Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of communication devices, in particular to an electronic device. BACKGROUND

[0002] At present, with the development of electronic technology, more and more components are configured in electronic devices, and the functions that can be realized are also more and more rich. Electronic devices such as mobile terminals and wearable devices are more and more closely related to the work and life of users due to their rich functions. The rich functions of electronic devices are supported by various components, such as circuit boards, connectors, antenna modules, and the like, which are essential devices of electronic devices. In recent years, with the development of mobile communication devices, the number of antenna frequency bands is also increasing, and there are a large number of high-speed data lines in some components in electronic devices. While these high-speed data lines transmit data, a large number of high-frequency interference signals also exist. The existence of these high-frequency interferences will affect the receiving sensitivity of electronic devices in the working frequency band.

[0003] To avoid the interference of electromagnetic signals on antenna signals, or the interference of antenna signals on the signals of some devices inside the electronic device, a shield cover is usually provided in the electronic device when the electronic device is manufactured, and the shield cover is used to isolate some devices inside the electronic device from the antenna. An electrical connector is provided inside the electronic device, for example, an FPCB (Flexible Printed Circuit Board, FPCB for short) connector, which can be used to transmit signals from one end to the other end to achieve the purpose of signal transmission. The existing FPCB connector needs to ensure the stability of signal connection and prevent electromagnetic interference due to high-speed data transmission. At present, the measure taken to avoid the interference of the FPCB connector with the antenna signal is usually to wrap the FPCB connector with a mainboard SMT (Surface Mount Technology, SMT for short) hardware part to play a shielding role. However, the existing scheme of providing a shield cover outside the FPCB connector to shield the interference of the antenna signal has the following disadvantages: when the FPCB connector is disassembled, the shield cover needs to be disassembled first, which is easy to warp and deform. After being buckled again, the problem of unreliable contact of the shield cover may occur, which cannot effectively prevent interference.

[0004] With the increasing shielding requirements of the internal devices of electronic devices on antenna signals, it is necessary to adopt a more optimal design scheme to simultaneously meet the reliability of the shielding function and the disassembly and assembly in a limited structural space. SUMMARY

[0005] The electronic device provided in the present application can solve the problems in the prior art or at least partially solve the above technical problems.

[0006] According to a first aspect of the present application, an electronic device is provided, comprising a first circuit board, at least one electronic component, and a bracket assembly; the bracket assembly comprises a bracket and a metal piece, the metal piece is arranged on the bracket, and the metal piece is provided with a metal terminal; the at least one electronic component is arranged on the first circuit board; the first circuit board further comprises an electrical contact area, which is connected with a grounding part of the first circuit board; the metal terminal is connected with the electrical contact area; at least part of the bracket assembly is arranged above the electronic component; and the metal terminal and at least part of the metal piece at least partially surround the at least one electronic component.

[0007] In the electronic device, by integrating the metal piece onto the bracket, integrating the metal terminal onto the metal piece, and vertically pressing the metal terminal to the electrical contact area of the first circuit board, a grounding shield can be formed, and the metal terminal and at least part of the metal piece at least partially surround (enclose) the electronic component, which can effectively prevent electromagnetic interference, thereby playing a shielding effect on the electronic component and ensuring the stability of signal transmission. The structure is simple and convenient to disassemble, can achieve the effect that repeatedly disassembling the electronic component (such as an electrical connector) does not affect the shielding performance, ensures the reliability of the shielding function, and saves the vertical space. It should be noted that the metal terminal and at least part of the metal piece at least partially surround the at least one electronic component means that the metal terminal and at least part of the metal piece can completely surround or enclose the outside of the electronic component, i.e., surround all sides of the electronic component, or partially surround or enclose the outside of the electronic component, i.e., surround one side, two sides, or three sides of the electronic component, and the surrounded side needs to be close to the position of the antenna area, so as to isolate the electronic component from the antenna by the metal terminal and the metal piece. Preferably, the metal terminal and the metal piece surround all sides of the electronic component, thereby increasing the shielding effect.

[0008] It should be noted that the electrical contact area on the circuit board can be an area where the circuit board is electrically connected with other metal components (such as a metal plate). The electrical contact area on the circuit board can also be referred to as an electrical contact position, and the electrical contact area can be a metal area exposed by the circuit board. For example, the electrical contact area can be a copper-exposed area of the circuit board.

[0009] It should be noted that in the embodiments of the present application, the metal piece can be a metal sheet, and the metal terminal can be a grounding spring piece.

[0010] In a possible implementation, the metal terminal is elastically connected with the electric contact area; or, the metal terminal is welded with the electric contact area.

[0014] In a possible implementation, the metal member includes a metal member body and a bent portion, the bent portion is arranged at an end of the metal member body, and the metal terminal is fixed to the metal member body.

[0015] To improve the shielding effect, the metal member can be bent to form a bent portion. For example, any two ends, three ends, or more ends of the metal member can be bent to form a bent portion, and the electronic device can be located between the bent portions, that is, at least part of the side surface of the electronic device can be covered by the bent portion, and the shielding effect is further improved.

