[0025] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0026] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0027] The circuit board assembly 100 provided in the embodiment of the present application can be applied to electronic devices, and specifically, can be applied to a scenario in which the electronic device is provided with a circuit board assembly 100 composed of at least two stacked circuit boards.

[0028] In the related art, in the scenario where two circuit boards are stacked, the connection between the two circuit boards can be achieved through a BTB (Board to Board) connector, where one circuit board can be a circuit board electrically connected to functional devices such as a display screen and a camera, and the other circuit board can be a main board. BTB connectors are generally connected by plugging male and female sockets, and the male and female sockets have a certain thickness. Therefore, the thickness of the stacked circuit board assembly cannot be effectively reduced.

[0029] The circuit board assembly 100 and the electronic device provided in the embodiment of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] Figure 1 A possible structural diagram of a circuit board assembly 100 provided in an embodiment of the present application is shown. Figure 1 As shown, the circuit board assembly 100 includes a first circuit board 10, a second circuit board 20, a plurality of first pins 301, and a first slot body 401 opened on the second circuit board 20. The first circuit board 10 and the second circuit board 20 are arranged opposite to each other and stacked, and the first circuit board 10 and the second circuit board 20 form a receiving space after being buckled together. The plurality of first pins 301 are located in the receiving space, and the first end of any first pin 301 among the plurality of first pins 301 is electrically connected to the first circuit board 10, and the second end of any first pin 301 is electrically connected to the second circuit board 20 through the first slot body 401, and the plurality of first pins 301 are arranged in at least one row.

[0031] Specifically, the first circuit board 10 and the second circuit board 20 can be stacked and arranged relative to each other, and there is an accommodation space between the first circuit board 10 and the second circuit board 20. A plurality of first pins 301 are arranged in the accommodation space. The first end of each of the plurality of first pins 301 is electrically connected to the first circuit board 10, and the second end of each first pin 301 is electrically connected to the second circuit board 20 through the first groove body 401, thereby realizing that the functional components electrically connected to the first circuit board 10 (for example: camera module, speaker module, microphone module) are electrically connected to the second circuit board 20 through the first pin 301, thereby completing the transmission of electrical signals.

[0032] Exemplarily, the first circuit board 10 may be a PCB (Printed Circuit Board), and the second circuit board 20 may be a FPC (Flexible Printed Circuit).

[0033] It can be understood that the plurality of first pins 301 are arranged into at least one row, the plurality of first pins 301 in the row are arranged extending along the length direction of the circuit board assembly 100, and the front and rear rows of the plurality of rows of first pins 301 are arranged along the width direction of the circuit board assembly 100. Specifically, the plurality of first pins 301 may be a row of first pins 301, the row of first pins 301 including a plurality of first pins 301, or the plurality of first pins 301 may include a plurality of rows of first pins 301, each row of first pins 301 including a plurality of first pins 301.

[0034] It should be noted that when multiple first pins 301 are arranged in multiple rows, the space in the width direction of the circuit board assembly 100 can be more fully utilized. Without lengthening the circuit board assembly 100, the number of first pins 301 can be increased, thereby increasing the number of functional devices that can be electrically connected to the first pins 301, thereby improving the functionality of the circuit board assembly 100.

[0035] For example, Figures 1 to 4 As shown, along Figure 1The direction indicated by the arrow in is the width direction of the circuit board assembly 100. In this direction, two rows of first pins 301 are arranged between the first circuit board 10 and the second circuit board 20. In this way, the space in the width direction of the circuit board assembly 100 is fully utilized. While the length of the circuit board assembly 100 remains unchanged, a larger number of first pins 301 are arranged, thereby ensuring that the circuit board assembly 100 supports more functional devices. Since the length of the circuit board assembly 100 does not need to be further increased, the width of the electronic device provided with the circuit board assembly 100 does not need to be further widened (the length direction of the circuit board assembly 100 is the same as the width direction of the electronic device), so that the electronic device has a good grip.

[0036] Specifically, the first pin 301 may be a metal piece, which can ensure stable impedance and can stably transmit electrical signals.

