating member 20, and the first conductor 13 abuts against and conducts with the second conductor 14 through the elastic sheet connection structure 30. In this way, through the elastic sheet connection structure 30, it can be ensured that the first conductor 13 conducts with the second conductor 14, and a signal transmission path is formed between the first conductor 13 and the second conductor 14 to improve the electromagnetic interference resistance of the electronic device.

[0064] At the same time, since the elastic sheet connection structure 30 can be detachably connected to the second conductor 14 through the insulating member 20, the insulating member 20 can be used as a fixing structure for the elastic sheet connection structure 30 to fix the elastic sheet connection structure 30 inside an electronic device such as a mobile phone 100. In the embodiment of the present application, it is not necessary to weld the elastic sheet connection structure 30 to the housing 10. Compared with the method of welding the elastic sheet to the middle frame 11, not only can the fixing method of the elastic sheet connection structure 30 be simplified, the fixing cost of the elastic sheet connection structure 30 be reduced, and thus the manufacturing cost of the electronic device be reduced, but also the selectivity of the installable positions of the elastic sheet connection structure 30 inside the electronic device can be increased.

[0065] It should be noted that the above-mentioned detachable connection can be understood as that the elastic sheet connection structure 30 can be disconnected after being connected to the second conductor 14 through the insulating member 20, which facilitates the disassembly of the elastic sheet connection structure 30. Exemplarily, the elastic sheet connection structure 30 can be connected to at least one of the insulating member 20 and the second conductor 14 by means of a fastener connection or a snap connection.

[0066] For the convenience of installing the elastic sheet connection structure 30, as Figure 2 and Figure 3As shown in the figure, an assembly groove 21 is provided on the insulating member 20, and the elastic sheet connection structure 30 is arranged in the assembly groove 21. By providing the assembly groove 21 on the insulating member 20, on the one hand, the assembly of the elastic sheet connection structure 30 on the insulating member 20 can be realized, so as to be detachably connected with the second conductor 14 through the insulating member 20; on the other hand, the elastic sheet connection structure 30 can be embedded in the assembly groove 21 to avoid affecting the overall thickness of the electronic device due to the arrangement of the elastic sheet connection structure 30 on the insulating member 20.

[0067] Among them, referring to Figure 2 and Figure 3 As shown, the assembly groove 21 can be arranged at the corner of the insulating member 20. In this way, while facilitating the connection between the elastic sheet connection structure 30 and the insulating member 20 and abutting and conducting with the second conductor 14, it can avoid adversely affecting the arrangement of the speaker in the speaker box due to the arrangement of the assembly groove 21.

[0068] Among them, when the insulating member 20 is a non-circular structure, such as a square structure, the corner can be understood as the positions where the 4 corners of the square structure are located.

[0069] Referring to Figures 2 to 3 As shown, the insulating member 20 can be the speaker box in the mobile phone 100 or other insulating housings. In this way, while using the existing structure in the mobile phone 100 to fix the elastic sheet connection structure 30, on the one hand, there is no need to additionally provide a fixing structure for the elastic sheet connection structure 30, such as an adapter circuit board, in the electronic device, which helps to further reduce the manufacturing cost of the electronic device; on the other hand, since the elastic sheet connection structure 30 is assembled in the assembly groove 21 at the corner of the speaker box, therefore, while ensuring the normal use of the speaker, it will not affect the spatial layout in the electronic device.

[0070] It can be understood that the speaker box is an insulating housing prepared from an insulating material such as plastic. It should be noted that, as Figure 4 and Figure 5 As shown, the assembly groove 21 can be jointly formed by an assembly table 23 at the corner of the speaker box and the outer side wall 24 of the speaker box. That is to say, the assembly groove 21 can be formed on the outer surface of the speaker box.

[0071] Alternatively, in this embodiment, the insulating member 20 can also be an insulating bracket in the housing 10, and the assembly groove 21 can be formed at the corner of the insulating bracket. That is to say, the insulating member 20 includes but is not limited to the speaker box in the mobile phone 100. In this embodiment, the structure of the insulating member 20 is not further limited.

[0072] It should be noted that the assembly groove 21 can correspond to the first conductor 13 and the second conductor 14. In this way, when the elastic sheet connection structure 30 is arranged in the assembly groove 21, it is convenient to conduct the first conductor 13 and the second conductor 14 through the elastic sheet connection structure 30.

