Description

Technical Field

[0001] The utility model relates to the technical field of circuit board protection, in particular to a fireproof circuit board with high stability. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards miniaturize and visualize circuits, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts.

[0003] Circuit boards are usually installed directly inside electrical equipment. When external equipment is running, vibration will be transmitted to the circuit board, which will cause resonance of the circuit board. Over time, the electrical components on the circuit board will become desoldered. Based on this, a highly stable fireproof circuit board is proposed to solve the above problem. Utility Model Content

The limiting groove in this scheme adopts a stepped structure, which is convenient for matching with the edge position of the upper cover, so that the top surface of the upper cover and the top surface of the protective shell remain relatively parallel, making it have a higher aesthetics. At the same time, the upper cover is limited so that a certain distance is left between the bottom surface of the upper cover and the circuit board body, thereby protecting the circuit board body.

The materials of the first fireproof layer and the second fireproof layer in this scheme are both fireproof felt or high-temperature ceramic fiber woven products, which themselves have high temperature resistance, thereby facilitating a certain isolation of the circuit board body from the external environment, thereby achieving better protective performance. At the same time, the plurality of air holes facilitate air circulation between the protective shell and the external environment.

[0008] Preferably, any of the above schemes has one end of the four limit holders that is away from each other being designed to be open, and the other ends of the four are all facing the center direction of the protective shell. By using this scheme, the four limit holders can be evenly distributed at the four corners of the circuit board body, thereby facilitating a certain protection of the circuit board body.