[0016] The metal terminal can be arranged at one end or more ends of the metal member body, and the remaining end of the metal member can be bent to form a bent portion, so that omnidirectional shielding can be achieved, and the shielding effect is further improved.

In other embodiments, the first metal terminal and the second metal terminal can be arranged, the first metal terminal can be arranged along the first direction of the metal piece, the second metal terminal can be arranged along the second direction of the metal piece, and the second direction of the metal piece is not bent, i.e., the second metal terminal is directly fixed to the second direction of the metal piece. In other embodiments, the first metal terminal and the second metal terminal can be arranged, the first metal terminal can be arranged along the first direction of the metal piece, the second metal terminal can be arranged along the second direction of the metal piece, and the second direction of the metal piece is bent to form a bending portion, i.e., the second metal terminal is fixed to the bottom end of the bending portion.

[0022] In one possible implementation, the metal terminal includes at least one spring leg, the root of the spring leg is arranged integrally with the metal terminal, and the other end of the spring leg is a free end.

[0023] It should be understood that the metal terminal can be a contact spring with elasticity, and the metal terminal can be spring-connected or welded with the electrical contact position of the circuit board, which can play a grounding function and shield electromagnetic interference.

The metal terminal can be provided with one, two or more spring legs, and the plurality of spring legs can be arranged at equal intervals along the length direction of the metal terminal. It should be understood that the number of spring legs can correspond to the exposed copper connection area on the circuit board.

By adding the metal piece, the strength of the bracket can be enhanced, the rigidity of the bracket can be improved, and the metal shielding effect can also be achieved.

[0036] In a possible implementation, the metal terminal is made of steel; for example, the metal terminal can be made of stainless steel.

[0047] At least part of the housing serves as an antenna, the metal terminal and at least part of the metal member at least partially surround the at least one electronic component, and the metal terminal and at least part of the metal member isolate the electronic component and the antenna.

[0093] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0094] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0095] Unless otherwise defined or stated, the technical and scientific terms used in this document have the same meaning as those familiar to a person skilled in the art.

[0096] Those skilled in the art will understand that, as described in the background section, traditional shielding solutions for electrical connectors and antenna signal interference are limited by the reliability of the shielding function and the reliability of installation / removal, and thus cannot meet the requirements. Taking the FPCB connector as an example, this paper details existing shielding solutions for connector and antenna signal interference. It should be understood that other related connectors or similar electronic devices also have the same or similar problems.

[0097] like Figures 1 to 3 The diagram shows a shielding structure for an existing FPCB connector. The electrical connector 6, an FPCB connector, is enclosed by a metal shielding frame 10, thus achieving a shielding effect. Further, a metal shielding frame 10 is first SMT-mounted around the FPCB connector, and then a shielding cover 11 is fastened to the metal shielding frame 10, thus achieving a shielding effect. However, this solution has a drawback: disassembling the FPCB connector requires first removing the metal shielding frame 10 and the shielding cover 11. Due to the material limitations of the shielding frame and cover, they are prone to warping and deformation during disassembly. This can easily lead to problems such as failure or unreliable contact during reinstallation, resulting in gaps at the connection points. Electromagnetic interference signals can leak through these gaps, reducing the shielding effect of the shielding frame and cover.

[0098] Therefore, in order to overcome the imperfections of the prior art, the technical solution of this application provides an electronic device that can take into account the advantages of superior shielding effect and reliable detachable performance of electronic devices (electrical connectors).

[0099] In one specific embodiment, the present application will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0100] Please refer to the attached document. Figures 4-18Embodiments of the present application provide an electronic device, which can be a terminal device with an antenna and an electrical connector.

[0101] It can be understood that the electronic device can be an electronic device with wireless signal transmitting / receiving function. The antenna 2 can be used to realize the transmitting / receiving of wireless signals; the electrical connector 6 can be used to transmit electrical signals from one end to the other end to achieve the purpose of signal transmission. For example, the electrical connector 6 can be used to transmit electrical signals between the camera and the processor, and can also be used to transmit electrical signals between the display and the processor. Due to the limited internal space of the electronic device, the distance between the antenna 2 and the electrical connector 6 can be relatively close. In order to avoid interference, it is necessary to shield the electrical connector 6 using a shielding structure to prevent electromagnetic interference between the electrical signals transmitted by the electrical connector 6 and the signals of the antenna 2, to ensure the stability of signal transmission, and thus to ensure the working performance of the electronic device.

[0102] For the convenience of description, the embodiments of the present application take a mobile phone as an example to specifically describe the electronic device.

It should be understood that the back cover and the display screen are located on opposite sides of the middle frame, and the back cover and the display screen are oppositely arranged. The display screen and the back cover can be provided with the middle frame, the circuit board, the electrical connector, and the like.

