Description

Technical Field

[0001] This application relates to the field of electronic product technology, and in particular to an electronic device. Background Technology

[0002] Electronic devices have connector sockets that correspond to electrical connector modules. In fast charging scenarios, these modules need to meet certain current-carrying requirements. Soldering a spring contact to a small board bracket for electrical connection to the connector module would increase the connector module's grounding points, thus meeting the current-carrying requirements for fast charging. However, soldering the spring contact to the small board bracket is not conducive to thinner designs of electronic devices. Summary of the Invention

[0003] This application provides an electronic device to solve the technical problem that welding spring contacts to electrical connector modules on a small board bracket for electrical connection is not conducive to the thinning design of electronic devices.

[0004] The technical solution is as follows:

[0005] The first aspect of this application provides an electronic device, comprising:

[0006] Small board support, with openings provided on the small board support;

[0007] The flexible plate structure is connected to the wall of the opening;

[0008] An electrical connector module, with a flexible plate structure electrically connected to the electrical connector module to form a grounding point for the electrical connector module.

[0009] In this embodiment, an opening is provided on the small board support and the elastic plate structure is connected to the wall of the opening. This is to enable the small board support to be electrically connected to the electrical connector module, while minimizing the space occupied in the thickness direction of the electronic device due to the introduction of the elastic plate structure, so as to facilitate the thinning design of the electronic device.

[0010] In some implementations, the elastic plate structure and the small plate support are integrally formed.

[0011] In this implementation, the elastic plate structure can be directly stamped on the small plate bracket. The stamping process is simple, precise, and produces a good product surface quality. Since the elastic plate structure and the small plate bracket are stamped together, the connection between the elastic plate structure and the small plate bracket has high strength. In addition, the form of the elastic plate structure 2 is more flexible and diverse in design.

[0012] In some implementations, the flexible plate structure is directly electrically connected to the electrical connector module, or the electrical connector module is indirectly in contact with the flexible plate structure through a circuit board.

[0013] In this implementation, the connection method between the elastic plate structure and the electrical connector module is determined according to the structural components within the electronic device; that is, the connection method between the elastic plate structure and the electrical connector module is not limited to one method.

[0014] In some implementations, the electronic device also includes a flexible circuit board and a reinforcing sheet. The reinforcing sheet and electrical connector module are disposed on both sides of the flexible circuit board. The reinforcing sheet is electrically connected to the flexible circuit board, and the elastic plate structure abuts against the reinforcing sheet.

[0015] In this implementation, by setting reinforcing sheets on the flexible circuit board, the reliability and durability of the flexible circuit board are improved, and the flexible circuit board is prevented from being easily damaged when the elastic plate structure directly abuts against it.

[0016] In some implementations, a first mating area and a second mating area are formed on the small board support. An opening is provided in the first mating area. The second mating area is connected to the first mating area and is located on the outer periphery of the first mating area. The side of the first mating area away from the electrical connector module is the upper side of the first mating area, and the side of the second mating area away from the electrical connector module is the upper side of the second mating area.

[0017] In some implementations, the upper side of the first mating region and the upper side of the second mating region are on the same plane.

[0018] In this implementation, there is no need to stamp a clearance groove for connecting the spring sheet on the small board bracket. Since the upper side of the first mating area and the upper side of the second mating area are on the same horizontal plane, adding an elastic plate structure to the small board bracket does not increase the space occupied in the thickness direction of the electronic device.

[0019] In some implementations, the first mating region is recessed relative to the second mating region on the side away from the electrical connector module.

[0020] In this implementation, although the first mating area is recessed away from the electrical connector module relative to the second mating area, the small board support and the spring piece are avoided from overlapping in the thickness direction of the electronic device by setting the elastic plate structure to connect with the hole wall of the opening. This achieves electrical connection between the small board support and the electrical connector module while minimizing the space occupied in the thickness direction of the electronic device caused by the introduction of the elastic plate structure.

[0021] In some implementations, the first mating region is recessed relative to the second mating region on the side away from the electrical connector module, and the height difference between the upper side of the first mating region and the upper side of the second mating region is less than the thickness of the elastic plate structure.

[0022] In this implementation, since the installation height of the elastic plate structure is greater than that of the spring sheet, the elastic plate structure has a better elasticity performance than the spring sheet. Therefore, in this embodiment, not only can the space occupied in the thickness direction of the electronic device be reduced, but also a stable electrical connection between the elastic plate structure and the electrical connector module can be achieved.

[0023] In some implementations, the flexible plate structure includes a flexible arm that extends at an angle toward the electrical connector module.

[0024] In this implementation, when there are multiple elastic arms, multiple grounding points of the electrical connector module can be formed between the elastic plate structure and the electrical connector module, which can further improve the current carrying capacity.

[0025] In some implementations, the flexible arm is provided with a contact protrusion that is close to the free end of the flexible arm and faces the electrical connector module.

[0026] In this implementation, contact protrusions are provided on the elastic arm to facilitate better electrical connection between the elastic plate structure and the electrical connector module.

[0027] In some implementations, the elastic arm is connected to the wall of the opening.

[0028] In this implementation, by setting the elastic arm to connect with the hole wall, the structure of the elastic plate is simplified, and it is also beneficial to increase the length of the elastic arm.

[0029] In some implementations, an elastic arm is provided on each of the two hole walls opposite to the opening.

[0030] In this implementation, by setting an elastic arm on each of the two opposite holes, the space of the hole can be fully utilized.

