[0002] With the development of electronic equipment integration and miniaturization, the performance requirements of board-to-board connectors are constantly increasing. Under complex working conditions, the stability of connectors becomes crucial. Traditional board-to-board connectors mostly rely on plug-in connections or simple snap-fit fixation. When subjected to vibration and impact, they are prone to loosening and falling off, affecting the stability and reliability of signal transmission, and even causing electronic equipment failure.
[0003] In addition, the snap-fit structure of some connectors is inconvenient to operate, and the assembly and disassembly process is time-consuming and labor-intensive, which reduces production efficiency. At the same time, after repeated insertion and removal, the wear of the snap-fit will reduce its anti-disengagement performance, which cannot meet the requirements of long-term stable operation of electronic devices. To address this, we propose a board-to-board connector with an anti-disengagement snap-fit. Utility Model Content

[0036] Structural Description:
[0037] Connector connection support base plate 1: As the basic support component of the entire connector, it provides an installation platform for other components. The top surface is provided with a top guide groove 13, a connection slot 14, a limiting slide groove 12, and a connection support platform 7. The guide groove and slot are used to guide the insertion components to work, the limiting slide groove is used to install the side limiting and fixing components, and the connection support platform provides an installation position for the anti-disengagement buckle components, ensuring that each component is installed in an orderly manner and enhancing the overall structural stability.
[0038] Board-to-board connector 4: It is the core component for connecting circuit boards. It is connected to the connector connection support base plate 1 through the guide insertion assembly. Under the action of the guide insertion assembly, it is accurately inserted into the corresponding position to achieve electrical connection. At the same time, it works with the side limiting and fixing assembly and the anti-disengagement buckle assembly to maintain stability during equipment operation and ensure stable signal transmission.
[0039] Top guide groove 13: It is formed on the top surface of the connector connection support base plate 1. It is usually a long strip groove structure. Its width and depth are precisely designed according to the outer dimensions of the board-to-board connector 4 to ensure that the board-to-board connector 4 can slide smoothly in the groove. The inner wall of the guide groove is smoothed to reduce friction and facilitate the insertion of the connector. It also plays a role in initial positioning and guidance.
[0040] Connection slots 14: Equally distributed on the bottom surface inside the top guide groove 13, their shape and size match the pins or connection parts of the board-to-board connector 4. The slots are made with high-precision processing technology to ensure a tight fit with the connector pins, achieve precise guidance, reduce installation deviation, and ensure the accuracy of electrical connection.
[0041] Elastic sealing plate 2: Generally made of elastic materials such as rubber or silicone, it has good flexibility and sealing performance. It is fixed on the inner side of the top of the limiting slide groove 12. Its shape is adapted to the top of the limiting slide groove 12. It can effectively prevent dust, debris and other objects from entering the limiting slide groove 12 and avoid affecting the performance of the components. At the same time, when the equipment is subjected to vibration and impact during operation, the elastic sealing plate 2 can play a buffering role and reduce the impact on other components.
[0042] Sliding limit block 3: It is usually a block structure, made of wear-resistant and high-strength materials, such as engineering plastics or metals, and connected to the limit spring 11. Under the elastic force of the limit spring 11, it tightly abuts against the side of the board-to-board connector 4, restricting its displacement in the horizontal direction and ensuring that the connector always maintains a stable connection state. The sliding limit block 3 and the limit slide groove 12 adopt a sliding fit. Its surface is smoothed to reduce frictional resistance and ensure smooth sliding.
[0043] Limiting spring 11: Installed inside the limiting slide groove 12, one end is fixed to the bottom of the limiting slide groove 12, and the other end is connected to the sliding limiting block 3. It is made of spring material with a suitable elastic coefficient. After installation, it is in a compressed state and can continuously provide outward pushing force to the sliding limiting block 3, so that it always maintains the pressing force on the side of the board-to-board connector 4, ensuring the limiting and fixing effect.
[0044] Buffer support plate 5: Located on the bottom surface of the anti-detachment rotating buckle 6, it is connected to the board-to-board connector 4. It is usually made of materials with certain elasticity and buffering properties, such as rubber or silicone, which can absorb part of the impact force when the equipment is subjected to vibration or impact, and prevent the board-to-board connector 4 from being damaged by excessive external force, thus protecting the connector.
[0045] Anti-detachment rotating buckle 6: It is rotatably connected to the connecting support platform 7 on the top surface of the connector connecting support base plate 1 through the rotating connecting hole 15. The side of the buckle is provided with a connecting sliding hole 10 for cooperating with the limiting sliding rod 9. The anti-detachment rotating buckle 6 is generally made of high-strength engineering plastic or metal, with sufficient strength and rigidity, and can withstand a large external force when fixing the board-to-board connector 4 to ensure the stability of the connection.