[0106] Optionally, the electronic device can further include a front cover, the front cover is arranged opposite to the back cover, the front cover can be used to accommodate or fix the display screen, that is, the display screen can be mounted or embedded in the front cover, and the front cover can be fixedly connected with the shell. Of course, the electronic device can also not include the front cover, that is, the electronic device is a full-screen electronic device.

It should be noted that the antenna structure illustrated in the embodiments of the present application does not constitute a specific limitation on the antenna. In another embodiment of the present application, the antenna 2 can be formed on the metal back cover of the electronic device.

[0122] In some embodiments, the antenna 2 can include a metal frame and a metal middle frame, wherein the metal frame can be arranged along the outer periphery of the metal middle frame. For example, the metal frame can include a first side and a third side arranged opposite to each other, and a second side and a fourth side arranged opposite to each other, and the first side, the second side, the third side and the fourth side are connected in turn. The connection mode between the metal frame and the metal middle frame includes but is not limited to welding, clamping and one-piece injection molding. Among them, the material of the metal frame and the metal middle frame can be aluminum or aluminum alloy, magnesium or magnesium alloy, or stainless steel material, etc. It should be noted that the specific structure, material and connection mode of the metal frame and the metal middle frame are not limited in the embodiments of the present application.

[0123] In some embodiments, a plurality of antennas 2 can be arranged on the metal frame and / or the metal middle frame. The plurality of antennas 2 can include at least one of a main antenna, a diversity antenna, a WIFI antenna, a GPS antenna and a Bluetooth antenna, etc. Alternatively, the plurality of antennas 2 can include at least one of a low-frequency antenna, a medium-frequency antenna, a medium-high-frequency antenna and a high-frequency antenna, etc.

[0124] The above-mentioned antennas 2 can be electrically connected to the first circuit board 7. Each antenna 2 can independently transmit antenna signals, avoiding coupling between the antennas 2 and affecting the signal quality.

[0125] The above-mentioned antennas 2 include antenna radiators, and different antenna radiators can be formed on the metal middle frame of the electronic device, or the antenna radiators can also be used as the metal frame of the electronic device.

[0126] In some embodiments, at least part of the antenna 2 is used as a metal frame of the electronic device, and several antenna radiators can jointly form the metal frame. In comparison, the lengths of the first and third edges of the metal frame are greater than the lengths of the second and fourth edges, and the electrical connector can be arranged at a position close to or adjacent to the first edge or the third edge.

[0127] The structure and layout of the electrical connector, the first circuit board, the second circuit board, and the support assembly inside the electronic device shown in the specific embodiments will be described in detail below. The connection structure or spatial layout provided in the following embodiments is only an example, and a person skilled in the art can adjust the positions or specific structures of the devices according to actual needs. Figure 5

[0128] Please refer to the accompanying drawings Figures 4-8 The electronic device includes an antenna 2, a first circuit board 7, a second circuit board 5, an electrical connector 6, and a support assembly 4. At least part of the metal frame of the electronic device (part of the shell 1) can be used as the antenna 2, for example, at least part of the first edge or the third edge of the metal frame of the electronic device can be used as the antenna 2. The first circuit board 7, the second circuit board 5, the electrical connector 6, and the support assembly 4 are all arranged on the inner side of the antenna 2, and the first circuit board 7, the second circuit board 5, the electrical connector 6, and the support assembly 4 are all arranged between the back cover and the display screen of the electronic device.

[0129] The support assembly 4 is adapted to be connected to the first circuit board 7 and can be used to fix the first circuit board 7, which can also be referred to as a mainboard support assembly. The support assembly 4 includes a support 41, a metal piece 42, and a metal terminal 43. The support 41 and the metal piece 42 can be fixedly connected, and the metal piece 42 and the metal terminal 43 can be fixedly connected. Alternatively, the metal terminal 43 can also be part of the metal piece 42, that is, the metal piece 42 and the metal terminal 43 can be either a split structure or an integral structure.

[0130] The first circuit board 7 and the second circuit board 5 are electrically connected through the electrical connector 6, which can be used to transmit electrical signals between the first circuit board 7 and the second circuit board 5. The support assembly 4 is buckled above the first circuit board 7 and the second circuit board 5, and the metal terminal 43 in the support assembly 4 is connected to the electrical contact position 71 (which can be referred to in detail in the description of the electrical contact position 71) on the first circuit board 7. In this way, a good grounding conduction effect can be achieved. Figure 16

[0131] ​​It should be noted that the electrical contact position 71 on the first circuit board 7 can be a position at which the first circuit board 7 is electrically connected to other metal devices (such as a metal plate). The electrical contact position on the first circuit board can also be referred to as an electrical contact area, which can be a metal area exposed by the first circuit board. For example, the electrical contact area can be a copper-exposed area of the first circuit board.

[0132] In the embodiment, the electrical contact position 71 on the first circuit board 7 can be a grounding point on the first circuit board. The metal terminal is in contact with the grounding point on the first circuit board, which can form a grounding shield to effectively prevent electromagnetic interference and ensure the stability of signal transmission.

