The invention provides a device which has a simple structure and is convenient to detach; under the condition of unchanged reinforcement size, the gap contact length between the panel and the panel contact surface (comprising between an upper panel and an upper sliding rail and an upper sliding groove of four panels, between a lower panel and a lower sliding rail and a lower sliding groove of four panels and between two edges and cutter slots of four panels) is increased through edge seal, so that the totally-enclosed reinforcement chassis with electromagnetic compatibility is ensured.
The invention solves the problems of poor electromagnetic compatibility and the like caused by gaps in case disassembly, and can be deduced according to a Maxwell Wei Weifen equation:
namely, under the condition of keeping the transfer impedance unchanged, the electromagnetic field leaked through the equivalent gap model is reduced along with the increase of the width of the gap, if the gap is widened to 10 times of the original width, the leakage field strength is reduced to be l/10 of the original leakage field strength, and the total energy of the electromagnetic field leaked through the gap is in direct proportion to the product of the electric field and the area of the gap:
ws represents the total energy of the electromagnetic field leaking through the slot, S represents the leakage area, h represents the slot width, and l represents the slot length.
When the transfer impedance 1=2 is maintained, if the width of the slit is increased to be 1 times of the original h2/h, the leakage electric field E2 of the equivalent model is reduced to be 1/h2, and the total energy Ws of the leakage generated by the same radiation source through the equivalent model is reduced to be 1/h2. Therefore, the electromagnetic shielding effectiveness of the equipment can be enhanced by effectively increasing the gap contact length.
