Description

Technical Field

[0001] This utility model belongs to the field of bus interface technology, specifically relating to an extended multi-functional bus interface component. Background Technology

[0002] The bus interface is a slot on the motherboard used to connect various expansion cards (such as graphics cards, sound cards, etc.).

[0003] In existing technologies, because these interfaces are typically directly exposed to the outside, dust can enter and accumulate inside these unprotected interfaces when no expansion cards are inserted. Over time, this dust buildup can become severe. When an expansion card is eventually inserted, the dust can cause poor contact between the bus connector and the expansion card, affecting signal transmission and potentially leading to device instability or hardware malfunction. Utility Model Content

[0004] In view of this, the present invention provides an expandable multi-functional bus interface component, the purpose of which is to seal the opening of the bus interface when the bus interface is not connected to the corresponding expansion card, so that external dust is not easy to enter the interface, thereby improving the sealing performance of the bus interface and reducing the amount of dust accumulation inside the interface.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An expandable multi-functional bus interface assembly includes a slot, the top of which has an opening for inserting a bus connector, and further includes:

[0007] A cover plate, which is disposed inside the opening of the slot to cover the opening of the slot;

[0008] A positioning block, wherein the positioning block is disposed at one end along the length of the slot;

[0009] A storage layer, which is located on the side of the positioning block facing the slot, is used to store the cover plate.

[0010] As a preferred technical solution, the end of the cover away from the spring is provided with a lever, wherein the lever is vertically arranged on the top of the cover.

[0011] Furthermore, the surface of the lever is provided with a clamping groove, which is used to clamp the side of the bus connector.

[0012] Furthermore, guide plates are provided on both sides of the shield, and guide grooves are provided on the inner walls on both sides of the slot, wherein the guide plates and guide grooves are adapted to each other.

[0013] Furthermore, the opening of the storage layer is provided with a telescopic platform, and the top of the telescopic platform is provided with a limiting block.

[0014] Furthermore, the top surface of the telescopic platform is provided with a docking groove, and the bottom of the limiting block is provided with a docking block that matches the docking groove.

[0015] Furthermore, the bottom of the cover plate is provided with a groove, and the groove extends along the length of the cover plate, and the interior of the storage layer is provided with protrusions corresponding to the groove.

[0016] Furthermore, the springs are distributed in parallel on both sides of the protrusion.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] By using a cover and spring, when no expansion card is inserted into the slot, the spring is naturally extended, allowing the cover to block the slot opening and achieve a sealing effect, helping to prevent the intrusion of external dust. When an expansion card needs to be installed, the front end of the expansion card will contact the cover and push the cover towards the storage layer. At this time, the spring is compressed, causing the cover to be retracted into the storage layer, no longer blocking the slot opening, thus allowing the expansion card to be smoothly inserted into the slot. This helps to reduce dust accumulation in the bus interface and improves the sealing of the unused interface. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] In existing technologies, bus interfaces are often directly exposed to the outside environment. When no expansion cards are installed inside, dust can easily infiltrate and accumulate inside the interface. Over time, this dust buildup can become severe, potentially leading to poor contact between the bus interface and the expansion card when an expansion card needs to be installed. This can not only interfere with smooth signal transmission but also threaten the stable operation of the device and even cause hardware failure.

[0029] Therefore, in order to solve the problem of dust accumulation in existing bus interfaces and improve the sealing of idle interfaces, this utility model discloses an expandable multi-functional bus interface component, see reference. Figures 1-5 The system includes a slot 1, the top of which has an opening for inserting a bus connector. Specifically, it also includes a cover plate 4, which is disposed inside the opening of the slot 1 to cover the opening of the slot 1; a positioning block 2, which is disposed at one end along the length of the slot 1; a storage layer 5, which is opened on the side of the positioning block 2 facing the slot 1 to store the cover plate 4; and a spring 6, which is connected between the storage layer 11 and the cover plate 4 and is used to extend and retract the cover plate 4 within the storage layer 11.