[0133] As understood by those skilled in the art, in some cases, a metal sheet is provided on the support in some existing electronic devices. The metal sheet provided on the support in the prior art only serves to strengthen the support and cannot serve as a shield. In order to overcome the imperfections of the prior art, the metal member provided on the support is bent or processed in the embodiments of the present application, so that at least a part of the metal member forms a metal terminal, or the metal member is processed and connected with the metal terminal, and the metal terminal is further connected with the electrical contact position on the second circuit board. In this way, a good shielding effect is achieved. That is, the metal member provided on the support is used as a shielding member for shielding the electronic devices provided on the mainboard.

[0134] In an embodiment, the electronic device can be an electrical connector, or a chip, a resistor, a capacitor, or other electronic devices. The metal member serves as a shield and also serves to strengthen the support. For the sake of brevity and convenience of description, the embodiments of the present application are mainly described by taking the electronic device as an electrical connector, but it should be understood that the specific type of the electronic device is not limited thereto. The support assembly of the present application, especially the shielding function of the metal member therein, can be used to shield any appropriately arranged electronic device provided on the mainboard, such as a chip, a resistor, a capacitor, or other electronic devices.

[0135] The support assembly 4 described above can be a support member accommodated in the housing of the electronic device, which can be used to enhance the mechanical robustness of the electronic device, protect the internal devices of the electronic device, and separate the internal devices from each other. For example, some electronic devices are mounted on the circuit board, so that the direct contact of the circuit board with the front cover or the display screen can damage the display screen. Arranging the support assembly between the circuit board (or the circuit board and the electrical connector) and the display screen can prevent the electronic devices from directly contacting the display screen. In addition, the support assembly can also isolate the electrical connector from the antenna, at least shield the electromagnetic interference of the electrical connector on the antenna, and the electromagnetic interference of the antenna on the electrical connector.

[0136] It can be known from the above that the electronic device provided in the embodiments of the present application integrates the metal piece onto the support, and then integrates the metal terminal onto the metal piece. The electrical contact position of the metal terminal and the circuit board can be electrically connected in a Z-direction compression manner, and the electrical contact position of the metal terminal and the circuit board can also be electrically connected in a welding manner, thereby achieving the shielding effect of the electrical connector. The structure is simple, convenient to disassemble and assemble, forms good grounding shielding, can effectively prevent electromagnetic interference, and ensures the stability of signal transmission.

[0137] Compared with the prior art scheme of arranging a shielding cover outside the electrical connector and then welding the shielding cover to the mainboard support, the present application can avoid the defect that the shielding cover is easily deformed when the electrical connector is disassembled first. The electronic device repeatedly disassembled and assembled will not affect the shielding effect of the electrical connector, and can always maintain good contact (good contact of the electrical contact position of the metal terminal and the circuit board). The electronic device is compressed by the support assembly above the electrical connector, which can save Z-direction space, and can alleviate the defect that the existing support compression structure on the shielding cover occupies a large space of the electronic device and affects the compact layout of the internal components of the electronic device.

[0138] In some embodiments, the material of the support 41 can be a non-metal material, for example, the material of the support 41 can be plastic. In the support assembly 4, the support 41 can be a plastic support. The insulating body made of plastic material helps to reduce the weight of the electronic device, and also plays a role in supporting, fixing or protecting the internal components such as the circuit board of the electronic device.

[0139] In some embodiments, the metal piece 42 is arranged on the support 41. The material of the metal piece 42 can be various steel materials, for example, the material of the metal piece can be stainless steel. In the support assembly 4, a steel sheet can be used as the metal piece 42, which can also be called a reinforcing steel sheet. Further, a stainless steel sheet can be used as the metal piece. By arranging the metal piece, the strength of the support can be enhanced, the rigidity of the support can be improved, and the metal shielding effect can also be achieved.

[0140] In some embodiments, the thickness of the metal piece 42 can be 0.2-0.35mm, further can be 0.25-0.3mm, further can be 0.26-0.28mm; typically but not limited to, for example, 0.25mm, 0.26mm, 0.28mm, 0.3mm. In the electronic device, there is no need to additionally arrange a metal shielding cover. The thickness of the metal piece can be smaller than the thickness of the existing metal shielding cover, thereby saving the occupied space and not affecting the layout of the electronic device. At the same time, by arranging the metal piece with an appropriate thickness, the metal shielding and support strength can be achieved.

