[0002] A circuit board is a carrier on which conductive lines are formed on an insulating substrate through physical etching or chemical deposition processes. It is commonly referred to as a printed circuit board and serves as a substrate in electronic devices to support and connect electronic components, enabling electrical connections and mechanical fixation.

[0003] During the design and development phase of a circuit board, some cards may be installed on the circuit board. Existing cards are locked to the circuit board with fasteners such as screws. However, this installation method is not easy to disassemble, and the cards are easily damaged during disassembly. Utility Model Content

[0004] The purpose of this utility model is to provide a plug-in structure for circuit board components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plug-in structure for circuit board components, comprising a circuit board and a card, wherein a positioning block is fixedly connected to the circuit board, a plug plate is fixedly connected to one side of the card, the positioning block is provided with a slot corresponding to the plug plate, a positioning sleeve is fixedly sleeved on the plug plate, a swing plate is provided at both ends of the positioning sleeve, a groove is provided at one end of the swing plate, the swing plate is engaged on the positioning sleeve, the inner walls on both sides of the swing plate are rotatably connected to the positioning sleeve through a torsion spring shaft, a connecting block is fixedly connected to one end of the swing plate, an installation block is fixedly connected to one end of the connecting block, a stop block is fixedly connected to one side of the installation block, and a stop groove corresponding to the stop block is provided on the positioning block.

[0006] Preferably, the positioning block is provided with a receiving groove communicating with the stop groove, and a pressing rod is provided in the receiving groove. A connecting sleeve is fixedly sleeved on one end of the pressing rod, and springs are fixedly connected between both ends of the connecting sleeve and the positioning block. The side of the stop block near the pressing rod is provided with a beveled section.

[0007] Preferably, the connecting block is inclined.

[0008] Preferably, the stop block has an arc-shaped surface on the side near the positioning block.

[0009] Preferably, the inner wall of the groove on the swing plate abuts against the side wall of the positioning sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] The plug-in structure of this circuit board component involves inserting the plug-in plate on the board into the slot on the positioning block. During the insertion process, the stop block presses against the edge of the positioning block, while the initial mounting block of the stop block moves. The mounting block drives the swing plate to flip through the connecting block. When the swing plate flips, it causes the torsion spring shaft to rotate and generate torque. After the plug-in plate is fully inserted, the stop block corresponds to the position of the stop slot. At this time, the rotational torque of the torsion spring shaft makes the stop block firmly locked inside the stop slot. The plug-in fixing component of this utility model can lock the board onto the motherboard, which is time-saving, convenient, and easy to disassemble. Attached Figure Description

[0020] Please see Figure 1-4 This utility model provides an embodiment of a circuit board component insertion structure, including a circuit board 1 and a board card 2. A positioning block 3 is fixedly connected to the circuit board 1, and an insertion plate 4 is fixedly connected to one side of the board card 2. The positioning block 3 has a slot corresponding to the insertion plate 4. A positioning sleeve 5 is fixedly sleeved on the insertion plate 4. Both ends of the positioning sleeve 5 are provided with swing plates 6. One end of the swing plate 6 has a groove. The swing plate 6 is clipped onto the positioning sleeve 5. The inner walls of both sides of the swing plate 6 are rotatably connected to the positioning sleeve 5 through a torsion spring shaft 7. A connecting block 8 is fixedly connected to one end of the swing plate 6, and a mounting plate is fixedly connected to one end of the connecting block 8. Mounting block 9 has a stop block 10 fixedly connected to one side. Positioning block 3 has a stop groove corresponding to the stop block 10. Specifically, the insert plate 4 on the board 2 is aligned with the slot on the positioning block 3 and inserted. During the insertion process, the stop block 10 will press against the edge of the positioning block 3. At the same time, the stop block 10 initially moves the mounting block 9. The mounting block 9 drives the swing plate 6 to flip through the connecting block 8. When the swing plate 6 flips, it causes the torsion spring shaft 7 to rotate and generate torque. After the insert plate 4 is fully inserted, the stop block 10 corresponds to the position of the stop groove. At this time, the rotational torque of the torsion spring shaft 7 is used to make the stop block 10 firmly locked in the stop groove.

[0021] In this embodiment, the positioning block 3 is provided with a receiving groove communicating with the stop groove. A pressing rod 11 is provided in the receiving groove. A connecting sleeve 12 is fixedly sleeved on one end of the pressing rod 11. Springs 13 are fixedly connected to both ends of the connecting sleeve 12 and the positioning block 3. The side of the stop block 10 near the pressing rod 11 is provided with a beveled section 14. By pushing the pressing rod 11, one end of the pressing rod 11 presses against the beveled section 14 of the stop block 10 and moves from the wide side to the narrow side. At this time, the stop block 10 moves under the action of the pressing force. Then, the plate 2 is dragged to make the stop block 10 disengage from the stop groove. The connecting block 8 is inclined. The side of the stop block 10 near the positioning block 3 is provided with an arc-shaped surface 15 to reduce the resistance when pressing against the positioning block 3. The inner wall of the groove on the swing plate 6 abuts against the side wall of the positioning sleeve 5 to keep the mounting block 9 in a parallel state in the initial state.

[0022] The working principle of the plug-in structure of this circuit board component is described in detail below: First, the plug-in board on the board is aligned with the slot on the positioning block and inserted. During the insertion process, the stop block will press against the edge of the positioning block. At the same time, the initial mounting block of the stop block moves. The mounting block drives the swing plate to flip through the connecting block. When the swing plate flips, it causes the torsion spring shaft to rotate and generate torque. After the plug-in board is fully inserted, the stop block and the stop groove are aligned. At this time, the rotational torque of the torsion spring shaft is used to make the stop block firmly locked in the stop groove.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
