BLADE MATERIAL FOR MAGNETIC SHIELD AND LOUVER BODY FOR MAGNETIC SHIELDING

摘要

A blade material for magnetic shielding, capable of forming an open shield structure having stable performance, and a louver body for magnetic shielding. Magnetic plates (5) are placed in non-magnetic sheathes (10) to form blade members (1). Each magnetic plate (5) has a rectangular cross-section when cut in the direction intersecting the longitudinal direction of the plate, and the dimension along the short sides of the rectangle is defined as the thickness of the plate. Each non-magnetic sheath (10) is sized so that bending rigidity in the longitudinal direction of the sheath prevents deflection of the magnetic plate (5). The blade members (1) are laid over each other in the form of a set of louvers with a predetermined distance (d) between them in the plate thickness direction and are supported by support members (20) in a beam-like form. The blade members (1) are in parallel to each other such that the longitudinal center axes (C) of the magnetic plates (5) of the blade members (1) are in parallel with each other on the same plane of the set of louvers. Thus the louver body for magnetic shielding is formed.
