Description

Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to a circuit board which is easy to disassemble and assemble. Background Art

[0002] A circuit board, also known as an electronic circuit board or PCB, is one of the most important components in electronic devices. It provides electrical connections between the various components inside electronic devices, allowing current to flow according to the designed circuit, thereby realizing the function of the device. A circuit board is usually composed of an insulating substrate and a conductive layer. The conductive layer is formed into the required circuit pattern through etching or other processes, and the components are fixed to the circuit board through welding or other connection methods.

[0003] When existing circuit boards are in use, they are usually fixed and installed directly using screws. Although this can ensure the stability of the circuit board fixation, it is not conducive to the disassembly, maintenance and cleaning of the circuit board. A large number of screws need to be tightened during later maintenance, which is cumbersome and affects the maintenance efficiency. At the same time, the circuit board is easily damaged when installing with screws.

[0004] For example, a circuit board disclosed in the announcement number CN219019110U, the circuit board in this patent is mainly assembled to the equipment on which the circuit board needs to be assembled by bolting the mounting ears, but the use of multiple screws when installing the circuit board means that more time and effort are required to tighten the screws one by one. When the circuit board needs to be disassembled, the presence of multiple screws makes the disassembly process cumbersome and difficult, which not only increases the complexity of the circuit board disassembly process, but may also lead to extended disassembly time and reduced production efficiency.

[0005] Therefore, it is necessary to invent a circuit board that is easy to disassemble and assemble to solve the above problems. Utility Model Content

This matching design not only provides a good guiding effect, but also ensures the stability and reliability of the connection.

[0010] Preferably, the shaft seat and the adjustment plate are hingedly connected, and 8 shaft seats and adjustment plates are provided. The eight shaft seats and adjustment plates constitute four groups, and each group is provided with two shaft seats and adjustment plates, so that the adjustment plate can be adjusted relative to the shaft seat within a certain angle range, thereby adjusting the position of the positioning plate.

[0011] Preferably, the positioning plate is arranged on the left and right sides of the circuit board body, and the positioning plate is designed in a disc-shaped structure. An anti-slip pad is fixedly installed on the bottom of the positioning plate, so that the positioning plate can press down and fix the circuit board body, thereby limiting and fixing the installation of the circuit board body to ensure the stability of the installation of the circuit board body.

[0012] Preferably, the anti-skid pad is a silicone pad, which is fixed to the positioning plate by adhesive, and is in contact with the circuit board body. The main function of the anti-skid pad is to increase the friction between the positioning plate and the circuit board body to prevent the two from slipping or dislocating when subjected to external force.

[0013] Preferably, a heat dissipation hole is provided directly below the circuit board body, and a plurality of the heat dissipation holes are provided, and the plurality of heat dissipation holes are evenly distributed in a rectangular array, so that the heat dissipation holes can smoothly conduct and dissipate the heat generated by the circuit board body to the external environment.

[0027] The insertion rod 6 and the slot 7 are snap-fitted together, and the outer diameter of the insertion rod 6 matches the inner diameter of the slot 7. The shaft seat 8 and the adjustment plate 9 are hingedly connected. There are eight shaft seats 8 and adjustment plates 9, and the eight shaft seats 8 and adjustment plates 9 constitute four groups. Each group is provided with two shaft seats 8 and adjustment plates 9. The positioning plate 11 is arranged on the left and right sides of the circuit board body 5. The positioning plate 11 is designed in a disc-shaped structure. An anti-skid pad 12 is fixedly installed on the bottom of the positioning plate 11. The anti-skid pad 12 is a silicone pad. The anti-skid pad 12 and the positioning plate 11 are fixed by adhesive, and the anti-skid pad 12 is in contact with the circuit board body 5.
