[0041] As described in the background technology, in the related art, due to the space limitation in the chassis of the network device, the bending radius of the cable at the tail of the adapter card is small, which causes a certain force to be applied to the tail of the adapter card. When the fan and hard disk are running at high speed, high-frequency vibration will be generated, causing one end of the adapter card to tilt or move upward, which will cause poor contact between the adapter card and the board, data transmission errors or reduced transmission rate, causing the network device to fail to operate normally.

[0042] In view of this, the board-card fixing device and the board-card assembly provided in the embodiment of the present application. The board-card assembly includes a board-card, an adapter card and a board-card fixing device. The adapter card and the board-card fixing device are both plugged into the board-card, and the board-card fixing device is used to fix the adapter card. Among them, a card slot is provided on the board-card, and the card slot is located on one side of the adapter card. The board-card fixing device includes a main body, a buckle part and a fixing part, the buckle part is connected to the bottom end of the main body, the fixing part is connected to the main body, and the main body is connected to the buckle part and the fixing part as a whole. The board-card fixing device relies on its buckle part to be inserted into the card slot of the board-card, so that its main body is located on one side of the adapter card, and the fixing part connected to the main body is abutted against the top of the adapter card, and the pressure applied to the adapter card by the fixing part prevents one end of the adapter card from tilting or moving upward as a whole, ensuring that the adapter card is in good contact with the board-card, avoiding problems in data transmission, and improving the reliability of network equipment operation.

[0043] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of this application.

[0044] Figure 1This is a structural diagram of the board assembly provided in the embodiment of the present application. Figure 1 As shown, the embodiment of the present application provides a board assembly 1, which is mainly installed in a chassis of a network device. The network device may include a computer, a server, a switch, an industrial computer, etc. The board assembly 1 is a core component of the network device.

[0045] The board assembly 1 includes a board fixture 10, a board 20 and an adapter card 30. The board fixture 10, the board 20 and the adapter card 30 can exist independently of each other, or can be assembled into one.

[0046] The board 20 is usually fixed in the chassis of the network device. The board 20 is usually equipped with a central processing unit, a memory, and a storage interface and a hard disk interface for communication. The board 20 is the basis for ensuring the normal operation of the central processing unit and the memory.

[0047] Figure 2 for Figure 1 Refer to the structural diagram of the board in Figure 2 As shown, a card slot 210 is provided on the board 20. The card slot 210 is used to limit the board fixing device 10. The exemplary card slot 210 is a slot-shaped structure with a narrow slot opening and a wide slot body. Alternatively, the shape of the card slot 210 can be a square hole, a rectangular hole, or a stepped hole with an opening facing downward.

[0048] The board 20 is provided with a plug-in slot 220 , and a circuit line is provided between the plug-in slot 220 and the central processing unit and the memory.

[0049] The board 20 may be provided with a plurality of plug-in slots 220 according to the extended function items, and the plurality of plug-in slots 220 may be arranged in parallel. The card slot 210 is provided corresponding to the plug-in slot 220 , and the card slot 210 is provided on one side of the plug-in slot 220 .

[0050] The adapter card 30 may be an expansion card of a network device, used to expand the functions of the network device. The adapter card 30 is plugged into the board 20 through the plug slot 220. The adapter card 30 is provided with a circuit path and electronic components. Exemplarily, the adapter card 30 may be a high-speed serial expansion card (Peripheral Component Interconnect Express Card, referred to as PCIE card), used to increase the data transmission rate, thereby enhancing the performance of the device.

[0051] The adapter card 30 includes a gold finger component, which is usually composed of many golden conductive contacts and is used for communication. The adapter card 30 is plugged into the plug slot 220 of the board 20 through the gold finger. The adapter card 30 can exchange information with the central processor and memory of the board 20 through the plug slot 220 to achieve the expansion of network device functions. At the same time, the friction between the gold finger and the plug slot 220 can fix the adapter card 30 to a certain extent.

[0052] When the network device is working, the fan and hard disk in the chassis will generate high-frequency vibration, which can easily cause the board 20 to tilt or move upward. In the embodiment of the present application, the board fixing device 10 is used to fix the adapter card 30.

[0053] Figure 3 for Figure 1 The structural diagram of the board fixing device in FIG. Figure 3 As shown, the board card fixing device 10 includes a main body 110, a buckle part 120 and a fixing part 130. The buckle part 120 is connected to the bottom end of the main body 110. The fixing part 130 is connected to the main body 110, for example, the fixing part 130 is located at the upper part of the main body 110.

[0054] The main body 110 is the main body of the board fixing device 10, and provides support for the board fixing device 10. The end of the main body 110 facing the board is the bottom end, and the end of the main body facing away from the board is the top end.