[0037] Exemplarily, the first slot body 401 can be disposed on the second circuit board 20, and the first slot body 401 can be processed on the second circuit board 20 by a Cavity (local recess) process to remove part of the base material on the second circuit board 20 to obtain the first slot body 401. In this way, not only can the seat body in the connector connecting two circuit boards in the related art (generally a female seat is disposed on the PCB board, which can be understood here as omitting the female seat on the second circuit board 20) be omitted, thereby reducing the overall thickness of the circuit board assembly 100.

[0038] It can be understood that the above-mentioned first groove body 401 is opened on the surface of the second circuit board 20 facing the first circuit board 10. Since a portion of the first pin 301 extends into the first groove body 401, the thickness between the first circuit board 10 and the second circuit board 20 can be further reduced on the basis of eliminating the connector seat.

[0039] It should be noted that, when the first circuit board 10 is buckled into the second circuit board 20, that is, when the first pin 301 is inserted into the first slot 401, the side of the first pin 301 is supported by the first slot 401, that is, the first slot 401 can not only realize electrical connection between the first pin 301 and the second circuit board, but also provide structural support for the first pin 301, thereby improving the contact reliability between the first pin 301 and the second circuit board 20.

[0040] Further optionally, a groove or an avoidance area can also be opened on the first circuit board. In this way, the first end of the above-mentioned first pin 301 can also be electrically connected to the first circuit board 10 through the above-mentioned groove or the avoidance area, thereby further eliminating the seat body in the connector connecting the first circuit board 10 and the second circuit board 20 in the related technology (generally, the male seat is set on the FPC board, which can be understood here as eliminating the male seat on the first circuit board 10).

[0041] Further optionally, the first pin 301 can be directly welded to the first circuit board 10 through a welding piece with conductive properties. Specifically, the welding piece can be a tin bead. The circuit board assembly 100 provided in the embodiment of the present application is electrically connected to the first circuit board 10 through the first end of multiple first pins 301, and the second end of the first pin 301 is electrically connected to the second circuit board 20 through the first slot 401. On the one hand, the electrical connection function between the first circuit board 10 and the second circuit board 20 is realized through the first pin 301, so that the functional device electrically connected to the first circuit board 10 is connected to the second circuit board 20 through the first pin 301 to realize the transmission of electrical signals. On the other hand, since the second end of the first pin 301 is connected to the second circuit board 20 through the first slot 401, the connector seat used to electrically connect the first circuit board 10 and the second circuit board 20 in the prior art is omitted, thereby reducing the overall thickness of the circuit board assembly 100 and meeting the slimming requirements of the electronic device using the circuit board assembly 100. Furthermore, multiple rows of first pins 301 can be arranged along the width direction of the circuit board assembly 100 to ensure that more first pins 301 are arranged while the length of the circuit board assembly 100 remains unchanged, ensuring that the above-mentioned circuit board assembly 100 can support the operation of more functional devices.

[0042] Optionally, the circuit board assembly 100 provided in the embodiment of the present application further includes a first metal layer 402 . The first metal layer 402 is disposed on the inner surface of the first slot body 401 and is located between the first pin 301 and the first slot body 401 .

[0043] Specifically, the above-mentioned first slot body 401 may include a first slot body 401 opened on the second circuit board 20, and a first metal layer 402 arranged in the first slot body 401, and the first metal layer 402 is used to contact and electrically connect with the first pin 301, so that the above-mentioned first pin 301 is electrically connected to the second circuit board 20 through the first slot body 401 and realizes signal transmission.

[0044] Furthermore, in order to ensure the stability of the electrical connection, the first metal layer 402 may be a noble metal layer. For example, the first metal layer 402 may be a copper-plated layer.

[0045] Thus, the first metal layer 402 is provided in the first slot 401, which improves the stability of the electrical connection between the first pin 301 and the second circuit board 20, thereby ensuring that the electronic device provided with the circuit board assembly 100 has more stable performance and longer service life.

[0046] Optionally, the first slots 401 in the circuit board assembly 100 provided in the embodiment of the present application are arranged in at least one row, and the number and arrangement of the first slots 401 are the same as those of the plurality of first pins 301 .

[0047] For example, Figure 3 As shown, in the width direction of the circuit board assembly 100 , the plurality of first pins 301 are arranged in two rows, and accordingly, the first slots 401 for connecting each row of the first pins 301 to the second circuit board 20 are also arranged in two rows.

