Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a spring connection structure and an electronic device. Background Art

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

[0004] At present, the antenna of electronic devices such as mobile phones is usually set on the shell of the mobile phone. For example, the flexible circuit board FPC antenna is generally located on the head and bottom of the middle frame and covers the 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 spring clip, so that the FPC antenna and the middle frame reference ground are contacted and connected through the spring clip. Among them, the spring clip 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, the shrapnel is welded to the middle frame of the mobile phone, which will result in a higher manufacturing cost of the mobile phone. Summary of the invention

[0006] The present application provides a spring connection structure and an electronic device, which are helpful to reduce the manufacturing cost of the electronic device.

[0007] A first aspect of an embodiment of the present application provides a spring-type connection structure, which is applied to an electronic device. The spring-type connection structure includes a first connection end and a second connection end 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 insulating part inside the electronic device, and the second connection end abuts and conducts with a second conductor inside the electronic device.

[0008] The embodiment of the present application sets a second connection end on the spring-type connection structure, and connects the second connection end to the first connection end, so that 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 in the electronic device through the second connection end, thereby achieving conduction between the first conductor and the second conductor, so as to form a signal transmission path from the first conductor to the second conductor. At the same time, compared with the existing spring-type fixing method, the embodiment of the present application, through the setting of the second connection end, can facilitate the detachable connection between the spring-type connection structure and the insulating member, realize the fixing of the spring-type connection structure in the electronic device, and help reduce the manufacturing cost of the electronic device. On the other hand, it can use the insulating member inside the electronic device to fix the first connection end, so that the spring-type connection structure has more choices for the installation position in the electronic device.

[0009] In a possible implementation, the second connection end is detachably connected to the insulating member and the second conductor via a fastener. In this way, the spring-type connection structure is fixed in the electronic device, abutted against and connected to the first conductor and the second conductor, without having to fix the spring-type connection structure by welding, so as to facilitate the fixation of the spring-type connection structure in the electronic device, which 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 via a 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 a fastener to pass through is provided on the second connection end, and the fastener passes through the through hole and the insulating member to connect the second connection end and the second conductor.

[0011] In this way, by providing the through hole, it is possible to facilitate the fastener to pass through the second connecting end, so as to achieve a detachable connection between the second connecting end and the second conductor.

[0012] In a possible implementation, the second connection end covers a portion of the surface of the insulating member, and abuts against and conducts with the second conductor. In this way, by covering the second connection end on a portion of the surface of the insulating member, it is possible to facilitate the abutment and conduction between the second connection end and the second conductor, thereby facilitating conduction between the first conductor and the second conductor.

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

[0014] In this way, by setting the second contact portion, on the one hand, the second connection end can be connected to the second conductor, thereby realizing the conduction between the first conductor and the second conductor; on the other hand, it can be clamped with the insulating member, so that the fixation of the spring connection structure and the insulating member is more secure, thereby further enhancing the stability and reliability of the conduction between the first conductor and the second conductor.

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

[0016] In this way, the contact area between the second contact portion and the second conductor can be increased, so that the connection between the second connection end and the second conductor is more stable and reliable, thereby further enhancing the stability and reliability of the conduction between the first conductor and the second conductor.

[0017] In a possible implementation manner, the second contact portion includes a connecting section, the connecting section is connected between the first end and the second end, and an accommodating space for accommodating the insulating member is formed between the second contact portion and the substrate.

[0018] In this way, by setting up the accommodating space, on the one hand, the second end of the second contact portion can be covered on the insulating member to facilitate the clamping connection between the second connection end and the insulating member, and on the other hand, the second end of the second contact portion can be tightly connected to the second conductor through the insulating member to enhance the stability and reliability of the connection between the second contact portion and the second conductor.

[0019] In a possible implementation, the second end of the second contact portion is a plate-like structure parallel to the substrate. By providing the plate-like structure, not only can the contact area between the second end of the second contact portion and the second conductor be increased, but the insulating member can also be kept at the same level, so that the first contact portion is always in contact with and conductive to the first conductor.

[0020] In a possible implementation, the second contact portion includes an inserting section inserted into the insulating member, the inserting section extends from an edge of the second end, and the inserting section is inserted into the insulating member.

[0021] In this way, by setting the plug-in section, the fixing effect of the second connecting end on the insulating member can be strengthened to achieve a stable connection between the spring connection structure and the insulating member, thereby further enhancing the stability and reliability of the conduction between the first conductor and the second conductor.

