Description

Technical Field

[0001] This utility model relates to the field of self-protection technology for OPENVPX interface conversion boards, and more specifically, to self-protection OPENVPX interface conversion boards. Background Technology

[0002] The OPENVPX interface conversion board is a key signal conversion component developed based on the VPX architecture (military standard modular interconnect architecture). Its core function is to realize protocol conversion and data interaction between the OPENVPX standard interface and other types of interfaces (such as PCIe, Ethernet, RS485, etc.). It is widely used in fields with extremely high requirements for data transmission reliability and compatibility, such as industrial control, aerospace, communication equipment, and radar systems. This board needs to ensure high-speed data interoperability between multiple devices under complex operating conditions. It must meet the modularity and high bandwidth characteristics of the OPENVPX architecture while adapting to the interface requirements of different peripherals. It is the core unit for building stable and flexible modular electronic systems and directly determines the data transmission efficiency and operational stability of the entire system.

[0003] However, traditional OPENVPX interface conversion boards have significant deficiencies in transportation protection, installation stability, and connector protection, severely impacting their reliability and lifespan. Firstly, the boards are susceptible to damage during transport due to rough handling by express delivery companies: traditional boards rely solely on simple cardboard boxes or foam packaging, lacking specific anti-bending structural designs. Under the impact and pressure of sorting and transfer, the boards are prone to bending and solder joint detachment, leading to hardware damage. Furthermore, installation often employs a method of "3-4 bolts directly fixing to the equipment casing," with the fixing points concentrated on one side of the board. Over long-term use, equipment vibrations are transmitted to the board through these bolts, causing loosening of the connection between the board and the interface, and even altering line impedance. This severely affects data transmission stability, increases system error rates, and makes the boards prone to tilting during installation. On the other hand, traditional circuit boards have rudimentary protection measures for precision connectors (such as OPENVPX external interfaces), consisting of only a single plastic shell without a fixed structure. During transportation, the shell is easily detached due to bumps and collisions, exposing the connector to dust and scratches, affecting the interface contact performance, or even causing damage to the connector, increasing equipment maintenance costs and failure risks.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a self-protected OPENVPX interface conversion board, which has the following beneficial effects: 1. This self-protective OPENVX interface conversion card, through the arrangement of a card holder, a limiting bracket, a telescopic bracket, and a fixing plate, enables the card to improve its anti-bending performance and installation stability. The card holder, limiting bracket, limiting groove, telescopic bracket, limiting slider, first knob, second knob, and fixing plate work together to form a rigid protective frame on the outside of the card during use, enhancing its anti-bending performance.

[0018] Please see Figures 1-4 The self-protecting OpenVPX provided in this embodiment The interface conversion board has a first slot 2 on the inner wall of its card holder 1. The card holder 1 is snapped onto the upper surface of the conversion board body 20 through the first slot 2. A rubber pad is provided on the inner wall of the first slot 2. Two symmetrically arranged limit frames 3 are rotatably connected to both ends of the card holder 1. Limit slots 4 are provided on the outer surface of the limit frames 3. A telescopic frame 5 is inserted into the inner wall of the limit frames 3. A limit slider 6 is fixedly connected to the outer surface of the telescopic frame 5. The outer surface of the limit slider 6 is slidably connected to the inner wall of the limit slot 4. A first knob 7 is threadedly connected to the middle of the limit slider 6. The outer surface of the first knob 7 abuts against the outer surface of the limit frame 3. A second slot 8 is provided on the inner wall of the telescopic frame 5. A rubber pad is provided on the inner wall of the second slot 8. A rotating block 9 is threadedly connected to the lower inner wall of the telescopic frame 5 through a second knob 10. A fixing plate 11 is fixedly connected to the outer surface of the rotating block 9. A through groove 12 is provided on the outer surface of the fixing plate 11. This constitutes the core structure for the board's anti-bending protection and installation fixation.