[0055] The buckle portion 120 can be plugged into the card slot 210 through its own elastic deformation, and the buckle portion 120 is clamped in the card slot 210. When the buckle portion 120 is inserted into the board card 20, no other locking accessories are required, which can save the use cost.

[0056] The buckle portion 120 can be removed from the card slot 210, which facilitates the maintenance and replacement of the board card fixing device 10 after it is damaged.

[0057] The buckle portion 120 is inserted into the card slot 210. As mentioned above, the card slot 210 is arranged on one side of the plug-in slot 220. The buckle portion 120 plugged into the card slot 210 is located on one side of the adapter card 30 plugged into the plug-in slot 220. The buckle portion 120 is connected to the bottom end of the main body 110, and the main body 110 is located on one side of the adapter card 30. There is a certain distance between the main body 110 and the adapter card 30. This arrangement prevents the main body 110 from hitting the electrical components on the adapter card 30, causing damage to the adapter card 30 and causing the adapter card 30 to fail to work normally.

[0058] By inserting the buckle part 120 into the card slot 210, the main body 110 is restricted from moving, and the fixing part 130 is connected to the main body 110, and the fixing part 130 is also restricted from moving. The fixing part 130 abuts against the top of the adapter card 30, and the adapter card 30 and the fixing part 130 generate an interaction force. The adapter card 30 is subjected to the downward force generated by the fixing part 130, so that the adapter card 30 cannot be tilted or moved upward. In this way, the poor contact between the adapter card 30 and the plug-in slot 220 can be prevented, the normal operation of the network device can be ensured, and the stability of the operation of the network device can be improved.

[0059] Exemplarily, the board and card fixing device 10 can be an integrally formed part, in other words, the buckle portion 120 and the fixing portion 130 can be integrally formed on the main body 110. For example, the board and card fixing device 10 can be made of elastic plastic material using a one-time injection molding process. In this way, the board and card fixing device 10 has the characteristics of high strength and good elasticity. The board and card fixing device 10 can also be mass-produced with high processing efficiency.

[0060] When assembling the adapter card 30 and the board fixing device 10 on the board 20, in a first embodiment, the adapter card 30 is first inserted into the plug-in slot 220 of the board 20; then, it is inserted into the card slot 210 of the board 20 through the buckle portion 120, and the main body 110 connected to the buckle portion 120 is restricted from moving; the fixing portion 130 connected to the main body 110 is also restricted from moving, and the fixing portion 130 abuts against the top of the adapter card 30 to restrict the adapter card 30 from tilting or moving upward, thereby ensuring that the adapter card 30 is in good contact with the plug-in slot 220 and ensuring the normal operation of the network device.

[0061] In the second embodiment, the buckle portion 120 is inserted into the card slot 210 of the board 20, the main body portion 110 connected to the buckle portion 120 is restricted from moving, and then the fixing portion 130 connected to the main body portion 110 is restricted from moving; then, a force is applied to the top of the main body portion 110 away from the adapter card 30, the main body portion 110 is bent in an arc around the bottom of the main body portion 110, the top of the main body portion 110 is away from the position of the adapter card 30, and the main body portion 110 drives the fixing portion 130 away from the position of the adapter card 30; then the adapter card 30 is inserted into the plug-in slot 220 of the board 20; then the force applied to the top of the main body portion 110 is removed, and the top of the main body portion 110 drives the fixing portion 130 to return to its original position; the fixing portion 130 abuts against the top of the adapter card 30, restricting the adapter card 30 from tilting or moving upward, ensuring good contact between the adapter card 30 and the plug-in slot 220, and ensuring the normal operation of the network device.

[0062] The following description will take the assembly method of the board fixing device 10 and the adapter card 30 as a second embodiment.

[0063] Reference Figure 3 As shown, the main body 110 extends with a connecting portion 140, and the connecting portion 140 is located on a side surface of the main body 110 facing the adapter card 30. As mentioned above, the main body 110 is located on one side of the adapter card 30, and there is a certain distance between the main body 110 and the adapter card 30, and the fixing portion 130 abuts against the top of the adapter card 30, and the connecting portion 140 is arranged between the main body 110 and the fixing portion 130.

[0064] The connecting portion 140 can be arranged close to the top of the main body 110 and away from the buckle portion 120. The connecting portion 140 is connected to the fixing portion 130, and the fixing portion 130 abuts against the top of the adapter card 30. The buckle portion 120 can be regarded as a fulcrum, and the distance between the top of the main body 110 and the buckle portion 120 is a lever arm. When the distance between the top of the main body 110 and the buckle portion 120 is large, when the connecting portion 140 has the same length, the greater the force applied to the adapter card 30, the better the effect of preventing the adapter card 30 from tilting or moving upward.