[0073] Specifically, the first conductor 13 can be a structural metal bracket in the mobile phone 100, such as a backlight bracket of a display screen, Figure 4 and Figure 5 the flexible circuit board antenna shown in, flexible boards of various types of sensors, or other conductor structures that need to be grounded in the electronic device. That is to say, the first conductor 13 includes but is not limited to the flexible circuit board antenna or the backlight bracket of the display screen. In this embodiment, the first conductor 13 can be one of the flexible circuit board antenna and the backlight bracket of the display screen. In this way, the flexible circuit board antenna or the backlight bracket can be grounded through the elastic sheet connection structure 30 to improve the electromagnetic interference resistance of the electronic device.

[0074] Correspondingly, the second conductor 14 can be, for example, Figure 4 and Figure 5 the reference ground on the middle frame 11 of the housing 10 shown in. Or, the second conductor 14 can also be a metal plate in the electronic device such as the mobile phone 100 that can be used as the zero potential point of the first conductor 13. That is to say, in this embodiment, the second conductor 14 includes but is not limited to the reference ground on the middle frame 11. In this way, the flexible circuit board antenna or the backlight bracket can be conducted with the reference ground on the middle frame 11 through the elastic sheet connection structure 30, so as to form a signal transmission path between the flexible circuit board antenna or the backlight bracket and the reference ground.

[0075] The reference ground can be understood as a metal support plate in the middle area of the middle frame 11. Among them, the metal support plate can be a support plate made of alloy materials such as aluminum alloy, magnesium alloy, or other metal materials.

[0076] Among them, the middle frame 11 can include a frame 111 and a metal support plate. The frame 111 surrounds the periphery of the metal support plate and is connected to the edge of the metal support plate. The housing 10 of the electronic device can also include a battery, a circuit board, etc. The battery, the circuit board, etc. are all fixed on the metal support plate.

[0077] It should be noted that when the first conductor 13 is different structures in the electronic device, since the elastic sheet connection structure 30 needs to conduct the first conductor 13 and the second conductor 14 and ground them, therefore, the elastic sheet connection structure 30 can also be located at different positions of the electronic device.

[0078] Specifically, referring to Figure 4 and Figure 5As shown, the housing 10 further includes a fixing member 12, which is located above the first conductor 13 and is used to fix the first conductor 13. The edge of the fixing member 12 located inside the housing 10 extends towards the direction of the elastic sheet connection structure 30 and the insulating member 20 to the assembly groove 21. The elastic sheet connection structure 30 can also be detachably connected to the fixing member 12 through a fastener 40 as shown in Figure 2 and Figure 3 . In this way, under the combined action of the fastener 40 and the fixing member 12, the elastic sheet connection structure 30 can be closely attached to the first conductor 13, the insulating member 20, and the second conductor 14 respectively, which helps to enhance the stability and reliability of the conduction between the first conductor 13 and the second conductor 14.

[0079] Furthermore, in order to avoid the fastener 40 affecting the thickness of the electronic device, as shown in Figure 2 and Figure 3 , a groove 121 can be provided on the fixing member 12. The fastener 40 is embedded in the groove 121 and passes through the groove 121 to detachably connect the elastic sheet connection structure 30 to the insulating member 20 and the second conductor 14. In this way, while realizing the detachable connection between the fixing member 12 and the fixing member 12, it can avoid the influence of the setting of the fastener 40 on the thickness of the electronic device.

[0080] Among them, the fastener 40 includes but is not limited to screws, bolts or other connectable structures.

[0081] Exemplarily, the fixing member 12 can be an insulating decorative member on the housing 10, such as a plastic decorative member, or the fixing member 12 can also be an insulating fixing structure made of other insulating materials. That is to say, the fixing member 12 includes but is not limited to insulating decorative members.

[0082] When the fixing member 12 is an insulating decorative member, since part of the insulating decorative member is provided on the frame 111 of the middle frame 11 and is attached to the flexible circuit board antenna, the insulating decorative member has a better fixing effect on the flexible circuit board antenna. At the same time, in order to facilitate the detachable connection between the fixing member 12 and the elastic sheet connection structure 30, the edge of the fixing member 12 located inside the housing 10 can also extend towards the middle of the housing 10 to above the elastic sheet connection structure 30.