[0030] In this embodiment, when no expansion card is inserted into the slot 1, the spring 7 will naturally extend, allowing the cover 4 to fill and block the opening of the slot 1, thereby achieving a sealing effect and helping to prevent the intrusion of external dust. When an expansion card needs to be installed, the front end of the expansion card will contact the cover 4 and push the cover 4 towards the storage layer 11. At this time, the spring 7 is compressed, causing the cover 4 to be retracted into the storage layer 11, no longer blocking the opening of the slot 1, thus allowing the expansion card to be smoothly inserted into the slot 1. This helps to reduce the accumulation of dust in the bus interface and improves the sealing of the idle interface.

[0031] Furthermore, when the expansion card needs to be removed, the spring 7 enables the cover 4 to automatically reset after the expansion card is removed, re-covering the opening of the slot 1 and maintaining the sealing of the interface, so that the opening of the slot 1 can automatically close when not in use.

[0032] Example 2

[0033] Based on Embodiment 1, in order to allow the expansion card to be smoothly inserted into slot 1, refer to... Figure 3 and Figure 5 The present invention also includes a paddle 5 for moving the cover plate 4. Specifically, the cover plate 4 is provided with a paddle 5 at the end away from the spring 7, wherein the paddle 5 is vertically arranged at the top of the cover plate 4.

[0034] With the above structure, when inserting the expansion card into slot 1, the user can place the connector of the expansion card against the outside of the lever 5 and gently push it towards the positioning block 2. As the expansion card is pushed in, the lever 5 is subjected to pressure, which will cause the cover 4 to move inside the opening of slot 1 and eventually be pressed into the storage layer 11, thereby gradually opening the entrance of slot 1 that was originally blocked by the cover 4, so that the expansion card can be smoothly inserted into slot 1;

[0035] Secondly, when the expansion card is inserted into the slot 1, due to the setting of the spring 7, the paddle 5 can continuously abut against the side of the expansion card connector, so that the paddle 5 can cooperate with the inner wall of the slot 1 to clamp the expansion card connector inside the slot 1, thereby improving the stability of the expansion card.

[0036] In this embodiment, to further improve the clamping effect on the expansion card, the surface of the lever 5 is provided with a clamping groove 10, which is used to clamp the side of the bus connector. With this setting, when the user contacts the expansion card connector with the lever 5 to install the expansion card, the side of the connector can be first inserted into the clamping groove 10 to prevent the connector from slipping on the lever 5 when the cover plate 4 is pushed. Then, when the expansion card connector is fully inserted into the slot 1, the clamping groove 10 can continuously clamp the side of the connector to improve the locking effect on the expansion card and prevent the expansion card from becoming loose.

[0037] Example 3

[0038] Based on Example 2, to ensure the stability of the baffle 4 during contraction, refer to... Figures 2-3 The present invention also includes guide plates 9 and guide grooves 15. Specifically, guide plates 9 are provided on both sides of the shield 4, and guide grooves 15 are provided on the inner walls on both sides of the slot 1, wherein the guide plates 9 are sandwiched in the guide grooves 15.

[0039] In this embodiment, when the baffle 4 moves along its length in the slot 1, the guide plate 9 slides along the inside of the guide groove 15. Since the guide groove 15 encloses the guide plate 9, it helps to improve the stability of the baffle 4 during the movement, thereby reducing the probability of it shifting or shaking, and improving the stability and reliability of the overall structure.

[0040] Furthermore, to improve the stability of the cover plate 4 during reset, a groove 12 is provided at the bottom of the cover plate 4, and the groove 12 extends along the length of the cover plate 4. The inside of the storage layer 11 is provided with a protrusion 13 corresponding to the groove 12. With this arrangement, after the cover plate 4 enters the storage layer 11, the protrusion 13 can be engaged in the groove 12 to prevent the cover plate 4 from shifting position within the storage layer 11. When the cover plate 4 needs to be reset, the spring 7 naturally extends and pushes the cover plate 4 towards the slot 1. At this time, due to the setting of the protrusion 13, the movement of the cover plate 4 can be guided to prevent the cover plate 4 from shifting its path during the reset process.