[0046] Magnetic fixing block 8: Fixed to one end of the limiting sliding rod 9, made of magnetic material, such as neodymium iron boron magnet, attracts the corresponding magnetic part on the connector connection support base plate 1, enhances the fixing effect of the limiting sliding rod 9, prevents it from accidentally coming off, and further improves the reliability of the anti-loosening buckle assembly.
[0047] Limiting sliding rod 9: One end is connected to the magnetic fixing block 8, and the other end is inserted into the connecting sliding hole 10 on the side of the anti-detachment rotating buckle 6. It is made of high-strength and wear-resistant materials, such as metal. Its diameter is adapted to the connecting sliding hole 10 to ensure smooth sliding and tight fit. The limiting sliding rod 9 plays a connecting and positioning role in the anti-detachment buckle assembly, connecting the anti-detachment rotating buckle 6 to the magnetic fixing block 8 to achieve anti-detachment fixation of the board-to-board connector 4.
[0048] Connecting sliding hole 10: It is opened on the side of the anti-detachment rotating buckle 6. Its length and diameter are designed according to the size of the limiting sliding rod 9 to ensure that the limiting sliding rod 9 can slide smoothly in the hole, while having a certain fitting accuracy to ensure that the connection between the anti-detachment rotating buckle 6 and the limiting sliding rod 9 is firm and reliable.
[0049] Working principle: When using this utility model, when installing the board-to-board connector 4, first align it with the top guide groove 13 on the top surface of the connector connection support base plate 1. The top guide groove 13 plays a preliminary positioning and guiding role, allowing the board-to-board connector 4 to quickly find the approximate insertion direction. Then, the board-to-board connector 4 slides down along the guide groove. At this time, the connecting slots 14 play a precise guiding function. The connecting slots 14 are evenly distributed on the bottom surface inside the top guide groove 13 and slide with the board-to-board connector 4, ensuring that the pins or connecting parts of the connector can be accurately inserted into the corresponding positions, effectively reducing installation deviation, improving connection accuracy, and ensuring the accuracy of electrical connection. After the board-to-board connector 4 is inserted into place, the side limiting and fixing assembly begins to work. The limiting groove 12 is formed on the top surface of the connector connection support base plate 1. One end of the internal limiting spring 11 is fixed to the inner side of the limiting groove 12, and the other end is connected to the sliding limiting block 3. When the limiting spring 11 is in a compressed state, it will exert an outward pushing force on the sliding limiting block 3, so that the sliding limiting block 3 tightly abuts against the side of the board-to-board connector 4. The elastic sealing plate 2 fixed to the inner side of the top of the limiting groove 12 can prevent dust, debris, etc. from entering the limiting groove 12 and avoid affecting the performance of the assembly. On the other hand, when the equipment is subjected to vibration and impact during operation, the elastic sealing plate 2 can act as a buffer. The function of the anti-detachment buckle assembly, together with the sliding limit block 3, is to limit the horizontal displacement of the board-to-board connector 4, ensuring that the connector always maintains a stable connection. The anti-detachment buckle assembly is a key part to ensure a stable connection of the connector. The connector connection support base 7 on the top surface of the connector connection support base plate 1 has a rotating connection hole 15. The anti-detachment rotating buckle 6 is rotatably connected to it through the rotating connection hole 15. During installation, the anti-detachment rotating buckle 6 is rotated around the rotating connection hole 15 to a suitable position, so that the connecting sliding hole 10 on the side of the anti-detachment rotating buckle 6 is aligned with the limiting sliding rod 9. Then, the limiting sliding rod 9 is inserted. The magnetic fixing block 8 fixed at the other end of the limiting sliding rod 9 will connect with the connector connection support. The corresponding magnetic parts on the support plate 1 attract each other, further enhancing the fixing effect of the limiting sliding rod 9 and preventing it from accidentally coming off. The buffer support plate 5, which is fixedly connected to the bottom surface of the anti-disengagement rotating buckle 6, is connected to the board-to-board connector 4. When the equipment is subjected to vibration or impact, the buffer support plate 5 can absorb part of the impact force, preventing the board-to-board connector 4 from being damaged by excessive external force. Through the synergistic effect of the anti-disengagement rotating buckle 6, the limiting sliding rod 9, and the magnetic fixing block 8, the board-to-board connector 4 is firmly fixed on the connector connection support plate 1, effectively preventing loosening and falling off, ensuring stable signal transmission, and reducing the probability of electronic equipment failure due to loose connectors.
