[0030] The utility model provides a circuit board assembly 100. Figures 1 to 3 , Figure 1 This is a schematic structural diagram of an embodiment of a circuit board assembly 100 of the utility model; Figure 2 This is a schematic diagram of the exploded structure of an embodiment of a circuit board assembly 100 of the present utility model; Figure 3 It is a structural schematic diagram of an embodiment of a grounding member 30 of the present utility model.

[0031] In the embodiment of the present utility model, Figures 1 to 3 As shown, the circuit board assembly 100 proposed by the utility model includes:

[0032] A first circuit board 10;

[0033] A second circuit board 20, wherein the second circuit board 20 is provided with a positioning hole 21; and

[0034] A grounding member 30 is connected to the first circuit board 10 and is provided with a grounding structure 31. The grounding structure 31 is provided with a positioning foot 32 protruding toward the direction of the second circuit board 20. The positioning foot 32 is inserted into the positioning hole 21 to connect the grounding member 30 to the second circuit board 20.

[0035] Specifically, the positioning pin 32 is used to be inserted into the positioning hole 21, so that the grounding structure 31 is connected to the second circuit board 20. The first circuit board 10 and the second circuit board 20 are connected through the grounding member 30, and the second circuit board 20 is grounded. The first circuit board 10 is connected to the second circuit board 20 through the grounding member 30, and then the grounding discharge can be conducted to achieve the grounding effect.

[0036] Because the grounding member 30 on the existing circuit board assembly 100 is easily misaligned with the through hole 22 on the circuit board when it is installed on the circuit board using screws, it is necessary to repeatedly move the position of the grounding member 30 in order to align the mounting hole 310 on the grounding member 30 with the through hole 22 on the circuit board, thereby resulting in low installation efficiency.

[0037] The utility model provides a positioning foot 32 on the grounding member 30. When the grounding member 30 needs to be installed on the second circuit board 20, the positioning foot 32 is directly inserted into the positioning hole 21 on the second circuit board 20, thereby ensuring that the installation position is not deviated and improving the installation efficiency; and in the subsequent locking process, the grounding member 30 is positioned on the second circuit board 20 by the positioning foot 32, and is not easy to rotate with the tightening of the fastener 40, so as to avoid the situation where the grounding member 30 rotates and scratches the assembler.

[0038] In one embodiment, the grounding member 30 may be a connecting wire, one end of which is welded to the first circuit board 10, and the other end of which is connected to the second circuit board 20 via the positioning pin 32. The first circuit board 10 is connected to the second circuit board 20 via the connecting wire to achieve a grounding effect.

[0039] Among them, the grounding member 30 can also be a metal pin structure, one end of which is connected to the first circuit board 10, and the other end is provided with a grounding structure 31 to be plugged into the second circuit board 20, so that the first circuit board 10 is connected and conductive with the second circuit board 20 through the metal pin structure.

[0040] The technical solution of the utility model is to set a positioning hole 21 on the second circuit board 20, and set a grounding structure 31 at one end of the grounding piece 30 close to the second circuit board 20, and the grounding structure 31 is provided with a positioning foot 32 protruding toward the direction of the second circuit board 20, one end of the grounding piece 30 is connected to the first circuit board 10, and the other end is inserted into the positioning hole 21 through the positioning foot 32, so that the grounding piece 30 is connected to the second circuit board 20, and the assembly operation of the grounding piece 30 and the second circuit board 20 is simple and fast, and the installation position is accurate; and in the subsequent locking process, the grounding piece 30 is positioned on the second circuit board 20 by the positioning foot 32, and is not easy to rotate with the twisting of the fastener 40, thereby avoiding the situation where the grounding piece 30 rotates and scratches the assembler.

[0041] like Figure 2 and Figure 3As shown, in order to facilitate the insertion of the positioning pin 32 into the positioning hole 21 on the second circuit board 20, the positioning pin 32 includes a fixing portion 321 and a limiting pin 322, the fixing portion 321 is arranged at the edge of the grounding structure 31, the limiting pin 322 is extended in the direction of the positioning hole 21, and the limiting pin 322 is inserted in the positioning hole 21.

[0042] In one embodiment, the limiting foot 322 is bent relative to the fixing portion 321 and extends toward the second circuit board 20, so that the positioning foot 32 can be inserted into the positioning hole 21 on the second circuit board 20 through the limiting foot 322. When the limiting foot 322 is inserted into the positioning hole 21, the grounding structure 31 is limited on the second circuit board 20, thereby connecting the grounding member 30 to the second circuit board 20.

[0043] like Figure 2 and Figure 3 As shown, in order to prevent the second circuit board 20 from escaping from the positioning foot 32, the limiting foot 322 is provided with a locking portion 323, and the locking portion 323 is bent. A positioning space 324 is provided between the locking portion 323 and the fixing portion 321, and the second circuit board 20 is limited in the positioning space 324.