[0041] In this embodiment, in order to prevent the spring 7 from bending to the side when it extends or retracts, the spring 7 is distributed parallel to both sides of the protrusion 13. With this arrangement, the spring 7 can be sandwiched between the protrusion 13 and the inner wall of the storage layer 11, thereby limiting the bending of the spring 7.

[0042] Example 4

[0043] Based on either Embodiment 1 or 3, in order to allow the expansion card to be easily removed from slot 1, refer to... Figure 2 and Figure 4 The present invention also includes a telescopic platform 7 at the opening of the storage layer 11, and a limiting block 3 at the top of the telescopic platform 7.

[0044] In this embodiment, in the initial state, the expansion card is inserted into the slot 1. The paddle 5 is pressed against the limiting block 3 due to the expansion card. When the expansion card needs to be removed, the user can remove the limiting block 3 from the positioning block 2. At this time, the paddle 5 will lose its support. Therefore, the user only needs to move the paddle 5 towards the storage layer 11 so that the cover 4 continues to move a distance towards the storage layer 11, thereby releasing the clamp on the expansion card connector and facilitating the removal of the expansion card.

[0045] In addition, to facilitate the installation and removal of the limiting block 3 from the positioning block 2, the top surface of the telescopic platform 7 is provided with a docking groove 8, and the bottom of the limiting block 3 is provided with a docking block 14 that matches the docking groove 8. Both the docking groove 8 and the docking block 14 are strip-shaped, and the surface of the docking block 14 is provided with a rubber pad to improve the tightness of the connection. When the limiting block 3 needs to be removed, the user only needs to pull the limiting block 3 upward. When the limiting block 3 needs to be reinstalled, the user only needs to align the docking block 14 with the docking groove 8 and then press the limiting block 3. Thus, the installation of the limiting block 3 can be completed without the use of tools.

[0046] Furthermore, the limiting block 3 has a flat bridge structure, so that when the limiting block 3 is installed on the telescopic platform 7, there will be a gap between the top of the limiting block 3 and the top of the telescopic platform 7, so that the cover plate 4 can extend and retract within this gap.

[0047] In summary, based on Embodiments 1 to 4, the working principle of this extended multi-functional bus interface component is as follows:

[0048] In the initial state, the spring 7 extends naturally, pushing the cover 4 towards the slot 1, so that it is located at the opening of the slot 1, effectively blocking the opening of the slot 1, preventing dust and other impurities from entering, and keeping the interface clean and sealed.

[0049] When an expansion card needs to be installed, the user can move the cover plate 4 by pushing the lever 5. Since the lever 5 is connected to the cover plate 4, and the groove 10 on its surface increases the friction with the expansion card connector, the user only needs to gently press the expansion card connector against the lever 5 and push it in the direction of the positioning block 2 to move the cover plate 4 into the storage layer 11. During this process, the guide plate 9 guides the cover plate 4 along the guide groove 15, ensuring the smooth movement of the cover plate 4 and reducing the probability of deviation or shaking.

[0050] As the cover 4 gradually retracts, the opening of slot 1 gradually opens until it is fully exposed. The user can then easily insert the expansion card into slot 1. Due to the engagement of the lever 5 with the inner wall of slot 1 and the clamping effect of the clip 10 on the expansion card connector, the expansion card is stably fixed in slot 1, helping to prevent it from loosening due to vibration or external force.

[0051] After the expansion card is used up, if it needs to be removed, the user only needs to remove the limiting block 3 on the top of the telescopic platform 7. With the limiting block 3 removed, the lever 5 loses its support, and the user can move the lever 5 towards the storage layer 11 to further compress the cover plate 4, so that it completely releases its clamping on the expansion card connector. Then the user can easily pull the expansion card out of the slot 1.

[0052] Once the expansion card is fully removed, the cover 4 automatically returns to the opening of slot 1 under the elastic force of spring 7, re-covering the entrance of slot 1 and restoring the interface to a sealed state. This process requires no manual intervention, achieving automatic closure and sealing of the interface, thus improving overall ease of use and sealing performance.

[0053] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0054] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