[0065] The connecting portion 140 extends from the side of the main body 110 facing the adapter card 30. On the basis of connecting the fixing portion 130 to the other end of the connecting portion 140, the extending direction of the connecting portion 140 can be inclined toward the top of the main body 110. The connecting portion 140 extends upward from the main body 110 at an angle, and the height of the main body 110 does not need to be set too high, which can increase the space above the main body 110 and save the material of the board and card fixing device 10. In addition, when the fixing portion 130 abuts against the top of the adapter card 30, the connecting portion 140 is subjected to the force of the fixing portion 130 and produces a certain deformation. By making the connecting portion 140 extend upward at an angle, the deformation of the connecting portion 140 can be reduced, the tearing of the connecting portion 140 can be avoided, and the service life of the board and card fixing device 10 can be extended.

[0066] The fixing portion 130 may be provided with a groove structure, the top surface of the groove abuts against the top of the adapter card 30, and providing the groove can save materials. Exemplarily, the groove may be L-shaped, that is, the groove has a top surface and a side surface, and the side surface of the groove away from the main body 110 does not exist.

[0067] The side corners of the groove are all chamfered to prevent the fixing portion 130 from hitting the electronic components on the adapter card 30 when the adapter card 30 is installed, thereby preventing the adapter card 30 from failing.

[0068] Figure 4 for Figure 3 Front view of the board holder in . Figure 4As shown, the buckle portion 120 of the board card fixing device may include a support portion 121 and an elastic portion 122. The support portion 121 may extend downward along the center line of the main body 110, the top of the support portion 121 is connected to the bottom of the main body 110, and the elastic portion 122 is symmetrically connected to both sides of the support portion 121.

[0069] The support portion 121 is the skeleton of the buckle portion 120 and provides support for the buckle portion 120. The support portion 121 can be configured as a plate-like body with a certain thickness, and the support portion 121 has a certain strength and rigidity.

[0070] The bottom end of the elastic part 122 is connected to the supporting part 121. The elastic part 122 is a structure with elastic deformation, and the buckle part 120 is inserted into the slot 210 through the elastic deformation of the elastic part 122. Exemplarily, the elastic part 122 may be V-shaped or U-shaped.

[0071] The top ends of both sides of the elastic part 122 extend in a direction away from the support part 121. The top wall of the elastic part 122 abuts against the card slot 210. By applying a force toward the support part 121 on both sides of the elastic part 122, the elastic part 122 is compressed and deformed and inserted into the card slot 210. After the force on the elastic part 122 is removed, the elastic part 122 rebounds and abuts against the card slot 210, and the elastic part 122 is stuck in the card slot 210. Exemplarily, the card slot 210 is a slot-shaped structure with a narrow slot opening and a wide slot body. When the elastic part 122 is inserted into the card slot 210, the elastic part 122 is restricted by the slot body of the card slot 210 to move forward and backward and left and right after rebounding, and the elastic part 122 is restricted by the slot opening and the slot bottom of the card slot 210 to move up and down, thereby restricting the movement of the board fixing device 10. The fixing portion 130 of the board fixing device 10 abuts against the top surface of the adapter card 30 , restricting the adapter card 30 from tilting or moving upward, thereby ensuring good contact between the adapter card 30 and the insertion slot 220 .

[0072] It should be noted that the elastic portion 122 tends to deform toward the two sides away from the support portion 121. The deformation of the elastic portion 122 may cause the buckle portion 120 to fail. In order to prevent the buckle portion 120 from failing and escaping from the card slot 210, in some embodiments, the top wall of the elastic portion 122 may be further provided with a baffle portion 1221. There is a gap between the baffle portion 1221 and the end of the top wall of the elastic portion 122 away from the support portion 121.

[0073] For ease of explanation, in this embodiment, an end of the top wall of the elastic portion close to the support portion 121 is defined as the first end of the top wall of the elastic portion, and an end of the top wall of the elastic portion 122 away from the support portion 121 is defined as the second end of the top wall of the elastic portion 122.

[0074] By providing a baffle portion 1221 on the top wall of the elastic portion 122, a distance is provided between the baffle portion 1221 and the second end of the top wall of the elastic portion 122. For example, the baffle portion 1221 may be flush with the first end of the top wall of the elastic portion 122. When the buckle portion 120 is inserted into the card slot 210, the top wall of the elastic portion 122 (the portion not covered by the baffle portion) abuts against the inner top wall of the card slot 210. The baffle portion 1221 abuts against the edge of the notch of the card slot 210. In other words, the side of the baffle portion 1221 abuts against the side of the notch of the card slot 210. The baffle portion 1221 limits the deformation of the elastic portion 122 to both sides, which can prevent the buckle portion 120 from failing.