[0048] It can be understood that not only the number of rows of the above-mentioned multiple first pins 301 is equal to the number of rows of the first slot body 401, but the arrangement method of the multiple first pins 301 and the first slot body 401 is also the same, that is, when the first pins 301 are in one row, the length of the first slot body 401 is the same as the length of the first pins 301 in the row; when the first pins 301 are in multiple rows, the spacing between each row of the first pins 301 is the same as the spacing between each row of the first slot bodies 401.

[0049] In this way, the above-mentioned first slot body 401 is arranged corresponding to multiple first pins 301, which can ensure that each row of first pins 301 can contact the corresponding first slot body 401, ensure that each row of first pins 301 can be electrically connected to the second circuit board 20, and maintain the stability of the electrical connection.

[0050] Optionally, the circuit board assembly 100 in the embodiment of the present application further includes a first support seat 50 , which is disposed on a surface opposite to the first circuit board 10 and the second circuit board 20 , and at least a portion of the first pin 301 is disposed on the first support seat 50 .

[0051] Specifically, the first support base 50 may be disposed on the surface of the first circuit board 10 opposite to the second circuit board 20 , and is used to provide structural support for the first pins 301 electrically connected to the first circuit board 10 .

[0052] For example, Figures 1 to 4 As shown, the first support seat 50 may be constructed in a plate shape, and a plurality of narrow first receiving grooves may be opened on the first support seat 50, each of which is used to accommodate at least a portion of a first pin 301, thereby providing structural support for the plurality of first pins 301, so that the first pins 301 can maintain a firm electrical connection with the first circuit board 10.

[0053] It can be understood that after fixing the multiple first pins 301 on the above-mentioned first support base 50, the first support base 50 is welded or fixed to the first circuit board 10 with screws, so that the multiple first pins 301 can be more accurately and efficiently aligned with the preset positions of the first circuit board 10 where the welding parts are provided, thereby improving the assembly efficiency of the circuit board assembly 100.

[0054] Further optionally, the first support seat 50 may be made of insulating material, such as ceramic, plastic, etc.

[0055] It should be noted that in order to ensure the overall thickness of the circuit board assembly 100, the thickness of the above-mentioned first support base 50 can be controlled within an appropriate range. While further alleviating the problem of increased thickness caused by setting the first support base 50 for the circuit board assembly 100, the structural strength of the first pin 301 is also guaranteed.

[0056] Further optionally, the first end of the first pin 301 may be disposed on the first support seat 50, and the second end of the first pin 301 may be electrically connected to the second circuit board through a spring 403 disposed on the second circuit board instead of being inserted into the second circuit board through the first slot 401, which can also omit the seat of the connector for connecting the two circuit boards in the related art. Figures 5 to 10 As shown, the second circuit board 20 is provided with a spring 403 for connecting with the first pin 301. The spring 403 is a metal spring. The spring 403 is welded to the second circuit board through a welding process, and the process is simple. In this way, the first pin 301 is connected with the spring 403 provided on the second circuit board, and the seat body (generally a female seat) in the connector connecting the two circuit boards in the related art can also be omitted, thereby reducing the overall thickness of the circuit board assembly 100.

[0057] Thus, by providing the first support base 50 on the first circuit board 10 to support the plurality of first pins 301 , the overall structural stability of the circuit board assembly 100 and the functional stability of the electronic device in which the circuit board assembly 100 is provided can be further improved.

[0058] Optionally, the circuit board assembly 100 provided in the embodiment of the present application further includes a plurality of second pins 302 and a third pin 303. The plurality of second pins 302 are electrically connected to the first circuit board 10, and any second pin 302 of the plurality of second pins 302 is at least partially disposed on the first support seat 50; the plurality of third pins 303 are electrically connected to the second circuit board 20, and any third pin 303 of the plurality of third pins 303 is disposed correspondingly to a corresponding second pin 302 of the plurality of second pins 302.

[0059] Specifically, the third pin 303 is disposed on the surface of the second circuit board 20 opposite to the first circuit board 10, and is disposed one-to-one with the second pin 302, and the second pin 302 is electrically connected to the second circuit board 20 by contacting the third pin 303. It can be seen that the difference between the second pin 302 and the first pin 301 is that the first pin 301 is inserted into the second circuit board 20 through the first slot 401 and is electrically connected to the second circuit board 20, while the second pin 302 is electrically connected to the second circuit board 20 through the third pin 303.

