A circuit protection structure is disclosed. The circuit protection structure comprises: a printed circuit board PCB (11), having thereon an electronic unit (111) and a grounded wireframe (12) surrounding the circuit unit (111); a conductive housing (14), having a receiving cavity to receive the circuit unit (111); and a conductive adhesive layer (13), provided between the grounded wireframe (12) and the conductive housing (14) for electrical connection between the grounded wireframe (12) and the conductive housing (14). In the present disclosure, the electronic unit (111) is protected by forming a Faraday cage structure by means of the combination of the conductive housing (14), the conductive adhesive layer (13), and the grounded wireframe (12) on the PCB (11), for the purpose of shielding the electromagnetic radiation so as to eliminate or reduce the electromagnetic radiation interference on the electronic unit (111), without increasing weight and size of the product caused by additional shielding conductive cover, and thus improving competitiveness of the product. |