[0141] As Figure 9 and Figure 13As shown, in some embodiments, the metal component 42 may include a metal component body 421 and a bent portion 422. The bent portion 422 may be respectively disposed at any two, three, or more ends of the metal component body 421, and the metal terminal 43 may be fixed to the metal component body 421. It is understood that the shape of the metal component can be of various types, such as quadrilateral (e.g., rectangle), pentagon, hexagon, or various irregular shapes, and the placement of the bent portion can be selectively configured according to the shape of the metal component or the position of the metal terminal. For example, when the shape of the metal component is rectangular, the bent portion may be disposed at... Figure 9 The second direction, and connects the metal terminal to the metal body. Figure 9 The first direction in; or the bending part can be set in Figure 9 The first direction in which the metal terminal is connected to the metal body. Figure 9 The second direction in; or the bending part can be set in Figure 9 The first and second directions are specified, and the metal terminal can be connected to either end of the metal body. Similarly, when the metal part is irregularly shaped, a bending portion can be provided along the outer periphery of the metal body, or a bending portion can be provided along a portion of the outer periphery of the metal body. The embodiments of this application do not limit the specific arrangement of the bending portion; it can be adjusted according to the shape of the metal part, the position of the metal terminal, or other actual needs.

[0142] Understandably, to improve the shielding effect, any of the ends of the metal part 42 can be bent to form a bent portion 422. For example... Figure 8 and Figure 9 As shown, for example, the two, three, or four ends of the metal part 42 can be bent to form a bend 422, and the electrical connector 5 can be located between these bends 422. That is, any two or more ends of the electrical connector 5 can be covered by the bends 422, further improving the shielding effect. Specifically, as shown... Figure 9 As shown, on one side end of the metal part 42, at Figure 9 Metal terminal 43 is provided in the first direction, and metal terminal 43 is connected to... Figure 17 The electrical contact position 71 of the first circuit board 7 shown in the diagram is spring-loaded, which can serve to... Figure 9 The shielding effect of interference signals in the first direction. The metal part 42... Figure 9 The circuit is bent in the second direction to form a bent portion 422; furthermore, the bent portion 422 can extend outward to form a contact portion, which connects to the electrical contact position of the first circuit board, thereby shielding it from... Figure 9 This acts as a second source of interference. Therefore, it improves the shielding effect, providing comprehensive shielding for the electrical connector, effectively preventing electromagnetic interference and ensuring the stability of signal transmission.

[0143] As shown in Figure 14 some embodiments, the metal terminals can include a first metal terminal 431 and a second metal terminal 432, wherein the first metal terminal 431 can be arranged along a first direction in the lateral direction of the metal piece 42, and the second metal terminal 432 can be arranged along a second direction in the longitudinal direction of the metal piece 42. Figure 9 Figure 9 As shown in

[0144] Continuing as shown in Figure 14 some embodiments, the second metal terminal 432 can be arranged on the left and right sides of the metal piece 42, and can shield interference sources from the left and right sides of the metal piece 42. On the one hand, the second metal terminal can be arranged directly on the left and right sides of the metal piece (in the longitudinal direction of the metal piece), and the first metal terminal can be arranged in the lateral direction of the metal piece, and these metal terminals can be electrically connected to the electrical contact positions of the circuit board, which are electrically connected to the ground of the circuit board, thereby improving the grounding shielding effect and providing omnidirectional shielding of interference signals. On the other hand, the left and right sides of the metal piece can be bent to form a bent portion, and then the second metal terminal can be added to the bottom of the bent portion, and the first metal terminal can be arranged in the lateral direction of the metal piece, and these metal terminals can be electrically connected to the electrical contact positions of the circuit board, thereby improving the grounding shielding effect and providing omnidirectional shielding of interference signals. On the other hand, only the first metal terminal can be arranged, which can be arranged in the lateral direction of the metal piece (the longitudinal direction of the metal piece can be bent), and the arrangement direction of the first metal terminal is close to the position of the antenna area.

[0145] In order to improve the stability of the connection and the reliability of disassembly and assembly, as shown in Figure 10 or Figure 11 the connection between the metal piece 42 and the support 41 is fixed connection. For example, the metal piece 42 is embedded in the plastic support 41 by in-mold injection molding, or other fixed connection methods known in the art can also be used.

[0146] In some embodiments, as shown in Figure 10 or Figure 11 the metal piece 42 and the support 41 are tightly combined by in-mold insert injection molding. Further, the metal piece can be a stainless steel sheet, and the support can be a plastic support, and the stainless steel sheet is integrated by being embedded in the plastic support by in-mold injection molding. The metal piece can play the role of metal shielding and supporting strength.

[0147] Thus, by embedding the stainless steel sheet in the support by in-mold injection molding, the stainless steel sheet is integrated on the support, which can achieve the effect of repeated disassembly and assembly without affecting the shielding effect, improve the disassembly performance, and the shielding effect is good, and the structure design is simple and easy to produce. ​

[0148] The aforementioned metal terminals and metal parts can be either an integral structure or a separate structure. (See appendix to this application.) Figure 8 and attached Figure 9 Exemplary examples show metal terminals and metal parts with a separate structure, but those skilled in the art will understand that this is not the only possibility, and the two can also be an integral structure.