[0031] In some implementations, the elastic plate structure also includes a connecting plate connected to the wall of the opening, and the elastic arm is disposed on the connecting plate.

[0032] In this implementation, an elastic arm is connected to the hole wall of the opening via a connecting plate, providing another form for the elastic plate structure.

[0033] In some implementations, the two ends of the connecting plate are connected to the two hole walls opposite to the opening, and there are two elastic arms, which are respectively set on opposite sides of the connecting plate.

[0034] In this implementation, the two ends of the connecting plate are connected to the two hole walls opposite to the opening, which is beneficial to the stability of the structure.

[0035] In some implementations, the cross-sectional area of ​​the elastic arm decreases from the direction away from the free end of the elastic arm to the direction closer to the free end of the elastic arm.

[0036] In this implementation, the cross-sectional area of ​​the elastic arm decreases from the direction away from the free end of the elastic arm to the direction closer to the free end of the elastic arm, and the cross-sectional area at the connection end of the elastic arm is the largest, which is beneficial to the stable connection of the elastic arm. As the cross-sectional area of ​​the elastic arm decreases towards the free end of the elastic arm, it is beneficial to allow the elastic arms to avoid each other when the elastic plate structure includes multiple elastic arms.

[0037] In some implementations, the side of the elastic plate structure facing away from the electrical connector module does not protrude from the plate surface of the small board support around the opening in the thickness direction of the small board support.

[0038] In this implementation, the side of the elastic plate structure facing away from the electrical connector module does not protrude from the small board bracket located around the opening, so as to avoid the space occupied in the thickness direction of the electronic device when the side of the elastic plate structure facing away from the electrical connector module protrudes from the small board bracket located around the opening.

[0080] This embodiment provides an electronic device 100, including but not limited to mobile phones, notebook computers, tablet personal computers, laptop computers, personal digital assistants, wearable devices, mobile devices, or Bluetooth speakers. That is, this embodiment does not impose any special limitations on the specific form of the electronic device 100.

[0081] The electronic device 100 includes an electrical connector module 3, which can serve as a charging interface, headphone jack, data transmission interface, etc. Other electronic devices 100 or structures can be connected to the electrical connector module 3 through a mating connector, thereby enabling electrical connection between the other electronic devices 100 or structures and the electronic device 100 provided in this embodiment.

[0082] Electrical connector module 3 is electrically connected to each working module of electronic device 100. These working modules include power modules, camera modules, audio modules, display modules, etc. Electrical connector module 3 provides power or data transmission to each working module of electronic device 100. For example, a charger connector can be plugged into electrical connector module 3 to power each working module of electronic device 100; in this case, electrical connector module 3 acts as a charging interface for electronic device 100. Alternatively, other electronic devices 100 can be connected to electrical connector module 3 via connecting cables to enable signal transmission between electronic device 100 and other external structures; in this case, electrical connector module 3 acts as a data transmission interface.

[0083] In one example, the electronic device 100 includes a main circuit board (hereinafter referred to as the motherboard) and a small circuit board (hereinafter referred to as the small board 4). The electrical connector module 3 is electrically connected to the small board 4, and the small board 4 is electrically connected to the motherboard. Some working modules, such as power supply module, camera module, audio module, display module, etc., are connected to the motherboard.

[0084] Please see Figure 1 This diagram illustrates the appearance of the electronic device 100 when it is a mobile phone. For ease of description, the width direction of the electronic device 100 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. The X-axis, Y-axis, and Z-axis are mutually perpendicular. Along the Y-axis, the two ends of the electronic device 100 are defined as the top and bottom, respectively. Figure 1 In the example, the bottom of the electronic device 100 is provided with a connector socket 51, and the electrical connector module 3 mates with the connector socket 51. That is, the charging connector of the charger can be inserted into the electronic device 100 through the connector socket 51 to connect with the electrical connector module 3. See also Figure 1 This illustrates the connection between electrical connector module 3 and small board 4. It should be noted that... Figure 1 The structure of the electrical connector module 3 and the small board 4 shown, as well as their positions within the electronic device 100, are for illustrative purposes only and do not constitute a limitation on the structure of the electrical connector module 3 and the small board 4 or their positions within the electronic device 100.

[0085] In one example, the electronic device 100 includes a middle frame 5 on which a connector socket 51 is formed. See also Figure 2 , Figure 2 This is a partial structural diagram of electronic device 100, illustrating its internal structure. Figure 2 The diagram illustrates the connector socket 51 on the middle frame 5, and shows the electrical connector module 3 inserted into the connector socket 51 through the inside of the middle frame 5.

[0086] In one example, see Figures 3-4 , Figure 3 This is a partial structural diagram of electronic device 100. Figure 4 for Figure 3 The small board bracket 1 is in an exploded state. The electronic device 100 also includes a small board bracket 1, a small board 4 is connected to the small board bracket 1, and the small board bracket 1 is connected to the housing of the electronic device 100, for example, the small board bracket 1 is connected to the middle frame 5.

[0087] In one example, electrical connector module 3 is a Type-C interface connector. It is understood that in some embodiments, electrical connector module 3 may also be an interface connector other than a Type-C interface connector.

[0088] In one example, the electrical connector module 3 includes a connector housing and an electrical connector body. The electrical connector body is disposed within and fixed to the connector housing, meaning the connector housing covers a portion of the surface of the electrical connector body to protect the electrical connector module 3.

