Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0034] Please see Figures 1 to 2 As shown, this utility model provides a PCB board connection structure, including:
[0035] Motherboard 1 has multiple through holes;
[0036] Sub-board 2 is arranged parallel to the main board 1. The sub-board 2 is provided with a plurality of connection holes, and the through holes correspond one-to-one with the connection holes.
[0037] Multiple connecting components 4 are provided, with each through hole connected to a corresponding connecting hole via a connecting component 4. Each connecting component includes a connecting rod 401, a retaining ring 402, and a limiting block 403. The two ends of the connecting rod 401 extend from the through hole and the connecting hole, respectively. The retaining ring 402 is provided at one extended end of the connecting rod 401 for limiting, and the limiting block 403 is provided at the other extended end of the connecting rod 401 for limiting. The end of the connecting rod 401 with the retaining ring is also provided with a thread. This threaded end is used to connect with other adjacent devices. After the connection is completed, the connecting rod 401 is fixed by the connecting hole of the device.
[0038] A support sleeve 5 is sleeved on the connecting rod 401. The support sleeve 5 is located between the main plate 1 and the sub-plate 2, and the two end faces of the support sleeve 5 are in contact with the main plate 1 and the sub-plate 2, respectively.
[0039] It should also be noted that, in use, the main board 1 and the sub-board 2 are set first, and the connecting rod 401 is passed through the corresponding through hole and connecting hole. One end of the connecting rod 401 is limited by the limiting block 403, and the other end of the connecting rod 401 is connected to the adjacent device and limited by the snap ring 402 and the connecting device.
[0040] In one embodiment, the diameters of the through hole and the connecting hole are the same as the diameter of the connecting rod 401, so that the connecting rod 401 will not wobble when installed in the through hole and the connecting hole.
[0041] For example, the limiting block 403 is a prism, and the axis of the limiting block 403 coincides with the connecting rod 401.
[0042] It should also be noted that, in order to make it easier to operate the connecting rod 401, the limiting block 403 is designed as a prism, such as a hexagonal prism. Tools can be used to operate the connecting rod 401, making it easier and less strenuous to remove the connecting rod 401.
[0043] For example, the limiting block 403 is integrally formed with the connecting rod 401.
[0044] It should also be noted that, in order to simplify the structure, the limiting block 403 and the connecting rod 401 can be integrally formed as a hexagonal screw, which can be directly inserted from the through hole during installation and then protruded from the connecting hole. The protruding end from the connecting hole is used for threaded connection with adjacent equipment.
[0045] For example, the outer wall of the end of the connecting rod 401 with the retaining spring is threaded.
[0046] It should also be noted that the purpose of setting the threads is, on the one hand, to play a certain behavioral role in the snap ring 402 through the threads, so as to prevent the snap ring 402 from falling off when installing adjacent equipment.
[0047] For example, all of the connection components 4 are arranged around the edges of the motherboard 1 and the sub-board 2.
[0048] It should also be noted that placing all the connecting components 4 at the edges of the motherboard 1 and the sub-board 2 is intended to ensure the connection strength between the motherboard 1 and the sub-board 2, while providing sufficient installation positions for the pins 3 and optimizing the installation structure.
[0049] For example, a first gasket is provided between the support sleeve 5 and the main board 1, and the first gasket is sleeved on the connecting rod 401.
[0050] The first gasket is a rubber gasket. Rubber gaskets have a certain degree of elasticity and flexibility, which can play a role in buffering and shock absorption during the operation of equipment and pipelines. When equipment or pipelines are subjected to external impact or vibration, rubber gaskets can absorb some energy and reduce damage to equipment and pipelines.
[0051] It should also be noted that, in order to avoid direct contact between the support sleeve 5 and the motherboard 1, which could damage the motherboard 1, a first gasket is provided to buffer the connection between the two.
[0052] For example, a second gasket is provided between the support sleeve 5 and the sub-plate 2, and the second gasket is sleeved on the connecting rod 401.
[0053] It should also be noted that, in order to avoid direct contact between the support sleeve 5 and the sub-plate 2, which could damage the sub-plate 2, a second gasket is provided to buffer the connection between the two.
[0054] The second gasket is a rubber gasket. Rubber gaskets possess elasticity and flexibility, enabling them to buffer and absorb shocks during equipment and pipeline operation. When equipment or pipelines are subjected to external impacts or vibrations, the rubber gasket can absorb some of the energy, reducing damage to the equipment and pipelines.
[0055] For example, a pin 3 is provided between the main board 1 and the sub-board 2, and the pin 3 is connected to the main board 1 and the sub-board 2 respectively.
[0056] It should also be noted that, as a connector component, the pins ensure accurate and stable transmission of power and signals between the motherboard and the secondary board. This is the most basic and core function of the pins.
[0057] The motherboard 1 and sub-board 2 are designed with a detachable connection so that the components connected by pin 3 can be easily removed and replaced. This is highly advantageous for maintaining and repairing the circuit board, because if a component fails, only the portion connected by pin 3 needs to be replaced, without requiring extensive modifications to the entire circuit board.
[0058] Pins 3 can also be used as a means of mechanical support and fixing components. They can increase the mechanical strength between the main board 1 and the sub-board 2, and prevent the main board 1 and the sub-board 2 from moving or loosening during vibration or transportation.
[0059] For example, a retaining ring groove is also provided on the connecting rod 401. The retaining ring groove is located at the end of the connecting rod 401 that extends out of the connecting hole, and the retaining ring 402 is engaged in the retaining ring groove.
[0060] It should also be noted that, in order to further prevent the snap ring 402 from falling off and to improve the limiting effect of the snap ring 402 on the connecting rod 401, a snap-fit groove is provided to fix the snap ring 402.
[0061] In one embodiment, to improve structural strength, the connecting rod 401 is made of 304 stainless steel.
[0062] In one embodiment, a plurality of support blocks 6 are provided on the outer side of the sub-plate 2. The support blocks 6 are distributed on the edge of the sub-plate 2. The support blocks 6 provide additional support and help prevent the circuit board from deforming or being damaged due to vibration or external pressure.
[0063] In summary, the PCB board connection structure of this utility model can connect the main board 1 and the sub-board 2 through multiple connecting rods 401. Snap rings 402 and limiting blocks 403 are respectively provided at both ends of the connecting rods 401 to prevent the main board 1 and the sub-board 2 from falling off. A support sleeve 5 is provided between the main board 1 and the sub-board 2 for support, effectively ensuring the stability of the connection between the main board 1 and the sub-board 2. This solves a series of problems existing in the PCB board connection process, such as inconvenient disassembly and assembly, difficult maintenance, and excessive pressure on the pins between boards. Through the improved design of the connection structure, simple installation and disassembly are achieved, reducing production and maintenance costs, while enhancing the reliability of the connection, thereby improving the overall user experience.
[0064] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
