Description

Technical Field

[0001] This utility model relates to the field of PCB board technology, specifically to an anti-shake PCB board. Background Technology

[0002] In existing removable latch structures, there are almost no measures to eliminate gaps; the latches are allowed to wobble freely, with the most common approach being to reduce the gap between the guide groove and the latch. Figure 1 As shown in the image. However, shrinking the size can cause uneven insertion and removal, or even prevent alignment with the internal connector socket, leading to difficulty in insertion and removal. Furthermore, gaps still exist, the only difference being the size of the gap, and wobbling remains. This wobbling can cause poor contact between the PCB board's gold fingers and the connector socket, resulting in signal interruption. Additionally, wobbling can cause internal noises and a poor user experience.

[0003] In addition, there is a shorter-distance insertion / removal structure on the market that does not rely on guide slots. It connects solely to the connector female and the card's gold fingers, but requires screws to secure it at the end of the card. Examples include M.2 interface connectors and PCI-E interface connectors. It requires an open insertion / removal space, such as opening the device casing, and is very inflexible due to the need for screws. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a PCB board that is compact, small in size, easy to install, and highly stable, addressing the aforementioned problems in the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A PCB board with anti-shake feature is provided on both sides of the PCB board with waist-shaped springs. When the PCB board is inserted or removed along the guide groove of the device body, the waist-shaped springs generate elastic deformation in the guide groove to limit the PCB board from shaking in the guide groove.

[0007] As a further improvement of this utility model, the waist-shaped spring includes a connecting part and an arc-shaped spring sheet. The two ends of the spring sheet are respectively connected to the connecting part. Multiple spring sheets form a spindle-shaped hollow structure with a high middle and low ends, and are nested on the side of the PCB board through the connecting part. When the PCB board is inserted or removed along the guide groove of the device body, the spring sheet is deformed by pressure in the guide groove to limit the PCB board from shaking in the guide groove.

[0008] As a further improvement of this utility model, the stroke generated by the spring sheet under pressure is greater than the gap width between the PCB board and the guide groove.

[0009] As a further improvement of this utility model, the connecting part is provided with a notch, so that when the notch is pried open, the waist-shaped spring can be removed or installed on the side of the PCB board.

[0010] As a further improvement of this utility model, the PCB board is provided with a mounting hole on the side, and a guide post is provided on one side of the mounting hole. The connecting part of the waist-shaped spring is nested on the outer periphery of the guide post, and the spring sheet is pressed down and deformed along the guide post in the mounting hole and guide groove.

[0011] As a further improvement of this utility model, both ends of the mounting hole are rounded.

[0012] As a further improvement of this utility model, the waist-shaped springs are symmetrically arranged on both sides of the PCB board.

[0013] As a further improvement of this utility model, the waist-shaped spring is made of beryllium copper.

[0014] Compared with the prior art, the advantages of this utility model are:

[0015] This utility model's anti-shake PCB card uses waist-shaped springs on both sides of the PCB card to eliminate the gap between the PCB card and the guide groove through the elastic deformation of the waist-shaped springs. Then, the gold fingers of the PCB card cooperate with the connector female inside the device body, so that the PCB card forms a double fixed position inside the device body, achieving the purpose of the PCB card being tightly fitted and not shaking, while not affecting the smoothness of insertion and removal.

[0029] Example

[0030] like Figure 2 , Figure 3 and Figure 4As shown, the anti-shaking PCB card of this utility model has waist-shaped springs 300 symmetrically provided on both sides of the PCB card 100 along the insertion and removal direction of the PCB card 100. When the PCB card 100 is inserted and removed along the guide groove 201 of the device body 200, the waist-shaped springs 300 generate elastic deformation in the guide groove 201 to limit the PCB card 100 from shaking in the guide groove 201.

[0031] In this embodiment, waist-shaped springs 300 are provided on both sides of the PCB card plate 100. The elastic deformation of the waist-shaped springs 300 is used to eliminate the gap between the PCB card plate 100 and the guide groove 201. Then, the gold fingers 101 of the PCB card plate 100 cooperate with the connector female 202 inside the device body 200, so that the PCB card plate 100 forms a double fixed position inside the device body 200. This achieves the purpose of the PCB card plate 100 being both tightly fitted and not shaking, and without affecting the smoothness of insertion and removal.