[0083] Specifically, the housing 10 can further include a rear cover. The rear cover, the insulating decorative member, and the middle frame 11 can form the housing 10 of an electronic device such as a mobile phone 100. The elastic sheet connection structure 30 can be located between the middle frame 11 and the rear cover. In this embodiment, the rear cover can be a metal rear cover, a glass rear cover, a plastic rear cover, or a ceramic rear cover. In the embodiments of the present application, the material of the rear cover is not limited.

[0084] An electronic device such as a mobile phone 100 may further include a display screen, and the display screen and the back cover may be disposed on opposite sides of the middle frame 11. The display screen can be used to display information input by the user or information provided to the user, as well as various menus of the electronic device, and can also accept user input. In this embodiment, the display screen can be a flat screen or a curved screen.

[0085] It can be understood that the structure illustrated in the embodiments of the present application does not constitute a specific limitation on the mobile phone 100. In other embodiments of the present application, the mobile phone 100 may include more or fewer components than those illustrated, or combine certain components, or split certain components, or have different component arrangements. The illustrated components can be implemented in hardware, software, or a combination of software and hardware.

[0086] To reduce the manufacturing cost of the electronic device, an elastic sheet connection structure 30 is provided in the embodiments of the present application. The elastic sheet connection structure 30 is applied to an electronic device such as a mobile phone 100 to replace the elastic sheet in the existing mobile phone 100. Taking the mobile phone 100 as an example, in the application scenario where the first conductor 13 is a flexible circuit board antenna and the second conductor 14 is the reference ground on the middle frame 11, in combination with Figures 2 to 12 a specific description of the elastic sheet connection structure 30 provided in the embodiments of the present application is given.

[0087] Figure 6 For the Figure 1a structural schematic diagram of the mobile phone after removing the middle frame in the embodiments of the present application, Figure 7 For Figure 6 the enlarged schematic diagram of part G of the mobile phone in Figure 8 For Figure 7 the structural schematic diagram of the mobile phone after removing the FPC antenna in

[0088] Figures 2 to 8 For the assembly schematic diagram of the elastic sheet connection structure 30 in the mobile phone 100. The elastic sheet connection structure 30 is applied to an electronic device. It can be seen from Figure 8 that the elastic sheet connection structure 30 includes a first connection end 31 and a second connection end 32 that are connected and conductively connected to each other. The first connection end 31 includes a first contact portion 311, and the first contact portion 311 elastically abuts and conducts with the first conductor 13 inside the electronic device. The second connection end 32 is detachably connected to the insulating member 20 inside the electronic device, and the second connection end 32 abuts and conducts with the second conductor 14 inside the electronic device. Thus, through the setting of the second connection end 32 on the elastic sheet connection structure 30, in combination with Figures 6 to 8It can be known that when the first contact portion 311 abuts against the first conductor 13, the first connection end 31 can abut against and conduct with the second conductor 14 inside the electronic device through the second connection end 32. At this time, the elastic sheet connection structure 30 can be regarded as the connection structure between the first conductor 13 and the second conductor 14, so that the first conductor 13 and the second conductor 14 are conducted, so as to form a signal transmission path between the first conductor 13 and the second conductor 14, so as to avoid the influence of the second conductor 14 on the performance of the first conductor 13, and help improve the electromagnetic interference resistance of the electronic device.

[0089] At the same time, compared with the existing fixed method of elastic sheet welding, through the setting of the second connection end 32 in the embodiment of the present application, on the basis of ensuring that the first contact portion 311 abuts against and conducts with the first conductor 13, on the one hand, it can make the elastic sheet connection structure 30 detachably connected to the insulating member 20 through the second connection end 32, which is convenient for the connection between the elastic sheet connection structure 30 and the insulating member 20. While realizing the fixation of the elastic sheet connection structure 30 in the electronic device, the fixation method of the elastic sheet connection structure 30 can be simplified, so as to reduce the manufacturing cost of the electronic device by reducing the fixation cost of the elastic sheet connection structure 30; on the other hand, it can utilize the insulating member 20 inside the electronic device to fix the first connection end 31. The insulating member 20 can be used as the transfer and fixation structure of the second connection end 32 and the elastic sheet connection structure 30, and there is no need to weld the first connection end 31 and the elastic sheet connection structure 30 to the housing 10, so that the elastic sheet connection structure 30 has more options for the installable positions in the electronic device.