[0089] In some embodiments, the connector housing may be made of metal material, which can serve as electromagnetic shielding, thereby preventing other structures outside the electrical connector module 3 from affecting the signal transmission of the electrical connector module 3.

[0090] In one example, a fixing end 31 is formed on the connector housing to fix the electrical connector module 3 to the electronic device 100 via the fixing end 31.

[0091] See some examples. Figure 3 and Figure 4 The fixing end 31 consists of symmetrically arranged fixing ears on opposite sides of the connector housing. The fixing end 31 has fixing holes 311 through which screws fix the connector housing to the middle frame 5 of the electronic device 100. For details, please refer to... Figure 4 The small board support 1 is provided with a connecting hole 12. Screws pass through the connecting hole 12 on the board support and the fixing hole 311 on the fixing end 31 in sequence to connect with the middle frame 5 of the electronic device 100. Please refer to Figure 4 Small plate bracket 1 and fixed end 31 along Figure 4 The Z-axis direction is set sequentially, that is, the small board bracket 1 and the electrical connector module 3 are set sequentially along the thickness direction of the electronic device 100.

[0092] In some examples, electrical connector module 3 is only electrically connected to the motherboard; in other examples, please refer to [link to relevant documentation]. Figure 4 The electronic device 100 also includes a flexible circuit board 6, and the flexible circuit board 6 and the motherboard are both connected to the electrical connector module 3.

[0093] In this embodiment, the electronic device 100 can be charged using a fast charging method, that is, by increasing the output voltage and current of the charger, the charging power is increased, thereby shortening the charging time. Specifically, there are several methods: by increasing the output voltage of the charger, more energy can be input to the battery in the same amount of time; or, by increasing the output current of the charger, more energy can be input to the battery in the same amount of time; or, both voltage and current can be increased simultaneously.

[0094] In scenarios where electronic device 100 can be fast-charged, the electrical connector module 3 needs to be able to withstand higher currents, meaning it needs to meet certain current-carrying capacity requirements. One implementation involves adding a grounding point to the electrical connector module 3 to meet the current-carrying capacity requirements of fast-charging scenarios. Adding a grounding point reduces the impedance of the grounding path, allowing current to flow more smoothly under the same voltage, thereby improving the current-carrying capacity.

[0095] In one example, the small board bracket 1 can be electrically connected to the electrical connector module 3, and the connection between the two forms the grounding point of the electrical connector module 3.

[0096] Please see Figure 5 The diagram illustrates a portion of the structure of the small board bracket 1. To achieve electrical connection between the small board bracket 1 and the electrical connector module 3, a spring contact 8 can be soldered to the side of the small board bracket 1 facing the electrical connector module 3. The spring contact 8 directly or indirectly contacts the electrical connector module 3, thus achieving electrical connection between the small board bracket 1 and the electrical connector module 3. However, soldering the spring contact 8 to the side of the small board bracket 1 facing the electrical connector module 3 is not conducive to the thinning design of the electronic device 100. For details, please refer to... Figure 6 The diagram illustrates a cross-sectional view of the small board support 1 and the spring contact 8. Since the spring contact 8 needs to be installed on the side of the small board support 1 facing the electrical connector module 3, a recessed clearance groove 16 needs to be formed on the small board support 1, extending away from the electrical connector module 3. The distance between the clearance groove 16 and the electrical connector module 3 needs to take into account the required installation height of the spring contact 8. The presence of the clearance groove 16 increases the height of the small board support 1 along the thickness direction of the electronic device 100, which is detrimental to the thinning design of the electronic device 100. Furthermore, the spring contact 8 is typically fixed to the small board support 1 by soldering. Therefore, if the spring contact 8 is soldered to the small board support 1, the distance between the clearance groove 16 and the electrical connector module 3 also needs to take into account the height allowance required for soldering the spring contact 8. Please refer to [link to relevant documentation]. Figure 6 The diagram illustrates the welding layer 9 between the spring piece 8 and the small plate support 1. Figure 6 The diagram illustrates that the clearance groove 16 protrudes along the Z-axis direction, that is, along the Z-axis direction of the electronic device 100.

[0097] In addition, due to the thickness of the electronic device 100, in some scenarios, it is not possible to achieve electrical connection between the small board bracket 1 and the electrical connector module 3 by welding a spring piece 8 on the side of the small board bracket 1 facing the electrical connector module 3.

[0098] Please see Figure 7 In this embodiment, an opening 11 is provided on the small board support 1, and the elastic plate structure 2 is connected to the hole wall of the opening 11. That is, the elastic plate structure 2 is fixed on the hole wall of the opening 11. The elastic plate structure 2 undergoes elastic deformation and is electrically connected to the electrical connector module 3 to form the grounding point of the electrical connector module 3.

[0099] Specifically, the elastic plate structure 2 is in direct or indirect contact with the electrical connector module 3.

[0100] In one example, a small plate support 1 has one opening 11; in another example, the small plate support 1 has two or more openings 11, and an elastic plate structure 2 is connected to the wall of each opening 11.

[0101] Please see Figure 6 In the Z-axis direction, i.e., the thickness direction of the electronic device 100, there are two layers of plates: the small board support 1 and the spring piece 8. Figure 7 In the example, by setting the elastic plate structure 2 to be connected to the hole wall of the opening 11, the superposition of the small board support 1 and the spring piece 8 in the thickness direction of the electronic device 100 can be avoided, as well as the influence of the thickness of the welding between the small board support 1 and the spring piece 8 on the thickness of the electronic device 100 can be avoided.