[0022] In a possible implementation, the edge of the substrate is further provided with a clamping portion, which is clamped with the edge of the insulating member. The provision of the clamping portion can further prevent the insulating member and the second connection end from moving relative to each other, facilitate the further connection and fixation with the insulating member, and ensure the stability and reliability of the conduction between the first conductor and the second conductor.

[0023] In a possible implementation, at least two engaging parts are further provided on the edge of the substrate, and the engaging parts 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 parts to prevent the second connection end from moving relative to the insulating member.

[0024] In a possible implementation, the engaging portions are arranged on both sides of the second contact portion, so as to facilitate the arrangement of the spring connection structure on the insulating member while ensuring the engaging portions are engaged with the insulating member.

[0025] In a possible implementation, the engaging portion is a folded edge on the edge of the substrate that is bent toward the insulating member. Thus, the folded edge can facilitate the engagement between the second connection end and the insulating member.

[0026] In a possible implementation, the spring connection structure further includes a connection portion, and the first connection end is connected to the second connection end via the connection portion. Thus, by setting the connection portion, the position of the first contact portion on the spring connection structure can be adjusted, so that the positional freedom of the first contact portion on the spring connection structure is higher.

[0027] In a possible implementation, the first contact portion is an elastic arm or an elastic protrusion, so that the structure of the first contact portion can be more diversified while ensuring that the first contact portion abuts and conducts with the first conductor.

[0028] In a possible implementation, the first connection end is further provided with two oppositely disposed limiting portions, 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 to avoid excessive positional displacement when the first contact portion moves relative to the first connection end under the action of an external force.

[0029] A second aspect of an embodiment of the present application provides an electronic device, which includes a shell, a first conductor and a second conductor. An insulating part and a spring connection structure as described above are provided in the shell. The spring connection structure is detachably connected to the second conductor through the insulating part. At least one of the first conductor and the second conductor is provided on the shell. The first conductor is in contact with and conductive to the second conductor through the spring connection structure.

[0030] In the embodiment of the present application, the spring clip connection structure is detachably connected to the second conductor through an insulating member. In this way, while the spring clip connection structure realizes conduction between the first conductor and the second conductor to improve the anti-electromagnetic interference capability of the electronic device, the insulating member can be used as a fixing structure of the spring clip connection structure to fix the spring clip connection structure inside the electronic device. There is no need to weld the spring clip connection structure to the shell, which not only facilitates the fixing of the spring clip connection structure and reduces the manufacturing cost of the electronic device, but also allows more options for the installation position of the spring clip connection structure in the electronic device.

[0031] In a possible implementation, an assembly groove is provided on the insulating member, and the spring connection structure is provided in the assembly groove. In this way, by providing the assembly groove, the spring connection structure is assembled, and the positional freedom of the first contact portion on the spring connection structure is increased, and the thickness of the electronic device is not affected.

[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 the housing.

[0033] In this way, the flexible circuit board antenna or the backlight bracket can be abutted against and connected to the reference ground through the spring 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, so that the speaker box or the insulating bracket can be used to fix the spring connection structure, which helps to further reduce the manufacturing cost of the electronic device.

[0054] At present, in electronic devices such as mobile phones, it is usually necessary to connect the antenna and the middle frame reference ground in the mobile phone, so that the middle frame reference ground becomes the zero potential point of the antenna and the like, and form a signal transmission path between the antenna and the middle frame reference ground to avoid the middle frame reference ground from affecting the performance of the antenna and improve the anti-electromagnetic interference ability 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 in the mobile phone.

[0055] The antennas in existing electronic devices such as mobile phones are usually arranged on the shell of the mobile phone. Taking the FPC antenna as an example, the FPC antenna is usually arranged on the head and bottom of the middle frame of the shell and covers the four corners of the middle frame. In order to achieve the connection and conduction between the FPC antenna and the middle frame reference ground in the mobile phone, a spring is usually arranged between the FPC antenna and the middle frame reference ground in the mobile phone. Since the spring is usually made of conductive materials such as metal, when one end of the spring is in contact with the FPC antenna and the other end is in contact with the middle frame reference ground, the FPC antenna can be connected and conducted with the middle frame reference ground.

[0056] In order to fix the spring clip in the mobile phone, the common practice is to fix the spring clip on the middle frame of the mobile phone by welding. Then, through holes are opened on the spring clip, the middle frame and the reference ground of the middle frame, and screws are inserted into the through holes to connect the spring clip, the middle frame and the reference ground, so that the spring clip is screwed to the reference ground of the middle frame. In this way, while the spring clip is fixed, the FPC antenna can be stably connected and conductive with the reference ground of the middle frame.

