[0029] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Taking the Peripheral Component Interconnect Express (PCIe) connector as an example, with the improvement of graphics card performance in PCI, the size and weight of graphics cards have become larger and heavier. Furthermore, starting with PCIe 5.0, the PCIe x16 connector used on the motherboard can only be implemented using surface mount technology (SMT), resulting in relatively weaker board grip strength. This leads to problems such as broken keying protrusions, cracked or detached pins; and the increased size of the graphics card obstructing the connector's tail clips, making it inconvenient to remove and reassemble the graphics card.

[0031] To address the aforementioned issues, a metal clamp can be added to the key to increase its strength. However, this method has limitations because the key width is only 1.8mm, limiting the amount of metal that can be added, thus limiting the strength of the key. When using heavier graphics cards, key breakage can still occur. Another approach is to add an extra metal shell around the connector, enclosing it and adding welded metal feet and a more stable graphics card retainer for locking. However, this method increases the connector's specifications, resulting in low standardization. Assembling different graphics card retainers outside the graphics card structure also increases costs due to the additional connector locking structure.

[0032] This application provides a connector fixing structure, including a frame and a pressing component. The frame is connected to the connector on the motherboard, and the pressing component is used to cooperate with the tail buckle of the connector to realize the pressing operation of the tail buckle. The pressing component is provided with an extension, which extends outward by a certain distance to avoid being covered by larger hardware, thus ensuring that the pressing component and the tail buckle are triggered.

[0033] The following description, in conjunction with the accompanying drawings, details the components of the connector fixing structure provided in the embodiments of this application, the positional relationships between the components, and the connection relationships.

[0034] like Figures 1 to 4 As shown in this embodiment, the frame 10 is used to connect to the motherboard 40. The frame 10 includes a clearance hole 11, which is used to accommodate the tail buckle 60 of the connector 50. The pressing assembly 20 includes a pressing buckle 21 and a connecting spring arm 22. One end of the connecting spring arm 22 is connected to the pressing buckle 21, and the other end of the connecting spring arm 22 is connected to the frame 10. The pressing buckle 21 is located above the clearance hole 11, and the pressing buckle 21 includes an extension 23, which is used to extend beyond the coverage area of ​​the hardware connected to the connector 50.

[0035] A tail buckle 60 is provided at the edge of the connector 50. When the connector 50 is not connected to hardware, the tail buckle 60 is in the open state. After the hardware is connected, the tail buckle 60 locks the plug end 24 of the hardware. In this embodiment, a frame structure 10 is additionally provided on the outside of the tail buckle 60. A pressing component 20 is provided on the frame structure 10. By operating the pressing component 20, the tail buckle 60 can be pressed.

[0036] The clearance hole 11 of the frame 10 provides movement space for the tail buckle 60 and the pressing assembly 20. After the hardware is installed, the tail buckle 60 is in the fastened state, and when not under force, such as Figure 1 In the state shown, the snap fastener 21 is held in the reset position via the connecting spring arm 22. At this time, there is no relative force between the snap fastener 21 and the tail buckle 60; they remain in a closed position or with a certain gap. When force is applied, such as... Figure 6In the indicated state, the press buckle 21 moves to the press position against the elastic force of the connecting spring arm 22. When in the press position, the press buckle 21 triggers the tail buckle 60 in the clearance hole 11. That is, as force is applied to the press buckle 21, the connecting spring arm 22 deforms, causing the press buckle 21 to contact the tail buckle 60. The force of the press buckle 21 acts on the tail buckle 60, and finally, by pressing the tail buckle 60, the tail buckle 60 is opened, ejecting the hardware connected to the connector 50.

[0037] In this embodiment of the application, one end of the housing 12 is provided with a connecting frame 15, and a clearance hole 11 is provided on the connecting frame 15; the surface of the connecting frame 15 is provided with a slot 16, and the other end of the connecting spring arm 22 is provided with a plug-in end 24, which is plugged into the slot 16.

[0038] For example, a snap-fit ​​end perpendicular to the plane of the connecting spring arm 22 is provided on the insertion end 24 of the connecting spring arm 22, and a corresponding receiving groove is provided on the slot 16 to snap into the snap-fit ​​end, so that the insertion end 24 can be stably connected to the slot 16.

[0039] For example, the pressing assembly 20 includes two connecting spring arms 22, which are spaced apart to create clearance between the connector 50 and the tail buckle 60. The two connecting spring arms 22 can provide a stable connection with the connecting frame 15, ensuring that when force is applied to the pressing buckle 21, the connecting spring arms 22 can maintain a stable connection with the connecting frame 15.