[0102] In this embodiment, by providing an opening 11 on the small board support 1 and connecting the elastic plate structure 2 to the wall of the opening 11, the small board support 1 and the electrical connector module 3 can be electrically connected, while minimizing the space occupied in the thickness direction of the electronic device 100 due to the introduction of the elastic plate structure 2, so as to facilitate the thinning design of the electronic device 100.

[0103] Regarding the connection between the elastic plate structure 2 and the small plate bracket 1, in one embodiment, the elastic plate structure 2 and the small plate bracket 1 are integrally formed; in another embodiment, when the thickness of the elastic plate structure 2 and the small plate bracket 1 meets the welding conditions, the elastic plate structure 2 can be welded to the hole wall of the small plate bracket 1 by welding; in another embodiment, when the bonding conditions are met and the connection strength between the elastic plate structure 2 and the small plate bracket 1 after bonding meets the usage requirements, the elastic plate structure 2 can be glued to the hole wall of the small plate bracket 1 by adhesive.

[0104] The elastic plate structure 2 and the small plate support 1 are integrally formed. In a specific example, the elastic plate structure 2 can be directly stamped onto the small plate support 1. The stamping process is simple, precise, and produces a good product surface quality. In addition, since the elastic plate structure 2 and the small plate support 1 are integrally stamped, the connection between the elastic plate structure 2 and the small plate support 1 has high strength.

[0105] In a specific example, the elastic plate structure 2 is directly stamped on the small plate support 1, and the thickness of the small plate support 1 is in the range of 0.15mm.

[0106] In this embodiment, the elastic plate structure 2 and the small plate bracket 1 are integrally formed, which not only helps to reduce the space occupied in the thickness direction of the electronic device 100 due to the introduction of the elastic plate structure 2, but also allows for more flexible and diverse design of the elastic plate structure 2.

[0107] In one embodiment, the elastic plate structure 2 directly contacts the electrical connector module 3 to achieve electrical connection, thereby forming a grounding point for the electrical connector module 3; in another embodiment, the electrical connector module 3 is electrically connected to the elastic plate structure 2 through a circuit board, and the elastic plate structure 2 and the electrical connector module 3 are indirectly contacted to achieve electrical connection, thereby forming a grounding point for the electrical connector module 3.

[0108] When the elastic plate structure 2 is in direct contact with the electrical connector module 3, the elastic plate structure 2 can be configured to abut against the connector housing of the electrical connector module 3.

[0109] When the electrical connector module 3 is electrically connected to the elastic plate structure 2 via the circuit board, preferably, please refer to... Figure 8 A flexible circuit board 6 is also provided between the bracket board 4 and the electrical connector module 3. The flexible circuit board 6 is electrically connected to the electrical connector module 3. The elastic plate structure 2 undergoes elastic deformation and comes into contact with the flexible circuit board 6, thereby achieving indirect contact between the elastic plate structure 2 and the electrical connector module 3.

[0110] The flexible circuit board 6 is a printed circuit board made of a flexible insulating substrate. It is flexible, can be bent, folded, and rolled, and can adapt to various complex spatial shapes and dynamic usage environments. The connection between the electrical connector module 3 and the flexible circuit board 6 can be achieved by soldering or bonding with conductive adhesive.

[0111] Depending on the structural components within the electronic device 100, if the electronic device 100 does not have a flexible circuit board 6 connected to the electrical connector module 3, the elastic plate structure 2 can be directly in contact with the electrical connector module 3. If the electronic device 100 has a flexible circuit board 6 connected to the electrical connector module 3, a portion of the flexible circuit board 6 can be positioned between the support plate 4 and the electrical connector module 3, thus enabling the elastic plate structure 2 to be electrically connected to the electrical connector module 3 via the flexible circuit board 6. In other words, the connection method between the elastic plate structure 2 and the electrical connector module 3 is not limited to one method.

[0112] In one embodiment, a flexible circuit board 6 is disposed between the support plate 4 and the electrical connector module 3, and the electronic device 100 further includes a reinforcing piece 7. The reinforcing piece 7 and the electrical connector module 3 are disposed on both sides of the flexible circuit board 6. The reinforcing piece 7 is electrically connected to the flexible circuit board 6, and the elastic plate structure 2 abuts against the reinforcing piece 7. Please refer to [link to relevant documentation]. Figure 8 and Figure 9 The diagram illustrates the reinforcing sheet 7 positioned between the flexible circuit board 6 and the elastic plate structure 2.

[0113] The reinforcing sheet 7 enhances the rigidity and strength of the flexible circuit board 6, improving its reliability and durability. In this embodiment, the reinforcing sheet 7 needs to be made of a conductive material; for example, it can be stainless steel or aluminum foil.

[0114] The reinforcing plate 7 is electrically connected to the flexible circuit board 6. For example, the reinforcing plate 7 and the flexible circuit board 6 are electrically connected using conductive adhesive. Conductive adhesive is a special adhesive containing a large number of conductive fillers, such as metal powder, metal fibers, or conductive particles. When current passes through the conductive adhesive, electrons flow between the fillers, thereby achieving conductivity. The elastic plate structure 2 undergoes elastic deformation and comes into contact with the reinforcing plate 7 to form the grounding point of the electrical connector module 3.