[0060] Exemplarily, the third pin 303 may be constructed as a hook that can be slightly deformed, and the second pin 302 may be constructed as a narrow sheet that can cooperate with the hook. In this way, when the second pin 302 contacts the third pin 303, the stable contact performance of the second pin 302 and the third pin 303 can be guaranteed. Moreover, while keeping the length of the circuit board assembly 100 unchanged, since the third pin 303 and the second pin 302 are constructed as very small structural parts, more and denser second pins 302 and third pins 303 can be arranged on the circuit board assembly 100.

[0061] For example, Figures 7 to 9 As shown, a plurality of narrow second receiving grooves may be provided on the first support seat 50, and each second receiving groove is used to accommodate at least a portion of a second pin 302, thereby providing structural support for the plurality of second pins 302, so that the second pins 302 can maintain a firm electrical connection with the first circuit board 10.

[0062] Further optionally, the third pin 303 may be a metal contact soldered on the second circuit board 20 , so that the overall thickness of the circuit board assembly 100 may be further reduced.

[0063] Further optionally, the second pin 302 can be directly soldered to the first circuit board 10 through a soldering member having a conductive property. The third pin 303 can be directly soldered to the second circuit board 20 through a soldering member having a conductive property. Specifically, the soldering member can be a tin ball.

[0064] Further optionally, the second pin 302 and the third pin 303 may be metal parts, which can ensure stable impedance and can stably transmit electrical signals.

[0065] Optionally, the plurality of second pins 302 in the circuit board assembly 100 in the embodiment of the present application are arranged in at least two rows, and the at least two rows of second pins 302 are distributed on both sides of the plurality of first pins 301 .

[0066] Specifically, in the embodiment of the present application, the second pin 302 and the first pin 301 are both set on the first circuit board 10 through the first support base 50, and the multiple second pins 302 are arranged in at least two rows and distributed on both sides of the multiple first pins 301. It is possible to layout more pins while ensuring that the length of the circuit board assembly 100 remains unchanged, thereby ensuring that the above-mentioned circuit board assembly 100 supports the operation of more functional devices.

[0067] For example, Figures 7 to 9 as well as Figures 11 to 13 As shown, the second receiving grooves for receiving the second pins 302 on the first support seat 50 are arranged on both sides of the first mounting seat, and the first receiving grooves for receiving the first pins 301 are arranged in the middle of the first support seat 50. In this way, the space on the first support seat 50 can be more fully utilized, which improves the problem of insufficient number of pins caused by the circuit board assembly 100 being unable to be further extended in the length direction, and is more conducive to the space utilization and reasonable layout of the circuit board assembly 100. In addition, since the above-mentioned multiple second pins 302 need to contact and form an electrical connection with the third pin 303, the second pins 302 are arranged on the outside of the first pin 301, which also facilitates the formation of a stable connection between the second pin 302 and the third pin 303.

[0068] It can be understood that since the first pin 301 and the second pin 302 are connected to the second circuit board 20 in different ways, the type of functional device electrically connected to the first pin 301 or the second pin 302 can be determined according to actual needs.

[0069] In this way, the second pin 302 is arranged on the outside of the first pin 301 on the first support seat 50, which fully utilizes the space in the width direction of the circuit board assembly 100, and can reduce the number of first support seats 50 set between the first circuit board 10 and the second circuit board 20, thereby reducing costs and reasonably utilizing the layout space of the first support seat 50.

[0070] Optionally, the circuit board assembly 100 in the embodiment of the present application further includes a second support base 60 , which is disposed on a surface of the second circuit board 20 opposite to the first circuit board 10 , and the third pin 303 is at least partially disposed on the second support base 60 .

[0071] Specifically, the second support seat 60 may be disposed on a surface of the second circuit board 20 opposite to the first circuit board 10 , and is used to provide structural support for the third pins 303 electrically connected to the second circuit board 20 .

[0072] For example, Figure 5 , Figure 6 and Fig. 9As shown, the second support base 60 may be constructed in a plate shape, and a plurality of narrow third receiving grooves may be opened on the second support base 60, each third receiving groove being used to accommodate at least a portion of a third pin 303, thereby providing structural support for the plurality of third pins 303, so that the third pins 303 can firmly maintain electrical connection with the second circuit board 20.

