Zusammenfassung:The invention discloses a shielding packaging body which comprises a metal enclosure, a shielding film body and an isolation shielding body, the bottom of the metal enclosure is welded to a grounding area on a circuit board, a shielding space is defined by the metal enclosure on the circuit board, and the shielding film body covers the top of the metal enclosure to seal the shielding space. The shielding film body is arranged in the shielding space and electrically communicated with the metal enclosure, the isolation shielding body is arranged in the shielding space, the top and the bottom of the isolation shielding body are correspondingly connected with the shielding film body and the circuit board and electrically communicated with the shielding film body and the circuit board, and the isolation shielding body divides the shielding space into at least two sub-shielding cavities which are mutually closed. According to the shielding packaging body, the connection reliability can be ensured, the service life