[0040] For example, in this embodiment, the extension 23 extends along the width direction of the housing 12. For example, the hardware is a graphics card. Different models of graphics cards have different external dimensions, and the variation range of each model in the width direction is relatively small. Therefore, by extending the extension 23 along the width direction of the housing 12, it is ensured that when connecting different models of graphics cards, at least part of the extension 23 is outside the graphics card so that the pressing operation can be completed.

[0041] Continue to refer to Figure 1 and Figure 3 As shown in the embodiment of this application, the frame 10 also includes a housing 12, which is located on one side of the connecting frame 15 / avoidance hole 11. The housing 12 is used to cover the connector 50. The housing 12 includes an opening 13 that is opposite to the insertion interface of the connector 50. The opening 13 is provided with anti-collision ribs 14. When the housing 12 is connected to the connector 50, the anti-collision ribs 14 are superimposed on the connector anti-fooling protrusion.

[0042] The anti-collision rib 14 is located on the outside of the connector anti-fooling protrusion. During hardware insertion, if the hardware comes into contact with this part of the structure, the insertion end 24 of the hardware will contact the anti-collision rib 14, thus avoiding contact with the connector anti-fooling protrusion. The anti-collision rib 14 protects the connector anti-fooling protrusion and prevents the connector anti-fooling protrusion from breaking due to insertion.

[0043] For example, the width of the anti-collision rib 14 is the same as or slightly wider than the width of the connector's anti-fooling protrusion, which can effectively prevent the connector's anti-fooling protrusion from contacting the hardware's insertion end 24. For example, the anti-collision rib 14 and the housing 12 are integrally molded structures. When manufacturing the housing 12, the anti-collision rib 14 is integrally molded simultaneously to ensure the connection strength between the anti-collision rib 14 and the housing 12.

[0044] Continue to refer to Figure 1 and Figure 5 As shown in the embodiment of this application, the connector fixing structure further includes a back plate 30, which is disposed on the side of the main board 40 away from the frame 10, and is used to fix the main board 40 and / or the frame 10.

[0045] When the backplate 30 is installed in a flat shape, the backplate 30 is attached to the connected motherboard 40. The backplate 30 can be provided with mounting holes 31, the motherboard 40 can be provided with through holes communicating with the mounting holes 31, and the frame 10 can be provided with screw holes. The mounting screws pass through the mounting holes 31 and the through holes and are fastened to the screw holes; or, the backplate 30 and the frame 10 can be fixedly connected to the motherboard 40 respectively.

[0046] This application provides a motherboard 40, including the connector fixing structure described above. This application also provides an electronic product, including the connector fixing structure described above or including the motherboard 40 described above.

[0047] The backplate 30 and the frame 10 work together to clamp and fix the connector 50 on the motherboard 40. In the event of a drop impact, the connector fixing structure can provide clamping force to protect the strength of the solder feet of the connector 50 and prevent solder cracking and desoldering.

[0048] The anti-collision rib 14 protects the connector's anti-fooling protrusion. During insertion, it prevents the force from acting directly on the connector's anti-fooling protrusion. In the event of an impact or drop, the inertial force of the hardware acts on the anti-collision rib 14. The anti-collision rib 14 is strong enough to prevent the impact of the graphics card insertion end 24 from acting directly on the connector 50 and to prevent the connector's anti-fooling protrusion from breaking due to impact.

[0049] When disassembling the hardware, press the extension 23 for easy pressing. The extension 23 can prevent the hardware from being completely blocked due to changes in hardware size, ensuring that the tail buckle 60 of the hardware can be triggered normally, thus making the connector fixing structure more versatile.

[0050] This application provides a connector fixing structure, a motherboard 40, and an electronic product. A frame 10 and a pressing component 20 are provided outside the connector 50 on the motherboard 40. The tail latch 60 of the connector 50 can be triggered by pressing the pressing latch 21. When the size of the hardware connected to the connector 50 is too large, the tail latch 60 of the connector 50 can be triggered by triggering the extension 23. In this technical solution, the connector fixing structure is located at the connector 50, protecting the connector 50 and providing structural reinforcement, eliminating the need for a separate retainer. Furthermore, the extension 23 of the pressing latch 21 extends beyond the connected hardware, facilitating disassembly and assembly.