[0044] In one embodiment, the second circuit board 20 is plugged into the limiting foot 322 of the grounding structure 31, and the second circuit board 20 is located in the positioning space 324. The locking portion 323 of the positioning foot 32 can be bent away from the center of the grounding structure 31 or bend toward the center of the grounding structure 31. The bent locking portion 323 can prevent the second circuit board 20 from falling off the limiting foot 322. The appearance of the locking portion 323 can be set to be an arc or an L-shaped bending part.

[0045] In order to stably fix the second circuit board 20 on the grounding member 30 , the number of the positioning pins 32 is at least two, the two positioning pins 32 are arranged opposite to the grounding structure 31 , and the positioning holes 21 are arranged one-to-one with the positioning pins 32 .

[0046] In one embodiment, positioning pins 32 are provided on two opposite sides of the grounding structure 31, and the two positioning pins 32 can be plugged into the second circuit board 20. The two positioning pins 32 are provided with a locking portion 323 to ensure that the second circuit board 20 is stably fixed on the bottom of the grounding structure 31.

[0047] The number of the positioning pins 32 may be three, four or six. The positioning pins 32 are arranged at the outer edge of the grounding structure 31. The positioning pins 32 may be provided with a locking portion 323 to limit the second circuit board 20 to the grounding structure 31 and prevent it from falling.

[0048] In order to ensure the installation stability of the grounding structure 31 of the grounding member 30 and the second circuit board 20, the circuit board assembly 100 also includes a fastener 40, the grounding structure 31 is provided with a mounting hole 310, and the second circuit board 20 is provided with a through hole 22. The fastener 40 passes through the mounting hole 310 and the through hole 22 and is connected to the second circuit board 20.

[0049] In order to firmly fix the grounding structure 31 of the grounding member 30 on the second circuit board 20, the circuit board assembly 100 further includes a fastener 40, which is used to lock the grounding structure 31 of the grounding member 30 on the second circuit board 20. Specifically, after the grounding member 30 is inserted into the positioning hole 21 of the second circuit board 20 through the positioning pin 32, the fastener 40 passes through the mounting hole 310 and the through hole 22, and is connected to the second circuit board 20. The fastener 40 presses the grounding structure 31, so that the grounding member 30 is firmly fixed on the second circuit board 20, thereby ensuring the installation stability of the grounding structure 31 of the grounding member 30 and the second circuit board 20.

[0050] In one embodiment, the fastener 40 is a screw, which has conductive properties, and can connect the grounding structure 31 of the grounding member 30 to the second circuit board 20. The screw rod of the screw passes through the mounting hole 310 and the through hole 22, and is connected to the second circuit board 20. The nut of the screw presses the grounding structure 31, so that the grounding member 30 is firmly fixed on the second circuit board 20.

[0051] like Figure 1 and Figure 2 As shown, the circuit board assembly 100 further includes a locking member 50 , which is located on a side of the second circuit board 20 away from the grounding member 30 , and the fastener 40 passes through the through hole 22 and is connected to the locking member 50 .

[0052] In one embodiment, the locking member 50 is located at the bottom of the second circuit board 20, the fastener 40 passes through the mounting hole 310 and the through hole 22 in sequence, and is connected to the locking member 50, and the locking member 50 and the fastener 40 together clamp the grounding structure 31 and the second circuit board 20, so that the grounding structure 31 of the grounding member 30 is firmly connected with the second circuit board 20. Since the grounding member 30 is provided with a positioning foot 32, the positioning foot 32 is plugged into the positioning hole 21 of the second circuit board 20, and the positioning foot 32 can play a positioning role. In the process of locking the fastener 40 and the locking member 50, the grounding member 30 is positioned on the second circuit board 20 by the positioning foot 32, and is not easy to rotate with the twisting of the fastener 40, thereby preventing the grounding member 30 from rotating and scratching the assembler.

[0053] like Figure 2 As shown, in order to be able to lock with the fastener 40 and support the second circuit board 20, the locking member 50 is provided with a mounting tube 51, the fastener 40 passes through the through hole 22 and is mounted on the mounting tube 51, and the mounting tube 51 supports the second circuit board 20.

[0055] In order to ensure that the positioning pin 32 can be plugged into the positioning hole 21 of the second circuit board 20 , the positioning pin 32 is arranged to avoid the installation tube 51 .

[0056] After the first circuit board 10 is connected to the grounding member 30, when the second circuit board 20 needs to be assembled with the grounding member 30, the second circuit board 20 is first placed on the locking member 50, and then the two positioning legs 32 of the wiring member are inserted into the two positioning holes 21 of the second circuit board 20, and the grounding member 30 is pre-fixed on the second circuit board 20. Afterwards, the fastener 40 is passed through the mounting hole 310 and the through hole 22, and is locked with the mounting tube 51 of the locking member 50, and the first circuit board 10 and the second circuit board 20 are connected and conducted to achieve a grounding effect.

[0057] One end of the grounding member 30 is welded to the first circuit board 10 , so that the grounding member 30 is not easily separated from the first circuit board 10 , thereby ensuring the connection stability between the grounding member 30 and the first circuit board 10 .

[0058] The utility model also proposes an electronic product, which includes a circuit board assembly 100. The specific structure of the circuit board assembly 100 refers to the above embodiment.
