Technical Field
[0001] This utility model relates to the field of circuit board technology, and in particular to circuit board interface connection structure. Background Technology
[0002] In today's era of rapid development of electronic devices, circuit boards, as the core component of electronic devices, play a vital role. They connect various electronic components in an orderly manner to realize signal transmission and circuit functions. Their performance directly affects the overall performance of electronic devices. The interface connection structure, as the bridge for communication between circuit boards and between circuit boards and external devices, determines whether the circuit board can operate stably and efficiently. As electronic devices move towards miniaturization, integration, and high performance, extremely stringent requirements are placed on the interface connection structure of circuit boards in terms of space occupation, connection reliability, and signal transmission quality. Ordinary circuit board interface connection structures are no longer able to meet these complex and ever-changing needs.
[0003] In practical use, the stability of circuit board interface connections is poor. Affected by vibration and external forces from plugging and unplugging, the interfaces are prone to loosening, resulting in poor contact, which in turn leads to signal interruption and data transmission errors, seriously interfering with the normal operation of the equipment. The structural connection is also not compact enough, occupying too much space in the limited space inside electronic equipment, which is not conducive to the miniaturization and integration of the equipment. To solve these problems, existing equipment uses the addition of fixing clips and screws to improve the connection stability, and uses specially shaped interfaces and adapter plates to optimize the space layout, making the structure more stable and compact. However, the above connection structure does not take into account that the interfaces are prone to damage after long-term use, and the convenience of replacement is insufficient.

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.
[0031] Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 An embodiment of this utility model provides a circuit board interface connection structure, including a board body 1. Multiple sliding grooves 4 are provided at the top left edge of the board body 1. A limiting groove 3 is provided at the bottom of the sliding groove 4. A sliding column 5 is slidably connected to the inner wall of the sliding groove 4. A limiting block 6 is fixedly connected to the bottom of the outer wall of the sliding column 5. A sliding piece 7 is slidably connected to the lower middle part of the outer wall of the sliding column 5. An interface component 8 is fixedly connected to the outer wall of the sliding piece 7. A pressure plate 9 is fixedly connected to the top of the interface component 8. A locking plate 10 is rotatably connected to the top of the sliding column 5. A locking screw 11 is threadedly connected to the middle of the top of the locking plate 10. A sealing mechanism 2 is provided on the left side of the board body 1. The sealing mechanism 2 is used to close the interface.
[0032] Specifically, multiple sliding grooves 4 are formed on the plate 1. These sliding grooves 4 not only have precise dimensions to ensure the stability of the sliding connection, but also ensure the precise positioning of the sliding components through the limiting grooves 3. Limiting blocks 6 are fixedly connected to the bottom of the outer wall of the sliding column 5. These limiting blocks 6 ensure that the movement of the sliding column 5 in the sliding groove 4 will not exceed the predetermined range. An interface piece 8 is fixedly connected to the outer wall of the sliding piece 7. The interface piece 8 has a pressure plate 9, which enables the pressure plate 9 to effectively respond to the pressure brought by the screw. The locking plate 10 cooperates with the locking screw 11, which provides a reliable locking mechanism for the plate 1. The sealing mechanism 2 is specifically used to close the interface to ensure the safety and sealing of the entire structure.
[0033] Please see the appendix Figure 1 Appendix Figure 2 and attached Figure 4 The sealing mechanism 2 includes a fixing block 201. The bottom of the fixing block 201 is fixedly connected to the front and rear parts of the top left side of the plate 1. A rotating shaft 202 is rotatably connected to the inner wall of the fixing block 201. A cover plate 203 is fixedly connected to the outer wall of the rotating shaft 202. A pull tab 204 is fixedly connected to the bottom left side of the cover plate 203. A rubber sheet 205 is fixedly connected to the top of the cover plate 203. Multiple rubber strips 206 are fixedly connected to the front and rear parts of the left side of the rubber sheet 205. Multiple structural grooves 207 are opened on the front and rear sides of the top of the interface component 8.