[0115] In this embodiment, by providing a reinforcing sheet 7 on the flexible circuit board 6, the reliability and durability of the flexible circuit board 6 are improved, and the flexible circuit board 6 is easily damaged when the elastic plate structure 2 directly abuts against it.

[0116] In one embodiment, please refer to Figure 9A first mating area 13 is formed on the small plate support 1, and an opening 11 is provided in the first mating area 13. The area on the small plate support 1 located around the first mating area 13 is called the second mating area 14, and the second mating area 14 is connected to the first mating area 13.

[0117] The side of the first mating area 13 facing away from the electrical connector module 3 is the upper side 131 of the first mating area, and the side of the first mating area 13 facing the electrical connector module 3 is the lower side 132 of the first mating area. The side of the second mating area 14 facing away from the electrical connector module 3 is the upper side 141 of the second mating area, and the side of the second mating area 14 facing the electrical connector module 3 is the lower side 142 of the second mating area.

[0118] Please see Figure 9 Along the Z-axis direction in the figure, that is, along the thickness direction of the electronic device 100, the first mating area 13 is directly opposite the electrical connector module 3; in the example where the elastic plate structure 2 abuts against the reinforcing piece 7, the first mating area 13 is directly opposite the reinforcing piece 7.

[0119] In one example, the first mating region 13 is directly opposite the central region of the reinforcing piece 7. That is, the area of ​​the reinforcing piece 7 in the XY plane is larger than the area of ​​the first mating region 13 in the XY plane, and the first mating region 13 is located relatively in the middle of the reinforcing piece 7.

[0120] In one example, see Figure 9 A third mating area 15 is formed on the small board support 1. The third mating area 15 is located outside the second mating area 14. The second mating area 14 is recessed relative to the third mating area towards the electrical connector module 3.

[0121] The small board bracket 1 is connected to the housing of the electronic device 100, such as the middle frame 5, to fix components such as the small board 4, flexible circuit board 6, and electrical connector module 3. The shape of the small board bracket 1 needs to match the shape and distribution of components such as the small board 4, flexible circuit board 6, and electrical connector module 3.

[0122] In one embodiment, the upper side 131 of the first mating region and the upper side 141 of the second mating region are on the same horizontal plane. Preferably, the lower side 132 of the first mating region and the lower side 142 of the second mating region are on the same horizontal plane.

Figure 7 The dashed square line is used as the boundary between the first mating region 13 and the second mating region 14.

[0124] Please see Figure 10 (a) in the diagram is a cross-sectional view of the small plate support 1 and the elastic plate structure 2. Figure 10 Figure (a) shows that the upper side 131 of the first mating region and the upper side 141 of the second mating region are on the same horizontal plane, and the lower side 132 of the first mating region and the lower side 142 of the second mating region are on the same horizontal plane.

The thickness of the small board bracket 1 is b, and the thickness of the elastic plate structure 2 is equal to the thickness of the small board bracket 1, which is b.

Please refer to [link to relevant documentation]. Figure 10 The straight dashed line indicates that the end of the spring piece 8 is flush with the end of the elastic plate structure 2, so that when the spring piece 8 and the elastic plate structure 2 come into contact with the reinforcing piece 7, the deformation of the two is the same.

[0128] Please see Figure 10 In (a), the upper side surface 131 of the first mating area and the upper side surface 141 of the second mating area are on the same horizontal plane. Please refer to [link / reference]. Figure 10 In (b), the height of the protrusion of the groove on the opposite surface 151 is H1 = b + c.

[0129] exist Figure 10In (b), in order to reserve space for the installation of the spring piece 8, it is necessary to punch a relief groove 16 on the small board bracket 1, which increases the space occupied by the small board bracket 1 in the thickness direction of the electronic device 100. In this embodiment, it is not necessary to punch a relief groove 16 on the small board bracket 1. Since the upper side 131 of the first mating area and the upper side 141 of the second mating area are on the same horizontal plane, the addition of the elastic plate structure 2 on the small board bracket 1 does not increase the space occupied in the thickness direction of the electronic device 100.

[0130] In one embodiment, the first mating region 13 is recessed relative to the second mating region 14 in a direction away from the electrical connector module 3. See also... Figure 11 In (a), a cross-sectional schematic diagram of the small plate support 1 and the elastic plate structure 2 is shown.

Please refer to [link to relevant documentation]. Figure 11 The straight dashed line indicates that the end of the spring piece 8 is flush with the end of the elastic plate structure 2, so that when the spring piece 8 and the elastic plate structure 2 come into contact with the reinforcing piece 7, the deformation of the two is the same.

[0134] See comparison Figure 11In Figures (a) and (b), the difference between the height H1 of the groove protrusion on the opposite surface 151 and the height H2 of the upper side surface 131 of the first mating area is b+c.

[0135] In this embodiment, although the first mating region 13 is recessed away from the electrical connector module 3 relative to the second mating region 14, the small board support 1 and the spring piece 8 are avoided from overlapping in the thickness direction of the electronic device 100 by setting the elastic plate structure 2 to connect with the hole wall of the opening 11. While realizing the electrical connection between the small board support 1 and the electrical connector module 3, the space occupied in the thickness direction of the electronic device 100 caused by the introduction of the elastic plate structure 2 can be minimized.