[0149] Specifically, in some embodiments, the metal component can be integrally formed with the metal terminal; that is, the metal terminal can be part of the metal component, and a portion of the metal component can be processed to form the metal terminal. This results in a stable and reliable structure, facilitates manufacturing, and saves raw materials.

[0150] In other embodiments, such as Figure 8 As shown, the metal terminal 43 and the metal part 42 can be separate structures, and the metal part 42 can be welded together with the metal terminal 43. This ensures good connection reliability and facilitates operation.

[0151] Specifically, the metal part 42 and the metal terminal 43 can be connected by spot welding, whereby the metal terminal is spot welded onto the metal part to form a whole with the metal part. This is used to shield the electrical connector from interference with the antenna, ensuring a stable and reliable connection and good shielding effect.

[0152] Therefore, by spot welding metal terminals onto metal parts and making reliable contact with the electrical contact points of the circuit board through Z-axis positive pressure, reliable pressing can be achieved with minimal impact from dimensional assembly, thus effectively shielding the electrical connector.

[0153] In some embodiments, the metal terminal 43 can be made of various steel materials, such as stainless steel. Using stainless steel for the metal terminal ensures both strength and good elasticity, allowing it to shield against electromagnetic interference while also serving a grounding function.

[0154] In some embodiments, the thickness of the metal terminal 43 can be 0.08-0.15 mm, more specifically 0.09-0.12 mm, or even 0.1 mm. Using a metal terminal of suitable thickness ensures both strength and good elasticity, allowing it to be used for shielding electromagnetic interference while also serving a grounding function.

[0155] It is understood that the metal terminal 43 can be a flexible contact spring, and the metal terminal can be arranged along the length direction (lateral direction) of the metal part; to improve grounding performance, multiple metal terminals can also be provided, arranged both along the length direction (lateral direction) and the width direction (longitudinal direction) of the metal part. The above can be selectively configured according to the actual needs of the electronic device.

[0156] likeFigure 15 and Figure 16 As shown in FIG. 7, the metal terminal 43 is provided with a certain arc-shaped lead-out spring leg 4311. By contacting the lead-out spring leg 4311 of the metal terminal 43 with the electrical contact position 71 of the first circuit board 7, the grounding function can be achieved, and electromagnetic interference can be shielded. Specifically, the metal terminal 43 includes at least one spring leg 4311 having elasticity, the root of the spring leg 4311 is integrally arranged with the metal terminal 43, and the other end of the spring leg 4311 is a free end. The metal terminal 43 can be provided with one, two or more spring legs 4311, and the plurality of spring legs 4311 can be arranged at equal intervals along the length direction of the metal terminal 43. It should be understood that the number of spring legs 4311 can correspond to the exposed copper contact area on the first circuit board 7, and the specific number of spring legs 4311 in the metal terminal 43 is not limited in the embodiments of the present application, and can be determined according to the actual design situation.

[0157] In order to improve the grounding performance and better play the shielding effect, in some embodiments, the metal terminal 43 is provided with three spring legs 4311, and the three spring legs 4311 are arranged at equal intervals along the length direction of the metal terminal 43.

[0158] When the metal terminal 43 is not connected with the first circuit board 7, the spring leg 4311 on the metal terminal 43 can be arranged in a certain arc shape, and the free end of the spring leg 4311 on the metal terminal 43 can extend downward or be inclined; the spring leg is designed as an arc-shaped bending feature, for example, the spring leg can be designed as a 1 / 4 circular arc-shaped spring leg. In this way, the resilience effect of the metal terminal can be improved.

[0159] As can be seen from the above, the electronic device provided by the embodiments of the present application can effectively alleviate the problem that the reliability of the shielding function and the disassembly and assembly of the existing solution of the interference between the electrical connector and the antenna signal cannot be considered, has the advantages of reliable shielding effect, the shielding effect is not affected by multiple disassembly and assembly, saving Z-direction space, etc. Specifically, (1) the bracket assembly integrates the bracket, the metal piece and the metal terminal, the metal piece and the metal terminal are integrated on the bracket, which can avoid the problem of deformation of the shielding piece caused by disassembly and assembly of the electrical connector, and achieve the effect of repeated disassembly and assembly without affecting the shielding performance; (2) the metal terminal is spot-welded on the metal piece, and reliable contact can be achieved between the Z-direction positive pressure and the electrical contact position of the circuit board, which can avoid the problem that the contact between the existing shielding cover and the shielding frame is unreliable, and achieve the effect of reliable compression and little influence by size assembly; (3) only the bracket assembly is used for compression above the electrical connector, which makes the Z-direction space of the electrical connector position more compact, which can avoid the problem that the existing electrical connector needs a large structure space above, and achieve the effect of saving Z-direction space.

[0160] Further, as shown in FIG. 7, Figure 8As shown, in some embodiments, in order to further improve the connection ground reliability, so that the connection is more stable, the support assembly 4 further comprises a compression intermediate layer 44 which can be attached to the inner surface of the metal piece 42. It should be noted that the inner surface of the metal piece 42 is the surface of the metal piece 42 close to the electrical connector 6 or the second circuit board 5.

