[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0035] Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] As described in the background section, in order to meet the miniaturization needs of electronic devices, related technologies employ a board-to-board structure inside the electronic device, vertically connecting one circuit board to another. However, during fabrication, these related technologies suffer from poor perpendicularity between the two circuit boards, which may affect the normal operation of the electronic device.

[0037] In view of this, this application aims to provide a circuit board assembly and electronic device. A connector is provided on a first circuit board, and a clamping groove perpendicular to the first circuit board is provided on the connector. A portion of a second circuit board is disposed within the clamping groove of the connector, while another portion of the second circuit board is connected to the first circuit board. Because the clamping groove is perpendicular to the first circuit board, the clamping groove holds the second circuit board in place, ensuring a high degree of perpendicularity between the first and second circuit boards, thereby ensuring the normal operation of the electronic device.

[0038] The embodiments of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can gain a more detailed understanding of the contents of this application.

[0039] Please refer to Figures 1-5 This embodiment provides a circuit board assembly, including:

[0040] The first circuit board 100 may have multiple electronic components.

[0041] At least one connector 200 includes a body 210 and a clamping portion. The body 210 is disposed on the first circuit board 100. Exemplarily, the body 210 can be fixed to the first circuit board 100 by means of snap-fit, soldering, or other methods. The clamping portion is located on the side of the body 210 away from the circuit board, and a clamping groove 220 is formed in the clamping portion. The clamping groove 220 is perpendicular to the first circuit board 100, and an opening is formed at the end of the clamping groove 220 away from the body 210 so that other parts can enter the clamping groove 220 through the opening.

[0042] A second circuit board 300 may be provided with multiple electronic components. At least a portion of the second circuit board 300 is held in the clamping groove 220, and another portion of the second circuit board 300 is connected to the first circuit board 100. For example, a protrusion may be provided on the second circuit board 300, through which it is inserted into the clamping groove 220.

[0043] It is understood that in this embodiment, the connector 200 is disposed on the first circuit board 100, a portion of the second circuit board 300 is disposed within the clamping groove of the connector 200, and another portion of the second circuit board 300 is connected to the first circuit board 100. Since the clamping groove 220 is perpendicular to the first circuit board 100, the clamping groove 220 holds the second circuit board 300 in place, ensuring a high degree of perpendicularity between the first circuit board 100 and the second circuit board 300, thereby ensuring that the electronic device can be used normally.

[0044] Please continue to refer to Figure 2 The clamping part in this embodiment includes a first sidewall 230 and a second sidewall 240 disposed opposite to each other, and a clamping groove 220 is formed between the first sidewall 230 and the second sidewall 240. That is, the clamping groove 220 in this embodiment not only has an opening at one end opposite to the body 210, but also has two opposing lateral openings, thereby facilitating connection and cooperation with the second circuit board 300.

[0045] For example, in this embodiment, both the first sidewall 230 and the second sidewall 240 can be integrally continuous sidewalls. Alternatively, as... Figure 2 As shown, both the first sidewall 230 and the second sidewall 240 may include multiple spaced sub-sidewalls (in the structure shown in the figure, both the first sidewall 230 and the second sidewall 240 include three sub-sidewalls). It can be understood that whether the first sidewall 230 and the second sidewall 240 are continuous or not, the clamping groove 220 can achieve the clamping effect on the second circuit board 300, thereby ensuring that the first circuit board 100 and the second circuit board 300 have a high degree of perpendicularity.

[0046] In this embodiment, the second circuit board 300 can be clamped into the clamping groove 220 using an interference fit. That is, the width of the clamping groove 220 can be slightly smaller than the thickness of the second circuit board 300. The first sidewall 230 and the second sidewall 240 can be made of a material with a certain deformation capability, so that after the second circuit board 300 is inserted, it is clamped and fixed by the first sidewall 230 and the second sidewall 240. For example, in this embodiment, the height of the second circuit board 300 within the clamping groove 220 can be greater than or equal to 4 mm to ensure sufficient contact area between the second circuit board 300 and the clamping groove 220, ensuring the stability of their connection.

[0047] Please continue to refer to Figure 2 In this embodiment, the first sidewall 230 includes a first side surface 231 and a first top surface 232. The first side surface 231 is disposed facing the second sidewall 240, and the first top surface 232 is located on the side of the first sidewall 230 away from the main body 210. The first side surface 231 and the first top surface 232 are connected by a first inclined surface 233.