[0136] In one embodiment, the first mating region 13 is recessed relative to the second mating region 14 in a direction away from the electrical connector module 3, and the height difference between the upper side surface 131 of the first mating region and the upper side surface 141 of the second mating region is not greater than the thickness of the elastic plate structure 2. Please refer to [link to relevant documentation]. Figure 12 (a) in the diagram is a cross-sectional view of the small plate support 1 and the elastic plate structure 2.

[0140] exist Figure 12 In this context, the distance d from the end of the spring piece 8 furthest from the small plate support 1 to the small plate support 1 is set to be equal to the distance d from the free end 211 of the elastic plate structure 2 to the lower side 142 of the second mating area. Please refer to [link to relevant documentation]. Figure 12A straight, dashed line indicates that the end of the spring piece 8 is flush with the end of the elastic plate structure 2. The installation height of the elastic plate structure 2 is set to a2, which is greater than the installation height of the spring piece 8, a1. Please refer to... Figure 12 In (a), the lower side surface 132 of the first mating area and the lower side surface 142 of the second mating area have a height difference H2 that is less than b. Please refer to [reference needed]. Figure 10 In (b), the height of the protrusion of the groove on the opposite surface 151 is H1 = b + c.

[0141] To provide space for the installation of the spring contact 8, a clearance groove 16 needs to be stamped on the small board bracket 1. The height of the clearance groove 16 in the thickness direction of the electronic device 100 is not less than the thickness of the spring contact 8 and the welding thickness between the spring contact 8 and the small board bracket 1. In this embodiment, the distance H2 from the upper side 131 of the first mating area to the upper side 141 of the second mating area is less than the thickness of the elastic plate structure 2. Therefore, this embodiment can reduce the space occupied in the thickness direction of the electronic device 100. In addition, since the installation height of the elastic plate structure 2 is greater than the installation height of the spring contact 8, the elasticity performance of the elastic plate structure 2 is better than that of the spring contact 8. Therefore, in this embodiment, not only can the space occupied in the thickness direction of the electronic device 100 be reduced, but it also facilitates a stable electrical connection between the elastic plate structure 2 and the electrical connector module 3.

[0142] Regarding the elastic plate structure 2, in one embodiment, the elastic plate structure 2 includes one or more elastic arms 21, which extend at an angle toward the electrical connector module 3.

[0143] The elastic arm 21 includes a free end 211. When the free end 211 of the elastic arm 21 comes into contact with the electrical connector module 3, the flexible circuit board 6, or the reinforcing piece 7, the elastic arm 21 can undergo elastic deformation.

[0144] The elastic plate structure 2 includes one or more elastic arms 21, i.e., the number of elastic arms 21 can be one, two, three, four, etc. When there are two or more elastic arms 21, each elastic arm 21 undergoes elastic deformation and electrically connects to the electrical connector module 3. Each elastic arm 21 and the electrical connector module 3 electrically connect to form a grounding point of the electrical connector module 3. Please refer to [link / reference]. Figures 13-14 , Figure 13 This is a schematic diagram of the small plate support 1 and the elastic arm 21 provided in this embodiment. Figure 14 for Figure 13 A magnified view of a portion of point A in the middle. Figure 13 and Figure 14 The diagram illustrates two elastic arms 21. The elastic plate structure 2 can be configured to include an appropriate number of elastic arms 21 as needed.

[0145] In this embodiment, when there are multiple elastic arms 21, multiple grounding points of the electrical connector module 3 can be formed between the elastic plate structure 2 and the electrical connector module 3, which can further improve the current carrying capacity.

[0146] In one embodiment, please refer to Figure 14 From the direction away from the free end 211 of the elastic arm 21 to the direction closer to the free end 211 of the elastic arm 21, the cross-sectional area of ​​the elastic arm 21 is the same, that is, the elastic arm 21 is in the shape of a rectangular plate.

[0147] In one embodiment, the cross-sectional area of ​​the elastic arm 21 decreases from the direction away from the free end 211 of the elastic arm 21 to the direction closer to the free end 211 of the elastic arm 21.

[0148] For example, the cross-sectional area of ​​the elastic arm 21 gradually decreases from the direction away from the free end 211 of the elastic arm 21 to the direction closer to the free end 211 of the elastic arm 21. For example, the elastic arm 21 is generally triangular or trapezoidal in shape.

[0149] For example, the free end 211 of the elastic arm 21 is a pointed end and the free end 211 of the elastic arm 21 is rounded.

[0150] For example, from the direction away from the free end 211 of the elastic arm 21 to the direction closer to the free end 211 of the elastic arm 21, the cross-sectional area of ​​a portion of the elastic arm 21 gradually decreases. For instance, the elastic arm 21 includes a first segment and a second segment, the first segment is connected to the second segment, and the end of the second segment away from the first segment forms the free end 211 of the elastic arm 21. From the direction away from the free end 211 of the elastic arm 21 to the direction closer to the free end 211 of the elastic arm 21, the cross-sectional area of ​​the first segment remains unchanged, while the cross-sectional area of ​​the second segment... The area gradually decreases, or the cross-sectional area of ​​the first segment gradually decreases while the cross-sectional area of ​​the second segment remains unchanged; or, the elastic arm 21 includes a first segment, a second segment, and a third segment, the first segment, the second segment, and the third segment are connected sequentially, and the end of the third segment away from the second segment forms the free end 211 of the elastic arm 21. From the direction away from the free end 211 of the elastic arm 21 to the direction close to the free end 211 of the elastic arm 21, the cross-sectional areas of the first segment and the third segment remain unchanged while the cross-sectional area of ​​the second segment gradually decreases.

