Description

Technical Field

[0001] The utility model relates to the technical field of PCBA boards, and particularly relates to an anti-loosening PCBA structure. Background Technique

[0002] PCBA is the whole process of PCB bare board through SMT component mounting and then through DIP plug-in, abbreviated as PCBA, also known as printed circuit board, printed wiring board, which is an important electronic component, a support for electronic components, and a provider of electrical connection for electronic components.

[0003] During the use of the existing PCBA board, it is usually directly connected to the mounting posts through bolts to install and use the PCBA board. However, in the actual use process, when affected by external forces, such as the overall external components falling, which will cause vibration, the electronic components on the surface of the PCBA board are likely to fall off from the surface of the PCBA board, resulting in the inability of the PCBA board to be used normally. Therefore, we propose an anti-loosening PCBA structure. Content of the Utility Model

[0004] In view of the above problems, the utility model provides an anti-loosening PCBA structure, which can solve the problems existing in the above background technique.

[0007] In a further technical solution, fixing mounting holes are formed at the end of the surface of the PCBA board, and auxiliary positioning sleeves are fixedly connected to the positions corresponding to the fixing mounting holes at the bottom end of the PCBA board.

[0008] In a further technical solution, the active anti-loosening mechanism includes a mounting frame, a plurality of threaded mounting holes are formed at the top end of the mounting frame, and a connection resistance mechanism is connected inside the threaded mounting holes through threads.

[0012] In a further technical solution, a guiding arc surface is provided inside the bottom end of the auxiliary positioning sleeve.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The provided movable anti-loosening mechanism can ensure that the electronic components on the top of the PCBA board are always in a stable state with the PCBA board, so as to ensure the stable use of the PCBA board. At the same time, the movable anti-loosening mechanism can automatically adapt to the height of the electronic components on the top of the PCBA board and always maintain a state of resisting the electronic components, thereby ensuring connection stability and avoiding loosening.

[0022] The following further explains the embodiments of the present invention in conjunction with the accompanying drawings.

[0023] Embodiment:

[0024] As Figures 1 - 4 shown, a loosening-proof PCBA structure includes a PCBA board 1. Fixed installation sleeve blocks 2 are symmetrically arranged at the top end of the PCBA board 1, and a movable anti-loosening mechanism 3 is movably connected inside the fixed installation sleeve blocks 2.

[0025] The working principle of the above technical solution is as follows:

[0026] During use, the movable anti-loosening mechanism 3 can resist the electronic components at the top of the PCBA board 1 downward, avoiding the mutual separation between the electronic components and the PCBA board 1 when vibrating.

[0027] In another embodiment, as Figure 1 shown, fixed installation holes 4 are opened at the end of the surface of the PCBA board 1, and an auxiliary positioning sleeve 5 is fixedly connected to the position corresponding to the fixed installation holes 4 at the bottom end of the PCBA board 1.

[0028] When connecting the PCBA board 1 and the installation column with bolts, it is convenient to quickly sleeved the auxiliary positioning sleeve 5 on the outer surface of the installation column, so that the fixed installation holes 4 and the installation column can be quickly positioned, and the operation is convenient.

[0029] In another embodiment, as Figure 2 shown, the movable anti-loosening mechanism 3 includes an installation frame 6. A plurality of threaded installation holes 7 are opened at the top end of the installation frame 6, and a connection resistance mechanism 8 is connected inside the threaded installation holes 7 by threads.

[0030] It is convenient to quickly rotate and insert the connection resistance mechanism 8 into the threaded installation holes 7, so that the connection between the connection resistance mechanism 8 and the installation frame 6 can be quickly fixed, and thus it can be quickly assembled and used.

[0031] In another embodiment, as Figure 1 and Figure 2As shown, fixed connection blocks 9 are fixedly connected to both sides of the installation frame 6. A connecting support leg 10 is fixedly connected to the bottom end of the fixed connection block 9. The connecting support leg 10 and the PCBA board 1 are connected and fixed by bolts.

[0032] When the installation frame 6 is inserted into the inner side of the movable anti-loosening mechanism 3, it is convenient to connect and fix the PCBA board 1 and the connecting support leg 10 through bolts, and then the installation frame 6 can be fixed, so that the installation frame 6 can be used stably and the operation is convenient.

[0033] In another embodiment, as Figure 3 shown, the connection resistance mechanism 8 includes an installation sleeve 11. A force-bearing spring 12 is fixedly connected to the top end inside the installation sleeve 11. A movable installation disc 13 is fixedly connected to the bottom end of the force-bearing spring 12. A connection resistance rod 14 is fixedly connected to the bottom end of the movable installation disc 13. Installation threads 15 are provided on the bottom surface of the installation sleeve 11. A hexagonal block 16 is fixedly connected to the top end of the installation sleeve 11.

[0034] It is convenient for the force-bearing spring 12 to provide a downward acting force on the movable installation disc 13, so that the bottom end of the connection resistance rod 14 always resists the electronic component downward, and then the electronic component and the PCBA board 1 can be in a stable connection state.

[0035] In another embodiment, as Figure 4 shown, fixing through grooves 17 are provided on the surface of the auxiliary positioning sleeve 5.

[0036] Through the fixing through grooves 17, it can be ensured that when the auxiliary positioning sleeve 5 is sleeved on the outer surface of the installation column, the auxiliary positioning sleeve 5 can expand itself within a certain error range, improving the practicability of the auxiliary positioning sleeve 5.

[0037] In another embodiment, as Figure 4 shown, a guiding arc surface 18 is provided on the inner side of the bottom end of the auxiliary positioning sleeve 5.

[0038] When the auxiliary positioning sleeve 5 is sleeved on the surface of the installation column, it is convenient to perform guiding through the guiding arc surface 18, so that the auxiliary positioning sleeve 5 can be smoothly sleeved on the outer surface of the installation column.

[0039] Working principle of the utility model: During use, first move the bottom end of the mounting frame 6 along the inner side of the movable anti-loosening mechanism 3. When the bottom end of the mounting frame 6 completely moves to the inner side of the movable anti-loosening mechanism 3, use bolts to connect and fix the connecting support leg 10 and the PCBA board 1, so as to connect and fix the PCBA board 1 and the mounting frame 6. Then insert the connecting abutting rod 14 into the inner side of the threaded mounting hole 7, and rotate the hexagonal block 16 with a tool to make the mounting sleeve 11 and the mounting thread 15 rotate. Install the mounting sleeve 11 in the threaded mounting hole 7, and the bottom end of the connecting abutting rod 14 can always contact the top of the electronic component when the movable mounting disk 13 is acted on by the force spring 12, so that the electronic component and the PCBA board 1 can always be kept in a stable state and avoid loosening. Then quickly sleeved the auxiliary positioning sleeve 5 on the outer surface of the mounting column under the action of the guiding arc surface 18 and the fixed through groove 17, and then rotate the bolt and insert it into the inner side of the fixed mounting hole 4 and the inside of the mounting column to install and fix the whole PCBA board 1, so as to install and use the PCBA board 1. The overall structure is simple and the use is convenient and fast.

[0040] The above embodiments only express the specific implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the patent scope of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model.