[0090] It should be noted that the elastic sheet connection structure 30 can be located between the first conductor 13 and the insulating member 20, so that when the elastic sheet connection structure 30 is detachably connected to the insulating member 20 through the second connection end 32, the elastic sheet connection structure 30 can abut against and conduct with the first conductor 13 through the first contact portion 311.

[0091] Among them, the first conductor 13 can be a flexible printed circuit antenna, i.e., an FPC antenna, as shown in Figure 6 and Figure 7 The second conductor 14 is the reference ground on the middle frame 11, and the insulating member 20 is the speaker box. By arranging the elastic sheet connection structure 30 on the speaker box in this way, the FPC antenna can be connected and conducted with the reference ground on the middle frame 11, so as to realize the grounding of the FPC antenna.

[0092] Specifically, as shown in Figure 8As shown, the fixed seat 32 is detachably connected to the insulating member 20 and the second conductor 14 through the fastener 40. In this way, while the elastic sheet connection structure 30 is arranged in the assembly groove 21, the elastic sheet connection structure 30 can be fixed to the insulating member 20 through the fastener 40, and while being in contact with and conducting electricity with the first conductor 13 and the second conductor 14, there is no need to fix the elastic sheet connection structure 30 by welding, which can simplify the fixing of the elastic sheet connection structure 30 in the electronic device and help reduce the manufacturing cost of the electronic device.

[0093] In addition, the elastic sheet connection structure 30 can be locked to the insulating member 20 and the second conductor 14 through the fastener 40, so that the second connection end 32 is tightly connected to the second conductor 14, which helps to enhance the stability and reliability of the conduction between the first conductor 13 and the second conductor 14, achieving the purpose of stable grounding of the first conductor 13 such as an FPC antenna.

[0094] For the convenience of the connection of the fastener 40, as shown in Figure 8 Each of the second connection ends 32 is provided with a through hole 324 for the fastener 40 to pass through. The fastener 40 passes through the through hole 324 and the insulating member 20 to connect the second connection end 32 and the second conductor 14. In this way, through the setting of the through hole 324, it is convenient for the fastener 40 to pass through the second connection end 32 to be connected to the second conductor 14, so that the second connection end 32, the insulating member 20 and the second conductor 14 are detachably connected through the fastener 40.

[0095] Among them, the through hole 324 can be a threaded hole or other holes through which the fastener 40 can pass, and the through hole 324 can connect the second connection end 32 to the insulating member 20 and the second conductor 14. That is to say, the through hole 324 includes but is not limited to a screw hole adapted to the fastener 40.

[0096] For the convenience of the fastener 40 passing through the insulating member 20, the insulating member 20 is also provided with the above-mentioned through hole 324 for the fastener 40 to pass through at a position opposite to the through hole 324.

[0097] It should be understood that the second conductor 14 is also provided with a connection hole (not marked in the figure) at a position opposite to the through hole 324. In this way, after the fastener 40 passes through the through hole 324 of the insulating member 20, it can be connected to the second conductor 14 at the connection hole. Among them, the connection hole can be a threaded through hole 324 or a threaded blind hole. In this embodiment, the structure of the connection hole is not further limited.

[0098] It should be noted that when the fixing member 12 extends to the assembly groove 21, as shown in Figure 2 and Figure 3As shown in the figure, the same fastener 40 can also penetrate through the groove 121 of the fixing member 12, and connect the fixing member 12 to the second connection end 32, the insulating member 20, and the second conductor 14, so as to fix the fixing member 12 on the second connection end 32. In this way, under the combined action of the pressing of the fixing member 12 and the locking of the fastener 40, the abutting degree between the first contact portion 311 and the first conductor 13, and between the second connection end 32 and the second conductor 14 can be enhanced, thereby enhancing the stability and reliability of the conduction between the first conductor 13 and the second conductor 14, and enabling the stable grounding of the first conductor 13.

[0099] The fixing member 12 is also provided with screw holes, threaded holes or other holes that can connect the fastener 40 in the groove 121. This can facilitate the fastener 40 to pass through the fixing member 12 and connect with the elastic sheet connection structure 30, the insulating member 20, and the second conductor 14.

