Novel anti-interference protective shell of microelectronic circuit

Abstract

The utility model relates to the technical field of electronic circuit equipment, in particular to a novel microelectronic circuit anti-interference protective shell which comprises a PCB substrate, a protective assembly is arranged on the top of the PCB substrate, and a shell positioning clamping block is arranged on one side of the protective assembly; the shielding shell body, the outer insulation isolation layer and the inner insulation isolation layer form a multi-layer protection structure, external electromagnetic interference can be effectively prevented from entering an internal microelectronic circuit, meanwhile, electromagnetic signals generated by the internal circuit are prevented from being leaked, interference to other equipment is reduced, and the annular shielding plug is made of electromagnetic shielding composite materials. The shielding effect on electromagnetic signals can be further enhanced, and the anti-interference performance is improved by cooperating with the overall structure. The matching of the clamping cap and the clamping column enables the connection between the L-shaped sealing strip and the shielding housing body to be stable and reliable, thereby guaranteeing that all parts do not generate relative displacement in the use process, and guaranteeing the stability of the protection structure.