[0057] However, in order to ensure the effectiveness and reliability of the connection between the FPC antenna and the reference ground of the middle frame, high requirements are placed on the welding process and welding effect. Due to the limitations of the welding process and welding effect, it is costly to weld the spring clips to the middle frame, which will result in a high manufacturing cost for the mobile phone. In addition, as electronic devices continue to develop in the direction of high screen-to-body ratio and thinness, the structure of the middle frame has been continuously compressed, and the space on the middle frame where spring clips can be welded and holes can be opened is relatively limited. This restricts the installation of the spring clips on the middle frame to a certain extent, limiting the freedom of the installation position of the spring clips on the middle frame.

[0058] In view of this, the embodiment of the present application provides a spring-type connection structure and an electronic device, by setting a second connection end on the spring-type connection structure, and connecting and conducting the second connection end with the first connection end of the spring-type connection structure, so that 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 in the electronic device through the second connection end, thereby achieving conduction between the first conductor and the second conductor. At the same time, compared with the existing spring-type welding fixing method, the embodiment of the present application, through the setting of the second connection end, can not only facilitate the detachable connection between the spring-type connection structure and the insulating member, and achieve the fixation of the spring-type connection structure in the electronic device, which helps to reduce the manufacturing cost of the electronic device, but also can use the insulating member inside the electronic device to fix the second connection end and the spring-type connection structure, so that the spring-type connection structure has more choices of installation positions in the electronic device, so as to achieve reliable grounding of the first conductors of different structures in the electronic device.

[0059] In this embodiment, the electronic device may include but is not limited to 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, and any other devices with grounding and electrical connection requirements.

[0060] The following describes the electronic device in the embodiments of the present application by taking a mobile phone as an example.

[0061] Example

[0062] Figure 1a This is a schematic diagram of the structure of the bottom wall end of a mobile phone provided in an embodiment of the present application. Figure 1b This is a schematic diagram of the structure of the bottom wall end of a mobile phone provided in an embodiment of the present application. Figure 2 for Figure 1a The schematic diagram of the structure of the mobile phone A after being cut from the BB direction and the DD direction. Figure 3 for Figure 2 An enlarged schematic diagram of the E part of the mobile phone in FIG. Figure 4 for Figure 1a The schematic diagram of the structure of the mobile phone A after cutting from the CC direction and the DD direction. Figure 5 for Figure 4 The bottom wall end can be understood as the end of the mobile phone that contacts the work surface when the mobile phone is placed vertically on the work surface. It should be understood that Figure 1b From another perspective Figure 1aDifferent cutting directions for better understanding Figure 1a Different cutting positions in the.

[0063] Figures 2 to 5 exist Figure 1a Based on the above, schematic diagrams of the structures after cutting at different positions of the mobile phone along the length direction of the mobile phone are provided. Figure 2 and Figure 3 As can be seen in the figure, 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 a spring connection structure 30 as described above are provided in the housing 10, and at least one of the first conductor 13 and the second conductor 14 is provided on the housing 10. The spring connection structure 30 is detachably connected to the second conductor 14 through the insulating member 20, and the first conductor 13 is in contact with and connected to the second conductor 14 through the spring connection structure 30. In this way, the spring connection structure 30 can ensure that the first conductor 13 and the second conductor 14 are connected, and a signal transmission path is formed between the first conductor 13 and the second conductor 14, so as to improve the anti-electromagnetic interference capability of the electronic device.

[0064] At the same time, since the spring 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 of the spring connection structure 30, and the spring connection structure 30 is fixed inside the electronic device such as the mobile phone 100. In the embodiment of the present application, there is no need to weld the spring connection structure 30 to the housing 10. Compared with the method of welding the springs to the middle frame 11, it can not only simplify the fixing method of the spring connection structure 30, reduce the fixing cost of the spring connection structure 30, and thus reduce the manufacturing cost of the electronic device, but also make the spring connection structure 30 more selective in the installation position in the electronic device.

[0065] It should be noted that the above-mentioned detachable connection can be understood as the spring-type connection structure 30 being able to be disconnected after being connected to the second conductor 14 through the insulating member 20, so as to facilitate the disassembly of the spring-type connection structure 30. Exemplarily, the spring-type connection structure 30 and at least one of the insulating member 20 and the second conductor 14 can be connected by fastener connection or clamping.