[0100] To facilitate the understanding of the connection between the elastic sheet connection structure 30 and the insulating member 20, in the embodiment of the present application, Figure 7 the first conductor 13 such as the FPC antenna in the figure is hidden, forming a structure as shown in Figure 8 the figure. It can be seen from Figure 8 the figure that the second connection end 32 covers a part of the surface of the insulating member 20, and abuts and conducts with the second conductor 14. This can facilitate the abutting and conduction between the second connection end 32 and the second conductor 14, so that the first conductor 13 can conduct with the second conductor 14 through the elastic sheet connection structure 30, thereby grounding the first conductor 13 and improving the electromagnetic interference resistance of electronic devices such as the mobile phone 100.

[0101] Specifically, as shown in Figure 8 the figure, the second connection end 32 may include a substrate 321 and a second contact portion 322. The second contact portion 322 is located on the side of the substrate 321 facing the edge of the electronic device. The second contact portion 322 extends from the edge of the substrate 321 and covers a part of the surface of the insulating member 20, and the second contact portion 322 abuts and conducts with the second conductor 14. In this way, the second connection end 32 can be conducted with the second conductor 14 through the second contact portion 322, thereby realizing the conduction between the first conductor 13 and the second conductor 14. At the same time, the second connection end 32 is clamped with the insulating member 20 through the second contact portion 322. In this way, through clamping, the position of the second connection end 32 on the insulating member 20 can be pre-fixed to avoid the position deviation of the second connection end 32 when it is further fixed on the insulating member 20, so as to facilitate the further connection between the second connection end 32 and the insulating member 20, such as connection through the fastener 40. In addition, the second connection end 32 is clamped with the insulating member 20 through the second contact portion 322, which can also make the fixation between the elastic sheet connection structure 30 and the insulating member 20 more reliable, contributing to further enhancing the stability and reliability of the conduction between the first conductor 13 and the second conductor 14.

[0102] Reference Figure 8 As shown, the first end 3221 of the second contact portion 322 is connected to the substrate 321, and the second end 3222 of the second contact portion 322 extends from the edge of the substrate 321 to the side of the insulating member 20 opposite to the substrate 321. In this way, the second end 3222 of the second contact portion 322 can be located between the insulating member 20 and the second conductor 14 and abut against one side of the second conductor 14 facing the insulating member 20, so that the second connection end 32 and the second conductor 14 abut against each other through two opposite surfaces, increasing the abutting area between the second contact portion 322 and the second conductor 14, making the connection between the second connection end 32 and the second conductor 14 more stable and reliable, enabling the first conductor 13 and the second conductor 14 to conduct with high stability and reliability, and thus achieving the purpose of reliably grounding the first conductor 13 such as an FPC antenna.

[0104] Among them, reference Figures 9 to 12 As shown, the second contact portion 322 includes a connecting section 3224, and the connecting section 3224 is connected between the first end 3221 and the second end 3222. A receiving space 326 for receiving the insulating member 20 is formed between the second contact portion 322 and the substrate 321. In this way, through the setting of the receiving space 326 in the second connection end 32, the second connection end 32 can form a double-layer structure as shown in Figure 11 and Figure 12 in the Y direction, so as to place the insulating member 20 in the receiving space 326, making the second end 3222 formed and located between the insulating member 20 and the second conductor 14. While increasing the abutting area between the second connection end 32 and the second conductor 14, it can also tightly connect the second end 3222 of the second contact portion 322 and the second conductor 14 under the action of the gravity of the insulating member 20, further enhancing the stability and reliability of the conduction between the second contact portion 322 and the second conductor 14.

[0105] In addition, through the provision of the content setting space 326 of the second connection end 32 and the second contact portion 322, the second end 3222 of the second contact portion 322 can also cover the insulating member 20, realizing the snap connection between the second connection end 32 and the insulating member 20, making the positions of the second connection end 32 and the insulating member 20 relatively fixed, so as to facilitate the further connection between the second connection end 32 and the insulating member 20.

[0106] It should be noted that through the provision of the connecting section 3224, a gap can be formed between the second end 3222 and the substrate 321, so as to form a content setting space 326 between the second contact portion 322 and the substrate 321.

