[0001] This utility model relates to the field of PCB boards, specifically to a PCB board connection structure and a PCB board assembly. Background Technology

[0002] A PCB, or printed circuit board, is a basic material used to connect electronic components. In electronic devices, the PCB serves as a support and connection platform, enabling electrical connections, signal transmission, and power supply for circuits. PCBs are widely used in various electronic products, including mobile phones, computers, home appliances, automobiles, and communication equipment.

[0003] When mounting existing PCBs onto a housing, they are usually fixed by tightening screws or by gluing. However, tightening screws requires tools such as screwdrivers, and there are many screws, so tightening and loosening is not quick. Although gluing is convenient for installation, subsequent disassembly is troublesome.

[0004] Therefore, it is necessary to invent a PCB board connection structure and a PCB board assembly. Utility Model Content

[0005] To address this issue, the present invention provides a PCB board connection structure and a PCB board assembly, which solves the problem that existing PCB boards are usually fixed by screwing or bonding when installed on a housing. However, screwing requires tools such as screwdrivers, and there are many screws, making tightening and loosening slow. While bonding is convenient for installation, subsequent disassembly is troublesome.

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0023] Please refer to the appendix. Figures 1-5 The present invention provides a PCB board connection structure, including a housing 1 and a PCB board 2, wherein the PCB board 2 is detachably installed inside the housing 1 by means of a snap-fit ​​assembly;

[0024] The snap-fit ​​assembly includes two snap-fit ​​seats 3. The bottom ends of the two snap-fit ​​seats 3 are symmetrically fixed to the bottom of the inner wall of the housing 1. A support base plate 4 is fixed to the bottom end of each snap-fit ​​seat 3. The PCB board 2 is located between the two snap-fit ​​seats 3. The top end of the support base plate 4 is in contact with the bottom of the PCB board 2. Each snap-fit ​​seat 3 has a receiving groove 5. Limiting guide rods 6 are symmetrically fixed in the receiving groove 5. Specifically, the support base plate 4 can be used to support and place the PCB board 2.

[0025] Furthermore, the snap-fit ​​assembly also includes a sliding piece 7, which is located in the receiving groove 5. Both ends of the sliding piece 7 are symmetrically provided with limiting sliding holes 8. The limiting guide rod 6 passes through the limiting sliding hole 8, and the surface of the limiting guide rod 6 is in contact with the hole wall of the limiting sliding hole 8. A return spring 9 is fixed at the end of the sliding piece 7 away from the PCB board 2. The end of the return spring 9 away from the sliding piece 7 is fixed on the inner surface of the receiving groove 5. Specifically, under the combined limiting action of the limiting sliding hole 8 and the limiting guide rod 6, the sliding piece 7 can move stably in a straight line. When the sliding piece 7 is moved by force, it can squeeze the return spring 9, causing the return spring 9 to undergo elastic deformation and generate elastic force. Under the action of this elastic force, when the force on the sliding piece 7 disappears, it can push the sliding piece 7 to move back to its original position.

[0026] Furthermore, each of the card holders 3 has a through hole 10 at one end near the PCB board 2, and the through hole 10 is connected to the receiving groove 5. Each of the sliding pieces 7 has a locking pin 11 at one end near the PCB board 2. The locking pin 11 passes through the through hole 10, and the bottom of the locking pin 11 is in contact with the top of the PCB board 2. Specifically, under the blocking action of the locking pin 11, the PCB board 2 can be locked between the two card holders 3, thereby realizing the fixed installation of the PCB board 2. The locking pin 11 can move back and forth in a straight line synchronously with the sliding piece 7.

[0027] Furthermore, each of the card holders 3 has a strip hole 12 at its top, which is connected to the receiving groove 5. Each of the sliding pieces 7 has a vertically fixed actuating piece 13 at its top, which passes through the strip hole 12 and the surface of the actuating piece 13 is in contact with the wall of the strip hole 12. Specifically, when the operator needs to disassemble the PCB board 2, the sliding piece 7 can be pushed by the actuating piece 13, so that the sliding piece 7 is moved by force, thereby driving the locking pin 11 to move synchronously. Once the locking pin 11 no longer blocks the PCB board 2, the PCB board 2 can be taken out from the housing 1. Therefore, this PCB board connection structure allows the PCB board 2 to be quickly locked between the two card holders 3, so that the PCB board 2 can be quickly installed and removed from the housing 1. It is convenient to use and has a simple structure.

[0028] A PCB board assembly includes the aforementioned PCB board connection structure and a plurality of limiting rods 14. The bottom ends of the limiting rods 14 are all fixed to the bottom of the inner wall of the housing 1. Limiting holes 15 are provided at the corners of the PCB board 2. The top ends of the limiting rods 14 pass through the limiting holes 15 respectively. The surface of the limiting rods 14 is in contact with the wall of the limiting holes 15. Specifically, under the combined limiting action of the limiting rods 14 and the limiting holes 15, the PCB board 2 fixedly installed in the housing 1 can be positioned at multiple points to prevent the PCB board 2 from shaking or shifting, and to ensure that the PCB board 2 is stably fixed and installed.

[0029] The usage process of this utility model is as follows: When it is necessary to fix the PCB board 2 in the housing 1, the operator can first move the sliding piece 7 by using the toggle piece 13 to make the two locking pins 11 move in opposite directions to open. Then, the PCB board 2 is placed between the two locking seats 3, and the limiting insertion hole 15 on the PCB board 2 is aligned with the limiting insertion rod 14 in the housing 1. Then, the PCB board 2 is pressed onto the support base plate 4, and the toggle piece 13 is released, so that the sliding piece 7 moves in the opposite direction to its original position under the elastic force of the return spring 9, so that the two locking pins 11 move towards each other, thereby making the PCB board 2 locked between the two locking seats 3, thus realizing the fixed installation of the PCB board 2. Under the combined limiting action of the limiting insertion rod 14 and the limiting insertion hole 15, the PCB board 2 fixedly installed in the housing 1 can be positioned at multiple points to prevent the PCB board 2 from shaking or shifting, and to ensure the stable fixed installation of the PCB board 2.

[0030] When the operator needs to disassemble the PCB board 2, the sliding piece 7 can be pushed by the toggle piece 13, so that the sliding piece 7 moves under force, thereby driving the locking pin 11 to move synchronously. Once the locking pin 11 no longer blocks the PCB board 2, the PCB board 2 can be taken out from the housing 1. Therefore, this PCB board connection structure allows the PCB board 2 to be quickly locked between the two locking seats 3, so that the PCB board 2 can be quickly installed and removed from the housing 1. It is convenient to use and has a simple structure.

[0031] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art can modify this utility model or modify it into an equivalent technical solution using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solution of this utility model are within the scope of protection claimed by this utility model.