[0066] In order to facilitate the installation of the spring connection structure 30, as shown in FIG. Figure 2 and Figure 3As shown in , the insulating member 20 is provided with an assembly groove 21, and the spring connection structure 30 is arranged in the assembly groove 21. Thus, by providing the assembly groove 21 on the insulating member 20, on the one hand, the spring connection structure 30 can be assembled on the insulating member 20, so as to be detachably connected with the second conductor 14 through the insulating member 20; on the other hand, the spring connection structure 30 can be embedded in the assembly groove 21, so as to avoid the setting of the spring connection structure 30 on the insulating member 20 affecting the thickness of the electronic device.

[0067] Among them, see Figure 2 and Figure 3 As shown, the assembly groove 21 can be provided at the corner of the insulating member 20. In this way, while the spring connection structure 30 is conveniently connected to the insulating member 20 and abuts and conducts with the second conductor 14, it can avoid the adverse effect of the arrangement of the speaker in the speaker box due to the arrangement of the assembly groove 21.

[0068] Wherein, when the insulating member 20 is a non-circular structure, such as a square structure, the corner portion can be understood as the location of the four corners of the square structure.

[0069] refer to Figures 2 to 3 As shown, the insulating member 20 can be a speaker box or other insulating housing in the mobile phone 100. In this way, the existing structure in the mobile phone 100 can be used to fix the spring connection structure 30. On the one hand, there is no need to add an additional fixing structure of the spring connection structure 30 in the electronic device, such as a switching circuit board, which helps to further reduce the manufacturing cost of the electronic device. On the other hand, since the spring connection structure 30 is assembled in the assembly groove 21 at the corner of the speaker box, it will not affect the spatial layout in the electronic device while ensuring the normal use of the speaker.

[0070] It is understandable that the speaker box is an insulating shell made of insulating materials such as plastic. Figure 4 and Figure 5 As shown in FIG. 2 , the assembly groove 21 can be formed by the assembly platform 23 at the corner of the speaker box and the outer side wall 24 of the speaker box. In other words, the assembly groove 21 can be formed on the outer surface of the speaker box.

[0071] Alternatively, in this embodiment, the insulating member 20 may also be an insulating bracket in the housing 10, and the assembly groove 21 may be formed at a corner of the insulating bracket. In other words, the insulating member 20 includes but is not limited to a 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 may correspond to the first conductor 13 and the second conductor 14 , so that when the spring connection structure 30 is disposed in the assembly groove 21 , the first conductor 13 and the second conductor 14 can be easily connected through the spring 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 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 spring connection structure 30 to improve the anti-electromagnetic interference capability of the electronic device.

[0074] Accordingly, the second conductor 14 may be Figure 4 and Figure 5 Alternatively, the second conductor 14 may also be a metal plate in an electronic device such as a mobile phone 100 that can serve as a zero potential point of the first conductor 13. That is, 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 connected to the reference ground on the middle frame 11 through the spring connection structure 30, thereby forming 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. The metal support plate can be a support plate made of alloy materials such as aluminum alloy, magnesium alloy, etc. or other metal materials.

[0076] The middle frame 11 may include a frame 111 and a metal support plate, wherein the frame 111 is arranged around the metal support plate and connected to the edge of the metal support plate. The housing 10 of the electronic device may also include a battery, a circuit board, etc., which are fixed on the metal support plate.

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

[0078] Specifically, refer to Figure 4 and Figure 5As shown, the housing 10 further includes a fixing member 12, which is located on the first conductor 13 and is used to fix the first conductor 13. The edge of the fixing member 12 located in the housing 10 extends toward the direction of the spring connection structure 30 and the insulating member 20 to the assembly groove 21. The spring connection structure 30 can also be as shown in FIG. Figure 2 and Figure 3 As shown in the figure, the spring connection structure 30 is detachably connected to the fixing member 12 through the fastener 40. In this way, under the joint action of the fastener 40 and the fixing member 12, the spring connection structure 30 can be closely fitted with 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 prevent the fastener 40 from affecting the thickness of the electronic device, as Figure 2 and Figure 3 As shown in , the fixing member 12 may also be provided with a groove 121, and the fastener 40 is embedded in the groove 121, and passes through the groove 121 to detachably connect the spring connection structure 30 with the insulating member 20 and the second conductor 14. In this way, while achieving the detachable connection between the fixing members 12 and the fixing members 12, it is possible to avoid the setting of the fastener 40 affecting the thickness of the electronic device.

[0080] The fastener 40 includes but is not limited to screws, bolts or other connecting structures.

