Description

Technical Field

[0001] The utility model relates to the technical field of PCB boards, and specifically relates to an explosion-proof structure for a PCB board and a PCB board. Background Art

[0002] The PCB board, whose Chinese name is printed circuit board and is also called printed wiring board, is called a "printed" circuit board because it is made by electronic printing technology. The printed board has developed from single-layer to double-sided, multi-layer and flexible, and still maintains its respective development trends. Due to the continuous development towards high precision, high density and high reliability, continuously reducing volume, cost and improving performance, the printed board still maintains strong vitality in the development process of future electronic devices. However, during the use of the current PCB board, it is usually installed in an electronic device using bolts. If the bolts are tightened too hard, the corners of the PCB board will burst. Moreover, when the electronic device falls or is knocked or impacted, due to the lack of a corresponding buffer structure, it will also cause the PCB board to crack and then burst, which will affect the normal use of the PCB board at this time. Therefore, we propose an explosion-proof structure for a PCB board and a PCB board to solve the above problems. Content of the Utility Model

Specific implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment

[0025] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, an explosion-proof structure for a PCB board and a PCB board proposed in an embodiment of the present invention include a bottom plate 1. Two mounting plates 14 are fixed to the bottom of the bottom plate 1. Two mounting holes 15 are opened at the top of each mounting plate 14, which makes it more convenient to install and fix the bottom plate 1. Four guide seats 2 are fixed to the top of the bottom plate 1. A protective frame 3 is arranged inside the four guide seats 2. The PCB board body 4 is placed in the sinking groove opened at the top of the protective frame 3. Two guide plates 5 are fixed to each of the guide seats 2. Damping buffers 6 are fixed to one side wall of each guide plate 5. The other ends of the damping buffers 6 are fixed to a moving frame 7. Four sliding grooves 12 are opened on each of the guide seats 2. Two sliders 13 adapted to the sliding grooves 12 are opened on both side walls of the moving frame 7, which can play a role in guiding and supporting the moving frame 7, so that it will be more stable during the sliding process. Steel wire ropes 8 are fixed to one side wall of each moving frame 7. The other ends of the steel wire ropes 8 are fixedly connected to the protective frame 3. Two groups of limit components 9 for fixing the PCB board body 4 are arranged at the top of the protective frame 3. When using this PCB board, the bottom plate 1 can be installed on an electronic device. When the electronic device is dropped or impacted, at this time, the protective frame 3 will drive the steel wire rope 8 to move after being subjected to a force. After the steel wire rope 8 moves, it will drive the moving frame 7 to move, and after the moving frame 7 moves, it will squeeze the damping buffer 6. At this time, under the action of the damping buffer 6, the force received by the protective frame 3 can be buffered, thereby avoiding the situation that the PCB board body 4 bursts after being damaged.

[0026] As Figure 1 and Figure 6As shown, in some embodiments, a limiting component 9 slides on a sliding block 901 inside a T-shaped slot of a protective frame 3. A spring 902 is fixed to the top of the sliding block 901, and a clamping plate 903 is fixed to the top end of the spring 902. A telescopic rod 905 is fixed to the top of the sliding block 901, and the top end of the telescopic rod 905 is fixedly connected to the bottom of the clamping plate 903, which can play a role in guiding and supporting the clamping plate 903 to make it more stable when moving upward. A through hole is formed in the top of the clamping plate 903, and a clamping frame 904 adapted to the clamping plate 903 is fixed to the top of the PCB board body 4. The clamping plate 903 is limited and clamped inside the clamping frame 904. When it is necessary to separate the PCB board body 4 from the protective frame 3, the clamping plate 903 can be moved upward to disengage from the clamping frame 904, and then the clamping plate 903 can be moved to one side. At this time, the PCB board body 4 will no longer be blocked, and then it can be removed. During installation, after placing the PCB board body 4 on the protective frame 3, pull the clamping plate 903 upward and move it towards the clamping frame 904. After it moves to the maximum extent, release the clamping plate 903. At this time, under the reset force of the stretched spring 902, the clamping plate 903 can be clamped inside the clamping frame 904, and at this time, the PCB board body 4 can be installed and fixed.

[0027] As Figure 2 shown, in some embodiments, baffles 10 are fixed at both through openings formed in the top of the bottom plate 1, and heat dissipation fans 11 are fixed inside the baffles 10. By using the provided heat dissipation fans 11, the PCB board body 4 can be quickly cooled down.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