[0107] Exemplarily, as Figure 11 and Figure 12 shown in, the second end 3222 of the second contact portion 322 is a plate-like structure parallel to the substrate 321. Through the provision of such a plate-like structure, on the one hand, the abutting area between the second end 3222 of the second contact portion 322 and the second conductor 14 can be increased, so that the second connection end 32 is in close contact with and conducts electricity with the second conductor 14 through the second contact portion 322, which helps to improve the stability and reliability of the conduction between the first conductor 13 and the second conductor 14; on the other hand, the stability of the insulating member 20 in the content setting space 326 can also be improved, so that the insulating member 20 can be kept on the same level, so as to avoid the position deviation of the insulating member 20 in the Y direction under the action of the fastener 40 during the locking process of the fastener 40, resulting in the possible disengagement of the first contact portion 311 from the first conductor 13, affecting the abutting of the first contact portion 311 and the first conductor 13, thereby ensuring the effectiveness and reliability of the conduction between the first conductor 13 and the second conductor 14.

[0108] It should be understood that the above-mentioned through hole 324 through which the fastener 40 can pass is provided on the second end 3222 of the second contact portion 322, so that the fastener 40 can pass through the second end 3222 of the second contact portion 322 to tightly connect the second connection end 32 with the insulating member 20 and the second conductor 14.

[0109] As an alternative implementation manner, as Figure 11 and Figure 12 shown in, the second contact portion 322 includes an insertion section 3223 inserted into the insulating member 20. The insertion section 3223 is arranged close to the edge of the electronic device, extends from the edge of the second end 3222, and the insertion section 3223 is inserted and on the surface of the insulating member 20 (such as Figure 9 and Figure 10As shown in [figure reference], it is on [specific component]. In this way, on the basis of the snap connection between the second connection end 32 and the insulating part 20 and the connection of the fastener 40, inserting the insertion section 3223 into the insulating part 20 can strengthen the fixing effect of the second connection end 32 on the insulating part 20, so as to further prevent the relative movement between the second connection end 32 and the insulating part 20, in order to achieve the stable connection between the elastic sheet connection structure 30 and the insulating part 20, which helps to further enhance the stability and reliability of the conduction between the first conductor 13 and the second conductor 14, and achieve the purpose of reliable grounding of the first conductor 13, such as a PC antenna.

[0110] To facilitate the insertion of the insertion section 3223 into the insulating part 20, an insertion hole (not marked in the figure) can be provided on the assembly table 23 of the insulating part 20. The insertion hole can be exposed on the surface of the assembly table 23. The insertion section 3223 can be inserted into the insulating part 20 through the insertion hole and exposed on the surface of the insulating part 20.

[0111] It should be understood that the second end 3222 of the second contact part 322 is located on the side of the insulating part 20 opposite to the substrate 321, that is to say, the second end 3222 is located on the surface of the insulating part 20 facing the substrate 321. In order to insert the insertion section 3223 into the assembly table 23, the insertion section 3223 should be a folded edge on the side of the second end 3222 of the second contact part 322 facing the substrate 321. In this way, when inserting the insertion section 3223 into the insulating part 20, it will not affect the contact and conduction between the second contact part 322 and the second conductor 14.

[0112] As a possible implementation, as Figure 11 and Figure 12 shown in [figure reference], the second end 3222 of the second contact part 322 can partially extend along the edge of the substrate 321 to the side of the insulating part 20 opposite to the substrate 321. In this way, by adjusting and changing the extension direction of the second end 3222 multiple times, while forming the above-mentioned through hole 324 in the second end 3222, an insertion section 3223 is formed at the end of the second end 3222.

[0113] Alternatively, as another possible implementation, wherein, the second end 3222 of the second contact part 322 can also extend entirely along the edge of the substrate 321 to the side of the insulating part 20 opposite to the substrate 321. Then, the above-mentioned through hole 324 is opened in the second end 3222, and the insertion section 3223 is formed by means of mechanical processing, etc. In this embodiment, the extension method of the second end 3222 of the second contact part 322, as well as the formation methods of the through hole 324 and the insertion section 3223 are not further limited.