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

[0082] When the fixing member 12 is an insulating decorative member, since part of the insulating decorative member is arranged on the frame 111 of the middle frame 11 and fits with 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 spring connection structure 30, the edge of the fixing member 12 located in the housing 10 can also extend toward the middle of the housing 10 to the spring connection structure 30.

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

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

[0085] It is to be understood that the structure illustrated in the embodiment 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 shown in the figure, or combine some components, or separate some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

[0086] In order to reduce the manufacturing cost of electronic devices, the embodiment of the present application provides a spring connection structure 30. The spring connection structure 30 is applied to electronic devices such as mobile phones 100 to replace the springs in existing mobile phones 100. In the following, the mobile phone 100 is taken as an example, in the application scenario where the first conductor 13 is a flexible circuit board antenna and the second conductor 14 is a reference ground on the middle frame 11, combined with Figures 2 to 12 The spring connection structure 30 provided in the embodiment of the present application is specifically described.

Figure 7 for Figure 6 The enlarged diagram of the G part of the mobile phone in the figure, Figure 8 for Figure 7 Schematic diagram of the structure of the mobile phone after removing the FPC antenna.

[0088] Figures 2 to 8 FIG. 1 is a schematic diagram of assembling the spring connection structure 30 in the mobile phone 100. The spring connection structure 30 is applied to electronic equipment. Figure 8 As can be seen in the figure, the spring connection structure 30 includes a first connection end 31 and a second connection end 32 that are connected and conducted 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. In this way, by setting the second connection end 32 on the spring connection structure 30, combined 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 spring connection structure 30 can be regarded as a 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 second conductor 14 affecting the performance of the first conductor 13, which helps to improve the anti-electromagnetic interference capability of the electronic device.

[0089] At the same time, compared with the existing fixing method of spring clip welding, the embodiment of the present application, through the setting of the second connection end 32, on the basis of ensuring that the first contact portion 311 and the first conductor 13 are abutted and conductive, on the one hand, the spring clip connection structure 30 can be detachably connected to the insulating member 20 through the second connection end 32, which is convenient for the connection between the spring clip connection structure 30 and the insulating member 20. While achieving the fixation of the spring clip connection structure 30 in the electronic device, the fixing method of the spring clip connection structure 30 can be simplified, so as to achieve the purpose of reducing the manufacturing cost of the electronic device by reducing the fixing cost of the spring clip connection structure 30; on the other hand, the insulating member 20 inside the electronic device can be used to fix the first connection end 31, and the insulating member 20 can be used as a transfer fixing structure for the second connection end 32 and the spring clip connection structure 30, without welding the first connection end 31 and the spring clip connection structure 30 to the shell 10, so that the spring clip connection structure 30 has more options for the installation position in the electronic device.

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

[0091] The first conductor 13 may be Figure 6 and Figure 7 The flexible circuit board antenna shown in the figure is an FPC antenna, the second conductor 14 is the reference ground on the middle frame 11, and the insulating member 20 is a speaker box. In this way, by arranging the spring connection structure 30 on the speaker box, the FPC antenna can be connected and conducted with the reference ground on the middle frame 11, thereby achieving grounding of the FPC antenna.

[0092] Specifically, Figure 8As shown in the figure, the fixing seat 32 is detachably connected to the insulating member 20 and the second conductor 14 through the fastener 40. In this way, when the spring-type connection structure 30 is arranged in the assembly groove 21, the spring-type connection structure 30 can be fixed on the insulating member 20 through the fastener 40, and abuts and conducts with the first conductor 13 and the second conductor 14, and there is no need to fix the spring-type connection structure 30 by welding, which can simplify the fixing of the spring-type connection structure 30 in the electronic device and help reduce the manufacturing cost of the electronic device.

[0093] In addition, the spring connection structure 30 can be locked with 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, and achieve the purpose of stable grounding of the first conductor 13, such as an FPC antenna.

[0094] In order to facilitate the connection of the fastener 40, the Figure 8 As shown, the second connection end 32 is provided with a through hole 324 for the fastener 40 to pass through, and 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 provision of the through hole 324, it is convenient for the fastener 40 to pass through the second connection end 32 and connect with 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] The through hole 324 may be a threaded hole or other hole through which the fastener 40 can pass, and the through hole 324 may connect the second connection end 32 to the insulating member 20 and the second conductor 14. That is, the through hole 324 includes but is not limited to a screw hole adapted to the fastener 40.

[0096] In order to facilitate the fastener 40 to pass through the insulating member 20 , the insulating member 20 is further provided with the through hole 324 at a position opposite to the through hole 324 for the fastener 40 to pass through.

