Patent ID: 7626127

Claim:
A shield structure for covering a section to be shielded on a surface of a circuit board, the shield structure comprising: a plurality of hollow columnar base members arranged with intervals therebetween along a periphery of the section to be shielded on the surface of the circuit board, each of the plurality of base members being in a horizontal orientation such that a peripheral surface of each base member extends along the surface of the circuit board; and a shield cover having a cover plate that covers the section to be shielded on the circuit board, and a peripheral wall that extends from a periphery of the cover plate, the peripheral wall having insertion pieces arranged at intervals along an edge of the peripheral wall corresponding to the respective arrangement positions of the plurality of base members, each base member having a rectangular prism shape and all four side surfaces of the base member having a respective cut formed at least in a section thereof, each respective cut forming an elastically deformable tongue portion having a free end at a position where a corresponding insertion piece of the shield cover can be inserted, the tongue portion being elastically deformable toward an inner space of the respective base member by an insertion force applied when the corresponding insertion piece of the shield cover is inserted into the cut, the tongue portion retaining and fixing the shield cover on the base members by applying an elastic resilient force such that the free end thereof presses against the corresponding insertion piece of the shield cover.