[0114] To further enhance the snap connection effect between the second connection end 32 and the insulating part 20, refer to Figure 11 and Figure 12As shown, a engaging portion 323 is further provided at the edge of the substrate 321, and the engaging portion 323 engages with the edge of the insulating member 20 (as shown in Figure 9 and Figure 10 shown). Thus, under the combined action of the second contact portion 322 and the engaging portion 323, the movement of the second connection end 32 relative to the insulating member 20 can be restricted, so as to avoid relative movement of the second connection end 32 when it is further connected to the insulating member 20, enhance the clamping effect between the second connection end 32 and the insulating member 20, facilitate the further connection and fixation of the second connection end 32 to the insulating member 20, and at the same time ensure the stability and reliability of the conduction between the first conductor 13 and the second conductor 14, so as to achieve the purpose of stable grounding of the first conductor 13 such as an FPC antenna.

[0115] Wherein, at least two engaging portions 323 are further provided at the edge of the substrate 321, and the engaging portions 323 are located on the peripheral side of the substrate 321. In this way, the movement of the second connection end 32 relative to the insulating member 20 can be limited by the engaging portions 323, so as to avoid relative movement of the second connection end 32 relative to the insulating member 20 during the connection process by the fastener 40. While facilitating the further connection of the second connection end 32 to the insulating member 20 by the fastener 40, the stability and reliability of the conduction between the first conductor 13 and the second conductor 14 can be ensured.

[0116] As a possible implementation manner, the engaging portions 323 can be distributed on both sides of the second contact portion 322. In this way, while ensuring the engagement between the engaging portion 323 and the insulating member 20, it is convenient to arrange the elastic sheet connection structure 30 on the insulating member 20.

[0117] Alternatively, the engaging portions 323 can be distributed on the side of the substrate 321 opposite to the second contact portion 322. In this embodiment, the setting position of the engaging portions 323 on the substrate 321 is not further limited.

[0118] Exemplarily, the engaging portion 323 can be a folded edge on the edge of the substrate 321 that is bent towards the insulating member 20. In this way, not only can the engagement between the second connection end 32 and the insulating member 20 be facilitated, but also the structures of the second connection end 32 and the elastic sheet connection structure 30 can be simplified, which helps to further reduce the manufacturing cost of the electronic device.

[0119] Further, as shown in Figure 11 and Figure 12As shown in the figure, limit bumps 325 are provided on both the substrate 321 and the second end 3222 of the second contact portion 322 facing the second conductor 14. Correspondingly, a recessed portion (not marked in the figure) adapted to the limit bumps 325 is provided on the insulating member 20. When the second connection end 32 is assembled on the insulating member 20, the limit bumps 325 are located within the recessed portion, which can further enhance the connection stability between the second connection end 32 and the insulating member 20 and the second conductor 14, and at the same time can prevent the second connection end 32 from moving relative to the insulating member 20.

[0120] As a possible implementation manner, referring to Figure 11 and Figure 12 shown, the elastic sheet connection structure 30 may further include a connection portion 33, and the first connection end 31 is connected to the second connection end 32 through the connection portion 33. In this way, by adjusting the length and structure of the connection portion 33, or adding a connection portion 33 between the first connection end 31 and the second connection end 32, the position of the first contact portion 311 on the elastic sheet connection structure 30 can be adjusted as shown in Figure 9 and Figure 10 so that the degree of freedom of the position where the first contact portion 311 can be set on the elastic sheet connection structure 30 is higher, so that the first contact portion 311 can abut and conduct with the first conductor 13 at different positions in the electronic device such as the mobile phone 100, so that the elastic sheet connection structure 30 can be applied in more scenarios in the electronic device and has a wider applicability.

[0121] Among them, the connection portion 33 may be a connection arm. Exemplarily, the connection arm may be a connection plate or a connection rod. One end of the connection arm may be connected to the connection seat 312 of the first connection end 31, and the other end may be connected to the substrate 321 of the second connection end 32, so as to simplify the structure of the elastic sheet connection structure 30 while ensuring the connection between the first connection end 31 and the second connection end 32.

[0122] In order to facilitate the fixation of the elastic sheet connection structure 30 in the assembly groove 21, as a possible implementation manner, the insulating member 20 may further be provided with a card slot 22 in the assembly groove 21. When the elastic sheet connection structure 30 is provided in the assembly groove 21, as shown in Figure 9 the elastic sheet connection structure 30 can be engaged with the card slot 22 through the engaging block 331 on the connection portion 33. In this way, the position of the elastic sheet connection structure 30 in the assembly groove 21 can be limited to further prevent relative displacement between the second connection end 32 and the insulating member 20, so as to facilitate the further connection and fixation of the elastic sheet connection structure 30 and the insulating member 20.