[0097] It should be understood that the second conductor 14 is further provided with a connection hole (not shown in the figure) at a position opposite to the through hole 324, so that the fastener 40 can be connected to the second conductor 14 at the connection hole after passing through the through hole 324 of the insulating member 20. 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, Figure 2 and Figure 3As shown in the figure, the same fastener 40 can also penetrate the groove 121 of the fixing member 12, and connect the fixing member 12 with 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 abutment degree between the first contact portion 311 and the first conductor 13, and the abutment degree 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, so as to ensure the stable grounding of the first conductor 13.

[0099] The fixing member 12 is also provided with a screw hole, a threaded hole or other hole for connecting the fastener 40 through the groove 121. This makes it easy for the fastener 40 to pass through the fixing member 12 and connect with the spring connection structure 30, the insulating member 20 and the second conductor 14.

[0100] In order to facilitate understanding of the connection between the spring connection structure 30 and the insulating member 20, the present embodiment of the application will Figure 7 The first conductor 13 in the FPC antenna is hidden, forming a Figure 8 The structure shown in . Figure 8 As can be seen in the figure, the second connection end 32 covers part of the surface of the insulating member 20, and abuts and conducts with the second conductor 14. This makes it easier for the second connection end 32 to abut and conduct with the second conductor 14, so that the first conductor 13 can be conducted with the second conductor 14 through the spring connection structure 30, thereby grounding the first conductor 13 and improving the anti-electromagnetic interference capability of the electronic device such as the mobile phone 100.

[0101] Specifically, Figure 8 As shown in , 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 portion of the surface of the insulating member 20, and the second contact portion 322 abuts against and conducts with the second conductor 14. In this way, the second connection end 32 and the second conductor 14 can be conducted through the second contact portion 322, so that the first conductor 13 and the second conductor 14 are conducted. At the same time, the second connection end 32 is snapped with the insulating member 20 through the second contact portion 322. In this way, through the snap connection, the position of the second connection end 32 on the insulating member 20 can be pre-fixed to avoid the position of the second connection end 32 when it is further fixed on the insulating member 20. It is convenient for the second connection end 32 to be further connected to the insulating member 20, such as by fasteners 40. In addition, the second connection end 32 is clamped with the insulating member 20 via the second contact portion 322 , which can make the fixing of the spring connection structure 30 and the insulating member 20 more secure, and help to further enhance the stability and reliability of the conduction between the first conductor 13 and the second conductor 14 .

[0102] refer to Figure 8 As shown in , 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 a side of the second conductor 14 facing the insulating member 20, so that the second connection end 32 abuts against the second conductor 14 through two opposite surfaces, so as to increase the abutment area between the second contact portion 322 and the second conductor 14, so that the connection between the second connection end 32 and the second conductor 14 is more stable and reliable, and the first conductor 13 and the second conductor 14 can be connected with high stability and reliability, so as to achieve the purpose of reliable grounding of the first conductor 13, such as the FPC antenna.

[0103] Fig. 9 A method provided in the embodiment of the present application Figure 8 Schematic diagram of the assembly of the spring connection structure and the insulating part. Fig.10 Another embodiment of the present application provides Figure 8 Schematic diagram of the assembly of the spring connection structure and the insulating part. Fig.11 A schematic diagram of a spring connection structure provided in an embodiment of the present application at a first viewing angle is shown. Fig.12 A schematic structural diagram of a spring connection structure provided in an embodiment of the present application at a second viewing angle.

[0104] Among them, reference Figures 9 to 12 As shown, the second contact portion 322 includes a connecting section 3224, the connecting section 3224 is connected between the first end 3221 and the second end 3222, and 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, by setting the receiving space 326 in the second connecting end 32, the second connecting end 32 can be formed in the Y direction as shown in FIG. Fig.11 and Fig.12 The double-layer structure shown in the figure can be used to dispose the insulating member 20 in the accommodating space 326, so that the second end 3222 is formed and located between the insulating member 20 and the second conductor 14, which can increase the abutment area between the second connecting end 32 and the second conductor 14, and at the same time, the second end 3222 of the second contact portion 322 can be tightly connected to the second conductor 14 under the action of gravity of the insulating member 20, so as to further enhance the stability and reliability of conduction between the second contact portion 322 and the second conductor 14.

[0105] In addition, by providing a space 326 in 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, thereby achieving the snap connection between the second connection end 32 and the insulating member 20, so that the positions of the second connection end 32 and the insulating member 20 are relatively fixed, so as to facilitate further connection between the second connection end 32 and the insulating member 20.

