Problems solved by technology
Traditional circuit boards are fixed inside the chassis by screwing bolts. Although this connection method is simple, the circuit board needs to be disassembled and cleaned for maintenance from time to time during use, and repeated screw rotations may easily lead to tooth slippage. It is difficult to fix or disassemble, which increases the difficulty of disassembly and assembly. At the same time, the existing circuit board is slightly insufficient in terms of shock absorption. Especially during the transportation of the equipment, it is easy to cause loosening and failure of components on the circuit board due to bumps, which increases maintenance costs. Therefore, , those skilled in the art provide a circuit board that is convenient for fixed installation, to solve the problems raised in the above-mentioned background technology

The invention relates to the technical field of circuit boards, in particular to a circuit board convenient to fixedly install. The circuit board is assembled above a support, the circuit board and the support are fixedly connected through a disassembly and assembly mechanism, and a heating element independent heat dissipation assembly is assembled at the position, located in a heating element installation area, above the circuit board. And a damping part is arranged between the support and the circuit board. The circuit board is novel in design and simple in structure, the circuit board is convenient to mount, dismount and mount through the disassembly and assembly mechanism, tools are not needed, the disassembly and assembly difficulty is reduced, the defects of traditional screw fixing are overcome, maintenance is more convenient, and the circuit board can have a certain degree of damping function through the damping part, the problem that elements fail due to jolt in the conveying process of equipment is solved, the maintenance cost is reduced, the practicability is improved, the heating element independent heat dissipation assembly can conduct independent heat dissipation on the elements with large power on the circuit board, the heat dissipation effect is improved, and the due performance of the elements is guaranteed.
Description
technical field [0001] The invention relates to the technical field of circuit boards, in particular to a circuit board which is convenient for fixed installation. Background technique [0002] The circuit board can be called a printed circuit board or a printed circuit board, and the circuit board is generally assembled inside the equipment control box. Traditional circuit boards are fixed inside the chassis by screwing bolts. Although this connection method is simple, the circuit board needs to be disassembled and cleaned for maintenance from time to time during use, and repeated screw rotations may easily lead to tooth slippage. It is difficult to fix or disassemble, which increases the difficulty of disassembly and assembly. At the same time, the existing circuit board is slightly insufficient in terms of shock absorption. Especially during the transportation of the equipment, it is easy to cause loosening and failure of components on the circuit board due to bumps, whic...