[0073] It can be understood that after fixing the multiple third pins 303 on the above-mentioned second support base 60, the second support base 60 is welded or fixed with screws to the second circuit board 20, so that the multiple first pins 301 can be more accurately and efficiently aligned with the preset positions of the second circuit board 20 where the welding parts are provided, thereby improving the assembly efficiency of the circuit board assembly 100.

[0074] Further optionally, the second support seat 60 may be made of insulating material, such as ceramic, plastic, etc.

[0075] It should be noted that in order to ensure the overall thickness of the circuit board assembly 100, the thickness of the second support seat 60 can be controlled within an appropriate range. While further alleviating the problem of increased thickness caused by setting the second support seat 60 for the circuit board assembly 100, the structural strength of the third pin 303 is also guaranteed.

[0076] Thus, by disposing the second support base 60 on the second circuit board 20 to support the plurality of third pins 303 , the overall structural stability of the circuit board assembly 100 and the functional stability of the electronic device in which the circuit board assembly 100 is disposed can be further improved.

[0077] Optionally, the circuit board assembly 100 in the embodiment of the present application further includes a second slot body 601 , which is disposed through the surface of the second support seat 60 facing the first circuit board 10 , and the first pin 301 passes through the second slot body 601 and is inserted into the first slot body 401 .

[0078] Specifically, the above-mentioned multiple first pins 301 are arranged in at least one row in the middle position of the first support seat 50. In order to avoid the first pins 301 and enable the first pins 301 to be electrically connected to the second circuit board 20, a second slot body 601 needs to be provided on the second support seat 60 to accommodate the first pins 301 and enable the first pins 301 to pass through the above-mentioned second slot body 601 and be inserted into the first slot body 401 and electrically connected to the second circuit board 20.

[0079] Specifically, the second slot body 601 passes through the second circuit board 20 , so that the first pin 301 can pass through the second support seat 60 and be electrically connected to the second circuit board 20 .

[0080] It can be understood that the second slot body 601 is arranged corresponding to the first slot body 401, that is, the projection position of the second slot body on the second circuit board 20 roughly corresponds to the notch position of the first slot body, and the areas of the two are also basically consistent. In this way, the first pin 301 can be directly inserted into the first slot body 401 after passing through the second slot body 601.

[0081] Thus, by arranging the second slot body 601 on the second support seat 60, when the first circuit board 10 is buckled with the second circuit board 20, that is, when the first pin 301 is inserted into the second slot body 601, the side of the first pin 301 is supported by the structure of the second slot body 601, and the contact reliability between the first pin 301 and the second circuit board 20 is further improved. In addition, by arranging the first slot body 401 in the second slot body 601, it is convenient for the first pin 301 to be inserted into the first slot body 401 after being inserted into the second slot body 601, and the stability of the electrical connection between the first pin 301 and the second circuit board 20 is improved, thereby ensuring that the electronic device provided with the circuit board assembly 100 has more stable performance and longer service life.

[0082] Optionally, the first circuit board 10 in the circuit board assembly 100 in the embodiment of the present application is a flexible circuit board. The circuit board assembly 100 in the embodiment of the present application also includes a support plate 90, which is arranged on the side of the first circuit board 10 away from the second circuit board 20.

[0083] Specifically, since the first circuit board 10 is a flexible circuit board that is easy to bend and deform, the first pin 301 or the first support seat 50 arranged thereon may not be effectively supported. Therefore, a support plate 90 is arranged on the side of the first circuit board 10 away from the second circuit board 20 to ensure that the first pin 301 and the first support seat 50 are effectively supported.

[0084] In this way, the alignment of the first circuit board 10 and the second circuit board 20 can be more precise and stable.

[0085] The embodiment of the present application further provides an electronic device, which may include: the circuit board assembly 100 in the above embodiment. The above electronic device may also include a device body, and the circuit board assembly 100 is arranged on the device body.

[0086] Exemplarily, a structural member is disposed on the device body, and the structural member is used to support the circuit board assembly 100. The circuit board assembly 100 can be disposed on the structural member by screws or bolts to improve the installation stability between the circuit board and the device body.

[0087] It should be noted that, for the description of the structure and working principle of the circuit board assembly 100, reference may be made to the relevant description in the above embodiments, and will not be described here in detail to avoid repetition.