[0106] It should be noted that, by disposing the connecting section 3224 , a gap can be provided between the second end 3222 and the substrate 321 , so that an accommodating space 326 is formed between the second contact portion 322 and the substrate 321 .

[0107] For example, Fig.11 and Fig.12 As shown in , the second end 3222 of the second contact portion 322 is a plate-like structure parallel to the substrate 321. By setting the plate-like structure, on the one hand, the contact 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 can be closely attached to 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 accommodating space 326 can be improved, so that the insulating member 20 can be kept at the same level, so as to avoid the position shift 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 first contact portion 311 possibly being separated from the first conductor 13, affecting the abutment between 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 second end 3222 of the second contact portion 322 is provided with the above-mentioned through hole 324 for the fastener 40 to pass through, 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 optional implementation, Fig.11 and Fig.12 As shown in FIG. 1 , the second contact portion 322 includes an inserting section 3223 inserted into the insulating member 20. The inserting section 3223 is arranged near the edge of the electronic device and extends from the edge of the second end 3222. The inserting section 3223 is inserted and connected to the surface of the insulating member 20 (such as Fig. 9 and Fig.10Thus, on the basis of the second connection end 32 being clamped with the insulating member 20 and connected with the fastener 40, the second connection end 32 can be fixed on the insulating member 20 by inserting the plug section 3223 into the insulating member 20, so as to further prevent the second connection end 32 and the insulating member 20 from moving relative to each other, so as to achieve a stable connection between the spring connection structure 30 and the insulating member 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] In order to facilitate the insertion of the plug-in section 3223 into the insulating part 20, an insertion hole (not shown in the figure) may also be provided on the assembly platform 23 of the insulating part 20. The insertion hole may be exposed on the surface of the assembly platform 23, and the plug-in section 3223 may 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 portion 322 is located on the side of the insulating member 20 opposite to the substrate 321, that is, the second end 3222 is located on the side of the insulating member 20 facing the substrate 321. In order to achieve the insertion of the plug-in section 3223 into the assembly platform 23, the plug-in section 3223 should be a folded edge on the second end 3222 of the second contact portion 322 facing the substrate 321. In this way, when the plug-in section 3223 is inserted into the insulating member 20, it will not affect the abutment and conduction between the second contact portion 322 and the second conductor 14.

[0112] As a possible implementation, Fig.11 and Fig.12 As shown in , the second end 3222 of the second contact portion 322 can partially extend along the edge of the substrate 321 to the side of the insulating member 20 opposite to the substrate 321. In this way, by adjusting and changing the extension direction of the second end 3222 for multiple times, the above-mentioned through hole 324 can be formed in the second end 3222, and the plug section 3223 can be formed at the end of the second end 3222.

[0113] Alternatively, as another possible implementation, the second end 3222 of the second contact portion 322 may also extend as a whole along the edge of the substrate 321 to the side of the insulating member 20 opposite to the substrate 321. Then, the through hole 324 is opened in the second end 3222, and the plug-in section 3223 is formed by mechanical processing or the like. In this embodiment, the extension method of the second end 3222 of the second contact portion 322, and the formation method of the through hole 324 and the plug-in section 3223 are not further limited.

[0114] In order to further enhance the clamping effect between the second connecting end 32 and the insulating member 20, refer to Fig.11 and Fig.12As shown, the edge of the substrate 321 is further provided with a snap-fit ​​portion 323, which snaps into place with the edge of the insulating member 20 (as shown in FIG. Fig. 9 and Fig.10 As shown in ). In this way, under the joint action of the second contact portion 322 and the engaging portion 323, the second connection end 32 can be restricted from moving relative to the insulating member 20, so as to avoid the second connection end 32 from moving relative to the insulating member 20 when the second connection end 32 is further connected to the insulating member 20, thereby enhancing the engaging effect between the second connection end 32 and the insulating member 20, facilitating the further connection and fixation between the second connection end 32 and the insulating member 20, and ensuring 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 the FPC antenna.

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

[0116] As a possible implementation, the engaging portions 323 may be distributed on both sides of the second contact portion 322. In this way, while ensuring that the engaging portions 323 are engaged with the insulating member 20, it is convenient to arrange the spring connection structure 30 on the insulating member 20.

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

[0118] Exemplarily, the engaging portion 323 may be a folded edge on the edge of the substrate 321 that is bent toward the insulating member 20. This not only facilitates the engagement of the second connecting end 32 with the insulating member 20, but also simplifies the structure of the second connecting end 32 and the spring connection structure 30, which helps to further reduce the manufacturing cost of the electronic device.