[0032] like Figure 2 and Figure 3 As shown, the PCB board 100 has mounting holes 102 on its side, and a guide post 103 is provided on one side of the mounting hole 102. The connecting part 301 of the waist-shaped spring 300 is nested on the outer periphery of the guide post 103. The spring piece 302 is pressed down and deformed along the guide post 103 within the mounting hole 102 and the guide groove 201. The waist-shaped spring 300 is made of beryllium copper, which has excellent elastic memory. It can be bent and return to its original shape after the external force is removed.

[0033] Furthermore, both ends of the mounting hole 102 are rounded, and the guide post 103 is cylindrical to improve the smoothness of the waist spring 300 under pressure deformation or returning to its original shape. Moreover, the mounting hole 102 and the guide post 103 can also limit the overall deformation of the waist spring 300, preventing the waist spring 300 from shifting and ensuring that the deformation generated by the waist spring 300 can eliminate the gap between the PCB board 100 and the guide groove 201.

[0034] In this embodiment, the specific placement of the waist-shaped spring 300 on the side of the PCB board 100 can be determined based on the length of the guide groove 201. It is basically placed at the beginning end of the guide groove 201, ensuring the waist-shaped spring 300 is completely submerged within the guide groove (e.g., ...). Figure 4(As shown). By designing mounting holes 102 and guide posts 103 at corresponding positions on the side of the PCB board 100, and fixing the waist-shaped spring 300 in a nested manner, it is both stable and easy to implement. In this way, the PCB board 100 forms two fixed positions: one is the tight fit between the gold finger 101 and the connector female 202, and the other is the tight fit between the waist-shaped spring 300 and the guide groove 201. The wobbling of the PCB board 100 is limited, and at the same time, because the waist-shaped spring 300 has good elasticity, it will not affect the smoothness of the insertion and removal of the PCB board 100.

[0035] like Figure 5 , Figure 6 and Figure 7 As shown, the waist-shaped spring 300 includes a connecting part 301 and an arc-shaped spring piece 302. The two ends of the spring piece 302 are connected to the connecting part 301 respectively. Multiple spring pieces 302 form a spindle-shaped hollow structure with a high middle and low ends, and are nested on the guide post 103 on the side of the PCB card 100 through the connecting part 301. When the PCB card 100 is inserted or removed along the guide groove 201 of the device body 200, the spring piece 302 is deformed by pressure in the mounting hole 102 and the guide groove 201 to limit the PCB card 100 from shaking in the guide groove 201.

[0036] Furthermore, the stroke generated by the pressure on the spring 302 is greater than the gap width between the PCB board 100 and the guide groove 201, so as to ensure that the waist spring 300 and the guide groove 201 are in close contact, thereby ensuring the stability of the PCB board 100.

[0037] like Figure 6 As shown, the connecting part 301 has a notch 303. By prying open the notch 303 with a tool, the waist-shaped spring 300 can be easily removed or installed onto the guide post 103 on the side of the PCB board 100. After installing the waist-shaped springs 300 on both sides of the PCB board 100, it is no longer necessary to spend a lot of money to control the precision of each component. Even if there is a slight deviation, the PCB board 100 can be smoothly inserted into the connector female 202 because the waist-shaped spring 300 provides quantitative cushioning, allowing the PCB board 100 sufficient room to move, thus greatly reducing manufacturing costs.

[0038] like Figure 4 , Figure 8 and Figure 9As shown, the PCB board 100, carrying two beryllium copper waist-shaped springs 300 on the left and right, is inserted into the device body 200 along the guide groove 201. The gold fingers 101 and the connector female 202 inside the device body 200 are then mated. The waist-shaped springs 300 at the beginning of the guide groove 201 are fully inserted. Since the waist-shaped springs 300 are surrounded by spring pieces 302, and the downward stroke of the spring pieces 302 is greater than the gap between the PCB board 100 and the guide groove 201, the deformation of the spring pieces 302 completely eliminates the gap. Because there is a waist-shaped spring 300 on each side of the PCB board 100, the gaps in the four directions of the PCB board 100 (up, down, left, and right) are eliminated. Thus, the PCB board 100 will not wobble after insertion.

[0039] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