[0048] Similarly, the second sidewall 240 includes a second side surface 241 and a second top surface 242. The second side surface 241 is disposed facing the first sidewall 230, and the second top surface 242 is located on the side of the second sidewall 240 away from the body 210. The second side surface 241 and the second top surface 242 are connected by a second inclined surface 243.

[0049] In the direction away from the body 210, the gap between the first inclined surface 233 and the second inclined surface 243 gradually increases. With the above structure, this embodiment can utilize the first inclined surface 233 and the second inclined surface 243 to form a guide structure, thereby guiding the second circuit board 300 when it is inserted into the clamping groove 220, so as to improve the accuracy of the connection.

[0050] In one possible implementation, a flexible layer is provided on both the first side 231 and the second side 241 of this embodiment. Exemplarily, the flexible layer can be made of an insulating material, such as a rubber layer. By providing the flexible layer, wear on the third circuit board 300 caused by the first side 231 and the second side 241 can be reduced, which helps to improve the service life of the third circuit board 300.

[0051] Please continue to refer to Figure 2 and Figure 3 In this embodiment, a plurality of first reinforcing ribs 250 are provided between the first sidewall 230 and the main body 210. The first reinforcing ribs 250 are located on the side of the first sidewall 230 away from the second sidewall 240. By providing the first reinforcing ribs 250, the structural strength can be improved, and the stability of the connection between the first sidewall 230 and the main body 210 can be increased.

[0052] Similarly, a plurality of second reinforcing ribs 260 are provided between the second sidewall 240 and the body 210, and the second reinforcing ribs 260 are located on the side of the second sidewall 240 opposite to the first sidewall 230. By providing the second reinforcing ribs 260, the structural strength can be improved and the stability of the connection between the second sidewall 240 and the body 210 can be increased.

[0053] In this embodiment, the body 210 has multiple soldering pins 270 on the side opposite to the clamping portion, and the body 210 is soldered to the first circuit board 100 through the multiple soldering pins 270. Exemplarily, the soldering pins 270 in this embodiment can simultaneously solder other electronic components on the first circuit board 100 to the first circuit board 100 within a soldering device. After the connector 200 is soldered to the first circuit board 100, the second circuit board 300 is then soldered to the first circuit board 100.

[0054] In this embodiment, the soldering pins 270 can be symmetrically distributed on both sides of the body 210, and the soldering pins 270 on both sides correspond to the solder pads on the first circuit board 100, so as to reduce the space occupied by the connector 200.

[0055] Please continue to refer to Figures 2-4 In this embodiment, the main body 210 is provided with at least one positioning protrusion 280 on the side away from the clamping part, and the first circuit board 100 is provided with at least one positioning hole 110, and the positioning protrusion 280 is inserted into the positioning hole 110.

[0056] In this embodiment, the positioning protrusion 280 and the positioning hole 110 cooperate to achieve pre-positioning of the connector 200 and the first circuit board 100 before fixing, ensuring that the soldering pins 270 on the connector 200 can correspond to the corresponding solder pads on the first circuit board 100, so as to ensure the stability of the connection and improve the assembly efficiency.

[0057] In this embodiment, both the body 210 and the clamping part of the connector 200 are insulating components, thus meeting safety regulations. Furthermore, the insulating clamping part prevents scratches on the second circuit board 300, extending its service life. The soldering pins 270 are metal components, such as copper or aluminum. The body 210, clamping part, and soldering pins 270 are integrally formed by injection molding. This injection molding process not only ensures high production efficiency but also allows for the design of connectors 200 of different sizes to meet the clamping requirements of circuit boards of varying sizes.

[0058] Please continue to refer to Figure 4 and Figure 5In this embodiment, the first circuit board 100 is provided with at least one slot 120, and the second circuit board 300 is provided with at least one protrusion 310 and at least one recess 320. The protrusion 310 is inserted into the slot 120 to realize the connection between the first circuit board 100 and the second circuit board 300. The connector 200 is disposed in the recess 320, which can be disposed on the part of the second circuit board 300 where no electronic components are installed, thereby making full use of space.

[0059] This embodiment also provides an electronic device, including the circuit board assembly described above.

[0060] Specifically, the electronic device in this embodiment may include, for example, a frequency converter. Based on the need for miniaturization, the electronic device in this embodiment uses a board-to-board method to vertically connect the first and second circuit boards. Due to the use of the aforementioned circuit board assembly, the electronic device in this embodiment can ensure a high degree of perpendicularity between the first and second circuit boards, thereby ensuring the normal operation of the electronic device.