[0123] Among them, the engaging block 331 can be constituted by a protruding portion extending from the connecting portion 33, or can be formed by arranging a groove on the connecting portion 33. In this embodiment, the structure and formation method of the engaging block 331 are not further limited.

[0124] Alternatively, other limiting structures such as limiting protrusions can also be provided in the assembly groove 21. Correspondingly, a limiting groove adapted to the limiting protrusion is provided on the elastic sheet connection structure 30.

[0125] Among them, as Figure 11 and Figure 12 shown in, the first contact portion 311 is an elastic arm or an elastic protrusion. In this way, while ensuring elastic abutment and conduction between the first contact portion 311 and the first conductor 13, the structure of the first contact portion 311 can be made more diverse.

[0126] To facilitate elastic abutment and conduction between the first contact portion 311 and the first conductor 13, an elastic contact point 3112 is further provided on the first contact portion 311. In this way, the first contact portion 311 can abut and conduct with the first conductor 13 through the elastic contact point 3112.

[0127] Among them, the first connection end 31 includes a connection seat 312 and a first contact portion 311 provided on the connection seat 312. One end of the first contact portion 311 is connected to the connection seat 312, and there is a gap between the other end of the first contact portion 311 and the connection seat 312. This can make the first contact portion 311 have a certain elasticity, so that under the action of an external force, the first contact portion 311 can abut against the first conductor 13 such as an FPC antenna, and when the external force disappears, the first contact portion 311 can automatically reset.

[0128] To prevent the first contact portion 311 from shifting relative to the connection seat 312 under the action of an external force, referring to Figure 11 and Figure 12 shown in, two oppositely arranged limiting portions 313 are further provided on the first connection end 31, and the first contact portion 311 is located between the two limiting portions 313. In this way, the first contact portion 311 can be limited by the limiting portions 313 to prevent excessive position shift when the first contact portion 311 moves relative to the first connection end 31 under the action of an external force. In addition, the limiting portions 313 can also play a certain guiding role in the movement of the first contact portion 311 relative to the first connection end 31.

[0129] Specifically, a limiting block 3111 protruding towards the limiting portion 313 is provided at the edge of the first contact portion 311. The limiting block 3111 is located inside the limiting portion 313 and within the groove body 3131 of the limiting portion 313. In this way, when the first contact portion 311 moves relative to the connection base 312, the limiting block 3111 can be restricted within the limiting portion 313, thereby realizing the limiting and guiding functions for the first contact portion 311.

[0130] It should be understood that in order to facilitate the connection of the first conductor 13 and the second conductor 14, the elastic sheet connection structure 30 can be made of a conductor material. Exemplarily, the conductor material includes but is not limited to metal materials such as aluminum alloy, magnesium alloy, or stainless steel.

[0131] As a possible implementation manner, the first connection end 31, the connection portion 33, and the second connection end 32 can be made of one or more conductor materials and prepared by an integral molding process, so that the elastic sheet connection structure 30 has a high structural strength.

[0132] Alternatively, as another possible implementation manner, the first connection end 31, the connection portion 33, and the second connection end 32 can also be independent structures and connected to each other through processes such as welding. In this embodiment, the formation manner of the elastic sheet connection structure 30 is not further limited.

[0133] It should be noted that in addition to conducting the first conductor 13 and the second conductor 14, the elastic sheet connection structure 30 in the embodiments of the present application can also connect any objects that need to be conducted within the electronic device by adopting different structures of the first connection end 31.

[0134] By providing the second connection end 32 on the elastic sheet connection structure 30 in the embodiments of the present application, on the basis of realizing the conduction of the first conductor 13 and the second conductor 14, it is not only possible to facilitate the detachable connection between the elastic sheet connection structure 30 and the insulating member 20, realize the fixation of the elastic sheet connection structure 30 within the electronic device, and help reduce the manufacturing cost of the electronic device, but also can use the insulating member 20 inside the electronic device to fix the first connection end 31, so that the elastic sheet connection structure 30 has more choices for the installable positions within the electronic device.

[0135] In the description of the embodiments of the present application, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0136] The terms "first", "second", "third", "fourth", etc. (if any) in the specification, claims and the above-mentioned drawings of the embodiments of the present application are used to distinguish similar objects and do not necessarily have to be used to describe a specific order or sequence.