[0075] Figure 5 for Figure 3 Rear view of the board retainer in the . Figure 3 and Figure 5 As shown, in one embodiment, a groove 111 is provided on the outer side of the main body 110 that is opposite to or opposite to the adapter card 30. The groove 111 extends along the width direction of the main body 110, and the groove 111 extends to the other two outer sides of the plug slot 220. When a force is applied to the top of the main body 110 away from the adapter card 30, the thickness of the groove 111 of the main body 110 is small and the deformation is large. The bending amplitude of the upper part of the main body 110 located in the groove 111 is large, and the bending amplitude of the lower part of the main body 110 located in the groove 111 is small. The acting force between the buckle part 120 below the main body 110 and the card slot 210 is small, and the acting force on the buckle part 120 is small, so that the buckle part 120 is prevented from being ineffective due to excessive force.

[0076] The groove 111 is disposed on the side of the adapter card 30 that the main body 110 is away from. When a force is applied to the top of the main body 110 that is away from the adapter card 30, the main body 110 bends in the direction away from the adapter card 30, and at this time, the groove 111 is squeezed. If the groove 111 is disposed on the side of the main body 110 that is opposite to the adapter card 30, the groove 111 is stretched. Under the same conditions, the groove 111 is more likely to break when stretched than when compressed. The groove 111 is disposed on the side of the adapter card 30 that the main body 110 is away from, and such a configuration can improve the reliability of the board fixing device 10.

[0077] The groove 111 is arranged near the middle of the main body 110, and there is a certain distance between the groove 111 and the buckle part 120. In this way, the buckle part 120 is subjected to a smaller force when the main body 110 is bent, and the buckle part 120 has a higher reliability.

[0078] Reference Figure 5As shown, a limiting portion 112 is disposed at the bottom end of the main body 110, and both ends of the limiting portion 112 extend beyond both sides of the main body 110, and both ends of the limiting portion 112 are disposed against the surface of the board 20. The limiting portion 112 can be configured to be symmetrical on both sides. The limiting portion 112 limits the board fixing device 10 from moving downward.

[0079] In one embodiment, the elastic portion 122 passes through the card slot 210, the top wall of the elastic portion 122 abuts against the board card 20, the elastic portion 122 limits the upward movement of the board card fixing device 10, and the baffle portion 1221 limits the front-back and left-right movement of the board card fixing device 10. At this time, the limiting portion 112 can limit the downward movement of the board card fixing device 10. The board card fixing device 10 is restricted from moving, ensuring that the board card fixing device 10 abuts against the top of the adapter card 30, and ensuring that the fixing portion 130 abuts against the top of the adapter card 30.

[0080] The limiting portion 112 may include an arc-shaped elastic portion 1121 . The arc-shaped elastic portion 1121 is curved in an arc shape. The inner side of the arc-shaped elastic portion 1121 faces the board 20 . Both ends of the arc-shaped elastic portion 1121 are disposed against the surface of the board 20 .

[0081] There are processing errors in the board and card fixture 10, and there are assembly errors between the board and card fixture 10, the board 20, and the adapter card 30. The processing errors and assembly errors will cause the board and card fixture 10 to be unable to abut against the top of the adapter card 30, causing the board and card fixture 10 to lose its function. The arc-shaped elastic portion 1121 can deform to compensate for the processing errors and assembly errors, ensuring that the board and card fixture 10 does not loosen during use and ensuring that the adapter card 30 is in good contact with the plug-in slot 220.

[0082] Limiting part pressure feet 1122 can also be set at both ends of the arc-shaped elastic part 1121, and the limiting part pressure feet 1122 abut against the surface of the board 20. The limiting part pressure feet 1122 can be set as cylindrical surfaces. The limiting part pressure feet 1122 abut against the board 20 smoothly, which can reduce the stress concentration phenomenon of the board 20 and prevent the board 20 from being scratched or causing local fracturing of the board 20.

[0083] A limit rib plate 1123 is disposed above the arc-shaped elastic portion 1121 and is connected to the main body 110. The limit rib plate 1123 is symmetrically disposed front and back and left and right. The limit rib plate 1123 can enhance the elastic force of the arc-shaped elastic portion 1121.

[0084] Figure 6 for Figure 3 Side view of the board holder in Figure 1. Figure 5 and Figure 6As shown, a handle portion 150 is provided at the top of the main body 110, and the maximum thickness of the handle portion 150 is greater than the thickness of the main body 110. The handle portion 150 can make the user have a relaxing experience when applying force at the top of the main body 110.

[0085] The handle portion 150 may be cylindrical with a smooth surface. The handle portion 150 may be symmetrically arranged or offset with respect to the center of the main body portion 110. For example, the outer cylindrical surface of the handle portion 150 may be tangent to the outer surface of the main body portion 110 near the adapter card 30, so that there is enough operating space for fingers during operation.

[0086] The side of the main body 110 facing away from the adapter card 30 is provided with an anti-skid protrusion 113, which is located below the handle 150. The thumb is placed on the handle 150, and the other finger is placed on the anti-skid protrusion 113. This makes it easier to apply force and more comfortable to operate.
