NOVELTY - The utility model claims an anti-shielding filter, comprising a filter main body; the outer side of the filter main body is provided with a shell; the shell is provided with an interlayer; the interlayer is provided with a shielding layer; the inner side of the shell is fixedly connected with a plurality of clamping blocks; the filter main body is clamped between a plurality of clamping blocks; the top end of the shell is provided with a top cover; the top cover is fixedly connected with the shell through the bolt; by setting the graphene shielding layer; when the filter is in the working state, only receiving signal by the antenna; then performing signal selection by the filter; The circuit of the filter itself processing signal can completely isolate the influence of the external electromagnetic wave, so that the filter only processes the waveform of the signal receiving end, ensuring the use effect of the filter is maximized. The filter main body of the utility model is integrally clamped in the shell; the filter can be conveniently taken out by dismounting the top cover; it is convenient to install and take out the filter; it is convenient for subsequent maintenance.