[0161] The compression intermediate layer 44 can be arranged between the metal piece 42 and the second circuit board 5, that is, one end surface of the compression intermediate layer 44 can be in close contact with the metal piece 42, and the other end surface of the compression intermediate layer 44 can be in contact with the upper surface of the second circuit board 5. The arrangement of the compression intermediate layer can be used to compress the electrical connector in the Z direction to prevent loosening.

[0162] In some embodiments, the compression intermediate layer 44 can be a compression foam, or it can also be a compression intermediate layer made of other soft materials. The compression foam is arranged between the metal piece and the first circuit board, which can be used to compress the electrical connector in the Z direction, thereby improving the stability and reliability of the connection and preventing loosening. It can be understood that the compression intermediate layer can be a compression foam, but it is not limited thereto, and other materials can also be selected according to actual conditions.

[0163] In some embodiments, the first circuit board 7 can be the main board of an electronic device, and the first circuit board 7 can be a PCB board. Some electronic components can be fixed on the circuit PCB board, and these components can be power management chips, resonators, duplexers, switches and other electronic components. The second circuit board 5 can be a FPCB flexible printed circuit board, and the internal wiring of the FPCB flexible printed circuit board can include screen signal lines, main board signal lines, etc.

[0164] In some embodiments, the electrical connector 6 can include a FPCB connector provided with an insertion surface for inserting and docking the FPCB flexible printed circuit board or FFC flexible flat cable. The FPCB connector has the characteristics of high reliability, light weight, thin thickness, good bending property, etc. It should be understood that the electrical connector can include a FPCB connector, but it is not limited thereto, and other connectors can also be selected according to actual conditions.

[0165] Further, the PCB board can be provided with a PCB connector, for example, a ZIF (Zero Insertion Force) connector is welded on the PCB board, the FPCB flexible printed circuit board is connected to the FPCB connector, and the FPCB connector is provided with a gold finger, which can be inserted into the ZIF connector through the gold finger on the FPCB connector. In this way, the FPCB flexible printed circuit board is connected to the FPCB connector, the ZIF connector is welded on the PCB board, and the FPCB connector is inserted into the ZIF connector, realizing the circuit communication between the FPCB flexible printed circuit board and the PCB board.

[0166] It should be understood that when the electric connector comprises the FPCB connector, one end of the FPCB flexible printed circuit board can be connected with a component such as a display screen or a camera, and the other end can be connected with the ZIF connector on the PCB board through the FPCB connector. Moreover, the metal terminal can be integrated on the metal piece, the metal terminal is electrically connected with the electric contact position of the PCB board, one side of the metal piece connected with the metal terminal is not subjected to the bending treatment, and the remaining sides of the metal piece are subjected to the bending treatment to extend downward, so that the FPCB connector is wrapped on four sides to achieve the shielding effect. Furthermore, in order to enable the FPCB flexible printed circuit board to extend outward, enable the signal line to be led out, and facilitate the signal connection between the FPCB flexible printed circuit board and the component such as the display screen, a notch can be formed on the metal piece, the FPCB flexible printed circuit board can be led out outward through the notch, or a gap can be reserved between the support assembly and the PCB board, so that the FPCB flexible printed circuit board can be led out outward through the gap, that is, as long as the FPCB flexible printed circuit board can pass through the gap to be led out outward.

[0167] As shown in Figure 8 In some embodiments, the FPCB connector (the electric connector 6) can comprise a board-to-board connector (BTB connector), and the FPCB flexible printed circuit board is connected with the PCB board through the BTB connector.

[0168] Specifically, the board-to-board connector (the electric connector 6) can comprise a connector male head 61 and a connector female seat 62 which can be buckled with each other; for example, the connector male head 61 can be arranged on the FPCB flexible printed circuit board, and the connector female seat 62 can be arranged on the PCB board; or the connector female seat 62 can be arranged on the FPCB flexible printed circuit board, and the connector male head 61 can be arranged on the PCB board, and when the connector male head 61 and the connector female seat 62 are buckled together, the circuit communication between the FPCB flexible printed circuit board and the PCB board can be achieved. The connection mode between the connector male head or the connector female seat and the FPCB flexible printed circuit board is not limited, for example, the connection mode can be welding, and the connection mode between the connector male head or the connector female seat and the PCB board is not limited, for example, the connection mode can be welding. The specific structure or model of the board-to-board connector is not limited, and can be selected and set by the person skilled in the art according to the actual situation.

[0169] In order to improve the stability of the connection, or facilitate the fixing or stable installation, as shown in Figure 8 In some embodiments, the electronic device can further comprise a containing part 8 for containing the first circuit board 7, and the containing part 8 can have a containing groove 81 for containing or accommodating the first circuit board 7.