[0151] One end of the elastic arm 21 is the free end 211, and the connecting end of the elastic arm 21 is opposite to the free end 211. In this embodiment, since the cross-sectional area of ​​the elastic arm 21 decreases from the direction away from the free end 211 to the direction closer to the free end 211, the cross-sectional area of ​​the elastic arm 21 is the largest at the connecting end, which is beneficial to the stable connection of the elastic arm 21. As the cross-sectional area of ​​the elastic arm 21 decreases towards the free end 211, it is beneficial to allow the elastic arms 21 to avoid each other when the elastic plate structure 2 includes multiple elastic arms 21.

[0152] In one embodiment, the elastic arm 21 directly abuts against the electrical connector module 3, the flexible circuit board 6, or the reinforcing sheet 7; or, in one embodiment, the elastic arm 21 is provided with a contact protrusion 23, the contact protrusion 23 being close to the free end 211 of the elastic arm 21 and facing the electrical connector module 3. Please refer to [link to relevant documentation]. Figures 15-16 , Figure 15 This is a schematic diagram of the small plate support 1 and the elastic arm 21 provided in this embodiment. Figure 16 for Figure 15 A magnified view of a section at point B. Figure 16 The diagram illustrates the contact protrusion 23. The contact protrusion 23 is used to abut against the electrical connector module 3, the flexible circuit board 6, or the reinforcing piece 7.

[0153] Preferably, the outer surface of the contact protrusion 23 is spherical.

[0154] Preferably, the elastic arm 21 and the contact protrusion 23 are integrally formed.

[0155] When there are two or more elastic arms 21, each elastic arm 21 is provided with a contact protrusion 23, or some elastic arms 21 are provided with contact protrusions 23.

[0156] In this embodiment, a contact protrusion 23 is provided on the elastic arm 21 to facilitate better electrical connection between the elastic plate structure 2 and the electrical connector module 3.

[0157] In one embodiment, please refer to Figure 14 and Figure 16 The elastic arm 21 is connected to the wall of the opening 11.

[0158] For example, the shape of the opening 11 is circular or polygonal, and preferably, the shape of the opening 11 is square or rectangular.

[0159] For example, the opening 11 is rectangular in shape; please refer to [link / reference]. Figure 17 and Figure 18This is a front view schematic diagram of the elastic arm 21 connected to the wall of the opening 11. The opening 11 includes a first hole wall 111, a second hole wall 112, a third hole wall 113, and a fourth hole wall 114. The first hole wall 111 and the third hole wall 113 are arranged opposite to each other, and the second hole wall 112 and the fourth hole wall 114 are arranged opposite to each other. At least one of the first hole wall 111, the second hole wall 112, the third hole wall 113, and the fourth hole wall 114 is provided with an elastic arm 21.

[0160] For example, when the opening 11 is rectangular, since the elastic arm 21 is generally strip-shaped, to ensure a reasonable layout and make full use of the space of the opening 11, it is preferable to provide an elastic arm 21 on each of the two opposite walls of the opening 11. Please refer to [link to relevant documentation]. Figure 17 and Figure 18 The diagram shows that an elastic arm 21 is provided on each of the two opposite holes of the opening 11.

[0161] For example, please see Figure 17 The first hole wall 111 and the third hole wall 113 of the opening 11 are the short sides of the opening 11. An elastic arm 21 is provided on the first hole wall 111 and the third hole wall 113 respectively. Preferably, the elastic arm 21 is triangular in shape.

[0162] For example, please see Figure 18 The second hole wall 112 and the fourth hole wall 114 of the opening 11 are the long sides of the opening 11. An elastic arm 21 is provided on the second hole wall 112 and the fourth hole wall 114 respectively. Preferably, the elastic arm 21 is triangular in shape.

[0163] Preferably, please refer to Figure 17 and Figure 18 The opening 11 is divided into two spaces along the diagonal. Figure 17 and Figure 18 The diagonals are represented by dashed lines, and the elastic arms 21 of the two triangles are located in the space on both sides of the diagonals.

[0164] Preferably, the two elastic arms 21 are the first elastic arm and the second elastic arm, respectively. See [link to relevant documentation]. Figure 17 ,exist Figure 17 The first elastic arm is located on the left, and the second elastic arm is located on the right. The side of the first elastic arm closest to the fourth hole wall 114 is parallel to the fourth hole wall 114, and the side of the first elastic arm away from the fourth hole wall 114 is parallel to the diagonal of the opening 11. The side of the second elastic arm closest to the second hole wall 112 is parallel to the second hole wall 112, and the side of the second elastic arm away from the second hole wall 112 is parallel to the diagonal of the opening 11.

[0165] For example, the small plate support 1 is provided with two or more openings 11, and the number of elastic arms 21 in each opening 11 may be the same or different.

[0166] In this embodiment, by connecting the elastic arm 21 to the hole wall of the opening 11, the structure of the elastic plate structure 2 is simplified, and it is also beneficial to increase the length of the elastic arm 21.

[0167] Regarding the elastic plate structure 2, in one embodiment, please refer to... Figure 18 The elastic plate structure 2 also includes a connecting plate 22, which is connected to the wall of the opening 11, and the elastic arm 21 is disposed on the connecting plate 22.