[0019] Specifically, the snap-fit ​​bracket 1 clamps the upper surface of the conversion plate body 20 through the first snap-fit ​​groove 2, and the rubber pad cushions to prevent wear on the plate surface; the two limiting brackets 3 are rotated to both sides of the conversion plate body 20, pushing the telescopic bracket 5 to slide along the inner wall of the limiting bracket 3, so that the limiting slider 6 slides synchronously along the limiting groove 4 until the second snap-fit ​​groove 8 of the telescopic bracket 5 engages with the two sides of the conversion plate body 20, and the rubber pad further enhances the fit stability; rotating the rotating block 9 causes the fixing plate 11 to flip, so that the outer surface of the fixing plate 11 abuts against the lower surface of the conversion plate body 20, and the first knob 7 is tightened (the first knob 7 abuts against the outer surface of the limiting bracket 3) to fix the limiting slider. Position 6, tighten the second knob 10 to fix the rotating block 9. At this time, the snap-fit ​​bracket 1, the limiting bracket 3, the telescopic bracket 5 and the fixing plate 11 form a closed rigid protective frame on the outside of the conversion plate body 20, which effectively resists the impact and squeezing during transportation and prevents the plate from bending and the weld points from falling off. During installation, loosen the first knob 7 and the second knob 10 to flexibly adjust the rotation angle of the limiting bracket 3 and the extension length of the telescopic bracket 5, so that the through groove 12 of the fixing plate 11 can be adapted to any bolt hole in the equipment. After fixing with bolts through the through groove 12, tighten the knob to disperse the fixing points to avoid the plate from tilting, greatly improve the installation stability and reduce the loosening of the connection caused by equipment vibration.

[0020] Please see Figures 1-5 The self-protected OpenVPX interface conversion board has a card holder 1 with a limiting block 13 fixedly connected to the front. The external connector of the conversion board body 20 is fitted with a connector protective cover 14. A limiting rod 15 is fixedly connected to the upper surface of the connector protective cover 14. A pinch piece 16 is fixedly connected to the upper end of the limiting rod 15. A limiting plug 17 is fixedly connected to one side of the upper end of the limiting rod 15. A barb 18 is fixedly connected to the outer surface of the limiting plug 17. An easy-tear groove 19 is provided at the connection between the limiting plug 17 and the limiting rod 15, which constitutes the key structure for the protection and anti-tampering of the board connector.

[0021] Specifically, the connector protective cover 14 is tightly fitted onto the external connector of the conversion board body 20. The limiting rod 15 is pushed so that the limiting rod 17 is inserted into the inner side of the limiting block 13. The barbs 18 on the outer surface of the limiting rod 17 engage with the inner wall of the limiting block 13, preventing the connector protective cover 14 from accidentally falling off due to bumps or collisions. This effectively isolates dust and impurities, avoids scratch damage to the connector, and ensures interface contact performance. When the board needs to be installed and used, the operator pinches the gripper 16 with their fingers and tears it outward. The easy-tear groove 19 at the connection between the limiting rod 17 and the limiting rod 15 will break under force. The breakage mark can visually prove that the conversion board body 20 has been used, forming a "one-time use and damage" anti-tamper mark, preventing unauthorized personnel from opening the protection or tampering with the board, and improving the safety of equipment use.

[0022] In summary, during the overall use of the equipment: During transportation, the clip 1 is secured to the upper end of the conversion plate body 20 via the first clip 2. The two first clips 2 are bent so that the two telescopic clips 5 are secured to both sides of the conversion plate body 20 via the inner second clip 8. Then, the fixing plate 11 and the rotating block 9 are rotated so that the outer surface of the fixing plate 11 abuts against the lower surface of the conversion plate body 20. Afterwards, the first knob 7 and the second knob 10 are tightened. When the first knob 7 is tightened, one side of the first knob 7 abuts against the outer surface of the limiting bracket 3, thereby fixing the limiting slider 6 inside the limiting groove 4. Tightening the second knob 10 prevents the rotating block 9 from rotating, thus completely encasing the conversion plate body 20 and preventing bending during transportation. When installing it inside the equipment, the first knob 7 and the second knob 10 are loosened. With two knobs 10, the spacing and angle of the limiting frame 3, telescopic frame 5, and fixing plate 11 can be freely adjusted, allowing them to be installed at any bolt hole inside the equipment. After the bolt passes through the through slot 12, it is screwed into the designated position, and then the two second knobs 10 and the first knob 7 are tightened, which improves the stability of the installation. During transportation, the connector protective cover 14 is fitted onto the connector of the conversion board body 20, and the limiting rod 17 and barbs 18 are locked inside the limiting block 13 to prevent the connector protective cover 14 from falling off. When installing and using, the fingers pinch the grip piece 16 and tear it outward. At this time, the connection between the limiting rod 17 and the limiting rod 15 will break at the easy-tear groove 19. The breakage proves that the conversion board body 20 has been used, thus improving the safety protection performance of the conversion board body 20.

[0023] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