[0170] Specifically, asFigure 8 and Figure 16 As shown in FIG. 8, the electronic device includes a receiving member 8, which is provided with a receiving groove 81 in which the first circuit board 7 can be disposed. Further, to facilitate fixation or installation, at least one positioning post 811 can be disposed in the receiving groove 81, and the first circuit board 7 is provided with a positioning hole 72 corresponding to the positioning post 811, which plays a role of accurate positioning and makes the installation stable.

Further, the first circuit board 7 is provided with two positioning holes 72, and the two positioning holes 72 are respectively disposed at the diagonally opposite positions of the first circuit board 7.

[0177] As shown in Figure 8 , the second circuit board 5 can be a FPCB flexible printed circuit board, the first circuit board 7 can be a PCB board, and the electrical connector 6 can include a FPCB connector. The FPCB connector can be a ZIF connector or a board-to-board connector. This embodiment takes the board-to-board connector as an example. The connector male head 61 is arranged on the FPCB flexible printed circuit board, and the connector female seat 62 is arranged on the PCB board. When the connector male head 61 and the connector female seat 62 are buckled together, the electrical circuit communication between the FPCB flexible printed circuit board and the PCB board can be achieved. The accommodating part 8 is provided with an accommodating groove 81, and the accommodating groove 81 is provided with a positioning column 811.

[0178] As shown in Figure 5 and Figure 6 , the relative positions of the support assembly 4, the FPCB flexible printed circuit board (second circuit board 5), the electrical connector 6, and the PCB board (first circuit board 7) in the machine relative to the antenna 2 region, Figure 6 , the antenna 2 can be in a long strip shape and distributed on the left side of the support assembly 4. Therefore, the metal piece 42 (stainless steel sheet) and the metal terminal 43 in the support assembly 4 can shield the interference source from the left side. The right side of the FPCB connector can shield the interference source from the right side by extending the metal piece downward, or the right side can shield the interference source by the cooperation of the metal piece and the accommodating part. At the same time, the right side can reserve a gap for the FPCB flexible printed circuit board to pass through. In addition, Figure 6 , the front-rear direction can be shielded by bending the metal piece to extend downward, as shown in Figure 13 . Thus, the interference source from the front-rear direction in Figure 6 can be shielded. Therefore, by the cooperation of the above-mentioned components, the omnidirectional shielding effect of the electrical connector is achieved.

[0179] The specific assembly method of the above device can be

[0180] As shown in Figure 16 and Figure 8 , the PCB board with the connector female seat 62 welded on the surface is assembled in the accommodating groove 81 of the accommodating member 8, and is positioned by cooperating with the positioning hole 72 on the PCB board through the positioning column 811 in the accommodating groove 81, which plays a role of accurate positioning;

[0181] As shown in Figure 18 and Figure 8 , the connector male head 61 is welded with the FPCB flexible printed circuit board, and the connector male head 61 and the connector female seat 62 are buckled together to electrically connect the FPCB flexible printed circuit board with the PCB board. The internal wiring of the FPCB is usually a screen signal line and a mainboard signal line, so the shielding requirement for the antenna is very high;

[0182] As shown in Figure 10 and Figure 8 , the plastic support 41 and the stainless steel sheet (metal piece 42) are combined together by the mold insert injection molding method, the metal terminal 43 is spot welded on the stainless steel sheet to form a whole with the stainless steel sheet, and the compression foam (compression intermediate layer 44) can be attached to the inner surface of the stainless steel sheet, thereby composing the support assembly 4. Further, as shown in Figure 6 or Figure 7 , the support assembly 4 is arranged on the FPCB flexible printed circuit board and the PCB board, the elastic legs of the metal terminal 43 in the support assembly 4 are compressed on the PCB board and correspond to the electrical contact areas of the PCB board one by one, which plays a good grounding conduction role. In this way, the insert stainless steel sheet with the metal terminal is firmly compressed on the PCB board around the FPCB electrical connector, realizes reliable contact, and thus achieves the shielding effect. When the FPCB electrical connector needs to be disassembled, only the support needs to be disassembled, and the contact effect of the elastic sheet is not affected by repeated disassembly and assembly.

[0183] In addition, as shown in Figure 8 , the screw 9 can be sequentially inserted through the through hole 411 on the support 41 and the hole structure 82 on the accommodating member 8, that is, the support assembly 4 is locked on the accommodating member 8 by the screw 9. The above assembly process can be sequentially referred to Figure 17 , Figure 16 , Figure 18 , Figure 10 , Figure 7 (or Figure 6 ).

[0184] In conclusion, in the embodiment of the application, by integrating the metal piece and the metal terminal on the bracket, spot welding the metal terminal on the metal piece, and compressing the ground in the Z direction of the electrical contact area with the circuit board, the electrical connector can be repeatedly disassembled without affecting the shielding effect of the surrounding metal piece and metal terminal, the Z direction compression contact of the metal terminal is reliable, and the size assembly has less influence, the upper part of the electrical connector is compressed through the bracket assembly, the Z direction space is saved, and the effect is achieved.