[0168] In this embodiment, the elastic arm 21 is not directly connected to the wall of the opening 11, but is indirectly connected to the wall of the opening 11 through the connecting plate 22. That is, the connecting end of the elastic arm 21 is formed between the elastic arm 21 and the connecting plate 22.

[0169] For example, the shape of the opening 11 is circular or polygonal, and preferably, the shape of the opening 11 is square or rectangular.

[0170] For example, please see Figure 19 Both ends of the connecting plate 22 are connected to the wall of the opening 11.

[0171] For example, please see Figure 20 One end of the connecting plate 22 is connected to the wall of the opening 11.

[0172] Preferably, one or more elastic arms 21 are provided on the connecting plate 22, such as one, two, three or four elastic arms 21.

[0173] For example, the small plate support 1 is provided with two or more openings 11, and each opening 11 is connected to a connecting plate 22 on its hole wall. The number of elastic arms 21 on each connecting plate 22 may be the same or different.

[0174] For example, the two ends of the connecting plate 22 are respectively connected to the two hole walls opposite to the opening 11.

[0175] For example, please see Figure 18 The two ends of the connecting plate 22 are respectively connected to the two hole walls opposite to the opening 11. There are two elastic arms 21, which are respectively set on opposite sides of the connecting plate 22.

[0176] Preferably, please refer to Figure 19 Two elastic arms 21 are symmetrically arranged on opposite sides of the connecting plate 22.

[0177] In this embodiment, by using an elastic arm 21 connected to the hole wall of the opening 11 via a connecting plate 22, other forms of the elastic plate structure 2 are provided.

[0178] In one embodiment, the small plate support 1 is provided with two or more openings 11. In some openings 11, the elastic arm 21 is directly connected to the hole wall of the opening 11, and in some openings 11, the elastic arm 21 is connected to the hole wall of the opening 11 through the connecting plate 22.

[0179] In one embodiment, in the thickness direction of the small board support 1, the side of the elastic plate structure 2 facing away from the electrical connector module 3 does not protrude from the board surface of the small board support 1 around the opening 11, that is, the side of the elastic plate structure 2 facing away from the electrical connector module 3 does not protrude from the upper side 131 of the first mating area.

[0180] In this embodiment, the side of the elastic plate structure 2 that is away from the electrical connector module 3 does not protrude from the upper side 131 of the first mating area. This means that when the elastic plate structure 2 is in its natural state, that is, when no elastic deformation occurs, the side of the elastic plate structure 2 that is away from the electrical connector module 3 does not protrude from the upper side 131 of the first mating area.

[0181] Preferably, when the elastic plate structure 2 is in elastic deformation, the side of the elastic plate structure 2 away from the electrical connector module 3 still does not protrude from the upper side 131 of the first mating area.

[0182] Specifically, when the elastic arm 21 of the elastic plate structure 2 is directly connected to the wall of the opening 11, please refer to... Figure 14 When the elastic arm 21 is in its natural state (i.e., the elastic arm 21 is not in contact with the electrical connector module 3, the flexible circuit board 6, or the reinforcing piece 7, and the elastic arm 21 is not in an elastically deformed state), the side of the elastic arm 21 facing away from the electrical connector module 3 does not protrude from the upper side 131 of the first mating area. When the elastic arm 21 is in an elastically deformed state, it will elastically deform in the direction away from the electrical connector module 3. In this case, preferably, the side of the elastic arm 21 facing away from the electrical connector module 3 does not still protrude from the upper side 131 of the first mating area.

[0183] Specifically, when the elastic arm 21 of the elastic plate structure 2 is connected to the hole wall of the opening 11 through the connecting plate 22, when the elastic arm 21 is in its natural state, neither the side of the connecting plate 22 away from the electrical connector module 3 nor the side of the elastic arm 21 away from the electrical connector module 3 protrudes from the upper side 131 of the first mating area; when the elastic arm 21 is in an elastically deformed state, preferably the side of the elastic arm 21 away from the electrical connector module 3 still does not protrude from the upper side 131 of the first mating area.

[0184] In this embodiment, by setting the side of the elastic plate structure 2 away from the electrical connector module 3 to not protrude from the small board bracket 1 around the opening 11, the space occupied in the thickness direction of the electronic device 100 is avoided by the side of the elastic plate structure 2 away from the electrical connector module 3 protruding from the small board bracket 1 around the opening 11.

[0185] Regarding the shape of the elastic arm 21, in one embodiment, the elastic arm 21 includes a connecting section 212, which is connected to the small board support 1 or the connecting plate 22. Along the direction of the elastic arm 21 from the connecting end to the free end 211, the connecting section 212 bends towards the electrical connector module 3. See also... Figure 21 This illustrates that the elastic arm 21 is connected to the wall of the hole 11 on the small plate support 1. Figure 21 In the diagram, the elastic arm 21 is divided into connecting sections 212 by a dashed line L1. It should be noted that... Figure 21 The dashed line L1 shown is for illustrative purposes only and does not impose any restrictions on the connecting section 212. For example... Figure 21 As shown, the connecting section 212 bends downward along the direction of the elastic arm 21 from the connecting end to the free end 211.

[0186] Please see Figure 22 Assuming the connecting section 212 is flat, when the elastic arm 21 is in an elastic deformation state ( Figure 22 The dashed line in the middle indicates the elastic deformation state of the elastic arm 21. At this time, the side of the elastic arm 21 away from the electrical connector module 3 may protrude from the upper side 131 of the first mating area.