[0119] Further, such as Fig.11 and Fig.12As shown in the figure, the substrate 321 and the second end 3222 of the second contact portion 322 are both provided with a limiting protrusion 325 on the side facing the second conductor 14. Correspondingly, the insulating member 20 is provided with a recessed portion (not shown in the figure) adapted to the limiting protrusion 325. When the second connecting end 32 is assembled on the insulating member 20, the limiting protrusion 325 is located in the recessed portion, which can further enhance the stability of the connection between the second connecting end 32 and the insulating member 20 and the second conductor 14, and can also prevent the second connecting end 32 from moving relative to the insulating member 20.

[0120] As a possible implementation, refer to Fig.11 and Fig.12 As shown, the spring connection structure 30 may further include a connection portion 33, and the first connection end 31 is connected to the second connection end 32 via 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 Fig. 9 and Fig.10 The position of the first contact portion 311 on the spring-clip connection structure 30 is adjusted, so that the first contact portion 311 on the spring-clip connection structure 30 has a higher degree of freedom in setting the position, 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 spring-clip connection structure 30 can be applied in more scenarios in the electronic device and has a wider applicability.

[0121] The connecting portion 33 may be a connecting arm. For example, the connecting arm may be a connecting plate or a connecting rod. One end of the connecting arm may be connected to the connecting seat 312 of the first connecting end 31, and the other end may be connected to the base plate 321 of the second connecting end 32, so that the structure of the spring connection structure 30 can be simplified while ensuring the connection between the first connecting end 31 and the second connecting end 32.

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

[0123] The engaging block 331 may be formed by a protrusion extending from the connecting portion 33, or by a groove provided on the connecting portion 33. In this embodiment, the structure and formation of the engaging block 331 are not further limited.

[0124] Alternatively, other limiting structures, such as limiting protrusions, may be provided in the assembly groove 21. Correspondingly, the spring connection structure 30 is provided with limiting grooves, etc., which are matched with the limiting protrusions.

[0125] Among them, Fig.11 and Fig.12 As shown in , the first contact portion 311 is an elastic arm or an elastic protrusion. In this way, while ensuring that the first contact portion 311 elastically abuts and conducts with the first conductor 13, the structure of the first contact portion 311 can be more diversified.

[0126] In order to facilitate the elastic contact 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 , so that the first contact portion 311 can be in contact and conduction with the first conductor 13 through the elastic contact point 3112 .

[0127] The first connection end 31 includes a connection base 312 and a first contact portion 311 disposed on the connection base 312, one end of the first contact portion 311 is connected to the connection base 312, and a gap is provided between the other end of the first contact portion 311 and the connection base 312. In this way, the first contact portion 311 can 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] In order to prevent the first contact portion 311 from being offset relative to the connecting seat 312 under the action of external force, Fig.11 and Fig.12 As shown, two limiting portions 313 are arranged opposite to each other 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 the first contact portion 311 from being excessively offset 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 stopper 3111 protruding toward the stopper 313 is provided on the edge of the first contact portion 311, and the stopper 3111 is located inside the stopper 313 and inside the groove 3131 of the stopper 313. In this way, when the first contact portion 311 moves relative to the connecting seat 312, the stopper 3111 can be restricted inside the stopper 313, thereby achieving the limiting and guiding effects on 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 spring 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, the first connection end 31 , the connection portion 33 and the second connection end 32 may be made of one or more conductive materials and manufactured through an integrated molding process, so that the spring connection structure 30 has a higher structural strength.

[0132] Alternatively, as another possible implementation, the first connection end 31, the connection portion 33 and the second connection end 32 may also be independent structures, connected to each other by welding or other processes. In this embodiment, the formation method of the spring 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 spring connection structure 30 in the embodiment of the present application can also be connected to any object that needs to be conducted in the electronic device by using the first connection end 31 with different structures.

[0134] The embodiment of the present application provides a second connection end 32 on the spring-type connection structure 30. On the basis of achieving conduction between the first conductor 13 and the second conductor 14, it is not only possible to facilitate the detachable connection between the spring-type connection structure 30 and the insulating member 20, and fix the spring-type connection structure 30 in the electronic device, which helps to reduce the manufacturing cost of the electronic device, but also can utilize the insulating member 20 inside the electronic device to fix the first connection end 31, so that the spring-type connection structure 30 has more choices for the installation position in the electronic device.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

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