[0034] Specifically, the fixing block 201 is fixed together with the plate 1. In order to realize the rotation function, a rotating shaft 202 is rotatably connected to the inner wall of the fixing block 201. The rotating shaft 202 allows the cover plate 203 to rotate flexibly. A pull tab 204 is fixedly connected to the bottom left side of the cover plate 203 through a stable connection, so that the operator can easily control the opening and closing of the cover plate 203. The cover plate 203 is sealed by a rubber sheet 205. This rubber sheet 205 not only provides a sealing effect, but also provides a certain buffering effect when the cover plate 203 is closed. In order to enhance the sealing effect, multiple rubber strips 206 are fixedly connected to the front and rear parts of the left side of the rubber sheet 205. These rubber strips 206 can fit tightly with the structural groove 207, thereby achieving a better sealing effect.
[0035] Please see the appendix Figure 1 The top of the board 1 is provided with multiple component holes 12. A nameplate 13 is fixedly connected to the front left side of the top of the board 1. Multiple mounting holes 14 are provided on the front and back right sides of the top of the board 1. The mounting holes 14 are arranged symmetrically. A heat sink 15 is fixedly connected to the middle left side of the top of the board 1. Multiple heat sinks 16 are fixedly connected to the front and back sides of the heat sink 15.
[0036] Specifically, these component holes 12 facilitate the installation of electronic components, the nameplate 13 not only identifies product information but also enhances the product's professional feel, the layout of these mounting holes 14 presents a symmetrical aesthetic, making the installation process more convenient and precise, the presence of the heat sink 15 is crucial for the heat dissipation of electronic devices, these heat sinks 16 effectively dissipate heat from electronic devices by increasing the heat dissipation area, ensuring the stable operation of the equipment.
[0037] Please see the appendix Figure 1 Multiple ordinary resistors 17 are fixedly connected to the top left of the board body 1. Multiple varistors 18 are fixedly connected to the front and rear sides of the top middle of the board body 1. A transformer 19 is fixedly connected to the top middle of the board body 1. An inductor 20 is fixedly connected to the front right side of the top of the board body 1. A capacitor 1 21 is fixedly connected to the rear right side of the top of the board body 1. A capacitor 22 is fixedly connected to the right middle of the top right side of the board body 1.
[0038] Specifically, the ordinary resistor 17 limits the flow of current in the circuit, protecting the circuit from overcurrent damage. The varistor 18 changes its resistance value when the voltage exceeds a certain threshold, thereby protecting other components in the circuit. The transformer 19 converts the voltage level of alternating current, playing a crucial role in power supply and signal transmission. The inductor 20 stores energy in the circuit and suppresses current changes, which is very helpful for stabilizing circuit operation. Capacitor 21 stores charge and acts as a filter in the circuit, helping to reduce voltage fluctuations. Capacitor 22 is also used for filtering. Together with capacitor 21, they ensure a more stable voltage in the circuit, providing a smoother power supply for electronic devices.
[0039] Working principle: The sliding column 5 can slide through the sliding groove 4 through the limiting groove 3 opened on the plate 1, and the limiting block 6 is locked into the limiting groove 3. Since the outer wall of the sliding column 5 is slidably connected to the interface component 8 through the sliding piece 7 and the pressure plate 9, when the interface component 8 is installed, it is only necessary to slide the sliding column 5 into the sliding groove 4, rotate the sliding column 5 to align the limiting block 6 with the limiting groove 3, tighten the locking screw 11 threaded on the locking plate 10, so that the bottom end of the locking screw 11 presses against the pressure plate 9, thereby lifting the sliding column 5 rotatably connected to the bottom of the locking plate 10, so that the limiting block 6 is locked into the limiting groove 3, and the locking is completed. This structure avoids the contact between the circuit board and the screw, which has a protective effect. Moreover, the structure can be disassembled and assembled with a single screw, which improves the convenience of disassembly and assembly and meets the connection requirements.
[0040] By setting the fixing block 201, the cover plate 203 fixed to the outer wall of the rotating shaft 202 can be rotatably connected to the structure. When the interface is not in use, push the cover plate 203 to squeeze the rubber sheet 205 on its top into the inner wall of the interface. Since the interface part 8 has a structural groove 207, after being squeezed in place, the rubber strip 206 on the left side of the rubber sheet 205 will be stuck into the groove to seal it, preventing external dust and water stains from entering and damaging the structure. When using the interface, simply pull the pull tab 204, and the elasticity of the rubber sheet 205 can easily open the structure. This structure can prevent foreign objects from entering the interface and circuit board, improve the service life of the structure, and meet the sealing requirements.
[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
